technical field

The utility model relates to a fastener type combined steel pipe staircase, which belongs to the field of building construction.

Background technique

The existing ways of passing the upper and lower floors of the outer scaffolding usually include profiled steel inclined ladders, ramps, etc. Although the passages of profiled steel inclined ladders and ramps are convenient, the engineering volume is large and the erection is complicated, which is not conducive to repeated use. In addition, there are temporary steel pipe stairs, which are flexible to erect and easy to disassemble and assemble, but have poor sliding resistance, which may easily cause construction workers to slip and fall.

SUMMARY OF THE INVENTION

The purpose of the utility model is to provide a fastener type combined steel pipe staircase, which can meet the requirements of different heights to set the steel pipe staircase, so that the construction personnel can safely and conveniently pass the outer scaffolding up and down.

For achieving the above object, the present utility model adopts the following technical solutions to solve:

A fastener-type combined steel pipe staircase, comprising steel treads, support rods, and cross fasteners, characterized in that: cross fasteners are used to connect the two ends of the steel reinforcement pedals with the support rods, and a corresponding number of Reinforced pedals and support rods are erected on the outer scaffolding, which are also connected by cross fasteners.

The reinforced pedal is a rectangular reinforced skeleton, which is welded by several first-grade steels, and a short steel pipe with a length of 250 mm is welded at each end as the connecting part with the support rod. The model of the short steel pipe is the same as that of the outer scaffolding steel pipe.

The support rod is a steel pipe for outer scaffolding, and the length is determined by the height of use.

The cross fasteners are cross fasteners for outer scaffolding, which are used for connection between various components.

Preferably, one end of the support rod is draped on the upper horizontal horizontal rod of the scaffold, and the other end is draped on the lower horizontal horizontal rod, and is fixed by the cross fastener.

Preferably, the angle between the steel bar pedal and the support rod can be adjusted by adjusting the tightness of the cross fastener.

Preferably, the support rod is placed horizontally, connected to the horizontal rod of the scaffold with the cross fastener, and the steel bar pedal is adjusted to a horizontal position to form a temporary springboard.

The utility model has the following advantages:

1. The whole device has a simple structure and good anti-skid performance, and can be made of materials temporarily at the construction site.

2. It is connected by fasteners, which can be disassembled and used repeatedly, and the labor intensity of installation and disassembly is small, and the operation is simple and fast.

3. The erection angle and height of the steel pipe staircase can be adjusted according to the actual needs, and it can also be used as a temporary springboard.

Detailed ways

The present utility model will be described in further detail below in conjunction with the accompanying drawings and embodiments.

Embodiment 1: First, according to the erection of the outer scaffolding 4, confirm the position of the steel pipe staircase and its erection angle and height, and calculate the required length of the support rod 2 and the number of steel treads 1 and cross fasteners 3. Among them, the reinforced pedal 1 is made by welding first-grade steel bars and steel pipes on the construction site.

After the rebar pedals 1 are made, a certain number of rebar pedals 1, support rods 2, and cross fasteners 3 are transported to the passage opening of the outer scaffold 4. As shown in Figure 5, the two support rods 2 are first inclined respectively during installation. Put it on the inside of the vertical rods on both sides of the outer scaffold 4, and the upper and lower ends of the support rod 2 are respectively placed on the horizontal horizontal rods on the upper and lower layers of the external scaffold 4. Use the cross fasteners 3 to connect the support rod 2 and the horizontal horizontal rod together. 1. The short steel pipes at both ends are placed on the two support rods 2 respectively. After adjusting the steel pedal 1 to be in a horizontal position as a whole, connect it with cross fasteners 3, and install all the remaining steel pedals 1 from low to high in this order.

The installation of all fastener-type composite steel pipe stairs is as described above, and will not be repeated here.

Installed steel pipe stairs need to check whether the connection between the steel tread 1 and the support rod 2 is firm, and whether the steel tread 1 will rotate when the construction workers step on it.

When the outer scaffolding is used and enters the dismantling stage, the steel pipe stairs will be dismantled synchronously. Use a wrench to first remove the cross fasteners 3 connecting the steel treads 1 and the support rods 2, and then remove the steel treads 1 one by one. ground. The disassembly of the support rod 2 is the same as the disassembly steps of the reinforced pedal 1.

Embodiment 2: When the scaffolding does not need to pass up and down, the passageway will hinder the passage of the scaffolding on the same layer. At this time, the support rod 2 can be placed horizontally under the horizontal horizontal rods at both ends of the passageway, and the tightness of the cross fasteners can be adjusted at the same time. Adjust the angle of the rebar pedal 1 and the support rod 2 to zero, that is, let the rebar pedals 1 be side by side in the horizontal direction, and then use the cross fastener 3 to connect the support rod 2 to the horizontal horizontal rod, or use several cross fasteners 3 to support The rod 2 is connected with the longitudinal horizontal rods on both sides of the channel opening. After the installation is completed, a temporary springboard is formed for the construction personnel to pass.

The removal of the temporary springboard is the same as that in the first embodiment, and will not be repeated here.

All scaffolding application sites that need to lay a springboard can use the temporary springboard of this embodiment as a way of passage.

Construction precautions: During the construction of the outer scaffolding, the safety rope must be fastened, and the other end of the safety rope should be fastened to the steel pipe of the outer scaffolding. Looseness; disassembled steel pipe stair parts should be placed centrally or stored in a warehouse.
