Description

Technical Field

[0001] This invention relates to the field of building decoration technology, specifically to an adjustable-angle dry-hanging structure for stone slabs and its construction method. Background Technology

[0002] Currently, most decorative materials such as stone and ceramic tiles on the market adopt a back-bolted dry-hanging structure. The back-bolted dry-hanging structure mainly includes a hook and a hook base with corresponding matching hook grooves. The hook base is fixed to the wall, while the hook is fixed to the back of the stone slab by back bolt anchoring. The stone slab is hung on the hook base by the hook to achieve the dry-hanging effect.

[0003] However, the bolt-on dry-hanging structure, due to its interlocking method using mounting grooves, cannot achieve precise positioning and requires fine-tuning after installation to achieve a good visual effect. Existing technologies typically use mounting brackets that slide within mounting grooves to adjust the horizontal position of the stone slabs. A threaded through-hole is located at the top of the mounting bracket, and a set screw is fitted into this hole. The set screw rests against the mounting base, and its length is adjusted to change the vertical position of the mounting bracket and the stone slab. However, during installation, the stone slabs may partially flip due to gravity, and tilting can easily occur during drilling and anchoring. Ultimately, this results in the stone slabs not being on a single plane, appearing uneven and affecting the overall appearance. Furthermore, adjustment structures for leveling and height are insufficient for adjusting the angle of the stone slabs.

[0004] Therefore, it is necessary to study a dry-hanging structure for stone slabs with adjustable angles. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an adjustable-angle dry-hanging stone slab structure and construction method, which can effectively solve the problem that back-bolted dry-hanging stone slabs are prone to angle deviation but cannot be directly adjusted.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An adjustable-angle dry-hanging structure for stone slabs includes vertical keel, horizontal keel, hanging base, hanging component, stone slab, and angle adjustment device;

[0008] The vertical keel is fixed vertically to the wall, and the horizontal keel is fixed horizontally to the vertical keel. At least two first connectors distributed vertically are fixed on the horizontal keel, and the first connectors have external threads.

[0009] The mounting bracket is fixed on the horizontal keel, the mounting piece is hung on the mounting bracket, and the mounting piece is anchored to the stone slab.

[0010] The angle adjustment device includes a fixed seat, a ball joint seat, and a tensioning rod. The fixed seat is fixed to the inner surface of the stone slab. The fixed seat has at least two second connectors with external threads and symmetrically distributed on both sides of the horizontal keel.

[0011] The tension bar has hinged balls fixed at both ends, and there are corresponding ball hinge seats on the hinged balls on both sides. The corresponding ball hinge seats have threaded holes that are adapted to the corresponding connecting head and are threadedly connected.

[0012] Furthermore, a reinforcing layer is provided on the inner surface of the stone slab; the reinforcing layer includes a wire mesh and a fiberglass mesh, the wire mesh is bonded to the inner surface of the stone slab, the fiberglass mesh is bonded to the outer surface of the wire mesh, and the outer surface of the fiberglass mesh is coated with adhesive.

[0013] The fixing seat is pre-embedded and fixed between the stone slab and the reinforcement layer, and the second connector extends out of the reinforcement layer.

[0014] Furthermore, a third connector is fixed on the horizontal keel, and a fourth connector is provided on the fixing base. The fourth connector extends out a reinforcing layer, and a fall arresting rope is fixedly connected between the third connector and the fourth connector.

[0015] Furthermore, the horizontal keel and the fixing seat are arranged in multiple sets at vertical intervals. The fixing seat has multiple fifth connectors, each of which extends a reinforcing layer. Each fifth connector is fixed with an adapter seat, which has multiple connection points. A fall protection rope is connected between the third connector and the adapter seat, and fall protection ropes are connected between the adapter seats.

[0016] Furthermore, the upper and lower end faces of the horizontal keel are provided with corresponding fixing holes, and threaded rods are inserted into the fixing holes and fixed by nuts. The two ends of the threaded rods extend upward and downward respectively to form the first connectors.

[0017] Furthermore, the upper part of the mounting bracket has a fixing part that extends horizontally toward the wall surface. The fixing part has a through hole that matches the fixing hole. The threaded rod passes through the fixing hole and the through hole and is fixed to the horizontal keel by a nut.

[0018] Furthermore, an elastic gasket is arranged between the fixing part and the cross keel;

[0019] The surface of the fixing part is provided with anti-slip texture, and the upper surface of the fixing part is provided with anti-slip pads;

[0020] The threaded rod passes through the anti-slip pad, through hole, elastic pad and fixing hole to fix the fixing part to the horizontal keel.

[0021] Furthermore, the wall is pre-embedded with embedded parts, the outer surface of the embedded parts is on the same plane as the outer surface of the wall, and the outer surface of the embedded parts is fixed with supports, and the vertical keel is fixedly connected to the wall through the supports.

[0022] Furthermore, the upper part of the mounting base has an upwardly extending first hanging plate, and the lower part of the mounting base has an upwardly opening first hanging groove.

[0023] The upper part of the hook-up piece has a second hanging groove that corresponds to the first hanging plate and opens downwards, and the lower part of the hook-up piece has a second hanging groove that corresponds to the first hanging plate.

[0024] The second hanging plate corresponding to the hanging slot hangs the mounting piece in the mounting bracket.

[0025] A construction method for an adjustable-angle dry-hanging stone slab structure, characterized by the following steps:

[0026] S1: Stone slab treatment;

[0027] Anchor holes are drilled on the inner surface of the stone slab, and corresponding pre-drilled holes are made on the fixing seats. The fixing seats are then placed on the inner surface of the stone slab. A layer of primer is then applied to the inner surface of the stone slab and the surface of the fixing seats. A wire mesh is then laid and bonded to the primer. A second layer of adhesive is applied to the surface of the wire mesh. A fiberglass mesh is then laid on the surface of the wire mesh. Finally, a third layer of adhesive is applied to the surface of the fiberglass mesh to complete the three-adhesive, two-mesh treatment and form a reinforcement layer. The fixing seats are then embedded and fixed between the stone slab and the reinforcement layer. When laying the reinforcement layer, avoidance is made at the connection points of the anchor holes and the fixing seats.

[0028] S2: Fixed vertical keel;

[0029] Based on the layout and grid dimensions of the stone slabs, the vertical keel is positioned on the wall, then the support is fixed on the surface of the embedded parts in the wall, and finally the vertical keel is fixed on the support.

[0030] S3: Fixed transverse keel;

[0031] According to the construction requirements, fixing holes are made on the upper and lower ends of the horizontal keel, and the third connector is fixed on the horizontal keel; then, according to the layout and grid size of the stone slab, the horizontal keel is positioned and fixed on the vertical keel.

[0032] S4: Fixed mounting bracket;

[0033] Elastic pads are arranged on the upper surface of the horizontal keel. The fixing part of the hanger is placed on the horizontal keel through the elastic pads and positioned. The fixing part, elastic pads and horizontal keel are passed through and fixedly connected by a threaded rod, so that the two ends of the threaded rod form the first connector.

[0034] S5: Fix the mounting brackets and hang the stone slabs;

[0035] Position the hanger and anchor it to the inner surface of the stone slab using back bolts;

[0036] The stone slabs are hung on the mounting brackets using the mounting hardware;

[0037] S6: Install tensioning bars;

[0038] Both ends of the tension bar are hinged in the corresponding ball joint seats by hinged ball joints, and then the ball joint seats at both ends of the tension bar are respectively threaded to the first connector of the horizontal keel and the second connector of the fixing seat.

[0039] S7: Install a fall arrest rope;

[0040] Install an adapter on the fifth connector on the fixed seat, connect a fall arresting rope between the third connector on the cross keel and the fourth connector on the fixed seat, connect a fall arresting rope between the third connector and the adapter, and connect fall arresting ropes between each adapter.

[0041] S8: Adjust the stone slab;

[0042] Adjust the thread fit length between the ball joint seat and the first or second connector to tension the tension bar and adjust the angle of the stone slab.

[0043] The beneficial effects of the above technical solution are:

[0044] (1) The present invention has a first connector fixed on the horizontal keel, a fixing seat fixed on the inner surface of the stone slab, a second connector on the fixing seat, and hinge balls fixed at both ends of the tension bar. The hinge balls are hinged with ball hinge seats, and the ball hinge seats have threaded holes adapted to the first connector or the second connector, so that the two ends of the tension bar are threadedly connected to the first and second connectors respectively through the ball hinge seats. By rotating the ball hinge seats, the thread fit length between the ball hinge seats and the first and second connectors is adjusted to adjust the tension and relaxation of the tension bar. The ball hinge connection ensures that the ball hinge seats will not drive the tension bar to rotate when they rotate, thus avoiding shear damage to the tension bar. The tension bar and the corresponding components are symmetrically arranged in two sets according to the horizontal keel. By adjusting the tension of the upper and lower tension bars, the angle of the stone slab can be locally adjusted, which solves the problem that the back-bolted dry-hanging stone slab is prone to angle deviation but cannot be directly adjusted. By directly adjusting the angle of the stone slab, it can be ensured that the stone slab is on a plane and has good appearance quality.

[0045] (2) The present invention adopts a three-adhesive two-mesh pre-embedded structure, which pre-embeds the fixing seat between the reinforcement layer and the stone slab. This can avoid excessive drilling of the stone slab, especially for thinner stone slabs. It solves the problem that drilling holes to fix the fixing seat can easily cause cracks and damage to the stone slab. In addition, the reinforcement layer can further improve the strength of the stone slab, improve the impact resistance of the stone slab, and improve the safety factor.

[0046] (3) By setting up an anti-fall rope, the two ends of the anti-fall rope are fixedly connected to the horizontal keel and the fixed seat respectively. When the stone breaks and falls due to impact or other factors, the part connected to the anti-fall rope will not fall directly, thus avoiding damage to pedestrians or facilities below and improving safety.

Detailed Implementation

[0055] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0056] Example 1: This example aims to provide an adjustable angle stone slab dry-hanging structure and construction method, which is mainly used for dry-hanging decoration of stone, ceramic tiles and other decorative materials. It addresses the problem that back-bolted dry-hanging stone slabs 5 are prone to angle deviations but cannot be directly adjusted.

[0057] An adjustable-angle dry-hanging structure for stone slabs, such as... Figure 1 and Figure 2 It includes vertical keel 1, horizontal keel 2, hanging bracket 3, hanging piece 4, stone slab 5, and angle adjustment device; embedded parts 13 are pre-embedded in the wall 12, and the embedded parts 13 are metal components, such as... Figure 1 The outer surface of the embedded part 13 is on the same plane as the outer surface of the wall 12. The outer surface of the embedded part 13 is welded and fixed with a support 14. The side wall of the support 14 has bolt holes. The vertical keel 1 is vertically fixed to the support 14 by a high-strength bolt assembly.

[0058] The horizontal keel 2 is horizontally welded and fixed to the vertical keel 1. The horizontal keel 2 is a square steel tube structure. The upper and lower end faces of the horizontal keel 2 are provided with corresponding fixing holes. A threaded rod 203 is inserted into the fixing hole and fixed by a nut. The two ends of the threaded rod 203 extend upward and downward respectively to form the first connector 201. In other embodiments, the bolt head can also be set inside the horizontal keel 2 and the threaded end extends outward by means of gecko bolts, etc. The outwardly extending threaded end is the first connector 201.

[0059] like Figure 2 The upper part of the mounting bracket 3 has a fixing part 303 extending horizontally towards the surface of the wall 12. The fixing part 303 has a through hole that matches the fixing hole. The threaded rod 203 passes through the fixing hole and the through hole and is fixed to the horizontal keel 2 by a nut. In order to further improve the fit, form prestressed reinforcement, and reduce wear between the reinforcement part and the horizontal keel 2, an elastic gasket 304 is arranged between the fixing part 303 and the horizontal keel 2. The surface of the fixing part 303 is provided with serrated anti-slip texture, and the upper surface of the fixing part 303 is provided with an anti-slip gasket 305 with serrated anti-slip texture. The threaded rod 203 passes through the anti-slip gasket 305, the through hole, the elastic gasket 304 and the fixing hole, and fixes the fixing part 303 and the horizontal keel 2 together. The upper part of the mounting base 3 has an upwardly extending first hanging plate 301, and the lower part of the mounting base 3 has an upwardly opening first hanging groove 302; the upper part of the mounting member 4 has a second hanging groove 402 corresponding to the first hanging plate 301 and opening downward, and the lower part of the mounting member 4 has a second hanging plate 401 corresponding to the first hanging groove 302. The mounting member 4 is hung in the mounting base 3; a reserved through hole is opened in the middle of the mounting member 4, and an anchoring hole is opened on the stone slab 5. The mounting member 4 is anchored to the inner surface of the stone slab 5 by a back bolt.

[0060] The inner surface of the stone slab 5 is provided with a reinforcing layer 9, such as... Figure 3 The reinforcing layer 9 includes a wire mesh 901 and a fiberglass mesh 902. The wire mesh 901 is bonded to the inner surface of the stone slab 5, and the fiberglass mesh 902 is bonded to the surface of the wire mesh 901. The surface of the fiberglass mesh 902 is also coated with a layer of adhesive 903 to form a three-adhesive, two-mesh treatment to further improve the strength of the stone slab 5. The angle adjustment device includes a fixing seat 6, a ball joint seat 7, and a tensioning rod 8. The fixing seat 6 has at least two second connectors 601. The second connectors 601 have external threads and are symmetrically distributed on both sides of the horizontal keel 2. The second connectors 601 can be welded to the fixing seat 6, or they can be formed by screws passing through the fixing seat 6 from the back. The fixing seat 6 is pre-embedded and fixed between the stone slab 5 and the reinforcing layer 9. The second connectors 601 extend out of the reinforcing layer 9. In other embodiments, the fixing seat 6 can also be fixed to the inner surface of the stone slab 5 by anchoring.

[0061] like Figure 4 The tensioning tendon is made of steel strand with threads at both ends. The two ends of the tensioning tendon 8 are threadedly connected to hinged balls 801, which are hinged in a ball hinge seat 7. The ball hinge seat 7 has threaded holes 701 adapted to the first connector 201 or the second connector 601. The two ends of the tensioning tendon 8 are threadedly connected to the first and second connectors 601 respectively through the ball hinge seat 7. By rotating the ball hinge seat 7, the thread fit length between the ball hinge seat 7 and the first and second connectors 601 is adjusted, thereby adjusting the tension and relaxation of the tensioning tendon 8. The ball hinge connection ensures that the ball hinge seat 7 will not rotate when rotating, avoiding shear damage to the tensioning tendon 8. Two sets of tensioning tendons 8 and corresponding components are symmetrically arranged above and below the horizontal keel 2. By adjusting the tension of the upper and lower tensioning tendons 8, the angle of the stone slab 5 can be locally adjusted. Figure 2 In the optimal state, the stone slab 5 and the threaded rod 203 remain parallel, and the stone slab 5, the threaded rod 203 and the two tensioning bars together form an isosceles trapezoid.

[0062] To prevent damage to pedestrians or facilities below in the event of stone breaking and falling due to impact or other factors, a fall arrest rope 10 has been installed. Figure 5 A third connector 202 is fixed on the horizontal keel 2. The structure of the third connector 202 is the same as that of the first connector 201, and it has external threads. A fourth connector 602 is provided on the fixing seat 6. The structure of the fourth connector is the same as that of the second connector 601, and it has external threads and extends out a reinforcing layer 9. Both ends of the fall arrest rope 10 are provided with ball joint seats 7. The ends of the fall arrest rope 10 are fixed in the ball joint seats 7 by tying knots, and are fixedly connected to the third and fourth connectors 602 through the ball joint seats 7.

[0063] A construction method for an adjustable-angle dry-hanging stone slab structure includes the following steps:

[0064] S1: Stone slab with 5-stage treatment;

[0065] Anchor holes are made on the inner surface of the stone slab 5, and corresponding reserved holes are made on the fixing seat 6. The fixing seat 6 is arranged on the inner surface of the stone slab 5. Then, a layer of primer is applied to the inner surface of the stone slab 5 and the surface of the fixing seat 6. The wire mesh 901 is fully laid and bonded to the primer. A second layer of adhesive is applied to the surface of the wire mesh 901. Fiberglass mesh 902 is fully laid on the surface of the wire mesh 901. Finally, a third layer of adhesive is applied to the surface of the fiberglass mesh 902 to complete the three-adhesive and two-mesh treatment and form the reinforcement layer 9. The fixing seat 6 is pre-embedded and fixed between the stone slab 5 and the reinforcement layer 9. When laying the reinforcement layer 9, avoidance is made at each connection point on the anchor holes and the fixing seat 6.

[0066] S2: Fixed vertical keel 1;

[0067] According to the layout and grid size of the stone slab 5, the vertical keel 1 is positioned on the wall 12, and then the support 14 is fixed on the surface of the embedded part 13 of the wall 12. Finally, the vertical keel 1 is fixed on the support 14.

[0068] S3: Fixed transverse keel 2;

[0069] According to the construction requirements, fixing holes are made on the upper and lower end faces of the horizontal keel 2, and the third connector 202 is fixed on the horizontal keel 2; then, according to the layout and grid size of the stone slab 5, the horizontal keel 2 is positioned and fixed on the vertical keel 1.

[0070] S4: Fixed mounting bracket 3;

[0071] An elastic gasket 304 is arranged on the upper surface of the horizontal keel 2. The fixing part 303 of the hook seat 3 is arranged on the horizontal keel 2 through the elastic gasket 304 and positioned. The fixing part 303, the elastic gasket 304 and the horizontal keel 2 are passed through and fixedly connected by a threaded rod 203, so that the two ends of the threaded rod 203 form the first connector 201.

[0072] S5: Fix the mounting bracket 4 and hang the stone slab 5;

[0073] Position the hanger 4 and anchor it to the inner surface of the stone slab 5 using back bolts.

[0074] The stone slab 5 is hung on the mounting bracket 3 via the mounting bracket 4;

[0075] S6: Install tensioning rod 8;

[0076] Both ends of the tension bar 8 are ball-hinged in the corresponding ball-hinged seats 7 via the hinge ball 801, and then the ball-hinged seats 7 at both ends of the tension bar 8 are respectively threaded onto the first connector 201 of the horizontal keel 2 and the second connector 601 of the fixing seat 6.

[0077] S7: Install a 10mm anti-fall rope;

[0078] A ball joint seat 7 is threaded through each end of the fall arrest rope 10. Then, the ends of the fall arrest rope 10 are knotted to fix the ball joint seat 7 to the fall arrest rope 10. The ends of the fall arrest rope 10 are connected to the third connector 202 on the horizontal keel 2 and the fourth connector 602 on the fixed seat 6 through the ball joint seat 7.

[0079] S8: Adjust the stone slab size by 5;

[0080] Adjust the thread fit length between the ball joint seat 7 and the first or second connector to tension the tension bar 8. There are two tension bars 8 in a set, symmetrically arranged on both sides of the horizontal keel 2. Adjust the tension of the two tension bars 8 to adjust the angle of the stone slab 5.

[0081] Example 2 is basically the same as Example 1, except that the arrangement of the fall arrest ropes 10 is optimized and the various fall arrest ropes 10 are connected to each other so that if a connection point of one fall arrest rope 10 fails, the fall arrest function can be maintained by relying on the connection points of other fall arrest ropes 10. This example further describes the structure.

[0082] In this embodiment, as Figure 6 The fixed base 6 has multiple fifth connectors 603. The fifth connectors 603 have the same structure as the second and fourth connectors, and all extend a reinforcing layer 9. Each fifth connector 603 is threaded with an adapter 11. The adapter 11 has multiple connection points. A fall arrest rope 10 is connected between the third connector and the adapter. Fall arrest ropes 10 are connected between the adapters. The connection method between the fall arrest ropes 10 and each connection point is the same as in Embodiment 1.

[0083] The installation steps of the fall arrest rope 10 in this embodiment are as follows: install an adapter on the fifth connector 603 on the fixed seat 6, connect the fall arrest rope 10 between the third connector 202 on the horizontal keel 2 and the fourth connector 602 on the fixed seat 6, connect the fall arrest rope 10 between the third connector 202 and the adapter 11, and connect the fall arrest rope 10 between each adapter 11.

[0084] When the stone slab 5 is impacted or subjected to impact force due to falling, the connection point 602 on the fixed seat 6 is directly connected to the stone slab 5, and especially when the connection point is anchored, the connection position between the fall arrest rope 10 and the fourth connection point is most likely to be damaged and fail. By adopting the structure of the fifth connector 603 and the adapter, the fall arrest ropes 10 arranged vertically can be connected in series, and the adapter can be directly connected to the fixed seat 6. When the connection between the adapter and the fixed seat 6 is damaged and fails, the fall arrest ropes 10 connected to the adapter can still remain connected together, and the next adapter can be used as a support point, which improves the redundancy of the fall arrest structure and avoids the problem that the failure of a single connection point due to local damage near the impact point will cause the entire fall arrest rope 10 to fail, thus improving the stability of the entire fall arrest structure.

[0085] Example 3 is basically the same as Example 1, except that the expansion and contraction structure of the tensioning tendon is optimized, making the tensioning tendon easier to adapt to different length requirements and having a larger tension adjustment range. This example further describes the structure.

[0086] In this embodiment, the tensioning wire 8 is still made of steel strand, such as Figure 7 The tension bar 8 consists of two sections of steel strands, both ends of which have external threads. The two sections of steel strands are connected by a threaded sleeve. Due to the ball joint structure, the steel strands can rotate freely. By holding the threaded sleeve, the length of the steel strands in the threaded sleeve can be rotated to adjust the length of the entire tension bar 8, which can be used to adapt to different length requirements of the tension bar 8. In use, the length of the entire steel strand is first adjusted by the threaded sleeve, and then the tension of the tension bar 8 is adjusted by adjusting the thread engagement length between the ball joint seat 7 and the first and second connecting heads, thereby adjusting the angle of the stone slab 5.

Finally, a third layer of adhesive is applied to the surface of the fiberglass mesh to complete the three-adhesive, two-mesh treatment and form a reinforcement layer. The fixing seats are then embedded and fixed between the stone slab and the reinforcement layer. When laying the reinforcement layer, avoidance is made at the connection points of the anchor holes and the fixing seats. S2: Fixed vertical keel; Based on the layout and grid dimensions of the stone slabs, position the vertical keel on the wall, then fix the support on the surface of the embedded parts in the wall, and finally fix the vertical keel on the support. S3: Fixed transverse keel; According to the construction requirements, fixing holes are made on the upper and lower ends of the horizontal keel, and the third connector is fixed on the horizontal keel; then, according to the layout and grid size of the stone slab, the horizontal keel is positioned and fixed on the vertical keel. S4: Fixed mounting bracket; Elastic pads are arranged on the upper surface of the horizontal keel. The fixing part of the hanger is placed on the horizontal keel through the elastic pads and positioned. The fixing part, elastic pads and horizontal keel are passed through and fixedly connected by a threaded rod, so that the two ends of the threaded rod form the first connector. S5: Fix the mounting brackets and hang the stone slabs; Position the hanger and anchor it to the inner surface of the stone slab using back bolts; The stone slabs are hung on the mounting brackets using the mounting hardware; S6: Install tensioning bars; Both ends of the tension bar are hinged in the corresponding ball joint seats by hinged ball joints. Then the ball joint seats at both ends of the tension bar are respectively threaded to the first connector of the horizontal keel and the second connector of the fixing seat. S7: Install a fall arrest rope; Install an adapter on the fifth connector on the fixed seat, connect a fall arresting rope between the third connector on the cross keel and the fourth connector on the fixed seat, connect a fall arresting rope between the third connector and the adapter, and connect fall arresting ropes between each adapter. S8: Adjust the stone slab; Adjust the thread fit length between the ball joint seat and the first or second connector to tension the tension bar and adjust the angle of the stone slab.
