Description

Technical Field

[0001] The present invention relates to the technical field of composite panels, in particular to a high-strength prefabricated composite panel structure. Background Art

[0002] Composite slabs are prefabricated, monolithic floor slabs composed of precast panels and cast-in-place reinforced concrete layers. Composite slabs offer excellent integrity, with smooth upper and lower surfaces, facilitating finishing and finishing. They are suitable for high-rise buildings and large-span structures requiring high overall rigidity. However, common composite slab structures suffer from low compressive strength and resistance to thermal deformation, as well as poor sound insulation. Furthermore, during the pouring of internal support structures, such as rebar, dead space within the support structures prevents the concrete slurry from completely spreading and filling the space, resulting in a weak bond between the two. Summary of the Invention

[0003] The purpose of the present invention is to provide a high-strength prefabricated composite panel structure in order to solve the problems of low compressive performance and structural strength of common composite panel structures, poor adaptability to structural thermal deformation, poor sound insulation effect, and the inability of concrete slurry to completely spread and fill due to dead corners in the support structure when pouring internal steel bars and other support structures, resulting in low bonding tightness between the two.

[0004] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a high-strength prefabricated composite plate structure, comprising:

[0005] A plurality of reinforcement cylinders, each comprising a cylinder body, a first positioning ring on the upper end surface of the cylinder body, and a second positioning ring on the lower end surface of the cylinder body;

[0015] As a further description of the above technical solution:

[0016] The first guide rib and the second guide rib are inclined to the normal line of the corresponding position of the load-bearing side plate.

[0017] As a further description of the above technical solution:

[0018] The projections of the upper truss structure and the lower truss structure on the wide surface of the composite plate are perpendicular to each other.

[0019] As a further description of the above technical solution:

[0020] The upper truss structure includes a plurality of beams passing through the first positioning ring and a first reinforcement rod arranged in a wave shape between the beams. A first connecting member is arranged between the first reinforcement rod and the first positioning ring. The first connecting member is a V-shaped or U-shaped rod structure.

[0021] As a further description of the above technical solution:

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] See also Figure 1-4 The present invention provides a technical solution: a high-strength prefabricated composite plate structure, comprising:

[0037] Several reinforcement cylinders 1, each comprising a cylinder body 11, a first positioning ring 14 on the upper end surface of the cylinder body 11, and a second positioning ring 15 on the lower end surface of the cylinder body 11;

[0038] An upper truss structure 2 is provided on the first positioning ring 14 to associate a plurality of the reinforcement tubes 1 in a straight line;

[0039] The lower truss structure 3 is passed through the second positioning ring 15 and associates a plurality of the reinforcement tubes 1 on another straight line;

[0040] The concrete surface layer 4 covers the surfaces of the reinforcement tube 1 , the upper truss structure 2 and the lower truss structure 3 , and a prefabricated plate (not shown in the figure) is arranged inside the concrete surface layer 4 , which can be positioned against the upper and lower end surfaces of the reinforcement tube 1 .

[0041] The cylinder body 11 includes several spiral load-bearing side plates with a concave middle and fixed ends. By adding a reinforcement cylinder 1, the compressive performance of the composite plate structure can be improved, and it has adaptability to the thermal deformation of the concrete composite plate, strong sound wave barrier performance, and high structural strength.

[0042] Several first guide ribs 12 are arranged along the width of the inner side of the load-bearing side panel, and several second guide ribs 13 are arranged closely along the width of the outer side of the load-bearing side panel. This improves the structural strength of the reinforcement tube 1. Furthermore, combined with the spirally arranged ribs on the upper and lower trusses 2 and 3, the concrete can be fully guided to every corner and blind spot during pouring, improving the connection and tightness between the internal brackets of the composite slab and the concrete surface layer 4.

[0043] The first guide rib 12 and the second guide rib 13 are inclined to the normal of the corresponding position of the load-bearing side plate, so as to further improve the overall compression resistance and thermal deformation performance of the reinforcement tube 1.

[0044] The projections of the upper truss structure 2 and the lower truss structure 3 on the wide surface of the composite plate are perpendicular to each other. The staggered and interlaced structures of the upper and lower truss structures and the reinforcement tubes can improve the assembly stability of the box-type structure and the overall structural strength of the composite plate.

[0045] The upper truss structure 2 includes a plurality of beams 21 passing through the first positioning ring 14 and first reinforcing rods 22 arranged in a wave shape between the beams 21. A first connecting member 23 is arranged between the first reinforcing rod 22 and the first positioning ring 14. The first connecting member 23 is a V-shaped or U-shaped rod structure.

[0046] The lower truss structure 3 includes a plurality of longitudinal beams 31 passing through the second positioning ring 15 and a second reinforcement rod 32 arranged in a wave shape between the longitudinal beams 31. A second connecting member 33 is arranged between the second reinforcement rod 32 and the second positioning ring 15. The second connecting member 33 is a V-shaped or U-shaped rod structure, which further improves the connection tightness between the truss structure and the reinforcement tube 1, thereby improving the structural strength of the composite plate.

[0047] The manufacturing process of a high-strength prefabricated composite panel structure of this embodiment includes: prefabrication of the reinforcement tube 1; assembly of the truss structure on the hole of the positioning ring through the cross beam 21 and the longitudinal beam 31; fixing and positioning the cross beam 21 and the longitudinal beam 31 by common methods such as welding or screwing the reinforcement rod, and fixing and positioning the truss structure and the reinforcement tube 1 by the reinforcement rod; finally, positioning the above structure on the production mold and pouring concrete together with the prefabricated panel to form the composite panel.

[0048] In summary, due to the adoption of the above technical solution, the high-strength prefabricated composite plate structure of this embodiment has the following beneficial effects compared with the prior art:

[0049] 1. This composite slab structure is based on the basic support structure of prefabricated slabs and steel frames and is equipped with reinforcement tubes, which can improve the compressive performance of the composite slab structure, adapt to the thermal deformation of the concrete composite slab, have strong sound wave barrier performance, and high structural strength.

[0050] 2. The design of the guide ribs on the reinforcement tube not only improves the structural strength of the reinforcement tube, but also cooperates with the spirally arranged ribs of the truss structure to fully guide the concrete to every corner and dead angle during concrete pouring, thereby improving the connection and tightness between the internal support of the composite slab and the concrete surface layer.

[0051] 3. The staggered and interlaced structure of the upper and lower truss structures and the reinforcement tubes can improve the assembly stability of the box structure and the overall structural strength of the composite plate.
