In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1 and 2, the cavity wall forming apparatus of the present embodiment includes a lower mold 10, an upper mold 20, a mold net and a support structure 30. Wherein the lower mold 10 is adapted to be placed on a mold table. The upper mold 20 is disposed above the lower mold 10 at intervals, and the upper mold 20 is ring-shaped and encloses a casting space. The template net is arranged in the pouring space. A support structure 30 is provided between the lower die 10 and the upper die 20, the support structure 30 being capable of moving upward and supporting the die net.

By utilizing the technical scheme of the embodiment, when cavity wall production is carried out, the lower die 10 is arranged on a die table, and the reinforcing steel bar meshes are embedded in the space surrounded by the lower die 10 and the A-side concrete is poured. And then the supporting structure 40 is moved upwards, the supporting structure 40 supports the template net, the reinforcing steel bar net sheet is embedded in the casting space enclosed by the upper die 20, the lacing wires are installed, and the B-side concrete is cast on the template net. And finally, conveying the molding device into a curing kiln for curing, and thus, molding the cavity wall can be realized. The cavity wall forming device does not need large-scale overturning equipment when producing the cavity wall, and has lower cost. And the concrete on the A side and the B side can be molded by curing for one time, so that the production efficiency is high. Therefore, the technical scheme of the embodiment solves the defects of high cost and low production efficiency of cavity wall production equipment in the prior art.

As can be seen from fig. 1, the lower mold 10 is used for casting the a-side concrete, and before casting, a reinforcing mesh sheet needs to be laid in the lower mold 10 to install tie bars.

As can be seen from fig. 1, the upper mold 20 is disposed above the lower mold 10 with a space between the upper mold 20 and the lower mold 10 to form a cavity of the cavity wall.

In addition, the upper mold 20 has an annular structure and encloses a casting space, that is, the upper mold 20 encloses the shape of the wallboard. The hollow cavity wall is square in this embodiment, so the upper mold 20 has a square annular structure.

A formwork mesh (not shown) is provided in the casting space formed by the upper mold, and the formwork mesh is used for supporting the B-side concrete. When the B-side casting is performed, the support structure 30 moves upward and supports the formwork mesh from below to support the B-side concrete. In addition, the template net is provided with a plurality of holes, and concrete can drip along the holes so as to form a rough surface structure on the inner side of the B surface, thereby simplifying the process. The rough surface structure can increase the binding force between cast-in-place concrete and precast concrete in the subsequent construction.

As shown in fig. 2, in the technical solution of the present embodiment, the support structure 30 includes a support beam 31, a bolt 32 is provided on the support beam 31, a connection hole 21 is provided on the upper mold 20, the bolt 32 passes through the connection hole 21, an adjusting nut 33 is provided on the bolt 32, and the adjusting nut 33 is located on the upper side of the upper mold 20.

Specifically, the bolts 32 extend in the vertical direction and are provided at end positions of the support beam 31. The bolt 32 passes through the connecting hole 21 from bottom to top, and the adjusting nut 33 is sleeved outside the bolt 32. As will be appreciated by those skilled in the art, when the adjusting nut 33 is screwed, the bolt 32 can move up and down relative to the upper die 20 under the action of the screw thread, thereby driving the support beam 31 up and down relative to the upper die 20.

When the adjusting nut 33 is screwed so that the supporting beam 31 moves upward with respect to the upper die 20, the die net can be supported. When the support beam 31 is not required to support the formwork, the adjusting nut 33 is screwed so that the support beam 31 moves downward with respect to the upper die 20.

Further, the above structure allows the screwing operation for the adjustment nut 33 to be performed on the upper side of the upper die 20, so that the operation space of the adjustment nut 33 is large, facilitating the adjustment.

As shown in fig. 2, in the technical solution of the present embodiment, an embedded nut 211 is provided at the connection hole 21, an adjusting nut 33 is fixedly provided on the bolt 32, and the bolt 32 is rotatably provided with respect to the support beam 31, a fixing member 34 is provided between the bolt 32 and the support beam 31, and the fixing member 34 is adapted to fix the relative positions of the bolt 32 and the support beam 31 in the up-down direction.

Specifically, the insert nut 211 is fixedly provided on the upper surface of the upper mold 20, and the insert nut 211 is coaxially provided with the connection hole 21. Thus, the bolts 32 pass through the coupling holes 21 and then pass through the embedded nuts. The adjusting nut 33 is fixedly arranged on the bolt, so that the bolt 32 can be driven to synchronously rotate by screwing the adjusting nut 33. As the bolt 32 rotates, the threads between the bolt 32 and the pre-buried nut 211 allow the bolt 32 to move up or down relative to the upper mold 20. The bolt 32 is rotatable relative to the supporting beam 31, and the relative positions of the bolt 32 and the supporting beam 31 along the up-down direction are fixed by the fixing piece 34, so that the bolt 32 can drive the supporting beam 31 to synchronously move upwards when moving upwards, and further the supporting effect is achieved.

As shown in fig. 2, in the technical solution of the present embodiment, the bolt 32 penetrates the support beam 31 up and down, and the fixing member 34 is a clamping sleeve or clip provided on the bolt 32, and the fixing member 34 is located at the lower side of the support beam 31. Specifically, when the bolt 32 moves upward, the fixing member 34 supports the support beam 31 from below, and thus the bolt 32 and the support beam 31 move upward in synchronization.

In addition, the clamping sleeve or the clamping clip is detachably arranged, namely, after the A face and the B face of the cavity wall are molded, the clamping sleeve or the clamping clip can be detached, and at the moment, the supporting beam 31 can move downwards and be separated from the bolt 32. Meanwhile, the adjusting nut 33 is screwed so that the bolt 32 is unscrewed from the embedded nut 211 even though there is no interference between the bolt 32 and the support beam 31. After the support beam 31 and the bolts 32 are separated, they can be pulled out from the side and separated from the lower die 10 and the upper die 20, thereby achieving disassembly.

Further, bolts 32 are arranged at two ends of the supporting beam 31, connecting holes 21 are formed in two opposite side edges of the upper die 20, embedded nuts 211 are arranged at each connecting hole 21, and two bolts 32 correspondingly penetrate through the two connecting holes.

In addition, the support beam 31 may be detachably provided by other structures, for example, the support beam 31 is fixedly provided with the bolt 32, that is, the fixing member 34 is not provided. The connecting hole 21 is not provided with a pre-buried nut 211, and the adjusting nut 33 is rotatably provided on the bolt 32. In this embodiment, the adjustment nut 33 directly abuts against the surface of the upper die 20 and supports the support beam 31. When the adjusting nut 33 is screwed so that the adjusting nut 33 is separated from the bolt 32, the bolt 32 can be pulled out downward from the connection hole 21, and the support beam 31 is disassembled.

Further, in this embodiment, in order to ensure that the support beam 31 can be withdrawn from between the lower die 10 and the upper die 20, the sum of the thickness of the support beam 31 and the length of the bolt 32 protruding from the support beam 31 should be smaller than the distance between the lower die 10 and the upper die 20. Specifically, since the support beam 31 and the bolt 32 are fixedly coupled, when the adjusting nut 33 is separated from the bolt 32 and the bolt 32 is downwardly withdrawn from the coupling hole 21, the support beam 31 and the bolt should have a gap with the lower mold 10 and the upper mold 20, thereby ensuring that both can be withdrawn from the side to be disassembled.

Preferably, the support beam 31 is a square steel tube. As can be seen in connection with fig. 2, the upper and lower surfaces of the square steel pipe are provided with connection holes, through which bolts 32 pass through the square steel pipe.

Further, in the embodiment shown in fig. 2, the fixing member 34 is located on the lower surface of the square steel pipe, so that the lower portion of the square steel pipe can be supported by the fixing member 34, and the posture of the square steel pipe can be adjusted, so that the upper surface of the square steel pipe is horizontal, the levelness of the formwork mesh is ensured, and the casting effect is improved.

In addition, it will be appreciated by those skilled in the art that in practice the lifting and lowering of the square steel pipe is achieved by the square steel pipe having a surface which cooperates with the fixing member 34, and thus the fixing member 34 may be provided at the upper surface of the inside of the square steel pipe, which embodiment enables the length of the bolt 32 to be made shorter. Further, the support beam 31 may be a solid structure, and the cross section of the support beam 31 may be provided in various shapes.

As shown in fig. 1 and 3, in the technical solution of the present embodiment, a plurality of support beams 31 are provided, and a plurality of support beams 31 are arranged at intervals. Specifically, the plurality of support beams 31 are uniformly distributed and cover the area surrounded by the upper die 20. Each support beam 31 is vertically adjustable by a bolt 32 and an adjusting nut 33, and each support beam 31 is extractable and removable.

Preferably, the template mesh is a steel mesh or a fast-easy-closing mesh.

As shown in fig. 3, in the technical solution of the present embodiment, a support member 40 is provided between the lower die 10 and the upper die 20. The supporting member 40 is used for supporting the upper die 20 above the lower die 10, and the supporting member 40 has a "table" shape.

Preferably, the upper mold 20 is surrounded by four side plates. Because the blades of the cavity wall have a square structure, the upper mold 20 is surrounded by four side plates to form a square structure.

The embodiment also provides a cavity wall production line, which comprises the cavity wall forming device.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the utility model.
