In the present invention, adhesive glue can be used epoxide-resin glue.
The present invention has adopted the combination of both direction,
Combination along the length direction of beam:
For large span wooden frame, because timber to be spliced is the sheet material of multistage normal length, common diameter class, its lengthShort, longitudinally need splicing, connecting method is taked tenon tooth connected mode, is the resistance to tension that improves splicing node, with profound in tensile regionMilitary rock fiber cloth is wrapped up in to apply and is strengthened.
Combination along the thickness direction of beam:
The wood plank through-thickness assembly that combination wooden frame has spliced by aforementioned length combination mode with several, forImprove resistance to tension and the holistic resistant behavior of the cementing plank of tensile region, be chosen in respectively tensile region time one deck and bottom gluePaste one deck basalt fibre plate. In order to improve wooden frame holistic resistant behavior, laterally the joint of adjacent panels needs the fissure of displacement in addition.
Pre-bending method applies prestressing force:
Pre-bending ratio juris is: wooden frame member is fixed on two end bearings, utilizes loading equipemtn to member span centre following tableFace applies load vertically downward. Make member produce certain predeformation. Hold carry in the situation that, basalt fibre plate is sticked onOn compression face. Under natural conditions, maintenance can be worked with member jointly to reinforcing material, and released load utilizes the resilience of beam to producePretension. Finally beam is fallen to turnback, form prestressed girder member. The method is not only constructed simply, and prestress application essenceDegree is controlled better. Because the mode of pre-bending is equivalent to the prestressing force primary moment with predetermined external load opposite direction to one of wooden frame.Make the first tension of wooden frame compressive region fiber, the first pressurized of tensile region fiber, becomes one by the stretch-draw of basalt fibre plate with wooden frame pressurized bendingIndividual internal force balance system, thus effectively bring into play the intensity of high-strength basalt fibre plate, can improve the ultimate bearing of memberPower and bending rigidity, reduced the distortion of wooden frame. Particularly for basalt fibre plate, due to the ultimate tensile strength of Wood in Common UseOnly existLeft and right, and the limiting strain of basalt fiber material existsLeft and right, limiting strain differsGreatly, if do not apply prestressing force tensile region wood-fibred break, basalt fibre does not still play a role completely. If can be profoundBetween military rock fiberboard and tensile region wood-fibred, set up strain phase error, in the time that wooden frame is subject to curved destruction, twoPerson has reached limiting strain simultaneously, has brought into play the intensity of material completely, is also therefore most economical.
