Problems solved by technology
[0005] The purpose of the present invention is to provide a roof girder without vertical poles to support the main beam of the roof. It is necessary to solve the technical problems that the existing roof formwork supports are intricately supported, and the interlacing of horizontal bars and vertical bars seriously affects the convenience of construction, and it is not beautiful and difficult to adjust; It is necessary to solve the technical problems of serious material waste and labor-intensive materials; it is also necessary to solve the technical problems of heavy assembly and construction of support structures, low construction efficiency, and low safety and reliability.

Embodiment Construction
[0044] Examples see Figure 1~5 As shown, the roof girder without vertical poles is placed between the poured walls on both sides. The roof girder is in the form of a truss as a whole, including the truss in the middle and the fixed supports connected to the two ends of the truss 1. The top of the truss is kept at the same height as the top of the fixed support. The truss includes the upper chord 3 of the profile, the side web of the round steel 4, the middle web of the round steel 5, the lower chord of the round steel 6, and the connecting piece of the profile 2 and angle steel bolt 7, the two ends of the upper chord 3 of the profile are respectively fixedly connected to a profile connector 2, and one end of the profile connector 2 and the fixed support 1 is inserted through the angle steel bolt 7, and the other end of the fixed support 1 embedded in the wall.
[0045] see Figure 6~7 As shown, the upper chord 3 of the profile is formed by cold bending of a thin steel plate...

A roof main beam without poles is placed between the walls that have been poured on both sides. The top is kept at the same height as the top of the fixed support. The truss includes a profile top chord, a round steel side web rod, a round steel middle web rod, a round steel bottom chord, a profile connecting piece and an angle steel bolt that are connected as a whole. The profile top chord The two ends of the fixed support are respectively connected with a profile connecting piece, the profile connecting piece and one end of the fixed support are inserted through angle steel bolts, and the other end of the fixed support is embedded in the wall. The invention can be suitable for the horizontal support of different building structure types. The main beam takes root on the already poured wall through the fixed support, which ensures the strength and rigidity of the roof formwork and the surface flatness of the formwork panel, and greatly increases the construction of the lower part of the roof formwork. The operating space can be widely used in the construction of building roofs and the erection of temporary platforms.
Description
technical field [0001] The invention relates to a building formwork support, in particular to a main girder supported by no vertical rod in roof construction in formwork engineering. Background technique [0002] In recent years, my country's building formwork industry has developed rapidly, especially today with the increasing development of high-rise buildings, formwork engineering has also become a large and extensive part of construction engineering. Building a conservation-oriented society and developing a low-carbon economy are major policies for our country based on today and facing the future, and the development of low-carbon energy-saving and consumption-reducing products is in line with policy requirements. Due to its own characteristics, the construction industry has always been an industry with high carbon consumption and large material consumption. The use of new technologies, new materials and new products that are energy-saving, environmentally friendly and l...
