Abstract

The utility model relates to a steel and wood composite beam, which is composed of wood and steel which are glued. The centers of two half circular wood with the same diameter are embedded in a steel tube connected with a sleeve pipe, the two half circular wood and the steel pipe are fixedly glued by adhesive, and then, a U-shaped bolt penetrates through the wood to fasten. Because the steel pipe only extends into the half of the sleeve pipe, the other half sleeve pipe can be connected with the other composite beam. At the time, the connection of two composite beams is added with a ferrule, so that the body of the beam is lengthened. If used single beam without lengthening, the steel pipe can be lengthened, and the sleeve pipe can not be needed. The utility model effectively lengthens the strength of the wood, can serve as the beam, and can serve as the column. The utility model has the advantage of wood saving, and reduces the worker's labor intensity.

Description

Steel and wood composite beam

The utility model relates to a kind of steel wood composite beam, belongs to a kind of construction.

The vast rural area of China, dwelling house is many based on wooden construction, adopts timber to make beam, post, purlin etc., and consumption of wood is very big; This is mainly due to adopting modern steel work or reinforced concrete structure, makes, transportation, inconvenience is arranged more than the construction, is not suitable for the common peasant of unshared housing and adopts; But timber itself then has the shortcoming of itself, mainly is that supporting capacity is low, and volume is big, and it is many to take up room, and is rotten easily in short supply with timber resources, and during use, also relatively heavier, labor strength is big, so convenient inadequately.

The purpose of this utility model is that a kind of steel wood composite beam will be provided, and it has improved the supporting capacity of wooden frame, alleviates labor strength, has saved timber, and firm durable.

The purpose of this utility model is achieved in that this steel wood composite beam, by timber and bonding the forming of steel combination, is about to two half round timber centers that diameter is identical, embedding is connected with the steel pipe of sleeve pipe, and with adhesive half round timber and steel pipe are cemented, and then use U bolt, pass that timber is fastening to form, the invar pipe only stretches into half of sleeve pipe, second half sleeve pipe exposes and can use when connecting another root composite beam, at this moment, and again in two junctions, add cuff, beam body lengthening.When not needing spreading as single use, then available elongated steel pipe is without sleeve pipe.

The utility model advantage:

1, improved strength of wood effectively, with the wooden frame comparison of same intensity, in light weight, volume is little, occupies little space, and easy construction alleviates labor strength.

2, save timber, social benefit is good: according to statistics, build common three-bed room wooden construction house, need consumption timber 2m ³, use the complex beam-column material instead, can save timber 1/2, dead load alleviates more than 1/3, corresponding reducing cost, and bearing capacity increases.

3, firm durable: because of used steel are positioned at the timber center, and wrapped up by adhesive, so be difficult for corrosion, in the composite beam joint, have cuff, sleeve pipe to be connected, the timber exposed face applies coating again, can increase the service life.

4, applied widely: as both can to bear moment of flexure, and also can bear pressure, and can make beam, and also can make post, as support material of mine etc.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is the utility model perspective exploded view.

Fig. 2 is the utility model schematic perspective view.

Fig. 3 is the utility model cut-away section schematic perspective view.

Describe in detail below in conjunction with accompanying drawing.

With reference to Fig. 1-3, this steel wood composite beam is by steel and wood combination is bonding forms, and two half round

timbers

1,2 that timber is scraped for the diameter same level have semicircle chamfer putting steel tube 8,8 at half round

timber

1,2 centers ₁, at chamfer putting steel tube 8,8 ₁The top is provided with the bigger semicircle bushing slot of diameter 7,7 ₁, the plane 13 of half round

timber

1,2 ₁, on 13 the plane, be provided with the bolt hole 10,10 of mutual correspondence ₁, 9,9 ₁, 15,15 ₁, 14,14 ₁Steel are that steel pipe 3 reaches and the sleeve pipe 4 of steel pipe 3 to be threaded, and steel pipe 3 matches with chamfer putting steel tube and bushing slot respectively with sleeve pipe 4; Have the steel pipe 3 of sleeve pipe 4 in 1,2 embeddings of timber, make sleeve pipe 4 stretch out an end of half round timber, and with adhesive with two half round timber planes 13,13 ₁Reach steel and cement, the bolt hole 11 that U-shaped fastening bolt 5 passes on half round

timber

1,2 and the fastener member 6 is fixed the composite beam after bonding; Half of 3 threading 4 length of steel pipe is screwed into steel pipe usefulness during second half another root composite beam to be connected, and is provided with cuff two junctions.The U-shaped fastening bolt that cuff and composite beam top are used among the figure is not shown, and 12 are the fastening bolt nut.The general available latex of adhesive therefor.

When composite beam does not need spreading,, can only adopt elongated steel pipe 3 and do not establish splicing sleeve 4, the corresponding manufacturing process of having simplified at the timber center.
