Description

Height-adjustable concrete reserved hole gap plugging device

Technical Field

The utility model relates to a construction technical field, in particular to entrance to a cave gap plugging device is reserved to concrete with adjustable height.

Background

At present, when a building concrete floor slab is poured, holes need to be reserved for subsequent construction convenience, so that the trouble of punching during subsequent construction and irregular damage to a wall body or the concrete floor slab are avoided. Need carry out the shutoff to reserving the hole after the construction is accomplished, to the shutoff of reserving the entrance to a cave, traditional way has two kinds: firstly, use the plank sheathing, dig out the round hole that is close with drainage tubular product diameter with the plank sheathing and cut it into two halves to with two halves plank sheathing amalgamation in the drainage tubular product outside, later through the flitch strip with plank sheathing bottom support, the top is in the floor downside, then pour into the concrete on the floor can. Secondly, a plywood or rubber-plastic heat-insulation board is used for self-making a template on site, the template is cut into various small square plates which are larger than the opening of the hole, then round holes with the diameter similar to that of the pipeline are dug out and cut into two halves, two small holes are knocked in each half, iron wires penetrate through the two small holes and support reinforcing steel bars or bamboo sheets on the bottom surface of the template, one person supports the template and the reinforcing steel bars on the floor surface when the template is used, the other person lifts the iron wires from the reserved hole to the upper surface of the floor, the reinforcing steel bars are transversely placed on the floor surface to screw the iron wires tightly, and then concrete is poured on the floor surface. Above-mentioned two kinds of tradition way need two constructors to mutually support, not only the construction is troublesome, waste time and energy, and the construction face convex-concave is uneven moreover, and concrete protrusion floor plane pollutes the pipeline wall, needs artifical later stage clearance chisel to grind, injures the pipeline slightly carelessly, and the probability that leads to the seepage is great, increases time cost and cost of labor, and the construction equipment subassembly all is fixed mode moreover, can't adjust, and the limitation is great in the use, and practical function is not good.

Patent CN 208734087U discloses a plugging support plate for a reserved hole of a pipeline, which comprises a first plugging plate and a second plugging plate which are closed to form a circular through hole matched with the pipeline; the lower end faces of the first plugging plate and the second plugging plate are respectively connected with a first semicircular ring and a second semicircular ring, and the first semicircular ring and the second semicircular ring are closed to form a circular through hole matched with the pipeline; the upper end surfaces of the first blocking plate and the second blocking plate are respectively connected with self-adhesive sponges, and the inner side surfaces of the first semicircular ring and the second semicircular ring are respectively connected with self-adhesive sponges; during the use, first shutoff board and second shutoff board dock in the pipeline outside, and the up end of first shutoff board and second shutoff board is connected with the roof face through self-adhesion sponge respectively, and the medial surface of first semicircle ring and second semicircle ring is connected with the pipeline outside through self-adhesion sponge respectively.

Although the aforesaid patent can realize quick installation, high durability and convenient use, it adopts the self-adhesion sponge to be connected first shutoff board and second shutoff board and roof face, the self-adhesion sponge soaks in the concrete for a long time, viscidity reduces, in addition the gravity of concrete, can lead to the pine of shutoff board caving, thereby lead to the construction surface convex-concave uneven, can the concrete directly drop when serious, waste time and energy, seriously influence construction quality, it is also exactly that the medial surface of first semicircle ring and the second semicircle ring of first shutoff board and second shutoff board downside also is connected with the pipeline outside through the self-adhesion sponge, because the cohesive force of self-adhesion sponge is limited, can not guarantee that the pipeline does not take place the skew, lead to pouring the pipeline slope behind the gap, thereby influence subsequent construction quality.
