Pre-embedded fixing device and using method

Abstract

The invention relates to the technical field of installation, and particularly discloses a pre-embedded fixing device and a using method. The pre-embedded fixing device comprises a hollow steel pipe,wherein an internal thread is arranged inside the hollow steel pipe, one end of a screw rod matched with the internal thread is in threaded connection with the hollow steel pipe, the other end of thescrew rod is connected with a fastener, the hollow steel pipe is embedded in the ground, the periphery of the hollow steel pipe is subjected to pouring and fixed to the ground, and the fastener is matched with the ground to compress equipment. The hollow steel pipe is used for reinforcing stress between the hollow steel pipe and the ground, the requirement for the rigidity and strength of the ground is low, fixing and detaching are convenient through the movable screw rod, and different stress can be provided.

Description

technical field [0001] The invention relates to the technical field of equipment installation, in particular to a pre-embedded fixing device and a using method. Background technique [0002] Anchor bolts and expansion screws are important fixing methods for equipment installation. This kind of fixing method is either after the ground is drilled, and the anchor bolts or expansion screws are driven into the fixing holes in the ground; or the screw and the concrete foundation are poured into an integrated structure. . [0003] For the method of drilling holes in the ground to drive anchor bolts or expansion screws into the fixing holes, the rigidity of the ground is required to be high. The force of the anchor bolts and expansion screws themselves is not large enough, and the fixed size cannot be changed according to special needs. For the method of pouring the screw and the concrete foundation as one, if the screw of the anchor bolt breaks, the equipment needs to be shut down...

Problems solved by technology

[0003] For the method of drilling holes in the ground to drive anchor bolts or expansion screws into the fixing holes, the rigidity of the ground is required to be high. The force of the anchor bolts and expansion screws themselves is not large enough, and the fixed size cannot be changed according to special needs.

For the method of pouring the screw and the concrete foundation as one, if the screw of the anchor bolt breaks, the equipment needs to be shut down to replace the screw for maintenance. When replacing, first, the equipment needs to be hoisted as a whole, and then the concrete foundation can only be replaced after being removed. Finally, the concrete foundation is remade; the whole replacement process is complicated and requires other equipment to complete the replacement, which is time-consuming, labor-intensive, inefficient, and the concrete foundation needs to be remade, the labor intensity of the workers is high, and the maintenance cost is high
