Description

Technical Field

[0001] The present invention relates to the technical field of building decoration engineering, and specifically to a connecting device for exterior decoration plates of multi-story and high-rise buildings. Background Art

[0002] Multi-story and high-rise buildings are exposed to the natural environment for a long time and are easily eroded by natural factors such as wind, rain, and ultraviolet rays. Installing decorative plates can form a protective barrier between the building structure and the external environment, effectively reducing the direct damage of external factors to the building structure and extending the service life of the building.

[0003] When installing decorative plates currently, first, embedment plates are installed by drilling holes in the wall, then adapter pieces are installed on the embedment plates, then main keels are welded on the adapter pieces, and then secondary keels are welded on the main keels. After that, two corresponding T-shaped hanging pieces are first installed on the secondary keel at the lowest layer through bolts, the notch on the decorative plate is aligned with the two T-shaped hanging pieces, so that the decorative plate is placed on the corresponding two T-shaped hanging pieces in an inserted manner, and then two corresponding T-shaped hanging pieces are installed on the secondary keel at the upper position of the decorative plate through bolts, so that the bottom end of the T-shaped hanging piece at the upper position is inserted into the notch at the upper part of the decorative plate. At this time, the installation of a single decorative plate is completed.

[0004] However, there are still some problems with this installation method: when installing the T-shaped hanging pieces on the secondary keel, in order to ensure that the decorative plate can be stably and accurately inserted into the corresponding multiple T-shaped hanging pieces later, the T-shaped hanging pieces need to be strictly perpendicular to the secondary keel after installation to ensure accurate angle when inserted into the notch on the decorative plate. This results in the need to adjust the position of the T-shaped hanging pieces multiple times during installation, making the installation speed of the T-shaped hanging pieces slower, and thus greatly reducing the installation efficiency during large-area installation operations of the decorative plates.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1 - Figure 11 The present application is further described in detail.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 A device for connecting decorative panels for the facades of multi-storey and high-rise buildings comprises a connecting frame 2 arranged on the front side of a wall 1, a plurality of panel bodies 3 are arranged on the front side of the connecting frame 2, the connecting frame 2 comprises a plurality of embedded panels 21 arranged on the front side of the wall 1 by bolts, an adapter 22 is fixedly arranged on the front side of the embedded panel 21, a plurality of main keels 23 distributed in a linear array from left to right are arranged on the plurality of adapters 22, a plurality of secondary keels 24 distributed in a linear array from bottom to top are arranged on the front side of the plurality of main keels 23, a fixing assembly 25 for fixing the main keels 23 and the secondary keels 24 is arranged on the adapter 22. The fixing assembly 25 can be used to complete the installation of the main keels 23 and the secondary keels 24 without welding, thereby simplifying the installation operation.

[0037] See alsoFigure 3 and Figure 4 , two dovetail grooves 7 symmetrically distributed up and down are formed on the left side of the adapter 22, a plurality of dovetail blocks 8 inserted into the dovetail grooves are fixedly arranged on the left side of the main keel 23, a plurality of dovetail grooves 9 linearly arranged from bottom to top are formed on the front surface of the main keel 23, and a dovetail plate 10 inserted into the dovetail groove 9 is fixedly arranged on the rear side of the auxiliary keel 24.

[0038] Refer to Figure 4 , the fixing component 25 includes a rectangular block 251 fixedly arranged on the vertical section inside the adapter 22. A cavity is formed inside the rectangular block 251. A moving block 252 is slidably arranged inside the cavity. A threaded rod 253 is arranged on the right side of the rectangular block 251 in a threaded manner. The left end of the threaded rod 253 penetrates into the cavity and is rotatably connected to the right side of the moving block 252. A fixing block one 254 and an extrusion block 255 are fixedly arranged on the left side of the moving block 252. A fixing block two 256 used in cooperation with the extrusion block 255 is slidably arranged inside the cavity.

[0039] Refer to Figure 3 , Figure 4 , Figure 5 and Figure 10 , a plurality of fixing ports one 12 used in cooperation with the fixing block one 254 are formed on the right side of the main keel 23. The side of the fixing block one 254 away from the moving block 252 penetrates out of the cavity, passes through the adapter 22, and is inserted into the corresponding fixing port one 12. A plurality of fixing ports two 13 used in cooperation with the fixing block two 256 are formed on the bottom of the auxiliary keel 24. The side of the fixing block two 256 away from the extrusion block 255 penetrates out of the cavity, passes through the adapter 22, and is inserted into the corresponding fixing port two 13. The sides of the extrusion block 255 and the fixing block two 256 close to each other are both in a slope shape for cooperation. An L-shaped block 11 for limiting the fixing block two 256 is fixedly arranged on the left side of the extrusion block 255.

[0040] When installing the main keel 23 and the secondary keel 24, first, a plurality of main keels 23 are sequentially installed on a plurality of adapters 22 by means of the insertion of the dovetail block 8 and the first dovetail groove 7. Then, a plurality of secondary keels 24 are sequentially installed on a plurality of main keels 23 by means of the insertion of the dovetail plate 10 and the second dovetail groove 9. At this time, the first fixing port 12 is aligned with the first fixing block 254, and the second fixing port 13 is aligned with the second fixing block 256. Then, the staff can rotate the threaded rod 253 to drive the moving block 252 to move to the right. The movement of the moving block 252 drives the first fixing block 254 to move to the right and insert into the first fixing port 12, which can complete the fixation of the main keel 23. At the same time, during the movement of the moving block 252, the extrusion block 255 will also be driven to move and extrude the second fixing block 256. The second fixing block 256 will move upward under the extrusion and insert into the second fixing port 13, which can complete the fixation of the secondary keel 24. Thus, the installation and connection of the main keel 23 and the secondary keel 24 can be quickly completed.

[0041] Refer to Figure 3 and Figure 6 On the upper part of the secondary keel 24, a plurality of positioning members 4 are provided. The positioning member 4 includes a positioning rod 41 fixedly arranged on the upper part of the secondary keel 24. The upper end of the outer side of the positioning rod 41 is chamfered. On both the left and right sides of the positioning rod 41, positioning blocks 42 are fixedly arranged. The upper ends of the front and rear sides of the positioning block 42 are both inclined planes.

[0042] Refer to Figure 3 、 Figure 8 and Figure 9 On the upper part of the secondary keel 24, there are also a plurality of hanging members 5 corresponding to the number of the positioning members 4 for installing the plate body 3. On the bottom and upper part of the plate body 3, two symmetrically distributed slots 6 are opened on the left and right. And the slots 6 are inserted into the corresponding hanging members 5 for fixing the plate body 3.

[0043] Refer to Figure 7 、 Figure 8 and Figure 9 The hanging member 5 includes a horizontal block 51 and a vertical block 52 fixedly arranged on the front surface of the horizontal block 51. An insertion opening 53 for the positioning rod 41 and the positioning block 42 to pass through is opened on the horizontal block 51. The bottom of the horizontal block 51 contacts the upper part of the secondary keel 24. And the upper and lower sides of the vertical block 52 are respectively inserted into the corresponding slots 6. A plurality of connecting blocks 54 are fixedly arranged on the upper part of the horizontal block 51. The two connecting blocks 54 on the same side are respectively located on the front and rear sides of the corresponding positioning block 42.

[0044] In order to facilitate the installation of the hanging member 5 on the secondary keel 24, after the main keel 23 and the secondary keel 24 are installed, the staff can align the socket 53 on the cross block 51 with the positioning rod 41 and the positioning blocks 42 located on the left and right sides of the positioning rod 41, and then insert the cross block 51 along the direction of the positioning rod 41 and the positioning blocks 42. Since the upper end of the outer side of the positioning rod 41 is chamfered and the upper ends of the front and rear sides of the positioning block 42 are both inclined planes, it is more convenient for the cross block 51 to be inserted on the positioning rod 41 and the positioning blocks 42. Then, the preliminary connection between the hanging member 5 and the secondary keel 24 can be completed. At this time, when the cross block 51 is located on the secondary keel 24, it is perpendicular to the secondary keel 24, which ensures the accuracy of the position when the subsequent vertical block 52 is inserted into the slot 6 on the plate body 3. Compared with the need to adjust the position of the hanging member 5 multiple times when installing and fixing the hanging member 5 with bolts, the installation efficiency of the hanging member 5 is greatly improved.

[0045] Refer to Figure 3 、 Figure 6 and Figure 7 , a limiting member 55 for assisting in limiting the plate body 3 is provided at the upper part of the hanging member 5. A guiding port 14 is opened at the upper part of the cross block 51. The limiting member 55 includes a guiding block 551 slidably arranged in the guiding port 14. A limiting block 552 with a sloping front surface is fixedly arranged at the upper rear side of the guiding block 551. Two limiting rods 553 distributed symmetrically left and right are fixedly arranged at the rear side of the limiting block 552. Limiting ports 15 for the limiting rods 553 to pass through are opened on both the connecting block 54 and the positioning block 42, and one end of the limiting rod 553 away from the limiting block 552 is inserted into the limiting ports 15 on the connecting block 54 and the positioning block 42. A rubber pad 554 is fixedly arranged at the upper front side of the guiding block 551. The bottom of the plate body 3 contacts the upper part of the corresponding rubber pad 554, and the rear side of the plate body 3 abuts against the front surface of the corresponding limiting block 552.

[0046] To facilitate the installation of the plate body 3, after installing the hanging parts 5 on the lowermost secondary keel 24, marble glue can be applied to the notch 6 on the plate body 3, and then the notch 6 on the plate body 3 can be aligned and inserted into the installed vertical block 52. At this time, the corresponding two vertical blocks 52 can be used to initially position the plate body 3. During the process of inserting the plate body 3 onto the vertical block 52, the lower end of the plate body 3 will squeeze the limit block 552. When the limit block 552 is squeezed, it will drive the limit rod 553 to move backward. When the bottom of the plate body 3 is in close contact with the upper part of the rubber pad 554, at this time, the limit rod 553 passes through the limit ports 15 on the connecting block 54 and the positioning block 42, effectively preventing the horizontal block 51 from displacing on the secondary keel 24, thus ensuring the stability of the plate body 3 installed on the vertical block 52. At the same time, using the pushing force generated by the extrusion between the limit block 552 and the plate, the plate body 3 can be further limited, so that the vertical block 52 abuts against the notch 6, preventing the plate body 3 from shifting forward and backward.

[0047] After completing the positioning of the bottom of the plate body 3, continue to install the hanging parts 5 on the secondary keel 24 at the upper position of the plate body 3. At this time, the bottom of the vertical block 52 on the upper secondary keel 24 can be inserted into the notch 6 at the upper part of the plate body 3 (as Figure 8 shown), thus completing the installation of a single plate body 3. When installing the plate body 3 on a large area according to this step, the staff can install multiple plate bodies 3 on the already erected connecting skeleton 2 in sequence. By quickly installing and accurately positioning the hanging parts 5, the installation efficiency of the plate body 3 is greatly improved, and the stability after installation of the plate body 3 and the neatness of all installed plate bodies 3 are ensured.

[0048] Refer to Figure 1 , a lower edge trim 16 is fixedly arranged at the lower front end of the wall body 1, an upper edge trim 17 is fixedly arranged at the upper front end of the wall body 1, and side edge trims 18 are fixedly arranged on both the left and right sides of the wall body 1.

[0049] Refer to Figure 11 , a plurality of rectangular openings 19 are formed on the mutually approaching sides of the lower edge trim 16 and the upper edge trim 17. The upper parts of the plurality of vertical blocks 52 at the uppermost end are inserted into the corresponding rectangular openings 19 at the upper end, and the bottoms of the plurality of vertical blocks 52 at the lowermost end are inserted into the corresponding rectangular openings 19 at the lower end. The bottom of the upper edge trim 17 is in contact with the upper part of the rubber pad 554 at the uppermost end, and the inner vertical section of the upper edge trim 17 abuts against the front surface of the limit block 552 at the uppermost end.

[0050] After installing a plurality of plate bodies 3 on the connecting skeleton 2 in sequence, the lower edge trim 16 can be installed at the lower end of the front side of the wall body 1, and then the upper edge trim 17 can be installed at the upper end of the front side of the wall body 1. And through the extrusion of the upper edge trim 17 on the uppermost limiting block 552, it can be ensured that the uppermost hanging member 5 can also be stably installed on the secondary keel 24, so that the stability of the uppermost plate body 3 after installation can be ensured. Finally, the two side edge trims 18 can be respectively installed on the left and right sides of the front side of the wall body 1, thereby ensuring the overall aesthetics of the wall body 1 after the plate body 3 is installed on the connecting skeleton 2.

[0051] During specific work, when installing the plate body 3, first install the embedded plate 21 on the wall body 1, and then the cooperation of the adapter 22 and the fixing assembly 25 on the embedded plate 21 can complete the installation of the main keel 23 and the secondary keel 24 without welding operations, simplifying the installation operation. Then, through the cooperation of the positioning member 4, the installation of the hanging member 5 can be quickly completed, which can not only ensure the accuracy of the installation position of the hanging member 5, but also greatly improve the installation efficiency of the hanging member 5 compared with the method of installing and fixing the hanging member 5 by bolts.

[0052] Then, when installing the plate body 3, align the notch 6 at the bottom of the plate body 3 with the two hanging members 5 at the corresponding positions and insert them to preliminarily position the plate body 3. During this process, the plate body 3 will extrude the limiting block 552, and then drive the limiting rod 553 to insert into the limiting port 15, so as to effectively prevent the hanging member 5 from displacing on the secondary keel 24, ensuring the stability of the plate body 3 installed on the hanging member 5. At the same time, using the pushing force generated by the extrusion between the limiting block 552 and the plate, the plate body 3 can be further limited to prevent the plate body 3 from shifting forward and backward. When installing the plate body 3 on a large area according to this step, the quick installation and accurate alignment of the hanging member 5 greatly improve the installation efficiency of the plate body 3, and ensure the stability of the plate body 3 after installation and the neatness of all the plate bodies 3 after installation.

[0053] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
