Description
Technical field
The present invention relates to a kind of building materials and preparation method thereof, relate in particular to arched girder of a kind of large-scale plastic tunnel that is mainly used in mariculture, growing vegetables, fruit production and preparation method thereof.
Background technology
The most of iron and steel that uses of the arched girder of existing large-scale plastic tunnel is processed because ambient humidity is big in the booth, especially mariculture in booth in the air salinity big, iron and steel is easy to corrosion, influences service life, and iron and steel arched girder cost is also higher.Other has a kind of arched girder to use the curing of magnesia oxychloride cement adding glass fibre to form, though cost greatly reduces, efflorescence easily, the anti-halogen that makes moist in wet environment descend its intensity, and might take place ruptures suddenly collapses, and causes potential safety hazard.In order to solve these technical problems; Go into carried out some useful explorations; Like publication number is that the Chinese invention patent " new waterproof greenhouse bracket and preparation method thereof " of CN101305680B discloses a kind of technical scheme; Draw in the pvc pipe material gradually glass fiber mesh and the magnesia oxychloride cement of filling simultaneously, form through 4-7 hour curing.But because behind the glass fiber mesh entering pvc pipe material; Its fold the pipe in distribution be at random with uncontrollable; Especially when the pvc pipe material axially be bending the time during when appearance making arched girder; Glass fiber mesh is will be at the lower edge place of bending intensive and almost do not have at other positions, causes whole arched girder intensity everywhere inconsistent, is easy to rupture at weakness; Because the charges major part in the pvc pipe material by the magnesia oxychloride cement filling, makes manufactured goods very heavy, be unfavorable for transportation and construction simultaneously; Also owing to the charges in the pvc pipe material just are made up of magnesia oxychloride cement and glass fiber mesh; When in the large-scale plastic tunnel that compression and tensile strength is had relatively high expectations, using in order to satisfy requirement of strength; Certainly will want the enlarging section size, and this has further caused the raising of waste, transportation and difficulty of construction of raising and the raw material of cost.
Summary of the invention
The objective of the invention is to solve the deficiency of prior art and develop a kind of in light weight, compression and tensile strength booth arched girder that intensity is consistent and preparation method thereof greatly, everywhere.
For realizing above-mentioned purpose, technical scheme provided by the invention is:
The booth arched girder; Monomer beam 10, Lian Liang hoop 11, stainless steel screw 12 two band radians are formed by connecting; Monomer beam 10 comprises the inserts that round rectangle tubular shell 1 and housing 1 contain; Inserts is made up of chloro-magnesium cement and aggregate, and described aggregate comprises glass fiber mesh 3, bamboo chip 4-1, reinforcing bar 4-2, steel pipe 4-3, plastic foamboard 5.
In order to improve compression strength weight reduction simultaneously, described housing 1 is the PVC section bar, and the height in its cross section is greater than width.
Preferred version is that described that to connect beam hoop 11 be one section axial curvature, cross sectional shape is identical with monomer beam 10 and can hold monomer beam 10 and insert the PVC section bar of cooperations.
For the ease of installing, described that to connect beam hoop 11 be one section axial curvature is identical with monomer beam 10 and can hold the U-shaped PVC section bar of monomer beam 10 insertions.
In order to further facilitate installation and to reduce cost, described even beam hoop 11 is two height and the corresponding PVC sheet material of monomer beam 10 depth of sections.
The preparation method of booth arched girder comprises the steps:
Get the raw materials ready: housing 1 heating is bent to arch; With soft do a bamboo chip 4-1 with iron wire tie up the back or the both sides up and down of plastic foamboard fit at least one bamboo chip 4-1 or at least one reinforcing bar 4-2 or at least one steel pipe 4-3 and tie up with iron wire after; Again with glass fiber mesh twine the 2-4 circle form with housing 1 length quite, Gao Kuanjun is less than the high wide aggregate aggregate of housing 1 internal diameter, and connects a stay cord 6 at an end of aggregate aggregate; Configure the chloro-magnesium cement slurry of magnesium chloride and magnesia mixing according to conventional method;
Filling: the free end of stay cord 6 is passed housing 1 and pulls out from the other end, make the aggregate aggregate get into housing 1, the chloro-magnesium cement slurry is injected housing 1 on one side, starch and aggregate is full of the inside of whole housing 1 until chloro-magnesium cement Yi Bian spur stay cord 6 then;
Solidify: leave standstill at normal temperatures and formed monomer beam 10 in 7-14 days;
Assembling a: end of two monomer beams 10 is cut into interengageable end face according to curvature, binds round 11 with few four stainless steel screws 12 and Lian Liang again two monomer beams 10 are connected into an integral body.
In order to prevent that end face exposed after 10 interceptings of monomer beam from producing anti-halogen, efflorescence, behind brushing waterproof coating on the end face, bind round 11 with at least four stainless steel screws 12 and Lian Liang again two monomer beams 10 are connected into an integral body.
The present invention compared with prior art owing to adopt bamboo chip and glass fiber mesh as aggregate, had not only increased the tension compression strength of booth arched girder but also had alleviated the overall weight of booth arched girder; Foamed plastics is placed into the center of booth arched girder, and not only having alleviated the overall weight of booth arched girder greatly but also made the booth arched girder form waller effect has increased compression strength; The depth of section of employing beam can satisfy the overall weight that compression strength can reduce the material usage amount again, reduce the booth arched girder greater than the technical scheme of width; Use independent preparation to accomplish the monomer beam and then be assembled into the booth arched girder, process the booth arched girder because length reduces half than disposable, easy to operate simple, reduce mass defects such as producing cavity simultaneously, easily the quality assurance unanimity.
