Abstract
The utility model relates to a prevent fire door block structure, including the fire door body, trunk and hot melt board, trunk fixed mounting is in fire door body rear side upper portion, trunk lower extreme opening, and the hot melt board closing cap is equipped with fire-resistant sand in trunk open end department, the trunk intussuseption. Adopt the technical scheme of the utility model, when the conflagration breaing out, make fire-resistant sand leak out after melting through triggering hot melt plate and hot melt plug, it spreads to the peripheral adjacent region of fire door to have blocked the intensity of a fire, promoted the fire door body and blocked the performance that the intensity of a fire spreads, the burning source that makes the interior space internal combustion lacks the circulation air that comes from outside, effectively slowed down the intensity of a fire and spread the trend, prevent simultaneously that the intensity of a fire from spreading to other adjacent interior spaces or open air through narrow and small crack, won the valuable time for rescuing the conflagration, avoided causing bigger economic loss, the utility model has the advantages of simple structure, the fire prevention cuts off effectually.
Description
Technical Field
The utility model relates to a fire engineering technical field especially relates to a prevent fire door block structure.
Background
The door usually is the passageway between each inside adjacent indoor space of connection building or the passageway of connecting building indoor space and outdoor space, if the conflagration takes place in the building, corresponding door then plays the effect of cutting off the fire source to prevent the intensity of a fire from spreading to another adjacent indoor space from building indoor space or from building indoor space to outdoor, prevent to produce bigger economic loss, present fire door usually adopts fire-resistant, high temperature resistant material to make, has certain effect to stopping intensity of a fire to spread, however, because fire door itself is limited in size, the effect of blocking to the intensity of a fire is also corresponding very limited, often do not play sufficient effect of blocking when the intensity of a fire is great.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a prevent fire door block structure.
The utility model provides a prevent fire door block structure, including the fire door body, trunk and hot melt board, trunk fixed mounting in fire door body rear side upper portion, trunk lower extreme opening, the hot melt board closing cap in trunk opening end department, the trunk intussuseption is equipped with fire-resistant sand.
The fireproof door body comprises a door frame and door plates which are covered on the front side and the rear side of the door frame, and the fireproof sand is also filled in a cavity between the door plates and the door frame.
The material of the refractory sand is quartz sand.
The door frame left and right sides all is provided with a plurality of hourglass hole, and every hourglass hole drill way department shutoff has the hot plug.
The hot melt plug is made of polyethylene or polyvinyl chloride.
The door plate is made of 408-grade stainless steel.
The material of the hot melt plate is polyethylene or polyvinyl chloride.
A melt plate is bonded to the trunk at the open end.
The volume of the trunk is 20-35% of the volume of the fireproof door body.
The beneficial effects of the utility model reside in that: by adopting the technical proposal of the utility model, when a fire disaster happens, the hot melting plate arranged at the opening end of the trunk is melted under the high temperature condition, thereby the fire-resistant sand in the trunk can be poured out to block the fire from spreading to the adjacent area around the fire door, in addition, along with the melting of the hot melting plug blocked at the hole opening of the hourglass hole, the refractory sand filled in the fireproof door body also leaks out and is filled in the door gap at the installation position of the fireproof door body, thereby improving the performance of the fireproof door body for blocking the fire spreading, leading the fire source burning in the indoor space to lack ventilation air from the outside, effectively slowing down the fire spreading trend, prevent simultaneously that the intensity of a fire from stretching to other neighbouring indoor spaces or open air through narrow and small crack, won the valuable time for rescuing the conflagration, avoided causing bigger economic loss, the utility model has the advantages of simple structure, the fire prevention cuts off effectually.
Drawings
Fig. 1 is a front view of the present invention;
fig. 2 is a right side view of the present invention.
In the figure: 1-fireproof door body, 2-trunk, 3-hot melt plate, 4-refractory sand, 11-door frame, 12-door plate and 13-sand hole.
Detailed Description
The technical solution of the present invention is further explained with reference to the accompanying drawings, but the claimed protection scope is not limited to the above;
the utility model provides a prevent fire door block structure, as shown in figure 1, figure 2, including the fire door body 1, trunk 2 and hot melt board 3, 2 fixed mounting of trunk are in 1 rear side upper portion of the fire door body, 2 lower extreme openings of trunk, and 3 closing caps of hot melt board are in 2 opening end departments of trunk, and trunk 2 intussuseption is equipped with fire-resistant sand 4.
Further, the fireproof door body 1 comprises a door frame 11 and door plates 12 covering the front side and the rear side of the door frame 11, and the fire-resistant sand 4 is filled in a cavity between the door plates 12 and the door frame 11. The material of the refractory sand 4 is preferably quartz sand. The left side and the right side of the door frame 11 are provided with a plurality of sand leakage holes 13, and the orifice of each sand leakage hole 13 is plugged with a hot melt plug. The material of the hot melt plug is polyethylene or polyvinyl chloride. Generally, polyvinyl chloride is melted within the range of 150-200 ℃, polyethylene is melted within the range of 120-136 ℃, and when a fire occurs, the existing objects can reach the corresponding temperature range after being burnt, so that the trunk is started to be opened.
Further, the door 12 is made of 408 grade stainless steel. The stainless steel with the grade of 408 has excellent heat resistance, and can further block the spread of fire. The material of the melt plate 3 is polyethylene or polyvinyl chloride. The melt plate 3 is adhered to the open end of the trunk 2. The volume of the trunk 2 is 20 to 35 percent of the volume of the fireproof door body 1.
By adopting the technical proposal of the utility model, when a fire disaster happens, the hot melting plate arranged at the opening end of the trunk is melted under the high temperature condition, thereby the fire-resistant sand in the trunk can be poured out to block the fire from spreading to the adjacent area around the fire door, in addition, along with the melting of the hot melting plug blocked at the hole opening of the hourglass hole, the refractory sand filled in the fireproof door body also leaks out and is filled in the door gap at the installation position of the fireproof door body, thereby improving the performance of the fireproof door body for blocking the fire spreading, leading the fire source burning in the indoor space to lack ventilation air from the outside, effectively slowing down the fire spreading trend, prevent simultaneously that the intensity of a fire from stretching to other neighbouring indoor spaces or open air through narrow and small crack, won the valuable time for rescuing the conflagration, avoided causing bigger economic loss, the utility model has the advantages of simple structure, the fire prevention cuts off effectually.
