Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and discloses a tensile testing device for construction engineering. Background Technique

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. Among them, "housing building" refers to a project with a roof, beams, columns, walls, foundation and the ability to form an internal space to meet the needs of people's production, residence, study and public activities. Since it is necessary to detect the tensile force of construction materials such as plates and steel bars in construction engineering, a tensile testing device is required during the detection of steel bars.

[0003] The patent with the patent number CN218546386U in the prior art discloses a tensile testing device for construction engineering detection, including a base. Both sides of the top of the base are fixedly installed with support plates. A top plate is installed above the two support plates, and both ends of the top plate are fixedly connected to the inner walls of the two support plates respectively. A second steel bar clamp is fixedly installed in the middle of the top of the base. A lifting plate is installed below the top plate. A high-precision distance sensor is fixedly installed on the top of the lifting plate, and a tensile force sensor is fixedly installed in the middle of the bottom of the lifting plate. In the utility model, during the pulling process of the steel bar, when the tensile force sensor feeds back the tensile force value to the controller, the controller will start the electric push rod to drive the cross bar to lift, so as to lift the nylon cloth for protection, thus effectively avoiding the situation that debris splashes to the outside and causes harm to the staff, and achieving a good protection effect.

[0004] However, the patents in the prior art have the following several disadvantages:

[0005] (1) The height of the hydraulic cylinder cannot be adjusted, so it is not convenient to fix steel bars of different lengths, resulting in the inability to perform detection.

[0006] (2) Using an electric push rod to drive the nylon cloth to rise, the rising height is limited and full-range protection cannot be achieved. Content of the Utility Model

[0007] The purpose of the utility model is to provide a tensile testing device for construction engineering, which solves the problems that the prior art cannot be applied to steel bars of different lengths and the protection effect is not ideal by setting a liftable hydraulic cylinder and a protection component.

[0008] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0032] Please refer to Figures 1-5 , a tensile testing device for construction engineering, including a base 1. There are universal wheels 101 at the four corners of the bottom end of the base 1, which facilitate the movement of the device. There is a controller 102 on the front surface of the base 1 for controlling the operation of the device. There are first magnet bars 103 on both the front and rear sides of the upper surface of the base 1. There are vertical plates 2 on both the left and right sides of the upper end of the base 1. There is a top plate 201 between the two vertical plates 2, which can prevent debris from flying out from above. Both the left and right ends of the top plate 201 are fixedly connected to the vertical plates 2. There are chutes 202 on the surfaces of the mutually approaching ends of the two vertical plates 2. There is a lifting plate 3 below the top plate 201. There are sliding rods 301 at both the left and right ends of the lifting plate 3. The mutually remote ends of the two sliding rods 301 are respectively slidably connected to the chutes 202. The lifting plate 3 can move in the vertical direction along the chutes 202. There is a hydraulic cylinder 302 at the bottom end of the lifting plate 3. There is a tensile force sensor 303 at the bottom end of the hydraulic cylinder 302, which can record the tensile force. There are reinforcing bar chucks 304 at both the bottom end of the tensile force sensor 303 and the upper end of the base 1. The two reinforcing bar chucks 304 can fix the upper and lower ends of the reinforcing bar. Place the reinforcing bar between the two reinforcing bar chucks 304 and start the hydraulic cylinder 302 to pull the reinforcing bar upward, then the tensile test of the reinforcing bar can be carried out. There is a protection component 4 at the upper end of the top plate 201, which can prevent debris from bursting out.

[0033] Specifically, there are a screw rod 203 and a guide rod 204 respectively inside the two chutes 202. The upper and lower ends of the screw rod 203 are respectively rotatably connected to the vertical plates 2. The upper end of the screw rod 203 is connected to a first motor 205, which can control the rotation of the screw rod 203. The left and right sliding rods 301 are respectively sleeved on the screw rod 203 and the guide rod 204. The sliding rod 301 will move in the vertical direction as the screw rod 203 rotates. The guide rod 204 can keep the movement of the lifting plate 3 stable.

[0034] Through the above technical solution, the first motor 205 can drive the screw rod 203 to rotate, and then make the lifting plate 3 move in the vertical direction to adjust the height of the hydraulic cylinder 302 so as to adapt to reinforcing bars of different lengths.

[0035] Specifically, the protection component 4 includes winding rollers 401. There are two winding rollers 401. A nylon cloth 406 is wound around the surface of the winding rollers 401. The nylon cloth 406 can block the splashing debris. Both the left and right ends of the winding rollers 401 are rotatably connected to fixing plates 402. The bottom ends of the fixing plates 402 are fixedly connected to vertical plates 2, which can fix the winding rollers 401. At the right ends of the front and rear winding rollers 401, there are a first gear 403 and a second gear 404 respectively. The first gear 403 meshes with the second gear 404. The first gear 403 can drive the second gear 404 to rotate. There is a second motor 405 on the left side of the second gear 404. The second motor 405 is fixedly connected to the fixing plate 402. The right end of the second motor 405 is fixedly connected to the winding roller 401. The second motor 405 can control the rotation of the rear winding roller 401. There is a second magnet strip 407 at the bottom end of the nylon cloth 406. The second magnet strip 407 corresponds to the first magnet strip 103 one by one.

[0036] Through the above technical solution, when the second motor 405 is started, the second motor 405 can drive the two winding rollers 401 to rotate in opposite directions simultaneously through the first gear 403 and the second gear 404, and release the nylon cloth 406. After the second magnet strip 407 at the bottom end of the nylon cloth 406 is adsorbed on the first magnet strip 103, the nylon cloth 406 can fully cover the steel bar, achieving a better protection effect.

[0037] During use, first, the controller 102 is used to control the first motor 205 to drive the screw 203 to rotate, so that the lifting plate 3 moves in the vertical direction, adjusting the height of the hydraulic cylinder 302. The steel bar is placed between the two steel bar chucks 304. Subsequently, the second motor 405 is started. The second motor 405 drives the two winding rollers 401 to rotate in opposite directions simultaneously through the first gear 403 and the second gear 404, and releases the nylon cloth 406. After the second magnet strip 407 at the bottom end of the nylon cloth 406 is adsorbed on the first magnet strip 103, the nylon cloth 406 can fully cover the steel bar. Finally, the hydraulic cylinder 302 is started to pull the steel bar upward, and the tensile test of the steel bar can be carried out.
