Waterproof type composite heat preservation non-dismantling formwork anchoring part

Abstract

The utility model discloses a waterproof type composite heat preservation non-dismantling formwork anchoring part which comprises an anchoring part body, the anchoring part body comprises a twisted steel, a nylon sleeve is fixedly connected to the outside of the twisted steel in a sleeved mode, and a plurality of water stop rings are fixedly connected to the outer walls of the two sides of the nylon sleeve in a sleeved mode. The outer wall, located in the middle of the water stop ring, of the nylon sleeve is fixedly connected with symmetrically-arranged non-return teeth, and one side of the twisted steel is fixedly connected with a disc. The heat preservation layer has the advantages that the water stop ring is arranged on the nylon sleeve, and water in concrete is prevented from being poured into the heat preservation layer in the concrete pouring process; external rainwater is prevented from flowing into the heat preservation layer through the anchoring part by arranging a water stop ring at the disc end of the end cap and connecting a flexible rubber sealing ring to the disc in a sleeving mode; the anchoring stability of the anchoring part and the wall body structure is improved by embedding the water stop ring into the concrete; the four rows of non-return teeth are arranged, so that the adhesive force of the anchoring part and the composite heat preservation formwork is increased.

Description

Technical Field

[0001] The utility model relates to the field of composite thermal insulation non-disassembly formwork construction, in particular to a waterproof composite thermal insulation non-disassembly formwork anchoring piece. Background Art

[0002] The composite thermal insulation non-removal formwork does not need to be removed after the concrete is poured and can be directly used as the thermal insulation layer of the wall. However, the composite thermal insulation formwork has a large deadweight and is affected by the environment. Its bonding strength with the cast-in-place concrete alone is far from meeting the requirements for safe and durable use. Therefore, anchors are required to strengthen the adhesion between the composite thermal insulation non-removal formwork and the wall structure.

[0003] At present, the anchors used in composite insulation non-removal formwork only consider the anchoring function, but do not consider the problem of waterproofing at the anchor position. When pouring concrete, the water in the concrete will flow into the insulation layer through the anchor holes, causing the performance of the insulation layer material to be destroyed. After the concrete construction is completed, rainwater will also flow into the insulation layer through the anchor holes, causing damage to the insulation material. Utility Model Content

[0004] The utility model aims to provide a waterproof composite thermal insulation non-disassembly template anchor to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof composite thermal insulation non-disassembly formwork anchor, including an anchor body, the anchor body including a threaded steel bar, a nylon sleeve is fixedly sleeved on the outside of the threaded steel bar, and a plurality of waterstop rings are fixedly sleeved on the outer walls of both sides of the nylon sleeve, the outer wall of the nylon sleeve located in the middle of the waterstop ring is fixedly connected with symmetrically arranged check teeth, and a disc is fixedly connected to one side of the threaded steel bar.

[0006] Preferably, a rubber sealing ring is fixedly sleeved on the outside of the disc.

[0007] Preferably, the water stop rings are arranged in an array outside the nylon sleeve.

[0008] Preferably, the threaded steel bar is longer than the nylon sleeve.

[0009] Compared with the prior art, the utility model has the following beneficial effects: by arranging a waterstop ring on the nylon sleeve, water in the concrete is prevented from flowing into the insulation layer during the concrete pouring process; by the waterstop ring at the end of the end cap disc and the flexible rubber sealing ring sleeved on the disc, external rainwater is prevented from flowing into the insulation layer through the anchor; by embedding the waterstop ring in the concrete, the anchoring stability of the anchor and the wall structure is increased; by arranging four rows of check teeth, the adhesion of the anchor and the composite insulation formwork is increased.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-3 The utility model provides a technical solution: a waterproof composite thermal insulation non-disassembly formwork anchor, including an anchor body 1, the anchor body 1 includes a threaded steel bar 2, a nylon sleeve 3 is fixedly sleeved on the outside of the threaded steel bar 2, and a plurality of water stop rings 4 are fixedly sleeved on the outer walls of both sides of the nylon sleeve 3, the outer wall of the nylon sleeve 3 located in the middle of the water stop ring 4 is fixedly connected with a symmetrically arranged check tooth 5, and a disc 7 is fixedly connected to one side of the threaded steel bar 2.

[0016] A rubber sealing ring 6 is fixedly sleeved on the outside of the disc 7, which is beneficial to prevent rainwater from flowing into the insulation layer through the rubber sealing ring 6.

[0017] The water stop rings 4 are arranged in an array outside the nylon sleeve 3, which is beneficial to prevent water on both sides of the composite insulation non-removal formwork from flowing into the insulation layer through the water stop rings 3, and at the same time enhance the tensile strength of the anchor in the wall structure.

[0018] The length of the threaded steel bar 2 is longer than the nylon sleeve 3, which is conducive to driving the anchor piece to be inserted into the concrete as a whole for limited installation through the longer threaded steel bar 1.

[0019] Specifically, when the utility model is used, when the waterproof composite thermal insulation non-disassembly formwork anchor is used, the anchor body 1 is driven by the disc 7 to be inserted into the composite thermal insulation non-disassembly formwork as a whole, and the nylon sleeve 3, the water stop ring 4 and the check tooth 5 are driven by the threaded steel bar 2 to be inserted into the composite thermal insulation non-disassembly formwork, and the rubber sealing ring 6 outside the disc 7 is used to initially prevent water from flowing into the insulation layer, and then the water stop ring 4 outside the nylon sleeve 3 is used to block the flow, which not only prevents water on both sides of the composite thermal insulation non-disassembly formwork from flowing into the insulation layer, but also enhances the pull-out resistance of the anchor body 1 and the wall structure, and during installation, the symmetrical check teeth 5 on the nylon sleeve 3 are inserted into the formwork to prevent the anchor body 1 from retreating, thereby improving the installation adhesion of the anchor body 1 and the insulation formwork.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
