Description

Technical Field

[0001] The utility model relates to a basement exterior wall waterproof structure, in particular to a basement exterior wall waterproof structure which is easy to construct. Background Art

[0002] The basement is located at the bottom of civil buildings, and exists in underground garages, underground civil air defense, and storage rooms. The construction area is large, the construction workload is large, and the construction of underground projects is relatively difficult. When the basement waterproofing layer is completed and the earth is backfilled, the basement will be buried underground for a long time, and later maintenance will be very difficult. The essence of the basement waterproofing project is to use rigid waterproofing (self-waterproofing) as the basis, plus a composite waterproofing layer such as roll waterproofing, film waterproofing, or a rigid and flexible waterproofing form formed by the superposition of these, to form a closed waterproofing system at the basement exterior wall and raft slab. After the exterior wall waterproofing construction is completed, the foundation pit fertilizer trough will be backfilled, and the earth backfilling process will often cause damage to the exterior wall waterproofing layer. In order to reduce the damage to the exterior wall waterproofing layer, a protective layer is usually added to the outside of the waterproofing layer, and extruded board is the most widely used protection method. However, at this stage, the construction of exterior wall extruded board usually uses double-sided tape to fix it on the roll material. This fixing method has the following three shortcomings:

[0003] 1. The adhesion of the extruded board is insufficient, and it is difficult to prevent the extruded board from falling off during the backfilling process of the foundation pit fertilizer trough, resulting in poor waterproof protection of the exterior wall.

[0004] 2. On-site construction is inconvenient. The construction space at the bottom of the basement exterior wall is usually limited, and there are problems with the transportation and stacking of extruded board materials. The construction is time-consuming and labor-intensive.

[0005] Therefore, the existing technology has the problems that the extruded board is easy to fall off and the construction is inconvenient. Utility Model Content

[0006] The purpose of the utility model is to provide a waterproof structure for the exterior wall of a basement that is easy to construct. The utility model has the characteristics of being easy to construct and the extruded board not being easy to fall off.

[0007] The technical solution of the utility model is: an easy-to-construct basement exterior wall waterproof structure, including an exterior wall waterproof layer located outside the basement exterior wall, and a waterproof protective layer is provided outside the exterior wall waterproof layer; the waterproof protective layer includes a plurality of columns of extruded board groups arranged in sequence, and both ends of the top of each column of extruded board groups are connected to steel pipe fixing points located at the top of the basement exterior wall through steel rings.

[0008] In the aforementioned easy-to-construct basement exterior wall waterproof structure, each row of extruded board groups includes multiple extruded boards distributed up and down, with hollow steel pipes embedded at both ends of the extruded boards. U-shaped iron rings are provided at the upper and lower ends of the hollow steel pipes, and the U-shaped iron rings are connected with connectors; the upper and lower adjacent extruded boards are connected to the U-shaped iron rings at the corresponding positions via connectors.

[0009] In the aforementioned easy-to-construct basement exterior wall waterproof structure, backfill soil is provided on the outside of the waterproof protective layer.

[0010] In the aforementioned easy-to-construct basement exterior wall waterproof structure, the two ends of the steel sleeve are respectively connected to the steel pipe fixing point and the connecting piece on the U-shaped iron ring on the upper end of the top extruded plate.

[0011] Compared with the prior art, the present invention achieves mutual connection between upper and lower adjacent extruded boards by embedding hollow steel pipes with U-shaped iron rings at both ends in the two ends of the extruded boards, and connecting the adjacent extruded boards via connectors; and achieves connection between the left and right adjacent extruded board groups by setting steel pipe fixing points on the top of the basement outer wall and connecting the extruded boards to the steel pipe fixing points using steel sleeves. Compared with the traditional extruded board construction method, the present invention has the following advantages: 1. More convenient construction, using steel sleeves and connectors to achieve the laying of a whole row of extruded boards, saving construction time; 2. Improved protection effect, the connection result of the present application has a better fixing effect than double-sided tape, can effectively prevent the extruded boards from falling off, and can effectively improve the protection effect. In summary, the present invention has the characteristics of convenient construction and the extruded boards are not easy to fall off. BRIEF DESCRIPTION OF THE DRAWINGS
