Abstract

The utility model provides a wood-and-steel composite truss, comprising ramp beams, raking struts, posts and upward cross beams. One end of each of the two ramp beams is permanently connected, the other end is correspondingly connected to both ends of the cross beam; a post is permanently connected between the point of two ramp beams and a cross beam; a flat steel perpendicular with the cross beam is fixed at the connection end of the ramp beam and the cross beam. The utility model is characterized in that the cross beam is composed of two steel bars, and a plurality of horizontal tie-rod plates are arranged between the two steel bars; a plurality of additional tie-rods are put through the tie-rod plate and the ramp beam, and both ends are fixed by nuts; raking struts are the upper and lower ends of two neighboring tie-rods or a post and a neighboring tie-rod; the triangle steel at the side where the bottom faces the post is permanently connected to the tie-rod plate; triangle steel plates are arranged at both sides of the flat steel along the direction of the cross beam, and respectively connected to the ramp beam and cross beam permanently. The utility model adopts two steel bars as a cross beam; the nuts at both ends of a tie-rod are permanently connected with the ramp beam and the cross beam. The utility model has the advantages of large span, high strength and less failure.

Description

Steel wood room frame

Affiliated technical field

The utility model provides a kind of steel wood room frame, belongs to joist technical field for building.

Background technology

In building construction, the room frame is a critical component, and it requires to have certain intensity and rigidity.The roof on pinnacles such as existing house owed by a citizen, factory building mostly is wooden room and sets a roof beam in place, defective is limit by material, corrosion-resistant, usually use and just began in several years to be damaged gradually by aqueous vapor, insect corrosion, and the restriction of the length of being drawn materials, room frame crossbeam is usually played the tenon butt joint with two wood, and the firm degree of tie point is poor, the requirement of incompatibility large span; Have small part cement room to set a roof beam in place, quality is heavy, and lifting is difficult for, and also exists cement spare to connect unstable problem; Also there is the room of welding to set a roof beam in place, as Chinese patent communique disclosed utility model patent on June 1st, 1994: a kind of novel roof truss beam, the patent No.: 93216410, formed by cant beam, crossbeam, reinforcing rib, diagonal brace.Each end of two cant beams interconnects the composition triangle, and the crossbeam two ends are connected with the other end of cant beam respectively, and the three forms the sealing triangle, and reinforcing rib vertically is fixed between cant beam, the crossbeam, and diagonal brace places on the upper/lower terminal of two adjacent reinforcing ribs.The utility model unique distinction is that crossbeam is the radian that is bent upwards, because crossbeam is upwards arc, so pressure is to the dispersion of crossbeam two end supports point, therefore whole roof truss load bearing beam ability height.Because this roof truss beam adopts metal material, each phase contact electricity consumption weldering, therefore whole roof truss beam forms integral body.Reinforcing rib supports and is welded between cant beam, the crossbeam, but weld is easy to crack, has influenced application life.Along with the raising of industrial expansion, people's living standard, the span on roof is increasing, and is also more and more higher to the quality requirement of room frame, and sets a roof beam in place and can not satisfy the demand of development in above-mentioned room.

The utility model content

The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, have that span is big, intensity is high, the steel wood room frame of easy fracture characteristics not.Its technology contents is:

Comprise cant beam, diagonal brace, column, band steel and the crossbeam that is the arc that makes progress, wherein an end of two cant beams is fixedly connected, the other end corresponding with the crossbeam two ends isosceles triangle that is composed of a fixed connection, column is fixedly connected between two cant beam tie points and the crossbeam mid point, the end that is connected at cant beam and crossbeam is fixed with band steel with beam vertical, it is characterized in that: crossbeam is two reinforcing bars, between be fixed with the draw-bar guide of multiple tracks level, guarantee that the room frame has big span, set up the multiple tracks pull bar and pass draw-bar guide and cant beam vertically upward, its two ends are fixed through nut, diagonal brace place two adjacent pull bars or column and adjacent pull bar on, on the following two ends, its bottom is provided with three angle steel towards stud sides and fixedlys connected with draw-bar guide, set up triangular steel plate in the band steel both sides along the crossbeam direction, respectively with cant beam, crossbeam is fixedly connected, in order to reinforce being connected of cant beam and crossbeam.

Described steel wood room frame is fixed with steel plate in the junction of column and cant beam, crossbeam.

Described steel wood room frame, setting up triangular steel plate in the band steel both sides along the crossbeam direction is the right-angled triangle steel plate, its two right-angle side is fixedlyed connected with band steel, crossbeam respectively.

The utility model compared with prior art, crossbeam adopts the draw-bar guide that is fixed with the multiple tracks level between two reinforcing bars to form, guarantee that the room frame has big span, not limited by material, its two ends of the pull bar of setting up are fixed through nut and cant beam, crossbeam, overcome original technology and adopted reinforcing rib welding support fixation defective easy to crack, set up the fixedly fastness that triangular steel plate has strengthened cant beam and crossbeam especially in the band steel both sides along the crossbeam direction, have that span is big, intensity is high, advantage such as easy fracture not, be comparatively desirable joist for building at present.
