Background
With the decrease of the total urban land supply and the rapid rise of the land price, the proportion of high-rise buildings in the building engineering is continuously rising, and the erection of scaffolds and frontier defense guardrails as a very important ring in the construction becomes more and more importantThe technical subject is to be solved. The pipe adopted by the scaffold and the adjacent edge guard fence at the present stage is basically made of Q235 steel
The steel pipe of (2) has the following problems in the erection using the steel pipe:
1. the steel pipes are uneven in quality level, the wall thickness is generally thin, the steel pipes are easy to rust, pits appear on the surface, and the steel pipes are easy to bend, flatten the pipe wall and the like after being repeatedly used, so that the bending resistance and the compression resistance of the steel pipes are reduced, and the long-term bearing capacity is influenced;
2. the steel pipe is heavy in self weight, the load of the steel pipe is considered when the scaffold is erected, a large amount of resources are consumed for eliminating the influence of the load of the steel pipe, and meanwhile, the erection labor intensity is high, and the construction progress is influenced;
SUMMERY OF THE UTILITY MODEL
For solving prior art's shortcoming and not enough, provide a novel structure building scaffold and face limit protection and use the pipe to can solve the steel pipe and cause the problem of the big influence construction progress that causes of bending resistance, resistance to compression decline and dead weight because of self defect and used repeatedly.
For realizing the utility model discloses the purpose provides a novel structure building scaffold and face limit for protection pipe, including by interior and inlayer pipe, intermediate layer pipe and the functional layer that sets gradually outward, be provided with the enhancement layer between inlayer pipe and intermediate layer pipe, intermediate layer pipe and the functional layer, the intermediate layer pipe is hollow sandwich structure, is provided with a plurality of connection ribs along its axis equipartition in the intermediate layer pipe.
As a further improvement of the scheme, the inner layer pipe and the middle layer pipe are both compounded by continuous high-performance fibers and resin, and the functional layer is composed of resin.
As a further improvement of the scheme, the reinforcing layer is a cloth woven by continuous high-performance fibers.
As a further improvement of the above solution, the number of the connecting ribs in the intermediate layer pipe is at least 3.
The utility model has the advantages that:
compared with the prior art, the utility model provides a novel structure building scaffold and face frontier defense and use the pipe, the main part of body is formed by resin and high performance fibre complex, and density is 1/6 of steel pipe density only, makes the body dead weight greatly reduced; meanwhile, the reinforcing layer in the pipe body is woven by continuous high-performance fibers, so that the bending resistance and the pressure bearing capacity of the pipe are greatly improved, and meanwhile, the connecting ribs in the middle layer and other parts are combined into a unique I-shaped structure, so that the self weight of the pipe body is effectively reduced on the basis of enhancing the bending resistance and the pressure resistance of the pipe body; in addition, the material of the functional layer on the outermost side can effectively prevent the tube body from being corroded, and the long-term bearing capacity of the tube body is guaranteed. The problems that the construction progress is influenced by bending resistance, pressure resistance reduction and self weight caused by self defects and repeated use of the steel pipe are solved by the advantages.
