DETAILED DESCRIPTION

[0018] like Figure 1-Figure 3As shown, the utility model includes a plate body 1 and a locking rod 6. A plug-in connector 2 and / or a plug-in hole 3 are provided on the plate body 1. The plug-in hole 3 is used to cooperate with the plug-in connector 2 on the adjacent plate body 1. The plug-in hole 2 is a blind hole. An assembly hole 4 is provided on the plug-in connector 2. The assembly hole 4 is perpendicular to the plug-in connector 2. A fixing hole 5 is provided on the side of the plate body 1 horizontally adjacent to the plug-in hole 3. The fixing hole 5 is vertically connected to the plug-in hole 3. The locking rod 6 is connected to the fixing hole 5 and the assembly hole 4. The locking rod 6 fixes the plug-in connector 2 in the plug-in hole 3. When the plug-in connector 2 is inserted into the plug-in hole 3, the axes of the assembly hole 4 and the fixing hole 5 coincide.

[0019] The plug-in connector 2 and the plug-in hole 3 can be flexibly configured on the plate body 1 according to specific construction requirements. The plate body 1 can be provided with only the plug-in connector 2, or only the plug-in hole 3, or both at the same time to adapt to different connection methods, thereby improving the adaptability and flexibility of the formwork support.

[0020] There are several connectors 2 arranged in a line, and the number and position of the plug holes 3 correspond to the connectors 2, so that two adjacent boards can be firmly connected and evenly stressed during use, thereby enhancing the reliability of the connection.

[0021] A rod cap 7 is provided at one end of the locking rod 6. The size of the rod cap 7 is larger than that of the fixing hole 5. The rod cap 7 facilitates the insertion and removal of the locking rod 6 when the template is disassembled and assembled; a threaded section is provided at the end of the other end of the locking rod 6, and a nut 8 is provided on the threaded section.

[0022] The fixing hole 5 is a through hole that passes through the plate body 1. The length of the locking rod 6 is greater than the width of the side of the plate body 1 where the plug hole 3 is located. When the locking rod 6 is inserted into the fixing hole 5 and the rod cap 7 contacts the plate body 1, the end of the locking rod 5 opposite to the rod cap 7 protrudes from the plate body 1, and the locking rod 5 and the plate body 1 are fixed together with a nut.

[0023] The plate body 1 is in the shape of a rectangular parallelepiped, and the top of the plate body 1 is used to contact with concrete to ensure that a uniform and precise casting surface can be formed when in contact with concrete. When a flat surface needs to be cast, the connector 2 is set on the right side of the plate body 1, and the plug hole 3 is set on the left side of the plate body 1. By connecting the connectors 2 and the plug holes 4 between these plate bodies 1 in sequence, the plate bodies 1 can be seamlessly spliced ​​to form a flat and continuous casting surface, ensuring a smooth surface after casting. When an outer surface with a corner needs to be cast, the connector 2 is set on the edge of the upper surface of the plate body 1, and an adjacent plate body 1 is vertically connected to the plate body 1. The cooperation of the connector 2 and the plug hole allows the two plate bodies 1 to form a right-angle casting surface.

[0024] like Figure 4As shown, a support is provided on the back of the board body 1, which is convenient for the staff to pick up and carry it. The support includes a cross bar 9 and a plurality of longitudinal bars 10 provided on the back of the board body 1. The cross bar 9 is connected with the longitudinal bars 10 to form a stable support frame. The load-bearing capacity of the board body 1 is enhanced through the reasonable mechanical layout of the cross bar 9 and the longitudinal bars 10.

[0025] The utility model also includes a connecting plate 11 connecting two adjacent plate bodies 1, one end of the connecting plate 11 is connected to the back of one plate body 1, and the other end is connected to the back of the adjacent plate body 1, a threaded hole is provided on the back of the plate body 1, a through hole corresponding to the threaded hole is provided on the connecting plate 11, and bolts 12 are provided in the through hole of the connecting plate 11 and the threaded hole on the back of the plate body 1, and the connecting plate 11 and the plate body 1 are fixed together by the bolts 12, thereby enhancing the stability and reliability of the connection between the two plate bodies 1. There are two connecting plates 11, which are symmetrically arranged on the back of two adjacent plate bodies 1.

[0026] like Figure 5 As shown, the board body 1 is provided with a waterproof layer 13, a reinforcement layer 14, a high temperature resistant layer 15 and a reinforcement layer 16 from the outside to the inside. The waterproof layer 13 can effectively prevent water penetration and protect the internal structure of the board body from being corroded by a humid environment, thereby ensuring its stability and durability. The reinforcement layer 14 enhances the overall strength of the board body, enabling it to withstand greater pressure and external force impact, and provides solid support for the board body 1. The high temperature resistant layer 15 effectively prevents the board body 1 from being deformed or damaged due to high temperature, ensuring its reliability under extreme conditions. The reinforcement layer 16, by adding reinforcement materials, enables the board body 1 to better disperse stress when subjected to external forces, reduce the risk of deformation and rupture, and thus extend its service life.
