Detailed Description

The following transverse direction is the left-right direction of fig. 1, i.e., the side direction of the installation duct and the side direction of the present bracket, and the following longitudinal direction is the axial direction of the duct, i.e., the left-right direction of fig. 2. The upper and lower parts are the upper and lower parts of the attached figures 1 and 2. The following lateral, longitudinal and vertical directions are for the sake of clarity of the structure of the present invention and are not intended to limit the present invention.

The structure of the anti-seismic support is shown in the attached figures 1 and 2, and comprises a screw rod 1, a reinforcing rib beam 2, a cross beam 5, a hinge joint 6, a transverse diagonal brace 8 and a longitudinal diagonal brace 10. The upper parts of the two lead screws 1 are fixedly connected to a building roof, the lower parts of the two lead screws are fixedly connected to the cross beam 5 by fasteners, a transverse diagonal brace 8 and two longitudinal diagonal braces 10 are fixedly connected to the connecting position of each lead screw 1 and the cross beam 5 in an inclined mode by hinges 6 and fasteners 7, the upper end of each transverse diagonal brace 8 or each longitudinal diagonal brace 10 is fixedly connected with an expansion bolt 9 by a hinge 6, and therefore the transverse diagonal braces 8 or the longitudinal diagonal braces 10 and the lead screws 1 form a stable triangular structure. Both ends of the transverse diagonal brace 8 or the longitudinal diagonal brace 10 are hinged 6, which is beneficial to adjusting the drilling position of the expansion bolt 9. I.e. the drilling position of the expansion bolt 9 can be adjusted within a certain range, not exclusively. This facilitates a quick mounting of the bracket.

In order to increase the stability of the screw rod 1, a reinforcing rib beam 2 is fixed on the screw rod 1 by a reinforcing rib bolt 3. The screw rod 1 is positioned in the middle of the reinforcing rib beam 2, and as shown in attached figures 3 and 4, the screw rod and the reinforcing rib beam are fixedly connected by a reinforcing rib bolt 3. The cross section structures of the reinforcing rib beam 2, the cross beam 5, the transverse diagonal brace 8 and the longitudinal diagonal brace 10 are the same and are square pipes with one side being through and long with openings, as shown in the attached figures 4 and 5. In order to place the lead screw in the reinforcing bar beam 2, a through-long opening is designed on one side of the reinforcing bar beam 2, and the two sides of the opening are designed into hook shapes to increase the strength and stability of the opening. Because the hook-shaped structure is similar to the reinforcing rib, the wall thickness of the square tube can be greatly reduced, and the overall weight of the anti-seismic support is further greatly reduced. Meanwhile, in order to further reduce the weight of the square tube, square holes are symmetrically processed on the other three side surfaces of the square tube.

The utility model utilizes the through long opening and the square hole and adopts the reinforcing rib bolt 3 to fixedly connect the screw rod 1 and the reinforcing rib beam 2. As shown in fig. 3 and 4, the reinforcing bar bolt 3 includes a bolt 31, a pressing plate 32, and a groove plate 33. The pressure plate 32 is connected with the bolt 31 in a threaded mode, the groove plate 33 is connected to the tail portion of the bolt 31 in a rotating mode through the screw 34 or the rivet, the screw 34 or the rivet is fixed in the center of the tail portion of the bolt 31, and the groove plate 33 can rotate around the screw 34 or the rivet. When fixing the screw rod 1, send into square intraduct with clamp plate 32 and frid 33 through opening and square hole, two curb plates contact the screw rod of frid 33, revolve wrong bolt 31 for clamp plate 32 moves to opening and square hole direction, tightly fixes clamp plate 32 at the internal surface of open-ended hook portion or square pipe, thereby realizes screw rod 1 and reinforcing bar roof beam 2 fixed connection. Two reinforcing rib bolts 3 are installed at the same position of the screw rod 1, so that the deformation of the screw rod 1 is avoided, the screw rod 1 is in four-point contact with the groove plate 33, and the stress balance of the screw rod 1 is ensured.

In order to prevent the deformation of the open square pipe when the fasteners 7 are fixedly connected, a buckle plate 4 is arranged at the joint of each fastener, the buckle plate 4 is of a groove shape, as shown in figure 5, and the size of the groove shape corresponds to the size of the outer surface of the square pipe. The pinch plate 4 is equivalent to the function of a gasket, provides a screwing plane for the fixed connection of the fastener 7, and can restrain the square tube and prevent the square tube from deforming under the action of external force. The wall thickness of the square pipe is reduced, and the weight of the anti-seismic support is reduced.
