Description

Improved wooden fire door structure

technical field

The utility model relates to a fireproof door, in particular to an improved wooden fireproof door structure capable of delaying combustion.

Background technique

Based on the consideration of fire safety, most of the current buildings use fire-resistant and heat-insulating fire safety doors, so that in case of a fire in the building, the fire safety door can be delayed when the fire safety door is closed, so as to effectively isolate the fire scene and prolong the life of personnel. Time to escape.

Under the condition of effectively isolating the fire scene, in order to avoid the heavy weight of the fire safety door, the general fire safety door structure is to form a hollow space between two door panels made of stainless steel, and directly set the fireproof foam in this space. , by virtue of the flame-retardant and heat-insulating properties of the fire-proof foam, the entire safety door can achieve a fire-proof effect.

Furthermore, the cost of stainless steel fire doors is expensive, and the effect of blocking flames is that the built-in blocking materials of the door panels are not tightly bonded and have gaps, which often cause overheating in a short time, and the flames burn through the gaps; and the fireproof foam material There are no protective measures in the safety door, so it may be broken due to poor vibration resistance during construction or transportation. During the safety test, the burning flame will conduct heat through the crack, causing the surface of the metal safety door to burn. Hot, affecting personnel escape.

Therefore, another kind of existing fireproof safety door is to utilize light fireproof filling material to replace described fireproof foaming material; The foam body, the fireproof foam body and the fireproof board are fixed together with an adhesive, which is suitable for being installed inside the fireproof safety door as a lining, so as to reduce the weight of the fireproof safety door.

In addition, expanded perlite is also used in the manufacture of fireproof fillers because of its good fireproof effect. Perlite is a glassy lava formed by the eruption of acidic magma, named for its pearly fissure structure. Expanded perlite is made by crushing and roasting perlite. Ordinary expanded perlite has better and more performance after hydrophobic treatment, and can be widely used in roof insulation, wall composite insulation, heat pipe insulation layer, and cold storage enclosure structure insulation layer application.

The manufacturing method of the expanded perlite can contain 65-80% perlite micropowder, 19-34% sodium silicate and other binders and 0.1-1% hydroxyl hydrogen-containing silicone oil and other hydrophobic agents by weight, or add synthetic fiber. The method adopts that the components are mixed by air flow and spray, and then shaped and dried to form a product. The product has low density and thermal conductivity, and the water repellency rate is over 98%. The service temperature is -78℃～650℃ and has high flexural resistance and toughness, so it can be used in humid environment.

Another method of producing expanded perlite is to introduce expanded perlite and air heated by the expansion chamber into the cooling and coating chamber, and use nozzles to spray water-repellent substances to simultaneously coat the expanded perlite. An inlet nozzle and a temperature sensor are arranged upstream of the nozzle to control the air flow and cooling temperature, so that the hydrophobic substance covering the expanded perlite can be at a suitable temperature before the expanded perlite is separated from the expanded gas.

Utility model content

The main technical problem to be solved by the utility model is to overcome the above-mentioned defects existing in the prior art, and provide an improved wooden fire door structure, so that the fire door can not only have a good fire resistance function, but also its weight can be reduced, and the manufacturing cost can be lowered. Low, and visually more aesthetically pleasing.

The technical scheme that the utility model solves its technical problem adopts is:

An improved wooden fire door structure is characterized in that it includes: a wooden door frame, which is provided with a space running through both sides of the wooden door frame; a first wooden door panel, which is arranged on one side of the space of the wooden door frame; An expanded perlite block is arranged in the space of the wooden door frame; a second wooden door panel is arranged on the other side of the space of the wooden door frame, so that the fireproof material block is located between the first and second wooden door panels .

Compared with the existing stainless steel fireproof safety door with general fireproof material inside, the structure of the utility model not only has better fireproof effect, but also has a lower weight than stainless steel, and at the same time has the visual warmth brought by wooden materials.

Detailed ways

Referring to shown in Fig. 1, the wooden fireproof door provided by the utility model, its manufacturing method is to manufacture a wooden door frame 1 in advance, and this wooden door frame 11 has at least one space that runs through both sides, and a side of this space is arranged earlier The first wooden door panel 11 shields one side of the space by the first wooden door panel 11, and then the wooden door frame 1 is placed on the working platform 3 of the die-casting machine 4, so that the first wooden door frame 11 contacts the working platform downward.

In addition, the expanded perlite material is processed into an expanded perlite block 2 corresponding to the space of the wooden door frame 1, and the expanded perlite block 2 is put into the space, and the expanded perlite block 2 is paired by a die-casting machine 4. Give die-casting, make it extrude into dense block (as shown in Figure 2) in the limited space of wooden door frame, cover and fix on the other side of the space of wooden door frame 1 with the second wooden door panel 12 (as shown in Figure 2) Shown in Fig. 3), finish a fireproof door at last, and this fireproof door can cooperate hinge 5 and handle (as shown in Fig. 4) and be provided in the door channel that is installed in building.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model, All still belong to within the scope of the technical solution of the utility model.
