Description

Composite door frame

Technical Field

The present invention relates to doors for space division or closure of building openings, and more particularly to an improved composite door frame.

Background

In the prior art, most of the wood door frames used in large numbers are formed by compounding multiple layers of wood materials. The inner side of the door frame is generally covered with a decorative layer or a paint layer, and the door frame is exposed and ventilated and has certain waterproof and moisture-resistant capabilities; but the outside of the door frame is in direct contact with the wall or the ground and is not generally treated. Because these synthetic wooden materials, such as solid wood multilayer, medium fiber board, etc., have strong hygroscopicity and poor moisture resistance, when the door frame made of these materials contacts water vapor, the whole door frame will swell and go moldy when meeting water vapor, resulting in the serious quality problems of the door frame such as mold and decay.

The chinese utility model with application number 200520113558.7 discloses a scheme of a toe guard, namely, the lower end of the door frame body is provided with a waterproof toe guard. The scheme can effectively prevent the wood door frame ground feet from being soaked when water is stored in a room, but has no effect on the invasion of water vapor from the place where the door frame contacts with the wall body.

In the south, the wall emits water outwards in the south. Under the circumstances, solving the moisture-proof problem of the wooden composite door frame becomes a very interesting technical problem.

Disclosure of Invention

The utility model aims at providing a can thoroughly keep apart the dampproofing compound door frame of door frame periphery steam invasion.

In order to achieve the above object, the utility model provides a composite door frame, including a door frame main part, the door frame main part include two munitions and one and be used for connecting the horizontal frame of two munitions, the munition with horizontal frame form by the different material layer complex more than two-layer and, the munition with any one in the horizontal frame all includes an outside layer of being made by well fibreboard, the lateral surface coating on outside layer has waterproof paint, the munition with two vertical terminal surfaces of any in the horizontal frame all coat and have waterproof paint.

Preferably, the door frame further comprises a sideline arranged on one side of the door frame main body in the thickness direction, the sideline comprises a peripheral part partially covering the door frame main body, the peripheral part is made of medium density fiberboard, and the side surface of the peripheral part facing the door frame main body is also coated with waterproof paint.

Preferably, either one of the mullion or the transom includes an inner layer made of a medium density fiberboard, and a PVC film is disposed on a visible light surface of the inner layer.

Preferably, the inner side of the door frame main body is provided with a door stop strip, and the door stop strip is mainly made of a medium density fiberboard.

Preferably, the thickness of the inner and outer layers is in the range of 5 mm to 1 cm.

Preferably, the peripheral portion has a width of 4 to 9 cm.

It is obvious by above-mentioned scheme, the lateral surface coating on outside layer has waterproof paint, the munnion with two vertical terminal surfaces of any in the horizontal frame all coat with waterproof paint, and every place all around door frame and ground, wall contact all are equipped with waterproof paint promptly, and this paint forms in the outside of door frame, and the water vapor invasion of ground and wall body is directly prevented as the waterproof barrier layer of door frame, very big improvement the humidity resistance of compound door frame.

In addition, either of the mullions or the transoms includes an outer layer made of a medium density fiberboard. The physical properties of well fibreboard is fabulous, and the material is even, and is the first-selected substrate that carries out water proof coating, so by well fibreboard as bearing waterproof paint's outside layer can make waterproof paint more firm, guarantee the longer life of door frame.

To sum up, the utility model discloses a compound door frame has advantages such as the dampproofing ability is good, the product is durable relatively.

Detailed Description

The utility model discloses a description about door frame position, except special explanation, all use the operating condition that the door frame was installed in the door opening as the benchmark, the basic point is the geometric center in the space that the door frame surrounded.

Fig. 1 is a schematic perspective view of the composite doorframe of the present invention; fig. 2 is an exploded view of fig. 1. The composite doorframe 1 comprises a doorframe body composed of two mullions 10 having substantially the same structure and a transom 20 for connecting the two mullions. The mullion 10 and transom 20 are made of two or more layers of different materials. Both longitudinal end faces 101 of either of the two stiles 10 are coated with waterproof paint. Therefore, when the door frame is installed, special attention or marking of which longitudinal end of the vertical frame contacts the ground is not needed, so that the installation process is more convenient; in addition, waterproof paint can isolate the frame that the steam invaded from the terminal surface. Both longitudinal ends 201 of the horizontal frame 20 are also coated with waterproof paint. At the top edge of the door frame main body, even if two longitudinal end faces of the transverse frame directly contact the wall body, the waterproof paint can also isolate water vapor from invading the frame body from the end faces.

Fig. 3 is a cross-sectional view of the composite doorframe of the present invention; fig. 4 is a cross-sectional view of the composite doorframe with the addition of a border wire. Fig. 3 and 4 illustrate the hierarchical structure of the composite door frame in a horizontal cross-section of the mullion 10, and are applicable to not only the mullion 10 but also the horizontal mullion 20. Fig. 3 and 4 are cross-sectional views on a vertical plane for the cross frame 20. In this embodiment, the mullions 10 and transoms 20 are substantially identical in construction, except for their orientation and length.

Referring to fig. 3, the mullions 10 respectively include, from the outside inward: an outer layer 11 made of a medium density fiberboard, a core layer made of a multilayer board, and an inner layer 13 made of a medium density fiberboard. The layers are bonded together by a cold pressing process. The outer side 111 of the outer layer is coated with a water-resistant paint. Thus, when the mullion outer side 111 contacts the wall, the waterproof paint can isolate the ingress of moisture from the outer side into the frame. The light-viewing surface 131 of the inner layer 13 is provided with a PVC film. Thus, the PVC film can be used as a decorative surface and a waterproof layer. The thickness d2 of the inner layer 13 and the thickness d1 of the outer layer 11 are in the range of 5 mm to 1 cm. Therefore, the door frame with better physical performance can be obtained, and the manufacturing cost can be controlled.

Door stop strips 14 are also provided on the inside of the inner layer 13 as required. The barrier strip is mainly made of a medium density fiberboard, and the light-viewing surface thereof is also covered with a PVC film, which has the same function as that of the inner layer light-viewing surface 131.

Referring to fig. 4, the composite doorframe 1 further comprises a sideline 15 provided on any side of the doorframe body in the thickness direction. In this figure, the insert portion 152 of the border has not yet been inserted into the border mounting groove 121. The border 15 includes a peripheral portion 151 that partially covers the doorframe main body. The peripheral portion 151 is made of a medium density fiberboard, and its side 151-1 facing the door frame body is also coated with waterproof paint. The waterproof paint can isolate water vapor from invading into the sideline from the side surface. The peripheral portion 151 has a width w1 of 4 to 9 cm so that the overall door frame is relatively aesthetically pleasing.

The present invention is not limited to the above embodiments, and the above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
