Background technique

Stairs are an important connection channel between the upper and lower floors of a building. For multi-storey buildings without elevators, the connection between the upper and lower floors is only stairs. For high-rise buildings with elevators, stairs are also essential; slab concrete staircase structure Occupying a pivotal position in all buildings, it is a typical staircase form commonly used; for college students who have no practical experience and migrant workers who have not yet entered the working state, the slab concrete staircase structure has no actual engineering experience. The understanding of the slab concrete staircase structure is not enough. It is not easy for them to understand and master the structure and structure of the slab concrete staircase structure; the university teaching of construction engineering in China has always used the teaching method of lectures. Although secondary vocational education has made some breakthroughs in teaching, using multimedia and other information-based teaching methods, and setting up some teaching situations, it has not fundamentally got rid of the teaching mode that is mainly based on lectures; in order to make education keep up with the pace of China's economic development, the state It is decided to transform a number of applied technology universities. The teachers and facilities of these universities are set up according to the elite training mode. It is very difficult to get close to construction teaching; In recent years, the country has strengthened the training requirements for migrant workers, and strengthened the inspection and assessment of construction companies, but it is difficult for construction companies to organize training on the concrete structure of migrant workers. Universities of applied technology, vocational colleges, middle schools The current facilities of the vocational school cannot meet the training requirements of concrete structure construction for migrant workers engaged in the construction industry.

The slab concrete staircase structure model provided by the invention can solve these problems.

   The peripheral components of board-like concrete stair structure model includes body of wall (10) and floor plates (9), and the foundation of making is design Drawing, the standard width of a room in an old-style house of staircase design required, depth, by scaled mode, surround with the material of body of wall (10)；Will The floor height of floor, proportionally, carries out space separation with the material of floor plates (9), reserves mounting plate type concrete staircase knot The position of structure model；

   In board-like concrete stair structure model, the base plate of landing (7) is installed in the position of landing (7), is put down by stair The side of the base plate of platform (7) consolidates with body of wall (10)；In the opposite side that the base plate of landing (7) is corresponding with body of wall (10), peace Dress stair stringer shell (5)；The upper surface of the base plate of the suitable for reading and landing (7) of the outer panel of stair stringer shell (5) and neat and Intersect vertically；Same method installs the stair stringer shell (5) at lower two floors plate (9) place, and the method for installation is put down with stair The method of the stair stringer shell (5) near platform (7) is identical, simply require to note by the outer panel of stair stringer shell (5) respectively with Two floors plate (9) is connected, and the interior plate of reserved stair stringer shell (5) is connected with staircase boards (1)；

   Staircase boards (1) is set up after installing the outer panel of stair stringer shell (5), base plate, interior plate；Staircase boards (1) includes stair Base plate and check of staircase；Staircase boards (1) is angularly disposed；Upper surface that the base plate of the hypomere plate of staircase boards (1) is following and floor plates (9) the interior plate either flush of stair stringer shell (5) and connection；The upper surface of the base plate top of the hypomere plate of staircase boards (1) With the interior plate either flush of the stair stringer shell (5) near landing (7) and being connected；The end of the epimere plate of staircase boards (1) The interior plate either flush of the following upper surface of plate and the stair stringer shell (5) near landing (7) and being connected；Staircase boards (1) the interior plate either flush of the stair stringer shell (5) of the upper surface of the base plate top of epimere plate and floor plates (9) and company Connect；

   Landing reinforcing bar (8) is being installed, by principal rod, the frame of landing reinforcing bar (8) after checking staircase boards (1) installation qualification Stud, stirrup assemble after after spacer block is installed in the bottom of landing reinforcing bar (8) and both sides, entirety is placed on stair stringer shell (5), in, after passed examination, staircase boards reinforcing bar (2) is installed；

   After all reinforcement installation are good, landing (7) panel, stair step (3) are installed, make landing (7) panel and The side plate snapping of the side plate snapping of landing (7), stair step (3) and staircase boards (1)；

   All after parts installation qualification, Sign Board (11) is installed, makes the sensing bar of Sign Board (11) tie with board-like concrete staircase Each position of structure model connects.
