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

[0017] See figure 1 3, the steel-wood integrated I-beam of the present invention includes a wooden beam 1, the length of the wooden beam, its two wide sides, that is, the two sides that are placed vertically when in use are fixedly connected with the stressed steel 2, and the wooden beam A head 3 is fixedly connected with screws 4 at both ends. The connection between the wooden beam 1 and the stressed steel 2 or the head 3 can be connected by screws or rivets.

[0018] See Figure 2 and Figure 4 , The cross-sectional shape of the stressed steel 2 is a rectangular tube, one wide side has an opening that traverses the entire length, and on the other wide side, a row of through holes or two rows of upper and lower holes are evenly arranged in the length direction. Through holes to install screws. The number of through holes is determined by the length of the I-beam. Generally, the hole distance is about 50cm.

[0019] Referring to Figures 5 and 6, the stressed section steel 2 has a ...

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 so on. Although the above-mentioned beams are also easy to use, they generally have the disadvantages of high cost, large volume and bulkiness. Among them, although the cost of wooden beam is low, it has low rigidity, easy to deform and easy to damage; aluminum alloy beam has the advantages of light weight, strong rigidity, but high cost; steel beam has high rigidity, but is too bulky, and it is extremely inconvenient for construction and installation. . Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a steel-wood integrated I-beam that is dura...
