Abstract
The utility model belongs to building support materials and particularly relates to a steel and wood combined composite sleeper. The steel and wood combined composite sleeper comprises a sleeper body and two symmetric steel jackets, and is characterized in that two pairs of grooves are symmetrically arranged on two sides of the sleeper body respectively, the two symmetric steel jackets wrap the sleeper body and are respectively nested in the two pairs of grooves to form two pairs of reinforcing ribs. The steel and wood combined composite sleeper has the advantages that since two reinforcing ribs are additionally arranged in original steel sleeper, the steel and wood combined composite sleeper is high in bending resistance and higher in strength. Furthermore, wood portions of the upper and lower sides of the steel and wood combined composite sleeper are exposed, a metal backing plate on the upper side is not easy to slip and high in safety. The wood portions in the middle of the steel jackets is composed of all wood and are higher in strength than original finger joint wood and woodworking plates.
Description
Technical field:
The utility model belongs to the building-supporting material, is exactly a kind of composite sleeper of steel and wood composite specifically.
Background technology:
Sleeper is generally used for carrying object, is railway construction, the laying of dedicated track equipment, the support of construction work, the indispensable material in load bearing equipment field.According to the difference of its material, sleeper mainly is divided into wooden sleeper, steel sleeper.Common wooden backing material wherein, due to the timber self-characteristic, flexural strength is not enough, is easily exposed to the weather and the impact of sleety weather etc., and its service life is shorter, so need periodic replacement, need to expend a large amount of timber.And sleeper before use generally must be anticorrosion through oiling, and in the anticorrosion process of above-mentioned oiling, the use of inorganic agent easily causes environment pollution.
Steel sleeper in addition, single face steel sleeper namely, three faces are steel, only reveal a timber part, middle wooden part is generally finger joint wood and woodwork plate, self intensity a little less than, three is the steel parcels, below metal when partly padding on another metal, owing to being all metal material, easily landing, insecure, cause potential safety hazard.And only have one side that reinforcing rib is arranged, intensity is still not high.
Summary of the invention:
The utility model is for the problems referred to above, a kind of composite sleeper of steel and wood composite is provided, the technical scheme of taking is: a kind of steel wood composite sleeper, comprise the sleeper body, and steel bushing, it is characterized in that: be respectively arranged with two pairs of grooves in the symmetrical both sides of sleeper, two symmetrical steel bushings coat sleeper, be nested in respectively this in groove, consist of two pairs of reinforcing ribs.
Timber in the middle of described steel bushing is whole wood.
The groove of the symmetrical both sides of described sleeper, wherein the spacing of the groove of a side is greater than the spacing of opposite side groove.
The cross section of described sleeper is the H structure.
The cross section of described sleeper is trapezoidal.
The utility model has the advantage of: owing to having increased by two reinforcing ribs than original steel sleeper, so bending resistance is strong, intensity is larger.In addition, upper and lower faces all exposes wooden part, above during the bearing metal backing plate, be difficult for landing, degree of safety is high.Timber in the middle of steel bushing is partly for to be made of whole wood, and is larger compared with original finger joint wood, woodwork plate intensity.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of composite sleeper of steel and wood composite comprises the sleeper that a whole wood consists of, and is respectively arranged with two pairs of grooves in the symmetrical both sides of sleeper, timber 2 two sides are respectively steel bushing 1 parcel of absolute construction, two steel bushing bilateral symmetry are embedded in respectively in these two pairs of grooves, consist of two pairs of reinforcing ribs 3.
Owing to having increased by two reinforcing ribs than original steel sleeper, make the bending resistance of product stronger.In addition, with the difference that the spacing of two pairs of grooves arranges, be also in order to increase the intensity of steel sleeper.
The cross section of the sleeper that provides in this embodiment, is the H structure.But, being not limited to this structure, its cross section can be also trapezium structure.Perhaps according to actual needs, do simple distortion, still belong to protection domain of the present utility model.
Claims (5)
1. the composite sleeper of a steel and wood composite, comprise the sleeper body, and steel bushing, it is characterized in that: be respectively arranged with two pairs of grooves in the symmetrical both sides of sleeper, two symmetrical steel bushings coat sleeper, are nested in respectively this in groove, consist of two pairs of reinforcing ribs.
2. the composite sleeper of described a kind of steel and wood composite according to claim 1 is characterized in that: the timber in the middle of described steel bushing is whole wood.
3. the composite sleeper of described a kind of steel and wood composite according to claim 1 is characterized in that: the groove of described sleeper symmetrical both sides, wherein the spacing of the groove of a side is greater than the spacing of opposite side groove.
4. the composite sleeper of described a kind of steel and wood composite according to claim 3, it is characterized in that: the cross section of described sleeper is the H structure.
5. the composite sleeper of described a kind of steel and wood composite according to claim 3, it is characterized in that: the cross section of described sleeper is trapezoidal.
