Embodiment

[0016] Embodiment: The U-shaped steel 1 of the present invention is made of Q345 material, and the strength is significantly improved. The U-shaped steel 1 is a cold-formed thin-walled structure, which is processed by a forming process, and the mold is cold-formed, which embodies the characteristics of light weight and high strength of steel; The upper and lower flanges 8 of the U-shaped steel 1 are curled inwardly, and a row of punched connecting holes 4 are arranged on the upper and lower sides of the web of the U-shaped steel 1, and a row of connecting holes 4 is arranged between the upper and lower connecting holes 4. The heavy round hole 9, the opening reduces the weight while ensuring the strength, reduces the consumables, and reduces the cost, while the round hole is to prevent stress concentration; in order to improve the local stability of the flange, on the U-shaped steel 1, Reinforcement plates 10 are arranged at equal intervals between the lower flanges 8; the dista...

Abstract

The invention discloses a supporting joist for a building. The supporting joist comprises U-shaped steel, connecting sleeves and a connecting part, wherein a row of punched connecting holes are formed in each of the upper part and the lower part of a web plate of each piece of U-shaped steel at equal intervals; and two pieces of back-to-back U-shaped steel are connected to form a double U-shaped steel supporting joist body by penetrating bolts for the connecting sleeves into the connecting holes; the connecting part is a rectangular box, a row of second connecting holes which are adapted to the connecting holes in the aspect of intervals and sizes are formed in each of the upper part and the lower part of the connecting part in a front-back penetrating manner, and the connecting part is put between the two pieces of back-to-back U-shaped steel and connected with the second connecting holes to lengthen the double U-shaped steel supporting joist body by penetrating bolts for the connecting sleeves into the connecting holes. The supporting joist has the advantages of light weight, high strength, good stability, convenience in assembly and the like, the mechanical properties such as strength, rigidity and the like are improved, the supporting joist is flexible, simple and convenient to operate, and the production cost is low.

Description

technical field [0001] The invention relates to a formwork supporting flute for building, in particular to a double U-shaped steel supporting flute. Background technique [0002] Formwork support corrugated is an important tool in the process of building construction. In cast-in-place concrete structure engineering, formwork engineering occupies a considerable proportion in the cost of concrete structure engineering, engineering labor and construction period. Formwork technology directly affects the quality of engineering construction, Therefore, formwork engineering is an important factor to promote the development of building technology, and formwork support is the most important thing. At present, the commonly used support flutes mainly include wood flute and steel flute. With the development of the construction industry, there are more requirements for the mechanical properties, production efficiency, and economic benefits of the support flute. The strength, stiffness an...
