Problems solved by technology

[0002] At this stage, there are many reserved casings for engineering shear walls, and most of them use PVC casings and casings processed with thin-walled iron pipes to reserve holes. This traditional method is not fixed enough, which may easily cause the reserved holes to shift. , PVC pipes are brittle and are easily damaged during the removal of the casing, resulting in a deviation in the size of the hole, which will increase the work of chiseling and repairing later, which will have a certain impact on the main structure and later waterproof construction; in addition, the PVC pipe is a waste of material as a reserved hole casing At the same time, because the PVC pipe wall is smooth, the hole wall is smooth after the hole is formed, which is not conducive to the later hanging hole, and it is easy to leak after the hole is sealed; while the thin-walled iron pipe reserved hole casing is not easy to grasp the removal time, and it needs to be removed from the top plate when it is reused. Take off the brush oil, increase the workload

Embodiment 1

[0036] see Figure 1-5 , a reusable reserved hole reservation device, which includes an inner casing 4, one end of the top of the inner casing 4 is fixedly installed with a top cover plate 3 for sealing the top, the inner A rubber tube 5 is set on the outside of the casing 4, and a long screw 7 is mounted on the middle part of the top cover plate 3 through thread fit. The top of the long screw 7 is provided with a top hexagonal head 2, and Set has 8 nuts. The above-mentioned reserved hole reservation device can be used in the construction process of the reserved hole in the shear wall, and the construction of the reserved hole can ensure the dimensional accuracy of the reserved hole and effectively avoid the influence of concrete vibration. Flexible processing and molding, saving labor processing costs.

[0037] Further, the top cover plate 3 is fixed on the top of the inner casing 4 by means of welding or screw connection. The above-mentioned top cover plate 3 can effectiv...

Embodiment 2

[0045] A method for constructing a reserved hole with a reusable reserved hole reservation device includes the following steps:

[0046] Step 1: Cut the rubber tube 5 of the corresponding height according to the thickness of the shear wall 11 to be poured, and select the inner casing 4 of the corresponding height;

[0047] Step 2: Position the inner sleeve 4 at the position where the hole needs to be reserved, and pass the long screw 7 through the threaded hole 10 of the top cover plate 3, and make the bottom end pass through the through hole 12 of the template 9, and then use The nut 8 locks the long screw rod 7, and then fixes the entire inner casing 4 on the template;

[0048] Step 3: Set the rubber tube 5 on the outside of the inner casing 4;

[0049] Step 4: After all the pre-embedded casings are fixed, the pouring operation is carried out, and the vibrating rod is used to vibrate, and then the concrete is vibrated;

[0050] Step 5: After the concrete reaches the initia...

Abstract

The invention provides a reusable reserved hole reserving device and a construction method. The device comprises an inner sleeve; a top sealing cover plate used for sealing the top of the inner sleeveis fixedly installed at one end of the top of the inner sleeve; the exterior of inner sleeve is sleeved with a rubber pipe; a long screw rod is installed in the middle of the top sealing cover platein a threaded fit mode; a top hexagonal head is arranged at the top of the long screw rod; and the long screw rod is sleeved with a nut. By the adoption of a steel sleeve reserving device, after concrete pouring is completed, a steel sleeve can be smoothly pulled out from an upper portion and repeatedly used, and the steel sleeve can be used as a pipeline wall bushing after a top cover and a handle are detached in the later period, so that the positive boosting effect is achieved on on-site environmental protection and civilized construction.

Description

technical field [0001] The invention belongs to the field of building material cutting devices, in particular to a reusable hole reservation device and a construction method. Background technique [0002] At this stage, there are many reserved casings for engineering shear walls, and most of them use PVC casings and casings processed with thin-walled iron pipes to reserve holes. This traditional method is not fixed enough, which may easily cause the reserved holes to shift. , PVC pipes are brittle and are easily damaged during the removal of the casing, resulting in a deviation in the size of the hole, which will increase the work of chiseling and repairing later, which will have a certain impact on the main structure and later waterproof construction; in addition, the PVC pipe is a waste of material as a reserved hole casing At the same time, because the PVC pipe wall is smooth, the hole wall is smooth after the hole is formed, which is not conducive to the later hanging ho...
