Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to an integrated casting formwork device for bridge deck guardrails. Background Technology

[0002] In the bridge deck construction phase of bridge engineering, the construction of the bridge railing base is one of the key processes to ensure the safety and functionality of the bridge. For a long time, the industry has generally adopted a separate construction model, that is, completing the main bridge deck structure first, and then separately pouring the railing base after it has reached a certain strength. While this traditional process can meet basic construction requirements, it has significant drawbacks in terms of construction cycle, labor costs, and material consumption. As the requirements for economy and efficiency in engineering construction continue to increase, its limitations are becoming increasingly apparent.

[0003] In response to industry demands for simplified construction processes and reduced overall costs, integrated construction technology for bridge decks and guardrail bases is gradually being promoted and applied. This technology, by simultaneously casting the guardrail base and bridge deck structure, effectively reduces the time spent on process connections and lowers the labor and material input for secondary construction, offering significant economic and efficiency advantages.

[0004] However, integrated construction faces key technical challenges in practice: the inner formwork of the guardrail base needs to be suspended to ensure structural formation. Current technology commonly uses additional pads inside the formwork for support and fixation from below. This support method has several problems: firstly, the pads remain permanently in the concrete structure after the formwork is removed, damaging the integrity of the concrete and severely impacting the structural aesthetics; secondly, customizing and installing additional support pads increases material costs and requires significant manpower for precise positioning and fixing, thus increasing construction complexity.

[0005] Therefore, it is necessary to study an integrated casting formwork device for bridge deck guardrails. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide an integrated pouring formwork device for bridge deck guardrails, which effectively solves the problems of high construction cost and difficult operation of the inner formwork cantilever in the existing integrated construction formwork structure.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: an integrated pouring formwork device for bridge deck railings, characterized in that: it includes a support, a vertical rod, a cantilever rod, a cantilever seat, an inner formwork, and an outer formwork; a clamp is provided on the inner side of the support, and a groove is provided in the middle of the support; the vertical rod is fixed vertically to the outer side of the support, and the inner formwork is fitted and sealed in the groove; the cantilever rod is fixedly fitted on the upper part of the vertical rod and extends inward to form a cantilever support foundation; a cantilever seat is fixed on the inner formwork, and the cantilever seat is correspondingly fixedly fitted on the cantilever rod; corresponding connecting seats are provided on the outer surfaces of the outer formwork and the inner formwork, and connecting plates are fixedly connected to the connecting seats.

[0008] Furthermore, a limiting seat is fixed to the outer side of the support, and the vertical rod is fixed on the limiting seat. A locking screw is provided on the limiting seat, and the locking seat is fitted on the locking screw and tightened by a nut, so that the outer template is tightly pressed against the outer side of the bridge.

[0009] Furthermore, a flexible pad is provided at the end of the locking seat, and the locking screw is correspondingly provided with the bridge.

[0010] Furthermore, the cantilever rod is a telescopic rod, which includes a sleeve and a socket. The socket has multiple through holes. The sleeve is fitted inside the socket and fixed in the socket by bolts. A threaded connector is provided at the end of the sleeve. The cantilever seat is fitted onto the threaded connector and fixed by a nut.

[0011] Furthermore, a reinforcing rod is also provided on the cantilever rod to form a triangular cantilever system.

[0012] Furthermore, the inner side of the support is provided with a U-shaped groove, a nut is fixed to one side wall of the U-shaped groove, a clamping screw is connected to the internal thread of the nut, an operating handle is provided at the outer end of the clamping screw, and a clamping seat is provided at its inner end.

[0013] The beneficial effects of the above technical solution are as follows: This utility model, focusing on the need for integrated casting of bridge deck and guardrail base, provides a prefabricated formwork device that can be fixed by relying on the side seat of the bridge. It uses the triangular side seat on the side of the bridge as the fixed foundation, and forms a support base point by clamping and fixing with the support. The support is used as the base to support and limit the outer formwork, and then extends vertical rods, cantilever rods and other components to support the inner formwork. The connecting plate between the inner and outer formwork is used to further stabilize and limit the position. The whole adopts a detachable connection structure, which allows the formwork system to be reused. It can not only meet the structural forming requirements of integrated casting, but also simplify the installation and turnover process, reduce the complexity of manual positioning and fixing, reduce the construction difficulty, and shorten the construction cycle.

[0014] Specifically, this invention includes clamps at the ends of the support base, which, combined with the on-site construction environment, clamp the support base to form a stable foundation. Simultaneously, locking seats ensure the stability of the outer formwork support. For the inner formwork, this invention employs a cantilever structure, using a triangular reinforcement system to ensure the suspension support stability of the inner formwork.

[0015] This invention, through the configuration of an adjustment structure, enables the spacing between the inner and outer templates to be adjusted, thereby adapting to different protective base specifications and having a wide range of applications.

[0016] Therefore, this utility model has a novel structure. The overall structure can be assembled and disassembled, which simplifies the assembly and disassembly process, reduces construction difficulty, speeds up formwork turnover, and shortens the construction cycle. At the same time, the sealing and fixing of the outer formwork and the stable support of the inner formwork, combined with the function of the connecting plate, ensure the quality of concrete molding and construction safety.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] Example 1: This example aims to provide an integrated pouring formwork device for bridge deck guardrails, which is mainly used for bridge deck paving. In view of the existing construction methods, when the bridge deck paving and guardrail base are constructed at the same time, the existing formwork system is difficult to carry out effective construction, resulting in problems such as high difficulty in formwork turnover, long construction cycle and high construction difficulty. Based on this, this example provides an integrated pouring formwork device for bridge deck guardrails.

[0027] like Figure 1-2 As shown, an integrated casting formwork device for bridge deck railings includes a support 3, a vertical rod 4, a cantilever rod 6, a cantilever seat 7, an inner formwork 8, and an outer formwork 5; the object targeted in this embodiment is as follows. Figure 1 As shown, a triangular side seat 2 is provided on the side of the bridge 1. The side seat 2 serves as a fixed foundation, and the support 3 is fixed to the side seat 2 by clamping, thereby forming a support foundation. The outer formwork 5 is arranged on the support 3 and sealed against the side of the bridge 1, thereby forming a supporting outer formwork on the outside of the bridge 1. At the same time, in this embodiment, a cantilever structure is arranged with the support 3 as the supporting foundation to support the inner formwork 8.

[0028] In the specific implementation structure, such as Figure 6 As shown, a clamp is provided on the inner side of the support 3. The specific structure of the clamp is that a U-shaped groove is provided on the inner side of the support 3. A nut 20 is fixed on one side wall of the U-shaped groove. A clamping screw 21 is internally threaded to the nut 20. An operating handle 22 is provided on the outer end of the clamping screw 21, and a clamping seat 19 is provided on its inner end. By rotating the operating handle, the clamping seat 19 can be pressed tightly against the side seat 2 to fix the support.

[0029] During implementation, the clamp structure can be integrated with the support 3, or it can be fixed to the side of the support 3 by means of fixed welding or bolt assembly. Through the clamp structure, the support 3 can be detachably fixed to the outer side of the bridge deck.

[0030] A groove 18 is provided in the middle of the support 3. The structure of the groove 18 corresponds to the outer template 5. The outer template 5 is nested in the groove 18 and abuts against the outside of the bridge 1, forming an outer template limit on the outside of the bridge 1. The groove structure can be a recessed groove in the middle area of ​​the groove, or a limit seat 13 is fixed on the outside of the support 3, forming a groove structure between the limit seat 13 and the clamp.

[0031] The vertical rod 4 is fixed vertically to the outside of the support 3. This fixing can be done by integral welding or by threaded connection into the threaded hole on the outside of the support 3. The inner template 8 is fitted with a sealing sleeve in the groove. In specific implementation, the vertical rod 4 is fixed on the limiting seat 13, which is provided with a locking screw 14. The locking seat is fitted onto the locking screw 14 and tightened with a nut, so that the outer template 5 is tightly pressed against the outer side of the bridge 1. A flexible pad is provided at the end of the locking seat 12, and the locking screw 14 is correspondingly provided with the bridge 1.

[0032] This implementation example Figure 4 As shown, the limiting seat 13 forms a fixed foundation for the vertical rod 4. At the same time, the limiting seat 13 extends upward and corresponds to the side of the bridge 1. The limiting seat 13 serves as the foundation, and the locking screw 14 is fixed on it to provide a fixed foundation for the locking seat 12. The locking screw 14 also serves as the locking foundation for the locking seat 12. Through this structure, an outer support and force-applying foundation can be formed on the outside of the outer template 5 to ensure the sealing and stability of the outer template 5 and the side of the bridge 1.

[0033] like Figure 5 As shown, the cantilever rod 6 is fixedly fitted onto the upper part of the vertical rod 4 and extends inward to form a cantilever support foundation; a cantilever seat 7 is fixed on the inner template 8, and the cantilever seat 7 is correspondingly fixedly fitted onto the cantilever rod 6. In the specific cantilever structure, the lower part of the cantilever seat 7 is fixed on the inner template 8, and a connecting hole is provided on its upper part. The cantilever rod 6 is fitted into the connecting hole to support the cantilever seat 7. The specific limiting structure can be provided with corresponding connecting seats 17 on the outer surfaces of the outer template 5 and the inner template 8, and a connecting plate 9 is fixedly connected to the connecting seat 17.

[0034] When using, such as Figure 1 As shown, pavement reinforcement 11 is installed on the bridge deck, and protective seat reinforcement 10 is installed on the bridge 1. The protective seat reinforcement 10 is higher than the pavement reinforcement 11. After the reinforcement is installed, the support 3 is fixed on the side seat at the lower side of the bridge 1, and then the clamping screw is tightened. The vertical rod 4 is fixed on the side of the support 3. Then the outer template 5 is installed in the groove, and the locking seat 12 is fitted on the locking screw 14 and locked with a nut to ensure the sealing between the outer template 5 and the side of the bridge 1. To further ensure the sealing effect, a sealing gasket can be set at the lower part of the outer template 5 and a release agent can be applied to the upper part. After the outer template 5 is installed, the cantilever rod 6 is fixed on the vertical rod 4. Then the cantilever seat 7 on the inner template 8 is fixed to the end of the cantilever rod 6 and tightened with a nut. Finally, the connecting plate is fixed between the inner template 8 and the outer template 5. The spacing of the lower part of the inner template 8 compared with the pavement reinforcement 11 is checked to ensure the thickness of the pavement protective layer.

[0035] Therefore, in this embodiment, the support 3 is fixed to the triangular side seat on the side of the bridge 1 by clamping, forming a stable support foundation. From this base point, vertical rods 4, cantilever rods 6, and other components extend to achieve lateral fixation of the outer formwork 5 and suspended support of the inner formwork 8, respectively. The entire system adopts a detachable connection structure (such as threaded connections, snap-fit, etc.), eliminating the need for lower pads in the formwork system. This not only meets the structural forming requirements of integrated casting but also simplifies the installation and turnover process, reduces the complexity of manual positioning and fixing, lowers construction difficulty, and shortens the construction cycle.

[0036] Example 2 is basically the same as Example 1, except that the structure of the cantilever rod 6 is further explained in this example.

[0037] like Figure 3 As shown in the illustration, in this embodiment, for a given inner and outer mold spacing, a reinforcing rod 15 is further installed on the cantilever rod 6 to form a triangular cantilever system. By installing the reinforcing rod structure, the suspension stability of the inner formwork 8 is ensured; combining the connecting plate and the triangular cantilever system further enhances the connection stability of the cantilever rod 6, preventing the inner formwork 8 from sagging during the pouring process.

[0038] Example 3 is basically the same as Example 1, except that the structure of the cantilever rod 6 is further explained in this example.

[0039] like Figure 7 As shown in the figure, in this embodiment, for the variable inner and outer mold spacing, the cantilever rod 6 is a telescopic rod, which includes a sleeve rod 62 and a sleeve 61. The sleeve 61 is provided with multiple through holes. The sleeve rod 62 is fitted into the sleeve and fixed in the sleeve by bolt assembly. A threaded connector 16 is provided at the end of the sleeve rod. The cantilever seat 7 is fitted into the threaded connector and fixed by nut.

[0040] The telescopic structure allows the length of the cantilever rod 6 to be adjusted, thus adapting to the distance between the inner template 8 and the outer template 5 to a certain extent. To accommodate this structure, corresponding holes are provided on the connecting plate. By setting the corresponding holes on the screws on the connecting seat, the distance between the inner and outer templates 5 can be adjusted adaptively.

[0041] The above-described embodiments of this utility model do not constitute a limitation on the scope of protection of this utility model. The basic concept of this utility model is to provide a prefabricated formwork device that can be fixed by relying on the side abutments of the bridge, in order to meet the requirement of integrated casting of bridge deck and guardrail base. It uses the triangular side abutments on the side of the bridge as the fixed base, and forms a support base point by clamping and fixing with brackets. The brackets support and limit the outer formwork, and then extend vertical bars, cantilever bars and other components to support the inner formwork. The connecting plate between the inner and outer formwork is used to further stabilize and limit the position. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
