Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a heat-insulating fireproof U-shaped bracket. Background Art

[0002] A U-shaped glass bracket generally refers to a bracket or clamp used to support and fix a glass plate. It is U-shaped and can firmly clamp the glass and provide support. By installing the U-shaped glass bracket in an appropriate position and clamping the glass plate into it, the glass can be effectively fixed and supported while beautifying the installation effect.

[0003] The Chinese utility model patent, authorization announcement number CN 213478131 U, discloses an aluminum alloy fire-resistant exterior window, which is supported by an aluminum alloy window frame, a window frame reinforcement steel sheet, a hollow fireproof glass and an aluminum alloy window strip. A U-shaped glass support is arranged at intervals of 300 mm in the horizontal and vertical directions on the inner side of the glass installation groove of the aluminum alloy window frame. The U-shaped glass support is evenly distributed around the installed hollow fireproof glass. A fireproof glass gasket is arranged between the U-shaped glass support and the glass. A full-length aluminum alloy window strip is pressed into the preset groove of the aluminum alloy window frame on the inner side of the glass installation room. The utility model provides an aluminum alloy fire-resistant exterior window, which adopts an aluminum alloy window frame and meets the fire protection requirements through additional structural measures.

[0004] The above scheme realizes the requirements of fire-resistant windows, and the appearance of the facade is consistent with that of ordinary aluminum alloy windows, which meets the facade effect. However, there are still certain defects in application. When encountering fire or high temperature, the fire-resistant sealant will lose its bonding properties, and the U-shaped glass support may also expand due to high temperature, causing its size to change, and finally causing it to lose its support and fixing function for the hollow fire-resistant glass. Utility Model Content

[0005] The purpose of the utility model is to provide a heat-insulating fireproof U-shaped bracket to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat-insulating fireproof U-shaped bracket, comprising two side frames, the bottoms of the two side frames are connected with connecting pieces;

[0007] The tops of the two side frames are formed with mounting grooves, in which U-shaped brackets are arranged. The U-shaped brackets include two pressing plates, the sides of which are in contact with the sides of the fireproof and heat-insulating glass, and are used to support the fireproof and heat-insulating glass.

[0008] Preferably, the U-shaped support also includes a fireproof sealing pad, a first elastic member is connected between the fireproof sealing pad and the pressure plate, a fixing plate is arranged on the outer side of the fireproof sealing pad, and the fixing plate is fixed to the side frame;

[0009] A second elastic member is connected between the fixing plate and the pressing plate;

[0010] An arc-shaped elastic plate is fixed on the inner side of the fixed plate, and the opening side plate of the arc-shaped elastic plate is in contact with the pressing plate;

[0011] The outer side of the arc-shaped elastic plate is filled with fire-expanding material.

[0012] Preferably, a support member is fixed to the inner side of the top side plate of the side frame, and the side surface of the support member is in contact with the side surface of the fireproof and heat-insulating glass.

[0013] Preferably, the connecting piece is made of heat-insulating rubber.

[0014] Preferably, the arc-shaped elastic plate is formed by bending a metal plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The heat-insulating fireproof U-shaped bracket is provided with a U-shaped bracket. When a fire occurs or it is exposed to high temperature, the heat will be transferred to the fire-expanding material through the fixed plate. The fire-expanding material will expand when heated. The fire-expanding material on the outer side of the arc-shaped elastic plate will generate a squeezing force on the top and bottom of the arc-shaped elastic plate after expansion, causing the arc-shaped elastic plate to deform inwardly. When the side plates of the opening of the arc-shaped elastic plate move toward each other, a squeezing force is generated on the pressure plate, thereby causing the pressure plate to squeeze the fireproof and heat-insulating glass, thereby achieving stable support for the fireproof and heat-insulating glass, and effectively preventing the fireproof and heat-insulating glass from falling off.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] This solution is applied to heat-insulating fire-resistant windows to support fire-resistant and heat-insulating glass.

[0022] like Figure 1-Figure 2 As shown, the utility model provides a technical solution: an insulating fireproof U-shaped bracket, comprising two side frames 1 supported by stainless steel materials, the surfaces of the side frames 1 are sprayed with insulating paint and fire-resistant paint to form insulating layers and fire-resistant layers, and a connector 2 made of insulating rubber material is connected to the bottom of the two side frames 1. The connector 2 has a certain elasticity, so that it can not only block heat conduction but also prevent the connector 2 from squeezing the fireproof insulating glass 3 due to overall deformation, thereby preventing the fireproof insulating glass 3 from being damaged by pressure.

[0023] A mounting groove is formed on the top of the two side frames 1, and a U-shaped bracket is arranged in the mounting groove, such as Figure 2 As shown, the U-shaped bracket includes two pressure plates 402, which can be made of rubber material. It can be understood that after installation, the side of the pressure plate 402 is in contact with the side of the fire-proof and heat-insulating glass 3 to support the fire-proof and heat-insulating glass 3.

[0024] like Figure 2 As shown, the U-shaped bracket also includes a fireproof sealing pad 401, a first elastic member 403 is connected between the fireproof sealing pad 401 and the pressure plate 402, a fixing plate 404 is arranged on the outside of the fireproof sealing pad 401, and the fixing plate 404 is fixed to the side frame 1, and a second elastic member 405 is connected between the fixing plate 404 and the pressure plate 402, so that a mounting groove is formed between the fixing plate 404, the side frame 1, the pressure plate 402 and the second elastic member 405;

[0025] An arc-shaped elastic plate 407 formed by bending a metal plate is fixed to the inner side of the fixed plate 404. The arc-shaped elastic plate 407 is preferably made of stainless steel, and the open side plate of the arc-shaped elastic plate 407 is in contact with the pressure plate 402. The area formed by the installation groove and the outer side of the arc-shaped elastic plate 407 is filled with fire-expanding material 406.

[0026] In order to increase the supporting stability of the fireproof and heat-insulating glass 3 , a supporting member 5 is fixed on the inner side of the top side plate of the side frame 1 , and the side surface of the supporting member 5 is in contact with the side surface of the fireproof and heat-insulating glass 3 .

[0027] For the supplement of this solution, first install Figure 2The fireproof and heat-insulating glass 3 is installed by the connection method. When a fire occurs or it is exposed to high temperature, the heat will be transferred to the fire-expanding material 406 through the fixing plate 404. The fire-expanding material 406 will expand when heated. The fire-expanding material 406 on the outside of the arc-shaped elastic plate 407 will generate a squeezing force on the top and bottom of the arc-shaped elastic plate 407 after expansion, causing the arc-shaped elastic plate 407 to deform inwardly. When the open side plates of the arc-shaped elastic plate 407 move toward each other, they generate a squeezing force on the pressure plate 402, thereby causing the pressure plate 402 to squeeze the fireproof and heat-insulating glass 3, thereby achieving stable support for the fireproof and heat-insulating glass 3.
