Detailed Description

The invention is further described below with reference to the accompanying drawings:

examples

An expansion type steel structure corner part protection device with high fire resistance is shown in figures 1-3 and comprises a protection bracket 1, a protective guard 2, a sliding chute 3, a sliding block 4, a fixing block 5, an elastic part 6, a clamping plate 7, a flame-retardant plate 8, a fixing clamping frame 9 and a mounting groove 10; the top of the protection bracket 1 is provided with a mounting groove 10, and the bottom is provided with a chute 3; the fixed clamping frame 9 is uniformly and fixedly connected with the inner side wall of the mounting groove 10; the flame-retardant plate 8 is clamped with the fixed clamping frame 9; the fixed block 5 is fixedly connected to the bottom surface of the protective bracket 1; the guard rail 2 is fixedly connected to the bottom of the protection bracket 1; the clamping plate 7 is connected with the sliding chute 3 in a sliding way through the sliding block 4; one end of the elastic piece 6 is fixedly connected with the clamping plate 7, and the other end is fixedly connected with the fixed block 5; the protective bracket 1 is clamped to a steel structural plate 11 by a clamping plate 7.

The expanded steel structure corner piece protection device with high fire resistance further comprises an insect-proof agent 12; the insect-proof agent 12 is coated on the surface of the flame-retardant plate 8.

The sliding groove 3 is provided with two, the corresponding sliding block 4 and the corresponding clamping plate 7 are both provided with two, and the elastic piece 6 is provided with two.

8-10 fixed clamping frames 9 can be arranged, and 4-5 corresponding flame-retardant plates 8 can be arranged.

The flame-retardant board 8 is made of three-layer or multi-layer plywood formed by gluing wood chips or wood chips blocks subjected to flame-retardant treatment in a mode that the fiber directions of the wood chips of adjacent layers are mutually vertical.

When the steel plates are spliced and erected to form a steel structure building, in the insolation environment, the steel plates on the surfaces of the steel structures are easily attacked by heat to absorb the heat, so that the heat is too large and expands with heat and contracts with cold, under the condition that the steel plates are exposed for a long time, the service life of the steel plates is shortened, the steel plates are broken and threaten the safety of the steel structure building, therefore, the protective device can be used, a worker installs the protective device on the steel structure steel plates 11, the clamping plates 7 on the two sides are pulled to open along the sliding grooves 3 through the sliding blocks 4, the steel structure steel plates 11 are clamped between the two clamping plates 7, after the worker releases the hands, the clamping plates 7 are clamped by the elastic pieces 6 to install the protective device, after the protective bracket 1 is installed, when the sun is insolated, the sunlight can shine on the flame-retardant plates 8, therefore, the steel plates cannot be irradiated by the sun, and the, the plurality of flame retardant plates 8 are also divided into a plurality of layers by the fixing clamping frame 9, a certain distance is arranged between each flame retardant plate 8 to provide enough space for heat exchange, so that the flame retardant plates 8 can conveniently dissipate heat, meanwhile, under the condition of fire, the flame retardant plates 8 block flame generated by the fire, steel plates are prevented from directly contacting the flame, the temperature is reduced, because the flame retardant plates 8 belong to wood materials, compared with other fireproof materials, the flame retardant plates have the inherent defects of natural wood, the burning point of the flame retardant plates is lower than that of other materials, but the flame retardant materials contained in the flame retardant plates can release substances which block combustion, such as nonflammable gases, such as substances which quickly decompose wood fibers, and the like, and the generated non-flammable gases can consume ambient oxygen, so that the flame can lose oxygen to achieve the flame retardant effect, further protecting the steel structure building.

The expanded steel structure corner piece protection device with high fire resistance further comprises an insect-proof agent 12; the insect-proof agent 12 is coated on the surface of the flame-retardant plate 8; since the fire retardant sheet 8 is a wooden sheet, it is inhabited by pests such as termites, and the insect damage can be prevented by applying the insect repellent 12.

Although the present disclosure has been described in detail with reference to the exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes can be made thereto without departing from the scope of the present disclosure.
