Designed an assembled steel construction stair, include: a bent side beam, a step, a T-shaped connecting piece and a flitch. The utility model provides a can recycle, transport convenient assembled steel construction stair, assembled steel construction stair can all dismantle and transport for the part, accomplishes the equipment fast at the job site, and partial part can manifold cycles use, has the significance to improving steel construction stair conveying efficiency and reducing use cost.
Description
Technical Field
The utility model belongs to the technical field of steel construction stair, concretely relates to assembled steel construction stair.
Background
The main effect of stair lies in reducing the degree of difficulty that people ascended a height, highly can realize easily ascending a height through setting up reasonable marking time, and traditional stair adopt concrete placement to form mostly, nevertheless because steel structure stair installation, dismantlement are convenient, increase by a wide margin at the quantity in the place of ascending a height temporarily, especially ascend a height in the building site temporarily facility basic whole be steel structure stair, not only ann tears the convenience open, but also can reuse.
The feedback is good in most use experience of present common steel structure stair, but still the following outstanding problem exists to different extent: (1) the whole is welded into a whole, so that the carrying, loading and unloading, installing and dismounting difficulties are high; (2) the integrated structure has low repeated utilization rate, can not be recycled when the height of the building changes, and has serious material waste; (3) the positioning of the welding points in the machining process is complex, and the machining quality cannot be guaranteed.
Therefore, the utility model discloses to above-mentioned steel construction stair transportation with ann tear open the problem that faces and develop an assembled steel construction stair, to improving steel construction stair cyclic utilization, reduce the transportation degree of difficulty and have the significance.
Disclosure of Invention
The utility model aims at providing a safe, practical assembled steel construction stair provides the guarantee for improving steel construction stair cyclic utilization. Assembled steel construction stair can realize the function through factory prefabrication and field erection, can eliminate the great, the difficult obstacle of transportation of traditional integral type steel construction stair volume, and it is marked time and the equal ability of connecting piece homoenergetic uses interchangeably simultaneously, has good economic benefits.
In order to achieve the purpose, the utility model adopts the following design scheme:
an assembled steel structure staircase, as shown in fig. 1, comprising: a bent side beam, a step, a T-shaped connecting piece and a flitch.
The process of the utility model is as follows:
the side rail of bending, its characterized in that: the steel plate bending device is formed by bending a steel plate, the cross section of the steel plate bending device is of a U-shaped structure, as shown in fig. 2, grooves are formed in two ends of the steel plate bending device, the ground side is overlapped with the wall surface, the wall surface side is overlapped with the flitch plate, multiple groups of round holes are uniformly distributed in the bending side beam, and each group of four round holes are used for mounting T-shaped connecting pieces.
The step is characterized in that: the foot anti-skid device is formed by bending a patterned steel plate, has an anti-skid effect, has a Z-shaped section, can effectively prevent feet from being gouged, and is provided with round holes at two ends for being connected with a T-shaped connecting piece as shown in figure 3.
T type connecting piece, its characterized in that: the steel plate is formed by vertically welding a side beam steel plate and a step steel plate, as shown in figure 4, the side beam steel plate is of a rectangular structure, the width of the side beam steel plate is the same as that of a bent side beam, four holes with the same interval with round holes in the bent side beam steel plate are formed in the side beam steel plate, the step steel plate is parallel to the step, and two round holes are reserved for connecting the step.
The flitch, its characterized in that: the steel plate and the lug plate are formed by a steel plate with the same width and two bending side beam gaps, a round hole is reserved in the steel plate and used for being connected with a wall body, the lug plate is located at the mounting position of the bending side beam, and the round hole is reserved in the lug plate and connected with the bending side beam.
Through the utility model discloses the process has designed a safe, practical assembled steel construction stair, can realize improving stair cyclic utilization, reduces the transportation and installs the target of tearing the degree of difficulty open.
The utility model discloses advantage and positive effect:
1. the utility model discloses steel construction stair realize the assembled target completely, all parts all adopt the method of mill's prefabrication, field installation, can reduce transportation space restriction by a wide margin, and no hoisting equipment also can artifically carry out ann and tear open, transportation work.
2. The utility model discloses reuse's target can be realized to the structure, and it marks time, flitch and T type connecting piece homoenergetic after the floor altitude variation continue to use, and the curb girder of bending can the secondary use equally through processing.
3. The utility model discloses the structure machining efficiency is high, the installation and the transportation degree of difficulty are big, are advanced assembled steel construction stair.

Detailed Description
Firstly, an expansion bolt is driven into a hole in the wall surface, the flitch plate 4 is installed on the wall surface, one end of each of two bent side beams 1 is connected to an ear plate of the flitch plate 4 through a bolt, the other end of each of the two bent side beams is placed on the horizontal ground, then the T-shaped connecting piece 3 is fixed on a reserved round hole in the inner side of each bent side beam through a bolt, the T-shaped connecting pieces 3 are required to be installed on the bent side beams 1 at two sides of each installation step 2, all the steps 2 are sequentially fixed on the T-shaped connecting pieces 3 through bolts after installation is completed, and the assembled steel structure stair is installed and can be put into use. If the field has hoisting equipment, the hoisting equipment can be integrally hoisted after ground assembly is finished; after the steel structure stair is used, all the components are sequentially detached, when other steel structure stairs with the same specification are machined, the steps 2 and the T-shaped connecting pieces 3 can be continuously used, the bent side beams 1 can be repeatedly utilized after being machined according to actual requirements, and recycling is achieved.
