Abstract
Description
Technical Field
[0001] The utility model belongs to the field of prefabricated buildings, and particularly relates to a concrete ribbed composite floor slab and a composite slab. Background Art
[0002] For the concrete ribbed composite floor slab, holes are generally drilled in the ribs to enable the electrical and mechanical pipelines to be arranged horizontally. However, this method is likely to weaken the concrete ribs, resulting in rib fracture. Moreover, it is inconvenient for production, so that the ribbed composite slab has not been well promoted.
[0003] There is also a solution that uses a steel bar truss or a steel pipe truss to connect the bottom plate and the ribs to form a space for the pipelines under the ribs to pass through. However, this solution has a high cost and is troublesome to manufacture. Therefore, the present utility model comes into being. Summary of the Utility Model
[0004] The purpose of the present utility model is to provide a composite slab that is convenient for pipeline arrangement, can maintain a large flexural stiffness of the precast bottom plate, and has a low production cost.
[0005] To this end, the present utility model first provides a concrete ribbed composite bottom plate, which is characterized in that it includes a precast bottom plate and a plurality of concrete ribs formed on the precast bottom plate; an inclined pipeline groove is provided on the concrete rib, and the inclined pipeline grooves on adjacent concrete ribs form a pipeline walking path; the cross-section perpendicular to the rib length direction at the inclined pipeline groove of the concrete rib includes at least one rib section cross-section and one groove section cross-section.
[0006] Preferably, a plurality of the inclined pipeline grooves are provided on the concrete rib along the rib length direction, and the adjacent inclined pipeline grooves on the concrete rib form a herringbone-shaped inclined pipeline groove group.
[0007] Preferably, in the herringbone-shaped inclined pipeline groove groups on adjacent concrete ribs, the inclined angles of the inclined pipeline grooves in the same orientation are the same.
[0008] Preferably, the pipeline walking path is formed by the inclined pipeline grooves on a plurality of concrete ribs in the same orientation and with opposite groove openings.
[0009] Preferably, the inclined pipeline grooves on a plurality of concrete ribs in the same orientation and with opposite groove openings form a plurality of first pipeline walking paths arranged side by side and a plurality of second pipeline walking paths arranged side by side; the plurality of first pipeline walking paths and the plurality of second pipeline walking paths are staggered.
[0010] Preferably, the cross-section perpendicular to the rib length direction at the inclined pipeline groove of the concrete rib includes at least two rib section cross-sections and one groove section cross-section; the groove section cross-section is located between the two rib section cross-sections.
[0011] The utility model also provides a composite plate, characterized in that it includes a cast-in-place layer, a wire pipe and a concrete rib composite base plate; the wire pipe passes through the oblique wire pipe groove on the concrete rib, and the cast-in-place layer is formed on the prefabricated base plate and at least covers the concrete rib and the wire pipe.
[0012] The technical effects of the above technical solution of the utility model come from one or more of the following combinations:
[0013] Cutting slots in the ribs instead of holes makes it easier to route wire ducts in the floor slab than passing through the bottom of the top chord reinforcement of the truss in traditional composite slabs.
[0014] The obliquely arranged wire tube grooves enable the wire tubes to be arranged in multiple directions.
[0015] Although a wire pipe groove is set up on each concrete rib, due to the oblique arrangement of the wire pipe groove, at least half of the ribs are not cut off in the vertical section of any span of the precast base plate, and the floor stiffness is still relatively large. The 105mm composite slab (thickness is 130mm after construction is completed) can have a support-free span of up to 4m, which greatly saves on-site construction scaffolding and is green and environmentally friendly.
[0016] The wire pipe grooves opened on the concrete ribs increase the fit between the prefabricated base plate and the cast-in-place layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] For convenience of reference and understanding, for the attached Figures 1 - 6 , the following explanations are made:

[0032] Figure 2 Fig. shows the three-dimensional view of the concrete rib composite floor slab structure, and at this time, the pipeline 3 is arranged.
[0033] Figure 3 Taking L1 and L2 as the section lines, where the red line is the section 20a of the groove segment and the green line is the section 20b of the rib segment; Figure 4 Similarly to Figure 3 .
[0034] Figure 5 and Figure 6 show two different directions of pipeline routing methods.
[0035] Embodiment 1:
[0036] Please refer to Figures 1 - 6 , this embodiment provides a concrete rib composite floor slab, including a precast floor slab 1 and multiple concrete ribs 2 formed on the precast floor slab 1; an inclined pipeline groove 21 is formed on the concrete rib 2, and the inclined pipeline grooves 21 on adjacent concrete ribs 2 form a pipeline routing path; the cross-section perpendicular to the rib length direction at the inclined pipeline groove 21 of the concrete rib 2 includes at least one rib segment cross-section 20b and one groove segment cross-section 20a.
[0037] The precast floor slab 1 serves as the bottom formwork for the composite slab without support during casting, and it can be a prestressed slab or a reinforced concrete floor slab. There is no limitation in this embodiment, and the prestressed slab is preferred.
[0038] The concrete rib 2 can be integrally formed with the precast floor slab 1 by formwork casting once or twice; or it can be integrally formed by a concrete slab forming device. This embodiment also does not impose any limitation on the forming method of the concrete rib 2.
[0039] Please combine Figure 3 and Figure 4 , a plurality of oblique wire pipe grooves 21 are provided on the concrete rib 2 along the rib length direction, and adjacent oblique wire pipe grooves 21 on the concrete rib 2 form an eight-shaped oblique wire pipe groove group. The eight-shaped oblique wire pipe groove group is continuously arranged along the rib length direction. Furthermore, in the eight-shaped oblique wire pipe groove group on adjacent concrete ribs 2, the oblique wire pipe grooves 21 in the same direction have the same bevel angle. The purpose is to facilitate the linear arrangement of the wire pipe 3, but it is not a limitation. The bevel angle can be 60°, 45°, etc., and can be adjusted according to actual needs in combination with the groove width and the specific size of the wire pipe 3. Of course, the same bevel angle of the oblique wire pipe grooves 21 in the same direction is a preferred implementation of this embodiment, and can also be different, so as to achieve the wiring of the wire pipe 3.
[0040] This embodiment avoids the wire pipe groove being located in the same section perpendicular to the span direction by obliquely arranging the wire pipe 3, thereby avoiding the cross section perpendicular to the span direction from forming an obvious weak section. Therefore, the wire pipe path is formed on the multiple concrete ribs 2 in the same direction and with opposite notches.
[0041] For details, please refer to Figure 5 and Figure 6 The oblique wire pipe grooves 21 on the multiple concrete ribs 2 with the same direction and opposite notches form multiple first wire pipe paths arranged side by side and multiple second wire pipe paths arranged side by side. Further, the multiple first wire pipe paths and the multiple second wire pipe paths are arranged in an alternating manner. The multiple first wire pipe paths and the multiple second wire pipe paths are both defined as the above-mentioned wire pipe paths.
[0042] Please combine Figure 3 and Figure 4 The cross section perpendicular to the rib length direction at the oblique wire tube groove 21 of the concrete rib 2 is a rib section cross section 20b and a groove section cross section 20a, so that the cross section at the oblique wire tube groove 21 is a discontinuous cross section of the rib and groove combination, and the rib is weakened by a small amount (generally the rib width is 200, the groove width is 54mm), thereby maintaining the bending stiffness and bending bearing capacity of the prefabricated bottom plate 1. At the oblique wire tube groove 21 of the concrete rib 2, the cross section perpendicular to the rib length direction is at least two rib section cross sections 20b and one groove section cross section 20a. The groove section cross section 20a is located between the two rib section cross sections 20b. Figure 4 The red line segment is the groove section 20a, and the green line segment is the rib section 20b.
[0043] Beneficial effects of this embodiment:
[0044] Slots are made on the ribs instead of holes, so that it is more convenient to arrange the wire tube 3 on the floor slab than to pass the wire tube through the bottom of the upper chord steel bars of the truss in the traditional composite slab.
[0045] The obliquely arranged wire tube grooves enable the wire tube 3 to be arranged in multiple directions.
[0046] Although the line pipe grooves are provided in each concrete rib 2, due to the diagonal arrangement of the line pipe grooves, at least half of the ribs in any vertical section along the span of the precast floor slab 1 are not cut off. The floor slab stiffness is still relatively large. The unsupported span of the 105 mm composite slab (with a thickness of 130 mm after construction) can reach 4 m, greatly saving the on-site construction scaffolding and being green and environmentally friendly.
[0047] The line pipe grooves provided on the concrete ribs 2 increase the bite between the precast floor slab 1 and the cast-in-place layer.
[0048] Embodiment 2:
[0049] This embodiment provides a composite slab, including a cast-in-place layer, a line pipe 3 and a concrete rib composite floor slab. Among them, the line pipe 3 passes through the diagonal line pipe grooves 21 on the concrete ribs 2, and the cast-in-place layer is formed on the precast floor slab 1 and at least covers the concrete ribs 2 and the line pipe 3.
[0050] Furthermore, the concrete rib composite floor slab includes a precast floor slab 1 and multiple concrete ribs 2 formed on the precast floor slab 1; diagonal line pipe grooves 21 are provided on the concrete ribs 2, and the diagonal line pipe grooves 21 on adjacent concrete ribs 2 form a line pipe routing path; the cross-section perpendicular to the rib length direction at the diagonal line pipe grooves 21 of the concrete ribs 2 at least includes a rib section cross-section 20b and a groove section cross-section 20a.
[0051] The precast floor slab 1 serves as the bottom formwork for the unsupported casting of the composite slab, and it can be a prestressed slab or a reinforced concrete floor slab. There is no limitation in this embodiment, and the prestressed slab is preferred.
[0052] The concrete ribs 2 are formed integrally with the precast floor slab 1 by template casting either once or twice; or they can be integrally formed by a concrete slab forming device. This embodiment also does not impose any limitation on the forming method of the concrete ribs 2.
[0053] Please refer to Figure 3 and Figure 4 , a plurality of diagonal line pipe grooves 21 are provided along the rib length direction of the concrete ribs 2, and the adjacent diagonal line pipe grooves 21 on the concrete ribs 2 form a herringbone diagonal line pipe groove group. The herringbone diagonal line pipe groove group is continuously arranged along the rib length direction. Furthermore, in the herringbone diagonal line pipe groove groups on adjacent concrete ribs 2, the diagonal angles of the diagonal line pipe grooves 21 in the same orientation are the same. The purpose is to facilitate the straight-line arrangement of the line pipe 3, but it is not limited thereto. The diagonal angles can be 60°, 45°, etc., and can be adjusted according to the actual requirements in combination with the groove width and the specific dimensions of the line pipe 3. Of course, the diagonal angles of the diagonal line pipe grooves 21 in the same orientation being the same is a preferred embodiment of this embodiment, and they can also be different, as long as the pipe routing of the line pipe 3 can be achieved.
[0054] This embodiment avoids the wire pipe groove being located in the same section perpendicular to the span direction by obliquely arranging the wire pipe 3, thereby avoiding the cross section perpendicular to the span direction from forming an obvious weak section. Therefore, the wire pipe path is formed on the multiple concrete ribs 2 in the same direction and with opposite notches.
[0055] For details, please refer to Figure 5 and Figure 6 The oblique wire pipe grooves 21 on the multiple concrete ribs 2 with the same direction and opposite notches form multiple first wire pipe paths arranged side by side and multiple second wire pipe paths arranged side by side. Further, the multiple first wire pipe paths and the multiple second wire pipe paths are arranged in an alternating manner. The multiple first wire pipe paths and the multiple second wire pipe paths are both defined as the above-mentioned wire pipe paths.
[0056] Please combine Figure 3 and Figure 4 The cross section perpendicular to the rib length direction at the oblique wire tube groove 21 of the concrete rib 2 is a rib section cross section 20b and a groove section cross section 20a, so that the cross section at the oblique wire tube groove 21 is a discontinuous cross section of the rib and groove combination, and the rib is weakened by a small amount (generally the rib width is 200, the groove width is 54mm), thereby maintaining the bending stiffness and bending bearing capacity of the prefabricated bottom plate 1. At the oblique wire tube groove 21 of the concrete rib 2, the cross section perpendicular to the rib length direction is at least two rib section cross sections 20b and one groove section cross section 20a. The groove section cross section 20a is located between the two rib section cross sections 20b. Figure 4 The red line segment is the groove section 20a, and the green line segment is the rib section 20b.
[0057] Beneficial effects of this embodiment:
[0058] Slots are made on the ribs instead of holes, so that it is more convenient to arrange the wire tube 3 on the floor slab than to pass the wire tube through the bottom of the upper chord steel bars of the truss in the traditional composite slab.
[0059] The obliquely arranged wire tube grooves enable the wire tube 3 to be arranged in multiple directions.
[0060] Although each concrete rib 2 is provided with a wire pipe groove, due to the oblique arrangement of the wire pipe groove, at least half of the ribs along any vertical section of the span of the precast base plate 1 are not cut off, and the floor slab stiffness is still relatively large. The 105mm composite slab (130mm thick after construction) can have a support-free span of up to 4m, which greatly saves on-site construction scaffolding and is green and environmentally friendly.
[0061] The wire pipe grooves provided on the concrete ribs 2 increase the engagement between the prefabricated base plate 1 and the cast-in-place layer.
[0062] Furthermore, the present utility model has been described in detail with reference to the embodiments accompanied by drawings. Those of ordinary skill in the art can make various variations to the present utility model based on the above description. Therefore, certain details in the embodiments should not constitute a limitation to the present utility model, and the protection scope of the present utility model will be defined by the scope defined in the appended claims.
