Description

Eaves mouth structure of archaize building

Technical Field

The utility model belongs to the technical field of the industrial building construction, concretely relates to archaize building eaves mouth structure.

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

The above-mentioned not enough to prior art, the to-be-solved technical problem of the utility model is to provide a building eaves mouth structure modelled after an antique avoids because of adding the armpit part comparatively weak, leads to the relatively poor problem of eaves mouth structural strength, gains the rigid coupling to the rafter and all better effect to the support intensity of corning.
