Description

Technical Field

[0001] The invention relates to the technical field of glass curtain walls, in particular to a canopy upper tie rod full-glass curtain wall node and an installation method thereof. Background Art

[0002] In modern architectural design, all-glass curtain walls are favored for their beauty and transparency. However, when applied to large-span structures, traditional all-glass curtain walls face many technical challenges, especially in canopy design. Large-span canopies need to withstand large wind pressure and deadweight, while also ensuring the stability and durability of the structure. Canopies supported by traditional steel structures are prone to deflection and deformation in large-span applications, affecting structural stability. These issues not only involve material selection and structural design, but also include the application of construction technology and considerations for later maintenance.

[0003] For example, the structural design of a large-span glass curtain wall needs to take into account the brittle characteristics of glass to ensure safety performance under wind loads and earthquakes. The connection method between the glass panel and the glass rib, the design of the connector, and the overall stability of the glass rib are all key issues in the design. In addition, the construction technology of the large-span steel structure canopy is also a challenge, and appropriate construction methods need to be adopted, such as high-altitude bulk method, ground hoisting method, overall lifting method, etc., to ensure the accuracy and operability of the construction.

[0006] Furthermore, a steel beam is provided at the connection node between the vertical keel and the steel column, and both ends of the steel beam are respectively connected to the connection nodes between adjacent vertical keels and the steel columns. Curtain wall glass is fixedly installed on adjacent steel columns, and the top of the curtain wall glass is connected to the steel beam by silicone structural sealant.

[0007] Furthermore, the top edge of the curtain wall glass is provided with a top arc and a concave arc, that is, it includes top arc glass and concave arc glass, the arc is 1 / 1600 of the length of the top edge of the curtain wall glass, and the top arc glass and concave arc glass are arranged in an alternating manner.

[0008] Furthermore, the stress inclined tie rod includes an articulated section and an adjusting section. There are two articulated sections, one end of which is provided with an articulated ear, and the other end is provided with a four-hole flange. Both ends of the adjusting section are provided with four-hole flanges. The articulated ears of the two articulated sections are respectively articulated to the steel columns and the transverse keels, and the two ends of the adjusting section are respectively connected to the four-hole flanges of the two articulated sections.

[0009] Furthermore, the adjustment section includes two screw rods and an adjustment ring, the adjustment rod includes two connecting rods parallel to each other and nuts respectively arranged at both ends of the two connecting rods, the two nuts are hinged to the two connecting rods, one end of the two screw rods is connected to a four-hole flange, and the other end is threadedly connected to the two nuts respectively, the threads of the two nuts are mutually reverse threads, and anti-slip rings are arranged on the parts of the two screw rods extending into the interior of the adjustment ring, and the anti-slip rings are threadedly connected to the screw rods.

[0010] The invention also includes a method for installing a canopy upper pull rod full-glass curtain wall node, comprising the following steps:

[0011] Step 1: Weld the vertical and horizontal keels of the canopy on the ground to form a complete canopy frame;

[0012] Step 2: hinge and install the hinged section of the stress diagonal rod at the position of the transverse keel corresponding to the nearest steel column;

[0013] Step 3: After the overall installation of the large-span curtain wall steel columns and steel beams is completed, the hinged section of the stress diagonal rod is hingedly installed at the position of the steel column corresponding to the transverse keel;

[0014] Step 4: Use lifting equipment to lift the canopy frame to the designed elevation, and weld the vertical keel to the steel column;

[0015] Step 5: Assemble the adjustment section of the stress inclined tie rod, screw the two screws into the two nuts respectively, and screw the anti-slip rings into the parts of the two screws extending into the interior of the adjustment ring respectively;

[0016] Step 6: Assemble the stress inclined tie rod, rotate the two nuts and the two hinged sections respectively, align the four-hole flanges on the two screws with the four-hole flanges of the two hinged sections respectively, and connect them respectively with bolts;

[0017] Step 7: After completing the assembly of the stress inclined tie rod, start to rotate the adjustment rod to tighten the entire stress inclined tie rod to a straight line, and continue to rotate the adjustment rod to meet the design tension requirements;

[0021] The canopy upper tie rod full glass curtain wall node and the installation method thereof of the present invention have the following significant beneficial effects:

[0022] (1) The awning keel is directly welded to the steel column of the large-span curtain wall. Since the awning glass is large and spans three cantilevered vertical keels, the deflection deformation is large, and the awning steel frame needs to be pre-arched. The alternating upper arch keel and lower arch keel of the present invention can further offset the internal stress and make the force on the entire awning keel more uniform, thereby improving the stability of the awning keel;

[0023] (2) The contact position between the curtain wall glass and the canopy steel beam was pre-processed. The reaction force of the arch is a downward pulling force, so the steel beam needs to be arched. In order to reduce the impact on the glass curtain wall body, the bottom of the glass curtain wall is set in a wave arc shape to match its force. By setting a silicone structural sealant buffer, the steel beam can transmit force more smoothly, avoiding concentrated force on the glass curtain wall.

[0024] (3) By setting up a stress diagonal brace, the splicing efficiency of the diagonal brace can be improved. Since the diagonal brace is a rigid structure, bending will destroy its performance. The installation of the diagonal brace is often affected by the length of the reserved space. If the length of the reserved space is too long, the connection on both sides cannot be guaranteed. If the length of the reserved space is too short, the diagonal brace cannot be placed in the installation position. Therefore, in the face of the installation difficulties caused by the length, an adjustment section is set, and the nut of the adjustment section is hinged to the connecting rod, which further facilitates the assembly and connection installation of the stress diagonal brace.

[0038] A steel beam 101 is also provided at the connection node between the vertical keel 201 and the steel column 100. Both ends of the steel beam 101 are respectively connected to the connection nodes between the adjacent vertical keel 201 and the steel column 100. Curtain wall glass 400 is fixedly installed on the adjacent steel column 100. The top of the curtain wall glass 400 is connected to the steel beam 101 through a silicone structural sealant 401.
