Description

Technical Field

[0001] This utility model relates to the field of cantilever formwork technology, specifically a spliced ​​concrete cantilever formwork. Background Technology

[0002] In concrete pouring operations for different structures such as bridge piers and building construction, formwork components are often used in conjunction with climbing formwork devices to enable formwork to operate at different heights.

[0003] First, the preparatory work involves assembling the template. Several supporting wooden blocks are laid on the ground, and then a template body is laid flat on top. Several I-beams are then placed at equal intervals on the template body. Both the template body and the I-beams are wooden structures and are usually fixed together with screws for long-term use. Finally, several back braces are laid at equal intervals on the I-beams. The equidistant distribution of the back braces ensures that the I-beams and the template body are subjected to more even stress, preventing damage due to uneven stress. Connecting claws are used to fix the I-beams and back braces together, and one template component is assembled.

[0004] In the existing technology, it is necessary to first measure the partitions of the I-beam to obtain the pre-placement position of the back beam. After placing a back beam in the pre-placement position, the connecting claw on it needs to be installed in time to avoid accidental contact that causes the back beam to shift position and requires time to reposition, which delays the splicing of the template components. Utility Model Content

[0005] The purpose of this invention is to provide a spliced ​​concrete cantilever formwork to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spliced ​​concrete cantilever formwork, comprising a formwork body, wherein a plurality of I-beams are equidistantly distributed on one side of the formwork body, and a plurality of rows of back ribs are equidistantly distributed and intersected on the plurality of I-beams, wherein an auxiliary component capable of being unfolded and retracted is provided between two adjacent back ribs for controlling the distance between the plurality of back ribs, wherein the I-beams are connected to the back ribs via connecting claws, and the auxiliary component includes a pivot and two connecting rods rotatably connected at their ends via the pivot; one of the two connecting rods includes a connecting rod one rotatably connected to the edge of the previous back rib, and a connecting rod two rotatably connected to the edge of the next back rib.

[0007] Furthermore, the first connecting rod is shorter than the second connecting rod, and the first connecting rod is provided with a "I" block. When the first connecting rod and the second connecting rod are unfolded to form a straight line, the "I" block is parallel to the second connecting rod.

[0008] Furthermore, the connecting rod is provided with a symmetrical locking block one and a locking block two at the end away from the rotating shaft, and two elastic slots with different opening directions are provided on the edge of the back rib on the rotation trajectory of the corresponding locking blocks; of the two elastic slots, elastic slot one is matched with locking block one and elastic slot two is matched with locking block two.

[0009] Furthermore, it also includes a core strip and a steel pin; when splicing two template bodies, the front and rear back ribs in the same row are aligned, and the two back ribs in the same row are connected by a core strip; the core strip is provided with slot one at equal intervals, the back rib is provided with slot two at equal intervals, and the steel pin passes through one of the slots one and slot two that are aligned with each other in the vertical direction.

[0010] Furthermore, it also includes a rope, and the steel pin is provided with a through hole one and a through hole two; one end of the rope passes through the through hole one of the steel pins in the same row in sequence, and then passes through the through hole two of the steel pins in the same row in reverse sequence, and is then fixed together with the other end of the rope.

[0011] Furthermore, it also includes a connecting plate, one side of which is coplanar with the template body, and the other side of which is provided with a pad, and the pad is provided with a U-shaped hanging ring; when splicing two template bodies, the U-shaped hanging ring passes through the gap in the middle of the core strip, and the steel pin passes through one of the sets of slot one, slot two and U-shaped hanging ring that are aligned with each other in the vertical direction.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention allows for the simultaneous installation of multiple back ribs at equal intervals in a single operation. The equidistant distribution of the back ribs ensures more even stress distribution on the I-beams and the formwork body. Two connecting claws are first installed along two opposite corners of the formwork body, thus pre-fixing the auxiliary components and back ribs. At this point, a significant external force is required to change the positions of the auxiliary components and back ribs. Normal force will not change the position of the back ribs, reducing the number of position adjustments during installation and allowing for more precise and rapid adjustment of all auxiliary components to the same angle. Several steel pins in the same row are fixed to a rope, mutually restraining each other for easy disassembly and transportation, preventing them from falling or accidentally injuring others during use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figures 1-4 .

[0021] This utility model provides a spliced ​​concrete cantilever formwork, including a formwork body 1. Several I-beams 2 are evenly distributed on one side of the formwork body 1. Several rows of back ribs 3 are evenly distributed and intersected on the several I-beams 2. An auxiliary component that can be unfolded and retracted is provided between two adjacent back ribs 3 to control the distance between the several back ribs 3. The I-beams 2 are connected to the back ribs 3 through connecting claws 4. The auxiliary component includes a rotating shaft 5 and two connecting rods whose ends are rotatably connected through the rotating shaft 5. The two connecting rods include a connecting rod 6 that is rotatably connected to the edge of the previous back rib 3, and a connecting rod 7 that is rotatably connected to the edge of the next back rib 3.

[0022] Furthermore, the first connecting rod 6 is shorter than the second connecting rod 7, and the first connecting rod 6 is provided with a block 8. When the first connecting rod 6 and the second connecting rod 7 are unfolded to form a straight line, the block 8 is parallel to the second connecting rod 7.

[0023] Specifically, the connecting rod is provided with symmetrical locking blocks 9 and 10 at the end away from the rotating shaft 5, and two elastic slots with different opening directions are provided on the edge of the back rib 3 on the rotation trajectory of the corresponding locking blocks; of the two elastic slots, the elastic slot 11 is matched with the locking block 9, and the elastic slot 12 is matched with the locking block 10.

[0024] Furthermore, it also includes a core strip 13 and a steel pin 14; when splicing two template bodies 1, the front and rear back ribs 3 in the same row are aligned, and the two back ribs 3 in the same row are connected by the core strip 13; the core strip 13 is provided with slot one 15 at equal intervals, the back rib 3 is provided with slot two 16 at equal intervals, and the steel pin 14 passes through one of the slot one 15 and slot two 16 that are aligned with each other in the vertical direction.

[0025] In one embodiment, the system further includes a rope, wherein the steel pin 14 is provided with a through hole 17 and a through hole 18; one end of the rope passes through the through hole 17 of the steel pin 14 in the same row in sequence, and then passes through the through hole 18 of the steel pin 14 in the same row in reverse sequence, and is then fixed together with the other end of the rope.

[0026] Preferably, it also includes a connecting plate 19, one side of which is coplanar with the template body 1, and the other side of which is provided with a pad 20. The pad 20 is provided with a U-shaped hanging ring 21. When splicing two template bodies 1, the U-shaped hanging ring 21 passes through the gap in the middle of the core strip 13, and the steel pin 14 passes through one of the sets of slots 15 and 16 that are aligned with each other in the vertical direction and the U-shaped hanging ring 21.

[0027] In use, several supporting wooden blocks are placed on the ground to prevent scratches from direct contact with the formwork body and to facilitate lifting the formwork body. Then, one side of the formwork body is laid flat on the supporting wooden blocks, with several pre-fixed, equidistantly laid I-beams 2 on one side. Several back beams 3, connected by auxiliary components, are laid flat on the I-beams 2. Simultaneously, the two outermost back beams 3 are pulled outwards, and the force is transmitted between the connected auxiliary components and the back beams 3. This unfolds several auxiliary components between adjacent back beams 3, all unfolding to the same size, thus controlling the spacing between adjacent back beams 3 to be equal. Multiple back ribs 3 are installed at equal intervals in a single operation. The equidistant distribution of the back ribs 3 makes the force on the I-beam 2 and the formwork body more even. At least two connecting claws 4 are taken, one fixed to the upper left of the suspended formwork body and the other fixed to the lower right of the suspended formwork body. The edge of the I-beam 2 is connected to the edge of the back rib 3 through the connecting claws 4. The two connecting claws 4 are first installed along the two opposite corners of the formwork body, which completes the pre-fixation of the auxiliary parts and back ribs 3. At this time, a large external force is required to change the position of the auxiliary parts and back ribs 3. Normal force will not change the position of the back ribs 3, reducing the number of position adjustments during the installation process.

[0028] Furthermore, during the unfolding of the auxiliary components, the connecting rod rotates forward. The end of the connecting rod near the pivot 5 gradually moves away from the edge of the back rib 3 where the connecting rod is located, until connecting rod 6 and connecting rod 7 form a straight line. At this point, connecting rod 7 cannot continue to rotate forward due to the restriction of the slotted block 8 on connecting rod 6. During the rotation process, the end of the connecting rod away from the pivot 5 drives the locking block 9 to engage with the elastic slot 11. Through the restriction of the locking block, the elastic slot 11, and the slotted block 8, all auxiliary components can be adjusted to the same angle more accurately and quickly. The method of using the connecting claw 4 is relatively simple in existing technology, so it will not be described in detail.

[0029] When two templates need to be joined together during construction, if there is no gap between them, align the two templates, aligning each row of back ribs 3 on the left and right sides. Insert a core strip 13 between two back ribs 3 in the same row, aligning the slot 15 of the core strip 13 with the slot 26 on the back rib 3. Take a steel pin 14 and pass it through one set of slots 15 and slot 26 that are aligned vertically. Similarly, insert several steel pins 14 to complete the fixation. If there is a gap between the two templates, place a connecting plate 19 in the gap, so that the left template and the connecting plate 19 are aligned. Aligning with the template body on the right, insert a core strip 13 between the two back ribs 3 in the same row. One end of the core strip 13 is inserted into the back rib 3 on the left, and the other end of the core strip 13 is inserted into the back rib 3 on the right. The U-shaped hanging ring on the connecting plate 19 passes through the gap in the middle of the core strip 13. Finally, at the part where the core strip 13 overlaps with the back rib 3, the steel pin 14 passes through one set of slot 15 and slot 2 16 that are aligned with each other in the vertical direction. At the part where the core strip 13 overlaps with the U-shaped hanging ring, the steel pin 14 passes through one set of slot 15, slot 2 16 and U-shaped hanging ring that are aligned with each other in the vertical direction. Similarly, insert several steel pins 14 in the corresponding positions.

[0030] When the back ribs 3 need to be disassembled after construction is completed, first remove all the connecting claws 4, then push the two outermost back ribs 3 inward simultaneously or sequentially, so that the main locking block disengages from the slot 15. The end of the connecting rod near the pivot 5 gradually approaches the edge of the back rib 3 where the connecting rod is located, and the included angle between the two connecting rods connected by the same pivot 5 gradually decreases. Connecting rod 1 6 is shorter than connecting rod 2 7, which facilitates better retraction and fitting of connecting rod 1 6 and connecting rod 2 7.

[0031] During the insertion and removal of the steel pins 14, a significant external force is required to securely connect them to slot 15 or slot 2 16. Using a hammer would cause excessive force, potentially causing the pins to fly out and injure others. Furthermore, a single set of pins 14 is inconvenient to handle and move. Therefore, a rope is used. One end of the rope passes sequentially through the through-hole 17 of the pins 14 in the same row, and then sequentially through the through-hole 18 of the pins 14 in the same row, before being fixed to the other end of the rope. This secures the pins 14 in the same row to a single rope, providing mutual restraint for easy disassembly and handling, and preventing them from falling or injuring others during use. Two through-holes (17 and 18) are provided on each pin 14, instead of just one, because the two through-holes allow for the organization and restraint of the rope, preventing it from becoming too tangled and hindering the construction process.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0033] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0034] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more.

[0035] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of the utility model.
