Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a building template. Background Art

[0002] Building formwork is a temporary mold support system used in the construction of cast-in-place concrete structures. It is usually made of materials such as wood, metal or plastic. Its core function is to provide shaped support for unsolidified concrete, ensuring that the components form the geometric shape, size and surface flatness required by the design. Through the precise erection of the formwork system, it can not only control the quality of the project and accelerate the construction progress, but also ensure operational safety. Its reusable nature significantly reduces construction costs.

[0003] The existing plastic-steel formwork system is assembled from multiple panels. During assembly, the panels are locked together by inserting a latch rod into a hole on the side of each panel and then inserting a wedge-shaped clamp into a slot on the latch rod. To ensure the secure connection between the two panels, a worker must strike the wedge clamp with a hammer after inserting the wedge clamp into the slot on the latch rod to tighten the two panels.

[0004] There are multiple connection points between the templates, which require multiple hammering operations, resulting in a long construction time, low construction efficiency, and high labor intensity;

[0005] In addition, the method of tightening the wedge-shaped clamps by hammering causes the template to be subjected to vibration and impact, which damages the overall structure of the assembly. In addition, there is a situation where the hammering is offset on the plate body, causing damage to the plate body and shortening its service life.

[0006] In addition, since the wedge-shaped clamp is tightly squeezed against the inner wall of the slot on the latch rod after being hammered, it is not only difficult to disassemble later, but also structural damage such as deformation of the latch rod and wedge-shaped clamp or expansion of the slot may easily occur after long-term and repeated use, increasing replacement costs. Summary of the Invention

[0007] The purpose of the present invention is to provide a building template to solve the technical problems raised in the above background technology.

[0011] Preferably, the formwork panel is formed as an integral body of a plate body and a frame body, the frame body is located on the side of the plate body away from the concrete, and the clamping holes are distributed on the four sides of the frame body. When the circular clamping seat is fully inserted into the clamping hole, the end face of the circular clamping seat is located inside the clamping hole, so that the clamping arm is in conflict with the clamping hole port, and each clamping arm is provided with a clamping port.

[0012] Preferably, the pushing mechanism includes a cylindrical rod and a pushing module. The pushing module is arranged on the plate body. The plate body is located on the four sides of the pushing module and mounting seats are fixed corresponding to each clamping hole. Each mounting seat is provided with a through sliding hole. A cylindrical rod is slidably installed in each sliding hole. One end of the cylindrical rod is hollow and the other end is sealed, and the hollow end faces the clamping hole. The inner diameter of the hollow part of the cylindrical rod matches the outer diameter of the guide rod. The pushing module is used to simultaneously push the four cylindrical rods to move toward the side where the clamping hole is located.

[0013] Preferably, the pushing module includes a threaded rod and a conical pushing head, a cylindrical seat is fixed on the plate body, and side notches are provided on the outer peripheral wall of the cylindrical seat corresponding to the positions of each mounting seat, a threaded hole is provided on the end face of the cylindrical seat, and the threaded rod is screwed into the threaded hole with matching threads, and the conical pushing head is installed on the end of the threaded rod extending into the cylindrical seat, and the small diameter end is adjacent to the plate body, and one end of each cylindrical rod away from the clamping hole extends into the cylindrical seat through the side notch, and is respectively fixed with a wedge-shaped extrusion block, and each wedge-shaped extrusion block is extruded and matched with the conical pushing head, and a first hand wheel is installed on the other end of the threaded rod.

[0014] Preferably, an annular disk is fixedly mounted on each cylindrical rod between the mounting seat and the wedge-shaped extrusion block, and a second spring is mounted on each cylindrical rod, one end of the second spring is fixed to the annular disk, and the other end is fixed to the mounting seat.

[0015] Preferably, four auxiliary reinforcing ribs are evenly distributed on the outer peripheral wall of the cylindrical seat, and the ends of each auxiliary reinforcing rib are fixed to the four corners of the frame body in a one-to-one correspondence, and each auxiliary reinforcing rib is fixed to the plate body.

[0016] Preferably, the connecting member includes a shaft and two connecting plates, the two connecting plates are arranged symmetrically, the shaft is provided on one side of the two connecting plates, and connecting arms are fixed to the side ends of the two connecting plates respectively, and each connecting arm is rotatably mounted on the shaft, and the circular bracket is correspondingly fixed on the surface of the connecting plate. An adjustment mechanism is commonly provided on the two connecting plates, and the adjustment mechanism is used to drive the two connecting plates to rotate and adjust around the shaft at the same time to achieve angle adjustment.

[0017] Preferably, the adjustment mechanism includes an internal threaded sleeve and a bidirectional screw. Both connecting plates are provided with mounting grooves. Both mounting grooves are provided with internal threaded sleeves which are rotatably installed via a rotating shaft. The rotating shaft is arranged parallel to the shaft rod.

[0018] Preferably, the connecting plate is provided with plug rods fixed on both sides of the circular card seat, and the four sides of the frame are provided with plug holes for the plug rods to be inserted on both sides of each card hole.

[0019] Compared with the prior art, the present invention has the following beneficial effects.

[0020] When the ring sleeve is pushed to move by the pushing mechanism, the connection between the traction arm and the clamping arm protrudes outward in an expanded diameter, and cooperates with the clamping hole port to form a mechanical lock. When operating the pushing mechanism, there is no need to use special tools, instead of using the traditional wedge-shaped clamp for locking. The greater the pushing mechanism pushes the ring sleeve to move toward the side of the circular clamping seat, the higher the tension.

[0021] The pushing mechanism pushes the four cylindrical rods to move synchronously toward the side of the clamping hole to push the ring sleeve through the pushing module, realizing multi-point synchronous locking. During disassembly, the pushing of the ring sleeve can be cancelled at the same time, making disassembly and assembly convenient and quick, and reducing the labor intensity of the staff.

[0022] The two connecting plates of the connecting part can rotate around the shaft, and cooperate with the bidirectional screw thread in the adjustment mechanism to drive the two internal threaded sleeves to move to adjust the angle between the two connecting plates, forming a modular and angle-adjustable connecting component that can adapt to the construction needs of buildings at different angles, enhance the versatility of the formwork system, reduce customization costs, and improve the flexibility of complex structure construction.

[0023] When the pushing mechanism cancels the pushing of the first spring, the second spring pushes the ring sleeve to slide and reset, so that the traction arm and the clamping arm are reset to a straight line structure, thereby realizing automatic reset of the locking mechanism and reducing the difficulty of disassembly.

Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0044] Example 1

[0045] See also Figures 1-14 The present invention provides a building template, including a template single plate 1 and a connecting piece 2. Adjacent template single plates 1 are assembled and connected by the connecting piece 2. According to actual construction needs, multiple template single plates 1 and a corresponding number of connecting pieces 2 are assembled and spliced ​​to form a template system.

[0046] The formwork veneer 1 is formed of an integral plate body 11 and a frame body 12. The frame body 12 is located on the side of the plate body 11 away from the concrete. In addition, both sides of the connector 2 have circular holders 3. The four sides of the frame body 12 are provided with card holes 13 for the circular holders 3 to be inserted into. The end surface of the circular holder 3 is provided with a locking mechanism 4. When the circular holder 3 is inserted into the card hole 13, Figure 12 As shown, the locking mechanism 4 extends through the locking hole 13 to the inner side of the frame 12 .

[0047] like Figure 8 As shown, the locking mechanism 4 includes a pulling arm 43 and a clamping arm 44. A guide rod 41 is fixed to the end surface of the circular clamping base 3, and a ring sleeve 42 is sleeved on the guide rod 41. The ring sleeve 42 can slide and translate along the length direction of the guide rod 41. A plurality of pulling arms 43 are hingedly mounted on the ring sleeve 42, and a plurality of clamping arms 44 are hingedly mounted on the circular clamping base 3. The pulling arms 43 and the clamping arms 44 are hingedly connected in a one-to-one correspondence.

[0048] Specifically, a plurality of grooves A are arranged in a circular array on one side of the ring sleeve 42 close to the circular card seat 3, and one end of each traction arm 43 is hingedly installed in each groove A through a pin shaft. A plurality of grooves B are arranged in a circular array on one side of the circular card seat 3 close to the ring sleeve 42, and one end of each clamping arm 44 is hingedly installed in each groove B through a pin shaft. The other end of each clamping arm 44 has a groove C, and the other end of each traction arm 43 is hingedly installed in the groove C through a pin shaft.

[0049] The side of the plate 11 that does not contact the concrete is provided with a pushing mechanism 5, which can push the ring sleeve 42 to move toward the side of the circular holder 3. Figure 9 As shown, at this time, the distance between the ring sleeve 42 and the circular clamping seat 3 is reduced. In order to adapt to the change in distance, the connection between the traction arm 43 and the clamping arm 44 is expanded outward. The radial size of the formed protrusion structure is larger than the inner diameter of the clamping hole 13, and then it is in conflict with the port of the clamping hole 13 to achieve a locking effect, which can fix the mold single plate 1 and the connecting part 2.

[0050] It is worth noting that the guide rod 41 is coaxially arranged with the circular card holder 3, the diameter of the guide rod 41 is smaller than the diameter of the circular card holder 3, and the ring sleeve 42 is of the same diameter as the circular card holder 3, so as to ensure that the guide rod 41 and the ring sleeve 42 can smoothly pass through the card hole 13 when the circular card holder 3 is inserted into the card hole 13;

[0051] The guide rod 41 is provided with a first spring 45 on the outside. One end of the first spring 45 is fixed to the ring sleeve 42 and the other end is fixed to the circular holder 3. When the pushing mechanism 5 pushes the ring sleeve 42 to move toward the circular holder 3, Figure 9 As shown, 9 is compressed and stored.

[0052] When the pushing mechanism 5 stops pushing the ring 42, the first spring 45 elastically returns to its original position, pushing the ring 42 to slide and return to its original position. Figure 8 As shown, the pulling arm 43 and the corresponding clamping arm 44 are reset as a whole into a straight line structure, and the distance between the outer surface of the straight line structure and the axis of the circular clamping seat 3 is smaller than the radius of the circular clamping seat 3, ensuring that the pulling arm 43 and the clamping arm 44 can smoothly pass through the clamping hole 13.

[0053] Specifically, when the circular card holder 3 is fully inserted into the card hole 13, the end surface of the circular card holder 3 is located inside the card hole 13, ensuring that the end of each card arm 44 away from the traction arm 43 is located in the card hole 13, so that when the connection between the traction arm 43 and the card arm 44 bulges toward the periphery, Figure 12 As shown, the clamping arm 44 is in contact with the end of the clamping hole 13 to achieve clamping and locking. In addition, as shown in FIG. Figure 13 As shown, each clamping arm 44 is provided with a clamping notch 441 . When clamping and locking, the end of the clamping hole 13 is matched and engaged in the clamping notch 441 , increasing the contact area with the clamping arm 44 and ensuring the stability of the clamping and locking.

[0054] Example 2

[0055] See also Figure 3 、 Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that:

[0056] The pushing mechanism 5 includes a cylindrical rod 52 and a pushing module 6. The pushing module 6 is provided on the plate body 11. The plate body 11 is located on the four sides of the pushing module 6 and is fixed with a mounting seat 51 corresponding to each clamping hole 13. Each mounting seat 51 is provided with a through sliding hole 511. A cylindrical rod 52 is installed in each sliding hole 511, and the cylindrical rod 52 can slide and translate in the sliding hole 511.

[0057] Among them, one end of the cylindrical rod 52 is hollow and the other end is sealed, and the hollow end faces the clamping hole 13. The inner diameter of the hollow part of the cylindrical rod 52 matches the outer diameter of the guide rod 41 to ensure that the end of the guide rod 41 can smoothly enter the hollow end of the cylindrical rod 52;

[0058] The pushing module 6 can push the four cylindrical rods 52 to move toward the side where the clamping hole 13 is located. During this process, the guide rod 41 will enter the hollow end of the cylindrical rod 52 accordingly. As the movement continues, Figure 9 and Figure 12 As shown, the end of the cylindrical rod 52 contacts the ring sleeve 42 and can push the ring sleeve 42 to move toward one side of the circular clamping seat 3, providing an effective pushing force for clamping and locking.

[0059] Example 3

[0060] See also Figure 4 and Figure 5 The difference between this embodiment and embodiment 2 is that:

[0061] The pushing module 6 includes a threaded rod 62 and a conical pushing head 63. A cylindrical seat 61 is fixed to the plate body 11. The outer peripheral wall of the cylindrical seat 61 has side notches 611 at positions corresponding to the positions of the respective mounting seats 51. That is, the side notches 611 correspond to the positions of the respective mounting seats 51 one by one.

[0062] A threaded hole 612 is provided on the end surface of the cylindrical seat 61. The threaded rod 62 is screwed into the threaded hole 612 with matching threads. The conical pushing head 63 is installed on the end of the threaded rod 62 extending into the cylindrical seat 61, with the small-diameter end adjacent to the plate body 11. A first hand wheel 621 is installed on the other end of the threaded rod 62. By holding the first hand wheel 621 and turning the threaded rod 62, the rotating threaded rod 62 can drive the conical pushing head 63 to move and adjust under the action of the threads of the threaded hole 612.

[0063] One end of each cylindrical rod 52 away from the clamping hole 13 extends through the side notch 611 into the cylindrical seat 61 and is respectively fixed with a wedge-shaped extrusion block 64 . Each wedge-shaped extrusion block 64 is extruded and matched with the conical pushing head 63 .

[0064] By screwing and adjusting the threaded rod 62, the conical pushing head 63 is pushed closer to the side of the plate body 11. Under the cooperation of the conical pushing head 63 and the inclined extrusion block 64, each wedge-shaped extrusion block 64 and the cylindrical rod 52 can be pushed as a whole to move toward the side of the clamping hole 13, providing effective drive adjustment for the feeding of each cylindrical rod 52.

[0065] Among them, such as Figure 5 As shown, an annular disk 53 is fixedly mounted on each cylindrical rod 52 between the mounting seat 51 and the wedge-shaped extrusion block 64 , and a second spring 54 is mounted on each cylindrical rod 52 , one end of the second spring 54 is fixed to the annular disk 53 , and the other end is fixed to the mounting seat 51 .

[0066] When the cylindrical rod 52 is fed toward the side of the clamping hole 13, the second spring 54 is compressed and stores force. When the threaded rod 62 is screwed in the opposite direction to drive the conical pushing head 63 to retreat, the cylindrical rod 52 can be driven to retreat under the elastic reset action of the second spring 54 to cancel the pushing of the ring sleeve 42. At this time, under the elastic reset action of the first spring 45, the traction arm 43 and the clamping arm 44 can be driven to reset and retract for disassembly.

[0067] In addition, if Figure 3 and Figure 4 As shown, four auxiliary reinforcing ribs 15 are evenly distributed on the outer peripheral wall of the cylindrical seat 61, and the ends of each auxiliary reinforcing rib 15 are fixed one by one to the four corners of the frame 12. Each auxiliary reinforcing rib 15 is fixed to the plate body 11. The auxiliary reinforcing ribs 15 can be used to reinforce the connection between the plate body 11, the frame body 12 and the cylindrical seat 61 to ensure the stability of the overall structure of the mold single plate 1.

[0068] In addition, it is worth mentioning that when the threaded rod 62 is screwed to drive the cylindrical rod 52 to feed until the locking mechanism 4 is in a clamping and locking state as a whole, since the threaded rod 62 and the threaded hole 612 have a self-locking effect, when not screwing and adjusting, the cylindrical rod 52 can be prevented from retreating and causing the traction arm 43 and the clamping arm 44 to reset, which helps to maintain the clamping and locking state for a long time.

[0069] Example 4

[0070] See also Figure 6 and Figure 7 The difference between this embodiment and embodiment 3 is that:

[0071] The connecting member 2 includes a shaft 22 and two connecting plates 21. The two connecting plates 21 are symmetrically arranged. The shaft 22 is provided on one side of the two connecting plates 21. A connecting arm 23 is fixed to the side end of each connecting plate 21. Each connecting arm 23 is rotatably sleeved on the shaft 22, so that the two connecting plates 21 are rotatably connected to the shaft 22.

[0072] The circular holder 3 is fixed on the surface of the connecting plate 21. The two connecting plates 21 are provided with an adjustment mechanism 7. The adjustment mechanism 7 can drive the two connecting plates 21 to rotate and adjust around the shaft 22 at the same time to adjust the angle between the two connecting plates 21 to adapt to construction with different angles.

[0073] Among them, such as Figure 10 As shown, the adjustment mechanism 7 includes an internally threaded sleeve 71 and a bidirectional screw 73. The two connecting plates 21 are each provided with a mounting groove 211. The internally threaded sleeve 71 is rotatably mounted in the two mounting grooves 211 via a rotating shaft 72. The rotating shaft 72 is arranged parallel to the shaft 22. The internally threaded sleeve 71 is rotatably mounted in the mounting groove 211 by the rotating shaft 72, so that the internally threaded sleeve 71 has the ability to rotate.

[0074] The two internal threaded sleeves 71 are arranged symmetrically, and the bidirectional screw 73 is threadedly matched and installed in the two internal threaded sleeves 71. A second hand wheel 74 is installed at one end of the bidirectional screw 73. By holding the rotating shaft 72 and screwing the bidirectional screw 73, the rotating bidirectional screw 73 can thread-drive the two internal threaded sleeves 71 to move closer to or away from each other. Combined with the connecting plate 21, it is rotatably connected to the shaft 22. When the bidirectional screw 73 rotates forward to drive the two internal threaded sleeves 71 away from each other, the two connecting plates 21 rotate away from each other to achieve angle increase adjustment. Conversely, the angle between the two connecting plates 21 can be reduced.

[0075] Among them, since the internal threaded sleeve 71 can rotate in the installation groove 211, when the two connecting plates 21 are rotated and adjusted, the internal threaded sleeve 71 can adaptively rotate to adapt to the angle change between the two connecting plates 21, avoiding mechanical jamming.

[0076] like Figure 3 、 Figure 7 and Figure 11 As shown, the connecting plate 21 is provided with insertion rods 24 on both sides of the circular holder 3, and the four sides of the frame 12 are provided with insertion holes 14 on both sides of each clamping hole 13 for the insertion rods 24 to match and insert. When the formwork panel 1 is assembled on the side of the connector 2, the insertion rods 24 are inserted into the insertion holes 14 to further provide clamping support, thereby ensuring the firmness of the connection between the formwork panel 1 and the connector 2, thereby effectively improving the overall resistance to concrete pressure.

[0077] Example 5

[0078] This embodiment takes the need to assemble four mold single plates 1 into a whole as an example. Figure 14 As shown, by setting a connector 2 between two adjacent mold single plates 1, and utilizing the circular holder 3 and locking mechanism 4 on the connector 2 and the pushing mechanism 5 on the mold single plate 1, the four mold single plates 1 can be clamped and locked together to form a stable template system.

[0079] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
