Abstract
The invention discloses a prestress nut pad, which comprises a pad plate, wherein the pad plate is a vertical straight plate; elastic positioning hitching legs are arranged at the upper part and the lower part of the pad plate respectively; the elastic positioning hitching legs at the upper part and the lower part of the pad plate are all positioned on the same side of the pad plate; the highest point of the elastic positioning hitching leg at the upper part of the pad plate is higher than the top part of the pad plate; the lowest point of the elastic positioning hitching leg at the lower part of the pad plate is lower than the bottom of the pad plate; and an elastic deformation can be generated at the connecting part of each elastic positioning hitching leg and the pad plate. When the pad plate enters a cavity of a frame material, the elastic positioning hitching legs can support the inner wall of the cavity always, so that the prestress is generated for keeping the position of the pad plate, the fixed connection of the pad plate is not required; when the positions of connecting holes are machined, the generated axial force is balanced through the clearance fit of the elastic positioning hitching legs and the inner wall of the cavity; and the thicknesses of the frame material and the pad plate are overlapped, so that the connection strength of connecting screws on the frame materials is improved.
Description
Technical field
The present invention relates to a kind of nut pad, particularly a kind of good positioning effect, prestressing nut pad easy for installation, belong to five metals component technology field.
Background technique
The forms framework of curtain wall openable windows adopts aluminium alloy extrusions usually, but because the curtain wall openable windows to the restriction of material wall thickness, causes the join strength of attachment screw of aluminium alloy extrusions and sliding support, wind brace inadequate, and so that the bulk strength deficiency of curtain wall openable windows; Under the effect of blast vibrating load, the screw loosening of connection part often can appear; When serious, the thread failure of the screw joint of aluminium section bar can appear; If during use, damaging appears in sliding support, wind brace, then can't change, and has caused obstruction to maintenance; A kind of liner nut shim of general employing improves the local join strength of aluminium alloy extrusions now, but the processing of this liner nut shim, the assembling all very complicated, if need to change different sliding support, wind brace, or use is not sliding support, the wind brace of same batch of production, the inconsistent situation in position, hole of attachment screw then can occur, bring inconvenience to installation.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of good positioning effect, prestressing nut pad easy for installation.
Technical solution of the present invention is achieved in that a kind of prestressing nut pad, comprises backing plate, and described backing plate is vertical straight plate, and the upper and lower of backing plate is equipped with elasticity location hanging feet; The elasticity location hanging feet of the upper and lower of described backing plate all is positioned at the same side of backing plate; The peak of the elasticity location hanging feet on described backing plate top exceeds the top of backing plate; The minimum point of the elasticity location hanging feet of described backing plate bottom is lower than the bottom of backing plate; The joint of described elasticity location hanging feet and backing plate can produce resiliently deformable.
Preferably, the joint of described elasticity location hanging feet and backing plate is provided with the prestressing force groove near a side at backing plate center.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Prestressing nut pad of the present invention comprises backing plate, and backing plate is provided with elasticity location hanging feet, when backing plate entered in the die cavity of frame material, elasticity location hanging feet propped up the die cavity inwall all the time, and produces prestressing force, keep the position of backing plate, no longer need in addition backing plate to be fixed connection; Add man-hour when carrying out the attachment hole position, the axial force of generation is come balance by the interference fit of elasticity location hanging feet and die cavity inwall; And because the thickness of frame material and backing plate is superimposed, improved the join strength of the attachment screw on the frame material.

Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the plan view of prestressing nut pad of the present invention;
Accompanying drawing 2 is that prestressing nut pad of the present invention is applied in the partial sectional view in the curtain wall openable windows;
Accompanying drawing 3 for prestressing nut pad of the present invention be applied in the curtain wall openable windows A-A to partial sectional view;
Wherein: 1, backing plate; 2, elasticity location hanging feet; 3, prestressing force groove; 4, outer fixing frame; 5, interior fixing frame; 6, sliding support square groove; 7, square groove attachment screw; 8, sliding support; 9, trailing arm attachment screw.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a kind of prestressing nut pad of the present invention, comprises backing plate 1, and described backing plate 1 is vertical straight plate, and the upper and lower of backing plate 1 is equipped with elasticity location hanging feet 2; The elasticity location hanging feet 2 of the upper and lower of described backing plate 1 all is positioned at the same side of backing plate 1; Described elasticity location hanging feet 2 is " V " font; The peak of the elasticity location hanging feet 2 on described backing plate 1 top exceeds the top of backing plate 1; The minimum point of the elasticity location hanging feet 2 of described backing plate 1 bottom is lower than the bottom of backing plate 1; Described elasticity location hanging feet 2 is provided with prestressing force groove 3 with a side at the center of the close backing plate 1 of joint of backing plate 1; Described elasticity location hanging feet 2 can produce resiliently deformable with the joint of backing plate 1.
Be a kind of fixed frame of curtain wall openable windows such as Fig. 2-3, comprise fixed frame assemblies, sliding support 8; Described fixed frame assemblies comprises outer fixing frame 4, interior fixing frame 5; Described outer fixing frame 4 and interior fixing frame 5 are the quadra of hollow, and outer fixing frame 4 is equipped with vertical backing plate 1 with the inside of interior fixing frame 5; The elasticity of described each backing plate 1 location hanging feet 2 all with the corresponding inwall interference fit of the up and down both sides of outer fixing frame 4 or interior fixing frame 5; The outside of described outer fixing frame 4 is provided with sliding support square groove 6; Described sliding support square groove 6 is fixed on outer fixing frame 4 near on the outer wall of interior fixing frame 5 by square groove attachment screw 7, and square groove attachment screw 7 passes the backing plate 1 in the outer fixing frame 4; One side of described sliding support 8 is arranged in the sliding support square groove 7, and the opposite side of sliding support 8 is fixed on the interior fixing frame 5 by trailing arm attachment screw 9; Described trailing arm attachment screw 9 passes the backing plate 1 in the interior fixing frame 5.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
