Description

Technical Field

[0001] This utility model relates to the field of prefabricated floor slab technology, specifically a prefabricated fireproof and corrosion-resistant floor slab structure for building engineering. Background Technology

[0002] Prefabricated floor slabs are floor slabs that are prefabricated in a factory and then transported to the construction site for installation. These floor slabs are usually made of materials such as concrete and steel bars, and have the characteristics of standardization and modularization. On-site installation is all that is required, which greatly shortens the construction cycle.

[0003] For example, Chinese patent CN202390977U (Prefabricated Floor Slab) includes a concrete slab with a plurality of first reinforcing bars spaced apart along its length. Each first reinforcing bar passes vertically through the lower left or right side of the concrete slab, and its two ends are inserted into the concrete slab along the upper left or right side, respectively. A plurality of second reinforcing bars are also spaced apart along the width of the concrete slab. Each second reinforcing bar passes vertically through the lower front or rear side of the concrete slab, and its two ends are inserted into the concrete slab along the upper front or rear side, respectively. This prefabricated floor slab has low cost, shortens the overall construction time, and improves work efficiency.

[0004] However, most existing prefabricated floor slabs are assembled by aligning the edges and surfaces, which can easily lead to misalignment and water ingress at the joints. This makes the slabs prone to corrosion and reduces their service life. Therefore, this does not meet the current requirements. To address this, we propose a prefabricated fireproof and corrosion-resistant floor slab structure for building engineering. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated fireproof and corrosion-resistant floor slab structure for building engineering, in order to solve the problems mentioned in the background art that most existing prefabricated floor slabs are assembled by aligning the edge surfaces, which makes the joints prone to positional misalignment and deviation, water ingress at the joints, and difficulty in quick cleaning, resulting in easy corrosion and short service life of the floor slabs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated fireproof and corrosion-resistant floor slab structure for building engineering, comprising: a floor slab, wherein a stable steel reinforcement frame is provided at the upper end of the floor slab, and multiple stable steel reinforcement frames are provided; an assembly connection plate is provided on one side surface of the top of the floor slab, and an assembly connection groove is provided on the other side surface of the top of the floor slab, and multiple assembly connection plates and assembly connection grooves are provided.

[0007] Preferably, a waterproof membrane is provided at the upper end of the assembly connection groove, and after the assembly connection plate is connected to the assembly connection groove, the waterproof membrane is fixed to the floor slab and the assembly connection plate by the self-adhesive surface.

[0008] Preferably, the floor slab includes a substrate and a flame-retardant coating, and the flame-retardant coating is uniformly applied to the outer surface of the substrate. An anti-corrosion layer is uniformly applied to the outer surface of the flame-retardant coating, and a surface coating is uniformly applied to the outer surface of the anti-corrosion layer. The anti-corrosion layer is made of epoxy resin, and the surface coating is made of fluorocarbon coating.

[0009] Preferably, the floor slab further includes vertical reinforcing bars, which are inserted into the interior of the substrate, and multiple vertical reinforcing bars are provided.

[0010] Preferably, the stabilizing steel reinforcement frame includes a first steel reinforcement bar and a second steel reinforcement bar, a third steel reinforcement bar is provided above the first steel reinforcement bar and the second steel reinforcement bar, and the lower surfaces of the first steel reinforcement bar and the second steel reinforcement bar are welded and fixed to the top of the vertical steel reinforcement bar.

[0011] Preferably, reinforcing bars are welded between the first and second reinforcing bars and the third reinforcing bar, and multiple reinforcing bars are provided. Connecting bars are welded to the lower surface of the third reinforcing bar, and multiple connecting bars are provided.

[0012] Preferably, the lower surface of the floor slab is provided with a stabilizing groove, and multiple stabilizing grooves are provided.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets assembly connecting plates and assembly connecting grooves on both sides of the floor slab. When multiple floor slabs are assembled, the assembly connecting plate of one floor slab is inserted into the assembly connecting groove of another floor slab, which has a limiting effect and increases the contact area. This improves the stability of the assembly connection of multiple floor slabs, makes it less likely to shift position, ensures the neatness between multiple floor slabs, and also improves the sealing of the connection. In addition, the waterproof membrane is fixed to the floor slab and the assembly connecting plate through the self-adhesive surface, which has a waterproof effect on the connection of multiple floor slabs, avoids water ingress and causes corrosion and damage to the floor slab, and improves the service life. This solves the problem that most existing prefabricated floor slabs are assembled by aligning the edge surfaces, which makes the connection easy to shift position, cause deviation, and allow water to enter the connection, which is not easy to clean quickly, resulting in easy corrosion of the floor slab and a short service life.

[0015] (2) By sequentially applying flame-retardant coating, anti-corrosion layer and surface coating to the outer surface of the substrate, the anti-corrosion layer is made of epoxy resin, which has excellent adhesion and chemical resistance, and can effectively resist acid and alkali corrosion. The surface coating is made of fluorocarbon coating, which has extremely high weather resistance and chemical corrosion resistance, improving the fire and corrosion resistance of the substrate, making it less prone to damage and increasing its service life. It is used in conjunction with the sealing of the connection between multiple floor slabs, further improving the fire and corrosion resistance of the floor slab. Attached Figure Description
