Abstract

The utility model relates to a wood structure building post and post connected node structure, its middle standing pillar and stand are connected by the steel connecting piece, the steel connecting piece comprises square steel sheet and 4 root circle reinforcing bar vertical welding, respectively there are 4 circular embeddings mouths at the both ends of stand, glue with the engineering between stand and the steel connecting piece and reinforce, the utility model discloses glue the connection that replaces tenon fourth of the twelve earthly branches realization wood structure building post and post with steel connecting piece and engineering, joint strength, the bending resistance of node improve than mortise -tenon joint by a wide margin, are particularly useful for large -scale timber structure and connect, node simple structure, component easily realize mechanized production, the node simple installation, construction speed is fast, and the cost of manufacture is low.

Description

A kind of timber buildings post and column jointing gusset structure

Technical field

The utility model relates to building structure technology field, particularly a kind of timber buildings post and column jointing gusset 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 current wooden construction also exists very large defect in the connection of post and post, 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 post and column jointing gusset 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 post that the utility model provides and column jointing gusset structure, comprise at least two root posts and steel connector, wherein steel connector comprises square steel sheet and four round bars, four round bars and square steel sheet vertical welding, connected by steel connector between column.

The two ends of described column respectively have four circles corresponding with round bar to embed mouth; The end of described column embeds in described round bar.

The available engineering glue of connection between described column and steel connector is reinforced.

The described thick 0.2cm of square steel sheet, the upper and lower length of round bar is respectively 20cm.

The beneficial effects of the utility model are: compared with mortise-tenon joint, and the utility model possesses following advantage,

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

2, the utility model column jointing gusset 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.

Accompanying drawing explanation

Accompanying drawing is the utility model embodiment---the schematic diagram of two root post connected nodes, wherein:

Fig. 1 is the 3 D stereo schematic diagram of the utility model 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 Fig. 1 central post;

In figure: 1 square steel sheet, 2 round bars, 3 columns, 4 circular embedding mouths.

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 two root posts in timber buildings.

As shown in Figure 1, two root posts 3 of this node are linked into an integrated entity by a steel connector.

This steel connector as shown in Figure 2, is made up of a square steel sheet 1 and four round bar 2 vertical weldings.Wherein square steel sheet size is identical with the appearance and size of column, and the size of circular embedding mouth 4 is also identical with the appearance and size of round bar.

As shown in Figure 3, the upper and lower end parts of column respectively has 4 circular embedding mouths.

During installation, first with engineering glue, the external surface of steel connector is filled, then 4 of steel connector round bars 2 are inserted the corresponding circular embedding mouth 4 in column 3 upper end fixed, then the circle of another root post lower end is embedded the round bar that mouth aims at corresponding steel connector, last compacting completes the docking of two root posts.

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