Description

Rear anchoring chemical internal thread type inverted cone sleeve

Technical Field

The utility model belongs to the technical field of fasteners, and particularly relates to a rear anchoring chemical internal thread type inverted cone sleeve.

Background

In the prior art, if a concrete installation device or apparatus is needed, a sleeve is pre-buried on a concrete slab, and the sleeve and a bolt are matched for installation and fixation. While the traditional chemical anchor bolt has the advantages of simple installation, high tensile strength and the like, the integrated anchor bolt structure makes the adhesive difficult to uniformly contact and distribute with the concrete, and influences the shearing resistance and the tensile strength of the adhesive. The planar structure of conventional hex nuts also does not facilitate establishing a stronger mechanical bond with the concrete. There is a need to design a fastener that can meet the requirements of fastening equipment or devices to a concrete structure without embedding sleeves in the concrete slab.

Therefore, how to solve the above-mentioned drawbacks of the prior art is a direction of efforts of those skilled in the art.

Disclosure of Invention

The utility model aims to provide a rear anchoring chemical internal thread type inverted cone-shaped sleeve which can completely solve the defects in the prior art.

The aim of the utility model is achieved by the following technical scheme:

the utility model provides a back anchor chemistry internal thread formula back taper sleeve, includes the key body, and the internal thread blind hole has been seted up on the top of this key body, and the notch is evenly seted up along circumference to the bottom, is equipped with the back taper on the key body in succession.

Further, 6 reverse cones are continuously arranged, and notches are uniformly formed in the bottom end of the last reverse cone along the circumferential direction.

Further, the lengths of the plurality of reverse cones sequentially increase.

Further, the inverted cone comprises an upper round table and a lower round table, the inverted lower round table is arranged at the bottom end of the upper round table, and the height of the upper round table is larger than that of the lower round table.

Further, the outer diameter of the top end of the plug body is not smaller than 16mm.

Further, the diameter of the internal thread blind hole is 12mm.

Compared with the prior art, the utility model has the beneficial effects that: simple structure, reasonable in design need not the pre-buried sleeve of concrete slab and can realize equipment or device and the quick firm connection of concrete.

1) The adhesive is uniformly distributed and is strongly bonded with the concrete;

2) The tensile strength and the shearing strength are improved, and the bonding interface with concrete is improved;

3) The appearance is improved, and the appearance is smoother and more attractive;

4) Convenient installation, reliable quality, economy and practicality

Compared with the traditional embedded sleeve, the utility model has the beneficial effects that:

1. higher tensile and shear strength. The rear anchoring chemical internal thread type inverted cone sleeve can achieve strong chemical bonding with concrete, and the contact area and stress transmission with the concrete are further increased through the special inverted cone structure, so that higher pulling-out resistance and shearing resistance are obtained.

2. The installation is more convenient. The rear anchoring chemical internal thread type inverted cone sleeve can be directly installed and applied through a rear anchor bolt without pre-embedding the sleeve in advance, so that the construction process is simplified.

3. The appearance is more beautiful. The rear anchoring chemical internal thread type inverted cone sleeve can be directly masked through the inverted cone sleeve, the outer surface is smoother, and the appearance is improved. The traditional embedded sleeve has the effect that the bolt part protrudes out of the concrete surface to influence the appearance.

4. The structure is less affected. The rear anchoring chemical internal thread type inverted cone sleeve can be installed only by drilling, so that the influence on a concrete structure is small; the pre-buried sleeve is required to reserve a cavity in advance before concrete pouring, so that a certain influence can be generated on the concrete structure.

5. The quality is more reliable. The back-anchoring chemical internal thread type back-tapered sleeve can play a role in modifying and reinforcing the anchoring hole, so that the combination quality with concrete is improved; the traditional embedded sleeve is directly exposed in concrete, and the quality of a joint surface is difficult to ensure.

In conclusion, the rear anchoring chemical internal thread type inverted cone sleeve has certain advantages in the aspects of tensile property, construction convenience, appearance, quality reliability and the like.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As shown in fig. 1 to 4, a rear anchoring chemical internal thread type inverted cone sleeve comprises a bolt body 1, wherein an internal thread blind hole 2 is formed at the top end of the bolt body 1, notches 3 are uniformly formed at the bottom end along the circumferential direction, and inverted cones 4 are continuously arranged on the bolt body 1. The top of the bolt body 1 is provided with a head 5, and the side wall of the head 5 is uniformly provided with anti-slip grooves along the circumferential direction. This structural design of the tip 5 facilitates hand-held screwing in use.

Specifically, 6 reverse cones 4 are continuously arranged, and notches 3 are uniformly formed in the bottom end of the last reverse cone 4 along the circumferential direction. And the lengths L of the plurality of reverse cones 4 are sequentially increased. The special back taper of the back anchoring chemical internal thread type back taper sleeve is that the back taper sleeve is provided with a plurality of back tapers 4 with sequentially increased lengths.

The inverted cone 4 comprises an upper circular truncated cone 401 and a lower circular truncated cone 402, the inverted lower circular truncated cone 402 is arranged at the bottom end of the upper circular truncated cone 401, and the height of the upper circular truncated cone 401 is larger than that of the lower circular truncated cone 402.
