[0006] Furthermore, the concrete layer is flush with the top surface of the receiving tank.

[0007] Furthermore, the U-shaped concrete precast blocks are processed using on-site concrete surplus materials and cast with fine stone concrete of no less than C25.

[0008] Furthermore, the prefabricated block (10) has a length of 300 mm to 400 mm, a width of 200 mm to 250 mm, and a height of 100 mm to 150 mm.

The prefabricated block comprises a plurality of blocks, and the plurality of prefabricated blocks are linearly and closely laid along the top surface of the lower masonry; the steel mesh is laid in the prefabricated block; and the concrete layer is poured on the steel mesh, thereby solving the problem in the prior art that the traditional formwork supporting the window capping is very likely to cause quality defects such as mold expansion and slurry leakage in the cast-in-place forming.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] According to a window sill capping structure and a window sill wall according to an embodiment of the utility model, Figure 1 to Figure 2As shown, it includes: a prefabricated block 10, a steel mesh 30, and a concrete layer 40. The prefabricated block 10 is a plurality of blocks, and the plurality of prefabricated blocks 10 are linearly and closely laid along the top surface of the lower masonry 20; the steel mesh 30 is laid in the prefabricated block 10; the concrete layer 40 is cast on the steel mesh 30. The combination of the steel mesh 30 and the concrete layer 40 enhances the overall strength of the window sill top structure and improves the compression and tension resistance. Through the cooperation of the prefabricated block 10 and the steel mesh 30, the seismic performance of the structure is improved, and the impact of vibration on the structure is reduced. The use of the prefabricated block 10 simplifies the construction process, reduces the complexity of on-site casting, and improves the construction efficiency. The linear and closely laid method of the prefabricated block 10 is convenient for construction personnel to quickly install and ensure the consistency of construction quality.

[0020] Furthermore, if Figure 2 As shown, the precast block 10 is a U-shaped concrete precast block with a receiving groove formed on its upper surface. The steel mesh 30 is arranged in the receiving groove formed by multiple precast blocks 10, and the concrete layer 40 is poured in the receiving groove. The receiving groove design ensures that the steel mesh 30 and the concrete layer 40 are firmly positioned in the precast block 10, prevents sliding and displacement of the material, and further improves the stability of the structure.

[0021] Furthermore, if Figure 1 As shown, the concrete layer 40 is at the same horizontal position as the top surface of the receiving groove, and the concrete layer 40 is flush with the top surface of the receiving groove, ensuring that the window sill surface is smooth and beautiful.

[0022] Furthermore, if Figure 2 As shown, the U-shaped concrete prefabricated block is processed with on-site concrete surplus and is cast with no less than C25 fine stone concrete. The concrete surplus in the on-site construction process is used to save materials and reduce costs. C25 fine stone concrete can reduce the impact of workers on vibration and noise during the construction process, and avoid diseases such as hand-arm vibration syndrome caused by workers holding vibrators for a long time. It can well improve the working atmosphere and greatly improve safety. C25 fine stone concrete has high durability and anti-aging properties, which extends its service life. The concrete surplus in the on-site construction is used to save materials and reduce costs.

[0023] Furthermore, if Figure 2 As shown, the prefabricated block 10 has a length of 300mm to 400mm, a width of 200mm to 250mm, and a height of 100mm to 150mm. The sizes of multiple prefabricated blocks 10 are unified, which ensures the overall consistency and aesthetics of the window sill top structure. The prefabricated block 10 has a flexible size range (length of 300mm to 400mm, width of 200mm to 250mm, and height of 100mm to 150mm), which can adapt to the design requirements of window sills of different specifications.

[0024] Furthermore, if Figure 1 As shown, a window sill wall comprises: a lower masonry 20, a window sill top structure, and two sections of upper masonry 50; the window sill top structure is the window sill top structure mentioned above, and the window sill top structure is laid on the upper surface of the lower masonry 20; the two sections of upper masonry 50 are laid on both sides of the top of the window sill top structure respectively, and the side walls of the two sections of upper masonry 50 and the top surface of the window sill top structure form a window 60, which not only excels in structural strength, construction convenience, durability, etc., but also has good aesthetics and adaptability, meeting the multiple requirements of modern buildings for window sill structures.

[0025] The window sill capping structure and window sill wall adopt prefabricated U-shaped concrete blocks, which completely replace the traditional window sill capping formwork construction. The prefabricated U-shaped window sill capping concrete blocks make the construction simple, improve the quality and efficiency, and reduce the risk of wall openings and leakage.
