Embodiment Construction

[0034] The following is attached Figure 1-3 The application is described in further detail.

[0035] The embodiment of the present application discloses a construction method for a long-sized cantilevered floating slab. refer to figure 1 , figure 2 and image 3 A construction method for a long-dimension cantilevered floating slab comprises the following steps:

[0036] S1. Positioning: According to the structural construction drawing and architectural construction drawing, determine the size and position of the cantilevered floating slab, and carry out plane setting out and elevation checking, and complete the ground processing of the cantilevered floating slab's reinforcement and formwork.

[0037] S2. Set up the support system: pour the concrete of the top 5 wall columns first, then complete the construction of the non-overhanging formwork support system and the non-overhanging roof 4 formwork, and then set up the formwork support frame 7 of the cantilever floating sla...

Abstract

The invention relates to a long-size cantilever floating plate construction method, and relates to the technical field of building construction. The method comprises the four steps of positioning, supporting system erecting, pouring and supporting system dismantling. In the pouring step, a cantilever floating plate is poured twice, firstly, a reversed beam and a wall plate are poured, after the reversed beam and the wall plate are initially set to reach 70% strength, the floating plate is poured, and when the floating plate is poured, concrete is poured from outside to inside. The method has the effect of sharing the weight of the floating plate through the reversed beam and the wall plate, the stability of a formwork supporting frame can be ensured, the load requirement of the formwork supporting frame is lowered, the difficulty of long-size cantilever floating plate construction is lowered, the cost of long-size cantilever floating plate construction is reduced, and the construction period of long-size cantilever floating plate construction is shortened.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for long-sized cantilevered floating slabs. Background technique [0002] At present, with the rapid development of economic construction and urbanization, high-rise or super high-rise buildings with different shapes are rapidly rising one after another in large and medium-sized cities. The roof is cantilevered out of the building plane by means of high-altitude and large cantilever, and a long-sized cantilever floating board is built, making it a landmark landscape of urban architecture. In this design, the height of the cantilevered part from the ground is usually more than 40m, and the length of the cantilevered part is large, making the building more magnificent, three-dimensional and majestic. At the same time, these unique designs have also brought various difficulties to the construction of the building. The construction span is large, ...
