[0035] In order to further understand the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Combination Figure 1 , Figure 2 , Figure 4 and Figure 6 ,as well as Figures 7 to 9The utility model provides a T-beam steel bar assembly entity teaching model, including a T-beam body 1 and a general frame 2, and a base 3 is installed under the general frame 2;

[0037] A fitting edge 12 is provided at one corner of the upper part of the T-beam body 1, a positioning block 13 is also provided on one side of the T-beam body 1, and a plurality of through holes 11 penetrating through the body of the T-beam body 1 are provided at one end thereof;

[0038] The main frame 2 is composed of a plurality of groups of vertical beam frames 21 and inner frames 24 which are adjacent to each other and parallel to each other. A card frame 241 which is assembled with the fitting edge 12 on the T-beam body 1 is provided on one side of the surface of the inner frame 24. The vertical beam frames 21 are used to prevent the T-beam body 1 from linearly displacing forward and backward along its length direction. The surfaces of the vertical beam frames 21 at both ends are equipped with end frames 23 of the same shape as the T-beam body 1. The inner sides of the end frames 23 are provided with plug posts 232 of the same number as the through holes 11. The plug posts 232 are used to prevent the T-beam body 1 from linearly displacing up and down along the extended height direction, and to provide fixed support for the T-beam body 1.

[0039] The vertical beam frame includes two groups of splicing strips 211 and fixing plates 26. One group of splicing strips 211 is provided with slots 2111, and the other group of splicing strips 211 is provided with inserts that fit into the slots 2111. The surface of the fixing plate 26 is provided with a hexagonal sleeve 261.

[0040] A raised surface is provided in the middle of the base 3, and second side bars 33 are fixed on both sides of the raised surface. The second side bars are used to prevent the T-beam body 1 from linearly displacing left and right in the extended width direction. The surface of the base 3 is also provided with a plurality of positioning points 31 and positioning rods 32 for determining the position of the vertical beam frame;

[0041] In this embodiment, the assembly steps of the T-beam reinforcement assembly physical teaching model are as follows:

[0042] Step 1: First, place the inner frame 24 on the middle section of the surface of the base 3, and use the fixing plate 26, the latch, and the second side strip to fix the inner frame 24 and the T-beam body 1 in the first step;

[0043] Step 2: Multiple groups of splicing strips 211 are spliced ​​in pairs to form multiple groups of vertical beams. During the splicing process, the insert strips on one splicing strip 211 need to be aligned with the slots 2111 on another splicing strip 211 so that the two can be combined. The vertical beams formed by the combination of the two are fixed by the positioning rods 32 on the surface of the base 3, thereby forming the general shape of the overall frame 2, and completing the second step of fixing the inner frame 24 and the T-beam body 1;

[0044] Step 3: Finally, insert the plug column 232 on one side of the end frame 23 into the through hole 11 at the end of the T-beam body 1 to complete the final fixation of the T-beam body 1;

[0045] In the process of splicing and assembling the T-beam steel bar model, construction workers can intuitively and in real time understand the connection position and quantity requirements between each structure, so that they can quickly understand the specific structure of the T-beam steel bar, improve learning efficiency, and then improve construction quality in the actual construction process;

[0046] It should be noted that the teaching model is proportionally reduced from the actual T-beam steel bars, with the longest length not exceeding one meter. It is made of elastic plastic, which ensures the stability of its own strength while being lightweight, so it can be disassembled and assembled many times and has a long service life.

[0047] Combination Figure 7 , Figure 8 and Fig.10 A plurality of cross beams 212 are assembled on one side of the vertical beam frame, a clamping strip 2121 is arranged at one end of the cross beam 212, the clamping strip 2121 matches with the bayonet 2112, a clamping block 2122 is arranged at one end of the clamping strip 2121, and the vertical beam frame and the cross beam 212 can be fixed by the mutual limitation among the clamping strip 2121, the clamping block 2122 and the bayonet 2112. During this operation, step one in the assembly steps of the above-mentioned T-beam steel bar assembly entity teaching model can be supplemented. A support beam 213 is also fixedly arranged at the other end of the cross beam 212.

[0048] Combination Figure 5 and Fig.10 , first side bar frames 245 are fixedly arranged on both sides of the inner frame 24. When the inner frame 24 is placed on the middle surface of the base 3, the first side bar frame 245 is flush with the second side bar frame 33. Multiple sets of fixing members 243 are arranged on both sides of the inner frame 24. The fixing members 243 are composed of a fixing plate 26 and a latch, which are used to connect the first side bar frame 245 and the second side bar frame 33, so as to complete the fixing of the inner frame 24. During the fixing process, the latch is inserted into the hexagonal sleeve 261 on the surface of the fixing plate 26. The inside of the hexagonal sleeve 261 and the surface of the latch are both rough, which can effectively increase the friction between the two and enhance the connection relationship between the first side bar frame 245 and the second side bar frame 33. The hexagonal shape of the surface of the hexagonal sleeve 261 can increase the friction between the human hand, which is convenient for operators to disassemble and assemble it;

[0049] The inner frame 24 is also provided with load-bearing strips 244 on both sides, and the load-bearing strips 244 are plugged with the support beam 213. This operation can be used to supplement the step 2 in the assembly steps of the T-beam steel bar assembly entity teaching model. The lower end of the load-bearing strip 244 is in contact with the top surface of the first side strip frame 245. The three can effectively disperse the pressure applied to the surface of the T-beam body 1. The inner frame 24 is provided with a placement table 246 for supporting the T-beam body 1. The placement table 246 is a hollow structure to reduce its own weight. Thin edges are provided on both sides of the placement table 246 for plugging with the long strips 247 on the inner side of the baffles on both sides to form the inner frame 24 as a whole;

[0050] Combination Figure 3 and Figure 4 , the two ends of the T-beam body 1 are also provided with limit strips 14, which are used to contact the protruding surface of the upper end of the end frame 23, further improving the stability of the T-beam body 1, and causing the T-beam body 1 to be displaced after being subjected to force during the process of splicing and assembling the T-beam steel bar model. This process can supplement step three in the assembly steps of the above-mentioned T-beam steel bar assembly physical teaching model;

[0051] Combination Figure 3 and Figure 4 , reinforcing ribs 15 are also provided on both sides of the T-beam body 1, and a receiving groove 242 is formed on the inner side of the inner frame 24, and the reinforcing ribs 15 can be located inside the receiving groove 242. Through the mutual restriction between the receiving groove 242 and the reinforcing ribs 15, the stability of the T-beam body 1 inside the inner frame 24 is further enhanced;

[0052] Combination Figure 4 A side bracket 22 is inserted into the outside of each group of vertical beams, and a mesh platform 221 is placed above the side bracket 22 to simulate the working platform on the actual T-beam steel bars. Multiple groups of vertical poles 222 are also fixed to the outside of the mesh platform 221. The multiple groups of vertical poles 222 are connected by multiple groups of first connecting strips 223. The first connecting strips 223 can be regarded as guardrails in the actual construction process.

[0053] Combination Figure 4 A ladder 231 is provided on one side of the end frame 23, which can be regarded as an auxiliary tool for construction workers to climb the top of the T-beam reinforcement during actual construction.

[0054] Combination Figure 6 and Fig. 9 Each group of relatively positioned vertical beam members is provided with a second connecting bar 25, and the second connecting bar 25 is fixed to the vertical beam frame through a fixing plate 26, so as to increase the overall structural strength of the total frame 2 and ensure the stability of the T-beam body 1.
