The spacers 211 may also be a plurality of short rods and are sequentially distributed along a direction parallel to the sideform 102, so as to support the steel mesh at the key supporting point. The spacer 211 includes, but is not limited to, a cement block, a concrete block, or a plastic block. The concrete block is a mixture of cement and stones. The distance between the reinforcing mesh and the die table 101 can be raised by the cushion block 211, so that the reinforcing mesh is positioned in the middle of the page plate in the process of pouring the page plate, and the mechanical property of the page plate is improved. On the premise of properly reducing the performance of the leaf plate, the reinforcing mesh can be properly moved downwards without using the cushion block 211. In other embodiments, the reinforcing mesh is fixed on the side formwork 102 or other structures by arranging proper support legs on the reinforcing mesh, so as to achieve the technical effect that the reinforcing mesh is positioned in the middle of the poured page plate.
Referring to fig. 2, a first steel mesh, wall connecting steel bars 203 and third transverse bars 202 are disposed in a space defined by the mold table 101 and the sideforms 102. The first reinforcing mesh is fixedly connected with the wall connecting reinforcing steel bars 203, and the third transverse ribs 202 are arranged at intervals of a certain distance from the first reinforcing mesh and fixedly connected with the wall connecting reinforcing steel bars 203.
Specifically, first, the first transverse bar 201 of the first mesh is placed on the die table 101. The first transverse ribs 201 are uniformly distributed at intervals and are supported by the cushion block 211.

Meanwhile, in order to avoid interference between the wall connecting steel bars 203 and the cushion block 211 and ensure that the first steel bar net piece at the cushion block 211 has stronger rigidity, the cushion block 211 is supported at the lower part of the first longitudinal bar 204 or the first transverse bar.
The mode of utilizing third horizontal muscle 202, wall connection reinforcing bar 203, first vertical muscle 204, first horizontal muscle 201 to make the steel reinforcement cage can save transportation space and storage space effectively at the scene. However, the integral module formed by the third transverse bar 202 and the wall connecting reinforcing steel bars 203 has a certain gravity, the wall connecting reinforcing steel bars 203 cannot be guaranteed to be vertical, and the manufacturing of the reinforcement cage on the site of manufacturing the cavity wall 200 has a certain operation difficulty and manufacturing quality which is difficult to control. In a preferred scheme, the ladder bar is prepared, and the ladder bar is a bar body which is formed into a ladder shape by connecting a plurality of connecting bars between two longer transverse bars.

In this embodiment, it can be ensured that the sub-module has a high degree of flatness during the manufacturing process. In order to avoid leakage of the cast concrete from the edges of the sub-modules into the space below, the gaps between the sub-modules should be minimized. In a preferred scheme, notches which just avoid the wall connecting steel bars 203 are formed at four corners of the sub-modules, so that the adjacent sub-modules can be well spliced.
Further, a second steel mesh is erected. And the second steel mesh is fixedly connected with the top of the wall connecting steel bar 203.
