Embedded lower chord member propeller strut web member assembly type truss

Abstract

The invention relates to an embedded lower chord member propeller strut web member assembly type truss. The assembly type truss comprises an upper chord member, propeller strut web members and embedded lower chord members, the propeller strut web members are arranged above the embedded lower chord members, the tail ends of propeller struts wrap the embedded lower chord members and are connected with the lower chord members, the upper chord member is flatly laid above the propeller strut web member and is connected with the propeller strut web member, and the propeller strut web member comprises at least two prefabricated propeller struts and is assembled by taking a single propeller strut as a basic unit. According to the embedded lower chord member propeller strut web member assembly type truss, the method of split prefabrication and field assembly is adopted, transportation and storage yard storage are facilitated, cost is saved, convenience is improved, the construction period is greatly shortened, economic benefits are brought, wide application prospects are achieved, and the development of an assembly type structure is greatly promoted.

Description

technical field [0001] The invention relates to the technical field of concrete structures in civil engineering, in particular to an assembled truss, in particular to an embedded lower chord herringbone web assembled truss. Background technique [0002] Prefabricated concrete structure has become an irreplaceable technology and structural form in the construction industry. The production and production of prefabricated concrete components occupy an important position. Truss is a commonly used structural form. Prefabricated concrete trusses are used as buildings, roof structures and bridges. Structures, etc. have been widely used in engineering. However, the overall prefabricated concrete truss not only takes up a lot of space due to its huge external dimensions, but is often produced on site due to transportation restrictions, and the storage space required for the overall prefabrication of the truss, as well as the complex reinforcement of the truss and the complex mold sys...

AI Technical Summary

Problems solved by technology

However, the overall prefabricated concrete truss not only takes up a lot of space due to its huge external dimensions, but is often produced on site due to transportation restrictions, and the storage space required for the overall prefabrication of the truss, as well as the complex reinforcement of the truss and the complex mold system Both the cost and the high cost make this process flawed. Even compared with the solid beam, the saving of the truss material is offset by the cumbersomeness caused by the cost of the mold and the complex reinforcement.

In addition, when the span of the truss is large, the on-site open-air cast-in-place production is also affected by factors such as typhoon, heavy rain, and low temperature weather, which also affect the progress

Practice has proved that as a traditional construction method of overall prefabrication, trusses affect the construction period and cost, resulting in an increase in construction period costs, and it is difficult to reflect the advantages of prefabricated structures
