Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a prefabricated stairwell gap blocking device and a construction method thereof. Background Art

[0002] Prefabricated buildings are increasingly being used in modern building structures due to their advantages such as shortened construction periods and energy conservation. Prefabricated stairs are one type of prefabricated structure. Compared to cast-in-place stairs, prefabricated stairs usually have gaps between them to facilitate hoisting and construction, which affects the connection and penetration of the drip line at the bottom of the stair slab. The gaps in prefabricated staircases are sealed after construction is completed, often using a hanging formwork method. This not only increases the difficulty of construction and fails to meet the accuracy of grouting, but also affects the construction progress of the drip line at the bottom of the stair slab, the ground of the rest platform, and the staircase floor paint. The sides of the stairs have not been polished and there is a lot of garbage in the gaps, which is difficult to handle and affects the overall bonding strength. Summary of the Invention

[0003] In order to overcome the defects of the existing technology, a prefabricated stairwell gap sealing device and a construction method thereof are now provided to solve the problem that garbage easily enters the gaps of the existing prefabricated stairwells and the treatment is time-consuming and labor-intensive.

[0004] To achieve the above-mentioned purpose, a prefabricated stairwell gap sealing device is provided, comprising:

[0005] The lower end of the ascending prefabricated staircase and the upper end of the descending prefabricated staircase are installed on the supporting beam of the stairwell, and a gap is formed between the ascending prefabricated staircase, the descending prefabricated staircase, and the beam surface of the supporting beam. The gap covering panel is laid on the lower end of the ascending prefabricated staircase and the upper end of the descending prefabricated staircase to cover the gap.

[0008] Furthermore, one end of the caulking panel is detachably connected to the lower end of the ascending prefabricated staircase by bolts, and the other end of the caulking panel is detachably connected to the upper end of the descending prefabricated staircase by bolts.

[0009] Furthermore, the closing plate is arranged in a vertical direction, and the upper end of the closing plate is detachably connected to the side of the gap-covering panel through a fastener.

[0011] Furthermore, a first anti-slip pattern is formed on a side of the hanging plate facing the closing plate, and a second anti-slip pattern is formed on an outer side of the closing plate, wherein the second anti-slip pattern is engaged with the first anti-slip pattern.

[0012] Furthermore, there are two hanging plates, which are respectively arranged on opposite sides of the supporting base plate.

[0013] Furthermore, the base is provided with a threaded hole, the locking piece is formed with an external thread, the locking piece is screwed into the threaded hole, and one end of the locking piece extends into the through hole and presses against the hanging plate.

[0014] The present invention provides a construction method of a prefabricated stairwell gap sealing device, comprising the following steps:

[0015] Laying the seam-covering panels on the lower end of the ascending precast staircase and the upper end of the descending precast staircase to cover the seam openings of the seams, and covering the ends of the seams with closing panels, so that the bottom support plate is arranged below the supporting beams;

[0016] The bottom supporting plate is lifted and lowered so as to be supported on the bottom of the supporting beam.

[0017] The beneficial effects of the present invention are that the prefabricated staircase gap sealing device can effectively adjust the installation elevation of the support plate according to the size of the gap in the prefabricated staircase and the height of the prefabricated stairs. At the same time, the gap-sealing panel is fixed to the prefabricated stairs by bolts, thereby achieving convenient and accurate sealing of the gap in the prefabricated staircase.
