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.

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.

As shown in fig. 1 and 2, the prefabricated sealing rib panel 1000 includes a frame 1001, a rib structure 1002, and a capping panel 1006.

In number, the transverse rib structure may be provided in one or more, and correspondingly, the vertical rib structure may be provided in one or more. Accordingly, these vertical rib structures may be arranged in parallel, and accordingly, may be arranged in non-parallel. The transverse rib structure can intersect at least a portion of the vertical rib structure such that the interior space of the frame 1001 is divided into a plurality of space structures by the transverse rib structure and the vertical rib structure. In a preferred embodiment, the space structures may be the same or different in shape and the areas may be the same or different.

Fig. 3 and 4 show an embodiment in which only one transverse rib structure is present, and fig. 6 and 7 show an embodiment in which two transverse rib structures are present. In the present disclosure, the number of the transverse rib structures is not limited thereto.

The periphery of the prefabricated rib 1000 is not provided with the connector 1003, or as shown in fig. 1 to 8, at least part of the periphery of the prefabricated rib 1000 is provided with the connector 1003. In a specific embodiment, the connector 1003 may be a steel structure, such as rebar, or the like. The connection member 1003 is located inside the frame 1001 and/or the rib structure 1002, for example, may be connected to a stress bar or a construction bar of the frame 1001 and/or the rib structure 1002, and the other end extends outside the frame 1001 to form a free end.

The connectors 1003 may be arranged in at least one row along the height of the prefabricated rib 1000, i.e. the connectors in a row may lie on or near the same plane, e.g. on the same horizontal plane; in a preferred embodiment, the connectors 1003 may be arranged in two rows, with one row of connectors 1003 at or near the lower end of the housing 1001 and the other row of connectors 1003 at or near the upper end of the housing 1001.

Of course, the connector 1003 of the present disclosure may be provided in two or more in the height direction of the prefabricated rib 1000. For example, a row of connectors 1003 may be provided at a central location of the frame 1001.

At least one concave structure 1004 is formed on at least a part of the outer peripheral surface of the frame 1001 of the prefabricated rib 1000. In the present disclosure, the recess structure 1004 may be formed as a ring-shaped structure, a discontinuous structure, i.e., an annular recess structure, or a discontinuous recess. 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.

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.

Fig. 9 is a schematic structural view of a building according to one embodiment of the present disclosure.

As shown in fig. 9, the assembled rib plate building structure includes the prefabricated rib plate 1000, and the rib beam 2000, the laminated layer 3000 and the like described below.

Of course, if the strength of the connection of the prefabricated dense rib 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 region between two adjacent ones of the pre-formed dense ribs 1000. In the process of manufacturing the fabricated dense rib plate building structure, adjacent prefabricated dense rib plates 1000 are spaced apart by a predetermined distance or a predetermined width, so that a predetermined space is formed between the prefabricated dense rib plates 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 body 1001 of the prefabricated rib 1000, so that the fabricated rib plate building structure has better mechanical properties.

On the other hand, since the prefabricated dense rib 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 dense rib 1000 and the rib beam 2000.

In the present disclosure, when the connectors 1003 are provided at the periphery of the prefabricated rib 1000, at least a portion of the connectors 1003 are located inside the rib 2000, and thus, the connectors 1003 of the prefabricated rib 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 close rib plate structure system has the advantages of being stressed bidirectionally and having larger bearing capacity.

For example, the connection parts 1003 of the adjacent prefabricated rib plates 1000 can be directly connected or connected by a reinforcing member 2001 provided inside the rib beam 2000, wherein the reinforcing member 2001 may be a reinforcing bar provided along the length direction of the rib beam 2000, the end parts of the connection parts 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 connection parts 1003 of the adjacent prefabricated rib plates 1000 can be more closely connected to each other, and at the same time, the reinforcing member 2001 can also be formed as a skeleton of the rib beam 2000, and the rib beam has a strong bending moment resistance, a larger bearing capacity, and a higher strength, whereby the prefabricated rib plate structure system having the rib beam as a whole can also have a larger bearing capacity and a higher strength.

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 dense rib plate structure system, meanwhile, the rib structures between the prefabricated dense rib plates 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 dense rib plate structure system, wherein the laminated layer 3000 can also be called a flange.

In other words, compared with the case that there is no reinforcing member between the prefabricated dense rib plates or between the prefabricated dense rib plates and the prefabricated plates, that is, the case that the space between the prefabricated plates has no bearing capacity, 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 dense rib plates, 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 2000, thereby improving the reliability of the anchoring connection and also improving the connection strength between the prefabricated dense rib 1000 and the rib 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.

In the present disclosure, the rib beam 2000 may not have a reinforcing member 2001 inside, and may not have a beam function, but only serve to connect two adjacent prefabricated rib plates 1000, and accordingly, the rib beam 2000 may also transmit force to improve the bearing capacity of the fabricated rib plate building structure.

When the rib 2000 is formed, the lower surface of the rib 2000 is flush with the lower surface of the prefabricated rib 1000. In other embodiments, the lower surface of the rib 2000 may be higher or lower than the lower surface of the pre-fabricated dense rib 1000, so long as the connection strength between the rib 2000 and the pre-fabricated dense rib 1000 is sufficient.

Fig. 10 is a schematic cross-sectional structural view of an assembled close-rib building structure according to one embodiment of the present disclosure.

As shown in fig. 10, a lamination layer 3000 is disposed above the prefabricated rib 1000 of the fabricated rib plate building structure, and the lamination layer 3000 and the rib beam 2000 are integrally formed by cast-in-place concrete. Accordingly, the laminate 3000 and the rib 2000 are formed as a unitary force-bearing structure when concrete is poured.

In the present disclosure, the fabricated rib plate building structure of the present disclosure can be formed into an integral structure by the lamination layer 3000, and can be integrally stressed together.

Fig. 11 and 12 are schematic cross-sectional structural views of assembled close-rib building structures according to various embodiments of the present disclosure.

As shown in fig. 10 to 12, extension bars 3001 are further provided at positions above the top cover 1006, and for example, the extension bars 3001 may be provided in plurality, and in this case, the extension bars 3001 may be provided in the direction of the frame 1001 and/or the rib structure 1002, so that the strength of the laminated layer 3000 may be improved.

The fabricated rib panel 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 dense rib plate building structure disclosed by the utility model, the construction speed of buildings such as an underground garage of a building can be greatly improved, and the dead weight of the assembled dense rib plate building structure is lower, so that the assembled dense rib plate 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.

When the assembled dense rib building structure disclosed by the utility model is used, the rib beam 2000 can be supported by the support columns, the support beams and other components, so that the mechanical property of the assembled dense rib building structure is further improved.

As shown in fig. 11 and 12, the assembled dense rib building structure includes a laminate 3000, where the upper surface of the rib beam 2000 is flush with the upper surface of the prefabricated dense rib 1000, and further, as shown in fig. 11, the lower surface of the rib beam 2000 is flush or substantially flush with the lower surface of the prefabricated dense rib 1000.

And, as shown in fig. 12, the lower surface of the rib beam 2000 extends beyond the lower surface of the prefabricated rib 1000, thereby providing the rib beam 2000 with higher strength and correspondingly providing the fabricated rib building structure with higher strength.

The assembled rib plate building structure solves the technical problems in the background art through the prefabricated rib plate structure.

Under the condition that the material consumption is equal and the area is equal, compared with a solid plate, the prefabricated dense rib plate assembled by the prefabricated dense rib lattice can greatly increase the section moment of inertia, further greatly improve the bending resistance, realize larger span or stronger bearing capacity, realize industrial production and accelerate the construction speed, and the prefabricated dense rib lattice saves a large amount of concrete in a cavity and greatly lightens the structural dead weight, so that the prefabricated dense rib lattice is assembled into a building roof structure, the effective bearing capacity can be greatly improved, the building dead weight can be greatly lightened, the building cost can be greatly reduced, and the prefabricated dense rib plate assembled by the prefabricated dense rib lattice can be produced in a large scale in an industrialized manner, can be assembled quickly at a construction site and greatly saves the construction period.

The T-shaped rib beam is arranged for greatly improving the bearing capacity, the spacing of the multi-rib floor slab is utilized, the stress, the structure and the bending steel bars are arranged in a targeted mode, the rib beam and the superposed layer are cast into a whole, the T-shaped section with large moment of inertia and excellent mechanical properties is formed, the bearing capacity of the whole floor slab is greatly improved, and the T-shaped section and the prefabricated multi-rib floor slab resist bending moment together.

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 framework of the prefabricated close-fitting rib can be at least partially located inside the rib beam, i.e. in the recess of the rib beam, thereby increasing the cross-sectional height of the rib beam and creating a structural system with superior mechanical properties.

Fig. 19 and 20 are partial structural schematic views of a building, i.e., longitudinal sectional views of a rib beam, according to various embodiments of the present disclosure.

According to another aspect of the present disclosure, there is provided a building comprising the above-described fabricated close-coupled ribbed panel building structure.

As shown in fig. 9, 19 and 20, the building further includes side walls or beams 8000, joists 9000 and the like.

That is, in the building, the outer contour may be a side wall or a side sill. Specifically, when the building is an underground building, the outer contour is a side wall; when the building is an above-ground building, the outline thereof is a side wall or a side beam.

Wherein at least a portion of the side wall or side rail 8000 is used to form an outer boundary of the building, wherein the side wall or side rail 8000 is connected to a prefabricated close rib of the fabricated close rib building structure.

Moreover, the joist 9000 is located in an area surrounded by the side wall or side beam 8000, and an end portion of the joist 9000 is disposed on the side wall or side beam 8000, and the joist 9000 is connected to a prefabricated rib plate of the fabricated rib plate building structure.

For example, referring to the upper left corner of fig. 9, the joists 9000 thereof may be laterally disposed and formed as lateral joists, and the joists 9000 may be longitudinally disposed and formed as longitudinal joists, at which time the lateral and longitudinal joists enclose to form a filling space.

The assembled close-packed ribbed panel building structure is capable of at least partially enclosing the filled space, and in a preferred embodiment, as shown in fig. 9, the assembled close-packed ribbed panel building structure of the filled space in the upper left corner includes three pre-fabricated close-packed ribbed panels 1000 and two ribbed beams 2000, the three pre-fabricated close-packed ribbed panels 1000 being arranged in juxtaposition and one ribbed beam being arranged between two adjacent pre-fabricated close-packed ribbed panels 1000.

Of course, the number of the prefabricated rib plates 1000 of each assembled rib plate building structure may be other values, for example, the assembled rib plate building structure shown in the middle of fig. 9 includes two prefabricated rib plates 1000 and one rib beam 2000, and the rib beam 2000 is located between the two prefabricated rib plates 1000.

The bolster 9000 is located between two adjacent prefabricated close rib panels of an assembled close rib panel building structure. As shown in fig. 9, the vertically disposed joist 9000 is located between two horizontally disposed fabricated rib plate building structures and, correspondingly, the horizontally disposed joist is located between two vertically disposed fabricated rib plate building structures.

The connection between the assembled close-coupled ribbed panel building structure and the side walls or beams 8000 and joists 9000 will be described below with reference to the accompanying figures.

Fig. 13 to 15 are partial structural schematic views of a building according to various embodiments of the present disclosure.

As shown in fig. 13 to 15, the side wall 8000 includes a wall portion 8001 and a pouring portion 8002; when constructing the building, the wall portion 8001 is formed by concrete casting, and the height of the wall portion 8001 is limited to a reasonable height, for example, a height of 2 meters to 3 meters or the like. The wall portion 8001 is provided with a fabricated rib plate building structure, and at least a part of the fabricated rib plate building structure is located to be erected on the wall portion 8001. For example, in actual use, the frame 1001 of the fabricated rib 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, a lug structure may be provided on the wall portion 8001, and in this case, the frame 1001 of the assembled rib plate building structure may be set up on the lug structure.

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

In one embodiment, the extension steel bars 3001 of the laminated layer 3000 can also be located in the pouring portion 8002, and the extension steel bars 3001 can be formed into a bending structure, and the bending structure is adapted to the shape of the pouring portion 8002, so that the laminated layer 3000 and the pouring portion 8002 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. 13-15, 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.

Fig. 16 to 18 are partial structural schematic views of a building according to various embodiments of the present disclosure.

As shown in fig. 16 and 18, at least part of the connector 1003 of the prefabricated rib 1000 is located inside the bolster 9000.

That is, the prefabricated rib 1000 may include a first direction and a second direction, for example, the first direction is a length direction of the prefabricated rib 1000, and the second direction is a width direction of the prefabricated rib 1000, where the first direction and the second direction are different when the prefabricated rib 1000 is in other shapes.

When the periphery of the prefabricated dense rib plate 1000 does not comprise the connecting piece 1003, a stress system is formed between beam structures of the building, and the prefabricated dense rib plate 1000 is formed into a filling structure; accordingly, when the connectors 1003 are provided at both ends of the prefabricated rib plate 1000 in the first direction, the prefabricated rib plate 1000 and the bolster 9000 can form an integral unidirectional stress system. On the other hand, when the connectors 1003 are also provided at both ends of the prefabricated dense rib 1000 in the second direction, the connectors 1003 in the second direction can be anchored or connected within the rib 2000, so that the prefabricated dense rib 1000 is formed as a bidirectional force system.

Thus, the connector 1003 of the prefabricated rib 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 position of the joist 9000, for example, the connection members 1003 of the prefabricated rib plates 1000 of the adjacent assembled rib plate building structure may be directly connected or anchored, or may be connected or anchored by a frame member provided inside the joist 9000, wherein the frame member may be a reinforcing bar provided along the length direction of the joist 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 rib plates 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 joist 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 reinforcing bars may also be positioned in correspondence with the connectors 1003 of the prefabricated rib 1000, thereby facilitating the connection of the connectors 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 rib 1000 and the joist 9000.

The joist 9000 is provided with a lug structure, and supports the assembled rib plate 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 rib plate is formed into a rib plate; 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 dense rib plate 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.

In this embodiment, the rib 2000 may be provided only between two adjacent ones of the pre-formed dense ribs 1000.

The prefabricated dense rib plate is mainly subjected to self weight and live load, and under the action of gravity, the upper part in the prefabricated dense rib plate generates compressive stress and the lower part generates tensile stress, so that the compressive stress and the tensile stress 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 dense rib plate building structure is used, the 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 dense rib plate building structure disclosed by the utility model has the superposition layer, the T-shaped rib beam and the superposition layer work cooperatively, a T-shaped rib beam and a prefabricated dense rib plate combination provided with the superposition layer are arranged in the same width, the load is a fixed value, the T-shaped rib beam with the same width and the prefabricated dense rib plate with the superposition layer have the same bending resistance in local areas, 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 dense rib plate combination provided with the superposition layer are combined into the whole cooperative work.

Considering the overall effect of the lamination layer: the prefabricated component can deform in advance because of replacing the template, the rigidity and the bearing capacity of the cast-in-situ full-size equivalent structure cannot be achieved after the laminated layer is poured, the cast-in-situ structure is not broken, that is, the prefabricated dense rib plate provided with the laminated layer is broken in bearing capacity, the bearing capacity of the post-poured T-shaped rib beam or rib beam is not broken, and the integral bearing capacity is enhanced.

By combining the analysis of the situations, the assembled dense rib plate building structure disclosed by the utility model is a cooperative structure, the T-shaped rib beam or rib beam is also a main structural member and plays an important role, the mechanical contribution of the T-shaped rib beam or rib beam is very large, and the reinforced bars of the prefabricated dense rib plates or rib structures on two sides can be connected or anchored and run through at the position to form a more superior bidirectional stress structure.
