Description
Technical Field
The utility model relates to an one-way stay bolt suitable for prefabricated wall body, concretely relates to split type one-way stay bolt of assembled composite wall body.
Background
At present, the existing building wall is a split bolt which penetrates through the outer sides of the two side templates fixed on the wall to play a role in reinforcing the existing wall of the cavity, when a 50mm concrete protective layer is arranged on the outer side, an insulating layer is clamped in the middle, the insulating layer is not damaged, a heat bridge is not generated, and the split bolt plays a role in reinforcing the wall. At present, the traditional split bolt is difficult to realize.
Disclosure of Invention
The utility model aims at overcoming prior art's split bolt, can not pass sandwich thermal insulation wall, otherwise can appear "heat bridge" not enough, provide an equip split type one-way stay bolt of formula composite wall.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a split type one-way pull bolt for an assembled composite wall body is composed of a square base, a screw female column, a screw rod sleeve, a three-shaped fastener and a butterfly screw; a screw nut column is vertically arranged on the central surface of the inner side of the square base, the screw rod is arranged in the screw rod sleeve, screw threads are arranged at two ends of the screw rod, a screw hole for mounting the screw thread at one end of the screw rod is arranged at the horizontal central position of the screw nut column, and the other end of the screw rod passes through the central screw hole of the three-shaped fastener and is fastened and connected into a whole through the butterfly screw; the upper end of the nut screw column is provided with a separation blade, and the periphery of the separation blade is provided with a sealing ring groove.
Further, the EPS heated board outside is filled with the concrete, and concrete thickness is 50mm, and the lead screw that passes in the lead screw sleeve pipe and it passes interior template, wire net and EPS heated board in the lump and square base is connected and is formed one-way stay bolt component.
The beneficial effects of the utility model are that, the utility model discloses simple structure, processing is convenient, and low in manufacturing cost is fit for batch production, satisfies the user demand that the building volume is big, utilizes simultaneously the utility model discloses fix in the EPS heat preservation plate outside 50mm concrete, the screw pole passes interior sheathing and EPS heat preservation plate and is connected with the base and forms one-way bolt component that draws, ensures that wall thickness size accuracy pouring concrete does not rise the mould, and construction installation progress is fast, and the reuse is retrieved to the lead screw behind the form removal, practices thrift the consumptive material.

the heat-insulation composite plate comprises a square base 1, a screw female column 2, a screw sleeve 3, a screw rod 4, a three-shaped fastener 5, a butterfly screw 6, heat-insulation layer concrete 7, a steel wire mesh 8, an EPS heat-insulation plate 9, structural concrete 10, an inner formwork 11 and a one-way pull bolt 12.
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.
Example 1
Referring to the attached drawings 1 and 2, the bolt is composed of a square base 1, a nut screw column 2, a screw rod 4, a screw rod sleeve 3, a three-shaped fastener 5 and a butterfly screw 6; a nut column 2 is vertically arranged on the central surface of the inner side of the square base 1, the screw rod 4 is arranged in the screw rod sleeve 3, threads 401/402 are arranged at two ends of the screw rod 4, an EPS heat insulation board 9 is arranged on the surface of the screw rod, a screw hole for installing a screw thread 401 at one end of the screw rod 4 is arranged at the horizontal central position of the nut column 2, and a screw thread 402 at the other end of the screw rod 4 penetrates through a central screw hole of the three-shaped fastener 5 and is fastened and connected into a whole through a butterfly screw 6; the upper end of the screw nut column 2 is provided with a separation blade, and the periphery of the separation blade is provided with a sealing ring groove.
Referring to fig. 3, the second embodiment of the present invention is combined with the first embodiment,
during the installation, EPS heated board 9 wears admittedly in 2 inner faces of nut screw post through nut screw post 2, installs wire net 8 in the separation blade recess of 2 front ends of nut screw post, and 4 left ends screw thread 401 of lead screw fasten with the screw hole of nut screw post 2, and 4 right-hand members screw thread 402 of lead screw pass the central screw hole of interior template 11 and three-shaped fastener 5 to through the fastening of butterfly screw 6, the fastening can be by the layering fastening form single file stay bolt 12.
And (3) pouring heat insulation layer concrete 7 in a gap between the heat insulation layer and the left side of the EPS heat insulation plate 9, and pouring structural concrete 10 in a gap between the right side plate of the EPS heat insulation plate 9 and the inner template 11.
It should be noted that, in the concrete with the thickness of 50mm filled outside the EPS heat insulation board 9, the screw rod 4 penetrates through the inner formwork 11, the steel wire mesh 8 and the EPS heat insulation board 9 to be connected with the square base 1 to form the one-way stay bolt member 12.
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.
