Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a large-diameter cylindrical steel-clad reinforcement device. Background Art

[0002] Column steel-clad construction is a common and effective reinforcement method. Steel-clad reinforcement has the advantages of simple construction process, quick operation, and high economy, and is widely used in structural reinforcement design. However, when it is specifically applied to the reinforcement of large-diameter cylinders, due to the large rigidity of the reinforced steel plate itself, it is easy to cause quality problems such as loose fit, deviation, and distortion between the steel plate and the structural column. At the same time, the gap between the annular hoop plate and the cylinder is of different sizes, which is easy to cause the quality not meeting the requirements and excessive use of colloidal materials, which is not conducive to construction quality control and construction cost control. Based on this, the utility model designs a column steel-clad reinforcement device under large-diameter cylinder working conditions, which is conducive to improving efficiency and reducing costs while improving construction quality. Utility Model Content

[0003] The utility model aims to address the deficiencies in the prior art and provides a large-diameter cylindrical steel-clad reinforcement device, comprising a structural column, a guide rail vertically arranged along the surface of the structural column being fixed on the outer side of the structural column, the guide rail being fixedly connected to the structural column through a support leg, an annular clamping plate and an extrusion rod being further arranged on the outer side of the structural column, one end of the extrusion rod being located outside the annular clamping plate, a plurality of vertical strips being vertically installed on the surface of the structural column, a plurality of the vertical strips being fixed by an annular hoop plate, the other end of the extrusion rod extending into the annular clamping plate and being able to abut against the annular hoop plate, the annular hoop plate being extruded and fixed by rotating the extrusion rod, and the annular clamping plate being able to move up and down along the guide rail.

[0004] Preferably, the annular clamping plate is composed of two semicircular steel structures, and a plurality of the extrusion rods are evenly arranged at intervals of 30° along the radial direction of the annular clamping plate.

[0005] Preferably, a steel gasket bypassing the vertical strip is provided between the structural column and the annular hoop plate, and the gap between the hoop plate and the structural column is controlled by the steel gasket.

[0006] Preferably, after the annular hoop plate is positioned, the end of the annular hoop plate is fixed to the surface of the vertical steel bar by welding.

[0007] Preferably, the height of the structural column is greater than 3m, and the guide rail is provided with upper, middle and lower legs fixed to the circular structural column, and the legs need to avoid the position where the reinforcing steel plate of the structural column is located.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model mainly solves the problem of realizing precise installation and construction of large-diameter columns under the condition of thick steel plates being wrapped with steel. When large-diameter columns are reinforced with steel wrapping, the annular hoop plates cannot be pre-bent into place at one time. The annular hoop plates themselves have relatively large rigidity, and the gap width between the hoop plates and the structural columns cannot be effectively controlled manually. Through horizontal electric clamps and vertical automatic traction devices, an effective device is formed. The utility model has high construction accuracy, fast installation speed, saves rubber bag materials, and is conducive to the optimization of engineering technology.

[0013] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

[0014] Reference Figure 1 and Figure 2 The utility model discloses a large-diameter cylindrical steel-clad reinforcement device, comprising a structural column 7, a guide rail 2 vertically arranged along the surface of the structural column is fixed on the outer side of the structural column 7, the guide rail is fixedly connected to the structural column through a support leg 1, an annular clamping plate 3 and an extrusion rod 4 are also arranged on the outer side of the structural column, one end of the extrusion rod 4 is located outside the annular clamping plate 3, a plurality of vertical strips are vertically installed on the surface of the structural column, a plurality of the vertical strips 5 are fixed by an annular hoop plate 6, the other end of the extrusion rod 4 extends into the annular clamping plate 3 and can abut against the annular hoop plate 6, the annular hoop plate 6 is extruded and fixed by rotating the extrusion rod 4, and the annular clamping plate 3 can move up and down along the guide rail 2.

[0015] In the utility model, a guide rail frame is first installed on the cylindrical structural column, and aluminum alloy guide rails are arranged on both sides of the structural cylinder. The aluminum alloy guide rails are provided with three legs 1 at the upper, middle and lower positions to be fixed to the circular structural column. The legs 1 are fixed to the structural column with bolts, and the legs 1 need to avoid the position where the reinforcement steel plate is located.

[0016] Install the annular clamp 3 on the guide rail. The annular clamp 3 is two semicircular steel structures. Extrusion rods 4 are evenly arranged at a spacing of 30° along the radial direction. Both ends of the two semicircular steel structures of the annular clamp 3 are fixed by bolts, and the clamp can slide up and down with the guide rail.

[0017] The pre-bent annular hoop plate 6 is passed between the structural column and the annular clamp plate 3, and the annular hoop plate 6 is fitted with the structural column through the extrusion rod 4 on the annular clamp plate 3. During the fitting process, a steel gasket is placed to control the gap between the annular hoop plate 6 and the structural column so that the subsequent glue filling thickness meets the requirements.

[0018] After the annular hoop plate 6 is positioned to meet the requirements, the end of the annular hoop plate 6 is welded and fixed to the vertical strip plate 5 .

[0019] After the annular hoop plate 6 is welded and fixed, the extrusion rod 4 is released, and the annular clamping plate 3 is moved up to the next position where the annular hoop plate 6 needs to be set, and the above operation is repeated to position the annular hoop plate 6.

[0020] After the annular hoop plate 6 is positioned, the annular clamp plate 3 and the guide rail frame are removed, and the reinforcement steel plate of the structural column is glued.

[0022] The utility model is provided with a shaping fixture, and the bending degree of the annular hoop plate 6 and the width of the gap between the annular hoop plate 6 and the structural column are controlled by the extrusion rod 4 provided on the annular clamp plate 3 itself. Compared with the manual installation method, the accuracy is significantly improved, and the colloid material is saved. In particular, the positioning effect is more obvious for steel plates with thicker thickness and greater rigidity.

[0023] The utility model has the characteristics of simple construction, quick installation and disassembly, and turnover. Compared with the traditional construction method, it has high installation accuracy, good quality, cost saving and short construction period.
