Technical Field

[0001] The utility model relates to a bracket, in particular to a bracket for steel structure engineering. Background Technique

[0002] A steel structure is a structure composed of steel materials. The structure is mainly composed of beam steels, steel columns, steel frames, etc. made of shaped nails and steel plates. Welds, bolts or rivets are usually used to connect between the components or parts. During the actual use of steel structure components, due to changes in use conditions, wear during use, or the structural or local bearing capacity not meeting the design requirements caused by construction designers, etc., it is necessary to reinforce and support them with brackets.

[0003] After retrieval, a patent with the patent application number 202122367205.1 discloses a steel structure bracket, including grounding rods. The number of the grounding rods is two. Crossbars are arranged above both of the two grounding rods. Two lower hinge rods are hinged on the side surfaces of the two grounding rods close to each other. Rotating blocks are hinged at the upper ends of the four lower hinge rods. Two upper hinge rods are hinged on the side surfaces of the two crossbars close to each other. The lower ends of the four upper hinge rods are respectively hinged to the upper ends of the four rotating blocks. Outer plates are hinged on the right side surfaces of the two rotating blocks on the left side. Inner plates are arranged in front of the two outer plates. The two inner plates are respectively slidably inserted into the fronts of the two outer plates. The right ends of the two inner plates are respectively hinged to the left side surfaces of the two rotating blocks on the right side. A plurality of through holes A penetrating up and down are respectively formed on the upper surfaces of the two outer plates. A plurality of through holes B penetrating up and down are formed on the upper surface of the inner plate. Two inserting rods are arranged between the four rotating blocks. The two inserting rods are respectively inserted into the interiors of two of the through holes A and two of the through holes B. The following deficiencies still exist in the above patent: Although the above existing device can effectively support steel components, there is no limiting structure on the support plate for support, which is extremely likely to cause the displacement of the supported steel components. Therefore, a bracket for steel structure engineering is proposed to optimize and solve the above problems. Content of the Utility Model

[0021] The working principle of the utility model is as follows:

[0022]

[0023] When the steel structure engineering support is needed, the operator first moves the device to the position to be supported in the steel structure project by using the walking wheels 5. Then, by rotating the first screw rod 3 through the swivel ring 4, the walking wheels 5 are moved upward and the base 1 is made to fit with the ground. Further, by removing the fixing bolts on the right-angle frame 2, the right-angle frame 2 is separated from the base 1. Subsequently, the device is fixed to the ground by using fixing nail pins through the base 1, thus completing the movement and fixation of the device. Further, by pulling the handle 7 to rotate the first cylinder 6, the first cylinder 6 drives the two second screw rods 10 to rotate by engaging with the two first gears 11 through the annular gear sleeve 9, thereby driving the two threaded barrels 12 on the two second screw rods 10 to move upward simultaneously, and then driving the second cylinder 8 and the fixing frame 13 to move upward. Until the two clamps 18 in the fixing frame 13 are in contact with the outer side of the steel member, then by rotating the third screw rod 14 through the turning handle 15, the two first sliders 17 are moved towards each other, thereby driving the two clamps 18 to clamp and support the steel member. Furthermore, the second slider 19 can be slid on the slide rail outside the fixing frame 13 and limited by the limit bolt, so that the block 20 is clamped in the tooth groove on the second gear 16 to limit the third screw rod 14, thereby completing the reinforcement and support operation of the steel structure member. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
