The structure of the embodiment is mainly made for the defects in the prior art, the prior art usually adopts the flow of erecting a scaffold, erecting a formwork, binding reinforcing steel bars and pouring concrete, and the following defects exist:
1. in the construction process of the cast-in-place reinforced concrete sloping roof, various sidelines and slope lines are more, most of the sidelines and the slope lines are mutually inserted and staggered, but for the sloping roof, the straight slope line and the flat slope surface are also the targets pursued by the building modeling. The design of inclined plane support horizontal thrust is required to be carried out on the standard requirement of the cast-in-place reinforced concrete sloping roof construction support, the horizontal thrust and vertical thrust resistance of the support are improved, and the design difficulty is invisibly increased.
2. The sloping roof is a symmetrical inclined plane in most cases, and the cross section of the internal beam is also trapezoidal, arc and the like, so that the shape of the reinforcing steel bar is the same as that of the beam. The special beams have extremely high requirements on steel bar binding, so how to improve the steel bar binding and processing quality becomes a key factor influencing the engineering quality. Present building design construction often all is the building form in big space, and this span that just leads to building beam slab itself is just big, and the plate thickness is also often great, and this just needs double-deck two-way to carry out the design arrangement of reinforcing bar in the board, and only the design of carrying out the reinforcing bar protective layer strictly, the production that concrete slab shrinkage crack can be avoided to the utmost to strict control protective layer thickness. Therefore, the steel bar engineering is also one of the key points that the construction quality of the cast-in-place concrete sloping roof is difficult to control.
3. The concrete construction must consider the sequence of pouring, because the existence of the slope of the pitched roof, the factor of the dead weight of the concrete must be considered, the order is reasonable and the concrete pouring can be ensured to be even; secondly, slump control of concrete, time control and quality control of concrete vibration, concrete construction and maintenance quality, integrity of concrete surface, crack control and the like are all difficulties directly related to the final construction effect.
In view of the above disadvantages, the structure of the embodiment solves the following problems:
1. the slope roof construction difficulty is higher, but the professional quality of some constructors in the actual construction process is lower, and even the actual construction management capacity of some design and construction managers is lower. Because constructors do not have a strict qualification admission system, a lot of actual experiences are insufficient, and personnel with insufficient professional literacy can also directly participate in construction, the personnel have insufficient experiences on related site construction, some construction details are not concerned in place, the quality control strength of the details is insufficient, the construction is easy to have the condition of quality hidden danger, and the influence of the hidden danger on the sloping roof is huge. The invention completely avoids the construction on the high sloping roof, and the roof can be constructed on the flat ground in a factory, thus completely avoiding the quality problem caused by the lack of professional literacy of constructors.
2. The form and the buttresses must have sufficient load bearing capacity, rigidity and stability. The slope construction is easy to be unstable, the required stability is higher, the materials for the template and the supporting roof are required to meet the material requirements, and the self weight of newly poured concrete and the load generated in the construction process can be reliably borne. The design of the template and the support thereof is in accordance with relevant special regulations, the template installation must be firm and flat, the thickness of the concrete plate is influenced if the flatness is poor, the self weight and the bearing capacity of the plate are influenced if the thickness is uneven, but the control difficulty of the construction sites of the sloping roof is higher, and the problems existing in the sites can be solved by the invention.
3. The leakage of the slurry due to the overlarge slab joints is also one of the reasons for reducing the quality of the concrete slab of the sloping roof, and the slurry leakage is easily caused because all the templates are inclined and the problems of uneven slab joint, unfirm template fixation and the like frequently occur in the formwork supporting process.
4. Different from a plane plate, the inclined plane plate can not bind hole reinforcing steel bars in a plum point mode, and each intersection point must be completely fastened to prevent the reinforcing steel bars from displacing due to falling of the dead weight of concrete during pouring, which is one of the difficulties in field construction of the sloping roof.
