For concrete floor slab placement, what emphasis was concentrated mainly on template builds mode.Conventionally employed method has the technique more normal
The full hall scaffold of rule successively pours or precast floor slab concreting, but full hall scaffold is successively poured due to successively to take
And if pour, each layer has the process of formwork form removal, and the duration is time-consuming longer.And for the method for precast floor slab, although being not required to
Form removal is repeatedly taken, but needs to set up angle steel and is laid with floor support plate, vertical transport difficulty is bigger, and cost is relatively high.
Still an alternative is that on the basis of existing structure angle steel and steel I-beam is set to be used as shuttering supporting, herein on basis
Steel form is laid with, then using steel form as job platform, using movable Scaffold, one layer is continued up and sets up angle steel and I-shaped
Girder steel, and so on.Although steel form speed of application is very fast and part girder steel will be left in after pour the inside of beam, the knot of beam is poured to after
Structure is beneficial, but each component vertical transport difficulty of this method is big, will also destroy part steel form, and needs to set up fixed and remove
A large amount of angle steel, I-steel, thus will generate more expense, cost is higher.

After the pouring molding of side, tube drawing forms reserving hole channel.
(2) screw side pole is inserted by reserving hole channel in the concrete poured on both sides, and utilizes and improve LM type screws
Side pole anchorage is anchored, and reinforcing bar is accessed on both sides respectively by butt joint.
(3) rotated since the reinforcing bar at both ends is inconvenient by anchoring, using positive and negative threaded ferrule to both sides bar connecting
It draws, changes reinforcement stresses (it is made to generate certain pre-tensile stress).
(4) welded reinforcement truss mould plate by the use of the reinforcing bar with pre-tensile stress as the top boom of girder system, holds it
By the weight of template；The template uses pre-manufactured steel board.
(5) concreting is completed.
The present invention has the advantages that compared with the prior art：
1st, access and anchoring are provided to pour the reinforcing bar at floor for after by the mode of pre-buried anchorage and pipeline, have it is low into
Originally the characteristics of short, is taken, the step using the time used in bar planting and cumbersome specialty can be not only reduced, also avoid simultaneously
The fatigue strength loss hidden danger of chisel reserved steel bar, has apparent economy and convenience.
2nd, by using the sleeve connection of positive and negative screw-thread both sides reinforcing bar is made to generate certain tensile stress and does steel afterwards to balance
The compression (being similar to prestressing force) caused by the reinforcing bar of top boom is served as during muscle truss mould plate.It no longer needs to set up others such as
The extra support of angle steel, I-steel etc..Greatly reduce the workload of construction personnel.
3rd, due to the method template set up dependence be this layer of reinforcing bar pre-tensile stress, it is possible to construction in layer, nothing
Maintenance must be waited, can realize rapid construction.
4th, the present invention is economical and practical, and simple in structure, stress is clear and definite, and method is easy to operate, strong applicability.
