Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel structure fixing device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel structures are usually connected by fixing devices, and the steel structure fixing devices in the prior art are easy to fall off.

[0003] After searching, a steel structure (publication number CN209339311U) is now disclosed. By adopting the above-mentioned scheme, the crossbeam of the steel structure is U-shaped, which saves the use of materials. At the same time, a positioning groove matching the column is provided on the inner side of the crossbeam. When installing the crossbeam, the upper part of the column is embedded in the positioning groove, and the inner wall of the positioning groove presses and supports the side wall of the column, thereby improving the strength of the column and the crossbeam and improving the installation efficiency of the crossbeam.

[0004] However, although the above technical solution can effectively improve the efficiency of beam installation, since the device is connected to the steel structure by threaded connection, it is easy to fall off during use, thereby affecting the safety of pedestrians. For this reason, we provide a steel structure fixing device. Utility Model Content

[0009] Preferably, a handle seat is provided in the middle of one end of the threaded rod, and a second movable block is movably connected to the middle of the other end of the threaded rod.

[0010] Preferably, the middle part of one end of the second movable block is movably connected to the first movable block, and the outer part of one end of the first movable block passes through the interior of the clamping box.

[0011] Preferably, a mounting plate is provided in the middle of one end of the first movable block, the inner sides of both ends of the mounting plate are connected with clamps, the mounting plate and the clamp are in a horizontal and parallel state as a whole, and the two ends of the mounting plate are respectively connected with the clamp and the first movable block.

[0012] Preferably, a fixing seat is penetrated and connected to the outside of one end of the column steel, and a square steel is penetrated and connected to the inside of one end of the fixing seat.

[0014] The working principle and beneficial effects of the utility model are:

[0015] The utility model inserts the column steel into the bottom of the fixed base, and the column steel moves downward to the lowest end inside the fixed base. When the column steel moves to the lowest end inside the fixed base, the limit block is clamped into the first limit groove through the first limit groove opened at the bottom. When the limit block is clamped into the first limit groove, the movable clamping block begins to shrink toward the internal contraction chamber of the limit block. When the movable clamping block shrinks toward the inside of the limit block, it squeezes the spring arranged inside the contraction chamber. When the movable clamping block is completely retracted into the inside of the limit block, the limit block just completely fits into the inside of the first limit groove. When the limit block just fits into the inside of the first limit groove, the movable clamping block loses the squeezing force and pops outwards under the action of the spring. The movable clamping block directly pops out of the inside of the limit block and fits into the second limit groove, thereby limiting and fixing the column steel, thereby achieving the effect that the steel structure is not easy to fall off and affect the safety of pedestrians.
