A foundation pit support template for building foundation construction

Abstract

The invention belongs to the technical field of building construction equipment, and in particular relates to a foundation pit support template for building foundation construction, which includes a rectangular base plate, the two sides of the base plate are rotatably connected with a strip-shaped mounting plate; the mounting plate is slidably fitted with a sliding plate parallel to it , the outer end surface of the sliding plate is perpendicular to the sliding plate and is fixed with a strip pressure plate; the connection between the mounting plate and the base plate is provided with an angle adjustment mechanism; the top and bottom of the base plate are respectively rotated by pin shafts to install several anchors for fixing support The installation block of the rod; the position corresponding to the installation block on the back of the base plate is connected to one end of the first connecting rod through the rotation of the pin shaft, and one end of the second connecting rod is connected to the mounting block through the rotation of the pin shaft, and the first connecting rod and the second connecting rod The ends are hinged together. The invention can adjust the angle according to the radian of the surface of the arc-shaped foundation pit, so as to ensure that the bar-shaped pressing plate can be attached to the surface of the foundation pit and fully support the surface of the side wall of the arc-shaped foundation pit.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a building foundation foundation pit support formwork. Background technique [0002] In the process of building foundation construction, if the depth of the foundation pit exceeds five meters, in order to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, it is necessary to add support to the side wall of the foundation pit, that is, to adopt support and reinforcement for the side wall of the foundation pit and protective measures. During the installation of the foundation pit support, the support pile is now inserted into the soil at the bottom of the pit to the hard soil layer, and the anchor rod is installed on the support pile, and the anchor rod is inserted into the soil on the side wall of the foundation pit to prevent the side wall of the foundation pit. The soil is fixed, ...

Problems solved by technology

[0004] The invention provides a foundation pit support formwork for building foundation construction, and aims to solve the following problems in the use process of the existing foundation pit support formwork: (1) the support formwork is difficult to fit well with the surface of the arc-shaped foundation pit The surface of the side wall of the arc-shaped foundation pit cannot be fully supported; (2) The support template and the anchor rod are connected by threads, and the installation and disassembly are relatively stable and easy to loosen; (3) In the sand layer Or in the muddy soil layer, the support anchor rod is easy to be pressed into the soil to cause settlement, which in turn drives the support formwork to sink, seriously reducing the support effect of the support formwork on the surface of the side wall of the foundation pit
