Description

Technical Field

[0001] This utility model relates to the field of composite panel technology, and more specifically, to an assembled composite panel. Background Technology

[0002] Composite slabs are precast slabs made from raw materials such as yellow sand, cement, and pulp. The precast slabs and the negative reinforcement of the supports are poured together to form a whole, thus creating composite slabs. Composite slabs are used to replace traditional steel, aluminum, and wooden formwork.

[0003] In existing technologies, after the composite slabs are hoisted onto beams or other locations, their positions need to be checked and confirmed. If they do not meet the requirements, their positions should be adjusted in a timely manner to ensure the reliability of the precast slab overlaps and prevent wide gaps from appearing at the overlap positions. However, existing technologies often adjust the overlap spacing by visual inspection, which can easily lead to inconsistent spacing. Furthermore, the existing technologies use binding methods to reinforce the slab joints, which is not only inefficient but also has a weak reinforcement effect.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The front side of the composite slab body is provided with equidistant connecting grooves, and additional steel bars are equidistantly arranged through the inner cavity of the composite slab body.

[0008] Preferably, the connecting groove extends through the bottom of the composite plate body, and the rear side of the composite plate body is equidistantly connected with interlocking blocks, which are movably interlocked with the inner wall of the connecting groove.

[0009] Preferably, the structure of the fitting block matches the structure of the connecting groove, a positioning rod is fixedly connected to the rear side of the inner wall of the connecting groove, and positioning holes are dug on the outer side of the fitting block, and the positioning rod is movably connected through the positioning holes.

[0010] Preferably, a fixing block is equidistantly embedded on the right side of the composite plate body, and guide holes are symmetrically provided on the outer side of the fixing block, and the additional reinforcing bars are respectively movably connected to the guide holes.

[0011] Preferably, a limiting hole is provided through the middle of the outer side of the fixing block, and a limiting post is fixedly connected to the middle of the inner side of the fixing block, with the limiting post and the limiting hole being movably engaged.

[0012] Preferably, splicing strips are fixedly connected to the top two sides of the composite plate body, the splicing strips are mirror images of each other, the splicing strips are specifically L-shaped, and the top edge of each splicing strip is notched.

[0013] The beneficial effects of this utility model are as follows: it can improve the stability of the front and rear splicing of the composite slab body, quickly position the splicing of the composite slab body left and right, avoid the skewing during the left and right splicing of the composite slab body, make the left and right splicing operation more accurate, reduce the board gaps between the left and right splicing of the composite slab body, and fill the board gaps with concrete or adhesive at the notch at the top edge of the splicing strip, avoiding the filling material from being injected directly into the board gaps and causing the filling material to bulge on the surface of the composite slab body, affecting the aesthetics.

[0022] According to an embodiment of the present invention, an assembled composite panel is provided. Example 1

[0023] like Figure 1-4 As shown, according to an embodiment of the present invention, a prefabricated composite slab includes a composite slab body 1, a steel truss 2, and bottom reinforcement 3. The steel truss 2 is symmetrically arranged on both sides of the bottom of the composite slab body 1, and the bottom reinforcement 3 is equidistantly arranged on both sides of the outer wall of the steel truss 2. A connecting groove 4 is equidistantly excavated on the front side of the composite slab body 1, and additional steel bars 5 are equidistantly arranged through the inner cavity of the composite slab body 1. The connecting groove 4 penetrates the bottom of the composite slab body 1, and a fitting block 6 is equidistantly connected on the rear side of the composite slab body 1.

A positioning rod 7 is fixedly connected to the rear side of the inner wall of the connecting groove 4. A positioning hole groove 8 is excavated on the outer side of each fitting block 6, and the fitting block 6 is movably sleeved with the positioning rod 7 through the positioning hole groove 8.

[0024] In this embodiment, when splicing the composite plate body 1 front and back, one composite plate body 1 can be movably embedded in the connecting groove 4 on one side of another composite plate body 1 through the interlocking block 6, and the positioning hole groove 8 on the outer side of the interlocking block 6 is movably sleeved and fixed with the positioning rod on the inner wall of the connecting groove 4.

Example 2

[0025] like Figure 1-4 As shown, according to an embodiment of the present utility model, a prefabricated composite slab includes a composite slab body 1, a steel truss 2, and bottom reinforcement 3. The steel truss 2 is symmetrically arranged on both sides of the bottom of the composite slab body 1, and the bottom reinforcement 3 is equidistantly arranged on both sides of the outer wall of the steel truss 2. A connecting groove 4 is equidistantly excavated on the front side of the composite slab body 1. Additional steel bars 5 are equidistantly arranged through the inner cavity of the composite slab body 1. Fixing blocks 9 are equidistantly embedded and fixed on the right side of the composite slab body 1. Guide holes 10 are symmetrically arranged on the outer side of the fixing blocks 9. The additional steel bars 5 are movably sleeved with the guide holes 10 respectively. A limiting hole 11 is circumferentially arranged in the middle of the outer side of the fixing block 9. A limiting post 12 is fixedly connected to the middle of the inner side of the fixing block 9. The limiting post 12 is movably fitted with the limiting hole 11.

[0026] In this embodiment, during the left and right splicing of the composite plate body 1, the fixing block 9 on one side of the composite plate body 1 fits into the fixing block 9 on the other side of the composite plate body 1, and the limiting post 12 outside the fixing block 9 on one side is fitted into the limiting hole 11 on the other fixing block 9. The additional steel bars 5 on both sides of the composite plate body 1 are spliced ​​into the guide hole 10. This allows the composite plate body 1 to be quickly positioned left and right, avoiding skewing during the left and right splicing process, and making the left and right splicing operation more accurate. Example 3

[0027] like Figure 1-4 As shown, according to an embodiment of the present utility model, a prefabricated composite slab includes a composite slab body 1, a steel truss 2, and bottom reinforcement 3. The steel truss 2 is symmetrically arranged on both sides of the bottom of the composite slab body 1, and the bottom reinforcement 3 is equidistantly arranged on both sides of the outer wall of the steel truss 2.

[0028] In this embodiment, during the process of splicing the composite slab body 1 from left to right, the splicing strips 13 on both sides will interlock and splice with each other, which can reduce the gap between the left and right splicing of the composite slab body 1. Furthermore, the notch 14 at the top edge of the splicing strip 13 can be used to fill the gap with concrete or adhesive, avoiding the direct injection of filler into the gap, which would cause the filler to bulge on the surface of the composite slab body 1 and affect the aesthetics.

[0029] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is used to splice the composite plate body 1 front and back, one composite plate body 1 can be movably embedded in the connecting groove 4 on one side of another composite plate body 1 through the interlocking block 6, and the positioning hole groove 8 on the outer side of the interlocking block 6 is movably sleeved and fixed with the positioning rod on the inner wall of the connecting groove 4. During the process of splicing the composite plate body 1 left and right, the fixing block 9 on one side of the composite plate body 1 fits with the fixing block 9 on the other side of the composite plate body 1, and the limiting post 12 outside the fixing block 9 on one side fits into the limiting hole 11 on the other fixing block 9. The additional steel bars 5 on both sides of the composite plate body 1 are spliced ​​with the guide hole 10. During the process of splicing the composite plate body 1 left and right, the splicing strips 13 on both sides will fit together, which can reduce the plate gap of the left and right splicing of the composite plate body 1. Furthermore, the notch 14 at the top edge of the splicing strip 13 can be used to fill the plate gap with concrete or adhesive.
