Description

The light steel of T section-timber with small diameter combination load-bearing pillar and preparation method
Technical field
The present invention relates to the light steel of a kind of T section-timber with small diameter combination load-bearing pillar and preparation method, belong to technical field of structural engineering.
Background technology
Along with the fast development of China's dwelling construction, for meeting the growing housing need of the people, advance modernization of the housing industry, No. 72 file of State Council " 1999 " clearly proposes: development steel house, the occupation rate of market of expansion steel house.And lightweight steel construction is the important component part of steel work, its importance is self-evident, specifically can comprise angle steel, steel pipe, channel-section steel and Light-weight Gabled Frames etc., due to lightweight steel construction from heavy and light, rigidity high and easy industrialization produce, be used in a large number various building fields.
Along with the continuous scarcity of resource, the timber resources of China is also faced with severe problem, because majority state should be through embargo virgin wood, therefore rely on imported timber to become impossible, simultaneously, in use, due to the favor to major diameter timber, cause the timber of minor diameter seldom by complete exploitation and use, most timber with small diameter are by serious waste.The timber with small diameter how complete development and utilization is ignored by people has become studying a question of current focus, and the solution of this problem not only will be alleviated crisis of resource effectively, also solve to a certain extent forest reserves imbalance between supply and demand.
Although traditional wooden construction anti-seismic performance is good, cost is lower, but supporting capacity relative deficiency, and although traditional steel work anti-seismic performance and supporting capacity are better, but cost is comparatively expensive, be difficult to extensive use, so the two is carried out to rational advantage combination, form a kind of new composite structure, become starting point of the present invention.Based on this, the present invention proposes one simple to operate, be easy to construction, core is type steel skeleton, around, taking timber with small diameter as filler, outermost layer is pasted toe joint plate, than traditional wooden construction, its bearing capacity and anti-seismic performance effectively improve, and more cheap for its cost of conventional steel structure, meanwhile, take full advantage of timber with small diameter, turn waste into wealth and really accomplish green low-carbon environment-friendly, be highly suitable for low, multilayer villages and small towns architectural structure system.
Summary of the invention
The object of the present invention is to provide a kind of light steel of T section-timber with small diameter combination load-bearing pillar with advantages such as simple structure, cheap, easy construction, green low-carbon environment-friendly are integrated, general to effectively solving conventional concrete post supporting capacity, poor seismic behavior, cost is high, cannot accomplish the problems such as environmental protection.
For achieving the above object, the technical solution used in the present invention is the light steel of a kind of T section-timber with small diameter combination load-bearing pillar and the practice, and concrete technical scheme is as follows:
The light steel in a kind of L shaped cross section-timber with small diameter combination load-bearing pillar, it comprises timber with small diameter 1, channel-section steel 2, angle steel 3, adhesive glue 4, toe joint plate 5; Load-bearing pillar inside is taking channel-section steel 2 and angle steel 3 as L shaped cage of reinforcement, and wherein channel-section steel 2 is arranged in two L shaped acras, and angle steel 3 is arranged in L shaped corner; L shaped cage of reinforcement is filled timber with small diameter 1 around, mentions and fishplate bar 5 wherein, between toe joint plate, bonds by adhesive glue 4 in the outermost subsides of load-bearing pillar, forms the light steel in L shaped cross section-timber with small diameter combination load-bearing pillar.
Described timber with small diameter 1 is the small wood of diameter outside bark below 60mm, for the ease of making full use of of small dimension wood, in advance small dimension wood is processed into rectangular timber, and the length of side is less than 50mm, between timber with small diameter, bonds by latex.
Described channel-section steel 2 is one of inside configuration cage of reinforcement, adopts medium-sized equal leg angle to be welded, and the equal leg angle length of side of selecting is 80mm~125mm, and thickness is 8mm~12mm.
Described angle steel 3 is that one of inside configuration cage of reinforcement adopts medium equal leg angle, and the equal leg angle length of side of selecting is 80mm~125mm, and thickness is 8mm~12mm.
Described adhesive glue 4, for providing flexible adhesion between toe joint plate 5, is carried out proportioning by white glue with vinyl and wood binder and is formed, and can scrape hair to bonding position in advance and process before smearing, and to improve bond effect, the thickness of smearing is no more than 5mm.
Described toe joint plate 5 is outer peripheral protection structure, and the thickness of employing should not exceed 25mm; Described toe joint plate 5 selects dark tooth to connect, so that the later stage is brushed outside coating, is beneficial to overall appearance.
The preparation method of the light steel in described L shaped cross section-timber with small diameter combination load-bearing pillar, making step is as follows:
The first step, core angle steel 3 and L shaped two end channel-section steels 2 of location Jia LiLXing corner, wherein angle steel 3 and channel-section steel 2 bottoms and grade beam reinforcing bar weld.
Second step, pre-determines the position of pillar frame, fills the timber with small diameter 1 of prior preparatory processing in described angle steel 3, channel-section steel 2 and column frame space, and wherein small dimension wood bond and fixed by latex;
The 3rd step, throws flat processing and brushing twice white glue with vinyl to most external small dimension wood surface;
The 4th step, pastes toe joint plate 5 to be hung on outermost layer small dimension wood surface, and the toe joint plate of corner bonds by adhesive glue, has just formed the light steel in L shaped cross section-timber with small diameter combination load-bearing pillar.
The light steel of T section of the present invention-timber with small diameter combination load-bearing pillar is applicable to low, multilayer novel building system.Inside is provided with type steel skeleton, and due to the effect of going along with sb. to guard him of timber with small diameter, the supporting capacity of structure is improved, and is about 20%; By light steel-timber with small diameter is carried out to advantage combination, greatly alleviate the entirety deadweight of structure, anti-seismic performance 25% left and right that can improve structure, simultaneously, fully development and utilization timber with small diameter, well solved the waste problem of timber with small diameter, really accomplished environmental protection low-carbon (LC).
