Abstract

The utility model relates to a novel I-shaped bamboo-wood beam adopted by the supporting components of concrete forms and wood-structure houses. The I-shaped bamboo-wood beam is formed by joggling, nailing and gluing an upper frange plate, a lower frange plate and a web plate. The I-shaped bamboo-wood beam is characterized in that multiple-twin reinforcing bamboo-wood laths are symmetrically added onto the two sides of the web plate at intervals regularly, the positioning and the fixation among the laths and the upper and the lower frange plates are performed through joggling and nailing, and a cementing compound is adopted for gluing and fixation between the upper and the lower frange plates and between the web plate and the laths; and the cross sections of the two ends are rectangular. The upper and the lower frange plates are made through processing bamboo-wood laminated veneer lumber, reconstituted materials, integrated materials or solid wood santalum album strips; the web plate is made through processing a bamboo-wood glued board, laminated veneer lumber or an oriented-structure particle board; each bamboo-wood lath is made through processing the waste small materials produced in bamboo-wood processing; and the utility model has the advantages that the structure is reasonable, the processing is simple, the production can be specialized and standardized, and meanwhile, the bamboo-wood beam can be mounted and connected to be a beam with large span conveniently and is an resource-conserving structural material.

Description

A kind of novel wooden bamboo matter i beam

Technical field

The utility model belongs to the building unit technical field, particularly relates to a kind of novel wooden bamboo matter i beam that concrete blinding supporting member and wooden frame structure use.

Background technology

Wood bamboo matter i beam designs according to mechanical property requirements, accomplish the i-shape component that materials are economized, quality is little, intensity is big, can be used as the substitute products of traditional timber, its function admirable, wide, the easy construction of application, the solid wood beam, floor, the room support bar that not only can be used as wooden frame structure, support crossbeam and secondary beam in the engineering constructions such as also available building, road and bridge, tunnel in the form bracing system.Adopt at present metal connecting piece (bolt, wood screw, iron nail etc.), tongue-and-groove (rectangle, trapezoidal etc.) gummed connected mode to constitute one between the web of wooden bamboo matter material i beam commonly used and the wing plate, as the high-strength built H beam of patent CN2801933Y, CN200992773Y type of wood and bamboo i beam, the compound i beam of CN2876221Y bamboo wood, all adopt trapezoidal tongue-and-groove gummed connected mode, dovetail groove requirement on machining accuracy height, particularly swallow-tail form head, swallow tail shaped slot processing, assembling are not easy to mechanized, the effort of taking a lot of work, efficient is low; And on web, be bumped into spline when processing V-arrangement wedge groove, assembling, and easily cause web sandwich layer cracking and edge to burst apart, reduced the bond strength between web and the wing plate, influenced the physical and mechanical property of product.

Summary of the invention

The purpose of this utility model provides a kind of handling ease, rational in infrastructure, dimensionally stable, can realize the novel wooden bamboo matter i beam of suitability for industrialized production, the similar solid wood plate of two termination cross sectional shape square bar, install and fix when not only being convenient to construct, and be convenient to short beam be connected into long-span beams by metal connecting piece.

Technical solution of the present utility model is: a kind of novel wooden bamboo matter i beam is formed by joggle or nail joint and gummed by frange plate up and down, web; Its web bilateral symmetry is regular, the compartment of terrain increases manyly to strengthening wooden bamboo lath, positions fixingly between wooden bamboo lath and the frange plate by joggle or nail joint, and also sticks with glue the agent gummed between frange plate, web and the wooden bamboo lath and fixes; Two termination cross sectional shapes are rectangular.

Above-mentioned novel wooden bamboo matter i beam, frange plate is provided with corresponding tongue-and-groove and tenon with wooden bamboo lath two ends about it, and it is square, circular and oval that its shape has, and tenon size shape and tongue-and-groove are complementary;

Above-mentioned novel wooden bamboo matter i beam, it up and down also can adopt round tenon, nail or wood screw to be connected between frange plate and the wooden bamboo lath.

On structure, the utility model be about, the bilateral symmetry structure, stressed evenly, rational in infrastructure.Its unique distinction is that frange plate does not combine by tongue-and-groove with web up and down, but in the web both sides, regular interval ground increases several to wooden bamboo lath between the frange plate up and down, the equal coated with adhesive in all junctions, by joggle (or nail joint) and bonding adhesive glued joint with web and up and down frange plate be fixed into one tightly.

The novel wooden bamboo matter i beam that adopts the art of this patent to produce, its important advantage is: manufacture craft is simple, and each parts can be realized specialization, standardized production, the work efficiency height, cost is low; The wood bamboo lath can make full use of the little material of wooden bamboo processing residue and carry out processing and fabricating, has improved wooden bamboo processing and utilization rate; It is fixing to adopt wooden bamboo lath that web is positioned, and web need not the mortise head, and thin web advantage is more outstanding for using, and material is more saved; Two similar solid wood plates of termination cross sectional shape of product square bar is convenient to install and fix and connect into long-span beams, and characteristics such as have light weight, the ratio of strength to weight is big, intensity is high, dimensional stability is good, purposes is wide are a kind of structural timbers of resource-conserving.

Below in conjunction with accompanying drawing the utility model is further specified.

The specific embodiment

Embodiment 1:

Shown in accompanying

drawing

1,2, the utility model comprises up and down frange plate 1, web 2 and is vertically connected at the wooden bamboo lath 3 between the frange plate 1 up and down; Frange plate 1 is formed by wooden bamboo matter laminated veneer lumber, reorganization material, integrated timber or solid wood a tree, used in making timber for boats bar processing and fabricating up and down; Web 2 is formed by wooden bamboo plywood, laminated veneer lumber or oriented structure chipboard processing and fabricating; Wood bamboo lath 3 is formed by little material processing and fabricatings of processing residue such as wooden bamboo matter laminated veneer lumber, reorganization material, integrated timber, oriented structure chipboard or solid wood a tree, used in making timber for boats bars; In web 2 both sides, up and down increase between the frange plate more than 1 to wooden bamboo lath 3, the equal coated with adhesive of its contact surface, frange plate and wooden bamboo lath position fixing by tenon 6, tongue-and-groove 7 and bonding adhesive, also bonding between frange plate, web and the wooden bamboo lath by bonding adhesive, each parts is fixed into one tightly, makes novel wooden bamboo matter i beam.
