Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building application technology, specifically relating to a two-way dense ribbed cavity floor slab module. Background Technology

[0002] Currently, prefabricated construction will upgrade the precision of buildings from centimeters to millimeters, which is 3-4 times higher than the precision of traditional cast-in-place concrete construction. This results in higher building quality, longer lifespan, and more outstanding thermal insulation and environmental protection performance.

[0003] Most prefabricated wall panels are manufactured to high quality in factories and then transported to the site for installation. Simply put, it involves prefabricating roof panels, wall panels, floor base layers, surface layers, and related components in a factory, then transporting the finished products to the construction site for dry assembly. This type of decoration is very convenient for wall decoration and building construction.

[0004] Generally speaking, unidirectional or bidirectional ribbed floor slabs with a rib spacing of less than 1.5 meters are called closely ribbed floor slabs, while bidirectional closely ribbed floor slabs have better stress performance because they bear the load from both directions. A search revealed a bidirectional ribbed hollow floor slab module for concrete structures, patent number 202123382900.1 and authorization announcement number CN217840518U. This module relates to the field of prefabricated building technology. The module comprises a polygonal side ribbed beam semi-formwork frame, at least two intersecting reinforced concrete inner ribbed beams, and at least one reinforced concrete base slab, all prefabricated together. The polygonal side ribbed beam semi-formwork frame is formed by at least four side ribbed beam semi-formwork frames intersecting in pairs. The two ends of the inner ribbed beams overlap two side ribbed beam semi-formwork frames. The lower ends of the side ribbed beam semi-formwork frame and the inner ribbed beams are integrally formed with the base slab through internal reinforcement and prefabrication of concrete. This invention can save construction time, reduce the number of formwork supports, shorten the construction period, and effectively reduce costs.

[0005] Analysis revealed that the structure was complex and the construction was cumbersome, resulting in a long construction period. This is a problem that needs to be addressed.

[0006] Therefore, based on the above problems, this utility model provides a bidirectional dense ribbed cavity floor slab module. Utility Model Content

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The bidirectional ribbed hollow floor slab module shown includes a base plate 10, a set of external support bosses 11, a set of internal support bosses 12, a hollow transition box 13, and a cover plate 14.

[0025] A set of external support bosses 11 are symmetrically arranged on both ends of the base plate 10.

[0026] A set of inner support bosses 12 are symmetrically arranged on one side of the base plate 10, and are located between a set of outer support bosses 11.

[0027] One side of the hollow transition box 13 abuts against the surfaces of a set of external support bosses 11 and a set of internal support bosses 12, respectively.

[0028] One side of the cover plate 14 abuts against the other side of the hollow transition box 13;

[0029] The cover plate 14 is larger than the hollow transition box 13, which seals the hollow transition box 13 and prevents concrete from entering from the top during pouring.

[0030] Working principle or structural principle: During construction, the hollow transition box 13 is first placed on a set of external support bosses 11 and a set of internal support bosses 12, and the bottom plate 10 and the hollow transition box 13 are fixed to the set of external support bosses 11 and the set of internal support bosses 12 respectively. Then the cover plate 14 is placed on the hollow transition box 13 and fixed, and finally concrete is poured.

[0031] In addition, the preferred bidirectional ribbed hollow floor slab module also includes positioning protrusions 111 respectively disposed on the end faces of the two ends of the outer support protrusions 11, and limiting grooves 131 respectively disposed in the four corners of one side of the hollow transition box 13 and matched with the positioning protrusions 111, wherein the size of the positioning protrusions 111 is smaller than the size of the limiting grooves 131.

[0032] When the base plate 10 and the hollow transition box 13 are fixed together, the relative fixation between the two is achieved, preventing the hollow transition box 13 from detaching from the base plate 10.

[0033] In addition, the matching positioning protrusions 111 and limiting grooves 131 are preferably set as circular or polygonal structures to facilitate relative insertion and fixing during construction.

[0034] In addition, preferably, the width of the outer support boss 11 is greater than the width of the inner support boss 12, thereby increasing the contact area with the hollow transition box 13 and achieving stable and reliable support and fixation for the hollow transition box 13.

[0035] In addition, preferably, the base plate 10, a set of external support bosses 11, a set of internal support bosses 12 and positioning protrusions 111 are integrally cast polypropylene fiber concrete panels; the hollow transition box 13 and the limiting groove 131 are integrally cast polypropylene fiber concrete panels; and the cover plate 14 is integrally cast polypropylene fiber concrete panels.

[0036] The above three-part structure facilitates prefabrication and transportation, while saving 30% of steel and concrete, resulting in low cost. It also boasts superior performance, exhibiting advantages such as high rigidity, minimal deformation, and excellent seismic resistance compared to general slabs, ribbed hollow slabs, lightweight infill materials, and flat slabs.

[0037] This bidirectional ribbed hollow floor module is suitable for multi-story and high-rise buildings. It is simple and fast to construct, reduces the height of BBF core molds and concrete slab components, and reduces the amount of concrete used in the floor, thus greatly reducing the floor weight, saving on ceiling space, lowering the floor height, and reducing the building's self-weight.

[0038] It should be noted that, in this document, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
