It is necessary to strictly control the concrete construction and take special insulation and maintenance measures to avoid concrete cracks. The reinforcement system of the formwork is also particularly important. During the concrete pouring vibration process, it is necessary to control and avoid the phenomenon of formwork expansion or even bursting.

[0003] The traditional wall reinforcement method uses formwork + secondary square wood (or small square steel) + main double steel pipe (or double steel) + steel pipe bracing. The wall insulation of radiation-proof concrete often needs to be covered with a quilt, but this type of reinforcement system is difficult to cover and is not covered in place, which poses a major quality risk and maintenance cost.

The plurality of standard plates are fixed by latches, and also include horizontal reinforcement rods and X-shaped screws, wherein the X-shaped screws are horizontal tensioning screws, and the standard plates on both sides of the wall are tightened and fixed in a tensioning mode, and the horizontal reinforcement rods and the X-shaped screws are fixedly connected to fix the X-shaped screws.

[0005] Preferably, the grille frame includes a frame steel plate, a web and an intermediate rib plate, the web plate is used to fix the mirror template and the inlaid insulation board, the frame steel plate and the intermediate rib plate are fixedly connected to form the overall frame of the grille frame, and the frames are fixed by bolts.

[0006] Preferably, nail holes are provided on the web, and the nail holes are used for firmly fixing the mirror template and the web.

[0007] Preferably, the X-shaped screw is made of 18# screw by bending and welding, the distances between the screw ends are of equal length, and the connection is fixed by a gasket and a double nut.

[0008] Preferably, an oblique support rod is further provided on the outer side of the standard plate, one end of the oblique support rod is fixedly connected to the standard plate, and the other end of the oblique support rod is fixedly connected to the ground.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the standard plate of the utility model is used as a template, as a secondary rib, and takes into account the role of thermal insulation, which optimizes the secondary rib in conventional wall reinforcement and can meet the dual functions of reinforcement and thermal insulation; it reduces the risk of concrete cracks caused by conventional quilts being difficult to cover and inadequately maintained as thermal insulation materials. The risk of radiation vertically passing through the gap between the screw and the concrete is reduced by using X-shaped or double X-shaped standardized tension bolts. According to the thickness of the radiation-proof wall, two groups of the reinforcement system are set at the same time: the standard plate is assembled by staggered pins, and the X-shaped tension bolts are used to connect the horizontal reinforcement rods; the gasket + double nut tension is tightened, and finally the diagonal bracing rods are added to ensure the stability of the wall reinforcement system.
