Description

Fireproof wooden door frame

This creation belongs to the field of fireproof building materials, in particular, it relates to a fireproof wooden door frame, which is formed by setting an inner frame behind an outer frame to form a double-layer household block, and then using a plurality of barrier plates to correspond to the The joint of the outer frame is to block those who close their joints, so as to improve the overall structural strength and fire prevention effect.

In recent years, due to the frequent spread of fire incidents in various public places, public safety awareness has risen. Public places are areas where people come and go frequently. According to the current public safety regulations, the decoration materials used by them all have certain fire protection performance. Requirements, and for different public safety areas, the fire doors installed also have different levels of specifications; and the building codes for fire doors are set to effectively block the rapid spread of fire sources in the event of a fire. In fact, At present, relatively low-grade fire doors, that is, fire doors used in general homes, can only withstand the fire attack for a relatively short time, and may not even have enough time to withstand high temperatures to prevent the fire door from deforming, resulting in a large amount of smoke from the fire door. The gaps in the escaping caused obstacles during evacuation, especially those with physical and mental disabilities cannot escape in a short time, so the design of fire doors must also have a solid structure, good heat insulation, smoke prevention and other effects, usually with The solid and strong security can effectively block the high temperature, high heat and thick smoke when a fire accident occurs, prevent the fire from spreading and extend the time for people to escape.

In fact, the general fire doors on the market, in addition to the door leaf, of course also include one of the door frames with fire protection design, such as: Republic of China Patent Bulletin No. M432679 "Composite Refractory Sandwich Panel and Its Sheet Structure", which discloses a kind of manufacturing Convenient, high strength, convenient surface decoration, can be directly nailed into the connected composite refractory sandwich board, which is formed by n layers of refractory board and n-1 layer of wood material board layered and pasted, n is an integer equal to or greater than 2 . A layer of wood material can also be pasted on one or both sides of the composite refractory sandwich panel. However, when this kind of multi-layer structure composite refractory sandwich panel is actually used, there are still many deficiencies that need to be improved. The multi-layer structure composed of plates are all fixed by screws from the thickness side. When the fixing element (or drilling element) is worn After being inserted into the multi-layer board, the assembly direction of the multi-layer board and the fixing element is parallel, which is easy to cause structural damage. Furthermore, due to the different materials of each layer of the multi-layer board, there may be different deformation and distortion between the layers, especially the type of board When the door leaf used as a fire door is cut or otherwise processed, the mechanical strength is greatly reduced. Because of this, it is also easy to lose its fire resistance during a fire and affect the fire protection effect.

However, most of the door frames currently used for fire doors are frame-shaped structures made in conjunction with fire doors. The long structure (door frame material) made of fire-proof materials is made by cutting and assembling; For the purpose of aesthetics, the end of the door frame material is made into a corresponding 45-degree inclined surface during assembly. After the inclined face is joined, the side of the one door frame material is fixed with a fixing member; however, the inclined surface is formed During the cutting process, the gaps after assembly will be more or less due to the machining tolerances. If these gaps cannot be effectively closed, it will cause thick smoke to gradually penetrate from there and affect the escape.

However, in view of the above-mentioned shortcomings in practice, the inventors studied and improved the aforementioned shortcomings. The author designed a fireproof wooden door frame based on this. In addition to the double-layer household block generated by the double frame, it has both aesthetic and fireproof effects; Furthermore, the use of a plurality of barrier plates corresponding to the joints of the outer frame to block and seal the seams generated during assembly, not only can improve the overall structural strength, but also effectively improve the fire protection effect, especially to solve The problem of smoke penetration.

One purpose of this creation is to provide a fireproof wooden door frame that uses an outer frame and an inner frame that combine fireproof materials and wooden materials. After assembly, the surface is made of wood, and the inside is made of fireproof materials. The structure of the barrier; in addition, the use of multiple barriers at the junction of the outer frame to block and seal the seams generated during assembly, not only can improve the overall structural strength, but also effectively improve the fire protection effect, especially to solve the smoke The problem of penetration.

In order to achieve the above purpose, the fireproof wooden door frame of this creation includes: an outer frame, which is a rectangular frame surrounding structure formed by the combination of a first frame of wood and a pair of second frames, the pair of first frames and The outer periphery of the pair of second frames are covered with a fireproof material, and a block is protruded below the inner surface of the outer frame adjacent to the front surface, and the fireproof material is covered with a front surface, inner surface and back surface of the outer frame Wooden surface material, and the household block is provided with a ring groove opposite to the inner surface of the outer frame; an inner frame is a rectangular frame-shaped structure formed by the combination of a third skeleton and a pair of fourth skeletons of wood, And the periphery of the inner frame corresponds to the ring groove and is provided with a ring protrusion to install the inner frame in the outer frame to form a double-layer household block; and at least four barrier pieces, which are fireproof It is made of materials, and the barrier plates are correspondingly arranged at the joints of the pair of first frames and the pair of second frames, so that the barrier plates block and close the seams formed by the joints of each group, and accordingly improve their Structural strength and fire resistance.

In an embodiment, a junction between the first skeleton and the second skeleton forms a first inclined plane and a second inclined plane, respectively, and each first skeleton is provided with a relative to the first inclined plane A pair of perforations, and each second frame is provided with a pair of fixing holes relative to the pair of perforations for screwing a pair of fixing members therein, so that the pair of first frames and the pair of second frames are assembled sequentially . Furthermore, the first inclined surface is provided with a first insertion hole between the pair of perforations, and the second inclined surface is provided with a second insertion hole between the pair of fixing holes, the first insertion hole and the second insertion hole An insertion groove is formed so that the insertion groove is perpendicular to the first inclined surface and the second inclined surface for assembling the barrier pieces. Moreover, a junction between the third frame and the fourth frame forms a third slope and a fourth slope respectively. However, when the inner frame of the present creation is assembled inside the outer frame, a fireproof fixing glue is filled between the ring groove and the ring protrusion. In addition, the ring protrusion is provided with a ring clamping groove opposite to the back of the outer frame, for providing an airtight rubber strip therein.
