Description

A kind of band divides the light steel pipe-timber with small diameter combination load-bearing pillar and the practice of chamber steel plate
Technical field
The present invention relates to light steel pipe-timber with small diameter combination load-bearing pillars and the practice that a kind of band divides chamber steel plate, belong to structure work Journey technical field.
Background technique
As the fast development of China's dwelling construction promotes house to meet the growing housing need of the people Industry modernization develops steel house, expands the occupation rate of market of steel house.It predicts light steel tube and timber with small diameter Reasonable combination is formed by structure and has broad application prospects.
With the continuous scarcity of resource, the timber resources in China is also faced with severe problem, since majority state should be through Embargo virgin wood, therefore dependence imported timber has become impossible, meanwhile, in use due to major diameter The favor of timber causes the timber of minor diameter (having a size of 40mm~130mm) seldom completely to be developed and used, most paths Timber is by serious waste.How the research that by timber with small diameter that people ignore is had become current hotspot is completely developed and utilized Problem, the solution of this problem not only will effectively alleviate crisis of resource, also solve forest reserves supply and demand to a certain extent Contradiction.
Carbon fiber becomes the emphasis of world today's material subject research with its excellent comprehensive performance.Research shows that: carbon fiber Tensile strength > 3500MPa of dimension, tensile modulus > 230GPa, density are only 1.76~1.94g/cm, have excellent mechanical property Energy and overall characteristic;Carbon fiber is used widely in building, the energy etc. field and industry.
Traditional reinforced column structural bearing capacity is generally poor, is needed in work progress using a large amount of (wood) mould Plate be easy to cause the serious waste of resource, while construction and maintenance needs a large amount of duration, can not adapt to the hair of current green building Exhibition.Based on this, the invention proposes light steel pipe-timber with small diameter combination load-bearing pillars that a kind of band divides chamber steel plate, and core is that band divides chamber The light steel tube of steel plate, steel duct pour timber with small diameter sawdust filler, and timber with small diameter, periphery packet are filled in point cavity space gap Wrapping up in FPR carbon cloth, corner is reinforced using angle steel simultaneously, and compared to traditional concrete bearing column, bearing capacity is significantly mentioned Height reduces template construction, while sufficiently having developed and utilized timber with small diameter, meets the development need of current green building, fits Development for low multilayer country building.
Summary of the invention
The purpose of the present invention is to provide it is a kind of have many advantages, such as stress science, simple structure and it is environmentally protective integration Band divides light steel pipe-timber with small diameter combination load-bearing pillar of chamber steel plate, bad to effectively solve conventional concrete column bearing capacity, applies The problems such as work low efficiency, resource utilization is low.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of band divides light steel pipe-timber with small diameter combination load-bearing pillar of chamber steel plate, which includes sawdust mixture 1, light steel tube 2, timber with small diameter 3, divide chamber steel plate 4, FRP carbon cloth 5 and Conner reinforcement 6;Light steel tube 2 is arranged in the group The centre of load-bearing pillar is closed, light steel tube 2 is the central cavity structure of the combination load-bearing pillar, the outer surface welding of central cavity structure Have it is several be equidistantly evenly arranged divide chamber steel plate 4, light steel tube 2 and collectively constitute the combination load-bearing after dividing chamber steel plate 4 to weld Column forms core reinforcing bar, and FRP carbon cloth 5 is wrapped in a point outside for chamber steel plate 4, each point of chamber steel plate 4 and FRP carbon cloth 5 Between formed outer portion cavity configuration, periphery package FRP carbon cloth 5 be capable of providing good core effect of contraction;Light steel tube 2 Inside poured sawdust mixture 1, to improve the stress performance of core reinforcing bar;Path is placed in filling in outer portion cavity configuration Timber 3;The corner location of FRP carbon cloth 5 is equipped with Conner reinforcement 6 to provide additional confining guard;
Sawdust mixture 1 is made of sawdust, latex, fine sand, cement and water, and sawdust is when timber with small diameter 3 is pre-machined Product, sawdust, latex, fine sand, cement, water carry out uniform mix, the particle diameter of fine sand according to 1:1:0.25:0.25:0.05 For 5mm-10mm, filling work should be completed after the uniform mix of sawdust, latex, fine sand, cement, water before initial set;Sawdust simultaneously It can be replaced with waste straw, Replacement rate is 0~100%, and waste straw is processed into 10mm or less size.
The light steel tube 2 is one of core reinforcing bar component part, and light steel tube 2 is collectively constituted with the welding of chamber steel plate 4 is divided Core reinforcing bar.The section of light steel tube 2 is round or rectangle, it is contemplated that construction in later period is convenient, it is proposed that uses rectangular in form, steel Tube thickness is not more than 4mm, and outer diameter of steel pipes should not exceed 200mm.
The timber with small diameter 3 is the timber that diameter outside bark is 40mm~80mm, and timber with small diameter 1, which is processed into section, in advance is Rectangle, convenient for making full use of for timber with small diameter, the size dimension of rectangle is the multiple of 20mm, such as 20mm × 40mm, 40mm × 40mm, 40mm × 20mm, 20mm × 20mm, timber with small diameter 3 is in dividing cavity region in layering interlaced arrangement;Each layer timber with small diameter 3 And it is bonded between each timber with small diameter 3 by latex.
Described point of chamber steel plate 4 is one of core reinforcing bar component part, divides chamber steel plate 4 to weld with light steel tube 2 and collectively constitutes Core reinforcing bar.Point chamber steel plate 4 is made using sheet metal, and steel plate thickness is preferably 2~3mm, divide 4 strength of parent of chamber steel plate preferably with 2 steel plate mother metal intensity of light steel tube is consistent.
The FRP carbon cloth 5 is woven by 12K carbon fiber wire, and FRP carbon cloth 5 is wrapped in structure outermost layer, with Improve the effect of contraction to internal structure.Bonding the number of plies is preferably 2~3 layers, and every layer of FRP carbon cloth 5 need to be overlapped when pasting, The lap of splice is not less than 150mm, and the additional brushing primer of overlapping regions, prevents overlapping regions from unclamping.
The Conner reinforcement 6 is the corner protector measure of structure, while providing and acting on internal structure additional restraint.Angle Portion's reinforcer 6 is angle steel, and angle steel is having a size of 30mm*30mm*4mm, and angle steel strength of parent is consistent with internal reinforcing bar intensity, and corner adds Strong part 6 reserves rivet hole, convenient and 3 rivet interlacement of timber with small diameter.
A kind of band divides light steel pipe-timber with small diameter combination load-bearing pillar of chamber steel plate, the production method is as follows:
