Construction method of drilling bolt fastener type formwork supporting system

Abstract

The invention discloses a construction method of a drilling bolt fastener type formwork supporting system. The construction method comprises the steps that 1, joint bars (1), side formworks (2), positioning pipes (3), connecting pipes (4) and bolt fasteners (5) are prepared; 2, joint bar lines are symmetrically arranged on cushion layers (7) on the outer sides of the two side formworks; 3, the joint bars are arranged along the joint bar lines, and the multiple joint bars are symmetrically arranged on the two sides of the two side formworks; 4, the lower ends of the positioning pipes are sleeved with the joint bars and attached to the outer walls of the side formworks, and the upper ends of the positioning pipes are higher than the upper ends of the side formworks; 5, the connecting pipes are connected with the positioning pipes through the bolt fasteners, and the two positioning pipes and the connecting pipes are connected to form an inverted-U-shaped supporting system which is arranged on the outer sides of the two side formworks in a sleeving mode; 6, the steps 4-5 are repeated, and a plurality of supporting systems are arranged in the length direction of a building part at intervals; and 7, concrete is poured. The formwork of the building part can be effectively supported and reinforced, and the construction quality of the formwork and the building part is guaranteed.

Description

technical field [0001] The invention relates to a construction method of a building formwork, in particular to a construction method of a drill bolt fastener type formwork support system. Background technique [0002] In the construction of construction projects, building components such as beams and columns need to be installed with formwork before concrete pouring, and the formwork is supported and fixed through the support system to avoid mold expansion and grout leakage during concrete pouring and other construction processes. There are usually two types of formwork support in the prior art: one is to tie the formwork on both sides with the tie bolts to achieve the purpose of strengthening the side formwork, but the mounting plate of the tie bolts needs to be drilled on the side formwork, which reduces to a certain extent The strength of the side form is shortened, and the service life is shortened. At the same time, there are problems such as complicated installation pr...

Problems solved by technology

There are usually two types of formwork support in the prior art: one is to tie the formwork on both sides with tension bolts to achieve the purpose of strengthening the side form, but the mounting plate of the tension bolt needs to be drilled on the side form, which reduces the cost to a certain extent. The strength of the side form is shortened, and the service life is shortened. At the same time, there are problems such as complicated installation procedures, time-consuming and labor-intensive installation of the pull bolts.

The second is to set a support structure on the outside of the side form. The support structure is usually a diagonal brace and requires a load-bearing fulcrum, which requires a certain construction space, which is not conducive to the construction, and cannot be used in occasions where the construction space is limited.
