Quick and easy to close net

Hot dip galvanized steel sheet is a kind of one-way hot-dip galvanized steel sheet with one-way surface. It has excellent mechanical properties, light weight and heavy weight. It is especially suitable for pouring concrete in sections. It is advanced and widely practical, and can be used as consumption formwork. The closed net, also known as the template free net, is fixed as a consumable template. When the concrete is poured behind the formwork, the corner pieces on the mesh are embedded in the concrete to form a mechanical wedge connected with the adjacent pouring blocks. Joint quality shall be strictly controlled. The adhesive and shear strength of the composite is equivalent to that of the well treated rough cut suture. In the secondary pouring, drilling and roughening can be omitted, the construction period can be shortened and the strength of the pouring body can be increased. When the concrete is poured behind the formwork, the corner pieces on the mesh are embedded in the concrete to form a mechanical wedge connected with the adjacent pouring blocks. Joint quality shall be strictly controlled. Its strength in adhesion and shearing is comparable to that of a well treated rough cut sewing (Bimei). features: (1) good mechanical properties, small side pressure, equivalent to 60% of the general formwork bearing pressure, so the amount of formwork supporting keel can be reduced by 40%. (2) due to its special grid, the pouring process can be directly observed, and the pouring project can be monitored by naked eyes, so as to reduce the risk of blowholes and honeycombs. Due to the porosity of the net, the dense special grid is adopted, and the steel bars below 12mm can pass through with a little force. The larger diameter steel bar can cut the mesh, and the steel bar can return to its original position through the back plate. It is also possible to install a quick and simple closed net before binding the steel bars, and then pass through the net for correct installation. (3) light weight, convenient transportation and installation, the weight is only one tenth of the ordinary steel mold, installation is fast and convenient. (4) optimize the process and increase the shear interface. When pouring, the mortar infiltrates into the interface through the mesh, forming a coarse-grained interface with ideal shear performance. A complete template net includes two parts: V-shaped mesh and steel mesh surface. The stiffness of V-grid and the continuous parallel arrangement of V-grid are the main sources of strength of steel mesh. The steel mesh can be bent parallel to the V-shape. There are regular punching holes on the surface of steel mesh, and the protruding tooth plate on the punching hole can strengthen the combination of steel mesh and material. (5) it is convenient to pass reinforcement and bind reinforcement continuity. Due to the porosity of the closed net, the dense special grid is adopted, and the reinforcement below 12mm can pass through with a little force. The larger diameter steel bar can cut the mesh, and the steel bar can return to its original position through the back plate. It is also possible to install a quick and simple closed net before binding the steel bars, and then pass through the net for correct installation. (6) is suitable for the formwork which is poured in sections and has a long civilized construction time. It can bond with the next pouring concrete without removing the formwork or making joint preparation, which simplifies the interface preparation work. (7) the socket cutting operation is simple, multifunctional and easy to cut. It can be bent and shaped according to the required template shape. product use: due to its better mechanical strength and shape freedom than ordinary mold, it is very important in civil engineering of large-scale building. Such as the shape of high-rise buildings, such as subway, subway, subway, etc. , which can be used as long-term non demolition formwork of concrete. It is a simple and convenient method to close the seam. How to use it. It can be used with traditional support systems, and a center distance of 20 mm is sufficient for splints. After the concrete pouring is completed, the formwork net is combined with the concrete, and the angle embedding of the hole net will be automatically embedded into the permanent formwork. This has a strong mechanical bond to the next concrete placement. After concrete pouring, there is no need to remove the support, which saves time and effort and speeds up the construction progress. The quick and easy net retraction can be used vertically or horizontally, but the bracket must be at right angles to the skeleton. Ribs must always face the side ready to receive concrete. The mesh can be cut with iron scissors or grinder at the construction site. The grooves should be well buttressed with a V-shaped groove and connected to each other. The front and rear tailnets shall have an overlap opening of 150 mm and shall be well supported. The quick closing net can be used with all common support devices. Instead of removing the bracket, steel rods of suitable shape can be used instead of ordinary screws. The method of fixing on the bracket. It can be nailed to reinforced wood or wired to steel bars. Due to its special grid, the closed net can be used to monitor the pouring project with naked eyes, thus reducing the risk of voids and honeycombs. Its weight is only one tenth of the ordinary steel mold, installation is fast, convenient transportation. The permanent formwork can bond the concrete to be poured next time without removing the formwork or preparing the joint, which simplifies the interface preparation. The surface of adjacent formwork shall be overlapped, and the outer rib shall be tightened every 150 mm. The edge of the formwork surface shall be 150 mm beyond the support. The ribs can be placed horizontally or vertically to adapt to various situations when installing a quick and simple closed net. During casting, the supports restrain the form shell. The supporting part shall be at right angles to the formwork reinforcement and lean against the formwork. Special specifications can be customized.
