Yancheng hemlock wood square building wooden square engineering wooden square wood manufacturer

Description :

　　The mold for forming concrete structures or reinforced concrete structures of Junsheng Wood Industry consists of panels and support systems (including dragon bones, trusses, small beams, etc., as well as vertical support structures), connecting accessories (including bolts, connecting buckles, formwork surfaces and supporting components, and connecting accessories between supporting components).

　　Templates are divided into steel templates, bamboo plywood, wooden templates, and plastic templates according to materials.

　　Bamboo plywood is generally disposable, while other templates can be coated with release agents and template paint to extend their lifespan and cast high-quality pillars.

　　Throughout history, people have never lacked the use of wood as a raw material. Looking back at China's 5000 year cultural history, it is not difficult to find that the use of wood has not been limited since we formed our own unique culture. So, what are the common uses of building wood in daily life?

　　In fact, in daily life, the use of building timber is very extensive. As long as one pays attention to observation in daily life, it is not difficult to discover this. Based on the research on raw materials in the timber market, the following summary has been made.

　　Construction template axis displacement

　　1. Phenomenon of displacement of building formwork axis

　　When removing the building formwork after pouring concrete, it was found that the actual positions of the columns and walls were offset from the axis of the building.

　　2. Analysis of the reasons for the displacement of the axis of the building formwork

　　(1) Insufficient attention to sample preparation or unclear technical disclosure, resulting in the assembly of building formwork components not being in place according to regulations.

　　(2) Axis measurement results in errors.

　　(3) The root and top of the building formwork for walls and columns are not properly positioned or limited, and the deviation is not corrected in a timely manner, resulting in cumulative errors.

　　(4) When supporting the formwork, horizontal and vertical lines were not drawn, and there were no vertical verticality control measures.

　　(5) The stiffness of the building formwork is poor, and there is no horizontal tie rod or the spacing between horizontal tie rods is too large.

　　(6) Uneven and symmetrical feeding during concrete pouring, or excessive lateral pressure caused by one pouring height, resulting in the deviation of the building formwork.

　　(7) Improper or loose use of tension bolts, top supports, and wooden wedges can cause axis deviation.

　　Building formwork is the mold shell and support formed by pouring concrete. According to the properties of the materials, it can be divided into building formwork, building plywood, laminated board, multi-layer board, double-sided adhesive, double-sided laminated building formwork, etc. Architectural formwork can be divided into cast-in-place concrete formwork, pre assembled formwork, large formwork, and jumping formwork according to construction process conditions.

　　Composite steel formwork is a new type of formwork in modern formwork technology that uses steel instead of wood. It has the advantages of strong universality, easy assembly and disassembly, and multiple turnover times. It can be used for the construction of cast-in-place reinforced concrete structures. It can be assembled into large formwork for beams, columns, walls, and floor slabs according to design requirements in advance, lifted into place as a whole, or disassembled in bulk.
