Single-sided erecting-formwork oblique throwing support device adopting flower basket screws and construction method for single-sided erecting-formwork oblique throwing support device

Abstract

The invention discloses a single-sided erecting-formwork oblique throwing support device adopting flower basket screws and a construction method for the single-sided erecting-formwork oblique throwingsupport device. The device comprises a side wall template, a template pressure beam, a steel tube inclined throwing support, an anti-floating reinforcement ring and flower basket screws, wherein theside wall template is arranged outside a structural side wall; the template pressure beam is arranged outside the side wall template; the upper and lower ends of the template pressure beam are fixed and riveted by a horizontal pull rod; one end of the steel tube inclined throwing support is connected with the template pressure beam for reinforcing the template pressure beam, and the other end of the template pressure beam is connected to a bottom plate; the anti-floating reinforcement ring is pre-embedded into a chamfer position at a joint of the bottom plate and the structural side wall; andthe flower basket screws are connected with the template pressure beam and the pre-embedded anti-floating reinforcement ring for vertically restraining and horizontally reinforcing again. The single-sided erecting-formwork oblique throwing support device adopts the flower basket screws to provide template anti-floating force and template prefabricating and splicing, optimizes the structural supporting form and the plate surface system of the template, overcomes quality common problems such as swelling, slurry leaking and slab staggering due to the fact that the oblique throwing support systemfloats, and guarantees perpendicularity and flatness of a wall body. The single-sided erecting-formwork oblique throwing support device is convenient in process construction, is good in economical efficiency, guarantees engineering quality, and greatly optimizes a single-sided erecting-formwork supporting system.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and mainly relates to a device and a construction method for formwork support of U-shaped groove side walls, basement (underground space) outer walls, etc. device and its method of construction. Background technique [0002] In the construction of many underground space side walls, box culvert structures, and U-shaped troughs in rivers, the structural side walls cannot use double-sided formwork due to the constraints of the construction site, and the single-side formwork method is used. The single-side formwork process usually uses steel pipes to erect bent frames as the support system of the formwork. This process requires high construction space, uses a large number of steel pipes, takes a long period of erection, and requires a large amount of labor. Defects such as expansion mold, concrete wall flatness, and poor verticality make it difficult to guarantee the construction qu...

AI Technical Summary

Problems solved by technology

The traditional single-sided vertical formwork generally uses a support system composed of full-scale scaffolding and formwork square timber. When encountering simultaneous construction of multiple processes, narrow working space, tight construction period requirements, tall wall formwork support, and difficult construction, traditional single-sided vertical formwork is often used. The surface mold cannot meet the requirements
