Description

Technical Field

[0001] The invention relates to the field of sliding doors, and in particular to a connection node of an upper track beam of an electric sliding door. Background Art

[0002] Electric sliding doors are divided into top-loaded electric sliding doors and bottom-loaded electric sliding doors. For sliding doors with larger door leaves and a larger weight per leaf, bottom-load bearing is usually adopted. Under the action of horizontal wind load and horizontal earthquake, the horizontal force on the door is respectively transmitted to the upper and lower guide rails arranged on the structure. The lower guide rail is buried in the foundation to transmit the weight and horizontal action of the door body, and the upper guide rail is installed on the relevant structure to transmit the horizontal action of the door body.

[0003] The door body is relatively large, with a single door of 32m×22.5m and a door opening of 32m×90m. There are 4 sliding doors in total, with a one-time opening width of 45m. If it is located at the seaside, it is often affected by typhoons and the stability of the door body cannot be guaranteed, which poses a huge safety hazard. Therefore, it is necessary to transfer the force borne by the upper guide rail to a stable connection node on the truss. Summary of the invention

[0004] In order to achieve the above-mentioned purpose, a connection node of the upper end track beam of an electric sliding door includes a hanging rail assembly, a reinforcing steel and a connecting plate, wherein the hanging rail assembly is connected to and fixed to the rods of the door top roller and the truss, the reinforcing steel is arranged on the hanging rail assembly, and one end of the reinforcing steel is fixedly connected to the "H"-shaped steel of the truss, and the connecting plate is integrally arranged on the reinforcing steel and the rods of the truss, and connects and fixes the reinforcing steel and the rods of the truss.

[0005] Furthermore, the hanging rail assembly includes a track beam and a hanging rod, the track beam is an "H"-shaped steel, the top roller of the electric sliding door is in contact with the flange plate of the "H"-shaped steel, and is slidably connected to the flange plate, one end of the hanging rod is fixedly connected to the flat web in the groove of the track beam, and the other end is connected to the rod of the truss, and the hanging rail assembly is connected to the top roller of the door and the rod of the truss respectively through the track beam and the hanging rod.

[0006] Furthermore, the number of the hanging rail assemblies is no less than 2, the structures of the no less than 2 hanging rail assemblies are the same, and they are arranged in parallel with equal intervals.

[0017] The following will provide a more detailed description of the connection node of the upper track beam of an electric sliding door of the present invention in conjunction with a schematic diagram, wherein a preferred embodiment of the present invention is shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the present invention.

[0018] like Figure 1As shown, a connection node of the track beam at the upper end of an electric sliding door includes a hanging rail assembly 2, a reinforced steel 3 and a connecting plate 4. The hanging rail assembly 2 connects and fixes the door top roller and the rod 1 of the truss. The number of hanging rail assemblies 2 is not less than 2, and a plurality of hanging rail assemblies 2 are arranged in parallel at equal intervals. The hanging rail assembly 2 includes a track beam 22 and a hanging rod 21. The track beam 22 is arranged on the side of the door top roller of the electric sliding door. The door top roller is fixed by the track beams 22 arranged on both sides thereof. The load force of the electric sliding door is also transmitted to the hanging rail assembly 2 via the door top roller above it and the track beam 22 fixedly connected to the door top roller, and then transmitted to the rod 1 of the truss via the hanging rail assembly 2, and then transmitted to the truss.

[0019] The track beam 22 is an "H"-shaped steel; the door top roller is arranged between the two track beams 22 and is slidably connected to the flange plate of the "H"-shaped steel. Figure 2 As shown, one end of the hanger 21 of the hanging rail assembly 2 is fixedly connected to the flat web of the "H"-shaped steel, and a hanger connecting plate 23 is provided on the end surface of the other end. The hanger connecting plate 23 is vertically arranged with the hanger 21, and the hanger connecting plate 23 has a connecting surface extending relative to the end surface of the hanger 21; the connecting surface is fixedly connected to the rod 1 of the truss.

[0020] Since the suspension rod connecting plate 23 and the truss rod 1 are connected by the connection area, in order to prevent the connection from being loose, we set the above-mentioned reinforcing steel 3 at the angle between the suspension rod connecting plate 23 and the suspension rod 21. Figure 3 , the reinforcing steel and the hanger are arranged perpendicular to each other, and the reinforcing steel 3 and the hanger 21 have the same structure, which is a channel steel. The reinforcing steel 3 and the hanger 21 are fixed by a back-to-back connection between the back sides of the groove surface of the channel steel, and the connecting surface extending from the hanger connecting plate 23 is connected and fixed to the side of the channel steel groove. And one end of the reinforcing steel 3 is also connected to the "H" steel of the truss. Because there are no less than 2 hanging rail assemblies 2, the hangers 21 between the hanging rail assemblies 2 are connected and fixed in the same way through this reinforcing steel 3.

[0021] A connecting plate 4 placed on the reinforcing steel 3 and the truss rod 1 is integrally attached between the reinforcing steel 3 between each two hanging rail assemblies 2, and the connecting plate 4 is used to fix the reinforcing steel 3 and the truss rod 1 and to strengthen the connection and fixation between the hanging rod 21 and the truss rod 1 to solve the above problem. The reinforcing steel 3 fixed on the hanging rod 21 increases the contact area with the truss rod 1, prevents the deformation or fracture caused by the small contact area between the hanging rod 21 and the truss rod 1, and basically eliminates the safety hazards in this regard.

[0022] refer to Figure 2 and Figure 4Similarly, the contact area of ​​one end of the hanger 21 fixedly connected to the track beam 22 is also only the area of ​​the end face of the hanger 21. In order to prevent breakage or deformation caused by too small a contact area, which would cause a huge safety hazard, we set a reinforcing plate 24 at the bottom of this section of the hanger 21. The cross-section of the reinforcing plate 24 is in the shape of an upper trapezoid and a lower rectangle. The length of the upper base d1 of the upper trapezoid is equal to the length of the hanger 21 in the same direction, and the length of the lower base d2 is the same as the groove width of the "H"-shaped steel of the track beam 22. The width h of the rectangle is the same as the groove depth of the "H"-shaped steel of the track beam 22. This structural setting enables the reinforcing plate 24 to be fixed by clamping the internal groove of the track beam 22 and sticking to the upper concave surface of the hanger 21, and fixedly connected to the hanger 21 and the track beam 22, thereby increasing the contact area between the hanger 21 and the track beam 22, making the connection between the track beam 22 and the hanger 21 more stable, and preventing safety hazards.

[0023] It is worth mentioning that all the connection methods of the present invention are welding. In order to prevent the arc surface between the rolled H-steel flange and the web when welding the reinforcing plate 24, a 45° angle is inverted at the connection between the reinforcing plate 24 and the bottom corner of the groove of the track beam "H" steel. The weld is divided into two sections, which also prevents the weld deformation caused by the reinforcing plate 24 and the groove of the track beam 22 being too long and the welding points being too dense.

[0024] Similarly, due to the obstruction of the hanger connecting plate 23 between the reinforcing steel 3 and the truss rod 1, the reinforcing steel 3 and the truss rod 1 are not directly connected, but are connected and fixed through the hanger connecting plate 23 and the connecting plate 4. Accordingly, the welding area is not that large, which can achieve a stable connection effect and prevent the deformation of the truss rod 1 and the reinforcing steel 3 due to welding due to excessive length between the reinforcing steel 3 and the truss rod 1.

[0025] Through the above-mentioned connection structure, the present invention can not only transmit the horizontal force of the door to the truss during strong winds or even typhoons, but also ensure that no deformation or even breakage occurs when the horizontal force is transmitted, thereby ensuring the safety of the door.

[0026] The above is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which does not depart from the content of the technical solution of the present invention and still falls within the protection scope of the present invention.
