Embodiment Construction

[0043] see example figure 1 As shown, a foundation pit 2 of a mass concrete floor to be poured is shown in the figure. The foundation pit includes a normal area and a deep pit area 13 in the middle of the foundation pit, and there are 4 water collecting wells and 6 elevator shafts distributed in the foundation pit. .

[0044] see Figure 2-7 As shown, this large-volume concrete floor reinforcement support system includes a floor lower-layer steel bar 1 arranged above the inner bottom formwork of the foundation pit and an inner support steel column 11 supported by the foundation pit that is fixed at intervals and stands on the upper surface of the lower floor steel bar 1, The bottoms of the vertical supports are all centrally and fixedly connected with a bottom connecting plate 31 , and the lower side of the bottom connecting plate 31 is fixedly connected with the upper side of the lower layer reinforcing bars 1 of the bottom plate. A top connecting plate 32 is fixedly connec...

Abstract

The invention relates to a large-volume concrete floor reinforcement supporting system and a construction method thereof. The supporting system comprises a floor lower layer reinforcement, inner supporting steel columns, additional steel columns, first supporting beams and second supporting beams, a platform plate is laid above a horizontal support, and additional supports are fixedly connected between vertical supports. The construction method includes the steps of construction of the lower layer reinforcement, construction of the inner supporting steel columns, construction of the additionalsteel columns, construction of the first supporting beam, the second supporting beam, the additional supports and the like, and then laying the platform plate above the horizontal support. Accordingto the large-volume concrete floor reinforcement supporting system and the construction method thereof, the additional steel columns are connected with the floor lower layer reinforcement, the inner supporting steel columns and the additional steel columns are fixedly connected with the horizontal support, the platform board is installed on the horizontal support so that the platform board can quickly become a binding platform for an upper portion reinforcement, the structure and procedure of laying large-volume concrete cooling cold water pipes in a reinforcement supporting frame body are eliminated, the platform plate is removed after binding the upper reinforcement, and construction is convenient.

Description

technical field [0001] The invention relates to a large-volume concrete reinforcing bar supporting system, in particular to a multi-layer reinforcing bar supporting frame body for the bottom plate of a super high-rise building and a construction method thereof. Background technique [0002] In recent years, with the rapid development of the construction industry, mass concrete has been used more and more widely. The multi-layered pouring of mass concrete will restrict the construction efficiency due to factors such as long curing time and uneconomical amount of steel bars, while the one-time overall pouring of mass concrete has relatively high requirements on construction technology, especially in the case of epithelial steel bars with many layers and arrangements. When it is dense, occupies a large area, weighs a lot, and is far away from the lower reinforcement, the installation speed and stability of the reinforcement support frame directly affect the efficiency of the re...
