Abstract

The utility model provides a light wall board with a tongue-and-groove structure. The structure is as follows: both sides along the long direction of the wall board are respectively provided with symmetrical tongue-and-grooves which are mutually communicated alpha and omega. The tongue-and-groove is provided with a reducing structure. In this way, after the wall boards are pairwise connected, the edge forms a closed mortise with a reducing at the middle. A connecting post formed after the cementation can tightly lock the wall boards of both sides to increase the stability of the connecting part. At the same time, if the connecting post retracts because of dryness, the dovetail type reducing can make the connecting post tightly press against the inner wall of the reducing of the wall board without generating any crack. The utility model is suitable to install the walls of various houses. The structure doesn't need to be specially designed in anticipation. The utility model doesn't need pre-embedding elements or the locking for a lath and is a novel wall means.

Description

The first kind: male and female tongue-and-groove joint form promptly vertically is respectively equipped with groove and raised line on the interface of both sides.During construction, pass through the splicing of this groove or raised line between the adjacent wallboard; Then, in butt joint, disclose a kind of tenon formula building partition plate that has groove and boss, splice in twos during construction and get final product as Chinese patent CN2108760.Because the joggle contact area is few, a little less than the caulking material thin thickness, can not can not form an integral wall with firmly boning well between plate and the plate.Therefore, when building structure generation STRESS VARIATION, the destructive power that their cohesive force produces when being less than STRESS VARIATION far away and cause longitudinal crack.

Second class: vertical both sides of wallboard all are grooves.After alignment by this groove between the adjacent wallboard or the splicing, grouting makes plate and plate, plate and main body etc. docks to lock to become possibility in the butt hole seam then, so the simultaneously complete body of wall of formation.The tenon structure of existing tenon formula wallboard all is open, and the front end of its tongue-and-groove is bigger, and the rear end is less.Like this behind the wallboard assembly unit mortise perfusion slurry, because the bond line material exists dry the contraction, after shrinking, material in the mortise can form the slit, and the wallboard that causes splicing mutually is loosening, this just must make the junction shrinkage cracking occur, not only influences the sound-insulating and heat-insulating effect in house, in case cracking just must influence the overall performance of view picture wall, also influence the attractive in appearance of metope, caused the body of wall instability.

Summary of the invention:

The purpose of this utility model provides a kind of Light trabs that has the tongue and groove tenon groove structure.

The technical solution of the utility model is: a kind of Light trabs that has the tongue and groove tenon groove structure, be that wallboard is respectively equipped with the symmetrical tongue-and-groove that head and the tail connect mutually in both sides along its length, this tongue-and-groove can be two or more, it is characterized in that described tongue-and-groove has throat structure.Like this, its edge, two wallboard butt joint backs forms a middle part and has reducing sealing mortise, constitute an inner hollow column that has reducing sealing mortise between the two plate seams, the joint pin that perfusion slurry back forms can tightly pin the both sides panel edges, has increased the stability of connecting portion.Locking back partition board firmly is bonded into an integral wall like this, thereby has improved the shear resistance of wallboard.If joint pin produces dry the contraction, also can make it tightly push down wallboard reducing inwall, thereby can not produce the crack simultaneously owing to the existence of reducing.

The Light trabs that has a tongue and groove tenon groove structure provided by the utility model is simple in structure, easy construction.Its new-type tenon groove structure makes the wallboard of butt joint have locking function, has improved the connective stability between the wallboard, can prevent that dry contraction the in joint from producing the crack simultaneously.This product is applicable to the wall construction installation in various houses, is a kind of novel wall body construction.Its advantage is:

1, prevented that effectively common fault easy to crack from appearring in wallboard.

2, structure such as wall column does not need particular design in advance, need not give the locking of embedded part and batten.This technology is not subjected to the architectural plane partition wall not know size impact, all can realize locking.Partition wall and whole building are become one.

3, need not to plaster after wallboard is installed and to reach the senior acceptance criteria of plastering.Adopt the job site of Light trabs not have rubbish substantially,,, can often keep the clean and tidy clean of job site, improve the civilized construction degree so also there is not the transportation problem of a large amount of rubbish because of this operation of not plastering.

4, indoor circuit can adopt open-wire line or concealed wire to lay.When adopting concealed wire to lay, vertical electric wire can prolong in the wallboard hole to be laid; Horizontal wire can be when wallboard be installed, by wear cable conduct in advance in wallboard.

5, from heavy and light, body of wall is thin, and user's house usable floor area has increased 3%～6%.

6, product good processability is carried out the site assembly construction, is easy to cut out, assembly unit, and pipeline is buried underground very convenient.Simple installation has reduced wet trade and construction rubbish, has not only improved speed of application, and has alleviated labour intensity, accelerates 6～7 times of speed of applications, reduces labour intensity.Random watt of the brickbat that is difficult to clear up also can be reduced in the building site, has reduced engineering cost.

7, applied widely, Light trabs is widely used in that framework, frame are cut, tubular construction is built, large bay is built and old housing reform is made and add non-bearing party wall, locellus wall, kitchen, lavatory walls such as layer, also can be used as the decoration partition wall, mobile house body of wall, and steel construction wall.
