Description

Technical Field

[0001] The utility model relates to the technical field of construction, and more specifically, to a prefabricated double T-plate. Background Art

[0002] The double T-slab is a prefabricated reinforced concrete load-bearing member combining a slab and a beam. It consists of a wide panel and two narrow and high ribs. The panel is both a transverse load-bearing structure and a compression zone for the longitudinal load-bearing ribs.

[0003] Existing double T-boards are generally used in the roofs of high-rise buildings or factories. Multiple double T-boards are arranged to form a complete ceiling surface. However, there will be joints at the joints of two adjacent double T-boards. Rainwater will penetrate into the joints, causing mold to grow and rot, thereby affecting the strength of the double T-boards.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0007] The utility model is further configured as follows: the width of the convex edge is smaller than the width of the groove; the waterproof plate comprises an inserting portion and a blocking portion; the inserting portion is used for inserting between the convex edge and the groove.

[0008] The utility model is further configured as follows: an embedding groove is arranged on the panel, and folding edges for embedding into the embedding groove are arranged on both sides of the waterproof plate.

[0009] The utility model is further configured as follows: the panel is provided with through holes penetrating the panel along the length direction, and a steel bar skeleton is provided inside the panel.

[0010] The utility model is further configured as follows: the diameter of the through hole is 1 / 2 of the thickness of the panel, and the distance between two adjacent through holes is greater than 1 / 4 of the width of the panel.

[0011] The utility model is further configured as follows: a part of the steel bar skeleton extends downward to form a rib skeleton, and the rib skeleton is located inside the ribs.

[0012] The utility model is further configured as follows: the distance between the two ribs is greater than 1 / 2 of the width of the panel and less than 2 / 3 of the width of the panel.

[0013] The utility model is further configured as follows: the length of the rib is less than 1 / 2 of the width of the panel.

[0014] In summary, the utility model has the following beneficial effects:

[0015] By setting a waterproof board at the connection of the two double T-boards, rainwater cannot penetrate into the connection through the joints, so that the double T-board has a certain waterproof ability, thereby keeping the connection of the two double T-boards in a dry state, limiting the occurrence of mold-induced cement corrosion to a certain extent, and making the double T-board have a longer service life.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Prefabricated double T-plate, such as Figure 1 As shown, it includes a panel 1 and two ribs 2 fixedly connected to the panel 1, the ribs 2 are used to support the panel 1, and the panel 1 and the ribs 2 constitute the basic structure of a double T-board, which is used to make the roof of a high-rise house or factory building. The length of the rib 2 is less than 1 / 2 of the width of the panel 1. The shorter ribs 2 can concentrate most of the pressure received near the panel 1, and the panel 1 itself has strong compressive resistance and high strength, so it can be used to ensure that the ribs 2 will not break, thereby ensuring the normal use of the double T-board.

[0022] like Figures 1 to 3As shown, the panel 1 is provided with a through hole 14 penetrating the panel along the length direction. The through hole 14 can form a cavity in the panel 1, which saves the amount of cement mortar required for the panel 1 while ensuring the strength of the panel 1, thereby saving materials. A steel skeleton 15 is provided in the panel 1. The steel skeleton 15 enables the panel 1 to form a reinforced concrete structure, further improving the strength of the panel 1, making the double T-plate have a stronger pressure-bearing capacity, and further ensuring the normal use of the double T-plate.

[0023] like Figure 1 and Figure 2 As shown, the diameter of the through hole 14 is 1 / 2 of the thickness of the panel 1, and the distance between two adjacent through holes 14 is greater than 1 / 4 of the width of the panel 1. This arrangement allows the through holes 14 to have a reasonable density, thereby ensuring that the panel 1 still has a high strength.

[0024] like Figure 3 As shown, the steel frame 15 extends downward to form a rib frame 16, and the rib frame 16 is located in the rib 2. The rib 2 is also implanted with a frame, so that the structural strength of the rib 2 is further improved, thereby improving the load-bearing capacity of the double T-board and making the roof have a longer service life.

[0025] like Figure 1 and Figure 2 As shown, the two sides of the panel 1 are respectively provided with a convex edge 11 and a groove 12 for clamping two adjacent panels 1. The convex edge 11 and the groove 12 can be used to increase the contact area between the two panels 1, thereby extending the path required for moisture to penetrate into the joint, which can play a waterproof role to a certain extent, thereby preventing the joints of the two panels 1 from rotting and causing the concrete strength to decrease, ensuring the normal use of the double T-board, and a waterproof board 3 is provided at the connection between the convex edge 11 and the groove 12. The waterproof board 3 can be used to further ensure that moisture is not easy to penetrate into the joint, thereby strengthening the waterproof ability of the panel 1.

[0026] The width of the convex edge 11 is smaller than the width of the groove 12. This arrangement allows a larger gap to be formed between the two panels 1 for inserting the waterproof board 3. The waterproof board 3 includes an inserting portion 31 and a blocking portion 32. The inserting portion 31 is used to be inserted between the convex edge 11 and the groove 12. When the inserting portion 31 is inserted into the joint, the blocking portion 32 can further block external moisture, further extend the path for water to penetrate between the panels 1, further enhance the waterproof ability between the panels 1, and ensure the normal use of the double T-board.

[0027] The panel 1 is provided with an embedding groove 13, and the waterproof board is provided with folding edges 33 on both sides for embedding into the embedding groove 13. The embedding groove 13 and the folding edges 33 can further enhance the waterproof ability of the waterproof board 3, making it more difficult for moisture to penetrate into the joints.

[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
