Fourth, horizontal continuous components (such as eaves line, waist line) and the corner of the treatment 1. Determine the gap at the component connection.Taking into account the wet and dry deformation and temperature deformation factors, horizontal continuous components must be between the expansion joints.Single length of not more than 2m of the components of its expansion joints width of not less than 5mm. Single length of more than 2m components, expansion joints should be 5-10mm wide. 2.There are three ways of gap handling between components: (1) clear seam. Similar to the real stone components, to maintain the natural seam effect. (2) half clear seam. With rubber strips (or plastic strips) seams, building sealant caulks. (3) dark seam. With rubber strips (or plastic strips) seams, building sealant caulking after scraping putty, brush paint, so that the seams and components on the same surface. (Note: semi-clear seam and dark seam treatment should not use cement mortar caulking.) 3. The length of each component must be determined by the factors such as the size of the building's axis, the position of the door and window, the change of the corner of the wall and the position of the wall expansion joint (settlement slit), so that the connecting seam position of the component and the building facade Harmonized symmetrical symmetry.And the size of the component is suitable for making and installing. Horizontal component length range can be between 1.2-2.4m. 4. The horizontal members at the corner of the building shall be designed as male and female corners and shall not be used for splicing. The length of the yin and yang angle can be between 0.3-1.2m. Fifth, the length of continuous continuous components (such as columns, vertical sets, etc.) length, seam way. 1. Determine the length of each component of the longitudinal continuous member according to the conditions of the facade, the structural conditions and the conditions of manufacture, transportation and installation. The longitudinal length of a single member is generally between 1.2 and 3.6 m. A column with a diameter greater than 800, such as a transport installation, can also be made to 5-6 m long to avoid or reduce cracks. 2.

Six, the combination of components (Such as the door and window sets, the combination of mountain flowers, columns and feet from the composition of the colonnade, etc.) should ensure that the proportion between the components of the appropriate relationship between the logical relationship is reasonable, seam processing can be the same with the horizontal continuous components.Flat continuous components (such as mountain tai stone, continuous laying of the decorative panels, etc.) shall be based on the detailed dimensions of the building facade drawing components to determine the structure of the transverse joints of the joints and the width of the joints (slot width optional 10-30mm).Calculate the detailed size and quantity of the irregularities required for stitching and closing, so as to avoid cutting the cutting members on site. The planar continuous member shall be disconnected at the building expansion joint (sinker). Seven, the connection of components and walls 1. The component is connected to the wall. (1) no waterproof requirements, available cement mortar to fill. (2) there are waterproof requirements, to be used to seal the seal or other waterproof material. 2. The connection between the component and the wall change (such as cornice, window, door, balcony, rain Peng, water outlet, wall mutations and corners) should be based on the actual design of detailed nodes. In the edge of the site to pay special attention to the installation of bolts to split the possibility of the wall, so the location of the components to ensure that the installation of the bolt from the edge to ensure a certain distance. 3. The relationship between falling water pipes, plug-in equipment (such as air conditioners) and components. Eight, highlight the wall with water may be the components of the drainage should consider the slope. The wall members can be routed to the roof, with wall members should be discharged to the wall, the top surface drainage slope should be not less than 3%.For aerated concrete, hollow blocks, lightweight wall panels and hollow bricks and other lightweight walls and old buildings have been crisp or hollowed out of the wall, the design facade and optional components must consider the wall structure of the safety and reliability, To make the corresponding structural design and treatment program.

ShengFanjc GRC Introduction Chinese full name :Glass fiber reinforced cement composites English name :Glass fiber reinforced cement composites GRC(GFRC) Is the abbreviation of glass fiber reinforced cement composite material ,From the European and American technology, is the anti-alkali glass fiber, cement, sand and other composite materials according to a certain ratio of mixing, in the mold within the molding, to produce a rich shape, texture and diverse products, are widely used at home and abroad have their own characteristics In the building. GRC's cementitious material is cement, so GRC is also a concrete product, belonging to a branch of the concrete industry.Ordinary concrete compressive strength is high, but the bending strength, tensile strength and impact strength is low.GRC due to its incorporation of alkali-resistant glass fiber, making its performance in all aspects of the above compared to ordinary concrete has a qualitative leap, without reducing the advantages of concrete products in the case of GRC material significantly increased the cement products Bending strength, tensile strength, impact strength and reduce their own density. High-quality GRC products can reach the bending strength of 25Mpa, impact strength of 10-25KJ / m2, but its dry density of only 1800-2000kg / m3, lighter than the concrete products about 1/5.These features make the GRC a significant advantage over prefabricated concrete or other cement products, especially when a thin-walled material is required, the advantages of bending and impact strength will become more pronounced. GRC should be field GRC architectural details of decorative components, referred to as: GRC architectural details. GRC curtain wall board, or: GRC wall hanging board. GRC landscape products, such as: GRC sculpture, GRC rockery, GRC Pieces, GRC pots and so on. There are GRC light partition board, GRC insulation board, ventilation pipe, permanent tubular core mold, permanent template, industrial building roofing components, sound barrier, self-supporting floor, irrigation channel.

Glass Fiber Reinforced Gypsum (GFRG or GRG) is a white 'thin cast' alpha gypsum that is field finished, or may be factory finished depending on the specific application. Where once traditional 'plaster castings' were used, Glass Fiber Reinforced Gypsum (GFRG or GRG) is now specified because of its lightweight, superior strength and ease of installation. Glass Fiber Reinforced Gypsum (GFRG or GRG) is a white 'thin cast' alpha gypsum that is field finished, or may be factory finished depending on the specific application. Where once traditional 'plaster castings' were used, Glass Fiber Reinforced Gypsum (GFRG or GRG) is now specified because of its lightweight, superior strength and ease of installation. Glass Fiber Reinforced Gypsum (GFRG or GRG) is the bridge to shapes and curves for the drywall/plasterboard trades. With the move away from "less is more" in the late 1970's and the re-introduction of traditional architectural forms, GFRG (or GRG) evolved as the ideal medium. The construction boom of the past four decades established Glass Fiber Reinforced Gypsum as the means for architects and designers to achieve their design visions, while leveraging the experience of regular building trades. Today, Glass Fiber Reinforced Gypsum is used to achieve modern and "organic" shapes on walls and ceiling, in addition to traditional architectural shapes. Glass Fiber Reinforced Gypsum is a composite of high strength alpha gypsum reinforced with glassfibers that can be factory molded into virtually any shape or size. GFRG (or GRG) is a non-combustible material (test results of flame spread and smoke development values as per ASTM E-84) and even the largest parts only weigh 2-3 pounds per square foot (10-15 kg/m2). Similar to traditional plaster castings but considerably lighter and stronger, Glass Fiber Reinforced Gypsum is typically field finished with any interior paint. Joints can be taped and finishing is similar to drywall finishing. The use of post-consumer recycled material, the fact that GFRG castings are made to size and are designed to minimize excessive framing, makes Glass Fiber Reinforced Gypsum a favorable choice for LEED or green construction projects. Glass Fiber Reinforced Gypsum (GFRG or GRG) is the most economical Formglas material and is used in a range of architectural applications such as ceilings, column covers, decorative wall panels, domes, bulkheads, light coves, and more.

Advances in the science of concrete materials have led to the development of a new class of cementitious composites called ultra-high performance concrete (UHPC). The links above will direct you to pages detailing UHPC projects, bridges with UHPC components, articles that focus on UHPC research, and the main contact at Turner-Fairbank Highway Research Center (TFHRC) for UHPC. The mechanical and durability properties of UHPC make it an ideal candidate for use in developing new solutions to pressing concerns about highway infrastructure deterioration, repair, and replacement. Since 2000, when UHPC became commercially available in the United States, a series of research projects has demonstrated the capabilities of the material. A handful of State departments of transportation have deployed UHPC components within their infrastructure, and many more are actively considering the use of UHPC. UHPC is a cementitious composite material composed of an optimized gradation of granular constituents, a water-to-cementitious materials ratio less than 0.25, and a high percentage of discontinuous internal fiber reinforcement. The mechanical properties of UHPC include compressive strength greater than 21.7 kilopounds per square inch (ksi) (150 Megapascals (MPa)) and sustained postcracking tensile strength greater than 0.72 ksi (5 MPa). Ultra-high performance concrete has a discontinuous pore structure that reduces liquid ingress, significantly enhancing durability compared to conventional and high-performance concretes. UHPC is being considered for use in a wide variety of highway infrastructure applications. The high compressive and tensile strengths allow for the redesign and optimization of structural elements. Concurrently, the enhanced durability properties facilitate a lengthening of design life and allow for potential use as thin overlays, claddings, or shells. In the United States, UHPC has been used in prestressed concrete girder simple-span bridges, precast concrete deck panels, and field-cast connections between prefabricated bridge components. Figure 1 shows the first UHPC highway bridge constructed in the United States. Figure 1. This Wapello County, Iowa, structure was the first UHPC bridge constructed in the United States. The bridge includes three UHPC prestressed I-girders spanning a creek in rural Iowa.

Ultra High Performance Concrete (UHPC) is a fiber reinforced cementitious composite which has garnered widespread interest since its inception in the 1990s. Various barriers to market have been slowly overcome. It is now commonly applied as a connection material for precast elements in many bridge deck replacements as well as in new construction applications. At Precast Systems Engineering, we are imagining new uses for UHPC as a component in the bridge and marine construction applications as formwork and integral precast systems capable of meeting the challenges ahead in challenging environments.
