Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel ladder used in a construction site. Background Art

[0002] On construction sites, such as those for building houses, highways, bridges, etc., steel ladders and other construction auxiliary equipment are required.

[0003] At present, with the progress of the construction industry, various new concepts such as smart construction sites, green construction sites, and safety and civilization have emerged. In order to realize a modern construction site, construction sites must not only focus on safety and civilization, but also pursue intelligence and greenness. This puts forward new requirements for various measures on site, and innovations are needed in training, supervision, and measures. Among them, safe and civilized construction is the main monitoring object as an important link on site, and new requirements are also put forward for ladders in safe and civilized construction. At present, the traditional steel ladder structure has problems such as poor stability, shaking, and inappropriate step width, and cannot flexibly adapt to the construction needs of buildings at different heights. Utility Model Content

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to propose a steel ladder for use on a construction site, using the following technical solutions:

[0005] A steel ladder for use at a construction site, comprising two brackets arranged in parallel, wherein the lower ends of the two brackets are detachably mounted on a first level, and the upper ends are detachably mounted on a reserved opening of a second level;

[0006] A plurality of angle steels are fixedly arranged between the two brackets, and first right-angle sides of the plurality of angle steels are parallel to the first level to form a plurality of stair flights.

[0007] As a further improvement, each of the above-mentioned stair sections includes two symmetrically arranged angle steels.

[0008] As a further improvement, the distance between the two angle steels forming the above-mentioned stair section is 3 to 5 cm.

[0009] As a further improvement, the upper surface of the first right angle edge is provided with anti-slip grooves.

[0010] As a further improvement, it also includes at least one handrail, which is fixedly arranged above the bracket in parallel through a first connecting member.

[0011] As a further improvement, the first connecting member is vertically welded between the bracket and the handrail.

[0012] As a further improvement, a second connecting member perpendicular to the first level is provided between the bracket and the handrail.

[0013] As a further improvement, the second connecting member extends to the first level and is fixedly connected to the first level via the first base.

[0014] As a further improvement, a second base for fixing to the ground is provided at the lower end of the bracket.

[0015] As a further improvement, a hook for hanging the reserved hole is provided at the upper end of the bracket.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] First, the utility model forms a steel ladder by arranging a number of angle steels between two parallel brackets. The upper end of the steel ladder is hung in the hole reserved for the second-level construction, and the lower end is fixed to the ground through the second base. This structure significantly improves the poor stability of the traditional steel ladder and the shaking during climbing. The overall structure is simple and stable, easy to install, and can flexibly adapt to the construction needs of buildings at different heights.

[0018] Secondly, the staircase of the utility model is composed of two symmetrically arranged angle steels, one right-angle side of the two angle steels is parallel to the first level, and anti-slip grooves are arranged on them, which increases the friction when stepping and reduces the risk of slipping accidents. The interval between the two angle steels is 3 to 5 cm, which increases the step width of the entire staircase, effectively improving the safety of the steel ladder when in use, especially ensuring the safety of construction workers in a humid or dusty construction environment.

[0019] Thirdly, the utility model further comprises at least one handrail fixedly mounted above the bracket in parallel via a first connecting member, the first connecting member being vertically connected between the handrail and the bracket, which can effectively disperse and transmit the force borne by the handrail, thereby improving the stability and durability of the entire staircase. The second connecting member is arranged perpendicularly to the first level, thereby ensuring a more stable fixing point between the staircase and the ground, reducing the risk of the staircase shaking or shifting, and improving the stability of the overall structure.

[0030] like Figure 1-Figure 2 As shown, the present application provides a steel ladder for use at a construction site, comprising two parallelly arranged brackets 1, the lower ends of the two brackets 1 being detachably mounted on a first level 100, and the upper ends of the two brackets 1 being detachably mounted on a reserved opening 201 of a second level 200; a plurality of angle steels 2 are fixedly arranged between the two brackets 1, and the first right-angled sides of the plurality of angle steels 2 are parallel to the first level 100 to form a plurality of stair sections, and each of the plurality of stair sections comprises two symmetrically arranged angle steels 2.

[0031] In a specific embodiment, the first level 100 is the bottom floor of the construction, and the second level 200 is the second floor of the construction. The second floor is provided with a square hole with a side length of 1.5m, forming the above-mentioned reserved hole 201. Before installation, the height of the first level 100 and the second level 200 is measured, and the bracket 1 is calculated and cut according to the measured height, so that the two brackets 1 can be inclined between the first level 100 and the second level 200, and the angle between the first level 100 and the first level 100 is 60°. After the bracket 1 is cut, the angle steel 2 is welded between the two brackets 1, such as Figure 3 As shown, the second right-angled sides of the two angle steels 2 are parallel and oppositely arranged, and the first right-angled sides are flush to form the step surface of the above-mentioned stair section. The angle between the step surface and the bracket 1 is 60°. When the bracket 1 is erected between the first level 100 and the second level 200, the step surface is parallel to the first level 100.

[0032] In a specific embodiment, in order to ensure the stability and durability of the steel ladder, the above-mentioned bracket 1 is a square solid steel pipe, and two angle steels 2 for forming a stair section are fixedly arranged every 0.5m between the two solid steel pipes. The side width of the angle steel 2 is 8cm, and the spacing between the two angle steels 2 is 4cm, that is, the step width of each stair section is 20cm, which makes going up and down the stairs more stable and comfortable, ensuring the safety of construction workers at work. The gap between the two angle steels 2 can filter out small stones dropped during the construction process, further improving safety during use.

[0033] like Figure 4 As shown, the upper surface of the first right-angled side of the angle steel 2 is provided with anti-slip grooves 21, which increases the friction when stepping and reduces the risk of slipping accidents.

[0034] like Figure 1-Figure 2 As shown, at least one armrest 3 is also included, and the armrest 3 is fixedly arranged above the bracket 1 in parallel through a first connecting member 4.

[0035] In a specific embodiment, the upper ends of the two brackets 1 are welded with handrails 3 through first connectors 4, and the first connectors 4 are perpendicular to the brackets 1 and handrails 3, thereby increasing the stability and firmness of the handrails 3. The first connector 4 is an angle steel 2 with a length of 40 cm, and the two ends of the angle steel 2 are respectively welded to the sides of the bracket 1 and the handrail 3 that are close to each other.

[0036] like Figure 1 and Figure 2 As shown, a second connecting member 5 perpendicular to the first level 100 is provided between the bracket 1 and the handrail 3. The second connecting member 5 extends to the first level 100 and is fixedly connected to the first level 100 through a first base 51.

[0037] In a specific embodiment, the second connecting member 5 is an angle steel 2, one of the right-angled sides of which is welded to the side of the above-mentioned bracket 1 and the handrail 3, and a square steel plate as the first base 51 is welded to the lower end. The square steel plate is provided with a plurality of bolt holes so that it can be fixed to the first level 100 by bolts; in another embodiment, if the first level 100 is an earthen site, a ground nail can also be set at the lower end of the above-mentioned square steel plate, and the fixing effect can be achieved by inserting the ground nail into the first level 100.

[0038] like Figure 1 and Figure 2 As shown, the upper end of the bracket 1 is provided with a hook 12 for hanging on the above-mentioned reserved hole 201, and the lower end is provided with a second base 11 for fixing on the ground.

[0039] In a specific embodiment, the upper end of the bracket 1 is beveled at 30°, a steel bar is welded on the cut surface, and the tail end of the steel bar is bent away from the cut to form a hook 12. When the bracket 1 and the first level 100 are erected between the first level 100 and the second level 200 at an angle of 60°, the steel bar at the upper end of the bracket 1 can fit the inner wall of the reserved hole 201, and the length of the steel bar is less than the length of the upper and lower edges of the reserved hole 201, that is, when the hook 12 is hung on the upper edge of the reserved hole 201, the upper end of the bracket 1 abuts against the inner wall of the reserved hole 201. After the length of the bracket 1 is determined, the steel ladder is pre-installed through the hook 12 structure, making the overall installation more convenient.

[0040] In a specific embodiment, the structure of the second base 11 is similar to that of the first base 51 , both of which are square steel plates, and can be fixedly connected to the first level 100 by bolts, ground nails, etc.

[0041] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
