Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pressure plates, in particular to a pressure plate for foundation detection. Background Art

[0002] The bearing capacity test of foundation is mainly used in natural foundation or artificial composite foundation to detect the quality of foundation and ensure the strength of the building supported by the foundation. Among them, flat plate load test is more extensive. Flat plate load test often requires the use of a pressure plate that bears gravity. Traditional pressure plates are often embedded in the foundation surface after use, and grooves are pressed out on the foundation surface, or the pressure plates are adsorbed on the foundation surface, which is not convenient to take out and retract after use. The operator needs to destroy the ground to take out the pressure plate or use a crowbar with the cooperation of multiple people. In the patent "Pressure Plate for Foundation Bearing Capacity Detection" authorized and announced by the State Intellectual Property Office on August 4, 2023, with announcement number CN219470877U, the above patent installs a pull-out component on the pressure plate to facilitate the removal of the pressure plate from the groove in the ground, but the above device cannot save effort in the process of removing the pressure plate from the groove in the ground. At the same time, the size of the pressure plate cannot be changed, and the appropriate size of the pressure plate cannot be selected according to demand. For this reason, we designed a pressure plate for foundation testing. Utility Model Content

[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] A pressure plate for foundation testing, such as Figure 1 , 2 As shown in , 3, and 4, it includes a pressure plate, which is characterized in that: the pressure plate includes a fixed plate 1, a center plate 2 is fixedly installed on the lower side of the fixed plate 1, and a plurality of annular plates 5 are detachably installed on the outer periphery of the center plate 2, and adjacent annular plates 5 are detachably installed with each other, the diameter of the fixed plate 1 is larger than the diameter of the outermost annular plate 5, threaded holes 3 are respectively provided on the annular plates 5, and reserved holes corresponding to the plurality of threaded holes 3 are provided on the fixed plate 1, and the same bolt 4 is installed in the corresponding reserved holes and threaded holes 3, and the annular plate 5 is fixedly connected to the fixed plate 1 by installing the same bolt 4 in the corresponding reserved holes and threaded holes 3. The utility model has a simple structure and an ingenious design. The pressure plate is composed of a center plate 2 and a plurality of annular plates 5 that can be detachably installed. It is more labor-saving to take out the center plate 2 and the plurality of annular plates 5 from the groove on the ground in multiple times, and a pressure plate of a suitable size can be selected according to demand, which can meet actual needs and is suitable for promotion. When using the utility model, several annular plates 5 are selected as needed to be installed on the center plate 2, and then the position of the annular plate 5 is adjusted to align the threaded holes 3 on the corresponding annular plates 5 with the reserved holes on the fixing plate 1, and the bolts 4 are threadedly installed in the corresponding threaded holes 3 and the reserved holes, so that the annular plate 5 is fixedly installed on the fixing plate 1, and then the pressure plate can be placed on the foundation to be tested for inspection; after the inspection is completed, if the pressure plate is embedded in the ground, it is necessary to remove several bolts 4 first, and then separate the fixing plate 1 and the center plate 2 from the corresponding annular plate 5. Since the center plate 2 has a smaller contact area with the foundation than the entire pressure plate, the force to separate it from the foundation is also smaller, thereby achieving a labor-saving effect. After that, the corresponding annular plates 5 can be disassembled separately according to the above operation to remove the pressure plate.

[0018] Specifically, as shown in the figure, the outer peripheries of the center plate 2 and the several annular plates 5 described in this embodiment are respectively fixed with sliders 20, and the inner peripheries of the several annular plates 5 are respectively provided with slide grooves 21 corresponding to the sliders 20, and the inner walls of the slide grooves 21 can be slidably contacted with the outer walls of the sliders 20, and the sliders 20 are respectively slidably installed in the corresponding slide grooves 21, and the slide grooves 21 include transverse arc grooves 23, and the side walls of the arc grooves 23 are provided with vertical vertical grooves 22, and the upper side of the vertical grooves 22 is open. During installation, the slider 20 is firstly required to be aligned with the corresponding vertical grooves 22 and inserted, and when the slider 20 slides to the bottom of the vertical grooves 22, the corresponding center plate 2 or annular plate 5 is rotated to slide the slider 20 into the inside of the arc grooves 23, and through the cooperation of the slider 20 and the slide grooves 21, the corresponding center plate 2 or annular plate 5 cannot move relative to each other in the up and down directions.

[0019] Further, as shown in the figure, the sliders 20 and the slide grooves 21 on the center plate 2 and the plurality of annular plates 5 in this embodiment are provided with two groups, and are symmetrically distributed along the center of the center plate 2 and the plurality of annular plates 5. The symmetrically distributed sliders 20 and the slide grooves 21 increase the stability of the connection between the center plate 2 and the plurality of annular plates 5.

[0020] Furthermore, as shown in the figure, corresponding arc-shaped tooth grooves 40 are respectively provided on the side walls of the adjacent annular plates 5 of this embodiment. When the annular plate 5 is fixedly connected to the fixed plate 1, the side walls of the corresponding arc-shaped tooth grooves 40 are aligned, and the corresponding two arc-shaped tooth grooves 40 can be matched to install the gear column 41, and the handle 42 is fixedly installed on the gear column 41. When in use, the gear column 41 needs to be matched to install in the middle position of the arc-shaped tooth groove 40, and the gear column 41 can be rotated by holding the handle 42, which can drive the two arc-shaped tooth grooves 40 meshing with it to rotate in opposite directions, thereby causing the two adjacent annular plates 5 to rotate relative to each other; when the annular plate 5 rotates, air can easily enter between the annular plate 5 and the foundation, making it easier to remove the pressure plate.

[0021] Furthermore, as shown in the figure, the handle 42 of this embodiment is tilted upward at one end away from the gear column 41. The tilted end of the handle 42 is more convenient for gripping, avoiding injuries caused by touching the annular plate 5 when the handle 42 is located on the upper side of the annular plate 5.

[0022] Furthermore, as shown in the figure, the fixing plate 1 of the present embodiment is provided with a round tooth groove 60, the round tooth groove 60 is coaxially arranged with the fixing plate 1, and the gear column 41 can be fitted in the round tooth groove 60. By fitting the gear column 41 in the round tooth groove 60 and rotating the gear column 41 by the handle 42, it is convenient to make the center plate 2 and the annular plate 5 rotate relative to each other.

[0023] Furthermore, as shown in the figure, the fixing plate 1 and the plurality of annular plates 5 of this embodiment are provided with finger grooves 70. Inserting fingers into the finger grooves 70 makes it easier to separate the corresponding fixing plate 1 or annular plate 5 from the foundation surface.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
