Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a plugging mold for reserved holes and a construction method for plugging holes by using the same. Background Art

[0002] During the building construction process, a large number of holes need to be reserved, such as measurement and setting-out holes, concrete pouring pump pipe holes, etc., mainly the holes left after the attachment supports of construction equipment are removed, and the positions, sizes and shapes of the holes are different. However, the sizes of existing hole plugging devices are unified, and they cannot cope with the situation of different sizes of reserved holes on the construction site, increasing the difficulty of subsequent hole plugging construction.

[0003] During the actual construction process, usually PVC pipes are embedded when tying steel bars as reserved holes. After the concrete structure is poured and reaches the designed strength requirements, the PVC pipes are manually removed first, the holes are chiseled into a tapered shape with the upper part larger than the lower part, then formwork is supported and jacked back under the holes, and the inner cavities of the holes are plugged with grouting material. This plugging method is inefficient, wastes materials, and the plugging structure is prone to quality defects such as leakage and cracking. Summary of the Invention

[0004] Aiming at the problems of low efficiency, material waste and easy generation of quality defects in the existing construction hole plugging method. The purpose of the present invention is to provide a plugging mold for reserved holes and a construction method for plugging holes by using the same.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a plugging mold for reserved holes, which includes: a tapered mold, a top plate and a handle. The end with a gradually increasing diameter of the tapered mold is detachably connected to the bottom of the top plate, the handle is fixedly connected to the top of the top plate, and the height of the tapered mold is equal to the thickness of the concrete structure to be poured.

[0006] The plugging mold for reserved holes of the present invention includes a top plate, a tapered mold with the end with a gradually increasing diameter detachably connected to the bottom of the top plate, and a handle connected to the top of the top plate; before the concrete is poured, the plugging mold for reserved holes is placed at the designed position of the reserved hole, and after the concrete is poured, the plugging mold for reserved holes is removed to form a frustum-shaped reserved hole with the upper part wider than the lower part; the plugging mold is used in cooperation with the concrete in-situ construction, so that the reserved hole can be formed in one pour with the concrete structure, avoiding the quality defects caused by the method of manually removing the hole and plugging, improving the hole plugging efficiency and plugging quality; the connection between the tapered mold and the top plate is detachable, which is convenient for construction personnel to match the corresponding tapered mold according to the different specifications of the construction holes, so as to meet the construction requirements of various reserved holes; the plugging mold for reserved holes is convenient to disassemble and assemble and can be reused, further reducing the construction cost.

[0007] Further, a bolt is provided at the top of the conical mold, and a matching bolt hole is provided on the top plate, so that the conical mold can be threadedly connected to the top plate.

[0008] Further, the bolt and the bolt hole are arranged along the axis of the conical mold and the top plate.

[0009] Further, it further includes a plugging block. The plugging block is frustum-shaped and matches the shape of the conical mold. The plugging block is installed at the bottom of the reserved hole.

[0010] In addition, the present invention also provides a construction method for plugging holes using the reserved hole plugging mold described above. The steps are as follows:

[0011] Drill a placement hole in the bottom formwork of the concrete structure to be poured. The diameter of the placement hole matches the bottom diameter of the conical mold. Place the conical mold of the reserved hole plugging mold in the formwork, and the bottom surface of the conical mold corresponds to the position of the placement hole. Pour concrete into the formwork at one time. After the concrete structure reaches the designed strength, remove the reserved hole plugging mold to form a reserved hole.

[0012] Place a plugging block at the bottom of the reserved hole so that the plugging block is flush with the bottom surface of the already poured concrete structure. Pour concrete at the top of the reserved hole to make it flush with the top surface of the already poured concrete structure.

[0013] For the construction method of the present invention for plugging holes using the reserved hole plugging mold, first, drill a placement hole in the bottom formwork of the concrete structure to be poured. Place the conical mold in the formwork and make it correspond to the position of the placement hole. After the concrete is poured at one time and reaches the designed strength, remove the reserved hole plugging mold to form a frustum-shaped reserved hole. Place a plugging block at the bottom of the reserved hole and pour concrete at the top of the reserved hole so that the top surface of the plugging structure is flush with the top surface of the already poured concrete structure. Using the plugging mold in combination with the in-situ concrete construction enables the reserved hole to be formed in one pour with the concrete structure without the need for mechanical reaming, avoiding the quality defects caused by the method of manually removing the hole channel and plugging, improving the hole plugging efficiency and plugging quality. This construction method has simple and fast construction procedures, effectively solving the problems of insufficient filling density, complex and time-consuming procedures, and short service life of the plugging structure in the traditional plugging method.

[0014] Further, the step further includes applying a release agent on the outer surface of the conical mold before placing the conical mold of the reserved hole plugging mold in the formwork. Description of the Drawings

[0026] As Figure 1 shown, a bolt 8 is provided at the top of the conical mold 3, and the top plate 2 is provided with a matching bolt 8 hole 4, so that the conical mold 3 can be threadedly connected to the top plate 2, which is convenient for disassembly and assembly, and is convenient for construction personnel to flexibly adjust the corresponding conical mold 3 according to the size of the reserved hole required at the construction site. More preferably, the bolt 8 and the bolt 8 hole 4 are arranged along the axes of the conical mold 3 and the top plate 2, so that the overall force of the plugging mold is more balanced.

[0027] The reserved hole plugging mold of the present invention further includes a plugging block 5. The plugging block 5 is frustum-shaped and matches the shape of the conical mold 3. The plugging block 5 is installed at the bottom of the reserved hole for plugging the placement hole of the bottom formwork, which is convenient for subsequent concrete plugging construction of the reserved hole.

[0028] Combined with Figures 1 to 6 the description of the construction method for plugging holes using the reserved hole plugging mold of the present invention, the specific steps are as follows:
