Description
Technical field
The utility model relates to a kind of pitched roof concrete cast-in-situ construction servicing unit.
Background technology
Pitched roof is the normal a kind of roofing form that adopts in the building, and two kinds of forms of prefabricated room panel and present room walling panel are arranged, and the construction of prefabricated room panel is comparatively simple; Present room walling panel since the existence of the gradient build in the process concrete, can produce concrete along the slope landing and concrete disintegration phenomenon; Existing a kind of way is to be parallel to the roofing soffit formwork layer of steel wire net is set, Yi Bian build, Yi Bian make real; The method causes the construction uneven thickness easily, causes roof leakage; Another kind of way is through vertical separation keel, panel and bottom surface template are set; Rely on the restriction of upper panel, cornice shrouding and bottom surface template in the concreting process; Concrete landing along the slope, though the method can be divided into vertical bar section reduction segregation probability through separating keel with construction to a certain extent, but bigger for the gradient of roofing; Such as spending greater than 60; Possible because of the landing of the bigger generation concrete of the gradient in bar shaped construction section scope, and it is in uneven thickness to cause roofing concrete to be built, thus leave over construction hidden danger.
The utility model content
The purpose of the utility model provides a kind of wide-angle pitched roof concreting isolation-proof device, solve pitched roof and build in the process, and concrete is the landing along the slope easily, and concrete is emanated easily, causes the technical problem of roof leakage; And solve because the restriction of existing working measure, cause the pitched roof gradient can not too big problem.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of wide-angle pitched roof concreting isolation-proof device; Comprise roofing bed die from eaves aspect ridge; Also comprise spacing gauze wire cloth; Said spacing gauze wire cloth is arranged on the roofing bed die from eaves aspect ridge at interval, forms between the adjacent spacing gauze wire cloth and successively builds horizontal construction section, is connected through positioning bolt between said spacing gauze wire cloth bottom surface and the roofing bed die.
Said positioning bolt central authorities are welded with the sealing sheet, full weld between said sealing sheet and the positioning bolt.
The spacing of said positioning bolt is 1000mm～1500mm.
The diameter of said sealing sheet is 50mm～80mm.
The spacing that is provided with of said spacing gauze wire cloth is 1m～2m.
The mesh of said spacing gauze wire cloth is 0.45mm～0.65mm.
Compared with prior art the utlity model has following characteristics and beneficial effect:
Through being set, spacing gauze wire cloth is divided into the section construction to the roofing concrete construction; Limited the width of the section of construction; Reduced the probability of segregation, simultaneously because the restriction of spacing gauze wire cloth is arranged, in the process of vibrating, can not cause concrete along the slope landing and concrete disintegration phenomenon; Make concrete guarantee uniformity, density and the Forming Quality of concrete formation thickness in the confined space moulding of slope.The said device of the utility model can realize that the concrete compaction of design grade pitched roof between 15 °～75 ° builds, and has enlarged the scope of application of existing pitched roof.
Through between roofing bed die and spacing gauze wire cloth, positioning bolt being set, when being connected to roofing bed die and spacing net together, can carry out highly spacing.Not only can guarantee structural thickness, can also prolong the infiltration route, increase resistance percolating water.
Through at positioning bolt central authorities welding sealing sheet, can prolong the infiltration route, increase resistance, thereby stoped the concrete slurry of just having built to be emanated percolating water.
The utility model can be widely used in the cast-in-situ concrete construction of pitched roof, the especially construction of heavy grade pitched roof cast-in-situ concrete.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fig. 1 is the utility model structural representation.
Fig. 2 is Figure 1A-A sectional view.
Fig. 3 is the B-B sectional view of Fig. 2.
Reference numeral: 1-roofing bed die, the spacing gauze wire cloth of 2-, 3-positioning bolt, 4-sealing sheet.
The specific embodiment
Embodiment is referring to Fig. 1, Fig. 2 and shown in Figure 3; A kind of wide-angle pitched roof concreting isolation-proof device; Comprise the roofing bed die 1 from eaves aspect ridge, also comprise spacing gauze wire cloth 2, said spacing gauze wire cloth 2 is arranged on the roofing bed die from eaves aspect ridge at interval; Form between the adjacent spacing gauze wire cloth and successively build horizontal construction section, be connected through positioning bolt 3 between the bottom surface of said spacing gauze wire cloth 2 and the roofing bed die 1.
Said positioning bolt 3 central authorities are welded with sealing sheet 4, full weld between said sealing sheet 4 and the positioning bolt 3.
The spacing of said positioning bolt 3 is 1000mm～1500mm.
The diameter of said sealing sheet 4 is 50mm～80mm.
The spacing that is provided with of said spacing gauze wire cloth 2 is 1m～2m.
The mesh of said spacing gauze wire cloth 2 is 0.45mm～0.65mm.
Confirming of spacing between spacing gauze wire cloth and the roofing bed die just can be controlled the thickness of pitched roof cast-in-situ concrete.Building along the eaves Section of Outer Ring Line of roofing concrete is that the loop wire of 50cm is by carrying out concreting clockwise with the width; And before the concrete initial set of building at first, hand over circle; Build for the loop wire of 50cm carries out second circle by wide then; Gradually to ridge near, accomplish the pouring construction of whole roofing concrete.Concrete construction is accomplished and was arranged the mason to carry out floating, the receipts light (when roofing concrete is built, carrying out for the first time) of concrete roof for the second time in 7 days afterwards.Wherein, When sloping bottom pour mold is built concrete; Because the shrouding at spacing gauze wire cloth of the first order and roofing bed die and the end, slope constitutes the opening that concreting is only arranged along the gradient; And other orientation is airtight, thereby directly adopts tamping equipment to tamp concrete in the spacing gauze wire cloth of the first order and the roofing bed die and the first order concreting space that shrouding constituted at the end, slope.
The high baffle plate of 50cm can be set temporarily, aggregate landing when avoiding building in that the template face is suitable for reading during concreting.Arrange closeer pitched roof for reinforcing bar, can adopt ￠ 30 small vibrating rods to vibrate.Build and to adopt hand hammer to knock inspection in the process whether to have built closely knit.
During concreting, tiltedly eaves are starting point, and circulation is built around roofing one week, can install the spacing gauze wire cloth of one deck after having built one deck, and spacing gauze wire cloth is installed step by step piecemeal, and concreting step by step circulates successively each other and carries out, until building end then.
The pitched roof bigger for physical dimension, that girth is bigger, the speed that should before being construction, build according to every layer concrete is calculated the time of building.If necessary, can with due regard to add retarding agent, avoid producing cold seam before the concrete overlap joint.
Water seasoning is promptly answered in general concrete final set, and curing time is no less than 14d.
Spacing gauze wire cloth can reach 1.2N/mm at concrete strength 2Remove the back, and care should be used to during dismounting is forbidden random sled, in order to avoid cause the sealing bolt looseness, the roofing bed die should be a foundation with test cube in the same condition intensity according to the regulation that the beam slab form removal is arranged in the standard, gives form removal.
The characteristics less to the pitched roof thickness of slab, that reinforcing bar is closeer, coarse aggregate should adopt 10cm～20cm crushed gravel.
