[0003]现有快拆模架虽能实现顶板高度调节和支撑面积的扩展，但普遍将两项功能拆分为独立操作模块，现有模架调节顶板高度时，需依赖单独的升降组件驱动顶板移动，而支撑板的向外拓展则需通过另一组驱动机构或人工手动操作实现，这种分步调节模式存在显著弊端：施工人员需在高空环境下先调节顶板高度以固定模板至预设位置，再单独操作扩展支撑面积，工序繁琐且耗时，大幅降低施工效率；高空操作过程中，模板的存在会进一步限制施工空间，增加支撑板支撑面积调节的操作难度，易因操作误差导致拓展板伸出长度不均，反而影响模架整体支撑平衡，为此，我们提出一种多高层建筑楼面施工用可调式快拆模架

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically, it relates to an adjustable quick-release formwork for the construction of multi-story and high-rise building floors. Background Technology
[0002] In the construction of multi-story and high-rise buildings, concrete pouring relies on formwork to form a pre-set space. Adjustable quick-release formwork serves as the core support carrier for the formwork. The core function of its top plate is to fix the formwork body and ensure that the formwork maintains a stable position and shape during the pouring process. Therefore, the height adjustment accuracy and support stability of the top plate directly determine the quality and safety of the floor construction. As multi-story and high-rise buildings develop towards large spans and high altitudes, the adaptability requirements of the formwork for floor construction have significantly increased. It is not only necessary to flexibly adjust the height of the top plate according to different floor elevations to accurately position the formwork, but also to balance the pressure brought by the formwork and the pouring load by expanding the support area to avoid the formwork becoming unstable due to the upward shift of the center of gravity.
[0003] While existing quick-release formwork can achieve both top plate height adjustment and support area expansion, these two functions are generally separated into independent operation modules. Adjusting the top plate height requires a separate lifting component to drive the plate movement, while extending the support plate requires another driving mechanism or manual operation. This step-by-step adjustment mode has significant drawbacks: construction workers must first adjust the top plate height to fix the formwork to the preset position in a high-altitude environment, and then separately operate to expand the support area. This process is cumbersome and time-consuming, significantly reducing construction efficiency. During high-altitude operations, the presence of the formwork further restricts the construction space, increases the difficulty of adjusting the support plate's support area, and is prone to uneven extension lengths due to operational errors, which in turn affects the overall support balance of the formwork. Therefore, we propose an adjustable quick-release formwork for multi-story building floor construction. Utility Model Content
[0004] This utility model provides an adjustable quick-release formwork for the construction of multi-story and high-rise building floors, in order to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adjustable quick-release formwork for multi-story building floor construction includes a support rod located in the middle of a cross-shaped stabilizing plate. Each intersecting edge of the cross-shaped stabilizing plate has an extension plate horizontally slidably connected inside. A drive mechanism is mounted on the support rod, and the drive mechanism is connected to each extension plate via a first transmission mechanism. A lifting sleeve coaxial with the support rod is mounted at the upper end of the drive mechanism, and the drive mechanism is connected to the lifting sleeve via a second transmission mechanism. A top plate is fixedly connected to the top of the lifting sleeve, and a formwork body is fixedly mounted on the top plate. Activating the drive mechanism causes the extension plates to slide outward via the first transmission mechanism and the lifting sleeve to move upward via the second transmission mechanism, thereby increasing the support area of the cross-shaped stabilizing plate and the height of the top plate.
[0006] Furthermore, a short shaft is coaxially fixedly connected to the bottom end of the support rod, and the short shaft is coaxially rotatably connected to the rotating cavity in the middle of the cross stabilizer plate. A through hole communicating with the rotating cavity is opened in the middle of the bottom end of the cross stabilizer plate, and four anchoring nails are arranged in the through hole at intervals along its circumference. The anchoring nails are fixedly connected to the bottom end of the short shaft.
[0007] Furthermore, the first transmission mechanism includes a threaded sleeve coaxially sleeved on the outside of the support rod. The support rod is a threaded rod and is threadedly connected to the threaded sleeve. The side wall of the threaded sleeve is provided with four hinged rods spaced apart along its circumference. The upper end of each hinged rod is hinged to the side wall of the threaded sleeve, and the lower end of each hinged rod is hinged to the top of each extension plate.
[0008] Furthermore, the driving mechanism includes a rotating sleeve coaxially rotatably connected to the top of the support rod, and four sliding rods spaced apart along its circumference are fixedly connected to the bottom of the rotating sleeve. The sliding rods pass downward through the threaded sleeve and are slidably connected to it.
[0009] Furthermore, the second transmission mechanism includes a transmission screw coaxially fixedly connected to the top of the rotating sleeve, the lifting sleeve having an internal thread, and the lifting sleeve being threadedly connected to the transmission screw.
[0010] Furthermore, a groove is provided at the bottom end of the cross-shaped rib plate, and the extension plate is horizontally slidably connected within the groove.
[0011] Furthermore, the outer end of the expansion plate is integrally formed with a fixing plate, and the fixing plate has a through positioning screw hole.
[0012] The technological advancements achieved by this invention compared to existing technologies, due to the aforementioned structure, are as follows: During use, the cross-shaped stabilizing plate is first placed at the designated construction position, and the drive mechanism mounted on the support rod is activated. The drive mechanism transmits power to the extension plates within each intersecting edge of the cross-shaped stabilizing plate via a first transmission mechanism, causing each extension plate to slide horizontally outward along the intersecting edge. Simultaneously, the drive mechanism transmits power to the lifting sleeve coaxial with the support rod via a second transmission mechanism, causing the lifting sleeve to move axially upward along the support rod. The top plate fixed at the top of the lifting sleeve rises synchronously with the lifting sleeve, thereby driving the fixed installation on the top plate... The template body is raised, ultimately achieving a simultaneous increase in the support area of the cross-shaped stabilizing plate and a simultaneous increase in the height of the top plate. This utility model realizes the synchronous linkage between the expansion of the support area and the increase in the height of the top plate, eliminating the need to operate two sets of mechanisms separately, greatly simplifying the construction process, reducing high-altitude work steps, and improving construction efficiency. When the height of the top plate is increased, the support area is expanded simultaneously, which can effectively balance the center of gravity of the formwork after the top plate and the template body are raised, avoiding the swaying or overturning of the formwork due to the upward shift of the center of gravity and insufficient support area, significantly enhancing the stability of the formwork support, ensuring the stability of the template body during the concrete pouring process, and improving the quality of floor construction.

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0017] This utility model discloses an adjustable quick-release formwork for the construction of floors in multi-story and high-rise buildings, such as... Figure 1-4 As shown, the system includes a support rod 2 located in the middle of the cross-shaped stabilizing plate 1. Each cross-shaped rib plate 101 of the cross-shaped stabilizing plate 1 is horizontally slidably connected to an extension plate 3. A drive mechanism is provided on the support rod 2. The drive mechanism is connected to each extension plate 3 via a first transmission mechanism. A lifting sleeve 4 is provided at the upper end of the drive mechanism. The lifting sleeve 4 is coaxially arranged with the support rod 2. The drive mechanism is connected to the lifting sleeve 4 via a second transmission mechanism. A top plate 5 is fixedly connected to the top of the lifting sleeve 4. A template body is fixedly installed on the top plate 5. When the drive mechanism is activated, each extension plate 3 is slid outward through the first transmission mechanism, and the lifting sleeve 4 is moved upward through the second transmission mechanism, thereby increasing the support area of the cross-shaped stabilizing plate 1 and increasing the height of the top plate 5. The working principle and advantages of this utility model are as follows: When using this adjustable quick-release formwork frame, first place the cross stabilizing plate 1 at the designated construction position, and then activate the drive mechanism set on the support rod 2; the drive mechanism transmits power to the extension plates 3 in each cross rib 101 of the cross stabilizing plate 1 through the first transmission mechanism, causing each extension plate 3 to slide horizontally outward along the cross rib 101; at the same time, the drive mechanism transmits power to the lifting sleeve 4 coaxial with the support rod 2 through the second transmission mechanism, causing the lifting sleeve 4 to move upward along the axial direction of the support rod 2; the top plate 5 fixed at the top of the lifting sleeve 4 rises synchronously with the lifting sleeve 4, thereby driving the fixed installation on the top plate 5 to rise synchronously. The installation of the formwork body is raised, ultimately achieving a simultaneous increase in the support area of the cross-stabilizing plate 1 and the height of the top plate 5. This utility model realizes the synchronous linkage between the expansion of the support area and the increase in the height of the top plate 5, eliminating the need to operate two sets of mechanisms separately, greatly simplifying the construction process, reducing high-altitude work steps, and improving construction efficiency. When the height of the top plate 5 is raised, the support area is expanded simultaneously, which can effectively balance the center of gravity of the formwork after the top plate 5 and the formwork body are raised, avoiding the shaking or overturning of the formwork due to the upward shift of the center of gravity and insufficient support area, significantly enhancing the stability of the formwork support, ensuring the stability of the formwork body during the concrete pouring process, and improving the quality of floor construction.
[0018] In a preferred embodiment of this utility model, a short shaft 6 is coaxially fixedly connected to the bottom end of the support rod 2. The short shaft 6 is coaxially rotatably connected to the rotating cavity in the middle of the cross-shaped stabilizing plate 1. A through hole 7 communicating with the rotating cavity is opened in the middle of the bottom end of the cross-shaped stabilizing plate 1. Four anchoring nails 8 are arranged circumferentially spaced in the through hole 7. The anchoring nails 8 are fixedly connected to the bottom end of the short shaft 6. The bottom end of the support rod 2 achieves rotational cooperation with the cross-shaped stabilizing plate 1 through the short shaft 6 coaxially fixedly connected. The short shaft 6 is coaxially rotatably connected to the pre-set rotating cavity in the middle of the cross-shaped stabilizing plate 1. In the initial stage of construction, it can be opened through the short shaft 6. By rotating the support rod 2, the short shaft 6 is driven to rotate synchronously within the rotating cavity, thereby adjusting the angle of the support rod 2 so that the top plate 5 and the formwork body can adapt to the spatial layout or elevation requirements of the construction area. After the angle of the support rod 2 is adjusted to the preset position, the four anchor nails 8, which are distributed circumferentially in the through hole 7 at the bottom center of the cross stabilizing plate 1 and communicate with the rotating cavity, are fixed to the ground. The firm connection between the anchor nails 8 and the ground restricts the rotation of the short shaft 6 within the rotating cavity, thereby fixing the support rod 2 and preventing it from rotating or shifting during subsequent construction.
[0019] In a preferred embodiment of this utility model, the first transmission mechanism includes a threaded sleeve 9 coaxially sleeved on the outside of the support rod 2. The support rod 2 is a threaded rod and is threadedly connected to the threaded sleeve 9. The side wall of the threaded sleeve 9 is provided with four hinged rods 10 spaced apart along its circumference. The upper end of the hinged rod 10 is hinged to the side wall of the threaded sleeve 9, and the lower end of each hinged rod 10 is hinged to the top of each expansion plate 3. Since the support rod 2 is a threaded rod and is threadedly sleeved on its outside, when power is transmitted to the threaded sleeve 9, the threaded sleeve 9 moves up and down along the axial direction of the support rod 2. The four hinged rods 10 spaced apart along the circumference of the side wall of the threaded sleeve 9 extend and retract with the movement of the threaded sleeve 9, thereby pushing and pulling the expansion plate 3 to slide horizontally along the cross rib plate 101 of the cross stabilizing plate 1, realizing the outward expansion or inward contraction of the expansion plate 3.
[0020] Specifically, the drive mechanism includes a rotating sleeve 11 coaxially rotatably connected to the top of the support rod 2. Four sliding rods 12 are fixedly connected to the bottom of the rotating sleeve 11 and spaced apart along its circumference. The sliding rods 12 pass downward through the threaded sleeve 9 and are slidably connected to it. When the rotating sleeve 11 rotates, it will drive the sliding rods 12 to rotate synchronously, and then drive the threaded sleeve 9 to rotate together through the rotational driving force of the sliding rods 12. Since the threaded sleeve 9 is threadedly connected to the support rod 2, the threaded sleeve 9 will move axially upward or downward along the threaded trajectory on the support rod 2 during rotation. The axial movement of the threaded sleeve 9 will drive the extension and retraction of the hinge rod 10 hinged to its side wall, ultimately providing the power basis for the first transmission mechanism to drive the extension plate 3 to slide.
[0021] In a preferred embodiment of this utility model, the second transmission mechanism includes a transmission screw 13 coaxially fixedly connected to the top of the rotating sleeve 11. The lifting sleeve 4 has an internal thread, and the lifting sleeve 4 is threadedly connected to the transmission screw 13. When the rotating sleeve 11 is rotated, the transmission screw 13 rotates synchronously with the rotating sleeve 11. Since the lifting sleeve 4 has an internal thread and is threadedly connected to the transmission screw 13, and the top plate 5 is fixed at the top of the lifting sleeve 4, the top plate 5 is restricted from rotating by the template body. When the transmission screw 13 rotates, it will drive the lifting sleeve 4 to move upward along the axial direction of the transmission screw 13, thereby driving the top plate 5 and the template body to rise synchronously.
[0022] Specifically, the bottom end of the cross-rib plate 101 is provided with a sliding groove 14, and the extension plate 3 is horizontally slidably connected in the sliding groove 14. The outer end of the extension plate 3 is integrally formed with a fixing plate 15, and the fixing plate 15 has a positioning screw hole 16. When the extension plate 3 slides along the sliding groove 14 to the preset support position, the construction personnel can insert bolts or other fasteners through the positioning screw hole 16 through the fixing plate 15 to connect the fixing plate 15 to the ground, scaffolding or other fixed structure, thereby fixing the extension plate 3 in the current position and preventing it from sliding.
[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
