Abstract
The utility model provides a fish-bellied steel truss, particularly aiming at providing a fish-bellied steel truss for the formwork supporting operation in the construction, which belongs to the field of building equipment. The fish-bellied steel truss is composed of a top chord, a web member and a broken-line-shaped lower chord. The two ends of the broken-line-shaped lower chord are connected with the two ends of the top chord; the top and the lower ends of the web member are welded between the top chord and the broken-line-shaped lower chord, and are arrayed in branch moment graph, taking the shape of the fish belly; the two ends of the top chord are connected with telopodite plates. Compared with the prior art, the utility model has the characteristics of reasonable design, simple structure, easy processing, convenient using, labor saving, time saving and large bearing capacity. Thus, the utility model has good popularization and using value.
Description
1, technical field
The utility model relates to a kind of building implements, specifically for the building operations form erecting operation provides a kind of fish-bellied type steel truss, belongs to the building implements field.
2, technical background
The truss formwork is a kind of mold method of labor and material saving in the building operations operation, but the in use existing deficiency of the truss of prior art is that supporting capacity is on the low side, the scope of application is restricted, and quality accidents easily takes place, so do not re-use, adopt steel pipe pin hand generation to do template at present mostly and support, or adopt still that wood is stupefied to be supported as template with pin, the former materials are more, and the latter is not inconsistent state basic policy.At present also not having comparatively ideal is that labor and material saving, the supporting capacity truss that the scope of application is wide greatly, again is used for building operations.
3, summary of the invention
It is that labor and material saving, supporting capacity greatly, also have the wide fish-bellied type steel truss of the scope of application that the purpose of this utility model provides a kind of.
The purpose of this utility model realizes in the following manner, adopt steel pipe to make upper chord and be used to put template, web member and broken line shape lower chord adopt reinforcing bar to make, the two ends of broken line shape lower chord and the two ends of upper chord join to being bent downwardly and form arcuation down, the two ends up and down of web member are welded between upper chord and the broken line shape lower chord, supporting capacity can reach 20KN/m like this, be original truss 3-5 doubly, maximum defluxion 0.6cm, can be common to the direct support of plate, beam, post, wall, basic mode plate, can save stupefied greatly.
Accompanying drawing is the structural representation of fish-bellied type steel truss.
4, description of drawings
Explain below with reference to Figure of description fish stomach shape steel truss of the present utility model being done.
Fish stomach shape steel truss of the present utility model, its structure are by top boom 1, web member 3 and fold-line-shaped lower edge Bar 2 consists of, and the two ends of the two ends of fold-line-shaped lower boom 2 and top boom 1 join, the up and down two ends weldering of web member 3 Be connected on and be freely-supported moment of flexure pattern arrangement between top boom 1 and the fold-line-shaped lower boom 2, shape such as fish belly are upper The two ends of chord member also are connected to end joint plate 4.
5, embodiment
Its processing and fabricating of fish-bellied type steel truss of the present utility model is very simple and convenient, gets final product by traditional sheet metal rivet welding processes making shown in the by specification accompanying drawing.The upper chord diameter is that the steel pipe of 48mm is made, and web member and broken line shape lower chord are made with reinforcing bar." freely-supported bending moment diagram " is the trussed construction term of architectural use.
One of feature of the present utility model: be to surround approximate freely-supported bending moment diagram, shape such as fish belly by upper chord and broken line shape lower chord.Chord member countershaft power is tending towards equal, and web member axle power is very little, and the technical and economic performance optimum is the ideal truss in the various forms; Two of feature: be each form web member and be all depression bar, can not establish plate in succession; Feature three: upper chord is the steel pipe of diameter 48mm, truss fixing and stable, available pin hand steel pipe and fastener need not to increase other accessories, lower chord and web member are reinforcing bar so that the building site process voluntarily and be out of shape after reparation.End joint plate adopts the steel plate of 6mm * 60mm * 220mm to connect, with the two-sided welding of upper and lower chord member.
Fish stomach shape steel truss of the present utility model is compared with existing technology, have reasonable in design, structure is simple Single, be easy to processing, easy to use, the characteristics such as bearing capacity is big, thereby, have well and promote the use of Be worth.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (1)
1. fish-bellied type steel truss, comprise upper chord, web member and broken line shape lower chord, it is characterized in that the two ends of broken line shape lower chord and the two ends of upper chord join, the two ends up and down of web member are welded on and are a moment of flexure pattern arrangement between upper chord and the broken line shape lower chord, shape such as fish belly also are connected to end joint plate at the two ends of upper chord.
