Description

Technical Field

[0001] This utility model relates to the field of structural column casting technology, and in particular to a flow guiding device for concrete casting of structural columns. Background Technology

[0002] Structural columns are constructed on already completed walls and are a key component of partition wall projects, enhancing the overall integrity and stability of the building. Traditional construction methods involve installing reinforcing bars or cages at the desired location for the structural column, then installing formwork on both sides of the wall to fit snugly against the wall surface. A pouring opening is then created at the top of the formwork to pour the concrete into the structural column (e.g.,...). Figure 3 , Figure 4 (As shown).

[0003] The process of pouring concrete for structural columns usually requires pouring concrete from the top of the structural column into the formwork. However, since the top of the structural column is already close to the floor slab, it is difficult to pour the concrete for the structural column, and it may even affect the compactness of the concrete near the top of the structural column, thus affecting the overall quality of the structural column.

[0004] In view of this, existing technologies, in order to facilitate the pouring of concrete into the structural column formwork and reduce the difficulty of concrete pouring, have designed concrete guiding structures for the structural column pouring process. For example, patent application number 201910463099.1 discloses a switchable pouring structure at the pouring port at the upper end of the structural column formwork. This pouring structure allows concrete to enter the structural column formwork under the action of a movable plate and two side plates. Simultaneously, the adjustable movable plate ensures that the concrete at the top of the structural column is densely filled, reducing the difficulty of pouring concrete into the structural column formwork. However, the pouring structure used in this device lacks an arc surface, resulting in poor concrete guiding effect.

[0005] For example, patent number 201621246827.1 discloses a formwork for pouring structural columns based on a standard section combination, including a pouring funnel. This funnel structure guides concrete into the structural column formwork, reducing the difficulty of pouring concrete from the top of the formwork. However, its funnel gate structure is inserted from the top, but the top is often occupied by the floor level (e.g., ...). Figure 3 or Figure 4 As shown in the figure, the funnel gate is difficult to open, which limits the applicability of the device.

[0006] For example, patent number 202111282605.0 discloses an adjustable structural column pouring port template structure, including a template and a structural column pouring port located at the top edge of the template. Fixed plates are fixed on the outer side of the template and on both sides of the structural column pouring port. A movable plate is set between the two fixed plates. The movable plate is hinged to the bottom edge of the structural column pouring port. The movable plate can cover the structural column pouring port by rotating. A support column is slidably connected to the outer side of the movable plate. A support hole is provided on the movable plate. When the movable plate rotates outward, the support column can be inserted into the support hole. Fixed columns are also slidably connected to the movable plate. When the movable plate rotates to cover the structural column pouring port, the fixed columns can extend out of the bottom edge of the movable plate and abut against the outer side of the template to limit the outward rotation of the movable plate, thereby facilitating concrete pouring and reducing the pouring difficulty. However, the pouring structure used in this device does not have an arc surface structure, resulting in poor concrete diversion effect.

[0007] Based on the aforementioned technical deficiencies, and considering the actual construction conditions of structural columns, this research team has initiated a project to study the structure of a flow guiding device for structural column concrete pouring, aiming to reduce the difficulty of concrete pouring, enhance the concrete flow guiding effect, and improve the efficiency of concrete pouring, thereby shortening the construction cycle of structural column concrete pouring and reducing construction costs. This has resulted in a new structure. Utility Model Content

[0008] Based on the above-mentioned technical problems, the present invention provides a flow guiding device for concrete pouring of structural columns. It is designed to match the structure of the structural column template with the mounting plate, ensuring the convenience and stability of installation on the structural column template. In addition, the mounting plate is provided with a flow guiding channel with an arc-shaped structure. At the same time, the top of the channel is inclined from the side of the mounting plate to the side away from the mounting plate. The inclination angle makes the end of the top of the channel away from the mounting plate have a certain distance h from the horizontal plane where the top of the mounting plate is located. This reduces the difficulty of pouring concrete from the top of the structural column template and improves the convenience. Moreover, the arc-shaped flow guiding channel structure helps to improve the flow effect of concrete into the structural column template.

[0009] The specific technical solution is as follows:

[0010] A flow guiding device for concrete pouring of structural columns includes: a structural column template and an installation plate. A pouring port is provided at the end of the structural column template, and an installation hole is provided on the structural column template along the pouring port. The installation plate has an opening that matches the pouring port, and a flow guiding channel is provided on the opening to cover the pouring port; the flow guiding channel is arc-shaped. The installation plate has a positioning hole that matches the installation hole, and the positioning hole and the installation hole are connected as a whole by installation bolts. The top of the flow guiding channel is inclined from the side of the installation plate to the side away from the installation plate, and the inclination angle is such that the distance h between the end of the top of the flow guiding channel away from the installation plate and the horizontal plane of the top of the installation plate is 5-20 cm.

[0011] The design employs a guide channel structure that covers the pouring opening, and the guide channel is arc-shaped. Furthermore, the top of the guide channel slopes from the side of the mounting plate towards the side furthest from the mounting plate. This slope results in a distance h of 5-20cm between the end of the guide channel furthest from the mounting plate and the horizontal plane of the top of the mounting plate. This facilitates the direct placement of the concrete conveying pipe into the guide channel, allowing the concrete to slide into the structural column formwork under the action of the arc surface. This reduces concrete blockage in the guide channel and helps improve construction efficiency. Additionally, the installation structure design, utilizing the mounting plate to install on the structural column formwork, helps ensure overall stability.

[0012] To facilitate simplified installation, ensure installation stability, and prevent the formation of protrusions in the structural column formwork due to the installation bolts, which could lead to grooves on the surface of the cast structural column, preferably, the mounting hole is provided with an internal thread that can match the installation bolt; and / or the positioning hole is provided with an internal thread that can match the installation bolt.

[0013] In order to meet the requirements of concrete sliding down the formwork of the structural column and to match the standard structural column, thereby improving the efficiency of concrete pouring, the radius of curvature of the guide channel is preferably 150-300mm.

[0014] To facilitate the installation of the mounting plate, reduce the difficulty of installation, and achieve pre-positioning of the mounting plate, preferably, the mounting plate has a hanging piece on the side near the top of the structural column template, and the hanging piece can be hung on the structural column template.

[0015] To facilitate the connection of the mounting plate and the structural column template into a whole, and to prevent deformation of the hanging plate during subsequent disassembly, preferably, the hanging plate is provided with a hole that can match the mounting bolt.

[0016] To enhance the stability of the mounting plate on the structural column template, preferably, the bottom end of the mounting plate is integrally formed with an extension plate. The extension plate and the structural column template are provided with rear disassembly holes at corresponding positions. The rear disassembly holes are provided with rear disassembly bolts, and the rear disassembly bolts connect the extension plate and the structural column template into a whole.

[0017] To simplify the process after the structural column is poured, the concrete in the guide channel is cut off in time by inserting a cutting plate, avoiding the drawbacks of difficult, time-consuming, and costly cutting after hardening. Preferably, the mounting plate has a first protrusion and a second protrusion on the side of the structural column template. An insertion groove is formed between the first protrusion and the second protrusion, and a cutting plate is matched in the insertion groove. The cutting plate can be inserted through the insertion groove to cover the pouring opening.

[0018] To facilitate the removal of the mounting plate after pouring and to ensure that the concrete inside the structural column is flattened and sealed for curing, preferably, the structural column template is provided with a second fixing hole along the pouring opening, and the second fixing hole is located at the end of the positioning hole away from the pouring opening; the insert plate is provided with a first fixing hole, the first fixing hole and the second fixing hole are correspondingly set, and the second fixing hole and the first fixing hole can be matched and connected with the mounting bolt.

[0019] To facilitate pushing the cutting plate, preferably, the cutting plate is provided with a pushing handle.

[0020] To prevent displacement when pushing the cutting plate, preferably, the top of the pouring port is provided with a taut wire.

[0021] Compared with the prior art, the technical effects of this invention are reflected in:

[0022] This invention features a simple structure that utilizes the arc-shaped design of the guide channel to improve the sliding effect of concrete into the structural column formwork during pouring, thereby improving the pouring effect and efficiency and reducing construction difficulty.

[0023] This invention involves installing a guide channel on an installation plate and then opening a pouring port on the top of the structural column template. By utilizing the structural design that allows the guide channel to cover the pouring port, the guide channel and the pouring port are matched, reducing the probability of grout leakage during concrete pouring, improving the pouring effect, and reducing the difficulty of pouring. At the same time, the design of the installation plate and the structural column pouring template structure enhances the overall stability.

[0024] The invention also improves the structure of the mounting plate. When the mounting plate is installed on the structural column formwork, it can be positioned by hanging it on the top of the structural column formwork using a hanging plate, and then tightened using mounting bolts. This improves the convenience of installation, reduces the difficulty of installation, and helps to improve construction efficiency.

[0025] This invention further incorporates a first protruding column and a second protruding column on one side of the installation plate located on the structural column template. A cutting groove is formed between the first and second protruding columns, and a cutting plate structure is installed within the cutting groove. Combined with the design of a hanging plate structure and an extension plate structure, this allows the concrete located in the guide groove to be cut off in a timely manner after the concrete in the structural column is poured. This avoids having to wait for the concrete in the structural column to solidify before cutting off the protruding concrete part in the guide groove, which helps to shorten the construction process, reduce construction difficulty, and reduce construction costs.

Detailed Implementation

[0046] To facilitate a correct understanding of the present invention by those skilled in the art, and to enable them to fully understand the technical content of the present invention, the technical solution of the present invention will be further described below in conjunction with specific embodiments. However, this description does not limit the scope of protection claimed by the present invention. Those skilled in the art should not limit the scope of protection of the present invention to the following description. Any equivalent substitutions or changes made by those skilled in the art or those familiar with the art based on the present invention, and based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

[0047] In existing technologies, the construction of structural columns is usually as follows: Figure 3 and Figure 4 As shown, a structural column structure is set on the wall 8. The position for pouring the structural column is reserved during the construction of the wall 8, and the structural column reinforcement 10 (steel cage) is preset at the position for pouring the structural column. After the wall 8 is completed, the structural column formwork 4 is used to close and seal the two sides of the wall 8, and a pouring port 5 (usually a square or rectangular structure) is opened at the top of the structural column formwork 4 on one side for pouring concrete, so as to facilitate the pouring of the structural column concrete. However, the top of the structural column is often affected by the slab 7, which makes the construction of the top concrete pouring more difficult and often results in a large concrete pouring loss rate. Moreover, when the concrete in the structural column is poured to near the top, the open pouring port often makes it difficult to fill the top of the structural column concrete tightly with the upper surface of the slab 7. Even if it can be tightly filled, its local density is poor, resulting in poor overall quality of the structural column. Therefore, during the concrete pouring process of structural columns, the installation of a flow guiding device on the structural column formwork 4 with a pouring opening 5 to allow concrete to be poured from the pouring opening 5 has been extensively studied. However, all of these methods have the following drawbacks: the pouring opening 5 is made into a square or rectangular structure, which makes the flow guiding structure part of the flow guiding device square, making it difficult for the concrete to flow into the center of the structural column and causing it to be dispersed within the structural column formwork, resulting in poor compaction at the center of the structural column; at the same time, due to the unreasonable design of the flow guiding structure, the concrete sliding efficiency is poor, affecting the construction efficiency.

[0048] Based on this, our research team provides: (e.g.) Figure 1-18 As shown, in some embodiments, the concrete pouring guide device for structural columns includes: a structural column formwork 4 and an mounting plate 1, wherein a pouring port 5 is provided at the end of the structural column formwork 4, and mounting holes 6 are provided on the structural column formwork 4 along the pouring port 5 (e.g., ...). Figure 2 (As shown); the mounting plate 1 has an opening that matches the pouring port 5, and a guide groove 2 that can cover the pouring port 5 is provided on the opening, and the guide groove 2 is arc-shaped (as shown). Figure 1(as shown); the mounting plate 1 is provided with positioning holes 3 that can be installed to match the mounting holes 6, and the positioning holes 3 and the mounting holes 6 are connected as a whole by mounting bolts 9 (as shown). Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown), this enhances overall stability; the top of the guide groove 2 is inclined from the side of the mounting plate 1 towards the side away from the mounting plate 1 (as shown). Figure 3-13 As shown), this facilitates the delivery of concrete into the guide channel 2, and the tilt angle ensures that the distance h between the top end of the guide channel 2 away from the mounting plate 1 and the horizontal plane of the top end of the mounting plate 1 is 5-20cm (e.g., Figure 4 As shown), the pipes or other devices for conveying concrete extend into the guide channel.

[0049] During fabrication and use, a pouring opening 5 is made at the top of the structural column formwork 4 on one side, and several installation holes 6 are made along the pouring opening 5 to form a shape like... Figure 2 The structural column template 4 shown is installed and reinforced against the wall 8 at the preset position of the structural column. A template (wooden board, steel plate, etc.) with a width smaller than the structural column template 4 is used as the mounting plate 1. An opening corresponding to and matching the pouring opening 5 is made on the mounting plate 1. Steel plates, aluminum plates, etc., are cut and bent into an arc shape to cover the pouring opening 5, serving as a guide channel 2. Simultaneously, positioning holes 3 matching the mounting holes 6 are provided on the mounting plate 1. The guide channel 2 is then installed on the opening on the mounting plate 1 using bolts or welding, forming a structure as shown. Figure 1 The structure shown is then used; the positioning hole 3 and the mounting hole 6 are connected as a whole using mounting bolts 9, forming a structure as shown. Figure 3 and Figure 4 The structure shown is sufficient.

[0050] like Figure 7 As shown, in some embodiments, the mounting hole 6 is provided with an internal thread, and the internal thread can match the mounting bolt 9; by using the mounting bolt 9 to pass through the positioning hole 3 on the mounting plate 1 and screw it into the mounting hole 6, a stable connection between the structural column template 4 and the mounting plate 1 is achieved, so that the structural column template 4 can form a smooth surface on the side close to the structural column.

[0051] like Figure 7As shown, in some embodiments, the mounting hole 6 is provided with an internal thread, and the internal thread can match the mounting bolt 9; the positioning hole 3 is provided with an internal thread, and the internal thread can match the mounting bolt 9. By screwing the mounting bolt 9 into the positioning hole 3 on the mounting plate 1, and then through the positioning hole 3 and into the mounting hole 6, a stable connection between the structural column template 4 and the mounting plate 1 is achieved, so that the structural column template 4 can form a smooth surface on the side near the structural column.

[0052] In some embodiments, the radius of curvature of the arc surface of the guide groove 2 is 150mm, 170mm, 180mm, 200mm, 210mm, 220mm, 250mm, 280mm, 290mm or 300mm.

[0053] When applying the flow guiding device in the above embodiments to the concrete pouring of structural columns, the research team of this invention also discovered that after the structural column template 4 is fixedly installed on the wall 8 at the preset position of the structural column, during the installation of the mounting plate 1 and the flow guiding channel 2, the mounting bolts 9 often become misaligned when connecting the mounting hole 6 and the positioning hole 3 because the mounting plate 1 is not pre-positioned, resulting in greater installation difficulty and affecting construction efficiency. Therefore, based on the above embodiments, this invention improves the structure of the mounting plate 1 as follows:

[0054] like Figures 8 to 13 As shown, in some embodiments, the mounting plate 1 has a hanging piece 12 on its side near the top of the structural column template 4, and the hanging piece 12 can be hung on the structural column template 4. In use, the mounting plate 1 is hung on the top of the structural column template 4 using the hanging piece 12, so that the opening on the mounting plate 1 is completely fitted with the pouring opening 5, so that the hanging piece 12 positions the mounting plate 1 on the structural column template 4. Then, the mounting bolt 9 is screwed into the mounting hole 6 from the positioning hole 3 to achieve a stable connection between the mounting plate 1 and the structural column template 4, improving the convenience of installation and reducing the difficulty of installation.

[0055] like Figure 10 and Figure 11 As shown, in some embodiments, the mounting plate 12 has a mounting hole 13 that matches the mounting bolt 9. During installation, the mounting bolt 9 is screwed into the mounting hole 6 from the positioning hole 3 and extends through the mounting hole 6 into the mounting hole 13 for connection. In some embodiments, the mounting hole 13 has an internal thread that matches the mounting bolt 9 to enhance the integrity of the connection.

[0056] like Figures 12 to 18As shown, in some embodiments, the bottom end of the mounting plate 1 is integrally formed with an extension plate 19. Rear-removal holes 23 are provided on the extension plate 19 and at corresponding positions on the structural column template 4. Rear-removal bolts 18 are installed within the rear-removal holes 23, and these bolts connect the extension plate 19 and the structural column template 4 into a single unit. This helps to enhance the stability of the connection between the mounting plate 1 and the structural column template 4.

[0057] In some embodiments, the mounting plate 1 has a hanging piece 12 on its side near the top of the structural column template 4, and the hanging piece 12 can be hung on the structural column template 4 (e.g. Figure 8-13 (As shown); the bottom end of the mounting plate 1 is integrally formed with an extension plate 19. Rear disassembly holes 23 are provided on the extension plate 19 and at corresponding positions on the structural column template 4. Rear disassembly bolts 18 are provided within the rear disassembly holes 23, and these bolts connect the extension plate 19 and the structural column template 4 into a single unit (as shown). Figure 12-18 (As shown). This design ensures a stable connection between the mounting plate 1 and the structural column template 4 after the mounting bolts 9 are removed. It facilitates the insertion of a thin sheet between the mounting plate 1 and the structural column template 4, cutting the concrete protruding into the guide groove 2 from left to right or right to left, thus shortening the construction cycle and reducing construction difficulty. The insert sheet can be made of steel plates with thicknesses of 0.5mm, 1mm, 2mm, etc. After cutting, the insert sheet forms a shape like... Figure 15 , Figure 16 The structure shown.

[0058] like Figures 12 to 16 As shown, in some embodiments, the mounting plate 1 has a first protruding post 14 and a second protruding post 15 on one side of the structural column template 4; an insertion groove 16 is formed between the first protruding post 14 and the second protruding post 15, and an insertion plate 17 is matchedly provided in the insertion groove 16, and the insertion plate 17 can be inserted through the insertion groove 16 to cover the pouring port 5. In use, after pouring concrete into the structural column template 4, and until the concrete fills the guide channel 2, the insertion plate 17 (a steel plate with a thickness of 0.5mm, 1mm, 2mm, etc.) is inserted through the insertion groove 16 as follows. Figure 14 As shown, passing through from left to right, forming as Figure 15 The structure shown allows for the cutting away of concrete protruding from the guide channel 2. After the concrete inside the structural column has solidified and cured, the structural column formwork 4 can be directly removed, making the top of the structural column flat on the surface of the wall 8. This avoids the need for cutting after the structural column concrete has solidified, reducing the difficulty of cutting.

[0059] like Figures 14 to 18As shown, in some embodiments, the structural column template 4 has a second fixing hole 22 along the pouring opening 5, and the second fixing hole 22 is located at the end of the positioning hole 3 away from the pouring opening 5; the insert cutting plate 17 has a first fixing hole 21, the first fixing hole 21 and the second fixing hole 22 are correspondingly arranged, and the second fixing hole 22 and the first fixing hole 21 can be matched and connected with the mounting bolt 9. In use, the insert cutting plate 17 is arranged as follows Figure 14 As shown, the right end is inserted into the cutting groove 16, and the first fixing hole 21 on the right end of the cutting plate 17 is aligned with the mounting hole 6 and the positioning hole 3. The mounting bolt 9 is then screwed in and fixed. After the concrete of the structural column is poured, the mounting bolt 9 is unscrewed, and the cutting plate 17 is pushed to the right, so that the cutting plate 17 cuts the concrete and passes through the right end of the cutting groove 16. After the first fixing hole 21 on the right end of the cutting plate 17 is aligned with the second fixing hole 22, the mounting bolt 9 is used to tighten the connection between the first fixing hole 21 and the second fixing hole 22, forming a connection as shown. Figure 15 The structure shown is then modified by removing the rear bolt 18, and the overall structure formed by the mounting plate 1 and the guide channel 2 is removed, resulting in the structure shown. Figure 16 The structure shown allows the mounting plate 1 and the guide channel 2 to be used for the construction and installation of the next structural column after the concrete is poured. It also avoids cutting off the concrete structure that protrudes into the guide channel 2 after the structural column concrete has solidified, reducing the construction difficulty and enabling the structural column to be cast in one go to a certain extent, thus reducing construction costs.

[0060] like Figure 14-16 As shown, in some embodiments, the cutting plate 17 is provided with a push handle 20. This facilitates pushing the cutting plate 17 from left to right or from right to left.

[0061] like Figure 18 As shown, in some embodiments, the top of the pouring port 5 is provided with a taut wire 24. This helps to prevent the cutting plate 17 from being inserted into the concrete inside the structural column during the pushing process, reducing the difficulty of the cutting construction.

[0062] For any other matters not covered in this invention, they can be implemented by referring to existing technology or common knowledge known to those skilled in the art, using conventional technical means, such as: installation of the structural column template 4, installation of the mounting plate 1 on the structural column template 4, bending the guide channel 2 into an arc shape, opening the pouring port 5, ensuring that the guide channel 2 can cover the pouring port 5 is the projection definition that the guide channel 2 can cover on the pouring port 5, the connection between the guide channel 2 and the mounting plate 1, and the construction method of pouring concrete for the structural column.
