Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a steel bar spacing fixing device used for concrete pouring. Background Art

[0002] During the construction process of a building project, it is often necessary to cast columns. To cast columns, it is necessary to pre-set column reinforcement bars distributed on the four sides of a rectangle at the location where the columns are set. There are multiple column reinforcement bars on each side of the rectangle. During casting, the formwork is used to cooperate with the concrete to cover the set column reinforcement bars. The columns are then formed through subsequent concrete curing and formwork removal.

[0003] Proper rebar spacing facilitates concrete pouring and vibration. Building structure design specifications also clearly stipulate the spacing of rebar in concrete columns. If column rebar shifts or spacing changes during concrete pouring, it will affect the quality of the column after pouring. Concrete generates a certain amount of lateral pressure and impact during pouring and vibration. If the rebar is not effectively fixed, it is easy for it to shift and deform, thus changing the designed rebar position and spacing. This not only affects the structural load-bearing performance but may also cause dimensional deviations in the columns, affecting subsequent construction. Fixed rebar spacing can prevent rebar shifting during pouring.

[0004] In order to prevent the column reinforcement from shifting or changing in spacing during concrete pouring, the existing technology generally uses scrap steel bars or steel pipes from the construction site together with wire to bundle the column reinforcement. This is quite random, non-standard, and has different forms. The reinforcement spacing control effect is poor, and it does not conform to the site standardization, making the site appear messy.

The multiple fixing brackets on each fixing rod correspond one-to-one to multiple steel bars preset on a rectangular side of the column position, and the fixing bracket includes an arc bracket and a screw. The arc bracket is a tube with an arc-shaped cross-section. The screw is fixedly connected to the outer wall of the rear side of the arc bracket, and the end of the screw away from the arc bracket is fixedly connected to the fixing rod, and the arc bracket is clamped on the steel bar.

[0007] Furthermore, the fixing rod is provided with a rectangular groove, which is arranged along the length direction of the fixing rod. Multiple fixing brackets are slidably connected in the rectangular groove. The fixing bracket includes a baffle, which is fixedly connected to the end of the screw away from the arc bracket. The screw passes through the rectangular groove, and the baffle is connected to the side wall of the fixing rod away from the steel bar.

[0008] Furthermore, the fixing base includes a nut, the nut is connected to the screw rod, and the fixing rod is clamped between the baffle and the nut.

[0010] Furthermore, the inner height of the rectangular groove is a1, the baffle is a rectangular plate, the height of the baffle is a2, the width of the baffle is b2, b2>a1>a2; the axial direction of the arc holder is the same as the width direction of the baffle, and the axial direction of the arc holder is perpendicular to the height direction of the baffle.

[0021] like Figure 1-Figure 7 As shown, the utility model is a steel bar spacing fixing device used for concrete pouring, which includes a fixing rod 1 and a fixing base 2. The rear end of the fixing base 2 is fixedly connected to the fixing rod 1. Each fixing rod 1 is fixedly connected to a plurality of fixing bases 2. The plurality of fixing bases 2 are linearly evenly distributed along the length direction of the fixing rod 1. The plurality of fixing bases 2 on each fixing rod 1 correspond one to one with a plurality of steel bars preset on a rectangular side of the column position. The fixing base 2 includes an arc base 201 and a screw 202. The arc base 201 is a tubular with an arc-shaped cross section. The screw 202 is fixedly connected to the outer wall of the rear side of the arc base 201. The screw 202 is away from the arc base 20 One end of 1 is fixedly connected to the fixing rod 1, and the arc clamping seat 201 is clamped on the steel bar; the fixing rod 1 is provided with a rectangular groove 101, which is arranged along the length direction of the fixing rod 1, and multiple fixing clamping seats 2 are slidably connected in the rectangular groove 101, and the fixing clamping seat 2 includes a baffle 203, which is fixedly connected to one end of the screw 202 away from the arc clamping seat 201, the screw 202 passes through the rectangular groove 101, and the baffle 203 is connected to the side wall of the fixing rod 1 away from the steel bar; the fixing clamping seat 2 includes a nut 204, the nut 204 is connected to the screw 202, and the fixing rod 1 is clamped between the baffle 203 and the nut 204.

[0022] like Figure 2 As shown, before pouring the columns, it is necessary to preset the steel bars distributed on the four sides of the rectangle at the location where the columns are set. There are multiple column steel bars on each side of the rectangle, such as Figure 2 As shown, in this embodiment, six steel bars are provided on each side of the rectangle for illustration. The specific number and specific spacing of the preset steel bars are determined according to the construction design requirements and the building structure design specifications. Changes in the number and spacing of the preset steel bars do not affect the understanding of the present invention.

[0023] The arc clamp 201 is a tubular shape with an arc-shaped cross-section so that the steel bars can be conveniently clamped through the arc-shaped opening. If the arc clamp 201 is shaped as a round tube, the arc clamp 201 can only be inserted into the steel bars from the end portion of the steel bars. Since the steel bars have a certain height and the two ends of the steel bars may be connected to certain cast building components, the arc clamp 201 in the shape of a round tube is inconvenient to use or cannot be used.

[0024] The inner height of the rectangular groove 101 is greater than the outer diameter of the screw 202; the inner height of the rectangular groove 101 is a1, the baffle 203 is a rectangular plate, the height of the baffle 203 is a2, the width of the baffle 203 is b2, b2>a1>a2; the axial direction of the arc holder 201 is the same as the width direction of the baffle 203, and the axial direction of the arc holder 201 is perpendicular to the height direction of the baffle 203.

[0025] Since the axial direction of the arc clamp 201 is the same as the width direction of the baffle 203, and the axial direction of the arc clamp 201 is perpendicular to the height direction of the baffle 203, when the arc clamp 201 is clamped on the steel bar, the width direction of the baffle 203 is vertically clamped on the fixing rod 1. Since b2>a1, the fixing clamp 2 will not fall out of the rectangular groove 101 at this time. The nut 204 is then used to stably connect the fixing clamp 2 to the fixing rod 1, and multiple arc clamps 201 and multiple steel bars are connected in turn to fix the steel bar gap. For different steel bar spacings, as long as the width of the rectangular groove 101 can meet the use requirements, the arc clamp 201 slides in the rectangular groove 101 during installation to adapt to different steel bar spacings.

[0026] When the casting is completed and the utility model is disassembled, the multiple arc brackets 201 are separated from the multiple steel bars, and the fixing rod 1 and the fixing bracket 2 can be removed. At this time, the fixing rod 1 and the fixing bracket 2 are still connected together. Loosen the nut 204 of each fixing bracket 2, and then rotate the fixing bracket 2 90°. Figure 6 and Figure 7 As shown, the width direction of the baffle 203 is parallel to the width direction of the rectangular groove 101. Since a1>a2, the baffle 203 can be removed from the rectangular groove 101, thereby separating the fixing rod 1 and the fixing base 2. Figure 7 The direction of the middle arrow indicates the direction of movement when the fixed card holder 2 is disassembled.

[0027] The inner width of the rectangular groove 101 is b1. If the number of the plurality of fixing sockets 2 connected to a fixing rod 1 is n, then n×b2<b1.

[0028] n×b2<b1 ensures that the connection between the plurality of fixed holders 2 and the fixed rod 1 does not cause jamming or interference.

[0029] Since the preset steel bars are distributed on the four sides of a rectangle, the four sides of the rectangle need to be connected to the present invention to fix the steel bar spacing. If steel bars are set at the four corners of the rectangle, the steel bars at the four corners need to be connected to the fixing rods 1 in two directions at the same time, and the steel bars at the four corners need to be connected to two fixing brackets 2. In order to prevent position interference, the fixing brackets 2 and the fixing rods 1 connected to the steel bars at the four corners can be set at different heights, such as Figure 1 shown.

[0030] For ease of use, scale lines can also be set on the fixing rod 1 to determine the spacing between steel bars.

[0031] The utility model can effectively control the spacing between steel bars to prevent it from changing, has a simple structure, is easy to connect, and has high work efficiency, so that the tool for fixing the spacing between steel bars is planned, meets the requirements of safe and civilized construction on site, has low production cost, is reusable, and can be applied to steel bars of different spacings and different quantities, and has promotion value.
