Description

Technical Field

[0001] This utility model relates to a temporary sealing structure for the opening of a vehicle base roof, belonging to the field of building engineering technology. Background Technology

[0002] In my country, the development of vehicle depots with overpasses is becoming increasingly common. In these overpass projects, the area beneath the overpass is primarily used for daily operations such as vehicle parking, cleaning, inspection, and maintenance, while the area above is mainly for property development functions, such as residential, commercial, and office spaces. Because the land use and development entities above and below the overpass may differ, the secondary development of the overpass generally lags behind the implementation of the underlying vehicle depot platform. Therefore, the development timeline for the overpass is highly likely to be delayed compared to the overpass development, and this delay is subject to considerable uncertainty.

[0003] Although the development of the superstructure is generally implemented in two phases, the superstructure and the area beneath it require integrated design, and both phases must independently meet architectural and fire safety design requirements. Therefore, openings such as elevator shafts, staircases, and ventilation shafts will be left on the surface of the superstructure platform for later use. If the later development is not implemented, these openings will remain exposed on the roof for a long time. Since these openings are generally located above the vehicle depot warehouses, if appropriate measures are not taken, rainwater may enter the vehicle depot warehouses through these openings during later use of the depot.

[0004] Currently, many projects use concrete structures (permanent concrete flanges + concrete slabs) for sealing. While this method effectively solves the aforementioned problems, it is relatively expensive. If the secondary development time is close to the platform implementation time, and the concrete structure needs to be demolished in a short period of time, it will result in significant waste. Furthermore, the vibration during the later chiseling process of the permanent concrete flange will have a certain impact on the cover plate structure. Utility Model Content

[0005] This utility model addresses the aforementioned shortcomings of existing technologies by proposing a temporary sealing structure for the openings of vehicle base roofs. This structure can economically, reasonably, safely, and reliably complete the temporary sealing task of the openings of vehicle base roofs, and facilitates subsequent dismantling and formal construction.

[0006] This utility model relates to a temporary sealing structure for the opening of a vehicle base roof, including a permanent concrete flange;

[0007] The concrete permanent flange has structural column inserts at several preset positions, and several structural columns are formed by pouring based on the structural column inserts;

[0008] A masonry wall is provided above the permanent concrete flange and between two adjacent structural columns. The masonry wall and the structural column are connected as one unit at the top by a ring beam.

[0009] The ring beam is equipped with embedded parts, and several steel beams are fixed on the top of the embedded parts. The roof profiled steel sheet is fixed on the steel beams; corresponding to the steel beams, compression bars and diagonal tie bars are provided.

[0010] In some specific implementation schemes, the compression bar is fixedly connected to two adjacent steel beams, and the two ends of the diagonal tie rod are fixedly connected to the two adjacent steel beams respectively.

[0011] The openings of the vehicle base are generally rectangular, and structural columns should be placed at least at the four corners of the opening. The distance between two adjacent structural columns on the same side of the permanent concrete flange should not be greater than 3 meters. If the distance between two adjacent corners of the permanent concrete flange is greater than 3 meters, additional structural columns should be added.

[0012] Compared with the prior art, the present invention has the following technical effects:

[0013] 1) A reinforced concrete and masonry wall is installed around the opening. This meets the need for water blocking at the opening and facilitates later demolition while minimizing the overall construction cost. The added masonry wall and ring beam structure reduce the height of the reinforced concrete wall, so that the height of the reinforced concrete wall remains the height of the permanent wall, avoiding the need to remove excess wall and avoiding the adverse effects of vibration on the cover plate structure during the removal process.

[0014] 2) The structural columns ensure a reliable connection between the masonry structure and the permanent concrete flange;

[0015] 3) A lightweight steel structure consisting of steel beams and profiled steel roofing sheets is used, and temporary sealing plates replace concrete floor slabs, which significantly reduces the roof load and cost, and facilitates later demolition and formal construction.

[0016] 4) Ensure the safety of the temporary sealing cover plate of the lightweight steel structure under its own weight, wind load and snow load by using compression bars and diagonal tie rods. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, this embodiment includes a permanent concrete flange 100.

[0025] The permanent concrete flange 100 has structural column reinforcing bars 201 at several preset positions, and several structural columns 200 are formed by pouring based on the structural column reinforcing bars 201. Preferably, taking a cover opening with an outer diameter of 9m × width of 6m as an example (the same below), three structural columns are set on each side in the width direction, two of which are set at the corner of the cover opening, and the third structural column is set between the two structural columns on the same side, and the three structural columns are arranged at equal intervals.

[0026] A masonry wall 300 is provided above the permanent concrete flange and between two adjacent structural columns. The masonry wall 300 and the structural column 200 are connected at the top by a ring beam 400, the width of which is the same as the thickness of the masonry wall. Preferably, the height of the masonry wall plus the permanent concrete flange is designed to be 2m, wherein the height of the permanent concrete flange is not less than 0.5m.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the ring beam 400 has embedded parts 500, and several steel beams 600 are fixed to the top of the embedded parts 500. Roof profiled steel sheets 900 are fixed on the steel beams. Preferably, six T-shaped steel embedded parts are set on each side of the opening width direction. Each steel embedded part is constructed by welding a top steel plate and several J-shaped steel feet to the bottom. The J-shaped steel feet are cast into the ring beam, with the top steel plate protruding. Steel beams are welded onto two pairs of embedded parts in the width direction. The steel beams are arranged along the length of the opening, thus six steel beams are arranged. As the main load-bearing components of the roof, the height of the steel beams is designed to be 1 / 25 to 1 / 30 of the span, and the spacing is no more than 1.5 meters.

[0028] Preferably, corresponding to the steel beam 600, a pressure bar 700 and a tie bar 800 are also provided; the pressure bar is fixedly connected to two adjacent steel beams with a spacing of no more than 3 meters, and the two ends of the tie bar are fixedly connected to two adjacent steel beams respectively.

[0029] The following steps are used to construct the aforementioned temporary sealing structure:

[0030] S1, pour concrete around the opening of the upper platform according to the permanent flange height to obtain a permanent concrete flange; before pouring, reserve structural column reinforcement bars at the preset position;

[0031] S2. After the concrete strength reaches the design requirements, masonry walls are built on the permanent concrete flange along the height direction, and structural columns are poured.

[0032] S3, construct a ring beam with steel reinforcement at the top of the structural column and masonry wall and set embedded parts, pour concrete to obtain the ring beam, so that the ring beam is connected to the structural column as one piece;

[0033] S4 connects the embedded parts to the steel beam, and reinforces the steel beam with compression bars and diagonal bracing; then fix the roof profiled steel sheet on the steel beam as a temporary steel roof.

[0034] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
