Abstract

The utility model discloses a self-lock plastic-steel keel which can be used for decorating ceilings and baseboards indoors and partition, comprising a fixing keel and a pressure locked keel, wherein, the fixing keel and the pressure locked keel are respectively provided with a groove and combining teeth which can be engaged with each other, and the bottom face of the fixing keel is provided with a sealing gasket. The self-lock plastic-steel keel has self-locking and adjustable functions and the advantages of good sealability, high combination strength, and simple manufacturing process. When used as a building decorative component, the self-lock plastic-steel keel can save time and material, and shorten construction period and ensure construction quality. The self-lock plastic-steel keel is particularly suitable for the interior decoration of houses and ships.

Description

Self-lock plastic-steel keel

The utility model relates to the building decoration member, is a kind of prefabricated member keel.

At present, at used keel such as interior decoration ceiling, skirting board and partitions, generally adopt timber or metallic support to combine, need during construction to fix with nail or screw, need a large amount of timber and nail, screw or viscose glue, its assembly technology is loaded down with trivial details, time-consuming, take material, the cost height, and the construction period is long, difficult quality guarantee.

The purpose of this utility model is to provide a kind of main self-locking member keel that can fix by self structure, makes to reach member and can give system, and technology is simple during site assembly, increases work efficiency economical with materials.

The utility model that achieves the above object is by fixedly keel and pressure lock keel constitute.Fixedly the keel cross section is approximate I-shaped, upwards has a groove from the bottom surface on its vertical wall, and is shaped on one section from bottom to top symmetrically in conjunction with tooth on the two sides of this groove.Fixedly the end face and the bottom surface of keel are the plane, but because fluting, the separated into two parts of then going to the bottom respectively is embedded with a liner in these two-part bottom surface both sides.Press lock keel cross section to be inverted T-shaped, on its vertical wall, begin to have a groove downwards from the top, and this two vertical walls that separate outside be shaped on from the top down with fixing keel on to combine tooth snappable in conjunction with tooth; Each forms the flange that raises up to press lock keel bottom surface both side edges at inverted T-shaped.

Utilize the utility model to make the house counter ceiling, make skirting board or when cutting off, earlier with key screw fixedly keel be fixed on roof or the wall with the form of its groove mouth downward (outwards), then pressing the lock keel to go into this fixedly in the groove of keel for chimeric one section, put in the horizontal bottom of pressing lock keel both sides again and mix decorative plate respectively, firmly compress the lock keel and get final product till the three is close to until making fixedly bottom surface, decorative plate and the pressure of keel lock the keel upper surface.

By on see that the utility model is simple in structure, but the member standardization is simplified construction technology, save material, from aspect of performance, because of the utility model is to use in conjunction with tooth interlock mode, have enough intensity, but and the free adjustment distance, to adapt to the dalle of different-thickness; Moreover, because of be fixed keel and press the lock keel closely to compress of sheet material, and also have liner, then good airproof performance during especially for air-conditioned room, has energy-saving effect.The utility model is compared with commonly used timber keel or metal keel, has significant advantage: save artificial aspect, the utility model saves artificial 9/10 than with the timber keel; Than saving artificial 3/4 with the metal keel; Aspect the construction period, the utility model is than shortening construction period 4-10 doubly with timber or metal keel, and its economic benefit can be multiplied.

The utility model can also obtain further instruction from the following drawings and embodiment.

Fig. 1 is the utility model cross section structure sectional view.

Shown in figure, fixedly keel 1 its cross section in the present embodiment is approximate I-shaped (vertically being strip), for can this fixedly keel 1 be fixed on roof or the wall, and for inlaying pressure lock keel 5 usefulness, special upwards opening from bottom surface on its vertical wall 2 is shaped on a groove 3, and on the two side of this groove 3, be shaped on symmetrically from bottom to top one section in conjunction with tooth 4(from vertically being seen as tooth bar), owing to opened groove 3, then bottom surface 7 is with regard to separated into two parts, in the present embodiment, each chimericly has a sealed ubber strip 8 in bottom surface divided into two parts 7 both sides.Then so fixedly keel 1 can penetrate and be fixed on roof or the wall with the bottom of screw from groove 3.See by figure, press the cross section of lock keel 5 to be inverted T-shaped (it vertically also is strip), for making these pressure lock keel 5 have certain elasticity, begin to have a groove 11 on its vertical wall downwards from the top, the vertical wall of then pressing lock keel 5 is separated into two parts also, be shaped on from the top down on these vertical wall two lateral surfaces divided into two parts can with fixing keel 1 in conjunction with tooth 4 mutually interlock in conjunction with tooth 6; Can be better and the decorative plate driving fit for the horizontal bottom 10 that makes its lower end, 10 both side edges respectively are shaped on the flange 9 that raises up in the bottom surface.

Fixedly keel 1 in the present embodiment and pressure lock keel 5 are all used flame retardant type PVC plastics extrusion molding, thus its lovely luster, acid-proof, alkali prevention, ageing-resistant.

Claims

1, a kind of self-locking Plastic-steel keel is characterized in that it by fixing keel 1 with press lock keel 5 to constitute,

A. fixedly keel 1 cross section is approximate I-shaped, on its vertical wall 2, upwards have a groove 3 from bottom surface, and on the two sides of this groove 3, being shaped on one section from bottom to top symmetrically in conjunction with tooth 4, each chimericly has a liner 8 in bottom surface divided into two parts 7 both sides;

B. press lock keel 5 cross sections to be inverted T-shaped, on its vertical wall, begin to have a groove 11 downwards from the top, and this two vertical walls that separate outside be shaped on from the top down with fixing keel 1 in conjunction with tooth 4 mutually interlock in conjunction with tooth 6; Each forms the flange 9 that raises up bottom surface 10 both side edges.
