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 formwork for pouring supporting columns in a basement of a house, including a formwork body 1 and a steel strip 2, the steel strip 2 includes two hinged semicircular steel rings 3, and a connecting block 4 is provided on the outside of the free end of one of the steel rings 3, The connecting block 4 is provided with a threaded hole 5, and the threaded hole 5 is screwed with a fixing bolt 6; the outer side of the free end of the other steel ring 3 is welded with a bump 7, and the bump 7 is provided with a mounting hole 8, and the inside of the mounting hole 8 A nut 9 is provided, and the nut 9 is interference fit with the mounting hole 8. Cover plates 10 are provided at both ends of the projection 7, and each cover plate 10 is connected with the projection 7 by four bolts. Both cover plates 10 are A through hole 11 is provided, and the diameter of the through hole 11 is smaller than the diameter of the mounting hole 8 and lar...

Embodiment 2

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

[0041] On the basis of Embodiment 1, the housing basement support column 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 an opening 16 is provided on the inner ring 13; 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 adjustment ring 12 The height is less than the height of the steel 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 constr...

Embodiment 3

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

[0049] This embodiment provides a construction method for pouring support columns in a basement of a house, using the formwork for pouring support 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 support column.

[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 ...

Abstract

The invention provides a house basement support pillar pouring template and a construction method and belongs to the technical field of house building. The template comprises a template body and a steel belt, wherein the steel belt comprises two semi-circular steel rings hinged with each other, a connecting block is welded at the outer side of the free end of one of the steel rings, a threaded hole is formed in the connecting block, a fixed bolt is screwed into the threaded hole; and a lug is welded at the outer side of the free end of the other steel ring, a mounting hole is formed in the lug, a nut is arranged in the mounting hole, the nut is in interference fit with the mounting hole, cover plates are arranged at two ends of the lug, and each cover plate is connected with the lug by four bolts. By adopting the template and the method, the steel belt can be pre-tightened quickly, so that the construction efficiency is improved, occurrence of template blast is effectively prevented, and potential safety hazard can be reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a formwork for pouring supporting columns in a basement of a building and a construction method. Background technique [0002] In the process of house construction, many places need to use support columns for support, such as halls and basements. When building support columns for a house, the following steps are generally followed: [0003] Erection of steel bars in support columns; [0004] Set the pouring formwork for the supporting columns 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, a...
