Description

Technical Field

[0001] This utility model relates to a prefabricated composite thermal insulation wall panel and its installation structure, belonging to the technical field of building thermal insulation structure. Background Technology

[0002] Prefabricated insulated wall panels are prefabricated in the factory and then transported to the construction site for installation on the building frame. The current wall panels have the following problems during installation and use: (1) During the installation and use of the wall panels, they will be affected by various stresses, such as wind pressure, which will cause the inner and outer panels to bear shear and torsional forces. Under the action of these forces, the groove part, as the main stress point, is prone to loosening between the insulation board and the pouring layer or even wall panel breakage, which will damage the overall building structure. (2) When the wall panels are tightened and fixed to the building frame by bolt and nut assembly, a large pressure will be generated on the wall panels, which will easily cause the wall panels to deform and affect the overall performance and appearance of the wall panels. (3) When the wall panels are installed in the building, the outer panel usually needs to be cantilevered by one-third or one-half. The inner panel of the existing wall panels only has a steel wire mesh, which has certain limitations in terms of stress and reinforcement capacity. (4) The insulation boards used in the existing wall panels have low strength and poor compressive strength, which also exacerbates the instability of the building structure. (5) In building construction, the stability of the connection between the wall panel and the building frame is crucial. Currently, there are few connection points between the wall panel and the building frame, and the cooperative stress-bearing capacity between the wall panel and the building frame is limited when facing complex stress and vibration. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model provides a prefabricated composite thermal insulation wall panel and its installation structure. The wall panel itself has high strength, and the wall panel is tightly integrated with the building frame to form a stable whole, which can withstand forces from all directions in a comprehensive and balanced manner.

[0004] This utility model achieves the above objectives by adopting the following technical solutions:

[0005] The prefabricated composite insulation wall panel includes a first casting layer, an insulation board, and a second casting layer arranged sequentially. The first casting layer is embedded with a first steel mesh, and the second casting layer is embedded with a wire mesh and a second steel mesh. The distance between the second steel mesh and the insulation board is greater than the distance between the wire mesh and the insulation board.

[0006] The surfaces of the first and second casting layers near the top and bottom edges are provided with grooves. The thickness of the insulation board corresponding to the groove is less than the thickness of the insulation board in other parts, so that the thickness of the first and second casting layers corresponding to the groove is greater than the thickness of the casting layers in other parts.

[0007] The prefabricated composite insulation wall panel corresponding to the groove has a sleeve embedded in it. The axis of the sleeve is perpendicular to the wall surface of the prefabricated composite insulation wall panel. End plates are fixedly fitted at both ends of the sleeve. The surface of the end plates is flush with the surface of the first and second casting layers.

[0008] Optionally, the first casting layer and the second casting layer may have one groove on the upper part and two grooves on the lower part, or the first casting layer and the second casting layer may have two grooves on the upper part and two grooves on the lower part, or the first casting layer and the second casting layer may have two grooves on the upper part and one groove on the lower part.

[0009] Optionally, the prefabricated composite insulation wall panel provided by this utility model also includes a plurality of steel bars embedded in the prefabricated composite insulation wall panel. The steel bars penetrate the insulation panel, and the ends of the steel bars are connected to the corresponding first steel mesh or second steel mesh.

[0010] Optionally, the prefabricated composite insulation wall panel has steel reinforcement components embedded in its upper, lower, and middle parts.

[0011] Optionally, the reinforcing steel member is an L-shaped steel bar or a C-shaped steel bar.

[0012] Specifically, the L-shaped steel bar is composed of vertically arranged horizontal and vertical segments. The vertical segments of a portion of the L-shaped steel bar are located in the first casting layer and connected to the first steel mesh, while the horizontal segments extend through the insulation board and into the second casting layer. The vertical segments of another portion of the L-shaped steel bar are located in the second casting layer and connected to the second steel mesh, while the horizontal segments extend through the insulation board and into the first casting layer.

[0013] The C-shaped steel bar is composed of horizontal bars and vertical bars connected to its two ends, with the two vertical bars located in the first and second pouring layers, respectively.

[0014] Optionally, multiple reinforcing ribs are spaced apart inside the insulation board, with the ends of the reinforcing ribs protruding from the insulation board, and the wire mesh is connected to the corresponding ends of the reinforcing ribs.

[0015] Optionally, the first and second pouring layers are formed by pouring and curing building slurry, wherein the building slurry is lightweight concrete or foamed cement, and the foamed cement contains vitrified microspheres or polystyrene particles.

[0016] The insulation board is any one of SEPS board, EPS board, XPS board, SXPS board, rock wool board, or glass wool board.

[0017] The installation structure of the prefabricated composite thermal insulation wall panel provided by this utility model includes a back plate, an angle steel, and a bolt and nut assembly; the angle steel is composed of a first side plate and a second side plate arranged vertically, and the bolts of the bolt and nut assembly pass through the back plate, the sleeve inside the prefabricated composite thermal insulation wall panel, and the first side plate of the angle steel in sequence from the groove part; the second side plate of the angle steel is connected to the ground, the steel beam of the building frame, or the concrete beam of the building frame.

[0018] The beneficial effects of this application include, but are not limited to:

[0019] The prefabricated composite thermal insulation wall panel and its installation structure provided by this utility model (1) adjust the thickness of the thermal insulation board and the casting layer at the location of the installation structure. Specifically, the thickness of the thermal insulation board in the groove is reduced, and the thickness of the casting layer of the inner leaf plate and the outer leaf plate is increased accordingly. This effectively enhances the strength of the wall panel in the groove, enabling the groove to withstand greater external forces, effectively dispersing stress, and avoiding point damage caused by excessive local stress. This improves the stability and durability of the entire building structure, enabling the building structure to cope with various complex stress environments. (2) A sleeve is pre-embedded in the wall panel in the groove. The sleeve has high strength and good compressive strength. After the sleeve is added in the wall panel, the back plate and angle steel will directly apply force to the sleeve, effectively preventing the wall panel from deforming due to compression. This ensures that the wall panel always maintains its original shape and structural integrity, laying a solid foundation for the smooth progress of subsequent construction procedures and the long-term stable use of the wall panel, and effectively ensuring the quality and safety of the building project. (3) A wire mesh and a second steel mesh are installed in the inner leaf plate, which improves the strength of the inner leaf plate. It can cooperate with the first steel mesh in the outer leaf plate to constrain and reinforce the wall panel from both inside and outside. This allows the wall panel to distribute stress more evenly when facing external impact, greatly improving the overall strength of the inner leaf plate and effectively reducing the probability of cracks and deformation in the wall panel. This provides a more solid and reliable guarantee for the stability and safety of the building structure, laying a solid foundation for building a high-quality and long-life building. (4) The two ends of the steel reinforcement are connected to the steel mesh in the inner leaf plate and the outer leaf plate. The steel reinforcement and the steel mesh intertwine to form a stable load-bearing frame, which enhances the mechanical properties of the wall panel in all aspects and improves the wall panel's resistance to wind pressure and various stress conditions, ensuring the safety and stability of the building structure. When wind pressure acts on the wall panel, it can effectively disperse the stress generated by the wind pressure and prevent the wall panel from deforming or breaking due to excessive pressure. (5) This utility model increases the number of connection points between the wall panel and the building frame to three or four. Specifically, it can adopt several layouts such as two-up-one-down, one-up-two-up, and two-up-two-down. While fixing the position of the wall panel in the upper, lower, left, and right directions, it also prevents the wall panel from rotating, so that the wall panel and the building frame are tightly integrated into a more stable whole. It can withstand forces from all directions in an all-round and balanced manner, reduce the risk of wall panel displacement and falling off, and improve the seismic performance and stability of the building structure.

Detailed Implementation

[0029] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0030] It should be noted that many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1-4 As shown, the prefabricated composite thermal insulation wall panel provided by this utility model includes a first casting layer 100, an insulation board 200 and a second casting layer 300 arranged sequentially. The first casting layer 100 is embedded with a first steel mesh 110, and the second casting layer 300 is embedded with a wire mesh 310 and a second steel mesh 320. The distance between the second steel mesh 320 and the insulation board 200 is greater than the distance between the wire mesh 310 and the insulation board 200.

[0032] Typically, when the first pouring layer 100 and the second pouring layer 300 are located on the outer wall side and the inner wall side of the insulation board 200, respectively, the first pouring layer 100 and the second pouring layer 300 can also be referred to as the outer sheet and the inner sheet.

[0033] like Figure 2 As shown, grooves 400 are provided on the surfaces of the first casting layer 100 and the second casting layer 300 near the top edge and the bottom edge, respectively. The thickness of the insulation board corresponding to the groove 400 is less than the thickness of the insulation board in other parts, so that the thickness of the first casting layer 100 and the second casting layer 300 corresponding to the groove 400 is greater than the thickness of the casting layer in other parts.

[0034] A sleeve 500 is pre-embedded in the prefabricated composite insulation wall panel corresponding to the groove 400. The axis of the sleeve 500 is perpendicular to the wall surface of the prefabricated composite insulation wall panel. End plates 510 are fixedly sleeved at both ends of the sleeve 500. The surface of the end plate 510 is flush with the surface of the first casting layer 100 and the second casting layer 300.

[0035] like Figure 5 and Figure 6 , Figure 7 As shown, the installation structure of the prefabricated composite thermal insulation wall panel provided by this utility model includes a back plate 610, an angle steel 620, and a bolt and nut assembly 630.

[0036] The angle steel 620 is composed of a vertically arranged first side plate 621 and a second side plate 622. The bolts 631 of the bolt and nut assembly 630 pass sequentially from the groove 400 through the back plate 610, the sleeve 500 inside the prefabricated composite insulation wall panel, and the first side plate 621 of the angle steel 620. The second side plate 622 of the angle steel 620 is connected to the ground 1, the steel beam 2 of the building frame, or the concrete beam 3 of the building frame.

[0037] like Figure 6As shown in (a), the steel beam 2 of the building frame is fixed to the second side plate 622 by welding; as Figure 6 As shown in (b), the ground, the building frame concrete beam 3 and the second side plate 622 are connected by expansion bolts 640.

[0038] Furthermore, a washer 650 is usually provided between the head of the bolt 631 and the back plate 610, and between the nut 632 and the first side plate 621 of the angle steel 620, to prevent loosening.

[0039] During installation, the wall panel provided by this utility model is erected. The back plate 610 and one of the washers are installed on the bolts 631 of the bolt and nut assembly 630. Then, the bolts are passed through the sleeves 500 on the prefabricated composite insulation wall panel. Next, the first side plate 621 of the angle steel 620 and the other washer are installed on the bolts. Finally, the nuts 632 are tightened on the bolts, thus assembling the prefabricated composite insulation wall panel with the installation structure. Then, the second side plate 622 of the angle steel 620 is connected to the ground or the concrete beams or steel beams of the building frame. The groove 400 is used to reserve installation positions for the back plate 610 and the first side plate 621 of the angle steel 620, preventing excessive height differences between the back plate 610, the first side plate 621 of the angle steel 620, and the wall surface, facilitating later mortar leveling of the wall surface.

[0040] Firstly, during the installation and use of a building, wall panels are subject to various stresses, such as wind pressure. This causes the inner and outer panels to bear shear and torsional forces. Under these forces, the grooved areas, as the main stress points, are prone to loosening between the insulation board and the pouring layer, or even wall panel breakage, leading to damage to the overall building structure. For example, in traditional wall panels, the thickness of the inner and outer panels is generally around 5cm. If grooves are added, the thickness will be reduced accordingly. After the bolts and nuts are tightened through the wall panel, it can easily cause damage.

[0041] To address this issue, this invention adjusts the thickness of the insulation board and cast-in-place layer at the location of the installation structure. Specifically, the thickness of the insulation board in the groove area is reduced, while the thickness of the cast-in-place layer of the inner and outer leaf plates is correspondingly increased. This effectively enhances the strength of the wall panel in the stress-bearing area of ​​the groove, enabling the groove to withstand greater external forces, effectively dispersing stress, and preventing point damage caused by excessive local stress. This improves the stability and durability of the entire building structure, allowing it to cope with various complex stress environments. Typically, adjusting the thickness of the insulation board and cast-in-place layer within a 250mm radius around the installation structure is sufficient, while the thickness of the insulation board and cast-in-place layer in other areas remains unchanged. Specifically, the width of the insulation board within a 250mm radius near the top and bottom edges can be reduced.

[0042] Secondly, after the bolt and nut assembly 630 is tightened and fixed, the back plate 610 and the angle steel 620 press the wall panel in the middle, which will generate a large pressure on the wall panel, which can easily cause the wall panel to deform and affect the overall performance and appearance of the wall panel.

[0043] To solve this problem, this invention embeds a sleeve 500 within the wall panel at the groove 400. The sleeve 500 possesses high strength and good compressive strength, and can be made of durable metal or high-performance engineering plastic, adaptable to the dimensions of the wall panel groove and bolt and nut assemblies. During embedding, ensure it is tightly integrated with the internal steel mesh and insulation board of the wall panel, and accurately positioned.

[0044] After the sleeve 500 is added inside the wall panel, the back plate 610 and the angle steel 620 will directly apply force to the sleeve 500, effectively preventing the wall panel from deforming due to compression, so that the wall panel always maintains the integrity of its original shape and structure, laying a solid foundation for the smooth progress of subsequent construction procedures and the long-term stable use of the wall panel, and effectively ensuring the quality and safety of the construction project.

[0045] Thirdly, when wall panels are installed in a building, the outer panels typically need to be cantilevered by one-third or one-half. In existing wall panels, only one wire mesh is installed inside the inner panel, which has certain limitations in terms of load-bearing capacity and reinforcement.

[0046] To address this issue, this invention incorporates a wire mesh 310 and a second reinforcing mesh 320 within the inner leaf plate. This enhances the strength of the inner leaf plate and allows it to work in conjunction with the first reinforcing mesh 110 within the outer leaf plate. This provides constraint and reinforcement to the wall panel from both internal and external directions, enabling the wall panel to distribute stress more evenly when subjected to external impacts. This significantly improves the overall strength of the inner leaf plate, effectively reducing the probability of cracks and deformation in the wall panel. This provides a more robust and reliable guarantee for the stability and safety of the building structure, laying a solid foundation for creating high-quality, long-lasting buildings.

[0047] Fourthly, the insulation boards currently used in wall panels have low strength and poor compressive strength, which exacerbates the instability of building structures.

[0048] To address this issue, the wall panel provided by this utility model further includes several steel reinforcement members embedded within the prefabricated composite insulation wall panel. These steel reinforcement members penetrate the insulation board 200, and their ends are connected to corresponding first steel mesh 110 or second steel mesh 320. Thus, the two ends of the steel reinforcement members are connected to the steel mesh within the inner and outer leaf plates, and the steel reinforcement members and steel mesh intertwine to form a stable load-bearing frame. This comprehensively enhances the mechanical properties of the wall panel, improves its resistance to wind pressure and various stress conditions, and ensures the safety and stability of the building structure. When wind pressure acts on the wall panel, it effectively disperses the stress generated by the wind pressure, preventing the wall panel from deforming or breaking due to excessive pressure.

[0049] Furthermore, this utility model has pre-embedded steel bars in key parts of the upper, lower and middle sections of the wall panel. The steel bars can be L-shaped steel bars 710 or C-shaped steel bars 720.

[0050] Specifically, the L-shaped reinforcing bar 710 consists of vertically arranged horizontal and vertical segments. A portion of the vertical segments of the L-shaped reinforcing bar 710 are located within the first cast-in-place layer 100 and welded to the first reinforcing mesh 110 or bound with steel wire; the horizontal segments pass through the insulation board 200 and extend into the second cast-in-place layer 300. Another portion of the vertical segments of the L-shaped reinforcing bar 710 are located within the second cast-in-place layer 300 and welded to the second reinforcing mesh 320 or bound with steel wire; the horizontal segments pass through the insulation board 200 and extend into the first cast-in-place layer 100. During production, the horizontal segments of the L-shaped reinforcing bar 710 can be directly inserted through the insulation board 200.

[0051] The C-shaped steel bar 720 consists of horizontal segments and vertical segments connected to its two ends. The two vertical segments are located in the first casting layer 100 and the second casting layer 300, respectively. During production, an opening is made in the insulation board 200, the C-shaped steel bar 720 is passed through the insulation board 200, and then the position of the C-shaped steel bar 720 is adjusted and connected to the first steel mesh 110 and the second steel mesh 320.

[0052] Fifthly, the stability of the connection between wall panels and the building frame is crucial during construction. Currently, there are relatively few connection points between wall panels and the building frame, resulting in limited collaborative load-bearing capacity between them when facing complex stresses and vibrations.

[0053] To solve this problem, this utility model increases the number of connection points between the wall panel and the building frame to three or four. Specifically, it can adopt several layouts such as two-on-one, one-on-two, and two-on-two. While fixing the position of the wall panel in the upper, lower, left, and right directions, it also prevents the wall panel from rotating, so that the wall panel and the building frame are tightly integrated into a more stable whole.

[0054] In the "two-upper-one-lower" layout, two grooves 400 are provided on the upper part of the first casting layer 100 and the second casting layer 300, and one groove 400 is provided on the lower part.

[0055] In the "top-bottom-two" layout, a groove 400 is provided on the upper part of the first casting layer 100 and the second casting layer 300, and two grooves 400 are provided on the lower part.

[0056] In the "two-upper-two-lower" layout, two grooves 400 are provided on the upper part of the first casting layer 100 and the second casting layer 300, and two grooves 400 are provided on the lower part.

[0057] Thus, the wall panel provided by this utility model is fixed to the building frame structure through multiple connection points, enabling it to withstand forces from all directions in a comprehensive and balanced manner, including wind force, seismic force, or accidental impact force during daily use. When these forces act on the wall panel, both the wall panel and the frame structure can effectively cooperate to resist the force, greatly reducing the risk of wall panel displacement and detachment, and improving the seismic performance and stability of the building structure.

[0058] In one specific embodiment, the insulation board adopts an existing inclined-insertion rib insulation board. Specifically, multiple ribs are spaced apart inside the insulation board, with the ends of the ribs protruding from the insulation board. The wire mesh is located in the inner sheet and welded and fixed to the ends of the inclined-insertion ribs.

[0059] It should be noted that, in order to maintain the required distance between the first steel mesh 110, the second steel mesh 320 and the insulation board 200, it is usually necessary to set up positioning connectors to connect the first steel mesh 110, the second steel mesh 320 and the insulation board 200. The specific connection method can adopt the structure in the prior art. For example, a pad can be set between the first steel mesh 110, the second steel mesh 320 and the insulation board 200, or the connector disclosed in the patent application with application number 2024213823684 entitled "Connector and Prefabricated Composite Self-Insulating Wall Panel Based Thereon" can be used.

[0060] When the wall panel provided by this utility model is prefabricated in the factory, (1) the first steel mesh 110 and the second steel mesh 320 are fixed on the outer wall side and the inner wall side of the insulation board 200, respectively; (2) the sleeve 500 is tied or welded at the corresponding position, and the steel bars are passed through the insulation board 200 and tied to the first steel mesh 110 and / or the second steel mesh 320; (3) the first casting layer 100 and the second casting layer 300 are poured on both sides of the insulation board 200 using a mold, and the end plate 510 on the sleeve 500 should abut against the mold. After demolding, curing is carried out to produce the wall panel provided by this utility model. It is understood that the mold should be provided with a corresponding groove forming structure at the corresponding groove 400 position.

[0061] Typically, the first pouring layer 100 and the second pouring layer 300 are formed on the surface of the insulation board by pouring and curing building slurry. The building slurry uses conventional raw materials in existing technology, such as lightweight concrete or foamed cement. The foamed cement contains vitrified microspheres or polystyrene particles.

[0062] The insulation board 200 can be made of any one of the following: SEPS board, EPS board, XPS board, SXPS board, rock wool board, or glass wool board.

[0063] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0064] In this utility model, unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0065] Any aspects of this utility model not described in detail are known to those skilled in the art.
