Justice.
In order to improve the flatness for pouring the Sloping roof plate to be formed, voids and pits phenomenon is reduced, as depicted in figs. 1 and 2, originally
Invention provides a kind of construction method of Sloping roof concrete structure, includes the following steps:
S1, Sloping roof support system 1 is built；
S2, end template 9 is installed on the inclined-plane of Sloping roof support system 1；Specifically, end template 9 are located at Sloping roof branch
The side of the inclined-plane direction Sloping roof plate to be poured of support system 1.
S3, the side banding steel cage for deviating from Sloping roof support system 1 in end template 9；
S4, dabbing processing is carried out in the joint part 2 that Sloping roof is connect with substrustion structure；
S5, exterior sheathing 10 is installed away from the side of end template 9 in steel reinforcement cage, and exterior sheathing 10 is reinforced；
S6, concreting is carried out；
S7, after concrete setting, remove exterior sheathing 10 and end template 9.
By above-mentioned setting, the double-template structure formed using end template 9 and exterior sheathing 10, avoid single formwork structure by
In no exterior sheathing 10 and caused by voids and pits phenomenon different degrees of existing for Sloping roof plate；And flatness is poor asks
Topic, can meet the requirement of construction very well.
Further, it before carrying out dabbing processing to joint part 2 in step s 4, needs to shift to an earlier date embedded water stop in joint part 2
Bolt 3.Specifically, in the present embodiment, water-proof bolt 3 is arranged at 2 top 200mm of joint part.Water-proof bolt 3 can
It is fixedly connected with end template 9 and exterior sheathing 10, after concreting, it is ensured that Sloping roof plate and substrustion structure
Joint part 2 be completely embedded, provide Sloping roof plate certain support force by joint part 2 so that Sloping roof plate stable structure,
Reach the requirement of design.
Swollen mould occurs in casting process in order to prevent, thus for construction bring it is unfavorable, further, in step S5, the bottom of at
The outside of template 9 is provided with the first fastening assembly, is provided in the outside of exterior sheathing 10 and sets with the first fastening assembly parallel interval
The second fastening assembly set, the first fastening assembly and the second fastening assembly are fixed by Screw arbor with nut at both-ends 8, so that external mold
The relative position of plate 10 and end template 9 is more fixed, so that exterior sheathing 10 and end template 9 can effectively will be not solidified
Sloping roof plate is located between exterior sheathing 10 and end template 9, guarantees the flatness on the surface of Sloping roof plate.By above-mentioned setting,
Guarantee that the distance between exterior sheathing 10 and end template 9 are constant, to effectively avoid Sloping roof plate pouring molding rear surface out-of-flatness
The problem of.
Specifically, in the present embodiment, the first fastening assembly includes the first flitch 5 and the first double steel pipe 4, the first flitch 5
Inclined direction along Sloping roof extends, and the first double steel pipe 4 extends along with the perpendicular direction of the inclined direction of Sloping roof, and first pair
The side that the first flitch 5 deviates from end template 9 is arranged in steel pipe 4, and the first double steel pipe 4 is fixed at one end of Screw arbor with nut at both-ends 8, right
The other end of screw rod 8 is drawn to connect with the second fastening assembly, so that the first double steel pipe 4 compresses the first flitch 5.With the first fastening assembly
Identical, the second fastening assembly includes the second flitch 7 and the second double steel pipe 6, and the second flitch 7 and 5 parallel interval of the first flitch are arranged,
Second double steel pipe 6 and 4 parallel interval of the first double steel pipe are arranged, and the second flitch 7 is arranged in away from exterior sheathing 10 in the second double steel pipe 6
Side, the second double steel pipe 6 are fixed at the other end of Screw arbor with nut at both-ends 8, and Screw arbor with nut at both-ends 8 is connect with the first flitch 5, so that second
Double steel pipe 6 compresses the second flitch 7.The first flitch 5 and the second flitch 7 are compressed by the first double steel pipe 4 and the second double steel pipe 6, from
And end template 9 and exterior sheathing 10 are compressed, guarantee the intensity with higher of exterior sheathing 10 and resistance ability, so that concreting
Journey is gone on smoothly, and effectively prevent rising the problem of being molded as Sloping roof plate out-of-flatness.
Further, because being installed using the double template of end template 9, exterior sheathing 10, pouring mouth can only pour from top,
And the plate thickness of concrete slab is relatively thin and its arrangement of reinforcement used is generally double-layer double-direction reinforcing bar, if pouring meeting using normal concrete
Increase difficulty of construction and it is difficult to ensure that concrete compaction rate.Taking into account the above, the concrete used in step s 6 be with
The self-compacting concrete of high trickling property and high divergence.
Further, pouring with concrete, using vibrating spear shaking concrete, after the completion of pouring, then with vibration
Stick vibration auxiliary is vibrated, to help the bubble being discharged in concrete.Concrete after finally needing to check solidification is with the presence or absence of sky
Hole, in the present embodiment, using carpenter's hammer tapping template, by sound inspection concrete, whether there is or not cavitations.
Further, Sloping roof support system 1 is built by steel pipe in step S1.It is built by using steel pipe, so that
There is Sloping roof support system 1 enough intensity to support Sloping roof plate.Sloping roof support system 1 is corroded in order to prevent,
To reduce the intensity of Sloping roof support system 1, adversely affected to construction, optionally, 1 surface of Sloping roof support system is set
It is equipped with antirust coat, in the present embodiment, antirust coat is paint, is isolated from the outside world by paint, thus to Sloping roof support system 1
Protection is provided.
The construction method of Sloping roof concrete structure provided by the present invention, the surface for pouring rear molding Sloping roof plate are flat
Preferably, the smooth no pitted skin in surface improves the waterproof performance of Sloping roof to whole degree；It can satisfy next procedure-cement-based penetrant knot
Brilliant Base Smoothness requirement, can save cement mortar screeding layer, therefore, save labour cost, the material of roof waterproof screed-coat
The investment of material expense.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating examples made by the present invention, and being not is pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Made any modifications, equivalent replacements, and improvements etc., should be included in the claims in the present invention within the spirit and principle of invention
Protection scope within.
