[0025] To make the above-mentioned objects, features, and advantages of the present invention more readily understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] The utility model discloses a prefabricated device for preventing leakage of an L-shaped pressure top beam for building an external window sill, comprising: a side panel 1, two side panels 1 being symmetrically provided, a step being formed on the top surface of the side panel 1, a first top surface 10 of the step being higher than a second top surface 11, and the first top surface 10 and the second top surface 11 being connected via a connecting surface 14 extending upward;
[0027] The front end surfaces 12 of the two side panels 1 are fixedly connected to the first top panel 2 , the rear end surfaces 13 of the two side panels 1 are fixedly connected to the second top panel 3 , and the connecting surfaces 14 of the two side panels 1 are fixedly connected to the third top panel 6 ;
[0028] A first wooden square 4 is provided on the outer side of the second top plate 3, a second wooden square 5 is provided on the outer side of the first top plate 2, and a third wooden square 7 is provided on the outer side of the third top plate 6;
[0029] The first wooden square 4 and the third wooden square 7 are clamped on the second top plate 3 and the third top plate 6 by the first U-shaped fixing piece 8, and the first wooden square 4 and the second wooden square 5 are clamped on the first top plate 2 and the second top plate 3 by the second U-shaped fixing piece 80.
[0030] It should be noted that the first U-shaped fixing member 8 and the second U-shaped fixing member 80 are wooden boards cut into a U shape. Furthermore, the first top panel 2, the second top panel 3, and the third top panel 6 are fixedly connected to the two side panels 1 by nails. The front end 12, the rear end 13, and the connecting surface 14 of the side panels 1 are all provided with positioning holes (not shown in the drawings) for inserting nails to prevent the nails from being driven into the edge of the wood.
[0031] Specifically, combined Figure 2 As shown, the connecting surface 14 is a vertical surface, and the heights of the third top plate 6 and the third wooden square 7 are equal to or lower than the height of the first top surface 10, so that the first U-shaped fixing member 8 and the second U-shaped fixing member 80 can better fit with the lower member to improve firmness;
[0032] Combine Figure 1 As shown, two first U-shaped fixing members 8 are provided and are symmetrically arranged, and two second U-shaped fixing members 80 are provided and are symmetrically arranged.
[0033] Specifically, the thickness of the second wooden square 5 is greater than the thickness of the first top plate 2, the thickness of the first wooden square 4 is greater than the thickness of the second top plate 3, and the thickness of the third wooden square 7 is greater than the thickness of the third top plate 6. The first, second and third wooden squares are used for reinforcement, and increasing their thickness is conducive to improving the overall connection strength, so that the first U-shaped fixing piece 8 and the second U-shaped fixing piece 80 are clamped more tightly to avoid loosening caused by vibration.
[0034] Furthermore, an oily demoulding layer is provided around the space enclosed by the two side panels 1, the first top panel 2, the second top panel 3 and the third top panel 6, so as to facilitate demoulding of the L-shaped top beam and manufacture the formed L-shaped top beam 91. Figure 3 shown.
[0035] During production, the side panels 1, the first top panel 2, the second top panel 3, the third top panel 6, the first wooden square 4, the second wooden square 5, the third wooden square 7, the first U-shaped fixing member 8 and the second U-shaped fixing member 80 are positioned, laid out, cut and punched according to the drawings. The materials used are wood boards and wooden squares. Figure 2 As shown, after the production is completed, the component is surrounded by a first opening 9 and a second opening 90, through which pouring, injection and vibration are carried out. The opening located below the first opening 9 and the second opening 90 is the demoulding opening of the L-shaped pressure beam 91.
[0036] In summary, the device is easy to manufacture, requiring only wooden boards, wooden planks and nails. It can be further reinforced by setting U-shaped fixings and wooden planks before pouring. At the same time, the disassembly and demoulding of the device are also very convenient and quick. The device can be used multiple times, reducing the cost and workload of prefabricated formwork for pouring the L-shaped pressure beam, and is also convenient for vibration during the pouring process.
[0037] The embodiments described above merely represent one or more implementations of the present invention. While their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
