Description

A waterproof sealing device for reserved openings of pressure pools

technical field

The utility model relates to a waterproof sealing device, in particular to a waterproof sealing device used for a reserved opening of a pressure pool.

Background technique

Generally, the building pressure pool is located between the structural floors. The pool needs to store water for a long time, so the waterproofing of the pool body is particularly important. The waterproof effect after the reserved opening of the pool is blocked is especially important, otherwise it will affect the normal use of adjacent buildings.

The traditional method of closing the opening of the pool: use reinforcement around the opening, chiseling the opening, and after the formwork is set up, use a higher-grade micro-expansion waterproof concrete to pour it densely, and strengthen the surrounding area of the opening during waterproofing construction. With the traditional pool sealing method, the junction of new and old concrete cannot be connected tightly. After a period of time, shrinkage cracks will appear at the junction of new and old concrete, which will damage the waterproof layer. The waterproof effect is not good, and frequent maintenance is required, which affects the use of the pool.

Utility model content

The purpose of the utility model: to provide a device capable of effectively waterproofing the reserved hole of the pressure pool to ensure the normal use of the pressure pool.

Technical solution: The waterproof sealing device for the reserved opening of the pressure pool described in the utility model includes a sealing steel plate, expansion bolts and two annular rubber pads; a ring of sealing steel strips is arranged on the side of the sealing steel plate; There are bolt holes on the top and along the inner and outer sides of the sealing steel bar at intervals; two annular rubber pads are respectively laid along the inner and outer sides of the sealing steel bar, and the height of the sealing steel bar is greater than the thickness of the ring rubber pad; expansion bolts are used to wear After passing through the bolt hole and the annular rubber pad, the sealing steel plate is installed on the reserved hole, and the sealing steel strip is embedded in the annular groove preset at the edge of the reserved hole.

The use of sealing steel strips can not only ensure the positioning effect of the sealing steel plate, but also play a certain role in waterproofing; two ring-shaped rubber pads are respectively located on the inner and outer sides of the sealing steel strips, which have a high waterproof effect and ensure that there will be no water leakage ; There will be no problem of shrinkage cracks at the interface between new and old concrete when the sealing plate is used for sealing, ensuring the long-term stable use of the pressure pool.

As a further limiting solution of the present invention, the sealing steel strip is located in the middle between the edge of the sealing steel plate and the edge of the reserved opening. The use of sealing steel bars in the middle can have a better symmetrical compression effect after the expansion bolts are tightened, ensuring waterproof and compact.

As a further limiting solution of the present invention, the distance between the edge of the sealing steel plate and the edge of the reserved hole is greater than 200mm. Adopting a spacing greater than 200mm can facilitate the setting of the sealing steel strip and the annular rubber pad, ensuring stability and sealing after installation.

As a further limiting solution of the present invention, the height of the sealing steel strip is 10mm. The height of 10mm can not only be embedded in the annular groove at the edge of the reserved opening, but will not damage the strength of the concrete structure of the reserved opening.

As a further limiting solution of the present invention, the thickness of the annular rubber pad is 5 mm. The use of a 5mm thick ring-shaped rubber pad can ensure a tight waterproof effect without making the sealing steel plate protrude too high.

Compared with the prior art, the utility model has the beneficial effects as follows: (1) adopting the sealing steel bar can not only ensure the positioning effect of the sealing steel plate, but also play a certain waterproof effect; (2) adopt two ring-shaped rubber pads They are respectively located on the inside and outside of the sealing steel bars, which have a high waterproof effect and ensure that there will be no water leakage; (3) The use of sealing steel plates for sealing will not cause shrinkage cracks at the interface between new and old concrete, ensuring that the pressure pool will last for a long time stable use.

detailed description

The technical solution of the utility model will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

Example 1:

As shown in Figures 1 and 2, the waterproof sealing device for the reserved opening of the pressure pool of the present invention includes: a sealing steel plate 2, an expansion bolt 4 and two annular rubber pads 5.

Among them, a ring of sealing steel strip 3 is arranged on the side of the sealing steel plate 2; bolt holes are arranged on the sealing steel plate 2 and along the inner and outer sides of the sealing steel strip 3 at intervals; 3, and the height of the sealing steel strip 3 is greater than the thickness of the annular rubber pad 5; the expansion bolt 4 is used to pass through the bolt hole and the annular rubber pad 5 to install the plugging steel plate 2 on the reserved hole 1, And the sealing steel bar 3 is embedded in the annular groove preset at the edge of the reserved hole 1; the sealing steel bar 3 is located in the middle between the edge of the sealing steel plate 2 and the edge of the reserved hole 1; The edge distance of the hole 1 is greater than 200mm; the height of the sealing steel strip 3 is 10mm; the thickness of the annular rubber pad 5 is 5mm.

When the waterproof sealing device for the reserved opening of the pressure pool of the utility model is manufactured, the thickness of the sealing steel plate 2 is 16~20mm, wherein, when the opening is ≤400mm, the thickness of 16mm is used; when 400mm<the opening ≤600mm, the thickness of 18mm Thick ones; when 600mm<hole ≤ 800mm, use 20mm thick ones, and each side of the plugging steel plate 2 is 200mm larger than the hole.
