Description

Technical Field

[0001] The utility model relates to the technical field of anchor bolts, in particular to a screw anchor bolt with good fixing effect. Background Art

[0002] Anchor bolts are a new type of metal fastening material. They can be used for the installation of embedded parts in various curtain walls and marble dry hanging construction, as well as for equipment installation, highway and bridge guardrail installation; building reinforcement and renovation and other occasions. Because the chemical reagents in the glass tube are flammable and explosive, the manufacturer must obtain approval from the relevant national departments before production. The entire production process requires strict safety measures and the use of assembly lines that are completely isolated from the staff. Anchor bolts can be divided into two types according to their scope of application. Anchor bolts suitable for cracked concrete and non-cracked concrete can be divided into two categories according to their working principles: expansion anchor bolts, expanded bottom anchor bolts and chemical anchor bolts. Chemical anchor bolts are a new type of anchor bolt that appeared after the expansion anchor bolt. They are composite parts that use special chemical adhesives to bond the screws to the drilled holes in the concrete substrate to achieve anchoring of the fixings.

[0003] However, in the existing equipment, when the anchor bolt is used, the chemical agent is first placed in the hole, one end is placed in the hole, and the chemical agent is chiseled, and then the chemical anchor bolt is screwed into the hole so that the glue and stone in the chemical agent are bonded to the thread. Since the fragments of the chemical agent bottle remain in the hole, the firmness of the shaft rod and the chemical agent will be affected. Therefore, a screw anchor bolt with good fixing effect is proposed. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a screw anchor bolt with good fixing effect.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a screw anchor bolt with good fixing effect, comprising an anchor rod, a mounting hole is provided on the anchor rod, a first end head is fixedly provided at the bottom of the anchor rod, a threaded rod is movably provided in the mounting hole, a hexagonal column head is fixedly provided at the top of the threaded rod, a second end head is fixedly provided at the bottom of the threaded rod, a gasket is sleeved on the anchor rod, and a nut is movably provided on the anchor rod.

[0007] The inner wall of the mounting hole is provided with an internal thread, and the threaded rod is matched with the internal thread of the inner wall of the mounting hole.

[0008] As a further description of the above technical solution:

[0009] The thickness of the gasket is three millimeters and the gasket is made of stainless steel.

[0010] As a further description of the above technical solution:

[0011] Two groups of leakage holes are arranged on the outside of the anchor rod, the inner diameter of the leakage holes is eight millimeters, and the leakage holes are located at the lower part of the anchor rod.

[0013] The first end head is provided with a cavity, and the second end head is adapted to the cavity provided in the first end head.

[0014] As a further description of the above technical solution:

[0015] The first end and the second end are both conical, and a liquid outlet is provided on the inner wall of the bottom of the first end.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the screw anchor with good fixing effect is provided with leakage holes, liquid outlet holes and mounting holes. When in use, the anchor rod is placed in the drilled hole, and then the chemical reagent is poured into the mounting hole. The chemical reagent is discharged into the hole through the multiple leakage holes on the anchor rod and the liquid outlet hole at the bottom of the first end. There is no need to place the chemical bottle in the hole and break the bottle, thereby avoiding the bottle fragments remaining in the hole and ensuring the adhesion strength of the shaft rod and the chemical agent.

[0018] 2. Compared with the prior art, the screw anchor with good fixing effect is provided with a threaded rod, a hexagonal column head and a second end head. After the agent is introduced into the installation hole, the threaded rod is inserted into the installation hole and the sleeve at the output end of the wrench is clamped on the hexagonal column head and rotated clockwise. The threaded rod drives the second end head to move downward. When the second end head enters the cavity of the first end head and fits with the inner wall of the first end head, the rotation of the hexagonal column head is stopped. The setting of the threaded rod can not only squeeze out the chemical agent in the installation hole, but also fill the installation hole, thereby improving the overall strength of the anchor bolt.
