Movable formwork supporting truss and construction method thereof

A technology for supporting trusses and moving formwork, which is applied to the preparation of formwork/formwork/work frames, pillars, and building components on site. It can solve the problems of low utilization rate, failure to turn around the frame pipes in time, and increase construction costs. Achieve the effect of saving manpower and material resources and considerable economic benefits

Problems solved by technology

[0004] The previous construction methods have the following disadvantages: 1) In order to remove the formwork at the same time, the support time of the frame tubes of the slab must be equal to the support time of the beam frame tubes. 2) The conventional method of supporting formwork is to assemble a single piece of frame pipe, and dismantle the single piece, which takes a long time and wastes manpower and material resources; 3) The formwork of the beam and slab is full of scaffolding, which occupies a huge amount of construction materials at one time

Embodiment 1

[0046] In this embodiment, the supporting rods are all made of 48mm×3.5mm steel pipes, and the connecting fasteners 4 are used to connect each rod. The top of the vertical rod 1 is connected, and the two ends and the middle position of the diagonal brace 3 are connected and fixed with the vertical rod 1 by the fastener 4.

[0047] The connecting fastener 4 is a fastener commonly used in construction. Among them, the right angle fastener (cross buckle) is used for the connection of two vertically intersecting steel pipes; the rotary fastener (swivel buckle) is used for the connection of two cross steel pipes at any angle; the butt joint fastener (one-word buckle) is used for two Steel pipe butt connection. A stable supporting truss that forms a fixed unit according to the size of the roof beam slab structure to be constructed.

[0048] The steel casing 6 is a Φ63 steel pipe, and an inner baffle 61 is arranged on the inner side of its lower part. The inner baffle 61 is an annu...

Abstract

The invention relates to a movable formwork supporting truss and a construction method thereof. The movable supporting truss comprises a supporting rod assembly, a connecting buckle, adjustable supports and universal wheels. The supporting rod assembly is composed of stand rods, horizontal rods and inclined struts, and a truss structure is formed through the connecting buckle. The adjustable supports are placed at the upper ends and the lower ends of the stand rods and used for adjusting the supporting height, and when the adjustable supports on the lower portions of the stand rods are replaced by the universal wheels, the whole truss can move. The construction method comprises the steps of ground leveling, single rod piece assembling, overall truss assembling, overall truss removing, recycling and the like. Compared with the prior art, the movable formwork supporting truss and the construction method thereof have the advantages that the construction efficiency and the material recycling usage rate are increased by two or more times compared with a traditional construction method, labor and material resources are saved, the economical benefits are appreciable, the movable formwork supporting truss is especially suitable for a cross beam structure and the construction occasions with regular and orderly bay sizes and can also be used in a beamless slab construction, wherein the construction occasions include superstores, office buildings, underground garages and other frame structures with post-cast strips.

Description

technical field [0001] The invention relates to a truss for building construction, in particular to a movable formwork support truss and a construction method thereof. Background technique [0002] In building construction, the supporting trusses of the beam formwork are generally erected and dismantled together with the supporting trusses of the floor formwork, but usually the formwork removal time of the beam is longer than that of the floor slab, see the table below. [0003] Floor formwork Beam Bottom Formwork Clear span distance 3-6m, live load not greater than static load: 7 days Clear span distance 3-6m, live load not greater than static load: 14 days Clear span distance 3-6m, live load is greater than static load: 4 days Clear span distance 3-6m, live load not greater than static load: 7 days Clear span distance 6m, live load not greater than static load: 10 days Clear span distance 6m, live load not greater than static lo...
