Problems solved by technology

[0007] ① The cost of structural columns is high, among which the cost of longitudinal bars, stirrups and concrete itself is high, and the labor costs of construction personnel are also high. In most areas, the formwork of structural columns needs to be prepared by the house builder, and some use wooden formwork. It is more expensive to purchase, and it cannot be reused after construction; some use leased steel formwork, and the lease fee is more expensive;
[0008] ② The construction of structural columns takes up the construction period. Generally, farmers build houses in slack time, and most of them build new houses on the original site after the old houses are demolished. When building new houses, they usually live in tents, so the requirements for the construction period are relatively urgent.
There is no formal building materials market in rural areas, and the quality of many raw materials is difficult to guarantee, and subject to cost and cost constraints, homeowners and construction teams want

Embodiment 1

[0068] As shown in Figure 1, a structural column for a masonry structure is characterized in that it is mainly assembled from prefabricated sections 2 with four longitudinal reinforcements 1; the vertical reinforcements 1 of adjacent prefabricated sections 2 It is a binding connection; there is a horse-tooth bar 5 engaged with the wall 10 on the construction column; the above-mentioned longitudinal reinforcement 1 is interspersed in the four corners of the regular square prism 6 in the above-mentioned prefabricated section 2 along the vertical axis; the structure of this embodiment The column is suitable for the middle part of the in-line wall; the prefabricated section used has two curbs on the same line.

Embodiment 2

[0070] As shown in Figure 2, a structural column for masonry structures is characterized in that it is mainly composed of prefabricated sections 2 with four longitudinal reinforcements 1 and cavities 3; the upper and lower adjacent prefabricated sections 2 The longitudinal rib 1 is welded; the cavities 3 of the upper and lower prefabricated sections 2 overlap to form the cavity 4 of the structural column, and the cross section of the cavity 4 is circular; the structural column has a buttress 5 engaged with the wall 10; The above-mentioned longitudinal ribs 1 are interspersed in the four corners of the regular square prism 6 in the above-mentioned prefabricated section 2 along the vertical axis; the construction column of this embodiment is suitable for a T-shaped wall; the prefabricated section used has three horse teeth. Of course, concrete can also be poured into the cavity of the construction column in this embodiment as required.

Embodiment 3

[0072] As shown in Figure 3, a structural column for masonry structures is characterized in that it is mainly composed of prefabricated sections 2 with four longitudinal reinforcements 1 and cavities 3; the upper and lower adjacent prefabricated sections 2 The longitudinal reinforcement 1 is bound and connected; the cavities 3 of the upper and lower prefabricated sections 2 overlap to form the cavity 4 of the structural column, and the cross section of the cavity 4 is circular; ; The above-mentioned longitudinal reinforcement 1 is interspersed in the four corners of the regular square prism 6 in the above-mentioned prefabricated section 2 along the vertical axis; the construction column of this embodiment is suitable for L-shaped walls; the used prefabricated section has two mutually perpendicular Ma Yacha. Of course, concrete can also be poured into the cavity of the construction column in this embodiment as required.

Abstract

The invention provides a constructional column for a masonry structure, which is characterized in that the constructional column is mainly formed by assembling precast segments (2) with longitudinal ribs (1). The invention also provides a method for preparing the constructional column for the masonry structure and special precast segments thereof. The preparation of the constructional column according to the method has low cost, because, on one hand, the precast segments can be produced in precast component factories, have a simple production technology, and are convenient to be promoted in the precast component factories in rural areas, and the industrialized production can reduce the cost to ensure that the cost for the constructional column is reduced; on the other hand, no formwork supporting is needed during the construction of the constructional column, thereby saving the cost for raw material purchase (or the tenancy of a steel formwork) of a formwork and the labor cost such as the manufacture, supporting and removal of the formwork and so on; and a hollow constructional column can be adopted in a low seismic fortification intensity area, the cost for a concrete material in a cavity part can be saved, and the labor cost can also be saved due to the fact that no wet operation is needed on the spot.

Description

technical field [0001] The invention relates to a construction column for a masonry structure, and also relates to a preparation method and a special prefabricated joint of the construction column for a masonry structure. Background technique [0002] In the Tangshan earthquake, due to its poor integrity, masonry structures collapsed and were severely damaged, posing a great threat to people's lives. After the Tangshan earthquake, Chinese structural anti-seismic researchers proposed the technology of adding structural columns and ring beams to traditional masonry structures. Structural columns have the following functions: ① Improve the shear strength of the wall; ② greatly improve the deformation capacity of the wall and the house; ③ form a restraint system together with the ring beam, which can effectively limit the development and scattering of cracks in the wall and ensure the don't collapse. Previous earthquake damages have shown that the construction of column ring b...
