Description

Technical Field

[0001] This utility model relates to the field of concrete guardrail technology, and in particular to a prefabricated concrete guardrail. Background Technology

[0002] Precast concrete guardrails are manufactured in factories using standardized molds, producing guardrail panels, bases, and other core components with steel reinforcement frames. After undergoing processes such as steam curing to ensure strength and dimensional accuracy, they are transported to the construction site and assembled and fixed using pre-embedded connectors. They have advantages such as high construction efficiency, controllable quality, environmental protection and energy saving, and strong repairability, and are widely used in various road scenarios such as highways, urban expressways, and bridges.

[0003] Currently, in existing precast concrete guardrail technology, the guardrail panels and bases typically have pre-embedded connectors, which are then secured on-site using high-strength bolts. However, during the docking process between the guardrail panels and the base, the pre-embedded connectors are prone to positional shifts due to factors such as factory prefabrication precision deviations or installation positioning errors. This makes precise alignment difficult, requiring repeated adjustments to the guardrail panels, which increases the difficulty of on-site construction and reduces assembly efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose an assembled precast concrete guardrail. By setting a sliding adjustment connection mechanism, the precise alignment of the connecting parts is achieved, which solves the problem of docking difficulties caused by the position deviation of the embedded parts. Moreover, there is no need to move the guardrail as a whole during the adjustment process, which significantly reduces the construction difficulty and improves the assembly efficiency.

[0006] To achieve the above objectives, this utility model proposes an assembled precast concrete guardrail, comprising a guardrail panel, a base, multiple first embedded parts, multiple second embedded parts, and a connecting mechanism. The multiple first embedded parts are equidistantly arranged within the base, and the multiple second embedded parts are equidistantly arranged within the guardrail panel. The guardrail panel is inserted into a pre-set groove in the base. The first embedded parts are connected to the second embedded parts via the connecting mechanism. The connecting mechanism includes a connecting component, an adjusting component, and a locking component. The connecting component is disposed on the first embedded part and connected to the adjusting component. The adjusting component is disposed on the second embedded part and moves and adjusts along the length direction of the base. The locking component is disposed within the adjusting component.

[0007] In addition, the prefabricated concrete guardrail proposed above according to this utility model may also have the following additional technical features: Specifically, the connecting assembly includes an L-shaped plate, a locking nut, a connecting plate, and a connecting bolt, wherein the threaded end of the connecting bolt passes through the connecting plate and the L-shaped plate respectively, and is connected to the locking nut.

[0008] Specifically, the adjustment assembly includes a fixed plate, multiple ear plates, multiple adjustment seats, and a guide rail. The multiple ear plates are symmetrically arranged on the guide rail and connected to the fixed plate, and the multiple adjustment seats are slidably arranged within the guide rail.

[0009] Specifically, the locking assembly includes two locking bolts, a locking block, and a friction plate. The two locking bolts are symmetrically threaded within the adjusting seat, the friction plate is disposed within the guide rail, and the two locking blocks are symmetrically slidably disposed within the adjusting seat and in contact with the friction plate. The threaded end of the locking bolt abuts against the locking block.

[0010] Specifically, the base has equidistantly arranged transverse limiting seats inside, and the bottom of the guardrail has equidistantly arranged transverse grooves, with the transverse limiting seats engaging within the transverse grooves.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention, by setting an adjustment component and utilizing the sliding adjustment function of the adjustment seat, can flexibly adjust the position of the L-shaped plate, enabling the L-shaped plate to precisely align with the connecting plate. This solves the problem of inaccurate alignment of pre-embedded connecting parts due to deviations in prefabrication precision or installation positioning errors. Moreover, during the adjustment and alignment process, there is no need to move the guardrail panel as a whole, significantly reducing construction difficulty and improving assembly efficiency. At the same time, in conjunction with the locking component, the adjustment seat can be firmly fixed after it is in place, preventing the guardrail panel from loosening during use, and further enhancing the stability and reliability of the connection between the guardrail panel and the base.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of the present invention are described in detail below, examples of which 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 intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The prefabricated concrete guardrail of this utility model embodiment will be described below with reference to the accompanying drawings.

[0017] like Figures 1-5 As shown in the figure, an assembly-type precast concrete guardrail according to an embodiment of the present utility model includes a guardrail plate 1, a base 2, a plurality of first embedded parts 3, a plurality of second embedded parts 4, and a connecting mechanism. The plurality of first embedded parts 3 are equidistantly arranged in the base 2, and the plurality of second embedded parts 4 are equidistantly arranged in the guardrail plate 1. The guardrail plate 1 is inserted into a preset groove in the base 2, and the first embedded parts 3 are connected to the second embedded parts 4 through the connecting mechanism.

[0018] It should be noted that the surfaces of the first embedded part 3 and the second embedded part 4 are both treated with rust prevention. The first embedded part 3 is embedded in the base 2, and the second embedded part 4 is embedded in the guardrail 1.

[0019] The base 2 has equidistantly arranged transverse limiting seats 8 inside, and the bottom of the guardrail 1 has equidistantly arranged transverse grooves 9, with the transverse limiting seats 8 snapped into the transverse grooves 9.

[0020] It is understandable that the base 2 has a preset groove inside, and the lateral limiting seat 8 is set in the preset groove. When the guardrail 1 is inserted into the preset groove of the base 2, the lateral limiting seat 8 is embedded in the lateral groove 9, which plays a lateral limiting role on the guardrail 1 and prevents the guardrail 1 from being displaced in the horizontal direction.

[0021] The connecting mechanism includes a connecting component 5, an adjusting component 6, and a locking component 7. The connecting component 5 is disposed on the first embedded part 3 and connected to the adjusting component 6. The adjusting component 6 is disposed on the second embedded part 4 and moves and adjusts along the length direction of the base 2. The locking component 7 is disposed inside the adjusting component 6.

[0022] It should be noted that the connecting component 5 and the first embedded part 3 are connected by welding to ensure the stability of the connection. The locking component 7 is used to lock and fix the adjusting component 6 after it is moved to the appropriate position to prevent it from loosening during use.

[0023] Understandably, by setting up a connecting mechanism, the position of the connecting component 5 can be flexibly adjusted according to the position of the guardrail 1 and the base 2. This can solve the problem of the pre-embedded connecting parts being misaligned due to prefabrication accuracy deviation or installation positioning error, eliminating the need to adjust the position of the guardrail 1, reducing construction difficulty and improving assembly efficiency.

[0024] In one embodiment of this utility model, such as Figures 3-4 As shown, the connecting assembly 5 includes an L-shaped plate 51, a locking nut 52, a connecting plate 53, and a connecting bolt 54. The threaded end of the connecting bolt 54 passes through the connecting plate 53 and the L-shaped plate 51, respectively, and is connected to the locking nut 52.

[0025] It should be noted that the L-shaped plate 51 is welded to the adjusting seat 64, and the connecting plate 53 is welded to the first embedded part 3. Both the L-shaped plate 51 and the connecting plate 53 have connecting through holes. The L-shaped plate 51 and the connecting plate 53 can be fixedly connected by the cooperation of the connecting bolt 54 and the locking nut 52.

[0026] It is understandable that the connection assembly 5, consisting of L-shaped plate 51, locking nut 52, connecting plate 53 and connecting bolt 54, achieves a stable connection between the first embedded part 3 and the adjusting assembly 6.

[0027] In one embodiment of this utility model, such as Figures 3-4 As shown, the adjustment assembly 6 includes a fixed plate 62, multiple ear plates 63, multiple adjustment seats 64 and a guide rail 65. The multiple ear plates 63 are symmetrically arranged on the guide rail 65 and connected to the fixed plate 62. The multiple adjustment seats 64 are all slidably arranged in the guide rail 65.

[0028] It should be noted that the ear plate 63 is welded to the guide rail 65, the fixing plate 62 is welded to the second embedded part 4, the ear plate 63 is connected to the fixing plate 62 by bolts, the adjusting seat 64 has a T-shaped cross section, slides in the guide rail 65, and is welded to the L-shaped plate 51.

[0029] Understandably, when the first embedded part 3 and the second embedded part 4 are misaligned due to prefabrication or installation errors, the L-shaped plate 54 and the connecting plate 53 are difficult to align precisely. In this case, by pushing the adjusting seat 64 to slide within the guide rail 65, the L-shaped plate 51 can be moved to accurately align with the connecting plate 53 on the first embedded part 3. Then, the two are securely connected by the connecting bolt 54 and the locking nut 52. This process does not require the overall displacement of the guardrail plate 1. Precise alignment can be achieved simply by adjusting the sliding of the adjusting component 6, effectively solving the problem of inconvenient connection caused by prefabrication or installation errors.

[0030] In one embodiment of this utility model, such as Figure 5 As shown, the locking assembly 7 includes two locking bolts 71, a locking block 72, and a friction plate 73. The two locking bolts 71 are symmetrically threaded in the adjusting seat 64, the friction plate 73 is disposed in the guide rail 65, and the two locking blocks 72 are symmetrically slidably disposed in the adjusting seat 64 and fit against the friction plate 73. The threaded end of the locking bolt 71 abuts against the locking block 72.

[0031] It should be noted that the friction plate 73 is made of rubber and has anti-slip texture on its surface to increase the friction between it and the locking block 72. The adjusting seat 64 has a limit groove inside, and the locking block 72 slides in the limit groove so that the locking block 72 can only move along the axial direction of the locking bolt 71.

[0032] Understandably, when the adjusting seat 64 slides to the appropriate position within the guide rail 65, the locking bolt 71 is rotated. The threaded end of the locking bolt 71 gradually moves inward toward the adjusting seat 64 and abuts against the locking block 72, pushing the locking block 72 to fit tightly against the friction plate 73. Under the action of friction, the adjusting seat 64 is fixed within the guide rail 65 and cannot continue to slide, thus achieving the locking and fixing of the adjusting component 6, preventing the adjusting component 6 from loosening during use, and ensuring the stability of the connection between the guardrail plate 1 and the base 2.

[0033] In practical applications, when assembling the guardrail 1 and the base 2, the guardrail 1 is first inserted into the preset slot of the base 2. Due to possible precision deviations or installation positioning errors during the prefabrication process, there will be a positional offset between the first embedded part 3 and the second embedded part 4, which will cause the L-shaped plate 51 to be unable to be precisely aligned with the connecting plate 53.

[0034] At this time, by pushing the adjusting seat 64 to slide in the guide rail 65, the adjusting seat 64 drives the L-shaped plate 51 to move, so that the L-shaped plate 51 is aligned with the connecting plate 53 on the first embedded part 3. When the L-shaped plate 51 and the connecting plate 53 are aligned, the threaded end of the connecting bolt 54 is passed through the connecting through hole on the connecting plate 53 and the L-shaped plate 51 respectively, and the locking nut 52 is used to tighten it, thereby realizing the stable connection between the first embedded part 3 and the adjusting assembly 6, and completing the initial connection between the guardrail plate 1 and the base 2.

[0035] After the initial connection is completed, the locking bolt 71 is rotated, and the threaded end of the locking bolt 71 abuts against the locking block 72, pushing the locking block 72 to fit tightly against the friction plate 73. Under the action of friction, the adjusting seat 64 is fixed in the guide rail 65 and cannot continue to slide, thus ensuring the stability of the connection between the guardrail plate 1 and the base 2.

[0036] In summary, the prefabricated concrete guardrail of this utility model embodiment, by setting an adjustment component and utilizing the sliding adjustment function of the adjustment seat, can flexibly adjust the position of the L-shaped plate, so that the L-shaped plate can be precisely aligned with the connecting plate. This solves the problem of inaccurate alignment of the embedded connecting parts due to deviations in prefabrication accuracy or installation positioning errors. Moreover, it eliminates the need for overall displacement of the guardrail panel, significantly reducing construction difficulty and improving assembly efficiency. At the same time, with the locking component, the adjustment seat can be firmly fixed after it is in place, preventing the guardrail panel from loosening during use, and further enhancing the stability and reliability of the connection between the guardrail panel and the base.
