Inverted-V-shaped beam sequence structure made of honeycomb materials and purlin-free and girder-free roof truss structure formed by inverted-V-shaped beam sequence structures

Abstract

The invention provides an inverted-V-shaped beam sequence structure made of honeycomb materials and purlin-free and girder-free roof truss structure formed by inverted-V-shaped beam sequence structures. Light inverted-V-shaped beams which are prefabricated through light structural-net ribbed honeycombed concrete structures are used as core components of the inverted-V-shaped beam sequence structure, and a purlin-girder structure of a traditional technique is replaced. The inverted-V-shaped beam sequence structure made of the honeycomb materials is composed of the multiple inverted-V-shaped beams which are prefabricated through the structural-net ribbed honeycombed concrete structures, wherein each inverted-V-shaped beam is provided with two oblique side edges which are obliquely arranged downwards on the two sides of the peak and an arc-shaped lower edge which is located on the bottom side of the inverted-V-shaped beam, and two supporting legs which are used for being erected on a trimming beam and matched with the trimming surface of the trimming beam are arranged on the two endpoints, extending outwards, of each inverted-V-shaped beam; the inverted-V-shaped beams constituting the sequence structure are spaced from one another by the distance allowing a roof board to be erected directly; and inverted-V-shaped beam sequence structure made of the honeycomb materials is particularly suitable for constructing roof trusses of corridor type buildings or residential buildings or workshops. In this way, the construction process needing field construction in the prior art is completed through prefabrication in a factory, so that field construction is made easier, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a building structure, in particular to a honeycomb material girder sequence structure and a purlin-free roof truss structure formed therefrom. Background technique [0002] The traditional roof truss structure combined with purlins and trusses is used in typical oriental building structures. It forms a load-bearing roof truss by erecting truss beams on the top of the building’s load-bearing columns, and then uses purlins to make the roof truss strong and stable as a whole. The purlins also serve as roof supports. beam. Typical structure and construction process such as Chinese Patent Application Publication No. CN102936966A discloses a steel frame roof protection structure of a single-layer hard mountain purlin masonry house. The original roof is provided with roof purlins, and additional transverse steel beams, additional Longitudinal steel beams, steel columns, external foundations, roof truss beams and at least two inclined...

AI Technical Summary

Problems solved by technology

However, the roof truss beams are still welded with metal materials to form a whole, and there are still defects such as complicated process and excessive weight, so it is necessary to reduce the amount of use and carry out the integral connection of the entire roof truss through purlins
