Description

Technical Field

[0001] This utility model relates to the field of building inspection technology, and more specifically, to a device for assessing and testing the load-bearing capacity of a building's main structure. Background Technology

[0002] The core area of ​​beams and columns is a crucial load-bearing region of the building structure. The concrete grade in this area is consistent with that of the columns, but the beam grade is lower than or equal to the column grade. During concrete pouring, due to insufficient interception, lower-grade concrete may be poured into the core area, i.e., the column head. Therefore, strength testing of the column head is essential. Currently, testing the column head requires standing on a ladder or fixing a rebound hammer to a support. Existing supports cannot adjust the testing angle, and the strength of the floor slab cannot be tested after testing the column head. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a testing device for assessing the load-bearing capacity of a building's main structure, which can change the testing angle of the rebound hammer.

[0007] Furthermore, the length of the sliding frame is greater than the length of the retractable end of the rebound spring.

[0008] Furthermore, the steering mechanism also includes a hinge located at the bottom of the connecting plate, and one end of the fixing rod is fixedly connected to the hinge.

[0009] Furthermore, the side wall of the fixing rod is provided with a first threaded hole, and a second bolt is screwed onto the connecting plate. When the first threaded hole is in contact with the connecting plate, the second bolt can be screwed into the first threaded hole.

[0010] Furthermore, the side wall of the fixing rod is provided with a first connecting hole, which passes through the fixing rod. A reinforcing rod is rotatably connected to the bottom of the connecting plate. The reinforcing rod is provided with a second connecting hole. When the first connecting hole and the second connecting hole are fitted together, a positioning pin can be inserted into the first connecting hole and the second connecting hole.

[0011] Furthermore, the telescopic assembly consists of multiple telescopic rods connected together, with a third bolt at the top of the uppermost telescopic rod and a second threaded hole at the bottom of the fixing rod, the third bolt being screwed into the second threaded hole.

[0012] Furthermore, the top of the telescopic rod has a handle on its side wall.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] like Figure 1 , Figure 2 As shown, a testing device for assessing the load-bearing capacity of a building's main structure includes a rebound hammer 1, and further includes: a support frame 2 detachably connected to the rebound hammer 1; a pusher mechanism 3 for driving the support frame 2 to slide, the lower part of the pusher mechanism 3 being a connecting plate 31; a steering mechanism 4 rotatably connected to the bottom of the connecting plate 31, the steering mechanism 4 including a fixed rod 41; a telescopic component 5 disposed below the fixed rod 41; and a foot pedal 6 disposed at the bottom of the telescopic component 5.

[0023] The upper part of the support frame 2 has a groove for placing the rebound hammer 1. The groove is arc-shaped, and its shape is the same as the curvature of the handle end of the rebound hammer 1. Two first bolts 11 are welded to the tail of the rebound hammer 1. The first bolts 11 can pass through the side wall of the tail of the support frame 2, and a positioning nut is provided on the first bolt 11. When performing high-level column head strength testing, the rebound hammer 1 is slid into the groove, so that the first bolts 11 pass through the support frame 2. Then, the positioning nut is screwed in so that the positioning nut is pressed against the rear wall of the support frame 2, thereby fixing the rebound hammer 1 to the support frame 2.

[0024] The booster mechanism 3 drives the support frame 2 to move, thereby causing the rebound hammer 1 probe to retract and rebound to complete the detection. The booster mechanism 3 also includes: a sliding frame 32 located on the side wall of the support frame 2, the sliding frame 32 being fixed to the connecting plate 31, the sliding frame 32 restricting the support frame 2 to move only back and forth, so that the rebound hammer 1 makes perpendicular contact with the detection point, and the measured data is accurate; a motor 33 fixed to the tail of the sliding frame 32, the motor 33 being fixedly connected to the connecting plate 31, the motor 33 being started and stopped by a remote control or wired connection controller; and a threaded rod 34 fixed to the output end of the motor 33, the motor 33 driving the threaded rod 34 to rotate, the threaded rod 34 being screwed to the bottom of the support frame 2. When the motor 33 starts, the threaded rod 34 rotates, thereby driving the support frame 2 to move back and forth along the sliding frame 32, so that the rebound hammer 1 contacts the wall to complete the rebound detection.

[0025] The length of the sliding frame 32 is greater than the length of the retracted end of the rebounder 1. When the support frame 2 is at the last end of the sliding frame 32, the front end of the rebounder 1 is located behind the front end of the sliding frame 32.

[0026] When testing the strength of column heads or wall heads, the connecting plate 31 is perpendicular to the fixing rod 41. When testing the strength of beam bottoms or floor slabs, the connecting plate 31 and the fixing rod 41 need to be horizontal. The steering mechanism 4 also includes a hinge 42 located at the bottom of the connecting plate 31. One end of the fixing rod 41 is fixedly connected to the hinge 42. The fixing rod 41 changes its positional relationship with the connecting plate 31 by rotating through the hinge 42. When the fixing rod 41 is parallel to the connecting plate 31, the side wall of the fixing rod 41 is in contact with the connecting plate 31.

[0027] The side wall of the fixing rod 41 is provided with a first threaded hole 411, and a second bolt 311 is screwed onto the connecting plate 31. When the first threaded hole 411 is in contact with the connecting plate 31, the first threaded hole 411 is located directly below the second thread. The second bolt 311 can be screwed into the first threaded hole 411. After the second bolt 311 connects the connecting plate 31 and the fixing rod 41, the rebound device 1 can maintain a vertically upward posture.

[0028] The side wall of the fixed rod 41 is provided with a first connecting hole 414, which passes through the fixed rod 41. The bottom rear end of the connecting plate 31 is rotatably connected to a reinforcing rod 312. When there is no external force, the reinforcing rod 312 is in a vertically downward free state. The free end of the reinforcing rod 312 is provided with a second connecting hole 3121. When the connecting plate 31 is perpendicular to the fixed rod 41, the reinforcing rod 312 can be rotated to make the first connecting hole 414 fit with the second connecting hole 3121. The first connecting hole 414 and the second connecting hole 3121 can be inserted into the positioning pin 412. After the positioning pin 412 is inserted, the movement of the free end of the reinforcing rod 312 is restricted. At this time, the reinforcing rod 312, the fixed rod 41 and the connecting plate 31 form a triangular structure, so that the support frame 2 and the rebound device 1 are stably kept perpendicular to the fixed rod 41.

[0029] The telescopic assembly 5 is used to bring the rebound spring 1 to the height of the column head. The telescopic assembly 5 consists of multiple telescopic rods connected together, and the telescopic rods' extension, retraction, and fixing methods adopt existing technology. For example... Figure 3 As shown, the top of the uppermost telescopic rod is provided with a third bolt 413, and the bottom of the fixed rod 41 is provided with a second threaded hole 51. When it is necessary to raise the height of the rebounder 1, the third bolt 413 is screwed into the second threaded hole 51. At this time, the height of the rebounder 1 can be changed by stretching the telescopic component 5.

[0030] The top telescopic rod has a handle 52 on its side wall, which can be pulled to operate when it is extended or retracted.

[0031] The foot pedal 6 and the handle 52 are on the same side, and the foot pedal 6 is in contact with the floor. During the rebound, the device is fixed in position by stepping on the foot pedal 6 and holding the handle 52. Then, the motor 33 is started to push the support frame 2 and the rebound device 1 towards the detection point. When the rebound device 1 rebounds and generates a reaction force, the handle 52 is gripped tightly and the foot pedal 6 is pressed firmly so that the device can cope with the reaction force.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
