Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a wire-laying hole mould. Background Art

[0002] In traditional construction, the wire hole mold is generally made of wood glue board nailed together, which is easy to damage and deform, has a limited number of turnover uses, has poor hole-making effect, and is troublesome to seal later. Utility Model Content

[0003] The utility model aims to provide a wire-laying hole mould.

[0004] The utility model is realized by the following measures: a wire-laying hole mold, characterized in that it comprises a stepped body with a larger upper part and a smaller lower part formed by a hollow upper mold and a lower mold;

[0005] The upper mold comprises an upper part and a lower part, and the upper part and the lower part are detachably connected; generally, bolts are used for connection, and ear plates for mounting bolts are fixedly provided on the inner walls of the upper part and the lower part;

[0006] A blocking plate is fixedly arranged at the inner lower part of the lower mold;

[0007] The upper end surface of the blocking plate is higher than the lower end surface of the floor slab, and the upper end surface of the lower portion is lower than the upper end surface of the floor slab.

[0008] The upper end and the lower end of the upper die, and the upper end and the lower end of the lower die are all concentrically arranged and gradually approach the middle from top to bottom. The cross-sectional shapes of the upper die and the lower die are both rectangular or circular.

[0009] The cross-sectional shapes of the upper die and the lower die are both square.

[0010] It also includes cross-shaped supporting ribs overlapped on the lower part and the inner wall of the lower mold.

[0011] The upper end of the upper mold exposes the upper end surface of the floor slab, which is convenient for later demoulding; the lower end of the lower mold exposes the lower end surface of the floor slab.

[0012] The upper end surface of the lower part is lower than the upper end surface of the floor slab.

[0013] Working principle:

[0014] Drill a hole on the top template and place the layout hole mold. Brush the release agent on the outside of the layout hole mold for easy removal. After the concrete floor slab hardens, remove the layout hole mold and the layout hole is completed.

[0015] After the wire release hole is fabricated, remove the upper part and pour the blocking block. Before pouring, apply a release agent to the lower part and the inner surface of the lower mold. Place a cross-shaped support bar inside the lower mold and the lower part. The end of the cross-shaped support bar directly overlaps on the inclined side walls of the lower mold and the lower part. The cross-shaped support bar can enhance the strength of the blocking block. Then pour concrete with the same grade as the floor slab into the mold. After the concrete solidifies, take out the formed concrete block, and the blocking block is fabricated.

[0016] When the wire release hole needs to be blocked, first clean the hole, moisten the surface with water, and evenly apply high-strength cement mortar around and at the steps (place an appropriate amount of mortar at the steps to ensure that the bottom of the blocking block is flush with the bottom of the floor slab). Put the fabricated blocking block into the wire release hole to block the hole. Finally, lay a piece of wire mesh and use high-strength cement mortar to plaster the upper and lower surfaces of the blocking block until they are flush with the end face of the floor slab. At this time, the blocking of the wire release hole is completed.

[0017] The beneficial effects brought by the technical solution provided in the embodiment of the present utility model are as follows: The wire release hole mold is made of welded steel plates, which is not easy to deform, has a good forming effect, can be reused, and after the mold is used up, it can be used as a mold for the wire release hole blocking block to fabricate the wire release hole blocking block, realizing the rapid blocking of the wire release hole, saving time and effort, and effectively improving work efficiency.

[0025] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with embodiments. Of course, the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] See Figures 1 - 5 , a wire-releasing hole mold, which is characterized in that it includes a stepped body with a large upper part and a small lower part formed by a hollow upper die 1 and a lower die 2.

[0027] The upper die 1 includes an upper part 101 and a lower part 102, and the upper part 101 and the lower part 102 are detachably connected; generally, bolts are used for connection, and ear plates 103 for installing bolts are fixedly arranged on the inner walls of the upper part 101 and the lower part 102.

[0028] A sealing plate 3 is fixedly arranged at the lower part 102 inside the lower die 2.

[0029] The upper end face of the sealing plate 3 is higher than the lower end face of the floor slab 6, and the upper end face of the lower part 102 is lower than the upper end face of the floor slab 6.

[0030] The upper end and the lower end of the upper die 1, and the upper end and the lower end of the lower die 2 are concentrically arranged and gradually move closer to the middle from top to bottom. The cross-sectional shapes of the upper die 1 and the lower die 2 are both rectangular or circular.

[0031] The cross-sectional shapes of the upper die 1 and the lower die 2 are both square.

[0032] It also includes a cross-shaped support rib 4 lapped on the inner walls of the lower part 102 and the lower die 2.

[0033] The upper end of the upper die 1 exposes the upper end face of the floor slab 6, which is convenient for later form removal; the lower end of the lower die 2 exposes the lower end face of the floor slab 6.

[0034] The upper end face of the lower part 102 is lower than the upper end face of the floor slab 6.

[0035] Among them, the lower die 2, the upper part 101 and the lower part 102 of the upper die 1 are welded by steel plates with a thickness of 4-8 mm, generally 6 mm. The top side length of the upper die 1 is generally 220 mm, the bottom side length is generally 170 mm, the height of the upper die 1 is generally 200 mm, the upper part 101 side length of the lower die 2 is generally 130 mm, the bottom side length is generally 100 mm, and the height of the lower die 2 is generally 70 mm. The specific dimensions are generally determined according to the actual situation, and the dimensions in this embodiment are for illustrative purposes.

[0036] Working principle:

[0037] Open holes on the top template, place the wire-releasing hole mold, and apply release agent on the outer side of the wire-releasing hole mold for easy removal. After the concrete floor slab 6 hardens, remove the wire-releasing hole mold, and the wire-releasing hole is then fabricated.

[0038] After the wire-releasing hole is fabricated, remove the upper part 101 and pour the blocking block 5. Apply release agent inside the lower part 102 and the lower mold 2 before pouring. Place the cross-shaped support bars 4 inside the lower mold 2 and the lower part 102. The ends of the cross-shaped support bars 4 are directly lapped on the inclined side walls of the lower mold 2 and the lower part 102. The strength of the blocking block 5 can be enhanced by the cross-shaped support bars 4. Then pour concrete with the same grade as the floor slab 6 into the mold. After the concrete solidifies, take out the formed concrete block, and the blocking block 5 is then fabricated.

[0039] When the wire-releasing hole needs to be blocked, first clean the hole, moisten the surface with water, evenly apply high-strength cement mortar around and at the steps (place an appropriate amount of mortar at the steps to ensure that the bottom of the blocking block 5 is flush with the bottom of the floor slab 6), and put the fabricated blocking block 5 into the wire-releasing hole to block the wire-releasing hole. Finally, arrange a piece of wire mesh cloth, and use high-strength cement mortar to plaster the upper and lower surfaces of the blocking block 5 to be flush with the end face of the floor slab 6. At this time, the blocking of the wire-releasing hole is completed.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
