Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices, in particular to a quick and easy fixing device for steel structure installation. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. Welds, bolts or rivets are usually used to connect between the components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel pipes are often used to build steel pipe scaffolds in the construction of housing construction, tunnels, water conservancy, chemical industry, coal, national defense and other projects. It has a hollow cross-section, and the length of the steel material is greater than the diameter or circumference. According to the cross-sectional shape, it is divided into circular, square, rectangular and special-shaped steel pipes.

[0003] A patent with a publication number of CN208152593U is disclosed in the prior art. The solution includes a carrier, a mounting member, a first positioning member and a second positioning member. The carrier has a mounting groove and at least two first mounting holes. The mounting member is fixedly installed on the carrier and located in the mounting groove. A clamping groove is provided on the mounting member. The first positioning member is installed on the mounting member. A second mounting hole is provided on the first positioning member. The second positioning member is installed in the clamping groove. A third mounting hole is provided on the second positioning member. During operation, two steel pipes are respectively inserted into the first positioning member and the second positioning member to realize the preliminary positioning of the steel pipes and the carrier. Then, bolts are inserted into the corresponding holes and the bolts are screwed to fix the steel pipes, the carrier and the positioning members together, thereby realizing the installation of the two steel pipes. At the same time, the second positioning member is slidably arranged on the mounting member, thereby changing the distance between the second positioning member and the bottom of the mounting groove, and steel pipes with different thicknesses can be installed, and the use range is wider.

[0004] With the use of the existing device, the deficiencies of this technology have gradually emerged, mainly manifested in the following aspects:

[0005] First, when operators assemble the steel structure pipe rack, since there is often a certain distance to be staggered between the two pipe racks, it increases the assembly difficulty of the steel structure pipe rack for the operators.

[0006] Second, when operators dock two steel structure pipe racks, they need to use a connecting seat. Since the notch of the connecting seat is the same size as the steel structure pipe rack, it is difficult to quickly connect the steel structure pipe rack, which is time-consuming and laborious.

[0007] In summary, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve. Summary of the Utility Model

[0008] In view of the defects in the prior art, the utility model solves the problems that when an operator assembles a steel structure pipe rack in the traditional technology, since there is often a need to stagger a certain distance between two pipe racks, it increases the difficulty of assembling the steel structure pipe rack by the operator; and when the operator docks two steel structure pipe racks, a connecting seat needs to be used. Since the notch of the connecting seat is the same size as the steel structure pipe rack, it is difficult to quickly connect the steel structure pipe rack, which is time-consuming and laborious.

Second stop knobs are horizontally threadedly connected to the opposite outer walls of the pipe rack above respectively. The end of the second stop knob extends into the second limit ring groove.

[0016] As an optimized scheme, the upper end of the lower guiding column is tapered. A lower insertion slot is arranged in the lower connecting seat. The lower insertion slot includes a lower tapered slot section and a lower straight hole section that match the lower guiding column.

[0017] As an optimized scheme, third stop knobs are horizontally threadedly connected to the opposite outer walls of the lower connecting seat respectively. A third limit ring groove is formed on the lower guiding column. The end of the third stop knob extends into the third limit ring groove.

[0018] As an optimized solution, a fourth limit ring groove is formed on the outer wall of the lower guide post near the lower end, and fourth stop knobs are horizontally and threadedly connected to the opposite outer walls of the lower pipe rack below, and the ends of the fourth stop knobs extend into the fourth limit ring groove.

[0019] As an optimized solution, the adjusting structure includes a driving block fixed to the lower surface of the upper sliding seat, a rectangular sliding groove is formed on the lower surface of the lower sliding seat, a screw rod is horizontally rotatably arranged in the rectangular sliding groove, and the screw rod is threadedly connected to the driving block.

[0020] As an optimized solution, one end of the screw rod extends to the outside of the lower sliding seat and is fixed with a rectangular driving handle.

[0021] As an optimized solution, two locking knobs are threadedly connected to the lower surface of the lower sliding seat. The two knobs are respectively located on both sides of the screw rod and are in the diagonal direction of the rectangular sliding groove. The upper ends of the two locking knobs abut against the lower surface of the upper sliding seat.

[0022] As an optimized solution, a conical section is fixed to the upper end of the locking knob, and a plurality of locking grooves matching the conical section are arranged side by side on the lower surface of the upper sliding seat along its sliding direction.

[0023] Compared with the prior art, the beneficial effects of the present utility model are:

[0024] When assembling and docking two pipe racks, first pre-connect the upper guide post and the lower guide post to the opposite ends of the two pipe racks and fix them with corresponding stop knobs. When docking the pipe rack with the connecting seat, use the conical section on the guide post to achieve guidance, and it can be quickly inserted into the insertion groove in the connecting seat. Then use the corresponding stop knobs to fix the connecting column and the connecting seat to achieve the connection of the three. The conical setting can achieve guidance, facilitating the quick docking of the pipe rack and the connecting seat, which is labor-saving and fast;
