[0034] An embodiment of the present invention provides a cast-in-place frame beam assembled composite waffle plate structure, which includes: a composite waffle plate 1, a cast-in-place frame beam 2 and a combined waffle tube formwork 3, and the cast-in-place frame beam 2 surrounds the composite waffle plate 1 and can form a reliable connection.

[0035] like Figure 1 , Figure 3As shown, the laminated waffle plate 1 is composed of a prefabricated part 11 and an upper laminated layer 12. The prefabricated part 11 is a prefabricated component produced in a factory to improve construction efficiency and reduce on-site construction time. It includes a prefabricated rib beam 112, and the upper laminated layer 12 is a cast-in-place part, which includes a cast-in-place rib beam 121. The prefabricated rib beam 112 and the cast-in-place rib beam 121 are arranged orthogonally.

[0036] The combined waffle cone template 3 is composed of a bottom mold 31 and an upper barrel body 32. The separate design of the bottom mold 31 and the upper barrel body 32 allows adjustment according to specific needs during the design stage, thereby increasing the flexibility of the design.

[0037] According to the above structure, the combined waffle tube formwork 3 is installed on the prefabricated part 11. When the steel bars in the upper superimposed layer 12 and the upper barrel body 32 are installed in place, the upper superimposed layer 12 and the cast-in-place frame beam 2 are integrally cast with concrete to form an integral bidirectionally stressed beam-slab floor system, that is, a cast-in-place frame beam assembled superimposed waffle slab structure. The present invention makes the weight of the prefabricated components reasonable by setting the cast-in-place upper superimposed layer 12, and forms an integral floor structure system with reliable node connection and bidirectional frame stress, thereby achieving the design goal of "equivalent to cast-in-place".

[0038] In the embodiment of the present invention, the material of the combined waffle tube template 3 is a composite material SMC made of glass fiber and unsaturated polyester resin as main materials and cured at high temperature, which has the characteristics of light weight, high strength, corrosion resistance, fire resistance and the like.

[0039] In an embodiment of the present invention, the prefabricated part 11 is formed by splicing a number of prefabricated strip bottom plates 111, and each prefabricated strip bottom plate 111 is composed of a prefabricated rib beam 112 and a prefabricated plate strip 113 between the prefabricated rib beams. After the construction is completed, the two ends of the prefabricated strip bottom plates 111 can be placed on the cast-in-place frame beam 2, and the bottom distribution steel bars can be extended into the cast-in-place frame beam 2 for anchoring, so as to ensure the reliability and safety of the node connection. In addition, two adjacent prefabricated strip bottom plates 111 are tightly spliced ​​together, and at the splicing of adjacent prefabricated strip bottom plates 111, the bottom distribution steel bars of the adjacent prefabricated strip bottom plates 111 are anchored upward into the upper composite layer 12, so as to ensure the reliable connection between adjacent prefabricated components. The upper composite layer 12 is arranged on the prefabricated strip bottom plates 111, so that the entire beam-slab floor system becomes an integrated two-way force system.

[0040] In the embodiment of the present invention, prefabricated rib beams 112 are arranged in the prefabricated strip bottom plate 111, or the prefabricated strip bottom plate 111 or its main part is directly used as the prefabricated rib beams 112, and the prefabricated rib beams 112 are at least arranged between each row of waffle cones, and their length direction is parallel to the long side direction of the prefabricated strip bottom plate 111. Correspondingly, cast-in-place rib beams 121 are arranged in the upper laminated layer 12, and preferably, the upper laminated layer 12 is composed of cast-in-place rib beams 121 and cast-in-place plate strips 122 between the cast-in-place rib beams 121. The cast-in-place rib beams 121 are at least arranged between each row of waffle cones and are perpendicular to the long side direction of the prefabricated strip bottom plate 111, thereby forming an orthogonal force-bearing structure of the prefabricated rib beams 112 and the cast-in-place rib beams 121.

[0041] The embodiment of the present invention can enhance the bearing capacity and anti-seismic performance of the entire structure by arranging prefabricated rib beams 112 and cast-in-place rib beams 121. In addition, it can help improve its structural rigidity, so that the structure has a higher anti-micro-vibration performance. Among them, multiple prefabricated rib beams 112 are integrated and arranged in the prefabricated strip bottom plate 111 and produced in the factory, which can reduce the on-site construction time, improve product quality and construction efficiency, and the size of the prefabricated strip bottom plate 111 can be customized according to design and construction requirements, with the flexibility of standardized components and modular combination of prefabricated structures.

[0042] In the embodiment of the present invention, the prefabricated rib beam 112 in the prefabricated strip bottom plate 111 can be regarded as a composite beam, which has a top stress-bearing rib 1121, a bottom stress-bearing rib 1122 and a rib beam stirrup 1123. The bottom stress-bearing rib 1122 is arranged in the prefabricated strip bottom plate 111, and the top stress-bearing rib 1121 is arranged in the upper composite layer 12. Further, the prefabricated strip bottom plate 111 is also arranged with a plate bottom distribution steel bar 1131, which is arranged between every two adjacent waffle tubes, one end of which extends into the cast-in-place frame beam 2 for reliable anchoring, and the other end is anchored upward into the upper composite layer 12. The bottom stress-bearing rib 1122 and the top stress-bearing rib 1121 are parallel to the long side direction of the prefabricated strip bottom plate 111, and the plate bottom distribution steel bar 1131 is perpendicular to the long side direction of the prefabricated strip bottom plate 111. The lower part of the rib beam stirrup 1123 is located at the prefabricated strip bottom plate 111, and the upper part extends into the upper composite layer 12, so that the prefabricated rib beam 112 and the upper composite layer 12 are well connected. The rib beam stirrup 1123 is arranged along the entire length parallel to the length direction of the prefabricated rib beam and together with the load-bearing bottom reinforcement 1122 and the load-bearing top reinforcement 1121, it forms the steel skeleton of the prefabricated rib beam 112, thereby ensuring the bearing capacity and deformation resistance of the structure.

[0043] In the embodiment of the present invention, the cast-in-place rib beam 121 has two top stress bars 1211, two bottom stress bars 1212 and two rib beam stirrups 1213, all of which are arranged in the upper laminated layer 12, and the two top stress bars 1211 and the two bottom stress bars 1212 are perpendicular to the long side direction of the prefabricated strip bottom plate 111; the two rib beam stirrups 1213 are arranged along the length direction parallel to the cast-in-place rib beam 121 and together with the two top stress bars 1211 and the two bottom stress bars 1212, form the steel skeleton of the cast-in-place rib beam 121. The arrangement of the two rib beam stirrups 1213 can be optimized according to the specific needs of the structure to achieve the best structural performance.

[0044] In an embodiment of the present invention, by arranging composite beams parallel to the long side direction of the bottom plate and cast-in-place rib beams 121 arranged in a perpendicular direction to the bottom plate in the prefabricated strip bottom plate 111, finally, when the upper composite layer 12 is cast, a bidirectionally stressed floor structure is formed by orthogonally arranged prefabricated rib beams 112 and cast-in-place rib beams 121. The bidirectionally stressed beam grid / beam-slab system improves the bidirectional bearing capacity and stiffness of the floor system, while improving the convenience and flexibility of factory processing and on-site construction of prefabricated components.

[0045] Furthermore, the prefabricated strip bottom plate 111 has bottom distribution steel bars and a load-bearing bottom bar 1122 adjacent to the cast-in-place frame beam 2 extending into the cast-in-place frame beam 2 for anchoring and forming a post-cast node area, which effectively combines the advantages of prefabrication and cast-in-place technology, improves construction efficiency and structural performance, and helps to achieve the integrity between the prefabricated strip bottom plate 111 and the cast-in-place frame beam 2, thereby improving the collaborative working ability of the entire structure.

[0046] In the embodiment of the present invention, at the joint of adjacent prefabricated strip bottom plates 111, the bottom plate distribution steel bars 1131 are bent upward and anchored in the upper superimposed layer 12. At the intersection of the prefabricated strip bottom plates 111 and the cast-in-place frame beam 2, the bottom plate distribution steel bars 1131 extend into the cast-in-place frame beam 2 for anchoring. In the upper superimposed layer 12, a reinforced concrete hidden beam is formed by arranging a force-bearing top bar 1121 and a rib beam stirrup 2 1213, thereby reliably connecting the adjacent prefabricated strip bottom plates 111. Specifically, Figure 4 This structure can effectively improve the connection performance between adjacent panels and the integrity of the floor system, so that the force of the floor is continuously transmitted.

[0047] A typical application of the present invention is as follows Figure 2 As shown, the assembled laminated waffle plate of the embodiment of the present invention is arranged in the standard column spacing of the electronic factory, and three prefabricated strip bottom plates 111 are installed in each span. After the installation is completed, the steel bars in the upper laminated layer 12 are arranged, as shown in FIG. Figure 1 As shown, it includes two stress-bearing bottom reinforcements 1212, two stress-bearing top reinforcements 1211, one stress-bearing top reinforcement 1121 and two rib stirrups 1213.

[0048] In order to meet the cleanliness requirements of the electronic factory, a series of through holes are set in the floor of the production area. The prefabricated part 11 of the present invention can be prepared in the factory or on site, wherein the bottom mold 31 is pre-buried in the prefabricated part 11. Specifically, a combined waffle tube template 3 is used for hole forming, wherein the bottom mold 31 is used as a hole forming template and also serves as a bottom mold of the strip bottom plate when processing the prefabricated strip bottom plate 111, and is buried in the prefabricated strip bottom plate 111. The upper barrel body 32 is connected to the bottom mold 31 at the top of the prefabricated strip bottom plate 111. Specifically, the bottom mold 31 and the upper barrel body 32 are connected by a flange ring and self-tapping screws 33, and can also be connected by other similar structures such as a socket connection structure 34, as shown in the following example. Figure 5 and Figure 6 As shown. The combined waffle tube template of the present invention can replace the template laid on site, reducing the support frame to a certain extent. In addition, the existing waffle tube templates are mostly made of SMC plastic material, which is easy to break during on-site construction. The combined waffle tube template can facilitate the replacement of the broken template later.

[0049] According to the above structure, on site, the prefabricated part 11 is hoisted to the designed position, and the steel bars of the upper superimposed layer 12 are arranged on the prefabricated strip bottom plate 111, so that the prefabricated rib beam 112 and the cast-in-place rib beam 121 can be arranged orthogonally, and the upper barrel 32 is connected to the bottom mold 31 reserved in the prefabricated part 11 to form a combined waffle tube template 3 as a waffle plate channel template, and finally the upper superimposed layer 12 and the cast-in-place frame beam 2 are integrally cast, and after curing and finishing, a bidirectional force-bearing assembled integral frame structure and assembled superimposed waffle plate floor system are formed. The present invention can realize the design concept of "equivalent to cast-in-place", the structural force is reasonable, the structural performance is safe and reliable, and the assembled construction technology is adopted at the same time, which can improve the construction quality and construction efficiency to a certain extent, reduce on-site operations and environmental pollution, and is conducive to the further promotion of assembled technology in the field of electronic industrial plants.
