Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof rolling doors, and particularly relates to a heat-insulating guide rail for a fireproof rolling curtain. Background Art

[0002] Fireproof rolling curtains are mainly used for walls that need fire separation, especially for fire separation when large openings need to be opened on firewalls and fire partitions due to production, use, etc., and fire doors cannot be installed.

[0003] A fireproof rolling door is composed of a rolling curtain, a reel, a motor, a guide rail, a bracket, a protective cover, a control mechanism, etc. Among them, two guide rails are fixed on both sides of the door opening, and both sides of the rolling curtain (i.e., the curtain board) can slide in the track grooves of the guide rails. In case of a fire, after the fireproof rolling door is lowered, although a sealing strip is provided in the guide rail to enhance the sealing between the rolling curtain and the guide rail, the steel guide rail does not have strong fire resistance, and deformation and damage of the guide rail may still occur after being roasted by high temperature fire for a long time, affecting the overall fireproof effect of the rolling door. Therefore, the purpose of the present utility model is to provide a guide rail with good heat-insulating performance for a fireproof rolling door. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the present utility model provides a heat-insulating guide rail for a fireproof rolling curtain.

[0005] The technical solution of the present utility model is as follows: A heat-insulating guide rail for a fireproof rolling curtain, the guide rail is arranged in a groove shape, its bottom surface is an installation surface, its two sides are side walls, and two clamping surfaces are arranged at the top. A clamping groove is arranged at the edge of each clamping surface, and the two clamping grooves form a sliding groove, and the fireproof rolling curtain can lift and slide in the sliding groove; fireproof layers are arranged on the inner sides of the two side walls of the guide rail;

[0006] The fireproof layer is a layer made of an inorganic fiber composite material.

[0007] Further, the fireproof layer is a soft board layer, and it can be made of a layer of aluminum silicate cotton or a layer of asbestos or a layer of glass fiber or a layer of ceramic fiber.

[0008] Further, the fireproof layer can be adhered to the side wall, or can be bent and clamped in a groove formed inside the guide rail.

[0009] Further, the fireproof layer is a hard board layer, and it can be made of a rock wool fireproof board or a mineral wool fireproof board or a glass wool board or a water leakage fireproof board.

[0010] Further, the fireproof layer can be clamped between the installation surface and the clamping surface and is arranged closely against the inner wall of the side wall.

[0011] Advantages of the present utility model:

[0012] 1. In the design scheme of the present utility model, in addition to the sealing rubber strip provided in the guide rail, fireproof layers are also provided on the side walls on both sides thereof. The fireproof layers can play a good heat insulation effect inside the guide rail, enhance the overall fire resistance performance of the guide rail, and increase the fire resistance duration.

[0013] 2. In the design scheme of the present utility model, when installing the fireproof layer in the guide rail, it can be directly adhered to the side wall of the guide rail in advance, or it can be cut into appropriate sizes and then directly snapped into the guide rail. The installation methods are diverse and the installation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] As Figure 1 -3 shows, a heat-insulating guide rail for a fire shutter, the guide rail 1 is arranged in a groove shape, its bottom surface is the installation surface 101, its two sides are side walls 102, and two clamping surfaces 103 are arranged at its top. A clamping groove 104 is arranged at the edge of each clamping surface 103, and the two clamping grooves 104 form a sliding groove, and the fire shutter can be lifted and slid in the sliding groove; a fireproof layer 106 is arranged on the inner sides of the two side walls 102 of the guide rail 1; the fireproof layer 106 is a layer made of an inorganic fiber composite material.

[0023] Specifically, the fireproof layer 106 can adopt a soft plate layer, which can adopt a layer made of aluminosilicate cotton or asbestos or glass fiber or ceramic fiber. Such a fireproof layer 106 can be adhered to the side wall 102, or can be bent and clamped in the groove formed inside the guide rail 1.

[0024] Specifically, the fireproof layer 106 can adopt a hard plate layer, which can adopt a rock wool fireproof board, a mineral wool fireproof board, a glass wool board, a water leakage fireproof board. Such a fireproof layer 106 can be clamped between the installation surface 101 and the clamping surface 103 and is arranged closely against the inner wall of the side wall 102.

[0025] During installation, regarding the installation of the fireproof layer 106, as Figure 3-1 、 3-3 shows, the soft fireproof layer 106 can be fixed on the inner wall of the side wall 102 by adhesion, or can be directly bent and clamped in the groove inside the guide rail 1 after being cut into a suitable size; as Figure 3-2 shows, the hard fireproof layer 106 (fireproof board) can be directly clamped between the clamping surface 103 and the installation surface 101 and is arranged closely against the side wall 102. Whether it is a soft or hard fireproof layer 106, its installation method is relatively convenient.

[0026] During use, the fireproof layer 106 cooperates with the sealing strip 105 in the sliding groove of the guide rail 1, so that the inside of the guide rail 1 can achieve a good heat-insulating effect, enhance the overall fire resistance of the guide rail 1, and increase the fire resistance duration.

[0027] So far, the embodiments of the present utility model have been described in detail. To avoid obscuring the concept of the present utility model, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
