Description

Technical Field

[0001] The utility model relates to the field of glass curtain walls, and particularly to a glass curtain wall skeleton structure. Background Art

[0002] Curtain wall buildings are a common form in modern architectural design, which can show an image with a strong sense of modernity and technology. It can achieve large-area glass curtain walls, making the building appearance transparent and bright, giving people a feeling of openness and lightness. Curtain wall buildings mainly include glass curtain walls, stone curtain walls and aluminum plate curtain walls. In the glass curtain wall structure, the skeleton structure of the curtain wall needs to be installed first, and the glass is installed on the skeleton structure. The skeleton structure is mainly composed of horizontal keels and vertical keels. Two adjacent vertical keels need to be butt-jointed through core inserts at the connection to ensure the consistency of the upper and lower vertical keels. However, curtain wall buildings are not as regular as conventional concrete building structures, and curtain wall buildings have various shapes. When vertical keels of different sizes are used in the upper structure and the lower structure of the curtain wall structure, how to connect the keels with different cross-sections in the upper and lower structures firmly and be able to ensure accurate positioning becomes a technical difficulty in construction. For this reason, this application proposes a glass curtain wall skeleton structure to solve the above problems. Content of the Utility Model

[0003] In view of the existing problems, the utility model provides a glass curtain wall skeleton structure, which can effectively solve the problems raised in the background art.

[0004] To solve the above problems, the utility model adopts the following technical solutions:

[0005] A glass curtain wall skeleton structure includes a concrete beam, vertical keels and horizontal keels. The horizontal keels are welded between two adjacent vertical keels. The vertical keels include lower vertical keels and upper vertical keels with different cross-sectional dimensions. An irregular core insert is provided at the butt-joint of the lower vertical keel and the upper vertical keel. The irregular core insert includes a lower core insert and an upper core insert. The lower core insert and the upper core insert are welded and fixed. The lower core insert is inserted into the lower vertical keel, and the upper core insert is inserted into the upper vertical keel.

[0008] As a further solution of the present utility model: both the upper insert core and the lower insert core are rectangular structures, and two adjacent side surfaces of the upper insert core and the lower insert core are arranged staggeredly.

[0009] As a further solution of the present utility model: the two adjacent and staggered side surfaces of the upper insert core and the lower insert core are correspondingly arranged with the side surfaces of the lower vertical keel and the upper vertical keel that are flush.

[0010] As a further solution of the present utility model: a sealing plate is welded inside one end surface of the upper insert core close to the lower insert core, and the joint part of the lower insert core and the upper insert core is welded.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Taking a stadium as an example, the present invention will be specifically described. In the upper and lower structures of the stadium, the sizes of the vertical keels selected are inconsistent. Among them, the size of the upper vertical keel is 200x100x8mm, and the size of the lower vertical keel is 120x80x4mm. A glass curtain wall and window sashes need to be installed between the vertical keels. When using traditional connectors for connection, a step will be formed at the junction of the upper vertical keel and the lower vertical keel, and the positioning is not firm, which increases the difficulty for the subsequent installation of glass and window sashes. Therefore, the present invention adds a special-shaped core insert to position and connect the upper and lower vertical keels, ensuring the positioning accuracy of the upper and lower vertical keels and also ensuring the flatness of one side of the keel, which is more convenient for the installation of window sashes and glass.

[0021] The following will be combined with Figures 1 to 5 Specifically illustrate this embodiment. This embodiment provides a glass curtain wall skeleton structure, which includes a concrete beam 1, vertical keels, and horizontal keels 2. The horizontal keels 2 are welded between adjacent two vertical keels. The vertical keels include lower vertical keels 3 and upper vertical keels 4 with different cross-sectional dimensions. A special-shaped core insert 5 is provided at the butt joint of the lower vertical keel 3 and the upper vertical keel 4. The special-shaped core insert 5 includes a lower core insert 51 and an upper core insert 52. The lower core insert 51 and the upper core insert 52 are welded and fixed. The lower core insert 51 is inserted into the lower vertical keel 3, and the upper core insert 52 is inserted into the upper vertical keel 4. The lower vertical keel 3 and the upper vertical keel 4 are flush on two adjacent sides.

[0022] In this embodiment, the cross-sectional dimension of the lower vertical keel 3 is smaller than that of the upper vertical keel 4. And two strip holes 53 are provided on the lower core insert 51. A channel steel adapter 7 is fixed on the concrete beam 1 through a buried part 6. The channel steel adapter is connected to the lower core insert 51 by bolts, and the bolts pass through the strip holes 53, which is used to fix the lower core insert 51 on the lower vertical keel 3 and at the same time can fixedly connect the lower vertical keel 3 and the concrete beam 1. Since the size of the lower vertical keel 3 is smaller than that of the upper vertical keel 4, therefore, the size of the lower core insert 51 is also smaller than that of the upper core insert 52. Thus, the lower core insert 51 can support the upper vertical keel 4. It is worth noting that the upper vertical keel 4 and the lower vertical keel 3 can also be connected to the building structure through the channel steel adapter 7 at other positions to achieve the purpose of fixation.

[0023] The following specifically illustrates the structure of the special-shaped core insert 5. As Figures 3 - 5As shown, the upper core 52 and the lower core 51 in the special-shaped core are both rectangular structures. Specifically, the upper core 52 and the lower core 51 are both rectangular structures composed of two side panels 8 and two end panels 9. The side panels 8 are welded to the end panels 9, and both sides of the end panels 9 extend out of the side panels 8 on the corresponding sides. The extended parts of the ends abut against the inner walls of the upper vertical keels 4 or the lower vertical keels 3 to achieve the positioning effect and prevent the vertical keels from shaking.

[0024] Since the sizes of the lower vertical keel 3 and the upper vertical keel 4 are inconsistent, there is also a difference in wall thickness, which is generally 2-4 mm. In order to ensure that the lower vertical keel 3 and the upper vertical keel 4 are connected through the special-shaped insert 5 to keep the two side surfaces flush, the upper insert 52 and the lower insert 51 are staggered. In this example, a certain distance is left between the outer side surface of the end plate 9 of the lower insert 51 and the outer side surface of the end plate 9 of the lower insert 51, and a certain distance is also left between the side plates 8. The specific length of the staggered distance depends on the size of the lower vertical keel 3 and the upper vertical keel 4. The size of the vertical keel 4 is determined. In this example, the upper core 52 and the end plate 9 of the lower core 51 are staggered by 7mm, the outer side of the side plate 8 on the upper core 52 and the end of the end plate 9 of the lower core 51 are staggered by 11mm, and the two adjacent staggered sides of the upper core 52 and the lower core 51 are arranged correspondingly to the sides flush with the lower vertical keel 3 and the upper vertical keel 4, so that it can be ensured that after the lower vertical keel 3 and the upper vertical keel 4 are inserted and positioned by the special-shaped core piece 5, the two adjacent sides of the lower vertical keel 3 and the upper vertical keel 4 are in the same plane. And a blocking plate 54 is welded on the inner side of one end face of the upper core 52 close to the lower core 51, and the lower core 51 and the upper core 52 are welded at the intersection. The blocking plate 54 is used to achieve the stable support of the lower core pull to the upper core 52 to avoid eccentric force.

[0025] The working principle of the utility model is: the upper vertical keel 4 and the lower vertical keel 3 of different cross-sectional sizes are inserted and positioned by the special-shaped insert piece 5, so as to improve the positioning accuracy, ensure the connection stability of the upper and lower vertical keels, improve the installation efficiency, speed up the construction progress, and at the same time, the two adjacent side surfaces of the upper vertical keel 4 and the lower vertical keel 3 are flush, so that the flatness of the glass is ensured when installing the glass, and at the same time, it is ensured that one side of the glass or the window is on the same straight line in the vertical direction, so as to improve the aesthetic appearance of the curtain wall structure.
