Description

Technical Field

[0001] This invention belongs to the field of lintel formwork technology, and particularly relates to a precast lintel formwork with through-pipes. Background Technology

[0002] During the construction process, formwork needs to be erected at the top of the window for the construction and pouring of lintels. Most of the existing lintel formwork is made of wood. During construction, the formwork needs to be cut and adjusted and fixed and clamped at multiple points, requiring a lot of on-site handover, resulting in low efficiency.

[0003] Chinese Patent Application Publication No. CN105525750B discloses a construction method for door lintels and an aluminum alloy door lintel template. This aluminum alloy door lintel template is a box-type template composed of a bottom template, side templates symmetrically connected to both sides of the bottom template, and end templates symmetrically connected to both ends of the bottom template. A retractable top rod is provided at the bottom of the box-type template for support. When using the aluminum alloy door lintel template of this invention for door lintel construction, the door lintel and structural beam can be constructed together, allowing them to be formed in one go, ensuring the integrity of the door lintel and structural beam. Furthermore, this invention uses an assembled aluminum alloy door lintel template instead of the existing wooden template, which not only improves the construction quality of the door lintel and increases the number of template turnovers but also saves construction time. However, in actual use, the above template cannot be used for pipe installation during the pouring of the lintel structure and structural beam, and its fit with the side walls is not very adjustable, posing a significant challenge to the precast lintel pouring with pipes. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of the inability to install conduits for wiring during the pouring of lintel structures and structural beams, and the poor adjustability of the formwork to the side walls, and to propose a precast lintel formwork with conduits.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precast lintel template with through-pipes includes two oppositely arranged side wall panels, and a bottom wall panel is coupled between the bottom of the two side wall panels. The bottom wall panel has openings on both sides and a hollow cavity inside. The hollow cavity is equipped with a side distance adjustment mechanism. The side distance adjustment mechanism includes a flexible plate slidably connected in the openings on both sides of the bottom wall panel, which is used to adjust the opening of the openings on both sides to adapt to the thickness of the lintel side wall.

[0007] Both sides of the top of the bottom wall plate are slidably connected to side support plates. A tube adjustment mechanism is embedded in one side of the side support plate, and a tube body is inserted in the tube adjustment mechanism to adjust the longitudinal position of the tube body between the side wall plates.

[0008] As a further description of the above technical solution:

[0009] One side of the side wall panel is connected to multiple connectors by bolts, and the other end of the connectors is connected to the bottom wall panel by another bolt.

[0010] As a further description of the above technical solution:

[0011] Both ends of one side of the side wall panel are provided with through holes, and sealing gaskets are embedded in the through holes. A connecting rib is provided between the two sealing gaskets, and the ends of the connecting ribs are connected to limit nuts by threads. The limit nuts are attached to the outside of the side wall panel to improve the lateral support force of the two side wall panels.

[0012] As a further description of the above technical solution:

[0013] The pipe-through adjustment mechanism includes an adjustment seat, which is embedded in a through hole on one side of the side support plate. A limit clamp is slidably connected to the inner cavity of the adjustment seat, and the limit clamp is sleeved on one side of the end of the pipe body. An adjusting screw is connected to the bottom side of the limit clamp. A screw seat is externally threaded onto the adjusting screw, and the screw seat is connected to one side of the inner cavity of the adjustment seat. A handle is connected to the bottom end of the adjusting screw for adjusting the longitudinal height of the pipe body through the limit clamp.

[0014] As a further description of the above technical solution:

[0015] A flipping block is rotatably connected to one side of the limiting hoop via a pin, and the flipping block extends to the radial inner side of the limiting hoop.

[0016] As a further description of the above technical solution:

[0017] A shielding plate is connected to the bottom side of the limiting hoop, and the two ends of the shielding plate are connected to the corresponding positions of the limiting hoop and the inner cavity of the adjusting seat.

[0018] As a further description of the above technical solution:

[0019] A hinge block is connected to one side of the flexible plate. A connecting rod is rotatably connected to the top of the hinge block. A rotating block is hinged to the other end of the connecting rod. A turntable is located between the two rotating blocks. A shaft is connected to the bottom of the turntable. The shaft is rotatably connected to the bottom side of the bottom wall plate. A rotating gear is connected to the bottom of the shaft. A limiting tooth plate meshes with one side of the rotating gear. The limiting tooth plate is adjustablely connected to the bottom side of the bottom wall plate. A sealing plate, which is also a flexible plate, is connected to one side of the flexible plate.

[0020] As a further description of the above technical solution:

[0021] Both ends of the limiting tooth plate are connected to movable sleeves. A movable rod is slidably connected inside the movable sleeve. The movable rod is connected to the bottom side of the bottom wall plate. A second spring is sleeved on the outer wall of the movable rod. The two ends of the second spring are distributed and connected to the end of the movable rod and the corresponding position on one side of the bottom wall plate, which is used to separate the limiting tooth plate from the rotating gear when moving longitudinally.

[0022] As a further description of the above technical solution:

[0023] A guide rod is connected to the side of the flexible plate away from the hinge block. A movable block is sleeved on the outer wall of the guide rod. The movable block is connected to one side of the inner cavity of the bottom wall plate. A first spring is sleeved on the outer wall of the guide rod. The two ends of the first spring are distributed and connected to the movable block and one side of the flexible plate at corresponding positions.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, when constructing a lintel, the side support plates, side wall plates, and bottom wall plates on both sides of the wall to be lintel can be connected by sliding the corresponding side support plates into the side wall plates. This allows for the connection of the precast template. At this point, pouring from the top of the side wall plates can complete the precasting of the lintel. Furthermore, the pipe body located inside can complete the precasting of the pipe-through lintel. The separable side support plates facilitate quick adjustment of the pipe position during lintel precasting, improving pipe processing efficiency. This also facilitates the precasting of pipelines during lintel pouring by setting up the pipe body, thereby improving processing efficiency.

[0026] 2. In this invention, the designed pipe-through adjustment mechanism allows the adjusting screw to rotate within the screw seat. The rotation of the adjusting screw drives the movement of the limiting hoop, which in turn moves the inner-limited pipe body, adjusting the relative depth of the pipe body within the side wall panel. This improves the adaptability of the pipe-through prefabrication. Furthermore, the designed flipping block can rotate to abut and seal the pipe body. After the lintel formwork is poured, the flipping block is turned to separate from the pipe body. The pipe body can also be separated from the lintel formwork by tapping, facilitating the reuse of the pipe body.

[0027] 3. In this invention, the edge distance adjustment mechanism is designed so that the limiting tooth plate is pulled to move the movable sleeve outside the moving rod. After the limiting tooth plate separates from the rotating gear, the rotating gear can rotate to drive the turntable and the rotating blocks on both sides to move. The movement of the rotating blocks can drive the connecting rod to move. The movement of the connecting rod can pull the hinge block and the flexible plate at the other end to move. When the flexible plate moves, it can adjust and unfold the opening on the bottom side of the bottom wall plate. This is beneficial to achieve the unfolding position of the opening on the bottom side of the bottom wall plate through the flexible plate that can be unfolded to each other. It is convenient to achieve full fit of the walls on both sides of the lintel by adjusting the position of the bottom opening, which is beneficial to improve the support adaptability of the lintel template with different widths.

[0037] 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.

[0038] Please see Figure 1-7 The present invention provides a technical solution: a precast lintel template with through-pipe, comprising two oppositely arranged side wall panels 1, and a bottom wall panel 2 coupled between the bottom of the two side wall panels 1. The bottom wall panel 2 has openings on both sides and a hollow cavity is provided inside the bottom wall panel 2. The hollow cavity is provided with a side distance adjustment mechanism 7. The side distance adjustment mechanism 7 includes a flexible plate 701 slidably connected in the openings on both sides of the bottom wall panel 2, for adjusting the opening degree of the openings on both sides to adapt to the thickness of the lintel side wall.

[0039] Both sides of the top of the bottom wall plate 2 are slidably connected to side support plates 8. A tube adjustment mechanism 5 is embedded in one side of the side support plate 8, and a tube body 6 is inserted in the tube adjustment mechanism 5 to adjust the longitudinal position of the tube body 6 between the side wall plates 1. A plurality of connectors 3 are limited to one side of the side wall plate 1 by bolts, and the other end of the connector 3 is limited to one side of the bottom wall plate 2 by another bolt. Both ends of one side of the side wall plate 1 are provided with through holes, and sealing gaskets are embedded in the through holes. A connecting rib 4 is provided between the sealing gaskets on both sides, and the ends of the connecting rib 4 are connected to limit nuts by threads. The limit nuts are attached to the outside of the side wall plate 1 to improve the lateral support force of the two side wall plates 1.

[0040] The specific implementation method is as follows: Through the designed lintel template, when the lintel is constructed, the side support plate 8, side wall plate 1, and bottom wall plate 2 can be installed between the two side walls of the lintel to be constructed. In this embodiment, the side support plate 8, side wall plate 1, and bottom wall plate 2 are connected to the wall by the bottom opening of the bottom wall plate 2 being fitted onto the top of the two side walls, and the L-shaped plate is connected to the wall through the bottom reserved hole. After the bottom wall plate 2 is connected, the corresponding side support plate 8 can be slid into the side wall plate 1 to complete the connection of the prefabricated template. At this time, the lintel can be prefabricated by pouring from the top of the side wall plate 1, and the pipe body 6 located inside can complete the prefabrication of the pipe lintel. Thus, the separable side support plate 8 can facilitate the quick adjustment of the pipe position during the prefabrication of the lintel, which can improve the efficiency of pipe processing. It is beneficial to facilitate the prefabrication of pipelines during the pouring of the lintel by setting the pipe body, thereby improving the processing efficiency.

[0041] Furthermore, the designed connecting rib 4 can ensure a tight connection with the side wall panel 1 through the limit nuts on both sides, and the compressive strength of the side wall panel 1 can be easily and quickly adjusted by rotating the limit nuts. In addition, the sealing gasket through the connecting rib 4 can close the opening on one side of the side wall panel 1, which is beneficial to improving the stability of the building.

[0042] Please see Figure 5-6 The pipe-through adjustment mechanism 5 includes an adjustment seat 501, which is embedded in a through hole on one side of the side support plate 8. A limiting clamp 502 is slidably connected to the inner cavity of the adjustment seat 501, and the limiting clamp 502 is sleeved on one side of the end of the pipe body 6. An adjusting screw 504 is connected to the bottom side of the limiting clamp 502. A screw seat 505 is externally threaded to the adjusting screw 504 and connected to the screw seat 505 on one side of the inner cavity of the adjustment seat 501. A handle is connected to the bottom end of the adjusting screw 504 for adjusting the longitudinal height of the pipe body 6 through the limiting clamp 502. A flipping block 503 is rotatably connected to one side of the limiting clamp 502 via a pin. The flipping block 503 extends to the radially inner side of the limiting clamp 502. A shielding plate 506 is connected to the bottom side of the limiting clamp 502, and the two ends of the shielding plate 506 are distributed and connected to the corresponding positions of the limiting clamp 502 and the inner cavity of the adjustment seat 501.

[0043] The specific implementation method is as follows: Through the designed pipe-through adjustment mechanism 5, when setting up the pipe, the adjusting screw 504 can be rotated in the screw seat 505. The rotation of the adjusting screw 504 can drive the limiting hoop 502 to move. The movement of the limiting hoop 502 can drive the inner limiting pipe body 6 to move, thereby adjusting the relative depth of the pipe body 6 in the side wall plate 1, which is beneficial to improving the adaptability of pipe prefabrication. In addition, through the designed flipping block 503, the flipping block 503 can abut and close the pipe body 6 by rotating. After the lintel formwork is poured, the flipping block 503 can be turned to separate from the pipe body 6. At this time, the pipe body 6 can be separated from the lintel formwork by knocking, which is convenient for the reuse of the pipe body 6.

[0044] In another embodiment, the pipe body 6 can also be a flexible or rigid plastic pipe with the strength to support the casting, which can be directly embedded into the lintel template after prefabrication, and only the side support plates 8 on both sides need to be slid out and separated.

[0045] Furthermore, the designed shielding plate 506 can easily seal the inner opening of the adjusting seat 501, preventing the pouring slurry from leaking outward.

[0046] Please see Figure 3-4 and Figure 7The flexible plate 701 is connected to a hinge block 703 on one side. A connecting rod 704 is rotatably connected to the top of the hinge block 703. A rotating block 708 is hinged to the other end of the connecting rod 704. A turntable 709 is located between the two rotating blocks 708. A shaft is connected to the bottom of the turntable 709 and is rotatably connected to the bottom side of the bottom wall plate 2. A rotating gear 710 is connected to the bottom of the shaft, and a limiting tooth plate 711 meshes with one side of the rotating gear 710. The limiting tooth plate 711 is adjustablely connected to the bottom side of the bottom wall plate 2. A closing plate 702 is connected to one side of the flexible plate 701. The closing plate 702 is the flexible plate 701. Movable sleeves 712 are connected to both ends of one side of the limiting tooth plate 711. The movable sleeves 712 slide within the moving sleeves 712. A movable rod 714 is connected to the bottom side of the bottom wall plate 2. A second spring 713 is sleeved on the outer wall of the movable rod 714. The two ends of the second spring 713 are distributed and connected to the end of the movable rod 714 and one side of the bottom wall plate 2 at corresponding positions. The limiting tooth plate 711 for longitudinal movement is separated from the rotating gear 710. A guide rod 707 is connected to the side of the flexible plate 701 away from the hinge block 703. A movable block 706 is sleeved on the outer wall of the guide rod 707. The movable block 706 is connected to one side of the inner cavity of the bottom wall plate 2. A first spring 705 is sleeved on the outer wall of the guide rod 707. The two ends of the first spring 705 are distributed and connected to the movable block 706 and one side of the flexible plate 701 at corresponding positions.

[0047] The specific implementation method is as follows: Through the designed edge distance adjustment mechanism 7, the moving sleeve 712 can be moved outside the moving rod 714 by pulling the limiting tooth plate 711. After the limiting tooth plate 711 is separated from the rotating gear 710, the rotating gear 710 can rotate to drive the turntable 709 and the rotating blocks 708 on both sides to move. The movement of the rotating blocks 708 can drive the connecting rod 704 to move. The movement of the connecting rod 704 can pull the hinge block 703 and the flexible plate 701 at the other end to move. When the flexible plate 701 moves, the opening on the bottom side of the bottom wall plate 2 can be opened by adjusting the movement. This is beneficial to realize the opening position of the bottom side opening of the bottom wall plate 2 through the flexible plate 701 that can be opened to each other. It is convenient to achieve full fit of the walls on both sides of the beam by adjusting the position of the bottom opening, thereby improving the support adaptability of the beam template of different widths.

[0048] Furthermore, through the designed sealing plate 702, the sealing plate 702 can block and prevent leakage of the top-poured grout, thereby improving the treatment compatibility;

[0049] Furthermore, through the design of the guide rod 707, the movement of the guide rod 707 within the moving block 706 is more efficient, thereby preventing the flexible plate 701 from swaying or shifting and ensuring stability.

[0050] Working principle: During use, when constructing the lintel, the side support plate 8, side wall plate 1, and bottom wall plate 2 are installed between the two walls of the lintel to be constructed. The prefabricated template is connected by sliding the corresponding side support plate 8 into the side wall plate 1. At this time, the lintel can be prefabricated by pouring from the top of the side wall plate 1. The pipe body 6 located inside completes the prefabrication of the pipe lintel. The pipe position can be quickly adjusted during the prefabrication of the lintel by the separable side support plate 8. The connection of the reinforcing bar with the side wall plate 1 is ensured by the connection of the limit nuts on both sides. The compressive strength of the side wall plate 1 can be easily and quickly adjusted by rotating the limit nuts.

[0051] During the installation of the pipe, the adjusting screw 504 is rotated within the screw seat 505. The rotation of the adjusting screw 504 causes the limiting clamp 502 to move. The movement of the limiting clamp 502 causes the inner limiting pipe body 6 to move, adjusting the relative depth of the pipe body 6 within the side wall panel 1, thereby improving the adaptability of the pipe prefabrication. The rotating block 503 abuts and seals the pipe body 6 by rotating. After the lintel formwork is poured, the rotating block 503 is rotated to separate from the pipe body 6. The pipe body 6 is also separated from the lintel formwork by tapping.

[0052] By pulling the limiting toothed plate 711, the moving sleeve 712 moves outside the moving rod 714. After the limiting toothed plate 711 separates from the rotating gear 710, the rotating gear 710 rotates, causing the turntable 709 and the rotating blocks 708 on both sides to move. The movement of the rotating blocks 708 causes the connecting rod 704 to move. The movement of the connecting rod 704 pulls the hinge block 703 and the flexible plate 701, which are hinged at the other end, to move. When the flexible plate 701 moves, it adjusts and unfolds the opening on the bottom side of the bottom wall plate 2. This facilitates the unfolding position of the opening on the bottom side of the bottom wall plate 2 through the flexible plate 701, which can unfold with each other. It also facilitates the full fit of the walls on both sides of the lintel by adjusting the position of the bottom opening, thereby improving the support adaptability of the lintel template with different widths.
