Abstract
Embedded hat type pre-stressed steel pipe concrete component and its secondary position control on-load pressure method of forming, when making concrete filled steel tubular member, appropriate concrete grout is first poured, block is then depressed into design attitude under the control loading of pressure seat in the plane, then block and steel-pipe welding are got up while sealing steam vent.The prestressing force size of concrete filled steel tube is determined by the ratio of volume of concrete and steel pipe volume.In pressure seat in the plane control loading procedure, if block does not have in place also, but the load that forcing press applies has been above prestressing force, illustrates that concrete grout is excessive, it is desirable to reduce grouting.If block is in place, but forcing press load is less than prestressing force, illustrates that concrete grout is few, it is necessary to increase grouting.Second load forming method is the precompression of default concrete filled steel tubular member；Loading Method is controlled with position to be loaded until preliminary dimension to concrete filled steel tubular member；Grouting quantity is adjusted in the loading procedure of second load forming method, when block is pressed onto predeterminated position, the load of forcing press is just preset pressure.
Description
Technical field
The present invention relates to a kind of embedded hat type pre-stressed steel pipe concrete component and its secondary position control on-load pressure method of forming,
Belong to prestressed concrete technology field.
Background technology
It is single at present mostly by pressure grouting concrete filled steel tube preparation method, but due to the mobility of concrete itself
Pure use concrete vibrating mode, one side corner narrow gap is still difficult to fill real, when on the other hand sealing between concrete grout and hush panel
Gap is easier, has caused its actual bearing capacity ratio design load to decrease.
The present invention solves the problem using embedded cap method, and penetration concrete slurry first is slightly more some more than amount of calculation, then with position
Control method control pressure machine is loaded onto the design height of concrete filled steel tubular member, while exhaust of the gas in steel pipe in block
Mouth discharge, in place rear welded still pipe and block seals exhaust outlet simultaneously.Side so can be as far as possible filled under pressure
Angular gap forms pre-stressed steel pipe concrete component, improves the bearing capacity of component.
The content of the invention
Add object of the present invention is to provide a kind of embedded hat type pre-stressed steel pipe concrete component and its control of secondary position
Compression moulding method is carried, the present invention controls lower loading welding block and steel pipe forming with embedded block and pressure seat in the plane, than commonly shaking
Smash method making concrete filled steel tube it is finer and close, be easier to fill corner gap, so as to improve bearing capacity.
To achieve the above object, the technical solution adopted by the present invention is a kind of embedded hat type pre-stressed steel pipe concrete component
And its secondary position control on-load pressure method of forming, hat type pre-stressed steel pipe concrete component is embedded including steel pipe, with steam vent
Embedded block, when making concrete filled steel tubular member, first pours appropriate concrete grout, then block under the control loading of pressure seat in the plane
Design attitude is depressed into, then block and steel-pipe welding are got up while sealing steam vent.The prestressing force size of concrete filled steel tube by
The ratio of volume of concrete and steel pipe volume is determined.In pressure seat in the plane control loading procedure, if block does not have in place also, but pressure
The load that machine applies has been above prestressing force, illustrates that concrete grout is excessive, it is desirable to reduce grouting.If block is in place, but
It is forcing press load less than prestressing force, illustrates that concrete grout is few, it is necessary to increase grouting.
Second load forming method is the precompression of concrete filled steel tubular member default first；Secondly Loading Method is controlled to steel with position
Pipe concrete component is loaded until preliminary dimension；Grouting quantity is adjusted in the loading procedure of last second load forming method, makes lid
When cap is pressed onto predeterminated position, the load of forcing press is just preset pressure.
Compared with prior art, the present invention has the advantages that.
1st, the prestressed concrete filled steel tubular member of accurate satisfaction setting can be manufactured.
2nd, than conventional method making of vibrating concrete filled steel tubular member even compact, gas hole defect are few.
3rd, than the concrete filled steel tubular member high capacity of conventional method making of vibrating.
Brief description of the drawings
Fig. 1 is the steel core concrete column under forcing press after the completion of being in the milk.
Fig. 2 is the steel core concrete column that prosecutor formula in place is issued to design height.
Specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1-2, preset the precompression of steel core concrete column according to demand first, be then more than to being poured into steel pipe
The concrete grout of steel pipe volume, then covers block, now the total height of steel core concrete column L bigger than design height.
The component in making is loaded with displacement-controlled method control pressure machine, as block is moved down, component total height is gradually
Close to design height, the load that forcing press applies also constantly increases.If block does not have in place also, but the load that forcing press applies
Preset pressure is had been above, illustrates that concrete grout is excessive, it is desirable to reduce grouting, repeats bits control loading again removes slurry until block position
Move during for L, forcing press load is preset pressure.Welding block and steel pipe are while sealing exhaust outlet.
If block has been pressed onto position, but forcing press load still less than preset pressure, illustrate that concrete grout is few, it is necessary to increase
Plus grouting.When block displacement is L, forcing press load is preset pressure for re grouting, loading.Welding block and steel pipe are simultaneously
Sealing exhaust outlet.
In position control loading procedure, the gas in steel pipe is discharged by the exhaust outlet in block.
