Description

Technical Field

[0001] The utility model relates to the technical field of fireproof curtain walls, and particularly relates to a horizontal profile of a steel fireproof curtain wall. Background Technique

[0002] In the profiles of building curtain walls, the longitudinal profiles are fixed in the vertical direction, and the horizontal profiles are fixed in the horizontal direction, both of which are used to support and fix the glass. The two ends of the horizontal profile need to be fixedly connected to the longitudinal profile, and there are many drawbacks in the currently used connectors:

[0003] First of all, the distance between the longitudinal profiles is the length dimension of the horizontal profile. In order to achieve a firm connection between the two, it is necessary to first install a connector with a relatively complex structure at a suitable position, and then insert the end of the horizontal profile onto this connector and fasten it with screws. Although this method can achieve a good connection effect, the installation process is inconvenient, and the screws are still exposed and not beautiful. This kind of horizontal profile can only be applied to the curtain wall with a flat outer facade, and cannot be applied to the curtain wall with a fluctuating structure on the outer facade. Once the end of the horizontal profile is not a right angle but has a certain angle of inclination structure, it cannot adapt to the connector, and the connector with a complex structure needs to be modified.

[0004] Secondly, some connectors have a simple structure, are easy to install, and are also suitable for curtain walls with a fluctuating structure on the outer facade, and have low requirements for the structure of the horizontal profile. However, they need to be installed outside the longitudinal profile and / or the horizontal profile, that is to say, not only the screws are exposed, but the connectors are also in an exposed state, which is very unsightly.

[0005] Thirdly, the traditional way of fixing the horizontal profile is to use connectors to tightly connect it with the longitudinal keel in the up and down directions at both ends of the horizontal profile. The angles in the up and down directions bring inconvenience to manual operation by workers, and it is necessary to frequently bend down to manually fasten from bottom to top, which is laborious and not handy.

[0006] Therefore, it is necessary to design a new type of horizontal profile with a simple structure and easy to install, which not only has no exposed connectors, but also can adapt to the curtain wall with a certain angle of fluctuation on the outer facade, bringing more convenience to the installation and use of the curtain wall. Content of the Utility Model

[0007] The utility model provides a horizontal profile of a steel fireproof curtain wall to solve the problems raised in the above background technique.

[0008] To solve the above technical problems, the technical solution adopted by the utility model is:

[0009] A horizontal profile of a steel fireproof curtain wall includes a profile body extending in the length direction, and a convex portion for carrying glass is provided on one side surface of the profile body facing the outdoor direction;

[0010] On one side of the profile body facing the indoor direction, there is a positioning groove arranged along its length direction, and the positioning groove penetrates through both ends of the profile body in the length direction.

[0011] Preferably, there is also a decorative strip adapted to be inserted into the positioning groove.

[0012] Preferably, on one side of the profile body facing the outdoor direction, there are rubber strip installation grooves symmetrically arranged on both sides of the protruding part.

[0013] Preferably, the end face of the positioning groove is square.

[0014] Due to the adoption of the above technical solution, the technical progress of the present utility model compared with the prior art is:

[0015] One side of the profile body facing the indoor direction is no longer a flat surface, but is provided with a positioning groove, and the end face of the positioning groove is square, which can be adapted to place a decorative strip. After inserting the decorative strip, one side of the profile body facing the indoor direction becomes a flat surface, meeting the requirement of aesthetics.

[0016] The positioning groove can be used to hold the connecting piece. That is to say, one side of the connecting piece fits the longitudinal profile, and the other side fits into this positioning groove, realizing a hidden connection method. After putting the decorative strip, it can just cover the connecting piece, and there are no exposed parts outside. When maintaining and disassembling, just take out the decorative strip.

[0017] Importantly, the end of the transverse profile can be cut at any angle, rather than the traditional right-angle end structure. The connecting piece used with it is also more convenient and handy to install. Workers only need to align the position and tighten the screws. Brief Description of the Drawings

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following will further elaborate on the present utility model through the appended Figure 1 to the appended Figure 7 and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and do not limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0029] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] In this embodiment, a horizontal profile of a steel fireproof curtain wall is disclosed, which includes a profile body 100 extending in the length direction. Its end face is a common square structure. On one side of the profile body 100 facing the outdoor direction, there is a protruding portion 101 for carrying glass, that is, the bottom edge of the glass can be placed on this protruding portion 101 to achieve support.

[0032] On one side of the profile body 100 facing the indoor direction, there is a positioning groove 103 arranged along its length direction. This positioning groove 103 can be used to place a connecting piece 300. That is to say, the connecting piece 300 is placed in the positioning groove 103 in a concealed manner. Coupled with the fact that the opening of the positioning groove 103 faces the indoor side direction, during installation by workers, there is no need for complicated adjustment. Only the connecting piece 300 needs to be placed in the positioning groove 103 and the screw 400 tightened. Of course, the size of the connecting piece 300 should be smaller than the width of the positioning groove 103 to be able to be placed. Finally, a decorative strip 200 is installed for shielding, and the appearance will be flat and beautiful. The decorative strip 200 is also convenient for disassembly and installation, and there is no need for a destructive way to remove it during later maintenance. Refer to Figure 4 , the width of the positioning groove 103 is slightly smaller, and the size of the corresponding connecting piece 300 also becomes smaller, and the size of the insertion end of the used decorative strip 200 is also small, but the outer surface of the decorative strip 200 needs to be adapted to the width of the indoor side of the profile body 100.

[0033] For traditional horizontal profiles, in order to be beautiful when installing connecting pieces, the connecting pieces are mostly placed on the bottom surface of the horizontal profile, and workers still need to bend down to tighten the screws upward, which is very inconvenient.

[0034] In addition, the positioning groove 103 penetrates through both ends of the profile body 100 in the length direction and can be used regardless of the angle at which the end of the horizontal profile is cut.

[0035] For example, refer to Figure 5 , taking the inner arc curtain wall structure as an example, when cutting the end of the horizontal profile, more outdoor side parts need to be cut off so that the horizontal profile can be inclined towards the outdoor side direction. However, the positioning groove 103 on the indoor side of the horizontal profile is not affected by the cutting, and it is convenient for workers to install.

[0036] For example, refer to Figure 6 , taking the outer arc curtain wall structure as an example, when cutting the end of the horizontal profile, more indoor side parts need to be cut off so that the horizontal profile can be inclined towards the indoor side direction. However, the positioning groove 103 on the indoor side of the horizontal profile is also not affected by the cutting, and it is convenient for workers to install.

[0037] Importantly, affected by the improvement of the transverse profile structure, the required connecting piece structure is also simpler, more convenient for production and installation, and the installation efficiency is greatly improved. The installation of the connecting piece has been improved from the traditional way of workers bending down to install it in the up-and-down direction to the current way of workers standing to install it, which is more convenient and handy.

[0038] Preferably, on one side of the profile body 100 facing the outdoor direction, there are rubber strip installation grooves 102 symmetrically arranged on both sides of the protruding part 101, which can be used to clamp rubber strips, making the installation more convenient.

[0039] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0040] The side surface of the profile body facing the indoor direction is no longer a flat surface, but is provided with a positioning groove, and the end surface of the positioning groove is square, which can be adapted to fit a decorative strip. An arc-shaped protruding part can be arranged on the decorative strip or in the positioning groove for limiting and clamping, so as to improve the connection firmness between the decorative strip and the positioning groove. After inserting the decorative strip, the side surface of the profile body facing the indoor direction becomes a flat surface, meeting the requirement of flatness and beauty.

[0041] The positioning groove can be used to hold the connecting piece, that is, one side of the connecting piece fits the longitudinal profile, and the other side fits in this positioning groove, realizing a hidden connection method. After putting in the decorative strip, it can just cover the connecting piece, and there are no exposed parts outside. When maintaining, disassembling and assembling, just take out the decorative strip.

[0042] Importantly, the end of the transverse profile can be cut at any angle, rather than just the traditional right-angle structure at the end. The connecting piece used with it is also more convenient and handy during installation. Workers only need to align the position and tighten the screws. Since the side surface of the profile body 100 facing the indoor direction is provided with a positioning groove 103, it is convenient for workers to perform the connection and tightening operation in a horizontal state, rather than the traditional up-and-down tightening operation, which is more convenient and handy.

[0043] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and its components 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 embodiments disclosed by the present utility model can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
