Description
Technical Field
The invention relates to a method for fixing I-steel, in particular to a method for fixing overhanging I-steel.
Background
In the early 80 s of the last century, various types of scaffolds such as door type scaffolds, bowl-buckled scaffolds and the like are introduced from foreign countries in China. The door type scaffold has been widely applied in many domestic projects to obtain better effect, and the door type scaffold is not widely popularized and applied due to the product quality problem of the door type scaffold. A lot of door type scaffold production plants are built in China, and most products are processed according to the drawings of foreign merchants. The bowl-buckled scaffold is the most popularized scaffold in novel scaffolds, but the use range is not wide, and the scaffold is only applied in partial regions and partial projects.
With the appearance of a large number of modern large-scale building systems in China, the fastener type steel pipe scaffold can not meet the requirement of building construction development, and the rapid development, popularization and application of the novel scaffold are urgent. Practice proves that the novel scaffold is safe and reliable in construction and high in assembly and disassembly speed, the steel consumption of the scaffold can be reduced by 33%, the assembly and disassembly efficiency is improved by more than two times, the construction cost can be obviously reduced, and the construction site is civilized and neat.
The outer scaffold is generally fully built along the outer wall surface of a building, is convenient for structure and decoration construction, but consumes materials and labor, and has large one-time investment and long construction period. These disadvantages are not obvious in the construction of multi-storey buildings, are prominent in the construction of high-storey buildings, and sometimes even cannot be applied. Since the outer scaffolding is fully erected from the ground, when the construction is carried out to the upper part, the lower scaffolding is still required to be kept, and the function of the lower scaffolding is only to transfer the load of the upper working layer to the foundation and is not necessary for the construction operation. When the height of the house is very high, the height of the scaffold which is fully built exceeds the allowable building height of the scaffold; many high-rise bodies are provided with skirt houses around, and the scaffolds of the body structures cannot be directly supported on the ground; sometimes, in order to reach the construction period, the backfill soil at the position of the level 0 is not backfilled, and the outer scaffold cannot be supported on the ground even if the main structural engineering is required, so that the floor type outer scaffold cannot be applied to the construction period. In the construction of high-rise buildings, the scaffold which is not in a floor type is adopted more generally in recent years, but most of the reinforcement measures of the overhanging scaffold are complex to operate, complex to assemble and disassemble and high in measure cost.
The known methods of reinforcing cantilevered scaffolding thus suffer from the inconveniences and problems described above.
Disclosure of Invention

Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
The invention relates to a fixing method of cantilever I-shaped steel, which is characterized in that a reinforcing measure is formed by a detachable steel sleeve 2 and a U-shaped bolt 1 with an embedded diameter of 18. When the floor slab is poured, the wall thickness of the steel sleeve is 0.8, and the steel sleeve is embedded on the floor slab, and the length of the steel sleeve is 20cm higher than that of the poured floor slab 5; the steel bar is larger than the embedded steel bar with the diameter of 18, the steel bar can penetrate into the embedded steel bar, the embedded steel bar is fixed by angle steel and an anchoring bolt, and the embedded steel bar is locked by a connecting steel plate 3 and a nut 4, so that the problem of strength and rigidity is solved. Fig. 1 is a schematic view of a fixing device according to an embodiment of the present invention.
The cantilever I-steel fixing method has the advantages of substantial characteristics and obvious technical progress, and the cantilever I-steel fixing method is simple in reinforcing measure and operation, convenient to assemble (disassemble), practical and good in effect. By utilizing the national measures, the quality of the longitudinal stressed steel bar of the large-span large-diameter column is greatly improved; workers can master quickly in the operation process, the working efficiency is improved, and the safety is guaranteed; because the device can be repeatedly used, the construction cost is saved.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention.
