Description

Technical Field

[0001] This invention relates to the field of corner decorative stone panel connection technology, and in particular to a bidirectional, multi-angle adjustable connection device. Background Technology

[0002] With the development of the times, the requirements for the exterior decoration of buildings are getting higher and higher. Traditional straight square or circular buildings can no longer meet the expression needs of modern buildings. As a result, various new types of buildings are constantly emerging. The facade of buildings has gradually evolved from the simple and flat facade to a complex composition of multiple corners, curved surfaces and other structures. Free-form surface structures have become one of the main trends in the development of spatial structures with their excellent architectural expressiveness and are being used in more and more large-span building projects.

[0003] Currently, the connectors for the decorative stone panels at curved corners are independent of each other, each supporting the decorative stone panel on its own. The connection stability between them is poor. Furthermore, during installation, it is necessary to measure the installation position of each connector and the angle between the decorative stone panels. After multiple measurements, errors can easily accumulate, leading to reduced installation accuracy. Moreover, it is difficult to meet the requirements for water tightness between the gaps of the decorative stone panels at corners. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a bidirectional, multi-angle adjustable connection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bidirectional, multi-angle adjustable connection device, comprising:

[0007] First support plate and second support plate: The first support plate and the second support plate are respectively provided with fixing holes, and there are at least two fixing holes. The outer side of the first support plate and the second support plate is an external mounting surface that is connected to the wall, and the inner side has an internal mounting surface.

[0008] The first support plate includes a first fixing part and a first adjusting part; the second support plate includes a second fixing part and a second adjusting part; wherein the first fixing part and the second fixing part are fixed to the mounting surface of the wall respectively, and the corresponding adjusting part is arranged inside the fixing part. The first adjusting part is alternately arranged with a first arc-shaped plate and an arc-shaped groove, and the second adjusting part is alternately arranged with an arc-shaped groove and a second arc-shaped plate. The first arc-shaped plate and the second arc-shaped plate and the arc-shaped groove can be fitted together and can slide.

[0009] Fixing component: The fixing component passes through at least one set of first arc-shaped clamping plates and second arc-shaped clamping plates from the outside, fixing the first arc-shaped clamping plates and the second arc-shaped clamping plates relative to each other.

[0010] A further technical solution of the present invention is that the adjusting part is installed at the edge of the corresponding fixing part near the corner of the decorative stone panel, so that the adjusting part is closer to the decorative stone panel.

[0011] A further technical solution of the present invention is that the fixing member is a dovetail screw, which is spirally drilled into the first arc-shaped clamping plate and the second arc-shaped clamping plate to fix it.

[0012] A further technical solution of the present invention is that an extension plate is fixed at the junction of the fixing part and the adjusting part of the first support plate and the second support plate, and the extension plate is parallel to the corresponding fixing part. An accommodating area is formed between the first arc-shaped clamping plate, the second arc-shaped clamping plate and the two extension plates. An elastic steel sheet is fixed in the accommodating area by a limiting mechanism. A caulking foam strip is provided between the elastic steel sheet and the two decorative stone panels. The middle area of ​​the elastic steel sheet bends toward the gap between the two decorative stone panels, and the caulking foam strip contacts the elastic steel sheet and the two decorative stone panels. The caulking foam strip gradually shrinks toward the gap between the two decorative stone panels.

[0013] A further technical solution of the present invention is that the limiting mechanism includes snap-fit ​​blocks fixed on both sides of the elastic steel sheet, and a blocking strip is fixed on the extension plate. The two ends of the elastic steel sheet are limited by the blocking strip through the snap-fit ​​blocks.

[0014] A further technical solution of the present invention is that two limiting plates are fixedly connected to the elastic steel sheet, and the caulking foam strip is stuck between the two limiting plates.

[0015] A further technical solution of the present invention is that the blocking strips are configured as a plurality of ones and arranged symmetrically on two extension plates.

[0016] A further technical solution of the present invention is that a snap-fit ​​groove is provided on the inner side of the blocking strip, and the snap-fit ​​block is adapted to the snap-fit ​​groove.

[0017] A further technical solution of the present invention is that the second support plate is fixedly connected to a first angle indicator plate parallel to the contact surface of the second support plate and the decorative stone plate by a connecting rod, and the first support plate is fixedly connected to a second angle indicator plate parallel to the contact surface of the first support plate and the decorative stone plate by a connecting rod, and the first angle indicator plate and the second angle indicator plate are in staggered contact.

[0018] A further technical solution of the present invention is that a protractor is fixed on the second angle indicator plate, and an indicator line parallel to the contact surface of the second support plate and the decorative stone plate is opened on the surface of the first angle indicator plate facing the protractor.

[0019] Compared with the prior art, the present invention provides a bidirectional multi-angle adjustable connection device, which has the following beneficial effects.

[0020] 1. The first and second arc-shaped clamping plates of this invention interlock through a clearance zone, allowing the first and second arc-shaped clamping plates to rotate around their concentric point while being limited by each other. This adjusts the angle between the first and second support plates, making operation simple and convenient. The first and second arc-shaped clamping plates support and limit each other, increasing the connection strength. Combined with dovetail screws to limit the first and second arc-shaped clamping plates, the decorative stone panels connected to the first and second support plates are more stable, eliminating the safety hazard of the decorative stone panels falling from heights. The included angle between the first and second angle indicator plates can be easily adjusted by observing a protractor and indicator lines, eliminating the need for multiple measurements and ensuring high installation accuracy.

[0021] 2. This invention, by setting several blocking strips, can adjust the position of the elastic steel sheet within the receiving area. The locking blocks and locking grooves can limit the movement of the elastic steel sheet. When the first and second support plates rotate relative to each other, the elastic steel sheet bends towards the gap between the two facing stone panels under the obstruction of the blocking strips and locking blocks, allowing the elastic steel sheet to apply pressure to the caulking foam strip. Combined with the sealant applied to the caulking foam strip, this improves the sealing performance of the caulking foam strip over the gap between the facing stone panels. The rubber pads ensure a tight connection between the first support plate and the facing stone panel, and between the second support plate and the facing stone panel. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figure 1-6 A bidirectional, multi-angle adjustable connection device includes a first support plate 1 and a second support plate 2. The first support plate 1 is installed on a decorative stone panel 11 at a corner via a connecting back bolt 10 and a fixing hole 18. There are at least two fixing holes 18 to ensure the stability of the connection between the first support plate 1 and the second support plate 2 and the wall. The connecting back bolt 10 is made of stainless steel. The second support plate 2 is installed on another decorative stone panel 11 at a corner via the connecting back bolt 10 and the fixing hole 18. Rubber pads 9 are provided between the first support plate 1 and the decorative stone panel 11 and between the second support plate 2 and the decorative stone panel 11 to ensure a tight connection.

[0032] The outer sides of the first support plate 1 and the second support plate 2 are external mounting surfaces that connect to the wall, and their inner sides have internal mounting surfaces. The first support plate 1 includes a first fixing part and a first adjusting part; the second support plate 2 includes a second fixing part and a second adjusting part. The first fixing part and the second fixing part are fixed to the mounting surface of the wall, and the corresponding adjusting part is set inside the fixing part. The first adjusting part is alternately arranged with a first arc-shaped clamping plate 3 and an arc-shaped groove, and the second adjusting part is alternately arranged with an arc-shaped groove and a second arc-shaped clamping plate 8. The first arc-shaped clamping plate 3 and the second arc-shaped clamping plate 8 can be fitted into each other and slide, so that the first arc-shaped clamping plate 3 and the second arc-shaped clamping plate 8 can rotate the first support plate 1 and the second support plate 2 around their concentric point under the limitation of each other, thereby adjusting the angle between the first support plate 1 and the second support plate 2. The operation is simple and convenient.

[0033] The first arc-shaped clamping plate 3 and the second arc-shaped clamping plate 8 are connected by dovetail screws 4 that spirally penetrate the first arc-shaped clamping plate 3 and the second arc-shaped clamping plate 8. The dovetail screws are an improved design of self-tapping screws, which are less likely to cause material cracking during use and can better play a fixing role. By drilling the dovetail screws 4 into the first arc-shaped clamping plate 3 and the second arc-shaped clamping plate 8, the first arc-shaped clamping plate 3 and the second arc-shaped clamping plate 8 can be fixed. The interlocking first arc-shaped clamping plates 3 and the second arc-shaped clamping plates 8 can support and limit each other, increasing the connection strength between the first support plate 1 and the second support plate 2. Combined with the dovetail screws 4 limiting the first arc-shaped clamping plate 3 and the second arc-shaped clamping plate 8, the decorative stone slab 11 connected to the first support plate 1 and the second support plate 2 is more stable, eliminating the safety hazard of the decorative stone slab 11 falling off from a height.

[0034] The second support plate 2 is fixedly connected to a first angle indicator plate 5, which is parallel to the contact surface between the second support plate 2 and the facing stone slab 11, via a connecting rod. The first support plate 1 is fixedly connected to a second angle indicator plate 7, which is parallel to the contact surface between the first support plate 1 and the facing stone slab 11, via a connecting rod. The first angle indicator plate 5 and the second angle indicator plate 7 are in staggered contact, so that the included angle between the first angle indicator plate 5 and the second angle indicator plate 7 is the same as the included angle between the first support plate 1 and the second support plate 2. A protractor 6 is fixed on the second angle indicator plate 7. An angle indicator line is provided on the upper part, and the surface of the first angle indicator plate 5 facing the protractor 6 has an indicator line parallel to the contact surface of the second support plate 2 and the decorative stone plate 11. By observing the protractor 6 and the indicator line, the included angle between the first angle indicator plate 5 and the second angle indicator plate 7 can be determined. Thus, the angle between the first support plate 1 and the second support plate 2 can be easily adjusted according to the angle requirements of the corner, so that the angle between the first support plate 1 and the second support plate 2 matches the angle between the decorative stone plates 11 at the corner. No multiple measurements are required, and the installation accuracy is high.

[0035] An extension plate 13 is fixed at the junction of the fixing part and the adjusting part of the first support plate 1 and the second support plate 2. A receiving area is formed between the first arc-shaped clamping plate 3, the second arc-shaped clamping plate 8, and the two extension plates 13. A caulking foam strip 16 is installed within this receiving area. The caulking foam strip 16 is an existing technology product, primarily used to fill excessively deep gaps, preventing rainwater leakage and saving on sealant, thus reducing costs. In use, simply place the foam strip under the surface of the stone to be bonded, and then apply adhesive. An elastic steel sheet 17 is installed within the receiving area. The caulking foam strip 16, the elastic steel sheet 17, and the corner... Two decorative stone panels 11 are in contact and sealant is applied to them to seal the gap between the two decorative stone panels 11. Two limiting plates 15 are fixedly connected to the elastic steel sheet 17, and the joint filling foam strip 16 is located between the two limiting plates 15. The two limiting plates 15 provide pressure to the joint filling foam strip 16, so that the joint filling foam strip 16 is stuck in the two limiting plates 15. There are snap-fit ​​blocks 14 fixed on both sides of the elastic steel sheet 17. Several blocking strips 12 are fixed on the extension plate 13, and the blocking strips 12 are provided with snap-fit ​​grooves 19 to accommodate the snap-fit ​​blocks 14. The snap-fit ​​blocks 14 are snapped into the corresponding snap-fit ​​grooves 19.

[0036] By setting several blocking strips 12, the position of the elastic steel sheet 17 in the receiving area can be adjusted. By setting the snap-fit ​​block 14 and snap-fit ​​groove 19, the elastic steel sheet 17 can be limited. When the first support plate 1 and the second support plate 2 rotate relative to each other, the elastic steel sheet 17 bends towards the gap between the two decorative stone panels 11 under the obstruction of the blocking strips 12 and snap-fit ​​block 14, so that the elastic steel sheet 17 provides pressure to the caulking foam strip 16, making the caulking foam strip 16 better seal the gap between the decorative stone panels 11.

[0037] Working principle: During installation, pre-drilled holes are made on the facing stone panel 11. The fixing holes 18 on the first support plate 1 and the second support plate 2 are aligned with the pre-drilled holes. Rubber pads 9 are placed between the first support plate 1 and the facing stone panel 11 and between the second support plate 2 and the facing stone panel 11. The connecting back bolts 10 are inserted into the fixing holes and the pre-drilled holes, thereby installing the first support plate 1 and the second support plate 2 on the facing stone panel 11. Then, the first arc-shaped clamping plate 3 and the second arc-shaped clamping plate 8 are interlaced, and the elastic steel sheet 17 is installed in a suitable position in the receiving area through the clamping block 14 and the clamping groove 19. The caulking foam strip 16 is clamped between the two limiting plates 15. According to the required angle between the facing stone panels 11, the protractor 6 and the indicator line are observed to determine the first angle. The included angle between the indicator plate 5 and the second angle indicator plate 7 causes the first support plate 1 and the second support plate 2 to rotate relative to each other, thereby adjusting the angle between the first support plate 1 and the second support plate 2. At the same time, when the first support plate 1 and the second support plate 2 rotate relative to each other, the middle area of ​​the elastic steel sheet 17 bends towards the gap between the two decorative stone panels 11 under the obstruction of the blocking strip 12 and the snap-fit ​​block 14, thereby providing pressure to the caulking foam strip 16, so that the caulking foam strip 16 contacts the gap between the two decorative stone panels 11 and injects sealant to provide a seal. After the adjustment is completed, the first support plate 1 and the second support plate 2 are fixed relative to each other by drilling the dovetail screw 4 into the first arc-shaped snap-fit ​​plate 3 and the second arc-shaped snap-fit ​​plate 8. Thus, the installation of this device is completed.
