Description

Technical Field

[0001] The utility model relates to the technical field of steel-bonded reinforced column construction, in particular to a steel plate fixing device for steel-bonded reinforced column construction. Background Art

[0002] Steel bonding reinforcement is also called steel plate bonding reinforcement. It is to use high-performance epoxy adhesive to bond the steel plate to the surface of the concrete component, so that the steel plate and the concrete form a unified whole, thereby using the good tensile strength of the steel plate to achieve the purpose of enhancing the bearing capacity and rigidity of the concrete component. When the steel plate and the concrete component are bonded, it is strictly forbidden to be disturbed while waiting for the epoxy adhesive to cure. Therefore, when the four corners of the concrete component of the column structure are reinforced with steel, the steel angle plate needs to be fixed to prevent the steel angle plate from being skewed, dislocated, or tipped over by gravity during the curing of the epoxy adhesive, resulting in the failure of the steel bonding reinforcement of the concrete component of the column structure.

[0003] In the existing steel-bonded reinforcement column construction (i.e., the construction of steel-bonded reinforcement at the four corners of concrete components of column structures), steel pipes and tension screws are used to fix the steel angle plates at the four corners of beams and columns. This process is cumbersome and can easily cause excessive local stress on the steel angle plates, resulting in squeezing and dislocation between the steel angle plates and concrete, and then causing the epoxy adhesive between the steel angle plates and the beams and columns to be lost. In addition, for operators with low proficiency, the construction process of steel pipes and tension screws will seriously affect the installation time, thereby delaying the construction period. Summary of the invention

[0004] The utility model aims to provide a steel plate fixing device for the construction of steel-bonded reinforcement columns in view of the defects of the prior art.

[0005] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0006] The utility model discloses a steel plate fixing device for the construction of a steel-bonded reinforcement column, comprising a first fixing part and a second fixing part; wherein the first fixing part is a pair of L-shaped plates snapped onto the two left corners of the steel-bonded reinforcement column, and the second fixing part is a straight plate horizontally attached to the right side of the steel-bonded reinforcement column; the long sides of the two L-shaped plates overlap each other, and a first connecting long hole is opened at the overlapping part along the length direction, and bolt connectors are passed through the two first connecting long holes; a connecting screw is fixed on the short sides of the two L-shaped plates respectively, and the two connecting screws pass horizontally through the second connecting long hole opened on the straight plate along the length direction, and a fastening nut is screwed on the passing end.

[0007] Furthermore, the L-shaped plate and the straight plate are both made of steel plates with a width of 50 mm and a thickness of 10 mm.

[0008] Furthermore, the length of the first connecting long hole is 200 mm and the width is 22 mm; the bolt connector is composed of an M20 bolt passing through the two first connecting long holes and a fixing nut adapted to be screwed on the M20 bolt.

[0009] Furthermore, the second connecting long holes are two symmetrically opened on the straight plate, and the length of the two second connecting long holes is 150 mm and the width is 22 mm; the connecting screw is an M14 screw, which is welded to the outer surface of the short side of the L-shaped plate.

[0010] The utility model has the advantages of simple structure and easy processing and manufacturing. It not only has low manufacturing cost, but also can be used repeatedly and has strong practicality. In addition, the operation of the entire device during actual installation and use is also very simple. It can use two L-shaped plates and a straight plate to enclose a fixed frame of a rectangular structure, and can be reasonably adjusted according to the specific size of the bonded steel reinforcement column. It can easily enclose the outer periphery of the bonded steel reinforcement column to provide a balanced and stable clamping force for the steel angle plates at the four corners of the columnar concrete member, effectively avoiding excessive local stress on the steel angle plates, preventing the steel angle plates and the columnar concrete member from being squeezed and dislocated, and avoiding the loss of epoxy adhesives between the steel angle plates and the columnar concrete member due to excessive pressure, thereby improving the construction efficiency of the bonded steel reinforcement column, ensuring the construction quality, and being suitable for promotion and application.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1-3As shown, the steel plate fixing device for the construction of the bonded steel reinforcement column described in the utility model includes a first fixing part for clamping and fixing the steel angle plates at the two left corners of the bonded steel reinforcement column 100, and a second fixing part for clamping and fixing the steel angle plates at the two right corners of the bonded steel reinforcement column 100. The first fixing part and the second fixing part are used in combination to form a rectangular structure fixing frame that is ring-fixed on the outer periphery of the bonded steel reinforcement column 100, providing a balanced and stable clamping force for the steel angle plates at the four corners.

[0016] Specifically, the first fixing part is a pair of L-shaped plates 1 that are snapped on the two corners of the left side of the steel reinforcement column 100, and the second fixing part is a straight plate 2 that is horizontally attached to the right side of the steel reinforcement column 100. The L-shaped plate 1 and the straight plate 2 are both made of steel plates with a width of 50 mm and a thickness of 10 mm.

[0017] The long sides of the two L-shaped plates 1 overlap each other, and a first connecting long hole 3 is opened at the overlapping portion along the length direction, and a bolt connector 4 is passed through the two first connecting long holes 3. The length of the first connecting long hole 3 is 200 mm and the width is 22 mm. The bolt connector 4 is composed of an M20 bolt passed through the two first connecting long holes 3 and a fixing nut adapted to be screwed on the M20 bolt. The overlapping length of the long sides of the two L-shaped plates 1 can be adjusted according to the actual size of the bonded steel reinforcement column 100, and then the long sides of the two L-shaped plates 1 are fixedly connected together by the bolt connector 4 to form a fixed connection between the two L-shaped plates 1.

[0018] A connecting screw 5 is fixed on the short sides of the two L-shaped plates 1, and a second connecting long hole 6 matching the connecting screw 5 is opened on the straight plate 2 along the length direction. The axial direction of the two connecting screws 5 is consistent with the length direction of the short sides of the two L-shaped plates 1, and they pass horizontally through the second connecting long hole 6 opened on the straight plate 2, and a fastening nut 7 is screwed on the passing end of each connecting screw 5. Among them, the connecting screw 5 is an M14 screw, which is double-sided welded and fixed on the outer surface of the short side of the L-shaped plate 1, and the length of the weld is 15 times the length of the rod diameter of the connecting screw 5; in addition, there are two second connecting long holes 6 symmetrically opened on the straight plate 2, and the length of each second connecting long hole 6 is 150mm and the width is 22mm, which ensures that the connecting screw 5 passing through it can be adjusted and translated according to the actual size of the bonded steel reinforcement column 100, while avoiding opening a whole long hole on the straight plate 2 to reduce the rigidity of the straight plate 2.

[0019] When in use, just snap the two L-shaped plates 1 into the two left corners of the bonded steel reinforcement column 100, and fix the long sides of the two L-shaped plates 1 together through the bolt connector 4, and then set the straight plate 2 on the right side of the bonded steel reinforcement column 100, so that the connecting screws 5 on the two L-shaped plates 1 just pass through the two second connecting long holes 6 on the straight plate 2, and fix them with fastening nuts 7, quickly complete the installation of the entire steel plate fixing device, easily surround the outer periphery of the bonded steel reinforcement column 100 to provide a balanced and stable clamping force for the steel angle plates at the four corners, effectively avoid excessive local stress on the steel angle plates, prevent the steel angle plates and the columnar concrete components from being squeezed and dislocated, and avoid the loss of epoxy adhesive between the steel angle plates and the columnar concrete components due to excessive pressure, thereby improving construction efficiency, ensuring construction quality, and being suitable for promotion and application.
