Description

Skip-floor garage and building

Technical Field

The present disclosure relates to a duplex garage and a building.

Background

A building assembled from prefabricated components at a worksite is referred to as an assembled building. Although the building speed of the building is improved by the assembled building, compared with the traditional building, the building has higher manufacturing cost, certain popularization difficulty exists, the bearing capacity of the assembled cavity building structure is lost, and the bearing capacity is improved to break through urgently.

Detailed Description

The present disclosure is described in further detail below with reference to the drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant content and not limiting of the present disclosure. It should be further noted that, for convenience of description, only a portion relevant to the present disclosure is shown in the drawings.

In addition, embodiments of the present disclosure and features of the embodiments may be combined with each other without conflict. The technical aspects of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Unless otherwise indicated, the exemplary implementations/embodiments shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure may be practiced. Thus, unless otherwise indicated, features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present disclosure.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate like parts.

When an element is referred to as being "on" or "over", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. For this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" higher "and" side (e.g., as in "sidewall"), etc., to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below" … … can encompass both an orientation of "above" and "below". Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, when the terms "comprises" and/or "comprising," and variations thereof, are used in the present specification, the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof is described, but the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof is not precluded. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximation terms and not as degree terms, and as such, are used to explain the inherent deviations of measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art.

Fig. 1 is a schematic structural view of a duplex garage according to one embodiment of the present disclosure.

As shown in fig. 1, the duplex garage of the present disclosure may include a top panel 110, a bottom panel 120, at least one intermediate panel 130, and an exterior wall 150. Those skilled in the art will appreciate that fig. 1 is only a portion of a duplex garage.

The top plate 110 and the bottom plate 120 are spaced apart from each other by a predetermined distance, which may be determined according to the number of the intermediate plates 130, for example, as shown in fig. 1, when the intermediate plates 130 are one layer, the distance between the top plate 110 and the bottom plate 120 may be 5-6m; accordingly, although the present disclosure is not illustrated by the drawings, when the intermediate plates 130 are two-layered, there is a distance of about 2-3m between the two intermediate plates 130, and accordingly, the distance between the top plate 110 and the bottom plate 120 may be set to 7-9m.

The roof 110 is formed as the top of the skip-floor garage 100, and when the skip-floor garage 100 is formed as an underground parking garage, an overburden layer may be disposed above the roof 110; when the skip-floor garage 100 is formed as an above-ground parking garage, the top plate 110 is formed as an uppermost portion of the skip-floor garage 100. More preferably, the top plate 110 may be provided with a lighting vent hole, etc., and the lighting vent hole may be formed above the hollowed-out area 180, for example, formed directly above or obliquely above the hollowed-out area 180. Of course, the skip-floor garage 100 may also be formed as a semi-underground semi-above-ground garage.

The earthing layer is internally provided with a gas flowing pipeline, and the air flue pipe 400 can be communicated with the gas flowing pipeline, so that air enters the air flue pipe 400 through the gas flowing pipeline, or flue gas in the duplex garage 100 enters the air flue pipe 400 and is discharged through the gas flowing pipeline.

Specifically, the air flue pipe 400 may be connected to a fan, and accordingly, the fan is connected to the air flow pipe, that is, the air flow pipe is in communication with the air flue pipe 400 through the fan, so that the flue gas in the skip-floor garage 100 is discharged to the outside of the skip-floor garage 100 through the fan, or fresh air outside the skip-floor garage 100 is delivered to the inside of the skip-floor garage 100 through the fan.

Those skilled in the art will appreciate that when the jump garage of the present disclosure is formed as an above-ground garage, roof 110 may not be included.

The floor 120 is formed as the bottom of the duplex garage 100, and a parking space is provided on the floor 120, for example, a space between the floor 120 and the intermediate plate 130 adjacent to the floor 120 is formed as the above-described parking space, in which at least one bottom travel lane for vehicle passing and a bottom parking space provided on at least one side of the bottom travel lane so that a vehicle can be parked in the bottom parking space are provided.

In the present disclosure, the floor panel 120 may be formed by concrete casting, and the bottom parking space, the bottom driving lane, etc. may be formed by drawing on the floor panel 120 according to an actual item.

The intermediate plate 130 is disposed between the top plate 110 and the bottom plate 120. In the present disclosure, the intermediate plate 130 may be provided at least one in a vertical direction, for example, when the number of the intermediate plates 130 is one, a skip-floor garage 100 having two parking floors is formed. When the number of the intermediate boards 130 is two, a skip-floor garage 100 having three parking floors is formed. Of course, the middle plate 130 may be provided in three, four, five, etc. numbers.

That is, when the number of the intermediate plates 130 of the present disclosure is two or more, these intermediate plates 130 are disposed in a state of being arranged in the height direction.

Each intermediate plate 130 includes: the parking system comprises at least one intermediate driving lane for the passage of vehicles and intermediate parking spaces which are arranged on at least one side of the intermediate driving lane, wherein vehicles can also be parked in the intermediate parking spaces.

In the present disclosure, when the intermediate plates 130 are provided in at least two, the intermediate plates 130 may be disposed in parallel; for example, the intermediate plates 130 are each disposed in a certain horizontal plane; more preferably, the middle plate 130 may be parallel to the top plate 110 and the bottom plate 120, i.e., the top plate 110, the bottom plate 120, and the middle plate 130 are all disposed in a certain horizontal plane.

Of course, the middle plate 130, the top plate 110 and the bottom plate 120 may not be parallel to each other, and may be selectively arranged according to the specific circumstances of the project by those skilled in the art.

In the present disclosure, when the middle plate 130 is one, the distance between the middle plate 130 and the bottom plate 120 is the same as the distance between the middle plate 130 and the top plate 110 or the difference is within a preset range, so that the two parking levels have substantially the same level.

On the other hand, when the number of the intermediate plates 130 is at least two, the distance between the intermediate plates 130 and the bottom plate 120, the distance between two adjacent intermediate plates 130, and the distance between the intermediate plates 130 and the top plate 110 are the same or substantially the same (i.e., the difference is within a preset range), so that the parking levels have substantially the same level height.

In the present disclosure, the bottom plate 120 and the top plate 110 are supported by the support columns 140, that is, the support columns 140 are disposed between the bottom plate 120 and the top plate 110. As an implementation form, the support columns 140 may be arranged in segments, for example, the support columns 140 may be arranged between the bottom plate 120 and the middle plate 130 to support the middle plate 130; accordingly, a support column 140 may also be provided between the middle plate 130 and the top plate 110 to support the top plate 110.

Preferably, the support columns 140 at different heights may be disposed on the same vertical line so that force can be directly transferred between the support columns 140.

The outer wall 150 is disposed between the top plate 110 and the bottom plate 120 and at least partially surrounds the intermediate plate 130, that is, when the outer wall 150 is formed in a ring-shaped structure, the outer wall 150 may enclose a closed space together with the top plate 110 and the bottom plate 120, or when the outer wall 150 has an opening through which a vehicle may enter the skip-floor garage from the outside, the outer wall 150 may enclose a space together with the top plate 110 and the bottom plate 120.

In the present disclosure, the skip-floor garage may further include an access lane directly or indirectly connected to the bottom plate 120 or the middle plate 130, so that the vehicle enters the skip-floor garage through the access lane.

The duplex garage disclosed by the disclosure comprises at least one hollowed-out area 180, wherein the hollowed-out area 180 is positioned near the middle plate 130, and the upper space and the lower space of the middle plate 130 are communicated through the hollowed-out area 180; more specifically, the hollowed-out area 180 is located at a lateral side of the middle plate 130 in the horizontal direction.

In one embodiment, the number of the intermediate plates 130 may be more than two, and the two intermediate plates 130 may be at the same horizontal height or have a certain height difference in the vertical direction, where a certain interval exists between the two intermediate plates 130 in the horizontal direction, and the hollowed-out area 180 is formed by the interval.

In another embodiment, a hollowed-out area 180 is formed between the middle plate 130 and the outer wall 150, that is, the middle plate 130 is not directly connected to the outer wall 150 in a partial area, so that the hollowed-out area 180 is formed between the middle plate 130 and the outer wall 150.

Fig. 1 shows only two hollowed-out areas 180, but it will be apparent to those skilled in the art that the number of hollowed-out areas 180 may be set to be plural in accordance with the size of the area of the garage in the whole duplex garage.

In the present disclosure, the fireproof space above the hollowed-out area 180 and the fireproof space below the hollowed-out area 180 are communicated through the hollowed-out area 180 to form a cross-layer fireproof partition or fireproof unit.

The duplex garage of the present disclosure further includes a transverse sealing device 200, where the transverse sealing device 200 is configured to selectively seal at least a portion of the hollowed-out area 180; when fire and/or smoke is generated in the duplex garage: the hollow-out area is closed by the transverse closing device 200, so that the fireproof space above the hollow-out area 180 and the fireproof space below the hollow-out area 180 are in different fireproof partitions or fireproof units.

That is, when the jump garage disclosed by the disclosure is used, in a normal state, the transverse sealing device 200 cannot seal the hollowed-out area 180, so that the jump garage is more attractive due to the hollowed-out area 180, and meanwhile, the pipeline arrangement in the jump garage is also facilitated. On the other hand, when a fire occurs, the hollow area 180 may be closed by the transverse closing device 200, so that the space above and below the hollow area 180 is not communicated, and accordingly, different fireproof partitions or fireproof units are correspondingly formed above and below the hollow area 180.

In the present disclosure, selectively closing the hollowed-out area 180 means that the lateral closing device 200 may be formed as a movable device, so that when there is a fire, the lateral closing device 200 can close the hollowed-out area 180 such that a fire-proof space above the hollowed-out area 180 and a fire-proof space below the hollowed-out area 180 are in different fire-proof partitions or fire-proof units. At this time, when a fire occurs, the hollowed-out area 180 can be closed by the lateral closing device 200 to block the fire from spreading to other fireproof partitions or fireproof units.

Accordingly, when no fire occurs, the transverse sealing device 200 at least makes part of the hollow area 180 not sealed, and connects the fireproof space above the hollow area 180 and the fireproof space below the hollow area 180 through the hollow area 180.

That is, whether or not the lateral closure device 200 is provided determines how the fire zones or units are partitioned. When the transverse sealing device 200 exists, as long as the transverse sealing device 200 can seal the hollow area 180, even if the transverse sealing device 200 is not in a state of sealing the hollow area 180, the fireproof space above the hollow area 180 and the fireproof space below the hollow area 180 also belong to different fireproof partitions or fireproof units, so that the number of vertical separating devices (capable of separating each parking space into different fireproof partitions or fireproof units) arranged in each parking space can be reduced, and the construction cost of the duplex garage is reduced.

In the present disclosure, the lateral sealing device 200 is disposed on the middle plate 130 or the outer wall 150 near the hollowed-out area 180, so that the lateral sealing device 200 can seal the hollowed-out area 180.

Preferably, the lateral closure device 200 is selected from at least one of a lateral roller blind, a lateral pleated blind, a lateral roller blind, a gravity fire curtain, a slope gravity fire curtain, and a fire resistant lateral cover plate. That is, for the same hollowed-out area 180, one of the transverse roller shutter, the transverse folding shutter, the transverse roller shutter, the gravity fireproof shutter, the slope gravity fireproof shutter and the fireproof transverse cover plate can be selected, and a plurality of the transverse roller shutter, the transverse folding shutter, the transverse roller shutter, the gravity fireproof shutter, the slope gravity fireproof shutter and the fireproof transverse cover plate can also be selected.

Fig. 2 is a schematic structural view of a duplex garage according to another embodiment of the present disclosure.

As shown in fig. 2, the structure of the duplex garage is substantially the same as that of fig. 1, except that the transverse closing device 200 is implemented by a slope gravity fire curtain, so that the slope gravity fire curtain is stored to one side of the hollow area under the condition that no fire or smoke is generated, and the hollow area is in an open state. In the event of a fire or smoke, the sloping gravitational fire curtain is released, thereby closing the hollowed-out area 180.

In the present disclosure, as shown in fig. 1, a portion of the hollowed-out area 180 may also be closed by a vertical closing device 500. For example, the device for closing the hollowed-out area 180 may be all the transverse closing device 200, all the vertical closing device 500, or part of the transverse closing device 200 and part of the vertical closing device 500.

Taking fig. 1 as an example, the duplex garage includes two hollowed-out areas 180, one of the two hollowed-out areas 180 is closed by a transverse closing device 200, and the other is closed by a vertical closing device 500.

The vertical sealing device 500 is configured to selectively at least partially enclose a portion of the hollowed-out area 180 in the hollowed-out area 180; and the vertical sealing device 500 forms a smoke storage corridor 510, namely, a space surrounded by the smoke storage corridor 510, namely, the vertical sealing device, and the space is communicated with the hollowed-out area 180. When a fire occurs in the skip-floor garage 100 to generate smoke, at least part of the smoke flows to the smoke storage gallery 510 and is discharged to the outside of the skip-floor garage 100 through the wind-smoke pipe 400 communicating with the smoke storage gallery 510.

That is, when flue gas is generated inside the duplex garage: the hollow area 180 is closed by the transverse closing device 200, so that the fireproof space above the hollow area 180 and the fireproof space below the hollow area 180 are in different fireproof partitions or fireproof units; and a smoke storage gallery 510 is formed by the vertical closing means 500, at least part of the smoke flows to the smoke storage gallery 510, and is discharged to the outside of the skip-floor garage through the wind smoke pipe 400 communicating with the smoke storage gallery 510.

That is, on the one hand, by the vertical sealing device 500, the fireproof space above the middle plate 130 where the hollowed-out area 180 is located and the fireproof space below the middle plate belong to different fireproof partitions or fireproof units, and at this time, the fireproof partitions of each layer in the duplex garage 100 are similar/identical to the fireproof partitions of the flat layer. On the other hand, the enclosure space of the vertical closing device 500 has an opening area, so that the opening area of the enclosure space of the vertical closing device 500 is used to connect the fireproof space above the middle plate 130 where the hollowed-out area 180 is located and the fireproof space below the middle plate 130 where the hollowed-out area 180 is located, so that the fireproof space above the middle plate 130 where the hollowed-out area 180 is located and the fireproof space below the middle plate are the same fireproof partition or fireproof unit, and therefore a cross-layer fireproof partition or fireproof unit is formed inside the duplex garage 100.

In other words, by the vertical closing device 500, the smoke storage lane 510 and the fire prevention space communicating with the smoke storage lane 510 belong to the same fire prevention partition or fire prevention unit.

When the transverse sealing device 200 and the vertical sealing device 500 of the present disclosure are used, only the transverse sealing device 200 or only the vertical sealing device 500 may be provided for the same hollow area 180; it should be appreciated by those skilled in the art that, for the same hollow area 180, the transverse sealing device 200 and the vertical sealing device 500 may be provided at the same time, where the transverse sealing device 200 may seal a partial area of the hollow area 180, and correspondingly, the vertical sealing device 500 may seal (encircle) a partial area of the hollow area 180, thereby, by combining the transverse sealing device 200 and the vertical sealing device 500, sealing of the entire hollow area 180 is achieved.

On the other hand, when the opening area exists in the enclosure space of the vertical enclosure device 500, the opening area of the enclosure space of the vertical enclosure device 500 is used to connect the fireproof space and/or the smoke storage gallery outside the enclosure space of the vertical enclosure device 500, so that the fireproof space above the hollowed-out area 180 and the fireproof space below the hollowed-out area 180 belong to the same fireproof partition or fireproof unit.

More preferably, as shown in fig. 10, the lateral sealing device 200 may be disposed on the cantilever plate 160, and of course, the lateral sealing device 200 may also be directly disposed on the intermediate plate 130, and in this case, the intermediate plate 130 may not be disposed on the cantilever plate 160.

As shown in fig. 11, the shower system 700 can also be secured to the intermediate plate 130; in one embodiment, the spray pipes 710 of the spray system 700 may be fixed to the middle plate 130 around the hollowed-out area 180, and thus, at least a portion of the spray system 700 may be located below the lateral sealing device 200, and at least one spray head 720 of the spray system 700 may spray the fire fighting liquid toward the lateral sealing device 200, downward, and/or obliquely downward.

Also, the number of the recess structures 1004 may be set according to the height of the frame 1001, and in a preferred embodiment, the recess structures 1004 are provided in two in the height direction, and accordingly, the two recess structures 1004 are formed with three protrusion structures.

At least one end of the rib structure 1002 is attached to the side wall of the housing 1001. In a preferred embodiment, the two ends of the rib structure 1002 are attached to two opposite side walls of the housing 1001, respectively. In the present disclosure, the connection position between the rib structure 1002 and the housing 1001 is not limited, and it may be connected to a different position on the inner surface of the housing 1001.

That is, the space structures are formed by the rib structures 1002, and accordingly, the rib structures 1002 may be orthogonal, diagonal, or arc-shaped intersecting, such that the space structures have one or more of square, rectangular, diamond, triangular, circular, arc, or polygonal shapes in plan view.

In a preferred embodiment, the cross section of the rib structure 1002 may be different in width from top to bottom or equal in width from top to bottom, wherein the different widths are that the rib structure 1002 has a small upper portion and a large lower portion, or a large upper portion and a small lower portion.

As shown in fig. 23, the assembled cavity building structure includes the prefabricated cavity floor 1000, the rib beam 2000 and the laminated layer 3000 described below.

Of course, if the strength of the connection of the prefabricated cavity floor 1000 and the rib beam 2000 is sufficient, the lamination layer 3000 may not be provided.

The rib beam 2000 is disposed at or near a spaced area between two adjacent prefabricated cavity floors 1000. In the process of manufacturing the fabricated cavity building structure, adjacent prefabricated cavity floors 1000 are spaced apart by a predetermined distance or a predetermined width, so that a predetermined space is formed between the prefabricated cavity floors 1000, and concrete is poured into the predetermined space to form the rib beam 2000. At this time, the rib beam 2000 can form a mechanical connection with the outer circumferential surface of the frame 1001 of the prefabricated cavity floor 1000, so that the fabricated cavity building structure has better mechanical properties.

On the other hand, since the prefabricated cavity floor 1000 has the concave structure 1004, the rib beam 2000 formed by casting has the convex structure inserted into the concave structure 1004, thereby allowing better connection strength between the prefabricated cavity floor 1000 and the rib beam 2000.

In the present disclosure, when the connectors 1003 are disposed at the periphery of the prefabricated cavity floor 1000, at least a portion of the connectors 1003 are located inside the rib 2000, and thus, the connectors 1003 of the prefabricated cavity floor 1000 can act as at least a portion of the stress reinforcement or the construction reinforcement of the rib 2000. Of course, the connection members 1003 may be connected to each other at the position of the rib beam 2000, for example, the connection members 1003 extending from two rib structures 1002 along the longitudinal direction are connected at the rib beam, so that the rib structures at both sides of the rib beam are substantially abutted and extended, thereby being capable of continuously receiving force. Correspondingly, the frame body is also in the length direction, and the integral prefabricated cavity floor system has a superior structure system with bidirectional stress and larger bearing capacity.

For example, the connectors 1003 of the adjacent prefabricated cavity floors 1000 may be directly connected or connected by a reinforcing member 2001 provided inside the rib 2000, wherein the reinforcing member 2001 may be a reinforcing bar provided along the length direction of the rib 2000, the ends of the connectors 1003 may be formed with hooks, and the hooks may be hooked on the reinforcing member 2001, or mechanically connected to each other, or welded, etc., so that the connectors 1003 of the adjacent prefabricated cavity floors 1000 may be more closely connected to each other, and at the same time, the reinforcing member 2001 may be formed as a skeleton of the rib 2000 and the rib may have a strong bending moment resistance, a greater bearing capacity, and a higher strength, whereby the prefabricated cavity floor structure with the rib may also have a greater bearing capacity and a higher strength as a whole.

The rib beam structure or stronger T-shaped rib beam structure (namely, the rib beam 2000 and the laminated layer 3000 together form a T-shaped section with better mechanical property) has the function of enhancing the overall bearing capacity of the prefabricated cavity floor system, meanwhile, the rib structures between the prefabricated cavity floors can be butted to form a full-length force transmission structure, and the rib structures and the rib beams in the other direction cooperate to form a more superior bidirectional prefabricated cavity floor system, wherein the laminated layer 3000 can also be called a flange.

In other words, compared with the situation that there is no reinforcing member between the prefabricated cavity floor and the prefabricated plates, that is, the situation that there is no bearing capacity between the prefabricated plates, one key point of the present disclosure is to integrally mold the post-molded rib beam and the reinforcing member into an important structure, which can bear about half of the load, so as to form a T-shaped rib beam, which has a larger bearing capacity, is integrated with the prefabricated cavity floor, and can jointly bear nearly doubled load.

In a specific embodiment, the reinforcing member 2001 may be a plurality of reinforcing bars, which may be arranged in a plurality of rows in a vertical direction, and each row of reinforcing bars may include a plurality of reinforcing bars. In a preferred embodiment, each row of rebars may be connected to or anchored into another rib corresponding to another rib in the extension direction, or within an extreme wall, column or beam, thereby facilitating connection of connector 1003 to reinforcement member 2001. More preferably, when the reinforcing bars of a certain row of the reinforcing member 2001 include a plurality of reinforcing bars, the connector 1003 is connected to the reinforcing bar farthest therefrom, so that the connector 1003 can have the maximum anchoring length within the rib beam 2000, thereby improving the reliability of the anchoring connection and also improving the connection strength between the prefabricated cavity floor 1000 and the rib beam 2000.

In a preferred embodiment, the rib beam 2000 further comprises strapping members 2002, which strapping members 2002 are capable of interconnecting the reinforcement members 2001 and keeping the reinforcement members 2001 in a reasonable position until no concrete is poured.

In the present disclosure, the reinforcement member 2001 and the strapping member 2002 can be formed in the form of a mesh reinforcement or a cage reinforcement.

When the rib beam 2000 is formed, the lower surface of the rib beam 2000 is flush with the lower surface of the prefabricated cavity floor 1000. In other embodiments, the lower surface of the rib beam 2000 may be higher or lower than the lower surface of the prefabricated cavity floor 1000, as long as the connection strength between the rib beam 2000 and the prefabricated cavity floor 1000 is sufficient.

As shown in fig. 24, a cover plate 4000 is disposed above the prefabricated cavity floor 1000 of the fabricated cavity building structure, a lamination layer 3000 is at least disposed above the cover plate 4000, and the lamination layer 3000 and the rib beam 2000 are integrally formed by cast-in-place concrete. Accordingly, the deck 4000, the laminate 3000, and the rib 2000 are formed as an integral force-bearing structure when concrete is poured.

Although not shown in fig. 24, the fabricated cavity building structure of the present disclosure may include only the lamination layer 3000, and the cover plate 4000 is not disposed under the lamination layer 3000, and at this time, when the lamination layer 3000 is poured, a formwork may be disposed inside the prefabricated cavity building cover 1000, so that the lamination layer 3000 and the rib beam 2000 are formed into an integral stress structure by means of concrete pouring.

In the present disclosure, the stacked layer 3000 can connect the prefabricated hollow floor 1000 and the cover plate 4000, the cover plate and the rib structure, or the cover plate and the rib beam, wall or column to form an integral structure, so as to be stressed together.

Accordingly, in the present disclosure, a space is provided between the lower surface of the cover plate 4000 and the upper surface of the back cover plate 1007, thereby forming a cavity structure between the cover plate 4000 and the back cover plate 1007; on the other hand, when the fabricated cavity construction structure does not include the back cover plate 1007, the lower surface of the laminated layer is spaced apart from the back cover plate 1007, thereby forming a cavity structure between the laminated layer and the back cover plate.

In the present disclosure, as shown in fig. 24 and 25, the fabricated cavity building structure further includes a cover 4000, where the cover 4000 is disposed on the prefabricated cavity floor 1000 and at least partially covers the space structure surrounded by the frame 1001 and the rib structure 1002, and/or the rib structure 1002.

That is, the shape of the cover plates 4000 may be formed to be the same as, slightly smaller than, or slightly larger than the space structures, whereby each cover plate 4000 is capable of closing at least one space structure. Of course, the area of the cover plates 4000 may also be set large enough, and thus each cover plate 4000 can cover at least two space structures.

In a preferred embodiment, the cover 4000 as a whole can entirely cover the area enclosed by the frame 1001. Generally, the cover plates 4000 are not disposed across different prefabricated cavity floors 1000 because the rib beams 2000 are required to be formed at the locations where the prefabricated cavity floors 1000 are connected.

More preferably, when the fabricated cavity building structure includes the cover plate 4000, the lamination layer 3000 may not be provided; that is, the upper end of the prefabricated cavity floor 1000 is capped, the rib beam and/or the rib structure and the top of the frame body are connected and anchored with the cover plate by reinforcing steel bars, and the precast concrete is refilled to form a whole; accordingly, when the superposition layer 3000 is provided on the prefabricated cavity floor 1000, the superposition layer 3000 is formed at least above the prefabricated cavity floor 1000 by cast-in-place concrete.

In other words, the cover 4000 can be integrally connected with a rib structure, a beam, a wall, a column, etc. by providing reinforcing bars and/or post-cast concrete, and can be integrally stressed together.

As to the specific structure of the cover plate 4000, as shown in fig. 25, the cover plate 4000 includes a base 4001, the base 4001 may be made of reinforced concrete, and the shape of the base 4001 may be adapted to the shape of a space structure, for example, formed in a square shape or other shapes. Preferably, the area of the base 4001 is slightly larger than the area of the space structure, so that the base 4001 can be stably placed on the prefabricated cavity floor 1000.

In a preferred embodiment, the base 4001 may be formed to cover two or more space structures, and the base 4001 may be shaped to cover these space structures.

In some implementations, the perimeter of the base 4001 may not be provided with a connection 4002. However, it is preferable that the periphery of the base 4001 is provided with a connection portion 4002, wherein the connection portion 4002 may be formed by using a reinforcing bar, and at this time, a part of the connection portion 4002 is located inside the base 4001, and the other end of the connection portion 4002 is located outside the base 4001 and is formed as a free end.

In the present disclosure, the connection portions 4002 may be formed in a row, that is, provided in one in the thickness (height) direction of the base portion 4001, and these connection portions 4002 can be located on a certain plane or on a certain horizontal plane.

In the present disclosure, when the connection portion 4002 is provided at the periphery of the cover 4000 and the cover 4000 is provided to the prefabricated cavity floor 1000, at least a portion of the connection portion 4002 is located inside the rib 2000, whereby the connection portion 4002 of the cover 4000 can be anchored at the rib 2000. Of course, the connection parts 4002 may be connected to each other at the position of the rib 2000, for example, the connection parts 4002 of the adjacent cover plates 4000 may be directly connected or overlapped, or may be connected or overlapped by a reinforcement member 2001 provided inside the rib 2000, wherein the reinforcement member 2001 may be a reinforcing bar provided along the length direction of the rib 2000, an end of the connection part 4002 may be formed with a hook part, and the hook part may be hooked on the reinforcement member 2001, thereby enabling the connection parts 4002 of the adjacent cover plates 4000 to be connected to each other more reliably, and at the same time, the reinforcement member 2001 may also be formed as a skeleton of the rib 2000, and enabling the rib to have higher strength or bearing capacity.

In a specific embodiment, the reinforcing bars of the reinforcing member 2001 can also correspond to the positions of the connection portions 4002 of the cover plate 4000 so as to facilitate the connection of the connection portions 4002 with the reinforcing member 2001. More preferably, when the reinforcing bars of a certain row of the reinforcing member 2001 include a plurality of reinforcing bars, the connection portion 4002 is connected to the reinforcing bar farthest therefrom, so that the connection portion 4002 can have the maximum length within the rib beam 2000, thereby improving the anchoring reliability of the connection portion 4002.

That is, the part of the connection portion 4002 of the cover 4000 is connected to the rib 2000, and the part of the connection portion 4002 of the cover 4000 may be located above the frame 1001 or the rib structure 1002, and when the laminated layer 3000 is formed by casting concrete, the connection portion 4002 may be located in the laminated layer 3000.

In a preferred embodiment, as shown in fig. 16, 19 and 22, the frame 1001 and the rib structure 1002 are provided with connection bars 1005 at upper ends thereof, and as shown in fig. 24, the connection portion 4002 can be connected or anchored with the connection bars 1005, so that the cover plate 4000 can be integrated with the prefabricated cavity floor 1000 after the in-situ concrete is stacked.

More preferably, extension bars 3001 are further provided at upper positions of the frame 1001 and the rib structure 1002, for example, the extension bars 3001 can be provided in plurality and are fixed to the connection bars 1005 of the frame 1001 and/or the rib structure 1002, and at this time, the extension bars 3001 can be provided in the direction of the frame 1001 and/or the rib structure 1002, whereby the strength of the laminated layer 3000 can be improved.

In the present disclosure, the cover plate is prefabricated independently or may be replaced with a steel carrier plate. The gap exists between the cover plate and the back cover plate, so that a cavity is formed in the assembled cavity building structure, the dead weight of the assembled cavity building structure is reduced through the cavity, and the bearing capacity of the assembled cavity building structure is improved. Accordingly, when the fabricated cavity building structure does not include the cover plate, but includes only the lamination layer, there is also a gap between the lamination layer and the back cover plate, and at this time, the interior of the fabricated cavity building structure also forms a cavity.

The fabricated cavity building structure of the present disclosure can be used for floor or roof structures of above-ground or below-ground buildings, or for parking levels or roof structures of motorized or non-motorized garages.

Therefore, through the assembled cavity building structure disclosed by the invention, the construction speed of buildings such as an underground garage of a building can be greatly improved, and the dead weight of the assembled cavity building structure is lower, so that the assembled cavity building structure can bear larger bending moment while saving building materials, the construction cost is reduced, and the energy conservation and emission reduction are realized.

As shown in fig. 26, the fabricated cavity building structure may not include a laminated concrete layer on top of the cover plate, the cover plate spacers are integrally formed by cast-in-place reinforced concrete, and accordingly, the connection portion 4002 of the cover plate 4000 may be at least partially located inside the rib beam 2000, so that the cover plate 4000 and the rib beam 2000 are formed as an integral stress structure; also, in fig. 26, the lower surface of the rib 2000 is flush or substantially flush with the lower surface of the prefabricated cavity floor 1000.

That is, when the fabricated cavity building structure does not have a lamination layer, the top of the frame, the top of the rib structure and the rib beam are formed as one body by cast-in-place concrete, and accordingly, at least part of the connection portion 4002 of the cover 4000 is located in the one body, and the top of the frame, the top of the rib structure and the rib beam are connected as one body with the cover.

In the present disclosure, a connection position between two adjacent cover plates 4000 may be located above a rib structure 1002 of a prefabricated cavity floor 1000, at this time, an area between two cover plates 4000 may be poured with concrete and formed into a connection area, a connection portion 4002 of the cover plate 4000 and a connection bar 1005 of the prefabricated cavity floor 1000 may be located at least partially in the connection area, and the connection portion 4002 may be anchored or connected with the connection bar 1005, thereby forming an overall stress structure between the cover plate 4000 and the prefabricated cavity floor 1000.

Also, at least part of the rib beam 2000 is formed above the rib structure 1002 adjacent thereto, whereby the rib beam 2000 is formed as a T-shaped rib beam, whereby the prefabricated cavity floor 1000, the T-shaped rib beam and the cover plate 4000 are formed as an integral force-receiving structure therebetween.

Further, as shown in fig. 27, the fabricated cavity building structure may not include a laminated concrete layer on top of the cover plate, and the cover plate intervals are integrally connected by reinforced concrete cast-in-situ. Moreover, the lower surface of the rib beam 2000 extends beyond the lower surface of the prefabricated cavity floor 1000, thereby providing the rib beam 2000 with higher strength and correspondingly the fabricated cavity building structure with higher strength.

Under the condition that the material consumption is equal and the area is equal, compared with a solid plate, the prefabricated cavity floor system can greatly increase the section moment of inertia, further greatly improve the bending resistance, realize larger span or stronger bearing capacity, realize industrialized production, accelerate the construction speed, save a large amount of concrete in the cavity, and greatly lighten the structural dead weight, so that the prefabricated cavity floor system is assembled into a floor system structure, greatly improve the effective bearing capacity, greatly lighten the structural dead weight, greatly reduce the construction cost, realize large-scale industrialized production, quickly assemble at a construction site and greatly save the construction period.

In the present disclosure, when a lamination layer is present, the rib beam is integrally cast with the lamination layer, and the rib beam is formed as a T-shaped rib beam. More preferably, the rib beam, the overlapping layer and the cover plate are connected to form a concrete pouring integrated slab, namely the upper flange of the rib beam, so that a T-shaped rib beam with greatly improved mechanical properties is formed, and the T-shaped rib beam is provided with stress steel bars, so that a large amount of force can be shared.

When no lamination layer exists, cast-in-place concrete in the connection area of the rib beam and the cover plate forms a T-shaped rib beam with greatly improved mechanical property, and the T-shaped rib beam is provided with stress steel bars, so that a large amount of force can be shared.

In the present disclosure, the lower portion of the rib beam formed of the cast-in-place concrete may be provided with a pocket floor, whereby it is unnecessary to additionally provide a bottom formwork when casting the concrete rib beam.

In another embodiment, the rib beam can also be formed with an i-shaped cross section, whereby the frame of the prefabricated cavity floor can be at least partially located inside the rib beam, i.e. in the recess of the rib beam, whereby the cross-sectional height of the rib beam is increased and a structural system with better mechanical properties is formed.

Fig. 34 and 35 are partial structural views of a building according to various embodiments of the present disclosure, i.e., longitudinal sectional views of rib structures.

According to another aspect of the present disclosure, there is provided a building comprising the fabricated cavity building structure described above.

As shown in fig. 23, 34 and 35, the building further includes side walls or beams 8000, joists 9000 and the like.

Of course, the number of prefabricated cavity floors 1000 of each prefabricated cavity building structure may be other values, for example, the prefabricated cavity building structure shown in the middle of fig. 23 includes two prefabricated cavity floors 1000 and one rib beam 2000, and the rib beam 2000 is located between the two prefabricated cavity floors 1000.

The joists 9000 are located between prefabricated cavity floors of two adjacent fabricated cavity building structures. As shown in fig. 23, a vertically disposed joist 9000 is located between two horizontally disposed fabricated cavity building structures and, correspondingly, a horizontally disposed joist is located between two vertically disposed fabricated cavity building structures.

The connection between the fabricated cavity building structure and the side walls or beams 8000 and joists 9000 will be described with reference to the accompanying drawings.

A fabricated cavity building structure is provided on the wall portion 8001, and at least a portion of the fabricated cavity building structure is located to be erected on the wall portion 8001. For example, in actual use, the frame 1001 of the fabricated cavity building structure is erected on the wall portion 8001, so that the position of the frame 1001 can be preliminarily fixed.

On the other hand, the wall 8001 may be provided with a lug structure, and in this case, the frame 1001 of the assembled cavity building structure may be provided on the lug structure.

When the prefabricated cavity floor 1000 of the fabricated cavity building structure is set, the connector 1003 of the prefabricated cavity floor 1000 is set above the wall 8001, and when the pouring portion 8002 is obtained by concrete pouring, the connector 1003 of the prefabricated cavity floor 1000 is located inside the pouring portion 8002.

Moreover, the connection portion 4002 of the cover plate 4000 is also located in the pouring portion 8002, and both the connection member 1003 of the prefabricated cavity floor 1000 and the connection portion 4002 of the cover plate 4000 can be anchored to the pouring portion 8002, and also the pouring portion 8002 and the prefabricated cavity floor 1000 and the cover plate 4000 can have higher connection strength and anchoring reliability.

That is, when the building includes side walls, the casting 8002 is formed as a wall cast in place with the laminated layers.

When the building includes a boundary beam 8000, referring again to fig. 28-30, the component indicated by reference numeral 8001 may be a lower prefabricated boundary beam, and the component indicated by 8002 is a boundary beam cast integrally with the laminated layer; in another instance, the component indicated by reference numeral 8001 may be a support column, masonry, or blank structure, and the component indicated by 8002 is a side rail cast integrally with the laminate layer.

As shown in fig. 31 and 33, at least a portion of the connector 1003 of the prefabricated cavity floor 1000 is located inside the joist 9000.

Thus, the connector 1003 of the prefabricated cavity floor 1000 can be connected or anchored to the joist 9000. Of course, the connection members 1003 may be connected or anchored to each other at the location of the joists 9000, for example, the connection members 1003 of the prefabricated cavity floor 1000 of the adjacent prefabricated cavity building structure may be directly connected or anchored, or may be connected or anchored by a frame member provided inside the joists 9000, wherein the frame member may be a reinforcing bar provided along the length direction of the joists 9000 (or in a direction perpendicular or substantially perpendicular to the connection members 1003), the end portions of the connection members 1003 may be formed with hooks, and the hooks may be hooked on the frame member, thereby enabling the connection members 1003 of the adjacent prefabricated cavity floor 1000 to be connected or anchored to each other, and at the same time, the frame member may be formed as a frame of the joists 9000, and enabling the rib beams to have higher strength and bearing capacity.

In a specific embodiment, the skeleton member may be a plurality of reinforcing bars, which may be arranged in a plurality of rows in a vertical direction, and each row of reinforcing bars may include a plurality of reinforcing bars. In a preferred embodiment, each row of rebar can also be positioned in correspondence with the connector 1003 of the prefabricated cavity floor 1000, thereby facilitating connection of the connector 1003 to the skeletal member. More preferably, when the reinforcement bars of a certain row of the skeletal member include a plurality of reinforcement bars, the connector 1003 is connected to the reinforcement bar farthest therefrom, so that the connector 1003 can have the maximum length within the joist 9000, thereby improving the reliability of anchoring and also improving the connection strength between the prefabricated cavity floor 1000 and the joist 9000.

Similarly, in the present disclosure, the connection portion 4002 of the cover plate 4000 can be anchored to the joist 9000. Of course, the connection parts 4002 may be connected or anchored to each other at the positions of the joists 9000, for example, the connection parts 4002 of the adjacent cover plates 4000 may be directly connected or anchored, or may be connected by a frame member provided inside the joists 9000, wherein the frame member may be a reinforcing bar provided in the length direction of the joists 9000 (or in a direction perpendicular or substantially perpendicular to the connection parts 4002), the end parts of the connection parts 4002 may be formed with hooks, and the hooks may be hooked on the frame member, thereby enabling the connection parts 4002 of the adjacent cover plates 4000 to be connected or anchored to each other, and at the same time, the frame member may be formed as a frame of the joists 9000, and enabling the rib beams to have higher strength and bearing capacity.

In a specific embodiment, the reinforcement bars of the frame member can also correspond to the location of the connection portion 4002 of the cover plate 4000 to facilitate the connection of the connection portion 4002 to the frame member. More preferably, when the reinforcement bar of a certain row of the skeletal member includes a plurality of reinforcement bars, the connection portion 4002 is connected to the reinforcement bar farthest therefrom, so that the connection portion 4002 can have the maximum length within the joist 9000, thereby improving the strength and anchoring reliability of the joist 9000, and also improving the connection strength between the cover plate 4000 and the joist 9000.

The joist 9000 is provided with a lug structure, and supports the fabricated cavity building structure through the lug structure. Moreover, the joists 9000 can be supported by support columns, thereby enabling the building to have a stronger bending resistance.

The bolster 9000 may be integrally cast concrete, may be a laminated reinforced concrete beam, or may be integrally prefabricated.

In the disclosure, when the area of the space structure is 0.8-2.5 square meters, namely when the space structure is formed into a square shape and the side length of the space structure is about 0.9-1.5m, the prefabricated cavity floor is formed into a multi-ribbed prefabricated cavity floor; correspondingly, when the area of the empty lattice structure is 56-64 square meters, namely when the empty lattice structure is formed into a square, the side length of the empty lattice structure is 7-8m, the prefabricated cavity floor is formed into a primary beam floor and a secondary beam floor. I.e., the rib structure 1002 has a larger cross-sectional area, which may be referred to as a beam.

Although not shown in the present disclosure, the cover plate 4000 and the prefabricated cavity floor 1000 of the present disclosure may be integrally formed, for example, integrally prefabricated by means of concrete pouring. The cover 4000 may also be referred to as an upper sealing plate, which may be formed as a single body and closes the upper end of the space structure; preferably, the cover 4000 may close the upper end of the space structure, or close the upper end of the frame 110.

In this embodiment, the rib 2000 may be provided only between two adjacent prefabricated cavity floors 1000.

The prefabricated cavity floor is mainly subjected to self-weight and live load, and under the action of gravity, compressive stress is generated at the upper part and tensile stress is generated at the lower part in the prefabricated cavity floor, so that the two components form resisting moment. Concrete is a brittle material which is suitable for compression resistance but not for tension, so that the lower tensile force needs to be borne by the steel bars, and the upper compressive force is borne by the concrete, so that the lower concrete becomes a load (encumbrance), namely an excessive dead weight load.

When the assembled cavity building structure disclosed by the invention is used, not only much concrete and dead weight are saved through the cavity, but also a T-shaped section just accords with the mechanical characteristic through the arrangement of the T-shaped rib beam, and a large amount of superfluous concrete at the lower part is saved.

When the assembled cavity building structure disclosed by the invention has the superposition layer, the T-shaped rib beam and the superposition layer work cooperatively, a T-shaped rib beam and a prefabricated cavity building cover provided with the superposition layer are combined in the same width, the load is a fixed value, the local bending resistance of the T-shaped rib beam with the same width and the prefabricated cavity building cover provided with the superposition layer is basically the same, so that the two bending resistance structures are arranged in the same width, and the bearing capacity is greatly increased when the T-shaped rib beam and the prefabricated cavity building cover provided with the superposition layer are combined to form the whole cooperative work.

Considering the overall effect of the lamination layer: the prefabricated components can deform in advance because of replacing templates, the rigidity and the bearing capacity of the cast-in-situ full-size equivalent structure cannot be achieved after the laminated layers are poured, the cast-in-situ structure is not broken, that is, the prefabricated cavity floor provided with the laminated layers is broken in bearing capacity, the bearing capacity of the post-cast T-shaped rib beam is not broken, and the overall bearing capacity is enhanced.

By combining the analysis of the situations, the assembled cavity building structure disclosed by the invention is a cooperative structure, the T-shaped rib beam is a main structural member and plays an important role, the mechanical contribution of the T-shaped rib beam is very large, and the T-shaped rib beam can also enable the steel bars of the prefabricated cavity floors at two sides to be connected or anchored and run through at the joint to form a more superior bidirectional stress structure.
