Problems solved by technology

In bridge construction, cantilever embedded brackets are often used. When universal rods are used as cantilever brackets, the safety and reliability of the embedded nodes are difficult to be guaranteed due to the complex force of the embedded nodes and high positioning accuracy requirements. It will affect the appearance of concrete, and the positioning accuracy of the pre-embedded joints of the existing universal rods is not high, which cannot meet the construction requirements

Abstract

The invention relates to a universal member pre-buried node. The universal member pre-buried node comprises a node plate, a plurality of screw rods and a plurality of locking bolts which are respectively in matching connection with the plurality of screw rods, wherein one end of each screw rod is provided with an inside thread, a plurality of via holes are formed in a locating steel plate, the plurality of screw rods respectively penetrate through the via holes in the locating steel plate and are welded with the locating steel plate together to be commonly pre-buried in concrete, the node plate is in a T shape and consists of a vertical straight plate and a horizontal straight plate, a plurality of first bolt holes for splicing a universal member are formed in the vertical straight plate, and a plurality of second bolt holes are formed in the horizontal straight plate, are correspondingly matched with the plurality of screw rods one by one and are respectively connected and fixed with a screw rod through a spring washer and a locking bolt. According to the universal member pre-buried node disclosed by the invention, the screw rods are stressed, a force transmission route is definite and reasonable, the stress performance is good, the safety and reliability are high, and the appearance of concrete can also be ensured without influence.

Description

technical field [0001] The invention relates to a node combined with a universal rod and concrete, in particular to a pre-embedded node of a universal rod and an installation method thereof. Background technique [0002] Universal rod is a kind of construction equipment widely used in engineering construction. It can be assembled arbitrarily according to the needs of construction, such as: simple lining trolley, gantry crane, conveying tower, platform and other load-bearing support structures, and it is easy to master and use. Because the universal rod has the characteristics of flexible structure, high bearing capacity and low cost of use, it is widely used in building construction. In bridge construction, cantilever embedded brackets are often used. When universal rods are used as cantilever brackets, the safety and reliability of the embedded nodes are difficult to be guaranteed due to the complex force of the embedded nodes and high positioning accuracy requirements. It...
