Description

Central detection device for waterproof sleeve between upper and lower floors

Technical Field

The utility model relates to a stagnant water sleeve pipe mounting process, concretely relates to central detection device of stagnant water sleeve pipe between upper and lower floor.

Background

During the construction of high-rise buildings, particularly in kitchen, toilet and balcony locations, it is often necessary to provide ducts. In order to prevent leakage around the pipeline, two water stop sleeves arranged oppositely need to be embedded in the upper and lower floors. When the water stop sleeve is pre-buried, the center coincidence of the water stop sleeve between the upper floor and the lower floor is required. However, since the concrete on the upper and lower floors is poured separately, the water stop sleeve is not fixed firmly enough during the pouring process, and is easily displaced after being extruded by the concrete or collided by workers. Based on this, when installing the downpipe between the water stopping sleeves, the center of the water stopping sleeve is usually required to be detected first, and if the center deviation of the water stopping sleeve between the upper and lower floors is within a reasonable range, the downpipe is installed; if the center deviation of the two water stop sleeves is large, the positions of the water stop sleeves need to be moved.

Currently, the central position of the water stop sleeve needs to be determined by a plumb bob instrument and other equipment. Firstly, the central position of a bottom plate water stop sleeve needs to be determined, then a laser beam is delivered upwards to the central position of the bottom plate water stop sleeve by a plumb bob instrument, a receiving target is placed at the position of a top plate water stop sleeve, the target center of the receiving target needs to be ensured to be coincided with the central point of the water stop sleeve, and then the size deviation of a red light spot and the target center (the central position of the water stop sleeve) is measured, namely the relative deviation of the central line positions of the top plate water stop sleeve and the bottom plate water stop sleeve.

The method for measuring the center of the water stop sleeve has the following defects: the central position of the water stop sleeve is determined by equipment except a plumb instrument; a leveling and centering plumb bob instrument needs to be erected, the operation is complex, and the efficiency is low; and a part of the water stopping sleeves are inconvenient for erecting a plumb instrument tripod.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a simple structure, convenient operation, and accurate stagnant water casing pipe center detection device between upper and lower floor of centering position.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a center detection device for a waterproof casing pipe between an upper floor and a lower floor is characterized by comprising an upper chuck, a lower chuck and a center detection line pendant; the upper chuck and the lower chuck are both horizontally arranged, the outer diameter of the upper chuck is matched with the inner diameter of the water stop sleeve to be tested, and a center indication icon is arranged at the center of the upper surface of the lower chuck; the central detection line drop is composed of a suspension line and a conical plumb bob connected to the lower end of the suspension line, the diameter of the conical plumb bob is gradually reduced from bottom to top, and the upper end of the suspension line penetrates through the center of the upper chuck and can move upwards under the action of external force. Thus, when the detection device is used for detecting whether the centers of the upper and lower water stopping sleeves are eccentric or overlapped, only the upper chuck is required to be horizontally clamped in the water stopping sleeve positioned on the upper floor, the lower chuck is horizontally clamped in the water stopping sleeve positioned on the lower floor, the conical plumb bob of the plumb bob naturally droops, and the lower end of the conical plumb bob is abutted against the upper end surface of the lower chuck, so that the judgment can be carried out by judging whether the position indicated by the top of the plumb bob is in the position of the center indication icon of the lower chuck, if the positions are overlapped, the centers of the upper and lower water stopping sleeves are positioned on the same axis, if the positions are positioned on one side of the center indication icon, the central positions of the upper and lower water stopping sleeves are deviated, and a deviation distance is. The suspension wire of the adopted wire drop is overlapped with the center of the upper chuck in the use state, and the plumb bob is in a vertical state under the action of gravity, so that the detection accuracy of the subsequent center position can be ensured. The detection device is simple in structure, few in operation steps and accurate in detection mode.

Furthermore, a positioning sleeve with the lower end fixedly connected with the lower chuck is further arranged on the lower chuck, and the upper edge of the positioning sleeve is bent outwards to form a ring plate hung on the upper edge of the water stop sleeve. Therefore, the arranged ring plate can be hung on the water stop sleeve, the lower chuck can be kept in a horizontal state after being inserted into the water stop sleeve, and the accuracy of a measuring result is further ensured.

Furthermore, a through hole is formed in the center of the upper chuck, and the suspension wire penetrates through the through hole and can move up and down and be positioned under the pulling action of external force. Therefore, after the suspension wire is pulled up and down and fixed, the length of the suspension wire can be adjusted according to the height of the floor, and the requirements on the length of the suspension wire under different working conditions are met.

Furthermore, the through hole consists of an upper clamping hole and a lower through hole, the diameter of the upper clamping hole is larger than that of the lower through hole, and a limiting step is formed at the joint position of the upper clamping hole and the lower through hole; the suspension wire is fixed on the upper chuck through a limiting clamping block which is tightly matched with the upper clamping hole. Therefore, the middle part of the suspension wire can be tightly pressed in the through hole by adopting the mode that the limiting clamping block is matched with the upper clamping hole, so that the suspension wire is fixed.

Furthermore, the limiting clamping block is columnar, and a handle is arranged at the upper end of the limiting clamping block. Like this, can insert or take out spacing fixture block fast through the handle during the operation, it is all very convenient to install and take off.

Furthermore, a flexible positioning cylinder matched with the lower through hole is sleeved in the middle of the suspension wire, and an assembling hole for penetrating the suspension wire is formed in the center of the flexible positioning cylinder. Therefore, the flexible positioning cylinder can ensure that the suspension wire is kept at the position of the central axis of the upper chuck after being pulled, so that the subsequent measurement result is accurate.

Furthermore, the upper chuck and the lower chuck are made of PVC plastics, so that the plastic manufacturing cost is low, and the plastic is easy to mold.

Furthermore, a plurality of pull rods are arranged on the upper chuck in the circumferential direction, the lower ends of the pull rods are fixedly connected with the upper chuck, and the upper ends of the pull rods are bent outwards and horizontally. Like this, go up the chuck and pass through the adjustment position that the pull rod also can be fine, ensure that it keeps horizontal loading, simultaneously, still conveniently take out last chuck from the sealing sleeve pipe through the pull rod, equally, it is also more convenient to install.
