[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0022] Reference Figure 1-7 As shown, a novel beam-column connection structure includes a beam 1 and a column 2. A first mating member 3 is provided at the longitudinal end of the beam 1, and a fixing plate 4 and a second mating member 5 are provided at the longitudinal end of the column 2. The first mating member 3 is placed inside the column 2. Moving the second mating member 5 inside the column 2 to bring it closer to the fixing plate 4 causes the first mating member 3 to come into contact with the second mating member 5, thereby causing the beam 1 to generate a force in the direction of the column 2. The proximity distance between the first mating member 3 and the second mating member 5 is proportional to the contact force.

[0023] First of all, it should be noted that both the beam 1 and the column 2 are hollow tubular. Specifically, the first fitting 3 is located at the opening inside the tube of the beam 1, and the second fitting 5 is located at the opening inside the tube of the column 2.

[0024] The first mating component 3 includes a connecting plate 31 fixed to the pipe opening of the beam 1. The connecting plate 31 is groove-shaped and has folded edges on all four sides. It should be noted that the fixing method of the connecting plate 31 to the first mating component 3 is not singular. It can be by welding or by connecting with screws to fix the four folded edges to the beam 1. A locking hole is provided at the center of the connecting plate 31. The first mating component 3 also includes a hook 32. The hook 32 includes a connecting end and a hook 32 end. The connecting end is inserted into the locking hole. The hook 32 is fixed to the connecting plate 31 by welding. The connecting plate 31 is flush with the pipe opening plane of the beam 1, and the hook 32 protrudes from the pipe opening plane of the beam 1.

[0025] In order to ensure that the hook 32 can be inserted into the column 2, an insertion hole 21 is provided on the side of the end of the column 2, and the hole surface of the insertion hole 21 matches the hook 32 end of the hook 32.

[0026] Specifically, the fixing plate 4 is fixed at the opening of the column 2 in a state parallel to the end face of the column 2. In order not to affect the hook 32 entering the column 2, the position of the fixing plate 4 inside the column 2 will not interfere with the card hole. Therefore, the fixing plate 4 can be installed at the upper or lower part of the card hole. Preferably, the fixing plate 4 is installed at the lower part of the card hole, and the upper surface of the fixing plate 4 is flush with the bottom edge of the card hole. This arrangement can further ensure that when the hook 32 enters the card hole, the bottom surface of the hook 32 protruding from the connecting plate 31 is attached to the upper surface of the fixing plate 4, and the fixing plate 4 can support the hook 32.

[0027] The hook head of the hook 32 faces the opening of the column 2. A first inclined surface 321 is provided on the inner side of the hook head of the hook 32. The first inclined surface 321 forms a gap with the inner wall of the column 2 opposite to the inner side of the hook 32. Specifically, the upper end of the first inclined surface 321 to the inner wall of the column 2 is the first gap 3211, and the lower end of the first inclined surface 321 to the inner wall of the column 2 is the second gap 3212. The first gap 3211 is greater than the second gap 3212.

[0028] The second mating component 5 includes an integral mating plate 51 and a locking block 52 disposed on the mating plate 51. The mating plate 51 is rectangular in shape and matches the pipe opening interface of the column 2. The four corners of the mating plate 51 are chamfered. Usually, only one adjacent side needs to be provided with the locking block 52. However, in order to ensure that the locking block 52 can engage with the hook 32 no matter how the second mating component 5 is placed, it is preferable that four locking blocks 52 are provided and disposed at the middle of the four sides of the mating plate 51. The assembly 5 is installed into the column 2 in an upside-down manner (the locking block 52 faces downward, with the mating plate 51 above and the locking block 52 below). A second inclined surface 521 is provided on the inner side of the locking block 52. Similarly, the second inclined surface 521 forms a gap with the inner wall of the column 2. The upper end of the second inclined surface 521 to the opposite inner wall of the column 2 is the third gap 5211, and the lower end of the second inclined surface 521 to the opposite inner wall of the column 2 is the fourth gap 5212. The third gap 5211 is greater than the fourth gap 5212.

[0029] It should also be specifically noted that the fourth spacing 5212 is greater than the second spacing 3212 and less than the first spacing 3211, the third spacing is greater than the first spacing 3211, and the first mating component 3 moves within the column 2 toward the side of the fixing plate 4 so that the first inclined surface 321 fits against the second inclined surface 521.

[0030] Furthermore, in order to ensure that the second mating component 5 can be fixed within the column 2, and at the same time, that the beam 1 has a clamping force towards the column 2, a first through hole 511 is provided at the center of the second mating component 5, specifically at the center of the mating plate 51, and a second through hole 41 is provided at the center of the fixing plate 4. A fastening screw 6 is provided to enter through the first through hole 511 and screw into the second through hole 41 on the fixing plate 4. Specifically, the first through hole 511 is a axial hole, and the second through hole 41 is a threaded hole. The lower part of the fastening screw 6 is a threaded part, and the upper part is an axial part. The threaded part passes through the first through hole 511 and is screwed into the second through hole 41. By rotating the fastening screw 6, the second mating component 5 moves towards the fixing plate 4.

[0031] The working process of this utility model is as follows: First, the hook 32 can be pre-installed by welding to the connecting plate 31. The connecting plate 31 is then welded to the pipe opening of the beam 1. The fixing plate 4 is welded into the column 2. These pre-installation operations reduce the user's installation steps. When the user is installing, the end of the hook 32 at the end of the beam 1 is inserted into the insertion hole 21, while ensuring that the hook 32 is supported on the fixing plate 4. Then, the second mating part 5 is inserted from top to bottom. The second inclined surface 521 on the locking block 52 of the column 2 contacts the first inclined surface 321 on the hook 32. The second mating part 5 is pre-placed inside the column 2. Then, the fastening screw 6 is inserted into the first through hole 511. The thread at the lower part of the fastening screw 6 is screwed into the second through hole 41. By rotating the fastening screw 6, the second mating part 5 moves downward. The first inclined surface 321 and the second inclined surface 521 cooperate to exert a clamping force on the hook 32 and drive the beam 1 towards the column 2.
