Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall components, in particular to a curtain wall column and crossbeam connection structure. Background Art

[0002] In the curtain wall frame structure, the main components are beams and columns, which are spliced ​​together to form a frame for glass installation. Therefore, it is necessary to ensure that the connection between the beams and the columns has sufficient supporting capacity to ensure the stability of the glass in the frame.

[0003] When connecting the crossbeam and the column, a spring pin is often used as a connecting piece to connect the column and the crossbeam. However, the spring pin and the plug used with it cannot effectively maintain a tight connection between the crossbeam and the column, and the plug may be separated from the original position, resulting in looseness. At the same time, if the front end area of ​​the crossbeam and the column is not firmly fixed, the crossbeam is prone to tilt under the influence of the gravity of the subsequently installed glass, thereby causing the safety of the connection between the crossbeam and the column to be unable to be guaranteed. Utility Model Content

[0004] The purpose of the utility model is to provide a column-beam connection structure that effectively ensures the stability of curtain wall frame connection. To this end, the utility model adopts the following technical solutions:

[0005] A curtain wall column and crossbeam connection structure, a notch is provided on the inner wall of the crossbeam, a spring latch is provided in the notch, a limit hole is provided on the side of the column, a limit pedestal is provided on the pin column side end of the spring latch, the limit pedestal extends into the limit hole and is connected with the column by clamping; a column groove is provided on the outer side end surface of the column and the opposite room, a connecting piece is provided on the column groove, the connecting piece extends out in the lateral direction to the side of the column to set a limit end, and the limit end is inserted into the retaining wing of the crossbeam.

[0006] Furthermore: a locking section and a connecting section are respectively provided at two ends of the position limiting support platform along the transverse direction, and the diameter of the locking section is greater than the diameter of the connecting section.

[0007] Furthermore, the limiting hole is divided into a first hole section through which the locking section can pass and a second hole section through which only the connecting section can pass in its radial direction, and the first hole section and the second hole section are connected to each other.

[0008] Furthermore: a limited locking piece is connected between the connecting piece and the column groove.

[0009] Furthermore: a plug is also arranged in the slot of the spring latch.

[0010] Furthermore: a sealing layer is provided at the joint between the cross beam and the column.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model connects the crossbeam and the column by the cooperation of the spring latch and the connecting piece, thereby ensuring the connection stability after the crossbeam and the column are connected, and at the same time, improving the working efficiency when the crossbeam and the column are connected. The utility model limits the displacement of the crossbeam and the column by clamping the connecting piece in the column groove and inserting its limit end into the stop wing, thereby ensuring that the crossbeam will not be twisted, and avoiding accidents caused by unstable connection of the glass between the crossbeam and the column; at the same time, the spring latch and its limit bearing platform can make the connection of the spring latch more convenient and stable under the connection of the limit hole on the side of the column, and there is no situation where the connection between the crossbeam and the column fails after the spring latch shrinks.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] like Figure 1-4 As shown, this embodiment provides a curtain wall column-beam connection structure, a notch 11 is provided on the inner wall of the beam 1, a spring latch 3 is provided in the notch 11, a limiting hole 21 is provided on the side of the column 2, a limiting platform 34 is provided on the side end of the pin 32 of the spring latch 3, the limiting platform 34 extends into the limiting hole 21 and is connected with the column 2 by clamping; a column groove 22 is provided on the outer end surface of the column 2 relative to the room, a connecting piece 4 is provided on the column groove 22, the connecting piece 4 extends out of the column 2 in the lateral direction and a limiting end 41 is provided on the side, and the limiting end 41 is inserted into the retaining wing 12 of the beam 1.

[0020] like Figure 4As shown, the connecting piece 4 is in a concave shape, and the limiting end 41 is the protruding part of the connecting piece 4; a limiting locking member 5 is connected between the connecting piece 4 and the column groove 22. The displacement of the connecting piece 4 on the column 2 is limited by the cooperation between the limiting locking member 5 and the connecting piece 4 and the column groove 22, and at the same time, the connecting piece 4 can also control the front and rear displacement of the cross beam 1.

[0021] The limiting locking member 5 is a screw that connects the connecting piece 4 and the column 2 together.

[0022] like Figure 2-4 As shown, specifically, the two ends of the limit platform 34 in the transverse direction are respectively provided with a locking section and a connecting section, and the diameter of the locking section is larger than the diameter of the connecting section. In this way, the limit platform 34 is clamped on the column 2 by the abutment between the locking section and the column 2, so as to avoid the situation that the connection between the crossbeam and the column fails after the spring latch 3 is contracted;

[0023] The limiting hole 21 is divided into a first hole section 211 through which the locking section can pass and a second hole section 212 through which only the connecting section can pass in the radial direction, and the first hole section 211 is connected to the second hole section 212. At the same time, the diameter of the locking section of the limiting support 34 is slightly smaller than the aperture of the first hole section 211, and the diameter of the connecting section is slightly smaller than the aperture of the second hole section 212, so that the limiting support 34 can pass through the limiting hole 21.

[0024] Specifically, the spring latch 3 is further provided with a plug 33 in the slot 11 , and a spring 31 is provided between the plug 33 and the pin 32 .

[0025] Specifically, a sealing layer 6 filled with sealant is provided at the joint between the cross beam 1 and the column 2 .

[0026] See also Figure 1-4 When the curtain wall column beam connection structure is connected, the specific contents are as follows:

[0027] During the construction of the connection between the crossbeam 1 and the column 2, the worker puts the spring latch 3 into the notch 11 of the crossbeam 1, and puts in the plug 33, the spring 31 and the latch 32 in sequence. The limit bearing platform 34 of the installed spring latch 9 needs to protrude a certain length from the crossbeam 1, so that it can extend into the first hole section 211 through the limit bearing platform 34, until the connecting section of the limit bearing platform 34 enters the position of the first hole section 211. At this point, the worker pushes the crossbeam 1 backward so that the connecting section of the limit bearing platform 34 enters the second hole section 212, so that the spring latch 9 can be quickly and effectively stuck on the column 2 without complicated installation means. Then put the connecting piece 4 into the column groove 22, and insert the limit end 41 into the stop wing 12, and fix the connecting piece 4 on the column 2 through the limit locking member 5.

[0028] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiments can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
