Description

A prefabricated assembled staircase

technical field

The utility model relates to a staircase, in particular to a prefabricated assembled staircase, which belongs to the technical field of building structures.

Background technique

Stairs are one of the very important structural components in residential building structures. Generally, stairs are constructed of cast-in-place concrete. The cast-in-place staircase has a particularly large dead weight, and because of the poor versatility of the formwork, the cost is also high. In addition, if it is used in a cast-in-place structure, it is often unable to be hoisted due to the limitation of the lifting capacity of the tower crane. Concrete stairs generally adopt the method of pouring concrete after binding steel bars earlier simultaneously, and this method has complex construction technology, and the technical defect of long construction time.

For realizing the purpose of the utility model, the technical scheme that the utility model adopts is:

A prefabricated assembled staircase, comprising a prefabricated staircase main body and a platform, characterized in that: the bottom of both ends of the prefabricated staircase main body is provided with several bolts at a certain distance, and the platform is provided with sockets corresponding to the several bolts 1. The pin one is inserted into the first socket, and the prefabricated stair main body is respectively provided with a second socket and a third socket at a certain interval; a pedal is installed above the prefabricated staircase main body, and one end of the pedal is provided with a Socket 4, the other end is provided with oblique opening 1, and a support is provided in the middle of the pedal, and the support is inserted into the inside of socket 3; a support plate is also installed above the main body of the prefabricated staircase, and a horizontal, A vertical pin is arranged below, the horizontal pin is inserted into the inside of the socket four, the vertical pin is inserted into the inside of the socket two, and the bottom of the support plate is provided with the second oblique opening.

The angle of the bevel is the same as the installation inclination angle of the main body of the prefabricated staircase.

The two angles of the bevel are complementary to the installation inclination angle of the main body of the prefabricated staircase.

The bolt one, support, horizontal pin and vertical pin are all round steel with a diameter of 12mm.

The diameters of the first jack, the second jack, the third jack and the fourth jack are all 13 mm in diameter.

Compared with the prior art, the prefabricated assembled staircase of the utility model has the following advantages: 1. The required building materials are all prefabricated in the factory in advance, and can be directly assembled after being transported to the present, without further processing, reducing construction waste; 2. Each component is light in weight and can be assembled directly on site without the help of lifting equipment. It can be quickly installed and the construction period is greatly shortened; 3. The structure is simple, and the disassembly and assembly aspects reduce the technical quality requirements for workers.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

A prefabricated assembled staircase, comprising a prefabricated staircase main body 6 and a platform 7, the bottom of both ends of the prefabricated staircase main body 6 is provided with several bolts 11 at a certain distance, and the platform 7 is provided with a plurality of bolts 11 corresponding to Jack one 12, said latch one 11 is inserted in the inside of jack one 12 and prefabricated stair main body 6 is fixedly installed between two floors; Said prefabricated staircase main body 6 is also provided with jack two 9 and Jack three 10; pedal 4 is installed above the prefabricated stair main body 6, one end of said pedal 4 is provided with jack four 8, the other end is provided with oblique opening one 13, said pedal 4 is provided with support 2 in the middle, said pedal 4 Support 2 inserts jack 3 10 interiors and supports pedal 4 so that people will not be damaged when going up and down the stairs above; a support plate 5 is also installed above the prefabricated staircase main body 6, and a horizontal pin 3, The bottom is provided with a vertical pin 1, and the horizontal pin 3 is inserted into the inside of the jack 4 8 to fix and lock the pedal 4 to prevent it from shaking and unstable. The vertical pin 1 is inserted into the inside of the jack 2 9 to fix the support plate 5, thus forming a staircase. structure, the bottom of the support plate 5 is provided with a bevel 2 14.

In order to install no gap between the pedal 4 and the prefabricated staircase main body 6, the oblique opening 13 angle is the same as the installation inclination angle of the prefabricated staircase main body 6; also for the installation between the support plate 5 and the prefabricated staircase main body 6 there is no gap, the oblique opening 2 14 angle The installation inclination angle of the prefabricated stair body 6 is complementary; the first pin 11, the support 2, the horizontal pin 3 and the vertical pin 1 are all round steel with a diameter of 12mm, so that the specifications and models are unified, which is convenient for production and processing; the first jack 12, the second jack 9.
