Description

Technical Field

[0001] This invention relates to the field of prefabricated composite slab construction technology, specifically to a prefabricated composite slab disc-lock quick-release support frame and its construction method. Background Technology

[0002] Currently, the commonly used prefabricated composite slab support frames in the industry include conventional fastener-type steel pipe support frames, ring-lock steel pipe support frames, disc-lock steel pipe support frames, and independent triangular support frames.

[0003] Currently available fastener-type and ring-lock type steel pipe support frames on the market are of poor quality, with severe wall thickness and corrosion. Their use has been restricted in some areas, and they cannot meet the actual needs of engineering projects.

[0004] Conventional disc-lock scaffolding can be flexibly combined with cast-in-place slab scaffolding. Currently, the quality of disc-lock scaffolding on the market is relatively good, meeting engineering and national requirements. However, the horizontal support rod module of disc-lock scaffolding is relatively simple, and it cannot achieve a support-free effect; it must be used in conjunction with a supporting joist. Currently, the commonly used main joists are timber and steel pipes. However, the quality of timber on the market varies, and steel pipes are severely rusted, with inconsistent wall thicknesses, making them prone to deformation. This results in uneven joints at the composite slab joints, serious grout leakage, and high costs for subsequent grinding and repair.

[0005] Independent triangular support frames are suitable for closely spaced composite slab support frames. However, when dealing with slab-strip composite slabs, independent triangular support frames cannot be combined with cast-in-place slab support frames and are no longer applicable.

[0006] To address the aforementioned deficiencies in composite slab support systems, we propose a prefabricated composite slab disc-lock quick-release support frame and its construction method. Summary of the Invention

[0007] The purpose of this invention is to provide a prefabricated composite plate disc-lock quick-release support frame to solve the defects of the support frame mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated composite slab disc-lock quick-release support frame, comprising: Multiple uprights, each upright having multiple connecting discs spaced at intervals along the vertical direction; Multiple crossbars, the two ends of which are detachably connected to the connecting plate via a connecting seat assembly; Multiple diagonal braces, the two ends of which are detachably connected to the connecting plate via connecting seat assemblies; An adjustable base is provided at the bottom of the upright and is used to adjust the bottom height of the upright. An adjustable top support is provided at the top of the upright and is used to adjust the top height of the upright. A square steel bar is installed on top of the adjustable top support; Plywood is placed on top of the square steel to support the assembled composite slab.

[0009] By adopting the above technical solution, through the disc-lock connection structure of uprights, horizontal bars, and diagonal braces, combined with the height adjustment function of adjustable bases and adjustable top supports, and the support structure of square steel and plywood, the problems of poor quality of existing fastener-type and ring-lock support frames, the single modularity of disc-lock support frames requiring the use of inferior keels, and the limited adaptability of independent triangular support frames are effectively solved. This achieves modular assembly of the frame structure and reduces material usage, flexibly adapting to both panel and closely spaced composite slab construction, ensuring a flat support surface for the composite slabs, reducing grout leakage at joints and subsequent grinding costs, while also meeting the requirements for quick disassembly and assembly, improving construction efficiency and project quality.

[0010] As a preferred embodiment of the present invention, the connecting seat assembly includes a snap-fit ​​connector and a pin. The snap-fit ​​connector is fixedly connected to the crossbar or diagonal brace, and the pin passes through the snap-fit ​​connector and the connecting plate to snap-fit ​​the snap-fit ​​connector onto the connecting plate.

[0011] The above technical solution employs a snap-fit ​​connector and pin-plate connection method, enabling quick and secure assembly / disassembly of horizontal bars, diagonal braces, and vertical poles. Compared to the cumbersome operation and risk of loosening associated with traditional fastener connections, installation simply involves snapping the snap-fit ​​connector into the connecting plate and inserting the pin-plate to lock it in place. Disassembly is achieved by reversing the operation for quick separation, significantly improving the efficiency of frame assembly and disassembly.

[0012] As a preferred embodiment of the present invention, the adjustable base includes a steel plate base, a first threaded rod, and a first nut. The lower end of the first threaded rod is connected to the steel plate base, the upper end of the first threaded rod extends into the upright, and the lower end of the upright is rotatably connected to the first nut. The first nut is threaded onto the first threaded rod to lock the relative position of the first threaded rod and the upright.

[0013] By adopting the above technical solution, the threaded adjustment structure of the steel plate base, the first threaded rod and the first nut can be flexibly adapted to different ground flatness. The height of the bottom of the upright can be precisely adjusted by rotating the first nut to ensure the verticality of the upright, thereby enhancing the stability of the bottom of the frame and the uniformity of load transfer. This avoids the problem of the frame tilting or local overload caused by uneven ground, and provides a reliable bottom support foundation for the entire support frame.

[0014] As a preferred embodiment of the present invention, the adjustable top support includes a channel steel, a second threaded rod, and a second nut. The upper end of the second threaded rod is connected to the channel steel, and the lower end of the second threaded rod extends into the upright. The upper end of the upright is rotatably connected to the second nut, and the second nut is threaded onto the second threaded rod to lock the relative position of the second threaded rod and the upright.

[0015] By adopting the above technical solution, the threaded adjustment structure of channel steel, second threaded rod and second nut can accurately adjust the height of the top support to adapt to the support requirements of composite slabs of different thicknesses. The channel steel, as the support carrier of the square steel, can ensure the flatness and uniformity of the square steel installation. The locking function of the second nut can stabilize and fix the position after the height is adjusted, avoiding the top support from loosening and settling during construction, and ensuring the flatness of the composite slab support surface and construction safety.

[0016] This invention also provides a construction method for a prefabricated composite slab disc-lock quick-release support frame, comprising the following steps: Step 1: Layout the uprights according to the specific construction plan and mark the positioning axis; Step 2: Determine the spacing of the uprights, horizontal bars, and diagonal braces, and adjust the bottom height of the uprights using adjustable bases to ensure the uprights are vertical; Step 3: Connect the horizontal bars and diagonal braces to the connecting plates on the uprights using connecting seat assemblies to assemble the main frame body; Step 4: Install adjustable top supports on the top of the uprights, adjust their height, install square steel, and lay plywood on the square steel; Step 5: Mark the composite slab positioning lines on the plywood, attach double-sided tape to the outside of the positioning lines, and install the concrete composite slab.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: Through the disc-lock connection structure of uprights, horizontal bars, and diagonal braces, combined with the height adjustment functions of adjustable bases and adjustable top supports, and the support structure of square steel and plywood, it effectively solves the problems of poor quality of existing fastener-type and ring-lock support frames, the single modularity of disc-lock support frames requiring the use of inferior keels, and the limited adaptability of independent triangular support frames. It achieves modular assembly of the frame body and reduces material usage, flexibly adapting to both strip-type and closely spaced composite slab construction, ensuring a flat support surface for the composite slabs, reducing grout leakage at joints and subsequent grinding costs, while also meeting the requirements for quick disassembly and assembly, improving construction efficiency and project quality.

Detailed Implementation

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

[0020] Please see Figure 1-4 The technical solution of the present invention is: a prefabricated composite plate disc buckle quick-release support frame, including multiple uprights 1, multiple horizontal bars 2, multiple diagonal braces 3, adjustable base 5, adjustable top support 6, square steel 7 and plywood 8.

[0021] The upright 1 is made of high-strength steel pipe, with multiple connecting discs 4 spaced apart along the vertical direction. The connecting disc 4 is a disc structure with multiple interfaces evenly opened around its circumference, which are used to connect with the connecting seat assembly 9 of the horizontal bar 2 and the diagonal brace 3 to ensure the load transfer of the upright 1 in the vertical direction and the overall stability of the frame.

[0022] Both the horizontal bar 2 and the diagonal brace 3 are made of steel pipes compatible with the vertical bar 1, and their ends are detachably connected to the connecting plate 4 via the connecting seat assembly 9. The connecting seat assembly 9 includes a snap-fit ​​connector 901 and a pin 902: the snap-fit ​​connector 901 is welded and fixed to the end of the horizontal bar 2 or the diagonal brace 3; the pin 902 can pass through the interface between the snap-fit ​​connector 901 and the connecting plate 4, snapping the snap-fit ​​connector 901 onto the connecting plate 4. This connection method enables quick assembly and disassembly of the horizontal bar 2, diagonal brace 3, and vertical bar 1, while ensuring a firm connection, forming a stable spatial truss structure and enhancing horizontal and diagonal stiffness.

[0023] An adjustable base 5 is located at the bottom of the upright 1 and consists of a steel plate base 501, a first threaded rod 502, and a first nut 503. The lower end of the first threaded rod 502 is welded to the steel plate base 501, and the upper end extends into the lower end cavity of the upright 1. The first nut 503 is rotatably connected to the lower end of the upright 1, and can be fitted with a bearing or a slot, with its threads threaded onto the first threaded rod 502. By rotating the first nut 503, the first threaded rod 502 can be driven to move vertically, thereby adjusting the bottom height of the upright 1 to adapt to different ground flatness, ensuring the upright 1 is vertical, and providing stable bottom support for the frame.

[0024] An adjustable top support 6 is located at the top of the upright 1 and consists of a channel steel 601, a second threaded rod 602, and a second nut 603. The upper end of the second threaded rod 602 is welded to the channel steel 601, and the lower end extends into the upper cavity of the upright 1. The second nut 603 is rotatably connected to the upper end of the upright 1 and is threaded onto the second threaded rod 602. Rotating the second nut 603 drives the second threaded rod 602 to move vertically, thereby adjusting the height of the channel steel 601 to match the support height requirements of the composite plate. The channel steel 601 supports the square steel 7, ensuring the flatness of the square steel 7 during installation.

[0025] Square steel 7 is laid on channel steel 601 of adjustable top support 6 and can be detachably connected to channel steel 601 by bolts to form the main support keel of the composite panel; plywood 8 is laid on square steel 7 and fixed to square steel 7 by nails or self-tapping screws, serving as the direct support panel of the composite panel. Its specifications match the panel type of the prefabricated composite panel to ensure the flatness of the support surface of the composite panel.

[0026] This invention also provides a construction method for a prefabricated composite slab disc-lock quick-release support frame, the specific steps of which are as follows: Step 1: Determine the arrangement spacing of the uprights 1, horizontal bars 2, and diagonal braces 3 according to the dimensions, load, and specific construction plan of the composite slab, and mark the positioning axis of the uprights 1 in the construction area to ensure accurate frame arrangement; Step 2: Place the steel plate base 501 of the adjustable base 5 on the ground, rotate the first nut 503 to adjust the bottom height of the uprights 1, keep the uprights 1 vertical, and complete the initial installation of the uprights 1; Step 3: Use the connecting seat assembly 9 to snap the snap-fit ​​connectors 901 of the horizontal bars 2 and diagonal braces 3 into the uprights 1. Connect the interface of the connecting plate 4, insert the pin 902 to complete the fixation, and assemble the horizontal bars 2 and diagonal braces 3 of each layer in sequence to form a stable frame body; Step 4: Install the adjustable top support 6 on the top of the upright 1, and rotate the second nut 603 to adjust the height of the channel steel 601 to the design value; Lay the square steel 7 on the channel steel 601 and fix it, and then lay the plywood board 8 on the square steel 7 to complete the construction of the top support surface; Step 5: Mark the positioning line of the composite plate on the plywood board 8, stick double-sided tape on the outside of the positioning line to seal the joint and prevent grout leakage, and then hoist the concrete composite plate onto the plywood board 8, align it with the positioning line to complete the installation.
