Embodiment 1

[0028] Embodiment 1: In this embodiment, the construction of an underground project is taken as an example. The steel formwork 3 for the exterior wall of the basement is spliced ​​by a plurality of standard plates with a specification of 2000mm (length) × 4200mm (height). The horizontal back ribs, vertical back ribs constitute the skeleton and the panel connected with the frame bolts. The panel is a cold-rolled steel plate with a thickness of 5mm. The size of the panel needs to be adjusted according to the actual situation of the basement exterior wall 2. The ribs are all made of channel steel, the distance between two adjacent horizontal back ribs is 250mm, the distance between two adjacent vertical back ribs is 2m, and the two adjacent standard plate bolts are connected as a whole.

Embodiment 2

[0038] Embodiment 2: Combination Figure 1 to Figure 5 Illustrate the construction method of the basement exterior wall unilateral steel formwork support system of the present invention, concrete steps are as follows:

[0039] S1: Bind the steel bars of the exterior wall of the basement and check and accept it. A pair of rails 10 are pre-embedded on the foundation floor 1. The head bolts assemble and connect the exterior wall steel formwork 3 and the support truss 50 into a whole and hoist them to the construction site. After the installation base 20 and the support truss 50 are in place, connect the adjustment rod 60 between the base 20 and the support truss 50 and the diagonal brace 70, install the ground anchor assembly 30 to firmly fix the base 20 on the foundation floor 1, and when the ground anchor assembly 30 is pre-embedded, it is necessary to pull the wire through to ensure that the ground anchor assembly 30 on the same side is on the same straight line, ensuring that...

Abstract

The invention provides a basement outer wall single-side steel formwork supporting system and a construction method thereof, and relates to the technical filed of constructional engineering equipment. Aiming at the problems that the labor intensity of construction personnel is high and formwork supporting work efficiency is low existing in the available supporting system, the basement outer wall single-side steel formwork supporting system and the construction method thereof are provided. The basement outer wall single-side steel formwork supporting system comprises a pair of tracks, bases, and a plurality of supporting trusses, wherein the pair of tracks is laid at a foundation slab and parallel to an outer wall steel formwork, the bases are arranged on the tracks and can slide along the tracks, and the multiple supporting trusses are vertically arranged at intervals and are connected with the outer wall steel formwork; and bottom parts of the supporting trusses are hinged to the bases, and the supporting trusses are detachably connected with top ends of the bases through a plurality of adjusting rod pieces. The construction method comprises the steps that the steel formwork supporting system is spliced and fixed, after outer wall concrete is poured, a ground anchor assembly and a diagonal bracing are disassembled, an adjusting rod piece is retracted, so that the demoulded outer wall steel formwork are made to be supported on the base, and the next working section is started to continue pouring construction of outer wall concrete.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, in particular to a single-side steel formwork support system for a basement exterior wall and a construction method thereof. Background technique [0002] At present, the construction of the cast-in-place concrete exterior wall of the basement uses a single-side support formwork to fix the external wall steel formwork. The single-side support formwork mainly uses the steel triangular truss and embedded parts as the support system of the formwork. The installation of steel triangular trusses requires high labor intensity for construction workers and low formwork efficiency. Moreover, some steel formwork for external walls cannot be reused, resulting in waste of materials. Contents of the invention [0003] Aiming at the support system of the existing steel formwork for the exterior wall of the basement, there are problems of high labor intensity for construction person...
