Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and particularly relates to an adjustable connecting device for an assembled truss transfer story. Background Art

[0002] The long-span steel structure grid structure is a common large-scale roof structure. When a decorative layer is arranged below the long-span steel structure grid structure, a suspender connecting piece is required. One end of the suspender connecting piece is connected to the steel pipe of the long-span steel structure grid structure through a hoop, and the other end is connected to the keel of the decorative layer through a clamp.

[0003] When installing the decorative layer, the clamp of the suspender connecting piece needs to be temporarily installed on the keel first, and then, while the keel is lifted to the designed position, the clamp needs to be connected to the suspender to complete the installation of the keel of the decorative layer. In this installation method, since a plurality of clamps are often arranged on the keel, a plurality of suspender connecting pieces need to be in place synchronously, resulting in difficult positioning of the keel and difficult adjustment of the position of the keel. In addition, the size of the clamp of the existing suspender connecting piece is fixed and cannot adapt to keels of different specifications, which brings inconvenience to construction. Summary of the Invention

[0004] In order to improve the installation quality of the decorative layer and improve the construction efficiency, the utility model provides an adjustable connecting device for an assembled truss transfer story.

[0005] The technical solution of an adjustable connecting device for an assembled truss transfer story of the utility model is as follows:

[0006] An adjustable connecting device for an assembled truss transfer story comprises a hoop, a connecting piece, a suspender, a clamp and a first fixing nut; one end of the connecting piece is connected to the hoop, and the other end is connected to the upper end of the suspender; the clamp comprises a first clamp and a second clamp; a folding plate is arranged at one end of the first clamp; a clamping groove matched with the folding plate is arranged at one end of the second clamp; the folding plate is inserted into the clamping groove; the suspender penetrates through the other ends of the first clamp and the second clamp; the first fixing nut is screwed on the lower side of the clamp.

[0007] When the adjustable connecting device for an assembled truss transfer story of the utility model is used, first, the hoop is connected to the steel pipe of the long-span steel structure grid structure. Then, the clamp is installed on the suspender, and the first clamp and the second clamp are respectively temporarily fixed at the upper end or the lower end of the suspender, leaving a space for installing the keel of the decorative layer; then, the first clamp and the second clamp are closed, the keel is placed in the clamp, and the folding plate is inserted into the clamping groove; finally, the clamp is fixed to complete the connection between the keel and the steel pipe.

[0008] An adjustable connection device for a truss transfer floor assembly of the present utility model. When the keel is moved to the designed position, it is not necessary to install the clamp simultaneously, making the installation of the keel more flexible, thus simplifying the installation process of the keel. Moreover, before the folding plate is inserted into the card slot, the position of the keel can be finely adjusted. In addition, the folding plate and the card slot cooperate to enable the clamp to adapt to keels of different heights, thereby increasing the adaptability of the adjustable connection device for the truss transfer floor assembly.

[0009] Further, in the adjustable connection device for the truss transfer floor assembly, the connecting member includes triangular frames oppositely arranged on both sides of the ear plates of the hoop, and a rectangular frame arranged on the lower side of the triangular frames; the suspension rod is connected to the middle of the lower side of the rectangular frame. The suspension rod is arranged in the middle of the rectangular frame, which can make the force on the suspension rod more balanced, thereby improving the stability of the keel connection.

[0010] Further, in the adjustable connection device for the truss transfer floor assembly, it further includes a second fixing nut; the second fixing nut is arranged on the upper side of the clamp. When the clamp fixes the keel, the keel is locked by the second fixing nut on the upper side of the clamp.

[0011] Further, in the adjustable connection device for the truss transfer floor assembly, in order to increase the strength of the clamp, it further includes a connecting plate; both ends of the connecting plate are arranged on the upper and lower sides of the opening of the clamp.
