Abstract

The invention discloses a simple bearing type template truss, and the structure thereof is composed of a template, upper chord tendons, lower chord tendons and web bars, wherein the upper chord tendons and the lower chord tendons are arranged in an up-down parallel and spaced mode; the web bars at the two sides of the upper chord tendons and the lower chord tendons are formed by welding a plurality of inversed V-shaped first single web bars and second single web bars in a slant mode; the upper ends of the first single web bars and the second single web bars are respectively packed and welded on the upper chord tendons while the lower ends the first single web bars and the second single web bars are respectively welded on the two sides of the lower chord tendons, and the extension parts thereof are buckled and fixed on the template by welding horizontally; and the side surfaces of the two ends of the upper chord tendons and the lower chord tendons are respectively wielded and fixed with vertical bars and the bottom parts of the vertical bars are welded and fixed on the template. The invention has the following beneficial effects that a plurality of inversed V-shaped web bars are used to replace corrugated web bars, thus the structure and manufacturing process are simple, the cost is low, the processing difficulty is small and the production effieciency is high. The strength, rigidity and shearing resistance of the template truss are greatly enhanced, and the combination property and bearing capacity of the template truss are improved.

Description

Simple bearing type template truss

Technical field

What the present invention relates to is template truss, particularly be simple bearing type template truss.

Background technology

Template truss is main structural members such as the floor, roof system, sole plate in the present multi-rise building.The structure of prior art template truss comprises: template, be weldingly fixed on a plurality of truss that are parallel to each other on the template.Described truss comprises: the muscle that winds up, lower edge muscle and abdomen muscle; The described muscle that winds up is one, is arranged on the truss top; Described lower edge muscle is symmetricly set on the muscle below of winding up, and described wind up muscle and lower edge muscle are positioned at three points of isosceles triangle at the cross section of truss; Described abdomen muscle is ripple type, is welded on the wind up muscle and the lower edge muscle of truss both sides.

There is following shortcoming in the template truss of above-mentioned prior art:

1. be ripple type owing to the abdomen muscle, the manufacturing process complexity, the equipment cost height, difficulty of processing is big, and production efficiency is low.

2. a plurality of truss that are parallel to each other are set on template, and no any connection between each truss exists the total bearing capacity of template truss poor.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of manufacturing process simple, cost is low, and each truss on the template is connected to each other as a whole, the simple bearing type template truss that bearing capacity is high

The technical scheme that solves the problems of the technologies described above is: a kind of simple bearing type template truss, and described simple bearing type template truss comprises: template, the muscle that winds up, lower edge muscle and abdomen muscle, described wind up muscle and lower edge muscle are parallel interval setting up and down; Tilt to be welded to form at the abdomen muscle of wind up muscle and lower edge muscle both sides first single abdomen muscle and second single abdomen muscle by a plurality of Λ of being types, the upper end of described first single abdomen muscle and second single abdomen muscle is wrapped up and is welded on the muscle that winds up respectively, the lower end of first single abdomen muscle and second single abdomen muscle is welded on lower edge muscle two rear flank respectively, and its extension bending is level and is weldingly fixed on the template; Be welded with montant respectively in wind up muscle and lower edge muscle side faces at both ends, described montant bottom is weldingly fixed on the template.

The invention has the beneficial effects as follows: the present invention overcomes the defective of prior art, the present invention substitutes the abdomen muscle of baroque ripple type in the prior art with two single abdomen muscle of a plurality of Λ types, and abdomen muscle structure of the present invention and manufacturing process are simple, at the bottom of the manufacturing cost, difficulty of processing is little, the production efficiency height.

A plurality of truss on the template truss cross section of the present invention, the welding of a plurality of truss is fixed as one and is fixed on the template with a plurality of single abdomen muscle, make the strength and stiffness and the shear behavior of template truss obtain strengthening significantly, improve resistance to compression, the shear resistance of template truss, improve the combination property of template truss, make it can bear bigger working load; The template truss good stability, the supporting capacity height.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.

Fig. 1 is a front view of the present invention; Fig. 2 is an A-A sectional view among Fig. 1; Fig. 3 is a partial perspective view among Fig. 1.

The invention provides a kind of simple bearing type template truss, described simple bearing type template truss comprises: template, the muscle that winds up, lower edge muscle and abdomen muscle.

Described wind up muscle 3a and lower edge muscle 3b are parallel interval setting up and down.

First single abdomen muscle 2a and second single abdomen muscle 2b by a plurality of Λ of being types tilts to be welded to form at the abdomen muscle of described wind up muscle 3a and lower edge muscle 3b both sides, be the both sides that the single abdomen muscle 2b of first single abdomen muscle 2a and second tilts to be welded on wind up muscle 3a and lower edge muscle 3b, and composition Λ type pattern, according to different size, can form a plurality of abdomen muscle that are the Λ type in the both sides of wind up muscle 3a and lower edge muscle 3b.

The upper end of described first single abdomen muscle 2a and second single abdomen muscle 2b is wrapped up respectively and is welded on and winds up on the muscle 3a, the lower end of first single abdomen muscle 2a and second single abdomen muscle 2b is welded on lower edge muscle 3b two rear flank respectively, and its extension bending is level and is weldingly fixed on the template 4.

Be welded with montant 1 respectively in wind up muscle 3a and lower edge muscle 3b side faces at both ends, described montant 1 bottom is weldingly fixed on the template 4.

As Fig. 2, shown in Figure 3, described template 4 is provided with a plurality of being parallel to each other and at interval wind up muscle 3a and lower edge muscle 3b, and the part that first the single abdomen muscle 2a on the cross section of described a plurality of wind up muscle 3a and lower edge muscle 3b and second single abdomen muscle 2b are weldingly fixed on the template 4 connects as one separately respectively and is welded on the template 4.

In particular, template 4 is provided with a plurality of being parallel to each other and wind up muscle 3a and lower edge muscle 3b at interval, and first the single abdomen muscle 2a on the cross section of described a plurality of wind up muscle 3a and lower edge muscle 3b interconnects; Second single abdomen muscle 2b on the cross section of described a plurality of wind up muscle 3a and lower edge muscle 3b interconnects, and a plurality of muscle 3a and lower edge muscle 3b and welding first single abdomen muscle 2a and second single abdomen muscle 2b thereon of winding up on the template 4 all are welded as a whole with template 4.
