1 and 2, the fire door frame assembly A according to the present invention includes a mixture 10 and a frame 20 through which the mixture 10 is sprayed.

Before describing the present invention, 'dancing' is a term used in a construction site, such as: 1. cracks or openings; 2. filling of cracks in walls or walls; 3. cracking of stones or bricks; In the present invention, the clearance or the space inside the frame, which is generated when the frame is coupled to a wall or the like, is referred to as a " space for dancing " Filling up the space for dancing is called 'dancing'. In addition, 'spraying' refers to spraying the paint finely and uniformly through the spray nozzle.

A fire door A1 is provided in a building or the like to prevent the spread of fire again and a frame 20 for forming a frame for installing the fire door A1 is provided on the wall A2 to have the fire door A1, The present invention relates to such a frame (20), which comprises a frame (20) and a mixture (10) provided in the frame (20).

Such a frame 20 may be formed in various shapes depending on the shape of the fire door, and the scope of the right should not be limited.

In addition, it is preferable that the frame 20 is provided with an interpolation part 23 which can cover the wall A2 on one side of the frame 20. However, it can be variously configured according to the shape of the frame 20, Can not be done.

The frame 20 of the fire door frame assembly A according to the present invention may be formed by forming the sandwiching space 21 as the frame 20 is coupled to the wall A2 or by forming the sandwiching space 21 inside the frame 20 In order to improve the refractory performance, the mixture 10 is sprayed with water and a coating agent, wherein the coating agent is an inorganic binder, a fireproof material, A mixture of a heat insulating aggregate, a cross-linking agent, a concrete admixture and a slaked lime.

More specifically, the inorganic binder constituting the coating material is precisely an inorganic binder,

In the present invention, it is preferable to use mainly clay or gypsum. However, it may be used as cement, sodium silicate, aluminum silicate, calcium silicate, etc., and when water is added, the chemical reaction takes place and the adhesive property is made. In the present invention, it is preferable that the inorganic binder is 10 to 80% by weight.

In addition, when water and an inorganic binder are excluded from the coating, the inorganic binder may be composed of 10 to 30% by weight. The inorganic binder reacts with water or carbon dioxide in the air to perform a curing reaction, The hard material serves as a binder.

Further, the fire-resistant and heat-insulating aggregate is preferably 10 to 80% by weight, more preferably 10 to 40% by weight. The refractory heat-insulating aggregate is mainly composed of volcanic ash (pearlite) and vermiculite, and is a material having fire resistance performance. Fillite, vermiculite, and slaked lime are produced at a high temperature (about 1500 ° C.) Can be equipped.

The cross-linking agent is comprised of 1 to 5% by weight, and is composed of pine rosin and artificial rosin, and when it is artificially rosin, it is mainly composed of petroleum resin emulsion and rosin ester emulsion. More specifically, the organic cross-linking agent enhances the adhesive force between the materials having heterogeneity and enhances the adhesive force on the metal surface. When the cross-linking agent is 5 wt% or more, the refractory performance is reduced.

The concrete admixture is composed of 0.1 to 5% by weight and determines the viscosity as an air entraining agent. Therefore, when the content is less than 0.1% by weight, the viscosity is low and it easily flows down, so that the dancing is not easy. When the content is more than 5% by weight, the viscosity increases but the fire resistance deteriorates. Therefore, the admixture may be an air entraining agent, a rapid-setting agent. By using retarder in accordance with temperature and season, it is possible to increase the amount of coating to increase moisture content and increase the aggregate amount, but since the viscosity is increased, an admixture is used.

If the amount of the slaked lime is 0.5 wt% or less, the hardening speed is lowered and the production time is increased. When the slaked lime is higher than 30 wt%, the hardening proceeds too fast and cracks are generated. .

In addition, the coating agent may further include an inorganic flame retardant. The inorganic flame retardant is composed of a phosphorus (P) -based or antimony-based inorganic flame retardant and is used as an additive to compensate for the lowering of the fire resistance due to the organic binder and the admixture.

Therefore, the above-mentioned components are mixed to form a coating, and this coating is compounded with water to form a mixture 10. After that, the mixture 10 is sprayed into the saturation space 21,

The coating agent and water are mixed at a weight ratio of 1: 0.4 to 1: 1.8. This is because when the content of water is 0.4 wt% or less, the fluidity is lowered, a load may be applied to the coating mechanism and the coating surface may become uneven, and when it exceeds 1.8 wt.

Also, the mixture 10 is sprayed to the dancing space at a thickness of 20 to 50 mm, and the mixture 10 can withstand the heat for more than 40 minutes, so that the refractory performance can be improved. That is, the thickness to be used for the fire door is 10 ~ 45mm and the thickness of fire resistance is 20 ~ 50mm which can show the fire resistance for more than 40 minutes. When compared with the current EPS lightweight cement slurry, The heat shielding performance of the fire door was secured for 2 hours, and the heat shielding effect was greatly improved.

In order to confirm the performance of the fire door frame assembly according to the present invention, fire resistance performance test by KS F 2257-1 was carried out. As a result, it was 120K higher than the reference average of 140K higher than the initial temperature, Also, it can be seen that it is not ignited when the prescribed surface pad is applied, does not pass through the crack gauge, and does not generate a flame on the non-heated surface, thereby excelling in the fire prevention effect.

Furthermore, as a result of the fire resistance performance test by FS F 2268-1, it can be seen that the cotton pad is not ignited when applied to the surface, and flame is not generated on the back surface for more than 10 seconds.

Since the weight percentage of the components used in the mixing step 100 has been described in detail with reference to the fire door frame assembly A, it is not necessary to limit the scope of the right.

It is preferable that the mixture 10 is sprayed in the space 21 of the frame 20 to a thickness of 20 to 50 mm in order to improve the refractory performance in the spraying step 200. This mixture is sprayed evenly on the frame A mono pump is used.

The mono pump is generally a pump for injecting and injecting air while pushing the mixture 10, and a rotary one-shaft eccentric screw pump is used to reciprocate the inside of the stator while rotating the rotor, (Mixture) that is filled with the space volume generated in the pump is a pump that is constantly fed to an infinite piston motion which is not broken by the rotation of the rotor and is uniformly jetted.

Therefore, by spraying through the mono pump, the mixture can be uniformly sprayed to the entire frame, thereby improving the fire resistance uniformly, thereby completely preventing the diffusion of the flame.

Furthermore, in the curing step (300), the natural curing at 25 ° C is allowed to proceed for about 8 hours, or the content of slaked lime and quick-setting agent can be increased to adjust to 2 hours to 8 hours. In winter, And intensity control so that it can be selected according to the season and circumstances.

The rotating shaft 551 is hinged about the rotating shaft 551. The rotating shaft 551 should be located below the center of gravity of the rotating shaft 53. The rotating shaft 551 will be described later, 55 will be described in more detail. The support 555 and the support 51 are connected to each other by an elastic body 57. The elasticity of the elastic body 57 allows the rotary body 55 to be elastically biased about the rotary shaft 551 do.

Therefore, when the horizontal frame is inserted into the vertical frame, the rotating body 55 of the fixing means is inserted into the rotating hole 53 in one direction of the rotating shaft 551, and by the elastic force of the elastic body 57, The rotating body 55 can be inserted into the rotating hole 53. When the rotating body 55 is rotated toward the inner side of the vertical frame by applying a force to the rotating body 55, the dead point 57A of the elastic body 57 (the dead point 57A means the elasticity 57) , And the rotating body 55 passing through the dead point 57A supports the inner surface of the vertical frame by the elastic force.

The switch bar 63 is further provided on the switch frame provided in the horizontal frame and the switch bar 63 is provided on the switch frame 63. [ Is protruded from the outer surface of the horizontal frame. It is further preferable that a locking protrusion 631 is provided at one side of the switch bar 63 to prevent the switch bar 63 from being released to the outside of the horizontal frame.

The other side of the switch bar 63 presses the switch projection 61 provided on the rotary shaft 551. As the switch bar 63 is moved, the switch projection 61 is pressed to the rotary shaft 551 The rotating body 55 is automatically rotated instantaneously as it passes through the dead point 57A of the elastic body 57 to support the inner surface of the vertical frame.
