[0001] The present invention relates to the technical field of building engineering, and in particular to a connection node of a building facade aluminum decorative insulation integrated panel and an installation method thereof. Background Art

[0002] With the improvement of living standards and the increasing requirements for green construction, metal facades are becoming more and more popular. However, in order to prevent deformation, metal facades such as aluminum facades need to increase thickness, which is expensive and difficult to process on site. At present, many existing technologies have solved these problems, achieving true aluminum plates without deformation, fast batch production and delivery, easier and more convenient installation, more harmonious on-site coordination, and more environmentally friendly and economical. However, in the current high-rise building construction process, the connection method of the facade aluminum decorative insulation integrated panel is still relatively complicated, and the following problems are prone to occur during the installation and use of metal insulation integrated panels:

[0003] (1) There are many fasteners, which need to be installed on site, and installation omissions are prone to occur;

[0004] (2) After the fasteners are installed, they are prone to collision and deformation during transportation and installation, and it is difficult to control the vertical flatness;

[0005] (3) Metal clips and metal expansion bolts are used, which are prone to severe rust and even fall off after long-term use;

[0006] (4) The installation position of each metal insulation integrated panel needs to be adjusted to ensure that the seams are neat, which reduces the construction speed. Summary of the invention

[0007] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to propose a connection node and an installation method of a building facade aluminum plate decorative insulation integrated panel, so that the facade aluminum plate decorative insulation integrated panel can be easily transported, and is more convenient to install and more durable in high-rise building applications.

[0008] To achieve this object, the present invention adopts the following technical solutions:

[0009] The present invention provides a connection node for a building exterior facade aluminum decorative insulation integrated panel, comprising a base wall and an insulation panel, wherein the insulation panel comprises an aluminum panel frame, and an insulation rock wool layer and a cement-based roll layer are arranged in the aluminum panel frame; a mortise and tenon portion is arranged at one end of the insulation panel, and a rivet portion cooperating with the mortise and tenon portion is arranged at the other end, and the mortise and tenon portions and the rivet portions of the two insulation panels cooperate to form an anchor groove, and also include an anchor member cooperating with the anchor groove, when connected, the insulation panel is bonded to the base wall, and the anchor member is anchored into the base wall through the anchor groove.

[0010] In order to fix the insulation board on the base wall, a smoothing layer matching with the insulation board is arranged on the base wall, and a plurality of bonding points are evenly arranged on the side of the insulation board close to the smoothing layer. During installation, the insulation board is bonded to the base wall through the bonding points. Preferably, an auxiliary anchor matching with the anchor is also included, and both the anchor and the auxiliary anchor are plastic expansion bolts. The anchor passes through the mortise and tenon joint and is anchored into the base wall, and the auxiliary anchor passes through one end of the riveted joint and is anchored into the base wall.

[0011] Furthermore, in order to ensure waterproof performance, after the anchor is anchored into the base wall, a silicone weather-resistant sealant matching the anchor is arranged in the anchor groove.

[0012] A method for installing a connection node of an aluminum decorative thermal insulation integrated panel on a building facade, which is used to install the connection node of the aluminum decorative thermal insulation integrated panel on the facade as described above, and comprises the following steps: S00: acceptance treatment of the base layer, before construction, the base layer wall is inspected and accepted according to relevant regulations, and the surface of the base layer wall is flattened; S10: measurement and laying out, the measurement and laying out shall be carried out according to the external characteristics and features of the building, and the accuracy of horizontality and verticality shall be measured in combination with the construction drawing design; S20: applying special bonding mortar, and the use area of ​​the bonding mortar is determined according to the size of the thermal insulation decorative panel and the height of the building; preferably, in step S20, when the thermal insulation panel is coated with bonding mortar, the circular bonding points evenly distributed on the thermal insulation panel are circular, and the thermal insulation panel should be fully bonded when the length or width is less than 00mm, and the bonding area shall be not less than 50% within 50 meters of the building main body height, and the bonding area shall be not less than 60% when the building main body height is 50-00 meters; S30: aluminum The board decoration and thermal insulation integrated board is installed, and the bonding mortar is applied to the bonding points of the thermal insulation board. After the thermal insulation board is coated with the bonding mortar, the board should be immediately flattened on the base wall and slid into place; S40: Install the anchor, pass the anchor from the anchor groove through the mortise and tenon joint and anchor it into the base wall, and the auxiliary anchor passes through one end of the riveted part and anchors it into the base wall. Anchors and auxiliary anchors are added to the thermal insulation board with an area greater than 0.3 m2; preferably, in step S40, when the base wall is a concrete wall, the anchor and auxiliary anchor are fixed. The effective anchoring depth of the anchor and the auxiliary anchor into the base wall is not less than 30 mm; when the base wall is an aerated concrete wall, the effective anchoring depth of the anchor and the auxiliary anchor into the base wall should not be less than 50 mm; S50: embedding the caulking material, according to the size of the gap between the anchor grooves of the insulation boards, select the insulation caulking material of appropriate thickness to fill the gap between the anchor grooves of the insulation boards; preferably, in step 50, after the caulking material is embedded in the anchor groove, the thickness of the caulking material is 4 to 6 mm lower than the board surface of the insulation board;

[0013] S60: Apply sealant, use silicone weather-resistant sealant, and use a sealing gun to apply an appropriate amount of sealant evenly in the partition joints.

[0014] The beneficial effects of the present invention are:

[0015] (1) This case makes adjustments to the connection and fixing methods of the insulation board, and uses male and female groove connections for the mortise and tenon joints and riveted joints, which is conducive to mass production of the insulation board in the factory. It uses a kit for protection to avoid collision and deformation during transportation and installation. It can be directly installed and fixed at the construction site, and the male and female grooves are installed to assemble the seams. The straightness of the board seams can be ensured without aligning the seams, which makes the construction speed faster, the installation more convenient, and the construction period shorter.

[0016] (2) The insulation board used in this case has a simple structure, saves materials, and is more environmentally friendly. It is manufactured in the factory, and only some special parts need to be processed on site. No additional fasteners are required, which reduces material waste. In terms of fixing method, only plastic expansion bolts are needed, which can be easily adjusted according to the environment during design;

[0017] (3) The entire decorative insulation integrated board structure is more durable and the anchors are not easy to fall off; because it is fixed with plastic bolts, it is more firmly fixed than traditional insulation materials and is not easy to fall off. The durability of plastic bolts is better than that of metal bolts and is more durable. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the mortise and tenon joints 22 and the riveted joints 23 can be made when the insulation board is prefabricated, and then they can be conveniently protected during transportation, and are not easily deformed, so as to ensure the vertical flatness during installation. Further, in terms of the fixing method, a smoothing layer 11 that matches the insulation board 2 is provided on the base wall 1, and a plurality of bonding points 12 are evenly provided on one side of the insulation board 2 close to the smoothing layer 11. During installation, the insulation board 2 can be bonded to the base wall 1 through the bonding points 12; the anchor 3 can be fixed by the mortise and tenon joints 22 and the riveted joints 2 3 after the formation of anchor groove 24 inserted into the base wall 1 to complete the fixation, specifically also includes the auxiliary anchor 4 with the anchor 3, the anchor 3 and the auxiliary anchor 4 are plastic expansion bolts, to increase the durability in long-term use, the anchor 3 through the mortise and tenon portion 22 after anchored into the base wall 1, the auxiliary anchor 4 through the riveted portion 23 one end anchored into the base wall 1, finally after the anchor 3 is anchored into the base wall 1, the anchor groove 24 is provided with the silicone weatherproof sealant with the anchor 3; the installation of the whole thermal insulation integrated board is completed in this alternating manner.

[0036] A method for installing connection nodes of aluminum decorative insulation integrated panels for building exterior facades, used for installing the connection nodes of aluminum decorative insulation integrated panels for exterior facades as described above, comprises the following steps: S00: acceptance treatment of the base layer, before construction, the base wall 1 is inspected and accepted according to relevant regulations, and the surface of the base wall 1 is flattened; specifically, the unevenness, hollows, scum, cracks, oil stains, etc. of the base wall 1 are treated, the door and window frames or auxiliary frames should be installed, the door and window frames and the base wall 1 should be connected to the installation thickness of the insulation board 2, and the gaps should be filled tightly in layers. When the base wall 1 is particularly dry, the surface of the base wall 1 is watered and moistened before installation;

[0037] S10: measurement and setting out, measurement and setting out shall be carried out according to the external features and characteristics of the building, and the horizontal and vertical accuracy shall be measured in combination with the construction drawing design; specifically, during the processing, the flatness error shall be no more than 10mm, and on the base wall 1 that meets the requirements after the processing, according to the relevant technical requirements of the building facade design and external wall insulation, the horizontal and vertical control lines of the external doors and windows, expansion joints, decorative joints, etc. are popped out on the wall surface of the base wall 1, and vertical reference steel wires are hung at the large corners (yang corners, yin corners) and other necessary places of the building's external wall, and horizontal lines are hung at appropriate positions on each floor to control the verticality and flatness of the insulation board 2 during the construction process;

[0038] S20: Apply special bonding mortar and determine the use area of ​​the bonding mortar according to the size of the thermal insulation decorative board and the height of the building;

[0039] S30: Aluminum plate decorative thermal insulation integrated board installation, thermal insulation board 2 bonding point 12 is smeared with adhesive mortar, after the thermal insulation board 2 is smeared with adhesive mortar, the board should be immediately flattened on the base wall 1 and slid into place; specifically, when pasting, it should be gently kneaded and evenly squeezed by hand, and it is forbidden to use force or hard objects to hit the board surface of the thermal insulation board 2 vertically on the base wall to avoid damage. In order to ensure the flatness of the board surface of the thermal insulation board 2, a ruler with a length of not less than 2.0m should be used at any time for flattening operation. Before construction, the layout diagram of the decorative thermal insulation composite is compiled according to the design size of the entire exterior wall facade of each building to achieve the purpose of saving materials and increasing construction speed;

[0040] S40: Install anchors, pass the anchor 3 through the anchor groove 24 through the mortise and tenon joint 22 and then anchor it into the base wall 1, and pass one end of the auxiliary anchor 4 through the riveted joint 23 and anchor it into the base wall 1. Add anchors 3 and auxiliary anchors 4 to the insulation board 2 with an area greater than 0.3 m2; preferably, in step S40, when the base wall 1 is a concrete wall, the effective anchoring depth of the anchor 3 and the auxiliary anchor 4 entering the base wall 1 is not less than 30 mm; when the base wall 1 is an aerated concrete wall, the effective anchoring depth of the anchor 3 and the auxiliary anchor 4 entering the base wall 1 should not be less than 50 mm; to ensure the strength of the insulation board 2 when it is fixed; operation During operation, first use a drill to drill holes with a depth of not less than 50 mm on the mortise and tenon joints 22 and rivet joints 23 of the insulation board 2 and the base wall 1 (excluding the leveling layer) at the locations where the anchor 3 and the auxiliary anchor 4 need to be installed; use a hammer to drive the expansion tubes of the anchor 3 and the auxiliary anchor 4 into the pre-drilled holes to ensure that the top lock of the expansion bolt is flush with the surface of the insulation board 2; use a pistol drill to screw the core nail into the expansion tube perpendicular to the wall of the base wall 1, drill into 2 / 3, then adjust the speed and turn it in gently, screw the plastic expansion nail cap until it is flush with the surface of the insulation board 2 or slightly sinks to the bottom to ensure that the expansion anchor bolt is effectively tightened, and it is strictly forbidden to knock it in directly;

[0041] In the implementation process of the above steps S20 to S40; in order to meet the safety requirements, the decorative insulation integrated board composed of multiple insulation boards 2, in the part subject to greater negative wind pressure, should not only consider the size of the insulation decorative board and the height of the building to determine the use area of ​​the bonding mortar, but also consider increasing the bonding area between the insulation board 2 and the base wall 1 and the number of anchors (anchors 3 and auxiliary anchors 4);

[0042] Therefore, we assume that the bonding area between the insulation board 2 and the base wall 1 is S, the number of anchors is X, and the negative wind pressure per square meter of the decorative insulation integrated board composed of multiple insulation boards 2 is P. If there is no wind pressure, the number of anchors required per square meter of insulation board 2 is X0 and the bonding area is S0, then under the negative wind pressure P, the required number of anchors X and the bonding area S can establish a simplified quantitative relationship model as follows:

[0043] ① X=X0+k×P

[0044] ② S=S0+m×P

[0045] Among them, k and m are coefficients. k is used to indicate the influence of wind pressure on the number of anchors, and m is used to indicate the influence of wind pressure on the increase of bonding area. In actual application, it needs to be adjusted according to specific engineering conditions and material properties.

[0046] Furthermore, in order to obtain the relationship between the bonding area between the insulation board 2 and the base wall 1, the number of anchors, and the negative wind pressure on the insulation board 2, the total negative wind pressure P0 of the decorative insulation integrated board is used as a function, and the number of anchors X and the bonding area S are used as variables, that is:

[0047] ③P0=f(S,X)

[0048] This functional relationship represents the negative wind pressure P0 that the decorative thermal insulation integrated board composed of multiple thermal insulation boards 2 can withstand under a given bonding area S and the number of anchors X. The basic idea is that the increase in the bonding area S and the number of anchors X can improve the ability of the decorative thermal insulation integrated board to withstand the negative wind pressure P. Based on this, further parameters are introduced: representing the tensile bonding strength T per unit bonding area (affected by the slurry during bonding and the use environment), representing the tensile strength R of a single anchor (affected by the material and size of the anchor), and representing the area A of the decorative thermal insulation integrated board composed of multiple thermal insulation boards 2. A simplified basic framework can be established to represent the relationship model between the three:

[0049]

[0050] Among them: P (unit: KN / ㎡); S (unit: ㎡); T (unit: KN / ㎡); X (unit: piece); R (unit: KN / piece); A (unit: ㎡)

[0051] According to the three formulas ①②④, we can select the insulation board 2 in a targeted manner according to the use environment, and reasonably set the bonding area between the insulation board 2 and the base wall 1, as well as the setting of appropriate anchors and their quantity. Preferably, in step S20, when the insulation board 2 is smeared with adhesive mortar, the circular bonding points 12 evenly distributed on the insulation board 2 are circular, and the insulation board 2 should be fully bonded when the length or width is less than 300mm. The bonding area is not less than 50% within the height of the main building within 50 meters, and the bonding area is not less than 60% when the main building height is 50-100 meters.

[0052] S50: embedding caulking material, according to the gap size of the anchor groove 24 between the insulation boards 2, selecting insulation caulking material of appropriate thickness to fill the gap between the anchor groove 24 between the insulation boards 2; preferably, in step 50, after the caulking material is embedded in the anchor groove 24, the thickness of the caulking material is 4 to 6 mm lower than the board surface of the insulation board 2 to ensure sealing and waterproof performance;

[0053] S60: Apply sealant, use silicone weather-resistant sealant, use a sealant gun to evenly apply a proper amount of sealant in the partition joint; specifically, (the color of the sealant should be: black or gray) and then use a flat scraper to scrape the sealant flat, the depth in the partition joint is generally 1 / 2 of the partition joint depth, and the paper tape should be pulled off after the glue is applied. The time for the paper tape to be pasted on the surface of the insulation board 2 shall not exceed 2 hours to avoid damaging the paint film on the surface of the insulation board 2. If there are other design requirements, the necessary devices such as air valves and drainage should be installed before the sealant dries, which will not be repeated here.

[0054] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
