Cold storage board installation three tips to better maintain the cold storage
In the refrigeration industry, the cold storage board with relatively low technical requirements has attracted a large amount of personnel and capital investment. The choice of cold storage board is very important for the cold storage, because the cold storage is different from the ordinary warehouse, the temperature inside the cold storage is generally low, and the air temperature, humidity, and environmental requirements are relatively high. high. Therefore, when choosing the cold storage board, we must pay attention to the cold storage board which is better for temperature control. If the cold storage board is not well selected, the temperature inside the cold storage is difficult to control, it will easily lead to deterioration of the products stored in the cold storage. Or let the cold storage refrigeration compressor work frequently, waste more resources and increase costs. Choosing the right plate will better maintain the cold storage. Today, Xiaobian mainly focuses on the installation of cold wall panels in terms of the installation of wall panels, the installation of roof panels and the installation of angled panels. Wall panel installation 1. The installation of the wallboard should start from the corner. According to the layout diagram, transport the two plates at the corners to be installed to the installation site. According to the height of the plate beam and the angle iron model of the fixed mushroom head nylon bolt, drill a hole in the corresponding elevation position in the middle of the plate width. The surface of the board is vertical, and the mushroom head nylon bolt is put in the hole (the nylon bolt body and the mushroom head should be sealed with a sealing paste), and the angle iron piece is tightened, so that the degree of tightening of the nylon plate bolt on the board surface is suitable. When erecting wall panels, soft materials such as foam should be placed on the floor troughs in contact with the slabs to prevent damage to the slabs. After the two corners are erected from the slab floor troughs, the wall slabs should be adjusted according to the position of the splicing line. The position of the plane and the verticality of the library board, and check whether the top level of the wall panel is correct (check all the way from the beginning to the end). After the wall panel is in the correct position, the angle iron piece is welded on the plate beam, and the inner outer corner is fixed (the inner side of the gusset plate is sealed with the sealing plate at the inner side of the gusset plate). When welding the angle iron piece, the angle part of the plate plate should be covered with the covering object to prevent the high temperature baking plate and the welding slag of the electric welding from splashing onto the library plate during the arc welding. 2. After the two wall panels at the corner are installed, start installing the next wall panel along the corner. Before the next wall panel is installed, two white sealing pastes should be placed on the ground in the convex groove or groove of the library plate (the sealing paste should be placed at the corner of the groove or groove of the library plate), and it should be placed in the convex groove or concave. The sealing paste in the tank should have a certain height, and should be dense and continuous, and the installation method is the same as that of the *wall panel. 3. First hit the square wood on the polyurethane library board with a hammer between the two library boards, so that the board and the board are closely close together. The two sets of connecting members are wedged between the wall panel and the wall panel, and the two connecting members are respectively fixed on the upper outer side and the lower inner side of the gap between the wall panel and the wall panel, and the connecting members on the lower inner side should be as close as possible so that the post-cast concrete can Cover the connector. The gap between the board and the board should be kept at about 3mm width after being wedged by the connecting piece. If it does not meet the nuclear requirements, remove the board, trim the board edge, and then re-install it so that the board seam meets the requirements. When fixing the connecting piece, it is necessary to fix the two parts of the connecting piece to the edge of the two concave and convex plates, and fix it with the φ5X13 rivet. The distance of the connecting piece is suitable for tightening the two plates. When the wedge iron is wedged, the hammer and the wedge iron are kept perpendicular to avoid bumping the plate, and the wedge iron at the upper and lower parts should be wedged at the same time, and the wedge iron is fixed by the rivet. Roof installation 1. Before installing the top plate, the T-shaped iron for the ceiling should be installed according to the drawings. When installing T-shaped iron, the T-shaped iron should be properly arched according to the span of the rigid frame to ensure that the T-shaped iron does not produce downward deflection after the top plate is installed. The installation of the top plate should start from the corner of the storage body. According to the layout diagram, the library plate is raised to the specified height and position. The longitudinal plate ends of the library plate are placed on the wall panel and the T-shaped iron. Adjust the parallelism and verticality of the coaxial line of the top plate, check the elevation of the bottom surface of the top plate, and then fix the top plate with the T-shaped iron with rivets, connect the gusset plate between the top plate and the wall plate, and then start the next one. The installation of the library board. 2. The installation method of the second top board is basically the same as that of the * board, and the connection method of the board is basically the same as that of installing the wall board. The connecting plates of the library board should be fixed outside the library. Each library board joint should be fixed with three library board connecting pieces, one end of the board and one of the board (the top board can be less than 4 meters and two board connecting pieces can also be used). 3. After all the top plates are installed, the installation work of the ceiling C-shaped steel is started. According to the actual row of the top plate, the angle iron pieces of the mushroom head nylon bolts are fixed on the ground on the ceiling C-shaped steel according to the corresponding spacing. Then, the ceiling C-shaped steel is placed on the top plate according to the drawings, and the ceiling C-shaped steel should ensure the parallelism and verticality of the coaxial line. After adjusting the position of the ceiling C-shaped steel, the top plate is opened at the position of the bolt hole of the angle iron, and the angle iron piece is firmly connected with the library plate with the mushroom head nylon bolt. After that, the ceiling C-shaped steel round steel hanging piece is welded on the purlin. According to the bottom surface elevation of the top plate, the nut below the round steel hanging piece is adjusted to adjust the ceiling C-shaped steel and the top plate to a specified height. Angle plate installation A sealant is applied to the inside of both sides of the gusset plate of all the cold storages at the inner side of the gusset plate. The wrap angle between the wall panels should be fixed in sections to facilitate the pouring of polyurethane foam in the field. The angled plate of the fixed top plate should be cut with a slit every 500mm (the size of the gap is to be able to reach the foaming material), and then fixed on the top plate and the wall plate. The angled plate is fixed by rivets, and the distance between the rivets should be kept at 100mm. The rivets fixed on the wrap angle should be in a straight line with the same spacing. Pay attention to the drilling of the rivet and the rivet to fix the rivet. The tool used should be perpendicular to the gusset. 7 Inch Face Access Control,Face Recognition Access Control With Fingerprint,7 Inch Ultra Thin Face Recognition Terminal,Dual Camera Recognition Access Control System Chongqing Huifan Technology Co., Ltd , https://www.hfsecuritytech.com
