Abstract

The technical scheme of the utility model is that: two ends of a wall is provided with composite columns, and are connected with upper and lower ring beams composed by cast-in-place floors; the middle of the wall is a wall body built by concrete, small hollow blocks or porous bricks or other wall materials, no core columns is used in the wall body, an reinforcing steel bar belt is arranged at every 800-1000 mm height to compose a wall body constraining the combined masonry structure. In the whole building, a new structure system with a high seismic strength which is convenient to construct and has an economical cost is generated, the utility model can be used for six-floor housing buildings, the anti-shattering degree is bigger that 8 degree, the construction difficulty and the civil cost are similar to a brick-concrete structure. According to requirements for seismic resistance protection by 8 degree shattering, small high-rise houses or bottom frame small high-rise houses can be built through the technical scheme.

Description

The assembled wall structure

The utility model relates to a kind of assembled wall structure of using in the building.

The design of building masonry wall is to decide according to the character of building, and its structure is diversified, and with regard to housing construction, many architects' painstaking effort have also been poured in the design of body of wall and transformation.Widely used loam brick of past is owing to damaged large stretch of farmland and land resources, the use of having to ban use of and limit in some areas, concrete small size hollow building block is the preferred material of instead of clay brick, use the history of existing last 100 years abroad, domesticly also progressively promote the use of already, nineteen ninety-five has been worked out corresponding industry standard: JGJ/T14-95, but when being built in the house that uses the earthquake zone, must adopt the stem stem structure that is inserted with reinforcing bar and placing of concrete in the hole in hollow concrete block wall; Vertical joint bar should connect the wall body, and with basis or grade beam in the embedded bar welding; Answer multinomial construction requirements such as integral cast-in-situ with collar tie beam.This just makes troubles to construction, has also increased cost, and if do not tamp building block in a large number, reduces the actual hollow rate of building block, must limit the building height in house.Along with development of rural economy, vast rural area and middle townlet will build multi-storey building and small-sized public building more on a large scale, also press for the novel wall of a kind of realistic construction technology of development.

In order to overcome the deficiencies in the prior art, strengthen the anti-seismic performance in house, design a kind of novel assembled wall structure.

The technical solution of the utility model is: the body of wall two ends are provided with coupled column, connect into a frame type integral body with the formed collar tie beam of cast-in-situ floor up and down, the centre is built into body of wall with materials for walls such as concrete small size hollow building block or porous bricks, body of wall is interior without stem stem, per 800～1000mm highly locates to be provided with the arrangement of reinforcement band, reinforcing bar in the arrangement of reinforcement band is connected with reinforcing bar in the coupled column, forms the body of wall of binding masonry combining structure; Door and window hole in the body of wall is established prefabricated units and is connected with collar tie beam, and the top is cast-in-place lintel.

Need do the defective of the big stem stem structure of difficulty of construction when the utility model overcomes the concrete small size hollow building block masonry panel, not use loam brick to make materials for wall.In whole building since with the combination of coupled column, arrangement of reinforcement band, cast-in-situ floor and collar tie beam, produce a shock strength height, be convenient to construction, the new structure system of cost economic is used for six layers of housing construction, the shatter resistant degree is greater than 8 degree, and difficulty of construction and civil engineering cost are close with brick mix structure.According to 8 degree degree of splitting requirementss for fortification against earthquake, can build little high residential building with this method, or the little high residential building of bottom frame.

Below in conjunction with accompanying drawing the utility model is done narration further.

Fig. 1 is the assembled wall structural representation; Fig. 2 is the door and window structure schematic diagram.

1-coupled column among the figure, the 2-collar tie beam, 3-arrangement of reinforcement band, 4-retrains building block, 5-gingival cyst of mucous gland in the newborn stubble, the cast-in-place lintel of 6-, 7-frame prefabricated units.

From Fig. 1 as seen, the two ends of every wall are the coupled column (1) of monolithic reinforced concrete structure, it is up and down the formed collar tie beam of cast-in-situ floor (2), connect into a frame type integral body with coupled column, middle constraint building block (4) is porous brick or concrete small size hollow brick etc., build by laying bricks or stones in wrong hole, and coupled column is provided with gingival cyst of mucous gland in the newborn stubble (5); Per 800～1000mm highly locates to be provided with arrangement of reinforcement band (3), thickness 60～80mm.Both sides, door and window hole are prefabricated units (7) among Fig. 2, are welded to connect with collar tie beam (2), lintel (6) and arrangement of reinforcement band (3), have formed a combining structure body of wall that rigidity is very big like this.

Embodiment of the present utility model in 2000 in building water conservancy institute of Tsing-Hua University structural experiment chamber by building a full scale test building at 1: 1,13.85 meters of long 9.48 meters, wide 7.38 meters, height overall, 2.7 meters of floor heights, totally 5 layers.Wall body structure all adopts technical scheme described in the utility model.Outer wall thickness 360mm, the Kp2 moulded coal spoil porous brick building block of Mu10, specification is 240 * 115 * 90; Interior wall thickness 200mm, the Mu10 concrete small size hollow building block, the specification of most building blocks is 390 * 190 * 190; The M10 composite mortar, C20 concrete, I, II grade reinforcing steel; Add composite column structure with in-situ reinforced concrete slab, collar tie beam, 33 days practice of construction cycles, average every layer 6.6 days; The masonry residential of engineering real cost and common brick is suitable.During test, when load added to and is equivalent to shatter resistant degree 8 and spends, structure was intact, still has elastic stage, when load is increased to when being equivalent to shatter resistant degree 9 and spending, had only hair check.

Claims

1, a kind of assembled wall structure, it is characterized in that the body of wall two ends are the coupled column (1) of cast-in-situ steel reinforced concrete, it is up and down the formed collar tie beam of cast-in-situ floor (2), they connect into a frame type integral body, middle binding masonry (4) is concrete small size hollow building block and porous brick, build by laying bricks or stones in wrong hole, does not do the stem stem structure.
