Technical field

Background technique

A building that is assembled from prefabricated components on a construction site is called a prefabricated building. Although prefabricated buildings have increased the construction speed of buildings, due to their higher cost compared to traditional buildings, there is a certain difficulty in promotion.

In terms of quantity, the number of transverse rib structures may be one or more, and correspondingly, the number of vertical rib structures may be one or more. Correspondingly, these vertical rib structures may be arranged in parallel, and correspondingly, they may not be arranged in parallel. The transverse rib structure can intersect at least part of the vertical rib structure, so that the internal 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 shapes of these space structures can be the same or different, and the areas can also be the same or different.

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

No connectors 1003 are provided around the periphery of the prefabricated dense-rib panel 1000, or as shown in Figures 1 to 8, at least part of the periphery of the prefabricated dense-rib panel 1000 is provided with connectors 1003. In a specific embodiment, the connecting member 1003 may be a steel structure, such as steel bars. The connector 1003 is partially located inside the frame 1001 and/or the rib structure 1002. For example, it can be connected to the stress-bearing steel bars or structural steel bars of the frame 1001 and/or the rib structure 1002. The other end extends out of the frame 1001 and/or the rib structure 1002. The outside of the frame 1001 is formed as a free end.

Along the height direction of the prefabricated dense-ribbed panel 1000, the connectors 1003 can be arranged in at least one row, that is, the connectors in a certain row can be located on the same plane or close to the same plane, for example, located on the same horizontal plane. In a preferred embodiment, the connectors 1003 can be arranged in two rows, where one row of connectors 1003 is located at or near the lower end of the frame 1001, and the other row of connectors 1003 is located at the lower end of the frame 1001. at or near the upper end of the frame 1001.

Of course, more than two connectors 1003 of the present disclosure can also be provided along the height direction of the prefabricated dense rib panel 1000 . For example, a row of connectors 1003 may also be provided in the middle of the frame 1001 .

At least one recessed structure 1004 is formed on at least part of the outer peripheral surface of the frame 1001 of the prefabricated dense-ribbed panel 1000 . In the present disclosure, the recessed structure 1004 may be formed into an annular structure or a discontinuous structure, that is, formed into an annular recessed structure or discontinuous recesses. Moreover, the number of the recessed structures 1004 can be set according to the height of the frame 1001. In a preferred embodiment, the recessed structures 1004 are set to two in the height direction. Correspondingly, these two recesses Structure 1004 is formed with three raised structures.

In a preferred embodiment, the cross-section of the rib structure 1002 may be unequal in width up and down or equal in width up and down. The unequal width up and down means that the upper part of the rib structure 1002 is small and the lower part is large, or the upper part is large. Large, small lower part.

Figure 9 is a schematic structural diagram of a building according to an embodiment of the present disclosure.

As shown in Figure 9, the assembled dense-ribbed building structure includes the above-mentioned prefabricated dense-ribbed panels 1000 and the following rib beams 2000 and laminated layers 3000 and other structures.

Of course, if the connection strength between the prefabricated dense rib plate 1000 and the rib beam 2000 is sufficient, the laminate layer 3000 may not be provided.

The rib beam 2000 is disposed in or near the spacing area between two adjacent prefabricated dense rib panels 1000 . In the process of manufacturing the prefabricated dense-ribbed building structure, adjacent prefabricated dense-ribbed panels 1000 are spaced apart by a predetermined distance, or a predetermined width, so that a predetermined space is formed between the prefabricated dense-ribbed panels 1000. The rib beam 2000 can be formed by pouring concrete in the predetermined space. At this time, the rib beam 2000 can form a mechanical connection with the outer peripheral surface of the frame 1001 of the prefabricated dense-ribbed panel 1000, so that the assembled dense-ribbed panel building structure has better mechanical properties.

On the other hand, since the prefabricated dense-rib board 1000 has a recessed structure 1004, the rib beam 2000 formed by pouring has a convex structure inserted into the recessed structure 1004, so that there is a gap between the prefabricated dense-rib board 1000 and the rib beam 2000. Has better connection strength.

In the present disclosure, when the connector 1003 is provided around the prefabricated dense-ribbed panel 1000, at least part of the connector 1003 is located inside the rib beam 2000. Therefore, the connection of the prefabricated dense-ribbed panel 1000 is The member 1003 can serve as at least part of the stress-bearing or structural reinforcement of the rib beam 2000 . Of course, the connectors 1003 can be connected to each other at the position of the rib beam 2000. For example, the connectors 1003 protruding from the two rib structures 1002 in the longitudinal direction are connected at the rib beam, so that the ribs on both sides of the rib beam The structure is substantially extended and can sustain continuous stress. Correspondingly, the same is true in the length direction of the frame, which makes the overall prefabricated dense-ribbed structural system have a superior structural system with bidirectional stress and greater bearing capacity.

For example, the connectors 1003 of adjacent prefabricated dense-ribbed panels 1000 can be directly connected, or connected through reinforcing members 2001 provided inside the rib beam 2000, wherein the reinforcing member 2001 can be located along the length direction of the rib beam 2000. For the provided steel bars, hooks can be formed at the ends of the connectors 1003, and the hooks can be hooked on the reinforcing member 2001, or mechanically connected to each other, or welded, etc., so that adjacent prefabricated dense ribs The connectors 1003 of the plate 1000 can be more closely connected to each other. At the same time, the reinforcing member 2001 can also be formed as the skeleton of the rib beam 2000, so that the rib beam has strong bending moment resistance and greater resistance. Therefore, the prefabricated dense-ribbed plate structural system with rib beams can also have greater load-bearing capacity and higher strength as a whole.

The rib beam structure or the stronger T-shaped rib beam structure (that is, the rib beam 2000 and the laminated layer 3000 jointly form a T-shaped section with better mechanical properties) can enhance the overall load-bearing capacity of the prefabricated dense-ribbed plate structural system, and at the same time It can also allow the rib structures between the prefabricated dense-ribbed panels to be butted to form a full-length force transmission structure, which can work together with the rib beams in the other direction to form a superior two-way prefabricated dense-ribbed panel structural system, in which the superimposed layer 3000 can also be called For the wing edge.

In other words, compared to the situation where there are no reinforcing members between the prefabricated dense ribs or between them and the prefabricated panels, that is, the intervals between the prefabricated panels have no bearing capacity, a key point of this disclosure is to make the post-cast The rib beams and reinforcing members are integrally poured into an important structure that can bear about half of the load. The T-shaped rib beam is formed with a greater bearing capacity and is integrated with the prefabricated dense ribs, which can jointly bear nearly double the load. .

In a specific embodiment, the reinforcing member 2001 may be a plurality of steel bars, the plurality of steel bars may be arranged in multiple rows in the vertical direction, and each row of steel bars may include multiple steel bars. In a preferred embodiment, each row of steel bars can be connected to the corresponding steel bar of another rib beam in the extension direction or anchored into another rib beam, or anchored in the wall, column or beam at the end, thereby facilitating connection The connection between member 1003 and reinforcing member 2001. More preferably, when a certain row of reinforcement members 2001 includes multiple steel bars, the connector 1003 is connected to the steel bar farthest away from it, so that the connector 1003 can have the maximum anchoring length within the rib beam 2000, In this way, the reliability of the anchoring connection is improved, and the connection strength between the prefabricated dense rib plate 1000 and the rib beam 2000 can also be improved.

In a preferred embodiment, the rib beam 2000 also includes a binding member 2002, which can connect the reinforcing members 2001 to each other and keep the reinforcing member 2001 in a reasonable position before concrete is poured.

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

In this disclosure, the reinforcing member 2001 may not be provided inside the rib beam 2000. In this case, the rib beam does not have the function of a beam, but only serves to connect two adjacent prefabricated dense rib panels 1000. Accordingly, Furthermore, the rib beam 2000 can also transmit force to improve the load-bearing capacity of the prefabricated dense-ribbed building structure.

After the rib beam 2000 is formed, the lower surface of the rib beam 2000 is flush with the lower surface of the prefabricated dense rib panel 1000 . In other embodiments, the lower surface of the rib beam 2000 can also be higher or lower than the lower surface of the prefabricated dense-ribbed panel 1000 , as long as the connection strength between the rib beam 2000 and the prefabricated dense-ribbed panel 1000 is sufficient. That’s it.

Figure 10 is a schematic cross-sectional structural diagram of a prefabricated dense-rib building structure according to an embodiment of the present disclosure.

As shown in FIG. 10 , a laminated layer 3000 is provided above the prefabricated dense-ribbed plate 1000 of the prefabricated dense-ribbed building structure. The laminated layer 3000 and the rib beam 2000 are integrally formed by cast-in-place concrete. Accordingly, when pouring concrete, the laminated layer 3000 and the rib beam 2000 form an integral stress-bearing structure.

In the present disclosure, the prefabricated density-ribbed building structure of the present disclosure can be formed into an integral structure by using the superimposed layer 3000, which can jointly bear stress as a whole.

11 and 12 are schematic cross-sectional structural views of a prefabricated dense-rib building structure according to different embodiments of the present disclosure.

As shown in Figures 10 to 12, extension steel bars 3001 are also provided above the ceiling plate 1006. For example, the extension steel bars 3001 can be provided in multiple numbers. In this case, these extension steel bars 3001 can be provided along the frame. 1001 and/or the direction of the rib structure 1002 is set, thereby improving the strength of the laminate layer 3000.

The assembled density-ribbed building structure of the present disclosure can be used for floor or roof structures of above-ground or underground buildings, or for parking floors or roof structures of motor garages or non-motor garages.

Therefore, through the prefabricated dense-rib building structure of the present disclosure, the construction speed of buildings such as underground garages can be greatly improved, and the self-weight of the prefabricated dense-rib building structure is low, so it can save building materials. At the same time, it can withstand large bending moments, reduce construction costs, and achieve energy conservation and emission reduction.

When the prefabricated dense-rib building structure of the present disclosure is in use, the rib beams 2000 can be supported by support columns, support beams and other components, thereby further improving the mechanical properties of the prefabricated dense-rib building structure.

As shown in Figures 11 and 12, the prefabricated dense-rib building structure includes a superimposed layer 3000. At this time, the upper surface of the rib beam 2000 is flush with the upper surface of the prefabricated dense-rib board 1000. Further, , as shown in Figure 11, the lower surface of the rib beam 2000 is flush or substantially flush with the lower surface of the prefabricated dense rib plate 1000.

Moreover, as shown in Figure 12, the lower surface of the rib beam 2000 extends beyond the lower surface of the prefabricated dense-rib panel 1000, so that the rib beam 2000 has higher strength, and accordingly the assembled dense-rib panel Building structures have greater strength.

The prefabricated dense-rib building structure of the present disclosure solves the technical problems mentioned in the background art through the prefabricated dense-rib lattice structure.

Under the conditions of equal amounts of materials and equal areas, compared with solid plates, the assembly of "prefabricated dense-rib lattice" into prefabricated dense-rib plates can greatly increase the cross-sectional moment of inertia, thereby greatly improving the bending resistance and achieving greater span or stronger bearing capacity, realize factory production, speed up construction, and "precast dense-rib lattice structure" saves a large amount of concrete in the cavity and can greatly reduce the weight of the structure. Therefore, prefabricated dense-rib lattice structure is assembled The building roof structure can greatly increase the effective bearing capacity, significantly reduce the weight of the building, and significantly reduce the construction cost. It can also be industrially produced on a large scale and quickly assembled on the construction site, greatly saving the construction period.

The T-shaped rib beam is set up to greatly increase the bearing capacity. It takes advantage of the distance between the densely ribbed floor slabs to specifically configure the stress-bearing, structural and bending steel bars, so that the rib beam and the superimposed layer are poured into a whole to form a moment of inertia. The large T-shaped section with excellent mechanical properties greatly helps improve the load-bearing capacity of the overall floor and works together with the prefabricated dense-ribbed panels to resist bending moments.

In the present disclosure, the lower part of the rib beam formed by the cast-in-place concrete can be provided with a pocket bottom plate, so that when the concrete rib beam is cast and molded, there is no need to provide an additional bottom formwork.

In another embodiment, the rib beam can also be formed into an I-shaped cross-section, whereby the frame of the prefabricated dense-ribbed panel can be at least partially located inside the rib beam, that is, within the recess of the rib beam, thereby increasing the The cross-section height of the rib beam is increased, and a structural system with superior mechanical properties is formed.

According to another aspect of the present disclosure, a building is provided, which building includes the above-mentioned prefabricated dense-rib building structure.

As shown in Figures 9, 19 and 20, the building also includes components such as side walls or side beams 8000 and supporting beams 9000.

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

Wherein, at least part of the side wall or side beam 8000 is used to form the outer boundary of the building, wherein the side wall or side beam 8000 is connected to the prefabricated dense rib board of the assembled dense rib building structure. .

Moreover, the supporting beam 9000 is located in the area enclosed by the side wall or edge beam 8000, and the end of the supporting beam 9000 is disposed on the side wall or edge beam 8000. The supporting beam 9000 is connected to the prefabricated dense rib board of the prefabricated density rib building structure.

For example, referring to the upper left corner of Figure 9, the supporting beam 9000 can be arranged horizontally and formed into a horizontal supporting beam, and the supporting beam 9000 can be arranged longitudinally and formed into a longitudinal supporting beam. In this case, the horizontal supporting beam 9000 can be arranged longitudinally and formed into a longitudinal supporting beam. Joists and longitudinal support beams enclose to form an infill space.

The prefabricated dense-ribbed building structure can at least partially cover the filling space. In a preferred embodiment, as shown in Figure 9, the prefabricated dense-ribbed building structure filling the space in the upper left corner includes three prefabricated The three prefabricated dense-rib panels 1000 and two rib beams 2000 are arranged side by side, and a rib beam is provided between two adjacent prefabricated dense-rib panels 1000.

Of course, the number of prefabricated dense-ribbed panels 1000 in each prefabricated dense-ribbed building structure can also be other values. For example, the prefabricated dense-ribbed building structure shown in the middle of Figure 9 includes two prefabricated dense-ribbed panels 1000 and a rib beam 2000. At this time, the rib beam 2000 is located between the two prefabricated dense rib panels 1000.

The supporting beam 9000 is located between two adjacent prefabricated dense-ribbed panels of the prefabricated dense-ribbed building structure. As shown in Figure 9, the vertically disposed supporting beam 9000 is located between two transversely disposed prefabricated dense-rib building structures. Correspondingly, the transversely disposed supporting beam is located between the two vertically disposed prefabricated dense-rib building structures. between board building structures.

The connection relationship between the prefabricated density-ribbed building structure and the side wall or side beam 8000 and the supporting beam 9000 will be described below with reference to the accompanying drawings.

13 to 15 are partial structural schematic diagrams of buildings according to different embodiments of the present disclosure.

As shown in Figures 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 first formed by pouring concrete. At this time, the wall portion The height of 8001 is limited to a reasonable height, such as 2 meters to 3 meters. A prefabricated dense-rib building structure is provided on the wall portion 8001, and at least part of the prefabricated dense-rib building structure is located on the wall portion 8001. For example, in actual use, the frame 1001 of the assembled density-ribbed building structure is erected on the wall portion 8001, so that the position of the frame 1001 can be initially fixed.

On the other hand, the wall portion 8001 may also be provided with a torus structure, in which case the frame 1001 of the assembled dense-rib building structure can be set up on the torus structure.

After the prefabricated dense-ribbed panels 1000 of the prefabricated dense-ribbed building structure are installed, the connectors 1003 of the prefabricated dense-ribbed panels 1000 are arranged above the wall portion 8001. When the concrete is poured, the After the part 8002, the connector 1003 of the prefabricated dense rib panel 1000 is located inside the pouring part 8002.

In one embodiment, the extended steel bar 3001 of the laminated layer 3000 can also be located in the pouring part 8002, and the extended steel bar 3001 can be formed into a bent structure, and the bent structure is consistent with the pouring part 8002. The shapes are adapted to each other, so that the superimposed layer 3000 and the pouring part 8002 have higher connection strength and anchoring reliability.

That is, when the building includes side walls, the pouring portion 8002 is formed as a wall cast in place together with the laminate layer.

When the building includes edge beams 8000, refer again to Figures 13 to 15. The component indicated by reference numeral 8001 may be a lower prefabricated edge beam, and the component indicated by reference numeral 8002 may be an edge beam cast in place integrally with the laminate layer. ; In another case, the component indicated by reference numeral 8001 may be a support column, masonry or space structure, and the component indicated by 8002 is an edge beam cast in place integrally with the superposed layer.

16 to 18 are partial structural schematic diagrams of buildings according to different embodiments of the present disclosure.

As shown in FIGS. 16 and 18 , at least part of the connector 1003 of the prefabricated dense-ribbed panel 1000 is located inside the supporting beam 9000 .

That is to say, the prefabricated dense-rib board 1000 may include a first direction and a second direction. For example, the first direction is the length direction of the prefabricated dense-rib board 1000 and the second direction is the width direction of the prefabricated dense-rib board 1000. Of course, When the prefabricated dense-rib board 1000 has other shapes, the first direction and the second direction only need to be different.

When the periphery of the prefabricated dense-ribbed panel 1000 does not include the connector 1003, a stress-bearing system is formed between the beam structures of the building, and the prefabricated dense-ribbed panel 1000 is formed as a filling structure; correspondingly, when the first direction of the prefabricated dense-ribbed panel 1000 When connectors 1003 are provided at both ends, the prefabricated dense rib plate 1000 and the supporting beam 9000 can form an integral one-way stress-bearing system. On the other hand, when the connectors 1003 are also provided at both ends of the prefabricated dense-ribbed panel 1000 in the second direction, the connectors 1003 in the second direction can be anchored or connected in the rib beam 2000, so that the precast dense-ribbed panel 1000 forms a two-way stress system.

Therefore, the connector 1003 of the prefabricated dense-ribbed panel 1000 can be connected or anchored to the supporting beam 9000. Of course, the connectors 1003 can be connected or anchored to each other at the position of the supporting beam 9000. For example, the connectors 1003 of the prefabricated dense-ribbed panels 1000 of adjacent prefabricated dense-ribbed building structures can be directly connected or anchored, or It is connected or anchored by a frame member provided inside the support beam 9000, wherein the frame member may be a steel bar provided along the length direction of the support beam 9000 (or along a direction perpendicular or substantially perpendicular to the connection). direction of the member 1003), the end of the connecting member 1003 may be formed with a hook, and the hook may be hooked on the frame member, so that the connecting members 1003 of adjacent prefabricated dense-ribbed panels 1000 can interact with each other. Connecting or anchoring, at the same time, the frame member can also form the frame of the supporting beam 9000, so that the rib beam has higher strength and load-bearing capacity.

In a specific embodiment, the frame member may be a plurality of steel bars, the plurality of steel bars may be arranged in multiple rows in the vertical direction, and each row of steel bars may include multiple steel bars. In a preferred embodiment, each row of steel bars can also be arranged corresponding to the position of the connector 1003 of the prefabricated dense-ribbed panel 1000, thereby facilitating the connection of the connector 1003 with the frame member. More preferably, when a certain row of steel bars of the frame member includes multiple bars, the connecting member 1003 is connected to the farthest steel bar, so that the connecting member 1003 can have the maximum length within the supporting beam 9000, so as to This improves the reliability of anchoring and can also increase the connection strength between the prefabricated dense rib plate 1000 and the supporting beam 9000.

The supporting beam 9000 is provided with a bracket structure, and supports the assembled dense-rib building structure through the bracket structure. Moreover, the supporting beams 9000 can be supported by support columns, so that the building can have stronger bending resistance.

The supporting beam 9000 may be of integral cast-in-place concrete type, laminated reinforced concrete beam type, or entire section prefabricated assembly type.

In the present disclosure, when the area of the space structure is 0.8-2.5 square meters, that is, when the space structure is formed into a square and its side length is about 0.9-1.5m, the prefabricated dense rib plate is formed into a dense Ribbed prefabricated dense-ribbed panels; correspondingly, when the area of the space structure is 56-64 square meters, that is, when the space structure is formed into a square with a side length of 7-8m, the prefabricated dense-ribbed panels are formed into the primary and secondary beam floors. build. That is, the cross-sectional area of the rib structure 1002 is relatively large, and it can be called a beam at this time.

In this embodiment, only the rib beams 2000 are provided between two adjacent prefabricated dense rib panels 1000 .

Usually, precast dense ribs are mainly affected by their own weight and live load. Under the action of these gravity, the upper part of the precast dense ribs generates compressive stress and the lower part generates tensile stress. The two form a resisting moment. Concrete is a brittle material, which is suitable for compression but not for tension. Therefore, the tension in the lower part needs to be borne by the steel bars, and the pressure in the upper part is borne by the concrete. Then the concrete in the lower part becomes a burden (cumbersome), that is, it becomes a redundant self-weight load.

When the prefabricated density-ribbed building structure of the present disclosure is used, through the arrangement of T-shaped rib beams, the T-shaped cross-section exactly meets this mechanical characteristic, eliminating a large amount of redundant concrete in the lower part.

When there is a laminated layer in the assembled dense-ribbed building structure of the present disclosure, the T-shaped rib beam and the laminated layer work together, and there is a T-shaped rib beam and a prefabricated dense-ribbed panel provided with the laminated layer within the same width. The combination, the load is a fixed value, the T-shaped rib beams of the same width and the prefabricated dense-ribbed panels with superimposed layers have basically the same local bending resistance. It can also be said that there are two bending structures of the same width, combined into The carrying capacity is greatly increased when the whole unit works together.

When considering the overall effect of the laminated layer: the prefabricated components will be deformed in advance because they replace the formwork. After the laminated layer is poured, they can no longer reach the stiffness and bearing capacity of the same structure as the cast-in-place full-size structure, and there is a certain degree of damage, while the cast-in-place structure has no folding. Damage, that is to say, the prefabricated dense-ribbed panels with superimposed layers have a bearing capacity loss, while the bearing capacity of the post-cast T-shaped rib beams or rib beams has not been damaged, which enhances the overall bearing capacity.

Based on the above analysis, the assembled density-ribbed building structure of the present disclosure is a cooperative structure. T-shaped rib beams or rib beams are also main structural components and play an important role. Their mechanical contribution is great, and T-shaped rib beams or rib beams The rib beam can also connect or anchor the steel bars of the prefabricated dense-ribbed panels or rib structures on both sides to form a more superior two-way stress-bearing structure.
