Metal fireproof door explosion-proof structure

The invention relates to a metal fireproof roll door explosion-proof structure, in particular to an explosion-proof metal fireproof roll door structure, thereby strengthening the combined compressive strength between the metal fireproof roll door and the track, thereby achieving the explosion-proof requirement.

According to the general fire door installation, the main purpose is to prevent the rapid spread of fire in buildings. Therefore, in the "Technical Rules for Buildings", it is mandatory to provide firewalls, fire slabs and fire doors and windows to separate compartments. The structure of the door can be roughly divided into two types, one is a roll-type fire-proof roll door, such as the M415975 patent case; the other is a metal fire-proof roll door composed of a plurality of roll-up door hinges, such as M469367, M480587 The patent case is.

Since the roll-up type fire-proof roll door itself is a roll screen composed of fireproof cloth, it can not be used as a control for opening and closing the door. It can only be put down when the fire occurs, so as to block the spread of the fire; The fireproof cloth used in the fireproof roll door is a softer material. Therefore, when lifting and lowering operations, it must be guided by the limit of the two sides of the track, and through a track clamp with a press function in the track to provide the After the roll-up type fireproof roll door is lowered to reach the fixed position, the roll-type fireproof roll door is fixed by interlocking the clamped seat of the track clamp to prevent the fireproof roll door from loosening. Take off the situation and form a gas-tight effect to block the turbulence of the heat-insulating gas (the relevant technical content can be referred to the M415975 patent); as mentioned above, the roll-type fire-rolling door has no anti-theft and control access control functions, so it cannot be universally set. All in the building region.

Therefore, in places where there is control of access control in buildings, metal fireproof rolling doors must be used. However, metal fireproof rolling doors provide thicker tracks on the sides of the metal fireproof rolling door. The width of the guiding opening is relatively widened, and the inside of the rail used for the metal fireproof rolling door does not have any airtight and pressing mechanism, so that there is a gap between the metal fireproof rolling door and the track. In addition to the big problem, when the metal fireproof rolling door is at a high temperature, it is easy to be deformed and derailed, resulting in the metal fireproof rolling door not completely effective in stopping the turbulence of the heat source and the smoke, and reducing the original It has the function of blocking the spread of smoke from fire.

In order to solve the above-mentioned shortcomings, the inventor of the present invention proposed the M509844 and M507965 patent cases, but there are still some shortcomings, that is, the gap between the metal fireproof rolling door and the track can block the turbulence of the hot gas smoke. However, when the metal fireproof rolling door is subjected to gas explosion or external pressure (such as typhoon and strong wind), it is still difficult to meet the requirements of explosion protection.

In view of this, the inventor of the present invention has finally completed the metal fireproof roll door explosion-proof structure of the present invention after numerous research and improvement, that is, the object of the present invention is to provide an explosion-proof metal fireproof roll door structure, thereby strengthening the metal fireproof roll. The combined compressive strength between the door and the track, which in turn meets the requirements for explosion protection.

It is made in the rail 2 without derailing, thereby exerting an explosion-proof effect; when the metal fireproof rolling door 1 is wound up, the metal fireproof rolling door 1 no longer presses the pressing portion 321 of the movable rod piece 32. The tension spring S will pull the upper link group A1 and the lower link group A2 to pull back the movable rod piece 32 inwardly with its recovery elastic force, and the convex block 39 will shift out of the metal at this time. The fixing hole 102 of the fire shutter 1 is fired.

In summary, the fireproof roll door explosion-proof structure of the present invention utilizes the length of the first limit portion of the track to extend inwardly to a position where the convex block is engaged with the fixing hole of the side, so that the first The end of the limiting portion abuts against the outer periphery of the protruding block, thereby strengthening the compressive strength of the joint between the metal fireproof rolling door and the track, thereby achieving the explosion-proof requirement, so that the missing of the formula can be effectively solved; The technical means is unprecedented, and the invention has the novelty and progressive requirements of the patent.

The specific embodiments of the present invention are intended to be illustrative only and not to limit the scope of the present invention to the above embodiments, without departing from the spirit of the invention and the following claims. In the case of various changes made, it is still within the scope of the invention.
