Abstract

The utility model discloses an improved rabbet structure for reinforced floor, aiming to overcome the defects existing on the existing reinforced floors. The utility model is characterized in that: the cross section of a rabbet is an artwork composed of an upper arc line segment, a lower arc line segment and a straight line segment, and the upper arc line of the section of the rabbet contains a sawtooth projection; the cross section of a keyway is a groove which corresponds with the cross section artwork of the rabbet, and an upper arc line of the groove section includes a sawtooth concave which corresponds with the sawtooth projection on the upper line of the rabbet. The reinforced floor structured by the above scheme, because a sawtooth strip and a sawtooth groove are designed on the arc surface of the rabbet and the keyway, is effectively prevented from unlocking, and a triplet sawteeth strip and a triplet sawteeth concave obviously increase straining strength of combination of the floor. Proved in use, the improvement of the rabbet structure has a function of preventing floor surface from being deformed. The utility model is really a beneficial improvement design.

Description

The improved tongue-and-groove structure of consolidated floor

Technical field

The utility model relates to the tongue and groove structure of strengthening base plate, especially about a kind of improved tongue-and-groove structure.

Background technology

Consolidated floor is a kind of building material that developed recently gets up, for wooden floor, because of its have good and cheap, sturdy and durable, paving process is simple, operating expenses is low and dismountable characteristics, and receive publicity and show wide use prospect.Because consolidated floor is to rely on the set tongue and groove structure of its periphery to realize docking between plate and the plate, and be directly to be paved on ground and not establish the keel frame.So the shape of this plate tongue and groove section, structure have important action value to the butt joint on floor and the quality of mating formation.The tongue and groove on so-called floor is to be made of tenon and tongue-and-groove, and tenon must be corresponding identical with the section configuration of tongue-and-groove, that is to say that tenon can insert in the tongue-and-groove smoothly.Several tongue and groove structures of existing known use; As flat mouthful of tenon of card edge type, be characterized in that the tenon mouth structure is simple, but the joint on floor is thrown off easily or is cracked.Also have a kind of special-shaped tenon of being made up of curve, the lower camber side of its tenon is provided with projection and the groove that prevents that buttcover plate from throwing off.Yet, find in actual the use that when the floor was stressed, this joint still can produce the cracking that sink.

The utility model content

For overcoming the defective that above-mentioned existing consolidated floor tongue and groove structure exists, the purpose of this utility model is to propose the improved tongue-and-groove structure of a kind of consolidated floor.

For reaching this purpose, on the basis of existing consolidated floor tongue and groove structure, take following technical scheme: the improved tongue-and-groove structure of a kind of consolidated floor, comprise the set tenon shape tongue and groove that coincide each other of plate body and periphery thereof, it is characterized in that: the section of tenon be one by two arcs up and down and the figure formed of line segment always, contain sawtooth projection in the last camber line of its section; The section of tongue-and-groove is a groove that matches with tenon section figure, contain in the last camber line of its groove section with tenon on the sawtooth that coincide of sawtooth projection in the camber line recessed; It is recessed that the last cambered surface of tenon and tongue-and-groove is provided with a correspondence identical Saw blade and sawtooth at least, and it is recessed that the last cambered surface of tenon and tongue-and-groove is provided with three correspondences identical Saw blade and sawtooth.

Press the consolidated floor that such scheme is implemented, because cambered surface has designed Saw blade and sawtooth is recessed on tenon and tongue-and-groove, this Saw blade (recessed) has not only effectively stoped the disengagement on floor, and triple Saw blade (recessed) has significantly increased the tension dynamics of its combination.Confirm that through using the improvement of this tongue-and-groove structure also has the effect that can prevent the plate facial disfigurement.The utility model is real to be a kind of useful improvement design.

Advantage of the present utility model: tenon and tongue-and-groove partial design 3 heavy snap closes, increased tension intensity; Traditional approach latches in the bottom of plate face, and the design further improves the tension intensity of plate face on the top of plate face, and result of use is better, in case timber shrinks, only can produce distortion at the plate basifacial, can not exert an influence to the plate face; Improved the utilization rate of raw material effectively, because the size that only sell with the plate face on the floor is as the criterion, traditional snap close is owing to be tension down, so plate face loss 4-5mm, and the design is owing to be to go up tension, substantially lost area not.

Description of drawings

Fig. 1 is the section structure schematic diagram of a kind of embodiment of the utility model.

The specific embodiment

Be further described in detail for embodiment with regard to a kind of tenon shape tongue and groove in conjunction with the accompanying drawings with triple sawtooth.Two avris of plate body 1 are shaped on tenon 2 and tongue-and-groove 3 respectively, wherein, the figure that the section of tenon is made up of last arc 24 and following arc 21 and a straightway 22, be shaped on three sawtooth projections 23 in the last arc, the so-called camber line of going up is that camber line that this camber line points to floor facing plate (or referring to the facing plate the most approaching), and camber line upwarps slightly a little up and down.Another avris of the plate body 1 corresponding with tenon 2 is shaped on the groove 3 that the section figure with tenon 2 matches, and changes to be shaped on the sawtooth recessed 33 that three serrate projections 23 with tenon 2 match in the last arc of groove 3.If with the section of tenon 2 and tongue-and-groove 3 longitudinal extension along the floor, then the last cambered surface of tenon has promptly been made three vertical Saw blades 23, in like manner, the last cambered surface of tongue-and-groove then is shaped on the three vertical sawtooth recessed 33 that match with first three Saw blade.So, during construction, as long as the tenon on floor is penetrated in the tongue-and-groove on another floor that is adjacent (see the left side in the accompanying drawing illustrate).

Claims

1, the improved tongue-and-groove structure of a kind of consolidated floor, comprise the set tenon shape tongue and groove that coincide each other of plate body and periphery thereof, it is characterized in that: the section of tenon be one by two arcs up and down and the figure formed of line segment always, contain sawtooth projection in the last camber line of its section; The section of tongue-and-groove is a groove that matches with tenon section figure, contain in the last camber line of its groove section with tenon on the sawtooth that coincide of sawtooth projection in the camber line recessed.

2, by the improved tongue-and-groove structure of the described consolidated floor of claim 1, it is characterized in that: it is recessed that the last cambered surface of tenon and tongue-and-groove is provided with a correspondence identical Saw blade and sawtooth at least.

3, by the improved tongue-and-groove structure of the described consolidated floor of claim 1, it is characterized in that: it is recessed that the last cambered surface of tenon and tongue-and-groove is provided with three correspondences identical Saw blade and sawtooth.
