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," above, "" upper, "" above, "" higher, "and" side (e.g., as in "sidewall") to describe one component's relationship to another (other) component as shown 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" may 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.
According to one embodiment of the present disclosure, a building structure employing hollow panels is provided. Fig. 1 illustrates a schematic view of a building structure employing hollow slabs according to one embodiment of the present disclosure, and fig. 2 illustrates a schematic sectional structure of fig. 1. As shown in fig. 1 and 2, the building structure using the hollow slab of the present disclosure may include a top plate 710, a bottom plate 720, at least one intermediate plate 730, a surrounding wall 740, and the like. The building structure 700 using the hollow slab may be an above-ground building, an underground building, a motor vehicle garage or a non-motor vehicle garage, or may be other buildings of various types. The top plate 710 is formed as a top of the building structure 700 using the hollow slab, and the top plate 710 may be formed using a beam-free floor or a beam-equipped floor, wherein the beam-equipped floor may include a beam structure disposed in a first direction and a beam structure disposed in a second direction, wherein the first direction and the second direction are not parallel, i.e., the first direction and the second direction are formed at an angle, e.g., the first direction and the second direction are perpendicular. The floor slab can adopt a superposed T-rib hollow structure. When the building structure 700 using the hollow slab is formed as an underground parking garage, the upper side of the roof 710 may be provided with an overburden layer; when the building structure 700 using the hollow slab is formed as an above-ground parking garage, the roof 710 is formed as the uppermost portion of the building structure 700 using the hollow slab. Preferably, the top plate 710 may be provided with a lighting vent hole, etc., which may be formed above the hollow space 750, for example, on a square or obliquely above the hollow space 750. The base plate 720 is formed as the bottom of the building structure 700 using hollow plates. The floor 720 includes at least one bottom travel lane for vehicle traffic, and a bottom parking space disposed on at least one side of the bottom travel lane such that a vehicle can be parked in the bottom parking space. The floor 720 may be formed by concrete casting, and the floor parking spaces, the floor driving lanes, etc. may be formed by drawing on the floor 720 according to actual design construction requirements.
The middle plate 730 is disposed between the top plate 710 and the bottom plate 720 at a predetermined distance, which may be determined according to the number of the middle plates 730, for example, when the middle plate 730 is one layer, the building structure 700 using the hollow plate having two parking layers is formed, and the distance between the top plate 710 and the bottom plate 720 may be 5-6m; when the middle plate 730 is formed in two floors, the building structure 700 using the hollow plate having three parking floors is formed, and at this time, the distance between the two middle plates 730 may be set to about 2-3m, and accordingly, the distance between the top plate 710 and the bottom plate 720 may be set to 7-9m. Of course, the middle plates 730 may be provided in various numbers of three, four, five, etc., and the distance between the middle plates 730 and the top plate 710 or the bottom plate 720 may be selected according to actual design construction requirements. When the number of the intermediate plates 730 is two or more, the intermediate plates 730 may be disposed in a vertical direction; the intermediate plates 730 may be arranged in parallel, for example, the intermediate plates 730 are arranged in a horizontal plane. The middle plate 730 may be disposed parallel to the top plate 710 and the bottom plate 720, and of course, the middle plate 730, the top plate 710 and the bottom plate 720 may be disposed non-parallel to each other, and may be selectively disposed according to actual design construction requirements by those skilled in the art. Each intermediate panel 730 includes at least one intermediate traveling lane for vehicle traffic, and intermediate parking spaces provided on at least one side of the intermediate traveling lane, in which case vehicles may also be parked in the intermediate parking spaces. When the number of the intermediate plates 730 is one, the intermediate plates 730 communicate with the bottom plate 720 through the connection lanes, and the vehicle moves from the bottom plate 720 to the intermediate plates 730 and/or from the intermediate plates 730 to the bottom plate 720 through the connection lanes. Alternatively, the intermediate plate 730 communicates with the floor 720 via a vehicle conveyor (not shown) by which the vehicle moves from the floor 720 to the intermediate plate 730 and/or from the intermediate plate 730 to the floor 720. When the number of the intermediate plates 730 is two or more, the adjacent intermediate plates 730 are connected by connecting lanes such that the vehicle moves from the upper intermediate plate 730 to the lower intermediate plate 730 and/or from the lower intermediate plate 730 to the upper intermediate plate 730 through the connecting lanes, and the lowermost intermediate plate 730 communicates with the bottom plate 720 through the connecting lanes such that the vehicle moves from the lowermost intermediate plate 730 to the bottom plate 720 and/or from the bottom plate 720 to the lowermost intermediate plate 730 through the connecting lanes.
The enclosing wall 740 is disposed between the top plate 710 and the bottom plate 720 and at least partially encloses the middle plate 730, that is, when the enclosing wall 740 is formed in a ring-shaped structure, the enclosing wall 740 may enclose a closed space together with the top plate 710 and the bottom plate 720, or when the enclosing wall 740 has an opening through which a vehicle may enter the building structure 700 using the hollow plate from the outside, the enclosing wall 740 may enclose a space together with the top plate 710 and the bottom plate 720. When the enclosure wall 740 is actually used as a supporting and bearing wall, it also has various characteristics of a bearing wall, for example, when the enclosure wall is disposed at the beam and/or plate structure lower end of the building structure 700 using the hollow slab and supports and/or bears the beam and/or plate structure, so that the structural performance of the building structure 700 using the hollow slab is more stable, the enclosure wall 740 is actually a bearing wall, but if the disposed enclosure wall does not serve to support and bear the beam and/or plate structure of the building structure 700 using the hollow slab, but only serves to seal or block a certain area, the enclosure wall is not a bearing wall, but only serves as an enclosure wall, regardless of whether the enclosure wall is disposed at the beam and/or plate structure lower part of the building structure 700 using the hollow slab and contacts the beam and/or plate structure.
At least one of the top plate 710, the bottom plate 720, or the middle plate 730 of the building structure 700 using the hollow plate is constructed of a laminated T-ribbed hollow structure. Preferably, at least a partial region of at least one of the top plate 710, the bottom plate 720, or the middle plate 730 of the building structure 700 using the hollow plate is constructed of a laminated T-ribbed hollow structure. Preferably, the overlapping T-rib hollow structure may be used in floor, roof, floor, roof or roof structures in a variety of buildings, including buildings such as above-ground, below-ground, motorized garage or non-motorized garage.
The building structure comprising a composite T-ribbed hollow structure of prefabricated hollow panels, T-ribbed structures and hybrid stacks is further described below.

The protruding reinforcing bars of the side beam 520 may be used as reinforcing bar structures of the connection structure, and reinforcing bars of the connection structure may be separately provided. The connection structure is similar to a T-rib structure and may also be considered a T-rib structure.

Fig. 23 shows an embodiment of the combination of the hollow core slab 100 and the bolster 400 shown in fig. 18 (a section in the B-B direction shown in fig. 5)). Wherein the protruding rebars 120 of the hollow slab as shown in fig. 23 may be anchored/connected to the joists 400/supporting walls (cast in place concrete). The manner in which the hollow core slab 100 is combined with the supporting beams 410 is described below with reference to fig. 23, and the hollow core slab 100 is combined with such a supporting wall when the upper portion of the supporting wall is a beam structure. In this embodiment, the hollow core slab is provided only at one side of the bolster 410. The hollow precast slab is adjacent to the joist 410 and may be disposed over a portion of the joist 410. The bolster 410 may be a prefabricated composite beam or a cast-in-place beam. After the placement of the hollow precast slab relative to the bolster 410 is completed, concrete may be cast in place to form the connection structure and the mix layer. The protruding reinforcing bars of the joist 410 may be used as reinforcing bars of the connection structure, or may be separately provided. The connection structure is similar to a T-rib structure. As an example, the connection structure includes a longitudinal rebar extension 411 and/or a transverse rebar extension 412, the details of which may be referred to in the foregoing description, wherein the longitudinal rebar extension 411 extends longitudinally with respect to a longitudinal section of the joining location, and the longitudinal rebar extension 411 includes a second rebar diagonal and/or perpendicular with respect to the longitudinal section of the joining location and a tie for hooping the second rebar and/or for achieving a drawknot, the transverse rebar extension 412 extends transversely with respect to the longitudinal section of the joining location, and the transverse rebar extension 412 may be a separately provided rebar structure and/or a rebar structure that is a mixed layer. The upper portion of the longitudinal rebar extension 411 may or may not be connected to the transverse rebar extension 412. In addition, a transverse reinforcement extension structure is not required. For further details reference is made to the content of the previous T-rib structure. The protruding rebar structures of the joists 410 may be used as the rebar structures of the connection structure in fig. 23, for example, the protruding rebar structures may be prefabricated or reserved when prefabricating the joists 410, or the protruding rebar structures may be reserved when casting the joists 410 in situ. The manner of coupling with the bolster 420 is described with reference to fig. 23. In this embodiment, the hollow core slab is provided only at both sides of the bolster 420. The hollow precast slab is adjacent to the joist 420 and may be disposed over a portion of the joist 420. The bolster 420 may be a prefabricated composite beam or a cast-in-place beam. After the placement of the hollow precast slabs relative to the bolster 420 is completed, concrete may be cast in place to form the connection structure and the mix layer. The protruding reinforcing bars of the bolster 420 may be used as reinforcing bars of the connection structure, or may be separately provided. The connection structure is similar to a T-rib structure. As an example, the connection structure includes a longitudinal rebar extension 421 and/or a transverse rebar extension 422, the details of which may be referred to in the foregoing description. The upper portion of the longitudinal rebar extension 421 may be disconnected from the transverse rebar extension 422. In addition, a transverse reinforcement extension structure is not required. For further details reference is made to the content of the previous T-rib structure. The protruding rebar structures of the joists 420 may be used as the rebar structures of the connection structure in fig. 23, for example, the protruding rebar structures may be prefabricated or reserved when prefabricating the joists 420, or the protruding rebar structures may be reserved when casting the joists 420 in situ. Meanwhile, according to the actual design construction requirement, the overlapped T-rib hollow structure can be directly arranged on the bearing wall, so that the bearing wall plays a further supporting role on the overlapped T-rib hollow structure, the load of a floor slab is increased, a part of the overlapped T-rib hollow structure can be arranged on the bearing wall, the load of the floor slab can be increased, for example, as for the formed overlapped T-rib hollow structure, the position of the bearing wall can be the same as the arrangement direction of the corresponding bearing beam, and according to the actual design construction requirement, the thickness of the bearing wall can exceed the thickness of the corresponding bearing beam, therefore, in order to further increase the load of the floor slab, the prefabricated hollow slab of the overlapped T-rib hollow structure can be arranged on a part of the bearing wall. Of course, when the combination of the hollow structure of the overlapping T-rib and the column and beam structure meets the load requirement of the floor slab, the hollow structure of the overlapping T-rib may not directly connect with the supporting wall, for example, the hollow structure of the overlapping T-rib may be adjacent to the supporting wall but not connected. Of course, according to actual design construction needs, when the hollow slab stretching out reinforcing steel bar is not arranged, and the overlapping T-rib hollow structure can meet the floor load requirement through combination with the column, the beam and/or the bearing wall, the hollow slab stretching out reinforcing steel bar can be not arranged, and at the moment, the overlapping T-rib hollow structure can be connected to the bearing beam/bearing wall through cast-in-place concrete.
As shown in fig. 23, blocking heads 150 may be provided at both ends of the hollow structure of the precast hollow slab to prevent concrete from entering the hollow structure when concrete is cast in place.
Fig. 24 shows another embodiment of the combination of the hollow core slab 100 and the bolster 400 shown in fig. 18 (a section in the B-B direction shown in fig. 5). The embodiment of fig. 24 differs from the embodiment of fig. 23 in that a lug structure 430 may be provided on the joist to support the hollow slab. In addition, a lug structure may be provided for the side sill 500. As an example, other similar means than a lug structure may be employed, such as increasing the width of the upper end of the beam, etc.
Fig. 25 shows an example of the combination of a T-shaped rib structure and a joist 400 (a section in the direction B-B shown in fig. 5), which is the same as the combination of a bearing wall when the upper part of the bearing wall is used as a beam structure. In the T-ribbed structure, an anchoring bar 350 may be provided, which may be part of the first bar mentioned before, or may be a bar different from the first bar, wherein the anchoring bar 350 may extend to the joists 410 and 420. Anchoring/connecting of the anchor bars 350 at the beam is achieved by cast-in-place concrete, thereby integrating the hollow precast slab 100 with the bolster 400. The cross-sectional view of the rebar structure in the T-ribbed structure is better shown in fig. 25, as shown in fig. 25, and as an example, the rebar structure in the T-ribbed structure may include a first rebar 360 and a stirrup 370, wherein the first rebar 360 may extend in a left-right direction and the stirrup 370 hoops around the first rebar 360, as shown in fig. 25.
The terms "rebar," "rebar structure," "rebar extension," and the like in this disclosure may each be a two-dimensional rebar structure, such as a reinforcement bar, a rebar mesh, or a three-dimensional rebar structure in the form of a rebar cage, and the like. In addition, the form of a prefabricated composite beam or cast-in-situ beam is described above, but the prefabricated composite beam or cast-in-situ beam may be replaced with a prefabricated composite wall or cast-in-situ wall. Further, in the present disclosure, the precast hollow slab may be a precast reinforced concrete prestressed hollow slab or a precast reinforced concrete non-prestressed hollow slab.
In general, the hollow slab is mainly subjected to self-weight and live load, and under the action of gravity, the upper part in the hollow slab generates compressive stress and the lower part generates tensile stress, so that the two forms 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, the upper compressive force is borne by the concrete, and the lower concrete becomes a load (encumbrance)), namely an excessive dead weight load. By additionally arranging the T-shaped rib-shaped structure, the T section just accords with the mechanical characteristic, and a large amount of superfluous concrete at the lower part is saved. In the present disclosure, the overlapping T-rib hollow structure is of the type of structure in which a T-rib structure cooperates with a hybrid laminated hollow slab. When the influence of the dead weight of the structure is not considered: the T-shaped rib structure and the mixed laminated hollow slab are arranged in the same width, the load is a fixed value, the T-shaped rib structure and the mixed laminated hollow slab with the same width have basically the same bending resistance, so to speak, the two bending resistant structures are arranged in the same width, and the T-shaped rib structure and the mixed laminated hollow slab are combined into a whole to bear half of internal force when in cooperative work, and if the T-shaped rib structure is not arranged, the stress of the mixed laminated hollow slab with the same width is almost doubled, and the mixed laminated hollow slab needs to bear independently. Considering the influence of the dead weight of the structure: the T-rib structure reduces its own weight by about 50% compared to the hybrid laminated hollow slab, i.e. the effective load carrying capacity of the T-rib structure is much greater than that of the laminated hollow slab with equal width, which means that the mechanical contribution of the T-rib structure in the combined structure takes an absolute dominant role. Consider the overlapping effect: 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 mixed layer is poured, the cast-in-situ structure is not broken, that is, the hollow slab of the mixed layer has the bearing capacity broken, and the bearing capacity of the T-shaped rib-shaped structure is not broken. By combining the analysis of the above conditions, the superposed T-rib hollow structure is a cooperative structure, the T-rib structure is a main component and plays a leading role, and the mechanical contribution is the largest. The hollow slab or the mixed layer hollow slab plays a secondary role and has smaller mechanical contribution. Without the presence of the T-rib structure, the effective load bearing capacity of the neat hybrid laminate hollow slab will drop substantially, typically by about 30 to 75%, and further, its useful span and economy will also drop substantially.
The building structure adopting the hollow plate can obviously improve the overall stress condition of the building due to the adoption of the superposed T rib hollow structure, the top plate, the middle plate and the bottom plate of the building structure adopting the hollow plate are more attractive on the basis of ensuring the mechanical requirement, the arrangement of pipelines is also more facilitated, more building space is saved, and the overall height of the building structure adopting the hollow plate can be effectively reduced, so that the manufacturing cost can be greatly reduced.
