Segmental assembled prestressed steel-wood combined truss rod piece and mounting method thereof

Abstract

The invention relates to a segmental assembled prestressed steel-wood combined truss rod piece. The segmental assembled prestressed steel-wood combined truss rod piece comprises a plurality of wood rod piece segments, prestressed threaded steel bars, end shear-resistant anchoring iron nails and end steel connecting pieces, wherein flanges and notches are respectively arranged on the head and tail ends of the wood rod piece segments, and through round holes are formed in the middle of the wood rod piece segments; the prestressed threaded steel bars sequentially penetrate through the wood rod piece segments, and the adjacent wood rod piece segments are tightly buckled through the flanges and the notches to form a long-strip-shaped rod piece; through holes are formed in the middle of the end steel connecting pieces, the two ends of the long-strip-shaped rod piece respectively penetrate through the end steel connecting pieces, and the end steel connecting pieces make contact with the wood rod piece segments on the head and tail ends correspondingly and are locked through end anchoring nuts which are matched with the prestressed threaded steel bars; and the end steel connecting pieces are fixedly connected with the wood rod piece segments through the end shear-resistant anchoring iron nails. The segmental assembled prestressed steel-wood combined truss rod piece has the advantages of large section rigidity and good mechanical properties and can bear tension and pressure at the same time, and zero carbon emission of the whole component can be achieved.

Description

technical field [0001] The invention belongs to the technical field of steel-wood composite structure design, in particular to a segmentally assembled prestressed steel-wood composite truss member and an installation method thereof. Background technique [0002] With the continuous development of the national economy, the construction industry has become one of the pillar industries of our country, but the commonly used building materials in the construction industry - steel and cement generally have the problem of high carbon emissions and are not green. With the goal proposed, green and low-carbon has become the mainstream trend of technological development in the field of engineering construction. The scope of use of high-strength building materials and green building materials is gradually expanding. As a typical green building material, wooden structures are produced in a carbon sequestration process (ie, negative carbon emissions). Moreover, wooden structures are light...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a segmentally assembled prestressed steel-wood composite truss member and its installation method in view of the deficiency that the steel-wood composite truss web members in the above-mentioned prior art cannot bear pressure. The section of the truss member has a large rigidity, can bear tension and pressure at the same time, has better mechanical properties, and can also achieve zero carbon emission of the overall component
