Description
Technical Field
The invention belongs to the technical field of industrial building construction, and particularly relates to an eaves structure of an antique building.
Background
With the continuous development and research of historical culture, archaized buildings are more and more appeared in life as a kind of humanity continuation; traditional ancient building adopts the timber structure to build usually, and in order to pursue the beauty of classical architecture among the modern building trade, can generally construct the building body that accords with the mechanical strength requirement through reinforced concrete structure, and have traditional classical architecture characteristic, reinforced concrete archaize building eaves mouth is exactly one of them common archaize building structure.
The cornice is also called eave, is the joint part of the roof and the wall body of the outer wall, and is used for conveniently removing the rainwater on the roof and protecting the wall body; in the ancient building, the upper end of eaves post loops through crossbeam, bracket arch, seals arch bar and round purlin from bottom to top and supports the roof boarding, and the part that the outer wall was stretched out to the roof boarding is called the cornice, and the below of cornice still generally is equipped with a plurality of rafters that outwards extend along the roof boarding in order to strengthen the support to the cornice at the interval. In order to improve the mechanical strength of the building in the pseudo-classic architecture, referring to a reinforced concrete structure of the cornice of the pseudo-classic architecture shown in the attached drawing 1, at present, the cornice of the pseudo-classic architecture generally adopts a concrete structure beam 8 to replace a wooden cross beam, then a reinforced net structure is arranged on the basis of the concrete structure beam 8, a concrete roof panel 1 is formed by pouring, a semicircular purlin 3 is further arranged below the concrete roof panel 1 in a protruding mode near the middle of a cornice, the semicircular purlin 3 is used for replacing a circular purlin and plays roles in decoration and hanging connection, an arch sealing plate (not shown in the figure), an arch hopper (not shown in the figure) and rafters 2 are all prefabricated by concrete, wherein the prefabricated arch sealing plate of the concrete is arranged below the semicircular purlin 3 and fixedly connected with the concrete structure beam 8 so as to be convenient for hanging the arch hopper; the prefabricated concrete bucket arches play a role in decoration, when the prefabricated concrete bucket arches are installed, a plurality of bucket arches are fixedly connected to the outer side of a concrete structure beam 8 at intervals and located below an arch sealing plate, the bucket arches are fixedly connected with the concrete structure beam 8 and the arch sealing plate respectively, prefabricated concrete rafters 2 are fixedly connected to the lower portion of an eave, then the two sides of the rafters 2 close to the concrete structure beam 8 are independently formwork-poured to form right-angled triangular columnar haunching portions 4, the bevel edge faces of the haunching portions 4 are fixedly connected with the eave, the straight edge faces of the haunching portions 4 are fixedly connected with the concrete structure beam 8, the two sides of the haunching portions 4 are fixedly connected with the corresponding two rafters 2 respectively, and therefore the rafters 2 and the concrete structure beam 8 are connected into a whole to provide support for the eave.
In the cornice of the antique building, the haunching part is weak, the fixing effect on rafters is poor, the supporting force on cornices is limited, the arch sealing plate is in an overhanging arrangement state, and the arch sealing plate is easy to deform and crack after a long time because the arch hopper and the arch sealing plate are prefabricated by concrete; meanwhile, the haunching part needs to be separately supported and poured among prefabricated rafters; it is thus clear that present archaize building eaves mouth not only is under construction complicacy, and structural strength is relatively poor, has certain potential safety hazard.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the cornice structure of the antique building, so that the problem of poor structural strength of the cornice caused by weak haunching parts is solved, and the effects of fixedly connecting rafters and supporting cornices are better.
In order to solve the technical problems, the invention adopts the following technical scheme:
the cornice structure of the pseudo-classic architecture comprises a concrete structure beam, a concrete roof panel is poured above the concrete structure beam, the part of the concrete roof panel, which extends out of the concrete structure beam, is formed into a cornice, and a panel reinforcement cage is embedded in the concrete roof panel; the concrete roof slab is characterized in that a semicircular purlin is arranged at a position, close to the middle part of the cornice, below the concrete roof slab in a protruding mode, a semicircular purlin steel reinforcement cage is connected with the panel steel reinforcement cage and correspondingly embedded in the semicircular purlin, a plurality of concrete prefabricated rafters are fixedly connected to the lower part of the cornice at intervals along the length direction of the concrete structure beam, the root parts of the rafters are fixedly connected with the concrete structure beam and the cornice through haunched parts respectively, the haunched parts are of thickened structures with parallelogram-shaped cross sections, and the haunched parts are fixedly connected to the lower surface of the cornice and fixedly connected between the concrete structure beam and the semicircular purlin;
an armpit reinforcing cage is embedded in the armpit part, the armpit reinforcing cage is connected with a panel reinforcing cage or reinforcing steel bars embedded in a concrete structural beam, the concrete roof panel, the semicircular purlin and the armpit part are of an integrated pouring structure, and the root of the rafter is embedded in the armpit part;
a plurality of wooden bucket arches are arranged below the semicircular purlins at intervals along the length direction of the concrete structural beam, and the bucket arches are fixedly connected with the semicircular purlins and the concrete structural beam through a plurality of fasteners respectively; an arch sealing plate is arranged between the bucket arch and the semicircular purlin and is fixedly connected with the concrete structural beam.
In the invention, the haunch part, the concrete roof panel and the semicircular purlin are cast in situ together and are formed at one time, so that the construction procedures are reduced, the construction period is shortened, and the construction cost is reduced; the haunching part adopts a thickened structure with a parallelogram-shaped section and extends to the semicircular purlin, so that the haunching part has a better supporting effect on cornices, the haunching part completely wraps the roots of the rafters, the fixing effect on the rafters is better, and the effective support on the cornices is facilitated; compared with the triangular columnar haunches adopted by the cornice of the prior archaized building in the background art, the haunches adopted by the invention have better effects on rafter fixing and cornice supporting;
in the invention, the wooden bracket is adopted, compared with a concrete prefabricated bracket, the wooden bracket has lighter weight and is convenient to be stably and fixedly connected with a concrete structural beam; the wooden bracket is directly and fixedly connected with the semicircular purlin by adopting expansion bolts to penetrate through the arch sealing plate, so that the arch sealing plate is not influenced by the gravity of the bracket; simultaneously, compare in concrete prefabricated bracket, wooden bracket is difficult cracked, is convenient for transport, and is also better to ancient building's reductibility, even appear droing, the destruction that causes is also littleer, and the security is higher.
