Description
Technical field
This utility model belongs to construction aid technical field, is specifically related to a kind of backplate plastered for right angle external corner。
Background technology
In housing construction process, body of wall or the external corner of pillar in building are required for smearing sand-lime, the requirement of the sand-lime that external corner uses is higher than metope, existing method is first to be generally the sand-lime of 1:3 by the weight ratio of the sand-lime of metope and cement and coarse sand all to have whitewashed, then is rooted out by the sand-lime that external corner place is stuccoed and the weight ratio of rendering concrete and coarse sand should be the sand-lime of 1:2。This mode is long in time limit, also wastes raw material。
Although the external corner backplate that CN201520491765.X discloses to some extent solves this problem, but the external corner being found that again new problem body of wall or pillar in actual use is often square, and existing external corner backplate is usually and is combined into existing timber, but its angle is difficult to ensure that to be just 90 °, therefore in use, this external corner backplate tends not to fit well with external corner。Fit and bad bring two hidden danger: one is owing to external corner backplate and body of wall have angle, has stress and concentrate on backplate, body of wall and damage backplate or body of wall when fixing；Two is not in place owing to fitting, and makes the requirement being smaller in size than construction quality standard of real protection。
Additionally, existing external corner backplate is usually fixed at a right angle, it is not easy to storage。
Summary of the invention
For prior art above shortcomings, the purpose of this utility model is in that to provide a kind of backplate plastered for right angle external corner posted and be easy to storage with body of wall。
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of backplate plastered for right angle external corner, including two sub-backplates that entirety is rectangular, it is characterized in that, a long limit of one of them sub-backplate is provided with several projections, a long limit of another sub-backplate is provided with several shrinkage pools matched with described projection；Two sub-backplates are plugged in together by described projection and shrinkage pool, so that the angle of two sub-backplates is 90 °。
Further, described shrinkage pool is arranged on one piece of sub-backplate being of a size of 2000 × 65 × 15mm, and described projection is arranged on another block and is of a size of on the sub-backplate of 2000 × 50 × 15mm, to be spliced into the equilateral right angle L-shaped of 2000 × 65 × 15mm。
Further, described sub-backplate is spliced by the molecule backplate of two pieces of area equation and forms。
Further, described projection and the cross section of shrinkage pool are square or circular。
Further, described sub-backplate is provided with installing hole, is used for and wall connecting。
Compared with prior art, this utility model has the advantages that
1, the mode of grafting is adopted to combine between two sub-backplates of the present utility model, it is possible to ensure that the two folded angle is right angle, it is simple to fit with right angle external corner, greatly protect body of wall。
2, grafting, simple in construction are adopted between two sub-backplates of the present utility model, it is simple to storage。
Accompanying drawing explanation
Fig. 1 is the sub-backplate that this utility model is provided with projection；
Fig. 2 is the sub-backplate that this utility model is provided with shrinkage pool；
Fig. 3 is structural representation of the present utility model。
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further detail。
As Figure 1-3, a kind of backplate plastered for right angle external corner, including two sub-backplates that entirety is rectangular, a long limit of one of them sub-backplate is provided with several projections 1, a long limit of another sub-backplate is provided with several shrinkage pools 2 matched with described projection 1；Two sub-backplates are plugged in together by described projection 1 and shrinkage pool 2, so that the angle of two sub-backplates is 90 °。
As one preferred embodiment, in order to save material, described shrinkage pool 2 is arranged on one piece of sub-backplate being of a size of 2000 × 65 × 15mm, and described projection 1 is arranged on another block and is of a size of on the sub-backplate of 2000 × 50 × 15mm, to be spliced into the equilateral right angle L-shaped of 2000 × 65 × 15mm。
As one preferred embodiment, for the ease of storage, described sub-backplate is spliced by the molecule backplate of two pieces of area equation and forms。
As one preferred embodiment, for the ease of fixing, described projection 1 and the cross section of shrinkage pool 2 are square or circular。
As one preferred embodiment, described sub-backplate is provided with installing hole 3, is used for and wall connecting。
In actually used, follow these steps to operation:
1) two sub-backplates are formed this utility model and are fixed on external corner。
2) sand-lime that weight ratio is 1:3 of rendering concrete and coarse sand on body of wall。
3) this utility model is pulled down, the sand-lime that weight ratio is 1:2 of rendering concrete and coarse sand on external corner。
Above-described embodiment of the present utility model is only for this utility model example is described, and is not the restriction to embodiment of the present utility model。For those of ordinary skill in the field, other multi-form change and variations can also be made on the basis of the above description。Here cannot all of embodiment be given exhaustive。Every belong to apparent change that the technical solution of the utility model amplified out or the variation row still in protection domain of the present utility model。
