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 a house, comprising a formwork body 1 and a steel belt 2, the steel belt 2 includes two hinged semicircular steel rings 3, a connecting block 4 is provided on the outside of the free end of one of the steel rings 3, and the connecting block 4 is provided with a threaded hole 5, and the threaded hole 5 is screwed with a fixed bolt 6; the outer side of the free end of the other steel ring 3 is provided with a bump 7, and the bump 7 is provided with a mounting hole 8, and the mounting hole 8 is provided with a Nut 9, nut 9 and mounting hole 8 interference fit, the two ends of projection 7 are provided with the cover plate 10 that is detachably connected with it, two cover plates 10 are all provided with through hole 11, and the diameter of through hole 11 is smaller than installation The diameter of the hole 8 is greater than the diameter of the threaded hole on the nut 9 .

[0033] The templat...

Embodiment 2

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

[0041] On the basis of Embodiment 1, the house 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. Two 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 is less than The height of steel belt 2.

[0042] During the house construction process, 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 concrete mixing, and errors in the construction sequence. A mold explosion ...

Embodiment 3

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

[0049] This embodiment provides a construction method for pouring house cylinders, using the formwork for pouring house cylinders 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, and the construction efficiency i...

Abstract

The invention provides a house cylindrical pouring formwork and a construction method and belongs to the technical field of house building. The formwork comprises a formwork body and a steel band, the steel band comprises two semicircular steel rings which are hinged to each other, a connecting block is arranged at the outer side of the free end of one of the two semicircular steel rings, the connecting block is provided with a threaded hole, and a fixed bolt is in threaded connection with the threaded hole; a protruding block is arranged at the outer side of the free end of the other steel ring, the protruding block is provided with a mounting hole, a nut is arranged in the mounting hole, the nut is in interference fit with the mounting hole, cover plates are arranged at the two ends of the protruding block, and the cover plates are detachably connected with the protruding block. By means of the house cylindrical pouring formwork and the construction method, the steel band can be pre-tightened rapidly, and construction efficiency is improved; formwork burst is effectively prevented, and potential safety hazards are decreased.

Description

technical field [0001] The invention relates to the technical field of house construction, in particular to a formwork for pouring house cylinders 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 experience to roughl...
