Description

A kind of timber buildings beam-column connection structure
Technical field
The present invention relates to building structure, particularly a kind of timber buildings beam-column connection structure.
Background technology
Timber buildings are widely used all over the world, both can single household, the apartment at many families of multilayer can be formed again Building.Some low layer commercial buildings and public building, such as restaurant, school, church, shop and office building also use this structure System.
Compared with Reinforced Concrete & Brick Structure is built, wooden frame structure has service life length, constructed the simple, duration The advantages of short, personalizable indoor design, high insulating effect, good permeability, antidetonation, although build the wood used in wooden frame structure Material material cost is higher than concrete and masonry building, but because workmen is few, short construction period, cost of labor be low, dress Repair that expense is low, so the overall cost in house is high unlike concrete and masonry structure room.
Just because of above feature, timber buildings are widely used by Asian countries such as Japan, South Korea.Chinese is upper Sea, Beijing, Shenzhen, Dalian, Suzhou, Hangzhou, Wuhan, Ningbo, Shenyang, Chengdu etc. area also occurred this wooden house, Villa and apartment.
It is well known that timber structure, which is built, mostly uses traditional mortise-tenon joint technology, mortise-tenon joint no doubt has many good qualities, But in terms of modern industry angle, joinery and its construction also has many shortcomings.One is because most of Tenon is difficult with automated machine Equipment is molded, and achieves mechanization production difficulty big;Two be the skilled timber skilled worker of most of Tenon making needs, and China Present this kind of skilled worker is seldom, and which adds construction cost;Three be that Tenon overlap joint rigidity is relatively low, because timber is disconnected The loss in face, causes mechanical properties decrease at node, it is difficult to undertake large-scale timber structure connection.
The content of the invention
The disadvantages mentioned above of mortise-tenon joint is built for timber structure, it is an object of the invention to provide a kind of simple in construction, node Intensity height, simple installation, the timber buildings beam-column connection structure of low manufacture cost.
To achieve the above object, the timber buildings beam-column connection structure that the present invention is provided, including wooden frame and pin; Wooden frame and pin are connected by steel connector;The steel connector by square sleeve and at least one hung down with square sleeve side wall Straight integrally welded " u "-shaped groove is constituted;The end of the wooden frame is embedded in the " u "-shaped groove, and by bolt by wooden frame and " U " Shape groove is fixedly connected;The end of the pin is inserted in the square sleeve, and pin and square sleeve are fixed into company by bolt Connect.
To improve the bending resistance of node, steel inverted " u " is installed with described be fixedly connected on the bolt of wooden frame and " u "-shaped groove Shape clip, the upper surface of the wooden frame beyond " u "-shaped groove cell wall (thickness of wooden frame is more than the depth of " u "-shaped groove), beyond There is neck at the position of the wooden frame top correspondence inverted " u "-shaped clip of " u "-shaped groove cell wall, and the inverted " u "-shaped clip is embedded in the card In groove.
Compared with mortise-tenon joint, it is an advantage of the invention that:
1st, the present invention replaces Tenon to realize the connection of timber buildings beam and column with steel connector and bolt and clip, saves Bonding strength, bending resistance and the tensile capacity ratio mortise-tenon joint of point are increased substantially, and the large-scale timber structure that is particularly suitable for use in connects Connect.
2nd, beam-column connection of the present invention is simple in construction, and component easily realizes mechanization production.
3rd, node installation is easy, and to installation personnel without particular/special requirement, speed of application is fast.
4th, node cost of manufacture is lower than mortise-tenon joint.
Brief description of the drawings
Accompanying drawing is the embodiment of the present invention --- two wooden frames and the schematic diagram of a column connecting node, wherein:
Fig. 1 is the 3 D stereo schematic diagram of node;
Fig. 2 is the 3 D stereo schematic diagram of steel fastener in Fig. 1;
Fig. 3 is the 3 D stereo schematic diagram of inverted " u "-shaped clip in Fig. 1;
Fig. 4 is the 3 D stereo schematic diagram of wooden frame in Fig. 1.
In figure:1- pins, 2- square sleeves, 3- wooden frames, 4- " u "-shaped grooves, 5- inverted " u "-shaped clips, 6- bolts, 7- necks, 8- bolt mounting holes.
Embodiment
Below in conjunction with drawings and examples, the present invention will be further described.
The present embodiment is the connecting node being made up of two wooden frames and a root post using the present invention in timber buildings.
As shown in figure 1, two wooden frames 3 and a pin 1 of the node are linked into an integrated entity by a steel connector.
The steel connector is as shown in Fig. 2 by a square sleeve 2 and two and square sleeve upper portion side wall vertical welding Integral " u "-shaped groove 4 is constituted.Wherein the cylinder inside dimension of square sleeve is identical with the appearance and size of pin, the groove width of " u "-shaped groove Identical with the width of wooden frame, the depth of " u "-shaped groove is less than the thickness of wooden frame, the upper surface of wooden frame is higher by the cell wall of " u "-shaped groove (being higher by size identical with the steel plate thickness of following inverted " u "-shaped clips);On two corresponding barrels of square sleeve and " u "-shaped Laterally corresponded to respectively on two cell walls of groove and open up two bolt mounting holes 8.
As shown in figure 3, making four and the matching used inverted " u "-shaped clip 5 of above-mentioned steel connector with bar steel plate. Width on the inside of " u "-shaped clip is identical with two cell wall outside widths of the " u "-shaped groove, inverted " u "-shaped clip is held in " U " The cell wall lateral surface of shape groove, also being opened up respectively on the two side of inverted " u "-shaped clip can install with the bolt on " u "-shaped groove cell wall The bolt mounting holes 8 of hole docking.
Opened up respectively and the bolt mounting holes on the square sleeve and " u "-shaped groove in the upper end of pin and the front end of wooden frame The relative bolt mounting holes 8 connect, the inverted " u "-shaped clip can be inlayed by laterally being opened up in top its bolt mounting holes of correspondence of wooden frame Neck 7, neck depth is identical with the steel plate thickness of inverted " u "-shaped clip.
During installation, the upper end of pin is inserted in square sleeve, it is default by square sleeve and pin upper end with bolt 6 Pin and square sleeve are fastened together by bolt mounting holes;The front end of two wooden frames is respectively embedded into two " u "-shaped grooves again, Four inverted " u "-shaped clips are respectively embedded into the neck on two wooden frames, clip, " u "-shaped groove cell wall and wooden frame are passed through with bolt Default bolt mounting holes, wooden frame, " u "-shaped groove and clip are fastened together.
It should be noted that the present embodiment is mainly used in understanding the present invention, protection scope of the present invention is not limited to the implementation Example, the timber buildings four direction of every use technical solution of the present invention composition, five directions, the nodes connections of six direction (connecting node being made up of many pins and wooden frame), within protection scope of the present invention.
