Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and in particular to a device for connecting fireproof boards to I-beams. Background Technology

[0002] As a primary load-bearing component in building structures, the fire resistance of I-beams directly affects the overall safety of the building. Under fire conditions, the strength of steel beams decreases sharply with increasing temperature, therefore reliable fire protection measures must be taken. Installing fire-resistant boards (such as gypsum board, calcium silicate board, or fiber-reinforced cement board) on the flanges and webs of I-beams is a widely used and effective passive fire protection method.

[0003] Currently, traditional fireproof board installation methods mainly rely on welding connectors or direct fixing with self-tapping screws. Specifically, construction workers first need to weld a large number of metal connectors such as angle steel, threaded rods, or bolts at predetermined locations on the I-beam to form a supporting frame. The fireproof board is then fixed to this frame using self-tapping screws, or indirectly installed using a keel system. However, these existing technologies have inherent drawbacks, including damage to the base material due to welding, low construction efficiency, high safety risks, and insufficient connection reliability.

[0004] Therefore, there is an urgent need in this field for a special device that requires no welding, does not damage the I-beam base material, is quick to install, and provides a reliable connection, in order to overcome the aforementioned limitations of the prior art and achieve an efficient, safe, and reliable connection between the fireproof board and the I-beam. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a device for connecting fireproof boards to I-beams. This invention enables the connection between fireproof boards and I-beams, improving the reliability of the connection.

[0007] The first cap-shaped nut, the first through-thread stud, the U-shaped groove with a hole, the threaded hole, the clamping screw and the handle together constitute a set of end clamping devices;

[0008] As an optimization, the first through-thread stud is connected to the U-shaped groove with a hole; the inner wall of the first cap nut is provided with an internal thread that matches the external thread of the first through-thread stud; by screwing the first cap nut, it can be driven to move along the axial direction of the first through-thread stud.

[0009] As an optimization, a threaded hole is provided on the U-shaped slot with holes; the clamping screw is threaded in the threaded hole, so that when the clamping screw is turned, it can be driven to move axially.

[0010] As an optimization, a handle is provided at one end of the clamping screw.

[0011] The second cap-shaped nut, the second through-thread stud, the U-shaped groove, and the elastic clip together constitute an intermediate clamping device;

[0012] As an optimization, the U-shaped slot is fixedly connected to a second through thread stud; the second cap-shaped nut is sleeved on the outside of the second through thread stud, and the two form a threaded transmission pair through matching internal and external threads; by screwing the second cap-shaped nut, it can be driven to move along the axial direction of the second through thread stud.

[0013] As an optimization, two elastic clips are fixed to the inner sides of the two side walls of the U-shaped slot.

[0015] 1. This utility model achieves a weld-free connection with the I-beam through a clamping mechanism consisting of a U-shaped slot with holes, a first through-thread stud, and a first cap-shaped nut.
