In addition, the steel pipe stair is temporary, flexible in erection and convenient to disassemble and assemble, but poor in skid resistance, and easily causes the slip and fall accidents of constructors.
Disclosure of Invention
The utility model aims at providing a fastener formula combination steel pipe stair can satisfy the steel pipe stair setting of not co-altitude requirement to supply the current outer scaffold frame from top to bottom that the workman can be safe convenient of executing.
In order to achieve the above purpose, the utility model adopts the following technical scheme to solve:
the utility model provides a fastener formula combination steel pipe stair, includes steel bar pedal, bracing piece, cross fastener, its characterized in that: the two ends of the steel bar pedal are connected with the supporting rods through the cross fasteners, the steel bar pedals with corresponding quantity are arranged according to different use heights, the supporting rods are erected on the outer scaffold, and the cross fasteners are also adopted for connection.
The steel bar pedal is a rectangular steel bar framework and is formed by welding a plurality of pieces of first-level steel, two ends of the steel bar pedal are respectively welded with a 250mm long short steel pipe serving as a connecting part with the supporting rod, and the short steel pipe is consistent with the steel pipe of the external scaffold in model.
The bracing piece is steel pipe for the outer scaffold frame, and length is by using the height-dependent.
The cross fastener is used for connecting the components.
Preferably, one end of the support rod is lapped on the upper-layer horizontal rod of the scaffold, and the other end of the support rod is lapped on the lower-layer horizontal rod and fixed by the cross fastener.
Preferably, the angle between the reinforced pedal and the supporting rod can be adjusted by adjusting the tightness of the cross fastener.
Preferably, the support rods are horizontally placed, the cross fasteners are connected to the horizontal rods of the scaffold, and the steel bar pedals are adjusted to be in the horizontal position to form the temporary springboard.
The utility model discloses possess following advantage:
1. the whole device has simple structure and good anti-skid performance and can be made of temporary materials on the construction site.
2. The connecting device is connected by the fasteners, can be disassembled and repeatedly recycled, and has small labor intensity in installation and disassembly and simple and convenient and rapid operation.
3. Can adjust the angle of setting up and the height of steel pipe stair according to the in-service use needs, also can regard as interim springboard to use.

In the figure, 1, a steel bar pedal, 2, a support rod, 3, a cross fastener and 4, an external frame hand rack are arranged.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
The first embodiment is as follows: firstly, according to the erection condition of the external scaffold 4, the position of the steel pipe stair and the erection angle and height of the steel pipe stair are confirmed, and the length of the required support rod 2 and the number of the steel bar pedals 1 and the cross fasteners 3 are calculated. Wherein, the steel bar pedal 1 is manufactured by welding a first-level steel bar and a steel pipe on a construction site.
After having made steel bar pedal 1, with a certain amount of steel bar pedal 1 and bracing piece 2, cross fastener 3 transports to 4 access ways of outer scaffold frame department, as shown in fig. 5, earlier put two bracing pieces 2 respectively to one side in the pole setting of 4 both sides of outer scaffold frame inboard during the installation, both ends take respectively on the horizontal pole of lower floor on outer scaffold frame 4 about bracing piece 2, link together bracing piece 2 and horizontal pole with cross fastener 3, take respectively on two bracing pieces 2 with the short steel pipe at 1 both ends of steel bar pedal immediately, adjust whole being in the horizontal position of steel bar pedal and connect with cross fastener 3, and according to this order by low to high all install remaining steel bar pedal 1 go can.
The installation of all fastener type combined steel pipe staircases is as described above, and the description is omitted here.
The steel pipe stair of installation need inspect whether firm with being connected of bracing piece 2 of steel bar footboard 1, and when constructor trampled, whether steel bar footboard 1 can rotate, should in time screw up the reinforcement to cross fastener 3 if appear rotating.
When the outer scaffold frame finishes using and enters the dismantling stage, the steel pipe stairs are dismantled synchronously, the cross fasteners 3 for connecting the steel bar pedals 1 and the supporting rods 2 are dismantled by a wrench, and then the steel bar pedals 1 are taken down one by one to be bound together and transported to the ground. The dismounting of the supporting rod 2 is consistent with the dismounting step of the reinforced pedal 1.
Example two: when the scaffold frame need not pass from top to bottom, the passway is to the current formation hindrance of same floor scaffold frame, can place the horizontal horizon bar below at the passway both ends with 2 levels of bracing piece this moment, adjust the elasticity of cross fastener simultaneously, with the angle modulation of steel bar footboard 1 and bracing piece 2 zero, let steel bar footboard 1 side by side in the horizontal direction promptly, be connected bracing piece 2 and horizontal horizon bar with cross fastener 3 immediately, also available a plurality of cross fasteners 3 link together bracing piece 2 and the vertical horizon bar of passway both sides. After the installation is completed, a temporary springboard is formed for the passage of the applicator.
The removal of the temporary springboard is the same as the first embodiment, and the description is omitted here.
All scaffold application places where the springboards need to be laid can adopt the temporary springboards of the embodiment as a passing mode.
The construction attention problem is as follows: when the outer scaffold is in construction operation, a safety rope is tied, the other end of the safety rope is buckled on the outer scaffold steel pipe, a safety helmet is worn, and a helmet belt is tied; regularly checking whether the steel pipe stair is firm or not at intervals and whether the steel pipe stair is loose or not; the disassembled parts of the steel pipe stairs are required to be intensively placed or put into a warehouse for storage.
