Description

Just, dismantle scaffold connecting piece that can be used to high big template Technical Field The invention relates to the technical field of constructional engineering, in particular to a scaffold connecting piece convenient to detach, which can be used for a high and large template. Background With the development of modern society, modern buildings break through new heights continuously in height and span, so that the requirements on bearing capacity of the buildings are higher and higher, and the application technology of high formwork is also increased. In the construction of concrete engineering structures, aiming at formwork engineering and supporting systems, the height is set up to be 8m or more, the span is set up to be 18m or more, the total construction load is 15kN/m 2 or more, and the concentrated line load is 20kN/m or more, and the construction method belongs to a high and large formwork supporting system. Therefore, the formwork engineering is one of important factors affecting the safety quality of the whole engineering, and serious collapse accidents occur in the concrete pouring process of the formwork support system, so that serious quality safety accidents are necessarily caused, and life and property safety is endangered. By adopting the traditional cast-in-situ box girder template, the cast-in-situ box girder template is high in surface smoothness, convenient to assemble and easy to disassemble, but the cast-in-situ box girder template bracket is required to be arranged on a foundation which is reinforced and has enough strength, and the foundation surface is required to be flat, so that the requirement on the construction environment is high. In the formwork support system, a scaffold connecting piece which can be adopted for high and large formwork construction is provided with a fastener type steel pipe scaffold, the processing, erection and dismantling of the bracket are simple, the length and the angle of a steel pipe can be adjusted randomly, the erection is flexible, the applicability is good, but the steel pipe is made of Q235B common carbon steel, a rod piece is easy to corrode, periodic paint filling is needed, the turnover is poor, the random interception phenomenon of a long steel pipe is common, and the material loss rate is high. From the mechanical failure mechanism, the upright rod is used as a main stress member of the scaffold and mainly bears axial pressure. When the vertical rod is positioned on the side rod or the angle rod, the axial compression gradually becomes eccentric compression, a larger bending moment value is generated, the vertical rod starts to be unstable, and finally the rod piece loses stability. The bolts of the fasteners are used as the support for supporting the horizontal rods, the counterforce of the support is gradually increased, and the bolts are in welded connection with the horizontal support, so that the bolts on two sides of the horizontal support bear the shearing force, and if the welding quality is low, the welding line bearing capacity at the joint of the horizontal rods and the bolts is low, and the shearing damage of the bolts occurs. Therefore, how to connect the scaffold can ensure the stability of the scaffold, reduce the damage caused by eccentric compression of the vertical rod or shearing of the bolt, and ensure the convenience of installation and disassembly of the scaffold, and is the subject of the research of the invention. The technical erection and design of the high and large formwork support system are not standardized in China, and the formwork support frame can cause the loss of the high and large formwork support frame due to the fact that the formwork support frame is repeatedly turned, transported and used in practical engineering application, so that the high and large formwork support frame is erected in practical engineering in a more-than-half experience semi-theoretical mode, although the experience of the existing design and constructors is sufficient, the scientific theoretical basis is lacking, the complexity of the high and large formwork is completely insufficient only by virtue of construction experience, namely, if the complex and special formwork system is encountered, the design and constructors cannot grasp the key points of the complex and large formwork support frame, and the high and large formwork accident frequency is caused.
