Description

A reinforced beam-column joint of assembled timber frame structure

technical field

The utility model relates to an assembled beam-column joint of a wooden frame structure, which is mainly used in low-rise wooden frame structures in the construction field.

Background technique

Because wood has the advantages of easy material acquisition, easy processing, light weight, easy transportation, assembly and disassembly, and multiple uses, it is widely used in house construction. Compared with most steel structure and masonry structure systems, the construction cost of wood structure buildings is low, and it can be constructed on site, componentized or prefabricated. It can withstand wind load and snow load, and its anti-seismic performance is superior to that of masonry structures. Therefore, it is particularly suitable for low-rise family housing, row houses or multi-family housing in a group manner, and other housing buildings below three floors.

The traditional wooden structure buildings in my country are log structures, and the beams and columns are connected by mortise and tenon joints, which weakens the firmness of wooden components, low connection strength, poor ductility, and low utilization rate of wood. The wall bearing system of densely rowed keels and high-strength panels used in North American light wood structures consumes a lot of wood and is expensive, which is not suitable for the construction of rural houses in my country. Therefore, the prefabricated wood frame structure is more in line with the requirements of building industrialization and energy saving and environmental protection.

At present, the research and application of prefabricated wood frame structures are very limited, and the joint forms of wood frame structures are even rarer. It is urgent to propose a beam-column joint connection form of wood frame that is simple to manufacture, convenient to construct, and clearly stressed, so as to promote the application of prefabricated wood frame structures.

detailed description

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Figures 1 to 3, a beam-column joint of a reinforced assembled wood frame structure, including a wooden beam 4, a wooden column 3, a U-shaped connector 2 and a reinforced corner piece 1; at the end of the wooden beam 4 There is a transverse intermediate recess 4-1 extending along its entire height and two vertical slots 4-2, and the two vertical slots 4-2 are symmetrically arranged in the transverse intermediate recess 4- 1; the end of the wooden beam 4 is connected to the wooden column 3 through a U-shaped connector 2 and two reinforced corners 1, and the side plates of the U-shaped connector 4 are vertical set and its height is equal to the height of the wooden beam 4, the bottom plate of the U-shaped connector 2 is fixed on the wooden column 3 with bolts I, and the two side plates of the U-shaped connector 2 are respectively inserted into Installed in the two vertical slots, the U-shaped connector 2 and the end of the wooden beam 4 are connected together by bolt II5; Reinforced corner fittings 1, the two reinforced corner fittings 1 located on the upper and lower sides of the wooden beam 4 and the wooden beam 4 are connected together by bolts III, and the reinforced corner fittings located on the upper side of the wooden beam 4 1 and the wooden column 3 are connected together by bolt IV, and the reinforcing corner piece 1 located on the lower side of the wooden beam 4 is connected with the wooden column 3 by bolt V.

The above-mentioned wooden beams 4 and wooden columns 3 can be made of glued wood or square wood, which are directly prefabricated in the factory. The U-shaped connecting piece 2 and the reinforced corner piece 1 can be made of steel or aluminum alloy.

During the prefabrication process of wooden beam 4, wooden column 3, U-shaped connector 2 and reinforced corner piece 1, bolt holes should be opened at the bolt joints, and the diameter of the bolt holes should be 1 to 2 mm larger than the diameter of the bolt screw. The wooden beam 4 should be pre-grooved at the insertion place of the U-shaped connector 2, and the groove width should be 1-2 mm larger than the thickness of the U-shaped connector. The thickness of the wood at the end of the beam after the slotting of the wooden beam 4 should meet the requirements of the minimum thickness of wood in the "Code for Design of Timber Structures". In order to control the gap between the end of the wooden beam 4 and the wooden column 3, the recessed depth of the end of the wooden beam 4 should be slightly greater than the extension length of the bolt I.

When the reinforced corner piece 1 and the U-shaped connector 2 are made of steel, the spacing of bolts Ⅰ, Ⅱ5, Ⅲ, Ⅳ and Ⅴ shall meet the minimum bolts specified in the "Code for Design of Timber Structures".
