A heavy-duty full hall formwork support system

Abstract

The invention provides a heavy load full formwork support system, which comprises a plurality of vertical rods and a plurality of horizontal rods, wherein each vertical rod consists of a steel pipe, circular end plates, an enhancing sleeve pipe, a fixing inserting groove and a sliding inserting groove, each steel pipe has certain length modulus, the circular end plates are fixedly arranged at the two ends of the corresponding steel pipe, a bolt hole is formed in each circular end plate, each enhancing sleeve pipe is welded at the connecting part of the vertical rods and the horizontal rods, each fixing inserting groove is welded at one side of the corresponding enhancing sleeve pipe, each sliding inserting groove is positioned between the corresponding circular end surface and the corresponding fixing inserting groove, and can slide along the corresponding vertical rod, each fixing inserting groove and each sliding inserting groove respectively comprise four inserting grooves, the inserting grooves are uniformly, vertically and correspondingly arranged along the annular direction, and are used for connecting the four longitudinal and transverse horizontal roads, each horizontal rod consists of a steel pipe and two inserting plate, each inserting plate is arranged at the end part of the corresponding steel pipe, and each inserting groove is matched with the corresponding inserting plate at the end part of the corresponding horizontal rod. The heavy load full formwork support system has the advantages that the safety and reliability are realized, the building is convenient and rapid, and the bearing capability is high.

Description

technical field [0001] The invention relates to a temporary support structure for civil engineering construction, and more specifically relates to a novel heavy-duty full hall formwork support system. Background technique [0002] my country's infrastructure construction is in a period of rapid development, the scale of civil engineering is getting larger and larger, and more and more temporary support structures are used as auxiliary facilities, especially the heavy-duty temporary support structures used in subway and bridge construction. At present, there are three types of temporary support structures commonly used in engineering: fastener type, bowl button type and socket type. During the use of the above three supporting structures, some shortcomings are exposed: [0003] 1) Although the fastener-type steel pipes are flexible in erection and removal, the quality and tightening torque of the fasteners have a significant impact on the bearing capacity of the fastener-typ...

AI Technical Summary

Problems solved by technology

[0003] 1) Although the fastener-type steel pipes are flexible in erection and removal, the quality and tightening torque of the fasteners have a significant impact on the bearing capacity of the fastener-type steel pipe support structure, and it is difficult to control the torque and quality of the fasteners in the actual application process, resulting in erection defects. It reduces the structural bearing capacity and induces engineering accidents from time to time; secondly, the fastener nodes are easy to lose, which increases the construction cost;

[0004] 2) The joint stiffness of the bowl-button and socket-type steel pipe support structures is much higher than that of the fastener type, but the joint stiffness is still weak, especially the bending bearing capacity of the joints is weak; heavy loads can easily lead to serious plasticity in the joint area Deformation and dents, reducing the durability and safety of components
