Abstract
A shaped ply-bamboo for building is prepared from raw bamboo through splitting the raw bamboo to become bamboo strips, drying, applying adhesive, laminating, hot pressing, cold pressing, sawing by needed size, splicing and gluing. It can be used as the bearing beam or column of building.
Description
Technical field
The present invention relates to a kind of building structure bamboo wood section bar and manufacture method thereof.
Background technology
The growth cycle of pure natural material---bamboo is fast, and fiber is hard, density is big, moisture is few, healthy, environmental protection, thereby the development and use bamboo wood has become the fashion of today.With the bamboo wood is raw material, and by bamboo chip lamination hot pressing mode, the technology of making sheet material is known already.But this sheet material is mainly used in aspects such as cement formwork, and mainly adopts the mode of bamboo chip quadrature to the assembly gummed.Bamboo laminated plate is used for building structure section bar manufacture view does not see relevant report as yet.Since the particularity of load bearing section bar force-bearing situations such as the beam of building structure usefulness material standard, post, the bamboo wood sheet material that adopts above-mentioned prior art to make, and physical and mechanical properties such as its intensity are difficult to reach the performance standard requirement of architectural shape.
Summary of the invention
The purpose of this invention is to provide a kind of firm, durable building structure bamboo wood section bar and manufacture method thereof, its superiority just is for building bamboo material stacked material that adopts specific bamboo chip arrangement mode to produce function admirable and finally makes the bamboo wood section bar that this bamboo wood section bar can satisfy the building structure performance.
Realize that by the present invention this kind building structure mainly finished by two step process routes with the manufacturing of section bar: the first step, the manufacturing process of bamboo cord wood; Second step, the building structure manufacturing process of bamboo wood section bar.
For achieving the above object, the present invention takes following design:
A kind of building structure bamboo wood section bar manufacture method is characterized in that described method is as follows:
1) the bamboo bar that the thick bamboo tube rip cutting is grown up;
2) cut off the thin bamboo plate that the bamboo bar becomes certain specification;
3) bamboo chip gas is done 8～15% moisture content;
4) be immersed in applying glue in the glue;
5) pull out, drop removes unnecessary glue, and the bamboo chip that will contain glue is dried to moisture content 10～20%;
6) with the dried bamboo chip of impregnation with the ad hoc fashion assembly;
7) send the bamboo chip of assembly to go into hot pressing in the hot press;
8) sheet material after the hot pressing is sent in the cold press colded pressing;
9) receive the lamination sheet material that seamless makes.
Building structure bamboo cord wood by said method is made has its specific assemble pattern.It is by many groups of stacked long-pending the forming of some forward bamboo chips, or is is forward inserting and putting some cross-levels between the bamboo chip layer, or on the top layer the one or more layers of bamboo weaving mat with glue or the complex method of above three kinds of situations is arranged.
Advantage of the present invention is: the wide material sources that process raw material, performance are splendid; The bamboo laminated plate performance that adopts manufacture method of the present invention to make can satisfy building structure section bar performance indications requirement.
Description of drawings

Fig. 2 is a manufacture method schematic flow sheet of the present invention
The specific embodiment
As shown in Figure 1, bamboo cord wood of the present invention is in the bamboo chip mode of lamination 1 gummed forward, adopt a certain proportion of quadrature to make the bamboo laminated plate material for balance layer simultaneously, utilize the bamboo chip intersection lamination mode of the different numbers of plies, diverse location to solve the problem on deformation of structure with bamboo laminated plate to bamboo chip laminated layer 2; Or bamboo weaving mat with glue more than one deck is arranged with the transverse strength of improving material with solve the distortion of materials problem on the top layer.And be stock with this bamboo chip laminated board, make the plate square bar and the section bar that can satisfy spandrel girder for building, column performance index according to certain size (length and width, thick).
With in the manufacturing process of bamboo laminated plate, circular bamboo pole at first is cut into the bamboo section with certain-length in first step building structure, and being split into thickness by artificial or mechanical means then is 0.3～1.5mm, and width is the bamboo chip of 20～30mm.Bamboo chip is after suitable drying, and the method by impregnation or spray glue is at its top sizing.The applying glue kind comprises phenol glue, cyanurotriamide modified urea-formaldehyde glue or resorcinol-glutol mixture.Bamboo wood after the applying glue is after drying is handled moisture content 5%～15% again, according to the requirement of panel density and thickness, in mode forward bamboo chip arranged assembly and forms blank.According to the application site difference of material in structural lumber (as the web of I-beam, rafter bar etc.), and the different requirements of material force way, the lamination mode of bamboo chip can be carried out in various degree on lamination forward is main basis, the bamboo chip quadrature of different parts is to the assembly lamination and use the bamboo mat material.Form sheet material by hot pressing behind bamboo chip behind the impregnation or the bamboo mat assembly.Hot pressing temperature, time and hot pressing pressure are adjusted according to bamboo wood properties of materials and panel density.General hot pressing temperature is 100～180 ℃, and hot pressing time is 1～1.5min/mm (according to the bamboo chip moisture content), and hot pressing pressure is 1～10MPa.In hot pressing, also can adopt the pressurization cooling provision to reduce the distortion of sheet material.
The manufacturing of the second step building structure section bar is mainly carried out according to the following steps: with the size that the bamboo laminated plate material that suppresses becomes to stipulate according to different purposes sawings, pass through the finger bonding technique then with the sheet material spreading; By with modes such as bonding or metalwork is fixing make the sheet material thickening form thicker plate square bar with resorcinol adhesive after the plate surface sanding.By mortise, fluting, modes such as combination, pressing are combined into sheet material the section bar (as I-beam, clamping plate post etc.) of regulation shape and size again.
The present invention is further described below in conjunction with embodiment
Embodiment 1: as shown in Figure 2
(1) the bamboo bar of at first the thick bamboo tube rip cutting being grown up;
(2) it is thick thicker bamboo bar further to be cut off into 0.3～1.5mm, and the thin bamboo plate that 20～30mm is wide will be difficult for bonding top layer bamboo chip simultaneously and reject;
(3) gas is done, and bamboo chip is done 8～15% moisture content at gas stove room gas;
(4) impregnation is immersed in it in the phenol glue about 30%～40%.The applying glue kind also comprises cyanurotriamide modified urea-formaldehyde glue or resorcinol-glutol mixture except that phenol glue.The final resin added about 8% of bamboo chip;
(5) drying, treat that all there is glue on whole bamboo chips surface after, pull out and drop removes unnecessary glue.The bamboo chip oven dry or the gas that will contain glue are done moisture content about 15%;
(6) assembly according to the requirement of sheet metal thickness and density, is formed slab with the dried bamboo chip of impregnation in the rift grain mode.Structural lumber density is generally 0.85～1.00g/cm
