Description

Technical Field

[0001] The invention relates to the field of structural column construction technology, in particular to a structural column construction process at the junction of inner and outer wall blocks with different base elevations. Background Art

[0002] Concrete frame structures are widely used in residential buildings, schools, office buildings, and hospitals. Prestressing of concrete beams or slabs is also applied as needed to suit larger spans. Frame steel structures are often used in large-span public buildings, multi-story industrial plants, and some special-purpose buildings, such as theaters, shopping malls, gymnasiums, railway stations, exhibition halls, shipyards, hangars, parking lots, light industrial workshops, etc. The frame structure is composed of beams and columns connected by steel bars to form a load-bearing system, that is, the frame composed of beams and columns jointly resists the horizontal and vertical loads that occur during use. The frame building has flexible space division, light weight, and saves materials. It has the advantage of being able to flexibly cooperate with the building plan layout, which is conducive to arranging building structures that require a larger space.

[0003] However, the walls of frame-structured houses do not bear loads and only serve as enclosures and partitions. They are generally built or assembled using prefabricated aerated concrete, expanded perlite, hollow bricks or porous bricks, pumice, vermiculite, expanded clay and other lightweight panels.

[0004] There are bound to be various intersections in the process of wall construction for the internal filling walls of frame structures made of different materials. Because of the different construction processes of precast bricks made of different materials, the different material properties of precast bricks, the inconsistency of the base concrete elevation when the two bricks are laid, and the overall seismic structure requirements of the internal masonry walls of the frame structure, huge technical differences and quality problems have occurred in the construction treatment of the intersections of two or more precast bricks. Structural columns enhance the integrity and stability of the building. Reinforced concrete structural columns should also be set in the walls of multi-story brick-concrete structures and connected to the ring beams of each floor to form a spatial frame that can resist bending and shearing. This is an effective measure to prevent the collapse of houses. How to set up seismic-resistant structural columns to ensure the safety of the overall structure is the key research content at this stage. Summary of the invention

[0005] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a construction process for structural columns at the junction of inner and outer wall blocks with different base elevations.

Roughen the surface of the high concrete platform and the low concrete platform, install the full-length tie bars, and build the exterior and interior walls; S5.

Figure 1-Figure 5 The construction process of structural columns at the junction of inner and outer wall blocks with different base elevations includes the following steps: S1. Plant multiple vertical steel bars 50 on the concrete high platform 1 and the concrete low platform 2 respectively. The vertical steel bars 50 are threaded steel bars with a diameter of 14 mm. The thickness of the steel bar protective layer is required to be 15 mm. The cross section of the structural column 5 is T-shaped. S2. Stirrups 51 are provided. Stirrups 51 are made of threaded steel with a diameter of 6 mm. Densification areas are provided at one third of the upper and lower parts of the structural column 5. The spacing between stirrups 51 is 100 mm. The spacing between stirrups 51 in the non-densification area is 200 mm. The spacing between the starting stirrups 51 is 50 mm. S3, install hook bars 52 on the vertical steel bars 50 located on the concrete low platform 2. The hook bars 52 are made of threaded steel bars with a diameter of 6 mm, and the ends are bent at 135 degrees. The starting distance is 50 mm from the ground, and the distance between two adjacent hook bars 52 is 100 mm, until they are flush with the top surface of the concrete high platform 1; S4, before the template of the structural column 5 is closed, the top surface of the concrete low platform 2 and the side and top surfaces of the concrete high platform 1 are roughened, and two full-length tie bars with a diameter of 6 mm are set for every two bricks of the height of the outer wall blocks 3 and the inner wall blocks 4. The full-length tie bars extend into the middle of the structural column 5. The outer wall blocks 3 and the inner wall blocks 4 are laid in a "retreat first and advance later" manner from the bottom, and the roughened areas are moistened with water before pouring the concrete; S5. After the formwork of structural column 5 is firmly installed, concrete is poured. A bell mouth is set on the top of the formwork, and the concrete is poured and formed in one step.
