[0002] When conducting building monitoring, the connection points of structural members are usually inspected. This is usually done by applying vertical or horizontal force to the exposed steel bars to simulate the loads that occur in actual use, and measuring relevant parameters such as displacement and strain. This is used to determine whether the connection between the anchor rod and the foundation is firm, and then evaluate the safety status of the building structure.

[0003] Existing building structure connection point strength testing instruments are mostly used by placing a hollow cylinder on the outside of the steel bar and fixing it with a clip to apply force by pulling. However, in many cases, the exposed part of the steel bar is not perpendicular to the wall during use. Therefore, it is not only difficult to install and set the structure, but also affects the test results to a certain extent, making it inconvenient to use.

Therefore, it is not only difficult to install and sleeve the structure, but also affects the test results to a certain extent, making it inconvenient to use.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , this utility model provides a technical solution:

[0028] An instrument for testing the strength of connection points of building structural members with good stability comprises a manual pump 1, an unloading valve 2 is installed on the inner side of the manual pump 1, a pressure gauge 3 is installed on the right side of the manual pump 1, a hollow oil cylinder 4 is installed on the right side of the manual pump 1 through a pressure measuring oil pipe, an anchor plate 5 is provided on the right side of the hollow oil cylinder 4, a correction component 8 is provided on the left side of the anchor plate 5, and a fastening component 9 is provided on the outer side of the correction component 8;

[0029] The correction assembly 8 includes two groups of sleeves 801, and a hollow frame 802 is bolted between the two groups of sleeves 801. The inner side of the hollow frame 802 is rotatably connected to a rotating shaft 803, the outer side of the rotating shaft 803 is rotatably connected to a correction rod 804, and the inner side of the correction rod 804 is rotatably connected to a correction wheel 805.

[0030] In this embodiment: by setting a manual pump 1 in conjunction with the unloading valve 2, the pressure gauge 3 and the hollow cylinder 4, normal detection of the strength of the connection points of steel bar building structures can be carried out, and the anchor plate 5 is used as an anchor point for the detection position and is also used as a support for the structure. When in use, the anchor plate 5 can be first sleeved on the outside of the steel bar through a preset hole. If the steel bar is relatively tilted or bent, the hollow cylinder 4 can be omitted. The sleeve 801 of the correction component 8 can be sleeved on the outside of the steel bar first, and then the correction rod 804 is rotated along the rotating shaft 803, and the steel bar is continuously applied with the correction wheel 805. While applying force, the correction wheels 805 on the inside of the two sets of sleeves 801 will straighten the steel bar during the horizontal movement of the correction component 8, so that the steel bar is deformed relatively flat, so as to facilitate the sleeve of the hollow cylinder 4 for processing.

[0031] Specifically, such as Figure 1 、 Figure 4 As shown, the fastening assembly 9 includes a tapered sleeve 901 , which is used in conjunction with the correction rod 804 .

[0032] Specifically, such as Figure 4 As shown, a side bracket 902 is bolted to the outer side of the right side of the sleeve 801 , and an electric cylinder 903 is bolted to the right side of the side bracket 902 . The telescopic end of the electric cylinder 903 passes through the side bracket 902 and cooperates with the tapered sleeve 901 .

[0033] Specifically, such as Figure 4 As shown, the telescopic end of the electric cylinder 903 is bolted to a fixing frame 904 , and the inner side of the fixing frame 904 is bolted to two conical sleeves 901 respectively.

[0034] In this embodiment: by providing a fastening assembly 9, when the sleeve 801 is sleeved on the outside of the steel bar, the telescopic end of the electric cylinder 903 on the right side of the side bracket 902 is extended to displace through the fixing frame 904 and the conical sleeve 901 connected thereto. At this time, the inclined surface of the conical sleeve 901 and the correction rod 804 are in contact and pressed against each other, causing it to rotate along the rotating shaft 803, which can reduce manpower consumption and enable multiple correction rods 804 to apply force to the steel bar for correction at the same time.

[0035] Specifically, such as Figure 3 As shown, a torsion spring 10 is bolted to the outer side of the correction rod 804 , and the torsion spring 10 is bolted to the sleeve 801 on the side close to the sleeve 801 .

[0036] Specifically, such as Figure 5As shown, widened plates 11 are provided at the top and bottom of the right side of the anchor plate 5 , and anti-slip grooves are provided on the outer side of the widened plates 11 .

[0037] In this embodiment: by setting a torsion spring 10, when the correction rod 804 tilts, deformation and force storage will occur, and when the force on the correction rod 804 stops, the driving structure will reset. The widened plate 11 set can increase the contact area with the building structure to avoid damage to the plane of the building structure.

[0038] Specifically, such as Figure 2 As shown, the bottom of the right sleeve 801 is bolted with a vertical frame 12, the left side of the anchor plate 5 is bolted with a guide rail 13, the inner side of the guide rail 13 is slidably connected with a slider 14, and the top of the slider 14 is bolted to the vertical frame 12.

[0039] Specifically, such as Figure 2 As shown, the inner side of the guide rail 13 is rotatably connected to the screw rod 6 , and the outer side of the screw rod 6 is threadedly connected to the slider 14 .

[0040] Specifically, such as Figure 2 As shown, the control motor 7 is bolted to the left side of the guide rail 13 , and the output end of the control motor 7 passes through the guide rail 13 and is bolted to the lead screw 6 .

[0041] Specifically, such as Figure 1 As shown, a reaction force support ring is provided on the right side of the hollow cylinder 4, and an anchor ring and a clip are installed on the left side of the hollow cylinder 4.

[0042] In this embodiment: by setting a guide rail 13 to cooperate with the slider 14, when the control motor 7 drives the screw rod 6 to rotate, the slider 14 threadedly connected thereto will move horizontally along the guide rail 13. At this time, the sleeve 801 connected to the slider 14 through the vertical frame 12 will also move together, thereby achieving the effect of horizontally moving the correction component 8. Not only does it not require manpower to repeatedly move the correction component 8, it can also ensure that the structure always remains horizontal for correction.

[0043] Working principle: When inspecting the connection points of the building structure, the anchor plate 5 is first sleeved on the outside of the steel bar through the preset hole. If the steel bar is relatively tilted or bent, the hollow cylinder 4 can be installed first. The sleeve 801 of the correction component 8 is first sleeved on the outside of the steel bar, and then the correction rod 804 is rotated along the rotating shaft 803, and the steel bar is continuously applied with the correction wheel 805. While applying force, the correction wheel 805 on the inside of the two sets of sleeves 801 will straighten the steel bar in the process of horizontally moving the correction component 8, so that the steel bar is deformed relatively flat, so as to facilitate the sleeve of the hollow cylinder 4 for processing. When the fastening component 9 sleeves the sleeve 801 on the outside of the steel bar, the telescopic end of the electric cylinder 903 on the right side of the side bracket 902 extends to displace through the fixing frame 904 and the conical sleeve 901 connected thereto. At this time, the inclined surface of the conical sleeve 901 and the correction rod 804 are in contact and pressed.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
