Description

Technical Field

[0001] This utility model belongs to the field of building formwork technology, specifically relating to a retractable formwork for elevator shafts. Background Technology

[0002] When constructing a cast-in-place concrete wall in an elevator shaft, a formwork frame needs to be erected inside the elevator shaft. After the formwork frame is erected, concrete is poured outside the formwork frame to prevent concrete from entering the elevator shaft. The formwork frame is then removed after the concrete has completely solidified, thus completing the construction of the cast-in-place concrete wall in the elevator shaft.

[0003] The existing construction method for elevator shaft formwork frames involves overlapping several wooden or metal formwork panels. However, since the structure of the existing wooden or metal formwork panels is fixed and cannot be adjusted, the structure of the elevator shaft formwork frame formed by overlapping several fixed formwork panels also cannot be adjusted. As a result, when dismantling the elevator shaft formwork frame, workers can only enter the narrow and dangerous elevator shaft to dismantle the formwork panels one by one, which is slow, especially for high-rise buildings, where the turnover is even slower. Utility Model Content

[0004] To address the technical problem that existing templates have a fixed structure and cannot be adjusted, the purpose of this utility model is to provide a retractable template for elevator shafts, wherein the distance between the two side panels of the template can be adjusted.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a retractable template for elevator shaft, including a main board, two side plates located on the same side of the main board and arranged opposite to each other, and a slide rod slidably connected to the main board and located between the two side plates. The slide rod slides along the length of the main board and is movably connected to the two side plates. The sliding slide rod will drive the two side plates to move towards each other and away from each other.

[0006] In the above solution, by providing a slide bar and two side plates on the same side of the main board, and the slide bar being movably connected to the two side plates, when the slide bar is slid upward, it will drive the two side plates to move closer to each other to a contracted state, thereby reducing the distance between the two side plates; while when the slide bar is slid downward, it will drive the two side plates to move further apart to an expanded state, thereby increasing the distance between the two side plates and allowing the two side plates to return to their original position, thus realizing the structural function of adjustable distance between the two side plates.

[0007] Furthermore, the aforementioned sliding rod is provided with guide blocks on the two side walls opposite to the two side plates, and connecting plates are provided on the inner side of the two side plates. The connecting plates have guide grooves, and guide rods are provided on the side walls of the guide blocks. The guide rods are placed in the guide grooves. Sliding the sliding rod will cause the guide rods to slide along the guide grooves, thereby transmitting power to the two side plates to move closer to each other and further away from each other. Specifically, when the sliding rod is slid upward, it will cause the guide rods to slide upward along the guide grooves, and at the same time, the guide rods will push the side walls of the guide grooves, causing the two side plates to move closer together, thereby reducing the distance between the two side plates. When the sliding rod is slid downward, it will cause the guide rods to slide downward along the guide grooves, and at the same time, the guide rods will push the side walls of the guide grooves, causing the two side plates to move further away from each other, thereby increasing the distance between the two side plates.

[0008] Furthermore, the aforementioned guide block has a hollow structure with a through hole. The guide rod passes through the through hole, and pins are inserted into the side wall of the guide rod corresponding to the two inner side walls of the guide block. This facilitates the assembly and disassembly of the guide rod. The two pins prevent the guide rod from moving back and forth along the through hole, ensuring the stability of the guide rod installation. After pulling out the two pins, the guide rod can be pulled out of the through hole.

[0009] Furthermore, the aforementioned guide blocks are detachably connected to the slide rod via a connecting assembly, which includes bolts and nuts. The right end of the bolt passes through the side walls of the two guide blocks and the slide rod in sequence and is threadedly connected to the nut, thereby connecting the two guide blocks and the slide rod. The connection is stable and facilitates the assembly and disassembly of the guide blocks and the slide rod.

[0010] Furthermore, the two side plates mentioned above are provided with connecting plates on opposite sides of the guide block. The guide block is placed between the two connecting plates of the corresponding side plate, and the side plate and the main plate are in contact with each other. This allows the two side plates to move more smoothly in the direction of moving away from each other and towards each other.

[0011] Furthermore, the main board is provided with a sliding sleeve at the position of the sliding rod, and the sliding rod is slidably fitted into the sliding sleeve so that the sliding rod can slide up and down along the sliding sleeve, thereby realizing the structural function that the sliding rod can slide along the length direction of the main board.

[0012] Furthermore, the aforementioned retractable formwork for elevator shafts also includes a limiting component to restrict the sliding of the slide bar. The limiting component restricts the natural sliding of the slide bar, thereby ensuring the structural stability of the formwork.

[0013] Furthermore, the sliding sleeve and sliding rod sidewalls are provided with insertion holes, and the limiting member is an insertion rod. When the sliding rod drives the two side plates to move to the expanded state, the insertion holes of the sliding sleeve and the sliding rod are aligned. At this time, the insertion rod can be inserted into and disengaged from the insertion holes of the sliding sleeve and the sliding rod. In use, when the insertion rod is inserted into the insertion holes of the sliding sleeve and the sliding rod, the sliding rod cannot slide due to the obstruction of the insertion rod, thereby locking the two side plates in the expanded state. When the insertion rod is pulled out of the insertion holes of the sliding sleeve and the sliding rod, the restriction on the sliding rod is released, allowing the sliding rod to slide upwards and drive the two side plates to move closer to each other, thereby reducing the distance between the two side plates.

[0014] Furthermore, the aforementioned motherboard side is provided with reinforcing blocks on both sides corresponding to the sliding sleeve. The reinforcing blocks are located between the two side plates, and the reinforcing blocks can improve the structural stability of the motherboard.

[0015] Furthermore, the upper side wall of the slide bar is provided with a lifting hole. When in use, the hook of the crane can be hooked into the lifting hole, and then the slide bar can be lifted by the crane. This makes it easy to lift the slide bar and slide it upward to reduce the distance between the two side plates.

[0016] The retractable elevator shaft template of this invention features an adjustable distance between its two side panels. Sliding the operating slide rod upwards causes the guide rod to slide upwards along the guide groove, reducing the distance between the two side panels. Conversely, sliding the operating slide rod downwards causes the guide rod to slide downwards along the guide groove, increasing the distance between the two side panels. This design is easy to operate. In use, this retractable template can be overlapped with other templates to form an elevator shaft template frame. When dismantling the template frame, the slide rod can be lifted and slid upwards to reduce the distance between the two side panels, thus reducing the overall size of the template frame. This allows the reduced template frame to be easily lifted out of the elevator shaft or raised to the next floor, making construction convenient and efficient. Furthermore, the insert rod can restrict the upward sliding of the slide rod, locking the two side panels in the expanded state and preventing the distance between them from automatically decreasing, ensuring the structural stability of the retractable template. Pulling the insert rod out of the sliding sleeve and the insertion hole of the slide rod releases the restriction, making unlocking convenient. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1 like Figure 1 , 2 As shown, this embodiment provides a retractable elevator shaft template, including a main board 1, two side panels 2 located on the front side of the main board 1 and arranged opposite each other, and a slide rod 3 slidably connected to the main board 1 and located between the two side panels 2. The slide rod 3 slides along the length of the main board 1, and the slide rod 3 is movably connected to the two side panels 2. The sliding slide rod 3 is driven by the two side panels 2 to move closer to each other and further away from each other. Wherein, as Figure 2As shown, when the slider 3 is slid upwards, it will cause the two side plates 2 to move closer to each other until they retract, thereby reducing the distance between the two side plates 2; and as Figure 1 As shown, when the sliding rod 3 is slid down, it will drive the two side plates 2 to move away from each other to an expanded state, thereby increasing the distance between the two side plates 2 and allowing the two side plates 2 to return to their original position, thus realizing the structural function of adjustable distance between the two side plates 2.

[0026] Specifically, in order to realize the structural function of sliding the aforementioned slide rod 3, which transmits power to the two side plates 2 to move closer to and further away from each other, as follows: Figure 3 As shown, the slide bar 3 has guide blocks 31 on its left and right side walls, and connecting plates 21 are provided on the inner sides of the two side plates 2. The connecting plates 21 have guide grooves 210, which are arc-shaped and symmetrical. Guide rods 32 are provided on the side walls of the guide blocks 31 and are placed within the guide grooves 210. Sliding the slide bar 3 will cause the guide rods 32 to slide along the guide grooves 210, thus transmitting power to the two side plates 2 to move closer to each other and further away. Figure 2 As shown, when the slider 3 is slid upward, it will cause the guide rod 32 to slide upward along the guide groove 210. At the same time, the guide rod 32 will push the side wall of the guide groove 210, causing the two side plates 2 to move closer together to a retracted state, thereby reducing the distance between the two side plates 2; Figure 1 As shown, when the slide bar 3 is slid down, it will drive the guide bar 32 to slide down along the guide groove 210. At the same time, the guide bar 32 will push the side wall of the guide groove 210 to move the two side plates 2 away from each other to the expanded state, thereby increasing the distance between the two side plates 2 and making the two side plates 2 reset.

[0027] The retractable template of this embodiment has a sliding rod 3 and two side plates 2 on the front side of the main board 1. The sliding rod 3 is movably connected to the two side plates 2. The sliding rod 3 can drive the two side plates 2 to move to the retracted and expanded state, thereby realizing the structural function of adjustable distance between the two side plates 2, which solves the technical problem of the existing template structure being fixed and unable to be adjusted.

[0028] Example 2 This embodiment is a further improvement on the structure of the retractable formwork for the elevator shaft in Embodiment 1. The improvement lies in that, as Figure 4As shown, the guide block 31 is a hollow structure. The guide block 31 has a through hole 310 that passes through its front and rear side walls. The guide rod 32 passes through the through hole 32. The side wall of the guide rod 32 is fitted with pins 33 corresponding to the two inner side walls of the guide block 31. The two pins 33 abut against the corresponding inner side wall of the guide block 31. This facilitates the installation and removal of the guide rod 32. The two pins 33 can prevent the guide rod 32 from moving back and forth along the through hole 32, ensuring the installation stability of the guide rod 32. After pulling out the two pins 33, the guide rod 32 can be pulled out of the through hole 310. In addition, the guide block 31 is detachably connected to the slide rod via a connecting assembly. Specifically, the connecting assembly includes a bolt 41 and a nut 42. The right end of the bolt 41 passes through the side wall of the two guide blocks 31 and the slide rod 3 and is threadedly connected to the nut 42, thereby connecting the two guide blocks 31 and the slide rod 3. The connection is stable and facilitates the disassembly and assembly of the guide block 31 and the slide rod 3.

[0029] like Figure 1 , 3 As shown, two guide blocks 31 are evenly distributed along the length of the left and right sides of the slide bar 3. The two side plates 2 are provided with connecting plates 21 on opposite sides of the guide blocks 31. The guide blocks 31 are positioned between the two connecting plates 21 on the corresponding side plates 2, and the rear side of the side plate 2 is in contact with the front side of the main plate 1. This allows the two side plates 2 to move more smoothly in the direction of moving away from each other and towards each other.

[0030] The front side of the aforementioned motherboard 1, corresponding to the position of the slide rod 3, is provided with a sliding sleeve 11. The slide rod 3 slides within the sliding sleeve 11, allowing it to slide up and down along the sleeve 11, thus achieving the structural function of the slide rod 3 sliding along the length of the motherboard 1. Specifically, there are three sliding sleeves 11, evenly arranged along the length of the motherboard 1, which improves the installation stability of the slide rod 3 and makes the sliding more stable. The sliding sleeves 11 facilitate the sliding connection between the slide rod 3 and the motherboard 1. When it is necessary to disassemble the slide rod 3, the two guide blocks 31 can be detached from the slide rod 3, allowing the slide rod 3 to slide out of the sliding sleeve 11, thus facilitating the assembly and disassembly of the slide rod 3 and the motherboard 1. Furthermore, the front side of the aforementioned motherboard 1, corresponding to the left and right sides of the sliding sleeve 11, is provided with reinforcing blocks 12. The reinforcing blocks 12 are located between the two side plates 2, and these reinforcing blocks 12 improve the structural stability of the motherboard 1.

[0031] like Figure 1 As shown, the lengths of the main board 1, side plate 2, and slide bar 3 are equal, and the upper and lower ends of the side plates 2 are flush with the upper and lower ends of the main board 1. The side plates 2 are parallel to the slide bar 3. When the lower end of the slide bar 3 is flush with the lower end of the main board 1 and the side plate 2, the side plates 2 are in an expanded state. At the same time, the guide rod 32 abuts against the lower end of the guide groove 210. At this time, the lower side wall of the guide groove 210 will block the slide bar 3 from sliding down further, thus preventing the slide bar 3 from sliding down excessively.

[0032] Example 3 This embodiment is a further improvement on the structure of the retractable formwork for the elevator shaft in Embodiment 2. The improvement lies in that, as Figure 1 , 3 As shown, the above-mentioned retractable formwork for elevator shafts also includes a limiting component for restricting the sliding of the slide bar 3. The limiting component restricts the natural sliding of the slide bar 3, thereby ensuring the structural stability of the formwork.

[0033] Specifically, the side wall of the sliding sleeve 11 and the side wall of the sliding rod 3, which are located in the middle, are provided with insertion holes 50. The insertion holes 50 pass through the left and right sides of the sliding sleeve 11 and the sliding rod 3. The limiting member is the insertion rod 5. When the sliding rod 3 is driven by the two side plates 2 to move to the expanded state, the insertion holes 50 of the sliding sleeve 11 and the insertion holes 50 of the sliding rod 3 are aligned. At this time, the insertion rod 5 can be inserted into and disengaged from the insertion holes 50 of the sliding sleeve 11 and the sliding rod 3.

[0034] When using, such as Figure 1 As shown, the downward sliding rod 3 drives the two side plates 2 to move to the expanded state, so that the insertion hole 50 of the sliding sleeve 11 is aligned with the insertion hole 50 of the sliding rod 3. When the insertion rod 5 is inserted into the insertion hole 50 of the sliding sleeve 11 and the sliding rod 3, the sliding rod 3 cannot slide due to the obstruction of the insertion rod 5, thus locking the two side plates 2 in the expanded state and ensuring the structural stability of the template. Figure 2 As shown, when the insert rod 5 is pulled out of the insertion hole 50 of the sliding sleeve 11 and the sliding rod 3, the restriction on the sliding rod 3 can be released, so that the sliding rod 3 can slide upward to drive the two side plates 2 to move towards each other to the retracted state, so as to reduce the distance between the two side plates 2.

[0035] As an improvement to this embodiment, such as Figure 2 As shown, the upper side wall of the slide bar 3 is provided with a lifting hole 30. When in use, the hook of the crane can be hooked into the lifting hole 30, and then the slide bar 3 can be lifted by the crane. In this way, the slide bar 3 can be easily lifted and slid upward to reduce the distance between the two side plates 2.

[0036] When using the retractable formwork for elevator shafts of this utility model, such as Figure 5 As shown, four retractable templates of this embodiment can be overlapped with other existing templates to form an elevator shaft template frame. When dismantling the template frame, the insert rod 5 can be pulled out to release the sliding restriction on the slide rod 3. Then, the slide rod 3 can be lifted by a crane and slid upward to reduce the distance between the two side plates 2, thereby reducing the overall structure of the template frame. In this way, the reduced template frame can be easily lifted out of the elevator shaft or raised to the next floor for use. The construction is convenient and the work efficiency is high.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
