Further, the aperture length that described first channel-section steel and second channel-section steel are set is φ, wherein, and 0＜φ≤100mm; The hole heart is set apart from being d, wherein, 0＜d≤1000mm.
Further, the aperture length φ of first channel-section steel and second channel-section steel is 15mm, and the hole heart is 30mm apart from d.
Further, the described material of following closely is wood materials or plastics.
Further, the bottom of described composite supporting beam is provided with a plurality of connectors.
Further, described first channel-section steel and second channel-section steel all with can follow closely material and removably connect.
Further, the height of the material followed closely of described filling is equal to or higher than the height of described second channel-section steel.
Further, described first channel-section steel and second channel-section steel by alloy steel, aluminium just or plastic-steel form.
(3) beneficial effect
Technique scheme has following beneficial effect: composite supporting beam provided by the invention, not only have favorable rigidity but also have nailability, and sturdy and durable, and farthest reduce construction costs.When supporting composite stringers, can serve as cross binding, expanded its application category.And the adjustable length of this composite supporting beam has effectively satisfied the floor demand of different size, conveniently carries and deposits, and raises labour efficiency.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
Shown in Fig. 1-4, embodiment of the invention composite supporting girder construction comprises: the groove footpath of first channel-section steel 1 and second channel-section steel, 2, the second channel-section steels 2 is greater than the groove footpath of first channel-section steel 1.Wherein, the length of setting first channel-section steel 1 is L1, and the length of second channel-section steel 2 is L2.One end of first channel-section steel 1 is positioned at second channel-section steel 2, and second channel-section steel 2 overlaps with first channel-section steel 1 and be connected, and the length of its overlapping region is set to D, then the length L of this composite supporting beam
x=L1+L2-D.This first channel-section steel 1 and second channel-section steel 2 by alloy steel, aluminium just or plastic-steel form, have favorable rigidity, play load-bearing supporting role preferably.
With perforate on the central axis of first channel-section steel 1 and second channel-section steel, 2 bottoms, its aperture is that (0＜φ≤100mm), the hole heart is apart from being d (0＜d≤1000mm) for φ.The length of composite supporting beam be can set according to the actual requirements, and then aperture and hole heart distance on first channel-section steel 1 and second channel-section steel 2 further limited.More preferably, the aperture that the hole is set is 15mm, and its hole heart distance is 30mm.Adopt screw that the hole of first channel-section steel 1 and second channel-section steel, 2 diverse locations is coupled together, can adjust the size of first channel-section steel 1 and second channel-section steel, 2 overlapping region d.Can follow closely material with filling in the groove of first channel-section steel 1 and second channel-section steel 2, be specially first channel-section steel 1 and fixedly connected with the bottom that can follow closely material by screw 4, second channel-section steel 2 is fixedlyed connected with the bottom that can follow closely material by screw 4.Wherein can follow closely the material that material can penetrate with screw for wood materials, plastic material or other.The height of the material followed closely of filling is not less than the height of second channel-section steel 2.The wood materials or the plastics of filling in first channel-section steel 1 and second channel-section steel, 2 grooves make the composite supporting beam have good nailability.
Be connected in order to make that composite supporting beam and support member are convenient, in the bottom of composite supporting beam a plurality of connectors 5 are set,, make mountain dance beam can support composite stringers when vertical by this connector 5, laterally can play the effect of support, further expand the range of application of mountain dance beam.
In the practical application, the distance between two beams of floor commonly used is generally 1.2-9.0m, and between 3.0-5.0m, therefore, the length range that the composite supporting beam is set is between the 3.0-5.0m to the length of separate room floor usually, and the standard width of a room in an old-style house that can satisfy building changes.In the specific implementation, the length that first channel-section steel 1 is set is 2.4m, and the length of second channel-section steel 2 is 3m, by connecting the diverse location in hole on first channel-section steel 1 and second channel-section steel 2, make win channel-section steel 1 and second channel-section steel, 2 inside and outside cross-lappings, make that the length of mountain dance beam is adjustable between 3.0-5.0m.
Composite supporting beam provided by the invention not only has favorable rigidity but also have nailability, and is sturdy and durable, and farthest reduces construction costs.When supporting composite stringers, can serve as cross binding, expanded its application category.And the adjustable length of beam is waved on this mountain, has effectively satisfied the floor demand of different size, conveniently carries and deposits, and raises labour efficiency.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
