Abstract
The utility model relates to a one-way stop valve used for concrete jacking and pouring, comprising a column pipe and an adjustor arranged in the column pipe; the adjustor comprises: a round baffle plate and a screw rod which is arranged along the radial direction of the baffle plate and is integrated with the baffle plate; an upper end and a lower end of the screw rod stretch out of the column pipe and are fixed at the outer pipe wall of the column pipe through a rubber washer and a limiting nut; the top of the screw rod is provided with a closer used for controlling the rotation of the baffle plate; one end of the column pipe is provided with a flange used for connecting a pump pipe, and the other end of the column pipe is used for welding with a hole at steel pipe column. Under the role of the pump pressure, the concrete flows into the steel pipe column through the pump pipe and the one-way stop valve. The valve presents closing state during using, and does not have leakage problems; therefore, the construction is convenient, safe and reliable. After the concrete pump completes the jacking and pouring, the pump pressure is controlled for 2-3 minutes, and then the one-way stop valve is closed, and the pump pipe is transferred to another steel pipe column to pour.
Description
Technical field
The utility model relates to the valve body field, specifically is that a kind of concrete lift-up is built and used unidirectional stop valve.
Background technology
Concrete filled steel tube jacking casting craft is exactly to open a hole more bigger than carrier pipe on bottom (highly the be convenient to construction be advisable) tube wall at steel pipe column, be attached thereto with the outlet of carrier pipe concrete pump, concrete is injected in the steel pipe column by carrier pipe continuously by pump pressure, fills with concrete in pipe.Its basic characteristics are:
(1) need not to set up height scaffolding, reduce work high above the ground and labour intensity, operate more handy and safe.
(2) concreting speed is fast, does not waste concrete.
(3) steel pipe is good compression member, and its tube wall still is rational anti-side pressure template, can save the artificial and material of formwork, form removal during the construction concrete.
(4) steel pipe is good cage of reinforcement and stiffness load-bearing skeleton, can simplify construction technology in the construction, save scaffold, reduction of erection time, minimizing construction land tenure.
(5) concrete construction need not to vibrate, and relies on jacking extruding nature closely knit.
For preventing that concrete refluxes when removing carrier pipe, need on the connection short tube, a fluid stopping device to be set, generally adopt flashboard type.Its weak point is: build in the process in the concrete pumping jacking, the flashboard seam easily leaks gas, and causes its safety and reliability lower.
The utility model content
The technical problems to be solved in the utility model provide a kind of simple in structure, convenient construction, safety and reliability preferably concrete lift-up build and use unidirectional stop valve.
For solving the problems of the technologies described above, the utility model provides a kind of concrete lift-up to build and has used unidirectional stop valve, and it comprises: column jecket and the adjuster of being located in this column jecket; Adjuster comprises: circular baffle plate and radially be provided with and constitute the screw rod of one with baffle plate along baffle plate; The upper and lower end of screw rod stretches out column jecket, and is fixed on by rubber washer and stop nut on the outer tube wall of column jecket; The top of screw rod is provided with and is used to control the closer that baffle plate rotates.
Further, described column jecket one end is provided with the flange that is used to connect pump line, the column jecket other end be used for steel pipe column on hole be weldingly connected.Under the effect of pump pressure, concrete flows into steel pipe column through pump line and unidirectional stop valve.
For guaranteeing the rigidity of baffle plate, the central authorities of described baffle plate are provided with respectively the reinforcing rib that welds mutually with baffle plate and screw rod.
The diameter of described circular baffle plate is than the little 0.4-0.6cm of caliber of column jecket, thereby both guaranteed the flexibility that baffle plate rotates, and can prevent when unidirectional stop valve is closed that again concrete from refluxing.
The utlity model has positive effect: when (1) concrete lift-up of the present utility model is built and used with unidirectional stop valve, externally be closed state, so there is not the problem of gas leakage, it is more convenient, safe and reliable therefore to construct.After end was built in the concrete pumping jacking, control pump pressure 2～3 minutes by rotating the closed unidirectional stop valve of closer, was that pump line is transferred to another root steel pipe column and built with elephant trunk then.Treat can excise unidirectional stop valve from steel pipe column after core concrete intensity reaches 70%, repair welding hole tube wall polishes, touch-up paint.(2) adopt concrete lift-up of the present utility model to build and carry out the jacking pouring construction, simplified construction technology, save labour cost with unidirectional stop valve, reduced the input of circulation material, economical with materials has reduced construction land tenure, can guarantee workmanship, shorten the construction period simultaneously.
