Concrete structure wall column corner wood formwork reinforcing method

Abstract

The invention discloses a concrete structure wall column corner wood formwork reinforcing method. According to the method, a formwork panel, double-faced adhesive tape, wood lumps, an iron plate, reinforcing double steel pipes and double accessories are included; one end of each reinforcing double steel pipe is provided with one accessory, the ends, provided with the double accessories, of the two reinforcing double steel pipes are connected, the inner sides of the reinforcing double steel pipes are connected with the iron plate and the wood lumps, and the wood lumps are connected with the formwork panel. During installation of a concrete structure wall column corner wood formwork, closing joints of the formwork panel 1 are bonded through the double-faced adhesive tape, and the 50*100 wood lumps which are 2,000-mm long are used for covering the joints completely and ceaselessly along the floor height; after the wall column corner formwork is corrected and reinforced, an accessory is added to the accessory of each reinforcing double steel pipe to form double accessories, the situation that formwork expansion is caused by quality problems of the accessories is prevented, the construction level is increased, construction quality is ensured, a construction method is simplified, the later cost is reduced, and the concrete appearance quality is improved.

Description

technical field [0001] The invention relates to a method for reinforcing a corner wood formwork of a wall column of a concrete structure. Background technique [0002] Concrete structure wall column angle wood formwork is usually assembled with 12mm thick composite plywood as the panel, and then 50×100 square wood as the back. After the size is processed, it is prefabricated with square wood lining around the back of the panel, and then installed on site. Due to the existing construction technology is not rigorous, and human factors, this kind of scheme often cannot eliminate the phenomenon of grout leakage. Leading to the occurrence of quality defects such as pockmarks and blisters at the corners of the wall columns: First, because the strength of the panel itself cannot meet the requirements for use, when pouring concrete, the strength of the formwork cannot compete with the pressure generated by the concrete during vibration, resulting in The panel at the formwork swells...

[0002] Concrete structure wall column angle wood formwork is usually assembled with 12mm thick composite plywood as the panel, and then 50×100 square wood as the back. After the size is processed, it is prefabricated with square wood lining around the back of the panel, and then installed on site. Due to the existing construction technology is not rigorous, and human factors, this kind of scheme often cannot eliminate the phenomenon of grout leakage. Leading to the occurrence of quality defects such as pockmarks and blisters at the corners of the wall columns: First, because the strength of the panel itself cannot meet the requirements for use, when pouring concrete, the strength of the formwork cannot compete with the pressure generated by the concrete during vibration, resulting in The panel at the formwork swells, resulting in the occurrence of grout leakage; second, because the square wood on the back is not strong enough, although it is reinforced with steel pipes, the pressure generated during the concrete vibration and the fixation of the steel pipe can cause the square wood to The deformation of the cross section of the mold will further lead to the expansion of the panel at the mold clamping place, resulting in the occurrence of grout leakage; the third is that the technical level of the workers is uneven, and there will be human errors when the formwork is installed and reinforced, which also causes the workers Artificial gaps are created during the installation of wooden formwork, which in turn causes grout leakage.
