Description
Technical field
It the utility model is related to the visual plant device used on town road bridge and house construction engineering, suitable steel pipe column
With tubular arch pumping concrete construction.
Background technology
In town road bridge and house construction engineering are built, steel pipe column or tubular arch slightly expanded concrete i.e. in steel pipe column or
Filling slightly expanded concrete, the composite construction that two kinds of combinations of materials of different nature are integrally formed in tubular arch.The spy of steel
Property be that intensity is high, there is elastoplasticity；Concrete has preferable anti-compression property, but tensile property is poor.The two is combined, and can make coagulation
Soil is in lateral spacing pressured state, and its compression strength can significantly improve, simultaneously because the effect of fill concrete, it is steady to improve tube wall
Qualitative and resistance to overturning, so as to substantially increase the bearing capacity of structure, impact resistance ability, the Confinement effect of steel pipe carries significantly
The high plastic property of concrete so that the weakness of concrete, particularly Brittleness of High Strength Concrete is overcome.Steel pipe is in itself again
Template and support can not be just needed substantially as the template of resistance to side pressure, during construction.
Steel pipe inner concrete filling using from arch springing to vault or from post bottom to capital continuously be pumped jacking pour in down a chimney apply
Work technique, opened exactly in the arch springing side wall of tubular arch or on Steel Pipe Column downside wall one it is more bigger than concrete delivery pipe caliber
Charging aperture, tubular arch across top set steam vent, with the short tube with stop valve by the outlet and charging of concrete pump
Mouth connection, slightly expanded concrete are continuously pumped into tubular arch and steel pipe column by being pumped by delivery pipe, until being filled in pipe mixed
Solidifying soil.Therefore a short tube with stop valve must be designed.
Utility model content
Technical problem to be solved in the utility model is：Using simple several pieces of steel plates, steel pipes, socket building bolt and set
Hoop, is assembled into a simple delivering concrete stop valve.Ensure to destroy under concrete pumping pressure, will not
Unstability and deformation.To consider simultaneously also will not unstability and deformation when carrying.Assembly welding is simple simultaneously, and weight is light and handy, rises
To the effect for preventing concrete from flowing back.
Technical scheme is used by the utility model solves above-mentioned technical problem：The steel plate big using one piece is used as movable steel
Plate, the steel plate small using two pieces weld 4 block welding plates, two pieces of fixations as fixation steel plate between two pieces of small fixation steel plates
Steel plate welds together, and certain hole is stayed between two pieces of small fixation steel plates, may be inserted into big movable steel plate.In two pieces of fixations
Diameter 145mm circular hole is opened on steel plate, internal diameter 125mm concrete pump pipe is respectively welded in the side of two pieces of fixation steel plates,
One end with of concrete pump pipe has the cuff of concrete pump pipe connection.Respectively opened on two pieces of small fixation steel plates two long
320mm, wide 20mm groove, the depth of groove are the thickness of fixation steel plate.Diameter 135mm circular hole and 4 is provided with movable steel plate
Individual diameter 20mm bolt hole.Movable steel plate may be inserted between two pieces of small fixation steel plates, the bolt hole on movable steel plate
The groove being aligned on fixation steel plate, then movable steel plate and fixation steel plate are connected with 4 diameter 18mm socket bolt and nut
Pick up and, when the circular hole of diameter 135mm on movable steel plate is directed at the pump line hole on fixation steel plate, tighten 4 a diameter of 18mm
The nut for socketing bolt, make nut compressing fixation steel plate using the pulling force of bolt, be to socket bolt to move, so as to ensure
Slip will not be produced between movable steel plate and two pieces of fixation steel plates.Now can utilizes concrete stop valve short tube pumped concrete
Soil.After filling concrete terminates, unscrew the nut of 4 bolts, manually movable steel plate pull out distance 135mm with
On, it is possible to the passage of pump line inner concrete is blocked, plays a part of ending concrete, then withdraws pump truck, wait concrete hard
Can be with dismantling concrete stop valve after change.
Compared with prior art, the utility model has the advantage of：Using traditional stop valve, two rows are opened on pump line
Hole, 3 holes are often arranged, after filling concrete terminates, insertion steel carves son in each hole, and this device can not prevent concrete stream completely
Outside outlet pipe, while 6 holes are provided with pump line, concrete easily overflows from 6 holes in pump concrete.And this practicality is new
Type device, a short tube with stop valve, microdilatancy are welded into using simple several blocks of steel plates, several bolts and concrete pump pipe
Concrete is continuously pumped into tubular arch and steel pipe column by short tube of the pump pressure by delivery pipe and with stop valve, until being filled in pipe
Concrete, after filling concrete terminates, it is only necessary to twitch activity steel plate, it is possible to prevent outside concrete effuser.This invention dress
Putting can save manually, and accelerating construction progress is cost-effective.This invention device is used for multiple times by Practical Project, it was demonstrated that can be with
Meet the requirement of intensity, rigidity, stability and globality.
