specific Embodiment approach

[0019] Such as Figure 1~2 Shown, the specific embodiment of the present invention is as follows:

[0020] An A-shaped roof truss steel rod structure system, the A-shaped roof truss is a steel roof truss, including square steel beams arranged obliquely on both sides, lateral supports arranged in the middle, and supports arranged under the ends of the square steel beams. The connecting steel plates 2 are welded on both sides of the square steel beam of the seat, and the stiffening steel plates 3 of 60mm×40mm×6mm are respectively welded on both sides of the connecting steel plate 2 and the support. Vertical welding; a steel tie rod 1 is welded on the connecting steel plates 2 at both ends of the A-shaped roof truss, and the two steel tie rods 1 are connected by M22 turnbuckle bolts 6 .

[0021] The specific construction method is:

[0022] (1) When the A-shaped roof truss is arranged on the roof, the end support of the square steel beam is connected to the horizontal beam with...

Abstract

The invention relates to an A-shaped roof truss steel rod structure system and a construction method of theA-shaped roof truss steel rod structure system. The A-shaped roof truss steel rod structure system belongs to the field of an optimal design of a structure, and is suitable for a 'flat-to-slope' application of an old house. An A-shaped roof truss is a steel roof truss and comprises a square steel beam, a transverse support and a support; connection steel plates are respectively welded at two sides of the square steel beam at the support; reinforced steel plates are respectively welded at two sides of the connection steel plates and the support; the reinforced steel plates are vertically welded with the square steel beam, the connection steel plates and the support respectively; a steel rod is welded on the connection steel plates at each of two ends of the A-shaped roof truss; and two steel rods are connected by a flower basket bolt. According to the structure system and the method disclosed by the invention, stability of the roof truss is improved by arranging the steel rods at the bottom of the A-shaped roof truss; the advantages of less steel amount of the A-shaped roof truss in a traditional method are adopted; entire stability of a steel frame is increased, and the A-shaped roof truss steel rod structure system is economic and reasonable, safe and reliable, and has a wide application prospect.

Description

technical field [0001] The invention relates to a roof truss structure system, in particular to an A-shaped roof truss steel tie rod structure system and a construction method thereof, belonging to the field of structural optimization design. Background technique [0002] The renovation of multi-storey buildings started in Beijing in 2002 and has been going on for ten years. In order to standardize the actual implementation plan, two documents were issued in 2006, the "Beijing Structural Technical Implementation Outline of Level-to-Slope Conversion Project" and "Beijing Reference Atlas of Level-to-Slope Building Structure (Trial)". According to the comprehensive consideration of practical experience, the A-shaped roof truss is widely used in practical engineering because of its relatively small amount of useful steel, which can be assembled in the factory, a single roof truss is light in weight, easy to transport vertically, and less wet work. However, this roof truss also ...
