Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a standardized steel platform for assembled construction. Background Art

[0002] Traditional construction stairs generally use steel pipe fasteners to set up external protective railings, small crossbars as steps, and wooden formwork on top to form a stable access system. With the popularization and promotion of prefabricated buildings, prefabricated stairs are increasingly used in building construction projects. This poses a problem in actual on-site construction: Since the construction floor and the next floor are prefabricated stairs that are hoisted later, how can personnel go up to the construction floor for construction? Since the traditional steel pipe uprights may not be able to take root when they are erected, it is very necessary to seek a standardized integrated steel platform to meet the needs of construction site access. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a standardized steel platform for prefabricated construction, including an outer frame and a step ladder, the outer frame is a cubic frame structure, four first cross braces are welded at the same height in the four side facades of the outer frame, the plane enclosed by the four first cross braces constitutes an operating layer, the operating layer divides the outer frame into an upper protective part and a lower supporting part, two second cross braces are welded and fixed in the operating layer, and the space between the two second cross braces is exposed to allow the step ladder to pass through, the step ladder is welded at an angle inside the outer frame, and passes through the operating layer between the two second cross braces.

[0005] Furthermore, the outer frame, the first cross brace and the second cross brace are welded from 70×70×3mm square steel pipes, and the steps of the step ladder are made of 3mm thick patterned steel plates.

[0006] Furthermore, a plurality of first inner supports which are longitudinally evenly spaced are welded inside the operating layer and the bottom surface of the outer frame, and a first steel mesh is laid inside the operating layer.

[0007] Furthermore, the first inner support is made of a 40×40×3mm square steel tube.

[0008] Furthermore, a plurality of second inner supports are welded inside the protective part of the outer frame, and the second inner supports are staggered vertically and horizontally to enhance the strength of the protective part, and a second steel mesh is welded and fixed inside the protective part.

[0010] Furthermore, a third inner support with equal longitudinal spacing is welded to the bottom surface of the support portion of the outer frame, and vertical supports and diagonal supports are welded inside the vertical surface of the support portion to enhance the strength of the support portion.

[0011] Furthermore, the third inner support, vertical support and diagonal support are all made of 40×40×3mm square steel tubes.

[0012] After adopting such a design, the utility model has at least the following advantages:

[0014] 2. Use steel mesh to make hard protection, provide horizontal protection for temporary stair opening construction, and improve the safety of on-site construction;

[0015] 3. It has the functions of both access and operating frame, which can provide construction workers with access to the upper and lower working surfaces before the prefabricated stairs are installed.
