Abstract
The utility model relates to a composite construction's floor fossil fragments, including outer keel and keelson, the keelson for the long banding lumps of wood, be equipped with the recess on relative two sides of keelson, the outer keel is the cross -section for the U -shaped is right angle bending's sleeve pipe, and the opening part of outer keel U -shaped is equipped with the flank of stretching in two, and the outer keel is on flank and recess cup joint the outer wall at the keelson, and the up end of keelson is higher than the up end of outer keel, and the front end of outer keel stretches out the preceding terminal surface of keelson, and the rear end face of outer keel is stretched out to the rear end of keelson, the utility model discloses use inside and outside fossil fragments to cup joint, not only connect convenient, solved traditional wooden fossil fragments intensity low, connect unstable defect, moreover the design that is higher than the outer keel of keelson up end make the lumps of wood and the contact of floor bottom, avoided steel sleeve pipe to the injury of floor bottom, prolonged the life on floor.
Description
Technical field
The utility model relates to a kind of keel, is specifically related to a kind of common joists of composite construction.
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 of composite construction, these keel solve the defect that conventional wooden keel intensity is low, connect instability, and can not produce damage to the floor of laying thereon, and then extend the application life on floor.
Following scheme is adopted in order to reach above-mentioned technical purpose the utility model:
A common joists for composite construction, comprises outer keel and keelson, and 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 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, and wherein the sleeve pipe of outer keel uses steel.
Further, the upper surface of keelson described in the utility model exceeds outer keel upper surface 1 ~ 2.5cm.
Further, the external part of outer keel described in the utility model is provided with multiple nailing hole.
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 the common joists of composite construction, outer keel is the sleeve structure of U-shaped, sleeve pipe uses steel, after the keelson made by the lumps of wood and outer keel are socketed, improve the ability of keel bearing load, outer keel arranges nailing hole, interior outer keel can be fixed together firmly by nailing, make inside and outside keel not easily produce relative movement, make the common joists of composite construction have good stability.2. the utility model arranges groove on the side of keelson, during inside and outside keel socket, the upper surface of keelson is higher than the upper surface of outer keel, because the upper surface of keel can with the floor contact laid thereon, this design makes the lumps of wood and floor lower layer contacts, the sleeve pipe avoiding steel, to the injury of floor bottom, extends the application life on floor.3. 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, and when two Keel butt joints, keelson socket enters in adjacent outer keel, add on outer keel and be provided with nailing hole, therefore two keel firmly can be docking together by nailing.
Accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of common joists of composite construction, 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 U-shaped opening part of outer keel 1 is provided with the flank 4 stretched in two, outer keel is socketed on the outer wall of keelson through flank 4 and groove 3, on the sidewall of outer keel 1, array distribution has multiple nailing hole 5, the upper surface of keelson 2 exceeds the upper surface 1.5cm of outer keel 1, the front end face of keelson 2 is stretched out in the front end of outer keel 1, the external part of outer keel is provided with multiple nailing hole 5, the rear end face of outer keel 1 is stretched out in the rear end of keelson 2, and wherein the sleeve pipe of outer keel 1 uses steel.
When the common joists of composite construction of the present utility model needs to dock, keelson socket enters in adjacent outer keel, then uses nailing, by the nailing hole on outer keel, keelson and adjacent outer keel is firmly docking together.The utility model uses inside and outside keel to be socketed, not only easy to connect, solve conventional wooden keel intensity low, connect unstable defect, and keelson upper surface makes the lumps of wood and floor lower layer contacts higher than the design of outer keel, the sleeve pipe avoiding steel, to the injury of floor bottom, extends the application life on floor.
