Description

Technical Field

[0001] This utility model relates to the field of formwork technology for bridge engineering construction, and in particular to a bottom formwork for a track beam and a track beam formwork system. Background Technology

[0002] Currently, all precast track beams with fulcrum crossbeams adopt the method of post-casting of fulcrum crossbeams. That is, after the track beam is precast as a whole, before the beam body is erected, the fulcrum crossbeams are cast into shape on the construction site using wooden boards.

[0003] The aforementioned construction method of post-casting the fulcrum beams resulted in poor beam appearance quality, requiring extensive post-processing work, which increased the workload of workers and extended the construction period. The construction site also had a high demand for timber, causing unnecessary waste and increasing the economic cost of beam fabrication. Utility Model Content

[0004] In view of this, the present invention provides a bottom formwork and template system for a track beam, which can be used in conjunction with the side formwork and end formwork of the track beam to achieve one-time casting of the support beam and the main beam of the track beam. The beam surface is neat and beautiful, requiring no post-processing, effectively improving the quality of the track beam with support beam, saving construction costs, and improving construction efficiency.

[0005] A bottom mold for a track beam includes a first bottom mold body for supporting the end mold of the track beam; and a second bottom mold body disposed on one side of the first bottom mold body for forming the cavity of the support beam together with the side mold and the end mold of the track beam.

[0006] In one embodiment, the second bottom mold body is used to connect the track beam side mold, and a first adjustment structure is provided between the second bottom mold body and the track beam side mold. The first adjustment structure is used to adjust the installation position of the track beam side mold at the bottom of the second bottom mold body.

[0007] In one embodiment, the first adjustment structure is a waist-shaped hole, which is respectively spaced at corresponding installation positions on the bottom of the second bottom mold body and the side mold of the track beam; the setting direction of the waist-shaped hole on the bottom of the second bottom mold body intersects with the setting direction of the waist-shaped hole on the side mold of the track beam.

[0008] In one embodiment, the first bottom mold body is provided with a second adjustment structure, which is used to adjust the installation position of the bottom of the second bottom mold body on the first bottom mold body; the setting position of the second adjustment structure corresponds to the installation part between the bottom of the second bottom mold body and the side mold of the track beam.

[0009] In one embodiment, the second adjustment structure is a waist-shaped hole, and the setting direction of the waist-shaped hole on the first bottom mold body intersects with the setting direction of the waist-shaped hole at the bottom of the second bottom mold body and the corresponding position of the second adjustment structure.

[0010] In one embodiment, the first bottom mold body is further provided with a third adjustment structure for adjusting the installation position of the track beam end mold on the first bottom mold body according to the beam length; the second bottom mold body is provided with a fourth adjustment structure on the outer periphery for adjusting the installation position of the track beam side mold on the outer periphery of the second bottom mold body according to the beam length.

[0011] In one embodiment, the second bottom mold body includes a first part and a second part, the first part being used to connect the first bottom mold body, and the second part being used to connect the track beam side mold; the connection between the first part and the second part is a ramp structure, and the inclination direction of the ramp structure is consistent with the demolding direction of the second part.

[0012] In one embodiment, the bottom mold of the track beam further includes a third bottom mold body, which is detachably connected to the second part; a telescopic drive assembly is provided between the second part and the third bottom mold body, which is used to drive the second part to detach from the mold.

[0013] In one embodiment, an overlap is provided between the second part and the third bottom mold body, the bottom of the overlap has no support structure, and the telescopic drive component is located below the overlap.

[0014] In one embodiment, the second part has a first hinge seat on its side, the third bottom mold body has a support assembly at its bottom, the support assembly has a second hinge seat at its bottom, and the telescopic drive assembly is hinged at both ends to the first hinge seat and the second hinge seat respectively.

[0015] Based on the same inventive concept as the foregoing embodiments, this application also provides a track beam formwork system, which can be provided with a track beam bottom formwork as described above.

[0016] The track beam bottom formwork and track beam template system provided in this application have at least the following advantages compared with the prior art: The bottom formwork of the track beam is set as the first bottom formwork body and the second bottom formwork body. The second bottom formwork body can form the cavity of the support beam with the track beam side formwork and the track beam end formwork, thereby realizing the one-time casting of the support beam and the main beam of the track beam. The beam surface is neat and beautiful, and no post-processing is required. This effectively improves the quality of the track beam with the support beam, saves construction costs, and improves construction efficiency. To adjust the radius of curvature of the track beam along the bridge direction, the radius of curvature of the track beam side formwork along the bridge direction needs to be adjusted accordingly during construction. This will cause the connection positions between the two ends of the track beam side formwork and the bottom formwork of the track beam to change. By setting a first adjustment structure between the second bottom formwork body and the track beam side formwork, the installation position of the track beam side formwork on the second bottom formwork body can be adjusted to adapt to the change in the connection positions between the two ends of the track beam side formwork and the bottom formwork of the track beam. This ensures that the track beam side formwork can be used for track beams with multiple radii of curvature along the bridge direction, thus greatly improving construction efficiency.

[0023] In the description of this utility model, unless otherwise expressly specified and limited, the terms "first", "second", etc. are used only to distinguish elements with similar properties, and not to indicate or imply relative importance or a specific order.

[0024] The term “include” or any other variation thereof is intended to cover non-exclusive inclusion, which includes not only those elements listed, but also other elements not expressly listed.

[0025] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 9As shown, the bottom mold of the track beam in this embodiment includes a first bottom mold body 10 for supporting the track beam end mold 30; and a second bottom mold body 20, located on one side of the first bottom mold body 10, for forming the cavity of the support beam with the track beam side mold 40 and the track beam end mold 30.

[0026] According to the embodiment of this application, the bottom mold 100 of the track beam is configured as a split structure of a first bottom mold body 10 and a second bottom mold body 20. The second bottom mold body 20 can form a cavity for the support beam with the track beam side mold 40 and the track beam end mold 30, thereby realizing the one-time casting of the support beam and the main beam of the track beam. The beam surface is neat and beautiful, and no post-processing is required. This effectively improves the quality of the track beam with the support beam, saves construction costs, and improves construction efficiency.

[0027] like Figure 3 , Figure 4 , Figures 6 to 8 As shown, specifically in this embodiment, the second bottom mold body 20 is used to connect the track beam side mold 40. A first adjustment structure 21 is provided between the second bottom mold body 20 and the track beam side mold 40. The first adjustment structure 21 is used to adjust the installation position of the track beam side mold 40 at the bottom of the second bottom mold body 20. Specifically, the first adjustment structure 21 is an oblong hole, which is spaced apart at corresponding installation positions on the bottom of the second bottom mold body 20 and the track beam side mold 40. The setting direction of the oblong holes at the bottom of the second bottom mold body 20 intersects with the setting direction of the oblong holes on the track beam side mold 40.

[0028] Specifically, in order to adjust the radius of curvature of the track beam along the bridge direction, the radius of curvature of the track beam side formwork 40 along the bridge direction needs to be adjusted accordingly during construction. This will cause the connection positions between the two ends of the track beam side formwork 40 and the bottom formwork 100 of the track beam to change. By setting a first adjustment structure 21 between the second bottom formwork body 20 and the track beam side formwork 40, the installation position of the track beam side formwork 40 on the second bottom formwork body 20 can be adjusted to adapt to the change in the connection positions between the two ends of the track beam side formwork 40 and the bottom formwork 100 of the track beam. This ensures that the track beam side formwork 40 can be used for track beams with multiple radii of curvature along the bridge direction, thus greatly improving construction efficiency.

[0029] like Figure 3 , Figure 4 , Figures 6 to 8As shown, specifically in this embodiment, the first adjustment structure 21 adopts a waist-shaped hole structure, which is simple and compact, easy to process and adjust, and can greatly avoid cost increases. Specifically, transverse waist-shaped holes and / or longitudinal waist-shaped holes can be provided at intervals at the bottom of the second bottom mold body 20 and the end of the track beam side mold 40, respectively. The transverse or longitudinal waist-shaped holes at the bottom of the second bottom mold body 20 correspond one-to-one with the longitudinal or transverse waist-shaped holes on the track beam side mold 40 to realize the installation of the bottom of the second bottom mold body 20 and the end of the track beam side mold 40. The installation position of the track beam side mold 40 at the bottom of the second bottom mold body 20 can be adjusted through the transverse and longitudinal waist-shaped holes.

[0030] like Figures 5 to 8 As shown, specifically, in this embodiment, the first bottom mold body 10 is provided with a second adjustment structure 12, which is used to adjust the installation position of the bottom of the second bottom mold body 20 on the first bottom mold body 10; the setting position of the second adjustment structure 12 corresponds to the installation part between the bottom of the second bottom mold body 20 and the track beam side mold 40.

[0031] Specifically, in this embodiment, the second adjustment structure 12 is a waist-shaped hole, and the setting direction of the waist-shaped hole on the first bottom mold body 10 intersects with the setting direction of the waist-shaped hole at the bottom of the second bottom mold body 20 and the corresponding position of the second adjustment structure 12.

[0032] Specifically, in this embodiment, the waist-shaped hole on the second bottom mold body 20 that is connected to the second adjustment structure 12 is preferably a waist-shaped hole that is connected to the second bottom mold body 20 and the track beam side mold 40, which can greatly simplify the structure and make assembly and disassembly simple and convenient, thereby effectively improving construction efficiency and saving costs.

[0033] Specifically, in this embodiment, the second adjustment structure 12 adopts a waist-shaped hole structure, which is simple and compact, easy to process and adjust, and can greatly avoid cost increases. Specifically, transverse waist-shaped holes and / or longitudinal waist-shaped holes can be provided at intervals on the bottom of the second bottom mold body 20 and the first bottom mold body 10, respectively. The transverse or longitudinal waist-shaped holes on the second bottom mold body 20 correspond one-to-one with the longitudinal or transverse waist-shaped holes on the first bottom mold body 10 to realize the installation of the first bottom mold body 10 and the second bottom mold body 20. The installation position of the second bottom mold body 20 on the first bottom mold body 10 can be adjusted by using the transverse and longitudinal waist-shaped holes.

[0034] like Figures 5 to 8As shown, specifically, in this embodiment, the first bottom mold body 10 is further provided with a third adjustment structure 13, which is used to adjust the installation position of the track beam end mold 30 on the first bottom mold body 10 according to the beam length; the second bottom mold body 20 is provided with a fourth adjustment structure 23 on its outer periphery, which is used to adjust the installation position of the track beam side mold 40 on the outer periphery of the second bottom mold body 20 according to the beam length. Specifically, in this embodiment, the third adjustment structure 23 and the fourth adjustment structure 23 preferably adopt a waist-shaped hole structure, which is simple and compact, easy to process and adjust, and can greatly avoid cost increases. Specifically, transverse waist-shaped holes and / or longitudinal waist-shaped holes can be provided at intervals on the first bottom mold body 10. The transverse waist-shaped holes or longitudinal waist-shaped holes on the track beam end mold 30 correspond one-to-one with the longitudinal waist-shaped holes or transverse waist-shaped holes on the first bottom mold body 10 to realize the installation of the first bottom mold body 10 and the track beam end mold 30. The installation position of the track beam end mold 30 on the first bottom mold body 10 can be adjusted by the cooperation of the transverse waist-shaped holes and the longitudinal waist-shaped holes. In a straightforward manner, transverse and / or longitudinal waist-shaped holes can be provided at intervals around the outer periphery of the second bottom mold body 20. The transverse or longitudinal waist-shaped holes on the track beam side mold 40 correspond one-to-one with the longitudinal or transverse waist-shaped holes around the outer periphery of the second bottom mold body 20 to achieve the installation of the second bottom mold body 20 and the track beam side mold 40. The installation position of the track beam side mold 40 around the outer periphery of the second bottom mold body 20 can be adjusted by using the transverse and longitudinal waist-shaped holes in combination.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, specifically in this embodiment, the second bottom mold body 20 includes a first part 24 and a second part 25. The first part 24 is used to connect the first bottom mold body 10, and the second part 25 is used to connect the track beam side mold 40. The connection between the first part 24 and the second part 25 is a ramp structure 26, and the inclination direction of the ramp structure 26 is consistent with the demolding direction of the second part 25. Specifically, in this embodiment, by setting the second bottom mold body 20 as a split structure and by designing the ramp structure, the second bottom mold body 20 can be demolded in stages during the demolding process, using an oblique force application method, which greatly reduces the difficulty of demolding and avoids damage to the beam body and impact on the beam quality caused by the overall demolding method.

[0036] like Figures 3 to 6As shown, further, in this embodiment, the bottom formwork of the track beam also includes a third bottom formwork body 50, which is detachably connected to the second part 25; a telescopic drive assembly 60 is provided between the second part 25 and the third bottom formwork body 50, which is used to drive the second part 25 to detach from the formwork. Obviously, by further setting the separate third bottom formwork body 50, the assembly and disassembly of the second part 50 can be realized extremely conveniently, and it is convenient to match the second part 50 of different sizes according to the different curvature radii range of the track beam along the bridge direction to adapt to the stable installation with the side formwork of the track beam, thereby greatly improving the overall adaptability of the track beam formwork system to maximize construction efficiency and reduce construction costs. Specifically, in this embodiment, the telescopic drive assembly 60 can preferably be any one of a hydraulic cylinder, a pneumatic cylinder, an electric steel rod, and a telescopic strut. Specifically, the telescopic drive assembly 60 is respectively hinged to the hinge seat at the bottom of the second part 25 and the hinge seat on the support assembly 51 at the bottom of the third bottom formwork body 50, which has a simple, compact, stable and reliable structure.

[0037] like Figure 5 and Figure 6 As shown, further, in this embodiment, an overlap portion 70 is provided between the second part 25 and the third bottom mold body 50. The bottom of the overlap portion 70 has no supporting structure, and the telescopic drive component 60 is located below the overlap portion 70. By further providing the overlap portion 70 and freeing up space below the overlap portion 70 to arrange the telescopic drive component 60, the telescopic drive process of the telescopic drive component 60 is ensured to be unaffected, thereby greatly ensuring the stability and reliability of the demolding process of the second part 25.

[0038] like Figure 9 As shown, based on the same inventive concept as the foregoing embodiments, this application also provides a track beam formwork system, which can be provided with a track beam bottom formwork 100 as described in the foregoing embodiments, the track beam bottom formwork 100 being connected to the track beam end formwork 30 and the track beam side formwork 40 respectively.

[0039] Obviously, the track beam formwork system of this embodiment, due to the presence of the track beam bottom formwork 100 of the aforementioned embodiment, possesses all the advantages and technical effects of the aforementioned embodiment.

[0040] As can be seen from the above embodiments, the track beam bottom formwork and track beam template system involved in this application can cooperate with the track beam side formwork and track beam end formwork to realize the one-time casting of the track beam support beam and the main beam. The beam surface is neat and beautiful, and no post-processing is required. This effectively improves the quality of the track beam with support beam, saves construction costs, and improves construction efficiency.
