Description

Special-shaped steel-wood composite beam

Technical Field

The utility model relates to a steel wood composite beam technical field, more specifically relates to a heterotypic steel wood composite beam.

Background

In the horizontal structure construction of house buildings, high-rise buildings and super high-rise building projects in China, steel pipe fastener scaffolds, bowl fastener scaffolds, door scaffolds and the like are usually adopted as formwork support frames, and the battens with the thickness of 100mm multiplied by 100mm are usually taken as main beams, and the battens with the thickness of 50mm multiplied by 100mm are taken as secondary beams. The formwork of the vertical structure adopts bamboo-wood plywood as the formwork, 50mm multiplied by 100mm battens as secondary beams and steel pipes or section steel as back ridges besides a large formwork, a creeping formwork and a slip formwork. Therefore, battens are mostly adopted as secondary beams no matter in a horizontal structure or a vertical structure, but the 50mm multiplied by 100mm battens are few in turnover use times and large in wood consumption, so that a large amount of forest resources are wasted, the environmental pollution is serious, and the national policy of 'green construction' is not met.

At present, some construction units in China adopt woodwork beams, rectangular steel-wood secondary beams and n-shaped steel-wood secondary beams, the turnover use times are improved to a certain extent, wood is saved, and the problems are still solved, the bearing capacity is small, and the weight is large. Chinese patent publication No. CN206368488U, publication date 2016, 12 months, 27 days, discloses a steel-wood composite beam, which is composed of an upper flange plank, a lower flange plank, a light i-beam, and shear screws, wherein screw holes are left in the upper and lower flanges of the i-beam, the upper and lower flange planks are connected with the upper and lower flanges of the i-beam through the shear screws, bolt holes are left in both ends of the steel-wood composite beam for connecting with other building components such as columns, and the bearing capacity of the beam needs to be strengthened and needs more wood.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the shortcoming that current steel-wood composite beam bearing capacity is little, and the timber quantity is big, provide a heterotypic steel-wood composite beam. The utility model discloses can be general in horizontal construction and vertical structure template engineering, appearance rule straight, light in weight, bearing capacity are strong, the turnover use number of times is many, and the timber quantity is few, and economic cost is low.

In order to solve the technical problem, the utility model discloses a technical scheme is: the special-shaped steel-wood composite beam comprises a bent steel plate and battens, wherein the bent steel plate forms a cavity with a rectangular cross section, an opening is formed in one side of the cavity, the battens are embedded into the cavity through the opening, and the middle parts of the rest three sides of the cavity are inwards sunken to be tightly attached to the battens. In this technical scheme, the flitch is followed the opening embedding cavity, because the flitch is hugged closely to the trilateral centre of cavity is inwards sunken for combination beam overall structure is simple compact, and the bearing capacity that the structure that cavity and flitch formed is than current I-beam and several word roof beams is stronger, and stability is better.

Further, the edge of the opening is bent towards the cavity. The reaction force generated by the inwardly bent edges can clamp the embedded battens.

Furthermore, the four corners of the cavity and the batten form a first cavity, a second cavity, a third cavity and a fourth cavity. The formation of four cavities can strengthen the bearing capacity of the steel-wood composite beam.

Furthermore, the batten and the bent steel plate are fixedly connected through a plurality of bolts. The bolt penetrates through the bent steel plate and the batten.

Further, the cross-sectional dimension of the cavity is 70mm x 55 mm.

Further, the cross-sectional dimension of the flitch is 60mm x 25 mm.

Further, the length of the wood beam and the cavity is one of 300mm, 600mm, 900mm, 1200mm, 1500mm and 1800 mm. The length specification of the composite beam takes 300mm as a modulus, and is complete in matching from 300mm to 1800 mm.

Furthermore, the batten is a plywood batten. The plywood flitch can improve the utilization rate of wood and save wood.

Furthermore, a plurality of connecting holes are formed in the bent steel plate, and through holes corresponding to the connecting holes are formed in the battens. In the technical scheme, the connecting holes and the through holes are matched to penetrate through the whole steel-wood composite beam and are used for being connected with other building components.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model provides a cavity structures compares traditional I-shaped structure and can improve cavity bearing capacity, and the appearance is just straight, light in weight, can have enough to meet the need the use many times.

2. The utility model discloses in only adopted a plywood flitch, the timber quantity is few, and economic cost is low, can be general in horizontal structure and vertical structure template engineering.
