Description

Technical Field

[0001] The present application relates to the technical field of building wall panels, and in particular to a prefabricated fireproof and heat-insulating integrated composite exterior wall panel and a construction method thereof. Background Art

[0002] Exterior wall panels, also called Horizon building exterior wall decoration integrated panels, are made of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials. They are factory-produced and on-site bonded. They are the preferred materials to meet the current energy-saving needs of housing construction and improve the insulation level of industrial and civil building exterior walls. They are also the preferred materials for energy-saving renovation of existing buildings. They are used for high-rise exterior walls, indoor shopping malls, and industrial equipment. They have low cost, good effect, corrosion resistance, and no pollution.

[0003] In the existing exterior wall panel installation process, construction workers are required to apply adhesive on one side of the exterior wall panel, and then bond the exterior wall panel to the surface of the building, and then make the adhesive in close contact with the wall by knocking. In this process, since workers need to manually apply adhesive on each exterior wall panel, on the one hand, the construction workers have a large workload, which affects the installation efficiency. On the other hand, the uneven thickness of the adhesive applied manually by workers affects the parallelism between the exterior wall panel and the wall. In the later splicing process, the gaps between multiple exterior wall panels increase, which increases the thermal bridge phenomenon. At the same time, the exterior wall panel is prone to lack of adhesive, resulting in a cavity between the exterior wall panel and the wall, which affects the connection strength between the exterior wall panel and the wall and also affects the heat exchange. Summary of the invention

[0004] In order to improve the efficiency and quality of personnel installing exterior wall panels, on the one hand, the present application provides a prefabricated fireproof and thermal insulation integrated composite exterior wall panel, which adopts the following technical solution: A prefabricated fireproof and heat-insulating integrated composite exterior wall panel, comprising an insulation board, an installation frame, fixings and a fireproof board, wherein the insulation board is made of insulation material; the installation frame is sleeved on the surrounding side of the insulation board, the end of the installation frame in contact with the wall is the fixed end, and the distance between the side of the insulation board close to the fixed end and the fixed end is greater than 0, thereby forming a pouring cavity; the installation frame is provided with a pouring port on one side away from the fixed end, and an exhaust hole is provided on the opposite side, and the pouring port and the exhaust hole are both connected to the pouring cavity; the installation frame is fixed to the wall by fixings, and at this time, the fixed end is in contact with the wall; the fireproof board is made of fireproof material, and the fireproof board is installed in the installation frame and is located on the side of the insulation board away from the fixed end.

[0005] By adopting the above technical solution, the personnel first install the frame on the wall through the fixing parts, and then pump the adhesive from the pouring port into the pouring cavity through the grouting pump, so as to reduce the steps of applying the adhesive. At the same time, when the adhesive is discharged from the exhaust hole, it means that the adhesive in the pouring cavity has completely filled the pouring cavity, ensuring that there is no cavity between the insulation board and the wall, and the fireproof performance of the exterior wall panel is increased by adding the fireproof board.

[0006] Optionally, two exhaust holes are provided, and the two exhaust holes are respectively located at two corners on one side of the installation frame where the exhaust holes are provided.

[0007] By adopting the above technical solution, when the adhesive is poured from the pouring port, the adhesive liquid level is triangular in shape during the adhesive overflow process, and the adhesive liquid level directly above the pouring port is the highest. When the exhaust hole is located directly above the pouring port, when the adhesive overflows from the pouring port, the adhesive on both sides of the exhaust hole does not contact the top wall of the pouring cavity, resulting in a cavity. In order to ensure that the adhesive in the pouring cavity completely fills the pouring cavity, two exhaust holes are provided, and the two exhaust holes are respectively located at two corners on one side of the mounting frame where the exhaust hole is opened. When the adhesive overflows from the two exhaust holes at the same time, the pouring cavity is filled with adhesive.

[0008] Optionally, the insulation board slides in the installation frame in a direction perpendicular to the surface of the insulation board, and the insulation board and the installation frame slide. A pressing rod is provided on the upper edge of the insulation board perpendicular to the surface of the insulation board. One end of the pressing rod is fixed to the insulation board, and the other end extends to the side of the fireproof board away from the insulation board.

[0009] By adopting the above technical solution, after pouring the adhesive, the construction workers push the pressing rod to squeeze the insulation board, which on the one hand makes the insulation board better bonded to the wall by the adhesive, and on the other hand creates a cavity between the insulation board and the fireproof board, thereby increasing the thermal insulation effect of the exterior wall panel.

[0010] Optionally, a push plate having the same surface as the insulation board is fixed to a surface of the insulation board away from the fixed end, and an end of the pressing rod close to the fixed end is fixed to the push plate.

[0011] By adopting the above technical solution and adding a push plate, the damage to the insulation board caused by the push rod and the end of the push rod is reduced.

[0012] Optionally, an avoidance groove is provided at a corner of the installation frame, and the fixing member passes through the avoidance groove and is fixed to the wall.

[0013] By adopting the above technical solution, it is avoided that the fixing piece passes through the installation frame and causes deformation of the installation frame.

[0014] Optionally, an insulation layer made of the same material as the insulation board is provided on the end surface of the installation frame that contacts the wall.

[0015] By adopting the above technical solution, the thermal bridge phenomenon caused by the contact between the installation frame and the wall can be reduced.

[0016] Optionally, an anti-cracking net is further included, and the anti-cracking net is detachably mounted on a side of the mounting frame away from the fixed end.

[0017] By adopting the above technical solution, workers apply an anti-cracking mortar layer and wrap the anti-cracking mesh inside it to enhance the anti-cracking effect of the wall.

[0018] Optionally, a snap-in groove for snapping in the anti-cracking net is provided on a side wall of the installation frame away from the fixed end.

[0019] By adopting the above technical solution, it is convenient for personnel to connect the anti-cracking net into the connecting groove, thereby preventing the anti-cracking net from naturally falling off the installation frame.

[0020] On the other hand, the present application also provides a construction method for a prefabricated fireproof and heat-insulating integrated composite exterior wall panel, comprising the following steps: S1. Before installing the exterior wall panels, the building surface needs to be cleaned to ensure that the work area is clean and tidy; S2.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] On the one hand, an embodiment of the present application discloses a prefabricated fireproof and thermal insulation integrated composite exterior wall panel.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A prefabricated fireproof and heat-insulating integrated composite exterior wall panel comprises an insulation board 1, an installation frame 2 and a fixing member 3. The insulation board 1 is installed in the installation frame 2. The peripheral wall of the insulation board 1 is fixed to the inner wall of the installation frame 2. The installation frame 2 is installed on the wall surface through the fixing member 3. In this application, the fixing member 3 is selected from expansion bolts. In this application, the installation frame 2 is selected from a rectangular frame. The end of the installation frame 2 that contacts the wall is set as a fixed end. When the installation frame 2 abuts against the wall surface, a cavity is left between the insulation board 1 and the wall to prevent the adhesive. The distance between the side of the insulation board 1 close to the fixed end and the fixed end is greater than 0, and is preferably selected as 10 mm in this application. The insulation board 1 and the fixed end form a pouring cavity 21; In order to omit the step of applying adhesive by personnel, a pouring port 22 is opened on one side of the installation frame 2 at one end away from the fixed end, and the pouring port 22 is connected to the pouring cavity 21. Personnel pump the adhesive from the pouring port 22 into the pouring cavity 21 through a grouting pump to fill the pouring cavity 21. In this application, the adhesive can be selected from polymer mortar, silicone sealant, epoxy resin glue, and polyurethane foam according to actual needs. In order to facilitate personnel to determine whether the adhesive in the pouring cavity 21 is completely filled, an exhaust hole 23 is opened at the end of the installation frame 2 away from the fixed end on the side opposite to the pouring port 22. When the installation frame 2 is fixed to the wall, the pouring port 22 is located below the exhaust hole 23. On the one hand, the exhaust hole 23 can reduce the excessive air pressure in the pouring cavity 21 when pouring the adhesive, causing the adhesive to overflow from the gap between the fixed end and the wall. On the other hand, personnel can judge whether the pouring cavity 21 is full by the adhesive overflowing from the exhaust hole 23. Since most of the materials of the insulation board 1 are combustible materials, when a fire occurs in the building, the insulation board 1 is easily damaged. A prefabricated fireproof and heat-insulating integrated composite exterior wall panel also includes a fireproof board 4, which is installed in the installation frame 2. The surrounding side of the fireproof board 4 is fixed to the inner wall of the installation frame 2, and the fireproof board 4 is located on the side of the insulation board 1 away from the fixed end, so as to protect the insulation board 1.

[0026] Reference Figure 1 When the adhesive is poured from the pouring port 22, the adhesive liquid level is triangular in shape during the overflow process, and the adhesive liquid level directly above the pouring port 22 is the highest. When the vent hole 23 is located directly above the pouring port 22, when the adhesive overflows from the pouring port 22, the adhesive on both sides of the vent hole 23 does not contact the top wall of the pouring cavity 21, resulting in a cavity. In order to ensure that the adhesive in the pouring cavity 21 completely fills the pouring cavity 21, two vent holes 23 are provided, and the two vent holes 23 are respectively located at two corners on one side of the mounting frame 2 where the vent hole 23 is opened. When the adhesive overflows from the two vent holes 23 at the same time, the pouring cavity 21 is filled with adhesive.

[0027] Reference Figure 1 , Figure 3 and Figure 4 In order to increase the bonding strength between the adhesive and the wall and the insulation board 1, the insulation board 1 slides on the installation frame 2 in a direction perpendicular to the board surface of the insulation board 1. In order to limit the sliding of the insulation board 1, a sliding groove 24 is opened on the inner wall of the installation frame 2, and the insulation board 1 slides in the sliding groove 24. A prefabricated fireproof and heat-insulating integrated composite exterior wall panel also includes a pressing rod 5, one end of the pressing rod 5 is fixed to the side of the insulation board 1 away from the fixed end, and the other end extends to the side of the fireproof board 4 away from the fixed end, and does not extend to the outside of the installation frame 2. A plurality of pressing rods 5 are provided, which are distributed on the surface of the insulation board 1. The ends of the plurality of pressing rods 5 away from the insulation board 1 are connected to each other by connecting rods 51, so as to facilitate personnel to push the plurality of pressing rods 5 to move at the same time. At the same time, when the insulation board 1 is moved, a cavity is formed between the insulation board 1 and the fireproof board 4, thereby further increasing the heat insulation effect.

[0028] Reference Figure 3 and Figure 4In order to reduce the damage to the material of the insulation board 1 caused by the end of the pressing rod 5 when a person pushes the pressing rod 5, a prefabricated fireproof and thermal insulation integrated composite exterior wall panel also includes a pushing plate 6, which is bonded to the side of the insulation board 1 away from the fixed end, and the end of the pressing rod 5 close to the fixed end is fixed to the pushing plate 6.

[0029] Reference Figure 1 In order to reduce the damage of the fixing member 3 to the mounting frame 2 when the fixing member 3 fixes the mounting frame 2 on the wall, the mounting frame 2 is provided with an arc-shaped avoidance groove 25 at the four corners, so as to reduce the deformation and damage of the mounting frame 2 caused by the fixing member 3 passing through the mounting frame 2. After multiple mounting frames 2 are spliced, one fixing member 3 can fix the corners of four mounting frames 2; at the same time, in order to adapt to fixing members 3 of various specifications, a rubber cushion layer 26 is fixed on the wall of the avoidance groove 25.

[0030] Reference Figure 1 , Figure 3 and Figure 4 In order to avoid the thermal bridge phenomenon caused by the contact between the installation frame 2 and the wall, the installation frame 2 is fixed with an insulation layer 7 made of the same material as the insulation board 1 on the fixed end surface.

[0031] Since the exterior wall panels are in the outdoor environment for a long time, they are prone to cracking. In order to prevent the wall from cracking in the later stage, a prefabricated fireproof and thermal insulation integrated composite exterior wall panel also includes an anti-crack mesh 8. In the present application, the anti-crack mesh 8 is selected from a fiberglass mesh. After the anti-crack mesh 8 is fixed to the installation frame 2, the personnel apply an anti-crack mortar layer and wrap the anti-crack mesh 8 therein to enhance the anti-cracking effect of the wall.

[0032] Reference Figure 1 , Figure 3 and Figure 4 In order to increase the installation efficiency of the anti-crack net 8, a plurality of snap-in grooves 27 are opened on the end surface of the installation frame 2 away from the fixed end along the circumference of the installation frame 2. The opening direction of the snap-in groove 27 is perpendicular to the frame edge of the installation frame 2. At the same time, the snap-in groove 27 is parallel to the cross-sectional area of ​​the end surface of the installation frame 2, and gradually shrinks toward the center line of the cross-section in the direction from the fixed end of the installation frame 2 to the direction away from the fixed end, so as to facilitate personnel to snap the anti-crack net 8 into the snap-in groove 27 to prevent the anti-crack net 8 from falling off the installation frame 2 naturally.

[0033] On the other hand, the present application provides a construction method of a prefabricated fireproof and heat-insulating integrated composite exterior wall panel, comprising the following steps: S1, before starting to install the exterior wall panel, it is necessary to clean the surface of the building to ensure that the working area is clean and tidy; S2. Use tools such as a level and infrared line setting instrument to pop up the position line and vertical control line of the wall panel on the building according to the construction drawings; S3.
