Therefore known built-in type builder's jack retainer ring there are problems that above-mentioned a variety of inconvenience and.
The content of the invention
The purpose of this utility model, it is to propose a kind of safe and reliable detachable builder's jack retainer ring.
To achieve the above object, technical solution of the present utility model is：
A kind of detachable builder's jack retainer ring, suitable for aluminum alloy pattern plate Fast-dismantle system, including Π shapes round steel and PVC sets
Pipe, it is characterised in that：
The Π shapes round steel is made by diameter >=18mm round steel, and both ends is set threaded screw rod, equipped with packing ring and spiral shell
It is female；During Π shape round steel use states, two through holes that both ends screw rod is penetrated in same steel liner plate, and with packing ring and nut check
Retainer ring is formed, for being fixedly connected with builder's jack；
Two PVC sleeve pipes are provided, the PVC sleeve pipes are inserted among the both ends screw rod of Π shape round steel in advance respectively, and by PVC
Sleeve pipe pre-embedding enters in concrete.
Detachable builder's jack retainer ring of the present utility model can also be using following technical measures come further
Realize.
Foregoing detachable builder's jack retainer ring, wherein the width root between the both ends screw rod of the Π shapes round steel
Determined according to the width of I-steel used.
Foregoing detachable builder's jack retainer ring, wherein the mantle fiber length of the both ends screw rod of the Π shapes round steel is not
Less than 200mm, ensure that nut tightens the exposed 50mm of rear sleeve screw rod.
Foregoing detachable builder's jack retainer ring, wherein the nut fastens for double nut.
Foregoing detachable builder's jack retainer ring, wherein the steel liner plate is the rectangular steel plates thick no less than 5mm,
Rectangular steel plates size is per more than back gauge through hole 50mm, and through-hole diameter is preferably bigger 1-2mm than round steel diameter.
Foregoing detachable builder's jack retainer ring, wherein the nut is high-strength nut.
After adopting the above technical scheme, detachable builder's jack retainer ring of the present utility model has advantages below：
1st, retainer ring apparatus structure is simple, easy to make；
2nd, improve builder's jack and set up efficiency, save manually, construction is fast, securely and reliably；
3rd, material, green, repeatable to utilize, reduction engineering cost are saved.
Brief description of the drawings
Fig. 1 is the detachable builder's jack retainer ring structural representation of the utility model embodiment；
Fig. 2 is the detachable builder's jack retainer ring use state diagram of the utility model embodiment.
In figure：1 Π shape round steel, 2PVC sleeve pipes, 3 steel liner plates, 4 nuts, 5 I-steel, 6 concrete.
Embodiment
With reference to embodiments and its accompanying drawing illustrates further to the utility model.
Embodiment 1
Detachable builder's jack retainer ring of the present utility model, justify suitable for aluminum alloy pattern plate Fast-dismantle system, including Π shapes
Steel and PVC sleeve pipes.
Referring now to Fig. 1, Fig. 1 is the detachable builder's jack retainer ring structural representation of the utility model embodiment
Figure.As illustrated, the Π shapes round steel 1 is made by diameter 18mm round steel, both ends is set threaded screw rod, and screw rod is equipped with pad
Circle and nut 4；During Π shape 1 use states of round steel, two through holes that both ends screw rod is penetrated in same steel liner plate 3, and use packing ring
Locked with nut 4 and form retainer ring, for being fixedly connected with builder's jack；The steel liner plate 3 is the rectangle steel thick no less than 5mm
Plate, rectangular steel plates size are per more than back gauge through hole 50mm, and through-hole diameter is preferably bigger 2mm than round steel diameter.The Π shapes
The width of width I-steel 5 used between the both ends screw rod of round steel 1 determines.The both ends screw rod of the Π shapes round steel 1
Mantle fiber length is no less than 200mm, ensures to tighten exposed more than the 50mm of rear sleeve screw rod with double high-strength nut fastenings.
Two PVC sleeve pipes 2 are provided, the PVC sleeve pipes are inserted among the both ends screw rod of Π shape round steel in advance respectively, and will
PVC sleeve pipe pre-embeddings enter in concrete 6.
Embodiment 2
The application method of detachable builder's jack retainer ring of the present utility model：
The position of builder's jack is installed according to the design needs, it is predetermined to fix same root connection scaffold with two sets of retainer rings
I-steel, in advance by the Transducers Embedded in Concrete of PVC sleeve pipes 2 for the retainer ring arranged before and after two, the mantle fiber of Π shapes round steel 1 during installation
Both ends are pasted with adhesive plaster, can prevent screw thread from by Concrete contamination, causing nut installation difficulty, can also prevent concrete grout from filling
Enter space between round steel and pvc pipe to result in blockage, avoid later dismounting inconvenient for use.It is inserted in more than slab thickness 20mm in outside
