Description

Technical Field

[0001] The invention relates to the technical field of canopy construction, in particular to a multi-tie rod intersection node structure for a large cantilevered canopy. Background Art

[0002] At present, large cantilever steel structure canopies are widely used in large-span public buildings and industrial plants. Compared with reinforced concrete structure canopies, they have the advantages of high strength, light weight, flexible structure, no impact on travel and no obstruction of sight. The main body of the large cantilever steel structure canopy is composed of cantilever steel beams and steel tie rods. After prefabrication in the factory, it is transported to the site to connect the steel tie rods with the embedded parts on the steel columns or concrete columns of the building. When the column distance of the building is large and the canopy cantilever is too long, in order to ensure the overall structural strength of the canopy, multiple tie rods will be set at the same point of a frame column to tie multiple cantilever steel beams between the columns. Since the tie rods converge at one place on the frame column, the embedded parts connecting the tie rods are also gathered in a limited range. In order to ensure the installation accuracy, it is necessary to deepen the design work. When there is a difference between the embedded position of the embedded parts and the design scheme, it will increase the difficulty of on-site installation and extend the installation period.

[0013] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific construction process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0014] like Figure 1-3As shown, the multi-tie rod intersection node structure for a large cantilever canopy of the present invention is connected to the tie rod 2 through an embedded part set in the frame column 1. The frame column 1 is a square column of reinforced concrete structure. The embedded part includes an embedded plate 31 attached to the outer wall of the frame column 1. The back of the embedded plate 31 is provided with an anchor bar 32 extending into the frame column 1. The front of the embedded plate 31 is welded with an upper bearing plate 33 and a lower bearing plate 34 extending in the direction of the canopy. The upper bearing plate 33 and the lower bearing plate 34 are equal in size, correspond to each other up and down, and are both arranged in the horizontal direction. A cylindrical bearing body 35 is arranged between the upper bearing plate 33 and the lower bearing plate 34, and a vertical reinforcing plate 36 is arranged between the cylindrical bearing body 35 and the embedded plate 31. In general, the vertical reinforcing plate 36 is arranged on the central axis of the upper bearing plate 33 and the lower bearing plate 34, and its top is welded to the upper bearing plate 33, and its bottom is welded to the lower bearing plate 34, and its two ends are respectively welded to the embedded plate 31 and the cylindrical bearing body 35. The upper bearing plate 33, the lower bearing plate 34 and the vertical reinforcing plate 36 are all made of steel plates with a thickness of 16 mm, and the cylindrical bearing body 35 is made of a round steel pipe with a diameter of φ300×20. The setting of the cylindrical bearing body 35 increases the installation working surface of the tie rod 2. In this embodiment, according to the installation number and installation position of the tie rod 2, three pairs of ear plates 37 are welded on the outer circumference of the cylindrical bearing body 35, and a rotating plate 39 connected by a hinge shaft 38 is arranged between each pair of ear plates 37, and a mounting plate 310 for connecting the tie rod 2 is welded at the end of the rotating plate 39. One pair of ear plates 37 is symmetrically arranged along the central axis of the vertical reinforcing plate 36, and the other two pairs of ear plates 37 are symmetrically arranged on both sides thereof, and the angle between the two adjacent pairs of ear plates 37 is 54.5°, and the hinge shafts 38 installed in the above ear plates 37 are all located in the same horizontal plane, that is, the rotation center of the rotating plate 39 is located in the same horizontal plane. Since the rotating plates 39 can rotate freely around their respective hinge shafts 38 in a vertical plane, and the ends of the rotating plates 39 are connected to the mounting plates 310 perpendicular thereto, when installing the pull rod 2, the specific position of the rotating plates 39 can be adjusted to facilitate the welding of the pull rod 2 and the mounting plates 310. The above-mentioned ear plates 37, rotating plates 39 and mounting plates 310 are all made of steel plates with a thickness of 12 mm, and the outer diameter of the hinge shaft 38 is 40 mm. In order to strengthen the connection between the ear plates 37 and the cylindrical carrier 35, a reinforcing rib plate 311 is also provided on the outer side of each ear plate 37 and is welded to the cylindrical carrier 35.

[0015] When the present invention is in use, the embedded parts are first designed and processed according to the cantilever canopy and the building design drawings. Then, when the frame column 1 is constructed, the embedded parts are installed on the frame column 1. After the building construction is completed, the canopy body is transported to the site and hoisted to an appropriate height so that the tie rod 2 corresponds to the embedded parts. The specific angle of the rotating plate 39 is adjusted so that the tie rod 2 is connected to the mounting plate 310, and then welding is performed to complete the connection between the tie rod 2 and the embedded parts.

[0016] The embedded parts described in the present invention are provided with hinged installation nodes set according to the number and installation positions of the tie rods, which reduce the complexity of the tie rod intersection nodes to a certain extent, greatly facilitate the on-site installation of the tie rods, are not only beautiful and elegant, but also can improve the installation accuracy of the tie rods, shorten the on-site installation time, thereby saving project costs, and have good market prospects.

[0017] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
