Abstract
The utility model discloses a combined box beam. The box beam is characterized in that a box steel frame formed by a top flange, a bottom flange and two web plates is included, wherein a first bambooor wood plate is fixedly arranged on the outer side of each web plate of the steel frame, a second bamboo or wood plate is fixedly arranged on the upper surface of the top flange of the steel frame, and a third bamboo or wood plate is fixedly arranged on the lower surface of the bottom flange of the steel frame. The box beam has the advantages that the traditional reinforced concrete box beam andclean steel box beam are replaced by the combination of the steel frame and the bamboo or wood plates, so as to reduce the dead weight of the traditional box beam and the cost, and to guarantee higherbearing capacity and rigidity of the box beam; and the bamboo or wood plates are all fixedly adhered to the steel frame through adhesive, thereby achieving convenient processing, simple manufacture,suitability for batch production of enterprises, as well as high on-site assembly speed and industrialization level.
Description
Technical field
The utility model relates to beam, the rod structure in a kind of civil engineering, especially relates to a kind of combined box-shaped beam.
Background technology
In field of civil engineering, frame construction is modal form of structure, and the section form that constitutes the beam and column of frame construction generally has rectangle, I-shaped, box-shaped etc.The beam of square-section is made simple, saves time conveniently, but high material consumption, from great; And the beam of non-solid section such as I-shaped, box-shaped can improve stock utilization, alleviates deadweight, is reasonable developing direction.But the making complexity of reinforced concrete box girder wherein, the dissemination in the medium and small project structure is also little, though and the box-girder that clean steel is made it is easy to make, steel using amount is bigger, cost is higher.The mechanical property of bamboo wood and timber itself is better, has higher intensity, be suitable as structural element, in order to alleviate the deadweight of conventional boxes ellbeam, simultaneously in order to reduce cost, available bamboo wood or timber are done box-girder, but at present the processing technology of the bamboo wood of box section or wood members that is that all right is ripe, processing is difficulty relatively.
Summary of the invention
Technical problem to be solved in the utility model provides the combined box-shaped beam that a kind of weight is lighter, easy to process and stress performance is good.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of combined box-shaped beam, it comprises by the upper and lower edge of a wing and two blocks of box-shaped steelframes that web constitutes, the outside of described steelframe web is set with first bamboo clappers or first plank, be set with second bamboo clappers or second plank on the upper surface of described steelframe top flange, be set with the 3rd bamboo clappers or the 3rd plank on the soffit of described steelframe bottom flange.
The width of described top flange is identical with the width of described bottom flange, and the overhanging width of described top flange equals the thickness of described first bamboo clappers or first plank.
The height of described first bamboo clappers or first plank is equal to or slightly less than the height of described web, the width of described second bamboo clappers or second plank equals or is slightly larger than the width of described top flange, and the width of described the 3rd bamboo clappers or the 3rd plank equals or be slightly larger than the width of described bottom flange.
The junction on the described steelframe web and the described upper and lower edge of a wing is provided with transition chamfering or transition arc, makes the intensity of box-girder better.
Described first bamboo clappers or first plank, described second bamboo clappers or second plank, described the 3rd bamboo clappers or the 3rd plank all are bonded on the described steelframe by adhesive.
Compared with prior art, the utility model has the advantages that because box-girder has substituted traditional reinforced concrete box girder and clean steel box-girder with the form that steelframe and bamboo clappers or plank make up, alleviated the deadweight of conventional boxes ellbeam, also reduced cost, box-girder higher capacity and rigidity have also been guaranteed simultaneously, and bamboo clappers or plank all are bonded on the steelframe by adhesive, easy to process, make simple, being suitable for enterprise produces in batches, and the on-site consolidation speed of application is fast, the industrialization degree height.
Description of drawings
Fig. 1 is the structural representation of the utility model cross section.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of combined box-shaped beam, it comprises by top flange 12, bottom flange 13 and two blocks of box-shaped steelframes that web 11 constitutes, the width of top flange 12 is identical with the width of bottom flange 13, steelframe web 11 and top flange 12, the junction of bottom flange 13 is provided with transition chamfering 14, the outside of steelframe web 11 is bonded with first bamboo clappers 2 by adhesive, the height of first bamboo clappers 2 equals the height of web 11, the overhanging width of top flange 12 equals the thickness of first bamboo clappers 2, be bonded with second bamboo clappers 3 by adhesive on the upper surface of steelframe top flange 12, the width of second bamboo clappers 3 equals the width of top flange 12, be bonded with the width that the 3rd bamboo clappers 4, the three bamboo clappers 4 width equal bottom flange 13 by adhesive on the soffit of steelframe bottom flange 13.
In the foregoing description, the material of bamboo clappers is an artificial bamboo board, bamboo clappers can also substitute with solid wood plate or artificial board, the web 11 and the top flange 12 of steelframe, the junction of bottom flange 13 can substitute transition chamfering 14 with transition arc, the height of first bamboo clappers 2 can be slightly less than the height of web 11, the width of second bamboo clappers 3 can be slightly larger than the width of top flange 12, the 3rd bamboo clappers 4 width can be slightly larger than the width of bottom flange 13, the box-shaped steelframe can be by hot rolling, clod wash, methods such as cold rolling and steel plate welding process, in addition, this combined box-shaped beam also can be done column after upright uses.
