Description

Technical Field

[0001] This utility model belongs to the field of anti-collision wall technology, specifically, it relates to a prefabricated anti-collision wall template. Background Technology

[0002] Traditional cast-in-place concrete crash barriers involve time-consuming and labor-intensive processes such as erecting formwork on-site and then pouring concrete, and it is extremely dangerous for workers to work at heights. Using prefabricated concrete structures for bridge crash barriers can reduce the dangers of on-site operations and improve work efficiency.

[0003] A document with publication number CN221192973U discloses a prefabricated concrete permanent formwork for bridge crash barriers, belonging to the technical field of prefabricated bridge crash barriers. The formwork includes an inner and outer permanent concrete formwork arranged opposite each other, with a gap between them. A bottom support assembly includes a first base fixed to the bottom of one side of the inner permanent concrete formwork and a second base fixed to the bottom of one side of the outer permanent concrete formwork, located between the inner and outer permanent concrete formworks. Compared to on-site casting, this device significantly reduces on-site formwork time and manpower, ensuring construction safety. Furthermore, compared to traditional prefabricated crash barriers, the prefabricated formwork is lighter, smaller, easier to transport, and has a stronger connection and adhesion to the bridge deck, resulting in better impact resistance.

[0004] The above-mentioned device only improves the combination of the crash barrier template, but the template still needs to be disassembled after pouring, which increases the processing steps and reduces work efficiency. Moreover, the existing concrete crash barrier, after being poured, only prevents vehicles from running out of the wall while driving, but the force of the vehicle directly hitting the crash barrier is directly reflected on the vehicle, threatening the safety of the people inside the vehicle.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the technical problems of anti-collision wall templates, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A prefabricated crash barrier formwork includes a base with an installation position; and a modular assembly for rapid casting of the crash barrier. The modular assembly includes a first template, a second template, a first connecting plate, and a second connecting plate. The first template and the second template are connected to the base by fasteners. The ends of the first template and the second template have openings. The second connecting plate is set on the second template, and the first connecting plate is set on the first template. The corresponding second connecting plate is connected to the first template and the second template by fasteners.

[0008] In a preferred embodiment of the present invention, a connection port is provided at one end of the first template and the second template, and an extension block is provided at the other end of the first template and the second template. The cross-sections of the connection port and the extension block are both along the shape of the first template and the second template, and the corresponding connection port and the extension block are engaged.

[0009] In a preferred embodiment of the present invention, each of the first and second connecting plates is provided with an array of contact plates, and each contact plate is fixedly connected to the corresponding second connecting plate.

[0010] In a preferred embodiment of this utility model, each of the contact plates is wavy in shape, and the size of each second contact plate is smaller than the corresponding first template and second template.

[0011] In a preferred embodiment of the present invention, an abutment plate is provided on the first template, the cross section of the abutment plate is along the shape of the first template, and an energy-absorbing component is provided between the first template and the abutment plate.

[0012] In a preferred embodiment of the present invention, the energy-absorbing component includes an energy-absorbing block and a mounting block. Each mounting block is connected to the first template by fasteners, and the corresponding energy-absorbing block is fixedly connected to the mounting block.

[0013] In a preferred embodiment of the present invention, each of the energy-absorbing blocks is corrugated in shape, each energy-absorbing block is made of high-strength steel, and each energy-absorbing block is connected to the abutment plate by fasteners.

[0014] In a preferred embodiment of the present invention, a connecting block is provided in the opening between the first template and the second template. The connecting block engages with the first template and the second template, and the first template, the second template, and the connecting block are connected by fasteners.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This prefabricated anti-collision wall formwork does not require the removal of the first and second formworks after pouring. The connecting blocks are embedded in the formwork openings and fixed with bolts to secure the first and second formworks. The energy-absorbing components and the abutment plates work together to enhance the impact resistance of the formwork and allow for the reuse of the formwork.

[0017] 2. This type of prefabricated crash barrier formwork uses a matching interlocking structure for the connection port and extension block, enabling rapid positioning and splicing between formworks and reducing manual adjustment time; through the interlocking design, it ensures smooth lines after the formwork is spliced ​​and avoids concrete leakage.

[0018] 3. This prefabricated crash barrier formwork increases the contact area between the first and second connecting plates and the concrete by using a first connecting plate, a second connecting plate, and a contact plate. This prevents cracks from forming in the internal concrete, allowing the device to detach from the concrete crash barrier. Simultaneously, the weight of the concrete crash barrier secures the formwork to the outside, and the formwork protects the internal concrete crash barrier from damage caused by the external environment.

[0019] 4. This type of prefabricated crash barrier formwork features corrugated energy-absorbing blocks made of high-strength steel, which absorb external impact forces and protect the stability of the formwork structure. The installation blocks fix the energy-absorbing blocks, enhancing the overall resistance to deformation. When subjected to external impact, the energy-absorbing blocks buffer energy through deformation, preventing formwork damage or concrete cracking, and preventing vehicles from directly impacting the crash barrier and having the force directly react on the vehicle, thus avoiding a threat to the safety of the people inside the vehicle.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] Please see Figure 1-5A prefabricated crash barrier formwork includes a base with installation positions; and a modular assembly for rapid casting of the crash barrier. The modular assembly includes a first template 1, a second template 2, a first connecting plate 11, and a second connecting plate 21. The first template 1 and the second template 2 are connected to the base via fasteners, including but not limited to bolts. Openings are provided at the ends of the first template 1 and the second template 2. The second connecting plate 21 is mounted on the second template 2, and the first connecting plate 11 is mounted on the first template 1. The corresponding second connecting plate 21 is connected to the first template 1 and the second template 2 via fasteners. The plate 2 is connected, and the fasteners include but are not limited to bolts. The base is fixed to the bridge deck or the ground by bolts. The first template 1 and the second template 2 are quickly spliced ​​by the engagement of the connecting port 3 and the extension block 31. The first connecting plate 11 and the second connecting plate 21 are connected by a corrugated contact plate 22 to enhance the connection stability and form a continuous pouring space. After pouring, it is not necessary to remove the first template 1 and the second template 2. The connecting block 5 is embedded in the template opening and fixed by bolts to fix the first template 1 and the second template 2. The energy-absorbing component and the abutment plate 4 work together to enhance the impact resistance of the template and allow the template to be reused.

[0030] The first template 1 and the second template 2 are provided with a connection port 3 at one end and an extension block 31 at the other end. The cross-sections of the connection port 3 and the extension block 31 are both along the shape of the first template 1 and the second template 2. The corresponding connection port 3 and the extension block 31 are engaged. The connection port 3 and the extension block 31 adopt a matching engagement structure to realize quick positioning and splicing between templates and reduce manual adjustment time. Through the interlocking design, the line of the template after splicing is ensured to be smooth and concrete leakage is avoided.

[0031] Each of the first connecting plates 11 and the second connecting plates 21 is provided with an array of contact plates 22. Each contact plate 22 is fixedly connected to the corresponding second connecting plate 21. Each contact plate 22 is wavy in shape, and the size of each second connecting plate 21 is smaller than the corresponding first template 1 and second template 2. The first connecting plates 11 and the second connecting plates 21 are located in the middle of the casting workpiece. After the concrete is poured, the concrete fixes the first connecting plates 11 and the second connecting plates 21 inside. After the first connecting plates 11 and the second connecting plates 21 are fixed inside, the position of the template is fixed. The template is fixed outside the concrete crash barrier to protect the internal concrete crash barrier. The contact plates 22 increase the contact area between the first connecting plates 11 and the second connecting plates 21 and the concrete, preventing the device from detaching from the concrete crash barrier after cracks appear between them. At the same time, the weight of the concrete crash barrier fixes the template outside and protects the internal concrete crash barrier from damage by the external environment.

[0032] The first template 1 is provided with an abutment plate 4. The cross-section of the abutment plate 4 follows the shape of the first template 1. An energy-absorbing component is provided between the first template 1 and the abutment plate 4. The energy-absorbing component includes an energy-absorbing block 41 and an installation block 42. Each installation block 42 is connected to the first template 1 by fasteners. The corresponding energy-absorbing block 41 is fixedly connected to the installation block 42. The fasteners include, but are not limited to, bolts. Each energy-absorbing block 41 is corrugated in shape and is made of high-strength steel. Each energy-absorbing block 41 is connected to the abutment plate 4 by fasteners. The corrugated energy-absorbing block 41 is made of high-strength steel to absorb external impact and protect the stability of the template structure. The installation block 42 fixes the energy-absorbing block and enhances the overall resistance to deformation. When subjected to external impact, the energy-absorbing block buffers energy through deformation to avoid template damage or concrete cracking, and to prevent vehicles from directly impacting the crash barrier and having the force directly react on the vehicle, thus threatening the safety of the people inside the vehicle.

[0033] The opening between the first template 1 and the second template 2 is provided with a connecting block 5. The connecting block 5 is engaged with the first template 1 and the second template 2, and the first template 1, the second template 2 and the connecting block 5 are connected by fasteners, including but not limited to bolts. The connecting block 5 fills the opening between the first template 1 and the second template 2 to form a complete casting cavity. By engaging and fixing with bolts, the airtightness of the template joints after the casting process is ensured, and the flatness of the anti-collision wall surface is improved.

[0034] Working principle: The base is fixed to the bridge deck or ground with bolts. The first template 1 and the second template 2 are quickly spliced ​​together by the engagement of the connecting port 3 and the extension block 31. The first connecting plate 11 and the second connecting plate 21 are connected by a corrugated contact plate 22 to enhance the connection stability and form a continuous pouring space. After pouring, the first template 1 and the second template 2 do not need to be removed. The connecting block 5 is embedded in the template opening and fixed with bolts to fix the first template 1 and the second template 2. The energy-absorbing component and the abutment plate 4 work together to enhance the impact resistance of the template and reuse the template. The connecting port 3 and the extension block 31 adopt a matching interlocking structure to realize the quick positioning and splicing between templates and reduce the time for manual adjustment. The concave and convex interlocking design ensures a smooth line after the template is spliced ​​and avoids concrete leakage. The first connecting plate 11 and the second connecting plate 21 are in the middle of the poured workpiece. After the concrete is poured, the concrete fixes the first connecting plate 11 and the second connecting plate 21 inside. After the first connecting plate 11 and the second connecting plate 21 are fixed inside, the position of the template is fixed and the template is fixed in the concrete. Outside the concrete crash barrier, the device protects the internal concrete crash barrier. Contact plate 22 increases the contact area between the first connecting plate 11 and the second connecting plate 21 and the concrete, preventing cracks in the internal concrete. The device then detaches from the concrete crash barrier, using the weight of the concrete crash barrier to fix the formwork externally and protect the internal concrete crash barrier from external environmental damage. The corrugated energy-absorbing block 41, made of high-strength steel, absorbs external impact and protects the formwork structure's stability. Installation block 42 fixes the energy-absorbing block, enhancing overall deformation resistance. When subjected to external impact, the energy-absorbing block buffers energy through deformation, preventing formwork damage or concrete cracking, and preventing direct impact from vehicles onto the crash barrier, thus avoiding threats to the safety of occupants. Connecting block 5 fills the opening between the first formwork 1 and the second formwork 2, forming a complete pouring cavity. Through locking and bolt fixing, the sealing of the formwork joints after pouring is ensured, improving the surface flatness of the crash barrier.
