The structure of the embodiment is mainly made aiming at the defects of the prior art, and the prior art usually adopts the process of setting up a scaffold, supporting a template, binding steel bars and pouring concrete, and has the following defects:
1. In the construction process of the cast-in-situ reinforced concrete sloping roof, various side lines and sloping lines are more, most of the side lines and sloping lines are mutually inserted and staggered, but for the sloping roof, the straight sloping lines and the flat sloping surfaces are the pursued targets of building modeling. The construction support of the cast-in-situ reinforced concrete sloping roof is required to be designed for supporting horizontal thrust by an inclined plane on the basis of standard requirements, and the capability of supporting horizontal thrust and vertical thrust is improved, so that the difficulty of design is increased intangibly.
2. The sloping roof is in most cases a symmetrical slope, while the internal beam is usually trapezoid, arc-shaped, etc. in cross section, so the shape of the steel bar is the same as the beam. The special beam has extremely high requirement on the steel bar bundling, so how to improve the steel bar bundling and the processing quality becomes a key factor influencing the engineering quality. The present building design construction is often the building form in large space, and this just leads to the span of building beam slab itself just to be big, and the thickness of board is often also great, just needs double-deck two-way to carry out the design arrangement of inboard reinforcing bar, only carries out the design of reinforcing bar protective layer strictly, and the production of concrete slab shrink crack can be avoided to the maximum degree to strictly control protective layer thickness. Therefore, the steel bar engineering is also one of key points of difficult control of the construction quality of the cast-in-situ concrete sloping roof.
3. The concrete construction must consider the construction pouring sequence, because the existence of slope roof gradient, the factor of the dead weight of the concrete must consider, the order is rational to guarantee the uniformity of concrete pouring; and then slump control, concrete vibrating time control and quality control, concrete construction maintenance quality, concrete surface integrity, crack control and the like are all difficulties directly related to the final construction effect.
Aiming at the defects, the problems solved by the structure of the embodiment are as follows:
1. The construction difficulty of sloping roof is great, but the professional quality of partial constructors in the actual construction process is lower, and even the actual construction management capability of some designs and construction managers is lower. Because constructors do not have a strict qualification admittance system, a plurality of practical experiences are insufficient, and the constructors with insufficient professional literacy can directly participate in the construction, the constructors have insufficient experience on the relevant site construction, attention on construction details is not in place, the quality control force of the details is insufficient, the construction is easy to generate the condition of hidden quality hazards, and the hidden quality hazards have a huge influence on sloping roofs. The invention completely avoids construction on the high slope roof, the roof can be used for construction operation on the flat ground of a factory, and the quality problem caused by insufficient professional literacy of constructors is completely avoided.
2. The form and roof must have sufficient load-bearing capacity, rigidity and stability. The inclined plane construction is extremely easy to be unstable, the required stability is higher, the templates and the supporting materials are required to meet the material requirements, and the dead weight of the newly poured concrete and the load generated in the construction process can be reliably born. The design of the template and the support thereof should conform to the relevant special regulations, the installation of the template must be firm and smooth, the poor flatness will affect the thickness of the concrete slab, the uneven thickness affects the dead weight and the bearing capacity of the slab, but the difficulty of controlling the construction sites on sloping roofs is large, and the invention can solve the problems existing on the sites.
3. Too large slab joint leakage is one of the reasons for reducing the quality of the concrete slab on the sloping roof, because all the templates are inclined, the problems of uneven slab joint, unstable template fixation and the like frequently occur in the formwork supporting process, and the leakage is easy to cause, and the invention can completely solve the problems.
4. Unlike planar plate, the inclined plate can not be tied firmly at all intersecting points, so that the displacement of the steel bar caused by the falling of the dead weight of the concrete during pouring is avoided, and the inclined plate is one of difficulties in site construction of sloping roofs.
