Technical Field

[0001] The utility model relates to the technical field of detection equipment, and particularly relates to a load test detection device for building structures. Background Art

[0002] The load test detection device for building structures is a tool used to evaluate the performance and safety of building structures when subjected to external loads. They can simulate the loads received by the building, detect parameters such as the deformation and stress of the building structure, and check the changes in parameters such as the appearance quality, dimensions, and deformation of the building structure after the detection to determine whether the building structure meets the building standards.

[0003] When detecting a building structure, pressure needs to be applied to it. Building structures generally use steel bars and concrete materials. When the building structure reaches its maximum bearing pressure, cracking and deformation will occur, and at the same time, the sand and gravel inside the concrete will fly outwards. The flying sand and gravel may hit the detection personnel and cause injury to the detection personnel. To solve this technical problem, the utility model proposes a load test detection device for building structures. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a load test detection device for building structures, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

One side of the guard plate is connected to the upper surface of the support base, the baffle is hingedly connected to the guard plate, a first hydraulic cylinder is arranged outside the guard plate, a gantry is connected to the upper surface of the support base, a second hydraulic cylinder is arranged below the gantry, a pressure sensor is installed at the output end of the second hydraulic cylinder, a pressure head is detachably connected below the pressure sensor, and a detection table is connected to the upper surface of the support base and is located below the pressure head.

[0007] Preferably, two support frames are connected to the upper surface of the support base, and the two support frames are symmetrical to each other and are located outside the detection table at the same time.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1-5 shown, a load test and detection device for a building structure includes a support base 1, a guard plate 2 and a baffle 3. The appearance of the guard plate 2 is in a concave shape with one side open. The concave-shaped guard plate 2 forms a three-sided shield, and the open side forms a passage for conveniently placing the building structure. One side of the guard plate 2 is connected to the upper surface of the support base 1. The baffle 3 is hinged to the guard plate 2, and the open side is hinged to the baffle 3. When it is necessary to put the building structure into the test bench 9, the baffle 3 is pushed to swing upward. After the building structure is placed, the baffle 3 is pulled to swing downward to form a shield for the open side of the guard plate 2. A positioning block 17 is connected to one side of the guard plate 2, and a positioning groove 18 adapted to the positioning block 17 is opened inside the baffle 3. After the first hydraulic cylinder 4 pulls the baffle 3 into contact with the guard plate 2, at the same time, the positioning block 17 enters the inside of the positioning groove 18. The contact between the positioning block 17 and the positioning groove 18 can improve the stability of the baffle 3.

[0023] A first hydraulic cylinder 4 is arranged outside the guard plate 2 to provide power for the swing of the guard plate 2. The upper surface of the support base 1 is connected with a gantry 5 to provide a supporting force for the second hydraulic cylinder 6. A second hydraulic cylinder 6 is arranged below the gantry 5. The power output of the second hydraulic cylinder 6 provides power for the pressure head 8. A pressure sensor 7 is installed at the output end of the second hydraulic cylinder 6. After the pressure head 8 contacts the building structure, the pressure sensor generates a pressure signal, and the pressure value borne by the building structure is judged through the signal sent by the pressure sensor 7. The pressure head 8 is detachably connected below the pressure sensor 7. The contact between the pressure head 8 and the building structure can play a protective function for the pressure sensor 7. The upper surface of the support base 1 is connected with a test bench 9, and the test bench 9 is located below the pressure head 8. The test bench 9 can play a supporting role for the building structure.

[0024] Two support frames 10 are connected to the upper surface of the support base 1, and the two support frames 10 are symmetrical. At the same time, the two support frames 10 are located outside the inspection table 9. The support frames 10 provide support for a relatively long building structure and maintain the stability of the building structure. A clamping groove 11 is formed on the inner side of the support frame 10. The building structure to be inspected is placed inside the clamping groove 11. The clamping groove 11 can accommodate the building structure. A clamping plate 12 is slidably connected to the inner wall of the clamping groove 11. After the clamping plate 12 moves to a position, it tightly contacts the building structure, which can improve the stability of the building structure during inspection and further improve the inspection accuracy. A lead screw 13 is threadedly connected to the inner side of the support frame 10. One end of the lead screw 13 is fixedly rotatably connected to one side of the clamping plate 12. The rotation of the lead screw 13 provides power for the clamping plate 12 to move.

[0025] A mounting seat 14 is detachably connected to the outer surface of the gantry 5. One side of the mounting seat 14 is connected to the fixed end of the second hydraulic cylinder 6. After the mounting seat 14 is disassembled, the installation position can be reselected. When the mounting seat 14 moves to the installation position, the second hydraulic cylinder 6, the pressure sensor 7, and the pressing head 8 are simultaneously driven to move. By moving the positions of the second hydraulic cylinder 6, the pressure sensor 7, and the pressing head 8, different positions of the building structure can be inspected.

[0026] A base 15 is connected to the upper surface of the support base 1. By supporting the first hydraulic cylinder 4 through the base 15, a support force can be provided for the first hydraulic cylinder 4 and the stability of the first hydraulic cylinder 4 during power output can be maintained. The inner side of the base 15 is fixedly rotatably connected to the fixed end of the first hydraulic cylinder 4. A rotating shaft 16 is connected to the outer surface of the baffle 3. The baffle 3 receives power through the rotating shaft 16. The outer surface of the rotating shaft 16 is fixedly rotatably connected to the output end of the first hydraulic cylinder 4.

[0027] It should be noted that during the actual use of the device, first, the building structure is placed on the support frame 10 or the inspection table 9. According to the shape requirements of the building structure, a suitable support method is selected. If the building structure is relatively long, it can be placed on the support frame 10. After rotating the lead screw 13 to push the clamping plate 12 into contact with the building structure and form extrusion on the building structure, then the first hydraulic cylinder 4 is started to pull the baffle 3 to swing towards the guard plate 2. Subsequently, the baffle 3 contacts the guard plate 2, and at the same time, the positioning block 17 is inserted into the positioning groove 18. Then the second hydraulic cylinder 6 is started to push the pressing head 8 into contact with the building structure. After the pressing head 8 continuously applies pressure to the building structure, the building structure deforms and cracks, and the sand and gravel fly outwards. The flying sand and gravel impact on the surfaces of the baffle 3 and the guard plate 2, and the flying sand and gravel are intercepted by the baffle 3 and the guard plate 2.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model.
