[0030] Embodiment

[0031] As Figure 1 shown, a concrete box module includes a first wall formwork and a steel reinforcement cage 4. The first wall formwork is arranged in the vertical direction and is used as the wall formwork of the shear wall. The steel reinforcement cage 4 extends in the vertical direction, and the steel reinforcement cage 4 is installed on the outer side of the first wall formwork and is connected to the first wall formwork.

[0032] In the present utility model, by installing the steel reinforcement cage 4 on the outer side of the wall formwork of the shear wall, the integration degree of the concrete box module is increased. During construction, it is no longer necessary to bind the steel reinforcement cage 4 on site, reducing the on-site construction procedures, accelerating the construction progress, and improving the construction efficiency.

[0033] During the installation construction process, an outer formwork is further installed on the outer side of the steel reinforcement cage 4. The outer formwork and the first wall formwork enclose a pouring cavity, and concrete is poured into the pouring cavity to form a shear wall. Among them, the outer formwork can be a formwork for concrete pouring or a metal formwork, such as a steel formwork or an aluminum formwork.

[0034] As Figure 1As shown in the figure, the concrete box module further includes a bottom plate 2 arranged horizontally, a composite top plate 1 arranged horizontally, and a plurality of second wall forms 3 extending vertically. The composite top plate 1 is placed above the bottom plate 2. The first wall form and the plurality of second wall forms 3 are placed between the bottom plate 2 and the composite top plate 1 and are arranged along the periphery of the bottom plate 1. The bottom plate 2, the composite top plate 1, the first wall form, and the plurality of second wall forms 3 enclose a concrete box module in the shape of a cuboid or a cube. The thickness of the second wall form 3 is greater than that of the first wall form. In this embodiment, the thickness of the first wall form is 20 mm to 40 mm, and the thickness of the second wall form is 60 mm to 230 mm.

[0035] Specifically, as Figure 1 shown, in this embodiment, there are four second wall forms 3, namely a rear wall form located at the rear side of the bottom plate 1 and parallel to the rear side surface of the bottom plate 1, a right wall form located at the right side part of the bottom plate 1 and parallel to the right side surface of the bottom plate 1, a front wall form located at the front side part of the bottom plate 1 and parallel to the front side surface of the bottom plate 1, and a left wall form located at the left side part of the bottom plate 1 and parallel to the left side surface of the bottom plate 1. The first wall form is installed at the front side part of the bottom plate 1. Among them, the length of the rear wall form is the same as that of the rear side surface of the bottom plate 1, the length of the right wall form is the same as that of the right side surface of the bottom plate 1, the sum of the lengths of the front wall form and the first wall form is the same as that of the front side surface of the bottom plate 1, and the length of the left wall form is less than that of the left side surface of the bottom plate 1. A door opening is also provided on the left side surface of the concrete box module, and the sum of the length of the door opening and the left wall form is the same as that of the left side surface of the bottom plate 1.

[0036] A plurality of truss bars extending in the front - rear direction are provided at the top end of the composite top plate 1, and the plurality of truss bars are evenly spaced in the left - right direction to increase the strength of the composite floor slab 1 through the truss bars.

[0037] As Figure 1 shown, the cross - sectional shape of the first wall form is a straight shape, an L - shape, or a U - shape. In order to enable the steel reinforcement cage 4 to increase the strength of the shear wall formed by the entire first wall form, the structural shape of the steel reinforcement cage 4 is the same as that of the first wall form. Therefore, the cross - section of the steel reinforcement cage 4 is also a straight shape, an L - shape, or a U - shape.

[0038] As Figure 2 shown, the steel reinforcement cage 4 includes a plurality of first vertical steel bars 41 extending vertically, a plurality of second vertical steel bars extending vertically, a plurality of first horizontal steel bars arranged horizontally, a plurality of second horizontal steel bars 42 arranged horizontally, and a plurality of connecting bars. The first vertical steel bars 41 and the second vertical steel bars are arranged in parallel at intervals. The first horizontal steel bars are placed outside the first vertical steel bars, and the second horizontal steel bars 42 are placed outside the second vertical steel bars. The connecting bars extend in a direction perpendicular to the first wall form, and one end of the connecting bar extends into the first wall form. The first vertical steel bars 41, the first horizontal steel bars, the second vertical steel bars, and the second horizontal steel bars 42 are all connected to the connecting bars.

[0039] As shown Figure 1 in the figure, the steel reinforcement cage 4 further includes a first edge member and a second edge member. Both the first edge member and the second edge member are installed between the first vertical steel bar and the second vertical steel bar, and the first edge member is located at one end of the first horizontal steel bar, while the second edge member is located at the other end of the horizontal steel bar. Through the first edge member and the second edge member, the strength of the steel reinforcement cage 4 is increased, thereby enhancing the strength of the shear wall after pouring.

[0040] Specifically, the first edge member is in a straight shape, and the second edge member has the same structure as the first wall form. In this embodiment, the second edge member takes an L-shaped structure as an example. The first edge member includes a plurality of third vertical steel bars and a plurality of first stirrups 45. The plurality of third vertical steel bars enclose a rectangular structure, and the first stirrups 45 are sleeved on the plurality of third vertical steel bars and are connected to the third vertical steel bars.
