Description

Technical Field

[0001] The utility model belongs to the field of construction engineering, and particularly relates to a structural construction that serves as both an equipment hoisting opening and a pressure relief opening for a machine room. Background Art

[0002] In large public building projects, especially in projects where large equipment rooms such as large transformer rooms and plate heat exchanger rooms are set in the basement, it is necessary to simultaneously meet the installation during the construction period and the maintenance or even replacement of equipment during the operation period. Therefore, hoisting holes that meet the dimensions for equipment entry and exit generally need to be designed. At the same time, in such projects, boiler rooms will also be set up. In order to discharge pressure and energy, a pressure relief opening with a considerable area generally needs to be set facing the external environment. For example, a pressure relief opening is set on the ground. The above-mentioned equipment hoisting holes and pressure relief openings are large in area and are located in open-air sites with greening on top. Such opening construction measures pose great potential hazards to the anti-seepage and waterproofing of the basement. At the same time, in the prior art, the pressure relief opening and the hoisting opening are generally set independently, and holes are respectively opened on the basement roof. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a structure in which the hoisting opening also serves as a pressure relief opening, which reduces the waterproof potential hazards brought by the opening on the basement roof and achieves the purpose of reducing project investment and improving the waterproof design.

[0004] The technical solution of the utility model is: a structure in which the hoisting opening also serves as a pressure relief opening. A vertical shaft is opened on the basement roof, and the vertical shaft extends upward out of the basement roof. The vertical shaft serves as both a hoisting opening and a pressure relief opening; a movable beam is arranged at the top of the vertical shaft, and both ends of the movable beam are supported on the inner frame beam of the vertical shaft. A hoisting hole cover plate is arranged on one side of the movable beam, and a pressure relief cover plate is arranged on the other side; the hoisting hole cover plate and the pressure relief cover plate jointly cover the top of the vertical shaft.

[0005] Based on the above technical features: the elevation of the pressure relief cover plate is higher than that of the hoisting hole cover plate; a concave notch is arranged on the movable beam, and the hoisting hole cover plate is supported on the concave notch and the well wall groove of the vertical shaft; a cushion beam is arranged on the movable beam, a supporting beam is arranged between the cushion beam and the well wall of the raised vertical shaft, and the pressure relief cover plate is arranged on the supporting beam.

[0006] Based on the above technical features: the hoisting hole cover plate is a self-waterproof concrete structure, and a foam sealant is vertically filled between the hoisting hole cover plate and the well wall groove, and a rubber cushion plate is arranged below.

[0007] Based on the above technical features: the pressure relief cover plate is a embossed steel plate with a thickness not greater than 5 mm. It bends downward along one side of the pressure relief opening and extends to cover outside the cushion beam, and bends downward along the other side and extends to cover outside the well wall of the vertical shaft; the embossed steel plate and the cushion beam and the well wall are filled and solidified with a waterproof sealant.

[0008] In the present utility model, the equipment hoisting holes and pressure relief openings are centrally arranged during the building design, and then the two are combined into one. To facilitate the activation or blasting of the pressure relief cover plate during pressure relief and release pressure to the external environment, the top of the pressure relief opening must be covered with lightweight materials, and embossed steel plates are preferably used. Considering that the hoisting opening needs to provide the largest possible opening size during the transportation and installation of equipment, movable beams are adopted, with both ends resting on the vertical shafts. When transporting and installing equipment, the movable beams, hoisting hole covers, and pressure relief covers can be removed to fully utilize the maximum space of the vertical shafts, facilitating the removal of the movable beams when ensuring the hoisting of equipment.

[0009] The beneficial effects of the present utility model are as follows: Through optimized design, the equipment hoisting holes and pressure relief openings are centrally arranged, reducing the area of openings in the basement roof, reducing the potential for basement leakage, and taking into account the outdoor landscape and decorative effects; at the same time, due to the use of conventional waterproof measures, it has universal operability in actual engineering projects.

[0014] The following further details the specific implementation modes of the present utility model in conjunction with the drawings. These implementation modes are only used to illustrate the present utility model and are not intended to limit the present utility model.

[0015] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0016] Such as Figures 1 to 2As shown in the figure, a structure in which a hoisting opening also serves as a pressure relief opening is provided. A vertical shaft 2 is formed by opening a hole in the basement roof 1. The vertical shaft 2 extends upward from the basement roof 1 and serves as both a hoisting opening and a pressure relief opening. An activity beam 3 is provided at the top of the vertical shaft 2. The two ends of the activity beam 2 are placed on the vertical shaft. A hoisting hole cover plate 5 is provided on one side of the activity beam 2, and a pressure relief cover plate 6 is provided on the other side. The hoisting hole cover plate 5 and the pressure relief cover plate 6 jointly cover the top of the vertical shaft 2. The activity beam 3 is not fixedly connected to the vertical shaft 2 but is only placed on the vertical shaft 2 and can be removed or reset at any time. A protruding corbel or a concealed beam can be provided inside the well wall of the vertical shaft 2 as a support for the activity beam 3. The activity beam 3 can be placed on the above-mentioned corbel or concealed beam. Of course, vertical grooves can also be directly opened on the well wall, and the two ends of the activity beam 3 are inserted into the grooves.

[0017] The hoisting opening is only used when underground equipment needs to be repaired or replaced. In normal times, it can be concealed by covering soil 12 or other means. Therefore, the hoisting hole cover plate 5 is generally lower than the outdoor ground. The pressure relief opening is convenient for starting or being blasted. The pressure relief cover plate 6 is made of lightweight materials and should not be covered by other heavy decorative objects. The four walls of the shaft need to be higher than the outdoor ground for flood prevention requirements. Therefore, as Figure 1 and Figure 2 shown, the elevation of the pressure relief cover plate 6 is higher than that of the hoisting hole cover plate 5. A concave opening is provided on the activity beam 3, and the hoisting hole cover plate 5 is placed on the concave opening and the groove on the well wall of the vertical shaft 2. The waterproof measures are as follows: The hoisting hole cover plate is made of self-waterproof concrete structure. A foam caulking agent 9 is vertically filled between the hoisting hole cover plate and the well wall groove, and a rubber cushion plate 10 is provided below. A cushion beam 7 is provided on the activity beam 3, and a supporting beam 8 is provided between the cushion beam 7 and the well wall of the raised vertical shaft 2. The supporting beam 8 supports the pressure relief cover plate 6. The pressure relief cover plate 6 is arranged on the supporting beam 8. The pressure relief cover plate 6 is preferably a embossed steel plate with a thickness of not more than 5 mm. It bends downward along one side of the pressure relief opening and extends to cover outside the cushion beam 7, and bends downward along the other side and extends to cover outside the well wall of the vertical shaft 2. The embossed steel plate and the cushion beam 7 and the well wall are filled with a waterproof sealant 11.

[0018] When pressure relief is required, the pressure relief cover plate is bounced open to open the pressure relief opening. When equipment hoisting is required: Remove the pressure relief cover plate 6, dig out the covering soil 12, then remove the hoisting hole cover plate 5, and then remove the activity beam 3 with the cushion beam 7. At this time, the entire vertical shaft 2 serves as an equipment hoisting channel to meet the transportation of large equipment.

[0019] The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
