Embodiment Construction

[0026] The structural features of the present invention will now be described in further detail in conjunction with the accompanying drawings.

[0027] A construction method for reserving structural column holes on beam slabs is carried out according to the following steps:

[0028] Step one (see figure 1 ): Splicing the beam-slab formwork frame 3 for pouring the beam-slab with construction formwork; placing the slope-shaped steel plate base 11 at the position where the structural column needs to be set in the beam-slab formwork frame 3; the bottom surface size and structure of the slope-shaped steel plate base 11 The size of the column is consistent, and the top surface of the slope-shaped steel plate base 11 is smaller than the size of the bottom surface, which is a thin metal plate with a small top and a large bottom, and a slope shape around it;

[0029] Step two (see figure 1 ): four or more hole positioning rods 12 are welded vertically on the top surface of the slope-...

Abstract

The invention provides a construction method for reserving constructional column holes in a beam plate so as to overcome defects of existing constructional column reinforcing steel bar embedding construction methods. The construction method comprises the steps as follows: a beam plate template frame used for casting the beam plate is spliced through construction templates; a slope-shaped steel plate base is placed in a position, where a constructional column is required to be arranged, within the beam plate template frame; four hole positioning rods are perpendicularly welded on the top surface of the slope-shaped steel plate base; surfaces of the slope-shaped steel plate base and the hole positioning rods are coated with a release agent; each hole positioning rod is sleeved with a PVC (polyvinyl chloride) bushing, a cavity of the beam plate template frame is filled with concrete slurry, and the concrete slurry is solidified to become the concrete beam plate; and the beam plate template frame, the PVC bushings, the slope-shaped steel plate base and the hole positioning rods are disassembled. The construction method has the advantages as follows: the method is simple in procedure, high in operability and low in construction difficulty, and the strength of the beam plate is not damaged, so that the construction cycle is shortened, manpower and material costs are saved, and the structure quality of a building is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction and relates to the construction of structural column steel bars in the secondary structure of the building engineering. Specifically relates to a construction method for reserving structural column holes on beam slabs. Background technique [0002] In order to improve the seismic performance of the masonry structure of multi-storey buildings, it is necessary to install reinforced concrete columns in the appropriate parts of the masonry of the house and connect them with the ring beams to jointly enhance the stability of the building. This reinforced concrete column is usually called a structure. column. The traditional method of structural column reinforcement is generally to plant reinforcement by drilling after the concrete pouring of the beam and slab is completed. Its construction process generally includes: construction preparation, fixed-point positioning, drilling, cleaning o...
