Abstract

The utility model discloses a jack arch structure with the bricking span of 2800mm, which comprises a jack arch part combined wall body, wherein the jack arch part combined wall body is arranged at an lintel part above doors and windows; and a bricking jack arch is arranged outside the jack arch part combined wall body. The jack arch structure is characterized in that porous standard bricks and L-shaped special porous bricks are sequentially and alternatively cemented and bricked to form a jack arch brick body having a staggered effect at the inner side from one side to the other side; hanging bars and steel reinforcing bars form a jack arch structure of 2800mm; the diameter phi of each hanging bar is 8-20mm; the hanging bars are welded on a group of expanding bolts which are positioned at the position on an original frame beam above a door window, wherein a hole is drilled every 500 meters; the diameter phi of each reinforcing steel bar is 10-20mm; the reinforcing steel bars penetrate through holes of the jack arch brick body, are inserted into the parts which are 200mm away from the surfaces of dry walls at the two sides of the jack arch brick body and are connected with the hanging bars; the jack arch brick body is cast by lintel concrete, so that the concrete is fully occluded with staggered mortar at the inner side of the bricked jack arch brick body for accommodating pre-penetrated reinforcing steel bars to form the jack arch structure; and the outer side of the jack arch structure still presents the visual effect of the dry walls. The bricked jack arch structure of the jack arch structure has reasonable stress and is reliable and safe.

Description

The jack arch structure that a kind of brick span is 2800mm

Technical field

The utility model relates to a kind of brick jack arch structure, relates in particular to a kind of brick large span jack arch structure, and specifically, the jack arch structure that to relate to a kind of brick span be 2800mm belongs to the masonry structure field of engineering technology.

Background technology

Brick jack arch structure is the beam construction excessively on the door and window in the building with brick-concrete structure, usually abbreviates jack arch structure (to call jack arch in the following text) as.The purpose of brick jack arch is set, is to make brick jack arch bear the load that the above masonry of door and window mouth end face is conducted oneself with dignity and cover plate of upper layer transmits, and load is passed to the masonry of door and window both sides in order to avoid damage doorframe and window frame by pressure.In the prior art, brick jack arch is to be formed by edge-on the building by laying bricks or stones of standard brick, and its thickness is identical with wall thickness, highly is generally 120mm and 240mm, and its net span should not surpass 1.2m, is widely used in the little wall of hole clear span, can satisfy the requirement of bearing capacity.

Be located in the apartment with hotel-styled services engineering of the institute in road, Tai'an, Tianjin, No. four institutes, the engineering structures form is a frame-shear wall, nine layers, underground two layers on the ground.Building eaves height 35.85m.Wherein, the first floor and nine is high layer by layer is 4.8m; All the other each layers are typical floor, and floor height is 3.75m.Exterior wall is established and dry wall is built by laying bricks or stones.The outer armpit wall of exterior wall is the how empty standard brick of the thick shale of 129mm, and the armpit wall is a shale building-block behind the 200mm within the walls outward.Major part be the wide cavity of 60mm between the inside and outside armpit wall, in fill out the pollopas foaming and do insulation filling use.The span width of the outer eaves wall body door or window hole of this project is designed to 2800mm.

Adopting the prior art job practices to build span by laying bricks or stones is the 2800mm brick flat arch, and this jack arch can not satisfy the technical requirements of bearing capacity far away, the serious problems that the door and window mouth occurs damaging by pressure because of existing structural integrity poor in actual applications.

Under the brick job practices of tradition can't the situation of brick large span jack arch, how designing to build by laying bricks or stones and have the superior structural globality and satisfy requirement for bearing capacity and embody the span 2800mm jack arch structure of the impression effect of brick flat arch, is building construction technology personnel's a problem that needs to be resolved hurrily; Guaranteeing the safe handling of brick large span jack arch structure, also is the problem that the building construction technology personnel very pay close attention to.

The utility model content

The purpose of this utility model is to solve the problem that above-mentioned prior art exists, providing a kind of has the superior structural globality and satisfies requirement for bearing capacity and embody the span 2800mm jack arch structure of the impression effect of brick flat arch, thereby solve the problem that above-mentioned prior art exists, and satisfy the technical requirements of bearing capacity.

For realizing the purpose of this utility model, the technical scheme that is adopted is:

The jack arch structure that a kind of brick span is 2800mm, comprise that the outside, lintel place, door and window top is the jack arch part assembled wall of brick jack arch, it is characterized in that: alternately drape over one's shoulders ash successively by a porous standard brick and complicated-shape porous brick of " L " shape and build group by laying bricks or stones and build and constitute the jack arch brick body that the inboard has wrong raft effect by a side direction opposite side, hang muscle and reinforcing bar and form the jack arch structure of 2800mm, the described muscle that hangs, its diameter is φ 8mm～20mm, it is welded on the bolt that rises of next group of every 500mm place's perforating on the original frame concrete beam in door and window mouth top, on one group of bolt that rises, weld 2 and hang muscle, 2 are hung the muscle spacing is a brick, described reinforcing bar, its diameter is φ 10mm～20mm, it passes the hole of brick flat arch brick body, and be inserted into 200mm place in the dry wall of jack arch brick body both sides, and with hang muscle 6 and be connected, described jack arch brick body, after building the lintel concrete, make the abundant interlock of wrong raft of concrete and brick jack arch brick body inboard, to wear reinforcing bar in advance wraps up in it, form the jack arch structure, its outside still presents the impression effect of plain brick wall

Described porous standard brick, its contour structures are that corner angle are neat, do not have crooked, crackle, and color is even, the porous brick size that appearance and size is up to specification.

Described " L " shape special form brick is made of the L-shaped shape of standard porous brick cutting process.

Advantage and beneficial effect:

By above technical scheme as can be known, the utility model has following advantage and beneficial effect under the structure configuration of excellence:

The utlity model has modern design, project organization is reasonable, and is pratical and feasible, and realizes the advantage of the impression effect of outer eaves dry wall.

The utility model has strengthened the bearing capacity of brick flat arch lintel greatly by wearing brick reinforcing bar and the use that adds of hanging muscle, makes the jack arch member have good structural integrity, satisfies requirement for bearing capacity, thereby has guaranteed the beneficial effect in its application life.
