[0020] For ease of understanding of the application, the application will be described more fully below. The application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items. In addition, in the description of the present application, the meaning of "several" is at least one, such as one, two, etc., unless otherwise clearly and specifically limited.

[0022] In the present application, the technical features described in an open manner include closed technical solutions composed of the listed features, and also include open technical solutions containing the listed features.

[0023] The utility model provides an assembled energy-saving prefabricated building floor slab, which is used for assembly with prefabricated wall panels or for mutual assembly between multiple floor slabs, and after assembly, concrete is poured to fix them together. Figure 1 As shown, specifically, it includes a floor slab body 1, in which a plurality of transverse distribution bars 2 and a plurality of vertical distribution bars 3 arranged at intervals are arranged, and the transverse distribution bars 2 and the vertical distribution bars 3 are vertically staggered.

[0024] The top of the side surface of the floor slab body 1 extends to form an upper extension 4, and the bottom of the side surface of the floor slab body 1 extends along the plane direction to form a lower extension 5. A casting trough 10 is formed between the upper extension 4 and the lower extension 5. The cross-section of the casting trough 10 is an open square or a transverse U-shape. The transverse distribution ribs 2 and the vertical distribution ribs 3 extend from the casting trough 10. The upper extension 4 and the lower extension 5 are provided with mounting holes 21, and the mounting holes 21 of the upper extension 4 and the lower extension 5 correspond to each other.

[0025] In this embodiment, two or more floor slab bodies 1 are assembled, and the casting grooves 10 formed by the upper extension 4 and the lower extension 5 are opposite to each other on the side. The transverse distribution ribs 2 and the vertical distribution ribs 3 extend out of the casting grooves 10 so that a gap is formed between the two assembled floor slabs. When the concrete 6 is poured onto the surface of the floor slab, it is poured into the casting grooves 10 from the gap. The concrete 6 forms an I-shaped structure here, and is fixedly filled to surround the distribution ribs, thereby improving the connection strength and the overall structural strength. The installation holes 21 opened in the upper extension 4 and the lower extension 5 are used to assemble the reinforcement ribs extending from the prefabricated wall panels. When the concrete 6 is poured, it enters the casting grooves 10 from the installation holes 21 to fill, thereby increasing the connection strength between the reinforcement ribs and the floor slabs and enhancing the overall structural strength of the prefabricated floor slabs and prefabricated wall panels.

[0026] In order to realize the assembly of the floor slab, in one embodiment, a connecting hole 11 is opened on the side of the floor slab body 1, and the connecting hole 11 is formed at the bottom of the casting trough 10. The transverse distribution reinforcement 2 or the vertical distribution reinforcement 3 of one floor slab body 1 extends into the connecting hole 11 of another floor slab body 1 assembled with it, and is fixed in the casting trough 10 by injecting concrete 6.

[0027] In one embodiment, the transverse distribution ribs 2 and / or the vertical distribution ribs 3 are arranged in a staggered manner. Furthermore, the connection holes 11 are formed symmetrically with the transverse distribution ribs 2 / the vertical distribution ribs 3, or in other words, in the cross section, the horizontal midline of the side of the floor body 1 through the center is the symmetry center, and the connection holes 11 are symmetrically distributed with the transverse distribution ribs 2 / the vertical distribution ribs 3. In this embodiment, this arrangement not only makes the overall structure firm, but also this structure can be used as a universal assembly floor, and the two floor slabs can be assembled by rotating the front and back sides, avoiding the processing and assembly difficulties caused by various processing styles.

[0028] In order to realize the assembly of the floor slab, in one embodiment, the hole diameter of the connecting hole 11 is larger than the diameter of the transverse distribution reinforcement 2 and / or the vertical distribution reinforcement 3, the transverse distribution reinforcement 2 / vertical distribution reinforcement 3 is arranged in the connecting hole 11, and the concrete 6 is injected into the connecting hole 11 from the casting trough 10, so as to effectively enhance the connection strength.

[0029] In one embodiment, the depth of the connecting hole 11 corresponds to the length of the transverse distribution reinforcement 2 / the vertical distribution reinforcement 3 extending from the casting trough 10, so as to achieve precise assembly and avoid the concrete 6 failing to fill the gap between the distribution reinforcement and the bottom of the connecting hole 11 during the pouring process, thereby improving the overall connection strength and reliability.

[0030] In one embodiment, the length of the lower extension 5 is greater than the length of the upper extension 4, and the difference between the length of the lower extension 5 and the length of the upper extension 4 is equal to the length of the transverse distribution bar 2 / the vertical distribution bar 3 extending from the casting trough 10.

[0031] Preferably, in one embodiment, the floor slab body 1 includes a precast concrete slab layer and an interlayer sandwiched between the precast concrete slab layers. The interlayer may be provided with reinforcing materials to improve the overall strength of the floor slab, or the interlayer may be provided with sound insulation materials to improve the sound insulation effect between floors of the building.

[0032] In one embodiment, the material of the interlayer is a sound insulation and fireproof material, for example, the sound insulation and fireproof material is porous foam aluminum. Porous foam aluminum combines the properties of porous materials and metals, has low density, light material, sound absorption, heat insulation, combustion support, impact resistance and other excellent properties, and is suitable for use as a floor interlayer material, making the floor light, improving the sound insulation effect of the floor, and improving the fire retardant performance between the floors of the building.

[0033] In order to improve the structural stability of the floor, in one embodiment, fastening screws are provided on the floor body 1, and the fastening screws pass through the precast concrete slab layer and the interlayer to fix and connect the various layers of the floor structure to ensure stability and reliability.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
