Description

Technical Field

[0001] The utility model relates to the technical field of building curtain walls, and particularly relates to a corner connection and fixing structure for linear stone veneer panels. Background Technique

[0002] In modern construction engineering practice, traditional connection methods such as gluing or angle steel connection are often used at the corners of linear stone veneer panels. Although this method can achieve the basic stability of the structure initially, over time and under the influence of environmental factors, these connection nodes are prone to loosening and deformation, and the stiffness is also insufficient. Especially in the curtain wall applications of high-rise buildings, this problem is particularly prominent. Under the action of natural forces such as strong winds, the corner stones often become loose, deformed or even fall off. And because there are often no obvious signs of damage on the surface of this structure, its concealment and unpredictability greatly increase the potential danger. For the linear stone panels located at high altitudes, once the corner stones fall off, it is very likely to cause serious high-altitude falling object accidents, posing a major threat to the lives of pedestrians and surrounding property.

[0003] Therefore, redesigning a more stable and safe stone corner connection method has become an urgent need in the current construction engineering field. This need not only concerns the progress of technology, but is also an important link in ensuring public safety and promoting the sustainable development of buildings.

[0004] Based on this, it is necessary to study a corner connection and fixing structure for linear stone veneer panels. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a corner connection and fixing structure for linear stone veneer panels, which can effectively solve the problem that the corner connection of linear stones has poor stiffness and is easy to loosen and fall off.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A corner connection and fixing structure for linear stone veneer panels, comprising a first stone panel, a second stone panel, a strengthening pin plate and a corner fixing member;

[0008] The first stone panel is fixedly connected to the wall structure, the first stone panel is vertically spliced with the second stone panel, and the splicing surfaces of the first stone panel and the second stone panel facing each other are inclined surfaces;

[0009] Fixing grooves are arranged along the length direction on the splicing surfaces of the first stone panel and the second stone panel, and the two fixing grooves are vertically arranged with respect to each other and the groove openings face each other;

[0010] The reinforcing pin plate has a right-angled plate-like structure, including a first pin plate and a second pin plate arranged perpendicular to each other; both the first pin plate and the second pin plate are adapted to the fixing grooves, and are respectively inserted and adhesively fixed in the fixing grooves of the first stone plate and the second stone plate;

[0011] The corner fixing member is right-angled, including a first fixing portion and a second fixing portion arranged perpendicular to each other, and both the first fixing portion and the second fixing portion are respectively anchored and connected to the first stone plate and the second stone plate through back bolts.

[0012] Furthermore, the first pin plate and the second pin plate are fixedly connected by an inclined connecting plate, and both ends of the connecting plate are respectively fixed to the inner surfaces of the first pin plate and the second pin plate;

[0013] The first fixing portion and the second fixing portion are fixedly connected by an inclined hypotenuse rib, and both ends of the hypotenuse rib are respectively fixed to the inner surfaces of the first fixing portion and the second fixing portion.

[0014] Furthermore, a gap is reserved between the splicing surfaces of the first stone plate and the second stone plate, and the outer end of the gap is filled with sealant.

[0015] Furthermore, it further includes a connecting member; the connecting plate and the hypotenuse rib are arranged in parallel and both are provided with corresponding through holes, and the connecting member passes through the through holes to fixedly connect the connecting plate and the hypotenuse rib into a whole.

[0016] Furthermore, cushion grooves are respectively provided on the contact surfaces of the first fixing portion with the first stone plate and the second fixing portion with the second stone plate, and buffer pads are arranged in the cushion grooves.

[0017] Furthermore, a Begonia corner is provided at the corner where the first stone plate and the second stone plate meet.

[0018] Furthermore, the outer surface of the reinforcing pin plate is a serrated surface.

[0019] The beneficial effects of the above technical solutions are:

[0020] (1) In the present utility model, at the corner position of the stone slab, two corner stone slabs are fixedly connected together by using corner fixing pieces and back bolts for anchoring connection, ensuring the shear resistance and bending resistance strength at the corner position. Especially under high wind pressure or physical impact conditions, the structural integrity of the corner is more reliable. Then, by opening a fixing groove at the corner and fixing a reinforcing pin plate, and using chemical bonding to further reinforce and connect the two corner stone slabs, additional physical support is provided, ensuring the tight connection between the first stone slab and the second stone slab at the corner, making the splicing surface more stable structurally, reducing looseness or displacement caused by insecure connection, and helping to improve the overall rigidity and durability of the corner connection, especially when facing external pressures such as wind force or vibration. In summary, the present utility model improves the rigidity of the corner stone connection, improves the stress condition of the corner of the linear stone, effectively solves the problem that the connection stiffness of the corner of the linear stone is poor and it is easy to loosen and fall off, avoids the safety hazard of the stone line falling off caused by the sudden breakage due to the deformation of the corner stone, and improves the safety and reliability of the structure.

[0021] (2) The present utility model uses an inclined connecting plate to connect the first pin plate and the second pin plate, and uses an inclined hypotenuse rib to connect the first fixing part and the second fixing part, avoiding potential weaknesses of the right-angle structure such as stress concentration, thereby enhancing the overall stability and fracture resistance of the structure.

[0022] (3) A gap is reserved between the splicing surfaces of the first stone slab and the second stone slab of the present utility model, which can avoid contact extrusion between the splicing surfaces due to deformation, allow the material to expand or contract naturally under the influence of temperature change or other environmental factors, improve the adaptability and elasticity of the entire structure, and enhance the service life of the structure.

[0023] (4) By using the gap between the splicing surfaces, a connecting member is passed through between the connecting plate and the hypotenuse rib, so that the corner fixing piece and the reinforcing rib plate are fixedly connected into a whole, greatly enhancing the overall stiffness of the structure, being able to evenly disperse the stress at the joints and connection points, reducing structural damage caused by uneven loading, helping to resist deformation caused by external forces (such as wind pressure, etc.), and ensuring the stability and safety of the structure during long-term use.

Detailed implementation mode

[0030] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes:

[0031] Example 1. This example aims to provide a corner connection and fixing structure for linear stone veneers, which is mainly used for the construction of stone veneer curtain walls to address the problem of poor stiffness and easy loosening and falling off of the corner connection of linear stone veneers.

[0032] A corner connection and fixing structure for linear stone veneers, as Figure 1 , includes a first stone slab 1, a second stone slab 2, a reinforcing pin plate 3 and a corner fixing part 4; the first stone slab 1 is fixedly connected to the wall structure 5. In this example, the wall structure 5 is the fixing foundation of the curtain wall stone slab, including angle steel for the skeleton structure and stone hanging pieces for connecting the first stone slab 1. The left and right ends of the first stone slab 1 are cut into 45° bevel angles, and the second stone slabs 2 are vertically arranged at the left and right ends of the first stone slab 1. The ends of the second stone slabs 2 corresponding to the splicing with the first stone slab 1 are also cut out 45° bevel angles, so that the opposite splicing surfaces 101 of the first stone slab 1 and the second stone slab 2 are inclined planes and form an inclined plane splicing; further, as Figure 2 , the bevel angles of the first stone slab 1 and the second stone slab 2 are 45° Begonia angle 104 structures, so that the formed corner after splicing forms a Begonia angle 104 instead of a right-angle side, reducing damage to people or the corner structure caused by bumping, and at the same time being more ornamental.

[0033] As Figure 1 and Figure 2 , fixing grooves 102 are arranged along the length direction on the splicing surfaces 101 of the first stone slab 1 and the second stone slab 2. The specifications of the two fixing grooves 102 are the same and are located at the thickness center of the stone slab. The two fixing grooves 102 are vertically arranged relative to each other and the groove openings are opposite, and openings are provided at the groove openings; the fixing grooves 102 are vertically arranged and openings are also made at the upper ends to facilitate the insertion of the reinforcing pin plate 3.

[0034] AsFigure 3 The reinforcing pin plate 3 is in a right-angled plate-like structure, including a first pin plate 301 and a second pin plate 302 which are arranged perpendicular to each other. The first pin plate 301 and the second pin plate 302 are integrally formed structures. The first pin plate 301 and the second pin plate 302 respectively match the fixing grooves 102 and are respectively inserted into the fixing grooves 102 of the first stone plate 1 and the second stone plate 2. Structural adhesive layers 103 are filled between the fixing grooves 102 and the first pin plate 301 and the second pin plate 302 to further bond and fix them, and the reinforcing pin plate 3, the first stone plate 1 and the second stone plate 2 are fixedly connected into a whole.

[0035] Further, in order to improve the bonding effect, Figure 3 the outer surface of the reinforcing pin plate 3 is a serrated surface, which is convenient for hiding glue and increases the bonding contact area, thereby improving the bonding strength.

[0036] such as Figure 1 and Figure 4 the corner fixing part 4 is in a right-angled shape, including a first fixing part 401 and a second fixing part 402 which are arranged perpendicular to each other. The first fixing part 401 and the second fixing part 402 are respectively anchored and connected to the back surfaces of the first stone plate 1 and the second stone plate 2 through back bolts 6.

[0037] Further, the first fixing part 401 and the second fixing part 402 are fixedly connected through an inclined hypotenuse rib 403. The two ends of the hypotenuse rib 403 are respectively fixed to the inner surfaces of the first fixing part 401 and the second fixing part 402, avoiding potential weaknesses of the right-angled structure such as stress concentration, thereby enhancing the overall stability and anti-fracture ability of the structure. A cavity is provided in the middle of the hypotenuse rib 403 to reduce and uniform the wall thickness, thereby reducing the self-weight.

[0038] Further, a gap is reserved between the splicing surfaces 101 of the first stone plate 1 and the second stone plate 2. The reserved gap can prevent the splicing surfaces 101 from coming into contact and extrusion due to deformation, allowing the material to expand or contract naturally under the influence of temperature changes or other environmental factors, improving the adaptability and elasticity of the whole structure, and enhancing the service life of the structure. The outer ends of the gap are filled with sealant 7. The sealant 7 can prevent external moisture and sundries from entering the interior of the stone plate connection structure, reduce the loss rate, improve the service life, and at the same time can increase the aesthetics.

[0039] Further, cushion grooves 404 are provided on the contact surfaces between the first fixing part 401 and the first stone plate 1 and between the second fixing part 402 and the second stone plate 2. Buffer pads 9 are arranged in the cushion grooves 404 to reduce the damage caused by contact extrusion.

[0040] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that this embodiment uses a connecting member 8 to further improve the integrity of the structure. This embodiment further explains the structure.

[0041] In this embodiment, Figure 5 The first pin plate 301 and the second pin plate 302 are fixedly connected by an oblique connecting plate 303, and the two ends of the connecting plate 303 are respectively fixed to the inner surfaces of the first pin plate 301 and the second pin plate 302, so as to avoid the right-angle structure problem; the connecting plate 303 and the bevel rib 403 are arranged in parallel and are both provided with corresponding through holes, so as to facilitate the insertion and fixing of the connecting member 8, and the connecting member 8 passes through the through hole to fix the connecting plate 303 and the bevel rib 403 into a whole, and the connecting member 8 is a bolt kit, and the connecting member 8 is distributed on the splicing surface 101 of the first stone plate 1 and the second stone plate 2 In the reserved gap between the two, in order to facilitate installation, the connecting piece 8 is passed from the outside to the inside, and its bolt head is located in the reserved gap and abuts against the connecting plate 303, while its screw extends inwardly out of the gap range and abuts against the bevel rib 403 through the nut, so that the corner fixing piece 4 and the reinforcing rib plate are fixedly connected as a whole, which greatly enhances the overall rigidity of the structure, can evenly disperse the stress at the joints and connections, reduce structural damage due to uneven loading, help resist deformation caused by external forces (such as wind pressure, etc.), and ensure that the structure remains stable and safe during long-term use.
