Description

Technical Field

[0001] This invention relates to the field of civil engineering construction technology, and in particular to a scaffolding suspension support structure and a support system for horizontal beams, inclined beams, drop slabs, and closely spaced beams. Background Technology

[0002] In building construction, formwork support for floor slabs and beams is a crucial step in ensuring the quality of structural completion. Traditional support methods often employ full-span scaffolding to independently support floor slabs and beams, which has the following drawbacks:

[0003] Large space occupation: Due to the limitations of the length and spacing of the uprights, additional independent uprights need to be installed under the crossbeams, resulting in narrow construction space and affecting material transportation and personnel operation.

[0004] Poor adjustment flexibility: It is impossible to dynamically adjust the support position according to parameters such as beam height and tilt angle, and the scaffolding often needs to be disassembled and reassembled frequently.

[0005] Uneven load distribution: Single vertical support can easily lead to local stress concentration in the beam, especially in irregular structures such as inclined beams and dropped slabs, where traditional support systems can hardly achieve balanced force transmission.

[0006] Low construction efficiency: The erection and dismantling of multiple independent support systems is time-consuming and labor-intensive, and additional steel pipes are required to ensure overall stability.

[0007] To address the aforementioned problems, this invention provides an integrated and adjustable scaffolding suspension support structure. Through modular design and multi-dimensional adjustment functions, it achieves efficient and stable support for floor slabs and various beam structures. Summary of the Invention

[0008] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a scaffolding suspension support structure and a support system of horizontal beams, inclined beams, drop slabs and dense beams, to solve the problems of low space utilization, poor adjustment flexibility, uneven load distribution and low use efficiency of the existing scaffolding structure when it is used for irregular floor slab structures.

[0009] To address the aforementioned technical problems, this invention provides a scaffolding suspension support structure for simultaneously supporting both the floor slab and the beam structure installed on the floor slab, comprising:

[0010] The upper support keel and the lower support keel each include two parallel horizontal sleeves. The top surface and bottom surface of the horizontal sleeves are respectively provided with a top groove and a bottom groove, which are arranged along the extension direction of the horizontal sleeves.

[0011] A tension adjusting component includes a bidirectional adjusting screw, an upper chuck disposed on the upper part of the bidirectional adjusting screw, and a lower chuck disposed on the lower part of the bidirectional adjusting screw. The threads of the upper and lower parts of the bidirectional adjusting screw have opposite directions. The upper and lower chucks are threadedly connected to the bidirectional adjusting screw. The upper chuck is provided with two upper sliding protrusions adapted to the top groove, and the lower chuck is provided with two lower sliding protrusions adapted to the bottom groove.

[0012] The upper support keel is located below the floor slab and fixed with uprights to support the floor slab. The lower support keel, located below the beam structure, is suspended below the beam structure by the tension adjustment member to support the beam structure. The upper sliding protrusion of the upper chuck is respectively engaged in the two top grooves of the upper support keel, and the lower sliding protrusion of the lower chuck is respectively engaged in the two bottom grooves of the lower support keel. The bidirectional adjustment screw is located between two horizontal sleeves. Tightening the bidirectional adjustment screw causes the upper and lower chucks to move in opposite directions, thereby adjusting the distance between the lower support keel and the beam structure. At the same time, the upper and lower chucks slide along the extension direction of the horizontal sleeves to adjust the load distribution on the lower support keel.

[0013] As a preferred embodiment, the bidirectional adjusting screw is equipped with a rotating handle in the middle for easy rotation. This design allows the screw to be rotated without additional tools, significantly reducing the difficulty of spacing adjustment and improving construction efficiency. The rotating handle also allows the operator to directly grip and apply force, preventing slippage due to the screw's smooth surface. Furthermore, it enables more precise control of the adjustment range, ensuring the spacing between the lower support keel and the crossbeam is properly adjusted, thus enhancing operational convenience.

[0014] As a preferred method, multiple upper support keels are extended together using keel connectors. Each keel connector includes a square tube adapted to the outer contour of the upper support keel and a double-arm pin at the end of the square tube. The double-arm pin includes two connecting arms adapted to a horizontal sleeve. The connecting arms at both ends of the keel connector are inserted into one end of two adjacent upper support keels, connecting them. The advantages are that the square tube of the keel connector adapts to the outer contour of the upper support keel, and the double-arm pin can be directly inserted into the horizontal sleeve to extend multiple keels. The connection method is simple and efficient, requiring no welding or complex bolt fixing, thus shortening construction time. Simultaneously, the cooperation between the square tube and the double-arm pin ensures the straightness of the extended keel, avoiding uneven support stress caused by connection deviations and improving the overall structural stability of the upper support keel.

[0015] To address the aforementioned problems, the present invention also provides a beam support system for simultaneously supporting a floor slab and beams disposed on the floor slab, comprising:

[0016] Several of the above-mentioned scaffolding suspension support structures;

[0017] The scaffolding structure is a frame structure built of multiple uprights and horizontal bars. The uprights pass through the gap between the two horizontal sleeves of the lower support joists and are connected to the upper support joists. The upper support joists are erected on the uprights to support the floor slab. The lower support joists are located below the horizontal beams and are connected to the upper support joists at both ends through the tension adjustment members and are suspended from the lower side of the upper support joists.

[0018] As a preferred embodiment, the beam support system further includes a U-shaped clamp, which comprises two limiting pins connected at one end. The horizontal sleeve has two through-holes in its radial direction. Inserting the limiting pins into the corresponding limiting holes simultaneously limits the upright within the two pins. The advantage is that after the limiting pins of the U-shaped clamp are inserted into the limiting holes of the horizontal sleeve, the upright can be firmly fixed between the two pins, effectively preventing displacement of the scaffold upright due to vibration or load changes, and avoiding support failure caused by upright misalignment. The clamp installation requires no additional drilling or welding, is simple and quick to operate, and can quickly fix the relative position of the upright and the keel, strengthening the connection stability between the scaffold and the suspended support structure.

[0019] To better address the aforementioned problems, the present invention also provides a inclined beam support system for simultaneously supporting a floor slab and an inclined beam disposed on the floor slab, comprising:

[0020] Several of the above-mentioned scaffolding suspension support structures;

[0021] The scaffolding structure is a frame structure built of multiple uprights and horizontal bars. The uprights pass through the gap between the two horizontal sleeves of the lower support keel and are connected to the upper support keel. The upper support keel is erected on the uprights to support the floor slab. The lower support keel is set below the inclined beam and is connected to the upper support keel at both ends through the tension adjustment members and is suspended from the lower side of the upper support keel.

[0022] The scaffolding suspension support structure further includes two pressure-bearing adjustment components, which are respectively disposed on both sides of the inclined beam. The two ends of the lower support keel bear the upward tension applied by the tension adjustment component, and the middle part of the lower support keel bears the downward pressure applied by the pressure-bearing adjustment component. The upward tension and the downward pressure are balanced.

[0023] As a more preferred embodiment, the pressure-bearing adjustment component includes two sets of paired upper and lower chucks. One set of upper and lower chucks is located on the upper part of the bidirectional adjusting screw and respectively engages with the top and bottom grooves of the upper support keel. The other set of upper and lower chucks is located on the lower part of the bidirectional adjusting screw and respectively engages with the top and bottom grooves of the lower support keel. By rotating the pressure-bearing adjustment component, the gap between the upper and lower support keels is reduced, and the upper chuck at the lower part of the bidirectional adjusting screw applies a downward pressure to the lower support keel. The beneficial effect is that the pressure-bearing adjustment component, through the two pairs of upper and lower chucks respectively engaging with the top and bottom grooves of the upper and lower support keels, ensures a stable pressure transmission path and avoids pressure concentration that could lead to keel deformation. Tightening the bidirectional adjusting screw can reduce the keel spacing and apply downward pressure. The adjustment is highly accurate and can be flexibly adjusted according to the actual load of the inclined beam to ensure the force balance of the lower support keel. At the same time, the cooperation between the chuck and the groove makes the pressure adjustment part less likely to fall off, thus improving structural safety.

[0024] As a preferred method, the uprights of the scaffolding structure are distributed in an array with uniform spacing. The advantage of this is that, unlike existing technologies, which require additional independent uprights at the bottom of inclined beams and whose spacing is often not modular, necessitating additional steel pipe connections, this method saves on upright material and connecting pipe costs, and avoids disrupting the modular layout of the scaffolding due to independent uprights. Uniform spacing makes upright erection more standardized, increases construction efficiency, reduces on-site adjustments, and lowers construction complexity.

[0025] To address the aforementioned problems, the present invention also provides a slab support system for simultaneously supporting the floor slab and the slab structure, comprising:

[0026] Several of the above-mentioned scaffolding suspension support structures;

[0027] The scaffolding structure is a frame structure built from multiple uprights and horizontal bars. The upper support joists are erected on the uprights to support the floor slab. The lower support joists are set below the lower slab. The uprights pass through the gap between the two horizontal sleeves of the lower support joists and are connected to the upper support joists. One end of the lower support joists is connected to the upper support joists through the tension adjustment member and is suspended under the upper support joists, while the other end is erected on the uprights.

[0028] To address the aforementioned problems, the present invention also provides a gutter support system for simultaneously supporting both the floor slab and the gutter structure, comprising:

[0029] Several of the above-mentioned scaffolding suspension support structures;

[0030] The scaffolding structure is a frame structure built from multiple uprights and horizontal bars. The uprights pass through the gap between the two horizontal sleeves of the lower support joists and are connected to the upper support joists. The upper support joists are erected on the uprights to support the floor slab. The lower support joists are located below the gutter structure and are connected to the upper support joists at both ends through the tension adjustment members and are suspended from the lower side of the upper support joists.

[0031] Its advantages lie in the fact that gutter structures are typically located at the edge of buildings with limited construction space below. The lower support joists are suspended from the upper support joists at both ends via tension adjustment components, eliminating the need for vertical supports under the gutter. Furthermore, the existing support capacity of the upper support joists is utilized, eliminating the need for additional support points. The suspension design allows for flexible adjustment of the distance between the gutter and the lower support joists, preventing deformation of the gutter due to improper support and ensuring the quality of gutter construction.

[0032] To address the aforementioned problems, the present invention also provides a close-beam support system for simultaneously supporting both the floor slab and the close-beam structure, comprising:

[0033] Several of the above-mentioned scaffolding suspension support structures;

[0034] The scaffolding structure is a frame structure built from multiple uprights and horizontal bars. The lower support joists are erected on the uprights to support multiple closely spaced beams. The upper support joists are set under the floor slab between the closely spaced beams and are connected to the lower support joists at both ends through the tension adjustment members and are set on the upper side of the lower support joists.

[0035] As a more preferred embodiment, the close-beam support system further includes a top support assembly. The top support assembly includes a bidirectional adjusting screw, a slide rail anchoring component located at the lower part of the bidirectional adjusting screw, and a tray located at the upper part of the bidirectional adjusting screw. The slide rail anchoring component is equipped with a fixing foot, which is fixed to the top groove of the lower support keel. The tray abuts against the bottom of the upper support keel and supports the upper support keel. Its advantages are that the slide rail anchoring component of the top support assembly is fixed to the top groove of the lower support keel by the fixing foot, ensuring stable top support position; the bidirectional adjusting screw can flexibly adjust the height of the tray, allowing the tray to tightly abut against the bottom of the upper support keel, compensating for any small gaps that may occur in the upper support keel due to suspension, and preventing swaying of the upper support keel under stress. The top support assembly can help distribute the load on the upper support keel, and is particularly suitable for areas of concentrated stress in close-beam gap floor slabs, improving the support strength and stability of the upper support keel.

[0036] As described above, the scaffolding suspension support structure and the crossbeam, inclined beam, drop plate, and close beam support system of the present invention have the following beneficial effects:

[0037] The scaffolding suspension support structure of this invention achieves integrated support for the floor slab and beam structure through the horizontal sleeves and top and bottom grooves of the upper and lower support keels, combined with the bidirectional adjusting screws and upper and lower chucks of the tension adjustment components. This eliminates the need for two separate support systems, saving materials and construction space. The reverse thread design of the bidirectional adjusting screws allows for quick adjustment of the distance between the lower support keel and the beam by turning, adapting to different beam height requirements. The cooperation between the upper and lower sliding protrusions and the grooves allows for flexible adjustment of the chuck position along the extension direction of the keel, optimizing the load distribution of the lower support keel and avoiding local overload. At the same time, the upper support keel is fixed by uprights to ensure the stability of the floor slab support. The overall structure balances flexibility and reliability.

[0038] The beam support system of this invention integrates a scaffolding structure with a suspended support structure. The uprights pass through the horizontal sleeve gaps of the lower support joists and connect to the upper support joists, avoiding interference between the uprights and the lower support joists while simultaneously supporting both the floor slab and the beams. This eliminates the need for separate scaffolding for the beams, saving on material costs for uprights and horizontal members. Furthermore, the compact structure is suitable for confined construction spaces. The upper support joists, erected on the uprights, ensure the floor slab support strength, while the lower support joists suspend and support the beams, resulting in a clear force path and improved overall system load-bearing capacity.

[0039] The inclined beam support system of this invention addresses the issue of lateral forces easily generated by the special force direction of inclined beams. Through the cooperation of the compression adjustment components on both sides and the tension adjustment components at both ends, the lower support keel achieves a balanced force state of "tension at both ends and compression in the middle," preventing local bending or overload of the lower support keel due to the lateral force of the inclined beam. Simultaneously, it provides synchronous support for the floor slab and the inclined beam, eliminating the need for a separate inclined support structure for the inclined beam, simplifying the construction process, and adapting to the special support requirements of inclined beams.

[0040] The slab support system of this invention addresses the support needs of slab structures (where the floor slab is partially lowered). One end of the lower support joist is suspended by a tension adjustment component, allowing for flexible height adjustment to accommodate the drop in floor height. The other end is supported on uprights to ensure stability. This eliminates the need for a separate height-adjustable upright assembly for the slab, simplifying the height adaptation structure. Simultaneously, it achieves synchronous support for the floor slab and the slab, preventing support discontinuities caused by height differences and improving structural flatness during slab construction.

[0041] The dense beam support system of this invention addresses the characteristics of dense beam structures (beams arranged in close proximity with narrow gaps). The lower support joists are erected on uprights to support multiple dense beams as a whole, eliminating the need for individual support points for each beam and improving support efficiency. The upper support joists are positioned below the floor slab between the dense beams and suspended from the lower support joists via tension adjustment components. This avoids the upper support joists occupying space in the gaps between the dense beams. Existing technologies often result in difficulties in erecting floor slab supports or the need for excessive uprights due to narrow gaps. This system achieves simultaneous support of the "dense beams and floor slabs," adapting to the dense layout requirements of dense beam structures.

[0042] The scaffolding suspension support structure and the crossbeam, inclined beam, drop slab, and close beam support system of the present invention directly utilize the pre-fixed keel structure to suspend and support the irregular floor slab support keel, which greatly reduces the procedures required to support the irregular floor slab structure. It solves the problems of low space utilization, poor adjustment flexibility, uneven load distribution, and low efficiency of existing scaffolding structures for irregular floor slab structures.

[0065] like Figure 1 , Figure 2 as well as Figure 3 As shown, the present invention provides a scaffolding suspension support structure for simultaneously supporting a floor slab and a beam 8 structure installed on the floor slab, comprising:

[0066] The upper support keel 1 and the lower support keel 2 each include two parallel horizontal sleeves 3. The top surface and bottom surface of the horizontal sleeves 3 are respectively provided with a top groove 31 and a bottom groove 32. The top groove 31 and the bottom groove 32 are arranged along the extension direction of the horizontal sleeves 3.

[0067] The tension adjusting component 4 includes a bidirectional adjusting screw 41, an upper chuck 42 disposed on the upper part of the bidirectional adjusting screw 41, and a lower chuck 43 disposed on the lower part of the bidirectional adjusting screw 41. The threads of the upper and lower parts of the bidirectional adjusting screw 41 have opposite directions. The upper chuck 42 and the lower chuck 43 are threadedly connected to the bidirectional adjusting screw 41. The upper chuck 42 is provided with two upper sliding protrusions 421 that are adapted to the top groove 31, and the lower chuck 43 is provided with two lower sliding protrusions 431 that are adapted to the bottom groove 32.

[0068] The upper support keel 1 is located below the floor slab and fixed by the uprights 7 to support the floor slab. The lower support keel 2, located below the beam 8 structure, is suspended below the beam 8 structure by the tension adjustment member 4 to support the beam 8 structure. The upper sliding protrusion 421 of the upper chuck 42 is respectively engaged in the two top grooves 31 of the upper support keel 1, and the lower sliding protrusion 431 of the lower chuck 43 is respectively engaged in the two bottom grooves 32 of the lower support keel 2. The bidirectional adjustment screw 41 is located between the two horizontal sleeves 3. Tightening the bidirectional adjustment screw 41 causes the upper chuck 42 and the lower chuck 43 to move towards or away from each other, thereby adjusting the distance between the lower support keel 2 and the beam 8 structure. At the same time, the upper chuck 42 and the lower chuck 43 slide along the extension direction of the horizontal sleeves 3 to adjust the load distribution on the lower support keel 2.

[0069] The scaffolding suspension support structure of this invention, through the horizontal sleeves 3 of the upper and lower support keels 2 and the design of the top groove 31 and bottom groove 32, combined with the bidirectional adjusting screw 41 and the upper and lower chucks 43 of the tension adjustment component 4, achieves integrated support for the floor slab and beam 8 structure, eliminating the need to build two separate support systems, thus saving materials and construction space. The reverse thread design of the bidirectional adjusting screw 41 allows for quick adjustment of the distance between the lower support keel 2 and the beam 8 by screwing, adapting to different beam 8 height requirements; the cooperation of the upper and lower sliding protrusions 431 and the groove allows for flexible adjustment of the chuck position along the extension direction of the keel, optimizing the load distribution of the lower support keel 2 and avoiding local overload. At the same time, the upper support keel 1 is fixed by the uprights 7, ensuring the stability of the floor slab support. The overall structure balances flexibility and reliability.

[0070] In some possible embodiments of the present invention, such as Figure 1 , Figure 2 as well as Figure 3 As shown, a rotating handle 411 is provided in the middle of the bidirectional adjusting screw 41 for easy rotation. Its advantage lies in the fact that the rotating handle 411 in the middle of the bidirectional adjusting screw 41 allows rotation of the screw without additional tools, significantly reducing the difficulty of spacing adjustment and improving construction efficiency. The rotating handle 411 allows the operator to directly grip and apply force, avoiding slippage caused by the smoothness of the screw, while also enabling more precise control of the adjustment range, ensuring that the spacing between the lower support keel 2 and the crossbeam 8 is adjusted correctly, enhancing operational convenience.

[0071] In some possible embodiments of the present invention, such as Figure 16As shown, multiple upper support keels 1 are extended together by keel connectors 5. Each keel connector 5 includes a square tube 51 adapted to the outer contour of the upper support keel 1 and a double-arm pin 52 located at the end of the square tube 51. Each double-arm pin 52 includes two connecting arms 521 adapted to the horizontal sleeve 3. The connecting arms 521 at both ends of the keel connector 5 are inserted into one end of two adjacent upper support keels 1, connecting the two upper support keels 1. The advantages are that the square tube 51 of the keel connector 5 adapts to the outer contour of the upper support keel 1, and the double-arm pin 52 can be directly inserted into the horizontal sleeve 3 to extend multiple keels. The connection method is simple and efficient, requiring no welding or complex bolt fixing, thus shortening construction time. Simultaneously, the cooperation between the square tube 51 and the double-arm pin 52 ensures the straightness of the extended keel, avoiding uneven support stress caused by connection deviations, and improving the overall structural stability of the upper support keel 1.

[0072] To solve the above problems, such as Figure 4 As shown, the present invention also provides a beam support system for simultaneously supporting a floor slab and a beam 8 disposed on the floor slab, comprising:

[0073] Several of the above-mentioned scaffolding suspension support structures;

[0074] The scaffolding structure is a frame structure built from multiple uprights 7 and horizontal bars. The uprights 7 pass through the gap between the two horizontal sleeves 3 of the lower support keel 2 and are connected to the upper support keel 1. The upper support keel 1 is erected on the uprights 7 to support the floor slab. The lower support keel 2 is set below the horizontal beam 8 and is connected to the upper support keel 1 at both ends through the tension adjustment members 4 and is suspended from the lower side of the upper support keel 1.

[0075] The beam support system of this invention integrates a scaffolding structure with a suspended support structure. The uprights 7 pass through the gaps in the horizontal sleeves 3 of the lower support joists 2 and connect to the upper support joists 1. This avoids interference between the uprights 7 and the lower support joists 2, while simultaneously supporting both the floor slab and the beams 8. It eliminates the need for separate scaffolding for the beams 8, saving on material costs for the uprights 7 and horizontal members. Furthermore, the compact structure is suitable for confined construction spaces. The upper support joists 1, erected on the uprights 7, ensure the floor slab support strength, while the lower support joists 2 suspend and support the beams 8. The force path is clear, enhancing the overall load-bearing capacity of the system.

[0076] Existing beam support systems, such as Figure 5 As shown, the use of double-channel steel support beam 15, short uprights 13 and end crossbeams 8 has increased, and construction has become more difficult, greatly increasing labor and material costs.

[0077] In some possible embodiments of the present invention, such as Figure 4As shown, the beam support system also includes a U-shaped clamp 6, which includes two limiting pins connected at one end. The horizontal sleeve 3 has two through-holes in its radial direction. Inserting the limiting pins into the corresponding limiting holes simultaneously limits the upright 7 within the two limiting pins. The beneficial effect is that after the limiting pins of the U-shaped clamp 6 are inserted into the limiting holes of the horizontal sleeve 3, the upright 7 can be firmly fixed between the two pins, effectively preventing the scaffold upright 7 from shifting due to vibration or load changes, and avoiding support failure caused by the offset of the upright 7. The clamp installation requires no additional drilling or welding, is simple and quick to operate, and can quickly fix the relative position of the upright 7 and the keel, strengthening the connection stability between the scaffold and the suspended support structure.

[0078] To better solve the above problems, such as Figure 6 , Figure 7 as well as Figure 8 As shown, the present invention also provides a inclined beam support system for simultaneously supporting a floor slab and an inclined beam 9 disposed on the floor slab, comprising:

[0079] Several of the above-mentioned scaffolding suspension support structures;

[0080] The scaffolding structure is a frame structure built by multiple uprights 7 and horizontal bars. The uprights 7 pass through the gap between the two horizontal sleeves 3 of the lower support keel 2 and are connected to the upper support keel 1. The upper support keel 1 is erected on the uprights 7 to support the floor slab. The lower support keel 2 is set below the inclined beam 9 and is connected to the upper support keel 1 at both ends through the tension adjustment member 4 and is suspended on the lower side of the upper support keel 1.

[0081] The scaffolding suspension support structure further includes two pressure-bearing adjustment components 16, which are respectively disposed on both sides of the inclined beam 9. The two ends of the lower support keel 2 bear the upward tension applied by the tension adjustment component 4, and the middle part of the lower support keel 2 bears the downward pressure applied by the pressure-bearing adjustment component 16. The upward tension and the downward pressure are balanced.

[0082] The inclined beam support system of this invention addresses the issue of lateral force easily generated in the inclined beam 9 due to its special force direction. Through the cooperation of the compression adjustment components 16 on both sides and the tension adjustment components 4 at both ends, the lower support keel 2 achieves a balanced force state of "tension at both ends and compression in the middle," preventing local bending or overload of the lower support keel 2 caused by the lateral force of the inclined beam 9. Simultaneously, it provides synchronous support for the floor slab and the inclined beam 9, eliminating the need for a separate inclined support structure for the inclined beam 9, simplifying the construction process, and adapting to the special support requirements of the inclined beam 9.

[0083] Existing inclined beam support systems, such as Figure 9As shown, the addition of uprights 7 and crossbars along the extension direction of the inclined beam 9 greatly increases the construction difficulty and raises the cost of manpower and materials.

[0084] In some possible embodiments of the present invention, such as Figure 6 , Figure 7 as well as Figure 8 As shown, the pressure-adjusting component 16 includes two sets of paired upper chucks 42 and lower chucks 43. One set of upper chucks 42 and lower chucks 43 is located on the upper part of the bidirectional adjusting screw 41 and is respectively engaged with the top groove 31 and bottom groove 32 of the upper support keel 1. The other set of upper chucks 42 and lower chucks 43 is located on the lower part of the bidirectional adjusting screw 41 and is respectively engaged with the top groove 31 and bottom groove 32 of the lower support keel 2. By rotating the pressure-adjusting component 16, the gap between the upper support keel 1 and the lower support keel 2 is reduced, and the upper chuck 42 at the lower part of the bidirectional adjusting screw 41 applies a downward pressure to the lower support keel 2. The beneficial effect is that the pressure-adjusting component 16, through the two pairs of upper and lower chucks 43 respectively engaged with the top groove 31 and bottom groove 32 of the upper and lower support keels 2, ensures a stable pressure transmission path and avoids pressure concentration that could lead to keel deformation. Tightening the bidirectional adjusting screw 41 can reduce the keel spacing and apply downward pressure. The adjustment is highly accurate and can flexibly adjust the pressure according to the actual load of the inclined beam 9, ensuring the force balance of the lower support keel 2. At the same time, the cooperation between the chuck and the groove makes the pressure adjustment component 16 less likely to fall off, improving structural safety.

[0085] In some possible embodiments of the present invention, such as Figure 6 , Figure 7 as well as Figure 8 As shown, the uprights 7 of the scaffolding structure are distributed in an array with the same spacing. The advantage of this is that, by using an array with the uprights 7 at the same spacing, there is no need to install additional independent uprights 7 at the bottom of the inclined beams 9 as in existing technologies. Furthermore, the spacing of independent uprights 7 is often not modular, requiring additional steel pipe connections. This saves on the cost of upright materials and connecting steel pipes, and avoids disrupting the modular layout of the scaffolding due to independent uprights 7. The uniform spacing makes the erection of uprights 7 more standardized, increases construction efficiency, reduces on-site adjustments, and lowers construction complexity.

[0086] To solve the above problems, such as Figure 10 As shown, the present invention also provides a slab support system for simultaneously supporting the floor slab and the slab 10 structure, comprising:

[0087] Several of the above-mentioned scaffolding suspension support structures;

[0088] The scaffolding structure is a frame structure built from multiple uprights 7 and horizontal bars. The upper support joists 1 are erected on the uprights 7 to support the floor slab. The lower support joists 2 are set below the lower slab 10. The uprights 7 pass through the gap between the two horizontal sleeves 3 of the lower support joists 2 and are connected to the upper support joists 1. One end of the lower support joists 2 is connected to the upper support joists 1 through the tension adjusting member 4 and is suspended under the upper support joists 1. The other end is erected on the uprights 7.

[0089] The slab support system of this invention addresses the support requirements of the slab 10 structure (where the floor slab height is partially reduced). One end of the lower support keel 2 is suspended by a tension adjustment member 4, allowing for flexible height adjustment to accommodate the drop in slab 10. The other end is supported on the upright 7 to ensure support stability. This eliminates the need for a separate adjustable upright 7 assembly for slab 10, simplifying the height adaptation structure. Simultaneously, it achieves synchronous support for the floor slab and slab 10, preventing support discontinuity caused by the height difference in slab 10 and improving the structural flatness during slab 10 construction.

[0090] Existing drop plate support systems, such as Figure 11 As shown, the amount of upright poles 7 and short horizontal bars 14 has increased, and the construction process has also been expanded, increasing the cost of labor and materials.

[0091] To solve the above problems, such as Figure 12 As shown, the present invention also provides a gutter support system for simultaneously supporting the floor slab and the gutter 11 structure, comprising:

[0092] Several of the above-mentioned scaffolding suspension support structures;

[0093] The scaffolding structure is a frame structure built from multiple uprights 7 and horizontal bars. The uprights 7 pass through the gap between the two horizontal sleeves 3 of the lower support keel 2 and are connected to the upper support keel 1. The upper support keel 1 is erected on the uprights 7 to support the floor slab. The lower support keel 2 is set below the gutter 11 structure and is connected to the upper support keel 1 at both ends through the tension adjustment members 4 and is suspended from the lower side of the upper support keel 1.

[0094] The beneficial effects of the gutter support system of the present invention are as follows: the gutter 11 structure is usually located at the edge of the building, with limited construction space below. The lower support keel 2 is suspended from the upper support keel 1 at both ends by tension adjustment members 4, eliminating the need to install uprights 7 below the gutter 11 (saving edge space). Furthermore, it utilizes the existing support force of the upper support keel 1, eliminating the need for additional support points. The suspension design allows for flexible adjustment of the distance between the gutter 11 and the lower support keel 2, preventing deformation of the gutter 11 due to improper support and ensuring the construction quality of the gutter 11.

[0095] Existing gutter support systems, such as Figure 13 As shown, the use of short uprights 13 and short horizontal bars 14 has increased, raising the cost of manpower and materials.

[0096] To solve the above problems, such as Figure 14 As shown, the present invention also provides a close beam support system for simultaneously supporting the floor slab and the close beam 12 structure, comprising:

[0097] Several of the above-mentioned scaffolding suspension support structures;

[0098] The scaffolding structure is a frame structure built from multiple uprights 7 and horizontal bars. The lower support keel 2 is erected on the uprights 7 to support the multiple dense beams 12. The upper support keel 1 is set under the floor slab between the dense beams 12 and is connected to the lower support keel 2 at both ends through the tension adjustment member 4 and is set on the upper side of the lower support keel 2.

[0099] The dense beam support system of the present invention addresses the characteristics of the dense beam 12 structure (densely arranged beams with narrow gaps). The lower support joists 2 are erected on the uprights 7 to provide overall support for multiple dense beams 12, eliminating the need for individual support points for each beam 12 and improving support efficiency. The upper support joists 1 are positioned below the floor slab between the dense beams 12 and are suspended from the lower support joists 2 by tension adjustment components 4. This avoids the upper support joists 1 occupying space between the dense beams 12, as existing technologies often suffer from difficulties in erecting floor slab supports or require excessive uprights 7 due to the narrow gaps. This invention achieves synchronous support for "12-beam-floor slab" and adapts to the dense layout requirements of the 12-beam structure. It can be seen that the scaffolding suspension support structure and the crossbeam, diagonal beam, drop slab, and dense beam support system of the present invention directly utilize the pre-fixed keel structure to suspend and support the irregular floor slab support keel, which greatly reduces the procedures required to support the irregular floor slab structure and solves the problems of low space utilization, poor adjustment flexibility, uneven load distribution, and low efficiency of existing scaffolding structures for irregular floor slab structures.

[0100] Existing close-beam support systems, such as Figure 15 As shown, the use of short horizontal bars 14 and short vertical bars 13 has increased the cost of manpower and materials.

[0101] In some possible embodiments of the present invention, such as Figure 14As shown, the close beam support system also includes a top support assembly 17. The top support assembly 17 includes a bidirectional adjusting screw 41, a slide rail anchoring component located at the lower part of the bidirectional adjusting screw 41, and a tray located at the upper part of the bidirectional adjusting screw 41. The slide rail anchoring component is equipped with a fixing foot, which is fixed to the top groove 31 of the lower support keel 2. The tray abuts against the bottom of the upper support keel 1 and supports the upper support keel 1. Its advantages are that the slide rail anchoring component of the top support assembly 17 is fixed to the top groove 31 of the lower support keel 2 via the fixing foot, ensuring a stable top support position; the bidirectional adjusting screw 41 can flexibly adjust the height of the tray, allowing the tray to tightly abut against the bottom of the upper support keel 1, compensating for any small gaps that may occur in the upper support keel 1 due to suspension, and preventing the upper support keel 1 from swaying under load. The top support assembly 17 can help distribute the load of the upper support keel 1, and is particularly suitable for areas of concentrated local stress in the floor slab between close beams 12, improving the support strength and stability of the upper support keel 1.

[0102] As described above, the scaffolding suspension support structure and the crossbeam, inclined beam, drop plate, and close beam support system of the present invention have the following beneficial effects:

[0103] 1. Integrated support design

[0104] By using the horizontal sleeves 3 of the upper and lower supporting keel 2 and the design of the top groove 31 and bottom groove 32, and in conjunction with the bidirectional adjusting screw 41 and the upper and lower chucks 43 of the tension adjusting component 4, the integrated support of the floor slab and the beam 8 structure is realized, eliminating the need to build two separate support systems and saving materials and construction space.

[0105] 2. Quickly adjust spacing

[0106] The reverse thread design of the bidirectional adjusting screw 41 allows for quick adjustment of the distance between the lower support keel 2 and the crossbeam 8 by screwing, adapting to different crossbeam 8 height requirements and improving construction efficiency.

[0107] 3. Flexible adjustment of load distribution

[0108] The sliding protrusion 431 and the groove can flexibly adjust the position of the chuck along the extension direction of the keel, optimize the load distribution of the lower support keel 2, avoid local overload, and improve structural stability.

[0109] 4. Easy-to-use rotary handle 411

[0110] The rotating handle 411 in the middle of the bidirectional adjusting screw 41 allows the screw to be turned without additional tools, significantly reducing the difficulty of adjusting the spacing and improving construction efficiency. The rotating handle 411 allows the operator to directly grip and apply force, avoiding slippage caused by the smoothness of the screw, while also enabling more precise control of the adjustment range, ensuring that the spacing between the lower support keel 2 and the crossbeam 8 is adjusted properly, thus enhancing the ease of operation.

[0111] 5. High-efficiency connecting keel connectors 5

[0112] The square tube 51 of the keel connector 5 is adapted to the outer contour of the upper supporting keel 1. The double-arm pin 52 can be directly inserted into the horizontal sleeve 3 to extend multiple keels. The connection method is simple and efficient, without the need for welding or complex bolt fixing, thus shortening the construction time. At the same time, the cooperation between the square tube 51 and the double-arm pin 52 can ensure the straightness of the extended keel, avoid uneven support force caused by connection deviation, and improve the overall structural stability of the upper supporting keel 1.

[0113] 6. Stable U-shaped clamps

[0114] After the limiting pin of the U-shaped clamp 6 is inserted into the limiting hole of the horizontal sleeve 3, the upright 7 can be firmly fixed between the two pins, effectively preventing the scaffold upright 7 from shifting due to vibration and load changes, and avoiding support failure caused by the offset of the upright 7. The clamp installation does not require additional drilling or welding, and the operation is simple and quick. It can quickly fix the relative position of the upright 7 and the keel, and strengthen the connection stability between the scaffold and the suspension support structure.

[0115] 7. Inclined beam support system for balanced loads

[0116] The inclined beam support system, through the cooperation of the compression adjustment components 16 on both sides and the tension adjustment components 4 at both ends, enables the lower support keel 2 to form a balanced force state of "tension at both ends and compression in the middle," avoiding local bending or overload of the lower support keel 2 due to the lateral force of the inclined beam 9. At the same time, it takes into account the synchronous support of the floor slab and the inclined beam 9, eliminating the need to design a separate inclined support structure for the inclined beam 9, simplifying the construction process, and adapting to the special support requirements of the inclined beam 9.

[0117] 8. Flexible and adaptable drop plate support system

[0118] The drop slab support system addresses the support requirements of the drop slab 10 structure (where the floor slab height is partially reduced). One end of the lower support keel 2 is suspended by a tension adjustment component 4, allowing for flexible height adjustment to accommodate the drop slab 10's height difference. The other end is mounted on the upright 7 to ensure support stability. This eliminates the need for a separate adjustable upright 7 assembly for the drop slab 10, simplifying the height adaptation structure. Simultaneously, it achieves synchronous support for the floor slab and the drop slab 10, preventing support discontinuities caused by the height difference of the drop slab 10 and improving the structural flatness during the construction of the drop slab 10.

[0119] 9. Space-saving gutter support system

[0120] The gutter support system eliminates the need for uprights 7 below the gutter 11. The lower support keel 2 is suspended from the upper support keel 1 at both ends via tension adjusters 4, utilizing the existing support force of the upper support keel 1 without requiring additional support points. This suspension design allows for flexible adjustment of the distance between the gutter 11 and the lower support keel 2, preventing deformation of the gutter 11 due to improper support and ensuring the construction quality of the gutter 11.

[0121] 10. Highly efficient close-beam support system

[0122] The dense beam support system is designed for the characteristics of the dense beam 12 structure (with closely arranged beams and narrow gaps). The lower support keel 2 is erected on the uprights 7 to support multiple dense beams 12 as a whole, eliminating the need to set up individual support points for each dense beam 12 and improving support efficiency. The upper support keel 1 is set below the floor slab between the dense beams 12 and is suspended from the lower support keel 2 by the tension adjustment component 4. This avoids the upper support keel 1 occupying the space between the dense beams 12 and achieves synchronous support of "dense beams 12-floor slab", which is suitable for the dense layout requirements of the dense beam 12 structure.

[0123] 11. Auxiliary support top support assembly 17

[0124] The slide rail anchor of the top support assembly 17 is fixed to the top groove 31 of the lower support keel 2 via fixed feet, ensuring the stability of the top support position. The bidirectional adjusting screw 41 can flexibly adjust the height of the tray, so that the tray is tightly against the bottom of the upper support keel 1, making up for the small gaps that may occur in the upper support keel 1 due to suspension, and preventing the upper support keel 1 from shaking when under force. The top support assembly 17 can help distribute the load of the upper support keel 1, and is especially suitable for the local stress concentration area of ​​the floor slab with gaps between the beams 12, improving the support strength and stability of the upper support keel 1.

[0125] The scaffolding suspension support structure and its derivative system (horizontal beam 8, inclined beam 9, drop slab 10, gutter 11, and dense beam 12) of this invention, through innovative suspension and adjustment design, achieves integrated support for floor slabs and various irregular structures, significantly improving the space utilization, adjustment flexibility, and construction efficiency of scaffolding in complex construction environments. The design of the bidirectional adjusting screw 41 and upper and lower chucks 43 makes the adjustment of spacing and load distribution more convenient and precise, while the rotating handle 411 and keel connector 5 further simplify construction operations. Auxiliary components such as the U-shaped clamp 6, pressure-bearing adjustment component 16, and top support assembly 17 enhance the stability and reliability of the structure. These designs not only solve the problems of low space utilization, poor adjustment flexibility, uneven load distribution, and low efficiency in existing scaffolding structures for irregular floor slab structures, but also significantly reduce material and labor costs and improve construction quality.

[0126] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0127] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
