Description

Technical Field

[0001] The utility model relates to the field of casting tools, and more specifically, to a casting tool for concrete guardrails. Background Art

[0002] The concrete anti-collision guardrail is a kind of guardrail that can block collision vehicles with collision energy less than or equal to its design energy and play a role in dissipating energy and guiding the driving direction. At present, the construction site is mainly built by in-situ casting, and the height of the guardrail is mostly about 1.2 m. Before casting, two opposite templates are fixedly arranged on the bridge side or the roadside (the template close to the bridge deck is the inner template, and the side far from the bridge deck is the outer template). When pouring concrete, the discharge port of the tanker is directly placed above the pouring port formed by the two templates, and the concrete is poured between the two templates. Since the discharge chute of the tanker is short, the tanker needs to be as close as possible to the inner template. When moving after getting close, the tanker is likely to scrape the supporting components of the inner template of the guardrail, resulting in the displacement or misalignment of the inner template, affecting the alignment and construction quality. Moreover, during the process of concrete entering the mold, due to the large inclination of the discharge chute of the tanker, the speed of the concrete poured between the templates is fast, which is easy to splash out and pollute the template and the bridge deck, affecting the appearance, causing waste of concrete, and the later cleaning is very troublesome, and the time invested is also relatively increased. Summary of the Utility Model

[0003] The utility model aims to overcome the defects of the above-mentioned prior art and provides a casting tool for concrete guardrails, which is used to solve the technical problems that the inclination of the discharge chute of the tanker is large, the speed of the concrete poured between the templates is fast, it is easy to splash out and pollute the template and the bridge deck, affecting the appearance, causing waste of concrete, and the later cleaning is troublesome, and the time invested is also relatively increased.

[0004] The technical solution adopted by the utility model is that a casting tool for concrete guardrails includes a chute, a stop beam and support legs; the chute has a feeding end and a loading end, a stop beam is fixedly arranged at the bottom of the feeding end of the chute, support legs are installed at the bottom of the loading end of the chute, the bottom of the port of the feeding end of the chute is lapped with the inner edge of the top of the inner template, the loading end of the chute is supported by the support legs, the loading end of the chute is higher than the feeding end of the chute, and the side surface of the stop beam is in contact with the outer side surface of the inner template.

[0005] When in use, the feeding end of the chute is supported by the supporting legs, and the feeding end of the chute is arranged at the top of the inner formwork and is connected to the port formed by the two formworks; the chute has a certain length, and the transition of the chute can keep the concrete tanker away from the inner formwork, which can effectively prevent the tanker from scratching the supporting components of the inner formwork, and avoid affecting the line shape and construction quality; when pouring, the concrete output by the tanker first flows to the feeding end of the chute, and then flows to the feeding end through the chute, and then enters between the two formworks. Its inclination is smaller than that of the tanker unloading chute, and the flow speed of the concrete is reduced. The bottom of the feeding end port of the chute overlaps the inner edge of the top of the inner formwork, which can minimize the falling height of the concrete, effectively prevent the falling concrete from splashing and spilling out to pollute the formwork and the bridge deck, effectively improve the aesthetics, avoid concrete waste, and at the same time, no need for later cleaning, which can effectively reduce the time invested.

[0006] Furthermore, the invention further comprises a reinforcing rod, one end of which is fixedly connected to the bottom of the chute discharge end, and the other end of which is fixedly connected to the support leg. The reinforcing rod, the support leg, and the chute bottom form a triangular structure. The reinforcing rod improves the structural strength and supporting capacity of the concrete guardrail casting tool, thereby enabling it to load more concrete and improving its stability.

[0007] Furthermore, a transverse beam is fixed to the bottom of the chute feed end, and the support legs are fixedly connected to the transverse beam and the chute bottom, respectively. The transverse beam is mainly used to increase the structural strength of the chute feed end, thereby improving its load capacity, and at the same time, it strengthens the connection between the support legs and the chute bottom, preventing fracture at the connection between the support legs and the chute.

[0008] Furthermore, the support legs are telescopic rods, by which the length of the support legs can be adjusted, thereby changing the inclination of the chute, so as to facilitate on-site adaptive adjustment according to the height of the inner formwork. By adjustment, it can be used for pouring concrete guardrails of different heights, which can effectively expand its applicability.

[0009] Furthermore, the support leg includes a sleeve, a locking piece and an insertion rod. One end of the sleeve is fixedly connected to the bottom of the feeding end of the chute, and the insertion rod is plugged into the other end of the sleeve. The locking piece is arranged between the sleeve and the insertion rod for fixedly connecting the sleeve and the insertion rod.

[0010] Furthermore, the locking member includes a vertical portion, a locking tooth, and a stop portion. The vertical portion has two opposite side surfaces, namely a first side surface and a second side surface. The locking teeth are provided on the first side surface, and the stop portion is fixed on the second side surface. The locking teeth are used to engage the rod body, and the stop portion is used to stop the other end of the sleeve. The rod is inserted into the sleeve, the length of the rod is adjusted according to the required height, the locking teeth are pressed and engaged into the rod body, and the rod is inserted into the other end of the sleeve together with the rod. After the vertical portion is inserted into the sleeve, the other end of the sleeve abuts against the stop portion, and the rod and sleeve are locked. Under the action of the gravity of the chute, the rod will not fall out of the sleeve. When removing the rod, it is only necessary to pull out the rod, and the locking member will be pulled out together, thereby releasing the lock. This method is fast in insertion and removal.

[0011] Furthermore, the first side surface of the vertical portion is a flat surface, the second side surface of the vertical portion is an inclined surface, and the thickness of the vertical portion gradually increases as it approaches the stop portion. The thickness of the end of the vertical portion away from the stop portion is relatively small, allowing it to be easily inserted into the gap between the sleeve and the insertion rod, making it easier to insert the sleeve.

[0012] Furthermore, the thickness of the vertical portion at the stopper is equal to the gap between the sleeve and the insertion rod. This allows for a more secure lock during insertion and ease of removal. If the gap is smaller than 0.5 mm, the lock is insufficient, while if it is larger, removal becomes difficult. This makes assembly and disassembly easier, effectively improving the user experience.

[0013] Furthermore, the locking teeth are oblique teeth with the tooth tips facing the stopper, which have a stronger bite ability and can connect the rod and the sleeve more firmly under the support of gravity.

[0014] Furthermore, the chute includes a bottom plate, side plates, and reinforcing ribs. Two side plates are provided parallel to the bottom plate and are fixedly connected to the bottom plate. Reinforcing ribs are fixed between the side plates and the bottom plate. The reinforcing ribs are used to increase the connection strength between the side plates and the bottom plate, thereby improving the load capacity of the chute.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the chute has a certain length, and the transition of the chute can keep the concrete tanker away from the inner formwork, which can effectively prevent the tanker from scratching the supporting components of the inner formwork, avoiding affecting the line shape and construction quality; during pouring, the concrete output by the tanker first flows to the loading end of the chute, and then flows to the unloading end through the chute, and then enters between the two formworks. Its inclination is smaller than that of the tanker unloading chute, and the concrete flow speed is reduced. The bottom of the unloading end port of the chute overlaps the inner edge of the top of the inner formwork, which can minimize the falling height of the concrete, effectively prevent the falling concrete from splashing and spilling out to pollute the formwork and the bridge deck, avoid concrete waste, effectively improve the aesthetics, and at the same time, no need for later cleaning, which can effectively reduce the time invested.

Detailed Description of the Embodiments

[0021] The drawings of the present utility model are only for illustrative purposes and should not be construed as a limitation to the present utility model. For better illustrating the following embodiments, some components in the drawings may be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0022] Embodiment 1

[0023] As Figure 1 and 2 shown, this solution discloses a concrete guardrail casting tool, including a chute 1, a stop beam 2 and a support leg 3; the chute 1 has a blanking end and a feeding end, a stop beam 2 is fixedly provided at the bottom of the blanking end of the chute 1, a support leg 3 is installed at the bottom of the feeding end of the chute 1, the bottom of the port of the blanking end of the chute 1 is lapped with the inner edge of the top end of the inner formwork, the feeding end of the chute 1 is supported by the support leg 3, the feeding end of the chute 1 is higher than the blanking end of the chute 1, and the side of the stop beam 2 is in contact with the outer side of the inner formwork; the support leg 3 is perpendicular to the bottom of the chute 1, with more reasonable force application and capable of providing a greater supporting force.

[0024] It further includes a strengthening rod 4, one end of the strengthening rod 4 is fixedly connected to the bottom of the blanking end of the chute 1, the other end of the strengthening rod 4 is fixedly connected to the support leg 3, and the strengthening rod 4 forms a triangular structure with the support leg 3 and the bottom of the chute 1. The structural strength and supporting ability of this concrete guardrail casting tool can be improved through the strengthening rod 4, so that it can carry more concrete and its stability is relatively increased.

[0025] At the bottom of the feeding end of the chute 1, a transverse beam 5 is fixed, and the support legs 3 are respectively fixedly connected to the transverse beam 5 and the bottom of the chute 1. The transverse beam 5 is mainly used to improve the structural strength of the feeding end of the chute 1, thereby improving its load-bearing capacity. At the same time, it improves the connection strength between the support leg 3 and the bottom of the chute 1, preventing the connection between the support leg 3 and the chute 1 from breaking.

[0026] The chute 1 includes a bottom plate 12, side plates 13 and reinforcing ribs 14. There are two side plates 13 arranged in parallel on the bottom plate 12 and are respectively fixedly connected to the bottom plate 12. Reinforcing ribs 14 are fixedly arranged between the side plates 13 and the bottom plate 12. The reinforcing ribs 14 are used to improve the connection strength between the side plates 13 and the bottom plate 12, thereby improving the load-bearing capacity of the chute 1; the support legs 3, the transverse beam 5, and the stop beam 2 are all fixed on the bottom plate 12. In this solution, the reinforcing rod 4 can also be fixedly connected to the stop beam 2, or can also be fixedly connected to both the bottom plate 12 and the stop beam 2 at the same time.

[0027] In this solution, the stop beam 2, the transverse beam 5, the reinforcing rod 4, the support legs 3 and the reinforcing ribs 14 can all be made of wooden squares, and the bottom plate 12 and the side plates 13 can be made of bamboo plywood. Wooden squares and bamboo plywood are common materials at the construction site. In this way, it is more convenient to directly obtain materials from the casting construction site for on-site production, and the bottom plate 12, the side plates 13, the reinforcing ribs 14, the support legs 3, etc. can all be quickly connected and assembled by using nail guns or nails, which is more convenient for production.

[0028] Embodiment 2

[0029] As Figure 3 and 4 , the difference between this embodiment and Embodiment 1 is that in this embodiment, the support leg 3 is a telescopic rod. The length of the support leg 3 can be adjusted through the telescopic rod, thereby changing the inclination of the chute 1, so as to be adaptively adjusted according to the formwork height on site. Through adjustment, it can be applied to the casting of concrete guardrails with different heights, effectively improving its applicable range. The telescopic rod can adopt the telescopic rod commonly used in the prior art.

[0030] As a kind of telescopic rod, it can be a sleeve 6, a locking member 7 and a plug rod 8. One end of the sleeve 6 is fixedly connected to the bottom of the feeding end of the chute 1, the plug rod 8 is inserted into the other end of the sleeve 6, and the locking member 7 is arranged between the sleeve 6 and the plug rod 8 for fixedly connecting the sleeve 6 and the plug rod 8.

[0031] The locking member 7 includes a vertical portion 9, a locking tooth 10 and a stop portion 11. The vertical portion 9 has two opposite side surfaces, namely a first side surface and a second side surface. The locking teeth 10 are provided on the first side surface, and the stop portion 11 is fixed on the second side surface. The locking teeth 10 are used to engage the rod body of the insertion rod 8, and the stop portion 11 is used to stop the other end port of the sleeve 6. The rod 8 is inserted into the sleeve 6, and the length of the rod 8 is adjusted according to the required height. The locking tooth 10 is pressed and engaged into the rod body of the rod 8, and the other end of the sleeve 6 is inserted together with the rod 8. At the same time, the vertical part 9 is also inserted into the sleeve 6. The other end of the sleeve 6 is against the stop part 11, and the rod 8 and the sleeve 6 are locked. When in use, under the action of the gravity of the chute 1, the rod 8 will not fall out of the sleeve 6; when taking it out, just pull out the rod 8, and the locking piece 7 will be taken out together to release the lock. This method has a fast insertion and removal speed; the sleeve 6 can use the square steel pipe at the construction site, and the rod 8 can use the wooden square at the construction site. The wooden square and square steel pipe can be made on site at the construction site, which is more convenient to use and has low cost; one locking piece 7 can be provided, or two can be provided on two opposite sides of the rod 8.

[0032] The first side surface of the vertical portion 9 is flat, while the second side surface of the vertical portion 9 is inclined. The thickness of the vertical portion 9 gradually increases as it approaches the stopper 11. The end of the vertical portion 9 farther from the stopper 11 is relatively thin, allowing it to be easily inserted into the gap between the sleeve 6 and the insertion rod 8, making it easier to insert the sleeve 6.

[0033] The thickness of the vertical portion 9 at the stopper 11 is equal to the gap between the sleeve 6 and the insertion rod 8. This makes the locking more secure during insertion and easier to remove. If it is smaller than this, the locking is not secure enough, and if it is larger than this, it is difficult to remove. This makes it easier to disassemble and assemble, which can effectively improve the user experience.

[0034] The locking teeth 10 are oblique teeth with the tooth tips facing the stopper 11. The oblique teeth have a stronger bite ability and can connect the insertion rod 8 and the sleeve 6 more firmly under the support of gravity.

[0035] During use, first select the length of the insertion rod 8 according to the height of the template. Then insert the insertion rod 8 together with the locking member 10 into the sleeve 6 to lock the insertion rod 8 and the sleeve 6. The feeding end of the chute 1 is supported by the support legs 3. The feeding end of the chute 1 is higher than the discharging end of the chute 1. The discharging end of the chute 1 is clamped at the top of the inner formwork. The bottom of the port of the discharging end of the chute 1 is lapped with the inner edge of the top of the inner formwork. The chute 1 has a certain length. Through the transition of the chute 1, the concrete truck can be kept away from the inner formwork, effectively preventing the truck from scraping the supporting components of the inner formwork and avoiding affecting the alignment and construction quality. During pouring, the concrete output by the truck first flows to the feeding end of the chute 1, then flows to the discharging end through the chute 1, and then enters between the two formworks. Its inclination is relatively small compared with the discharging chute of the truck, so the flowing speed of the concrete decreases. Moreover, the bottom of the port of the discharging end of the chute 1 is lapped with the inner edge of the top of the inner formwork, which can minimize the falling height of the concrete to the greatest extent, effectively prevent the falling concrete from splashing and overflowing to pollute the formwork and the bridge deck, effectively improve the aesthetics, avoid waste of concrete, and at the same time, there is no need for later cleaning, effectively reducing the time invested.

[0036] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the technical solutions of the present invention, rather than limitations on the specific implementation manners of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the claims of the present invention shall be included within the protection scope of the claims of the present invention.
