Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to a special water-stopping structure used for connecting a thermal insulation and sound insulation board roof with a water room.

[0002] The present invention relates to the technical field of building engineering, and in particular to a method for laying a thermal insulation and sound insulation board floor and a special water-stopping structure for a water-containing room, the method being intended to simplify the construction process and improve the construction efficiency. Background Art

[0003] The construction of composite thermal insulation and sound insulation board floor and roof engineering is a relatively new construction technology. The waterproof construction technology of the connection between the floor thermal insulation and sound insulation board of the construction project and the water room is still in the exploratory stage. The conventional construction method of the connection between the floor thermal insulation and sound insulation board of the construction project and the water room is to set a concrete step with the same width of the threshold between the water room and the floor thermal insulation and sound insulation board, and the height of the step is level with the top of the thermal insulation and sound insulation board. This method requires pouring after the floor of the water room and the floor thermal insulation board is laid, which affects the progress of the project, is labor-intensive and time-consuming, and is not conducive to the protection of the finished product.

[0004] The patent with application number CN202011042363.3 provides a precast concrete step and a construction method thereof. The precast concrete step includes a straight step block and a corner step block. The bottom surface of the step block is stepped or grooved. A U-shaped steel bar is provided at the bottom of the step block. The two ends of the U-shaped steel bar are embedded in the step block. The bent part of the U-shaped steel bar protrudes from the bottom surface of the step block. The U-shaped steel bar is used as a lifting ring when the step block is transported, and as a supporting foot when the step block is connected to the floor slab. The present invention combines the precast concrete step with grouting construction, and the bottom surface of the step block is designed to be a special stepped or grooved shape, which increases the penetration path.

[0005] However, the above patent technology still uses concrete steps to achieve waterproof treatment at the connection with the water room, which cannot fully match the construction of composite thermal insulation and sound insulation board floor and roof engineering, and cannot solve the technical problems existing in the prior art. Therefore, it is particularly important to develop a water-stop structure that can simplify the construction process, improve construction efficiency and ensure waterproof effect.
