Abstract
The invention discloses a method and a structure for preventing house top floor wall body cracks. During the house reinforced concrete roof manufacturing, the middle position of a roof boarding as a reinforced concrete roof of the whole unit floor is directly supported and fixed on a ring beam on a wall body in the middle part position or on the wall body in the middle part position of the unit floor, and meanwhile, other positions of the roof boarding are supported on the ring beams of other wall bodies or on other wall bodies of the unit floor a horizontal sliding layer. Through the arrangement of the horizontal sliding layer between the roof boarding and the ring beams on the top of the wall body, the relative movement between the roof boarding and a load bearing wall body is allowed, and the horizontal pushing, pulling and pressing stress generated by the roof boarding on the wall body is avoided or reduced, so the cracks of the wall body at the top floor of the house are effectively prevented or reduced. The structure and the method have the advantages that the structure is simple, economy and practicability are realized, and the construction is fast and convenient.
Description
Technical field
the present invention relates to a kind of method and structure thereof that prevents top wall crack, house, belong to the link technique field of body of wall and roof panel in building field.
Background technology
thermal cracking is the construction work common fault, and buildings in general builds up and occurs afterwards in one, two year.Crack width is between 1～2mm, and majority occurs in the mixed house of brick.Quite a few is brick mix structure for China's building construction, general is all that the steel bar concrete roof system is directly built on the collar tie beam be fixed on body of wall or on body of wall, do not take in design any effective measures that prevent that stress from producing, during construction for the quickening progress, its stress is well discharged, thereby is easy to make top wall crack, house to occur.Due to the steel bar concrete roof system, to be subject to solar irradiation Area Ratio brickwork much bigger, the time of exposing to sunlight is all longer than other any positions, and the thermal resistance energy force rate brickwork thermal resistance ability of steel bar concrete roof system is very different, the steel bar concrete linear expansion coefficient is 2～4 times of brickwork linear expansion coeffcient, thereby the distortion difference that steel bar concrete roof system temperature causes is more much bigger than brickwork, causes between combined masonry producing relative displacement.The displacement of steel bar concrete roof system is retrained by brickwork, brickwork is produced to shearing stress, brickwork tension shear strength is more much lower than steel bar concrete tension shear strength, low to house top layer brickwork requirement of strength during design, produce like this tensile strength that tension stress surpasses brickwork in member, cause the brickwork crack to produce.So connected mode of existing steel bar concrete roof system and house top wall or not ideal enough.
Summary of the invention
the object of the invention is to, provide a kind of and can effectively prevent or alleviate the method and the structure thereof that prevent top wall crack, house that causes wall body slit because of expanding with heat and contract with cold of roof panel, thereby overcome the deficiencies in the prior art.
technical scheme of the present invention is achieved in that and of the present inventionly a kind ofly prevents that the method in top wall crack, house from being, when the steel bar concrete roof system that carries out house is made, to directly be supported and fixed on as the position, middle part of the roof panel of the steel bar concrete roof system of whole unit floor on the body of wall at position, middle part of unit floor or on the collar tie beam on the body of wall of position, middle part, other position of this roof panel will be supported on by the horizontal slip layer on other body of wall of this unit floor or on the collar tie beam on other body of wall simultaneously.
prevent that according to the of the present invention a kind of of said method structure the structure in top wall crack, house from being: this structure comprises the body of wall of unit floor, body of wall top in the whole unit floor outside is provided with collar tie beam, top at whole unit floor is provided with the roof panel as the steel bar concrete roof system, the position, middle part of this roof panel is fixedly connected on the body of wall at position, middle part of unit floor or is fixedly connected on the collar tie beam on position, the middle part body of wall of unit floor, other position of roof panel is supported on other body of wall of this unit floor by the horizontal slip layer or on the collar tie beam on other body of wall.
the length at the position, middle part of above-mentioned roof panel is 1/4～1/2 of this unit building layer plane length, and its width is 1/4～1/2 of this unit building layer plane width.
above-mentioned horizontal slip layer comprises two-layer malthoid, is provided with lubricating layer or deformation layer between two-layer malthoid.
above-mentioned lubricating layer or deformation layer are talcum bisque or rubber lamella.
be provided with floated coat on the surface of above-mentioned body of wall and the bottom surface of roof panel, and be provided with fracture at the floated coat of surface of wall and the corresponding horizontal slip layer of the floated coat place of roof panel bottom surface.
owing to having adopted technique scheme, the present invention is by arranging the horizontal slip layer between body of wall top and roof panel or between the collar tie beam at body of wall top and roof panel, allow roof panel to relatively move except the position at position, middle part, between all the other positions and bearing wall, thereby effectively avoid or reduced roof panel when generation is expanded with heat and contract with cold on body of wall generation level push away, draw, the impact of compressive stress, thereby effectively prevent or alleviated the generation in top wall crack, house.So compared with prior art, the present invention can not only effectively avoid or alleviate the advantage that top wall crack, house produces in the present invention, but also there are simple and reliable for structure, the advantages such as structural stability good, economical and practical, quick construction.
