Description

Technical Field

[0001] This invention relates to the field of construction pouring technology, and more specifically, to a material guiding device for pouring. Background Technology

[0002] In architectural engineering, traditional frame structures are primarily composed of vertical shear walls or frame columns. However, the demands of emerging buildings in recent years have been continuously expanding. Compared to conventional domestic designs, they no longer solely focus on the practicality of the building itself, but also require a combination of practicality and visual appeal. Therefore, emerging buildings are constantly breaking with convention from the design stage, adjusting aspects such as space and form, and some buildings are incorporating spatial structural components.

[0003] Traditional frame structures are basically vertical shear walls or frame columns, which are usually poured together with the upper beams and slabs during concrete pouring. However, for unconventional shear walls or frame columns in spatial structures, it is impossible to pour them together, and conventional pouring methods cannot be used. Therefore, they need to be poured at different designated pouring ports. Because the formwork of spatial frame structures is more complex and the space is more limited, the pouring process is very complicated and cumbersome, time-consuming and labor-intensive, with low pouring efficiency and high construction costs, which affects the pouring effect and quality.

[0004] Therefore, it is necessary to provide a material guiding device for casting to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a material guiding device for casting to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A material guiding device for casting includes a front guide trough, a middle guide trough and a tail guide trough connected in sequence, wherein at least one middle guide trough is provided. The intermediate guide groove is connected to the front guide groove through a connecting mechanism, the tail guide groove is connected to the adjacent intermediate guide groove through the connecting mechanism, and the adjacent intermediate guide grooves are connected to each other through the connecting mechanism. The bottom of the front guide groove, the middle guide groove, and the tail guide groove are all provided with a detachable support mechanism for support and positioning.

[0007] Furthermore, an external groove is provided on the outer wall of one end of both the front guide groove and the middle guide groove, and multiple connection ports are provided on the external groove. An internal groove that matches the external groove is provided on the inner wall of one side of both the middle guide groove and the tail guide groove.

[0008] Furthermore, the connecting mechanism includes: The first elastic element has one end connected to the outer wall of the intermediate guide groove or the tail guide groove, and the other end is provided with a connecting plate. The insertion rod has one end connected to the connecting plate and the other end sliding through into the inner groove. One side of the insertion rod is set as an inclined surface.

[0009] Furthermore, both the outer walls of the intermediate guide groove and the tail guide groove are provided with screws, and a nut sleeve is threadedly connected to the screw. A sleeve post is rotatably connected to the end of the nut sleeve, and two clamping plates are provided on the sleeve post.

[0010] Furthermore, the connecting plate is provided with a slot that matches the card plate, and the distance between the two card plates is greater than or equal to the thickness of the connecting plate.

[0011] Furthermore, the bottom of the front guide groove, the middle guide groove and the tail guide groove are all provided with a hoop, and the bottom of the hoop is provided with a plurality of "L"-shaped connecting plates.

[0012] Furthermore, the support mechanism includes: The U-shaped support is adapted to the hoop, and the bottom of the U-shaped support is provided with two support plates, and a support is rotatably provided between the two support plates; The support is provided with a hollow connecting pipe.

[0013] Furthermore, the support has a through opening, and the support plate has an arc-shaped opening that matches the through opening. The support is fastened to the support plate by fastening bolts.

[0014] Furthermore, the connecting plate has an internal recessed cavity, and a blocking block is slidably connected to the inner wall of the recessed cavity. A second elastic element is provided between the blocking block and the bottom wall of the recessed cavity, and the outward-facing side of the blocking block is set as an inclined surface.

[0015] Furthermore, a pull rod is provided at the bottom of the blocking block, and the other end of the pull rod slides through to the outside of the connecting plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This solution uses a combination design of front guide channel, middle guide channel and tail guide channel to flexibly increase or decrease the number of middle guide channels, adapt to different lengths of pouring paths, solve the problem of adapting to complex pouring paths and variable lengths of spatial components, adapt to the pouring needs of different spatial layouts, solve the problem of traditional pouring methods being difficult to adapt in space-constrained environments, and greatly reduce the difficulty of pouring. Furthermore, the material is guided to the pouring port via the tail guide channel, avoiding the current method of pouring at a designated pouring port location. This cleverly avoids the problem of limited internal space in the formwork frame of a spatial structure. The material can be poured at a convenient location and then fall to the pouring port through the guide device, making pouring simpler and more convenient, saving a lot of time and labor intensity, significantly improving pouring efficiency, effectively reducing construction costs, and improving pouring effect and quality.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-12 A material guiding device for casting includes a front guide trough 1, a middle guide trough 2 and a tail guide trough 3 connected in sequence, wherein at least one middle guide trough 2 is provided. The intermediate guide groove 2 is connected to the front guide groove 1 through the connecting mechanism 4, and the tail guide groove 3 is connected to the adjacent intermediate guide groove 2 through the connecting mechanism 4. The adjacent intermediate guide grooves 2 are connected to each other through the connecting mechanism 4. The bottom of the front guide groove 1, the middle guide groove 2 and the tail guide groove 3 are all provided with a detachable support mechanism 5 for support and limiting.

[0023] In use, after the formwork frame of the spatial structure is erected, based on the length of the pouring path of the spatial structure, a front guide channel 1, at least one intermediate guide channel 2, and a rear guide channel 3 are selected. The front guide channel 1 is then connected to the intermediate guide channel 2, adjacent intermediate guide channels 2, and the intermediate guide channel 2 to the rear guide channel 3 via a connecting mechanism 4, thus forming a complete material guiding channel. The material drop position of the rear guide channel 3 is aligned with the pouring opening of the spatial structure; and each guide channel is inclined towards the pouring opening. Figure 5 As shown, this ensures that the concrete can fall into the pouring opening more effectively.

[0024] A detachable support mechanism 5 is installed at the bottom of the front guide channel 1, the middle guide channel 2, and the rear guide channel 3. Then, each support mechanism 5 is connected to the fastener steel pipe or disc buckle upright of the formwork support frame (or the support mechanism 5 can be installed on the formwork support frame first, and then each guide channel is connected to the support mechanism 5). The support mechanism 5 can support and limit each guide channel, thereby ensuring that the material guide channel maintains a stable posture and realizing the positioning and fixing of the material guide device on the construction site.

[0025] The combined design of the front guide channel 1, the middle guide channel 2, and the tail guide channel 3 allows for flexible adjustment of the number of middle guide channels 2 to accommodate different pouring paths of varying lengths, solving the problem of adapting to complex and variable pouring paths for spatial components. Furthermore, the tail guide channel 3 leads to the pouring port, avoiding the current method of pouring at a designated pouring port location. This cleverly avoids the problem of limited internal space in the formwork frame of spatial structures, allowing pouring to be done at a convenient location and then falling to the pouring port via the guiding device. This makes pouring simpler and more convenient, saving a significant amount of time and labor intensity, significantly improving pouring efficiency, effectively reducing construction costs, and enhancing pouring effect and quality.

[0026] The design of the connecting mechanism enables quick assembly and disassembly and secure connection between the guide channels, preventing loosening of the guide channel connections due to concrete impact during the pouring process and ensuring the stability of the material guiding process.

[0027] In addition, the modular splicing between the front guide channel 1, the middle guide channel 2 and the rear guide channel 3, as well as the detachable support mechanism 5, facilitates transportation, storage and on-site assembly, improving construction efficiency; it also facilitates maintenance and replacement, saving costs and extending the service life of the device when overall maintenance or replacement is required.

[0028] The support mechanism 5 not only provides stable support for each guide channel, ensuring that the material guide channel does not shift or shake during the pouring process, thus guaranteeing the accuracy and stability of concrete pouring; it also enables the rapid installation, fixing, and disassembly of each guide channel, resulting in excellent performance.

[0029] For preferred options, please refer to [link / reference]. Figure 6 , Figure 8 and Figure 10-11 The outer wall of one end of the front guide groove 1 and the middle guide groove 2 is provided with an external groove 6, and the external groove 6 is provided with multiple connection ports 8. The inner wall of one side of the middle guide groove 2 and the tail guide groove 3 is provided with an inner groove 7 that is adapted to the external groove 6.

[0030] Specifically, the splicing direction of the front guide groove 1, the middle guide groove 2, and the tail guide groove 3 is clearly defined, with the outer grooves 6 of the front guide groove 1 and the middle guide groove 2 facing the guide grooves to be spliced; the outer groove 6 of the front guide groove 1 is aligned with the inner groove 7 of the middle guide groove 2 connected to it, and the inner groove 7 of the tail guide groove 3 is aligned with the outer groove 6 of the middle guide groove 2 connected to it, with the heads and tails of adjacent middle guide grooves 2 spliced ​​accordingly. After alignment, push the corresponding guide groove to embed the outer groove 6 into the inner groove 7, and they can be assembled together. At this time, the multiple connection ports 8 on the outer groove 6 correspond to the connection mechanism 4 on the outside of the inner groove 7, thus completing the precise positioning and connection fixation of each guide groove.

[0031] The matching structure of the outer groove 6 and the inner groove 7 enables the rapid and precise docking of each guide groove, avoiding leakage of pouring materials due to misalignment and improving assembly efficiency; the connection port 8 provides a precise installation position for the connection mechanism 4, providing multiple sets of connection points, enhancing the firmness of the guide groove connection, coping with the impact force of concrete during pouring, avoiding misalignment of the guide groove after splicing, and improving connection stability.

[0032] In addition, multiple connection ports 8 can be connected to the corresponding number of connection ports 8 as needed, thereby enabling further adjustment of the extension distance of each guide groove, suitable for fine-tuning of the pouring position, and highly flexible.

[0033] For preferred options, please refer to [link / reference]. Figure 1-6 and Figure 8-11 The connecting mechanism 4 includes: The first elastic element 41 has one end connected to the outer wall of the middle guide groove 2 or the tail guide groove 3, and the other end is provided with a connecting plate 42. The first elastic element 41 in this application can be a spring. The insertion rod 43 has one end connected to the connecting plate 42 and the other end sliding through into the inner groove 7. One side of the insertion rod 43 is set as an inclined surface.

[0034] Specifically, when the guide grooves are connected, the side wall of the outer groove 6 presses against the inclined surface of the insertion rod 43, causing the insertion rod 43 to move outward and drive the connecting plate 42 to stretch the first elastic member 41. When the insertion rod 43 is aligned with the connection port 8 on the outer groove 6, the first elastic element 41 releases its elastic potential energy, pulls the connecting plate 42 to reset, and inserts the insertion rod 43 into the connection port 8, thus achieving the initial fixation of the adjacent guide groove.

[0035] The inclined design of the insertion rod 43, combined with the elastic action of the first elastic element 41, achieves automatic locking of the guide groove docking, eliminating the need for additional tools and simplifying the assembly process. The first elastic element 41 continuously provides tension, ensuring that the insertion rod 43 is stably inserted into the connection port 8, greatly preventing the insertion rod 43 from falling off due to vibration during the pouring process and improving the reliability of the connection. The connecting plate 42 plays a unified linkage role for the insertion rods 43, ensuring that multiple insertion rods 43 move synchronously, guaranteeing the consistency of the connection and facilitating operation.

[0036] During disassembly, pulling the connecting plate 42 will move multiple insert rods 43 together until the insert rods 43 are disengaged from the connecting port 8 of the connected guide groove. The connected guide grooves can then be removed. The operation is simple and convenient.

[0037] For preferred options, please refer to [link / reference]. Figure 1-2 and Figure 8-11 Both the middle guide groove 2 and the tail guide groove 3 are provided with screws 9 on their outer walls. A nut sleeve 10 is threaded onto the screw 9. A sleeve post 11 is rotatably connected to the end of the nut sleeve 10. Two clamping plates 12 are provided on the sleeve post 11.

[0038] Specifically, after the guide groove is initially fixed by the insert rod 43, the nut sleeve 10 is rotated. Since the nut sleeve 10 is threadedly connected to the screw rod 9, the nut sleeve 10 will drive the sleeve post 11 and the clamping plate 12 to move towards the connecting plate 42, so that the sleeve post 11 and the clamping plate 12 are close to the connecting plate 42. Then rotate the sleeve 11 to make it rotate around the nut sleeve 10, thereby adjusting the angle of the two clamping plates 12 (rotating 180 degrees) so that the connecting plate 42 is located between the two clamping plates 12. Continue to rotate the nut sleeve 10 until the clamping plates 12 clamp the connecting plate 42. At this time, the position of the connecting plate 42 and the insert rod 43 is restricted, that is, the insert rod 43 cannot move, completing the secondary locking of the guide groove connection. This can resist the vibration generated by the impact of the pouring material, better withstand the impact load during concrete pouring, prevent the connection from loosening and deforming, and prevent the insert rod 43 from falling off.

[0039] The clamping force of the clamping plate 12 can be controlled by rotating the nut sleeve 10, adapting to the fixing requirements under different working conditions. Furthermore, during subsequent disassembly, rotating the nut sleeve 10 can move the clamping plate 12, causing the clamping plate 12 to move the connecting plate 42 together. The connecting plate 42 then moves the insertion rod 43, ultimately disengaging the insertion rod 43 from the connection port 8. Upon release, the insertion rod 43 will not automatically reset, thus facilitating the disassembly of the guide slots. This can be completed by a single person, saving time and effort and reducing operational difficulty.

[0040] In this embodiment, preferably, please refer to [reference needed]. Figure 1-2 and Figure 8-11 The connecting plate 42 has a slot 13 that matches the card plate 12, and the distance between the two card plates 12 is greater than or equal to the thickness of the connecting plate 42.

[0041] With this design, during secondary locking, after rotating the sleeve 11 and the locking plate 12, the two locking plates 12 are aligned with the slots 13 on the connecting plate 42. Rotating the nut sleeve 10 moves the locking plates 12, causing them to engage in the slots 13. This prevents the locking plates 12 from rotating and falling back to their original position due to vibration or other factors during the pouring process. It ensures the locking effect of the locking plates 12 on the connecting plate 42, ensuring that the connecting plate 42 is fixed without displacement and improving the overall connection stability.

[0042] The nut sleeve 10 can move the clamping plate 12 away from the clamping groove 13, and then make the clamping plate 12 rotate and fall down so that it no longer jams the connecting plate 42, so that it can be disassembled without affecting the disassembly efficiency of the guide groove.

[0043] For preferred options, please refer to [link / reference]. Figure 1-8 and Figure 10 The bottom of the front guide groove 1, the middle guide groove 2 and the tail guide groove 3 are all provided with a hoop 14, and the bottom of the hoop 14 is provided with multiple "L"-shaped connecting plates 15.

[0044] Specifically, the hoop 14 is placed at the bottom of the front guide groove 1, the middle guide groove 2 and the tail guide groove 3, and the bottom of the hoop 14 is provided with a connecting plate 15, all of which can be connected by welding.

[0045] The clamp 14 fits into the bottom of the guide groove, increasing the contact area with the guide groove and improving the load-bearing capacity of the connecting plate 15. The connecting plate 15 can provide a mounting point for the support mechanism 5. The "L"-shaped connecting plate 15 has a simple structure and can be quickly connected with different types of support mechanisms 5, improving construction efficiency.

[0046] Preferably, please refer to the figure. Figure 1-8 , Figure 10 and Figure 12 Supporting mechanism 5 includes: The U-shaped support 51 is adapted to the hoop 14. The bottom of the U-shaped support 51 is provided with two support plates 52, and a support 53 is rotatably provided between the two support plates 52. A hollow connecting pipe 54 is provided on the support 53.

[0047] Specifically, when installing the support mechanism 5, the U-shaped support 51 is inserted into the connecting hanging plate 15, and the U-shaped support 51 is stably attached to the outside of the hoop 14; the hollow connecting pipe 54 on the support 53 is connected to the fastener steel pipe or disc buckle upright of the formwork frame to fix the support mechanism 5, thereby completing the support and limiting of the guide groove.

[0048] According to the pouring angle requirements, the support 53 between the two support plates 52 can be rotated to adjust the tilt angle of the guide channel, so that the guide channel can be adjusted to any tilt angle. This not only better ensures the flow of concrete during pouring, but also adapts to the pouring requirements of spatial components in different directions, making it highly flexible.

[0049] The U-shaped support 51 and the hoop 14 can be quickly engaged without complicated fixing procedures, and the tight fit ensures stable transmission of support force and improves the stability of the guide groove support. The hollow connecting pipe 54 facilitates quick connection with the components of the external formwork frame, and different lengths of components can be selected according to the construction scenario to expand the applicability of the device.

[0050] In this embodiment, preferably, please refer to [reference needed]. Figure 3-4 and Figure 12 The support 53 has a through opening, and the support plate 52 has an arc-shaped opening 16 that matches the through opening. The support 53 is fastened to the support plate 52 by fastening bolts 17.

[0051] With this design, when adjusting the angle of the support 53, the fastening bolt 17 that passes through the support plate 52 and the support 53 is loosened; the support 53 is rotated so that the through port on the support 53 slides along the arc-shaped port 16 of the support plate 52 until the guide groove reaches the preset angle; then the fastening bolt 17 is tightened, and the support 53 and the support plate 52 are fixed by the clamping force of the bolt, thus locking the angle of the guide groove.

[0052] The arc-shaped opening 16 provides guidance and limit for the rotation of the support 53, ensuring precise and controllable angle adjustment and avoiding excessive rotation that could cause the guide channel to deviate. The locking method of the fastening bolt 17 is simple and reliable, and can withstand the weight of the guide channel and concrete, ensuring that the angle of the guide channel remains stable during the pouring process.

[0053] In this embodiment, preferably, please refer to [reference needed]. Figure 4 and Figure 7 The connecting plate 15 has an inner cavity 18, and a blocking block 19 is slidably connected to the inner wall of the inner cavity 18. A second elastic element 20 is provided between the blocking block 19 and the bottom wall of the inner cavity 18. The outward side of the blocking block 19 is set as an inclined surface. The second elastic element 20 in this application can be a spring.

[0054] With this design, when installing the support mechanism 5, the U-shaped support 51 is pushed into the connecting plate 15, and the U-shaped support 51 will press against the inclined surface of the blocking block 19. The blocking block 19 is pressed and slides into the recessed cavity 18, compressing the second elastic element 20. When the U-shaped support 51 is installed in place, the blocking block 19 loses its pressing force, and the second elastic element 20 resets and pushes the blocking block 19 out, thus limiting the U-shaped support 51. This prevents the U-shaped support 51 from moving and falling off, ensures the stable positioning of the blocking block 19, avoids the U-shaped support 51 from loosening and falling off due to pouring vibration, and improves the safety of the support.

[0055] The inclined design of the blocking block 19, together with the second elastic element 20, enables the quick installation of the support mechanism 5. No additional locking parts are required; it can be automatically locked upon insertion, simplifying the installation process and greatly improving the installation efficiency of the support mechanism 5.

[0056] In this embodiment, preferably, please refer to [reference needed]. Figure 4 and Figure 7 A pull rod 21 is provided at the bottom of the blocking block 19, and the other end of the pull rod 21 slides through to the outside of the connecting hanging plate 15.

[0057] With this design, when disassembling the support mechanism 5, the pull rod 21 is pulled down, and the pull rod 21 drives the blocking block 19 to overcome the elastic force of the second elastic element 20 and slide into the recessed cavity 18, thereby releasing the restriction on the U-shaped support 51; after the blocking block 19 is completely removed from the restriction area of ​​the U-shaped support 51, the support mechanism 5 can be directly removed from the connecting hanging plate 15 to complete the disassembly.

[0058] Simply pull lever 21 to unlock; the operation is simple and effortless, improving disassembly efficiency. It also makes it easy to apply force, avoiding the inability to operate due to limited space when unlocking.

[0059] In this embodiment, preferably, the end of the front guide groove 1 is provided with a sealing plate 22, and the interior of the tail guide groove 3 is provided with a closing groove 23.

[0060] With this design, when concrete is poured, the sealing plate 22 can prevent concrete from overflowing from the end of the front guide channel 1, reducing material waste and avoiding pollution of the construction environment. After being guided by the front guide channel 1 and the middle guide channel 2, the concrete enters the tail guide channel 3 and is collected through the closing channel 23 inside the tail guide channel 3, flowing precisely into the designated pouring port. This allows the concrete to be output in a concentrated manner, avoiding concrete diffusion during pouring and improving pouring accuracy.
