Description

Technical Field

[0001] The utility model relates to the technical field of building construction, particularly to the technical field of adding daylighting wells to the top slab of the already constructed structure in the basement, and specifically refers to a construction structure for adding daylighting wells to the top slab of the already constructed structure in the basement. Background Art

[0002] Building construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc.

[0003] A basement is a room in a building that is below the outdoor ground level. Building a basement below the ground floor of a house can improve the efficiency of building land use. For some high-rise buildings with a large buried depth of the foundation, making full use of this depth to build a basement has excellent economic and usage effects.

[0004] However, sometimes in order to ensure the ventilation and daylighting requirements of the basement, it is necessary to add daylighting wells to the top slab of the already constructed structure in the basement. For example, as Figure 1 shown, the basement has a front cross beam 1, a rear cross beam 2, a left longitudinal beam 3, a middle longitudinal beam 4, a right longitudinal beam 5, a left top slab 6 and a right top slab 7. The front cross beam 1 and the rear cross beam 2 are both vertically arranged and both arranged along the left-right direction and spaced apart from each other front and rear. The left longitudinal beam 3, the middle longitudinal beam 4 and the right longitudinal beam 5 are all vertically arranged and all arranged along the front-rear direction and spaced apart from each other left and right. The left longitudinal beam 3 and the middle longitudinal beam 4 are both located between the front cross beam 1 and the rear cross beam 2 and are respectively connected to the front cross beam 1 and the rear cross beam 2. The right longitudinal beam 5 is located on the right side of the front cross beam 1 and the rear cross beam 2 and is respectively connected to the front cross beam 1 and the rear cross beam 2. The top surface of the rear cross beam 2 is flush with the top surface of the right longitudinal beam 5. The top surface of the left longitudinal beam 3 is flush with the top surface of the middle longitudinal beam 4 and is lower than the top surface of the rear cross beam 2 and the top surface of the right longitudinal beam 5. The left top slab 6 and the right top slab 7 are both horizontally arranged and spaced apart from each other left and right. The left top slab 6 is located between the front cross beam 1, the left longitudinal beam 3, the rear cross beam 2 and the middle longitudinal beam 4 and is respectively connected to the front cross beam 1, the left longitudinal beam 3, the rear cross beam 2 and the middle longitudinal beam 4. The right top slab 7 is located between the front cross beam 1, the middle longitudinal beam 4, the rear cross beam 2 and the right longitudinal beam 5 and is respectively connected to the front cross beam 1, the middle longitudinal beam 4, the rear cross beam 2 and the right longitudinal beam 5. Now it is necessary to set daylighting wells at the rear half part position (the intersection position of the two diagonal lines on the left) of the left top slab 6 and the rear half part position (the intersection position of the two diagonal lines on the right) of the right top slab 7.
