Description

Technical Field

[0001] The utility model relates to the technical field of home decoration, in particular to a dry hanging wall panel installation structure. Background Art

[0002] The indoor wall adopts dry hanging installation wallboard, which is a new construction technology. It can be installed in a standardized manner without construction waste. At the same time, it is not necessary to pre-treat the rough wall surface, making the decoration convenient and quick. The existing dry hanging installation wallboard installation method is: first fix the keel frame on the wall through wall nails, then level the keel frame, and finally fix the wallboard on the keel frame, but the installer needs to spend a lot of time to level the wall surface, which affects the efficiency of decoration. However, there are multiple walls in the room. During the installation process one by one, when there is an error in the leveling of two adjacent walls, the gap between the wall panels will be uneven; on the one hand, the installer needs to perform secondary processing and adjustment on the length of the keel and wallboard according to the situation of the installation site, which not only further reduces the decoration efficiency, but also the secondary processing will damage the edge sealing of the wallboard, resulting in the overall aesthetics being destroyed; therefore, in order to solve the problem of aesthetics, the usual practice is to set a special positive angle line or negative angle line to hide the edges of the two adjacent wall panels for decoration, but this makes the installation structure more complicated and further reduces the installation efficiency. Utility Model Content

[0003] In view of the problems existing in the installation of existing dry-hanging wall panels, the utility model aims to provide a wall panel installation structure with high installation efficiency, stronger overall appearance and more reliable structure.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A dry-hanging wall panel installation structure is used to install wall panels on more than two continuous vertical walls, including a plurality of keels and the wall panels installed on the keels through a connecting assembly, and also includes a plurality of metal profile columns vertically arranged corresponding to each wall corner line, a plurality of metal profile beams used for horizontally connecting between the top ends and bottom ends of two adjacent columns, and wall nails used to lock the beams, the columns and / or the keels to the wall; the column includes two vertical installation plates that are integrally formed and perpendicular to each other to form a positive angle or a negative angle, and the two ends of the beam are respectively locked and installed on the two installation plates corresponding to the same side wall surface on the two adjacent columns.

[0006] The beneficial effect of this solution is that: during the decoration process, it is only necessary to first set columns corresponding to each wall corner line, and then use a number of beams to connect and fix two adjacent columns corresponding to the top and bottom positions, so that an integral frame is formed between each wall surface, and then the wall panels only need to be installed on the frame through the keel. During the installation process, it is only necessary to level the frame, and there is no need to level a number of keels on each wall surface separately. Compared with the existing dry hanging installation method, the installation efficiency is greatly improved, and each wall surface forms an integral frame, and the reliability of the wall panel installation structure is higher; because the frame is leveled as a whole, the precise verticality can be guaranteed between the wall panels corresponding to each wall surface, so that at the wall corner line, the side end surface of one wall panel can be tightly against the surface of the other wall panel to achieve tight splicing, and compared with the existing dry hanging installation method, the appearance is more integrated, and there is no need to set up additional corner line structures for edge shielding and decoration; after the frame installation is completed in advance, the installation size of each wall surface is determined, so the keel and the wall panel can be processed in the factory according to the size, and there is no need for secondary processing at the installation site, which further improves the installation efficiency and the appearance is more integrated.

[0007] A preferred solution is that the column is also integrally formed with a baffle which is parallel to the column angle line and protrudes vertically from each mounting plate toward the side away from the wall, and a mounting surface at a right angle is formed between the outer side surface of the baffle away from the column angle line and the outer side surface of the mounting plate away from the wall, the beams corresponding to the same wall have the same length, and both ends of the beam are respectively abutted and locked on the two mounting surfaces corresponding to the same side wall on the two adjacent columns.

[0008] The beneficial effect of the above scheme is that since the beams corresponding to the same wall surface are of equal length, each beam is installed against the top between the right-angle mounting surfaces on the same side of two adjacent columns. After the walls are connected into a whole, leveling can be automatically completed without repeated measurement and adjustment, further improving the installation efficiency.

[0009] A preferred solution is that the lengths of the columns are equal, and the top surface of the beam corresponding to the top end of the column and the bottom surface of the beam corresponding to the bottom end of the column both have a first C-shaped groove extending along the length direction of the beam, and the bottom surface of the first C-shaped groove is flush with the end surface of the column, and also includes a first angle code at a right angle fixed to the end surface of each column in the horizontal direction, and the two arms of the first angle code are adaptively inserted and locked in the first C-shaped grooves of the two adjacent beams.

[0010] The beneficial effects of the above scheme are as follows: the first angle code is used to connect the column and the two adjacent beams at the top and bottom ends respectively. Since the first angle code is a right angle and is fixed on the end face of the column, it can not only ensure the verticality of the column and the two adjacent beams on the horizontal plane and two mutually perpendicular vertical planes, but also strengthen the connection strength between the three to avoid deformation of the frame; the two arms of the first angle code are adaptively inserted into the first C-shaped grooves of the two adjacent beams, so that the angle between the beam and the angle code cannot change, thereby effectively preventing the frame from tilting and deforming, and further improving the connection strength.

[0011] A preferred solution is that the bottom surface of the beam corresponding to the top end of the column and the top surface of the beam corresponding to the bottom end of the column both have a second C-shaped groove extending along the length direction of the beam, and the side surface of each baffle away from the angle line of the column has a third C-shaped groove corresponding to the second C-shaped groove, and the second C-shaped groove and the third C-shaped groove are fixed by a second right-angled angle code arranged vertically, and the two arms of the second angle code are respectively adaptively inserted and locked in the second C-shaped groove and the third C-shaped groove.

[0012] The beneficial effect of the above scheme is: a second angle code is set, and the two arms are respectively inserted and locked in the second C-shaped groove of the crossbeam and the third C-shaped groove of the column baffle, which can not only support the crossbeam and improve its load-bearing capacity, but also further improve the connection strength, ensure the verticality of the crossbeam and the column, and effectively prevent the frame from tilting and deforming.

[0013] A preferred solution is that a plurality of the keels are parallel to the cross beam and are arranged at intervals along the height direction of the column, and the two ends of the keels are locked on the mounting surface; a supporting edge is extended from the bottom edge of the cross beam corresponding to the top end of the column to the side away from the wall surface, and a top decorative panel attached to the outer surface of the cross beam is supported on the supporting edge, and the top surface of the top decorative panel is not lower than the top surface of the corresponding cross beam, and the wall panel and the cross beam clamp and fix the top decorative panel, and the top surface of the wall panel is lower than the top surface of the top decorative panel.

[0014] The beneficial effects of the above scheme are as follows: the wall panels are fixed to the columns through the keels, while the ceiling panels are clamped on the rear side of the top of the wall panels. The ceiling panels are used to form a shielding at the top edge of the wall and form a decorative top line. Since the ceiling panels are not fixed to the wall panels, when the height of the wall panels is adjusted, the shielding and decorative effects of the ceiling panels will not be affected. The ceiling panels are supported by the supporting edges and clamped by the wall panels and beams, so there is no need for locking nails to fix them. The installation is simple and quick and will not move.

[0015] A preferred solution is that a plurality of fixing plates are locked at intervals along the bottom edge of the back side of the wall panel, each of the fixing plates extends a horizontal plate vertically toward one side of the wall, and a vertical height adjustment bolt is threadedly engaged on the horizontal plate, and the bottom end surface of the height adjustment bolt is supported on the top surface of the beam corresponding to the bottom end of the column; the fixing plate extends downwardly into an extension plate, and a skirting board is fixed along the outer side of each extension plate.

[0016] The beneficial effects of the above scheme are: the bottom end surface of the height adjustment bolt is supported by the top surface of the beam and is exposed at the bottom edge of the wall panel. By turning the height adjustment bolt, the height of the wall panel can be adjusted, further improving the installation efficiency; and the skirting board is fixed by an extension piece to cover the lower part of the wall panel and form a decorative baseboard, so that the skirting board is easy to install and can move up and down with the wall panel to ensure a seamless connection between the two.

[0017] In a preferred embodiment, the wall nail includes a first threaded section for locking with the wall, a second threaded section vertically passing through the beam or column, a rotation groove arranged on the outer end surface, and a nut threadedly engaged with the second threaded section and located on the inner and outer sides of the beam or column.

[0018] The beneficial effect of the above scheme is that during installation, the wall nails are passed through the beams, columns and / or keels and locked to the wall surface by the first threaded section, and then the distance between the beams, columns and / or keels and the wall surface can be adjusted by rotating the nuts on the inner and outer sides, and the relative positions of the beams, columns and / or keels and the wall nails are fixed, so that leveling and fixing are quick and easy, and the installation efficiency is further improved.

[0029] The utility model is further described below in conjunction with the accompanying drawings:

[0030] refer to Figures 1 to 9 A dry-hanging wall panel installation structure of the present embodiment is used to install wall panels 2 on more than two continuous vertical walls 1, including a plurality of keels 3, and wall panels 2 installed on the keels 3 through a connecting assembly, and also includes a plurality of metal profile columns 4 vertically arranged corresponding to each wall corner line, a plurality of metal profile beams 5 used for horizontally connecting between the top ends and the bottom ends of two adjacent columns 4, and wall nails 9 used for locking the beams 5, the columns 4 and / or the keels 3 to the wall 1; the column 4 includes two vertical mounting plates 41 integrally formed and perpendicular to each other to form a positive angle or a negative angle, and the two ends of the beam 5 are respectively locked and installed on the two mounting plates 41 on the two adjacent columns 4 corresponding to the same side wall 1.

[0031] During installation, the space dimensions are measured in advance, and then the columns 4 and keels 3 of suitable lengths are processed according to the dimensions; when building the frame, the columns 4 are first set corresponding to each wall corner line, and it is preferred that the columns 4 are of the same height; then the two adjacent columns 4 are connected with the beams 5 corresponding to the top and bottom positions, and the fixation is completed after leveling, so that an integral frame is formed between the walls 1, and each connection point between the beams 5 and the columns 4 is locked by at least two sets of bolts; after completing the construction of the frame, the precise installation dimensions of the width of each wall 1 can be obtained, and then the panels and keels 3 are processed in the factory according to the installation dimensions; when installing the wall panels 2 later, it is only necessary to first fix the keels 3 on the frame composed of the columns 4 and the beams 5, and then install the wall panels 2 on the keels 3 through connecting components such as buckles and hooks. At the corresponding wall corner line, the side end surfaces of the first wall panel 2 of the two adjacent wall panels 2 can be tightly pressed against the surface of the second wall panel 2, and the two wall panels 2 are tightly pressed against each other with a straight gap. At this time, the corresponding side end surfaces of the second wall panel 2 are hidden, and even if there is a size error, it will not leak out and affect the appearance. During the installation process, it is only necessary to level the frame without leveling several keels 3 of each wall 1 separately. Compared with the existing dry-hanging installation method, the installation efficiency is greatly improved, and each wall 1 forms an integral frame, and the reliability of the wall panel 2 installation structure is higher; because the frame is leveled as a whole, the precise verticality can be guaranteed between the wall panels 2 corresponding to each wall 1, so that at the corner line, the side end surface of the wall panel 2 on one side can be tightly against the surface of the other wall panel 2 to achieve tight splicing. Compared with the existing dry-hanging installation method, the appearance is more integrated, and there is no need to set up additional corner line structures for edge shielding and decoration; after the frame installation is completed in advance, the installation size of each wall 1 is determined, so the keels 3 and wall panels 2 can be processed in the factory according to the size, without the need for secondary processing at the installation site, further improving the installation efficiency and making the appearance more integrated.

[0032] A preferred solution is that the column 4 of this embodiment is also integrally formed with a baffle 42 which is parallel to the corner line of the column 4 and protrudes vertically from each mounting plate 41 toward the side away from the wall 1. A right-angle mounting surface 400 is formed between the outer side surface of the baffle 42 away from the corner line of the column 4 and the outer side surface of the mounting plate 41 away from the wall 1. The beams 5 corresponding to the same wall 1 have the same length, and both ends of the beam 5 are respectively abutted and locked on the two mounting surfaces 400 on the two adjacent columns 4 corresponding to the same side wall 1.

[0033] The cross beams 5 corresponding to the same wall surface 1 are of equal length, and the cross beams 5 of the metal profile are in the shape of a square column as a whole, so the size and shape of the cross beams 5 are accurate. At this time, the holes for bolt connection on the columns 4 and the cross beams 5 can also be pre-processed. During installation, each cross beam 5 is installed between the right-angle mounting surfaces 400 on the same side of two adjacent columns 4. After the walls 1 are connected as a whole, leveling can be automatically completed without repeated measurement and adjustment, further improving the installation efficiency.

[0034] A preferred solution, in this embodiment, the lengths of the columns 4 are equal, and the top surface of the beam 5 corresponding to the top of the column 4 and the bottom surface of the beam 5 corresponding to the bottom of the column 4 both have a first C-shaped groove 51 extending along the length direction of the beam 5, and the bottom surface of the first C-shaped groove 51 is flush with the end surface of the column 4, and also includes a first angle code 52 at a right angle fixed to the end surface of each column 4 in the horizontal direction, and the two arms of the first angle code 52 are adaptively inserted and locked in the first C-shaped grooves 51 of the two adjacent beams 5.

[0035] During installation, before the cross beam 5 and the column 4 are fixed by bolts, the first angle code 52 is first fixed to the top and bottom surfaces of the column 4, and then the arms of the first angle code 52 corresponding to the two adjacent cross beams 5 are inserted into the first C-shaped groove 51, so that the column 4 and the cross beam 5 are basically connected, and then the first angle code 52 is fixed to the cross beam 5 by bolts, and the cross beam 5 is fixed to the column 4 by bolts. The first angle code 52 is used to connect the column 4 and the two adjacent cross beams 5 at the top and bottom respectively. Since the first angle code 52 is a right angle and fixed to the end surface of the column 4, it can not only ensure the verticality of the column 4 and the two adjacent cross beams 5 on the horizontal plane and the two mutually perpendicular vertical planes, but also strengthen the connection strength between the three to avoid deformation of the frame; the two arms of the first angle code 52 are adaptively inserted into the first C-shaped grooves 51 of the two adjacent cross beams 5, so that the angle between the cross beam 5 and the angle code cannot change, thereby effectively preventing the frame from tilting and deforming, and further improving the connection strength.

[0036] A preferred solution, in this embodiment, the bottom surface of the beam 5 corresponding to the top end of the column 4 and the top surface of the beam 5 corresponding to the bottom end of the column 4 both have a second C-shaped groove 53 extending along the length direction of the beam 5, and the side surface of each baffle 42 away from the corner line of the column 4 has a third C-shaped groove 421 corresponding to the second C-shaped groove 53, and the second C-shaped groove 53 and the third C-shaped groove 421 are fixed by a vertically arranged second right-angle code 54, and the two arms of the second angle code 54 are respectively adaptively inserted and locked in the second C-shaped groove 53 and the third C-shaped groove 421.

[0037] During installation, before the cross beam 5 and the column 4 are locked by bolts, the second angle code 54 is first locked in the third C-shaped groove 421 of the baffle plate 42 of the column 4, and then the arms of the second angle code 54 corresponding to the two adjacent cross beams 5 are inserted into the second C-shaped groove 53, and the column 4 and the cross beam 5 are basically connected, and then the second angle code 54 and the cross beam 5 are locked by bolts. The second angle code 54 is set, and the two arms are respectively inserted and locked in the second C-shaped groove 53 of the cross beam 5 and the third C-shaped groove 421 of the baffle plate 42 of the column 4, which can not only support the cross beam 5 and improve its load-bearing capacity, but also further improve the connection strength, and ensure the verticality of the cross beam 5 and the column 4, and can effectively prevent the frame from tilting and deforming.

[0038] A preferred solution is that the several keels 3 of this embodiment are parallel to the cross beam 5 and are arranged at intervals along the height direction of the column 4, and the two ends of the keels 3 are locked on the installation surface 400; the bottom edge of the cross beam 5 corresponding to the top end of the column 4 extends a supporting edge 55 toward the side away from the wall 1, and the supporting edge 55 supports a top decorative panel 6 attached to the outer surface of the cross beam 5, and the top surface of the top decorative panel 6 is not lower than the corresponding top surface of the cross beam 5, and the wall panel 2 and the cross beam 5 clamp and fix the top decorative panel 6, and the top surface of the wall panel 2 is lower than the top surface of the top decorative panel 6.

[0039] The bolt holes of the keel 3 can be pre-processed according to the size. During installation, the two ends of the keel 3 are locked on the columns 4 by bolts, and the suspended part of the keel 3 can be supported and leveled by a number of wall nails 9 and other structures; then the top decorative plate 6 is placed on the supporting edge 55 of the beam 5, and then the wall panel 2 is installed on the keel 3 through the connecting assembly. The top of the wall panel 2 presses and fixes the top decorative plate 6 so that it cannot be removed. There are many connection schemes between the wall panel 2 and the keel 3 in the prior art, and the connection components are not the core of the present application, so they will not be described in detail; the wall panel 2 is fixed to the column 4 through the keel 3, and the top decorative panel 6 is clamped on the rear side of the top of the wall panel 2. The top decorative panel 6 is used to form a shielding at the top edge of the wall 1 and form a decorative top line. Since the top decorative panel 6 is not fixed to the wall panel 2, when the height of the wall panel 2 is adjusted, the shielding and decorative effects of the top decorative panel 6 will not be affected; the top decorative panel 6 is supported by the supporting edge 55 and clamped by the wall panel 2 and the beam 5, so it does not need to be fixed with nails, and the installation is simple and quick and will not move.

By rotating the height adjustment bolt 73, the height of the wall panel 2 can be adjusted, further improving the installation efficiency; and the skirting board 8 is fixed by the extension piece 74, which is used to cover the lower part of the wall panel 2 and form a decorative baseboard, so that the skirting board 8 is easy to install and can move up and down with the wall panel 2 to ensure a seamless connection between the two.
