Abstract

The invention belongs to the technical field of concrete formworks, and relates to a detachable self-supporting type steel bar truss formwork. The technical scheme is as follows: the detachable self-supporting type steel bar truss formwork mainly comprises a self-supporting type steel bar truss and a bottom mould. The detachable self-supporting type steel bar truss formwork is characterized in that a reverse U-shaped steel strip which fixes the self-supporting type steel bar truss and the bottom mould penetrates out of the bottom mould after surrounding a steel bar positioned at the bottom of the chord member of the self-supporting type steel bar truss; and both ends of the iron rod are respectively fixed at the outer side of the bottom mould by using nuts. The detachable self-supporting type steel bar truss formwork disclosed by the invention can save the resources and reduce the cost by saving a large quantity of bottom formwork materials and obviously improve the environment of a construction site with the decrease of original branch mould systems. According to the invention, the reverse U-shaped steel strip can also be used as the fixing part of the lower hanging piece of a demoulded concrete formwork.

Description

A kind of removable lining self-bearing type reinforcement bar truss mould plate

Technical field

The invention belongs to fixed buildings Structural Engineering field, relate in particular to the concrete blinding technical field.

Background technology

Usually the self-bearing type reinforcement bar truss mould plate is to be fixed together with welding manner by the steel sheet of steel bar girder with soffit formwork, treat concrete floor water smash finish after, the self-bearing type reinforcement bar truss mould plate just combines with concrete floor is permanent.Serving as the steel sheet of soffit formwork for good and all stays on the floor.After time was permanent, the easy corrosion of steel-sheet bed die can influence use, and also soffit formwork can come off after the possibility welding position corrosion, and potential safety hazard is arranged.Simultaneously, bed die is stayed also very waste on the concrete slab.

Summary of the invention

Technical problem to be solved by this invention has provided a kind of removable lining self-bearing type reinforcement bar truss mould plate, and soffit formwork can shirk after casting and compacting of concrete is finished down, and template can be reused.

Technical scheme of the present invention is: a kind of removable lining self-bearing type reinforcement bar truss mould plate, mainly comprise self-bearing type steel bar girder and bed die composition, the inverted U-shaped steel bar of fixing described self-bearing type steel bar girder and described bed die, pass described bed die behind the chord member bottom reinforcement bars of described self-bearing type steel bar girder, the two ends of described steel bar are fixed on the outside of described bed die respectively with nut.The bed die material can be a steel sheet, also can be other all can do the material of concrete bed die.

The present invention is according to the traditional concrete blinding technology and the characteristics of self-bearing type reinforcement bar truss mould plate, the self-bearing type reinforcement bar truss mould plate need not be supported can shirk with the conventional template system combine, be about to the connected mode of self-bearing type steel bar girder, change removable lining connected mode into the fixedly welding of bed die.On the bed die face, coat release agent before the casting and compacting of concrete, after casting and compacting of concrete is finished, can shirk soffit formwork down like this, template can be reused.This removable lining self-bearing type reinforcement bar truss mould plate can be saved a large amount of soffit formwork materials, economizes on resources, reduces cost.The system of touching that the environment of job site also should be original simultaneously reduces and improves significantly.Inverted U-shaped steel bar can also be as the fixture of the following suspender member of concrete blinding after the demoulding.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing and example and application construction method.

Fig. 1 is a self-bearing type reinforcement bar truss mould plate longitudinal plan.

Fig. 2 is a detachable connection node of the present invention.

The specific embodiment

Self-bearing type steel bar girder 1 has bed die 3 as depicted in figs. 1 and 2, and steel bar 4 penetrates described bed die 3, passes described bed die 3 behind the chord member bottom reinforcement bars 2 of self-bearing type steel bar girder, and the two ends of described steel bar are fixed on the outside of described bed die 3 respectively with nut 5.

More than scheme provided by the present invention is introduced in detail, for one of ordinary skill in the art, according to the thought of the embodiment of the invention, other self-bearing type steel bar girder is with the mode of the detachable connection of the template part that all can change.In sum, this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.

Claims (1)

1. removable lining self-bearing type reinforcement bar truss mould plate, mainly comprise self-bearing type steel bar girder and bed die composition, it is characterized in that: the inverted U-shaped steel bar of fixing described self-bearing type steel bar girder and described bed die, pass described bed die behind the chord member bottom reinforcement bars of described self-bearing type steel bar girder, the two ends of described steel bar are fixed on the outside of described bed die respectively with nut.
