Description

Technical Field

[0001] This utility model relates to the field of building floor slab structures, and more specifically, to a fireproof composite board. Background Technology

[0002] Composite slabs are assembled monolithic floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. The precast base slab is a structural component of the floor slab and also serves as a permanent formwork for the cast-in-place reinforced concrete composite layer. It boasts excellent integrity and saves on formwork, thus its widespread use is noteworthy. For example, patent CN214531417U discloses a composite slab comprising a concrete layer and a reinforcing steel assembly within the concrete layer. The reinforcing steel assembly includes bottom reinforcement, top reinforcement, long reinforcing bars, short reinforcing bars, several steel trusses, and fixing bars; the long and short reinforcing bars are all positioned between the bottom and top reinforcement of the composite slab.

[0003] The steel truss includes a first support, a second support, a third support, and a fourth support. One end of the first support, one end of the second support, one end of the third support, and one end of the fourth support are connected to the same point of the fixed reinforcement. The other end of the first support and the other end of the second support are respectively connected to the same reinforcing rib. The other end of the third support and the other end of the fourth support are respectively connected to another adjacent reinforcing rib, thus forming four triangular inclined surfaces. The surfaces of the first support, the second support, the third support, and the fourth support all have the same threaded structure. By setting up multiple steel trusses with four triangular inclined surfaces, the steel reinforcement assembly is stably stressed, ensuring the stress requirements of the composite slab. The outer side of the support of the steel truss has a threaded structure.

[0004] When the above-mentioned device is in use, it makes the steel reinforcement assembly stable under stress, ensuring the stress requirements of the composite slab. The outer side of the steel truss support has a threaded structure, which increases the stability between the steel reinforcement assembly and the concrete layer. However, when the concrete is poured at the top of the composite slab, the stability of the connection between the composite slab and the concrete after solidification is poor, which makes the bottom of the composite slab prone to deformation. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fireproof composite board. The technical problem to be solved by the present invention is: how to make the connection between the composite board and the poured concrete more stable.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fireproof composite board, comprising an inner layer board, wherein the upper end of the inner layer board is provided with a plurality of mounting protrusions, and the mounting protrusions are provided with a plurality of mounting grooves on the side near the inner layer board, wherein the interior of the mounting grooves is provided with a first reinforcing rib;

[0007] The lower end of the first reinforcing rib is provided with a plurality of second reinforcing ribs, and the lower side of the first reinforcing rib is provided with a supporting reinforcing rib near the outer side of the second reinforcing rib. The lower side of the supporting reinforcing rib is provided with a stable connecting reinforcing rib on the inner side of two adjacent first reinforcing ribs.

[0008] In a preferred embodiment, the lower end face of the inner layer plate is provided with a plurality of protrusions.

[0009] In a preferred embodiment, an outer layer is provided on the outer side of the lower end of the inner layer.

[0010] In a preferred embodiment, the upper end face of the outer layer plate is provided with a plurality of concave grooves.

[0011] In a preferred embodiment, a fixed reinforcing rib is provided on one side of the upper end of the supporting reinforcing rib.

[0012] In a preferred embodiment, the inner layer plate and the mounting protrusion are both made of sulfate as a binder and heat-resistant material as aggregate to form a fire-resistant and heat-resistant concrete, which is called sulfate fire-resistant and heat-resistant concrete.

[0013] In a preferred embodiment, the first reinforcing rib and the stabilizing connecting reinforcing rib have the same cross-sectional diameter, and the cross-sectional diameter of the first reinforcing rib and the stabilizing connecting reinforcing rib is smaller than the cross-sectional diameter of the second reinforcing rib and the fixing reinforcing rib.

[0014] In a preferred embodiment, the supporting reinforcing rib is arranged in a curved state in the main view direction, and the supporting reinforcing rib, the fixing reinforcing rib, the stabilizing connecting reinforcing rib, the first reinforcing rib and the second reinforcing rib are all welded together.

[0015] In a preferred embodiment, a plurality of mounting protrusions and fixing reinforcing ribs are arranged in an array at the upper end of the inner layer plate, the supporting reinforcing ribs are arranged in an inclined state in the right view direction, so that the two supporting reinforcing ribs are arranged in a triangular state in the right view direction, and the inner end face of the mounting groove in the main view direction is larger than the outer end face of the first reinforcing rib in the main view direction.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] In actual use, by setting the first reinforcing rib, the second reinforcing rib and the stable connection reinforcing rib in a corresponding manner, the installation position of the supporting reinforcing rib can be limited by the first reinforcing rib and the second reinforcing rib, thereby supporting the supporting reinforcing rib by the first reinforcing rib and the second reinforcing rib, thus preventing the supporting reinforcing rib from displacing when subjected to large tensile force, and also effectively increasing the strength of the poured concrete, thus improving the stability of the connection between the poured concrete and the inner and outer plates.

[0018] Meanwhile, with the corresponding setting of the concave groove and the protruding block, while ensuring the flatness of the outer layer plate, the inner layer plate can also tighten the outer layer plate, thereby effectively increasing the stability of the inner and outer layer plates during use and preventing deformation of the inner and outer layer plates during use. At the same time, the inner layer plate and the mounting protruding block are made of sulfate-based fireproof and heat-resistant concrete with sulfate as the binder and heat-resistant material as the aggregate, which can effectively increase the high temperature resistance of the inner layer plate during use.

Detailed Implementation

[0025] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0026] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more exemplary embodiments. Numerous specific details are provided in the following description to give a full understanding of exemplary embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, steps, etc., can be employed. In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0027] This utility model provides a fireproof composite board, such as Figure 1 and 2 As shown, it includes an inner layer plate 1. The upper end of the inner layer plate 1 is provided with a plurality of mounting protrusions 3, which can support the inner layer plate 1 and thus ensure the stability of the inner layer plate 1 during use. The mounting protrusions 3 are provided with a plurality of mounting grooves 6 on the side close to the inner layer plate 1.

[0028] The lower end face of the inner layer plate 1 is provided with a plurality of protrusions 5, and the outer layer plate 2 is provided on the outer side of the lower end of the inner layer plate 1. The upper end face of the outer layer plate 2 is provided with a plurality of concave grooves 4. The outer end faces of the plurality of protrusions 5 are adapted to the inner end faces of the plurality of concave grooves 4, which can effectively increase the stability of the connection between the inner layer plate 1 and the outer layer plate 2. While ensuring the flatness of the outer layer plate 2, the inner layer plate 1 can also tighten the outer layer plate 2, thereby effectively increasing the stability of the inner layer plate 1 and the outer layer plate 2 during use and preventing deformation of the inner layer plate 1 and the outer layer plate 2 during use.

[0029] Both the inner layer plate 1 and the mounting protrusion 3 are made of sulfate-based fire-resistant and heat-resistant concrete, which is formulated with sulfate as a binder and heat-resistant material as aggregate. This effectively increases the high-temperature resistance of the inner layer plate 1 during use.

[0030] like Figure 3 , 4 As shown in Figure 5, the interior of the mounting groove 6 is provided with a first reinforcing rib 7, and the lower end of the first reinforcing rib 7 is provided with a plurality of second reinforcing ribs 8. The lower side of the first reinforcing rib 7 is provided with a supporting reinforcing rib 11 near the outer side of the second reinforcing rib 8, which allows the first reinforcing rib 7 to pass through the interior of the mounting groove 6. Thus, the supporting reinforcing rib 11 can be connected to the inner layer plate 1 and the outer layer plate 2 through the first reinforcing rib 7. Therefore, when concrete is poured, the concrete can be integrated into the interior of the mounting groove 6, thereby making the connection between the poured concrete and the inner layer plate 1 and the outer layer plate 2 more stable.

[0031] The supporting reinforcing rib 11 has a stable connecting reinforcing rib 10 on the inner side of two adjacent first reinforcing ribs 7 on its lower side, and a fixing reinforcing rib 9 is provided on one side of the upper end of the supporting reinforcing rib 11. When the first reinforcing ribs 7 and the second reinforcing ribs 8 are in cooperation, the installation position of the supporting reinforcing rib 11 can be limited. When the weight of the poured floor slab is too heavy, the supporting reinforcing rib 11 will be subjected to a large tensile force. The first reinforcing ribs 7 and the second reinforcing ribs 8 will support the supporting reinforcing rib 11, thereby preventing the supporting reinforcing rib 11 from displacing when subjected to a large tensile force.

[0032] The first reinforcing rib 7 and the stable connection reinforcing rib 10 have the same cross-sectional diameter. The cross-sectional diameter of the first reinforcing rib 7 and the stable connection reinforcing rib 10 is smaller than the cross-sectional diameter of the second reinforcing rib 8 and the fixed reinforcing rib 9. The supporting reinforcing rib 11 is set in a curved state in the main view direction.

[0033] The supporting reinforcing rib 11, the fixed reinforcing rib 9, the stabilizing connecting reinforcing rib 10, the first reinforcing rib 7, and the second reinforcing rib 8 are all welded together. The first reinforcing rib 7, the second reinforcing rib 8, the fixed reinforcing rib 9, and the stabilizing connecting reinforcing rib 10 together form a steel truss, which greatly increases the structural strength of the steel truss. This makes the connection between the poured concrete and the inner plate 1 and the outer plate 2 more stable, and increases the contact area between the steel truss and the building concrete, thereby ensuring the strength of the poured concrete after solidification.

[0034] Finally, it should be noted that: the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
