Abstract
The utility model belongs to the technical field of building structure, concretely relates to connected node of roof beam and post in light-duty timber structure. In the utility model, the connection of the wood beam and the wood column is pin connection; the first steel plate is connected with the wooden beam through a first bolt, and belongs to double-shear connection in pin connection; the second steel plate is connected with the wooden column through a second bolt, and belongs to single shear connection in pin connection; a supporting plate is welded at the bottom of the first steel plate and the second steel plate; the lower part of the wood beam is planed, and the wood beam is tightly attached to the supporting plate. The original wood beam and wood column connecting node and the pin groove pressure-bearing checking calculation generally do not meet the standard requirements. The utility model discloses a wood beam post connected node structure can reduce connecting bolt's atress greatly to avoid this connected node to appear surrendering mode I shown surrendering, improve the degree of safety of nodal connection, and convenient construction.
Description
Technical Field
The utility model belongs to the technical field of building structure, concretely relates to light-duty timber structure connected node.
Background
In the current building timber structures such as houses and the like, the connecting joint of a beam and a column has the advantages of simpler structure, unbalanced stress, and potential safety hazard, and the pin groove bearing check calculation of the connecting joint generally does not meet the standard requirement.
Disclosure of Invention
An object of the utility model is to provide a high, simple structure's light-duty timber structure middle beam and the connected node structure of post of security.
The utility model discloses a connected node structure of roof beam and post in light-duty timber structure improves the connected node of current roof beam and post, specifically is that the steel sheet lower part in former connected node increases a layer board to reduce connecting bolt's atress, thereby avoid this connected node to appear surrendering mode I shows surrender, improve the degree of safety of nodal connection.
The utility model relates to a light-duty timber structure center sill and the connected node of post, its structure is shown in figure 1, figure 2. The wood beam and the wood column are connected by a pin. The first steel plate 3 is connected with the wood beam 1 through a first bolt 5, and belongs to double shear connection in pin connection; the second steel plate 4 is connected with the wooden column 2 through a second bolt 6, and belongs to single shear connection in pin connection; in the pin joint, the pin groove pressure-bearing failure has four failure modes, wherein in a yield mode I, the design standard of the wood structure has the following regulations: in the case of a single shear connection, the requirement (R) e R t Less than or equal to 1.0); in the case of double shear connection, the requirement (R) e R t Less than or equal to 2.0). Through statistics, in the pin connecting node calculation results of most of the wood beams and the wood columns, the value in the yield mode I does not meet the standard requirement, namely, the pin slot pressure bearing does not meet the standard requirement. In order to solve the problem, a supporting plate 7 is additionally welded at the bottom of the first steel plate 3 and the second steel plate 4, the lower part of the wood beam 1 is planed, and the wood beam 1 is tightly attached to the supporting plate 7.
During construction, the supporting plate 7 can be used as a temporary support; after the connecting bolt is installed in place, the supporting plate 7 can be divided into partial shearing forces, and the risk of pressure bearing damage of the pin groove in double-shear connection is reduced.
The utility model discloses in, first bolt 5, second bolt 6 are connecting bolt, and the diameter is generally not less than 12, specifically confirms according to the calculation.
In the utility model, the supporting plate 7 is a steel plate with the size of (80 to 100mm) multiplied by the beam width and the thickness of 10 to 12mm.
The pressure-bearing checking calculation of the pin grooves of the connecting joints of the log beams and the wood columns generally does not meet the standard requirements. The utility model discloses a timber beams post connected node structure can reduce connecting bolt's atress greatly to avoid this connected node to appear surrendering mode I shown surrendering, improve the degree of safety of nodal connection, and convenient construction.

Fig. 1 is the utility model discloses wood beam post connected node elevation.
Fig. 2 is the utility model discloses wood beam wood column connected node top view.
Reference numbers in the figures: 1 is the timber beams, 2 is the timber columns, 3 is the first steel sheet of being connected with the timber beams, 4 is the second steel sheet of being connected with the timber beams, 5 is the first (kind) bolt of being connected with the timber beams, 6 is the second (kind) bolt of being connected with the timber columns, 7 is the layer board.
Detailed Description
If the supporting plate 7 is not provided, the wood beam 1 is connected with the first steel plate 3 by virtue of the first bolt 5, and the first bolt 5 is subjected to double-sided shear resistance and is a main stress component. The supporting plate 7 is added and is planed and tightly propped against the bottom plate of the wood beam 1, and then the vertical force is preferentially transmitted to the supporting plate 7. The shearing force borne by the first bolt 5 is reduced, so that the pin groove bearing is reduced, and the pin groove bearing damage can be avoided.
While, for purposes of simplicity of explanation, the methodologies are shown and described as a series of structures, it is to be understood and appreciated that the methodologies are not limited by detail, as some structures may, in accordance with one or more embodiments, occur in different orders and/or concurrently with other actions from that shown and described herein or not shown and described herein, which may be understood by those skilled in the art.
The previous description of the disclosure is provided to enable any person skilled in the art to make or use the disclosure. Various modifications to the disclosure will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other variations without departing from the spirit or scope of the disclosure. Thus, the disclosure is not intended to be limited to the examples and designs described herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
