Background

In the construction process of the concrete sandwich heat-insulating wall body, a structural template, a heat-insulating layer, a steel wire mesh and the like need to be assembled by using corresponding connecting pieces. The patent document named as 'internal and external combined supporting component of sandwich heat-insulating wall' discloses a product similar to the invention, but the product does not well solve the problems of firm combination of assembly accessories and concrete, convenient assembly, wide applicability and the like.

Disclosure of Invention

The invention aims to provide a supporting and stressing assembly of a sandwich thermal insulation wall, which is firmly combined with wall concrete and is convenient and fast to install.

The purpose of the invention is realized as follows: including supporting stress pole, connecting piece main part, stop sleeve and conversion nut, support stress pole, connecting piece main part, stop sleeve and conversion nut and be the components of a whole that can function independently structure, the cross section of connecting piece main part be the I shape, there is the through-hole in the centre of connecting piece main part, the front end of supporting the stress pole has the screw thread, support the stress pole and pass the through-hole in the middle of the connecting piece main part, stop sleeve overlaps on supporting the stress pole, the conversion nut is installed and is being supported the stress pole front end.

The present invention may further comprise:

1. one side of the I-shaped cross section of the connecting piece main body is a bevel edge, and the other side of the I-shaped cross section of the connecting piece main body is a step edge.

2. One end of the stair edge of the I-shaped cross section of the connecting piece main body is provided with through holes which are distributed annularly.

3. The front end of the supporting stress rod forms a gasket.

The support stress rod, the connecting piece main body, the limiting sleeve and the conversion nut are of split structures, protective layers and wall structure layers with different thicknesses can be obtained by selecting the sizes of the connecting piece main body, the limiting sleeve and the like, and the support stress rod has wide applicability and is convenient to process, transport and construct. When the connecting piece is used, the supporting stress rod penetrates through the through hole in the middle of the connecting piece main body and then penetrates through the heat insulation layer, the connecting piece main body is fixed on the outer side of the heat insulation layer, and the thickness of the protective layer is determined by the connecting piece main body; secondly, sleeving a limiting sleeve on the supporting stress rod, wherein the limiting sleeve is positioned on the inner side of the heat insulation layer to limit the thickness of the wall structure layer; and finally, installing a conversion nut at the front end of the supporting stress rod, and fixing the conversion nut on the inner template by matching with the counter bolts and the like.

The cross section of the connecting piece main body is I-shaped, after the protective layer is poured with concrete, the contact area between the connecting piece main body and the concrete is large, and the connecting piece main body is embedded into the concrete, so that the drawing strength is increased, and the protective layer is prevented from falling off. According to the invention, the connector main body is optimally designed, so that an I-shaped annular groove with one inclined surface at one side and a stepped surface at the other side is formed in the middle of the connector main body, the contact area between the connector main body and concrete is larger, friction is increased, and the protective layer is prevented from falling off; the connecting piece main part is distributed with through holes, and the hole design integrates the connecting piece main part, the supporting stress rod, the wall structure and the like when the protective layer is poured with concrete, so that the protective layer is prevented from falling off. The main body structure is complete and firm. .

The supporting stress rod can be integrally molded with the connecting piece main body in an injection molding mode, the structure is simple, the manufacturing is easy, the supporting stress rod hole is preset in the corresponding heat insulation template, the operation difficulty of a construction site is reduced, and meanwhile, the site construction procedures are reduced.

Detailed Description

The invention is described in more detail below by way of example.

With reference to fig. 1 to 8, the first embodiment of the present invention comprises a connector body 1, a support stress rod 3, a limit sleeve 2 and a conversion nut 6. The supporting stress rod is a steel bar rod, the front end of the supporting stress rod is provided with a gasket, and the rear end of the supporting stress rod is provided with a thread 4. The front end of the limiting sleeve 2 is provided with a disc 5. The conversion nut 6 comprises a first section of nut 7 and a second section of nut 8, and plastic sleeves connected with the nuts into a whole are arranged outside the two sections of nuts. The cross section of the connecting piece main body is an I-shaped groove 1-3, and a through hole 1-1 is arranged in the middle of the connecting piece main body. The connecting piece main part and the limiting sleeve are injection-molded parts. With reference to fig. 9, when the sandwich thermal insulation wall is used, the supporting stress rod firstly penetrates through the through hole in the middle of the connecting piece main body and then penetrates through the thermal insulation layer, the connecting piece main body is fixed on the outer side of the thermal insulation layer, and the thickness of the protective layer is determined by the connecting piece main body; secondly, sleeving a limiting sleeve on the supporting stress rod, wherein the limiting sleeve is positioned on the inner side of the heat insulation layer to limit the thickness of the wall structure layer; and finally, installing a conversion nut at the front end of the supporting stress rod, and fixing the conversion nut on the inner template by matching with the counter bolts and the like.

The second embodiment of the invention is based on the first embodiment, and one side of the I-shaped cross section of the connecting piece main body is designed to be a bevel edge 1-2, and the other side is designed to be a step edge 1-4.

In a third embodiment of the invention, on the basis of the first or second embodiment, through holes 1-5 distributed in a ring shape are formed at one end of the step edge of the I-shaped cross section of the connecting piece main body.
