Description

Technical Field

[0001] This utility model relates to the field of building wall panel technology, and in particular to a prefabricated building exterior wall panel with an insulation layer. Background Technology

[0002] Prefabricated exterior wall panels are core components of industrialized buildings. They are manufactured in factories and assembled on-site, offering advantages such as rapid construction, energy conservation, environmental protection, and controllable quality. Depending on the materials, structure, and function, prefabricated exterior wall panels can be categorized into various types and are widely used in residential, commercial, and public buildings.

[0003] Existing exterior wall panels have deficiencies in thermal insulation performance, requiring the additional application of insulation layers during use. However, on-site composite insulation layers require multiple processes, severely impacting construction efficiency. Furthermore, most existing exterior wall panels are assembled by splicing, necessitating the filling of joints with adhesive strips. Over time, these adhesive strips age, affecting the seal between the panels and consequently compromising insulation performance. Therefore, a prefabricated building exterior wall panel with an integrated insulation layer is needed to address these issues. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a prefabricated building exterior wall panel with an insulation layer.

[0005] The technical solution of this utility model to achieve the above objectives is a prefabricated building exterior wall panel with an insulation layer, comprising:

[0006] The main body of the wall panel is made of lightweight concrete and is rectangular in shape. Three layers of grid-like keel are evenly spaced along the thickness direction inside the panel, and multiple short columns connect two adjacent grid-like keels.

[0007] An arc-shaped sealing groove is opened at the outer end of the upper surface of the wall panel body and is circumferentially closed along the outer edge of the upper surface of the wall panel body;

[0008] The L-shaped overlapping boss is located at the center of two adjacent sides of the wall panel body and is integrally cast with the wall panel body. Three anchoring grooves are provided on it, two of which are distributed along the length of the wall panel body and the other is distributed along the width of the wall panel body. An anchoring hole is opened at the center of the lower surface of the anchoring groove. A reinforcing boss is provided below the anchoring groove and is integrally cast with the wall panel body.

[0009] The L-shaped lap groove is located at the center of the other two adjacent sides of the wall panel body. Three boss slots are opened on its lower surface. Two of the boss slots correspond to the positions of the two reinforcing bosses along the length of the wall panel body of the L-shaped lap boss. The other boss slot corresponds to the position of the reinforcing boss along the width of the wall panel body of the L-shaped lap boss.

[0010] Thermal insulation rock wool is laminated onto the lower surface of the wall panel body, and its dimensions are the same as the length and width of the wall panel body.

[0011] The sawtooth gecko metal expansion tube is embedded in a pre-drilled hole in the wall;

[0012] Anchor bolts are inserted into the anchor groove, pass through the anchor hole and the insulating rock wool, and are threaded into the sawtooth gecko metal expansion tube.

[0013] Preferably, when multiple wall panel bodies are assembled, the L-shaped overlapping protrusions on the wall panel bodies are inserted into the L-shaped overlapping grooves on two adjacent wall panel bodies, and the arc-shaped sealing grooves are joined together to form a semi-circular groove.

[0014] Preferably, after the multiple wall panel bodies are assembled, the semi-circular groove formed by the connection of the arc-shaped sealing grooves is filled with cement mortar.

[0015] Preferably, when the L-shaped overlapping boss is inserted into the L-shaped overlapping groove on the adjacent wall panel body, the reinforcing boss is inserted into the corresponding boss slot on the adjacent wall panel body.

[0016] Preferably, the mesh-like keel on the upper and lower sides of the wall panel body is cast inside the L-shaped overlapping groove.

[0017] Preferably, the mesh-like keel in the middle of the wall panel body is cast into the L-shaped overlapping boss.

[0018] Preferably, the lower surface of the reinforcing boss is aligned with the lower surface of the wall panel body.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By using thermal insulation rock wool composite on the main body of the wall panel and presenting a standard modular design, it is easy to prefabricate and mass-produce, reduce manufacturing costs, and eliminate the need for on-site composite insulation layers, which can effectively shorten assembly time and improve construction efficiency.

[0021] 2. The use of a three-layer mesh keel design can improve the strength of the wall panel itself and reduce the risk of brittle fracture, thereby improving the durability of the wall panel.

[0022] 3. The interlocking design of L-shaped overlapping bosses and L-shaped overlapping grooves creates an interlock between adjacent wall panels, enhancing the overall structural stability and preventing the wall panels from shifting or falling off due to external forces. At the same time, it facilitates the quick connection and installation of the wall panels, reducing manual adjustment time and improving assembly efficiency.

[0023] 4. By using anchor bolts and sawtooth metal expansion tubes for fixing, the connection between the wall panel and the building structure can be made more secure, and the installation difficulty can be reduced, making the installation more efficient and faster.

[0024] 5. The arc-shaped sealing groove is connected to form a semi-circular groove, which is then filled with cement mortar to form a continuous waterproof barrier, effectively preventing rainwater penetration and improving the waterproof durability of the building's exterior walls.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a technical solution, such as Figures 1-6 As shown; a prefabricated building exterior wall panel with an insulation layer includes: a wall panel body 1, which is made of lightweight concrete and is rectangular in shape, with three layers of mesh keel 11 evenly spaced along the thickness direction inside, and multiple short columns 12 connecting two adjacent mesh keels 11; an arc-shaped sealing groove 2, which is opened at the outer end of the upper surface of the wall panel body 1 and is closed circumferentially along the outer edge of the upper surface of the wall panel body 1; the mesh keels 11 on the upper and lower sides of the wall panel body 1 are cast in the two sides of the L-shaped overlapping groove 4; the mesh keel 11 in the middle of the wall panel body 1 is cast in the L-shaped overlapping protrusion 3.

[0035] In this embodiment of the utility model, the arrangement of three layers of evenly distributed mesh keel 11 can, on the one hand, strengthen the strength of the wall panel body 1 itself, so as to ensure its strength and prevent it from breaking due to bumps during transportation or use, so that it can be assembled smoothly. On the other hand, the mesh keel 11 can also strengthen the structure of the L-shaped overlapping groove 4 and the L-shaped overlapping boss 3 respectively, so as to ensure the strength of the L-shaped overlapping groove 4 and the L-shaped overlapping boss 3, making the wall panel body 1 more firmly and stably assembled.

[0036] In this embodiment of the utility model, by utilizing the setting of the arc-shaped sealing groove 2, after the wall panel body 1 is assembled, the arc-shaped sealing grooves 2 between multiple wall panel bodies 1 can be connected, and then cement mortar 8 can be used to fill them to form a connected waterproof barrier, thereby improving the sealing performance of the splicing of the wall panel body 1.

[0037] L-shaped overlapping protrusions 3 are located at the center of two adjacent sides of the wall panel body 1 and are integrally cast with the wall panel body 1. Three anchoring grooves 31 are provided on them. Two of the anchoring grooves 31 are distributed along the length of the wall panel body 1, and the other anchoring groove 31 is distributed along the width of the wall panel body 1. An anchoring hole 32 is opened at the center of the lower surface of the anchoring groove 31. A reinforcing protrusion 33 is provided below the location of the anchoring groove 31. The reinforcing protrusion 33 is integrally cast with the wall panel body 1.

[0038] In this embodiment of the utility model, by utilizing the L-shaped overlapping boss 3, the wall panel body 1 below and on one side can be quickly spliced ​​and assembled with the wall panel body 1 during splicing, thereby reducing the difficulty of splicing between wall panel bodies 1, reducing manual adjustment time, and greatly improving assembly efficiency.

[0039] In this embodiment of the utility model, by utilizing the design of the anchoring groove 31 and the anchoring hole 32, the anchoring bolt 7 can be inserted into the anchoring hole 32 and the anchoring bolt 7 can be completely embedded in the anchoring groove 31, thereby avoiding the anchoring bolt 7 from affecting the insertion of the L-shaped overlapping boss 3 into the L-shaped overlapping groove 4, so as to ensure the fast and efficient assembly of the wall panel body 1.

[0040] In this embodiment of the utility model, the design of the reinforcing boss 33 can improve the strength of the L-shaped overlapping boss 3 at the anchoring groove 31, and avoid the lightweight concrete at this position being too thin, which would affect the anchoring strength, so as to ensure that the anchoring bolt 7 can stably anchor the wall panel body 1.

[0041] The L-shaped overlapping groove 4 is located at the center of the other two adjacent sides of the wall panel body 1. Three boss slots 41 are opened on its lower surface. Two of the boss slots 41 correspond to the positions of the two reinforcing bosses 33 along the length of the L-shaped overlapping boss 3 and the reinforcing boss 33 along the width of the wall panel body 1. When the L-shaped overlapping boss 3 is inserted into the L-shaped overlapping groove 4 on the adjacent wall panel body 1, the reinforcing boss 33 is inserted into the corresponding boss slot 41 on the adjacent wall panel body 1.

[0042] In this embodiment of the utility model, the design of the L-shaped overlapping groove 4 and the boss slot 41 enables multiple wall panel bodies 1 to be spliced ​​together. The L-shaped overlapping boss 3 can be quickly inserted into the L-shaped overlapping groove 4, improving assembly efficiency. The reinforcing boss 33 is embedded into the boss slot 41 to ensure that the wall panel body 1 is assembled compactly and tightly.

[0043] Thermal insulation rock wool 5 is laminated on the lower surface of the wall panel body 1, and its size is the same as the length and width of the wall panel body 1; serrated wall-mounted metal expansion tube 6 is embedded in the pre-drilled round hole in the wall; anchor bolt 7 is inserted into the anchoring round groove 31, passes through the anchoring hole 32 and the thermal insulation rock wool 5, and is threaded into the serrated wall-mounted metal expansion tube 6.

[0044] In this embodiment of the utility model, by using thermal insulation rock wool 5 to be composited on the lower surface of the wall panel body 1, the thermal insulation rock wool 5 and the wall panel body 1 can be modularly designed. On the one hand, it can avoid on-site assembly of thermal insulation materials, thereby shortening the assembly time and improving the assembly efficiency of the exterior wall panel. On the other hand, it can utilize the thermal insulation of the thermal insulation rock wool 5 to ensure the thermal insulation effect of the exterior wall panel. At the same time, it can facilitate the prefabrication and mass production of the exterior wall panel and reduce production costs.

[0045] In this embodiment of the utility model, the use of the sawtooth wall-mounted metal expansion tube 6 enables the anchor bolt 7 to quickly anchor the wall panel body 1 to the building wall, avoiding the problem of the bolt protruding too far when using traditional expansion bolts, which would affect the insertion of the L-shaped overlapping boss 3 into the L-shaped overlapping groove 4. Furthermore, the distance between the wall panel body 1 and the building wall can be controlled by adjusting the anchor bolt 7, making installation and use more convenient.

[0046] In this utility model, when multiple wall panel bodies 1 are assembled, the L-shaped overlapping protrusions 3 on the wall panel body 1 are inserted into the L-shaped overlapping grooves 4 on two adjacent wall panel bodies 1, and the arc-shaped sealing grooves 2 are joined together to form a semi-circular groove. After the multiple wall panel bodies 1 are assembled, the semi-circular groove formed by the joining of the arc-shaped sealing grooves 2 is filled with cement mortar 8. The filling of cement mortar 8 forms a continuous waterproof barrier between the wall panel bodies, which on the one hand ensures the overall flatness of the surface of the wall panel body 1 after assembly, and on the other hand prevents rainwater penetration and improves waterproof durability.

[0047] When using this utility model, the wall panel body 1 is assembled from top to bottom and from left to right.

[0048] First, the staff finds the initial position of the wall panel body 1 on the wall. Then, using the location of the anchor hole 32 corresponding to this position, and by measuring with a level or wall straightedge, they measure and mark the location of the anchor hole 32 on the remaining wall panel body 1.

[0049] Then, the staff used tools to make holes at the marked positions on the wall and installed the sawtooth gecko metal expansion tube 6 into the round holes until all the holes were made and the sawtooth gecko metal expansion tube 6 was assembled.

[0050] Workers can then move the module formed by the wall panel body 1 and the thermal insulation rock wool 5 to the recessed installation position, align the anchor hole 32 with the round hole, and then install the anchor bolt 7 into the sawtooth wall metal expansion tube 6, so that the sawtooth wall metal expansion tube 6 expands and is fixed in the round hole. At the same time, by adjusting the anchor bolt 7, the wall panel body 1 is adjusted to be vertical by using the compression of the anchor bolt 7 to prevent it from tilting.

[0051] Subsequently, the workers can assemble the module formed by the subsequent wall panel body 1 and the thermal insulation rock wool 5 onto the right or lower side of this wall panel body 1, and insert the L-shaped overlapping boss 3 on this wall panel body 1 into the L-shaped overlapping groove 4 on the subsequent wall panel body 1, while inserting the reinforcing boss 33 into the boss slot 41, so that the upper surfaces of the two wall panel bodies 1 are tightly joined. At this time, the anchoring hole 32 is aligned with the round hole. The workers install the anchoring bolt 7 into the sawtooth wall metal expansion tube 6 and tighten the anchoring bolt 7 to keep the subsequent wall panel body 1 vertical.

[0052] Using the above method, the modules formed by the subsequent wall panel body 1 and the thermal insulation rock wool 5 are assembled and installed until all the wall panel bodies 1 are installed.

[0053] Finally, the workers filled the semi-circular grooves formed by the joint of the arc-shaped sealing grooves 2 with cement mortar 8 to fill the gaps between the wall panel bodies 1. At the same time, the cement mortar 8 was also filled onto the L-shaped overlapping protrusions 3 on the bottom and rightmost wall panel bodies 1 to ensure that the wall panel bodies 1 form a flat surface.

[0054] In a specific implementation of this utility model, when assembling the bottommost wall panel body 1, workers manually lay thermal insulation rock wool 5 on the lower part of its assembly position. When assembling the rightmost wall panel body 1, workers manually lay thermal insulation rock wool 5 on the right side of its assembly position. This ensures that thermal insulation rock wool 5 is laid at the L-shaped overlapping protrusions 3 on the bottommost and rightmost wall panel bodies 1, thus guaranteeing the integrity of the insulation layer.
