Abstract
The invention relates to a cast-in-place concrete polystyrene foam combination platform construction method, which comprises the following steps of: pretreating polystyrene foam blocks, installing the polystyrene foam blocks, and pouring the concrete. The method is characterized in that: the step of pretreating the polystyrene foam blocks is to coat a fireproof reinforced layer at the peripheries of the polystyrene foam blocks; the step of installing the polystyrene foam blocks is to fix the polystyrene foam blocks between an upper reinforcement fabric and a bottom reinforcement fabric, form a gap between adjacent polystyrene foam blocks, arrange fixed cushion blocks between the bottoms of the polystyrene foam blocks and the bottom reinforcement fabric, and arranging anti-floating cushion blocks between the polystyrene foam blocks and the upper reinforcement fabric; and the step of pouring the concrete is to pour the concrete with 2/3 of the rib height, directly vibrate rib beam concrete by using a vibrating spear until a concrete sinking phenomenon does not occur to ensure that the concrete permeates and fills the lower spaces of the polystyrene foam blocks, and then pour the needed concrete while vibrating after the bottom layer is vibrated to be compact.
Description
Technical field
The present invention relates to building field, relate in particular to a kind of cast-in-situ concrete polystyrene foam combination platform construction method.
Background technology
The load of existing cast-in-situ concrete polyphenyl foam combined platform major project is big, and the comprehensive cost height is a little less than the anti-seismic performance, standard width of a room in an old-style house span is little, and heat preservation and insulation is poor, the constructional difficulties complexity, the impaired meeting of interspersed block of pipeline simultaneously pours into wherein concrete, a little less than the bending resistance anti-crack ability of platform floor.
Summary of the invention
The technical solution used in the present invention is:
A kind of cast-in-situ concrete polystyrene foam combination platform construction method, comprise polyphenyl foam piece pre-treatment step, polyphenyl foam piece step and fluid concrete step are installed, it is characterized in that described foam block pre-treatment step is: at the peripheral fire prevention enhancement Layer that coats of polyphenyl foam piece; Described installation polyphenyl foam step is: the polyphenyl foam piece is fixed between top mat and the bottom layer of the reinforcing steel net, leave the gap between the adjacent polyphenyl foam piece, between polyphenyl foam piece bottom and bottom layer of the reinforcing steel net, fixedly cushion block is set, the anti-floating cushion block is set between polyphenyl foam piece and top mat; Described fluid concrete step is to inject the high concrete of 2/3 rib earlier, there is not sinkage with vibrating head girt strip concrete to the concrete that directly vibrates, make the concrete infiltration and fill up side space under the polyphenyl foam piece, the required concrete that and then reinjects behind the bottom vibration compacting vibrates simultaneously.
The particle diameter of coarse aggregate is less than 15mm in the described concrete, and slump 〉=160mm.
The advantage of name of the present invention is: construction is rapid, and platform bending resistance anti-crack ability is strong.Compare with common job practices: save concrete 30%～40%, Application Prospect is extensive.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Description of drawings
Fig. 1 is a kind of cast-in-situ concrete polyphenyl foam combined platform.
The specific embodiment
As shown in Figure 1, a kind of cast-in-situ concrete polystyrene foam combination platform construction method of the present invention, comprise polyphenyl foam piece pre-treatment step, polyphenyl foam piece step and fluid concrete step are installed, the foam block pre-treatment step is: smash in order to make polyphenyl foam piece 7 following concrete watering, and guarantee its density, polyphenyl foam piece 7 bottoms are prefabricated into sphere, are the polyphenyl foam piece 7 peripheral fire prevention enhancement Layers 1 that coat of sphere in the bottom; The polyphenyl foam step is installed is: polyphenyl foam piece 7 is fixed between top mat 5 and the bottom layer of the reinforcing steel net 6, leave gap 8 between the adjacent polyphenyl foam piece 7, fixedly cushion block 4 is set between polyphenyl foam piece 7 bottoms and bottom layer of the reinforcing steel net 6, between polyphenyl foam piece 7 and top mat 5, anti-floating cushion block 3 is set; The fluid concrete step is to inject earlier the high concrete of 2/3 rib, does not have sinkage with vibrating head girt strip concrete 2 to the concrete that directly vibrates.
