Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an adjustable positioning hoop for a rectangular column. Background Art

[0002] Rectangular columns are a common form of frame columns. In the existing technology, the extended part of the main reinforcement of rectangular columns is generally positioned and fixed with several circles of stirrups. However, the existing positioning and fixing method has poor restraint force, cumbersome construction, and low positioning accuracy. During concrete pouring, it is easy to cause the main reinforcement to tilt, uneven spacing, and reduced protective layer, thereby affecting the stress state of the frame column structure and being unfavorable for the subsequent concrete pouring and vibration. To this end, we propose an adjustable positioning hoop for rectangular columns. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the utility model provides an adjustable rectangular column positioning hoop which is reusable, easy to install and disassemble, and has accurate positioning.

[0004] The technical solution of the utility model to solve the above problems is:

[0005] A rectangular column adjustable positioning hoop comprises two transverse square tubes, two longitudinal square tubes, positioning bolts and fixing bolts. First sliding grooves are vertically opened at both ends of the two transverse square tubes and the two longitudinal square tubes, and second sliding grooves are horizontally opened in the middle of the two transverse square tubes and the two longitudinal square tubes. The transverse square tubes are arranged at the upper or lower part of the longitudinal square tubes. The transverse square tubes and the longitudinal square tubes are fixed by fixing bolts passing through the corresponding first sliding grooves. The two transverse square tubes and the two longitudinal square tubes together form a "well"-shaped closed rectangular frame. Several pairs of mutually parallel positioning bolts are arranged in the second sliding grooves. The bolt heads of the positioning bolts face outward, and the bolt rods of the positioning bolts pass through the second sliding grooves and are fixed with nuts.

[0006] Furthermore, the length of the positioning bolt is set to the sum of the width of the corresponding square tube and the diameter of the main reinforcement of the rectangular column, plus a margin of 1 to 10 mm.

[0007] Furthermore, the number of the positioning bolts is (n-4)×2, where n is the number of main reinforcements of the rectangular column.

[0008] The utility model is suitable for the construction of rectangular columns with different sizes, main reinforcement numbers and spacing arrangements. It has the characteristics of adjustable size, easy installation and disassembly, accurate positioning, and reusability. It can effectively control the spacing of the main reinforcements of the rectangular columns, prevent problems such as main reinforcement deviation and uneven spacing, and reduce construction costs and improve construction efficiency while ensuring construction quality.

[0012] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0013] Examples, such as Figure 1 and Figure 2 As shown, the positioning hoop 7 includes two transverse square tubes 1, two longitudinal square tubes 2, positioning bolts 3 and fixing bolts 4. A first sliding groove 5 is vertically opened at both ends of the two transverse square tubes 1 and the two longitudinal square tubes 2, and a second sliding groove 6 is horizontally opened in the middle of the two transverse square tubes 1 and the two longitudinal square tubes 2. The transverse square tubes 1 are arranged at the lower part of the longitudinal square tubes 2, and are staggered and perpendicular to each other to form a "well"-shaped closed rectangular frame. The transverse square tubes 1 and the longitudinal square tubes 2 are fixed by fixing bolts 4 passing through the corresponding first sliding groove 5; a plurality of pairs of mutually parallel positioning bolts 3 are arranged in the second sliding groove 6, the bolt heads of the positioning bolts 3 face outward, and the bolt rods of the positioning bolts 3 pass through the second sliding groove 6 to cooperate with the nuts for fixation. When the nuts are loosened, the positioning bolts 3 can be moved and adjusted along the second sliding groove 6 to adapt to the position of the main reinforcement 8 of the rectangular column.

[0014] like Figure 2 As shown, the main reinforcement 8 of the rectangular column is fixed on the inner side of the positioning hoop 7, the main reinforcement 8 of the rectangular column at the four corner ends is fixed on the four corner ends of the positioning hoop 7, and the remaining main reinforcement 8 of the rectangular column is embedded between each pair of positioning bolts 3. The main reinforcement 8 of the rectangular column and the positioning hoop 7 are fixed by steel wire binding.

[0015] During the installation or disassembly process, the positioning hoop 7 can slide in the vertical direction along the main reinforcement 8 of the rectangular column, and a certain distance is left between the positioning bolt 3 and the main reinforcement 8 of the rectangular column, making the installation and disassembly of the positioning hoop 7 more convenient and reducing the jamming between the positioning hoop 7 and the main reinforcement 8 of the rectangular column. When the positioning hoop 7 is inserted into the main reinforcement 8 of the rectangular column, the positioning bolt 3 is further adjusted to clamp the main reinforcement 8 of the rectangular column, thereby realizing the positioning of the main reinforcement 8 of the rectangular column. The positioning hoop 7 has the characteristics of adjustable size, easy installation and disassembly, accurate positioning, and reusability. It can effectively control the spacing of the main reinforcement 8 of the rectangular column, prevent problems such as main reinforcement displacement and uneven spacing, improve construction efficiency, and ensure the installation quality of the main reinforcement 8 of the rectangular column.

[0016] In this embodiment, the length of the positioning bolt 3 is the width of the corresponding square tube + the diameter of the rectangular column main reinforcement 8 + 1 to 10 mm.

[0017] In this embodiment, the number of the positioning bolts 3 is (n-4)×2, where n is the number of the rectangular column main reinforcements 8 .
