Scope, (i.e. catch pit bar-mat reinforcement, including catch pit reinforcement net 1 and bottom are fixed with Steel bar rack 2 to precast reinforced net
Catch pit plate face bar-mat reinforcement 3) blanking with arrangement, Steel bar rack 2 design with arrangement, bar-mat reinforcement suspension hook design with checking computations, reinforcing bar
Net lifting checking computations etc..Wherein need to consider reinforcing bar colligation difficulty in tower crane Lifting Capacity, catch pit, entirety bar-mat reinforcement is pre- in hole
System, precast reinforced net and periphery bar connecting, bar-mat reinforcement moulding bed make the aspects such as complexity and consider precast reinforced net
Scope；Precast reinforced material off the net includes precast reinforced Cutting calculation, reinforcing bar spatial arrangement etc. with arrangement, and sets up precast reinforced net
Threedimensional model etc.；Meet stablizing and force request for precast reinforced net itself, carry out the design of Steel bar rack 2 and arrangement；Additionally,
To meet bar-mat reinforcement integral hoisting demand, need to shift to an earlier date and additionally arrange suspension hook in the Deepen Design stage, carry out bar-mat reinforcement lifting checking computations,
To meet bar-mat reinforcement lifting rigidity and strength demand, additional bar etc. need to be additionally arranged.
Step 2, the catch pit prefabricated processing of precast reinforced net 100, the catch pit bar-mat reinforcement includes catch pit reinforcement
Net 1 and bottom are fixed with the catch pit plate face bar-mat reinforcement 3 of Steel bar rack 2.Bar-mat reinforcement processing include bar-mat reinforcement moulding bed design and
Make, bar-mat reinforcement moulding process, bar-mat reinforcement precision controlling etc..Wherein to meet the prefabricated demand of catch pit bar-mat reinforcement, need to be in project
Scene or processing factory design and make a bar-mat reinforcement high accuracy and make moulding bed, and moulding bed profile and size need to be according to precast reinforced nets
Profile and size determine.First carry out setting up bar-mat reinforcement moulding bed at project scene or processing factory, carry out the prefabricated of reinforcement net
Processing, such as Fig. 2；Steel bar rack 2 is set up, the prefabricated processing of catch pit plate face bar-mat reinforcement 3 is carried out, as shown in Figure 3.Additionally, in steel
In muscle net process, the machining accuracy of moulding bed, the blanking of single steel bar and installation accuracy etc. need to be strictly controlled.
Step 3, the precast reinforced layering of net 100 lifting of catch pit and assembly：Catch pit reinforcement net 1 is first lifted, then is hung
The portion of loading is fixed with the catch pit plate face bar-mat reinforcement 3 of Steel bar rack 2 so that catch pit reinforcement net 1 and catch pit plate face steel
Muscle net 3 is set in turn in from the bottom to top in catch pit.Specifically, the precast reinforced layering of net 100 lifting of catch pit and assembly, including
Bar-mat reinforcement Hoisting Program determine, catch pit reinforcement net 1 be accurately positioned in catch pit, catch pit reinforcement net 1 with collection
Puddle plate face bar-mat reinforcement 3 is assembled.Wherein need to determine the size and weight of catch pit baseplate reinforcing bar net 1 according to tower crane Lifting Capacity in advance
Amount, is carried out with taking into account Lifting Capacity and as far as possible prefabricated principle；Precast reinforced net layering lifting special scheme is formulated, and formulates phase
Emergency measure answered etc., first lifts reinforcement net, as shown in Figure 4,5, catch pit plate face bar-mat reinforcement 3 and lower rebar is lifted afterwards
Support 2, as shown in Figure 6,7.
Preferably, be layered in prefabricated method of construction in above-mentioned basement bottom board catch pit bar-mat reinforcement, the step 3 it

The inner setting of shaped steel, each level right angle side shaped steel in every group of bracing frame is connected by a pair of parallel bar steel.
9. a kind of basement bottom board catch pit bar-mat reinforcement is layered prefabricated method of construction, it is characterised in that using such as claim 1-8
Basement bottom board catch pit bar-mat reinforcement layering precast construction described in middle any one, comprises the steps：
Step one, the design of catch pit bar-mat reinforcement；
Step 2, the catch pit prefabricated processing of precast reinforced net, the catch pit bar-mat reinforcement include catch pit reinforcement net and
Bottom is fixed with the catch pit plate face bar-mat reinforcement of Steel bar rack；
Step 3, the precast reinforced net layering lifting of catch pit and assembly：Catch pit reinforcement net is first lifted, then lifts bottom and consolidated
Surely there is the catch pit plate face bar-mat reinforcement of Steel bar rack so that catch pit reinforcement net is with catch pit plate face bar-mat reinforcement from the bottom to top
It is set in turn in catch pit；
Step 4, catch pit reinforcement net is connected with catch pit peripheral floor reinforcement by root is corresponding, by catch pit plate
Face bar-mat reinforcement connects with catch pit peripheral floor plate face reinforcing bar by root is corresponding；
Step 5；Pour the underplate concrete with catch pit.
10. basement bottom board catch pit bar-mat reinforcement as claimed in claim 9 is layered prefabricated method of construction, it is characterised in that institute
Before stating step 3, control line is drawn in four corners of the bed course or brick loose tool for planning to build catch pit, utilized in hoisting process
The angular alignment bed course upper control line of bottom four of catch pit reinforcement net, completes catch pit reinforcement net and accurately enters hole positioning
Work.
