Description

Technical Field

[0001] This utility model belongs to the field of building underground waterproofing engineering technology, and in particular relates to a waterproof structure for a replacement support plate strip for the exterior wall of a multi-story basement structure. Background Technology

[0002] In basement construction, especially when using an internal support system for earthwork excavation and basement structural construction, the original internal support structure needs to be removed as the basement structure is gradually constructed upwards. Replacement support strips are concrete slab strip structures installed between the basement structure's exterior walls and surrounding retaining structures (such as diaphragm walls and piles) before the removal of the internal supports. These strips can transfer horizontal forces and replace the internal supports, providing lateral support to the retaining structure, ensuring the stability of the retaining structure during subsequent construction phases and the safety of the basement structural construction.

[0003] With the increasing number of multi-story basement structures in construction engineering designs in recent years, the replacement support strip, as an important component of the foundation pit support system during the structural construction phase, is often subject to the constraints of the foundation pit and trench construction conditions when it is removed. Furthermore, the unremoved replacement support strip will affect the continuous construction of the exterior wall waterproofing, making the junction between the basement exterior wall and the replacement support strip a node with a significant risk of leakage in the underground waterproofing project. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof structure for the replacement support strip of the exterior wall of a multi-story basement structure. It features multiple waterproofing measures at the replacement support strip location, utilizing the self-waterproofing of the concrete structure combined with waterproof membranes and waterproof coatings. This provides layer-by-layer protection at areas prone to leakage, reducing the scope of waterproofing termination. It solves the problem of waterproofing termination at the junction of the exterior wall structure and the replacement support strip, effectively reducing the risk of leakage.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A waterproof structure for a replacement support strip for the exterior wall of a multi-story basement structure, comprising plastic corner protectors installed at two internal corners between the replacement support strip and the basement exterior wall, a basement floor slab integrally formed with the replacement support strip at the end of the replacement support strip, a pit retaining structure at the end of the replacement support strip away from the basement floor slab, a waterproof coating applied between the arc-shaped surface of the plastic corner protectors and the basement exterior wall and the replacement support strip, a waterproof additional layer provided on the waterproof coating, a waterproof membrane covering the waterproof additional layer and the waterproof coating provided on the waterproof additional layer, an aluminum alloy pressure strip placed above the upper end of the waterproof membrane at the top of the replacement support strip, a plurality of waterproof nails penetrating through the top of the aluminum alloy pressure strip, the ends of the waterproof nails penetrating through the waterproof membrane and the waterproof coating and embedded in the interior of the replacement support strip.

[0006] The present invention provides a waterproof structure for the replacement support strip of the exterior wall of a multi-story basement structure as described above. Further, a sealant is provided on the surface of the waterproof membrane near the end of the replacement support strip. The sealant covers the end of the waterproof membrane and the surface of the aluminum alloy strip and the waterproof nail and is bonded to the replacement support strip.

[0007] The waterproof structure of the replacement support strip for the exterior wall of a multi-story basement structure described above is further characterized by: an L-shaped cavity being formed on the right-angled surface of the plastic corner protector; the inner cavity of the L-shaped cavity being filled with waterproof adhesive; and the L-shaped cavity being bonded to the inside corner of the replacement support strip and the exterior wall of the basement by the waterproof adhesive.

[0011] The present invention provides a waterproof structure for the replacement support strip of the exterior wall of a multi-story basement structure as described above, further comprising: the end of the waterproof membrane near the replacement support strip is bonded to the replacement support strip.

[0012] The beneficial effects of this utility model are: 1. This utility model fixes plastic corner protectors to the inside corners of the support strip and the basement exterior wall using waterproof adhesive and waterproof nails. Then, waterproof coating, additional waterproof layer, and waterproof membrane are applied sequentially. An aluminum alloy strip is placed above the end of the waterproof membrane. Next, waterproof nails are installed to seal the joint. Finally, the entire joint is sealed with sealant. This multi-layered waterproofing reduces the risk of leakage and fully utilizes the self-waterproofing properties of the concrete structure of the support strip, thus achieving a good waterproofing effect. This method achieves the goal of setting up multiple waterproofing layers at the support strip location, combining the self-waterproofing properties of the concrete structure with waterproof membrane and waterproof coating, and providing layered protection at easily leaking areas, thereby reducing the scope of the waterproof joint.

Multiple countersunk holes 13 are formed on the arc-shaped surface of the plastic corner protectors 5. Waterproof nails 14 penetrate the internal cavities of the countersunk holes 13. The waterproof nails 14 pass through the plastic corner protectors 5 and are embedded in the interior of the support strip 2 and the foundation pit retaining structure 3, respectively. In conjunction with the use of 2.14, waterproof adhesive is used at L-shaped cavity 12 to pre-fix the plastic corner protector 5. Then, waterproof nails 2.14 are driven through countersunk holes 13 and inserted into the interior of the replacement support strip 2 and the basement exterior wall 4 for reinforced fixing, effectively preventing displacement of the plastic corner protector 5 during the laying of the roll material. The end of the replacement support strip 2 is provided with a basement floor slab 1 integrally formed with the replacement support strip 2. The end of the replacement support strip 2 away from the basement floor slab 1 is provided with a foundation pit retaining structure 3.
