Abstract
The utility model provides a pre-buried formula sleeve bolt. The pre-buried sleeve bolt is composed of a sleeve, a screw rod, an openable cover, a nut, a gasket and the like, when the pre-buried sleeve bolt is used, the pre-buried sleeve bolt is pre-buried in a specified position of a concrete member, and after the strength of concrete meets requirements, the openable cover is pulled open, the screw rod is pulled out, and the nut is screwed. The concrete member construction method has the advantages that secondary drilling and field welding are not needed on the concrete member, the damage effect of the drilling holes on the concrete member can be reduced, the working procedures are reduced, the potential safety hazard of construction is eliminated, the safety and the durability of the concrete member are improved, and the reliability of connection between the building auxiliary member and the main body structure is improved.
Description
Technical Field
The utility model belongs to the technical field of the building, particularly, relate to a pre-buried formula sleeve bolt.
Background
A large number of accessory components are required to be connected with a main body structure in the processes of electromechanical installation, curtain wall and stone construction and indoor and outdoor decoration of a building, and most of the existing connection modes are realized by adopting embedded parts or post-planted expansion bolts and chemical bolts. The embedded part is troublesome to construct because welding is needed in later construction, belongs to open fire operation and has larger potential safety hazard; the post-planted expansion bolt or chemical bolt is troublesome in construction and has certain damage to the main structure due to secondary hole forming in the main structure, and potential safety hazards also exist. The utility model overcomes prior art's is not enough, discloses a pre-buried formula sleeve bolt, uses pre-buried formula sleeve bolt not to need on-the-spot welding and concrete member secondary pore-forming, can accomplish building additional member and major structure's being connected, makes the work progress become more safe, convenient and high-efficient.
SUMMERY OF THE UTILITY MODEL
The utility model provides a pre-buried formula sleeve bolt aims at solving among the prior art the above-mentioned problem that building auxiliary member and major structure are connected.
The utility model discloses a realize like this: a pre-embedded sleeve bolt comprises a sleeve (1), a screw (2), an openable cover (3), a nut (4), a gasket (5) and the like.
The sleeve (1) has one end closed and the other end connected with the openable cover (3), and the sleeve is internally of a wedge-shaped structure or a straight cylinder structure with a thickened opening end.
The screw rod (2) is nested in the sleeve (1), the tail part of the screw rod is a conical structure expansion head (7) or a thickened expansion head (8), the length of the screw rod is smaller than that of the sleeve, and the diameter of the screw rod is smaller than the inner diameter of the sleeve.
The opening end of the sleeve is connected with an openable cover (3), the whole length of the screw rod is positioned in the sleeve when the openable cover is closed, and the screw rod screw thread end (6) can be pulled out when the openable cover is opened.
One end of the screw rod, which can be pulled out, is provided with a screw thread (6), and the nut (4) and the gasket (5) are screwed on the screw rod, so that the connection between the accessory component and the main structure can be realized.
The utility model has the advantages that: when the embedded sleeve bolt is used, the embedded sleeve bolt is embedded at the designated position of a concrete member, after the concrete strength meets the requirement, the openable cover (3) is opened, the screw rod (2) is pulled out, and the nut (4) is screwed, so that secondary drilling and field welding on the concrete member are not needed, the connection of the building auxiliary member and a main structure can be completed, the construction process is safer, more convenient and more efficient, the damage to the concrete member is reduced, the processes are reduced, the construction potential safety hazard is eliminated, the safety degree and the durability of the concrete member are improved, and the reliability of the connection of the building auxiliary member and the main structure is improved.
