Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision guardrail templates, and in particular to a prefabricated template for a reinforced concrete noise reduction anti-collision guardrail. Background Technology

[0002] Reinforced concrete noise reduction and crash barrier is a road barrier facility that uses reinforced concrete as its core material and has the dual functions of crash protection and traffic noise control. It is widely used along highways, urban expressways, and roads near residential areas or sensitive areas. Its main structure is made of reinforced concrete: the steel bars act as a "skeleton" to enhance the tensile and impact resistance of the structure, ensuring that the barrier is not easily broken when a vehicle hits it; the concrete acts as a "matrix" to provide compressive strength and durability, resisting long-term erosion from the natural environment (such as wind, rain, and temperature differences), resulting in a long service life. Some designs incorporate sound-absorbing materials (such as porous ceramsite or foamed concrete) on or inside the concrete surface to further enhance the noise reduction effect.

[0003] In the current use of reinforced concrete noise reduction and crash barrier formwork, demolding relies heavily on manual labor through hammering. This not only consumes a lot of manpower but also easily damages the formwork or the finished barrier, affecting the service life of the formwork and the quality of the barrier. Therefore, it is necessary to provide a prefabricated formwork for reinforced concrete noise reduction and crash barrier to solve the above technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a prefabricated template for reinforced concrete noise reduction and crashproof guardrails.

[0005] This utility model provides a prefabricated template for a reinforced concrete noise reduction and anti-collision guardrail, including a mold side plate and a demolding component. Two mold side plates are symmetrically arranged, and two horizontal bars arranged vertically are fixedly connected to the back of the mold side plates. A vertical through-hole is provided on the horizontal bar.

[0006] The demolding assembly includes a placement frame, with insertion parts at both the upper and lower parts of the placement frame, and an electric cylinder fixedly connected to the middle part of the placement frame. A push plate is fixedly connected to the telescopic end of the electric cylinder.

[0007] A through-hole is provided horizontally on the side plate of the mold. A baffle is slidably arranged in the through-hole. Two L-shaped rods are symmetrically fixedly connected to the back of the baffle. Two horizontal sliding rods are symmetrically fixedly connected to the back of the side plate of the mold. One end of each horizontal sliding rod is fixedly connected to the back of the side plate of the mold. A fixing block is fixedly connected to the other end of each horizontal sliding rod. One end of the L-shaped rod is horizontally slidably sleeved on the outside of the horizontal sliding rod.

[0008] The insertion part is provided in a one-to-one correspondence with the vertical opening, and the insertion part is inserted into the corresponding vertical opening.

[0009] Preferably, a spring is sleeved on the outer side of the slide bar, one end of the spring is fixedly connected to the back of the mold side plate, and the other end of the spring is fixedly connected to the outer wall of the L-shaped rod.

[0010] Preferably, the top of both mold side plates is fixedly connected to a top fixing ear, and two top fixing ears are symmetrically arranged. A fixing component is provided on the top fixing ears of both mold side plates.

[0011] Preferably, the fixing component includes a threaded rod, both ends of which are threaded with a first nut and a second nut, and the top fixing lug has a through hole for the threaded rod to pass through.

[0012] Preferably, the mold side plate has side connecting ears fixedly connected to both sides of its back side.

[0013] Preferably, the lower back of the mold side plate has a longitudinal through-hole for mounting.

[0014] Preferably, a switch is fixedly connected to the outer wall of the demolding assembly, and the electric cylinder is electrically connected to the switch via a wire.

[0015] Preferably, four blocks are fixedly connected to the back of the mold side plate, and the blocks abut against the back of the baffle plate.

[0016] Compared with related technologies, the prefabricated formwork for reinforced concrete noise reduction and crash protection railings provided by this utility model has the following beneficial effects:

[0017] 1. By setting up a demolding component, the insertion part is inserted into the vertical through-hole of the crossbar to achieve quick docking. The electric cylinder drives the push plate to act on the baffle, which can quickly separate the mold side plate from the formed anti-collision guardrail. There is no need for manual demolding by hammering, which reduces labor consumption. The demolding component can be removed by pulling the insertion part out of the vertical through-hole, which makes it convenient to demold the demolding component for other mold side plates. This process only requires one demolding component to adapt to multiple mold side plates, improving demolding efficiency while reducing costs.

[0018] 2. Set up a top fixing component. The horizontal threaded rod is used with the first nut and the second nut. The fixing component is used to quickly fix the two mold side plates through the top fixing ears to ensure the stability of the template structure during pouring. The side connecting ears facilitate the connection of multiple sets of reinforced concrete noise reduction and crash barrier prefabricated templates by bolts to meet the production needs of reinforced concrete noise reduction and crash barrier with different lengths.

[0019] 3. The spring is designed so that when the push plate no longer applies force to the baffle, the elastic potential energy of the spring is released, thereby causing the baffle to abut against the stop block, and the stop block to abut against the back of the baffle, thus limiting the displacement of the baffle.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] Please refer to the following: Figures 1 to 5A prefabricated formwork for a reinforced concrete noise reduction and crash barrier includes a mold side plate 1 and a demolding assembly 2. Two mold side plates 1 are symmetrically arranged, and two vertically arranged horizontal bars 3 are fixedly connected to the back of each mold side plate 1. Vertical through-holes 301 are longitudinally opened on the horizontal bars 3. The demolding assembly 2 includes a placement frame 201, with insertion parts 205 at both the upper and lower parts of the placement frame 201. The insertion parts 205 are integrally formed with the placement frame 201. An electric cylinder 203 is fixedly connected to the middle of the placement frame 201, and a pusher plate 20 is fixedly connected to the telescopic end of the electric cylinder 203. 4; A through-hole 14 is horizontally opened on the mold side plate 1, and a baffle 11 is slidably arranged inside the through-hole 14. Two L-shaped rods 5 are symmetrically fixedly connected to the back of the baffle 11, and two horizontal sliding rods 6 are symmetrically fixedly connected to the back of the mold side plate 1. One end of each horizontal sliding rod 6 is fixedly connected to the back of the mold side plate 1, and the other end of the horizontal sliding rod 6 is fixedly connected to a fixing block 8. One end of the L-shaped rod 5 is horizontally slidably sleeved on the outside of the horizontal sliding rod 6; the insertion part 205 is arranged one-to-one with the vertical through-hole 301, and the insertion part 205 is inserted into the corresponding vertical through-hole 301.

[0030] In the above, the mold side plates 1 are symmetrically arranged to form a casting space. The vertical through-hole 301 on the horizontal bar 3 cooperates with the insertion part 205 of the demolding component 2 to realize the quick assembly and disassembly of the demolding component 2 and the mold side plate 1. This makes it easy for the demolding component 2 to be used in multiple mold side plates 1. When the electric cylinder 203 drives the push plate 204 to act on the baffle 11, the L-shaped rod 5 slides along the horizontal slide bar 6, which drives the mold side plate 1 to separate from the formed anti-collision guardrail, replacing manual hammering demolding, reducing manpower consumption and avoiding damage to the template or guardrail. The fixing block 8 can limit the sliding range of the L-shaped rod 5.

[0031] Furthermore, a spring 7 is fitted on the outer side of the horizontal slide bar 6. One end of the spring 7 is fixedly connected to the back of the mold side plate 1, and the other end of the spring 7 is fixedly connected to the outer wall of the L-shaped rod 5.

[0032] In the above, after the demolding component 2 removes the pushing force on the baffle 11, the elastic potential energy of the spring 7 is released, causing the L-shaped rod 5 to slide along the horizontal slide bar 6 and reset, thereby causing the baffle 11 to return to its initial position.

[0033] Example 2

[0034] For further details, please refer to [link / reference]. Figures 1 to 6 Based on Embodiment 1, the top of both mold side plates 1 are fixedly connected to top fixing ears 13. Two top fixing ears 13 are symmetrically arranged, and fixing components 4 are provided on the top fixing ears 13 of both mold side plates 1.

[0035] In the above, the top fixing ear 13 provides an installation fulcrum for the fixing component 4. The two symmetrical mold side plates 1 can be firmly connected at the top through the fixing component 4, which prevents the top of the mold side plates 1 from opening due to lateral pressure when pouring concrete, ensuring the accuracy of the top forming size of the guardrail and improving the overall stability of the template.

[0036] Furthermore, the fixing component 4 includes a horizontal threaded rod 401, both ends of which are threaded with a first nut 402 and a second nut 403, and the top fixing lug 13 has a through hole for the horizontal threaded rod 401 to pass through.

[0037] In the above, after the horizontal threaded rod 401 passes through the through hole of the top fixing ear 13, the first nut 402 and the second nut 403 clamp the top fixing ear 13 from both sides, which can quickly realize the connection and fixation of the two mold side plates 1. By adjusting the position of the first nut 402 and the second nut 403, the distance between the two mold side plates 1 can be flexibly adjusted to adapt to the production needs of guardrails of different thicknesses and enhance the versatility of the template.

[0038] Furthermore, both sides of the back of the mold side plate 1 are fixedly connected with side connecting ears 9, and the side connecting ears 9 are horizontally through-holes for bolts to pass through.

[0039] In the above, the through holes on the side connecting ears 9 facilitate the passage of bolts, allowing two adjacent sets of reinforced concrete noise reduction and crash barrier prefabricated templates to be firmly spliced ​​together through the side connecting ears 9, realizing the continuous extension of the templates, meeting the production needs of guardrails of different lengths, and enhancing the overall rigidity of the assembled templates to ensure the quality of guardrail forming.

[0040] Furthermore, a mounting slot 10 is longitudinally provided on the lower back of the mold side plate 1.

[0041] In the above, the mounting slot 10 provides a channel for fixing the template to the ground. By passing expansion screws and other fasteners through the mounting slot 10, the side plate 1 of the mold is stably fixed in the preset position, preventing the template from shifting as a whole due to the impact force or lateral pressure of the concrete during the pouring process, and ensuring the accurate shape of the guardrail during pouring.

[0042] Furthermore, a switch 202 is fixedly connected to the outer wall of the demolding assembly 2, and an electric cylinder 203 is electrically connected to the switch 202 via a wire. The switch 202 is electrically connected to an external power source via a wire.

[0043] In the above, switch 202 is used to control the extension and retraction of electric cylinder 203, making it easy for operators to get started quickly; it is connected to an external power source through a wire to provide the electric cylinder 203 with the power required for operation.

[0044] Furthermore, four blocks 12 are fixedly connected to the back of the mold side plate 1, and the blocks 12 abut against the back of the baffle plate 11.

[0045] In the above, the stop block 12 abuts against the back of the baffle 11 to restrict the sliding of the baffle 11 away from the mold side plate 1, prevent the baffle 11 from dislodging from the through hole 14 due to the excessive restoring force of the spring 7, and ensure that the baffle 11 is in an effective working position.

[0046] The working principle of the prefabricated formwork for reinforced concrete noise reduction and crash protection railing provided by this utility model is as follows:

[0047] In practical use, several sets of the prefabricated templates for reinforced concrete noise reduction and crash protection railings of this utility model are continuously placed according to the required length of the reinforced concrete noise reduction and crash protection railing. Two mold side plates 1 are placed on both sides of the steel frame used to make the reinforced concrete noise reduction and crash protection railing. Horizontal threaded rods 401 are passed through the top fixing ears 13 of the two mold side plates 1, with the first nut 402 on one side of the top fixing ear 13 and the second nut 403 on the other side. The first nut 402 and the second nut 403 are tightened, and the two top fixing ears 13 are connected by the fixing component 4, thereby assembling and fixing the two mold side plates 1. The mold side plates 1 are fixed to the ground by expansion screws or other fasteners passing through the mounting slots 10. When connecting adjacent sets, bolts are passed through the through holes on the side connecting ears 9 to fix the adjacent side connecting ears 9 together, thereby achieving the connection of the two sets of reinforced concrete noise reduction and crash protection railings of this utility model. The prefabricated templates are connected and fixed, and then concrete is poured between the two mold side plates 1. After molding, demolding is performed using a demolding component 2. One demolding component 2 can demold multiple mold side plates 1. The insertion part 205 of the demolding component 2 is inserted into the vertical through-hole 301 on the crossbar 3. Then, the electric cylinder 203 is activated by the switch 202. The extension end of the electric cylinder 203 extends and drives the push plate 204 to move closer to the baffle 11. As the extension end of the electric cylinder 203 extends, it pushes the push plate 204 to move closer to the molded crash barrier. Due to the resistance of the crash barrier, the electric cylinder 203 applies a force to the placement frame 201 in a direction away from the crash barrier. The placement frame 201 drives the crossbar 3 to move the mold side plates 1 away from the crash barrier, thereby separating the mold side plates 1 from the molded reinforced concrete noise reduction crash barrier. Then, the demolding component 2 is installed on the next mold side plate 1 that needs to be demolded in the same way.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
