Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an anti-leakage mould for reserved holes in floor slabs. Background Art

[0002] In the construction of building projects, it is often encountered that holes are reserved on concrete floor slabs. Before pouring concrete on the floor slab, a reserved hole mold is set on the bottom mold of the floor slab. The reserved hole mold is used to hinder the concrete when pouring the floor slab. After the floor slab concrete is solidified, the reserved hole mold is removed, and the reserved hole is formed at the location of the original reserved hole mold.

[0003] The existing reserved hole mold is a conventional cylindrical mold. Although it can form a reserved hole, the reserved hole formed by it is very likely to cause leakage hazards. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a floor reserved hole anti-leakage mold to solve the problem that the reserved hole formed by the reserved hole mold in the prior art is very likely to cause leakage hazards.

[0005] To achieve the above-mentioned purpose, the present invention provides a floor reserved hole anti-leakage mold, comprising a mold body and a fixing assembly for fixing the mold body on the floor bottom mold;

[0006] The mold body comprises a first mold barrel, a connecting ring plate, a second mold barrel and an anti-seepage ring;

[0007] The inner diameter of the first mold cylinder is smaller than the inner diameter of the second mold cylinder;

[0008] The second mold cylinder is coaxially arranged above the first mold cylinder;

[0009] The connecting ring plate connects the top end of the first mold cylinder and the bottom end of the second mold cylinder;

[0010] The anti-seepage ring is connected to the bottom of the second mold cylinder.

[0011] By adopting this technical solution, the reserved hole mold is divided into two parts, a first mold cylinder and a second mold cylinder, which are connected with a connecting ring plate to form a stepped cylindrical structure. On the one hand, the inner area of ​​the reserved hole formed after the cast-in-place concrete floor is solidified is increased to facilitate subsequent sealing. On the other hand, an anti-seepage ring connected to the bottom of the connecting ring plate can form an anti-seepage groove at the corresponding position after the cast-in-place concrete floor is solidified, thereby increasing the anti-seepage effect of the reserved hole after subsequent sealing and coping with the hidden danger of water leakage after the reserved hole is sealed.

[0012] Furthermore, the inner diameter of the first mold barrel increases from bottom to top;

[0013] The inner diameter of the second mold cylinder increases from bottom to top.

[0014] By adopting this technical solution, the first mold barrel and the second mold barrel are both set to have inner diameters that increase from bottom to top, and the overall mold composed of the first mold barrel, the connecting ring plate and the second mold barrel can be dismantled after use, and a reserved hole with a larger top and a smaller bottom can be formed subsequently to facilitate cleaning and sealing.

[0015] Furthermore, the anti-seepage ring is coaxially connected to the bottom of the connecting ring plate with a plurality of;

[0016] Adjacent anti-seepage rings do not contact each other.

[0017] By adopting this technical solution, a number of anti-seepage rings are set up to form support rod anti-seepage grooves after the concrete is solidified, which is beneficial to increase the anti-seepage effect after the reserved hole is sealed; the lack of contact between adjacent anti-seepage rings can ensure that the number of anti-seepage rings is the same as the number of anti-seepage grooves formed subsequently, thereby exerting a high anti-seepage effect.

[0018] Furthermore, the fixing assembly includes wedge-shaped blocks and screws evenly arranged along the inner wall of the first mold barrel;

[0019] The outer side wall of the wedge-shaped block abuts against the inner wall of the first mold cylinder;

[0020] The screw is inserted into the wedge-shaped block from top to bottom.

[0021] By adopting this technical solution, since the inner wall of the first mold cylinder is inclined inward from top to bottom, when the wedge-shaped block is fixed to the cast-in-place concrete floor bottom mold by screws, it can support the first mold cylinder outward by screwing the screws downward, thereby completing the fixation of the entire mold on the cast-in-place concrete floor bottom mold and ensuring that the bottom of the mold fits with the cast-in-place concrete floor bottom mold.

[0022] Furthermore, the wedge-shaped block is a rubber block.

[0023] By adopting this technical solution, the wedge-shaped block has a certain elasticity and can be tightly squeezed against the inner wall of the first mold tube under the action of screws to fix the entire mold on the cast-in-place concrete floor bottom mold, thereby increasing the stability of fixing the entire mold on the cast-in-place concrete floor bottom mold using the wedge-shaped block in combination with the screws.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The first mold cylinder, the connecting ring plate and the second mold cylinder constitute an integrated stepped cylindrical mold. On the one hand, the inner area of ​​the reserved hole formed after the cast-in-place concrete floor is solidified is increased to facilitate subsequent plugging. On the other hand, the anti-seepage ring connected to the bottom of the connecting ring plate can form an anti-seepage groove at the corresponding position after the cast-in-place concrete floor is solidified, thereby increasing the anti-seepage effect of the reserved hole after subsequent plugging and coping with the hidden danger of water leakage after the reserved hole is plugged.

[0026] 2. The first mold cylinder and the second mold cylinder in the mold are both cylindrical structures with increasing inner diameters from bottom to top, which can reduce the difficulty of removing them from the solidified concrete after the concrete is poured and solidified.

[0027] 3. The outer wall of the wedge-shaped block used to fix the mold cooperates with the inclined surface of the inner wall of the mold. The screw can be unscrewed to complete the fixation of the mold on the bottom mold of the cast-in-place concrete floor slab. At the same time, the bottom end surface of the mold is pressed tightly against the top surface of the bottom mold of the cast-in-place concrete floor slab to avoid the problem of concrete entering the mold when pouring concrete.

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Please refer to the attached Figure 1-2 The present invention provides an anti-leakage mold for reserved holes in a floor slab, comprising a mold body 1 and a fixing assembly for fixing the mold body 1 on a floor slab bottom mold; wherein the mold body 1 comprises a first mold barrel 11, a connecting ring plate 13, a second mold barrel 12 and an anti-seepage ring 4; the inner diameter of the first mold barrel 11 is smaller than the inner diameter of the second mold barrel 12; the second mold barrel 12 is coaxially arranged above the first mold barrel 11; the connecting ring plate 13 connects the top end of the first mold barrel 11 and the bottom end of the second mold barrel 12; the anti-seepage ring 4 is connected to the bottom of the second mold barrel 12.

[0035] The reserved hole mold is divided into two parts, a first mold cylinder 11 and a second mold cylinder 12, which are connected with a connecting ring plate 13 to form a stepped cylindrical structure. On the one hand, the inner area of ​​the reserved hole formed after the cast-in-place concrete floor is solidified is increased to facilitate subsequent plugging. On the other hand, the anti-seepage ring 4 connected to the bottom of the connecting ring plate 13 can form an anti-seepage groove at the corresponding position after the cast-in-place concrete floor is solidified, thereby increasing the anti-seepage effect of the reserved hole after subsequent plugging, and coping with the hidden danger of water leakage after the reserved hole is blocked.

[0036] The first mold barrel 11 and the second mold barrel 12 are both set to have inner diameters that increase from bottom to top. The overall mold composed of the first mold barrel 11, the connecting ring plate 13 and the second mold barrel 12 can be dismantled after use, and a reserved hole with a larger top and a smaller bottom can be formed subsequently to facilitate cleaning and sealing.

[0037] Several anti-seepage rings 4 are coaxially connected to the bottom of the connecting ring plate 13; adjacent anti-seepage rings 4 do not contact each other; setting a number of anti-seepage rings 4 corresponding to the support rod anti-seepage groove can be formed after the concrete is solidified, which is beneficial to increase the anti-seepage effect after the reserved hole is sealed; the non-contact between adjacent anti-seepage rings 4 can ensure that the number of anti-seepage rings 4 is the same as the number of anti-seepage grooves formed subsequently, thereby exerting a high anti-seepage effect.

[0038] The fixing assembly includes wedge-shaped blocks 2 and screws 3 evenly distributed along the inner wall of the first mold cylinder 11; the outer wall of the wedge-shaped blocks 2 abuts against the inner wall of the first mold cylinder 11; the screws 3 are passed through the interior of the wedge-shaped blocks 2 from top to bottom; since the inner wall of the first mold cylinder 11 is inclined inward from top to bottom, when the wedge-shaped blocks 2 are fixed to the bottom mold of the cast-in-place concrete floor slab by the screws 3, the first mold cylinder 11 can be supported outward by the downward rotation of the screws 3, thereby completing the fixation of the entire mold on the bottom mold of the cast-in-place concrete floor slab, and ensuring that the bottom of the mold fits with the bottom mold of the cast-in-place concrete floor slab.

[0039] The wedge-shaped block 2 is a rubber block; the wedge-shaped block 2 has a certain elasticity, and can be tightly squeezed with the inner wall of the first mold cylinder 11 under the action of the screw 3 to fix the entire mold on the cast-in-place concrete floor bottom mold, thereby increasing the stability of fixing the entire mold on the cast-in-place concrete floor bottom mold using the wedge-shaped block 2 in combination with the screw 3.

[0040] For further information, see Figure 3 The mold body 1 can be a cylindrical mold, and accordingly, the first mold cylinder 11 and the second mold cylinder 12 are both cylindrical, and the connecting ring plate 13 and the anti-seepage ring 4 are both annular.

[0041] For further information, see Figure 4 The mold body 1 can be a square cylinder mold, and accordingly, the first mold cylinder 11 and the second mold cylinder 12 are both square cylinders, and the connecting ring plate 13 and the anti-seepage ring 4 are both square rings.
