Joint of mould plate supporting and locating device for wall building and mould plate supporting and locating device for wall building

Abstract

This invention provides a kind of joint of the building form board supporting fixing location device. It includes the cone cover and the centre thread connecting pipe, the head of the thread connecting pipe is in the connection shape which matches the implement, there is space between the head of the centre thread connecting pipe and cover, which can be for an implement entering. The joint provided in this invention is able to be dismantled after the building of wall body is finished, and the centre screwed hole can be bridge connection of the supporting and fixing structure inside and outside the form board, it is convenient for the structure of the supporting and fixing device to be optimization and proper, to make the wall body won't be through-hole after the supporting and fixing device being dismantled. The said centre thread connecting pipe is divided with the cone cover, the cone cover sets centre stepped hole, centre thread connecting pipe is inserted in the stepped hole and it sets the boss which matches the stepped hole. This invention also provides a kind of building form board supporting fixing location device. It includes a pair of the said joint, it also includes the centre rod which links the said pair of joint, both ends of the centre rod has the thread matches the centre thread connecting pipe, it includes the external screw which connect the gas thread of the centre thread connecting pipe.

Description

technical field [0001] The invention relates to a formwork supporting and positioning device for building concrete walls and its accessories. Background technique [0002] When building a cast-in-place concrete wall, it is necessary to use a formwork support positioning device to position the formwork on both sides according to the design spacing, so that the wall poured between the formwork meets the design thickness. The current formwork support and positioning device often uses U-shaped steel bars corresponding to the thickness of the wall between the formwork on both sides to determine the distance between the formwork, and then sets the connecting screw through the formwork on both sides, and uses nuts and gaskets outside the formwork on both sides. The parts are connected with the screw to position the formwork, and the part between the formwork on both sides is covered with pipes. When the wall is poured, the connecting screw is pulled out fr...

Problems solved by technology

The current formwork support and positioning device often uses U-shaped steel bars corresponding to the thickness of the wall between the formwork on both sides to determine the distance between the formwork, and then sets the connecting screw through the formwork on both sides, and uses nuts and gaskets outside the formwork on both sides. The parts are connected with the screw to position the formwork, and the part between the formwork on both sides is covered with pipes. When the wall is poured, the connecting screw is pulled out from the pipe, but the pipe cannot be taken out and remains in the wall. Form a through hole through the wall, even if the hole is filled later, it will still affect the anti-leakage performance of the wall
