Description

Technical Field

[0001] The invention relates to the technical field of exterior walls, and in particular to an exterior wall structure. Background Art

[0002] The appearance of PVC exterior wall panels adopts imitation wood texture design, which has a simple and natural beauty. It has a variety of different colors and texture designs. PVC exterior wall panels overcome the shortcomings of traditional architectural dull planes and frequent and complex lines of exterior wall tiles. It has many functions and performances that exterior wall tiles and paints do not have, and the performance-price ratio far exceeds that of exterior wall tiles and exterior wall paints.

[0003] Existing PVC exterior walls are all prefabricated in factories and installed on site, which greatly reduces the workload of on-site construction and has many advantages. However, the existing exterior wall structure design is single, the design strength is not high, and the sound insulation, heat insulation and shock absorption effects need to be further improved; in addition, there is a lack of positioning structure between adjacent exterior walls. During the installation process, it is difficult to ensure the flatness of the exterior wall end face due to the inability to achieve integrated positioning of the exterior wall, which will affect the decorative effect of the entire exterior wall. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides an exterior wall structure with high structural strength, good sound insulation, heat insulation and shock absorption effects, convenient and quick installation and guaranteed installation effect, modular production and installation, and saving manufacturing and construction costs.

[0005] The technical solution adopted by the present invention is:

[0006] An exterior wall structure comprises exterior wall panels, a mounting assembly and a sealing assembly, wherein the exterior wall panels are multiple and the multiple exterior wall panels are arranged side by side through the mounting assembly, and the sealing assembly is arranged between the exterior wall panels;

[0007] The exterior wall panel comprises an upper hollow layer and a lower hollow layer, the upper hollow layer comprises a plurality of upper through holes arranged side by side, the lower hollow layer comprises a plurality of lower through holes arranged side by side, the upper through holes and the lower through holes are arranged correspondingly up and down, reinforcing ribs are formed between adjacent upper through holes, and connecting parts are formed between adjacent lower through holes, and the connecting parts are provided with connecting holes penetrating the upper and lower ends of the exterior wall panel;

[0008] The installation assembly includes a lower connecting bar, an upper connecting bar and a pull rod. There are multiple pull rods that pass through corresponding connecting holes respectively. The lower end and upper end of the exterior wall panel are respectively provided with a lower mounting position and an upper mounting position. The lower connecting bar and the upper connecting bar are respectively arranged at the lower mounting position and the upper mounting position. The two ends of the pull rod extending out of the connecting hole are respectively fixedly connected to the lower connecting bar and the upper connecting bar.

[0009] Since reinforcing ribs are formed between adjacent upper through holes and connecting parts are formed between adjacent lower through holes, the reinforcing ribs and the connecting parts are of an integrated design, which can increase the structural strength of the exterior wall panel; since the connecting part is provided with connecting holes that pass through the upper and lower ends of the exterior wall panel, the design of the connecting holes facilitates the integrated positioning and installation of the exterior wall panel with the lower connecting strip and the upper connecting strip; since the exterior wall panel includes an upper hollow layer and a lower hollow layer, the upper hollow layer includes a plurality of upper through holes arranged side by side, and the lower hollow layer includes a plurality of lower through holes arranged side by side, the design of the plurality of upper through holes and the lower through holes arranged side by side can improve the sound insulation, heat insulation and shock absorption effects while ensuring the structural strength.

[0010] Since multiple exterior wall panels are arranged side by side through the installation component, the installation component includes a lower connecting bar, an upper connecting bar and a pull rod. The pull rod passes through the connecting hole, and the two ends of the pull rod extending out of the connecting hole are respectively fixedly connected to the lower connecting bar and the upper connecting bar. Since the lower connecting bar and the upper connecting bar are located in the same horizontal plane, multiple exterior wall panels are fixed between the lower connecting bar and the upper connecting bar, which can ensure the flushness of the end faces of adjacent exterior wall panels, thereby ensuring the decorative effect of the exterior wall.

[0011] The exterior wall structure can pre-fix and install multiple exterior wall panels as a whole with lower connecting bars and upper connecting bars. During on-site construction, it is only necessary to directly fix the lower connecting bars and upper connecting bars on the installed aluminum alloy keels. Modular production and installation have high construction efficiency and save manufacturing and construction costs.

[0012] Furthermore, in order to achieve a circumferential sealing effect on the exterior wall panel, the sealing assembly includes an A sealing assembly and a B sealing assembly. The exterior wall panel is a rectangular exterior wall panel, and an A sealing assembly is provided between the upper and lower adjacent rectangular exterior wall panels, and a B sealing assembly is provided between the left and right adjacent rectangular exterior wall panels.

[0013] Since the sealing effect of the joints of the existing PVC exterior walls is poor, external water will penetrate into the interior of the exterior wall through the joints, directly affecting the overall service life of the exterior wall. Therefore, the technical solution can achieve a circumferential sealing effect of the exterior wall panel by setting up the A sealing component and the B sealing component.

[0014] In addition, the seams between the existing exterior wall panels need to be provided with anchors to fix the exterior wall panels. This installation method results in seams between adjacent exterior wall panels, which results in serious cold and hot bridge problems at the seams, and is not conducive to heat preservation of the wall. Therefore, the technical solution forms a circumferential sealed seam at the circumferential seam of the exterior wall panels by providing the A sealing component and the B sealing component, which can avoid the problem of cold and hot bridges at the seams between adjacent exterior wall panels.

[0015] Furthermore, in order to better achieve the installation of the exterior wall panels and the sealing effect on the upper and lower ends of the exterior wall panels, the lower connecting strip includes a lower mounting groove with an opening facing downward, and the upper connecting strip includes an upper mounting groove with an opening facing upward, the opening directions of the lower mounting groove and the upper mounting groove are opposite, the through hole is located on the bottom wall of the lower mounting groove and the upper mounting groove, both ends of the pull rod extending out of the through hole do not exceed the lower mounting groove and the upper mounting groove, the nut is located in the lower mounting groove and the upper mounting groove, and the overall invisible fixed installation of multiple exterior wall panels is realized, thereby improving the decorative effect of the exterior wall panels, the lower end and the upper end of the exterior wall panels are respectively provided with a first extension portion and a second extension portion, the A sealing assembly includes a first sealing assembly abutting against the first extension portion and a second sealing assembly abutting against the second extension portion, the first sealing assembly is located on the right side of the lower mounting groove, and the second sealing assembly is located on the right side of the upper mounting groove, and the first sealing assembly and the second sealing assembly are sealingly connected.

[0017] It should be noted that, in the installed state, since the opening of the docking groove on the first sealing component faces downward, it can achieve sealed docking with the docking protrusion and the second sealing strip. The position design of the docking groove can avoid water accumulation in the seams between the upper and lower adjacent exterior wall panels, thereby achieving better sealing and waterproofing effects.

[0018] Furthermore, in order to better achieve the sealing effect between the left and right adjacent exterior wall panels, the left and right sides of the exterior wall panels are respectively provided with a first sealing clamping portion and a second sealing clamping portion, the B sealing component includes a third sealing component clamped with the first sealing clamping portion and a fourth sealing component clamped with the second sealing clamping portion, the third sealing component and the fourth sealing component both include a plurality of continuous sealing areas, the adjacent sealing areas are perpendicular to each other, and sealing docking areas or sealing docking portions are formed between the adjacent sealing areas, the sealing docking area of ​​the third sealing component is sealingly docked with the sealing docking portion of the fourth sealing component, and the sealing docking portion of the third sealing component is sealingly docked with the sealing docking area of ​​the fourth sealing component.

[0019] Due to the provision of multiple continuous sealing areas, adjacent sealing areas are perpendicular to each other, which can achieve multi-faceted continuous sealing, thereby greatly improving the sealing effect at the joints of the exterior wall, thereby extending the service life of the exterior wall; since the sealing docking area of ​​the third sealing component is sealed and docked with the sealing docking part of the fourth sealing component, and the sealing docking part of the third sealing component is sealed and docked with the sealing docking area of ​​the fourth sealing component, a complementary sealing docking mode is formed between the third sealing component and the fourth sealing component, and this design can make the third sealing component and the fourth sealing component, under the condition of unified structural design, cooperate with the exterior wall panel to form a modular installation design structure, which is convenient for modular production and installation, and saves manufacturing and construction costs.

[0020] Furthermore, in order to better achieve the appearance effect of the docking at the left and right seams in the installed state and facilitate the installation of the third sealing assembly and the fourth sealing assembly, the left and right sides of the exterior wall panel are respectively provided with a first opening and a second opening opening facing outward, the first opening is located above the first sealing clip part, and the second opening is located above the second sealing clip part.

[0021] In addition, after the first opening and the second opening are connected, a cavity is formed at the seam, which can achieve a certain thermal insulation effect as a whole. Combined with the setting of the third sealing component and the fourth sealing component, the problem of hot and cold bridges at the seams between the left and right adjacent exterior wall panels is better solved.

[0022] Further, in order to better realize the clamping installation between the third sealing component and the first sealing clamping part, and between the fourth sealing component and the second sealing clamping part, the three sealing areas of the third sealing component are the first upper vertical sealing edge, the first horizontal sealing edge and the first lower vertical sealing edge in sequence, a sealing docking area is formed between the first upper vertical sealing edge and the first horizontal sealing edge, a sealing docking part is formed between the first horizontal sealing edge and the first lower vertical sealing edge, the first sealing clamping part includes a first upper vertical surface, a first horizontal surface and a first lower vertical surface respectively affixed to the first upper vertical sealing edge, the first horizontal sealing edge and the first lower vertical sealing edge, a first clamping protrusion is provided on the first upper vertical surface, a first clamping groove that is clamped and matched with the first clamping protrusion is provided on the first upper vertical sealing edge, a first end clamping protrusion is provided between the first horizontal surface and the first lower vertical surface, and a first end clamping groove that is clamped and matched with the first end clamping protrusion is provided between the first horizontal surface and the first lower vertical surface;

[0023] The three sealing areas of the fourth sealing assembly are the second upper vertical sealing edge, the second horizontal sealing edge and the second lower vertical sealing edge in sequence. A sealing docking portion is formed between the second upper vertical sealing edge and the second horizontal sealing edge, and a sealing docking area is formed between the second horizontal sealing edge and the second lower vertical sealing edge. The second sealing clamping portion includes a second upper vertical surface, a second horizontal surface and a second lower vertical surface respectively fitted with the second upper vertical sealing edge, the second horizontal sealing edge and the second lower vertical sealing edge. A second clamping protrusion is provided on the second upper vertical surface, and a second clamping groove which is clamped with the second clamping protrusion is provided on the second upper vertical sealing edge. A second end clamping protrusion is provided between the second horizontal surface and the second lower vertical surface, and a second end clamping groove which is clamped with the second end clamping protrusion is provided between the second horizontal sealing edge and the second lower vertical sealing edge.

[0024] Furthermore, in order to achieve a better sealing effect, a third sealing strip is provided on the first upper vertical sealing edge, the first horizontal sealing edge and the first lower vertical sealing edge.

[0025] Furthermore, in order to achieve a better sealing effect, a fourth sealing strip is provided on the second upper vertical sealing edge, the second horizontal sealing edge and the second lower vertical sealing edge.

[0026] Furthermore, in order to achieve a better sealing effect, the positions of the third sealing strip and the fourth sealing strip between the first upper vertical sealing edge and the second upper vertical sealing edge, between the first horizontal sealing edge and the second horizontal sealing edge, and between the first lower vertical sealing edge and the second lower vertical sealing edge are staggered.

[0027] The positions of the third sealing strip and the fourth sealing strip between the first lower vertical sealing edge and the second lower vertical sealing edge are staggered. The above design can achieve a sealing effect of three sides and six points, which can greatly improve the sealing effect of the installation joints of the exterior wall panels, thereby extending the service life of the exterior walls.

[0028] In order to ensure the structural strength of the third sealing assembly and the fourth sealing assembly, a reinforcement structure is provided in the sealing docking area.

[0029] In order to ensure the structural strength and installation fit of the third sealing assembly and the fourth sealing assembly, the reinforcement structure is a right-angle reinforcement structure, which includes a vertical surface and a horizontal surface that are perpendicular to each other. The two ends of the right-angle reinforcement structure are respectively integrally formed with the corresponding sealing areas, and the outer sides of the first clamping groove and the second clamping groove both form a first end surface, the vertical surface is flush with the first end surface, the outer end surface of the first end clamping groove and the second end clamping groove in the vertical direction is the second end surface, and the horizontal surface is flush with the second end surface.

[0030] It should be noted that a sealing strip A is formed between the vertical surface and the first end surface, a sealing strip B is formed between the horizontal surface and the second end surface, and a sealing strip C is provided on the first lower vertical sealing edge and the second upper vertical sealing edge. The sealing strip C on the first lower vertical sealing edge is located below the first end clamping groove, and the sealing strip C on the second upper vertical sealing edge is located above the second end clamping groove.

[0031] That is, in the present technical solution, the structures of the third sealing component and the fourth sealing component are the same, including that the setting positions of the A sealing strip, the B sealing strip and the C sealing strip are all the same. During the installation process, it is only necessary to adaptively adjust the angle of the third sealing component or the fourth sealing component according to the different installation positions on the exterior wall panel for matching installation. Since the entire design of the exterior wall panel and the third sealing component and the fourth sealing component are modular in design, the installation is convenient and quick.

[0032] The beneficial effects of the present invention are as follows: since reinforcing ribs are formed between adjacent upper through holes and connecting parts are formed between adjacent lower through holes, the reinforcing ribs and the connecting parts are of an integrated design, which can increase the structural strength of the exterior wall panel; since the connecting part is provided with connecting holes that pass through the upper and lower ends of the exterior wall panel, the design of the connecting holes facilitates the integrated positioning and installation of the exterior wall panel with the lower connecting strip and the upper connecting strip; since the exterior wall panel includes an upper hollow layer and a lower hollow layer, the upper hollow layer includes a plurality of upper through holes arranged side by side, and the lower hollow layer includes a plurality of lower through holes arranged side by side, the design of the plurality of upper through holes and the lower through holes arranged side by side can improve the sound insulation, heat insulation and shock absorption effects while ensuring the structural strength.

[0033] Since multiple exterior wall panels are arranged side by side through the installation assembly, the installation assembly includes a lower connecting bar, an upper connecting bar and a pull rod. The pull rod passes through the connecting hole, and then the exterior wall panels are fixedly connected to the lower connecting bar and the upper connecting bar through nuts. Since the lower connecting bar and the upper connecting bar are located in the same horizontal plane, multiple exterior wall panels are fixed between the lower connecting bar and the upper connecting bar, which can ensure the flushness of the end faces of adjacent exterior wall panels, thereby ensuring the decorative effect of the exterior wall.

[0034] The exterior wall structure can pre-fix and install multiple exterior wall panels as a whole with lower connecting bars and upper connecting bars. During on-site construction, it is only necessary to directly fix the lower connecting bars and upper connecting bars on the installed aluminum alloy keels. Modular production and installation have high construction efficiency and save manufacturing and construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described 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, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0054] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0056] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0057] Embodiment 1:

[0058] like Figure 1-Figure 17 As shown, this embodiment provides an exterior wall structure, including an exterior wall panel 1, a mounting assembly and a sealing assembly. There are multiple exterior wall panels 1 and the multiple exterior wall panels 1 are arranged side by side through the mounting assembly, and the sealing assembly is arranged between the exterior wall panels 1;

[0059] The exterior wall panel 1 includes an upper hollow layer and a lower hollow layer, the upper hollow layer includes a plurality of upper through holes 2 arranged side by side, the lower hollow layer includes a plurality of lower through holes 3 arranged side by side, the upper through holes 2 and the lower through holes 3 are arranged correspondingly up and down, reinforcing ribs 4 are formed between adjacent upper through holes 2, and connecting portions 5 are formed between adjacent lower through holes 3, and the connecting portions 5 are provided with connecting holes 6 that penetrate the upper and lower ends of the exterior wall panel 1;

[0060] The installation assembly includes a lower connecting bar 7, an upper connecting bar 8 and a tie rod 9. There are multiple tie rods 9 and they pass through the corresponding connecting holes 6 respectively. The lower end and the upper end of the exterior wall panel 1 are respectively provided with a lower mounting position 10 and an upper mounting position 11. The lower connecting bar 7 and the upper connecting bar 8 are respectively arranged at the lower mounting position 10 and the upper mounting position 11. The two ends of the tie rod 9 extending out of the connecting hole 6 are respectively fixedly connected with the lower connecting bar 7 and the upper connecting bar 8. Specifically, a through hole 12 is provided at a position opposite to the connecting hole 6 on the lower connecting bar 7 and the upper connecting bar 8. After the two ends of the tie rod 9 extending out of the connecting hole 6 pass through the corresponding through holes 12, the exterior wall panel 1 is fixedly connected with the lower connecting bar 7 and the upper connecting bar 8 through nuts 13.

[0061] Since reinforcing ribs 4 are formed between adjacent upper through holes 2 and connecting portions 5 are formed between adjacent lower through holes 3, the reinforcing ribs 4 and the connecting portions 5 are of an integrated design, which can increase the structural strength of the exterior wall panel 1; since the connecting portion 5 is provided with connecting holes 6 that pass through the upper and lower ends of the exterior wall panel 1, the design of the connecting holes 6 facilitates the integrated positioning and installation of the exterior wall panel 1 and the lower connecting strips 7 and the upper connecting strips 8; since the exterior wall panel 1 includes an upper hollow layer and a lower hollow layer, the upper hollow layer includes a plurality of upper through holes 2 arranged side by side, and the lower hollow layer includes a plurality of lower through holes 3 arranged side by side, the design of the plurality of upper through holes 2 and the lower through holes 3 arranged side by side can improve the sound insulation, heat insulation and shock absorption effects while ensuring the structural strength.

[0062] Since multiple exterior wall panels 1 are arranged side by side through the installation component, the installation component includes a lower connecting bar 7, an upper connecting bar 8 and a pull rod 9, and the pull rod 9 passes through the connecting hole 6, and then the exterior wall panel 1 is fixedly connected with the lower connecting bar 7 and the upper connecting bar 8 through the nut 13. Since the lower connecting bar 7 and the upper connecting bar 8 are located in the same horizontal plane, the multiple exterior wall panels 1 are fixed between the lower connecting bar 7 and the upper connecting bar 8, which can ensure the flushness of the end faces of adjacent exterior wall panels 1, thereby ensuring the decorative effect of the exterior wall.

[0063] The exterior wall structure can pre-fix and install multiple exterior wall panels 1 as a whole with the lower connecting strips 7 and the upper connecting strips 8. During the on-site construction process, it is only necessary to directly fix the lower connecting strips 7 and the upper connecting strips 8 on the installed aluminum alloy keels. The modular production and installation have high construction efficiency and save manufacturing and construction costs.

The exterior wall panel 1 is a rectangular exterior wall panel 1. An A sealing component 14 is provided between the upper and lower adjacent rectangular exterior wall panels 1, and a B sealing component 15 is provided between the left and right adjacent rectangular exterior wall panels 1.

[0067] Since the sealing effect of the joints of the existing PVC exterior wall is poor, external water will penetrate into the interior of the exterior wall through the joints, directly affecting the overall service life of the exterior wall. Therefore, the technical solution can achieve a circumferential sealing effect of the exterior wall panel 1 by setting up the A sealing component 14 and the B sealing component 15.

[0068] In addition, the seams between the existing exterior wall panels 1 need to be provided with anchors to fix the exterior wall panels 1. This installation method results in seams between adjacent exterior wall panels 1, which results in serious cold and hot bridge problems at the seams, which is not conducive to heat preservation of the wall. Therefore, the present technical solution forms a circumferential sealed seam at the circumferential seam of the exterior wall panels 1 by providing the A sealing component 14 and the B sealing component 15, which can avoid the problem of cold and hot bridges at the seams between adjacent exterior wall panels 1.

[0069] Embodiment 3:

Both ends of the pull rod 9 extending out of the through hole 12 do not exceed the lower mounting groove 16 and the upper mounting groove 17. The nut 13 is located in the lower mounting groove 16 and the upper mounting groove 17, and the overall realization of multiple exterior wall panels 1 The invisible fixed installation improves the decorative effect of the exterior wall panel 1.

The docking protrusion 22 and the second sealing strip 23 are sealed and docked with the docking groove 20.

[0075] It should be noted that, in the installed state, since the opening of the docking groove 20 on the first sealing component 14.1 faces downward, it can achieve sealed docking with the docking protrusion 22 and the second sealing strip 23. The position design of the docking groove 20 can avoid water accumulation in the seams between the upper and lower adjacent exterior wall panels 1, thereby achieving better sealing and waterproofing effects.
