DETAILED DESCRIPTION

[0022] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Reference Figure 1-Figure 4 A connection structure suitable for beams and columns of low-rise steel structures includes a vertical beam body 2 and a horizontal beam body 4. The vertical beam body 2 and the horizontal beam body 4 have the same internal structure. A reinforcement mechanism is arranged on one side of the vertical beam body 2. The reinforcement mechanism includes a support member 3, a limit member 5 and a connecting plate 11. A plug-in groove 17 is engaged on one side of the support member 3. The plug-in groove 17 is arranged on one side of the horizontal beam body 4. A guide groove 9 is arranged on one side of the horizontal beam body 4. The guide groove 9 is slidably connected to the limit member 5. One side of the limit member 5 is inserted into the support member 3. One side of the support member 3 is overlapped with the horizontal beam body 4. One side of the horizontal beam body 4 is fixedly connected to the connecting plate 11. The connecting plate 11 is internally penetrated. A plug-in rod 10 is inserted, one end of the plug-in rod 10 is fixedly connected to the vertical beam body 2, an extension rod 8 is inserted at one side of the horizontal beam body 4, one end of the extension rod 8 is fixedly connected to the built-in plate 7, one side of the built-in plate 7 is fixedly connected to the inner wall of the horizontal beam body 4, one side of the connecting plate 11 is fixedly connected to a fixing plate 14, the inner wall of the fixing plate 14 is slidingly connected to the vertical beam body 2, a positioning rod 13 is inserted at one side of the fixing plate 14, one end of the positioning rod 13 is fixedly connected to a positioning block 12, one side of the positioning block 12 is fixedly connected to the vertical beam body 2, a locking block 6 is engaged at one side of the support member 3, the locking block 6 is an inverted L-shape, and one end of the locking block 6 is locked and connected to the horizontal beam body 4.

[0024] Specifically, the plug-in groove 17 can guide the installation of the support member 3, which is convenient for connecting the auxiliary support member 3 with the vertical beam body 2. After one end of the support member 3 is installed, the other end is overlapped with the cross beam body 4. At this time, the locking block 6 is respectively engaged with the cross beam body 4 and the support member 3 to achieve the positioning of the support member 3. At this time, the initial position of the support member 3 can be defined, and then the limit member 5 is slid along the guide groove 9 so that the end of the limit member 5 passes through the support member 3. At this time, the limit member 5 is engaged with the inner wall of the guide groove 9 to shorten the position of the support member 3 and avoid the support during the use of the beam column. When the parts 3 fall down, the support parts 3 are connected with the upper and lower sides of the cross beam body 4 by means of the support parts 3, and a stable triangular structure is formed between the vertical beam body 2 and the cross beam body 4, so as to support and reinforce the connection between the vertical beam body 2 and the cross beam body 4, improve the stability of the connection between the vertical beam body 2 and the cross beam body 4, and resist the shear force applied to the beam column when in use. The connecting plate 11 and the fixing plate 14 can be formed into an L shape, and the fitting effect with the outer wall of the vertical beam body 2 is good. The positioning rod 13 and the fixing plate 14 are connected to guide the installation of the cross beam body 4, so as to facilitate the subsequent installation and disassembly of the cross beam body 4.

[0025] As an optimization solution, Figure 3 and Figure 4 As shown, the inner walls of the vertical beam body 2 and the horizontal beam body 4 are fixedly connected with a baffle 1, one side of the baffle 1 is fixedly connected with a connecting strip 2 16, one side of the connecting strip 2 16 is fixedly connected to the built-in plate 7, one side of the built-in plate 7 is fixedly connected with a connecting strip 15, and one side of the connecting strip 15 is fixedly connected to the inner wall of the vertical beam body 2.

[0026] Specifically, the baffle 1 can be used to seal one side of the inner cavity of the vertical beam body 2 and the cross beam body 4, thereby protecting the internal structure of the vertical beam body 2 and the cross beam body 4 and reducing damage to the internal structure. The connecting strip 15 and the connecting strip 2 16 can respectively connect the two sides of the built-in plate 7, thereby supporting and reinforcing the two sides of the built-in plate 7, improving the internal strength of the vertical beam body 2 and the cross beam body 4, and reducing the deformation of the vertical beam body 2 and the cross beam body 4.

[0027] Working principle: First, the right angle formed by the connecting plate 11 and the fixing plate 14 is clamped on one side of the vertical beam body 2. At this time, the positioning rod 13 is inserted into the fixing plate 14, the plug-in rod 10 passes through the connecting plate 11, and one end of the extension rod 8 is inserted into the side wall of the vertical beam body 2 to achieve the preliminary connection between the vertical beam body 2 and the cross beam body 4. Then, the end of the support member 3 away from the cross beam body 4 is inserted into the plug-in groove 17, and the other end is clamped and fixed by the clamping block 6. Then, the limiting member 5 is moved along the vertical beam body 2, so that the limiting member 5 passes through the supporting member 3, and the supporting member 3 is fixed to the position, and the connection between the vertical beam body 2 and the cross beam body 4 is completed.

[0028] The vertical beam body 2 and the horizontal beam body 4 have the same internal structure. The built-in plate 7 can be used to connect the diagonals inside the vertical beam body 2 or the horizontal beam body 4 to achieve stable support for the inside of the vertical beam body 2 or the horizontal beam body 4. The two sides of the built-in plate 7 are respectively connected with a connecting strip 15 and a connecting strip 2 16. The baffle 1 and the built-in plate 7 are connected by connecting strip 2 16. The cavity inside the vertical beam body 2 or the horizontal beam body 4 can be divided into multiple triangles, thereby improving the supporting strength inside the vertical beam body 2 and the horizontal beam body 4 and reducing the deformation of the vertical beam body 2 or the horizontal beam body 4 caused by external forces when in use.
