Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof curtain wall connectors, and particularly relates to a concave connector for a steel fireproof curtain wall. Background Art

[0002] In the existing fireproof curtain wall structure, in order to achieve the support strength, connectors must be used to firmly connect the longitudinal keels and the transverse keels. After being fastened, a layer of metal decorative panel is wrapped to cover the fastening connection part to achieve the purpose of decoration.

[0003] Although the above method can achieve the purposes of firm connection, no fasteners being exposed, and aesthetics, it requires more profiles, increasing unnecessary costs. Moreover, the shape of the connector is relatively complex, the processing process is inconvenient, and there are obvious exposed parts after installation, so an additional decorative panel is required to cover it, increasing unnecessary costs.

[0004] Secondly, the curtain wall structures in reality are not completely flat. There are certain undulating shapes on the outer facade of the curtain walls of some buildings, such as special-shaped curtain wall structures like outer arc-shaped curtain walls or inner arc-shaped curtain walls. Specifically, the longitudinal keel structure in the curtain wall remains unchanged, while the connecting end face of the transverse keel needs to have a certain cutting angle to adapt to the undulating angle structure of the curtain wall outer facade. After the transverse keel with a certain cutting angle at the end face, the existing connectors cannot be used.

[0005] Moreover, the cutting positions of the transverse keel end faces for such undulating-shaped curtain walls are completely different, and there are various structural requirements for the connectors. Therefore, the currently used connectors still need to be further improved and upgraded, so it is necessary to design a connector with a simpler structure and easier to use. Summary of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides a concave connector for a steel fireproof curtain wall, which can simplify the existing connector structure, thereby reducing the usage and cost of profiles, and at the same time is also applicable to curtain walls in the shape of outer arcs or inner arcs.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A concave connector for a steel fireproof curtain wall,

[0009] including a first connecting part that fits with the longitudinal keel, and a second connecting part that is fixedly arranged on one side of the first connecting part and fits with the transverse keel.

[0010] Furthermore, the second connecting part inclines towards the outdoor side or the indoor side.

[0011] Furthermore, at least one mounting hole facing the fitting direction is provided on each of the first connecting part and the second connecting part.

[0012] Furthermore, the length direction of the first connecting part corresponds to the length direction of the longitudinal keel.

[0013] Furthermore, the length direction of the second connecting part corresponds to the length direction of the transverse keel.

[0014] Furthermore, the mounting holes on the first connecting part are arranged near both ends in the length direction of the first connecting part.

[0015] Furthermore, the length of the second connecting part is greater than the length of the first connecting part.

[0016] Furthermore, the mounting holes on the second connecting part are arranged at one end away from the first connecting part.

[0017] Furthermore, both the first connecting part and the second connecting part are plate-like structures.

[0018] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0019] Compared with traditional connectors, the structure of the present utility model is qualitatively simplified. The first connecting part and the second connecting part in the form of plate-like structures are respectively fitted with the longitudinal keel and the transverse keel, and then fixed with screws or rivets, so as to achieve a stable connection effect. After the structure is simplified, it is easier to hide, and it is also placed in the groove on the inner side of the transverse keel. After the decorative strip is buckled, there are no exposed parts, and the whole is more beautiful.

[0020] In addition, the installation direction of traditional connectors is mostly in the up-and-down direction at both ends of the transverse keel, and workers need to bend down to work. Now the installation direction is in the horizontal direction, that is, the installation direction on the inner side and the outer side of the room, and it is more convenient for workers to operate.

[0037] Refer to the attached Figure 1 to the attached Figure 4 , and this embodiment is described by taking the outer arc structure of the curtain wall as an example.

[0038] A concave connector for a steel fireproof curtain wall includes a first connecting portion 100 that fits with a longitudinal keel 400. One side edge of the first connecting portion 100 is fixedly provided with a second connecting portion 200 that fits with a transverse keel 500. Both the first connecting portion 100 and the second connecting portion 200 are plate-like structures, and the overall shape and structure are greatly simplified compared with traditional connectors (for reference, see Figure 4 ).

[0039] Moreover, the second connecting portion 200 inclines towards the outdoor side or the indoor side. The reason for inclining towards the outdoor or indoor direction is to meet the requirements of the undulation of the curtain wall facade. That is to say, when a larger area is cut off from the indoor side direction of the connection end of the transverse keel, the transverse keel as a whole inclines towards the indoor side direction (for reference, see Figure 4 ), and the facade of the curtain wall has an outer arc structure.

[0040] The inclination direction and angle of the second connecting portion 200 need to be consistent with the inclination angle and reverse direction of the transverse profile, so as to fixedly connect both ends of the transverse keel to the longitudinal keel.

[0041] Refer to Figure 1 and Figure 2 , and mounting holes 300 that penetrate in the thickness direction thereof, that is, towards the fitting direction, are respectively provided on the first connecting portion 100 and the second connecting portion 200. For better stable connection, usually two mounting holes 300 are provided to facilitate the penetration and fastening connection of screws or rivets.

[0042] In this embodiment, in order to achieve a better connection effect, the length direction of the first connecting portion 100 corresponds to the length direction of the longitudinal keel 400, that is, their length directions (or axial directions) are the same, which can provide good stability. The length direction of the second connecting portion 200 corresponds to the length direction of the transverse keel 500, that is, their length directions (or axial directions) are the same, which can also provide good stability, and the connection is more firm and not easily deformed.

[0043] In actual operation, for the convenience of manual operation by workers, the mounting holes 300 on the first connecting part 100 are arranged near both ends in the length direction of the first connecting part 100, so that when workers perform the fastening operation, they will not be blocked by the second connecting part 200, and the operation is more convenient.

[0044] Correspondingly, when the second connecting part inclines towards the indoor direction, the length of the second connecting part 200 is greater than the length of the first connecting part 100. Moreover, the mounting holes 300 on the second connecting part 200 are arranged at one end away from the first connecting part 100. In this way, when workers perform the fastening operation, they will not be affected by the block of the first connecting part 100, and workers can perform the fastening operation in a horizontal direction while standing indoors. If this structure is not adopted, workers are likely to be blocked by the first connecting part 100 or the longitudinal keel 400 during the fastening operation, making it difficult to fasten. Embodiment Two

[0045] Refer to Atta Figure 5 to Atta Figure 8 This embodiment is described by taking the inner arc structure of the curtain wall as an example.

[0046] The same parts as those in Embodiment One will not be elaborated here.

[0047] Refer to Figure 8 When a larger area is cut off from the outdoor side direction of the connection end of the transverse keel, the transverse keel is inclined as a whole towards the outdoor side direction, and the outer facade of the curtain wall presents an inner arc structure.

[0048] Since the second connecting part 200 inclines towards the outdoor side direction, it will not affect the mutual influence of the mounting holes 300 of the first connecting part 100, and the corresponding operation angles for workers during the fastening operation are larger, without mutual interference or blockage. Embodiment Three

[0049] Refer to Atta Figure 9 to Atta Figure 11 This embodiment is described by taking the structure with a flat outer facade of the curtain wall as an example.

[0050] The same parts as those in Embodiment One will not be elaborated here.

[0051] In this embodiment, the connection part two 200 and the connection part one 100 are connected at a right angle, that is, the horizontal keel and the vertical keel are connected at a right angle. In this way, the outer facade of the curtain wall is a flat surface without undulating structures. In addition, the surface of the horizontal keel facing the indoor side is the installation surface. Workers attach the connection part one 100 to the vertical keel and the connection part two 200 to the horizontal keel, and then fasten and connect them with screws or rivets. Moreover, the installation direction also conforms to the horizontal fastening operation of workers in a standing posture, rather than the traditional installation angle of bending down from bottom to top. The connecting piece structure of the present utility model is also simpler. During installation, the structural members are in an upright posture as a whole, which can play a stable supporting effect, and the horizontal keel can be firmly fixed on the vertical keel.

[0052] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0053] Compared with the traditional connecting piece, the structure of the present utility model is qualitatively simplified. The connection part one and the connection part two in the form of plate structures are respectively attached to the vertical keel and the horizontal keel, and then fixed with screws or rivets, so as to achieve a stable connection effect. After the structure is simplified, it is easier to hide, and it is placed in the groove on the indoor side of the horizontal keel. After the decorative strip is buckled, there are no exposed parts, and the whole is more beautiful.

[0054] In addition, the installation direction of the traditional connecting piece is mostly in the up and down direction at both ends of the horizontal keel, and workers need to bend down to work. Now the installation direction is in the front and back direction of the horizontal keel, that is, the installation direction of the indoor side and the outdoor side, and the operation of workers is more convenient.

[0055] Principle description:

[0056] In the inner arc curtain wall structure, it is necessary to cut at a certain angle on the outdoor side direction of the connection end of the horizontal keel 500, which causes the horizontal keel 500 to deviate towards the outdoor side direction, and the outer facade of the curtain wall will present an inner arc undulating structure (refer to Figure 8 )

[0057] In the outer arc curtain wall structure, it is necessary to cut at a certain angle on the indoor side direction of the connection end of the horizontal keel 500, which causes the horizontal keel 500 to deviate towards the indoor side direction, and the outer facade of the curtain wall will present an outer arc undulating structure (refer to Figure 4 )

[0058] In the curtain wall structure with a flat outer facade, both ends of the horizontal keel 500 are in a flat right-angle cutting shape, which can achieve a right-angle butt joint with the vertical keel, and the connection part one 100 and the connection part two 200 are also at a right angle, so that the outer facade is in a flat plane state.

[0059] In the present utility model, the inclination angle of the second connecting part 200 can be changed according to actual needs, such as common 90-degree angles, 45-degree angles, 135-degree angles or other angles. That is, the arc angle of the outer facade of the curtain wall needs to correspond to the inclination angle of the second connecting part 200.

[0060] The concave-shaped connecting piece of the present utility model has been greatly simplified compared with the structure of traditional connecting pieces, with a smaller volume and more convenient use. In particular, the installation process is more convenient, and workers only need to perform simple fastening operations. Moreover, in order to adapt to the undulating structures of different angles of the curtain wall, the angle processing of the second connecting part 200 is also more convenient, and the production cost is lower. After installation, the concave-shaped connecting piece of the present utility model is placed in the groove 501 on the indoor side of the horizontal keel 500, and a decorative strip can be inserted into the groove 501 to hide the concave-shaped connecting piece, making the overall appearance unified and beautiful. During maintenance, only the decorative strip needs to be removed to expose the concave-shaped connecting piece, which is convenient for replacement and repair.

[0061] Although the present utility model has been described above with reference to embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
