Problems solved by technology

[0003] Traditional fire windows need to ensure thermal insulation (low K value) and fire-resistant integrity at the same time, which is often difficult to achieve. Only by making the frame system into a broken bridge form and the glass into fire-resistant glass can basically meet the requirements, and the cost is very high. , but the frame system in the form of a broken bridge has a complex section shape, which is only suitable for the aluminum frame system, and cannot be realized in the steel frame system with better fire performance

Embodiment 1

[0026] Figure 1 to Figure 2 It shows the first embodiment of the rotary snap-fit ​​cold curtain fireproof door and window system of the present invention, including fixed steel frame 1, fireproof board 2 and cold curtain board 3 with heat insulation function, fireproof board 2 and cold curtain board 3 to form a connection, the fixed steel frame 1 has a frame opening 11 to ensure permeability, the inner wall of the corresponding frame of the fixed steel frame 1 is pre-installed with a rotating clip 4 through bolts, and the fireproof board 2 is set on the frame opening 11 Inside, the rotating clamping member 4 rotates the angle and is locked with the edge of the fireproof board 2 after the bolt is locked. The cold curtain plate 3 covers the fixed steel frame 1 and the frame opening 11 and is located outside the frame opening 11. During installation, the rotating clip 4 is pre-installed on the inner wall of the corresponding frame through bolts, and then the fireproof board 2 is...

Embodiment 2

[0036] image 3 It shows the second embodiment of the cold curtain fireproof door and window system of the present invention with rotary clamping type. The door and window system is basically the same as that of Embodiment 1, the only difference is that in this embodiment, the bead 6 is buckled with the fixed steel frame 1 . The utility model has the advantages of simple structure and convenient installation.

Abstract

The invention discloses a rotary clamping type cold curtain fireproof door and window system. The rotary clamping type cold curtain fireproof door and window system comprises a fixed steel frame, a fireproof plate and a cold curtain plate with a heat insulation function, wherein the fireproof plate is connected with the cold curtain plate; a frame opening for guaranteeing the permeability is formed in the fixed steel frame; a rotary clamping piece is pre-mounted on the inner side wall of a corresponding edge frame of the fixed steel frame through a bolt; the fireproof plate is arranged in the frame opening; the rotary clamping piece is rotated by an angle and is locked by the bolt to be clamped with the edge of the fireproof plate; and the cold curtain plate covers the fixed steel frame and the frame opening and is located outside the frame opening. The door and window system has the advantages of simple and reliable structure, low cost, heat insulation performance and fireproof performance.

Description

technical field [0001] The invention mainly relates to the field of construction engineering, and in particular to a rotating clamping type cold curtain fireproof door and window system. Background technique [0002] As the country has higher and higher requirements on the performance of fire-resistant windows, it is required to ensure excellent air-tightness, water-tightness and thermal insulation performance while meeting the fire-resistant integrity. [0003] Traditional fire windows need to ensure thermal insulation (low K value) and fire-resistant integrity at the same time, which is often difficult to achieve. Only by making the frame system into a broken bridge form and the glass into fire-resistant glass can basically meet the requirements, and the cost is very high. , but the frame system in the form of a broken bridge has a complex section shape, which is only suitable for the aluminum frame system, and cannot be realized in the steel frame system with better fire ...
