Reinforced concrete roof laying technology and dedicated vacuum tube

Abstract

The invention discloses a reinforced concrete roof pouring technique and its special vacuum pipe, its pouring method: a, using wood board and steel plate to put up top mould; b, lay reinforced bars in turn and in parallel on the top mould; c, pour concrete to submerge the reinforced bars; d, lay vacuum pipes on the concrete layer in the same direction to the reinforced bars', where each vacuum pipe is between and above two reinforced bard above; e, pour concrete to the designed thickness; f, vibrate tightly the concrete by plate vibrator, plaster and calendar. It adds heat -protection and -insulation performances to the roof, eliminates the pouring and laying of the concrete layer on the top layer of the roof to reduce the dead weight of the roof, combined with the support decompression function of the vacuum pipe on the roof, obviously reduces subsidence degree and crack coefficient of the roof, enhances the quality of the roof and reduces the construction cost of the roof by 20 % above.

Description

technical field [0001] The invention relates to a building construction method of a roof, in particular to a reinforced concrete roof pouring technology and a special vacuum tube thereof. Background technique [0002] In modern building construction, due to the needs and requirements of seismic performance, the load-bearing floors and roofs between floors are integrally poured with reinforced concrete. The specific method of roof pouring is: first use wood and steel plates to support the top formwork, Then lay the steel bars side by side on the top form in sequence. There are side-by-side and cross-network laying of steel bars. If cross-network structure is adopted, iron wires need to be bound and fixed at each intersection of steel bars. After laying the steel bars, pour concrete until the design thickness, and then vibrate with a plate vibrator. After the solidification period, carry out secondary construction, that is, lay perlite or footstone and other thermal insulati...

AI Technical Summary

Problems solved by technology

In addition, due to the poor thermal insulation performance of the reinforced concrete layer, it is necessary to lay a thermal insulation layer

And the insulation layer is installed between the two concrete layers of the roof, so that the roof cannot form an overall structure, and the effect of mutual involvement and supporting decompression cannot be achieved, but it can only increase the compression weight of the lower concrete layer of the roof, making the roof The slump and crack coefficient further increase
