The L-shaped section light steel-small diameter wood combined bearing column is applicable to a new system of a low multi-layered construction structure; a profile steel framework is arranged inside the bearing beam, and the bearing capability of the structure is improved by about 20% due to the enclosure protection function of small-diameter wood; the light steel and the small-diameter wood are subjected to superior combination, so that the overall dead weight of the structure is greatly reduced, the anti-earthquake performance of the structure is improved by about 25%; the small-diameter wood is better utilized and developed, so that the project cost is reduced by 15%, and the environment protection and low carbon are truly achieved.
Description
Technical field
The present invention relates to the light steel in a kind of L shaped cross 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 is high and easy industrialization is produced, and has been used in a large number various building fields.
Continuous scarcity along with 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, has also solved 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 a kind of simple to operate, be easy to construction, core is type steel skeleton, timber with small diameter take around as filler, and 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 in L shaped cross 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 in a kind of L shaped cross section-timber with small diameter combination load-bearing pillar and the practice, the light steel in a kind of L shaped cross section of the present invention-timber with small diameter combination load-bearing pillar, this L shaped load-bearing pillar comprises timber with small diameter 1, channel-section steel 2, angle steel 3, adhesive glue 4, toe joint plate 5.
Particularly, 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 L shaped timber, and size is less than 50mm, between timber with small diameter, by latex, bonds.
Channel-section steel 2 is one of inside configuration cage of reinforcement, has replaced the inner reinforcing bar of conventional steel reinforced concrete, mainly provides end strengthening to fix and effect of contraction, can adopt medium-sized equal leg angle to be welded, and the equal leg angle of selecting is of a size of 80mm～125mm.
Angle steel 3 is one of inside configuration cage of reinforcement, has replaced the inner reinforcing bar of conventional concrete, mainly plays the effect of center framework, can adopt medium equal leg angle, and size is selected as required, and general size is 80mm～125mm.
Adhesive glue 4 is mainly between toe joint plate 4 flexible adhesion is provided, and can carry out rational proportion by white glue with vinyl and wood binder and form, and can to bonding position, scrape hair in advance and process before smearing, and to improve bond effect, the thickness of smearing is no more than 5mm.
Toe joint plate 5 is outer peripheral protection structure, and the thickness of employing should not surpass 25mm, and toe joint plate preferably selects dark tooth to connect, so that the later stage is brushed outside coating, is beneficial to overall appearance.
The light steel in L shaped cross section-timber with small diameter combination load-bearing pillar, its preparation method is as follows.
The first step, the vertical core angle steel of location frame and end channel-section steel, wherein weld with grade beam reinforcing bar angle steel and channel-section steel bottom.
Second step, pre-determines the position of pillar frame, fills the small dimension wood of prior preparatory processing in core angle steel, channel-section steel and column frame space, and wherein small dimension wood bonds fixing 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 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.
Below be only a typical case study on implementation of the present invention, enforcement of the present invention is not limited to this.
The light steel in the L shaped cross 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 alleviated the integral body 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).
