Description

Technical Field

[0001] The invention belongs to the field of exterior wall decoration, and in particular relates to a building energy-saving and heat-insulating exterior wall hanging board and an assembly method thereof. Background Art

[0002] External wall panels are building panels used for external walls, which are hung on the outside of the wall through construction methods such as dry hanging. Due to the location of external wall panels, they must have basic properties such as anti-corrosion, high temperature resistance, anti-aging, no radiation, fire resistance, insect resistance, and no deformation. At the same time, they are also required to have beautiful appearance, simple construction, environmental protection and energy saving, etc.

[0003] When hanging and installing exterior wall panels on a wall, usually a keel is set up on the wall first, and then the connecting hangers are installed on the keel. The exterior wall panels are then installed on the keel through the connecting hangers to complete the installation of the exterior wall panels on the wall. Since the fixation of the exterior wall panels on the keel requires multiple connecting hangers, and the exterior wall panels and the connecting hangers are mostly connected by a snap-on structure, the difficulty of alignment between the two affects the efficiency of installation. At the same time, the installer also needs to maintain the stability of the position of the exterior wall panels while docking the exterior wall panels and the connecting hangers, which puts a heavy burden on the hands. Summary of the invention

[0004] The purpose of the present invention is to provide a building energy-saving and thermal insulation exterior wall hanging panel and its assembly method, which reduces the requirements for docking accuracy during installation, while ensuring construction efficiency and also reducing the burden on hands.

[0005] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical scheme:

[0006] A building energy-saving and heat-insulating exterior wall hanging panel comprises a protective layer and a heat-insulating layer. The protective layer is square and the edges of its four sides are folded over to form hook pieces for installing the protective layer on the wall. The four hook pieces are enclosed to form a accommodating space for accommodating the heat-insulating layer. There is an installation space between the edges of the heat-insulating layer and the hook pieces.

[0007] Further technology of the present invention:

[0008] Preferably, a plurality of reinforcing strips are embedded on the inner side surface of the protective layer, and the reinforcing strips are arranged in a mesh shape.

[0009] Preferably, a decorative layer and a waterproof layer are provided on the outer side of the protective layer in sequence from the inside to the outside.

[0010] The present invention also provides a method for assembling a building energy-saving and heat-insulating exterior wall hanging panel, comprising the following steps:

[0011] Step 1: Install the keels. According to the length of the exterior wall hanging board, a number of longitudinal keels are fixedly installed on the wall at equal intervals. Then, according to the width of the exterior wall hanging board, a number of transverse keels are fixedly installed between adjacent longitudinal keels on the wall at equal intervals.

[0012] Step 2: Install the connector, fix the longitudinal connector on the longitudinal keel at a position opposite to the middle position between two adjacent transverse keels, and fix the transverse connector on the middle position of the transverse keel;

[0013] Step 3: Hang the exterior wall hanging board, hook the hook pieces at the left and right ends of the exterior wall hanging board on the movable hooks of the adjacent longitudinal connecting pieces in turn, then hook the hook piece at the bottom end of the exterior wall hanging board on the fixed hook of the adjacent transverse connecting piece located at the bottom, and then hook the hook piece at the top end of the exterior wall hanging board on the movable hook of the adjacent transverse connecting piece located at the top;

[0014] Step 4: Fix the exterior wall hanging plate and push the exterior wall hanging plate toward the wall so that the movable hooks on the longitudinal connecting piece and the transverse connecting piece change from the movable state to the locked state.

[0015] According to further technology, in step three, there are two movable hooks on the longitudinal connecting member, and the two movable hooks are symmetrically arranged with respect to the longitudinal connecting member. The fixed hook and the movable hook on the transverse connecting member are arranged up and down, and the fixed hook is fixedly connected to the transverse connecting member.

[0016] According to a further technology, the movable hook is slidably connected to the longitudinal connecting member and the transverse connecting member and a tension spring is provided between the two, and two ends of the tension spring are respectively hooked between the movable hook and the longitudinal connecting member or between the movable hook and the transverse connecting member.

[0017] According to a further technology, both the fixed hook and the movable hook are provided with limit strips, and slots for inserting the hook piece are provided between the limit strip and the fixed hook and between the limit strip and the movable hook.

[0018] Further technology, a slot is provided on the movable hook, and two relative positions on the slot are provided with a plurality of limit teeth connected in a straight line, and a locking groove is formed between adjacent limit teeth. The longitudinal connecting member and the transverse connecting member are provided with plug blocks adapted to the slot, and two relative positions on the plug block are provided with a plurality of locking teeth adapted to the locking groove and connected in a straight line, the locking teeth are slidably connected to the plug block and a compression spring is provided between the two, and the two ends of the compression spring respectively abut against the locking teeth and the plug block, and the sliding direction of the locking teeth relative to the plug block is perpendicular to the direction in which the plug block is inserted into the slot, and when the longitudinal connecting member and the transverse connecting member are in an unused state, the adjacent limit teeth and locking teeth abut against each other and the tension spring is in a stretched state.

[0019] The further technology also includes step five, installing the fixing strip, vertically placing the fixing strip between adjacent exterior wall panels, and then clamping the fixing strip on two movable hooks of the longitudinal connecting piece.

[0022] The four hook pieces of the exterior wall hanging board of the present invention enclose a storage space for accommodating the thermal insulation layer. There is an installation space between the edge of the thermal insulation layer and the hook pieces. The structure is simple and the design is reasonable. The four hook pieces of the protective layer also ensure the overall structural strength and stability. The thermal insulation layer can not only play a role of thermal insulation but also sound insulation, thereby improving the use effect of the exterior wall hanging board.

[0023] The connection method of the hook piece part with the movable hook and the fixed hook facilitates the docking between the exterior wall hanging panel and the connecting parts on the keel, and the docking accuracy requirements between the two are low, which reduces the difficulty of construction. At the same time, it also facilitates the alignment of the installation between the exterior wall hanging panels. Since the connecting parts on the keel can provide a certain support for the exterior wall hanging panels, the impact between different operations is reduced and the burden on the hands is alleviated.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be further described in detail below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention but not all. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 , Figure 2 The present embodiment is an energy-saving and thermal insulation exterior wall hanging panel for a building, comprising a protective layer 1 and a thermal insulation layer 2. The protective layer 1 is square and the edges of its four sides are folded over to form a hook portion 11 for installing the protective layer 1 on the wall. The four hook portions 11 enclose a storage space for accommodating the thermal insulation layer 2. There is an installation space 12 between the edge of the thermal insulation layer 2 and the hook portion 11, which facilitates the installation of the hook portion 11 on the keel of the wall.

[0036] In this embodiment, the protective layer 1 is a metal plate, which ensures the strength of the exterior wall hanging board. While facilitating the processing of the hook piece 11 on the protective layer 1, it also ensures the structural strength and stability of the hook piece 11. The insulation layer 2 is a foam board, which can not only play a role of insulation but also sound insulation, thereby improving the use effect of the exterior wall hanging board.

[0037] See also Figure 1 , Figure 2A plurality of reinforcing strips 13 are embedded on the inner side of the protective layer 1 , and the reinforcing strips 13 are arranged in a mesh shape, thereby improving the structural strength of the protective layer 1 .

[0038] See also Figure 2 The outer surface of the protective layer 1 is provided with a decorative layer 31 and a waterproof layer 32 in sequence from the inside to the outside, which improves the visual effect of the exterior wall hanging board while also ensuring the stability of the visual effect of the exterior wall hanging board.

[0039] See also Figure 3-Figure 8 This embodiment provides an assembly method of the building energy-saving and thermal insulation exterior wall hanging board based on the embodiment 1, comprising the following steps:

[0040] Step 1: installing the keels, fixing a plurality of longitudinal keels 41 at equal intervals on the wall according to the length of the exterior wall hanging board, and then fixing a plurality of transverse keels 42 at equal intervals between adjacent longitudinal keels 41 on the wall according to the width of the exterior wall hanging board;

[0041] Step 2: Install the connectors. A longitudinal connector 51 is fixedly installed on the longitudinal keel 41 at a position opposite to the middle position between two adjacent transverse keels 42 , and a transverse connector 52 is fixedly installed on the middle position of the transverse keel 42 ;

[0042] Step 3: Hang the exterior wall hanging board. Hook the hook pieces 11 at the left and right ends of the exterior wall hanging board on the movable hooks 61 of the adjacent longitudinal connecting members 51 in sequence. Then hook the hook piece 11 at the bottom end of the exterior wall hanging board on the fixed hook 62 of the lower horizontal connecting member 52 among the adjacent horizontal connecting members 52. Then hook the hook piece 11 at the top end of the exterior wall hanging board on the movable hook 61 of the upper horizontal connecting member 52 among the adjacent horizontal connecting members 52.

[0043] Step 4: Fix the external wall hanging plate and push the external wall hanging plate toward the wall surface, so that the movable hooks 61 on the longitudinal connecting member 51 and the transverse connecting member 52 change from the movable state to the locked state;

[0044] Step 5: Install the fixing strip 7 . Vertically place the fixing strip 7 between adjacent exterior wall panels, and then clip the fixing strip 7 onto the two movable hooks 61 of the longitudinal connector 51 .

[0045] In this embodiment, in step 1, the outer side surfaces of the longitudinal keel 41 and the transverse keel 42 are both on the same vertical plane, ensuring the flatness of the installation of the exterior wall hanging board, thereby ensuring the installation quality and effect of the exterior wall hanging board.

[0046] In this embodiment, in step three, there are two movable hooks 61 on the longitudinal connecting member 51, and the two movable hooks 61 are symmetrically arranged relative to the longitudinal connecting member 51. The fixed hook 62 and the movable hook 61 on the transverse connecting member 52 are arranged up and down, and the fixed hook 62 is fixedly connected to the transverse connecting member 52.

[0047] See also Figure 5 The movable hook 61 is slidably connected to the longitudinal connecting member 51 and the transverse connecting member 52, and a tension spring 63 is provided between the two. The two ends of the tension spring 63 are respectively hooked between the movable hook 61 and the longitudinal connecting member 51 or between the movable hook 61 and the transverse connecting member 52. While facilitating the movable hook 61 to be pulled outward (at this time, the tension spring 63 is in an elongated state) and hooked on the hook piece 11, it also ensures the stability of the connection between the movable hook 61 and the hook piece 11 during the displacement of the exterior wall hanging board relative to the wall surface, and can also play a certain guiding role in the process of pushing the exterior wall hanging board toward the wall surface to drive the movable hook 61 to move.

[0048] See also Figure 6-Figure 8 The fixed hook 62 and the movable hook 61 are both provided with a limiting strip 8, so that a slot 81 for inserting the hook piece 11 is formed between the limiting strip 8 and the fixed hook 62 and between the limiting strip 8 and the movable hook 61, thereby realizing the positioning connection of the hook piece 11 on the fixed hook 62 and the movable hook 61. In the process of pushing the exterior wall hanging board to the wall, the limiting strip 8 on the fixed hook 62 can support the exterior wall hanging board to a certain extent, and at the same time, it also ensures the pushing effect of the exterior wall hanging board on the movable hook 61 via the hook piece 11, thereby ensuring that the movable hook 61 on the longitudinal connecting member 51 and the transverse connecting member 52 changes from an active state to a locked state, thereby achieving the purpose of installing the exterior wall hanging board on the wall.

[0049] See also Figure 5-Figure 7The movable hook 61 is provided with a slot 91, and two opposite positions on the slot 91 are provided with a plurality of limiting teeth 92 connected in a straight line in sequence, and a locking groove 93 is formed between adjacent limiting teeth 92. The longitudinal connecting member 51 and the transverse connecting member 52 are provided with a plug block 94 adapted to the slot 91, and two opposite positions on the plug block 94 are provided with a plurality of locking teeth 95 adapted to the locking groove 93 and connected in a straight line in sequence, and the locking tooth 95 is slidably connected to the plug block 94 and a compression spring 96 is provided therebetween, and the two ends of the compression spring 96 respectively abut against the locking tooth 95 and the plug block 94, and the sliding direction of the locking tooth 95 relative to the plug block 94 is perpendicular to the direction in which the plug block 94 is inserted into the slot 91. When the longitudinal connecting member 51 and the transverse connecting member 52 are in an unused state, the adjacent limiting teeth 92 and the locking teeth 95 abut against each other and the tension spring 63 is in a stretched state. By coordinating the structures on the longitudinal connecting member 51 and the transverse connecting member 52 with the structure on the movable hook 61, the exterior wall hanging panel can be fixed on the wall during the operation of fitting the exterior wall hanging panel to the wall, thereby improving the convenience and efficiency of the operation and allowing a certain amount of small adjustment space to the left and right of the installation position of the exterior wall hanging panel.

[0050] When the external wall hanging plate pushes the movable hook 61 to move, the plug block 94 is inserted into the slot 91. At this time, the tension spring 63 contracts, and in this process, the locking tooth 95 extends into the plug block 94 due to the resistance of the limit tooth 92. At this time, the compression spring 96 is compressed. At the same time, when the locking tooth 95 and the locking groove 93 are relative to each other, the locking tooth 95 extends from the plug block 94 and enters the locking groove 93 under the action of the compression spring 96 to restore its original state. At this time, the movable hook 61 on the longitudinal connecting member 51 and the transverse connecting member 52 is in a locked state.

[0051] In this embodiment, a compression spring 96 is separately provided between each locking tooth 95 and the plug block 94, so as to reduce the difficulty of changing the movable hook 61 from an active state to a locked state when the exterior wall hanging panel is pushed toward the wall, so that the exterior wall hanging panel can be quickly hung on the wall in a state where it can be moved slightly, thereby facilitating the subsequent operation of stably fixing the exterior wall hanging panel on the wall and aligning the exterior wall hanging panels.

[0052] See also Figure 8 The fixing strip 7 includes a panel 71, the width of which is greater than the gap distance between adjacent exterior wall panels. The panel 71 is provided with two clips 72 which are symmetrically arranged with respect to the panel 71. The clips 72 are inclined relative to the panel 71. The clips 72 are provided with convex strips 73. The limiting strip 8 is provided with a groove 82 for accommodating the convex strips 73. While strengthening the connection strength and stability between the exterior wall panel and the longitudinal connector 51, it can also improve the overall appearance visual effect of the exterior wall panel installation.
