[0002] In the process of building construction, the wall will inevitably be left with a hole during the process of connecting the scaffold connecting wall piece and the cantilever I-beam outer frame erection, and the hole left on the wall needs to be plugged later. The common plugging method is the hole pouring construction method disclosed in patent No. CN118704465A, which pours the hole concrete from the inside to the outside in the secondary formwork, but this method not only has a long construction period, but also the top of the hole is not easy to be filled with concrete, resulting in a gap at the connection position of the hole concrete and the wall concrete, and the problem of rainwater seepage from the inside is prone to occur later. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at solving the problem of rainwater seepage from the inside at the connection position of the hole concrete and the wall concrete, thereby providing a hole mold capable of effectively plugging the hole and avoiding rainwater seepage from the inside.

[0004] The utility model solves the problem by adopting the technical scheme of:

[0005] A wall reserved hole mold, the hole mold is used for being arranged in a wall mold to set a reserved hole position and for pouring a prefabricated block, the width of the hole mold is the same as the width of the wall mold, and the two ends of the hole mold are respectively abutted with the inner wall and the outer wall of the wall mold.

[0006] Compared with the prior art, the utility model has the beneficial effects of:

[0007] The utility model designs the hole mold, installs the hole mold at the set wall hole position when the wall mold is erected, divides the hole position and the wall concrete through the hole mold when the wall is poured, thereby reserving the hole on the wall, takes out the hole mold after the wall concrete is solidified, utilizes the hole to connect the scaffold connecting wall piece or the cantilever I-beam outer frame to perform construction, inserts the prefabricated block into the hole after the construction is completed, and the hole position is filled, the prefabricated block is poured by the hole mold, is the same as the size and shape of the hole mold, can fill the hole, makes the gap between the prefabricated block and the wall concrete as small as possible, and can greatly avoid rainwater from seeping from the connecting gap to the inside of the wall.

[0008] As a preferred embodiment, the utility model further has the technical scheme of:

[0009] The hole opening mold comprises a top plate, a bottom plate, and left and right side plates, the top plate and the bottom plate are fixed with the left and right side plates by bolts respectively, and when the hole opening mold is arranged at the reserved hole opening position of the wall mold, the horizontal projection of the length direction of the two side plates is the same as the width of the wall mold. The hole opening mold is assembled by the top plate, the bottom plate, and the two side plates to isolate the hole opening position in the wall mold.

[0010] When the hole opening mold is arranged at the reserved hole opening position of the wall mold, the outer end of the top plate and the bottom plate of the hole opening mold is lower than the inner end. Through the above structure, when the hole opening mold is installed in the wall mold, the outer end of the top plate and the bottom plate is inclined downward, which can effectively avoid the rainwater outside the wall from seeping inward through the connecting gap, and the water in the wall above the hole opening position will also flow to the outside of the wall due to the self-weight from the inclined surface of the top plate; thereby greatly reducing the possibility of seepage on the inside of the wall.

[0011] The left and right sides of the top plate and the bottom plate are provided with bending parts, each bending part is attached to the adjacent side plate, and the bending part and the attached side plate are fixed by bolts. The top plate, the bottom plate, and the two side plates are fixed and connected by bolts through the setting of the bending parts.

Specifically, when the hole mold is set at the reserved hole position of the wall mold 6, the horizontal projection of the length direction of the two side plates is the same as the width of the wall mold 6, so that the inner end and the outer end of the two side plates of the hole mold abut against the inner and outer walls of the wall mold 6. The hole mold is assembled by the top plate 1, the bottom plate 3 and the two side plates to isolate the hole position in the wall mold 6. The hole mold is also used for pouring the precast block 9. Specifically, when the hole mold is used for pouring the precast block 9, the outer side of the hole mold is placed on a plane as the bottom of the pouring space.

[0021] In the embodiment, the top plate 1, the bottom plate 3, the left side plate 2 and the right side plate 4 are all made of 6mm steel plates. The left and right sides of the left side plate 2 are parallel to each other. The top surface and the bottom surface of the left side plate 2 are both inclined surfaces with the same inclination direction. Preferably, the inclination angle of the top surface is set to 20°-30°, and the inclination angle of the bottom surface is set to 5°-10°. The right side plate 4 has the same size as the left side plate 2. When the hole mold is set at the reserved hole position of the wall mold 6, the outer diameter of the hole mold is smaller than the inner diameter, and the outer end of the top plate 1 and the bottom plate 3 of the hole mold is lower than the inner end. Through the above structure, when the hole mold is installed in the wall mold 6, the top plate 1 and the bottom plate 3 are both inclined surfaces with the outer end downward, which can effectively prevent the rainwater on the outside of the wall from seeping to the inside of the wall through the connecting gap, and the water in the wall above the hole position will also flow to the outside of the wall from the top plate 1 due to gravity, thereby greatly reducing the possibility of seepage on the inside of the wall.

[0022] In the embodiment, the left and right sides of the top plate 1 are integrally formed with bending parts bent downward by 20mm.
