Description

A kind of timber buildings beam-column connection structure

Technical field

The utility model relates to building structure, particularly a kind of timber buildings beam-column connection structure.

Background technology

Timber buildings is widely used all over the world, both can single household, can form again the block of flats at the many families of multilayer.Some low layer commercial building and public buildings, as restaurant, school, church, shop and office building etc. also adopt this structural system.

Compared with building with Reinforced Concrete & Brick Structure, wooden frame structure has long service life, simple and easy, the advantage such as the duration is short, personalizable interior design, high insulating effect, good permeability, antidetonation of constructing, although build wooden frame structure wooden material cost used higher than concrete and masonry building, but because constructor is few, short construction period, cost of labor are low, decoration cost is low, thus the overall cost in house unlike concrete and masonry structure room high.

Just because of above feature, timber buildings is widely adopted by Asian countries such as Japan, Korea S.Also there is this wooden house, villa and apartment in the area such as Shanghai, Beijing, Shenzhen, Dalian, Suzhou, Hangzhou, Wuhan, Ningbo, Shenyang, Chengdu of China.

As everyone knows, wooden construction is built and is mostly adopted traditional mortise-tenon joint technology, and mortise-tenon joint no doubt has many good qualities, but from modern industry angle, joinery and its construction also has many shortcomings.One is because most of Tenon is difficult to utilize automated machine equipment shaping, achieves mechanization production difficulty large; Two is that most of Tenon makes the skilled timber skilled worker of needs, and the present this kind of skilled worker of China seldom, which adds construction cost; Three is that Tenon overlap joint rigidity is lower, due to the loss of timber section, causes Nodes mechanical properties decrease, is difficult to bear large-scale wooden construction and connects; Four is that current wooden construction also exists very large defect in the connection of beam column, so can only build the wood structure building of low layer, high-rise wood structure building is also difficult to realize.

Summary of the invention

Build the above-mentioned shortcoming of mortise-tenon joint for wooden construction, the purpose of this utility model is to provide the timber buildings beam-column connection structure that a kind of structure is simple, node strength is high, simple installation, cost of manufacture are low.

For achieving the above object, the timber buildings beam-column connection structure that the utility model provides, comprise wooden frame, pin and steel connector, wherein wooden frame is connected by steel connector with pin;

Described steel connector comprises cross steel sheet and 4 blocks of in-line steel sheets, and in-line steel sheet is positioned at cross steel-sheet end, integrally forms with cross steel sheet; Wooden frame and pin are connected by being plugged on cross steel sheet and 4 blocks of in-line steel sheets.

Respectively there are two vertical in-line filletings and three horizontal steel bar fixing ports in the two ends of described wooden frame, and size and the in-line steel-sheet of in-line filleting are measure-alike; Respectively there are two cross filletings the end of described pin, and size and the cross steel-sheet of cross filleting are measure-alike; Described cross steel-sheet two block plate is mutually vertical, and size is identical with the width of pin; Described in-line steel-sheet vertical array has 3 steel bar fixing ports, and in-line steel-sheet width is identical with the width of wooden frame; The length of described fixing steel bar is slightly larger than the width of wooden frame, and attaching nut tightens reinforcing.

Compared with mortise-tenon joint, the utility model has the advantages that:

1, the utility model steel connector replaces Tenon to realize connecting of timber buildings beam column, and the bonding strength of node, bending resistance and resistance to tension all increase substantially than mortise-tenon joint, are particularly useful for the connection of large-scale high-rise timber buildings beam column.

2, the utility model beam-column connection structure is simple, and component easily realizes mechanization production.

3, node installation is easy, and to installation personnel without particular/special requirement, speed of application is fast.

4, the cost of manufacture of node is lower than mortise-tenon joint.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described further.

The present embodiment is the connected node adopting the utility model to form by wooden frame and pin in timber buildings.

As shown in Figure 1, two pins 4 of this node and 4 wooden frames 6 are linked into an integrated entity by a steel connector.

This steel connector as shown in Figure 2, is made up of the steel sheet vertical welding of two pieces of given configuration.This steel connector can be divided into two parts by using function, be respectively cross steel sheet 1 part and in-line steel sheet 2 part, wherein in-line steel sheet also has three vertically disposed steel bar fixing ports 3, and two-part steel-sheet width is all identical with the width of pin with corresponding wooden frame.

As shown in Figure 3, the upper and lower end parts of pin respectively has 2 cross filletings 5, and the size of filleting is just identical with cross steel-sheet appearance and size.

As shown in Figure 4, respectively there are 2 in-line filletings 7 at the two ends, left and right of wooden frame, and the size of filleting is just identical with in-line steel-sheet appearance and size.With the face of filleting plane orthogonal on also vertical array three steel bar fixing ports.

During installation, first with engineering glue, the cross steel sheet external surface of steel connector is filled, then the latter half cross steel sheet of steel connector is inserted the corresponding cross filleting 5 in pin 4 upper end fixed, then the cross filleting mouth 5 of another root pin 4 lower end is aimed at the first half cross steel sheet 1 of corresponding steel connector, then compacting completes the docking of two pins 4.Then the in-line filleting 7 of wooden frame is aimed at in-line steel sheet 2 to insert, steel bar fixing port 9 on in-line filleting is fitted like a glove with the steel bar fixing port 3 on in-line steel sheet, then fixing steel bar 8 is passed wooden frame, in-line steel sheet 2 successively, nut of finally screwing on completes the installation of wooden frame.The installation steps of other wooden frames are also like this.

It should be noted that, be preferably coated with thicker during brushing engineering glue, engineering glue can be made like this to fill up gap between steel connector and pin filleting mouth, thus improve bonding strength.

It should be noted that; the present embodiment is mainly used in understanding the utility model; protection domain of the present utility model is not limited to this embodiment; the node in a direction of the timber buildings wooden frame that every employing technical solutions of the utility model are formed, both direction, three directions connects (connected node be namely made up of two pins and a wooden frame or two wooden frames or three wooden frames), all within protection domain of the present utility model.
