Balcony beam slab inner side filling wall body and main body structure integral casting construction method

Abstract

The invention relates to a balcony beam slab inner side filling wall body and main body structure integral casting construction method. According to the construction method, the twice structure casting is put forward before the casting step; and a cast filling wall is arranged in grooves formed in the inner side of a beam steel bar and the inner side of a flange steel bar, and is integrally cast with a main body structure. The construction method has the advantages that the manufacturing of a formwork is simple; the reinforcement is convenient; a hollow mold is omitted; the supporting and the dismounting are convenient; building body materials used by a secondary structure are used in advance; the filling wall building work amount of the secondary structure is reduced; meanwhile, the work procedure clearance time is reduced; the integral economic benefits are good; the construction quality is high; the number of times of using a scaffold during the later-stage building is reduced; and the problems of construction quality and construction loss due to aerated concrete block cutting during the later-stage building are avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for integral pouring of a filling wall body inside a balcony beam slab and a main structure. Background technique [0002] During the construction of the balcony, the construction of the filling wall inside the balcony beam slab is relatively cumbersome. figure 1 As shown, it is composed of balcony flange 19 and balcony beam 13, wherein the balcony beam 13 is L-shaped, and the balcony flange 19 is inverted L-shaped. There is a platform plate 14 between the balcony flange 19 and the balcony beam 13. The traditional The construction method is as follows: firstly make the formwork for the groove X of the balcony beam 13 and the ear, pour concrete into the formwork and wait for it to be cured and solidified, then form the groove X on the inner side of the balcony beam plate through the beam groove formwork, and pass the beam The formwork for the protruding ...

AI Technical Summary

Problems solved by technology

[0003] (1) The groove formwork and the formwork at the ear are troublesome to make, not easy to reinforce and dismantle. Usually, the construction method must make a hollow mold, and the reliability of the hollow mold installation and fixing is difficult to guarantee;

[0004] (2) It is difficult to remove the formwork, and the damage rate of the formwork is high, and the construction personnel usually cannot complete the one-time, non-damaged formwork removal;

[0005] (3) Concrete vibration must be strengthened at the parts with lifting ears. The lower lifting ears are easy to leak vibration. It is difficult to guarantee the construction quality of the structure after vibration. It is difficult to remove the hollow mold. The masonry needs to install and dismantle the scaffolding three times, which increases the amount of work;

[0006] (4) The filling of the aerated block in the later stage requires multiple cuts before it can be inserted into the groove, resulting in a large amount of construction loss of the aerated block;

[0007] (5) The groove does not conform to the shape modulus of the aerated block, resulting in super thick plastering in the later stage
