Description

Ancient building roof structure

technical field

The utility model belongs to the construction field and relates to an ancient building eaves structure.

Background technique

At present, in the antique buildings, the main skeleton of the building is still a concrete structure. For some antique buildings, the requirements for local timber structures, especially the eaves, are extremely strict, resulting in the limited size of the structural components, which is not easy to realize. For example: the outer corridor of Tang’s ancient building has a wooden suspended ceiling with bucket arches on the top of the columns. At the same time, the width of the corridor is relatively large, and the size of the columns on the outside of the corridor is small, which does not meet the requirements of the relevant concrete specifications for column size. In addition, the space above the wooden part of the antique building is limited, and the concrete structure is not easy to realize.

Utility model content

In view of the above problems, the utility model provides a stable, economical and applicable ancient building eave structure.

The technical scheme of the utility model is to provide an ancient building eaves structure, which includes a frame column and a main beam erected on the frame column, a secondary beam horizontally arranged on the main beam, and the main beam and the secondary beam There are also oblique beams extending obliquely to the outside and below to form the eave structure. on the beam.

Preferably, the main beam includes an upper beam and a lower beam parallel to each other, a filling wall is arranged between the upper beam and the lower beam, and the diagonal brace is arranged between the lower beam and the inclined beam.

Preferably, a diagonal brace is provided at a position corresponding to each of the secondary beams.

Preferably, the connection between the filling wall and the diagonal brace adopts a full-beam stirrup encryption structure.

Preferably, the connection between the main girder and the diagonal bracing adopts a longitudinal reinforcement or a stirrup diameter plus one grade.

Preferably, the inclined beam adopts a tension-bend member.

Preferably, the braces are all compression and bending members.

The ancient building eaves structure of the utility model introduces the concept that triangles have stability in mathematics, and adds diagonal braces to the roof system, so that the inclined beams and diagonal braces form a simple force-bearing system, which can solve the limited space above the wooden structure in the antique buildings , the problem that the concrete structure is not easy to realize, also realizes the effect of reasonable force transmission on the structure. It also has the following beneficial effects: direct and reliable force transmission: the surface load is transmitted to the beam through the plate, and then transmitted to the column through the beam and the diagonal brace, fully realizing the performance of the reinforced concrete material; the structure is simple: in the antique building, there are often appearances on the facade. The shape of a large number of columns, this method does not need to set up concrete structural columns, which is conducive to changing the facade effect of the building at will, and arbitrarily placing the position of the visible styling columns on the facade; economical: save a lot of concrete structural columns on the facade Reinforced concrete materials and construction costs; Applicability: The bearing capacity can be improved by adjusting the length of the eaves overhangs, and there is no need to make structural columns to affect the architectural effect.

Detailed ways

The specific implementation manner of the present utility model is described in further detail below.

As shown in Figures 1 to 4, the utility model provides an ancient building eaves structure, which includes a frame column 10, a main beam 12 erected on the frame column 10, and a secondary beam 14 horizontally arranged on the main beam 12. The main beam 12 includes an upper beam 16 and a lower beam 18 parallel to each other. The main beam 12 and the secondary beam 14 are also provided with inclined beams 20 extending obliquely to the outside and below to form the eave structure. This is the most common basic structure of eaves in antique buildings.

Corresponding positions of the frame column 10 and the secondary beam 14 are provided with diagonal braces 22 extending obliquely to the outside and upwards, and the free ends of the diagonal braces 22 are connected to the diagonal beams 20 .

A filling wall 24 is provided between the upper beam 16 and the lower beam 18 , and one end of the corresponding diagonal brace 22 of the secondary beam 14 abuts against the upward flange of the lower beam 18 .

Furthermore, the connection between the filling wall 24 and the diagonal brace 22 adopts a full-beam stirrup encryption structure to improve the force-bearing structure.

Furthermore, the connection between the main girder 12 and the diagonal brace 22 adopts a longitudinal steel bar or a diameter of the stirrup plus one level to improve the force-bearing structure.

Further, the inclined beam 20 adopts tension-bending members to improve the stress-bearing structure.

Further, the braces 22 are all bending components to improve the stress-bearing structure.

The above embodiment is only one implementation mode of the present utility model, and its description is relatively specific and detailed, but it should not be construed as limiting the patent scope of the present utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
