Description
Technical field
The present invention relates to a kind of construction tool for building more particularly to a kind of glass reinforced plastic for construction group mould are compound
The wooden a tree, used in making timber for boats.
Background technique
Backing material for building generally comprises the wooden a tree, used in making timber for boats and compound wood brace in the prior art.In China Patent No.
A kind of method for manufacturing of sham wood a tree, used in making timber for boats is disclosed in " 97112278.4 ", the applying date is on July 21st, 1997, publication date
It is the veneer of general species successively to be carried out in the solution based on H2O2 bleaching, in certain temperature on January 27th, 1999
Acid dyes solution in dyeing, steam or dielectric drying, sorting, assembly, select glue kind gluing, cold pressing or hot pressing, slicing etc.
Process.But such wood a tree, used in making timber for boats is not intended as construction tool use, and is merely possible to the decorative panel of construction material.In the prior art
In, construction is lower with the wooden a tree, used in making timber for boats intensity and recycling rate of waterused, but is largely using, the existing building construction wooden a tree, used in making timber for boats of tradition
Mode is one of timber consumption maximum.
Existing compound wood brace is all the compound wood brace using steel and wood composite preparation.For example, in China Patent No.
" 200720080728.5 " disclose a kind of compound wood brace used for reinforced concrete member shaping support, and the applying date is 2007 8
The moon 21, publication date are on June 11st, 2008, and steel frame uses C-type steel frame, and the wooden a tree, used in making timber for boats is entrenched in C-type steel frame, steel
Face is equipped with connecting hole, is fixed together C-type steel frame and the wooden a tree, used in making timber for boats to form an entirety with connector, in C-type steel frame steel
Face is equipped with the construction circular hole that distance does not wait.For another example China Patent No. " 200920243850.9 " discloses a kind of compound wood brace branch
Support structure part, the applying date are on December 9th, 2009, and publication date is on October 27th, 2010, including by " ∪ " shape channel steel and is filled out
The supporting structure ontology for filling wood formation, filling timber is set as assuming a " convex " shape, the two channel steel sides of " ∪ " shape channel steel bend inwards
Extend and cooperatively forms a plane with the nose of filling timber.Existing compound wood brace preparation method mainly by steel plate bending and is cut
Compound wood brace is made at required shape, then with wood composite.
But it finds in practical applications, mainly there is also following deficiencies for existing steel wood compound wood brace：One, the prior art
Compound wood brace is all the external reinforcing set using steel as the wooden a tree, used in making timber for boats, and excess enthalpy is heavy, is especially reused in the construction process
Afterwards, cement slurry can be poured into largely in the gap between reinforcing sleeve and the wooden a tree, used in making timber for boats, keep compound wood brace heavier, so that as support
Compound wood brace recycling is more difficult, not only increases the consumption of timber greatly, is unfavorable for environmental protection, and increase and apply
Work cost.Two, in the construction process, compound wood brace needs placing flat on steel tube frame, since compound wood brace is more heavy,
And meet water between steel compound wood brace and steel pipe and be easier to slide, there is biggish security risk.Three, reinforcing sleeve of the steel as the wooden a tree, used in making timber for boats
Higher cost.Four, reinforcing sleeve made of steel is connect with the wooden a tree, used in making timber for boats using screw, and the screw and nut boss of connection are in steel wood
Compound wood brace is got on or off the bus the protective layer on reinforcing sleeve surface easy to damage during hoisting transportation, so as to shorten steel wood compound wood brace
Service life.Five, steel wood compound wood brace is supported for the external corner of beam, also needs mating other tools, such as ability when in use
Domain is known as the tool of poker, due to the protrusion of attachment screw and nut, prevent the plank of connection from compound wood brace comprehensive engagement,
So that the stability that poker positions composite shuttering is bad.
And the more wide model of the application range of glass reinforced plastic, such as Aeronautics and Astronautics, military affairs etc. in the prior art.And it is building
It is also related in field, such as China Patent No. " 99102010.3 " discloses a kind of bamboo/glass reinforced plastic composite light construction material,
Its applying date is on 2 5th, 1999, and publication date is on August 9th, 2000, is the bamboo that is abounded with using south China as primary raw material,
As the main load-carrying member of structure, it is cladded with or winding fibre reinforced composites, central filler filler is combined, the material
Structure can be made into the bearing bar and panel construction of various types and shape, be only used for rod piece used in light construction structure and wall
Plate and skyscraper partition wall.Thus used in the prior art only as light-weight building material.Since glass reinforced plastic is in the presence of as follows
Defect：One, elasticity modulus is low, and the modular ratio timber of glass reinforced plastic is twice big, but 10 times smaller than steel, therefore in product use
Often feel rigid deficiency, is easily deformed.Two, long-term temperature tolerance is poor, and general glass reinforced plastic cannot be used for a long time at high temperature, general poly-
Ester FRP is just decreased obviously in 50 DEG C or more intensity, general only used below at 100 DEG C；Universal epoxy FRP at 60 DEG C or more,
Intensity decreased significantly.Three, aging phenomenon, aging phenomenon are the common defects of plastics, and glass reinforced plastic is no exception, ultraviolet light,
It is easy to cause performance to decline under the effects of dust storm sleet, chemical mediator, mechanical stress.Four, interlaminar shear strength is low, interlayer shear
Intensity undertakes by resin, so very low.Drawbacks described above makes glass-reinforced plastic material be not easy to connect, and reliability after connection
Poor, there are biggish security risks, so that glass-reinforced plastic material is only used as construction material in the field of construction, and cannot
It is used as construction material.
Summary of the invention
It is an object of the invention to overcome the above problem existing for the existing wooden a tree, used in making timber for boats and steel wood compound wood brace, one kind is provided and is used for
The glass fiber reinforced plastics composite wood balk of construction group mould, the present invention are compound using glass reinforced plastic and the integral formation glass reinforced plastic of wood composite
The wooden a tree, used in making timber for boats improves the strength and stiffness of compound wood brace, overcomes defect existing for glass reinforced plastic itself, and glass fiber reinforced plastics composite wood balk with
Construction tool is with the use of relatively reliable.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of glass fiber reinforced plastics composite wood balk for construction group mould, including compound sleeve and the wooden a tree, used in making timber for boats, it is characterised in that：It is described
