Description

Technical Field

[0001] The utility model relates to the technical field of suspended ceiling construction, in particular to a spherical grid suspended ceiling conversion connection structure with a large span and a large conversion height. Background Art

[0002] Airport terminals, station waiting rooms, factories, warehouses and other large-space, large-span building structures mostly use spherical grid rock wool sandwich insulation corrugated steel plate roofs. The roofs of such large-space steel structures are generally installed with suspended ceilings to shield air ducts and other installed equipment to enhance the indoor appearance, while reducing the indoor effective floor height, which is beneficial to energy saving.

[0003] However, due to the large height between the steel structure roof and the ceiling decoration layer, the decorative ceiling cannot be directly connected to the grid ball node through the hanger. When the hanger length is greater than 1.5m, a transition layer needs to be set up for reverse support, otherwise the hanger will "become soft and bent". At the same time, since the span between adjacent spherical grid ball nodes is also large, the horizontal transfer beam of the transition layer is prone to tension and deflection. The weight requirements for the ceiling decoration layer are relatively strict, the applicability is poor, and it will also affect the molding effect of the finished surface of the decorative ceiling, resulting in a decline in appearance and difficulty in meeting construction requirements.

In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the utility model and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-3 , the preferred embodiments of the utility model are further described in detail:

[0022] like Figure 1-3As shown, the utility model preferably adopts a large-span, large-conversion-height spherical grid ceiling conversion connection structure, comprising a conversion steel plate 3, a vertical strut 4, an oblique tie rod 5 and a conversion beam 6. The conversion steel plate 3 is made of galvanized steel plate, and the conversion steel plate 3 is fixed to the bottom end of the spherical grid ball node 1 by a high-strength bolt 2. The conversion beam 6 is correspondingly arranged below the conversion steel plate 3, and the conversion beam 6 is arranged parallel to the main keel 8 of the ceiling. The vertical strut 4 is arranged in the vertical direction, and its top and bottom ends are respectively fixed on the conversion steel plate 3 and the conversion beam 6. The oblique tie rod 5 is arranged in pairs, and the two oblique tie rods 5 arranged in pairs are correspondingly arranged on both sides of the vertical strut 4, and their top and bottom ends are respectively fixed on the conversion steel plate 3 and the conversion beam 6, and their rod bodies are arranged in an inclined state. The arrangement of the oblique tie rod 5 can effectively reduce the span of the conversion beam 6 and avoid the problem of downward deflection due to the weight of the ceiling.

[0023] In order to ensure the stability of the ceiling structure, the vertical support rods 4, the diagonal tie rods 5 and the transfer beams 6 are all required to be made of materials with greater rigidity and lighter weight. For this reason, the vertical support rods 4, the diagonal tie rods 5 and the transfer beams 6 are preferably made of galvanized angle steels. Compared with other cross-section steels, galvanized angle steels have the characteristics of being lightweight, lighter in weight, and having good bending resistance. They can achieve the purpose of reducing the difficulty of construction and saving the amount of steel while ensuring the stability of the transfer layer structure.

[0024] From the perspective of convenient installation, the main keel 8 of the suspended ceiling is suspended below the conversion beam 6 through the suspension rod 7. The top of the suspension rod 7 is welded and fixed on the conversion beam 6, and the bottom end thereof penetrates the main keel 8 of the suspended ceiling and is fixedly connected to the main keel 8 of the suspended ceiling through the nut 9 provided in a matching manner. In this arrangement, it is only necessary to make a hole in the main keel 8 of the suspended ceiling, and no hole is required to be made in the conversion beam 6, so as to avoid the problem that the upper and lower holes cannot be aligned due to on-site installation errors, resulting in the inability to install the suspension rod 7, which can effectively reduce the difficulty of installation and improve the flexibility of the construction site;

[0025] Since the horizontal span between two adjacent spherical grid ball nodes 1 of the large space steel structure is large, the stability of the segmented conversion beam 6 is difficult to meet the requirements of the ceiling setting. For this reason, it is advisable to set the conversion beam 6 as a full-length structure within the distribution range of the ceiling. On this basis, for the purpose of convenient installation, a single conversion beam 6 set up in the full length can be assembled from several sections of standard sections and connecting sections. The connecting section can adopt the structure of steel plate strips or angle steels. The standard sections and connecting sections can be fixed by welding or bolting. At this time, a section of standard section of conversion beam 6 is correspondingly arranged under each spherical grid ball node 1, and the bottom end of the oblique pull rod 5 is fixedly arranged at the section between the sixth and eighth points of the standard section of the conversion beam 6 close to the end to ensure the stability of the conversion beam 6.

[0026] The installation process of the utility model is as follows (taking a specific construction project as an example),

[0027] 1. A 20mm bolt hole is reserved at the bottom of the original spherical grid ball node 1. A high-strength bolt 2 with a diameter of 20mm and a length of 100mm is used. The upper part of the high-strength bolt 2 is bolted to the original spherical grid ball node 1 (the high-strength bolt 1 extends into the inside of the spherical grid ball node 1 by no less than 50mm). The lower part of the high-strength bolt 2 is welded to a conversion steel plate 3 made of a square hot-dip galvanized steel plate (200×200×10mm) to form a whole;

[0028] 2. A vertical support rod 4 made of angle steel (50×50×5mm) is welded below the conversion steel plate 3, a conversion beam 6 made of angle steel (50×50×5mm) is welded to the bottom of the vertical support rod 4, and oblique tie rods 5 made of angle steel (50×50×5mm) are used to reinforce the two sides of the vertical support rod 4. The top of the oblique tie rod 5 is welded and fixed to the conversion steel plate 3 and the vertical support rod 4, and the bottom of the oblique tie rod 5 is welded to the conversion beam 6 to complete the structural conversion layer system;

[0029] 3. Install the main ceiling keel 8 through the suspension rod 7 with a diameter of 8 mm under the transfer beam 6, and complete the installation of the secondary ceiling keel (not shown in the figure) under the main ceiling keel 8 through the hanging assembly.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
