Abstract
Description
Technical Field
[0001] The invention relates to the technical field of construction engineering, and in particular to a steel tie rod quick connection structure and a connection method. Background Art
[0002] Steel tie rod products are widely used in building structure projects. Due to the limited length of domestic round steel bars, the rod body of steel tie rod products often needs to be extended. At present, the rod body of steel tie rods is basically connected and lengthened with threaded sleeves. The traditional steel tie rod body adopts threaded connection. Threaded connection requires the axial horizontal movement of the rod body and the axial rotation of the connector to cooperate with each other to realize the connection function. There are certain requirements for the operating space around the steel tie rod products. Basically, the overall hoisting and installation are completed after the ground connection is completed. For specifications with large deadweight and limited space, it is more difficult to hoist and install steel tie rods. At the same time, due to the small gap of the threaded connection, it is difficult to set anti-corrosion measures on the thread surface, which cannot meet the anti-corrosion performance requirements of the steel tie rod. In actual use, the thread part often rusts, which makes the steel tie rod cause structural instability and form a safety hazard. In addition, the installation method of threaded connection requires a rotating sleeve, which requires a certain operating space, and the construction is extremely difficult. Summary of the invention
[0003] In order to solve the technical problems mentioned in the background technology, the present invention provides a steel pull rod quick connection structure and a connection method.
[0004] The present invention adopts the following technical scheme: a steel pull rod quick connection structure, comprising a steel pull rod connecting rod body A, a steel pull rod connecting rod body B and a detachable sleeve fixed between the steel pull rod connecting rod body A and the steel pull rod connecting rod body B; the detachable sleeve tube comprises two upper and lower semicircular sleeves A and semicircular sleeves B; the semicircular sleeves A and semicircular sleeves B are aligned and fixedly connected together by at least one pair of left and right fixed long bolts that penetrate from the side of the shell from top to bottom; the centers of the semicircular sleeves A and semicircular sleeves B are both provided with semicircular arc-shaped smooth grooves; the ports of the semicircular arc-shaped smooth grooves are inverted cones; the outer edges of the semicircular sleeves A and semicircular sleeves B are provided with mating clamping protrusions and clamping grooves; the steel pull rod connecting rod body A and the steel pull rod connecting rod body B are provided with upsetting to form circular bosses C and circular bosses D; the circular bosses C and circular bosses D are relatively arranged and clamped in the semicircular arc-shaped smooth grooves.
[0005] Furthermore, the distance between the circular bosses is maintained at 1-2 mm.
[0006] Furthermore, the inner and outer surfaces of the detachable sleeve are coated with anti-corrosion materials.
[0007] Furthermore, the present invention also provides a connection method for the above-mentioned steel tie rod quick connection structure, comprising the following steps: forging and upsetting the end of the steel tie rod connecting rod body to form a circular boss; adjusting the two steel tie rod connecting rod bodies and the rod bodies to be connected to appropriate positions in the semicircular sleeve; snapping a pair of semicircular sleeves from both sides of the rod body; and fixing the two by inserting a pair of semicircular sleeves through a fixed long bolt.
[0008] Compared with the prior art, the advantages of the present invention are: the steel tie rod quick connection structure designed by the present invention realizes the connection and lengthening of the steel tie rod body by forging bosses at both ends of the steel tie rod body and then fastening and fixing two semicircular sleeves from both sides. This structure abandons the method of threaded connection and lengthening, and does not need to rotate the fixed sleeve for fixing. When connecting, it does not require the axial horizontal movement of the rod body and the axial movement of the connector. It is not limited by space, and the extension and installation of the steel tie rod can be completed in a very small space. The installation difficulty is extremely low, and the rod body can be quickly connected. When the steel tie rod product specifications and self-weight are large, it can be hoisted and installed in sections multiple times. This structure can be coated with an anti-corrosion layer on the connection part, which greatly improves the durability of the connection of the steel tie rod product.
