Description

Technical Field

[0001] This utility model relates to the field of prefabrication of double-block railway sleepers, and in particular to a mold system for double-block railway sleepers. Background Technology

[0002] Double-block sleepers are typically used for ballastless track laying and need to be cast in the factory. To improve efficiency, multiple double-block sleepers are formed at one time. Existing technology usually arranges several mold units in a matrix to form a mold system. However, such a mold system requires the production line's transmission device to be designed to be wider and occupy more space. Furthermore, when stacking and curing in the curing pool, it is easy to cause uneven curing, thus affecting the quality of prefabrication. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing double-block sleeper mold system, which makes the production line's transmission device wider and occupies more space, and easily causes uneven curing during stacking and curing. This invention provides a double-block sleeper mold system.

[0004] This utility model provides a mold system for a double-block sleeper, including a frame with a rectangular cross-section, a central partition plate inside the frame, 2-5 mold units on each side of the central partition plate, the mold units on the same side being distributed along the longitudinal direction of the frame, each mold unit including two mold shells, the two mold shells being distributed along the longitudinal direction of the frame, the two sides of the mold shells being connected to the central partition plate and the frame respectively, and the top surface of the frame being provided with several pads. The mold system for a double-block sleeper according to this application has a relatively small impact on the longitudinal length during the prefabrication process because a transfer device is used in each stage of prefabrication. By making the layout of several mold shells longitudinally extended and narrow in width, the width of the transfer device is small, which can effectively save the size and floor space of the transfer device while producing the same number of sleepers at a time. In addition, the narrow mold system width, combined with the pad, makes it easier for each sleeper to fully contact the steam during steam curing, ensuring the steam circulation effect and thus helping to ensure the quality of prefabrication.

[0005] Preferably, the frame includes side plates and end plates, the top surface of the side plates has strip-shaped stiffening plates, and a plurality of pads are spaced apart along the longitudinal direction of the stiffening plates, the stiffening plates and pads being integrally formed components.

[0006] It can effectively ensure the stability and reliability of stacking, and further increase the flow space to ensure full contact with steam.

[0007] Preferably, the top surface of the partition plate is lower than the top surface of the frame, the top surface of the partition plate has a protrusion, and the inner side of the frame and both sides of the protrusion are provided with limiting groove plates, which are used to place the upper chord longitudinal bars in the truss reinforcement.

[0008] This allows for effective steam flow between the two rows of mold shells.

[0009] Preferably, the top end face of the mold shell has a rebar positioning groove, and the outer side of the mold shell is provided with a slot corresponding to the rebar positioning groove. The rebar positioning groove can be detachably connected to the grout-blocking clamp. The grout-blocking clamp includes a first plate, and a second plate is provided on one side of the first plate. The shape and size of the second plate are adapted to the shape and size of the rebar positioning groove, and the shape and size of the first plate are adapted to the shape and size of the slot. The grout-blocking clamp has a slot, and the slot and the rebar positioning groove can form a through hole for the lower chord longitudinal reinforcement in the truss reinforcement to pass through.

[0010] By adopting the above-mentioned setup, and through the improved grout-blocking clamp and slot, it is not only convenient to install and disassemble the grout-blocking clamp, but also to effectively improve the appearance quality of the cast-in-place sleeper.

[0011] The slurry baffle is made of elastic materials such as rubber and polyethylene.

[0012] Preferably, the slurry baffle has a cavity that communicates with the slot opening.

[0013] This helps reduce the strength of the grout-blocking clamp, thus making it easier to snap the grout-blocking clamp into place.

[0014] Preferably, the outer side of the mold shell is provided with an L-shaped plate, and the two corresponding L-shaped plates are used to form the slot. Both sides of the first plate have textures.

[0015] Preferably, the grout-blocking clamp includes a constant-thickness section and a gradually decreasing section. The length of the constant-thickness section is adapted to the depth of the rebar positioning groove. The width of the first plate of the gradually decreasing section gradually decreases, and the thickness of the second plate of the gradually decreasing section gradually decreases.

[0016] Preferably, the end face of the mold shell is further provided with a wing plate, which is located below the rebar positioning groove.

[0017] Preferably, there is a partition between two longitudinally adjacent mold units, a connecting plate between the frame and the partition, and a number of spaced stiffening ribs are provided on the outer side of the frame.

[0018] Preferably, a rotating pressure plate is provided between the two mold shells of the same mold unit.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a mold system for a double-block sleeper. By arranging several mold shells in a longitudinally extended and narrow width, the width of the transmission device is reduced, which can effectively save the size and floor space of the transmission device while producing the same number of sleepers at a time. Furthermore, the narrow mold system width, combined with the pad, allows each sleeper to come into full contact with the steam during stacking and steam curing, ensuring the steam flow effect and thus helping to ensure the prefabrication quality and the prefabrication efficiency of the double-block sleeper.

[0028] Example 1 like Figures 1-6 As shown, a mold system for a double-block sleeper includes a frame 1 with a rectangular cross-section. A central partition 11 is provided inside the frame 1. Two to five mold units are provided on each side of the central partition 11. The mold units on the same side are distributed along the longitudinal direction of the frame 1. Each mold unit includes two mold shells 2, which are distributed along the longitudinal direction of the frame 1. The two sides of the mold shells 2 are respectively connected to the central partition 11 and the frame 1. Several pads 12 are provided on the top surface of the frame 1.

[0029] Specifically, frame 1 contains two rows of mold units, each row containing 2-5 mold units as needed, meaning 4-10 double-block sleepers can be produced at once. Frame 1 includes side plates and end plates, which can be made of channel steel and formed by welding them together in pairs. The top surface of the side plates has strip-shaped stiffening plates 13, and several pads 12 are spaced along the longitudinal direction of the stiffening plates 13. The stiffening plates 13 and pads 12 are integrally formed components. There is a partition 15 between two longitudinally adjacent mold units. There is also a connecting plate between frame 1 and the middle partition 11 to enhance stability. Several spaced stiffening ribs 16 are also provided on the outer side of frame 1. Figures 1-2 As shown.

[0030] The top surface of the partition 11 is lower than the top surface of the frame 1, and the top surface of the partition 11 has a protrusion 111, such as... Figures 1-2 As shown, when the mold system is stacked, there is a larger gap between the middle partition 11 and the upper mold system to increase the flow area. The inner side of the frame 1 and both sides of the protrusion 111 are provided with limiting groove plates 14. The limiting groove plates 14 are used to place the upper chord longitudinal bars in the truss reinforcement, which facilitates the installation and positioning of the truss reinforcement.

[0031] The top of the end face of the mold shell 2 has a rebar positioning groove 21. The end face of the mold shell 2 also has a wing plate 23, which is located below the rebar positioning groove 21. Two L-shaped plates 24 are provided on the outer side of the mold shell 2 corresponding to the rebar positioning groove 21, forming a slot. The grout-blocking clamp 22 includes a first plate body 221. One side of the first plate body 221 has a second plate body 222. The shape and size of the second plate body 222 are adapted to the shape and size of the rebar positioning groove 21. The shape and size of plate 221 are adapted to the shape and size of the slot. The grout-blocking clip 22 has a groove 223. Both sides of the first plate 221 can have textures. The grout-blocking clip 22 can be provided with a cavity connected to the groove 223. The grout-blocking clip 22 includes a constant thickness section and a gradually decreasing section. The height of the constant thickness section and the gradually decreasing section are set according to actual needs. The length of the constant thickness section is adapted to the depth of the rebar positioning groove 21. The width of the first plate 221 of the gradually decreasing section gradually decreases, and the thickness of the second plate 222 of the gradually decreasing section gradually decreases. Figures 3-4As shown, it can effectively ensure the stable installation of the grout-blocking clamp 22 during precast vibration, and prevent the grout-blocking clamp 22 from interfering with the installation of the truss reinforcement. The material of the grout-blocking clamp 22 has a certain elasticity and is provided with an additional cavity, which makes it easier to be squeezed and deformed, and more conducive to being stably clamped in the slot.

[0032] In use, the grout-blocking clamp 22 can extend into the rebar positioning groove 21 through the second plate 222 and the first plate 221 can extend into the slot to form a snap-fit. Its groove 223 and the rebar positioning groove 21 can form a through hole for the lower chord longitudinal reinforcement in the truss to pass through. Figure 5-6 As shown, Figure 5 The groove 223 of the middle retaining grout clamp 22 is the lower chord longitudinal reinforcement, and the two upper longitudinal reinforcements in the truss reinforcement are the upper chord longitudinal reinforcements.

[0033] A rotating pressure plate 17 is provided between the two mold shells 2 of the same mold unit to facilitate the limiting of the upper chord longitudinal ribs and prevent displacement during the casting or transportation process.

[0034] In some alternative embodiments, the slurry baffle 22 can also be configured as a structure with uniform thickness, and the spacing between two adjacent mold units on the same side can be set according to the actual situation.

[0035] In some alternative embodiments, other stiffening structures, such as longitudinally arranged angle steel, may also be provided on the outside of the frame 1.

[0036] In some alternative embodiments, the cavity may be provided only in the section of equal thickness, or only in the portion for extending into the rebar positioning groove 21.

[0037] In some optional embodiments, the number and spacing of the pads 12 are set according to actual needs, and the thickness of the stiffening plate 13 can be the same as the thickness of the pads 12, or it can be set according to actual needs.

[0038] In some alternative embodiments, the protrusion 111 may have a trapezoidal longitudinal cross-section.

[0039] This embodiment of a mold system for a double-block sleeper, by arranging several mold shells in a longitudinally extended and narrow width, results in a smaller width for the transmission device. This effectively saves on the size and floor space of the transmission device while producing the same number of sleepers in a single batch. Furthermore, the narrow mold system width, combined with the pad 12, allows each sleeper to more easily come into full contact with steam during stacking and steam curing, ensuring effective steam flow. This, in turn, helps to guarantee prefabrication quality and ensure the prefabrication efficiency of the double-block sleeper.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
