Description

Technical Field

[0001] The invention relates to a green building structure, and in particular to a composite honeycomb panel and a panel overlap structure. Background Art

[0002] With the advancement of technology and the application of new materials, the performance and requirements of building structures are gradually improving. Decorative and functional panels have begun to be used in green buildings in large quantities, and their panels usually require materials with better structural performance and lighter weight. Flexibility and weather resistance of assembly are required, and panels are overlapped to serve as building curtain walls, exterior walls, and interior partitions or decorative panels. How to create panels with diverse functions based on existing panels and combining low-carbon, high-permeability materials is the direction that current research and development needs to study. With the development of the style of the panels, the physical properties of the panels have gradually increased, and the functional panels composed of panels with various functions also have different physical properties, so that the functional panels need to ensure that they can maintain the expected functional form after installation after being overlapped.

[0003] In order to meet the recycling needs of green buildings, lightweight functional panels are usually installed in a detachable manner. Based on the installation benchmark and stability, some functional panels are mainly fixed by bolts, but this method does not meet the adjustment needs after the functional panels are installed. The current overlap method is to lock the entire contact surface through the connector, and then install the connector on the keel through the slider to complete the fixation and adjustment needs. However, although this overlap method can meet certain adjustment needs, its complexity and time-consuming characteristics significantly slow down the overall assembly speed of green buildings, and also increase the failure points of the structure. When applied on a large scale, it is time-consuming and laborious to accurately fit and adjust the contact surface. Therefore, how to optimize the overlap method of the functional panel, reduce the structural failure points, and speed up the assembly speed is worthy of study for green buildings.

[0012] Preferably, the right fold includes a first fold and a second fold, and the left fold includes a third fold and a fourth fold; the first fold and the third fold are respectively arranged on the edges of both sides of the functional board. The third fold is parallel to the first fold, and the top of the third fold has a height difference with the top of the first fold, the second fold is placed on the top of the first fold, and the fourth fold is placed on the top of the second fold; when the functional board is spliced, the third fold fits the outer wall of the first fold, and the lower surface of the fourth fold fits the upper surface of the second fold; and the fourth fold and the second fold are used to extend into the first buckle.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship, movement status, etc. in a certain specific working state. If the specific posture changes, the directional indication will also change accordingly. In the present invention, unless otherwise clearly specified and limited, the term "connection" and the like should be understood in a broad sense. For example, "connection" can be an electrical signal connection or a signal connection; it can also be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] If there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] At present, the overlap of the panels is mainly coordinated by hangers. When the existing hangers overlap the functional panels, they mainly match the functional panels through the preset notches on the hangers. Two functional panels need to be connected separately through one hanger, which makes it difficult for the functional panels to fit together. Even if some functional panels are installed by fitting first, the hangers and the two panels are locked separately; from the perspective of stability, when the two functional panels are under load, the two functional panels transfer the load to different positions of the hangers, and the load transfer path may be uneven. Moreover, the hangers and the functional panels are generally matched and locked separately through preset notches. When the functional panels are subjected to force or vibration for a long time, looseness is likely to occur. More importantly, during the installation process, the hanger position needs to correspond to the two functional panels, so that the position needs to be adjusted during installation to ensure that there will be no obvious gap between the two functional panels during installation, which may limit the load shared by the hangers. If there are several functional panels, the load dispersion effect between the functional panels may be limited. The pendant can only improve the load transfer stability by increasing the contact surface with the functional board. Specifically, the higher the mechanical requirements of the structure, the greater the contact length between the pendant and the functional board.

[0035] refer to Figure 2 and Figure 3 As shown, based on the above embodiment, another embodiment of the present invention is a plate overlap structure; comprising a hooking hanger 1 and two or more functional plate bodies 2, wherein the functional plate body 2 can be a honeycomb composite plate, an aluminum plate, an iron plate, a titanium plate, a zinc plate, a stainless steel plate or other existing metal plates; the above-mentioned hooking hanger 1 is used to connect the functional plate body 2, and the above-mentioned functional plate body 2 is respectively provided with a right folding edge 3 and a left folding edge 4 on both sides, wherein the right folding edge 3 and the left folding edge 4 on both sides of the functional plate body 1 can be realized by folding; the overlap between adjacent functional plate bodies 2 is realized by utilizing the height difference formed by the right folding edge 3 and the left folding edge 4, and the top of the right folding edge 3 and the top of the left folding edge 4 are stacked on each other at different heights; the left folding edge 4 is overlapped on the right folding edge 3, so that the contact surface of the left folding edge 4 and the right folding edge 3 forms the splicing reference of the two functional plate bodies 1; the contact surface of the left folding edge 4 is butted with the contact surface of the right folding edge 3, and the contact area can be ensured by aligning the planes, thereby improving the stability of the combination.

[0036] There is a height difference between the top of the right folded edge 3 and the top of the left folded edge 4. On the one hand, the height difference can facilitate the connection orientation of the functional board body 2, thereby ensuring that the functional board body 2 can be installed in the specified position. On the other hand, by controlling the height difference within a constant range, when two adjacent functional board bodies 2 are overlapped; the right folded edge 3 and the left folded edge 4 are overlapped with each other, thereby ensuring that the outer wall of the right folded edge 3 and the outer wall of the left folded edge 4 fit each other; it is beneficial to position the functional board body 2, making it easier to maintain a high fit at the bottom of the functional board body 2.

[0037] The length of the hooking hanger 1 is shorter than the length of the rail, wherein the length of the hooking hanger 1 can be relatively short, and compared with the existing locking member, it is usually not necessary to be equal to the length of the rail. The hooking hanger 1 includes an upper connecting member 5 and a lower connecting member 6, and the lower connecting member 6 is installed on the side wall of the upper connecting member 5.

[0038] The lower connecting member 6 is installed on the side wall of the upper connecting member 5; the lower end of the lower connecting member 6 extends to below the upper connecting member 5; and the lower end of the lower connecting member 6 is bent to form a first buckle 7 that matches the rail, and the first buckle 7 is used to insert into the rail.

[0039] Exemplarily, the lower connecting member 6 is mainly used to connect the rail, and the first buckle 7 is inserted from the end of the rail and slides to a fixed position; the contact area between the first buckle 7 and the rail serves as a separate supporting area.

[0040] For example, the upper connector 5 is mainly used to connect the keel 8, so that the connection between the lower connector 6 and the upper connector 5 is mainly used for load transmission; therefore, the lower connector 6 and the upper connector 5 are integrally arranged or rigidly connected. If a rigid connection is adopted, in principle, the upper connector 5 and the lower connector 6 are processed separately, and the lower connector 6 needs to be fixedly installed on the side wall of the upper connector 5, and its installation method can be bolts or welding, or it needs to meet the relevant load requirements.

[0041] Among them, the area where the first buckle 7 fixes and cooperates with the rail is the working cavity, and the above-mentioned working cavity is enclosed by the first buckle 7, the upper connecting piece 5 and the lower connecting piece 6; wherein, the above-mentioned end of the rail is placed in the working cavity, and the above-mentioned first buckle 7 has an interference fit with the rail, and the first buckle 7 cooperates with the upper connecting piece 5 to clamp the end of the rail.

[0042] By utilizing the height difference between the right folded edge 3 and the left folded edge 4 to construct a reference and form a rail, the hooking hanger 1 is inserted into the rail through the first buckle 7, and the working cavity in the first buckle 7 forms a single supporting area. One supporting area locks more than two functional panels 2 and ensures the stable fit of the two functional panels 2.

[0043] Therefore, compared with the traditional method, the method of constructing a benchmark using height difference can reduce the difficulty of calibration during assembly. While ensuring load transfer, this overlap method can use a relatively short hook hanger 1, thereby greatly reducing the consumption of structural materials, so as to ensure that the building walls and decorative surfaces formed by the overlap of the functional panels 2 are not prone to local loosening, and can avoid the loosening of a single functional panel 2 causing quality risks to the entire building wall or decorative surface.

[0044] refer to Figure 3 , Figure 4 and Figure 8As shown, based on the above embodiment, another embodiment of the present invention is that the lower end of the upper connecting member 5 is provided with a first protrusion 501, and the first protrusion 501 is used to contact the rail and form a contact point A. The first protrusion 501 makes the first protrusion 501 on the surface of the upper connecting member 5 contact the upper end of the left folded edge 4 of the rail within a limited range, and the contact area is limited by the first protrusion 501 to form a contact point A, ensuring that the first protrusion 501 forms a sufficient downward pressure effect on the rail at the contact point A.

[0045] In order for the first buckle 7 to apply a supporting force to the rail relative to the contact point A, the end of the rail extends toward the bottom of the first buckle 7 and contacts the bottom of the inner cavity of the first buckle 7 to form a contact point B. When the rail is pressed at the contact point A, the rail is extended toward the bottom of the first buckle 7 to contact the bottom of the first buckle 7 to form a contact point B relative to the contact point A, and the first protrusion 501 applies downward pressure to the upper end of the rail, and the first buckle 7 applies an upward supporting force to the rail; it is clamped by the first protrusion 501 and the first buckle 7.

[0046] Furthermore, in order to better form a supporting structure, the end of the first buckle 7 is provided with a first supporting plate 701 facing the upper connecting member 5, and a gap is reserved between the first supporting plate 701 and the bottom of the upper connecting member 5 for the rail to pass through; since the first buckle 7 is made of profile as a whole, and the first buckle 7 and the rail need to have an interference fit, the setting of the gap helps the first buckle 7 to be interactively inserted from the end of the rail.

[0047] For reference, the upper end of the first support plate 701 faces the upper connecting member 5, so that under the force state, the upper end of the first support plate 701 is used to resist the rail and form a C contact point; wherein the A contact point is placed above the B contact point, and the A contact point, the B contact point and the C contact point form a triangular lock between the hooking hanger 1 and the rail.

[0048] The contact point A is formed by the first protrusion 501 of the upper connecting member 5 contacting the upper end of the left folded edge 4 of the rail to generate a downward pressure and limit the upward movement trend of the rail.

[0049] Among them, the end of the rail contacts the inner cavity at the bottom of the first buckle 7, and the support force opposite to the downward pressure of the contact point A is applied to the rail by the contact point B, so that the rail forms an upper and lower clamping state, ensuring the vertical stability of the rail and preventing it from sliding downward or loosening.

[0050] Among them, the upper end of the first support plate 701 contacts the rail to form a C contact point, which improves the stability of the rail in the horizontal direction. The reserved gap allows the rail to have a certain amount of room for movement during the insertion process, forming an interference fit to ensure the locking effect.

[0051] Therefore, the three contact points A, B, and C are respectively located in different directions of the rail. Under the premise that the first buckle 7 and the rail adopt interference fit, clamping and restriction are performed through the mechanical relationship of triangular distribution, which can reduce the degree of freedom, ensure support and restriction on the rail in all directions, and ensure the stability of the structure.

[0052] Based on the above embodiments, reference Figure 5 As shown, another embodiment of the present invention is that the right hem 3 includes a first hem 301 and a second hem 302, and the left hem 4 includes a third hem 401 and a fourth hem 402; the first hem 301 and the third hem 401 are respectively arranged at the edges of both sides of the functional board 2. The third hem 401 is parallel to the first hem 301, and the top of the third hem 401 has a height difference with the top of the first hem 301, the second hem 302 is placed on the top of the first hem 301, and the fourth hem 402 is placed on the top of the second hem 302. The first hem 301 contacts the third hem 401, thereby effectively limiting the displacement of the functional board in the lateral direction; the second hem 302 contacts the fourth hem 402, thereby effectively limiting the displacement of the functional board in the vertical direction, and at the same time, the second hem 302 and the fourth hem 402 can be stacked to increase the contact area and friction.

[0053] For example, when the functional plate 2 is spliced, the third folded edge 401 is attached to the outer wall of the first folded edge 301, and the lower surface of the fourth folded edge 402 is attached to the upper surface of the second folded edge 302; and the fourth folded edge 402 and the second folded edge 302 are used to extend into the first buckle 7. By partially extending the fourth folded edge 402 and the second folded edge 302 into the first buckle 7, the clamping force and buckling force of the buckle further enhance the locking effect, ensuring that it is not easy to loosen under the action of external force.

[0054] Further, in order to contact the bottom of the inner cavity of the first buckle 7 with the track, a fifth folded edge 303 is provided at the end of the second folded edge 302, and the fifth folded edge 303 extends toward the bottom of the first buckle 7 and contacts the bottom of the inner cavity of the first buckle 7, wherein the setting range of the height of the fifth folded edge 303 is:

[0055] H4-H2-H3+1mm≥H1≥H4-H2-H3;

[0056] In the formula, H1 is the height of the fifth folded edge 303 , H2 is the thickness of the second folded edge 302 , H3 is the thickness of the fourth folded edge 402 , and H4 is the fitting height from the bottom of the inner cavity of the first buckle 7 to the upper connector 5 .

[0057] It is worth noting that in order to reduce the risk of shaking after the right fold 3 and the left fold 4 come into contact, a chamfer can be set at the junction of the second fold 302 and the fifth fold 303, and the lower end contour of the fourth fold 402 is adapted to the chamfer contour, so as to form a better friction constraint, thereby reducing the risk of shaking of the right fold 3 and the left fold 4.

[0058] refer to Figure 2 , Figure 6 and Figure 7 As shown, based on the above embodiment, in order to better form the functional surface of the functional board body 1, another embodiment of the present invention is that it also includes a keel 8, and the upper end of the upper connector 5 is provided with a second buckle 502, and the second buckle 502 is connected to the keel 8; the keel 8 is directly connected through the upper connector 5, and the upper connector 5 transfers the load of the functional board body 1 and the hooking hanger 1 to the keel 8. Among them, the lower end of the keel 8 is provided with a socket 801 adapted to the second buckle 502, and the upper end of the keel 8 is externally connected to the carrier, so that the hooking hanger 1 locks the functional board body 2 on the keel 8 and transfers the load.

[0059] For reference, the second buckles 502 are generally two in number, and two support points are generated on the keel 8 by cooperating with the socket 801. The two support points can ensure that the keel 8 and the hooking hanger 1 are in a relatively stable posture for load transfer. During installation, perform the following steps:

[0060] S100, determining the type of the functional board 2, and establishing redundant areas on the side walls of the functional board 2, respectively, wherein the redundant areas are used to set the right folding edge 3 or the left folding edge 4;

[0061] S200, establish a reference relationship between the right fold 3 and the left fold 4, align the bottom of the functional board 2 with the reference plane, configure the thickness and height of the right fold 3, and set the height of the left fold 4 to be greater than the thickness of the right fold 3.

[0062] S300, determine the installation direction of the right fold edge 3 and the left fold edge 4, and splice the two functional panels 2 along the alignment position of the right fold edge 3 and the left fold edge 4, so that the third fold edge 401 and the first fold edge 301 are in contact with each other, and the fourth fold edge 402 and the second fold edge 302 are in contact with each other to form a track.

[0063] S400, insert the first buckle 7 of the hooking hanger 1 from the end of the rail and slide it to a fixed position, determine that the first buckle 7 and the rail are in an interference fit, check whether the contact points A, B and C are stably formed, and ensure that the three contact points apply downward pressure, lifting force and lateral support force to the rail respectively.

[0064] S500, connecting the upper connecting piece 5 of the hooking hanging piece 1 to the keel 8, and inserting the second buckle 502 into the socket 801 of the keel 8 for fixing.

[0065] A further setting method is that the keel 8 is set in a horizontal direction, and N functional panels 2 are set in the horizontal direction, where N is an integer and N is greater than or equal to 2; the right folded edge 3 and the left folded edge 4 are mutually conflicted in the horizontal direction and form N-1 rails, and the number of the hooking hangers 1 is the same as the rails, and N-1 hooking hangers 1 are connected by one keel 8.

[0066] Among them, the rails formed by N functional panels 2 are parallel to each other, and all the rails intersect with the forward projection of the keel 8; each rail is locked by a hook hanger 1 and connected to the keel 8, so that one keel 8 can support multiple hook hangers 1 and corresponding functional panels 2 in the horizontal direction.

[0067] For reference, in order to make the horizontal functional panel 2 more stable, the left and right ends of the N functional panel bodies 2 are connected to each other, and the front and rear ends of the functional panel bodies 2 are aligned with each other in principle. A functional surface is formed by installing multiple functional panel bodies 2 in parallel, and the deformation resistance and bearing capacity of the functional surface are relatively stable.

[0068] A further setting method is that the N above-mentioned functional plate bodies 2 are mutually in conflict with each other in the horizontal direction to form a load unit, and the number of the above-mentioned load units is more than two, and the above-mentioned load units are mutually fitted in the vertical direction; wherein, the rails of two adjacent load units correspond to each other, and the N functional plate bodies 2 are formed into a load unit, and the multiple load units are mutually fitted in the vertical direction, and each intersection is fixed and locked with a hook hanger 1.

[0069] In order to ensure that one hook hanger 1 can simultaneously lock four functional panels 2 while ensuring a stronger load bearing capacity, the above-mentioned hook hanger 1 is fixed at the intersection of the rails of two load units, and one hook hanger 1 simultaneously locks the four functional panels 2 and transmits the load.

[0070] A further setting method is that the above-mentioned keel 8 is L-shaped, the above-mentioned socket 801 is arranged on the side of the keel 8, and the upper surface of the above-mentioned keel 8 is provided with a mounting hole, and the mounting hole is connected to a connecting rod. Among them, the keel 8 is L-shaped, which can better lightweight structure, and the socket is arranged on the side of the keel 8, and its socket 801 and the second buckle 502 adopt interference fit, in order to facilitate the second buckle 502 to be inserted into the socket 801. The thickness of the above-mentioned second buckle 502 can be relatively thin, so that the socket 801 and the second buckle 502 can be inserted vertically. Among them, the mounting hole is used for the external connecting rod, and after the connecting rod is inserted into the mounting hole, it is fastened to the mounting hole by bolts. Its connecting rod can be externally connected to a carrier, and the overall load of the structure is carried by the carrier.

[0071] Considering the diversity of the functional board body 1, when the functional board body 1 is a honeycomb composite board, in order to better meet different functional requirements, the current honeycomb aluminum panel is coated by roller coating process, so that the coating is uniform and a certain adhesion is guaranteed. If necessary, the surface can be treated with fluorocarbon resin with strong corrosion resistance to obtain stronger corrosion resistance and scratch resistance. Generally speaking, the honeycomb aluminum panel has a certain sound insulation function because each honeycomb in the honeycomb core is closed, thus blocking the air circulation and effectively blocking the propagation of air. However, there is still a lot of room for improvement in the current honeycomb panel. From the perspective of sound insulation, the hollow honeycomb structure will cause sound waves to reflect internally, so the sound insulation effect has a clear upper limit. In terms of mechanical properties, although the honeycomb structure can obtain good mechanical properties, the overall stability of the structure may be affected when it is impacted or subjected to heavy loads for a long time. Some honeycomb panels use aluminum materials that are flame retardant, but the air layer in the honeycomb structure may also easily form a fire diffusion channel in the event of a fire; and the structure itself usually does not support light penetration, so in the design that requires natural light illumination, the honeycomb aluminum panel cannot be used.

[0072] refer to Figure 1 As shown, one embodiment of the present invention is a honeycomb composite panel, comprising a bottom plate 11, a top plate 22 and a honeycomb core 33, wherein the honeycomb core 33 is arranged between the bottom plate 11 and the top plate 22. Functional fillers are arranged in the core of the honeycomb core 33, and a matrix material is arranged between the honeycomb core and the bottom plate and the top plate. The matrix material can be a fiber material or a light-transmitting material. By evenly arranging the honeycomb core and the matrix material between the top plate and the bottom plate, the stability and durability of the bottom plate and the top plate can be further improved. This allows more functional materials to be selected for the bottom plate and the top plate, for example, the bottom plate and the top plate can be polycarbonate, polymethyl methacrylate, or other high-performance light-transmitting composite materials.

[0073] In order to adapt the honeycomb composite panel to different environments and functional requirements, the honeycomb core includes any one of thermoplastic honeycomb core, thermosetting honeycomb core, aluminum honeycomb core, paper honeycomb core, aramid honeycomb core, carbon fiber reinforced honeycomb core or glass fiber reinforced honeycomb core. Carbon fiber reinforced honeycomb core can be used in environments requiring extremely high structural performance and low weight, while aluminum honeycomb core can provide an environment that takes into account both light weight and high strength, such as building curtain walls or the internal structure of vehicles. Aramid honeycomb core is suitable for use in environments requiring extremely high elastic resistance and impact resistance, such as indoor partition walls.

[0074] In order to ensure that the composite board is not limited to the characteristics of structural strength and light weight, it can also provide additional functions according to specific application requirements. The functional filler includes any one of flame retardant filler, sound absorbing filler, heat insulating filler or light transmissive particle filler. The hole core in the nest core is filled with different functional fillers, such as flame retardant filler, sound absorbing filler, heat insulating filler or light transmissive particle filler, so that the corresponding material can be selected according to the needs to obtain better flame retardancy, sound absorption, heat insulation or optical properties.

[0075] For example, when filled with flame-retardant fillers, it can be used in buildings with higher fire safety standards. The filling materials in the honeycomb core material have flame-retardant properties and can burn at high temperatures, thereby minimizing the passage of the honeycomb core material, which can effectively improve the fire resistance level of building materials and increase safety.

[0076] For example, the honeycomb structure of the honeycomb core material itself blocks air circulation and has a basic sound insulation effect. After filling with sound-absorbing fillers, the fillers can absorb and reduce the sound wave energy transmitted by the honeycomb core material. Its sound-absorbing fillers are existing porous structural materials, which cause sound waves to be subjected to more friction and collision when passing through these porous materials, thereby dissipating more energy, thereby optimizing the acoustic performance of the space and reducing echoes and noise disturbances. The presence of fillers allows the honeycomb structure to not only physically block the propagation of sound waves, but also absorb sound wave energy to further reduce noise transmission.

[0077] For example, honeycomb composite panels are suitable for buildings that require high efficiency and energy saving. When filled with thermal insulation fillers, the fillers are mainly used to reduce the heat flow exchange inside and outside the building, helping to save energy and control the indoor ambient temperature.

[0078] For example, when the bottom plate and the top plate are transparent, they can be filled with translucent particles. The translucent particles allow the light entering the honeycomb panel to be converged or scattered to meet different light introduction requirements. When the honeycomb panel is used as a top light skylight or a wall in a specific area, it not only provides structural support but also creates a more comfortable and energy-saving light environment.
