Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically a reinforcement structure for existing basement roof slabs. Background Technology

[0002] Under normal circumstances, existing basement roof slabs do not bear concentrated loads to avoid shear failure that could cause cracking and water seepage. However, due to changes in the above-ground buildings and functional improvements, such as adding parking sheds or auxiliary rooms to the existing basement roof slab, or increasing landscape loads or modifying road loads, it is necessary to reinforce the existing basement roof slab. However, since the basement roof slab has already been constructed and the waterproofing and backfilling have been completed, the reinforcement work is quite complicated. At present, the reinforcement of existing basement roof slabs usually adopts the method of bonding steel or carbon fiber, but this method requires the removal of the original structural waterproofing and the excavation of backfill soil, which is costly. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a basement roof reinforcement structure, comprising a basement structural beam and a concrete roof slab mounted on the basement structural beam. At the junction of the basement structural beam and the concrete roof slab, the two ends of a reinforcing bar are respectively embedded into the basement structural beam and the concrete roof slab using a rebar anchoring method. Distributed reinforcing bars are evenly tied to the reinforcing bars. Formwork is erected at the positions of the reinforcing bars and distributed reinforcing bars, and concrete is poured to fix them, forming a floor slab haunch. A concrete reinforcement column is constructed below the basement structural beam. A reinforcing steel plate is bonded to the lower end of the concrete roof slab using structural adhesive. An I-beam reinforcement beam is installed at the lower end of the reinforcing steel plate. The I-beam reinforcement beam is connected to the concrete reinforcement column via a reinforcing support.

[0005] Angle steel is installed at the connection position between the aforementioned floor slab haunch and the basement structural beam. The angle steel is fixedly connected to the basement structural beam and the floor slab haunch by anchor bolts.

[0006] The aforementioned reinforcing support includes a fixed seat, a diagonal brace, and a connecting seat. The fixed seat is cast and fixed on the side wall of the reinforced concrete column. An installation plate is provided on the fixed seat. The upper part of the connecting seat is welded and fixed to the lower end face of the I-beam reinforcing beam. A connecting plate is provided at the lower end of the connecting seat. The two ends of the diagonal brace are respectively assembled and fixed to the installation plate and the connecting plate by bolts.

Formwork is erected at the reinforcement location and concrete is poured to fix it to form the floor slab haunch 5. The floor slab haunch 5 is arranged in a ring along the junction of the beam and slab, which has good integrity, low reinforcement cost, convenient construction, and does not damage the original waterproofing of the basement top slab structure. A concrete reinforcement column 6 is constructed under the basement structural beam 1 to enhance the vertical support of the structural beam. A reinforcing steel plate 7 is bonded to the lower end of the concrete top slab 2 with structural adhesive. An I-beam reinforcing beam 8 is installed at the lower end of the reinforcing steel plate 7. The I-beam reinforcing beam 8 and the concrete reinforcement column 6 are connected by a reinforcing support. The structure is simple, the construction is convenient, and it can further enhance the reinforcement and support of the top slab.

[0018] In the specific implementation process, as a preferred setting, an angle steel 9 is provided at the connection position between the above-mentioned floor slab haunch 5 and the basement structural beam 1.
