[0053] Embodiment one

[0054] As shown in Figures 1 to 9 The present application provides a mounting structure of an anti-collision guardrail outer formwork, which comprises an outer formwork 1 and a guardrail structure reinforcement. The outer formwork 1 is located at the edge of a bridge main body 10, and the inner side of the outer formwork 1 is provided with a connecting piece 14, and the connecting piece 14 is provided with a through hole 141. A stop grout double-sided adhesive tape 5 is arranged between the lower edge of the outer formwork 1 and the bridge main body 10, and the stop grout double-sided adhesive tape 5 seals the gap between the outer formwork 1 and the bridge main body 10. The guardrail structure reinforcement is arranged on the bridge main body 10, and part of the reinforcement of the guardrail structure reinforcement penetrates through the through hole 141, and the outer diameter of the reinforcement is smaller than the inner diameter of the through hole 141.

[0055] The mounting structure of the outer formwork of the crash barrier provided by the embodiments of the present application is located at the edge of the bridge body 10 and does not occupy the position outside the bridge body 10. The outer formwork 1 is fixed by the connecting piece 14 and the guardrail structure steel, without the need to set a connecting structure outside the bridge body 10, and without the need for workers to perform the installation operation of the outer formwork outside the crash barrier. Thus, the problem of limited operation space outside the crash barrier is solved, and the problem of foreign matter falling into the track area during the construction process is avoided. Moreover, the outer formwork 1 is not finally removed, and in the state that the concrete is filled in the pouring cavity 4 and solidified, the outer formwork 1 is connected with the concrete to form an integral whole. Thus, the work of disassembling the outer formwork 1 is reduced, the construction period of the crash barrier is shortened, and the risk of foreign matter entering the free space during the disassembly process is avoided.

[0056] Moreover, the outer formwork 1 and the bridge body 10 are both made of relatively hard materials, and the surface of the bridge body 10 is not smooth. The gap is prone to occur at the contact position of the two. The gap sealing function is achieved by setting the gap sealing double-sided adhesive tape 5 between the outer formwork 1 and the bridge body 10, so as to prevent the grout from flowing out of the gap between the outer formwork 1 and the bridge body 10 during the grouting process.

[0057] The outer diameter of the steel bar is smaller than the inner diameter of the through hole 141. In the state that the concrete is filled in the pouring cavity 4 and solidified, the concrete column is formed between the through hole 141 and the steel bar. The concrete in the hole enables the outer formwork 1 to be “hardly” connected with the concrete of the crash barrier, enhances the integrity of the outer formwork 1 and the concrete structure, and ensures the stable connection of the outer formwork 1 and the concrete.

[0058] In some possible embodiments, the ratio of the outer diameter of the steel bar penetrating through the through hole 141 to the inner diameter of the through hole 141 is greater than 2. Such a ratio can ensure that the concrete grout can smoothly enter the through hole 141 and can minimize the occurrence of air bubbles in the through hole 141. Preferably, the ratio of the outer diameter of the steel bar penetrating through the through hole 141 to the inner diameter of the through hole 141 is greater than 2 and less than 4. According to a large number of experiments, in this range, it can be ensured that the concrete will smoothly enter the through hole 141 to form a concrete column, and the strength of the connecting piece 14 will not be affected.

[0059] In some possible embodiments, the outer formwork 1 includes a steel plate 11, and the connecting piece 14 is a long strip plate body. The connecting piece 14 is vertically connected to the outer formwork 1. A plurality of through holes 141 are arranged on the connecting piece 14, and each through hole 141 is sequentially and spacedly arranged along the length direction of the connecting piece 14. The long strip plate body is vertically connected to the outer formwork 1. The connecting piece 14 extends a distance from the outer formwork 1 toward the inner formwork 22, so as to facilitate the steel bar to penetrate through the through holes 141 on the connecting piece 14. The plurality of through holes 141 arranged on the connecting piece 14 can increase the number of steel bars connected with the connecting piece 14 and improve the connection stability of the outer formwork 1 and the guardrail structure steel.

[0060] The connecting pieces 14 can have various arrangements, and two specific arrangements are described below in the specific implementation process:

[0061] The guardrail structure steel has a plurality of longitudinal steel bars 32, and the guardrail structure steel has a plurality of stirrups 31 sleeved outside the longitudinal steel bars 32.

[0062] Regarding the arrangement of the connecting pieces 14, in some possible embodiments, as shown in FIG. 1, the mounting structure of the outer formwork 1 of the crash barrier includes a plurality of connecting pieces 14, each of which is arranged along the longitudinal direction of the steel plate 11 in sequence and at intervals, each of the connecting pieces 14 extends along the height direction of the steel plate 11, and each of the longitudinal steel bars 32 penetrates through the corresponding through hole 141 of each of the connecting pieces 14. Figure 4

[0063] Specifically, in the longitudinal direction of the steel plate 11, the spacing between the two adjacent connecting pieces 14 is three times the spacing of the stirrups 31 in the guardrail structure steel. Appropriately shortening the spacing between the two adjacent connecting pieces 14 can improve the connection strength, but when the connecting pieces 14 are too dense, the connection strength cannot be greatly improved, and the installation difficulty and construction period are also increased. In order to comprehensively consider the two points, it is concluded through experiments that the spacing between the two adjacent connecting pieces 14 is three times the spacing of the stirrups 31 in the guardrail structure steel, which can balance the improvement of the firmness and the reduction of the installation difficulty.

[0064] The connecting pieces 14 all extend along the height direction of the steel plate 11, and the plurality of connecting pieces 14 are arranged along the longitudinal direction of the steel plate 11 in sequence and at intervals. The longitudinally distributed connecting pieces 14 not only play the role of stiffening ribs of the steel plate 11 formwork to improve the stiffness of the steel plate 11, but also can be used as a longitudinally stressed structure to simplify the arrangement density of the longitudinal steel bars of the crash barrier.

[0065] Regarding the arrangement of the connecting pieces 14, in some possible embodiments, as shown in FIG. 1, the mounting structure of the outer formwork 1 of the crash barrier includes a plurality of connecting pieces 14, each of which is arranged along the longitudinal direction of the steel plate 11 in sequence and at intervals, each of the connecting pieces 14 extends along the height direction of the steel plate 11, and each of the longitudinal steel bars 32 penetrates through the corresponding through hole 141 of each of the connecting pieces 14. Figures 8 to 9

[0066] The connecting pieces 14 all extend along the longitudinal direction of the steel plate 11, and the plurality of connecting pieces 14 are arranged along the height direction of the steel plate 11 in sequence and at intervals. The longitudinally distributed connecting pieces 14 not only play the role of stiffening ribs of the steel plate 11 formwork to improve the stiffness of the steel plate 11, but also can be used as a longitudinally stressed structure to simplify the arrangement density of the longitudinal steel bars of the crash barrier.

[0067] ​​Further, three connecting pieces 14 are arranged on the steel plate 11 in sequence and at intervals along the height direction, and each of the connecting pieces 14 extends along the longitudinal direction of the steel plate 11. Among the three connecting pieces 14, one is close to the upper edge of the steel plate 11, one is close to the lower edge of the steel plate 11, and the other is located at the middle position of the steel plate 11 along the height direction. In this way, the connecting points between the outer formwork 1 and the guardrail structure reinforcement are evenly distributed, and the connection stability of the outer formwork 1 at each position along the height is ensured to be the same.

[0068] Further, the guardrail structure reinforcement has a plurality of stirrups 31, each of which is arranged in sequence along the longitudinal direction of the steel plate 11, the spacing between two adjacent through holes 141 on the connecting piece 14 is equal to the spacing between the stirrups 31 in the guardrail structure reinforcement, and the vertical steel bar segments on each of the stirrups 31 respectively pass through the corresponding through holes 141 on the connecting piece 14. By using the vertical steel bars in the stirrups 31 to pass through the through holes 141 on the connecting piece 14, there is no need to additionally arrange steel bars for connection, and the installation process is more convenient.

[0069] The arrangement modes of the two kinds of connecting pieces 14 described above have respective advantages, and can be adaptively selected according to construction requirements.

[0070] In some possible embodiments, as shown in Figure 1 , Figure 5 The outer formwork 1 further includes an adapter 12, the adapter 12 is connected to the side of the steel plate 11 facing the inner formwork 22, and the adapter 12 and the guardrail structure reinforcement are welded and fixed. By arranging the adapter 12 on the steel plate 11, the steel plate 11 can be connected with the guardrail structure reinforcement in advance before pouring, so as to ensure the position stability of the steel plate 11 before pouring and during pouring. Moreover, the adapter 12 extends from the outer formwork 1 towards the inner formwork 22 by a distance, which can increase the contact area with the guardrail structure reinforcement, and also allows a certain adjustment space for the welding points, so as to reduce the welding difficulty and improve the welding firmness.

[0071] In one possible embodiment, as shown in Figure 4 , the adapter 12 is arranged in three rows in sequence and at intervals along the height direction of the steel plate 11, and is respectively located at the top of the guardrail structure reinforcement, the bottom of the guardrail structure reinforcement, and the middle of the guardrail structure reinforcement. In this way, the connecting points between the outer formwork 1 and the guardrail structure reinforcement are evenly distributed, and the connection stability of the outer formwork 1 at each position is ensured to be the same. Among them, Figure 4 , as shown in d, is a connecting point.

[0072] In some possible implementation, the stirrup 31 and the longitudinal steel bar 32 are fixed by binding. The guardrail structure steel bars have multiple binding positions in the height direction, and each adapter 12 is close to a corresponding binding position. The binding position is fixed by itself, and the connecting piece 14 is connected with the guardrail structure steel bar at the binding position, so that the connection stability is better. In addition, the adapter 12 is connected with the stirrup 31 and the longitudinal steel bar 32 at the binding position, so that the connection firmness is higher.

[0073] The connecting piece 14 and the temporary fixing steel bar are arranged in a staggered manner, and the two stabilize the outer formwork 1 without interfering with each other.

[0074] In some possible implementation, the adapter 12 can be a temporary fixing steel bar welded on the inner side surface of the steel plate 11. The temporary fixing steel bar is welded on the guardrail structure steel bar, and the adapter 12 is arranged as a steel bar, so that the material is easy to obtain, and the cost is low.

[0075] In some possible implementation, the temporary fixing steel bar can be a straight steel bar perpendicular to the steel plate 11. One end of the temporary fixing steel bar is connected with the steel plate 11, and the other end of the temporary fixing steel bar is welded with the guardrail structure steel bar. The temporary fixing steel bar can also be a “U” type. After the temporary fixing steel bar passes through the guardrail structure steel bar, both ends of the temporary fixing steel bar are connected with the steel plate 11. The temporary fixing steel bar can be a strip-shaped steel bar extending along the length direction of the steel plate 11. The steel plate 11 and the guardrail structure steel bar are welded with two sides of the temporary fixing steel bar in the circumferential direction.

[0076] Preferably, the temporary fixing steel bar is welded perpendicularly to the steel plate 11. One end of the temporary fixing steel bar extending away from the steel plate 11 is in contact with the guardrail structure steel bar. The connecting mode is better in the firmness effect than the strip-shaped steel bar extending along the length direction of the steel plate 11, and the material cost is lower and the installation is more convenient than the steel bar being a “U” type.

[0077] In some possible implementation, the steel plate 11 away from the inner formwork 22 is provided with a corrosion-resistant layer. In the state that the concrete is filled in the pouring cavity 4 and solidified, the side of the steel plate 11 away from the inner formwork 22 is not covered in the concrete. In order to prevent the steel plate 11 from being eroded by rainwater and the like, the side of the steel plate 11 away from the inner formwork 22 is provided with a corrosion-resistant layer.

[0078] Example Two

[0079] As Figures 1 to 9As shown, the embodiment of the present application provides a crash barrier construction structure, which comprises the installation structure of the outer formwork of the crash barrier according to the first embodiment and the inner formwork 22. The inner formwork 22 is arranged on the bridge body 10, and a pouring cavity 4 is formed between the inner formwork 22 and the outer formwork 1. In the state that the concrete is filled in the pouring cavity 4 and solidified, the outer formwork 1 is connected with the concrete to form an integral whole, and the concrete is filled in the through hole 141 of the connecting piece 14. The crash barrier construction structure of the embodiment uses the setting structure of the barrier formwork according to the first embodiment. The outer formwork 1 is located at the edge of the bridge body 10, and does not occupy the position outside the bridge body 10. The outer formwork 1 is fixed by the connecting piece 14 and the barrier structure reinforcement, and does not need to be arranged with a connecting structure outside the bridge body 10, and the workers do not need to perform the installation operation of the outer steel formwork outside the crash barrier. Thus, the problem that the operation space outside the crash barrier is limited is solved, and the problem that the foreign matter falls into the track area during the construction process is also avoided. Moreover, the outer formwork 1 is not finally removed. In the state that the concrete is filled in the pouring cavity 4 and solidified, the outer formwork 1 is connected with the concrete to form an integral whole. Thus, the work of removing the outer formwork 1 is reduced, the construction period of the crash barrier is shortened, and the risk that the foreign matter enters the free space during the removal process is avoided.

[0080] In some possible embodiments, the crash barrier formwork setting structure further comprises the matching frame 6 and the tensioning piece 7. The matching frame 6 is arranged on the inner formwork 22, one end of the tensioning piece 7 is limited and matched with the steel plate 11, and the other end of the tensioning piece 7 is limited and matched with the inner formwork 22. The inner formwork 22 is a recycled formwork. When the inner formwork 22 is set, the existing mature setting method is mainly used, and the inner formwork 22 can be stably supported by using a support system. The outer formwork 1 and the inner formwork 22 also need to be connected to ensure that they will not be separated due to grouting and other operations. Therefore, the tensioning piece 7 is arranged between the outer formwork 1 and the inner formwork 22 to ensure the position stability between them.

[0081] In some possible embodiments, the tensioning rod comprises a main rod body 71 and a bent rod 72 located at the end of the main rod body 71. The bent rod 72 is limited on the outer surface of the steel plate 11, the main rod body 71 is arranged through the matching frame 6, and one end of the main rod body 71 that protrudes from the matching frame 6 is connected with a limiting piece. The bent rod 72 is limited by the outer formwork 1 from the outside, so that the outer formwork 1 will not move in the direction away from the inner formwork 22 under the extrusion of the grout. The bent rod 72 is in abutment or welding with the outer formwork 1. The side of the main rod body 71 away from the bent rod 72 is provided with a threaded segment, and the threaded segment is threadedly connected with the limiting piece through the matching frame 6. The matching frame 6 and the limiting piece need to be removed in the later period. The threaded connection is used for installation, and the matching frame 6 and the limiting piece are convenient to disassemble and assemble.

[0082] The above merely describes preferred embodiments of the present application and is not intended to limit the present application in any form. Although the present application has been disclosed with preferred embodiments, it is not intended to limit the present application. Any skilled person in the art can make minor changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and equivalent embodiments with equivalent changes are equivalent. Any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application still belong to the scope of the present application.
