A preparation process of an indoor fire hydrant for fire fighting and escape in an office building comprises the steps of firstly, building a steel bar framework to form a cavity 6, arranging a template, pouring concrete, and then standing to form a concrete wall surface 1; laying hollow bricks through a level meter and a manual mode, filling vacuum insulation panels in the hollow bricks, connecting the hollow bricks through insulation mortar, and then standing; inserting the mounting seat 16 and the connecting pipe before the heat insulation mortar is solidified, and waiting for solidification; step four, installing an accommodating cavity 7 with a rotating door 4 in the cavity 6; bonding an asbestos layer 2 on the heat insulation wall body through viscose, penetrating a glass support rod into the asbestos layer 2, enabling a vertical groove in the asbestos layer 2 to be matched with an installation seat 16, and enabling the installation seat 16 to be located at the lower end of the vertical groove; sixthly, the ceramic tiles 3 are bonded on the adjacent mounting seats 16 through concrete for fixing; seventhly, placing an oxygen bottle and an oxygen mask in the cavity 6; step eight, installing a fire hydrant 8 in the accommodating cavity 7, wherein the fire hydrant 8 is connected with a water outlet pipe 9 through an adjusting valve 10, and the adjusting valve 10 is connected with a connecting pipe; step nine, arranging a sliding chute on the bottom surface of the cavity 6 through a cutting machine, embedding a rolling ball 15 and a ball seat 14 of the vertical hinged door 5 into the sliding chute, communicating an outlet pipe 12 on the vertical hinged door 5 with a communication part between the regulating valve 10 and a connecting pipe, and communicating an inlet pipe 13 with the regulating valve 10; step ten, installing a clamping piece I on the vertical hinged door 5 in a screw connection mode, and installing a clamping piece II on the inner wall of the through hole in a screw connection mode; and step eleven, cleaning, placing equipment such as a fire extinguisher and the like in the accommodating cavity 7, and closing the rotating door 4 and the horizontally opened door 5.
When people need use indoor fire hydrant to carry out emergency in the conflagration emergency, people can open revolving door 4 to unscrew governing valve 10, make governing valve 10 inside switch on, make in water in the fire hydrant 8 can flow into governing valve 10, make water can leave from outlet pipe 9.
Then, people open the first clamping piece and the second clamping piece to push the vertical hinged door 5 open, the vertical hinged door 5 rolls in the ball seat 14 through the balls, thereby smoothly sliding in the chute, then people hide in the cavity 6 and close the vertical hinged door 5 again, when the vertical hinged door 5 is closed, the elastic water absorption layer 11 can fill the gap between the vertical hinged door 5 and the through opening, as the water outlet pipe 9 discharges water, the water falls onto the inner bottom surface of the containing cavity 7 and flows into the elastic water absorbing layer 11 through the through hole, so that the elastic water absorbing layer 11 can keep moist to effectively block the smoke, at the same time, the inlet pipe 13 and the outlet pipe 12 enable the circulation and replacement of the cooling water inside the vertical hinged door 5, the temperature of the cooling water in the vertical hinged door 5 is always kept in a low state, and the temperature rise in the cavity 6 caused by the fact that the vertical hinged door 5 cannot resist high temperature is avoided.
Thermal-insulated wall body then effectively strengthens the thermal-insulated effect of hollow fragment of brick further through its inside vacuum insulation panel for the temperature in the cavity 6 can carry out the separation through thermal-insulated wall body, avoids 6 inside air of cavity and the air in the external world to take place the heat exchange, rising temperature then, and if when the temperature rise in the cavity 6, people can open the oxygen cylinder again, wears the oxygen mask and breathes, avoids appearing breathing difficulty and the problem of sudden death.
When the external fire is serious, flame burns on the ceramic tile 3, the regulating valve 10 is opened, water can flow into the asbestos layer 2 in the connecting pipe, so that the ceramic tile 3 cannot be burnt out in a short time, when the ceramic tile 3 is burnt by high temperature and then cracks and falls off, the water-absorbing asbestos layer 2 cannot be effectively supported by the ceramic tile 3, the viscose is melted under the high-temperature condition because the water-absorbing asbestos layer 2 is connected with the heat insulation wall body through the viscose, and the connecting pipe is positioned at the upper end of the asbestos layer 2, so when the asbestos layer 2 absorbs water, the weight of the asbestos layer 2 is light, when the supporting rod is supported, the asbestos layer 2 inclines and falls from top to bottom, and when the connecting pipe falls down, the supporting rod inside the asbestos layer is damaged and can be effectively coated on a burning object to extinguish, so that the area near the indoor fire hydrant 8 can extinguish, simultaneously the water in the connecting pipe can continue to spout and fall on asbestos layer 2 and moisturize and put out a fire for when the fire fighter need use this fire hydrant to put out a fire, the serious problem of near this fire hydrant conflagration condition can not appear, makes things convenient for the fire fighter to use, does and carries out effective protection to the people who hides in the cavity 6.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
