Technical Field

[0001] The invention relates to the technical field of finishing rolled threaded steel lifting, in particular to a finishing rolled threaded steel lifting device and a construction method. Background Art

[0002] With the rapid development of my country's economy, the construction of transportation infrastructure has also developed rapidly. At the same time, the number of bridges built on rivers and lakes in my country has also increased. As we all know, to build a bridge, you must first build piers in the water. To build piers, you must use steel box cofferdams in the water to drain the water before construction can begin.

[0003] However, the existing fine-rolled threaded steel lifting device and construction method have the following problems during use: when traditional fine-rolled threaded steel is lifted, the lifting contact area is small, the installation coefficient is low, and it is easy to fall, so how to lift it and fix it in a limited space during installation is very important. Summary of the Invention

[0004] The purpose of the present invention is to provide a finishing rolled threaded steel lifting device and a construction method to solve the related problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a high-quality rolled threaded steel lifting device and construction method, comprising a perforated original disk, a clamping piece and a high-quality rolled threaded steel body, a fixing hole being opened inside the perforated original disk, a high-quality rolled threaded steel body passing through the fixing hole being arranged inside the perforated original disk, and a clamping piece passing through the fixing hole being sleeved on the outer wall of the high-quality rolled threaded steel body, a fixing nut being provided on the outer wall of the high-quality rolled threaded steel body, and the interior of the fixing nut being engaged with the outer wall of the high-quality rolled threaded steel body, a limiting hole being opened inside the fixing nut and the high-quality rolled threaded steel body, and an iron wire passing through the limiting hole being sleeved on the outer wall of the high-quality rolled threaded steel body.

[0006] As a preferred solution of the hoisting device and construction method of the finished rolled threaded steel bar of the present invention, a hoisting hole is opened inside the perforated original plate.

[0007] As a preferred solution of the finishing-rolled threaded steel lifting device and construction method of the present invention, the inner wall of the clamp is installed with reinforcing ribs, and the inner wall of the reinforcing rib is provided with a positioning clamping steel sheet in contact with the outer wall of the finishing-rolled threaded steel body.

[0008] As a preferred solution of the hoisting device and construction method of the finished rolled threaded steel bar of the present invention, the reinforcing rib is fan-shaped.

[0009] As a preferred solution of the present invention, a finishing rolled threaded steel lifting device and construction method comprises the following steps: S1. Drill holes at the location where lifting is required and create two sets of limit holes. S2. Install the fixing nut on the required lifting position of the original plate with holes, pass the iron wire through the limiting hole and then wrap it to the outer wall of the finished rolled threaded steel body; S3. Insert the holed original plate through the body of the finished rolled threaded steel bar and place it above the fixing nut. Then insert the clip into the fixing hole. S4. Twist the other set of fixing nuts to the position above the clip on the outer wall of the finished threaded steel body. Then, pass the wire through the limiting hole and wrap it around the outer wall of the finished threaded steel body. Positioning is complete. S5. Insert the lifting hook through the lifting hole and pull it vertically upwards to lift.

[0010] Beneficial effects of the hoisting device and construction method of fine-rolled threaded steel bars of the present invention: The present invention pulls the position of the holed original disk upward to extrude the clip, which is squeezed toward the middle position, positioning the clamping steel sheet to fit the outer wall of the fine-rolled threaded steel body, while the reinforcing ribs increase the strength of the clip position. Then, the clip position can be further positioned by two sets of upper and lower position fixing nuts, and the lifting position of the holed original disk can be further limited. In a limited space, a wire tie is used to pass through the limiting hole to prevent the fixing nut from sliding, thereby improving stability during lifting. BRIEF DESCRIPTION OF THE DRAWINGS
