Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building engineering, and specifically is a design of underground parking frame system about compound beam. BACKGROUND

[0002] In modern urban construction, underground parking has become an essential facility for residential, commercial and public buildings. To meet the needs of urban construction development, the design of underground parking should meet the basic requirements of applicability, safety, hygiene, economy, environmental protection and energy saving. Due to the mutual constraints of the above requirements, the maximum satisfaction of the above requirements is the selection and optimization process of designers for each requirement.

[0003] The frame system and pipeline arrangement of underground parking have a great influence on the layer height, aesthetic comfort and cost control of underground parking. The layer height of underground parking is determined by the net height of the parking area, the pipeline layer and the structure layer. According to the existing specifications and standards, the net height of the parking area for parking micro cars and small cars in the underground parking cannot be less than 2.2 meters. The layer height of the traditional underground parking is the height formed by the superposition of the net height of the parking area, the structure layer and the pipeline arrangement layer, so that the minimum layer height of the underground parking is usually nearly 4 meters. Under the premise of ensuring the net height of not less than 2.2 meters, there is still a lot of optimization space for the layer height occupied by the structure layer and the pipeline arrangement layer. Under the premise of trying to meet the more reasonable structure of underground parking and the comfortable and beautiful use scene, how to reduce the layer height, reduce the excavation amount and reduce the construction cost is the unremitting pursuit of designers in this industry, and is also the goal to be achieved by the utility model.

[0004] In recent years, designers have also been trying and exploring various attempts for the above goal, and there are not less than dozens of patents, such as: 1, CN 221878544 U; 2, CN 220035725 U; 3, CN 221118557 U; 4, CN 217735026 U; 5, CN 218375620 U; 6, CN 214696091 U; 7, CN 216196972 U; 8, CN 213597028 U; 9, 213898338 U; 10, CN 213927722 U; 11, CN 214424152 U; 12, CN 222101639 U; 13, CN 216644474 U; 14, CN 216196974 U; 15, CN 215717631 U; 16, CN 212613999 U.

[0005] From the above patent content, it is not difficult to see that the underground parking lot is generally used in two ways to reduce the floor height: one is to change the structure or arrangement of the frame beam, as in patents 1-11 above, to free up space for pipeline layout, so that the pipeline does not occupy or occupies less floor height space, achieving the purpose of reducing the floor height. But this kind of design mostly deteriorates the stress condition of the original frame beam, in order to compensate for the adverse effect on the stress condition of the frame beam, the strength of the frame beam is also strengthened, which increases the construction cost of the frame beam; the second is to design a separate space for installing pipelines, so that the pipeline layout does not occupy or occupies less floor height space, thereby reducing the floor height, but this kind of design increases the building space and the building area of the underground parking lot, also increasing the construction cost. Utility model content

[0006] In view of the above problems, the utility model is a frame system of an underground parking lot with a compound beam, which is established by using the special structure and arrangement of the compound beam under the premise of more reasonable stress condition of the compound beam, so that the pipeline layout does not separately occupy or occupies less floor height space, thereby reducing the floor height and the construction cost of the frame beam itself.

[0007] The technical scheme adopted by the utility model is:

[0008] A frame system of an underground parking lot with a compound beam, comprising a parking area, a non-parking area, a wall, an upper cover plate, a lower bottom plate, a stand column, a frame beam and a pipeline, wherein the upper cover plate, the lower bottom plate and the wall enclose an internal space of the underground parking lot and are connected to the stand column and the frame beam to form the frame system of the underground parking lot.

[0009] The parking area is composed of a parking space and a traffic lane; the parking space is composed of the size of the parked vehicle and the distance required around the parked vehicle; the traffic lane is a road space for vehicles to drive and pass in the underground parking lot to realize the connection between the parking space area and different areas of the underground parking lot; the non-parking area is composed of an area that cannot be parked by vehicles, a lower space area of the frame beam adjacent to the parking space area and having the same length direction as the parking direction of the parking space area, and an area that is artificially set to not be parked by vehicles.

[0010] The parking direction is the direction formed by the connection line from the vehicle head to the vehicle tail when the vehicle is parked, or the direction in which the vehicle head faces.

[0011] The frame beam comprises a solid beam and a compound beam; the frame beam above the parking space and the frame beam above the traffic lane are both solid beams; the frame beam above the non-parking area and needing to pass through the pipeline is a compound beam.

[0012] Further, the height difference between the vertical height L1 of the compound beam and the vertical height L2 of the solid beam is not greater than 1650mm.

[0013] Further, at least one through-beam hole is arranged on each of the compound beams, and the pipeline is arranged in the through-beam hole.

[0014] Further, the vertical height L3 of the through-beam hole is greater than 200mm and less than 4 / 5 of the vertical height L1 of the compound beam where the through-beam hole is arranged; and the width K of the through-beam hole is greater than 400mm and less than 4 / 5 of the length of the compound beam where the through-beam hole is arranged.

[0015] Further, the underground parking lot frame system at least comprises an underground layer.

[0016] The beneficial effects of the utility model are as follows:

[0017] (1) The net height of the parking area of the underground parking lot is mainly determined by the lower edge height of the solid beam and the pipeline arrangement mode, and is irrelevant to the lower edge height of the compound beam. Specifically, the lower space of all the compound beams is not used for parking vehicles, that is, the lower space of the compound beam is a non-parking area. According to the existing specification, the non-parking area is not limited in the minimum height, that is, the lower edge height of the compound beam is not limited by the minimum net height of the parking area required by the specification, so that the vertical height of the compound beam can be increased and the through-beam hole can be arranged on the compound beam. In this way, the stress condition of the compound beam is improved, and the material consumption of the compound beam is reduced.

[0018] Meanwhile, by the design of the utility model, under the premise of meeting the economy and strength of the compound beam, the height difference between the vertical height L1 of the compound beam and the vertical height L2 of the solid beam and the size range of the height L3 and the width K of the through-beam hole are limited, the vertical height of the compound beam is moderately increased, the strength of the compound beam is also increased, the compound beam can be used as the main beam to increase the span of the compound beam as much as possible, and the span of the solid beam in the same direction which is connected to the compound beam through the stand column is correspondingly reduced. In this way, the stress condition of the solid beam is also improved, and the height and material consumption of the solid beam are reduced.

[0019] (2) The frame system established by the differential design and layout of the solid beam and the compound beam structure improves the stress condition of the compound beam and the solid beam, reduces the height and material consumption of the solid beam, and also reduces the total height of the underground parking lot, so that the construction cost of the underground parking lot is greatly reduced.

[0020] (3) By the design of the compound beam, the pipeline is arranged through the through-beam hole in the compound beam, so that the pipeline arrangement is concentrated, the space of the layer height is not occupied or excessively occupied due to the pipeline arrangement, the purpose of reducing the layer height of the entire underground parking lot is achieved. At the same time, the pipeline arrangement is beautiful and regular, and the use scene of the underground parking lot is more comfortable. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings. Example 1:

[0035] A duplex beam underground parking garage frame system includes a parking area, a non-parking area, walls 3, an upper cover 4, a lower base slab 5, columns 8, frame beams, and pipelines. The upper cover 4, lower base slab 5, and walls 3 enclose the internal space of the underground parking garage and mutually support and connect with the columns 8 and frame beams to form the underground parking garage frame system. The underground parking garage frame system includes at least one underground level.

[0036] like Figures 1-3 As shown, the parking area consists of parking space area 1 and driveway 2. Parking space area 1 refers to the parking space divided for parking vehicles, which is composed of the size of the vehicle itself plus the distance required around the parked vehicle. The driveway is the road space for vehicles to drive and pass through the underground parking lot, so as to realize the entry and exit of vehicles into parking space area 1 and connect different areas of the underground parking lot. The parking method is perpendicular or parallel. When the vehicle is parked, the direction formed by the line connecting the front and rear of the vehicle or the direction in which the front of the vehicle is facing is the parking direction of parking space area 1.

[0037] like Figure 1 As shown, the non-parking area is the area outside the parking area, consisting of an area 1501 where vehicles cannot stop, a space area 1502 under the frame beam that is adjacent to the parking area and whose length direction is consistent with the parking direction of the adjacent parking area, and an area 1503 where vehicles are not allowed to stop.

[0038] like Figure 3 As shown, the frame beams include solid beams 7 and composite beams 6. The frame beams above the parking space area 1 and the driveway 2 are both solid beams 7; the frame beams above the non-parking area that require pipelines to pass through are composite beams 6.

[0039] like Figures 4-6As shown, the composite beam 6 is provided with a beam-penetrating hole 9, and a pipeline is horizontally arranged in the beam-penetrating hole 9, which includes any one or any combination of a ventilation duct 10, a cable bridge 11, a fire hydrant duct 12, a dry pipe 13, and other pipelines 14, i.e. heating and ventilation system ducts, domestic water system ducts, etc.

[0040] As shown in FIG. 1, the composite beam 6 is arranged in the frame system of the underground parking lot. Figures 4-6 As shown, the height difference between the vertical height L1 of the composite beam 6 and the vertical height L2 of the solid beam 7 is not greater than 1650 mm.

[0041] As shown in FIG. 1, the composite beam 6 is arranged in the frame system of the underground parking lot. Figures 4-6 As shown, at least one beam-penetrating hole 9 is provided on each composite beam 6. The beam-penetrating hole 9 is horizontally through the composite beam 6 in a transverse direction, or the beam-penetrating hole 9 is horizontally through the composite beam 6 in a direction perpendicular to the parking direction of the adjacent parking area 1.

[0042] As shown in FIG. 1, the composite beam 6 is arranged in the frame system of the underground parking lot. Figure 7 As shown, the beam-penetrating hole 9 is provided on the upper edge of the composite beam 6, and the composite beam 6 and the upper cover plate 4 form an integrated structure after construction, thereby ensuring the stability and sufficient bearing capacity of the overall frame system.

[0043] As shown in FIG. 1, the composite beam 6 is arranged in the frame system of the underground parking lot. Figures 8-9 As shown, the beam-penetrating hole 9 is provided on the middle part of the composite beam 6, and the side wall of the beam-penetrating hole 9 is not connected to the stand column 8 under the condition of ensuring the bearing capacity of the composite beam 6.

[0044] As shown in FIG. 1, the composite beam 6 is arranged in the frame system of the underground parking lot. Figure 9 As shown, under the premise of ensuring the stability and sufficient bearing capacity of the overall frame system, the cross-sectional shape, size and number of the beam-penetrating hole 9 are determined according to the actual needs of pipeline installation. The vertical height L3 of the beam-penetrating hole 9 is greater than 200 mm and less than four-fifths of the vertical height L1 of the composite beam 6 where the beam-penetrating hole 9 is located, and the width K of the beam-penetrating hole 9 is greater than 400 mm and less than four-fifths of the length of the composite beam 6 where the beam-penetrating hole 9 is located, thereby ensuring the pipeline passing through and the bearing capacity of the beam body.

[0045] In the frame beam in the non-parking area and not needing the pipeline passing through, any one of the solid beam 7 and the composite beam 6 is provided according to actual needs. Embodiment 2:

[0046] As shown in FIG. 1, the composite beam 6 is arranged in the frame system of the underground parking lot. Figure 10 As shown, in a composite beam underground parking lot frame system, the parking area 1 with three parking spaces arranged in front and back directions in parallel is changed to a parking area 1 with two parking spaces arranged in parallel. Embodiment 3:

[0047] As shown in FIG. 1, the composite beam 6 is arranged in the frame system of the underground parking lot. Figure 11 As shown, in a composite beam underground parking lot frame system, the main parking mode adopts a parallel type.

[0048] The net height of the parking area of the underground parking lot is mainly determined by the lower edge height of the solid beam 7 and the pipeline arrangement mode, and is irrelevant to the lower edge height of the compound beam 6. Specifically, all the lower space of the compound beam 6 is not for parking vehicles, that is, the lower space of the compound beam 6 is a non-parking area, and according to the existing specification, the non-parking area is not limited to the minimum height, that is, the lower edge height of the compound beam 6 is not limited by the minimum net height of the parking area required by the specification, and the lower edge height of the compound beam 6 can be designed to be lower, even lower than the minimum net height of the parking area required by the specification, so that the vertical height of the compound beam 6 can be increased and the beam-penetrating hole 9 can be arranged on the compound beam 6, so that the stress condition of the compound beam 6 is improved, and the material consumption of the compound beam 6 is reduced.

[0049] Meanwhile, through the design of the utility model, under the premise of meeting the economy and strength of the compound beam 6, the height difference between the vertical height L1 of the compound beam 6 and the vertical height L2 of the solid beam 7 and the size range of the height L3 and the width K of the beam-penetrating hole 9 are limited, the vertical height of the compound beam 6 is moderately increased, and the strength of the compound beam 6 is also increased, the compound beam 6 can be used as a main beam to increase the span as much as possible, and the span of the solid beam 7 in the same direction relative to the post 8 is correspondingly reduced, so that the stress condition of the solid beam 7 is improved, and the height and material consumption of the solid beam 7 are reduced.

[0050] In the design scheme of the present application, most of the main pipelines and pipelines are arranged horizontally through the beam-penetrating hole 9 in the compound beam 6, and the lower edge height of the main pipelines and most of the pipelines is easily ensured to be not lower than or slightly lower than the lower edge height of the solid beam 7, so that the layer height of the entire underground parking lot is reduced. At the same time, since most of the main pipelines and pipelines are concentratedly arranged horizontally through the beam-penetrating hole 9 in the compound beam 6, the pipeline arrangement is beautiful and regular, and the use scene of the underground parking lot is more comfortable.

[0051] The above description of the disclosed embodiments is a technical solution that can be implemented or used by a person skilled in the art. Various modifications of these embodiment schemes and individual names, and to the skilled person in the art, the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0052] In the utility model, the term "solid beam" is only used to distinguish and describe the compound beam, which is a simplified description of the utility model, and does not indicate or imply the structure of the solid beam, so it cannot be understood as a limitation of the utility model.

[0053] The terms "front", "back", "left", "right", "middle", "inner", "outer", "upper", "lower" and the like in the description of the utility model indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the structure or device referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
