Embodiment Construction

[0021] The core of the present invention is to provide a split bolt, which solves the problem that the nut is not firmly reinforced, and also greatly improves the installation efficiency of the split bolt and reduces the reinforcement time.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a tension bolt provided in a specific embodiment of the present invention.

[0024] In a specific embodiment, the pull bolt provided by ...

Abstract

The invention discloses a split bolt. The split bolt comprises a screw rod (1), two opposite butterfly clamps (2) and a limiting insert (3), wherein the screw rod (1) is sleeved with the two oppositebutterfly clamps (2) through holes, and limiting holes are formed in the positions, on the outer sides of the butterfly clamps (2), of the screw rod (1); and the limiting insert (3) can be inserted into the limiting holes and positioned, and the outer side faces of the butterfly clamps (2) abut against the inner side face of the limiting insert (3). By the adoption of the technical scheme, the butterfly clamps are positioned on the screw rod without nuts, the limiting holes are formed in the screw rod, the limiting insert is used for reinforcement, the connecting mode that the limiting insertis inserted into the limiting holes is not affected even after the screw rod is rusted after multiple times of turnover, the problem that nut reinforcement is not firm is solved, and the phenomenon ofmold shifting is avoided; and meanwhile, the installation efficiency of the split bolt is greatly improved, and the reinforcement time is shortened.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a tension bolt. Background technique [0002] Pull bolts, also known as pull screws, are used for the tie between the inner and outer formwork in the wall, and bear the lateral pressure and other loads of the concrete to ensure that the distance between the inner and outer formwork can meet the design requirements. It is also the formwork and its support. The fulcrum of the structure. Therefore, the arrangement of the tension bolts has a great influence on the integrity, rigidity and strength of the formwork structure. [0003] At present, the corrosion of the screw rod after multiple turnovers of ordinary tie bolts will make the connection between the screw rod and the nut weak, which will cause the problem of running molds, reduce the installation efficiency of the tie bolts, and take a long time for reinforcement. [0004] To sum up, how to effectively solve th...
