Description
Technical field
The utility model relates to a kind of keel, is specifically related to a kind of common joists with main muscle.
Background technology
In building decoration engineering, be used for bearing the stress frame of decorated wall surface, cylinder, bottom surface, door and window and ceiling finish material quality, be called decoration framework, also can be called keel, the Main Function of keel be fix, make, load-bearing.The kind of keel has a lot, according to the difference making material, can be divided into rough ground, lightgage steel joist, aluminium alloy joist, steel joist etc.; Divide according to use position, channel, straight wall keel, floor file keel can be divided into again and hang keel.
Wherein, rough ground is widely used in the fields such as ceiling, partition wall, wood flooring, barrier, and multiselect material is more loose, and unsightly, and water content is few, little, not easy to crack, the on-deformable seeds of drying shrinkage for texture, as: Chinese fir, masson pine, lime tree, Korean pine etc.It is light that these rough grounds have quality, easily processing, the advantage such as native texture is attractive in appearance, mechanical property is good, but while also there is the shortcomings such as moisture expansion and drying shrinkage, yielding, corrosion-resistant.
In modern house finishing, wood flooring is the one finishing mode grown most, and this finishing mode is owing to bringing great comfort and beautiful enjoyment to indoor, thus very popular.On the market for installing keel that wood flooring uses generally, directly solid wood is laid on concrete floor, then laying floor on solid wood keel.Although this method is simple and convenient, on the one hand, the ability of wooden keel bearing load is lower, the application life of keel is short, the number of turnover is few, meanwhile, due to the reason of material and connected mode, easily produce after rough ground connects and rock, do not possess good stability; Wood materials is expanding with heat and contract with cold or can deform in situation of making moist on the other hand, and then makes the floor deformation being laid on its top layer, reduces the application life on floor.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of common joists with main muscle, these keel solve the defect that conventional wooden keel intensity is low, connect instability, can assist the seamless link between floor, and the right angle realized in keel connection connects and straight line connects.
Following scheme is adopted in order to reach above-mentioned technical purpose the utility model:
With a common joists for main muscle, comprise outer keel and keelson, described keelson is the lumps of wood of strip, and two sides that keelson is relative are provided with groove, outer keel is cross section is the sleeve pipe that U-shaped at right angles bends, the opening part of outer keel U-shaped is provided with the flank stretched in two, outer keel is socketed on the outer wall of keelson through flank and groove, the upper surface of keelson is higher than the upper surface of outer keel, the upper surface of keelson is provided with at least one main muscle, the front end face of keelson is stretched out in the front end of outer keel, the rear end face of outer keel is stretched out in the rear end of keelson, a side is had at least to be flexible connection face in four sides of outer keel external part, flexible connection face through hinge and outer keel hinged, flexible connection face is provided with nailing hole, other side of outer keel external part is also provided with nailing hole.
Further, the cross section of main muscle described in the utility model is any one in triangle, trapezoidal, rectangle, semicircle.
Further, hinge folding angle described in the utility model is 90 degree.
Further, on the sidewall of outer keel described in the utility model, array distribution has multiple nailing hole.
The beneficial effects of the utility model are: 1. the utility model provides a kind of these keel of the common joists with main muscle is composite construction, be socketed to form by inside and outside keel, wherein outer keel is steel, keelson is wooden, after both sockets, improve the ability of keel bearing load, make the common joists of composite construction have good stability.2. the upper surface of the keelson of the utility model keelson is higher than the upper surface of outer keel, and on the upper surface of keelson, be also provided with at least one main muscle, because the upper surface of keel can with the floor contact laid thereon, this design first makes the lumps of wood and floor lower layer contacts, avoids the sleeve pipe of steel to the injury of floor bottom; The second, when the present invention and supporting floor use, the groove on main muscle and floor cooperatively interacts, and can assist the seamless link between floor, substantially increase installation quality.3. the utility model is provided with at least one flexible connection face on outer keel external part, when there being corner keel to need switching, the flexible connection face of opening, stably be fixedly connected with the keel of corner Vertical dimension flexibly, when not needing right angle to transfer, the utility model also can connect keel on the same line.

Fig. 1 is general structure schematic diagram of the present utility model.
Fig. 2 is flexible connection face that the utility model is adjacent view when opening.
Fig. 3 be the utility model and right angle to the connection status schematic diagram of keel.
Fig. 4 be the utility model and floor be assembled figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, Figure 2 and Figure 3, a kind of common joists with main muscle, comprises outer keel 1 and keelson 2, and described keelson 2 is the lumps of wood of strip, and two sides that keelson 2 is relative are provided with groove 3, outer keel 1 is cross section is the sleeve pipe that U-shaped at right angles bends, the opening part of outer keel 1U shape is provided with the flank 4 stretched in two, outer keel is socketed on the outer wall of keelson 2 through flank 4 and groove 3, on the sidewall of outer keel, array distribution has multiple nailing hole, nailing 9 is provided with in nailing hole, in auxiliary, stable bond between outer keel, the upper surface of keelson 2 is higher than the upper surface of outer keel 1, the upper surface of keelson 2 is provided with at least one main muscle 5, the front end face of keelson 2 is stretched out in the front end of outer keel 1, the rear end face of outer keel 1 is stretched out in the rear end of keelson 2, a side is had at least to be flexible connection face 6 in four sides of outer keel 1 external part, flexible connection face 6 is hinged through hinge 7 and outer keel, hinge folding angle is 90 degree, flexible connection face is provided with nailing hole 8, other side of outer keel external part is also provided with nailing hole 8.As shown in Figure 1, in the present embodiment, the cross section of main muscle is rectangle, and in actual use, the cross section of main muscle can select any one in triangle, trapezoidal, rectangle, semicircle.
As shown in Figure 3, when the keel of right angle orientation need to transfer, open joint face, the flexible connection face of opening can be fixedly connected with through nailing with keel to be transferred flexibly, the front end face of outer keel of the present utility model stretches out the front end face of keelson, when not needing right angle to transfer, the straight line that the utility model also can meet between adjacent keel connects.As shown in Figure 4, be the utility model and supporting floor bonding state when assembling, as can be seen here, main muscle the seamless link can assisted between floor is set, substantially increase installation quality and connect.Finally, the utility model uses inside and outside keel to be socketed, and the square tube of outer keel uses steel, and intensity is high, enabling capabilities good; Keelson uses wooden, not only easy to connect after both sockets, and solves the defect that conventional wooden keel intensity is low, connect instability, makes mounting structure more stable.
