Background technique

In the construction industry, the construction of prefabricated stairs is a new construction technology, and the support of prefabricated ladder beams plays a vital role in the installation and construction of prefabricated stairs. If the prefabricated ladder beam support system collapses, it may cause a great safety accident. At the same time, the flatness of the prefabricated ladder beam controls the installation accuracy of the prefabricated stairs. Therefore, it is necessary to ensure the bearing capacity of the prefabricated ladder beam support system, and to ensure the flatness of the prefabricated ladder beam. If the traditional steel pipe frame is used for support, its main defects are as follows: ① There is no supporting part at the lower part of the steel pipe frame, which makes it difficult to erect and poses a great safety hazard. ②The steel pipe frame elevation cannot be adjusted twice after leveling once.

A diagonal brace (9) is provided on the outside of each column (2), and the upper end of the diagonal brace is connected to the upper end of the corresponding column (2) through a first bolt (10); There is a one-to-one correspondence between the diagonal braces (9), and an n-shaped limiting card slot (11a) is formed at both ends of the bottom surface of the limiting card plate, and one of the n-shaped limiting card slots (11a) is stuck on the diagonal brace (9) Outside the second bolt (12) at the bottom, another n-shaped limiting slot (11a) is stuck outside the third bolt (13) corresponding to the lower end of the column (2).

In the above technical solution, the utility model adopts welding strength, which has high structural strength and good safety. When in use, by turning the four screw rods (5), the two leveling support plates (8) can be placed in the same horizontal plane, so that the prefabricated ladder beam (Y) can be supported on the two leveling support plates (8), And the leveling can also be carried out multiple times by the screw rod (5). In addition, the supporting strength can be effectively enhanced and overturning can be prevented by arranging the detachable limit clamping plate (11) and the diagonal brace (9).

By adopting the above technical scheme, the utility model has high welding strength, high structural strength, good safety, and can be leveled many times to support the prefabricated ladder beam well, and can be effectively enhanced by setting detachable limit clamps and diagonal braces. Supporting strength, reliably prevents tipping over.

In order to facilitate material selection and take structural strength into account, the crosspiece (1), column (2), beam (3) and leveling support plate (8) are all made of channel steel.

As a preference, the notch of the leveling support plate (8) faces downward.

Beneficial effects: the utility model has high welding strength, high structural strength, good safety, can be leveled multiple times, supports the prefabricated ladder beam well, and can effectively enhance the support strength by setting detachable limit clamps and diagonal braces , reliably prevent overturning.
