Building steel connecting piece high-temperature structural strength testing device

Abstract

The invention discloses a building steel connecting piece high-temperature structural strength testing device which comprises a base, two symmetrical supporting blocks are fixed to the base, motors are fixed to the two supporting blocks, shaft rods are fixed to output shafts of the motors, power blocks are connected to the shaft rods in a threaded mode, and sliding blocks are fixed to one sides ofthe power blocks. And a semicircular curved bar is arranged in each sliding block in a sliding mode, supports are fixed to the two ends of the curved bars correspondingly, a pressure block is fixed between the two supports, a clamping block is fixed to the pressure block, and two symmetrical hydraulic cylinders are arranged on the clamping block. The invention relates to the technical field of buildings. According to the high-temperature structural strength testing device for the building steel connecting piece, the problems that an existing testing device for the steel connecting piece is single in testing structure, stress testing cannot be conducted on the steel connecting piece in multiple directions, and testing data of the steel connecting piece are affected are solved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a high-temperature structural strength testing device for construction steel connectors. Background technique [0002] Reinforcement connection refers to the connection method of steel bars. The connection methods of steel bars mainly include binding lap joint, mechanical connection, casing grouting connection and welding. The key parts of the seismic design should avoid the encrypted range of stirrups at the beam end and column end, and if they must be connected in this area, mechanical connection or welding should be used. [0003] With the development of construction, the requirements for the production of steel cages are getting higher and higher. The new requirements cannot be completed by hand. It is advisable to set fewer connection joints on the same stressed steel bars in the same span or in the same floor height. It is necessary to improve the connection. The stre...
