Construction method applied to welding punching of formwork

Abstract

The invention discloses a construction method applied to welding and punching of a formwork. The method comprises the following steps: step 1, mounting preparation: preparing a welding and punching device, placing the welding and punching device on one side of a vertical formwork, and directly facing the formwork; step 2, positioning and welding: starting a tin soldering mechanism to carry out spot welding on the part of the pipe orifice of the embedded sleeve clamped by the clamping piece to form a positioning point; step 3, fixed welding: after spot welding is completed, stopping tin soldering of the tin soldering mechanism, driving a chuck to move to the lower end of a rotating ring in the length direction of the chuck, and after the chuck is clamped to a supporting block at the lower end of the rotating ring, conducting line welding by the tin soldering mechanism on the rotating ring on the peripheral side of the pipe opening of the embedded casing pipe, and fixing the the pipe opening of the embedded casing pipe to the formwork; and step 4, drilling and holing: under the action of a second one-way bearing, driving a drill bit by a screw rod to move in the length direction of the screw rod and penetrating through the embedded sleeve to conduct drilling and holing on the formwork.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for welding and punching applied to templates. Background technique [0002] When the formwork is set up, some places often need to reserve sleeves. At this time, it is necessary for the carpenter to make holes in the fixed position of the formwork before the formwork is set up. The holes made by ordinary methods are irregular and the work efficiency is low. , if there is a large gap between the embedded casing and the concrete, it is easy to leak the grout when pouring the concrete, resulting in defects in the quality of the concrete. [0003] In order to solve the above technical problems, the Chinese patent document (publication number is CN209792675U) discloses a construction method for opening a simple formwork, including an electric drill body and a drill bit, the drill bit includes a main shaft, one end of the main shaft is connected wit...

Problems solved by technology

[0004] The above scheme can only be applied before the formwork is set up. Therefore, when the formwork is set up, it is easy to appear that the size of the hole opened at the fixed position is inconsistent with the size of the embedded casing, and there is a risk of grout leakage; secondly, it is installed on site. At the same time, due to the large number of formwork, it is easy to appear that some formwork has not been opened before the formwork is supported, and it is necessary to replace the formwork or re-open the hole on site, thus prolonging the construction progress; finally, because the position of the formwork hole is usually It is measured manually, so it is prone to error
