Technical Field

[0001] This utility model relates to the technical field of precast concrete roof panels, specifically a precast concrete roof panel that prevents water leakage at the joints. Background Technology

[0002] Precast concrete roof panels refer to concrete slabs that are prefabricated in a factory and then transported to the construction site for installation. They are widely used in the floor slabs, roof slabs and other parts of buildings, and have many advantages such as faster construction progress, improved production efficiency and lower cost.

[0003] As disclosed in announcement number CN208633345U, a support-free precast concrete roof panel with eaves is comprising a precast eaves panel and a precast roof panel disposed behind the precast eaves panel. The precast eaves panel is connected to the precast roof panel as a whole by eaves connecting steel bars. This utility model integrates the precast roof panel with the eaves, eliminating the need for eaves support during installation, thus improving the installation efficiency of precast components and saving costs. This utility model is applicable to the precasting and installation of precast concrete roof panels in prefabricated buildings.

[0004] However, existing technologies have problems such as water leakage at the joints of precast concrete roof panels during installation, making it inconvenient to drain water in a timely manner, low stability of the joint connection and support, poor shear resistance of precast concrete roof panels, easy surface cracking during long-term use, and need to increase strength. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a precast concrete roof panel that prevents water leakage at the joints. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 .

[0034] To address the problems in existing technologies, such as water leakage at the joints of precast concrete roof panels during installation, difficulty in timely drainage, low stability of joint connections and supports, poor shear resistance, easy surface cracking during long-term use, and the need to increase strength, this solution provides a precast concrete roof panel that prevents water leakage at joints. The panel comprises a concrete roof panel body 1 and integrally formed concrete side columns 2 on the lower left and right sides of the concrete roof panel body 1. Support members 4 are located below the concrete roof panel body 1 at the left and right ends, with a drainage groove 7 in the middle of the support member 4.

[0035] like Figure 1 and Figure 3As shown, the concrete roof panel body 1 is composed of a concrete main body 101, reinforcing steel ribs 102, wire mesh 103 symmetrically arranged at the upper and lower ends of the concrete main body 101, and a mortar leveling layer 104 set on the outside of the concrete main body 101. The concrete main body 101 and reinforcing steel ribs 102 are cast in a mold, and wire mesh 103 is set at both the upper and lower ends of the concrete main body 101. During casting, the wire mesh 103 is located at the upper and lower ends. The setting of the wire mesh 103 can improve the overall shear resistance of the concrete roof panel body 1 and effectively prevent surface cracking during long-term use. The mortar leveling layer 104 is set on the outer surface of the concrete main body 101, which can improve the flatness of the outer surface of the concrete roof panel body 1.

[0036] When splicing, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the support member 4 is fixed to the external support frame. Side support columns 5 are integrally formed on the left and right sides of the upper end of the support member 4, and fixing grooves 6 are evenly spaced on the side of the side support columns 5. The fixing grooves 6 are correspondingly set with the positioning blocks 3 on the side of the concrete side column 2. The concrete roof panel body 1 and the concrete side column 2 drive the positioning blocks 3 to engage in the corresponding fixing grooves 6, thereby facilitating the installation and positioning of the concrete roof panel body 1 and the support member 4. Then, the side support columns 5 and the concrete side columns 2 are connected and limited by the fastening bolts 10. Meanwhile, the concrete roof panel body 1 at the connected position is set in close contact, and drainage holes 8 are opened on both the left and right sides of the concrete roof panel body 1. A drainage groove 7 is opened in the middle of the support member 4. When water enters the drainage groove 7 through the drainage holes 8, the concrete roof panel body 1 and the support member 4 can be tilted during the actual installation process. The water is discharged out in time through the drainage groove 7, which can effectively prevent water leakage at the joint of the concrete roof panel body 1. In addition, the lower end of the concrete roof panel body 1 is equipped with an insulation board 9, which can play a good role in heat preservation.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
