Description

Technical Field

[0001] The invention relates to the technical field of building curtain walls, in particular to a building curtain wall. Background Art

[0002] The building curtain wall is the outer wall enclosure structure of the building, which does not bear the load-bearing function of the main structure. It is usually composed of panels (such as glass, metal plates, stone plates, ceramic plates, etc.) and supporting structures (such as aluminum beams and columns, steel structures, glass ribs, etc.), and has a certain displacement ability relative to the main structure or self-deformation ability. As a lightweight wall commonly used in modern large and high-rise buildings, the curtain wall not only has a decorative effect, but also has functions such as fire prevention, energy saving, heat insulation, and sound insulation.

[0003] The main function of building curtain walls is to protect buildings, provide external protective structures, and enhance the beauty and practicality of buildings. Curtain walls can resist external factors such as wind loads and temperature changes to ensure the stability and safety of buildings. In addition, as a decorative component of buildings, curtain walls can enhance the overall image and quality of buildings, making them more in line with modern aesthetic requirements.

[0004] When installing existing columns, it is usually necessary to use angle steel to fix the columns in concrete, and embedded parts will be pre-embedded in the concrete in advance to facilitate the installation of curtain walls in the later stage. However, the common embedded parts in the prior art are usually a T-shaped slot, and the installation method of the prior art is to use a bolt with a rectangular end, first put the bolt horizontally into the embedded slot, and then rotate the bolt so that the rectangular end of the bolt is stuck in the embedded slot, and then place a gasket and install the column with angle steel, and use a nut to squeeze and fix it. However, this installation method may cause the bolt embedded in the embedded slot to rotate first when installing the nut, resulting in the bolt being unable to be stuck in the embedded slot; therefore, it does not meet the existing needs, and we have proposed a building curtain wall for this.

[0017] The present invention has the following beneficial effects: 1. The design of the installation limit groove and the installation limit ring ensures that the connection between the outer tube and the inner cardboard can only rotate with each other, and cannot move relative to each other, which ensures the stability of the connection between the inner cardboard and the outer tube. Under the extrusion of the rotation positioning component, the rotation connection shaft fixedly connected to one side of the inner cardboard is driven to rotate. At the same time, due to the limitation of the spiral groove, the inner cardboard can only rotate ninety degrees, and the special design of the embedded groove makes the inner cardboard only go in horizontally. During installation, the user holds the connection outer tube and installs the angle steel at the connection outer tube. The inner pallet is then sent into the embedded groove, and the rotation positioning assembly is squeezed by the plug-in fixing assembly and the bolt tightening assembly to rotate the inner pallet that enters the embedded groove horizontally into a vertical direction. At this time, the connecting outer cylinder is fixed by the workers, and the inner pallet located in the embedded groove is squeezed by the rotation positioning assembly, so that the inner pallet is always in a vertical state and cannot be rotated. This design can effectively ensure that the inner pallet will not rotate during the installation process of the installation assembly, resulting in the inability to install the angle steel on the local concrete wall.

[0018] 2. In order to further ensure the stability of the installation components after installation, the building curtain wall is designed with expansion bolts so that the plug-in inner rod can better fix the angle steel to the wall after installation. After the plug-in inner rod is inserted into the connecting outer tube, the plug-in inner rod is stuck in the connecting outer tube. Due to the design of the positioning groove and the positioning block, the plug-in inner rod cannot be rotated at this time. At this time, the anti-lost rotating shell at the tail of the plug-in inner rod can be rotated to drive the broken groove on the side wall of the plug-in inner rod to bend outward. Through this design, the connecting outer tube that expands and explodes outward fixes the angle steel to the outer surface of the connecting outer tube, thereby further ensuring the stable installation of the angle steel.

[0019] 3. The building curtain wall, through the design of the extrusion component, can drive the internal card to be fixed in the embedded slot when the sliding block is stuck in the driving slot, ensuring that the internal card will not rotate. When the sliding block slides inward, the sliding block first causes the rotating connecting shaft and the internal card to rotate. After the internal card rotates, the sliding block will continue to slide forward in the driving slot until it hits the driving rod and drives the driving rod to slide. Through the sliding of the driving rod, the extruded telescopic inner plate fixedly connected thereto slides forward synchronously. The extruded and retractable outer plates are connected by a pressure release spring. At this time, the extruded and retractable outer plates will first contact the inner wall of the embedded groove. At this time, under the continuous driving of the sliding block, the pressure release spring is compressed and continuously releases the elastic force. At this time, the extruded and retractable inner plates will always exert pressure on the inner wall of the embedded groove under the push of the pressure release spring. Through this design, the internal card can be effectively fixed in the embedded groove to ensure that the internal card cannot rotate, further ensuring the stability of the internal card after installation, and at the same time providing stability support for the subsequent rotation of the anti-loss rotating shell.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0030] Embodiment 1, this embodiment is intended to promote the solution of the problem that the bolts embedded in the embedded grooves may rotate first during installation, resulting in the bolts being unable to be stuck in the embedded grooves. Figures 1 to 8 A building curtain wall includes a curtain wall body 1, the curtain wall body 1 includes a partial concrete wall 11, and a mounting assembly 2 is pre-installed in the partial concrete wall 11. The mounting assembly 2 is used to install a column 12 on the partial concrete wall 11.

[0031] A column 12 is arranged outside the partial concrete wall 11 , two adjacent columns 12 are connected by a cross beam 13 , the side walls of the columns 12 are installed with the cross beam 13 , and the outer side walls of the columns 12 and the cross beam 13 are fixedly connected with glass panels 14 .

[0032] The installation component 2 includes an embedded groove part 21 installed in the local concrete wall 11, an internal clamping plate 22 is installed in the embedded groove part 21, a connecting outer cylinder 23 is installed on one side of the internal clamping plate 22, a rotating connecting shaft 26 is fixedly connected to one side of the internal clamping plate 22, and a rotating positioning component 3 is arranged in the connecting outer cylinder 23.

[0033] An installation limit groove 24 is provided in the internal clamping plate 22 , and an installation limit ring 25 is rotatably connected in the installation limit groove 24 , and one side of the installation limit ring 25 is fixedly connected to the connecting outer cylinder 23 .

[0034] The design of the installation limit groove 24 and the installation limit ring 25 ensures that the connecting outer cylinder 23 and the inner card plate 22 can only rotate with each other, and cannot move relative to each other, thereby ensuring the stability of the connection between the inner card plate 22 and the connecting outer cylinder 23. Under the extrusion of the rotation positioning component 3, the rotating connecting shaft 26 fixedly connected to one side of the inner card plate 22 is driven to rotate. At the same time, due to the limitation of the spiral groove 35, the inner card plate 22 can only rotate ninety degrees, and the special design of the embedded groove part 21 makes the inner card plate 22 can only enter horizontally. During installation, the user holds the connecting outer cylinder 23 and now installs the angle steel 15 on the outside of the connecting outer cylinder 23. Then, the internal clamping plate 22 is sent into the embedded groove 21, and then the rotation positioning component 3 is squeezed by the plug-in fixing component 4 and the bolt tightening component 5, so that the internal clamping plate 22 that enters the embedded groove 21 horizontally is rotated into a vertical direction. At this time, the connecting outer cylinder 23 is fixed by the workers, and the internal clamping plate 22 located in the embedded groove 21 is squeezed by the rotation positioning component 3, so that the internal clamping plate 22 is always in a vertical state and cannot be rotated. Through this design, it can be effectively ensured that during the installation process of the installation component 2, the internal clamping plate 22 will not rotate, resulting in the inability to install the angle steel 15 on the local concrete wall 11.

[0035] The rotation positioning assembly 3 includes a spiral groove 35 formed on the outer wall of the rotation connection shaft 26 . A spiral slider 34 is slidably connected in the spiral groove 35 . The spiral slider 34 is fixedly connected in the sliding block 32 .

[0036] The rotation positioning assembly 3 includes a driving groove 31 provided in the connecting outer cylinder 23, a sliding block 32 is slidably connected in the driving groove 31, a plug-in groove 33 is provided in the sliding block 32, a rotating connecting shaft 26 is plugged in the plug-in groove 33, a spiral slider 34 is fixedly connected in the plug-in groove 33, a long groove 36 is provided in the rotating connecting shaft 26, and the long groove 36 is connected to the spiral groove 35.

[0037] The rotation positioning component 3 can fix the relative position relationship between the internal card plate 22 and the connecting outer cylinder 23 under the pressure of the plug-in fixing component 4 to ensure that there is no rotation between the two. Under the pressure of the plug-in inner rod 41, the sliding block 32 slides forward in the driving slide groove 31. At this time, the spiral slider 34 in the sliding block 32 slides in the spiral groove 35 on the outer wall of the rotating connecting shaft 26. Through this driving method, the internal card plate 22 can be driven to rotate in the embedded groove part 21. However, due to the number of turns of the spiral groove 35, the internal card plate 22 can only rotate ninety degrees, thereby ensuring that the internal card plate 22 can be stuck in the embedded groove part 21, and ensuring that the installation component 2 can install the angle steel 15 on the side wall of the local concrete wall 11. The rectangular design of the driving slide groove 31 and the sliding block 32 can ensure that the sliding block 32 will not rotate during the inward sliding process, thereby causing the rotating connecting shaft 26 and the internal card plate 22 fixedly connected thereto to rotate synchronously.

[0038] A plug-in fixing component 4 is provided at one end of the sliding block 32, and the plug-in fixing component 4 includes a plug-in inner rod 41, which is plugged into the connecting outer tube 23, and one end of the plug-in inner rod 41 abuts against the connecting outer tube 23. A telescopic fixing slot 42 is provided on the side wall of the plug-in inner rod 41, and a triangular anti-slip block 44 is slidably connected in the telescopic fixing slot 42. A fixed clamping spring 43 is fixedly connected to the bottom of the triangular anti-slip block 44, and the bottom of the fixed clamping spring 43 is fixedly connected in the telescopic fixing slot 42.

[0039] After the inner rod 41 is inserted into the sliding block 32 and drives the inner card plate 22 to rotate, in order to further ensure the stability of the inner card plate 22 after rotation, the sliding block 32 needs to be clamped in the driving slide groove 31 to ensure that the sliding block 32 does not shake. By means of the elastic expansion design of the triangular anti-slip block 44 in the plug-in fixing component 4, when the triangular anti-slip block 44 slides to the driving slide groove 31, the triangular anti-slip block 44 slides upward under the action of the fixed clamping spring 43. At this time, one end of the sliding block 32 has slid to the other end of the driving slide groove 31, and The triangular anti-slip block 44 is stuck in one end of the driving slide groove 31. At this time, the sliding block 32 will be squeezed in the driving slide groove 31 and cannot slide. Through this design, the stability of the internal card plate 22 after installation and rotation can be effectively guaranteed. At the same time, due to the triangular design of the triangular anti-slip block 44, this process cannot be reversed. Therefore, the plug-in fixing component 4 cannot be removed by normal methods after installation, thereby ensuring that the internal card plate 22 can always maintain a vertical state after installation, thereby further ensuring the stability of the column 12 after installation.

[0040] A positioning block 46 is fixedly connected to the side of the plug-in inner rod 41 that contacts the sliding block 32, and the positioning block 46 is inserted into the positioning groove 45, which is provided at one end of the sliding block 32. The design of the positioning groove 45 and the positioning block 46 limits the direction in which the plug-in inner rod 41 is inserted into the sliding block 32, thereby ensuring stable operation of the installation process.

[0041] Embodiment 2: This embodiment is intended to facilitate solving the problem that the internal card plate 22 needs to be fixed in the embedded slot 21. This embodiment is an explanation based on Embodiment 1. For details, please refer to Figures 1 to 8 A bolt tightening assembly 5 is provided at one end of the plug-in inner rod 41, and the bolt tightening assembly 5 includes an anti-lost plate 51 fixedly connected to one end of the plug-in inner rod 41, and an anti-lost rotating shell 52 is sleeved on the outer wall of the anti-lost plate 51, and a connecting spring 53 is fixedly connected to one end of the anti-lost plate 51, and the other end of the connecting spring 53 is fixedly connected to one side of a cross ring 55, and the cross ring 55 is rotatably connected in a cross groove 54, and the cross groove 54 is opened in the anti-lost rotating shell 52, and a bolt rod 56 is fixedly connected in the anti-lost rotating shell 52, and the bolt rod 56 is inserted in a bolt groove 57, and the bolt groove 57 is opened in the plug-in inner rod 41.

[0042] An expansion bolt assembly 6 is arranged in the plug-in inner rod 41, and the expansion bolt assembly 6 includes a breaking groove 61 opened on the outer side wall of the outer tube 23, and an ejection cross groove 62 is opened in the plug-in inner rod 41. An ejection rod 63 and an anti-slip plate 65 are slidably connected in the ejection cross groove 62. The anti-slip plate 65 is fixedly connected to the outer side wall of the ejection rod 63, and an ejection spring 64 is fixedly connected to the bottom of the anti-slip plate 65, and the other end of the ejection spring 64 is fixedly connected in the ejection cross groove 62.

[0043] In order to further ensure the stability of the installation component 2 after installation, the expansion bolt is designed so that the plug-in inner rod 41 can better fix the angle steel 15 to the wall after installation. After the plug-in inner rod 41 is inserted into the connecting outer tube 23, the plug-in inner rod 41 is stuck in the connecting outer tube 23. Due to the design of the positioning groove 45 and the positioning block 46, the plug-in inner rod 41 cannot rotate at this time. At this time, the anti-lost rotating shell 52 at the tail of the plug-in inner rod 41 can drive the side wall of the plug-in inner rod 41 at the breaking groove 61 to bend outward. Through this design, the connecting outer tube 23 that expands and explodes outward fixes the angle steel 15 on the outer surface of the connecting outer tube 23, thereby further ensuring the stable installation of the angle steel 15.

[0044] After the plug-in inner rod 41 is stuck in the driving slide groove 31, the anti-lost rotating shell 52 begins to be squeezed and rotated. At this time, the bolt rod 56 in the anti-lost rotating shell 52 will rotate in the bolt groove 57 and move inward as a whole. At this time, one side of the anti-lost rotating shell 52 continuously squeezes one end of the connecting outer cylinder 23, so that the weak point on the outside of the connecting outer cylinder 23 begins to expand outward until it expands to the limit. At this time, the angle steel 15 will be fixed to the outer surface of the local concrete wall 11. In this process, one end of the bolt rod 56 always contacts the bottom of the ejector rod 63, thereby driving the ejector rod 63 to slide upward. Since the ejector rod 63 is arranged at the connecting outer cylinder 23 at the broken groove 61, the sliding of the ejector rod 63 can ensure that the expansion of the weak point of the connecting outer cylinder 23 is outward, thereby ensuring the fixing effect of the connecting outer cylinder 23 on the angle steel 15, and effectively avoiding the wrong force direction at the weak point of the connecting outer cylinder 23, resulting in the inability to expand.

[0045] The design of the ejection spring 64 and the anti-slip plate 65 ensures that the ejection rod 63 will not slide out of the plug-in inner rod 41 before reinstallation. The design of the anti-loss plate 51 forms a telescopic system between the anti-loss plate 51 and the plug-in inner rod 41. The two are a telescopic component, which ensures the integrity of the device. The design of the connecting spring 53 ensures the connection between the plug-in inner rod 41 and the anti-loss rotating shell 52. At the same time, the design of the cross groove 54 and the cross ring 55 in the anti-loss rotating shell 52 ensures that the anti-loss rotating shell 52 will not drive the connecting spring 53 to be subjected to bending shear force during the rotation of the anti-loss rotating shell 52, thereby ensuring the normal use of the connecting spring 53.

[0046] Embodiment 3, this embodiment is intended to promote the solution of the problem that the size of the embedded slot 21 is larger than the size of the inner rotating card plate 22, which causes the inner card plate 22 to shake in the embedded slot 21. This embodiment is an explanation based on the second embodiment. For details, please refer to Figures 1 to 8 An extrusion assembly 7 is provided in the inner card plate 22. The extrusion assembly 7 includes a mounting groove 71 opened in the inner card plate 22. An extrusion telescopic outer plate 72 is slidably connected in the mounting groove 71. A pressure release spring 73 is fixedly connected in the extrusion telescopic outer plate 72. The other end of the pressure release spring 73 is fixedly connected to an extrusion telescopic inner plate 74. The extrusion telescopic inner plate 74 is inserted in the extrusion telescopic outer plate 72. The other end of the extrusion telescopic inner plate 74 is fixedly connected to a driving rod 75. The driving rod 75 is slidably connected in an installation slide groove 76. The installation slide groove 76 is opened in the inner card plate 22.

[0047] The design of the extrusion assembly 7 allows the sliding block 32 to drive the internal card plate 22 to be fixed in the embedded groove 21 during the process of being stuck in the driving slide groove 31, ensuring that the internal card plate 22 will not rotate. During the process of the sliding block 32 sliding inward, the sliding block 32 first causes the rotating connecting shaft 26 and the internal card plate 22 to rotate. After the internal card plate 22 rotates, the sliding block 32 will continue to slide forward in the driving slide groove 31 until it contacts the driving rod 75 and drives the driving rod 75 to slide. Through the sliding of the driving rod 75, the extrusion telescopic inner plate 74 fixedly connected thereto slides forward synchronously. The retractable outer plates 72 are connected by pressure release springs 73. At this time, the extruded and retractable outer plates 72 will first contact the inner wall of the embedded groove part 21. At this time, under the continuous driving of the sliding block 32, the pressure release spring 73 is compressed and continuously releases the elastic force. At this time, the extruded and retractable inner plates 74 will always apply pressure to the inner wall of the embedded groove part 21 under the push of the pressure release spring 73. Through this design, the internal card plate 22 can be effectively fixed in the embedded groove part 21 to ensure that the internal card plate 22 cannot rotate, further ensuring the stability of the internal card plate 22 after installation, and at the same time providing stability support for the subsequent rotation of the anti-lost rotating shell 52.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
