Description

Technical Field

[0001] This application relates to the field of steel bar testing equipment, and in particular to a device for detecting the bending of building steel bars. Background Technology

[0002] As we all know, steel bars are steel strips and a type of building material. In reinforced concrete, they are used to support the framework of the structure. Steel bars are tensile but not compressive, while concrete is compressive but not tensile. The combination of the two results in good mechanical strength. The steel bars are protected by the concrete and do not rust, making them a widely used material in reinforced concrete buildings. Before arriving at the construction site, steel bars often need to be tested for their bending degree.

[0003] Currently, in related technologies, a search reveals that utility model patent publication number CN220626058U discloses a rebar bending device for testing building steel structures, belonging to the technical field of rebar testing equipment. It includes a platform, a bending force-applying component, a swing arm assembly, and a screw adjuster. A first and second enclosure plate are fixed to the front and rear sides of the top of the platform; a side seat is fixed to one end of the first and second enclosure plates on the top of the platform; the bending force-applying component includes a turntable with multiple through holes, one of which movably embeds a force-bearing column.

[0004] While the aforementioned technologies can improve the bending safety and stability of reinforcing bars, the applicant has found the following drawbacks: the device may be designed primarily for reinforcing bars within a specific specification range, and it is less adaptable to reinforcing bars that are too large or too small, thus limiting its practicality.

[0005] Therefore, we propose a device for detecting the bending of building steel bars. Utility Model Content

[0006] The purpose of this invention is to provide a device for detecting the bending of reinforcing steel bars in buildings, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0009] Base;

[0010] The mounting bracket is detachably connected to the base, and has two mounting holes, with threaded rings fixedly connected in the mounting holes.

[0011] Two threaded rods are threadedly screwed onto a threaded ring. One end of the threaded rod located inside the mounting bracket is rotatably connected to a positioning clamp, and the positioning clamp is vertically slidably connected to the mounting bracket via a connecting assembly.

[0013] Two electro-hydraulic push cylinders are fixedly connected to the base, and the output shaft of their electro-hydraulic push rods is fixedly connected to an L-shaped plate.

[0014] A support assembly disposed within a base for supporting the base in its place of use.

[0015] As a further improvement of this utility model: the support assembly includes four support columns, all of which are disposed in the base through connecting grooves, and the other end of each support column is fixedly connected to a support seat.

[0016] As a further improvement of this utility model, the bottom of each of the multiple support seats is fixedly connected with an anti-slip rubber pad.

[0017] As a further improvement of this utility model: the connecting component includes two T-shaped blocks, which are correspondingly disposed on the outer wall of the positioning clamp, and the T-shaped blocks are vertically slidably connected to the mounting bracket through T-shaped grooves.

[0018] As a further improvement of this utility model, a turntable is fixedly connected to both of the threaded rods.

[0019] As a further improvement of this utility model, rubber pads are provided inside both the positioning clamp and the L-shaped plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By setting up a support assembly, with the cooperation of multiple support columns and support seats, the base is placed in the usage position. Then, the rebar to be bent and tested is placed into the mounting frame. Then, by setting up a connecting assembly and rotating the threaded rod, the positioning clamp is vertically displaced by the cooperation of the T-block, T-slot, threaded rod and threaded ring, so that the positioning clamp is tightly fitted with the rebar in the mounting frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-4 In this embodiment of the utility model, a device for detecting the bending of building steel bars includes:

[0030] Base 1;

[0031] Mounting bracket 2 is detachably connected to base 1. Two mounting holes are provided in the mounting bracket 2, and threaded rings 3 are fixedly connected in the mounting holes.

[0032] Two threaded rods 4 are threaded together with threaded rings 3. One end of the threaded rod 4 located inside the mounting bracket 2 is rotatably connected to a positioning clip 5, and the positioning clip 5 is vertically slidably connected to the mounting bracket 2 through a connecting assembly.

[0033] Rubber pad 6 is fixedly connected to the base 1 through a groove;

[0034] Two electro-hydraulic push cylinders 7 are fixedly connected to the base 1, and the output shaft of their electro-hydraulic push rods is fixedly connected to an L-shaped plate 8.

[0035] A support assembly is disposed within the base 1 and is used to support the base 1 in its place of use.

[0036] In use, the rebar bending detection device can be configured with a support assembly. Under the action of the support assembly, the base 1 is placed in the working position, and then the rebar to be bent is placed into the mounting frame 2. By setting up a connecting assembly and rotating the threaded rod 4, the positioning clamp 5 is vertically displaced by the cooperation of the T-block 12, the T-slot, the threaded rod 4, and the threaded ring 3. This allows the positioning clamp 5 to fit tightly against the rebar in the mounting frame 2. Then, by activating two electro-hydraulic push cylinders 7, the cooperation of the electro-hydraulic push cylinders 7 and the L-shaped plate 8 performs the function of bending detection on the rebar after it has been limited.

[0037] exist Figure 1-3 The support assembly includes four support columns 9, which are all set in the base 1 through connecting grooves. The other end of each support column 9 is fixedly connected to a support seat 10, and the bottom of each support seat 10 is fixedly connected to an anti-slip pad 11.

[0038] The steel bar bending detection device for buildings, through the arrangement of this structure, with the cooperation of multiple support columns 9 and support bases 10, makes it easy to place the base 1 in the use position, and with the cooperation of multiple anti-slip rubber pads 11, the friction between the support base 10 and the ground is increased, preventing the base 1 from slipping during use.

[0039] exist Figure 1-4 In the middle: the connecting component includes two T-shaped blocks 12, which are respectively set on the outer wall of the positioning clamp 5. The T-shaped blocks 12 are vertically slidably connected to the mounting bracket 2 through the T-shaped groove. A turntable 13 is fixedly connected to each of the two threaded rods 4 to facilitate the movement of the threaded rods 4. Rubber pads 14 are provided in the positioning clamp 5 and the L-shaped plate 8 to increase the friction between the positioning clamp 5 and the L-shaped plate 8 and the reinforcing bar.

[0040] In this embodiment, the electro-hydraulic pusher cylinder 7 is a commercially available device known to those skilled in the art. It can be customized or selected according to actual needs. Here, we are only using it without making any structural or functional improvements. We will not go into details here. The electro-hydraulic pusher cylinder 7 is equipped with a matching control switch. The installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0041] The implementation principle of the building rebar bending detection device in this application embodiment is as follows: First, the base 1 is placed in the use position by the mutual cooperation of multiple support columns 9 and support seats 10. Then, the user puts the rebar to be bent into the mounting frame 2. At the same time, by rotating the turntable 13, the threaded rod 4 is driven to rotate. Then, with the mutual cooperation of the T-shaped block 12 and the T-shaped groove, the positioning clamp 5 is vertically displaced, so that the positioning clamp 5 is tightly attached to the rebar in the mounting frame 2. Then, by activating two electro-hydraulic push cylinders 7, the bending detection of the rebar after the limit is achieved through the mutual cooperation of the electro-hydraulic push cylinders 7 and the L-shaped plate 8.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
