Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, relates to a device for shielding the holes of pipe piles. Background Technology

[0002] Currently, the protective measures for the central hole of the pipe pile are relatively limited. Some construction sites only use simple cover plates or coverings to shield it. Such protective methods cannot fit tightly into the pipe pile hole and are easily displaced by external forces, allowing mud, debris and other objects to still enter the hole and affecting the quality of subsequent core concrete pouring.

[0003] Meanwhile, due to the lack of reliable fixing methods, these simple protective measures are difficult to resist trampling by people or collisions with construction machinery, and cannot effectively avoid safety risks. They are also inconvenient to dismantle as construction progresses, affecting construction efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a pipe pile hole shielding device, which aims to use a locking mechanism to fix the plate in the pipe pile hole in a self-locking manner, so as to be stable and reliable.

[0005] According to a first aspect of the present invention, a pipe pile hole shielding device is provided, comprising a circular plate body, wherein the plate body is provided with a plurality of locking mechanisms;

[0006] The locking mechanism includes a connecting tube and a wedge block. The connecting tube is disposed on the top of the plate and can slide horizontally. The wedge block is fixed at one end of the connecting tube away from the center of the plate. The side of the wedge block facing away from the connecting tube is an inclined surface, which is inclined upward in the direction away from the plate.

[0007] A spring connects the wedge block to the plate, and the spring causes the connecting pipe to slide outward so that the inclined surface contacts the inner wall of the pipe pile hole.

[0008] In the aforementioned pipe pile hole shielding device, the top of the plate is provided with an annular protrusion around its center, the connecting pipe passes through the annular protrusion, the spring is sleeved on the connecting pipe, and the spring is located between the annular protrusion and the wedge block.

[0009] In the aforementioned pipe pile hole shielding device, the locking mechanism includes two connecting pipes, which are arranged at intervals in the vertical direction, and at least one connecting pipe is fitted with a spring.

[0010] In the aforementioned pipe pile hole shielding device, the inclined surface is provided with serrated protrusions.

[0011] In the aforementioned pipe pile hole shielding device, the outer edge of the plate is provided with a rubber layer, which is used to contact the inner wall of the pipe pile hole.

[0012] In the aforementioned pipe pile hole shielding device, there are four locking mechanisms that are evenly distributed around the center of the plate.

[0013] In the aforementioned pipe pile hole shielding device, the top of the plate is provided with a grid-shaped reinforcing rib, which extends to the annular protrusion.

[0014] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0015] In this invention, a spring is used to allow the wedge block to lock onto the inner wall of the pipe pile hole, thereby allowing the plate to cover the pipe pile hole and prevent foreign objects from falling into it. Since the wedge block contacts the inner wall of the pipe pile hole with its inclined surface, when the plate is subjected to a downward force, the wedge block will lock more tightly, achieving self-locking. The plate can stably and reliably cover the pipe pile hole, resulting in better safety. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0024] Reference Figures 1 to 3 As shown, a pipe pile hole shielding device includes a circular plate 1, on which multiple locking mechanisms 2 are provided;

[0025] The locking mechanism 2 includes a connecting pipe 21 and a wedge block 22. The connecting pipe 21 is located on the top of the plate 1 and can slide horizontally. The wedge block 22 is fixed at one end of the connecting pipe 21 away from the center of the plate 1. The side of the wedge block 22 facing away from the connecting pipe 21 is an inclined surface 221, which is inclined upward in the direction away from the plate 1.

[0026] A spring 23 is connected between the wedge block 22 and the plate 1. The spring 23 causes the connecting pipe 21 to slide outward so that the inclined surface 221 contacts the inner wall of the pipe pile hole.

[0027] In use, plate 1 enters the pile hole, thus shielding the pile hole. Then, connecting pipe 21 moves inward to allow wedge block 22 to partially enter the pile hole. Then, connecting pipe 21 is released, and under the action of spring 23, connecting pipe 21 slides outward, allowing wedge block 22 to contact the pile hole and lock into it. Since wedge block 22 contacts the inner wall of the pile hole with its inclined surface 221, when plate 1 is subjected to downward force, wedge block 22 will lock more tightly, achieving self-locking. Plate 1 can stably and reliably shield the pile hole, providing superior safety.

[0028] In this embodiment, the top of the plate 1 is provided with an annular protrusion 11 around its center, the connecting tube 21 passes through the annular protrusion 11, the spring 23 is sleeved on the connecting tube 21, and the spring 23 is located between the annular protrusion 11 and the wedge block 22.

[0029] Specifically, the annular protrusion 11 has a through hole adapted to the connecting pipe 21, and the connecting pipe 21 passes through the through hole, allowing the connecting pipe 21 to slide horizontally. The spring 23 is supported between the annular protrusion 11 and the wedge block 22, giving the wedge block 22 a tendency to move outward. The position of the wedge block 22 can also be controlled by manually pulling the connecting pipe 21. When placing the device, the position of the wedge block 22 can be manually controlled to ensure that the wedge block 22 can be locked into the hole of the pipe pile.

[0030] If the plate 1 is subjected to a downward force, even if the wedge block 22 slides, it will only further compress the spring 23, resulting in a greater elastic force and the wedge block 22 locking more tightly, thereby achieving the self-locking function.

[0031] In this embodiment, the connecting pipe 21 is provided with a blind hole. The connecting pipe 21 is pulled inward until the blind hole is located in the inner circle surrounded by the annular protrusion 11. Then, a pin is inserted into the blind hole. At this time, the wedge block 22 can enter the pipe pile hole. The pin cannot pass through the through hole on the annular protrusion 11, so the connecting pipe 21 cannot slide outward. After the plate 1 is placed, it is confirmed that the position of the wedge block 22 can be locked at the edge of the pipe pile hole. Then, the pin is removed, and the connecting pipe 21 automatically slides outward. The wedge block 22 is locked onto the inner wall of the pipe pile hole.

[0032] In this embodiment, the spring 23 needs to be selected according to the actual situation to ensure that the elastic force can make the wedge block 22 lock into the hole of the pipe pile; of course, even if there is a locking mechanism 2, it does not mean that a person can completely step on the plate 1. It only means that under slight stepping or collision, the locking mechanism 2 can prevent the plate 1 from sinking.

[0033] In this embodiment, a locking mechanism 2 includes two connecting pipes 21 and a wedge block 22. Both connecting pipes 21 are connected to the wedge block 22. The two connecting pipes 21 are arranged at intervals in the vertical direction. At least one connecting pipe 21 is fitted with a spring 23. The wedge block 22 can be prevented from rotating by the restriction of the two connecting pipes 21, and the locking mechanism 2 is made stronger. The two connecting pipes 21 can support the wedge block 22 together.

[0034] A retaining ring is provided on one of the connecting pipes 21 of the locking mechanism 2. The retaining ring is located at the end of the connecting pipe 21 away from the wedge block 22 to prevent the connecting pipe 21 from disengaging from the through hole.

[0035] In this embodiment, the inclined surface 221 is provided with serrated protrusions, which can improve the friction of the inclined surface 221 and allow the wedge block 22 to be better clamped on the inner wall of the pipe pile hole.

[0036] In this embodiment, the outer edge of the plate 1 is provided with a rubber layer 3. The rubber layer 3 is used to contact the inner wall of the pipe pile hole. The rubber layer 3 is flexible and can fill the gap between the outer edge of the plate 1 and the inner wall of the pipe pile hole, which facilitates the arrangement of the plate 1.

[0037] In this embodiment, there are four locking mechanisms 2 evenly distributed around the center of the plate 1. Through the cooperation of the four wedge blocks 22, the plate 1 can be fixed in the hole of the pipe pile, which is firm and stable.

[0038] In this embodiment, the top of the plate 1 is provided with a grid-shaped reinforcing rib 12. The reinforcing rib 12 extends to the annular protrusion 11. The reinforcing rib 12 can improve the strength of the plate 1. By designing the reinforcing rib 12 into a grid shape, the inner circle enclosed by the annular protrusion 11 has multiple empty areas. The connecting pipe 21 cooperates with these empty areas to avoid interference between the connecting pipe 21 and the reinforcing rib 12 when the connecting pipe 21 slides.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
