[0018] like Figure 1 and Figure 2 As shown, a steel beam connection structure includes a vertical plate 1, a baffle plate 2 and a limit support mechanism 3. The baffle plate 2 is arranged at the upper and lower ends of the vertical plate 1. The baffle plate 2 extends to one side of the vertical plate 1 along the vertical direction of the vertical plate 1. The limit support mechanism 3 is arranged on the side wall of the vertical plate 1. The limit support mechanism 3 is located on one side of the extension direction of the baffle plate 2. The limit support mechanism 3 is symmetrically arranged up and down, and is used for limiting the end face of the steel beam and supporting the inner wall. The end face of the steel beam is fixed by limiting the symmetrical baffle plate 2.
[0019] like Figure 1-3As shown, in order to increase the support and limit of the end face of the steel beam, the limit support mechanism 3 includes a connecting block 4, a support rod 5 and a slider 6. One end of the connecting block 4 is fixedly connected to the side wall of the vertical plate 1. The connecting blocks 4 are symmetrically arranged in pairs. One end of the support rod 5 passes through the connecting block 4 and is hinged to the end of the connecting block 4 away from the vertical plate 1. The slider 6 passes through the left-right symmetrical support rod 5 and is slidably arranged on the outside of the support rod 5. A limit groove 9 is opened in the middle of the outer wall of the slider 6. The limit groove 9 is arranged in an annular shape. A support spring 7 is wound around the outer wall of the support rod 5. The support spring 7 is located between the slider 6 and the connecting block 4, a pressing roller 8 is rotatably arranged at one end of the support rod 5 away from the connecting block 4. When the end face of the steel beam is inserted between the symmetrical baffles 2, the upper and lower outer walls are in contact with the inner walls of the symmetrical baffles 2. At the same time, the end face of the vertical plate in the middle of the steel beam is stuck in the limiting groove 9, pushing the slider 6 to slide along the axial direction of the support rod 5. The angle of the upper and lower symmetrical support rods 5 increases. Under the reverse support of the support spring 7, the slider 6 is in close contact with the end face of the steel beam. At the same time, the pressing rollers 8 on the upper and lower sides are respectively supported between the inner upper wall and the inner bottom wall of the steel beam, so as to limit the end face and the upper and lower side walls of the steel beam.
[0020] In order to prevent the steel beam from separating from the device, a positioning plate 10 is provided on the outer wall of the slider 6 near the limit groove 9. The positioning plates 10 are located on both sides of the limit groove 9 and are symmetrically arranged on the left and right. The side of the positioning plate 10 away from the slider 6 is threadedly connected with a limit screw 11. The limit screw 11 connected to the positioning plate 10 is rotated so that the limit screw 11 clamps both sides of the vertical plate in the middle of the steel beam, and the fixing effect with the punched steel beam is best.
[0021] Among them, reinforcing ribs 12 are provided between the side walls of the connecting block 4 and the side walls of the vertical plate 1 to increase the supporting strength of the connecting block 4 and avoid disconnection at the connection. Fixing holes 13 are opened on both sides of the upper part of the baffle 2. The fixing holes 13 are symmetrically arranged in pairs with the vertical plate 1 as the center. The fixing holes 13 are used to bolt the device or connect the steel beam in the vertical direction.
[0022] In specific use, when installing the building frame, the operator first installs the longitudinal steel beam through the fixing holes 13 on the upper and lower baffles 2. After the device is fixed, the end face of the transverse steel beam is inserted between the symmetrical baffles 2, and the upper and lower outer walls are in contact with the inner walls of the symmetrical baffles 2. At the same time, the middle vertical plate end face of the steel beam is stuck in the limit groove 9, pushing the slider 6 to slide along the axial direction of the support rod 5, and the angle of the upper and lower symmetrical support rods 5 increases. Under the reverse support of the support spring 7, the slider 6 is in close contact with the end face of the steel beam, and at the same time, the pressing rollers 8 on the upper and lower sides are respectively supported between the inner upper wall and the inner bottom wall of the steel beam;
[0023] In order to increase the connection stability of the steel beam and avoid separation of the steel beam from the device, holes can be punched in the vertical plates at both ends of the steel beam in advance. When the symmetrical positioning plates 10 are located on both sides of the vertical plates in the middle of the steel beam, the limit screws 11 connected to the positioning plates 10 are rotated so that the limit screws 11 clamp the two sides of the vertical plates in the middle of the steel beam and pass through the through holes to realize the positioning, connection and installation of the steel beam.
