Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically a steel side formwork for concrete pavement. Background Technology

[0002] In concrete pavement construction, side formwork serves the following functions: shaping and fixing, limiting displacement, providing support, controlling elevation, reducing edge damage, and ensuring the neatness of construction joints, thereby ensuring the flatness and stability of the pavement. Steel side formwork structures can prevent the edges of concrete pavement from collapsing, breaking, or deforming during construction and use.

[0003] In existing technologies, side molds are dismantled by striking the mold body with tools. This operation not only damages the side molds but also damages the edges of the concrete pavement, thereby reducing aesthetics, functionality, and practicality. Summary of the Invention

[0004] The problem to be solved by this utility model is to provide a steel side mold for concrete pavement, which overcomes the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a steel side mold for concrete pavement, including an L-shaped plate and an abutment plate. Multiple fixing holes are spaced apart on the horizontal surface of the L-shaped plate for fixing the L-shaped plate to the concrete body. Multiple sliding holes are spaced apart on the vertical surface of the L-shaped plate, and a transmission rod passes through each sliding hole, slidably connected to the sliding hole. The abutment plate is spaced parallel to the vertical surface of the L-shaped plate. One end of the transmission rod is fixed to the surface of the abutment plate, and a spring body is sleeved on the transmission rod. Both ends of the spring body are fixed to the abutment plate and the vertical surface of the L-shaped plate, respectively.

[0006] Optionally, the other end of the transmission rod has a knocking block.

[0007] Optionally, the upper part of the contact plate has a first drain outlet spaced apart, and the lower part of the contact plate has a second drain outlet spaced apart.

[0008] Optionally, connectors are provided near both ends of the L-shaped plate.

[0009] Optionally, the connector includes a fixing block and a fixing sleeve with connecting holes respectively disposed at both ends of the L-shaped plate.

[0010] Optionally, it also includes a first overlapping plate and a second overlapping plate located at both ends of the abutment plate, both of which can be fully fitted with the surfaces of the abutment plate near its two ends.

[0011] Optionally, the bottom of the abutment plate is an inclined surface extending obliquely upward from the side of the abutment plate facing the L-shaped plate to the side facing away from the L-shaped plate.

[0012] The advantages and positive effects of this utility model are as follows: The fixing nails effectively prevent the side mold device from shifting or tipping over during concrete laying, thus improving concrete forming efficiency. The drainage from the first and second drainage outlets effectively prevents excessive water content in the concrete, thus reducing its strength and durability and improving its workability, thereby enhancing its stability and service life. The conical surface abuts the lower parts of both sides of the concrete, increasing the area of ​​the solidified concrete's lower surface and improving its load-bearing capacity. The elastic force of the first, second, and third springs effectively offsets some of the striking force, preventing the abutment plate from bending. The striking action of the first, second, and third striking blocks does not damage the side mold body or the edges of the concrete pavement, thus improving aesthetics, functionality, and practicality.

[0020] As shown in the figure, this utility model provides a steel side mold for concrete pavement, including an L-shaped plate 21 and an abutment plate 29. Two fixing holes 214 are spaced apart on the horizontal surface of the L-shaped plate 21. The fixing holes 214 are fixed to the concrete body 1 by fixing nails 22 passing through the fixing holes 214. Three sliding holes are spaced apart on the vertical surface of the L-shaped plate 21, namely a first sliding hole 211, a second sliding hole 212 and a third sliding hole 213. A first transmission rod 26, a second transmission rod 27 and a third transmission rod 28 are respectively inserted into the three sliding holes. The transmission rods are slidably connected to the sliding holes. The abutment plate 29 is arranged parallel to the vertical surface of the L-shaped plate 21 at intervals. One end of each transmission rod is fixed to the surface of the abutment plate 29. A first spring body 262, a second spring body 272 and a third spring body 282 are respectively sleeved on the three transmission rods. The two ends of each spring body are fixed to the abutment plate 29 and the vertical surface of the L-shaped plate 21.

[0021] To increase the force-bearing area, each transmission rod has a first striking block 261, a second striking block 271, and a third striking block 281 at its other end.

[0022] The upper part of the contact plate 29 has a first drain outlet 293 spaced apart, and the lower part of the contact plate 29 has a second drain outlet 294 spaced apart.

[0023] Connectors are provided on the L-shaped plate 21 near its two ends. The connectors include fixing blocks and fixing sleeves 24 with connecting holes respectively provided at both ends of the L-shaped plate. When the two sets of steel side molds are connected in series, the fixing holes of one set of steel side molds and the fixing sleeves 24 of the other set of steel side molds are connected by a connecting rod.

[0024] It also includes a first overlapping plate 291 and a second overlapping plate 32 located at both ends of the contact plate 29, both of which can be fully attached to the surface of the contact plate 29 near its two ends.

[0025] The bottom of the contact plate 29 is a slope 292 extending obliquely upward from the side of the contact plate 29 facing the L-shaped plate 21 to the side away from the L-shaped plate 21. Similarly, in order to make the overlapping plate fit with the contact plate 29, the part of the first overlapping plate 291 and the second overlapping plate 32 that fits with the slope 292 is also a slope.

[0026] When using the aforementioned steel side formwork for concrete pavements, multiple sets of these steel side formworks need to be combined into two opposing rows. The two rows of steel side formworks are respectively positioned on both sides of the concrete body 1. Each row of steel formwork is composed of multiple steel formworks connected by connectors at both ends of an L-shaped plate. Figure 1As shown, the first side formwork device 2 is fixed to the concrete body 1 by fixing nails 22 and fixing holes 214. The second side formwork device 4 and the third side formwork device 3 are fixed to the concrete 1 in the same way. This avoids the side formwork devices from moving outward or overturning during the laying of concrete, effectively preventing problems caused by movement or overturning, thereby improving the efficiency of concrete forming.

[0027] The connection structure of the two sets of steel side molds refers to the connection structure of the first side mold device 2 and the third side mold device 3 in the figure. The upper part of one side of the L-shaped plate 21 is connected to a first fixing block 23, and the first fixing block 23 has a first connecting hole 231 inside. The upper part of the other side of the L-shaped plate 21 is connected to a fixing sleeve 24, and the inner sides of the fixing sleeve 24 have second connecting holes 241. The second connecting holes 241 are connected to the second fixing block 31 on the second side mold device 3 through a connecting rod 25. The second fixing block 31 on the second side mold device 3 is embedded in the fixing sleeve 24 on the first side mold device 2, and then the connecting rod 25 is inserted into the connecting holes on the second connecting holes 241 and the second fixing block 31. Thus, the connection between the first side mold device 2 and the third side mold device 3 can effectively ensure that the connected side mold devices are in a straight line.

[0028] During demolding, workers use tools to strike the first striking block 261, the second striking block 271, and the third striking block 281 in sequence. This causes the first transmission rod 261, the second transmission rod 272, and the third transmission rod 281 to be stressed. The force of the strikes detaches the contact plate 29 from the solidified concrete. During the strikes, the elasticity of the first spring body 262, the second spring body 272, and the third spring body 282 effectively offsets part of the striking force, preventing the contact plate 29 from bending. Therefore, by disassembling multiple side mold devices in sequence using the above steps, the striking of the first striking block 261, the second striking block 271, and the third striking block 281 will not damage the side mold body or the edges of the concrete pavement, thereby improving aesthetics, functionality, and practicality.

[0029] The first overlapping plate 291 and the second overlapping plate 32 are located in the gap between the two sets of side formwork devices. Their function is to prevent concrete from overflowing from the gap between the sets of side formwork devices before the concrete solidifies. The lower part of the contact plate 29 is provided with a first drainage port 293, which is located on the inclined surface 292. The upper part of the contact plate 29 is provided with a second drainage port 294. During the concrete laying process, the concrete flows to both sides and comes into contact with the contact plates 29 on both sides. If there is too much water in the concrete, it will be drained through the first drainage outlet 293, effectively preventing the strength and durability of the concrete from being reduced due to excessive water content. This improves the strength and durability of the concrete. As the concrete continues to be laid, it flows onto the inclined surface 292. The contact with the inclined surface 292 makes the lower part of the concrete on both sides conical, increasing the area of ​​the lower end of the solidified concrete and improving its load-bearing capacity. During the continued laying of concrete, water may accumulate on the already laid concrete surface. This water can be drained out through the second drainage outlet 294, effectively preventing the workability of the concrete from being affected by excessive water content. This improves the firmness and service life of the concrete.

[0030] The construction process of the steel side formwork used for concrete pavement is as follows: First, install multiple side formwork devices, including the first side formwork device 2, the second side formwork device 4, and the third side formwork device 3. During installation, two fixing nails 22 are inserted into the fixing holes 214 and driven downwards into the ground to fix the first side formwork device 2. Then, the second fixing block 31 on the third side formwork device 3 is embedded into the fixing sleeve 24 on the first side formwork device 2. Next, the connecting rod 25 is inserted into the connecting holes 241 on the second connecting hole and the second fixing block 31 to connect the first side formwork device 2 and the third side formwork device 3. After connection, one side of the second overlapping plate 32 overlaps with one side of the contact plate 29. After fixing multiple side formwork devices, concrete is then laid. During concrete laying, the concrete flows to both sides and abuts against the contact plates 29 on both sides. If there is too much water in the concrete, it will be drained through the first drainage outlet 293. During the continued concrete laying, the concrete flows onto the conical surface 292. The indentation of the inclined surface 292 causes the lower parts of both sides of the concrete to form a cone shape, increasing the surface area of ​​the solidified concrete's lower end. During this continued laying, water may accumulate on the surface of the already laid concrete, which can be drained through the second drain outlet 294. After several days of solidification, the first side formwork device 2 and the third side formwork device 3 can be disassembled. First, remove the two fixing nails 22, then remove the connecting rod 25. At this point, workers use tools to sequentially strike the first striking block 261, the second striking block 271, and the third striking block 281, causing the first transmission rod 261, the second transmission rod 272, and the third transmission rod 281 to be stressed. The striking force causes the contact plate 29 to detach from the solidified concrete. During further striking, the elasticity of the first spring body 262, the second spring body 272, and the third spring body 282 reduces the striking force. Multiple side formwork devices are disassembled in sequence using the above steps.

[0031] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
