[0028] In some preferred embodiments, a plurality of symmetrical short columns 101 are provided above the cushion layer 100, and the prefabricated column assembly 10 is assembled above the short columns 101 by anchor bolts 110. The prefabricated column assembly 10 includes a round steel tube 102, an H-shaped column 104, a cross column 103, and a square tube column 105. Two round steel tubes 102 or two H-shaped columns 104 or two cross columns 103 or two square tube columns 105 are symmetrical to each other along the center of the short side of the cushion layer 100.

[0029] Specifically, Figure 4 As shown, a short column 101 is set above the cushion layer 100 and fixed with anchor bolts 110. The purpose of the cushion layer 100 is to improve the working conditions of the base and the soil foundation through water isolation, drainage and antifreeze. The water stability of the cushion layer 100 is required to be good. The length of the cushion layer 100 is 15000mm, the width is 5400mm, and the thickness is 150mm.

[0033] The inter-column rigid support assembly 3 is mainly set to ensure the overall stability and longitudinal rigidity of the teaching model skeleton and to bear the longitudinal horizontal load on the top. The inter-column rigid support mainly uses hot-rolled steel or steel pipe support components such as angle steel, channel steel, I-beam, etc., which are connected to the columns at both ends. They are usually connected by node plates and 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.

[0034] In some preferred embodiments, the top of the prefabricated column assembly 10 is provided with a plurality of transversely and longitudinally assembled main beams 120, a secondary beam 130 is assembled between two transversely assembled main beams 120, a composite floor 280 is assembled above the main beams 120 and the secondary beams 130, the two-story structure 2 is located above the composite floor 280, and an H-shaped column 290 is arranged above the composite floor 280, and the H-shaped column 290 is coaxial with the prefabricated column assembly 10 of the first-story structure 1.

[0035] Specifically, Figure 3 As shown, the main beam 120 is arranged in two directions, the main beam 120 between two steel structures of the same type is longitudinal, and the main beam 120 between two steel structures of different types is transverse. The main beam 120 mainly bears and transfers the load, and the number of the main beams 120 is eight. The secondary beam 130 is located between the two transverse main beams 120, and also plays the role of transferring the load. The number of the secondary beams 130 is three. The composite floor slab 280 is a corrugated steel plate composite floor slab 280, which is formed by pressing galvanized thin steel plates, and its cross section is a trapezoidal, inverted trapezoidal or similar shaped waveform. It is used for permanent support formwork of floor slabs in buildings, and can also be selected as steel plates for other purposes. It can be divided into open floor slabs, fully closed floor slabs, and dovetail floor slabs.

[0036] The thickness of the floor decking profile is 0.8mm, 1.0mm, 1.2mm, the width is 688mm-940mm, and the height is 51mm-76mm. The floor decking of the engineering floor works together with the reinforced concrete structure, which is a composite structure. The floor decking is laid and connected with the steel beam, the plate end and the steel beam are spot welded through, and the bolts and steel beams are penetrated and welded in the middle; the floor decking is connected by bite-pressure holes with special clamps; the plug is spot welded with a special galvanized plug plate and the floor decking and steel beam.

[0037] In some preferred embodiments, roof beams 200 are provided at the top ends of the H-shaped columns distributed longitudinally in the two-story structure 2 , and cantilever beams 210 are provided at both ends of the roof beams 200 .

[0038] Specifically, the roof beam 200 is arranged at the top of a plurality of H-shaped columns 290 to form the main roof frame structure at the top of the two-story structure 2. The roof beam 200 is the main structural member that bears the pressure from the purlin 260 and the roof panel in the roof structure, and mainly bears bending moment and shear force. The cantilever beam 210 is located at the two ends of the roof beam 200, one end of which is a fixed support, and the end away from the roof beam 200 is a free end.

[0039] In some preferred embodiments, a plurality of thin rod supports 220 are arranged between adjacent H-shaped columns 290, and a horizontal support rod 230 is arranged between two thin rod supports 220, and both ends of the horizontal support rod 230 are respectively connected to the H-shaped column 290. The thin rod supports 220 form a stable longitudinal frame between the roof beams 200 to ensure the longitudinal rigidity of the steel structure. The thin rod supports 220 are arranged along the entire length of the house, connecting the ridge nodes and the support nodes, and play a role in connecting each roof truss. The horizontal support rod 230 is generally composed of a cross rod and a rigid tie rod. The cross rod used in this teaching model is a round rod with a tensioning device for easy tightening. The horizontal support rod 230 forms a complete structural system by connecting the various parts of the steel structure, thereby improving the overall rigidity and strength of the structure.

[0040] In some preferred embodiments, a plurality of purlins 260 are provided at the top of the roof beam 200 . The purlins 260 are perpendicular to the roof beam 200 . Struts 240 and diagonal braces 250 are provided between adjacent purlins 260 . A color steel roof 90 is constructed at the top of the purlins 260 .

[0041] Specifically, the purlin 260 is a horizontal member distributed along the length of the roof, which mainly plays a supporting role. It is placed in the plane of the roof truss to reduce the span of the roof panel. The horizontal spacing between adjacent purlins 260 is 1100mm. The support rod 240 is used to prevent the flexural deformation of the purlin 260, and the diagonal brace 250 is used to strengthen the lateral rigidity of the steel structure. A tie rod is also provided between adjacent purlins 260. The support rod 240, the purlin 260 and the diagonal brace 250 form a geometrically invariant system, which plays a supporting role in the weak axis direction of the purlin 260 to prevent the purlin 260 from deforming in the weak axis direction, which is dangerous.

[0042] In some preferred embodiments, corner braces 270 are provided on both sides of the roof beam 200, and one end of the corner brace 270 away from the roof beam 200 is fixedly connected to the purlin 260, and the angle between the corner brace 270 and the roof beam 200 or the purlin 260 is greater than or equal to 35°.

[0043] Specifically, refer to Figure 5 The corner brace 270 can make the structure have better energy dissipation performance and deformation capacity, thereby protecting the main components of the structure. The corner brace 270 is generally made of angle steel, and the angle between the corner brace 270 and the purlin 260 or the wall beam is greater than or equal to 35°. The two ends of the corner brace 270 are connected to the beam or side column and the purlin 260 or the beam with bolts to improve the stability of the teaching model.

[0044] In addition, the roof beam 200 is made of I-beam, which is generally placed horizontally to support the board and bear various vertical loads transmitted from the board and the deadweight of the beam. At the same time, when installing the bolts, a second gasket 291 is set, which forms a fixed connection between the beam and the purlin 260, and a fixed connection between the corner brace 270 and the beam.

[0045] In some preferred embodiments, in the two-story structure 2, an inter-column flexible support assembly 6 is provided between adjacent H-shaped columns 290, and the periphery of the first-story structure 1 and the second-story structure 2 is provided with a corrugated steel plate wall panel 5, and the interior is provided with a lightweight interior wall partition panel 4, and the corrugated steel plate wall panel 5 is provided with a door and window assembly 9.

[0046] Specifically, the flexible support between columns is mainly to ensure the overall stability and longitudinal rigidity of the teaching model frame and bear the longitudinal horizontal load. The diagonal support rods between columns are divided into rigid support and flexible support according to whether they can effectively resist the axial pressure surface. The flexible support is made of cross-shaped round tubes with tensioning devices, which must be tensioned during installation and are mainly used in portal steel frame structures.

[0047] Corrugated steel wall panel 5 refers to a building maintenance panel made of color coated steel sheet or galvanized steel sheet as raw material, which is formed by roller cold bending. When used for building roofs or walls, its thickness should not be less than 0.4mm.

[0048] The corrugated steel wall panel 5 is divided into two types: non-insulated single-layer corrugated steel panel and thermal insulation composite corrugated steel panel. The non-insulated single-layer corrugated steel panel currently used more is the color-coated galvanized steel panel. It is generally a corrugated plate with a thickness of 0.4 to 1.6 mm. The color-coated galvanized steel panel has high heat resistance and corrosion resistance, and its general service life can reach about 20 years; the thermal insulation composite corrugated steel panel can be filled with plate-shaped insulation materials such as polystyrene foam board in the inner and outer layers of steel plates during construction. The structure of the corrugated steel plate exterior wall strives to be simple, easy to construct, and reliably connected to the wall beam. The detailed structures such as corners should have sufficient overlap length to ensure the waterproof effect. The door and window components 9 are mainly arranged in the external corrugated steel wall panel 5.

[0049] Lightweight interior partition wall is a new type of energy-saving wall material. It is a wall material that looks like a hollow floor slab, with male and female grooves on both sides. When installing, you only need to stand up the board, apply a small amount of caulking mortar on the male and female parts, and then assemble them. It is composed of harmless phosphogypsum, lightweight steel slag, fly ash and other industrial waste residues, and is cured by variable frequency steam pressure. Lightweight interior partition board has the advantages of light weight, high strength, multiple environmental protection, thermal insulation, sound insulation, breathable humidity control, fire prevention, fast construction, and reduced wall cost. The inner layer is equipped with reasonably arranged heat-insulating and sound-absorbing inorganic foam profiles or other thermal insulation materials.
