Through these functions, pull-out bar testing provides key assurance for the safety, reliability, and durability of building structures.

[0003] In the prior art, such as the Chinese announcement number CN208780557U, a pull-out force device for engineering quality inspection includes a conical nut; the top cylinder is a cylindrical structure with internal threads, connected to the bottom side of the spiral end by threads; there are three columns, which are cylindrical shafts, distributed in a ring array and welded to the bottom side of the top cylinder; the scale is set on the three columns; the ring block is a circular plate structure with a conical hole, and is welded to the bottom between the columns through the three circular array connecting ribs; the concentric block is a disc structure with a circular through hole in the middle and a disc thread on the top side, and is welded to the middle between the columns through the three circular array connecting ribs. This utility model has a simple structure, is easy to manufacture, has low cost, is easy to operate, the embedment depth is relatively intuitive, it is easy to collect experimental data, it can quickly fix the steel bars, is easy to disassemble and maintain, and can be widely used in steel bar pull-out experiments in laboratories or construction sites.

[0004] The aforementioned application achieves convenient disassembly and maintenance through a multi-component structure. However, the device lacks two clamping and fixing methods and is not easy to stably clamp steel bars of different sizes, which to some extent reduces the overall convenience and timeliness. Utility Model Content

[0005] This invention improves the stability of the device during testing by clamping it in two ways, and makes the pressure block rotate automatically inward and towards the reinforcing bar, thereby improving the clamping effect of the pressure block and the adaptability of the device, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a pull-out bar tensioning device for engineering quality inspection, comprising a mounting block, a through groove inside the mounting block, a threaded post threaded to the side of the mounting block, a knob fixedly connected to the outer side of the threaded post, a clamping block fixedly connected to the rotation of the threaded post, a side plate fixedly connected to one side of the mounting block, a through hole on the surface of the side plate, a mounting plate fixedly connected to the surface of the side plate, a rotating shaft rotatably connected inside the mounting plate, a pressure block rotatably mounted on the surface of the rotating shaft, a buckle fixedly connected to the outer side of the mounting plate, a rope passing through the inside of the buckle, the middle part of the rope passing through the inside of the lifting ring, and a tension gauge fixedly connected to the inner side of the lifting ring. Through the arrangement of the above components, the device can stably clamp building reinforcing bars and can easily clamp reinforcing bars of different sizes, improving the stability and adaptability of the device.

[0007] Preferably, a gasket is fixedly connected to the inner side of the clamping block, and the inner sides of the clamping block and the gasket are V-shaped. The shape of the clamping block and the gasket facilitates their fixing to the sides of steel bars of different sizes.

[0008] Preferably, the side of the pressure block is connected with several anti-slip strips at equal intervals, and a connecting plate is fixedly connected to one side of the pressure block. The anti-slip strips improve the friction and stability of the pressure block during use, and the connecting plate facilitates the control of the angle of the pressure block.

[0009] Preferably, one side of the pressure block is teardrop-shaped, and the arc surface of the pressure block is close to the through hole. The shape of the pressure block facilitates the automatic pressing of the surface of the reinforcing bar.

[0010] Preferably, the size of the clamping block matches the size of the through groove, and the side of the clamping block is slidably connected to the inner wall of the through groove. The connection method between the clamping block and the through groove facilitates the device to limit the clamping block and improves the stability of the clamping block during operation.

[0011] Preferably, two clamping blocks are provided, and the clamping blocks are distributed on both sides of the through hole. By setting the number and distribution of the clamping blocks, it is easy for the clamping blocks to stably clamp the reinforcing bars.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the threaded column is rotated inside the mounting block by rotating the knob, and the clamping block slides on the inner wall of the through groove. After the shim fixedly connected to the inner side of the clamping block clamps the surface of the reinforcing bar, the connecting plate is pushed outward to make the pressure block rotate on the surface of the rotating shaft. The pressure block with a teardrop shape on one side presses the surface of the reinforcing bar. By clamping the device in two ways, the stability of the device during testing is improved.

[0014] 2. In this utility model, the shape of the clamping block and the shim facilitates the clamping block and the shim to be fixed on the side of steel bars of different sizes. When the device is pulled outward, the anti-slip strip is subjected to friction, causing the pressure block to rotate inward and towards the steel bar, which further improves the clamping effect of the pressure block and improves the adaptability of the device.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1-4This utility model provides a technical solution: a pull-out bar tensioning device for engineering quality inspection, including a mounting block 1, a through groove 2 inside the mounting block 1, a threaded post 4 threadedly fitted on the side of the mounting block 1, a knob 3 fixedly connected to the outside of the threaded post 4, a clamping block 5 fixedly connected to the rotation of the threaded post 4, a side plate 7 fixedly connected to one side of the mounting block 1, a through hole 8 on the surface of the side plate 7, a mounting plate 9 fixedly connected to the surface of the side plate 7, a rotating shaft 10 rotatably connected inside the mounting plate 9, a pressure block 11 rotatably mounted on the surface of the rotating shaft 10, a buckle 14 fixedly connected to the outside of the mounting plate 9, a rope 15 passing through the inside of the buckle 14, the middle part of the rope 15 passing through the inside of the lifting ring 16, and a tension gauge 17 fixedly connected to the inside of the lifting ring 16. Through the above-mentioned component arrangement, the device can stably clamp the building reinforcement bars and can easily clamp reinforcement bars of different sizes, improving the stability and adaptability of the device.

[0023] like Figure 2 As shown, a gasket 6 is fixedly connected to the inner side of the clamping block 5. The inner sides of the clamping block 5 and the gasket 6 are V-shaped. The shapes of the clamping block 5 and the gasket 6 facilitate the fixing of the clamping block 5 and the gasket 6 to the sides of steel bars of different sizes.

[0024] like Figure 3 As shown, several anti-slip strips 12 are connected at equal intervals on the side of the pressure block 11, and a connecting plate 13 is fixedly connected to one side of the pressure block 11. The anti-slip strips 12 improve the friction and stability of the pressure block 11 during use, and the connecting plate 13 facilitates the control of the angle of the pressure block 11.

[0025] like Figure 3 As shown, one side of the pressure block 11 is teardrop-shaped, and the arc surface of the pressure block 11 is close to the through hole 8. The shape of the pressure block 11 facilitates the automatic pressing of the surface of the reinforcing bar by the pressure block 11.

[0026] like Figure 2 As shown, the size of the clamping block 5 matches the size of the through groove 2. The side of the clamping block 5 is slidably connected to the inner wall of the through groove 2. Through the connection method between the clamping block 5 and the through groove 2, the device can effectively limit the clamping block 5 and improve the stability of the clamping block 5 during operation.

[0027] like Figure 2 As shown, two clamping blocks 5 are set, and the clamping blocks 5 are distributed on both sides of the through hole 8. The number and distribution of the clamping blocks 5 make it easy for the clamping blocks 5 to stably clamp the steel bars.

[0028] The usage and working principle of this device are as follows: First, place the mounting block 1 on the surface of the building steel bar, so that the steel bar passes through the inside of the through hole 8. At this time, rotate the knob 3 to make the threaded column 4 rotate inside the mounting block 1, and the clamping block 5 slides on the inner wall of the through groove 2. After the pad 6 fixedly connected to the inner side of the clamping block 5 clamps the surface of the steel bar, push the connecting plate 13 outward to make the pressure block 11 rotate on the surface of the rotating shaft 10. The pressure block 11, which is teardrop-shaped on one side, presses the surface of the steel bar. The steel bar is tested by pulling the lifting ring 16, and the tension gauge 17 displays the measurement result.

[0029] Based on this, the inner shape of the clamping block 5 and the shim 6 is V-shaped. The shape of the clamping block 5 and the shim 6 makes it easy for the clamping block 5 and the shim 6 to be fixed on the side of steel bars of different sizes. When the device is pulled outward, the anti-slip strip 12 is subjected to friction, which causes the pressure block 11 to rotate inward and towards the steel bar, further improving the clamping effect of the pressure block 11.

[0030] The force gauge 17 used in this application is the Jipin Times Mark-10 Series7, which are common and conventional devices on the market and are well known to those skilled in the art. In this application, the above-mentioned devices are used in a conventional manner without any modification to their structure or function. As for their settings, installation and electrical connection methods, those skilled in the art can perform debugging operations according to the corresponding product instruction manuals, so they will not be described in detail here.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
