Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to a connecting device. Background Technology

[0002] In building construction, the installation quality between floor decking and steel beams directly affects the stability and safety of the building structure. Currently used welding and bolting connections have some significant shortcomings in practical applications.

[0003] High-temperature welding operations can alter the microstructure of steel, damaging the material of steel beams and floor decks and affecting their mechanical properties. Residual welding stress can easily cause deformation of components, increasing the workload and construction costs of subsequent corrections. Welding also requires a high level of skill from operators and a suitable working environment.

[0004] While bolted connections are relatively simple to install, they are prone to loosening under the influence of alternating stresses from personnel activity, equipment vibration, and wind loads during long-term use. Bolted connections require high installation precision, but limited space on site makes alignment at the connection point difficult, leading to deviations that prevent the floor decking from being installed smoothly or result in a loose connection. Under long-term alternating loads, bolts may experience fatigue failure, and coupled with the effects of environmental corrosion, their durability and load-bearing capacity will gradually decrease. Utility Model Content

[0016] And / or, the extension length of the connector is the same as the extension length of the first connector to be connected.

The connecting device includes: a connecting member 3 disposed on the first component 1, the extension length direction of the connecting member 3 being the same as the extension length direction of the first component 1, and the connecting member 3 and the second component 2 being spaced apart; a first fixing member 4 fixed to the connecting member 3; a second fixing member 5 fixed to the second component 2; and a fastener 6 fixedly connected between the first fixing member 4 and the second fixing member 5.

[0044] By first placing the second component 2 on the first component 1 and then fixing it, the connection stability and reliability between the first component 1 and the second component 2 can be improved, thus enabling long-term use. By setting the connector 3, the height of the first fixing component 4 can be increased, so that the first fixing component 4 and the second fixing component 5 are at the same height, which is convenient for installation. By using fasteners 6 to fix the first fixing component 4 and the second fixing component 5, the connection is convenient and can reduce on-site operations, thereby improving construction efficiency, reducing costs, avoiding damage to the first component 1 or the second component 2, and thus being able to adapt to the connection of different types of first component 1 and second component 2.

[0045] like Figures 2-3 As shown, in one embodiment, the first component to be connected, 1, is a steel beam; the second component to be connected, 2, is a floor deck.

As an alternative implementation, the first fixing plate 41 may be omitted, and the first sleeve 42 may be directly fixed to the connecting member 3; no further restrictions are imposed here.

[0053] like Figure 4 As shown, in one embodiment, the second fixing member 5 includes: a second fixing plate 51, fixed to the floor deck; and a second sleeve 52, fixed to the side of the second fixing plate 51 away from the floor deck, the second sleeve 52 having a second through hole. As an alternative implementation, the second fixing plate 51 may be omitted, and the second sleeve 52 may be directly fixed to the floor deck; no further restrictions are imposed here.

[0054] like Figures 4-5As shown, in one embodiment, the first through hole and the second through hole are threadedly connected to the fastener 6. Specifically, the first through hole has a first internal thread, the second through hole has a second internal thread, and the fastener 6 has an external thread that mates with the first and second internal threads. The fastener 6 is a threaded steel bar. By threading the fastener 6 to the first fixing member 4 and the second fixing member 5, the connection method is simple, the connection is secure, and installation is convenient. As an alternative implementation, the fastener 6 can also be a screw.
