Description

A steel pipe stair step

technical field

The utility model relates to the field of stair parts, in particular to a steel pipe stair tread.

Background technique

The steel pipe staircase is a commonly used tool in construction projects. It is used to connect two floors of stairs to facilitate the movement of construction and other personnel. At present, most of the temporary stairs used in engineering are assembled by steel pipes and formwork or scaffolding, and there are also finished vertical passages. The first kind of temporary stairs has problems such as disorganization, poor stability, and unsafety. It is also difficult to assemble. Very inconvenient and often takes a lot of time. The second type of access "stairs" is bulky and heavy, and needs to be hoisted by a crane or a hoist to be used, and cannot be used in the area of a crane or a hoist.

Based on this, the present application is filed.

Contents of the invention

The object of the present invention is to provide a steel pipe stair step with stable structure and stereotypes, which is convenient for temporary stair erection in construction projects, improves the stability of the temporary stair, and ensures the safety of the temporary stair.

In order to achieve the above object, the technical solution adopted by the utility model is: a steel pipe stair step, including a square steel plate and two square tubes, the length of the square tube is adapted to the width of the square steel plate and welded to the wide sides of the square steel plate. At the bottom, one long side of the square steel plate is provided with upward folds, and the other long side is provided with downward folds. Rotary fasteners are respectively welded at the middle part of the two long sides of the square steel plate or at the upward folded edge of the middle part.

The utility model is further configured as follows: the two sides of the downward folded edge are respectively welded to the cross-sections of the square tubes on both sides.

The utility model is further configured as follows: the square steel plate is a stainless steel checkered plate.

The utility model is further configured as follows: the thickness of the square steel plate is 0.5-0.8 cm, and the width of the square steel pipe is 2.2-2.5 cm.

The utility model is further set as: the width of the square steel plate is 15-25cm, and the length is 35-100cm.

The utility model is further configured as: the angle between the upper folded edge and the square steel plate is a right angle or an obtuse angle.

Beneficial effects of the utility model: the utility model stair step is welded by patterned steel plate and square tube, and its structure is small and exquisite, light in weight, stable in structure, and can ensure safe use. The utility model can be used in conjunction with scaffolding, and the rotating fasteners on both sides greatly facilitate the erection and disassembly of temporary stairs, and also make the steps convenient for storage and transportation.

The utility model is simple in structure, low in cost, can carry out quantitative production after the same size, has wide applicability, and can be used in construction projects and similar occasions.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in Figures 1 and 2, a steel pipe stair step includes a square steel plate 1, a left side square tube 4 and a right side square tube 2, and the square steel plate 1 is a stainless steel checkered plate. The left square tube 4 and the right square tube 2 have the same size, the lengths of both are compatible with the width of the square steel plate 1 and are welded to the bottom of the wide sides of the square steel plate 1, and the square steel plate 1 is located on the long side of the rear An upward upper fold 101 is provided, and a downward lower fold 102 is provided on the front long side. A right angle or an obtuse angle is formed between the upper flange 101 and the main body of the square steel plate 1 . The two sides of the downward folded edge are respectively welded to the cross-sections of the square tubes on both sides to form a stable wrapped support structure, which can bear the weight of 2 to 3 adults. The middle part of the two long sides of the square steel plate 1 or the middle part are respectively welded with rotating fasteners at the upper folded edge 101 which is upward.

In this embodiment, the thickness of the square steel plate 1 is 0.5-0.8 cm, and the width of the square steel pipe is 2.2-2.5 cm. Square steel plate 1 width is 15～25cm, and length is 35～100cm.

When in use, it is only necessary to set an appropriate gap according to the user or the actual situation, and fix the steps on the steel pipe of the scaffold through the left fastener 5 and the right fastener 3 to build a steel pipe staircase, which is very convenient to set up, and The structure is solid. After use, you only need to remove and stack the steps through the left fastener 5 and the right fastener 3 (the fastener is rotating, and the position of the head can be adjusted by rotating to make the step stable) and then stored or handling.

Based on the above, the utility model welds the checkered steel plate 1 and the square tube to form a stable step. The step is small in structure and light in weight, which makes the step easy to store and carry while ensuring safe use. And the rotary fasteners on both sides of the checkered steel plate 1 enable it to be used in conjunction with scaffolding, which greatly facilitates the erection and disassembly of temporary stairs. Its structure is simple and its cost is low, so it is worth popularizing.

It can be known from technical knowledge that the utility model can be realized through other implementations without departing from its spirit or essential features. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive. All changes within the scope of the utility model or within the range equivalent to the utility model are included in the utility model.
