Problems solved by technology

The existing steel belt is basically a clamp structure, and the whole is relatively simple. When the steel belt is used to pre-tighten the formwork, the pre-tightening force is not easy to grasp, and it takes a long time of construction experience to roughly grasp it.
In practice, too tight or too loose preload is not good for concrete pouring, and the construction difficulty of steel strip fixing makes it difficult for construction workers with less experience to quickly find a suitable preload during construction, which is not conducive to concrete pouring. Smooth pouring of concrete

Embodiment 1

[0031] Example 1, see Figure 1-Figure 5

[0032] A cylindrical pouring formwork for the basement of a house, comprising a formwork body 1 and a steel belt 2, the steel belt 2 includes two hinged semicircular steel rings 3, and a connecting block 4 is provided on the outside of the free end of one steel ring 3 to connect The block 4 is provided with a threaded hole 5, and the threaded hole 5 is screwed with a fixing bolt 6; the outside of the free end of the other steel ring 3 is provided with a projection 7, and the projection 7 is provided with a mounting hole 8, and the mounting hole 8 is provided with a There are nuts 9, the nuts 9 are interference fit with the mounting holes 8, the two ends of the bump 7 are provided with cover plates 10, the cover plates 10 are connected with the bumps 7 through bolts, and through holes 11 are provided on the two cover plates 10, The diameter of the through hole 11 is smaller than the diameter of the mounting hole 8 and larger than the ...

Embodiment 2

[0040] Example 2, see Figure 1-Figure 6

[0041] On the basis of Embodiment 1, the house basement cylindrical pouring formwork provided by this embodiment also includes an adjustment ring 12, and the adjustment ring 12 includes a coaxial inner ring 13 and an outer ring 14, and the inner ring 13 and the outer ring 14 are arranged at intervals. A plurality of elastic steel sheets 15 are connected, and the inner ring 13 is provided with an opening 16; the outer diameter of the outer ring 14 is consistent with the outer diameter of the template body 1, the inner diameter of the inner ring 13 is consistent with the inner diameter of the template body 1, and the height of the adjustment ring 12 less than the height of the strip 2.

[0042] During the construction process of the house, many places need to use formwork and then pour concrete, which may lead to mold explosion in some cases, such as high outside temperature, uneven mixing of concrete, and errors in the construction se...

Embodiment 3

[0048] Example 3, see Figure 1-Figure 8

[0049] This embodiment provides a construction method for pouring columns in a basement of a house, using the formwork for pouring columns in a basement of a house in Embodiment 2. The construction method includes the steps of:

[0050] A plurality of formwork bodies 1 are stacked vertically. The number of formwork bodies 1 is selected according to the height of the cylinder.

[0051] Steel strips 2 are fixed on the outer sides of every two adjacent formwork bodies 1 . The fixing of the steel strip 2 is carried out synchronously with the stacking of the formwork body 1 . The steel belt 2 can not only be fixed on the outer sides of every two adjacent formwork bodies 1, but also can be fixed at other positions, so that the reinforcement effect on the formwork body 1 is better. When the above-mentioned steel belt 2 is used for reinforcement, the reinforcement work can be carried out quickly, the safety of each part can be protected,...

Abstract

The invention provides a house basement cylinder pouring formwork and a construction method and belongs to the technical field of house building. The formwork comprises a formwork body and a steel belt, the steel belt comprises two semicircular steel rings which are hinged, a connecting block is welded on the outer side of a free end of one of the steel rings, a threaded hole is formed in the connecting block, a fixing bolt is connected on the threaded hole in a threaded manner, a convex block is arranged on the outer side of a free end of the other steel ring, a mounting hole is formed in the convex block, a nut is arranged in the mounting hole and is in interference fit with the same, and cover plates are arranged at two ends of the convex block and connected with the convex block through bolts. By the formwork and the construction method, the steel belt can be pretightened quickly, so that construction efficiency is improved; formwork explosion is prevented effectively, and potential safety hazards are lowered.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a cylindrical pouring formwork for a basement of a house and a construction method. Background technique [0002] In the process of house construction, columns need to be used for support in many places, such as halls and basements. When building a house column, the following steps are generally followed: [0003] Erection of steel bars inside the cylinder; [0004] Set the pouring formwork of the column outside the reinforcement; [0005] to pour concrete; [0006] demoulding. [0007] The pouring formwork is basically made of wood. When the pouring formwork is fixed, it needs to be fixed externally by steel strips. The existing steel belt is basically a clamp structure, and the overall structure is relatively simple. When the steel belt is used to pre-tighten the formwork, the pre-tightening force is not easy to grasp, and it takes a long time of construction...
