Abstract

The utility model discloses an anchor backing plate, which comprises a backing plate provided with a throughhole in the middle; the outer layer of the backing plate is provided with a shell enclosed by a metal component; concrete is filled inside the shell of the backing plate; a skeleton is arranged in the concrete. Compared with the prior art, the anchor backing plate resolves the problem that the large consumption of steel material and the high transportation cost cause a high project cost when the prior anchor backing plate is produced.

Description

Anchor plate

Technical field

The utility model is the building unit technical field, the anchor plate that especially a kind of prestress anchoraging is used.

Background technology

The main effect of anchor plate is transmitted load and dispersive stress, and it is a part very important in the prestress anchorage system.At present, the anchor plate that uses mainly contains two kinds both at home and abroad, and a kind of is that an end is square backing plate, and the other end progressively is shrunk to cone shape, and the anchor plate of this structure is to adopt the cast iron monoblock cast to form.Another kind is the backing plate that is plate, adopts the steel plate manufacturing.The anchor plate of above-mentioned two kinds of structures adopts cast iron or steel plate manufacturing during fabrication fully, and it is many therefore to expend steel, and the freight height causes engineering cost also than higher.

Summary of the invention

Problem to be solved in the utility model is: provide a kind of and can save great deal of steel on the basis that guarantees workmanship, thereby reduce the anchor plate that freight reduces engineering cost greatly.

In order to address the above problem, the scheme that the utility model adopts is: include the backing plate that the middle part has through hole, the skin of described backing plate is the housing that is surrounded by hardware, and the inside of described backing plate housing is filled with concrete, is placed with skeleton in concrete.

In such scheme, described housing can be to adopt two blocks of hardwares that have groove to fasten, and connects and composes with screw; Described skeleton can be the plate that is bellows-shaped, and its peak line radially radially distributes with the center line of described backing plate through hole; Described skeleton can have two at least, and they are placed in the concrete inner stacks, increase the intensity of backing plate with this; Outside the through hole of described backing plate conical pipe can be housed, the big end and the described backing plate of this conical pipe are fixed, and the small end of this conical pipe is equipped with ring.

Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:

1, saves great deal of steel, reduce engineering cost.Because the outer of backing plate backing plate once was the housing that is surrounded by hardware, and was filled with concrete in the inside of backing plate housing, therefore reduced the consumption of steel, from reducing engineering cost.

2, the stress of concentrating is progressively disperseed to expand on the big stress surface, stress is reduced, structural safety is reliable.Owing in the concrete that the backing plate enclosure interior is filled, be placed with skeleton, by layer of concrete and skeleton the stress of concentrating is progressively disperseed expansion, make stress reduce, structural safety is reliable.

The specific embodiment

Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:

In Fig. 1, embodiment 1 shown in Figure 2, the skin that the middle part has the backing plate of through hole 6 is to adopt two blocks of hardware 1 and hardwares 2 that have recessed groove to fasten mutually, and the housing that connects and composes with screw 4.In housing, promptly fill full concrete in the cavity that the groove of being opened by hardware 1 and hardware 2 forms behind fastening, be placed with two groups of skeletons in the concrete inner stacks, this skeleton 5 is plates of bellows-shaped, its peak line is radially radially distributing with the center line of backing plate through hole, every group is superimposed with each other by two skeleton 5 Wave crest and wave troughs and constitutes, and wherein the crest of the crest of one group of skeleton and adjacent set skeleton is crisscross arranged

In Fig. 3, embodiment 2 shown in Figure 4, the skin that the middle part has the backing plate of through hole 106 is to adopt two blocks of hardware 101 and hardwares 102 that have recessed groove to fasten mutually, and the housing that connects and composes with screw 104.Fill full concrete in the cavity that the groove of promptly being opened by hardware 101 and hardware 102 forms behind fastening in housing, be placed with two groups of skeletons in the concrete inner stacks, this skeleton 105 is plates of bellows-shaped, its peak line is radially radially distributing with the center line of backing plate through hole, every group is superimposed with each other by two skeleton 105 Wave crest and wave troughs and constitutes, and wherein the crest of the crest of one group of skeleton and adjacent set skeleton is crisscross arranged.Through hole 106 at backing plate is externally connected with conical pipe 107, and the big end of this conical pipe 107 is provided with the limit of annular so that mounting screw 108 is fixing with itself and hardware 102, and the small end of conical pipe 107 is provided with screens, dress ring 109 in this screens.

The utility model during fabrication, the hardware and the skeleton that surround housing all can adopt the steel plate punching press to make.Tapered pipe adopts plastics to make, and ring is then formed by the steel pipe machine.In use, can select the anchor plate of embodiment 1 or 2 two kinds of different structures of embodiment for use according to requirement of engineering.When selecting structure shown in the embodiment 2 for use, requiring tapered pipe and confinement ring all to be embedded in the concrete can use.
