The invention is realized by the following steps:
the invention relates to a turnover type auxiliary wall-attached support which comprises a support, wherein the support is composed of a horizontal plate and a vertical plate, the vertical plate is welded on the horizontal plate, a round hole is formed in the horizontal plate, a high-strength bolt is in threaded connection with a nut which is welded with a gasket in advance through the round hole, one end of the high-strength bolt connected with the nut is embedded in a concrete member, and the support is fastened on the concrete member through the high-strength bolt connected with the nut.
Further, the high-strength bolt is an M24 hexagon-head high-strength bolt, the length of the M24 hexagon-head high-strength bolt is larger than or equal to 180mm, and the strength grade is more than 8.8.
Furthermore, the vertical plate is provided with a mounting hole.
The application method of the turnover auxiliary wall-attached support comprises the steps that when a concrete member is poured, a high-strength bolt penetrates through a round hole of a horizontal plate on the support and is in threaded connection with a nut welded with a gasket in advance, then the high-strength bolt connected with one end of the nut and the concrete member are poured simultaneously, one section of the high-strength bolt, the gasket and the nut are embedded in the concrete member simultaneously, the horizontal plate of the support is in contact fit with the surface of the concrete member, and after the concrete poured into the concrete member is solidified, the support and the concrete member can be tightly connected together; when the support needs to be dismantled, the high-strength bolt can be separated from the nut only by rotating the hexagon head on the high-strength bolt, so that the support and the high-strength bolt are separated from the concrete member and are dismantled, and the dismantled support and the high-strength bolt are used for circulation.
Due to the adoption of the technical scheme, compared with the prior art, the invention can provide enough anchoring force, ensure the bearing capacity requirement of wall-attached equipment, can also repeatedly utilize the support and the high-strength bolt, greatly reduces the cost, and simultaneously can avoid secondary formwork support when concrete repair is carried out at the later stage, thereby simplifying the subsequent construction process; in addition, the invention not only overcomes the defect of high construction cost of the traditional embedded part, but also greatly simplifies the later-period restoration construction of the concrete structure because the wall penetration and the punching are not needed.

Detailed Description
The invention is further illustrated by the following figures and examples.
Please refer to fig. 1-3: the invention discloses a turnover auxiliary wall-attached support which comprises a support 1, wherein the support 1 is composed of a horizontal plate 2 and a vertical plate 3, the vertical plate 3 is welded on the horizontal plate 2, a round hole 4 is formed in the horizontal plate 2, a high-strength bolt 5 is in threaded connection with a nut 6 which is welded with a gasket 7 in advance through the round hole 4, the high-strength bolt 5 is an M24 hexagon-head high-strength bolt, the length of the M24 hexagon-head high-strength bolt is larger than or equal to 180mm, the strength grade is more than 8.8 grade, one end of the high-strength bolt 5 connected with the nut 6 is embedded in a concrete member 9, the support 1 is fastened on the concrete member 9 through the high-strength bolt 5 connected with the nut 6, and a mounting hole 8 is formed in the vertical plate 3.
The invention also provides a using method for the turnover auxiliary wall-attached support, which is characterized in that when a concrete member 9 is poured, a high-strength bolt 5 penetrates through a round hole 4 of an upper horizontal plate 2 of the support 1 in advance to be in threaded connection with a nut 6 welded with a gasket 7, then the high-strength bolt 5 connected with one end of the nut 6 and the concrete member 9 are poured simultaneously, so that one section of the high-strength bolt 5, the gasket 7 and the nut 6 are embedded in the concrete member 9 simultaneously, the horizontal plate 2 of the support 1 is in contact fit with the surface of the concrete member 9, and after the concrete poured into the concrete member 9 is solidified, the support 1 and the concrete member 9 are tightly connected together; when the support 1 needs to be dismounted, the high-strength bolt 5 can be separated from the nut 6 only by rotating the hexagonal head on the high-strength bolt 5, so that the support 1 and the high-strength bolt 5 are separated from the concrete member 9 for dismounting, and the dismounted support 1 and the dismounted high-strength bolt 5 are used for circulation.
Example 1:
1. welding the nut 6 and the gasket 7 in advance;
2. after two M24 hexagonal-head high-strength bolts penetrate through the round hole 4, screwing the nut 6 and the gasket 7 which are firmly welded in advance into the position of 1-2cm away from the tail end of the high-strength bolt 5;
3. the screw thread and the screw rod of the bolt 5 (i.e. the part embedded in the concrete) are coated with butter;
4. when concrete pouring is finished, the support 1 is taken up by two hands, the bolt 5 is pressed by the thumb, one section of the high-strength bolt 5, the gasket 7 and the nut 6 are gradually inserted into concrete on a structural floor (above a beam structure) in a repeated inserting and tamping mode until the horizontal plate 2 of the support 1 is contacted with the concrete surface, then the support is slightly fixed by hand, and the concrete around is inserted and tamped by using a vibrating rod or a steel bar until the concrete at the inserted part is vibrated and tamped tightly;
5. and after the concrete is solidified and hardened for about 3 days, the mounting holes 8 in the vertical plates 3 of the support 1 can be used, and the universal joint is matched to be connected with the wall-attached rod piece, so that the mounting operation of the equipment is completed.
6. When the wall-attached support needs to be detached, the bolt 5 can be unscrewed by using a hexagonal wrench or an electric wrench, and because lubricating oil is coated on the bolt 5 in advance, the torque in the unscrewing process can be controlled below 300 N.m, so that the wall-attached support has good operability.
7. When concrete structure is repaired, because the anchoring end of the support does not penetrate through the beam slab structure, secondary formwork support is not needed, and only high-strength grouting material or high-strength fine aggregate concrete is poured into the holes after hole cleaning treatment.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included therein.
