Description

Technical Field

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

[0002] Curtain wall is a decorative and protective structure of the exterior wall of a building. It is usually made of glass, metal, stone and other materials and installed on the facade of the building. Among them, metal curtain wall has excellent advantages such as heat insulation, sound insulation and corrosion resistance. It is widely used in large industrial buildings, commercial complexes and high-rise buildings, and aluminum plates are the main metal curtain wall. At present, most of the curtain walls on the market use metal skeletons as intermediate connection structures. The metal skeleton is first fixed on the wall, and then the curtain wall and the metal skeleton are fixed by bolts. Although this fixing method is quick and convenient, when an earthquake occurs, the building will also cause the curtain wall to shake. The transmission of its vibration can easily cause the connection between the curtain wall, the metal skeleton and the building wall to be damaged. After long-term use, there is a risk of the curtain wall falling off. For this reason, although China has disclosed several related patents on shock-absorbing building curtain walls, most of them have problems such as complex structure, high production cost, and inconvenient installation.

[0003] In summary, it is necessary to provide a metal curtain wall with good shock absorption performance, which can effectively reduce the impact on the curtain wall joints when an earthquake occurs. Summary of the invention

The outer surface of the energy absorbing assembly is also connected to a movable skeleton for supporting its shape, and the movable skeleton includes a plurality of "U"-shaped connecting frames and sliders slidably arranged at both ends of each connecting frame, the connecting frame is horizontally arranged on the peripheral side of the first airbag and abuts against its surface, and the ends of the two sliders away from the connecting frame are fixed to the side surface of the curtain wall body, and the side surface of the connecting frame away from the slider abuts against the side surface of the adjacent curtain wall body, and the plurality of connecting frames are arranged at equal distances in a straight line direction and cooperate with the first airbags, and the movable skeleton is provided with two pieces, and is vertically symmetrically arranged with respect to the energy absorbing assembly, and the two movable skeletons are staggered with each other along the length direction of the energy absorbing assembly.

DETAILED DESCRIPTION

[0026] like Figures 1 to 9 As shown,

[0027] An assembled curtain wall structure includes a wall 1 and a connection frame 3 installed on the outer surface of the wall 1 for fixing a curtain wall body 2, wherein the curtain wall body 2 is made of aluminum alloy material, and the connection frame 3 includes a plurality of horizontally arranged transverse connection frames 301 and a plurality of vertically arranged vertical connection frames 302, wherein the transverse connection frames 301 are first fixedly installed on the outer surface of the wall 1 by bolts, and then the vertical connection frames 302 are installed, and the vertical connection frames 302 are fixedly connected to the transverse connection frames 301 by bolts through existing metal connectors (combined with Figure 4 As shown), and erected on the outer surface of the wall 1, each of the horizontal connecting frames 301 is regularly arranged with the vertical connecting frames 302, and together form a plurality of rectangular areas corresponding to the curtain wall body 2, the size of the rectangular area is slightly smaller than the curtain wall body 2, and each of the intersections of the horizontal connecting frames 301 and the vertical connecting frames 302 is provided with a fixed shell 4, the fixed shell 4 is fixedly connected to the vertical connecting frame 302 by bolts, each of the fixed shells 4 is abutted against a right angle side of the matching curtain wall body 2, and any four adjacent fixed shells 4 cooperate and jointly fix the corresponding curtain wall body 2, and the curtain wall body 2 is erected on one side surface of the vertical connecting frame 302, and a gap is left between any two adjacent curtain wall bodies 2, and each of the four right angles of the curtain wall body 2 is provided with a groove matching the fixed shell 4, and the groove is "L" shaped, combined with Figure 6As shown, the surface of each of the fixed shells 4 is elastically slidably connected with a first buffer block 5 that moves in the horizontal direction and a second buffer block 6 that moves in the vertical direction (a spring is provided between the first buffer block 5, the second buffer block 6 and the fixed shell 4, which is not shown in the figure), the first buffer block 5 and the second buffer block 6 are arranged at right angles, and the first buffer block 5 abuts against the vertical surface at the groove, and the second buffer block 6 abuts against the horizontal surface at the groove, wherein the first buffer block 5 and the second buffer block 6 arranged at right angles are evenly spaced around the fixed shell 4, and the four right angles of the curtain wall body 2 abut against the corresponding first buffer block 5 and second buffer block 6.

[0028] Combination Figure 1 and Figure 2 As shown (for the convenience of display, the figure only describes the connection diagram between part of the wall and the curtain wall body), the horizontal connecting frame 301 is installed first and then the vertical connecting frame 302 is installed, and then the curtain wall body 2 is erected on one side surface of the vertical connecting frame 302 through four adjacent fixed shells 4. Since the contact part between each fixed shell 4 and the curtain wall body 2 is elastically slid with the first buffer block 5 and the second buffer block 6, there is a movable margin between the curtain wall body 2 and the fixed shells 4 arranged around it. When an earthquake occurs, even if the wall 1 will simultaneously drive the connecting frame 3 and the fixed shell 4 to vibrate, the first buffer block 5 and the second buffer block 6 absorb the vibration through the spring and effectively reduce the damage to the curtain wall body 2. When horizontal vibration occurs, the four first buffer blocks 5 located around the curtain wall body 2 will move with the curtain wall body 2 under the action of the springs. The stretching or contraction of the spring is used to absorb the impact force of horizontal vibration. Of course, the moving distance of the curtain wall body 2 is limited. When the spring corresponding to the first buffer block 5 is stretched or compressed outside the specified working range, the side surface of the curtain wall body 2 is against the surface of the fixed shell 4 to prevent the curtain wall body 2 from moving too far, resulting in increased inertia and affecting its movement (of course, the surfaces of the first buffer block 5 and the second buffer block 6 in contact with the curtain wall body 2 are bonded with flexible buffer materials to further reduce vibration). Similarly, when vertical vibration occurs, the four second buffer blocks 6 located around the curtain wall body 2 will move with the curtain wall body 2 under the action of the spring to absorb the impact force of the vertical vibration. Under normal circumstances, the first buffer block 5 and the second buffer block 6 will act at the same time and absorb the seismic impact force of the curtain wall body 2 through the spring, effectively reducing the impact of the seismic impact force on the curtain wall body 2.

[0029] In this embodiment, the gap between any two adjacent curtain wall bodies 2 is provided with an energy absorbing component 7, the energy absorbing component 7 includes first air bags 701 arranged equidistantly along a straight line, the first air bags 701 are spherical, and any two adjacent first air bags 701 are connected with second air bags 702 arranged equidistantly, the second air bags 702 are cylindrical, and the volume of the second air bags 702 is smaller than that of the first air bags 701. The first air bags 701 and the second air bags 702 are filled with gas, and the outer surface of the energy absorbing component 7 is also connected with a gas for supporting The movable frame 8 supporting its shape is provided with grooves for accommodating the movable frame 8 on the four sides of the curtain wall body 2. The movable frame 8 includes a plurality of U-shaped connecting frames 801 and sliders 802 slidably arranged at both ends of each connecting frame 801. Each of the connecting frames 801 is horizontally arranged on the peripheral side of the first airbag 701 and abuts against its surface, and the ends of the two sliders 802 away from the connecting frames 801 are fixed to the side surface of the curtain wall body 2 (the free end of the slider 802 is slidably arranged in the slide groove opened on the side surface of the curtain wall body 2, combined with Figure 5 and Figure 8 As shown), a side surface of the connecting frame 801 away from the slider 802 abuts against the adjacent side surface of the curtain wall body 2, and a plurality of the connecting frames 801 are arranged at equal distances in a straight line direction and cooperate with the first airbag 701, and the movable skeleton 8 is provided with two pieces, and is vertically symmetrically arranged about the energy absorbing component 7, and the two movable skeletons 8 are staggered with each other along the length direction of the energy absorbing component 7 (the specific arrangement is shown in the figure), wherein each of the sliders 802 cooperates with the slide groove opened on the surface of the curtain wall body 2, so that the two are fixedly connected.

[0030] Combination Figure 2 As shown, in order to further reduce the impact of earthquake on the curtain wall body 2, an energy absorbing component 7 is provided at the gap between any two adjacent curtain wall bodies 2. When one of the curtain wall bodies 2 is subjected to earthquake impact and moves horizontally to the right, the curtain wall body 2 will not only abut against the corresponding first buffer block 5 to reduce the impact force, but also the side surface of the curtain wall body 2 will simultaneously abut against the surface of multiple connecting frames 801 on one of the movable frames 8 (combined with the surface of the connecting frame 801). Figure 8As shown), the two movable skeletons 8 are close to each other and abut the corresponding first airbags 701 at the same time. After the first airbag 701 is squeezed, it absorbs a part of the impact force on the curtain wall body 2 in a way of deformation. After the first airbag 701 is squeezed, a part of the gas inside it will be squeezed to the second airbag 702, which will cause the second airbag 702 to expand. When the two movable skeletons 8 are close to each other and jointly squeeze the first airbag 701 to a certain extent, the gas volume in the first airbag 701 and the second airbag 702 is approximately equal. At this time, the outer surfaces of the first airbag 701 and the second airbag 702 abut the movable skeleton 8 at the same time and cooperate with each other to reduce the impact force on the curtain wall body 2, which can effectively resist the situation where the curtain wall body 2 shakes greatly, thereby improving the buffering effect of the energy-absorbing component 7 on the curtain wall body 2. When the curtain wall body 2 is subjected to the impact force of the earthquake and moves in the horizontal left direction, the curtain wall body 2 will simultaneously drive the corresponding connecting frame 801 to move together through the slider 802, so that the two movable skeletons 8 are close to each other, and the connecting frame 801 will squeeze the corresponding first airbag 701 while moving. The first airbag 701 is deformed after being squeezed and its internal gas is squeezed into the second airbag 702. The principle of subsequent energy absorption and shock reduction of the first airbag 701 and the second airbag 702 is the same as the operating principle of the curtain wall body 2 after squeezing the corresponding first airbag 701 and the second airbag 702 after the movement, and no further details are given here. Similarly, when the curtain wall body 2 is affected by the earthquake and moves up and down, the movement principle and energy absorption and shock reduction method of the corresponding energy absorption component 7 and the movable skeleton 8 are also the same as described above.

[0031] In summary, when the curtain wall body 2 shakes due to an earthquake, the cooperation between the energy-absorbing components 7 and the movable skeleton 8 arranged around it can effectively alleviate and absorb the impact force. Moreover, when the curtain wall body 2 shakes, the movable skeleton 8 can simultaneously drive multiple energy-absorbing components 7 to deform and absorb the impact force. The multiple energy-absorbing components 7 are linked to each other, which further improves the upper limit of energy absorption and shock reduction of the curtain wall body 2.

[0032] In this embodiment, a vertical circular baffle 803 is provided on the surface of each of the connecting frames 801. The shape of the baffle 803 is the same as the vertical cross-section of the first airbag 701 (both are circular), and the baffle 803 is in contact with the surface of the first airbag 701. All baffles 803 located on the same vertical line are fixedly connected by connecting members. As shown in the figure, the connecting member is in the shape of a rectangular block to connect two adjacent baffles 803.

[0033] By increasing the contact area between the connecting frame 801 and the first airbag 701 through the baffle 803, the squeezing area of ​​the first airbag 701 can be increased, so that the first airbag 701 and the second airbag 702 can effectively reduce and absorb the impact force on the curtain wall body 2, thereby improving the stability of the energy absorbing component 7 and the movable frame 8 during movement.

[0034] In this embodiment, both side surfaces of each fixed shell 4 close to the groove are connected with a first sealing strip 9 that abuts against the surface of the fixed shell 4, and both side surfaces of the fixed shell 4 in contact with the first sealing strip 9 are also connected with a second sealing strip 10, and the second sealing strip 10 is arranged around the edge of the fixed shell 4 and abuts against the surface of the curtain wall body 2.

[0035] As shown in the combined figure, parts of the surfaces of the first sealing strip 9 and the second sealing strip 10 abut against each other, which can fill the gap between the curtain wall body 2 and the fixed shell 4 and limit the position. When the curtain wall body 2 shakes due to an earthquake, the curtain wall body 2 will simultaneously drive the second sealing strip 10 to move and abut and rub against the first sealing strip 9. The first sealing strip 9 and the second sealing strip 10 absorb part of the impact by friction and deformation, thereby further improving the upper limit of energy absorption and shock reduction of the curtain wall body 2.

[0036] In this embodiment, a shielding rubber strip 11 is provided in the gap between any two adjacent curtain wall bodies 2, and one side surface of the shielding rubber strip 11 protrudes in the direction away from the wall 1, and both sides of the shielding rubber strip 11 are connected to a long strip sealing block 12 slidably set on the surface of the curtain wall body 2, and the two ends of the shielding rubber strip 11 are fixedly connected to the surface of the adjacent fixed shell 4 by bonding or snap connection.

[0037] As shown in the figure, the shielding strip 11 is fixed in the gap between two adjacent curtain wall bodies 2 through the cooperation of the shielding strip 11 and the sealing block 12, and the sealing blocks 12 on both sides are slidably connected with the adjacent curtain wall bodies 2, which can effectively prevent external rainwater from leaking into the gap between the adjacent curtain wall bodies 2, prevent rainwater from leaking into and corroding the connecting skeleton 3 and the wall 1 and other structures, effectively improve the sealing between the curtain wall bodies 2, and combine the first sealing strip 9 and the second sealing strip 10 to further improve the sealing between the fixed shell 4 and the curtain wall body 2; and, because one side surface of the shielding strip 11 is raised in the gap between the two adjacent curtain wall bodies 2, when the two adjacent curtain wall bodies 2 shake and approach each other, the raised part of the shielding strip 11 is squeezed and deformed, which can absorb and alleviate the impact force exerted on a small part of the curtain wall body 2, and further improve the upper limit of energy absorption and shock absorption.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
