Abstract
The utility model discloses a flanged beam pertaining to the wood and bamboo category. The flanged beam comprises a ventral plate and an alar plate that is vertically connected with the upper part and lower part of the ventral plate. The ventral plate and the alar plates are solid or artificial board material pertaining to the wood and bamboo category, while the upper alar plate and the lower alar plate are both provided with a dovetail groove whose inner part is broader than the outer part in length direction; the ventral plate is a rectangle, whose thickness is matched with the width of the notches of the dovetail grooves; the upper end face and the lower end face respectively provided with a V-shaped wedge groove channel, while the upper end and the lower end of the ventral plate are respectively enchased into the dovetail grooves of the upper and alar plate and the lower alar plate. The V-shaped wedge groove channels at the upper end face and the lower end face of the ventral plate are provided with wedge strips whose shape and width are identical with and slightly larger than that of the V-shaped wedge groove channels respectively. The utility model has the advantages of firm connection, high bonding strength, availability for industrial assembly and production, simple technique and high working efficiency.
Description
Technical field
The utility model relates to construction formwork supporting structure and timber buildings house haunched member, relates in particular to wood, bamboo class i beam.
Background technology
In building construction and road and bridge construction, need use support shuttering during placing of concrete, generally support crossbeam in the form bracing system of Shi Yonging and secondary beam have wooden frame, girder steel, aluminum alloy beams etc., and wooden class i beam is widely used owing to cost is low.Use the joist of wooden H-beam in a large number abroad in America and Europe, Japan etc., and then replace traditional solid wood beam as the timber buildings house.There is the not high problem of bonding strength between web and the wing plate in wooden H-beam commonly used at present.Chinese patent CN2801933Y discloses a kind of i beam, and swallow-tail form head and the swallow tail shaped slot formation of splicing is adopted in the junction of its web and wing plate.Its wing plate adopts monolithic or split-type structural.When wing plate adopts monolithic construction, when assembling, the swallow-tail form head of web bit by bit must be inserted the side end face of swallow tail shaped slot from the wing plate along its length,, can only finish by hand assembled because i beam is very long.When wing plate adopts split-type structural, wing plate is by outer wing plate and be connected that wing plate constitutes in portion about the outer wing plate inboard a pair of, during assembling, with about the inner termination of two blocks of interior wing plates be bumped into the both sides of web swallow-tail form head respectively, then again outer wing plate is connected as a single entity by nail and interior wing plate; This structure will adopt hand assembled equally, and outer wing plate and interior wing plate fix by nail, and its bond strength is not high.The i beam of this structure is owing to can't adopt industrial-scale production, and work efficiency is low.
The utility model content
The utility model aims to provide a kind of bonding strength height, can carry out the type of wood and bamboo i beam of industrialization Assembling Production.
The technical scheme that the utility model adopted is: a kind of type of wood and bamboo i beam, comprise web and be vertically connected on the web, the wing plate of following both sides, it is characterized in that: on, be equipped with the dovetail groove of inner wide and outer narrow on the lower wing plate along its length, web is a rectangular structure, its thickness matches with the width at wing plate upper trapezoid groove notch place, on it, be equipped with v shape wedge groove on the lower surface along its length, on the web, the lower end is bumped into respectively, in the dovetail groove of lower wing plate, on the web, being provided with shape in the v shape wedge groove on the lower surface matches with it, width is slightly wider than the spline of wedge groove.
Be equipped with a v shape wedge groove on the upper and lower end face of described web.
Be equipped with a plurality of v shape wedge grooves on the upper and lower end face of described web.
Described web can adopt finger or mitered to be combined into along its length.
Described wing plate can adopt finger or mitered to be combined into along its length.
The beneficial effects of the utility model are: (one) matches with the width at wing plate upper trapezoid groove notch place (being the narrowest place of dovetail groove) owing to web thickness, the upper and lower end face of web is provided with v shape wedge groove, put spline earlier in the v shape wedge groove, just the upper and lower end of web directly can be bumped in the dovetail groove of upper and lower wing plate by assembly equipment again, spline is embedded in the v shape wedge groove when web is bumped in the dovetail groove of wing plate fully, the upper and lower end of web is expanded into bathrocephaly, closely cooperate the bond strength height with the dovetail groove of wing plate; (2) can realize suitability for industrialized production, technology is simple, the work efficiency height, and the production cost is low.

Fig. 3 is the front view of another embodiment median ventral plate of the utility model.
The specific embodiment
The structure of an embodiment of the utility model, as shown in Figure 1 and Figure 2, a kind of type of wood and bamboo i beam, comprise web 3 and the upper flange 1a, the lower wing plate 1b that are vertically connected at web both sides about in the of 3, wing plate and web 3 are rectangular structure, are equipped with the dovetail groove of inner wide and outer narrow on the upper surface of the lower surface of upper flange 1a and lower wing plate 1b along its length; The thickness of web 3 matches with the width at wing plate upper trapezoid groove notch place (being the narrowest place of dovetail groove), its upper and lower end face upper edge length direction is equipped with a v shape wedge groove 31, be provided with the spline 2 that shape matches with it, width is slightly wider than the wedge groove in the v shape wedge groove 31, the upper and lower end of web 3 is bumped into respectively in the dovetail groove of upper flange 1a, lower wing plate 1b.
Web and wing plate can be solid wood or timber wood-based plate, and artificial bamboo board, web and wing plate can adopt finger or mitered to be combined into along its length.
During assembling, in the dovetail groove of upper flange 1a and lower wing plate 1b, apply glue earlier, in the v of web 3 shape wedge groove 31, put the spline 2 that was coated with glue, the pressurization by assembly equipment then directly is bumped into the upper and lower end of web 3 in the dovetail groove of upper flange 1a and lower wing plate 1b, spline 2 is embedded in the v shape wedge groove 31 when web 3 is bumped in the dovetail groove of wing plate fully, the upper and lower end of web 3 is expanded into bathrocephaly, closely glued together with the dovetail groove on the wing plate, the bond strength height.Whole assembling process can realize industrial-scale production, the work efficiency height, thus production cost of products is reduced.
The structure of another embodiment of the utility model, as shown in Figure 3, as different from Example 1, web 3 upper and lower end faces are provided with two v shape wedge grooves 32, are provided with the spline that shape matches with it, width is slightly wider than this wedge groove in the v shape wedge groove 32.When the thickness of web is thicker, the spline in v shape wedge groove the upper and lower end of web 3 can't be expanded into wing plate on the close-fitting shape of dovetail groove, offer 2 or a plurality of v shape wedge groove this moment on the upper and lower end face of web 3, just can address this problem.
