Problems solved by technology

Although the above-mentioned beams are also easy to use, they generally have the defects of high cost, large size and heavy weight.
Among them, although the cost of wooden beams is low, the steel is low, easily deformed, and easily damaged; the advantages of aluminum alloy beams are light weight and strong rigidity, but the cost is high; steel beams have high rigidity, but are too bulky and extremely inconvenient for construction and installation.

Embodiment Construction

[0016] Referring to Fig. 1 and Fig. 3, the steel-wood integrated I-beam according to the present invention includes a wooden beam 1, and in the longitudinal direction of the wooden beam, its wide two sides, that is, the two sides placed vertically when in use, are fixedly connected with a stressed section steel 2, The two ends of wooden beams are fixedly connected with end caps 3 with screws 4 . The connection between the wooden beam 1 and the stressed section steel 2 or the head 3 can be connected by screws or rivets.

[0017] Referring to Fig. 2 and Fig. 4, the cross-sectional shape of the stressed section steel 2 is a rectangular tubular shape, one wide surface has an opening running through the entire length, and on the other wide surface, a row of through holes or The upper and lower rows of through holes are used to install screws. The number of through holes is determined according to the length of the I-beam, and the distance between the holes is generally about 50cm. ...

Abstract

The invention discloses a steel-wood integration I-beam, which is composed of wooden beam, wherein the force type steel is connected to two lateral surfaces in the wooden beam length direction; two ends of wooden beam connects to roll end; the I-beam uses extrusion steel plate teeth and fastener to make the section steel and timber compact for one body; the steel-wood integration I-beam has stronger hardness, good versatility, which is fit for supporting of building form plate such as steel-wood mold plates, steel form, bamboo plywood and so on; the cost of the steel-wood integration I-beam is 50% aluminum alloy beam, 85% steel beam and 95% wood girder; The I-beam reduces the cost of transport and storage.

Description

technical field [0001] The invention relates to a building formwork support structure, in particular to a steel-wood integrated I-beam. Background technique [0002] In the construction of houses and roads and bridges, the supporting beams and secondary beams in the commonly used formwork support system include wooden beams, steel beams, aluminum alloy beams, and the like. Although the above-mentioned various beams are also easy to use, they generally have the defects of high cost, large volume and heavy weight. Among them, although the cost of wooden beams is low, the steel is low, easily deformed, and easily damaged; the advantages of aluminum alloy beams are light weight and strong rigidity, but the cost is high; steel beams have high rigidity, but are too bulky and extremely inconvenient for construction and installation. . Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects and provide a steel-wood integr...
