Description

Technical Field

[0001] This utility model belongs to the field of curtain wall installation technology, and in particular relates to a curtain wall hidden frame connection structure. Background Technology

[0002] The main feature of a frameless glass curtain wall is that the glass is pre-attached to the glass frame using structural adhesive, and then the entire glass frame (including the glass) is fixed to a grid composed of aluminum alloy components. Since both the glass frame and the aluminum alloy grid system are hidden behind the glass, the aluminum alloy frame is not visible from the outside, thus forming a large-area mirror-reflective screen curtain wall, making the overall building appearance simpler and more aesthetically pleasing.

[0003] However, the construction of fully concealed frame glass curtain walls is quite difficult. Current installation methods use corner brackets to fix the beams and columns, which are exposed. Therefore, different corner brackets are required for frames with different surface treatments, resulting in high production and installation costs. Furthermore, the above connection method requires auxiliary tools to temporarily fix the beams and columns, making the installation process cumbersome.

[0004] Chinese patent CN221346016U discloses a concealed frame curtain wall system. This system uses spring pins to connect the horizontal beams and vertical columns, improving installation convenience. Further connections between the horizontal beams and columns are achieved through connectors. However, in this system, the connectors are located on one side of the horizontal beam and vertical column, while the spring pins are on the other side. The horizontal beam's support comes from a single pin and connector, resulting in limited overall support and failing to improve the beam's lifting and support effect. Consequently, the connection between the horizontal beam and vertical column is also limited.

[0005] Therefore, a concealed frame connection structure for curtain walls is needed to improve the support for the horizontal beams and ensure the connection effect between the horizontal beams and the columns. Utility Model Content

[0006] The purpose of this utility model is to provide a hidden frame connection structure for curtain walls to solve the problems existing in the background technology.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A concealed frame connection structure for curtain walls includes columns, beams, and glass sub-frames. A connector is provided between the beams and columns. The connector includes an integrally connected baffle and a support strip. A hollow column is provided on one side of the top of the baffle, and an insert column is provided on one side of the connector. The columns have matching insertion holes corresponding to the positions of the hollow column and the insert column. The connector is inserted and fixedly connected to the columns. A spring pin is provided between the beams and the baffle, passing through the hollow column and extending into the column. The beams are placed on the support strip below, and a block is provided below the beams. The support strip has a slot corresponding to the position of the block, and the beams are inserted and fixedly connected to the support strip.

[0009] Furthermore, one side of the connector extends out of the column, and the support bar has a stud on the side extending out of the column. The stud is located near the glass sub-frame, and the glass sub-frame has a through hole corresponding to the position of the stud. The stud is inserted into the through hole of the glass sub-frame and fixed by a nut.

[0010] Furthermore, the two sets of spring pins are located on the top sides of the crossbeam, respectively.

[0011] Furthermore, the insert and slot have a dovetail-shaped structure.

[0012] Furthermore, the size of the baffle is adapted to the cross-sectional size of the crossbeam, and rubber pads are provided on both sides of the baffle.

[0013] Furthermore, the glass sub-frame is connected to the column via a pressure plate and bolts.

[0014] The beneficial effects of this utility model are:

[0015] 1) The crossbeam is fixed to the upper and lower sides by spring pins and blocks, which improves the connection strength. At the same time, the crossbeam is placed on the support bar, which improves the support and lifting effect of the crossbeam.

[0016] 2) The connectors are not only plugged into and fixed to the columns, but also connected to the glass sub-frames through studs and nuts, which further improves the connection strength of the connectors and enhances the support effect on the crossbeams. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See Figures 1-5 This utility model provides a technical solution:

[0025] like Figures 1-5 As shown, a curtain wall concealed frame connection structure includes a column 2, a beam 1 and a glass sub-frame 3, and a connector 4 is provided between the beam 1 and the column 2.

[0026] Connector 4 includes an integrally connected baffle 42 and support bar 41, such as Figure 5 As shown, the side view of the connector 4 is a square structure, and the size of the baffle 42 is adapted to the cross-sectional size of the beam 1, so that the beam 1 can be completely pressed against the baffle 42.

[0027] like Figures 1-3 As shown, hollow columns 44 are provided on both sides above the baffle 42, and insert posts 45 are provided on the same side of the support bar 41 corresponding to the hollow columns 44. The connector 4 is inserted into the corresponding insertion hole 21 of the column 2 through the hollow columns 44 and the insert posts 45 to complete the insertion and fixation. The insertion hole 21, hollow columns 44 and insert posts 45 can be quickly positioned and conveniently installed.

[0028] Furthermore, before installation, rubber pads 43 are provided on both sides of the baffle 42. The rubber pads 43 facilitate the connection between the beam 1 and the column 2, reduce wear on the contact surface, and reduce gaps to improve the sealing effect.

[0029] After the connector 4 is installed, the crossbeam 1 is inserted into the corresponding hollow column 44 via the spring pin 11, as follows: Figures 1-4As shown, the spring pins 11 are located on both sides of the top of the crossbeam 1. The size of the spring pins 11 is just enough to pass through the hollow column 44 and extend into the column 2. At the same time, the bottom of the crossbeam 1 is fixed by insertion through the insertion hole 21 and the slot 47.

[0030] The crossbeam 1 is fixed to the upper and lower sides by spring pins 11 and insert blocks 12, which improves the connection strength. At the same time, the crossbeam 1 is placed on the support bar 41, which improves the support and lifting effect of the crossbeam 1.

[0031] Furthermore, the plug 12 and the slot 47 adopt a dovetail structure, so that when the plug 12 is plugged into the slot 47, the plug 12 is difficult to fall out of the slot 47, thus improving the plugging strength.

[0032] After the crossbeam 1 and the column 2 are inserted and fixed, the glass sub-frame 3 is installed on the column 2. Since one side of the connector 4 extends out of the column 2, the support bar 41 is provided with a stud 46 on the side extending out of the column 2. The stud 46 is located on the side close to the glass sub-frame 3. The glass sub-frame 3 is provided with a through hole corresponding to the position of the stud 46. The stud 46 is inserted into the through hole of the glass sub-frame 3 and fixed by a nut.

[0033] Through the above technical solution, the connector 4 is not only inserted and fixed to the column 2, but also connected to the glass sub-frame 3 through the stud 46 and nut, which further improves the connection strength of the connector 4 and enhances the support effect on the crossbeam 1.

[0034] like Figures 1-2 As shown, after the glass sub-frame 3 is installed in place, the glass sub-frame 3 and the column 2 are locked and fixed by the pressure block 51 and the bolt 52. Since the connector 4 is fixed to the glass sub-frame 3, the connector 4, the glass sub-frame 3 and the column 2 are connected as one, which improves the overall strength and the support and connection effect of the beam 1.

[0035] After the glass sub-frame 3 and the column 2 are fixed, the outer glass 6 is connected to the glass sub-frame 3 with structural adhesive, thus completing the installation of the curtain wall. At this time, the glass sub-frame 3, the column 2 and the beam 1 are all located on one side of the glass 6.

[0036] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
