Technical field
[0001] The utility model relates to a sealing device for double T-plate gaps in the field of construction, and is particularly suitable for treating various gaps in double T-plates. It mainly solves the problems of double T-plate gaps being difficult to seal due to operating space and failing to meet aesthetic requirements, thereby effectively improving construction efficiency, reducing costs, and improving economic benefits. Background Art
[0002] With the rapid development of urban economies and urban construction, prefabricated concrete components are finding widespread application and development potential due to their low cost, good integrity, convenient construction, and aesthetically pleasing appearance. Double-T slabs, in particular, are widely used in public buildings such as parking lots, industrial plants, and commercial centers due to their light weight, large span, aesthetic appearance, and formwork-free design. Utility Model Content
[0003] In order to achieve the goals of sealing the gaps of double T-plates to achieve aesthetics and convenient construction and to improve the construction level, the utility model discloses a sealing device for the gaps of double T-plates.

The utility model is characterized in that after the double T-plates are hoisted, 1mm galvanized iron sheets are used to seal the gaps between the double T-plates; wire mesh + mortar is used to seal the gaps between the double T-plates and structural beams; waterproof membrane is used to seal the gaps between the double T-plates and cast-in-situ columns; after the various gaps are sealed, overlapping layer concrete is poured; because the various gaps in the double T-plates are all between 20 and 30 mm, gypsum mortar can be directly used to fill and seal them in the subsequent decoration stage to ensure aesthetics.
[0005] The gaps between the double T plates are sealed with 1mm galvanized iron sheets with a specification of 1mm and a width equal to the gap width + 100mm. The lower part of the iron sheets is filled and sealed with gypsum mortar.
[0006] The gap between the double T plate and the cast-in-place beam is sealed with wire mesh and mortar. The wire mesh specification is the gap width + 100mm, and the lower part of the wire mesh is filled and sealed with gypsum mortar.
[0007] The gap between the double T plate and the cast-in-place column is sealed by using a waterproof membrane, a 3.0mm SBS modified asphalt waterproof membrane, and the lower part of the waterproof membrane is filled and sealed with gypsum mortar.
[0008] The beneficial effects of the utility model are that the construction is convenient, beautiful and low in cost, which greatly improves the construction efficiency, reduces the cost and improves the economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] A device for sealing gaps in double T-plates in the field of construction, including gap sealing between double T-plates, gap sealing between double T-plates and cast-in-situ beams, and gap sealing between double T-plates and cast-in-situ columns, is characterized in that: after the double T-plates 1 are hoisted, the gaps between the double T-plates 1 are sealed with 1mm galvanized iron sheets 8; the gaps between the double T-plates 1 and the structural beams 3 are sealed with wire mesh 5+mortar 6; the gaps between the double T-plates 1 and the cast-in-situ columns 3 are sealed with waterproof membrane 9; after the various gaps are sealed, the overlapping layer 2 is poured with concrete; because the various gaps in the double T-plates are all 20-30mm, gypsum mortar 4 can be directly used for filling and sealing in the subsequent decoration stage to ensure aesthetics.
[0016] The gaps between the double T plates are sealed with 1mm galvanized iron sheets with a specification of 1mm and a width equal to the gap width + 100mm. The lower part of the iron sheets is filled and sealed with gypsum mortar.
[0017] The gap between the double T plate and the cast-in-place beam is sealed with wire mesh and mortar. The wire mesh specification is the gap width + 100mm, and the lower part of the wire mesh is filled and sealed with gypsum mortar.
[0018] The gap between the double T plate and the cast-in-place column is sealed by using a waterproof membrane, a 3.0mm SBS modified asphalt waterproof membrane, and the lower part of the waterproof membrane is filled and sealed with gypsum mortar.
[0019] The utility model is further introduced below with reference to the accompanying drawings and construction procedures:
[0020] 1. After the double T-plate is hoisted;
[0021] 2. According to the on-site seam width, the iron sheet, coil and wire mesh shall be inspected on-site;
[0022] 3. Since the double T-plates are at the same height on both sides, steel nails can be used to fix the iron sheets on both sides of the double T-plates;
[0023] 4. Due to the construction differences between the double T-plate and the cast-in-place beam, the gaps are uneven, so mortar and wire mesh are used to fill them.
[0024] 5. There are construction differences between the double T-plate and the cast-in-place column, and the height and width cannot be unified, so steel nails are used to fix the waterproof membrane;
[0025] 6. After the gaps around the double T-plate are filled, the reinforcement of the laminated layer is tied and concrete is poured;
[0026] 7. In the later stage of decoration, use gypsum mortar to fill and seal the upper gaps from the bottom.
[0027] The embodiments of the present invention are used to illustrate the present invention by way of example only and not by way of limitation.
