Abstract

The present invention relates to a steel and wood integrated H-shaped beam, which comprises a wooden beam, in the length direction of the wooden beam, both sides of the width are fixedly connected with stressed profile steel, two ends of the wooden beam are fixedly connected with a head. The H-shaped beam adpresses and connects profile steel and timber together by adopting punching steel plate teeth and fastening pieces, the steel and wood integrated H-shaped beam has stronger rigidity, good universality, good sturdiness and durability, which is suitable for supporting all building templates, such as steel and wood templates, steel templates, bamboo and adhesive templates, mecarta templates, wood templates, etc. The cost of the steel and wood integrated H-shaped beam is only 50% of that of aluminium alloy beam, 85% of that of steel beam and 95% of that of timber girder. The H-shaped beam has small volume, which can decrease the cost of transportation and storage, and no waste materials can be generated in a construction, so the cost of clearing waste materials can be decreased.

Description

Steel and wood integrated I-shaped beam
Technical field
The present invention relates to the construction formwork supporting structure, specifically, relate to a kind of steel and wood integrated I-shaped beam.
Background technology
In building and road and bridge construction, generally support crossbeam in the form bracing system of Shi Yonging and secondary beam have wooden frame, girder steel, aluminum alloy beams or the like.Though above-mentioned various beam is also handy, ubiquity cost height, volume reach heavy defective greatly.Wherein, though the wooden frame cost is lower, stiffness is low, yielding, fragile; The advantage of aluminum alloy beams is in light weight, and rigidity is strong, but the cost height; Steel beam rigidity is big, but too heavy, and construction and installation are extremely inconvenient.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of sturdy and durable, economy is general, safety factor is high steel and wood integrated I-shaped beam is provided.
Steel and wood integrated I-shaped beam of the present invention, comprise wooden frame, length direction at wooden frame, two opposite flanks of wooden frame stressed shaped steel that has been fixedly connected, the two ends of the wooden frame end socket that has been fixedly connected, the cross section of described stressed shaped steel is a rectangular tubular, on the surface at the place, long limit of rectangular tubular, has the opening that runs through whole stressed shaped steel length, evenly be furnished with an exhausting hole or upper and lower two exhausting holes with the length direction on another surperficial relative surface, place, long limit, connect with wooden frame by the stressed shaped steel in these holes with opening.
Described stressed shaped steel has on the external surface of through hole and has the two rows tooth, and the layout of same toothrow is that each tooth point has a monodentate, perhaps arranges 3 monodentates triangularly, the setting of staggering mutually of upper and lower two rows' tooth points.
The shape of cross section of described end socket is a  shape, has the through hole of mounting screw on the both wings.
Described wooden frame is through preservative treatment.
Steel and wood integrated I-shaped beam of the present invention, adopt special structure, with punching press steel plate tooth and securing member shaped steel and timber are pressed and to be connected into one, make the rigidity of steel and wood integrated I-shaped beam stronger, the support that versatility is good, sturdy and durable, adapt to all construction formworks is as the support of Steel-wood forming board, steel form, bamboo glue pattern plate, bakelite template, wooden form etc.Use the cost of steel and wood integrated I-shaped beam to have only 50% of aluminum alloy beams, 85% of girder steel, 90% of wooden H-beam.This i beam volume is little, can reduce transportation and warehousing costs, and can not produce waste material in construction, therefore, can reduce the expense of clear away waste.

Fig. 1 is the structural representation of steel and wood integrated I-shaped beam of the present invention;
Fig. 2 is the via arrangements figure of the stressed shaped steel of i beam shown in Figure 1;
Fig. 3 is the schematic diagram of another embodiment of i beam of the present invention;
Fig. 4 is the A-A sectional view of Fig. 3;
Fig. 5 is a kind of layout of tooth of the stressed shaped steel of i beam shown in Figure 3;
Fig. 6 is the another kind of layout of tooth of the stressed shaped steel of i beam shown in Figure 3;
Fig. 7 is the structure chart of i beam end socket shown in Figure 1.
The specific embodiment
Referring to Fig. 1 and Fig. 3, steel and wood integrated I-shaped beam of the present invention comprises wooden frame 1, the wooden frame length direction, and the two sides that it is wide, the stressed shaped steel 2 even the time spent two sides of vertically placing have been fixedly connected, the two ends of wooden frame are with screw 4 end socket 3 that has been fixedly connected.Wooden frame 1 can connect with screw or rivet with connecting of stressed shaped steel 2 or end socket 3.
Referring to Fig. 2 and Fig. 4, the shape of cross section of described stressed shaped steel 2 is a rectangular tubular, has the opening that runs through whole length on wide of the one, on another wide, its length direction evenly is furnished with an exhausting hole or upper and lower two exhausting holes, so that mounting screw, the quantity of through hole are determined according to the length of i beam, the general about 50cm of pitch-row.
Referring to Fig. 5 and Fig. 6, has plurality of teeth on the described stressed shaped steel 2.Tooth has two rows at the width of steel plate, and this tooth is to take the punching press steel plate to form.In the layout of same toothrow, be that each tooth point has a monodentate, perhaps triangular ground is arranged 3 monodentates, the about 500mm-80mm of distance between each tooth.Upper and lower two rows' the tooth points setting of staggering mutually.
Referring to Fig. 7, described end socket 3 is installed in the two ends of wooden frame, and its shape of cross section is , has through hole on the both wings.During installation, both wings are positioned at the outside of steel plate 2, are fixed on the wooden frame with screw or rivet.
For increasing application life, described wooden frame 1 is through preservative treatment.
