[0021] Example

[0022] An embodiment of the utility model is a detachable teaching aid for assembled building steel structures, comprising a teaching aid body, the teaching aid body comprising a base plate 10, two rows of H-shaped columns 12 are arranged above the base plate 10, the middle and top ends of the H-shaped columns 12 in the same row are respectively provided with main beams 13, the main beams 13 at the top ends of two mutually symmetrical H-shaped columns 12, a plurality of roof beams 14 are arranged above the main beams 13, a rigid support assembly 15 is arranged below the main beam 13 with the main beam 13 as a base point, a flexible support assembly 16 is arranged above the main beam 13, and a staircase assembly 2 for lifting activities is replaced above the base plate 10.

[0023] Reference Figure 1 and Figure 2 A pad 11 is provided between the bottom end of the H-shaped column 12 and the base plate 10. The pad 11 protects the base plate 10 to a certain extent, avoiding damage to the base plate 10 during assembly, thereby causing insufficient support force in the future. The main beam 13 is connected to the middle and top ends of the multiple H-shaped columns 12, dividing the entire door frame steel structure teaching aid into two layers, wherein a prefabricated floor assembly can be installed between the two main beams 13 to separate the first and second floors; a roof panel is provided on the top of the roof beam 14 to enclose the top.

[0024] The inter-column rigid support assembly 15 is mainly to ensure the overall stability and longitudinal rigidity of the teaching aid body skeleton, and to bear the longitudinal horizontal load of the wind from the teaching aid body, mainly the wind load. The inter-column support diagonal rods are divided into rigid support and flexible support according to whether they can effectively resist the axial pressure surface. The inter-column rigid support mainly adopts hot-rolled steel or steel pipe support components such as angle steel, channel steel, I-beam, etc., which are hinged to the column at both ends, and are usually connected by node plates. They are used in structures with high rigidity requirements such as multi-story frames and crane beam lower section supports. The intersection angle between the rigid support and the ground should be controlled between 30° and 60°. If the support is too steep, its lateral resistance efficiency will be greatly reduced.

[0025] The inter-column flexible support assembly 16 plays the same role as the rigid support assembly 15 and is mainly made of cross-shaped round tubes with tensioning devices (such as basket bolts). It must be tensioned during installation and is mainly used in door frame type steel frame structures.

[0026] The staircase assembly 2 provided at the same time can be used for lifting and lowering to adjust the height, so that the student's viewpoint can be changed, so as to observe the connection nodes at different viewing angles and heights, and learn and understand the teaching aid body more intuitively. In addition, the staircase assembly 2 can be assembled, which can satisfy the students' independent hands-on ability to a certain extent and deepen the learning of knowledge points.

[0027] In some preferred embodiments, a height-adjusting component 23 is fixedly provided above the base plate 10 , and both ends of the stair body 200 in the stair assembly 2 are detachably connected to the height-adjusting component 23 , respectively, and the height-adjusting component 23 drives the stair body 200 to rise or fall.

[0028] Specifically, Figure 3 and Figure 4 As shown, in the entire staircase teaching aid, by setting a height adjustment component 23 on the base plate 10, the height adjustment component 23 first adjusts the height of both ends of the staircase body 200, and then adjusts the height of one end of the staircase body 200 to meet the angle requirement according to the angle requirement to be displayed. The purpose of this is to enable students to observe the staircase body 200 more intuitively, so that they can stand in the adjusted staircase body 200 and observe the various connections inside the door frame steel structure from different perspectives, thereby improving the teaching effect.

[0029] In some preferred embodiments, the staircase body 200 includes a long frame 20, a platform 21 and a pedal 22 which are parallel to each other, the platform 21 is fixedly arranged at both ends of the long frame 20, a groove 201 is arranged inside the long frame 20, and the pedal 22 is clamped in the groove 201.

[0030] Specifically, Figure 4As shown, the staircase body 200 is mainly composed of a long frame 20 and a platform 21 which are parallel to each other. The two can be fixedly connected or detachably fixedly connected. Since a plurality of grooves 201 are arranged on the inner side of the long frame 20, the grooves 201 can make the pedal 22 clamped inside thereof without falling off. This structure allows students to disassemble independently and improves students' hands-on ability. When disassembling and assembling, students can disassemble and install according to their personal preferences, which also enhances the active atmosphere of the classroom. The pedal 22 is adapted to the specifications and sizes of the groove 201, so that the pedal 22 can be clamped more firmly inside the groove 201, and at the same time, the pedal 22 can be prevented from falling off when the pedal 22 is smaller than the groove 201.

[0031] In some preferred embodiments, the height adjustment assembly 23 includes a first electric push rod 230 and a second electric push rod 231, a through hole 211 is provided in the platform 21, and the staircase body 200 is connected to the first electric push rod 230 and the second electric push rod 231 respectively by setting screws 24 through the through hole 211. Specifically, Figure 3 and Figure 4 As shown, the entire staircase body 200 is mainly connected to the first electric push rod 230 and the second electric push rod 231 through the platforms 21 at both ends, and the height and angle are adjusted at the same time to ensure the firmness of the connection between the entire teaching aid body platform 21 and the height adjustment component 23. At the same time, the staircase body 200 and the height adjustment component 23 can be disassembled to more intuitively display the observation point. The screw 24 passes through the through hole 211 and is adapted to the threaded hole set in the first electric push rod 230 and the second electric push rod 231 to further enhance the students' hands-on ability.

Specifically, when adjusting the height and angle of the stair teaching aid, one of the controllers is selected for operation, for example, after opening the first controller 232 to select a suitable height, the first controller 232 is closed; then the second controller 233 is opened to adjust the height of the second electric push rod 231 according to the required display angle requirements. The height adjustment component 23 can be adjusted according to the specific angle requirements of the door frame steel structure.

[0033] In some preferred embodiments, a gasket 25 is further included, and the gasket 25 is located between the screw 24 and the platform 21. Specifically, Figure 4As shown, the screw 24 is adapted to the threaded holes (not shown in the figure) set in the first electric push rod 230 and the second electric push rod 231. The inner diameter of the through hole 211 in the platform 21 is greater than or equal to the outer diameter of the screw 24. By setting the gasket 25, the size of the through hole 211 of different platforms 21 can be met, which greatly improves the utilization rate of this stair body 200.
