Description

Technical Field

[0001] This utility model relates to the field of road surface testing equipment technology, and in particular to a deflection testing device for building engineering. Background Technology

[0002] A pavement deflectometer is based on the lever principle and is used to measure the pavement deflection value between the two rear wheels of a vehicle. Under load, the pavement undergoes localized subsidence, i.e., vertical deformation. The shape reflected by the pavement is a basin centered on the deflection point. When the pressure is removed, elasticity allows the pavement to return to its original shape, and the deflection basin disappears. The difference before and after the pressure is applied is called the deflection value. The total deflection and elastic deflection are not equal, meaning that after the load is removed, the pavement deflection does not completely disappear; a small amount of residual deformation remains. Deflection is one of the important technical indicators for highway design and highway engineering quality evaluation. The deflectometer is suitable for measuring the pavement rebound deflection value.

[0003] A Chinese patent publication number CN218436522U discloses a deflection testing device for building engineering, comprising a testing device and a moving device. The testing device includes a Beckman beam, a support base, a support frame, and a dial indicator. A column and two locking posts are welded to the top right end of the Beckman beam. The support base is rotatably connected to the Beckman beam via a rotating shaft. The support frame is located at the right end of the Beckman beam. The dial indicator is connected to the support frame via a connecting plate, and the bottom of the dial indicator contacts a disc at the top of the column. The moving device includes a connecting cylinder, a moving rod, a connecting rope, a U-shaped frame, a collar, and a spring. The connecting cylinder is fixed to the bottom left end of the Beckman beam by bolts, and the moving rod slides in contact with the inner wall of the connecting cylinder via the spring.

[0004] The U-shaped frame and support base in the above device are installed on the side wall of the Beckman beam. When the Beckman beam detection device is not needed, the U-shaped frame and support base are not easy to recycle. If they are recycled as is, the U-shaped frame and support base will occupy a large space and are not convenient to store.

[0005] Therefore, it is necessary to provide a deflection detection device for building engineering to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a deflection detection device for building engineering, which solves the problem that the U-shaped frame and support base would occupy a large space and be inconvenient to store if they were recycled in their original state.

[0007] To solve the above-mentioned technical problems, this utility model provides a deflection detection device for building engineering, including a strip plate one, a strip plate two inserted and connected inside the strip plate one, a rectangular plate fixedly installed at the bottom left end of the strip plate two, a round rod fixedly installed at the top right end of the strip plate one, a locking component for limiting the position installed between the strip plate one and the strip plate two, a support component installed on the outer wall of the strip plate one, and a limiting component installed between the support component and the outer wall of the strip plate one.

[0008] Preferably, the support assembly includes a base plate, and a support plate is fixedly installed on the top of each of the two sets of base plates. The two sets of support plates are rotatably connected to the front and rear outer walls of the strip plate, respectively.

The left end of the guide rod is fixedly connected to the side wall of the slider, and a spring is fixedly installed between the side wall of the slider and the side wall of the installation block. The spring is sleeved on the outside of the guide rod.

[0011] Preferably, the locking assembly includes a limiting hole 1, several sets of the limiting holes 1 are evenly opened on the side wall of the strip plate 2, a mounting bracket is fixedly installed near the outlet of the strip plate 1, a limiting rod is inserted into the side wall of the mounting bracket, a limiting hole 2 is opened on the outer wall near the outlet of the strip plate 1, the limiting rod is inserted into the limiting hole 2, and a handle is fixedly installed at the end of the limiting rod.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 A schematic diagram of a preferred embodiment of a deflection detection device for building engineering provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the internal structure of the strip plate shown; Figure 3 for Figure 1 The diagram shows the structure of the rectangular frame. Figure 4 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 5 for Figure 3The enlarged schematic diagram of part B is shown. A deflection detection device for building engineering includes: a strip plate 1, a rectangular cavity inside the strip plate 1 extending through the left end of the strip plate 1, a strip plate 2 inserted into the strip plate 1, a rectangular plate 7 fixedly installed at the bottom left end of the strip plate 2, a round rod 3 fixedly installed at the top right end of the strip plate 1, a locking component 6 for limiting the position between the strip plate 1 and the strip plate 2, a support component 4 installed on the outer wall of the strip plate 1, and a limiting component 5 installed between the support component 4 and the outer wall of the strip plate 1.

[0025] The support assembly 4 includes a base plate 41, and a support plate 42 is fixedly installed on the top of each of the two sets of base plates 41. The two sets of support plates 42 are rotatably connected to the outer walls of the front and rear sides of the strip plate 1, respectively.

[0026] The support plate 42 is rotatably connected to the strip plate 1 to form a lever. When no testing is required, the support plate 42 is rotated to be parallel to the strip plate 1, and then the support plate 42 is horizontally restricted by the limiting component 5, which facilitates subsequent storage.

[0027] The limiting component 5 includes a slide groove 56. Two sets of slide grooves 56 are formed at the top and bottom of the strip plate 1. Slider 55 is slidably connected to the inner wall of each set of slide grooves 56. A rectangular frame 51 is fixedly installed between the outer walls of the two sets of slider 55.

[0028] After rotating the support plate 42 to be horizontal with the strip plate 1, push the rectangular frame 51 to move towards the support plate 42 until the rectangular frame 51 covers the support plate 42, thus restricting the movement of the support plate 42.

[0029] An installation block 53 is fixedly installed on the outer right side of the slide 56. A guide rod 54 is inserted into the side wall of the installation block 53. The left end of the guide rod 54 is fixedly connected to the side wall of the slider 55. A spring 52 is fixedly installed between the side wall of the slider 55 and the side wall of the installation block 53. The spring 52 is sleeved on the outside of the guide rod 54.

[0030] In order to fit the support plate 42, the rectangular frame 51 is first moved to the right. At this time, the slider 55 pushes the guide rod 54 to slide to the right, so that the spring 52 is compressed. When the rectangular frame 51 reaches a certain position, the support plate 42 is rotated to be parallel to the strip plate 1. Then the rectangular frame 51 is released, and the spring 52 will automatically push it to the left until the rectangular frame 51 fits the support plate 42.

[0031] The locking component 6 includes a limiting hole 61, and several sets of the limiting holes 61 are evenly opened on the side wall of the strip plate 2. A mounting bracket 66 is fixedly installed near the outlet of the strip plate 1. A limiting rod 62 is inserted into the side wall of the mounting bracket 66. A limiting hole 65 is opened on the outer wall near the outlet of the strip plate 1. The limiting rod 62 is inserted into the limiting hole 65. A handle 63 is fixedly installed at the end of the limiting rod 62.

[0032] Hold the handle 63 and pull the other end out of the limiting hole 2 65, so that the strip plate 2 can be retracted or pulled out. When the limiting hole 1 61 is aligned with the limiting hole 2 65, insert the limiting rod 62 back into the limiting hole 2 65 to restrict the movement of the strip plate 2.

[0033] A second spring 64 is fixedly installed between the outer wall of the mounting bracket 66 and the side wall of the handle 63, and the second spring 64 is sleeved on the outside of the limiting rod 62.

[0034] When the first limiting hole 61 is aligned with the second limiting hole 65, release the handle 63, and the second spring 64 will automatically drive the limiting rod 62 to insert into the first limiting hole 61.

[0035] Both sets of base plates 41 are connected to tapered rods 8, which penetrate the base plates 41.

[0036] By inserting the tapered rod 8 into the road surface to be tested using external force, the base plate 41 can be stably restrained.

[0037] The working principle of the deflection detection device for building engineering provided by this utility model is as follows:

[0038] The position of strip plate 2 can be controlled by locking component 6. When testing is required, strip plate 2 can be pulled out from inside strip plate 1 and then limited by locking component 6. When not in use, locking component 6 can be opened to retract strip plate 2 into inside strip plate 1 for easy storage in a limited space. The limit component 5 can restrict the rotation of the flat retractable support component 4, which is also convenient for subsequent storage.

[0039] Compared with related technologies, the deflection detection device for building engineering provided by this utility model has the following beneficial effects:

[0040] To fit the support plate 42, first move the rectangular frame 51 to the right. At this time, the slider 55 pushes the guide rod 54 to slide to the right, so that the spring 52 is compressed. When the rectangular frame 51 reaches a certain position, rotate the support plate 42 to be parallel to the strip plate 1, and then release the rectangular frame 51. The spring 52 will automatically push it to the left until the rectangular frame 51 fits the support plate 42. The parallel support plate 42 reduces the space area, making it easier to store later.

[0041] Hold the handle 63 and pull the other end out of the limiting hole 2 65, so that the strip plate 2 can be retracted or pulled out. When the limiting hole 1 61 is aligned with the limiting hole 2 65, release the handle 63, and the spring 2 64 will automatically drive the limiting rod 62 to insert into the limiting hole 1 61.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
