Description

Technical Field

[0001] The invention relates to the technical field of curtain wall installation, and in particular to a self-locking installation structure for assembled building curtain walls. Background Art

[0002] The installation of building curtain walls mainly uses two parts: aluminum frames and fasteners. In essence, the installation is carried out through fastener structures such as expansion screws. Taking the glass curtain wall as an example, during the installation, the stability of the installation position must be ensured first, and the docking stability of each glass curtain wall must be ensured secondly. Take the relevant content in the publication number CN115288334A as an example.

[0003] It should be noted that: because multiple curtain walls need to be "spliced", when the position of one of the curtain walls is offset, it will gradually "radiate" to the curtain wall structures in other positions, which will directly affect the installation position of the overall curtain wall structure. In addition, the horizontality between the curtain walls is also one of the reference factors for the operation. For this, precise control of the layout operation is required to ensure the operation position. However, the curtain wall installation process is an aerial operation and the operation is difficult. This application proposes a solution to this problem. Summary of the invention

[0004] The purpose of the present invention is to provide a self-locking installation structure for assembled building curtain walls. During the high-altitude operation of building curtain wall construction, because multiple curtain walls are "spliced", when there is a deviation in the position of one of the curtain walls, it will directly affect the overall installation position.

[0005] The object of the present invention can be achieved by the following technical solution: A self-locking installation structure for an assembled building curtain wall, comprising a curtain wall body, the curtain wall body being arranged equidistantly in a linear direction, a central connection component being arranged on the central area of ​​the curtain wall body in a plurality of adjacent positions, and a decorative component being arranged at the gap between the curtain wall bodies in two adjacent positions;

[0006] The decorative component is composed of a decorative plate, a directional plug plate and a bidirectional spring frame, and the central connection component includes a fixed stud, a directional screw sleeve, an expansion stud and a movable cone plate. The fixed stud passes through the directional screw sleeve downward, and the lower end of the fixed stud is threadedly connected to the expansion stud. The movable cone plate is installed at the outer position of the directional screw sleeve, and the movable cone plate is arranged in a ring array along the center point of the directional screw sleeve. An outer expansion wheel corresponding to the movable cone plate is rotatably installed in the fixed stud;

[0007] A connecting pin is installed on the outer wall of the outer expansion and compression wheel, and connecting column pins corresponding to the connecting pin are arranged at both ends of the bidirectional spring frame.

[0008] It is further configured as follows: the bidirectional spring frame is parallel to the length direction or width direction of the curtain wall body, and the bidirectional spring frame is composed of two arch frames, and the middle end position of the arch frame is in a curved arch shape along the direction close to the curtain wall body.

[0009] It is further configured as follows: the directional plug plate is arranged at an inner position of the bidirectional spring frame, and the decorative plate is located at an upper position of the directional plug plate and is fixedly connected to the directional plug plate.

[0010] It is further configured that: notches corresponding to the fixing studs are provided at both ends of the decorative plate.

[0011] It is further configured as follows: a connecting column is arranged at a position below the fixed stud corresponding to the directional screw sleeve, a supporting foot corresponding to the curtain wall body extends from the connecting column, and a supporting rubber plate corresponding to the curtain wall body is installed on each of the supporting feet.

[0012] It is further configured as follows: a high-strength spring is arranged on the middle part of the fixing stud corresponding to the connecting column and the expansion screw sleeve.

[0013] It is further configured that: the upper end position of the movable cone plate is installed on the directional screw sleeve, and the inner diameter of the movable cone plate decreases from top to bottom.

[0014] It is further configured as follows: a directional groove corresponding to the outer expansion wheel is opened on the inner wall of the movable cone plate.

[0015] It is further configured as follows: bevels are provided on the outer wall positions of the connecting bayonet pin and the connecting column pin that are close to each other, and the bevels on the connecting bayonet pin and the connecting column pin are arranged in opposite directions.

[0016] It is further configured that: a connection slot corresponding to the curtain wall body is opened on the outer wall of the directional screw sleeve.

[0017] The present invention has the following beneficial effects:

[0018] 1. The overall structure is designed to provide pressure for the assembly process of each curtain wall body in a modular way for the construction of the curtain wall. Its essence is to set a central connection component in the center area of ​​the four curtain wall bodies. The central connection component is improved and optimized based on conventional studs and expansion screws. Taking the fixed stud as an example, when the fixed stud moves downward, it will also synchronously drive the outer expansion wheel to deform outward. Specifically, the rotational force of the fixed stud is converted into a horizontal force through the connecting pin and the connecting column pin, thereby providing linear pressure to the bidirectional spring frame in the corresponding position. The purpose is to cause the bidirectional spring frame to deform in the direction pointing to the curtain wall body, thereby squeezing the curtain wall body, and making each curtain wall body fit and move more closely to ensure the installation position of each curtain wall body;

[0019] 2. In combination with the above content, it is necessary to explain again that the number and direction of the two-way spring frames correspond to the installation method of the curtain wall body. With the deformation process of the two-way spring frames, the curtain wall body can be extruded along the length and width directions. With the modular design, the interactive pressure of the curtain wall bodies at each adjacent position is used to achieve the position during the installation process.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0029] Embodiment 1: In conventional curtain wall construction, because multiple curtain walls need to be "joined", when one of the curtain walls is offset, it will gradually "radiate" to the curtain wall structures in other positions and "amplify" the degree of offset. The following technical solution is proposed:

[0030] Reference Figures 1 to 6 In this embodiment, a self-locking installation structure for an assembled building curtain wall includes a curtain wall body 1, which is equidistantly arranged along a linear direction, a central connection component is arranged on the central area of ​​the curtain wall body 1 in a plurality of adjacent positions, and a decorative component is arranged at the gap between the curtain wall bodies 1 in two adjacent positions;

[0031] The decorative component is composed of a decorative plate 2, a directional plug plate 4 and a bidirectional spring frame 5, and the central connection component includes a fixed stud 3, a directional screw sleeve 7, an expansion stud 12 and a movable cone plate 8. The fixed stud 3 passes through the directional screw sleeve 7 downward, and the lower end of the fixed stud 3 is threadedly connected to the expansion stud 12. The movable cone plate 8 is installed at the outer position of the directional screw sleeve 7, and the movable cone plate 8 is arranged in a circular array along the center point of the directional screw sleeve 7. An outer expansion wheel 16 corresponding to the movable cone plate 8 is rotatably installed in the fixed stud 3;

[0032] A connecting pin 14 is installed on the outer wall of the outer expansion wheel 16, and connecting column pins 6 corresponding to the connecting pin 14 are arranged at both ends of the bidirectional spring frame 5. The bidirectional spring frame 5 is parallel to the length direction or width direction of the curtain wall body 1, and the bidirectional spring frame 5 is composed of two arch frames. The middle end of the arch frame is in a curved arch shape along the direction close to the curtain wall body 1. The directional plug plate 4 is arranged at the inner position of the bidirectional spring frame 5, the decorative plate 2 is located on the upper side of the directional plug plate 4 and is fixedly connected to the directional plug plate 4, and notches corresponding to the fixing studs 3 are opened at both ends of the decorative plate 2.

[0033] Working principle: The operation process of conventional curtain walls is mainly to install them on aluminum frames through the connection relationship between high-strength studs and expansion studs. However, the present invention improves the connection relationship between high-strength studs and expansion studs, and the other structural parts when the curtain wall body is installed are not explained in detail. Specifically, the directional screw sleeve 7 and the fixed stud 3 are explained. The expansion stud 12 is directly nailed into the wall. When the fixed stud 3 is drilled into the expansion stud 12, it tends to move downward. The lower end of the high-strength spring 11 is arranged on the wall, and the other end is arranged on the lower side of the connecting column 10. In this process, the directional screw sleeve 7 is supported by the connecting column 10 and the high-strength spring 11 and maintains a relatively unchanged position. However, when the outer expansion wheel 16 moves to the lower side of the corresponding movable cone plate 8, the outer expansion wheel 16 is deformed outward, thereby providing a thrust along the length direction of the bidirectional spring frame 5. Figure 2 It is explained that when the bidirectional spring frame 5 is subjected to thrust, due to its structural and appearance characteristics, the middle end portion of the bidirectional spring frame 5 expands toward both sides of the outside, thereby also providing thrust to the two curtain wall bodies 1, the purpose of which is to preliminarily locate the installation position of the curtain wall body 1 and perform simple position correction.

[0034] Embodiment 2:

[0035] Explanation of the installation method of fixed studs and expansion screw sleeves:

[0036] A connecting column 10 is arranged at the lower side of the directional screw sleeve 7 corresponding to the fixing stud 3, and a supporting foot corresponding to the curtain wall body 1 is extended from the connecting column 10, and a supporting rubber plate 9 corresponding to the curtain wall body 1 is installed on each supporting foot. A high-strength spring 11 is arranged at the middle part of the fixing stud 3 corresponding to the connecting column 10 and the expansion screw sleeve 12.

[0037] Solution Description: Refer to Figure 4 To illustrate, and in combination with the conventional curtain wall construction method, the connecting column 10 is connected to the supporting rubber plate 9 through a plurality of legs, the purpose of which is to support the curtain wall body 1 from the lower side thereof through the supporting rubber plate 9, and each supporting rubber plate 9 can be moved synchronously by the extrusion of the directional screw sleeve 7, thereby ensuring that the curtain wall bodies 1 at every four adjacent positions are in a synchronous moving state, ensuring that the horizontality of the curtain wall bodies 1 at every four adjacent positions is in a relatively balanced state, and the supporting rubber plate 9 is essentially not a structure for fixing the curtain wall body 1, but is used to ensure the horizontality of each curtain wall body 1.

[0038] Embodiment 3: Combining Embodiment 1 and Embodiment 2, the following modular design is proposed:

[0039] The upper end of the movable cone plate 8 is installed on the directional screw sleeve 7, and the inner diameter of the movable cone plate 8 decreases from top to bottom. The inner wall of the movable cone plate 8 is provided with a directional groove 13 corresponding to the outer expansion wheel 16. The connecting bayonet 14 and the connecting column pin 6 are both provided with bevels on the outer wall positions close to each other, and the bevel directions of the connecting bayonet 14 and the connecting column pin 6 are set in opposite states. The outer wall position of the directional screw sleeve 7 is provided with a connecting slot 15 corresponding to the curtain wall body 1, and after the curtain wall body 1 is spliced, the decorative plate 2 therein plays a decorative role, but the key is to block the gap position between each curtain wall body 1, and notches are provided at both ends, which are mainly used to cooperate with the fixing studs 3. After the fixing studs 3 are rotated to the specified position, the decorative plate 2 can also be completely fixed to the curtain wall body 1 by the fixing studs 3.

[0040] Program Description: Figure 1 and Figure 2 In the construction method of each curtain wall body 1, each curtain wall body 1 is arranged in a linear direction, so that a central connection component is set at the center point of the curtain wall body 1 in four adjacent positions, and the purpose is that one central connection component can be responsible for trimming the curtain wall bodies 1 in four adjacent positions. More specifically, it is described as follows: combined with Figure 2 and Figure 4 It can be understood that four bidirectional spring frames 5 are connected to one directional screw sleeve 7, so that the fixing stud 3 and the directional screw sleeve 7 can provide thrust to the four bidirectional spring frames 5, and the specific description is as follows:

[0041] S1: Because the expansion screw sleeve 12 is installed in the wall, and the connecting column 10 and the directional screw sleeve 7 are supported by the high-strength spring 11, each supporting rubber plate 9 is used to simply support the curtain wall body 1, but when the fixed stud 3 continues to drill into the expansion screw sleeve 12, it will show a downward movement trend. During this process, the directional screw sleeve 7 maintains a relatively balanced state, and when the directional screw sleeve 7 is difficult to continue to move downward, the external expansion wheel 16 starts to squeeze the movable cone plate 8;

[0042] S2: In order to ensure that the movable cone plate 8 can be deformed freely, firstly, the inner diameter of the movable cone plate 8 is limited to decrease from top to bottom, and the directional groove 13 therein is to ensure that the movable cone plate 8 can be deformed, and to ensure that the upper end of the movable cone plate 8 is installed on the upper side of the directional screw sleeve 7, and it is also necessary to ensure the position stability of the directional screw sleeve 7 relative to the curtain wall body 1, specifically, the corner position of each curtain wall body 1 is just stuck in the connecting slot 15, and when the directional screw sleeve 7 shows a downward movement trend, the position of the directional screw sleeve 7 will not change at all;

[0043] S3: Reference Figure 3 , Figure 4 and Figure 5, because the deformation track of each movable cone plate 8 presents an arc, but the bidirectional spring frame 5 only needs to maintain a completely horizontal force, so it is necessary to ensure that the directional plug plate 4 is used to simply support and guide the bidirectional spring frame 5 from the inside, and then the decorative plate 2 is used to provide downward pressure on the entire bidirectional spring frame 5, so as to ensure that the bidirectional spring frame 5 can only be subjected to horizontal thrust along the length direction or width direction of the curtain wall body 1;

[0044] S4: It should be noted that in the overall curtain wall construction operation, multiple curtain wall bodies 1 are included. Figure 2 For example, one of the two-way spring frames 5 can receive the thrust generated by the corresponding movable cone plate 8 at one end, but the other end of the two-way spring frame 5 will also receive the thrust generated by the movable cone plate 8 at another position. Therefore, when multiple curtain wall bodies 1 are modularly spliced, when the fixing studs 3 move downward to the maximum distance, the degree of bending deformation of the movable cone plate 8 outward is in a relatively constant state, and the thrust received by the two-way spring frame 5 is also in a constant state. Therefore, the deformation degree of the two-way spring frame 5 is relatively constant. It can be further understood that: each of the four sides of the curtain wall body 1 will receive the thrust from the two-way spring frame 5, and the direction of the thrust will point to the center point of the curtain wall body 1.

[0045] In summary: In the construction of the curtain wall, based on four curtain wall bodies, a central connection component is set at the center point area. The central connection component is improved based on conventional studs and expansion screws. Its essence is to use the fixed studs to rotate downward and cooperate with the outer expansion wheel to deform outward, so as to provide pressure to the two-way spring frame at the gap of each curtain wall body, so that the two-way spring frame expands in the linear direction pointing to the curtain wall body, thereby squeezing the curtain wall body. The purpose is to make each curtain wall body fit more closely and move, so as to ensure the installation position of each curtain wall body. The overall structure is a modular design, and the pressure of the curtain wall bodies at each adjacent position is used to achieve the position during the installation process.
