Abstract

The utility model discloses a slope roof cast-in-place concrete structure which comprises a bottom layer template and vertical keels, wherein the bottom layer template is installed according to required slope roof gradient; and the vertical keels are distributed from the slope bottom to the slope top along the trend of the slope roof. The slope roof cast-in-place concrete structure is characterized in that one end of the limit sealing bolt is connected, limited and fixed with the bottom layer template, and the other end is limited and fixed with the vertical keels; the vertical keels on the slope roof are distributed at intervals; side pressing keels are additionally nailed at both side edges of each surface layer template; the surface layer template is arranged between the adjacent vertical keels at two sides; the lower edge of the surface layer template aligns to the lower edge of each vertical keel; and the side pressing keel at each side of the surface layer template is firmly nailed on the vertical keel at the corresponding side. Accordingly, when pouring, the utility model can not cause phenomena of concrete falling along the slope and concrete disintegration in the vibrating process due to the limit of the upper surface layer template and the bottom layer template of the concrete, is used for moulding the concrete just in the limited space of the slope roof and ensures uniformity and compactibility of moulding thickness and moulding quality of the concrete.

Description

The pitched roof cast-in-place concrete structure
Technical field:
The utility model relates to a kind of pitched roof cast-in-place concrete structure, is applicable to the structure of the pitched roof cast-in-situ concrete of the density of common design grade between 25 °~60 °.
Background technology:
Often take to install bottom surface, slope template in the construction of traditionally pitched roof or on the reinforcing bar face additional layer of steel wire net build, make real, but because the slope is steep, in the process of vibrating, often cause concrete along slope landing and concrete disintegration phenomenon, make concrete not have natural moulding under the state that constraint is landing being on the slope.Casting and compacting of concrete density and molding thickness are difficult to controlled, and construction quality is difficult to produce a desired effect, and stay to concrete structure construction and ooze, leak the hidden danger common fault.
Summary of the invention:
The purpose of this utility model is to provide a kind of simple, convenient pitched roof cast-in-place concrete structure, adopts this structural concrete to water to smash to be easy to the effect that reaches closely knit after the moulding, guarantees concrete pouring quality.Adopt between vertical keel and bottom template and carry out clamping, location by spacing sealing bolt, with this foundation of controlling the utility model thickness of structure and the surface layer template being installed, the surface layer template is then made in advance, adopt during construction and put step by step, install, build step by step, template is installed with concreting and is not disturbed work plane mutually, circulation is carried out successively mutually, simple, convenient, can guarantee that structure is closely knit, sectional dimension correctly reaches surfacing, help guaranteeing the quality of concrete formation.
The purpose of this utility model is achieved in that described pitched roof cast-in-place concrete structure, comprise by the mounted bottom template of the pitched roof gradient of construction requirement, according to the trend vertical keel that extremely sloping direction of pushing up is arranged along the end, slope of pitched roof and spacing sealing bolt and surface layer template, its design feature is that described spacing sealing bolt one end is connected spacing fixing with the bottom template, the sealing bolt other end is spacing fixing with vertical keel, the alternate layout of vertical keel on pitched roof, add nail at the dual-side of every chunk facing template the side pressure bone is arranged, the surface layer template is placed between the vertical keel of adjacent both sides, the lower limb of described surface layer template aligns with the lower limb of vertical keel, by iron nail with the every side side pressure bone of surface layer template and the vertical keel stickfast of respective side.
The purpose of this utility model can also be achieved through the following technical solutions, described pitched roof cast-in-place concrete structure, its characteristics are first order surface layer template for set surface layer template between the vertical keel of slope end section start in adjacent both sides, and first order surface layer template and bottom template and the shrouding at the end, slope constitute first order concreting space.Described pitched roof cast-in-place concrete structure, its characteristics be for adding weldering sealing sheet at the medium position of every sealing bolt, tightly be connected for full weld between sealing sheet and the bolt.Described pitched roof cast-in-place concrete structure, its characteristics are that described vertical keel comprise lumps of wood Two bors d's oeuveres and little batten, and the space between lumps of wood Two bors d's oeuveres is fixed with little batten clip nail.
Advantage of the present utility model: the utility model is after the gradient (as in the gradient between 25 °~60 °) installs pitched roof bottom template on request, trend according to pitched roof is arranged vertical keel along slope the end (being roofing cornice place) to the direction on top, slope, carry out clamping, location by spacing sealing bolt between vertical keel and bottom template, with this foundation of controlling the utility model thickness of structure and the surface layer template being installed.It is prefabricated that the surface layer template then gives prior classification according to the result of setting-out, during installation the surface layer template put between the into adjacent vertical keel, by iron nail surface layer template and vertical keel stickfast got final product.The surface layer template is installed in carpenter's classification from bottom to up around pitched roof, whenever the formed space that is used for concreting gets final product concreting between surface layer template and the bottom template with regard to constituting to install one-level, and the mason builds the concrete between mounted each grade surface layer template and the bottom template around pitched roof.Adopt step by step the method for installing, building step by step, circulation is carried out successively mutually, until building end.When sloping bottom pour mold is built concrete, because the shrouding at first order surface layer template and bottom template and the end, slope constitutes the opening that concreting is only arranged along the gradient, and other orientation is airtight, thereby directly adopt tamping equipment that concrete is tamped in first order surface layer template and the bottom template and the first order concreting space that shrouding constituted at the end, slope, concrete when building is because the surface layer template on top, the restriction of the shrouding at the bottom template and the end, slope, in the process of vibrating, can not cause concrete along slope landing and concrete disintegration phenomenon, make the concrete can only be in the confined space moulding of slope, so just guaranteed the uniformity of concrete formation thickness, guaranteed that the pitched roof concrete structure is closely knit, sectional dimension correctly reaches surfacing, helps guaranteeing the quality of pitched roof concrete formation.
