Description

Technical Field

[0001] The utility model relates to the field of construction auxiliary components, in particular to a device for controlling the spacing of steel bars. Background Art

[0002] In construction, specifically for precast concrete structures, when tying steel bars, due to the relatively long length of the steel bars, whether the spacing between the steel bars during tying meets the construction requirements, and whether the steel bars are in the correct position that meets the construction requirements in the concrete structure during concrete pouring are important factors determining the quality of the concrete structure. Therefore, it is necessary to control and check the spacing of the steel bars.

[0003] Currently, specifically during the construction process, the inspection of the steel bar spacing is mainly carried out through manual measurement. This causes that in actual operation, when using the manual measurement method to control the steel bar spacing, the staff needs to carry a tape measure with them, and continuous measurement at multiple points is required to ensure the uniformity of the steel bar spacing. The workload is relatively large, which will affect the construction progress. Content of the Utility Model

[0004] The purpose of the present utility model is to provide a device for controlling the spacing of steel bars to solve the above problems. A spacing control component is installed between the two sides of the U-shaped bracket. After adjusting the two moving seats of the spacing control component to be consistent with the spacing that meets the construction requirements during steel bar tying and locking, by placing and comparing the two moving seats in the limiting grooves above the adjacent steel bars on both sides respectively, it can be visually measured and checked whether the spacing of the adjacent steel bars on both sides meets the construction requirements. At the same time, by clamping the adjacent steel bars on both sides in the limiting grooves at both positions respectively, the spacing of the adjacent steel bars on both sides can be corrected and controlled to meet the construction requirements. The measurement, inspection and control methods for the spacing of the adjacent steel bars on both sides are simple and easy to implement, as described in detail below.

[0005] To achieve the above purpose, the present utility model provides the following technical solutions:

[0006] The device for controlling the spacing of steel bars provided by the present utility model includes a U-shaped bracket. The U-shaped bracket is arranged upside down and the horizontal part at the top is arranged horizontally. A spacing control component is installed between the two vertical parts of the U-shaped bracket to measure and check whether the spacing of the adjacent steel bars on both sides meets the construction requirements through the spacing control component and correct and control the spacing of the adjacent steel bars on both sides to meet the construction requirements.

[0007] Preferably, the spacing control component includes a screw rod and a moving seat. The screw rod is horizontally fixed between the vertical parts on both sides of the U-shaped bracket. The number of moving seats is two and they are respectively located on both sides of the screw rod. A matching hole is horizontally formed in the middle of each moving seat, and each moving seat is sleeved around the screw rod in a manner of coaxial sliding fit through the matching hole. At the same time, limit nuts are coaxially engaged at the positions on both sides of the moving seat with respect to the screw rod. A limiting groove for limiting and clamping the steel bar is longitudinally formed on the bottom surface of each moving seat, and the limiting groove is a through groove longitudinally.

[0008] Preferably, the bottom ends of the limiting grooves are both open, the lower half of the limiting groove is a vertical groove, and the upper half of the limiting groove is an isosceles triangle groove with the pointed end facing downwards.

[0009] Preferably, a guide rod is horizontally fixed between the vertical parts on both sides of the U-shaped bracket at a position above the screw rod. A guiding hole is horizontally formed in the upper part of each moving seat, and the guide rods pass through the guiding holes at both sides in a manner of horizontal sliding fit.

[0010] Preferably, a scale ruler for indicating the length horizontally is printed on the front part of the periphery of the guide rod, and the graduation value of the scale ruler is 1 mm.

[0011] Preferably, a control opening is longitudinally formed in the upper part of the front surface of each moving seat, and the control opening is vertically and communicatively connected with the corresponding guiding hole. A reference rod is vertically fixed at the front part of the control opening, and the reference rods are located in the same vertical direction as the top pointed ends of the corresponding limiting grooves below.

[0012] Preferably, the limit nuts are both hand-tightening knurled nuts.

[0013] Preferably, handles for convenient holding are fixedly installed on both sides of the top surface of the U-shaped bracket, and an observation opening for observing the spacing control component is formed in the middle of the top surface of the U-shaped bracket.

[0014] When using the device for controlling the steel bar spacing, specifically during the process of measuring, checking, and controlling the steel bar spacing, since the spacing control component is installed between the two sides of the U-shaped bracket, after adjusting the two moving seats of the spacing control component to have the same spacing as the construction requirement during steel bar bundling and locking them, by placing and comparing the two moving seats on the upper sides of the adjacent steel bars on both sides through the limiting grooves respectively, it is possible to visually measure and check whether the spacing of the adjacent steel bars on both sides meets the construction requirements.

[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope protected by the present utility model.

[0028] See Figures 1-6As shown in the figure, the utility model provides a device for controlling the spacing of steel bars, which includes a U-shaped bracket 1. The U-shaped bracket 1 is arranged upside down, and the horizontal part at the top is arranged horizontally. A spacing control component 2 is installed between the two vertical parts of the U-shaped bracket 1, which is used to measure and check whether the spacing between two adjacent steel bars on both sides meets the construction requirements through the spacing control component 2 and correct and control the spacing between two adjacent steel bars on both sides to meet the construction requirements. Specifically, the spacing control component 2 includes a screw rod 201 and a moving seat 202. The screw rod 201 is horizontally fixed between the two vertical parts of the U-shaped bracket 1. The number of moving seats 202 is two and they are respectively located on both sides of the screw rod 201. A matching hole 207 is horizontally opened in the middle of each moving seat 202, and each moving seat 202 is sleeved around the screw rod 201 in a way of coaxial sliding fit through the matching hole 207. At the same time, limit nuts 203 are coaxially engaged at both positions of the screw rod 201 on both sides of the moving seat 202. A limiting groove 204 for limiting and clamping the steel bars is longitudinally opened on the bottom surface of each moving seat 202, and the limiting groove 204 is a through groove longitudinally. The function of such a setting is that after adjusting the two moving seats 202 of the spacing control component 2 to have the same spacing as the spacing that meets the construction requirements during steel bar bundling and locking, by respectively placing and comparing the limiting grooves 204 of the two moving seats 202 above the two adjacent steel bars on both sides, it can be directly measured and checked whether the spacing between the two adjacent steel bars on both sides meets the construction requirements. At the same time, by respectively clamping the two adjacent steel bars with the limiting grooves 204 at both positions, the spacing between the two adjacent steel bars on both sides can be corrected and controlled to meet the construction requirements. The method of measuring, checking and controlling the spacing between two adjacent steel bars is simple and easy to implement. More specifically, by sliding the moving seat 202 along the screw rod 201 through the matching hole 207 and pressing the limit nuts 203 at both positions of the moving seat 202 on the surface of the moving seat 202, the distance between the two moving seats 202 can be adjusted and locked. The method of adjusting the distance between the two moving seats 202 is simple and easy to operate.

[0029] See Figures 1-3As shown in the figure, the following optimizations are made to the spacing control component 2 and the U-shaped bracket 1 respectively. Specifically for the spacing control component 2, the bottom ends of the limit slots 204 are all open, and the lower half of the limit slot 204 is a vertical slot, and the upper half of the limit slot 204 is an isosceles triangle slot with the pointed end facing downwards. This setting makes it convenient for the limit slot 204 to stably limit and hold the steel bar by descending from top to bottom. At the same time, the isosceles triangle slot in the upper half of the limit slot 204 can also make the axis of the steel bar and the pointed end at the top of the limit slot 204 in the same direction when pressing the top of the outer periphery of the steel bar. Optionally, a guide rod 206 is horizontally fixed between the two vertical parts on both sides of the U-shaped bracket 1 above the screw rod 201. The upper parts of the moving seats 202 are all provided with guide holes 205 in the horizontal direction, and the guide rods 206 all pass through the guide holes 205 at both side positions in a horizontally sliding fit manner. This setting makes it convenient to guide and correct the horizontal movement adjustment process of the moving seat 202 by sliding the guide hole 205 along the guide rod 206 horizontally, avoiding the mating hole 207 of the moving seat 202 from rotating and misaligning around the screw rod 201.

[0030] At the same time, optionally, a scale ruler 208 for indicating the length horizontally is printed on the front part of the periphery of the guide rod 206, and the graduation value of the scale ruler 208 is 1 mm. Control openings 209 are all provided in the longitudinal direction on the upper part of the front surface of the moving seat 202, and the control openings 209 are perpendicularly communicated with the corresponding guide holes 205. Reference rods 2010 are all vertically fixed at the front part of the control openings 209, and the reference rods 2010 are all in the same vertical direction as the pointed ends at the tops of the corresponding limit slots 204 below. This setting makes it convenient to make the reference rods 2010, the pointed ends at the tops of the limit slots 204 and the axis of the steel bar in the same vertical direction. Then, during the process of adjusting the horizontal movement of the moving seat 202 along the screw rod 201, the distance between the two moving seats 202 can be intuitively quantitatively controlled by the way of the reference rod 2010 comparing the scale value of the scale ruler 208. Further optionally, the limit nuts 203 are all hand-twist knurled nuts, so that the limit nuts 203 can be directly twisted by hand-twisting, which is convenient to twist the limit nuts 203 to horizontally move along the screw rod 201 and flexibly change the position.

[0031] Specifically for the U-shaped bracket 1, handles 102 for convenient holding are fixedly installed on both sides of the top surface of the U-shaped bracket 1. An observation opening 101 for observing the spacing control component 2 is provided in the middle of the top surface of the U-shaped bracket 1. Preferably, the handle 102 is a U-shaped part. This setting makes it convenient to drive the U-shaped bracket 1 to move by holding the handles 102 with both hands respectively to smoothly use the spacing control component 2. At the same time, it is convenient to check the use situation of the spacing control component 2 through the observation opening 101, and further convenient to use the spacing control component 2 at the construction site to measure and control the spacing between two adjacent steel bars.

[0032] With the above structure, specifically in the process of measuring, checking and controlling the spacing of steel bars, since the spacing control component 2 is installed between the two sides of the U-shaped support 1, after adjusting the two moving seats 202 of the spacing control component 2 to have the same spacing as the construction requirements when bundling steel bars and locking them, by placing and comparing the two moving seats 202 on the upper sides of the adjacent steel bars on both sides through the limiting grooves 204 respectively, it is possible to visually measure and check whether the spacing of the adjacent steel bars on both sides meets the construction requirements. At the same time, by clamping the adjacent steel bars on both sides through the limiting grooves 204 at both positions respectively, the spacing of the adjacent steel bars on both sides can be corrected and controlled to meet the construction requirements. The method of measuring, checking and controlling the spacing of the adjacent steel bars on both sides is simple and easy to implement, replacing the manual measurement method relying on a tape measure, which is beneficial to reducing the workload of workers. Specifically, when adjusting the distance between the two moving seats 202, by sliding the moving seat 202 along the screw 201 through the mating hole 207 and pressing the limiting nuts 203 at both positions on the surface of the moving seat 202, the distance between the two moving seats 202 can be adjusted and locked. The method of adjusting the distance between the two moving seats 202 is simple and easy to operate, and then it is convenient to adjust the two moving seats 202 to have the same spacing as the construction requirements when bundling steel bars. At the same time, in the process of adjusting the distance between the two moving seats 202, by referring to the reference rod 2010 and comparing it with the scale 208, the distance between the two moving seats 202 can be visually quantitatively controlled, which further facilitates adjusting the two moving seats 202 to have the same spacing as the construction requirements when bundling steel bars. It is convenient to use the spacing control component 2 at the construction site to measure and control the spacing of the adjacent steel bars on both sides. And since the distance between the two moving seats 202 is adjustable, the spacing control component 2 can have good applicability, and further it is convenient to use the spacing control component 2 at the construction site to measure and control the spacing of the adjacent steel bars on both sides.
