Description

Technical Field

[0001] This utility model relates to the field of fireproof curtain wall technology, and in particular to a new type of steel fireproof curtain wall keel. Background Technology

[0002] In building curtain wall profiles, longitudinal profiles are fixed vertically, while transverse profiles are fixed horizontally, both used to support and fix the glass. The ends of the transverse profiles need to be fixedly connected to the longitudinal profiles. Chinese utility model patent CN223034284U discloses a steel fireproof curtain wall transverse profile that has good stable support and is also suitable for on-site installation.

[0003] However, after a period of application, there are still some drawbacks. For example, the protruding structure on the profile body is relatively simple, and the connection stability with the corner bracket is somewhat insufficient. Especially in windy weather, it will affect the overall wind pressure resistance of the curtain wall.

[0004] Secondly, the aforementioned patent involves installing screws at the ends of the protruding parts for fastening the connection with the corner brackets. However, this area is relatively flat, requiring workers to carefully check the position during installation, which is inconvenient. Moreover, the limiting effect on the screws and corner brackets is insufficient, which still affects the overall stability of the curtain wall. Utility Model Content

[0005] This utility model provides a novel steel fireproof curtain wall keel to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A novel steel fireproof curtain wall keel includes a profile body extending in the length direction, and the profile body has a protrusion for supporting glass on one side facing the outside. The protrusion has a recess on the side away from the profile body, and the recess extends through the length of the protrusion.

[0007] Preferably, the profile body has a positioning groove arranged along its length on one side facing the interior direction, and the positioning groove passes through both ends of the profile body along its length.

[0008] Preferably, a decorative strip is also provided to fit into the positioning groove.

[0009] Preferably, the profile body has symmetrically arranged adhesive strip mounting grooves on both sides of the protrusion on one side facing the outside.

[0010] Preferably, the end face of the positioning groove is square.

[0011] Preferably, the recessed portion is provided with a snap-fit ​​strip that is adapted to engage with it.

[0012] Due to the adoption of the above technical solution, the technological advancement of this utility model compared to the prior art is as follows: By setting recesses on the protrusions, the end face structure of the protrusions can be bent in multiple places, resulting in better overall load-bearing strength and tensile strength, thus improving the overall wind pressure resistance of the curtain wall.

[0013] The screws can be concealed, and workers can feel a clear restraining effect in the recessed area during installation, making screw installation convenient. The angle brackets and screws can bear force from all directions under the action of the recessed area, resulting in a more secure connection. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following is a summary description. Figure 1 To be continued Figure 6 The present invention will be further described in detail with reference to embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] This embodiment discloses a novel steel fireproof curtain wall keel, including a profile body 100 extending in the length direction, the end face of which is a common square structure. The profile body 100 has a protrusion 101 for supporting glass on one side facing the outside, that is, the bottom edge of the glass can be placed on this protrusion 101 for support.

[0020] The protrusion 101 has a recess 1011 on the side away from the profile body 100, and the recess 1011 extends through the length of the protrusion 101. This utility model is an integral extrusion molding.

[0021] The structure here can form multiple bends, thereby increasing the load-bearing strength. The recess 1011 can also hide the screws. The shape of the recess 1011 makes it easier for workers to install the screws. Afterwards, the recess 1011 can be sealed and covered with the fastener 1012 or sealant.

[0022] The profile body 100 has a positioning groove 103 extending along its length on one side facing the interior. This positioning groove 103 can accommodate the connector 300. In other words, the connector 300 is concealed within the positioning groove 103. Since the opening of the positioning groove 103 faces the interior, installation requires no complicated adjustments; workers simply insert the connector 300 into the positioning groove 103 and tighten the screws 400. Of course, the connector 300 must be smaller than the width of the positioning groove 103 to fit. Finally, a decorative strip 200 is installed to conceal it, resulting in a smooth and aesthetically pleasing appearance. The decorative strip 200 is also easy to install and remove, and can be maintained without destructive removal. (Reference) Figure 4 The width of the positioning groove 103 is slightly smaller, and the corresponding size of the connector 300 is also smaller. The size of the plug end of the trim strip 200 is also smaller, but the outer surface of the trim strip 200 needs to be adapted to the width of the interior side of the profile body 100.

[0023] For aesthetic reasons, when installing connectors on traditional horizontal profile keels, the connectors are often placed on the bottom of the horizontal profile keel. Workers then have to bend over and tighten the screws upwards, which is very inconvenient.

[0024] In addition, the positioning groove 103 extends through both ends of the profile body 100 along its length, and can be used regardless of the angle at which the ends of the transverse profile keel are cut.

[0025] For example, reference Figure 5 Taking the inner curved curtain wall structure as an example, when cutting the end of the horizontal profile keel, more of the outdoor side needs to be cut off so that the horizontal profile keel can tilt towards the outdoor side. However, the positioning groove 103 on the indoor side of the horizontal profile keel is not affected by the cutting, making it convenient for workers to install.

[0026] For example, reference Figure 6 Taking the external curved curtain wall structure as an example, when cutting the end of the horizontal profile keel, more of the indoor side needs to be cut off so that the horizontal profile keel can tilt towards the indoor side. The positioning groove 103 on the indoor side of the horizontal profile keel is not affected by the cutting, making it convenient for workers to install.

[0027] Importantly, due to the improved horizontal profile keel structure, the required connector structure is also simpler, making production and installation more convenient and significantly improving installation efficiency. The traditional method of workers bending over to install connectors vertically has been improved to workers installing connectors standing up, making the operation more convenient and efficient.

[0028] Preferably, the profile body 100 has symmetrically arranged adhesive strip mounting grooves 102 on both sides of the protrusion 101 on one side facing the outside, which can hold the adhesive strip and make installation more convenient.

[0029] Due to the adoption of the above technical solution, the technological advancement of this utility model compared to the prior art is as follows: By setting recesses on the protrusions, the end face structure of the protrusions can be bent in multiple places, resulting in better overall load-bearing strength and tensile strength, thus improving the overall wind pressure resistance of the curtain wall.

[0030] The screws can be concealed, and workers can feel a clear restraining effect in the recessed area during installation, making screw installation convenient. The angle brackets and screws can bear force from all directions under the action of the recessed area, resulting in a more secure connection.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
