Description

Technical Field

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

[0002] When connecting the concave-shaped keels, connectors with various structures are required for fixation, and the same is true in the fields of fireproof curtain walls, glass partitions, etc. Taking the fireproof curtain wall as an example, there are longitudinal beams (longitudinal keels) and cross beams (transverse keels). The connection methods of these two types of profiles are diverse. For example, the bottom end of the longitudinal beam is grounded, and the cross beam is connected to one or both sides of the longitudinal beam; or the bottom surface of the cross beam is grounded, and the bottom end of the longitudinal beam is connected to the top surface of the cross beam. These connection methods require various connectors with different structures. Workers need to carry a large number of connectors during on-site construction, and they also need to distinguish and place them in advance without omission, otherwise it will cause inconvenience during use.

[0003] Moreover, although the structures of these connectors are similar and the differences are not significant, there are many inconveniences during processing. Not only are corresponding raw materials with different structures required, but also the relevant processing equipment needs to be appropriately modified, making the processing process cumbersome and the cost difficult to reduce.

[0004] Therefore, a connector that can adapt to different connection postures between the longitudinal beam and the cross beam is needed to meet the installation requirements. It can not only facilitate the on-site assembly of workers, but also reduce the processing difficulty, improve the efficiency and reduce the cost at the same time. Summary of the Utility Model

[0005] The utility model provides a novel fireproof curtain wall connector to solve the technical problem that the existing connectors cannot be applied to different connection postures between the keels, making the connection between the longitudinal beam and the cross beam more convenient and rapid.

[0009] On one side of the other pair of opposite sides of the connection body, a recessed part is provided.

[0010] Further, each of the two connection areas includes a fixing hole.

[0011] Further, the fixing holes are concentrically corresponding.

[0012] Furthermore, each of the two connection regions further includes an operation hole.

[0013] Furthermore, the fixing holes and the operation holes on one of the side support portions correspond to the fixing holes and the operation holes on the other telescopic side support portion in a staggered manner.

[0014] Furthermore, an extension portion having the same orientation as the side support portion is provided at the concave bottom of the concave portion.

[0015] Furthermore, the extension length of the extension portion is greater than the extension length of the side support portion.

[0016] Furthermore, at least one mounting hole is provided on the connection body.

[0017] Furthermore, at least one fastening hole is provided on the extension portion.

[0018] Furthermore, the side support portion and the extension portion are both at right angles to the connection body.

[0019] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0020] The utility model can adapt to different connection postures between concave keels, whether the bottom end of the longitudinal beam is grounded and the cross beam is connected to one or both sides of the longitudinal beam; or, the bottom surface of the cross beam is grounded and the bottom end of the longitudinal beam is connected to the top surface of the cross beam; with this connector, different installation angles and positions can be adapted, and workers only need to carry one type of connector, making on-site construction more convenient and efficient.

[0040] To make the objectives, technical solutions and advantages of the present utility model clearer and more distinct, the present utility model will be further described in detail below with reference to the accompanying drawings Figures 1 to 10 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.

[0041] 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 therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0042] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" 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.

[0043] Refer to the attached Figure 1 to the attached Figure 10 In this regard, the embodiment of the present utility model provides a novel fireproof curtain wall connector, which includes a connection body 100, which is a rectangular steel plate-like structure. Of course, the specific shape needs to be adapted to the shape of the concave keel, such as square or rectangular. Its thickness is not specifically limited, as long as it can achieve the corresponding support strength.

[0044] On one pair of opposite sides of the connection body 100, side support portions (i.e., the left support portion 210 and the right support portion 220 in Figure 1 ) extending in the same side direction are respectively provided. In practice, the two side support portions are symmetrical structures, which is convenient for bending processing. The side support portions 210, 220 are at a right angle to the connection body 100 to adapt to the connection between profiles. The reason for setting two side support portions is to be able to achieve different installation positions and angles of the concave keel. If there is only one side with a side support portion, then it can only adapt to a certain position and angle, and the use will be limited, which also contradicts the technical problem to be solved.

[0045] On the left support portion 210 and the right support portion 220, connection areas arranged symmetrically (i.e., the left connection area 211 and the right connection area 221 in Figure 1 ) are respectively provided. This area is the installation position during connection.

[0046] Refer to Figure 7 , the end of the transverse keel 4 (i.e., the concave keel) is fixed on one side or both sides of the longitudinal keel 5.

[0047] Taking the fixation on one side as an example, it not only needs to be fixedly connected to the ground, but also to the longitudinal keel 5. By using one of the side support parts, the transverse keel 4 can be fixedly connected to the ground, and the fastener 6 used for the fixation is an expansion bolt. The connection body 100 is in contact with the longitudinal keel, and the fastener 6 used between them is a screw, so that a firm connection between the transverse keel and the longitudinal keel, as well as between the transverse keel and the ground can be achieved.

[0048] Taking the fixation on both sides as an example, only the mirror inversion of the present utility model is needed, that is, using the other side support part to achieve the above fixation effect.

[0049] Reference Figure 8 , and taking the bottom end of the longitudinal keel 5 fixed on the top surface of the transverse keel 4 as an example, only the connection body 100 needs to be attached to the top surface of the transverse keel 4 and fastened with a fastener 6 (such as a screw).

[0050] The above three connection methods can be achieved and used in combination with this connector. Generally speaking, it is to flip the connector at different angles. The traditional connectors are all separate structures to adapt to different installation positions and angles. After adopting the present utility model, the on-site construction is more convenient.

[0051] Certainly, a recess 110 is provided on one side of the other pair of opposite sides of the connection body 100. This recess 110 is to adapt to the recessed groove on the concave keel (i.e., the transverse keel). For details, reference can be made to Figure 9 and Figure 10 . In the actual use process of this connector, it is placed inside the end of the transverse keel, so the recess 110 can be adapted to it. At the same time, in this embodiment, in order to better achieve the fastening connection effect, an extension part 300 with the same orientation as the side support parts 210 and 220 is provided at the bottom of the recess 110. It can be seen from the figure that the width of the extension part is not greater than the width of the recess in the keel, so as not to interfere with the insertion between the two. The extension part 300 can play a limiting role on the transverse keel from the outside. Moreover, at least one fastening hole 301 is provided on the extension part 300, and the fastening connection between the two can be achieved by using fasteners 6 such as screws, further improving the firmness of the connection. In addition, the reason for making the extension length of the extension part 300 greater than the extension lengths of the side support parts 210 and 220 is to increase the limiting area as much as possible, to facilitate the installation of fasteners 6 from as many different positions as possible, and to facilitate the manual operation of workers, preventing interference from the longitudinal keel 5 and making the operation more convenient. The extension part 300 and the connection body 100 are also in right-angle correspondence.

[0052] In this embodiment, corresponding holes may also be provided on the connection body and the side support portion to facilitate the installation of the fastener 6. The number of holes can be increased or decreased according to actual needs.

[0053] For example, each of the left connection region 211 and the right connection region 221 includes a left fixing hole 2111 and a right fixing hole 2211. In addition, the left fixing hole 2111 and the right fixing hole 2211 may be concentrically corresponding, so as to facilitate installation and fastening from two directions.

[0054] Each of the left connection region 211 and the right connection region 221 further includes a left operation hole 2112 and a right operation hole 2212. The operation holes are provided to facilitate the fastening operation more conveniently and to increase more fastening positions. In actual use, the aperture of the operation hole can also be larger than that of the fixing hole, so that it is more convenient to put in the fastener or use a tool to reach in for fastening operation. Of course, the operation hole can also be placed at the edge of the side support portion and leave a notch (as shown in Figure 1 ), which can further improve the convenience of the fastening operation.

[0055] For example, referring to Figure 5 , when the fastener 6 needs to be installed in the right fixing hole 2211, the electric wrench can be inserted from the left operation hole 2112, which improves the convenience of the worker's operation. That is, the fixing hole 2111 and the operation hole 2112 on one of the side support portions 210 and the fixing hole 2211 and the operation hole 2212 on the other telescopic side support portion 220 are staggered and corresponding to each other. When the connector is reversed (such as the connectors on the left and right sides in Figure 7 ), fast and convenient fastening operations can be achieved in the case of staggered correspondence.

[0056] If at least one installation hole 101 is provided on the connection body 100, or holes at other different positions are provided. Correspondingly, more expansion bolts or screws can be installed, and the connection firmness is better. The diameter of the hole can be changed according to the actual situation.

[0057] Of course, not pre-setting any holes can also solve the corresponding technical problems, but it requires the worker to drill holes on site, which is somewhat inconvenient.

[0058] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0059] The utility model can adapt to different connection postures between concave keels, whether the bottom end of the longitudinal beam is grounded and the cross beam is connected to one side or both sides of the longitudinal beam; or, the bottom surface of the cross beam is grounded and the bottom end of the longitudinal beam is connected to the top surface of the cross beam; with the use of this connecting piece, it can adapt to different installation angles and positions, and workers only need to carry one kind of connecting piece, making on-site construction more convenient and efficient.

[0060] The connection body, side support part and extension part in the utility model are all integrally bent and formed, and processed in as many symmetrical ways as possible. The processing difficulty and processes are greatly simplified, and the difficulty of equipment transformation required is also low, improving work efficiency while reducing processing costs.

[0061] Although the utility model has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the 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 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.
