Description

A kind of continuous bamboo wood stirrup production method of annular
Technical field
The present invention relates to a kind of stirrup production method, especially a kind of continuous bamboo wood stirrup production method of annular belongs to soil Wood engineering field.
Background technique
Stirrup be so that various reinforcing bars in beam column component is constituted the muscle materials of frameworks of steel reinforcement for fixing the position of main reinforcement, and Being coupled stress main reinforcement and compressive region concrete makes its co-operation.Stirrup is used to connect stress main reinforcement and frame reinforced bar and make in beam Formed framework of steel reinforcement, be primarily subjected to shearing and torque, beam in curved scissors area by by shearing and moment of flexure collective effect, in shear span Principal tensile stress trace is slanting in section, will generate diagonal crack, due to stirrup be it is vertical, intersect with diagonal crack, thus can hinder Only or limitation diagonal crack Emergence and Development.Stirrup fixes stress longitudinal reinforcement in column, prevents vertical muscle stress buckling, improves The ductility of component.When using tie hoop, moreover it is possible to which confined concrete is at three dimension stress state, improves the anti-of concrete Compressive Strength.Therefore, stirrup is widely used in concrete component, and quantity consumed is huge, finds substitution reinforcing bar stirrup Material becomes reduction project cost, develops the certainty of low-carbon building.
Bamboo wood relies on excellent mechanical property, it is considered to be one of highest material of efficiency, tensile strength in nature With compression strength considerably beyond common wood, the ratio of strength to weight of bamboo wood substitutes reinforcing bar system with bamboo wood stirrup also above common iron Stirrup is ideal method.However, so far, the practical application of bamboo wood mainly also rests on interior decoration and building template layer Bamboo wood is used to make stirrup by face, and in terms of playing its binding effect, there are no excellent methods.Currently, bamboo wood stirrup is made, Multi-disc bamboo cane is mostly used to bind splicing method, binding splicing reliability is difficult to ensure that the progressive forming of full wafer bamboo wood annular is difficult, overlap joint Place is difficult to effectively connect.Manufacturing process is discontinuous, and stirrup overall performance is poor, and binding effect is insufficient, and is difficult to adapt to not similar shape The component of shape size, general applicability is poor, and there are many deficiencies.
Summary of the invention
The object of the present invention is to provide a kind of continuous bamboo wood stirrup production methods of annular, have obtained a kind of economical, durable Bamboo wood stirrup has expanded the scope and sphere of bamboo products application, takes full advantage of the high spy of bamboo wood good toughness, tensile strength parallel to grain Point, it is manufactured bamboo wood stirrup low-carbon, environmental protection, renewable, meet the policy of China's sustainable development, which is characterized in that pass through by The layer-by-layer continuous uniform of bamboo wood thin slice is wound in bamboo trunk, then by cutting method, is cut into the bamboo wood stirrup of preset width as needed, Making step is as follows:
1) it makes pipe mold: according to the size and shape of required bamboo wood stirrup, making corresponding pipe mold, and in pipe mold One layer of isolation film is wrapped up in outer surface, demoulds convenient for the later period;
2) bamboo wood impregnation: selecting the bamboo wood thin slice with a thickness of 0.1mm~1mm, bamboo wood thin slice resin glue is impregnated complete;
3) wind bamboo wood thin slice: by impregnated bamboo wood thin slice, in pipe mold outer surface, circumferentially layer-by-layer continuous uniform is twined Around, and roll pipe mold and make the winding of bamboo wood thin slice closely knit, resin glue is evenly distributed, and forms the bamboo trunk of winding shaping;
4) it conserving: the bamboo trunk of winding shaping is conserved in room conditions, maintenance duration is at least 24 hours, or Accelerate maintenance in baking oven or fog room, temperature setting is at 50 DEG C~150 DEG C, duration 4~12 hours;
5) it demoulds: after the completion of resin adhesive curing, bamboo trunk and pipe mold being mutually disengaged;
6) protect: bamboo trunk medial and lateral after demoulding carry out surfacecti proteon processing, manual brushing, dip-coating or spray gun spraying Separation layer 5 improves the durability of material;
7) it cuts: bamboo trunk is cut into the bamboo wood stirrup of preset width by cutting method.
The bamboo wood thin slice is wound by rift grain direction, and the angle of winding and the transverse direction of pipe mold are in 0 °, the number of plies of winding It is unrestricted.
The bamboo trunk cross section be circle, ellipse, rectangle, nose circle shape, number of edges > 4 regular polygon one kind.
The resin glue of the dipping is one of epoxy resin, vinylite, polyurethane resin, with curing agent Mixed proportion is controlled 1: 1~2: 1.
The painting brush material that the separation layer uses is vegetable oil, resin, cement-base composite material or asphaltic base composite wood One of material.
The invention has the following beneficial effects:
(1) scope and sphere for having expanded bamboo products application are substituted with bamboo wood stirrup or traditional steel wire binding bar are cooperated to make With, it is possible to reduce construction(al)steel amount saves building energy consumption, saves project cost.
(2) easy to operate, the high feature of bamboo wood good toughness, tensile strength parallel to grain is taken full advantage of, can be obtained good Binding effect meets the needs of structure normal use.
(3) bamboo wood stirrup is cut by the bamboo trunk that bamboo wood thin slice is continuously once wound, and full wafer bamboo wood stirrup annular is continuous Forming, can adapt to the component of different shape size, has the advantages that process strong operability, producing efficiency are high.
(4) bamboo wood stirrup low-carbon, environmental protection, renewable, meets China and pursues environmentally protective development model.
(5) bamboo wood stirrup avoids component from being influenced by external environment, and it is resistance under harsh environments that component can be enhanced Long property, and component surface aesthetics can be enhanced.
