Description

Technical Field

[0001] This utility model relates to a protective structure, and more specifically, to a portable temporary pile hole protection structure for construction sites. Background Technology

[0002] The fundamental purpose of pile holes is to create a space in the soil to place precast piles or pour concrete to form cast-in-place piles. During construction, workers use large drilling rigs to drill holes at designated locations, penetrating the loose soil layer until reaching the bearing layer required by the design. Precast retaining walls are used to prevent the well walls from collapsing. In actual construction, it has been found that due to the intermittent processes and technical gaps in the on-site pile foundation construction, the pile holes have idle time, posing a significant safety hazard. Usually, scattered materials on site are used to piece together a cover that is easy to walk on and cover the hole opening. However, such a cover cannot support too much weight. Therefore, a portable temporary pile hole protection structure is needed on the construction site. This device can provide support for the cover pieced together from scattered materials on site and can accommodate retaining wall buckles of different sizes.

[0003] For the reasons mentioned above, the problem addressed in this application is how to provide support for coverings assembled from scattered materials on site and how to accommodate wall retainers of different sizes. Utility Model Content

[0004] To address the shortcomings of existing technologies, a portable temporary pile hole protection structure for construction sites is provided. This device can provide support for coverings assembled from scattered materials on site and is adaptable to retaining clips of different sizes.

[0005] To achieve the above objectives, the following technical solution is provided: a portable temporary pile hole protection structure for construction sites, comprising a fixed shaft, a positioning component, an extension component, an abutment component, and a support component. The positioning component is installed on the fixed shaft, the extension component is installed on the positioning component, the abutment component is installed on the extension component, and the support component is installed on the abutment component. The extension component is used to form different lengths by changing its shape. Multiple sets of the positioning component, the extension component, the abutment component, and the support component are provided.

[0006] As the extension component extends, the contact component abuts against the inner wall of the retaining wall, and the support component abuts against the top of the retaining wall.

[0007] In summary, the above technical solution has the following beneficial effects: the fixed shaft can be a long column inserted into the center of the pile hole as the reference for the entire structure, or a short column suspended in the air. Multiple positioning components surround the fixed shaft, which can determine the unfolding direction and initial position of the extension component. The extension component can adopt a structure such as a telescopic rod or a folding arm, which can achieve the effect of elongation by changing its shape, thereby adjusting its length extending outward from the center. When the extension component extends to the predetermined position, the abutting component installed at its end will tightly abut against the inner wall of the pile hole retaining wall, providing lateral support force to prevent the structure from moving inward or tilting. The support component installed above the abutting component moves to the top edge of the pile hole and abuts against the top of the retaining wall, forming a covering and supporting surface with the ground component. This can provide support for the covering spliced ​​from the scattered materials on site and adapt to retaining wall buckles of different sizes.

[0008] Multiple sets of support components, extension components, and abutment components work simultaneously to form multiple dispersed support points on the inner sidewalls of the pile hole and the top edge of the hole opening, together forming a stable and reliable protective cover. It can form a rigid barrier with a near 90° bend on the inner wall of the pile hole and the edge of the hole opening, effectively preventing personnel, tools, and materials from falling accidentally. Its safety is far higher than that of a simple cover plate.

[0009] The extension components can be retracted or folded, and the contact and support components can also be folded up, making the overall structure compact, easy to transport and carry. Installation can be completed by inserting the fixed shaft and unfolding and adjusting the extension components, saving time and effort. One set of equipment can be adjusted to be suitable for various specifications of pile holes commonly found on construction sites, reducing the types of protective equipment that need to be equipped.

[0010] In this invention, the side contact points and top support points of the protective wall are simultaneously tightened by an adjustable extension component. By utilizing the principle of multi-point coordinated support, a sturdy and reliable rigid protective cover is formed, resulting in high stability and strong adaptability. It also has the ability to be portable and quickly deployed, effectively solving the problems of easy displacement and unreliable protection of traditional coverings. It is particularly suitable as a temporary safety protection measure for pile holes on construction sites. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] Reference Figure 1-2 As shown, a portable temporary pile hole protection structure for construction sites includes a fixed shaft 1, a positioning component 2, an extension component 3, an abutment component 4, and a support component 5. The positioning component 2 is installed on the fixed shaft 1, the extension component 3 is installed on the positioning component 2, the abutment component 4 is installed on the extension component 3, and the support component 5 is installed on the abutment component 4. The extension component 3 is used to form different lengths by changing its shape. The positioning component 2, the extension component 3, the abutment component 4, and the support component 5 are all provided in multiple sets.

[0021] When the extension component 3 extends, the contact component 4 abuts against the inner wall of the protective wall, and the support component 5 abuts against the top of the protective wall.

[0022] The fixed shaft 1 can be a long column inserted into the center of the pile hole as the reference for the entire structure, or a short column suspended in the air. Multiple positioning components 2 surround the fixed shaft 1, which can determine the unfolding direction and initial position of the extension component 3. The extension component 3 can adopt a structure such as a telescopic rod or a folding arm, which can achieve the effect of elongation by changing its own shape, thereby adjusting its length extending outward from the center. When the extension component 3 is extended to the predetermined position, the abutting component 4 installed at its end will tightly abut against the inner wall of the pile hole retaining wall, providing lateral support force to prevent the structure from moving inward or tilting. The support component 5 installed above the abutting component 4 moves to the top edge of the pile hole and abuts against the top of the retaining wall, forming a covering and supporting surface with the ground component. This can provide support for the covering spliced ​​from the scattered materials on site and adapt to retaining wall buckles of different sizes.

[0023] Multiple sets of support components 5, extension components 3, and abutment components 4 work simultaneously to form multiple dispersed support points on the inner sidewalls of the pile hole and the top edge of the hole, together forming a stable and reliable protective cover. It can form a rigid barrier with a near 90° bend on the inner wall of the pile hole and the edge of the hole, effectively preventing personnel, tools, and materials from falling accidentally. Its safety is far higher than that of a simple cover plate.

[0024] The extension component 3 can be retracted or folded, and the anti-collision and support component 5 can also be folded up, making the overall structure compact, easy to transport and carry. Installation can be completed by inserting the fixed shaft 1 and unfolding and adjusting the extension component 3, saving time and effort. One set of equipment can be adjusted to be suitable for various specifications of pile holes commonly found on construction sites, reducing the types of protective equipment that need to be equipped.

[0025] In this utility model, the adjustable extension component 3 simultaneously presses the side contact point and the top support point of the protective wall together, forming a solid and reliable rigid protective cover by utilizing the principle of multi-point collaborative support. This results in high stability and strong adaptability, as well as the ability to be portable and quickly deployed. It effectively solves the problems of easy displacement and unreliable protection of traditional coverings, and is particularly suitable as a temporary safety protection measure for pile holes on construction sites.

[0026] Furthermore, the positioning component 2 includes a positioning seat 21 and a drive component 22. The positioning seat 21 is fixedly connected to the fixed shaft 1, and the drive component 22 is mounted on the positioning seat 21. The drive component 22 is used to drive the extension component 3 to change its shape.

[0027] Furthermore, the abutment component 4 includes an abutment plate 41 and an elastic buffer member 42. The elastic buffer member 42 is fixedly connected to the abutment plate 41 and is used to abut the inner wall of the protective wall.

[0028] Furthermore, the abutment component 4 also includes a first track 43 and a first slider 44, the positioning component 2 also includes a second track 23 and a second slider 24, the extension component 3 includes a first rotating arm 31 and a second rotating arm 32, the first slider 44 is slidably connected to the first track 43, one end of the first rotating arm 31 is rotatably connected to the positioning seat 21, the other end of the first rotating arm 31 is rotatably connected to the first slider 44, the second slider 24 is slidably connected to the second track 23, one end of the second rotating arm 32 is rotatably connected to the second slider 24, the other end of the second rotating arm 32 is rotatably connected to the abutment plate 41, and the second slider 24 is connected to the drive component 22.

[0029] Furthermore, the first rotating arm 31 and the second rotating arm 32 cross in an "X" shape and are hinged at the center.

[0030] The positioning component 2, extension component 3, and abutment component 4 form a radially extendable positioning and abutment mechanism with a buffer function. The motion of the drive component 22 is converted into the radial movement of the abutment plate 41 by the principle of the X-shaped cross linkage mechanism. When the drive component 22 drives the extension component 3 to extend, the abutment plate 41 generates a linear displacement. Specifically, the first slider 44 slides along the first track 43. Since the two rotating arms are hinged at the center, the movement of the second slider 24 driven by the drive component 22 will force the first slider 44 to move in the opposite direction along its track, thereby changing the opening angle of the entire "X"-shaped linkage. From the horizontal direction, the horizontal length of the first rotating arm 31 and the second rotating arm 32 changes, thereby driving the abutment plate 41 to move. The first rotating arm 31 mainly plays the role of supporting the overall stability.

[0031] After the contact plate 41 is pushed to the designated position, the elastic buffer 42 on it will abut against the inner wall of the protective wall. The elastic buffer 42 can absorb the vibration or impact force at the moment of contact and during operation, avoid damage or excessive stress that may be caused by rigid contact, thereby protecting the equipment and the protective wall. Considering that the protective wall itself is curved, the elastic buffer 42 can also compensate for the slight changes in the inner diameter of the protective wall or the manufacturing installation error, ensuring stable contact.

[0032] Furthermore, the drive assembly 22 includes a motor 221, a drive shaft 222, a threaded sleeve 223, and a threaded rod 224. The drive shaft 222 is connected to the motor 221, the drive shaft 222 is fixedly connected to the threaded sleeve 223, the threaded sleeve 223 is threadedly connected to the threaded rod 224, and the threaded rod 224 is fixedly connected to the second slider 24.

[0033] The motor 221 can rotate forward or reverse, and then control the movement of the threaded rod 224 through the rotating threaded sleeve 223. The movement of the threaded rod 224 will drive the second slider 24 to move. The combination of the first rotating arm 31 and the second rotating arm 32 can realize the movement of the contact plate 41 through the movement of the second slider 24.

[0034] Furthermore, the support component 5 includes a first support member 51, which is fixedly connected to the contact plate 41. The first support member 51 has a first through hole 52 and is used to abut the top of the protective wall.

[0035] Furthermore, the positioning component 2 also includes a second support member 25, which is fixedly connected to the positioning seat 21, and the second support member 25 is provided with a second through hole 26.

[0036] Since the materials are pieced together using miscellaneous materials found on site, discarded steel bars and other columnar objects can also be inserted into the first through hole 52 and the second through hole 26 to achieve better stability and support.

[0037] Furthermore, the support assembly 5 also includes a clamping member 53, a connecting post 54, and a pressing member 55. The first support member 51 is also provided with a third through hole. The two ends of the connecting post 54 are fixedly connected to the clamping member 53 and the pressing member 55 respectively. The connecting post 54 is slidably connected in the third through hole. The clamping member 53 is located in the first through hole 52, and the pressing member 55 is located outside the first through hole 52.

[0038] Since the size of the column inserted into the first through hole 52 and the second through hole 26 may not be compatible, a weight can be placed on the pressing member 55 so that the clamping member 53 presses down on the column and prevents the column from detaching.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
