Description

Novel heat preservation drawknot spare

Technical Field

The utility model relates to a sandwich insulation wallboard drawknot installation auxiliary, concretely relates to novel heat preservation drawknot spare.

Background

At present, in a building project, a heat insulation wall body used conventionally is divided into an inner heat insulation wall body and an outer heat insulation wall body. The problems that the inner heat-insulating wall body has a heat bridge phenomenon and the inner heat-insulating layer is easy to crack and the like are solved; the outer thermal insulation wall has the problems of fire resistance, durability, negative wind pressure resistance and the like. Along with the popularization of the fabricated building, the sandwich heat-insulating wall board is popularized and applied in a large area as a novel heat-insulating wall body.

Sandwich sandwich insulation wallboard is that the collection bears the weight of and keeps warm the integration novel prefabricated thermal insulation wall, and this wall comprises leaflet concrete wallboard + heat preservation + leaflet concrete wallboard and heat preservation drawknot spare, and heat preservation drawknot spare is the key component of connecting sandwich heat preservation inside and outside leaflet wallboard and middle heat preservation, and its main function is the shearing action between the layer of resisting between two concrete wallboard. Depending on the material, the tie members are mainly classified into stainless steel tie members and glass fiber tie members. The stainless steel tie piece is limited in popularization and use due to high manufacturing cost, inconvenient installation and the like. The glass fiber pulling-up piece is easy to pull out in anchoring performance, and some glass fiber pulling-up pieces in the current market are inconvenient to mount and the like.

Disclosure of Invention

The utility model aims at overcoming the not enough of above-mentioned prior art, provide a novel heat preservation drawknot spare, can guarantee the reliability of good energy-conserving effect and connection, can have bigger economic nature again.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a novel heat-insulating drawknot piece comprises a cylindrical or square-column-shaped drawknot piece main body and a lacing wire hook body, wherein the drawknot piece main body is made of glass fiber materials, and the lacing wire hook body is made of stainless steel materials; a through hole is formed in the middle of the tie piece along the length direction of the tie piece main body, and after the tie bar hook body penetrates through the through hole, 135-degree hooks are formed at the two exposed ends of the tie bar hook body inwards and are arranged symmetrically in the vertical direction; and injecting sealant into a gap between the tie piece main body and the lacing hook body or arranging limiting grooves at two ends of the tie piece main body, connecting the limiting grooves by using limiting caps sleeved on the lacing hook body in a threaded manner, and finally fixing the tie piece main body and the lacing hook body.

Further, the length of the straight section of the hook is five times the diameter d of the hook, or the length of the straight section of the hook is 5 d.

Further, the length of the drawknot body is 38mm + the thickness of the insulating layer +38 mm.

Furthermore, the bending radius of the hook is four times the hook diameter d, or the bending radius of the hook is 4 d.

Further, the inner diameter of the through hole is the length of the hook with the diameter d +0.1 mm.

The beneficial effects of the utility model are that, the utility model discloses a nonrust rebar hook both ends are connected with the reinforcing bar net piece of inner leaf concrete wallboard, outer leaf concrete wallboard structure layer respectively, connect reliably, and anchoring performance is superior. And simultaneously, the glass fiber material with low price is adopted for compounding the shear resistance. The stainless steel lacing wire hook with the diameter of 4mm is structurally connected, so that the cost is greatly reduced by about 40 percent compared with a stainless steel connecting piece; meanwhile, the usage amount of the heat-preservation drawknot piece is 3-4 per square meter, which is more convenient than that of stainless steel drawknot pieces and glass fiber drawknot pieces. The production efficiency of sandwich heat-insulating wall board is improved.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a perspective view of the present invention;

wherein 1, the drawknot main body and 2, the lacing wire hook body.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1 and 2, a novel heat-insulating drawknot component comprises a drawknot component main body 1 and a lacing wire hook body 2; the lacing element main body 1 is in a cylindrical shape or a square cylindrical shape prepared from glass fiber materials, and the lacing wire hook body 1 is prepared from stainless steel materials; along the length direction of the drawknot main body 1, a through hole is arranged in the middle of the drawknot main body, the lacing wire hook body 2 is inserted into the through hole, and two end parts of the lacing wire hook body 2 exposed outside two ends of the drawknot main body 1 are bent inwards by 135 degrees to form a hook. In order to prevent the stainless steel lacing wire hook body 2 and the glass fiber lacing part body 1 from sliding, sealant is injected into a through hole gap at the joint of the stainless steel lacing wire hook body and the glass fiber lacing part body for fixing; or two ends of the drawknot body 1 are provided with limit grooves or external threads, and the nut corresponding to the limit grooves is sleeved on the lacing wire hook body made of stainless steel material to be in threaded connection and fixed.

In actual production and use, the length of the straight section main body of the lacing wire hook body hook can be set to be five times of the diameter of the hook; simultaneously, for the firm degree of the two of the better linking drawknot spare main part, lacing wire coupler body of being convenient for, set up the internal diameter of through-hole for the crotch diameter plus 0.1 mm's length. The bent inner diameter of the hook of the lacing wire hook body is four times of the diameter and the length of the hook.

For the better drawknot effect of adaptation heated board, set up the length of drawknot spare main part into thirty eight millimeters + insulating layer thickness + thirty eight millimeters's length.

The utility model discloses a so set up 1 main part of drawknot spare main part into the preparation of glass fiber material, its purpose is exactly that it is strong to combine glass fiber to cut shear, and the cost of manufacture is cheap than stainless steel material cost.

The utility model discloses still adopt the stainless steel drag hook with lacing wire coupler body 2 to with its both sides crotch incurvation 135 formation crotch, its purpose is to improve its bending resistance, resistance to plucking intensity.

When in use, the using amount of each square meter of the area of the wallboard is not less than three to four; the door and window opening and the peripheral position of the wall can be locally reinforced.

Although the specific embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, and various modifications or variations that can be made by those skilled in the art without creative efforts are still within the scope of the present invention.
