Description

Technical Field

[0001] This utility model belongs to the field of construction site enclosure technology, and in particular relates to a new type of convenient construction enclosure. Background Technology

[0002] Construction sites for current construction projects cannot function without construction fences. These fences separate the construction site from the external environment, creating a relatively enclosed construction environment and separating the construction site from pedestrians and vehicles. After the project is completed, the construction fences need to be dismantled and removed to restore the original ground.

[0003] At construction sites, the common method for fixing stone pier enclosures is to use expansion bolts to fix the enclosures to the stone piers. This method of fixing with expansion bolts is not only inefficient and time-consuming, but also requires drilling holes in the stone piers with an impact drill or hammer drill before installing the expansion bolts, which generates noise and dust pollution. Furthermore, the expansion bolts cannot be reused, and repeated drilling is not conducive to the reuse of stone piers, resulting in a low turnover rate and a reduced lifespan of the stone piers. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a new type of convenient construction fence to solve the problems of low construction efficiency and low turnover rate in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides a novel and convenient construction site enclosure, comprising:

[0006] The guardrail arm has multiple guardrail slots along its own axial direction.

[0007] The limiting movable plate is perpendicular to and fixedly connected to the top surface of the guardrail upright and the limiting movable plate. The limiting movable plate has four U-shaped through slots with a rectangular structure along its own thickness direction.

[0008] Multiple guardrail panels, the number of which is equal to the number of guardrail slots, and the two are inserted into each other in a one-to-one correspondence;

[0009] The stone pier body has two through slots with inverted T-shaped cross-sections along its own length at the top, and the two through slots are arranged in parallel.

[0010] The limiting moving plate and the stone pier are detachably connected via the connector.

[0011] Optionally, the through groove is a through groove design;

[0012] Alternatively, the through groove may be a through groove design, with one end of the through groove being higher than the other.

[0013] Optionally, the guardrail slot is wider on the outside and smaller on the inside.

[0014] Optionally, the guardrail slot is inclined at the top and lower at the bottom.

[0015] Optionally, the tilt angle of the guardrail slot is 30~60°.

[0016] Optionally, the guardrail slot has an inclination angle of 45°.

[0017] Optionally, the connector includes a screw head, a screw rod, and a nut. The screw head is perpendicular to and fixedly connected to one end of the screw rod. The screw head is located in the horizontal portion of the through groove with a T-shaped cross-section and is slidably fitted. The screw rod passes through the vertical portion of the through groove with a T-shaped cross-section and the U-shaped through groove and is threadedly fitted to the nut.

[0018] Optionally, the width of the horizontal portion of the through-groove, which has a T-shaped cross-section, is greater than the diameter of the screw head.

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0031] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0032] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0033] In this embodiment, please refer to Figures 1 to 5 This utility model provides a new type of convenient construction fence, including: guardrail arm 1, limiting and moving plate 5, multiple guardrail plates 3, stone block body 8 and connecting piece 4, wherein the guardrail arm 1 has multiple guardrail slots 2 along its own axial direction.

[0034] The guardrail arm 1 is perpendicular to and fixedly connected to the top surface of the limiting moving plate 5. The limiting moving plate 5 has four U-shaped through slots with a rectangular structure along its thickness direction. The number of guardrail plates 3 is equal to the number of guardrail slots 2, and they are inserted one-to-one. The top of the stone pier 8 has two through slots 6 with an inverted T-shaped cross-section along its length direction, and the two through slots 6 are arranged in parallel. The limiting moving plate 5 and the stone pier 8 are detachably connected by the connector 4. Several guardrail arms 1, limiting moving plates 5, guardrail plates 3, and stone piers 8 are provided according to construction requirements.

[0035] According to construction requirements, stone piers 8 are arranged sequentially. Connectors 4 are inserted into the through slots 6. Connectors 4 are connected one-to-one with the U-shaped through slots on the limiting moving plate 5. The limiting moving plate 5 is connected to the top of the stone pier 8 through the connectors 4, which is convenient for disassembly and maintenance and ensures the firmness of the connection. The position of the limiting moving plate 5 on the stone pier 8 can be adjusted at will according to the length of the guardrail 3. The operation is convenient and simple. The guardrail arms 1 on adjacent stone piers 8 are fixed by repeated operation. Then, multiple guardrail 3 are inserted into multiple guardrail slots 2 on adjacent guardrail arms 1. The design of the guardrail slots 2 makes it easy to insert the guardrail 3 and align the position during installation, making the installation process smoother and shortening the installation time. This solves the problems of low construction efficiency, repeated drilling of stone piers which is not conducive to reuse, low turnover rate, and reduced service life of stone piers.

[0036] In this embodiment, please refer to Figure 1 The through-groove 6 is a through-groove design; or the through-groove 6 is a through-groove design, with one end of the through-groove 6 being higher than the other. A through-groove design makes installation more convenient, allowing workers to easily insert the connector 4 from either end of the groove. It also facilitates drainage, as water can drain smoothly through the groove and will not accumulate inside. Accumulated water can cause the connector 4 to rust and corrode, thus affecting the connection's strength. The through-groove design effectively extends the service life of the connector 4 and the entire connection structure. The bottom of the through-groove 6 can be higher at one end than the other, further facilitating the drainage of accumulated water.

[0037] In this embodiment, please refer to Figure 1 and Figure 4 The guardrail slot 2 is wider on the outside and narrower on the inside. This design allows for a good clamping effect on the guardrail panel 3. When the guardrail panel 3 is inserted into the guardrail slot 2, the smaller internal size of the slot 2 will compress the guardrail panel 3, making it fit tightly against the slot 2. This effectively limits the movement of the guardrail panel 3 within the slot 2, thereby enhancing the stability of the guardrail panel 3.

[0038] In this embodiment, please refer to Figure 1 and Figure 4 The guardrail slot 2 is inclined at the top and low at the bottom. The inclined guardrail slot 2 design facilitates the insertion of the guardrail panel 3, makes it easier to align the position during installation, and the inclined angle can also play a guiding role to a certain extent, making the installation process smoother and shortening the installation time, thereby solving the problems of low construction efficiency and low turnover rate during the installation process.

[0039] In this embodiment, please refer to Figure 1 and Figure 4 The inclined angle of the guardrail slot 2 is 30~60°. This angle provides suitable guidance for the insertion of the guardrail panel 3. The inclined angle of the guardrail slot 2 allows the guardrail panel 3 to utilize its own weight during insertion. During installation, the worker only needs to align one end of the guardrail panel 3 with the higher end of the guardrail slot 2 and guide it slightly; the guardrail panel 3 will then slide into the slot under its own weight. The inclined angle of the guardrail slot 2 (30~60°) makes the contact between the guardrail panel 3 and the guardrail slot 2 more conducive to dispersing lateral forces.

[0040] In this embodiment, please refer to Figure 1 and Figure 4 The guardrail slot 2 is inclined at an angle of 45°. The 45° inclination angle of the guardrail slot 2 provides a favorable guide for the insertion of the guardrail plate 3, facilitating the quick insertion of the guardrail, and also increases the structural stability and safety.

[0041] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The connector 4 includes a screw head 41, a screw rod 42, and a nut 43. The screw head 41 is perpendicular to and fixedly connected to one end of the screw rod 42. The screw head 41 is located within the horizontal portion of the through-groove 6, which has a T-shaped cross-section, and is slidably fitted. The screw rod 42 passes through the vertical portion of the through-groove 6 and the U-shaped through-groove, and is threadedly fitted to the nut 43. During operation, the screw head 41 is inserted into one end of the through-groove 6, and the screw rod 42 slides within the groove. After determining its position, the screw rod 42 passes through the U-shaped through-groove and is threadedly fitted to the nut 43. The threaded connection provides strong axial tensile force, tightly connecting the limiting moving plate 5 and the guardrail arm 1 together, ensuring a firm connection in the vertical direction. The threaded connection allows for detachable connection, facilitating disassembly and relocation.

[0042] In this embodiment, please refer to Figure 4 The width of the horizontal portion of the through groove 6, which has a T-shaped cross-section, is greater than the diameter of the screw head 41, making it easier to install and disassemble and enhancing sliding flexibility.

[0043] In this embodiment, please refer to Figure 4The screw head 41 is round, hexagonal, or square in shape.

[0044] In this embodiment, please refer to Figure 1 It also includes reflective strips 7, which are affixed to the side of the stone block 8 facing pedestrians or the driveway via release paper. The reflective strips 7 on the stone block 8 can alert pedestrians and vehicles to the construction area at night, serving a warning function, especially in low-light conditions, where the reflective strips 7 can improve visibility.

[0045] Working principle: According to construction requirements, stone piers 8 are arranged sequentially. The screw head 41 is inserted into one end of the through groove 6, and the screw rod 42 slides in the groove of the through groove 6. After determining the position, the screw rod 42 passes through the U-shaped through groove and engages with the nut 43 threadedly, tightly connecting the limiting moving plate 5 and the guardrail arm 1 to the top of the stone pier 8. This facilitates disassembly and maintenance while ensuring the firmness of the connection. The limiting moving plate 5 can be adjusted to any position on the stone pier 8 according to the length of the guardrail plate 3. The operation is convenient and simple. The guardrail arms 1 on adjacent stone piers 8 are fixed by repeating the operation. Then, multiple guardrail plates 3 are inserted into multiple guardrail slots 2 on adjacent guardrail arms 1. The inclined guardrail slot 2 design facilitates the insertion of the guardrail plates 3, making it easier to align the position during installation. The inclined angle can also play a guiding role to a certain extent, making the installation process smoother and shortening the installation time. This solves the problems of low construction efficiency, repeated drilling of stone piers which is not conducive to reuse, low turnover rate, and reduced service life of stone piers.

[0046] In summary, this utility model arranges the stone piers 8 sequentially according to construction requirements. The screw head 41 is inserted from one end of the through-groove 6, and the screw rod 42 slides within the through-groove 6. After determining the position, the screw rod 42 passes through the U-shaped groove and engages with the nut 43, tightly connecting the limiting moving plate 5 and the guardrail arm 1 to the top of the stone pier 8. This facilitates disassembly and maintenance while ensuring a secure connection. The limiting moving plate 5 can be adjusted to any position on the stone pier 8 according to the length of the guardrail plate 3, making operation convenient and simple. The guardrail arms 1 on adjacent stone piers 8 are repeatedly fixed using this method. Then, multiple guardrail plates 3 are inserted into multiple guardrail slots 2 on adjacent guardrail arms 1. The inclined guardrail slot 2 design facilitates the insertion of the guardrail plates 3, making it easier to align during installation. The inclined angle also provides guidance, making the installation process smoother and shortening installation time. This solves the problems of low construction efficiency, repeated drilling of stone piers hindering reuse, low turnover rate, and reduced lifespan of the stone piers. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
