Description
Technical field
The invention belongs to civil engineering structure fields, and in particular to a kind of modern times bamboo structure house, wooden frame structure and bamboo
The bamboo wood split beam that wooden frame structure uses.
Background technique
Chinese bamboo timber resource very abundant, either planting number, area and accumulation or bamboo product and its processing water
It is flat, first of Chan Zhu state, the world Jun Ju.Bamboo wood has intensity height, good toughness, wear-resistant, texture straight, color elegance etc. a variety of excellent
Point, many good characteristics with Hard―Wood, are the ideal materials of building trade.Bamboo wood also has with short production cycle, again
The strong feature of natural disposition.Bamboo timber resource is developed and used, " wood substituted by bamboo " is to alleviate one of contradictory effective way of timber supply and demand.
House is built using bamboo wood, has quite long history.Although can produce centainly using the building of former material circle bamboo
Art and architectural effect, be probably difficult to become main structural material is widely applied in modern architecture industry.Its reason has:
(1) geometry of raw bamboo bar is single, causes construction style dull;(2) geometry of raw material irregularly leads to waste and discomfort
Close modern construction program;(3) node is sufficiently complex, often results in and connects unreliable or be not connected firmly, seriously affects building
Comfort level;(4) raw bamboo itself there are serious anisotropy and transverse strength it is extremely low;(5) although single bamboo bar can undertake self weight,
But the limited diameter of single former material after all then must tie up bunchy using the garden Duo Gen bamboo to increase as structure load-bearing material
Construct difficulty;In the case where unprocessed, bamboo wood easily damages by worms, rotten and mildew etc..
The bottleneck for how breaking through raw bamboo development and utilization, widens the application field of bamboo, realizes the efficient and rational benefit of bamboo resource
With being the problem that vast bamboo producing region is faced, bamboo wood is the bamboo that fast-growing, short-period moso bamboo are processed into certain specification
Piece, drying to moisture content 8%~12%, then there is the dimension stock in the rectangular section of equidirectional glued by bamboo sheet by adhesive
The characteristics of elasticity modulus is high, mechanical strength is high, easy processing.For raw bamboo beam, joggle beam possesses higher above and below bamboo wood
Bearing capacity, better deformation performance and superior ductile performance, be effective to solve to restrict ecological environment-friendly type bamboo and wood knot
One important channel of structure architectural development has very wide market application prospect.
Summary of the invention
Purpose to be solved by this invention is intended to break through the bottleneck of raw bamboo development and utilization, widens the application field of bamboo, gram
Take the disadvantages of raw bamboo joist support loading capability is low, ductility is poor and deformation performance is poor, provide a kind of mechanical property it is good, it is low in cost and knot
Joggle beam above and below the simple bamboo wood of structure, can be used as floor beam and roof girder is applied in bamboo-wood structure building.
In the present invention, joggle beam includes upper beam, underbeam, round steel pin, circle bamboo tenon, five part of glue-line to bamboo wood up and down.
Wherein: upper beam is located at the top of joggle beam, and underbeam is located at the bottom of joggle beam, and round steel pin is vertically implanted into upper beam tenon and underbeam card
In slot, circle bamboo tenon is vertically implanted into upper beam and underbeam, and glue-line is located at the middle part of upper beam and underbeam.
Basic principle of the invention is as follows: upper beam is arranged in split top surface of the beam, mainly undertakes pressure;Underbeam is arranged in split
Soffit mainly undertakes pulling force;Round steel pin is vertically implanted into upper beam tenon and underbeam card slot, mainly undertakes shearing force;Circle bamboo tenon
In vertical implantation upper beam and underbeam, shearing force is mainly undertaken;Upper beam tenon is embedded in underbeam card slot, mainly undertakes shearing force;It is located at
Glue-line between upper beam and underbeam interface mainly undertakes shearing force.
The upper beam and lower depth of beam are equal, and upper beam and underbeam fit closely, interface brushing glue-line.
The viscose glue interface of the upper beam and underbeam should carry out dabbing processing, and chisel depth is 1~2mm, and chisel trace is about 20mm,
Cutting rate is not less than 80%.
Along the tenon of beam length direction equidistant arrangement, underbeam top is arranged and tenon distributing position for the upper beam bottom setting
The card slot to match, the height of upper beam tenon are equal to the depth of underbeam card slot, and tenon width 1.0mm~1.5mm bigger than card slot is left
The right side, the tilt angle of tenon and the tilt angle of card slot match each other.
The round steel pin is vertically implanted into the tenon of upper beam and the card slot of underbeam, and round steel pin diameter is than tenon and card slot
Big 1.0mm~1.5mm of prebored hole or so, implantation depth take 5 times of round steel pin diameter and the larger value of both 50mm.
The circle bamboo tenon is vertically implanted into upper beam and underbeam, and circle bamboo tenon diameter is bigger than the prebored hole of upper beam and underbeam
1.0mm~1.5mm or so, implantation depth take 6 times of round bamboo tenon diameter and the larger value of both 60mm.
The glue-line should select crosslinking binder, using epoxide-resin glue, urea-formaldehyde resin adhesive or phenolic resin glue.
The present invention has widened the application field of raw bamboo, overcomes some known disadvantages of raw bamboo beam, above and below bamboo wood
Sectional mo(u)ld beam has following significant effect:
(1) raw bamboo is lower in the added value of product and technology content of traditional field, and bamboo is processed into bamboo wood and is answered
For engineering field, the application field of bamboo can have greatly been widened, has been conducive to vast bamboo producing region additional income.
(2) round steel pin and circle bamboo tenon are configured to the neutral axis of bamboo wood joggle beam, round steel pin and circle can be given full play to
The high advantage of bamboo tenon shear-carrying capacity, and greatly improve joggle beam element mechanics performance and ductility.
(3) glue-line for being set to upper beam and underbeam interface can give full play to the higher shear-carrying capacity of adhesive, can be compared with
The relative slippage of small upper beam and underbeam, to improve the initial anti-bending bearing capacity of joggle beam.
(4) relative to masonry structure and reinforced concrete structure, the production of bamboo wood joggle beam and process environment are dirty
It contaminates small, reduces the usage amount of non-renewable resources, reduce the energy-output ratio in use process;Relative to timber structure, hold
Loading capability is bigger, and span ability is stronger, and ductility and automatic recovery ability are more preferable.
