Size is 300mm × 100mm × 200mm, and the size of remaining tongue and groove 13 is 600mm × 100mm × 200mm, the diameter in hole 12
For 120mm, the spacing between hole 12 is 130mm, can be adjusted according to actual conditions.
B, tongue and groove hollow pre-fabricated panels 1 are lifted, setting is spaced between tongue and groove hollow pre-fabricated panels 1.
In the present embodiment, tongue and groove hollow pre-fabricated panels 1 are lifted by hoist engine.With sectional dimension for 4.8m × 1.2m ×
For the tongue and groove hollow pre-fabricated panels 1 of 0.2m, the weight by calculating every piece of tongue and groove hollow pre-fabricated panels 1 is about 2.4t, according to construction
Environmental condition is general to be lifted using two hoist engines.Tongue and groove hollow pre-fabricated panels 1 are lifted to wall, beam according to design requirement
Wall is closed in top specified position, the end of tongue and groove hollow pre-fabricated panels 1 of beam is beaten at wall, Liang Shang, the end of tongue and groove hollow pre-fabricated panels 1
Head beats the length on wall, beam and is not less than 60mm, and the lateral clearance of adjacent two pieces of tongue and groove hollow pre-fabricated panels 1 is not less than 300-
500cm, to ensure the cross sectional dimensions of subsequent well word Cast-in-situ Beam 2.
C, scaffold is set up below the gap of tongue and groove hollow pre-fabricated panels 1, and in the top installation form of scaffold, is
The construction of follow-up well word Cast-in-situ Beam 2 is prepared.
Because in stepb, the gap of tongue and groove hollow pre-fabricated panels 1 is 300-500cm, so being using double-pole scaffold
It can meet the requirements, in the present embodiment, scaffold longitudinal pitch is preferably 900-1200cm, and step pitch is preferably 600-900cm, foot
Hand cradle parameter can be adjusted according to actual loading situation.Template uses bamboo slab rubber or plank.
D, reinforcing bar of the binding for making well word Cast-in-situ Beam 2, and the reinforcing bar bound is positioned between hollow pre-fabricated panels
In gap.
As shown in Fig. 2, well word Cast-in-situ Beam 2 includes cast-in-place crossbeam 3 and cast-in-place longeron 4；The main function of cast-in-place crossbeam 3 be by
Two pieces of prefabricated board ends link together, and the width of cast-in-place crossbeam 3 is not less than 120mm.Otherwise, backing plate or bent cap should be set to increase
Add the width of cast-in-place crossbeam 3.The effect of cast-in-place longeron 4 is by the side connection of two pieces of tongue and groove hollow pre-fabricated panels 1, and width is
300-500mm, that is, when arranging tongue and groove hollow pre-fabricated panels 1, between tongue and groove hollow pre-fabricated panels 1 and tongue and groove hollow pre-fabricated panels 1
Gap pulls open a certain distance, generally 300-500mm.Cast-in-place crossbeam 3 includes crossbeam mixed mud main body 31, several mixed set on crossbeam
The small stirrup 33 of crossbeam and the big stirrup of crossbeam of crossbeam longitudinal reinforcement 32 and binding crossbeam longitudinal reinforcement 32 in soil main body 31
34, the small stirrup 33 of crossbeam and the big stirrup 34 of crossbeam are for bundling crossbeam longitudinal reinforcement 32, and the small stirrup of crossbeam 33 is generally according to construction
It is required that be set as the three-level steel wire of a diameter of 4-8mm, the spacing of the small stirrup of crossbeam 33 is 150-200mm；The big stirrup 34 of crossbeam is right
Tongue and groove 13 is answered to be arranged, the parameter of the small stirrup of the big stirrup 34 of crossbeam and crossbeam 33 is identical, and only the big stirrup of crossbeam 34 becomes large-sized, this
It is since the tongue and groove 13 of tongue and groove precast hollow slab causes, in addition, the big stirrup of crossbeam 34 will also be exposed at the prefabricated board at tongue and groove 13
The end of longitudinal reinforcement 15 is bundled with crossbeam longitudinal reinforcement 31, for enhancing well word Cast-in-situ Beam 2 and tongue and groove hollowcore precast
The connection effect of plate 1.Cast-in-place longeron 4 includes longeron mixed mud main body 41, several longerons in longeron mixed mud main body 41
The longeron stirrup 43 of longitudinal reinforcement 42 and binding longeron longitudinal reinforcement 42；The intensity mounting design of longeron mixed mud main body 41
Depending on calculating, it is not less than the intensity of prefabricated board mixed mud main body, generally takes C30, the quantity of crossbeam longitudinal reinforcement 32 is four.Two
Two is setting up and down, and longeron longitudinal reinforcement 42 generally uses the three-level steel bar of a diameter of 10-14mm；Other four longeron longitudinal reinforcements
42 pass through the end of prefabricated board longitudinal reinforcement 15 to connect the U-shaped structure to be formed, and can enhance well word Cast-in-situ Beam 2 in this way and tongue and groove is empty
The connection effect of heart prefabricated board 1；43 general installation constitution of longeron stirrup requires the grade III steel for being set as a diameter of 4-8mm, longeron
The spacing of stirrup 43 is 50-100mm.The reinforcing bar bundled in summary is made of crossbeam longitudinal reinforcement 32 and longeron longitudinal reinforcement 43
E, consolidation process is carried out to detail treatment；
In step e, it includes as follows to detail treatment reinforce:Stirrup is carried out to the larger position of joints to add
It is close；When the transverse width of well word Cast-in-situ Beam 2 is inadequate, take setting under backing plate or beam is arranged under wall to emit the measure of beam being solved
Certainly；The end for blocking the hole 12 of tongue and groove hollow pre-fabricated panels 1, to prevent in mixed mud run-in-hole 12.
F, as shown in figure 3, pouring mixed mud, the reinforcing bar phase of mixed mud and binding toward the gap between tongue and groove hollow pre-fabricated panels 1
In conjunction with well word Cast-in-situ Beam 2 is formed, final well word Cast-in-situ Beam 2 connects each tongue and groove hollow pre-fabricated panels 1 and forms floor.
The floor construction method that above-mentioned tongue and groove hollow pre-fabricated panels 1 and well word Cast-in-situ Beam 2 are combined is simple for process, and template is used
Amount less, environmental pollution it is small, constructing operation is simple, and by floor made from this method because be by tongue and groove hollow pre-fabricated panels 1
It is combined into well word Cast-in-situ Beam 2, so the advantages of having gathered hollow pre-fabricated panels and cast-in-place concrete board, comprehensive performance is strong.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
