Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a composite slab support frame and its support system. Background Technology

[0002] With the increasing proportion of prefabricated buildings in housing construction projects, composite slabs, as a high-efficiency and energy-saving prefabricated component, have been widely used in floor slab installation. The construction process for composite slabs typically involves first installing supports, then hoisting and installing the composite slabs, and finally pouring the concrete for the post-cast strip. The support system plays a crucial supporting role in composite slab construction, directly affecting construction efficiency, safety, and cost. Existing composite slab construction methods often use formwork and full-span scaffolding, but this method requires the use of socket-type disc-lock scaffolding under the composite slab and at the post-cast strip. This results in a large scaffolding coverage area, which is time-consuming during subsequent installation and dismantling, delaying the construction schedule. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, which mainly uses full-span scaffolding for composite slab construction, resulting in long dismantling time and delays in construction progress. This utility model provides a composite slab support frame and its support system.

[0004] In a first aspect, the present invention provides a composite plate support frame, including a support platform for mounting composite plates, a plurality of legs vertically arranged below the support platform, adjacent two legs being connected by a diagonal bracing device, a telescopic structure below each leg, the telescopic structure being able to control the lifting and lowering of the support platform, and a pulley rotatably connected to one side of each leg.

[0005] This invention provides a composite slab support frame. A support platform is used to support the composite slab, which is supported by multiple legs. Adjacent legs are connected by diagonal bracing, strengthening the connection between legs and improving the lateral tensile strength of the entire frame. Each leg has a telescopic structure that allows the support platform to be raised and lowered, thus enabling the composite slab to be raised and lowered for easy installation. After construction, the support platform can be lowered using the telescopic structure for easy retrieval. Compared to traditional full-span scaffolding that requires dismantling after completion, this invention simplifies both the pre-construction preparation and post-construction handling processes, improving efficiency and accelerating the construction period. The legs also have pulleys, allowing the entire composite slab support frame to be moved easily.

[0006] Preferably, the support leg is a hollow structure, and a connecting plate is fixedly connected to the lower part of the support leg. The support leg is connected to the telescopic structure through the connecting plate, and the telescopic structure can move axially within the support leg through the connecting plate.

[0007] By designing the legs as hollow structures, the weight of the entire composite slab support frame is reduced on the one hand, and the telescopic structure can move axially inside the legs on the other hand. The legs are connected to the telescopic structure through connecting plates, which increases the contact area between the telescopic structure and the composite slab support frame, and at the same time improves the structural strength of the connection.

[0008] Preferably, the telescopic structure includes a lead screw;

[0009] The connecting plate has a vertically opening connecting hole, and the end of the lead screw facing the support platform is connected to the connecting plate through the connecting hole.

[0010] The lead screw and the connecting plate are connected through the connecting hole to achieve a reliable docking between the telescopic structure and the outrigger. The structure is simple and the connection is stable, which is conducive to the stable guidance and axial movement of the lead screw in the outrigger, and improves the operating accuracy and reliability of the telescopic structure.

[0011] Preferably, a pad is provided at the end of the lead screw away from the support platform, and the pad abuts against the lead screw;

[0012] A force-bearing component is fixedly connected to the middle of the lead screw, and the force-bearing component is located in the area below the connecting plate.

[0013] A pad is installed at one end of the lead screw, which can form an effective support and bearing surface during the lifting process, preventing the lead screw from directly contacting the ground and causing wear or damage, thus improving service life and stability. The force-bearing component is fixedly connected in the middle of the lead screw, which helps to effectively transfer external loads or support forces to the lead screw body, making the force evenly distributed during the lifting process and improving the overall structure's load-bearing capacity and operational reliability.

[0014] Preferably, the main body of the inclined cable device is a scissor brace.

[0015] Preferably, the support platform includes a mounting platform for mounting the composite plate, and the support platform further includes a side mold mounting platform, which is movably connected to the mounting platform.

[0016] Preferably, a hinge device is provided between the mounting platform and the side mold mounting platform. The hinge device includes a first leaf and a second leaf, which are connected by a pivot. The first leaf is connected to the side mold mounting platform, and the second leaf is connected to the mounting platform.

[0017] By incorporating a hinge mechanism, the side mold mounting platform can be flipped and folded. When not in use, it can be folded using the hinge mechanism, reducing the overall size of the support platform and facilitating subsequent transportation or storage.

[0018] Preferably, the side mold mounting platform and the support leg are connected by a diagonal brace, and the diagonal brace is detachably connected to the side mold mounting platform and the support leg.

[0019] By installing diagonal braces between the side plate mounting platform and the outriggers, the supporting force of the side plate mounting platform during use is improved, thus enhancing safety.

[0020] Preferably, the side of the side mold mounting platform connected to the diagonal brace is provided with a first mounting seat, and the side of the support leg connected to the diagonal brace is provided with a second mounting seat;

[0021] One end of the diagonal brace is detachably connected to the side mold mounting platform via the first mounting base, and the other end is detachably connected to the support leg via the second mounting base.

[0022] In a second aspect, the present invention provides a support system including the aforementioned composite plate support frame, wherein the support system is composed of only two of the aforementioned composite plate support frames.

[0023] This utility model provides a support system composed of at least two composite plate support frames. Since the composite plate support frames can be raised, lowered, and moved through telescopic structures and pulleys, and the entire support system is composed of at least two composite plate support frames, it is convenient to carry out batch construction of composite plates. After the construction is completed, multiple composite plate support frames can be transferred and recycled through telescopic structures and pulleys without the need for on-site disassembly, thus improving construction efficiency.

[0024] Preferably, a sealing plate is mounted between two adjacent composite plate support frames via the side mold mounting platform.

[0025] A sealing plate is constructed by installing platform supports on two adjacent side molds to seal the formwork joints during subsequent pouring.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. This utility model provides a composite slab support frame, which uses a support platform to support the composite slab. Multiple legs support the platform, providing structural support. Adjacent legs are connected by a diagonal bracing device, strengthening the connection between legs and improving the lateral tensile strength of the entire composite slab support frame. Each leg is equipped with a telescopic structure, allowing the support platform to be raised and lowered, thus enabling the composite slab to be raised and lowered for easy installation. After construction, the support platform can be lowered using the telescopic structure for easy retrieval. Compared to traditional full-span scaffolding that requires dismantling after completion, this utility model simplifies both the pre-construction preparation and post-construction handling processes, improving construction efficiency and accelerating the construction period. The legs are also equipped with pulleys, allowing the entire composite slab support frame to move easily.

[0028] 2. This utility model provides a support system, which is composed of at least two composite plate support frames. Since the composite plate support frame can be raised, lowered and moved through the telescopic structure and pulleys, and the entire support system is composed of at least two composite plate support frames, it is convenient to carry out batch construction of composite plates. After the construction is completed, multiple composite plate support frames can be transferred and recycled through the telescopic structure and pulleys without the need for on-site disassembly, thus improving construction efficiency.

Detailed Implementation

[0038] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0039] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0040] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0041] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0042] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0043] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0044] Example 1

[0045] like Figure 1 , Figure 2 and Figure 5 The composite plate support frame shown includes a support platform 1 for mounting the composite plate. Several legs 2 are vertically arranged below the support platform 1. The legs 2 have a hollow structure and a connecting plate 22 is fixedly connected to the lower part of the legs 2. The connecting plate 22 has a vertically opened connecting hole 221.

[0046] The connecting plate has a telescopic structure 4 on the side away from the outrigger. The telescopic structure 4 includes a lead screw 41, which is connected to the connecting plate 22 through a connecting hole 221 (one end of the lead screw 41 passes through the connecting plate 22 through the connecting hole 221 and moves within the cavity of the outrigger 2). The lead screw 41 also has a force-bearing component 43, which is fixedly connected to the lead screw 41. This allows the lead screw 41 to move by turning the force-bearing component 43 with other tools (wrench) during subsequent use. The end of the lead screw 41 that does not pass through the connecting hole 221 has a pad 42, which abuts against the lead screw 41, providing a bearing surface for the lead screw 41.

[0047] The support leg 2 is also equipped with a pulley 5. When the lead screw 41 moves to the point where it no longer contacts the pad 43, the entire composite plate support frame contacts the ground through the pulley 5, which facilitates the transfer of the composite plate support frame. When the lead screw 41 extends out of the support leg 2 and abuts against the pad 43, the lead screw 41 continues to rotate to drive the support leg 2 to rise. The pulley 5 rises along with the support leg 2. When it rises to a certain height, the pulley 5 no longer contacts the ground, thus preventing the entire composite plate support frame from deviating from its position during use.

[0048] Furthermore, two adjacent support legs 2 are connected by a diagonal bracing device 3, and the body of the diagonal bracing device 3 is a scissor brace. The installation of the diagonal bracing device 3 enhances the structural stability and shares the lateral load of the entire composite plate support frame.

[0049] In one or more embodiments, the support platform 1 includes a mounting platform 11 for mounting the composite plate, and the support platform 1 also includes a side mold mounting platform 12, which is movably connected to the mounting platform 11.

[0050] Furthermore, the side mold mounting platform 12 is connected to the mounting platform 11 via a hinge device 6. The side mold mounting platform 12 can be flipped using the hinge device 6. By setting the hinge device 6, the side mold mounting platform 12 can be flipped and folded. When not in use, it can be folded using the hinge device 6, reducing the size of the entire support platform 1 for easier subsequent transportation or storage. The hinge device 6 includes a first leaf 61 and a second leaf 62, which are connected by a pivot 63. The first leaf 61 is connected to the side mold mounting platform 12, and the second leaf 62 is connected to the mounting platform 11. Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown.

[0051] In this application, the support legs 2 are provided with at least 4, which improves the stability of the entire composite plate support frame.

[0052] In one or more embodiments, the side mold mounting platform 12 and the support leg 2 are connected by a diagonal brace 7, and the diagonal brace 7 is detachably connected to the side mold mounting platform 12 and the support leg 2.

[0053] Furthermore, the side of the side mold mounting platform 12 connected to the diagonal brace 7 is provided with a first mounting seat 121, and the side of the support leg 2 connected to the diagonal brace 7 is provided with a second mounting seat 21;

[0054] One end of the diagonal brace 7 is detachably connected to the side mold mounting platform 12 via the first mounting base 121, and the other end is detachably connected to the support leg 2 via the second mounting base 21. By setting the diagonal brace 7 between the side plate mounting platform and the support leg 2, the supporting force of the side plate mounting platform during use is improved, thus enhancing safety. Figure 1 , Figure 2 and Figure 3 As shown.

[0055] Example 2

[0056] like Figure 6 The support system shown includes a composite slab support frame as described in Embodiment 1. The support system is composed of only two composite slab support frames. A sealing plate 8 is mounted on a side formwork mounting platform 12 between two adjacent composite slab support frames. Since the composite slab support frame can be raised, lowered, and moved through the telescopic structure 4 and pulleys 5, the entire support system is composed of at least two composite slab support frames, which facilitates batch construction of composite slabs. After construction is completed, multiple composite slab support frames can be transferred and retrieved through the telescopic structure 4 and pulleys 5 without on-site disassembly, thus improving construction efficiency.

[0057] Example 3

[0058] This Example 3 describes the usage method of Example 2.

[0059] The construction site is surveyed and marked out to determine the installation position of each composite slab and the placement position of the composite slab support frame. Each composite slab support frame is moved to the placement position using pulleys 5, and a pad 42 is placed at the position to provide a bearing surface for the expansion joint 4. Then, the composite slab support frame is raised to the design height using the expansion joint 4. After that, sealing plates 8 are placed on the two adjacent side formwork installation platforms 12 to seal the formwork joints. After completion, construction (reinforcement binding and concrete pouring) begins. When the concrete strength reaches the demolding conditions, the composite slab support frame is recycled.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
