A prefabricated concrete truss building structure

Abstract

The invention discloses an assembled concrete truss building structure, which includes concrete prefabricated slabs arranged between building bodies, and a truss reinforcement structure is installed directly below the connection between the concrete prefabricated slab and the building body, and the truss reinforcement structures are arranged in order from top to bottom It is equipped with a partial pressure support mechanism, a support main board, a support structure and a pressure-bearing side plate located at the inner end of the support structure. The partial pressure support mechanism includes several groups of anchor rods prefabricated at the bottom of the concrete prefabricated slab, and the bottom of each group of four anchor rods is fixed. There is a pressure-dividing support frame, and a through groove is formed in the middle part of the pressure-dividing support frame, and longitudinal plates are interspersed between several groups of through grooves, and a horizontal plate is arranged directly below the longitudinal plate. The present invention supports the concrete truss structure for the building body and the suspended part outside the building body, and the assembled structure for effectively dispersing the pressure of the supporting object is used in the structure, and the applied pressure is evenly distributed in each position of the lower supporting main board , and cooperate with multiple sets of triangular structures to effectively improve the stability of the connection.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to an assembled concrete truss building structure. Background technique [0002] Reinforced Concrete Truss A truss made of reinforced concrete or prestressed concrete material. Reinforced concrete trusses are mostly used for roof trusses, towers, and sometimes trestles and crane beams. Because the tie rods of reinforced concrete trusses often crack under the load, they are only used for trusses with light loads and small spans. After the 1950s, with the development of prestressed concrete technology, prestressed concrete trusses have been widely used in China for trusses with large spans and heavy loads. The commonly used spans are 18, 24, and 30 meters, and some are 60 meters. For some suspended building structures installed on the periphery of buildings, such as small bridges suspended between buildings, special concrete truss structures need to be installed and fixe...

Problems solved by technology

[0003] However, the existing concrete truss structures used for supporting suspended building structures have the following problems: (1) the structure is simple and generally fixed and installed by concrete slabs and steel structures, and its pressure bearing capacity is small; (2) the suspended structure When the pressure on the surface of the building body is high, it is easy to cause structural damage on the surface of the building body at that place, resulting in potential safety hazards
