Description

TECHNICAL FIELD

[0001] The utility model discloses a building roof decoration technical field, concretely is a kind of connecting device for existing building and new decorative component. BACKGROUND

[0002] In the decoration of existing building roof, it is often involved with the connection of the original structure. In the case of the original structure being a concrete beam or column, the connection of the new component and the original structure is usually made by anchor bolt embedded plate, and is completed by welding or bolting with the embedded plate. The above construction method is still feasible on relatively new building structures; but for relatively old buildings (before 2010, especially the building structures in the 1980s and 1990s), the situation is relatively complex, and the above conventional method cannot be implemented due to the reduced concrete strength, exposed steel bars after rusting, etc. If the above method is insisted on, the original building structure needs to be detected and reinforced, resulting in an increase in cost.

[0018] Example 1

[0019] As shown in the drawings, a connecting device for existing building and newly added decorative component, the newly added decorative component is newly added roof decoration or curtain wall. Figs. 1-3 The connecting device comprises a lower connector for connecting with the beam or column of the existing building, and an upper connector for connecting with the batten of the newly added decorative component.

[0020] The lower connector comprises a lower open steel frame 1 and a steel sealing plate 2 at the lower part of the steel frame 1, and the steel frame 1 and the steel sealing plate 2 are connected by bolts; the steel frame 1 comprises a top plate 11, two reinforced side plates 12 vertically connected to the lower end of the top plate 11, and a steel hollow hemisphere 13 buckled at the upper center of the top plate 11; four corners of the top plate 11 are provided with through holes for bolts. Fig. 2 As shown in the figure, each reinforced side plate 12 comprises a vertical steel plate 121, a hole plate 122 vertically connected to the outer side of the lower end of the vertical steel plate 121, and a cross stiffening rib 123 arranged on the outer side of the vertical steel plate 121; the top of the vertical steel plate 121 is connected to the lower surface of the top plate 11. In this embodiment, the components of the steel frame 1 are all connected by welding. The four corners of the steel sealing plate 2 are provided with through holes, and the steel frame 1 and the steel sealing plate 2 are connected by bolts passing through the hole plate 122 at the lower end of the reinforced side plate 12 and the through holes of the steel sealing plate 2.

[0021] The upper connector comprises a connecting steel plate 3, long bolts 4 passing through the four corners of the connecting steel plate 3, and upper and lower two-section springs 5 sleeved outside each long bolt 4.

[0022] The upper connector and the lower connector are connected by the long bolts 4 passing through the four corners of the top plate 11, the upper and lower two-section springs 5 outside the long bolts 4 are separated on the upper and lower surfaces of the top plate 11, and nuts are installed at the bottom of the long bolts. The lower surface of the connecting steel plate 3 is in contact with the vertex of the steel hollow hemisphere 13. The upper surface of the steel hollow hemisphere is provided with a fluorocarbon coating.

[0023] The new decorative component of the keel can be connected to the upper connector by welding, purlin support, etc. The two reinforced side plates of the lower connector are clamped on the original structure beam (or column), and then fixed by connecting the sealing plate through bolts. Then the long bolt of the upper connector only passes through the top plate of the lower connector with the upper section spring, and then the lower section spring is sleeved, and then the nut is installed, and the four corners are operated in the same way. After connection, the vertical load of the roof decoration system is mainly transmitted to the original structure beam through the connecting device. At the same time, the roof decoration system is allowed to have a certain deformation, and the influence of the deformation on the original structure beam is eliminated through the connecting device. The reason why it can be eliminated is that there is a semicircular fulcrum in the connecting device, which can be tilted in any direction; at the same time, the springs at the four corners can provide damping and rebound, so as to ensure that the roof decoration system has a certain deformation during the installation process and use process, and the acting force on the original structure is released.

[0024] The above embodiments are only part of the embodiments of the present application, and cannot cover all the embodiments of the present application. Based on the above embodiments and the drawings, those skilled in the art can obtain more embodiments without creative labor, and therefore the embodiments obtained without creative labor should be included in the protection scope of the present application.
