Each vertical wall formwork is suspended on the crossbeam via telescopic components. This utility model is applied to the field of concrete casting formwork, allowing all vertical wall formworks to be lifted as a whole and driven to travel as a whole on the box girder bridge deck, eliminating the need for disassembly and transportation of individual formworks, thus significantly saving manual operation and manpower.

Description

Technical Field

[0001] This utility model relates to the field of concrete pouring formwork technology, specifically a formwork vehicle for auxiliary components of box girder bridge decks. Background Technology

[0002] Bridge deck ancillary components are an important part of the box girder bridge deck system. Currently, most box girder bridge deck ancillary components are precast by concrete casting. In the casting process of box girder bridge deck ancillary components, the design of the casting mold structure plays a crucial role in the casting process.

[0003] Currently, most of the casting templates for the auxiliary components of box girder bridge decks on the market are long, single-piece templates. During the casting process, after the auxiliary components solidify in the mold, they need to be demolded. Due to the adhesion between the concrete and the steel mold, demolding is usually done manually and with the help of mechanical structures. This operation is usually quite troublesome and can easily damage the completed auxiliary components. Both mold assembly and demolding involve assembling and dismantling single templates in sequence. There are many single templates, resulting in a huge workload and making it difficult to ensure the straightness of the auxiliary components. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a box girder bridge deck auxiliary component formwork vehicle, which can lift all vertical wall formwork as a whole and drive it to move as a whole on the box girder bridge deck, eliminating the need for disassembling and transporting individual formwork pieces, thereby greatly saving manual operation and manpower.

[0005] To achieve the above objectives, this utility model provides a template vehicle for auxiliary components of a box girder bridge deck, including a traveling truss and casting units disposed on both sides of the traveling truss;

[0006] The casting unit includes a crossbeam and a formwork assembly. One end of the crossbeam is connected to the corresponding side of the traveling truss, and the other end extends outward along the width direction of the box girder bridge deck.

[0007] The number of template components is the same as the number of auxiliary components to be formed. When there are two or more template components, each template component is distributed at intervals along the width direction of the box girder bridge deck.

[0008] The template assembly includes two spaced vertical wall templates, and the two vertical wall templates of the same template assembly form a forming cavity for the corresponding auxiliary component;

[0009] Each of the vertical wall templates is suspended on the horizontal beam via expansion joints.

[0010] In one embodiment, within the same template assembly, the vertical wall template closest to the traveling truss is defined as the inner template, and the vertical wall template furthest from the traveling truss is defined as the outer template.

[0011] The inner template is hinged to the crossbeam or the traveling truss by a retractable first tie rod; and / or

[0012] A second tie rod is hinged between the outer template and the crossbeam.

[0013] In one embodiment, when the number of template components is two or more in the same casting unit:

[0014] In two adjacent template assemblies, two vertical wall templates that are close to each other are rigidly connected to form a double-sided template, and the double-sided template is suspended on the crossbeam by at least one of the telescopic members.

[0015] In one embodiment, connecting angle steel or connecting tie rods are detachably installed on the top of the two vertical wall templates of the same template assembly.

[0016] In one embodiment, a sliding sleeve is slidably connected to the crossbeam, the sliding sleeve having a travel distance that slides along the width direction of the box girder bridge deck;

[0017] Some or all of the telescopic components are suspended on the crossbeam.

[0018] In one embodiment, the box girder bridge deck auxiliary component template vehicle also includes a telescopic drive component, one end of which is hinged to the crossbeam and the other end of which is hinged to the sliding sleeve.

[0019] In one embodiment, the telescopic drive is any one of a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, and an electric telescopic rod.

[0020] In one embodiment, the first end of the crossbeam is connected to the middle position of the corresponding side of the traveling truss, and a reinforcing bar is connected between the second end of the crossbeam and the top of the corresponding side of the traveling truss.

[0021] In one embodiment, the telescopic member is any one of a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, and an electric telescopic rod.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] 1. The box girder bridge deck auxiliary component formwork vehicle of this utility model suspends the vertical wall formwork on the horizontal beam through the telescopic components. The vertical wall formwork can be opened and closed as a whole, so that all the vertical wall formwork can be lifted as a whole. With the help of the traveling truss, the casting unit can be moved as a whole on the box girder bridge deck. There is no need to disassemble and transport individual formwork pieces, which greatly saves manual operation and manpower, improves construction efficiency and reduces labor intensity. Moreover, compared with the existing auxiliary components being prefabricated in the beam storage area or cast in place after the beam is erected, the box girder bridge deck auxiliary component formwork vehicle of this utility model can concentrate the casting of auxiliary components on the platform during the curing time after the box girder is cast, which improves construction convenience and efficiency and reduces the time spent transporting formwork around.

[0024] 2. The box girder bridge deck auxiliary component formwork vehicle of this utility model can perform cyclical operations of walking and pouring on the box girder bridge deck. It is not only easy to operate, but also quick to pour, which can effectively save a lot of manpower and shorten the construction period.

[0025] 3. The box girder bridge deck auxiliary component formwork vehicle of this utility model can connect multiple vertical wall formwork into a whole, and control the closing and demolding of the formwork through telescopic elements such as hydraulic cylinders, screws, air cylinders, electric cylinders or electric push rods. This not only makes the control process more stable and improves the quality of the wall, but also allows the formwork to be opened and closed as a whole without having to be broken down into small pieces, thus improving construction efficiency and effectively saving a lot of manual operation and reducing labor intensity.

[0026] 4. In the preferred embodiment of the box girder bridge deck auxiliary component template vehicle of this utility model, two adjacent vertical wall templates in two adjacent template components are rigidly connected to form a double-sided template. This not only improves the overall structural strength of the box girder bridge deck auxiliary component template vehicle during the forming process, but also enables the hoisting of two vertical wall templates through a telescopic component, thereby reducing costs.

[0027] 5. In the preferred embodiment of the box girder bridge deck auxiliary component template vehicle of this utility model, a sliding sleeve is provided so that the expansion joint and vertical wall template can slide along the width direction of the box girder bridge deck, thereby effectively adapting to the wall changes of the auxiliary components to be formed.

[0039] like Figures 1 to 3 The illustration shows a formwork vehicle for auxiliary components of a box girder bridge deck disclosed in this embodiment. It is mainly used for the cast-in-place casting of auxiliary wall components such as protective walls for high-speed railway box girders. Specifically, the main body of the box girder of the railway bridge deck has been erected, and the casting of auxiliary components is carried out on the road surface of the girder. That is, the formwork vehicle for auxiliary components of the box girder bridge deck in this embodiment can centrally cast auxiliary components on the pedestal during the curing time after the box girder is cast. Compared with existing methods of prefabricating auxiliary components in the girder storage area or casting them in place after the girder is erected, this effectively improves construction convenience and efficiency, and reduces the time spent transporting formwork around the site.

[0040] The box girder bridge deck auxiliary component template vehicle mainly includes a traveling truss 1 and casting units located on both sides of the traveling truss 1. The casting units are mainly used for the in-situ casting of auxiliary components 13 on both sides of the box girder bridge deck 14. The traveling truss 1 is an arched structure with a traveling mechanism 101 at its bottom, such as traveling wheels, to drive the traveling truss 1 to move on the box girder bridge deck 14, thereby transporting the casting units. In other words, the box girder bridge deck auxiliary component template vehicle in this embodiment can perform a cyclical operation of moving and casting on the box girder bridge deck 14. This is not only convenient to operate, but also fast to cast, which can effectively save a lot of manpower and shorten the construction period.

[0041] The casting unit in this embodiment includes a crossbeam 2 and a formwork assembly. The first end of the crossbeam 2 is rigidly connected to the corresponding side of the traveling truss 1 by bolts and / or welding, and the other end extends outward along the width direction of the box girder bridge deck 14, that is, the crossbeam 2 as a whole forms a cantilever structure on the traveling truss 1. Preferably, the first end of the crossbeam 2 is connected to the middle position of the corresponding side of the traveling truss 1, and a reinforcing rod 3 is connected between the second end of the crossbeam 2 and the top of the corresponding side of the traveling truss 1 to improve the overall structural strength of the formwork vehicle for the box girder bridge deck auxiliary components.

[0042] The number of template components is the same as the number of auxiliary components 13 to be formed. When there are two or more template components, the template components are distributed at intervals along the width direction of the box girder bridge deck 14, for example... Figure 1 , Figure 2 The diagram shows casting units with three template components. Each template component includes two spaced-apart vertical wall templates 4, with the two vertical wall templates 4 of the same template component forming a molding cavity 5 for the corresponding auxiliary component 13. In this embodiment, each vertical wall template 4 is suspended on the horizontal beam 2 via a telescopic component 6, thereby connecting all the vertical wall templates 4 into a whole for overall lifting. This allows the template to be opened and closed as a whole without having to be disassembled into smaller pieces, improving construction efficiency and increasing transportation efficiency while reducing manpower consumption.

[0043] In a preferred embodiment, when there are two or more template components in the same casting unit: in two adjacent template components, the two vertical wall templates 4 that are close to each other are rigidly connected to form a double-sided template 401, i.e. Figure 1 , Figure 2 The diagram shows two double-sided templates 401, each suspended from the crossbeam 2 by at least one telescopic member 6. In this embodiment, the double-sided templates 401 are preferably suspended from the crossbeam 2 using only one telescopic member 6. This means that by rigidly connecting two adjacent vertical wall templates 4 from two adjacent template assemblies to form the double-sided templates 401, not only is the overall structural strength of the box girder bridge deck auxiliary component template vehicle improved during the forming process, but the hoisting of the two vertical wall templates 4 can also be achieved using a single telescopic member 6, thus reducing costs.

[0044] In a preferred embodiment, the tops of the two vertical wall templates 4 of the same template assembly are detachably equipped with connecting angle steel or connecting tie rods 7, which further enhances the structural strength of the box girder bridge deck auxiliary component template vehicle during the concrete pouring process.

[0045] In the same template assembly, the vertical wall template 4 closest to the traveling truss 1 is defined as the inner template 402, and the vertical wall template 4 farthest from the traveling truss 1 is defined as the outer template 403. The inner template 402 is hinged to the crossbeam 2 or the traveling truss 1 by a telescopic first tie rod 8; and / or the outer template 403 is hinged to the crossbeam 2 by a second tie rod 9. The first tie rod 8 and the second tie rod 9 can be hydraulic cylinders, screws, pneumatic cylinders, electric cylinders, or electric push rods, etc., for automatically controlling the closing or demolding of the inner template 402 and the outer template 403.

[0046] In this embodiment, a sliding sleeve 10 is slidably connected to the crossbeam 2. The sliding sleeve 10 has a travel distance that slides along the width direction of the box girder bridge deck 14. Some or all of the telescopic components 6 are suspended on the crossbeam 2. For the telescopic component 6 connected to the crossbeam 2, one end is connected to the sliding sleeve 10, and the other end is connected to the corresponding vertical wall template 4. At the same time, a telescopic drive component 11 is hinged between the crossbeam 2 and the sliding sleeve 10 to drive the sliding sleeve 10 to slide, so that the telescopic component 6 and the vertical wall template 4 can slide along the length direction of the crossbeam 2, thereby effectively adapting to the wall changes of the auxiliary components 13 to be formed. Preferably, the telescopic drive component 11 is a driving cylinder. In some embodiments not shown, the telescopic drive component 11 can also be a screw, cylinder, electric cylinder, or electric push rod, or other devices that can realize telescopic movement.

[0047] refer to Figure 1 , Figure 2 The telescopic component 6 corresponding to the outer formwork 403 shown is not suspended on the sliding sleeve 10, while the telescopic components 6 corresponding to the other vertical wall formwork 4 are all suspended on the sliding sleeve 10. In this case, some telescopic components 6 are suspended on the horizontal beam 2. At this time, a downwardly extending connecting column 12 is provided at the second end of the horizontal beam 2. The telescopic component 6 corresponding to the outer formwork 403 and the first tie rod 8 are both hinged to the connecting column 12. Since the outer formwork 403 is on the outermost side, the swinging of its corresponding telescopic component 6 will not cause interference. Therefore, the telescopic component 6 can be directly swung and extended to achieve the lateral displacement of the outer formwork 403. Of course, in specific applications, the telescopic component 6 corresponding to the inner formwork 402 can also be directly suspended on the horizontal beam 2, and the implementation method is the same as... Figure 1 , Figure 2 The connection method of the outer template 403 shown is basically connected, and will not be described in detail in this embodiment. Alternatively, all the vertical wall templates 4, including the outer template 403 and the inner template 402, can be suspended on the sliding sleeve 10, in which case all the expansion joints 6 are suspended on the horizontal beam 2.

[0048] In this embodiment, the telescopic component 6 can be a hydraulic cylinder, or it can be a screw, pneumatic cylinder, electric cylinder, or electric push rod, or other devices that can achieve telescopic movement.

[0049] In this embodiment, the process of the formwork truck for casting auxiliary components 13 on the box girder bridge deck is as follows:

[0050] First, control the displacement of traveling truss 1 to the current preset position;

[0051] Then, the telescopic component 6 is extended so that each vertical wall template 4 hoisted by the telescopic component 6 is lowered to the preset position. At the same time, the outer template 403 and the inner template 402 are rotated inward to the preset position by the first tie rod 8 and the second tie rod 9.

[0052] Then, install the template connecting angle steel or connecting tie rod 7 on each template assembly, connect each vertical wall template 4 into a whole, and pour concrete into each forming cavity 5.

[0053] After the concrete reaches a certain strength, the connecting angle steel or connecting tie rod 7 is removed. The outer formwork 403 and inner formwork 402 are rotated outward to the preset position by the first tie rod 8 and the second tie rod 9, thus completing the demolding of the outer formwork 403 and inner formwork 402.

[0054] Then, control the telescopic component 6 to shorten, lift each vertical wall formwork 4 to separate it from the concrete;

[0055] Finally, control the displacement of traveling truss 1 to another beam that needs to be poured, and start the next cycle.

[0056] The above description is only a preferred embodiment of the present utility model and does not limit the scope of protection of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
