Technical scheme: the described a kind of PVC sleeve pipe that is used to make the hole to be provided construction of the utility model; Comprise PVC plastic pipe, standing screw; The length of said PVC plastic pipe is greater than Laminate construction thickness; The sidewall of said PVC plastic pipe has an inclined-plane groove; The both sides, top of said inclined-plane groove have two first recesses; Said PVC plastic pipe port and said first recess are central axis symmetry place and have two second recesses, and said standing screw comprises harness cord, self-tapping screw, nut, plays the keel frame and the passive band steel of pressuring action, and the two ends of said harness cord are fixing with the tail end and the welding of reinforcing bar handle of said self-tapping screw respectively; Said passive band steel passes through fixed by nut on said harness cord with the keel frame that plays pressuring action; Said passive band steel length is less than or equal to the internal diameter of said PVC plastic pipe, and the width between the width between two said first recesses and two said second recesses is identical with the width of the keel frame of said pressuring action, and said standing screw is arranged in the said PVC plastic pipe; The vertical external part of the keel frame both sides of said pressuring action is fastened in said first recess and second recess, and it is inboard that said passive band steel is arranged on the said PVC plastic pipe other end.
Further, the weld of said reinforcing bar handle and said harness cord is unequal to the distance at its two ends.
For the shutoff sleeve pipe; Build when preventing concreting into and influence the hole quality in the sleeve pipe; Also comprise circular cover; Said circular cover diameter is greater than the external diameter of said PVC plastic pipe, and the center of said circular cover has out two different company holes of diameter, and said circular cover passes the said hole that connects through said reinforcing bar handle and is arranged between the keel frame and reinforcing bar handle of said fixation.
According to the job practices that above-mentioned PVC sleeve pipe is made hole to be provided,, each platform hole reserve position is located in advance at first according to the hot-water heating drawing; Before civil engineering base plate muscle was laid, opsition dependent was fixed on said PVC sleeve pipe on the bamboo splint through said self-tapping screw, and builds gland then; After treating concrete setting at last, taking out said support fixation body, is dismountable sleeve pipe toward the said PVC sleeve pipe of inboard extruding.
The utility model compared with prior art, its beneficial effect is: the utility model is said to be used for the PVC sleeve pipe of hole to be provided construction, and spillage of material is less than the steel sleeve pipe, manufacture craft is simple; The maintenance operation is simple; Only note the recovery and the protection of standing screw during use, saved the operation of steel sleeve scaling brush oil, and be difficult for being out of shape because of repeated use; Difficulty of construction is little, saves artificial; This sleeve pipe can change the mode of sleeve pipe caliber to be dismantled, and makes the dismounting time mobility more of sleeve pipe, not restricted because of concrete setting time, has improved work efficiency, has reduced the activity duration of job site.Have advance, applicability, economy, should be widely promoted.
Description of drawings
Fig. 1 is used for the structural representation of the PVC sleeve pipe of hole to be provided construction for the utility model is said.
Fig. 2 is the vertical view of the said PVC plastic pipe of the utility model.
Fig. 3 is the sketch map of the said circular cover of the utility model.
The specific embodiment
Be elaborated in the face of the utility model technical scheme down, but the protection domain of the utility model is not limited to said embodiment.
A kind of PVC sleeve pipe that is used to make the hole to be provided construction; Comprise PVC plastic pipe 1, standing screw; The length of said PVC plastic pipe 1 is greater than Laminate construction thickness; The sidewall of said PVC plastic pipe 1 has an inclined-plane groove 2; The both sides, top of said inclined-plane groove 2 have two first recesses 3; Said PVC plastic pipe 1 port and said first recess 3 are central axis symmetry place and have two second recesses 4; Said standing screw comprises harness cord 5, self-tapping screw 6, nut, plays the keel frame 8 and the passive band steel 9 of pressuring action, and the two ends of said harness cord 5 are fixing with the tail end and 7 welding of reinforcing bar handle of said self-tapping screw 6 respectively, and said reinforcing bar handle 7 is unequal to the distance at its two ends with the weld of said harness cord 7; Said passive band steel 9 is fixed on the said harness cord 5 through nut 7 with the keel frame 8 that plays pressuring action; Said passive band steel 9 length are less than or equal to the internal diameter of said PVC plastic pipe 1, and the width between the width between two said first recesses 3 and two said second recesses 4 is identical with the width of the keel frame 8 of said pressuring action, and said standing screw is arranged in the said PVC plastic pipe 1; The vertical external part of keel frame 8 both sides of said pressuring action is fastened in said first recess 3 and second recess 4, and it is inboard that said passive band steel 9 is arranged on said PVC plastic pipe 1 other end.
For the shutoff sleeve pipe; Build when preventing concreting into and influence the hole quality in the sleeve pipe; Also comprise with galvanized sheet iron and shear the circular cover that forms; Said circular cover diameter is greater than the external diameter of said PVC plastic pipe 1, and the center of said circular cover has out two different company holes of diameter, and said circular cover passes the said hole that connects through said reinforcing bar handle 7 and is arranged between the keel frame 8 and reinforcing bar handle 7 of said fixation.
According to the job practices that above-mentioned PVC sleeve pipe is made hole to be provided,, each platform hole reserve position is located in advance at first according to the hot-water heating drawing; Before civil engineering base plate muscle was laid, opsition dependent was fixed on said PVC sleeve pipe on the bamboo splint through said self-tapping screw 6 then, because the hardness of bamboo offset plate is higher, directly be difficult to screw on self-tapping screw 6, and easy fracture of wire; So before installation, should pound out a duck eye with the place-centric of homemade special-purpose awl hole to be provided on the bamboo offset plate earlier, and then sleeve pipe is put, tighten standing screw and build gland; After treating concrete setting at last, taking out said support fixation body, is dismountable sleeve pipe toward the said PVC sleeve pipe of inboard extruding.
As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
