[0026] Referring to Figure 2 , the building door and window lintel of the present application mainly comprises four parts of a support beam 2, a tension conversion table 3, a stress reinforcement 4 and a block 5, wherein the support beam 2 is a relatively thin concrete flat plate, for a door and window opening not more than 1.2 meters wide, the thickness of the support beam 2 can be manufactured to be 4 centimeters. The tension conversion table 3 is also made of a concrete block, the tension conversion table 3 is fixedly installed at both ends of the support beam 2, and the tension conversion table 3 and the support beam 2 are integrally formed and cast.
[0027] Further, in combination with Figure 1 and Figure 2As shown, the bottom of the tension conversion table 3 and the bottom of the support beam 2 are flush, and the height of the tension conversion table 3 in this embodiment is 15 cm. The space for installing the mounting block 5 is surrounded by the middle of the two tension conversion tables 3 and above the support beam 2. Eight mounting blocks 5 (for example, bricks) are installed in a neat manner on the top of the support beam 2, and the left mounting block 5 abuts against the left tension conversion table 3, and the right mounting block 5 abuts against the right tension conversion table 3.
[0028] It should be noted that the height of the mounting block 5 is 11.5 cm, and the top surface of the mounting block 5 is flush with the top surface of the tension conversion table 3. Before installing the mounting block 5, cement is applied to the surface of the mounting block 5, which is beneficial to forming an integral body with the tension conversion table 3 and the support beam 2 after solidification, thereby meeting the force requirement.
[0029] In some embodiments of this embodiment, in order to make the strength of the building door and window lintel meet the force requirement, a force bearing steel bar 4 is installed inside the support beam 2, which is combined with the Figure 1 As shown, the two ends of the force bearing steel bar 4 are connected with an extension part one 401, and the end of the extension part one 401 is connected with an extension part two 402. The force bearing steel bar 4 is horizontally installed inside the support beam 2, and the extension part one 401 is vertically installed upwards inside the tension conversion table 3. Since the bottom end of the extension part one 401 is fixedly connected with the right end of the force bearing steel bar 4, the extension part one 401 and the force bearing steel bar 4 are perpendicular to each other.
[0030] Further, in combination with Figure 2 As shown, in order to make the tension conversion table 3 play a better force bearing effect, the top end of the extension part one 401 is connected with the extension part two 402, the left extension part two 402 extends towards the lower left, and the right extension part two 402 extends towards the lower right, and the extension part one 401 and the extension part two 402 form a V shape. The force bearing steel bar 4, the extension part one 401 and the extension part two 402 can all be made of screw steel.
[0031] It should be noted that in combination with Figure 1 As shown, the width occupied by the extension part one 401 and the extension part two 402 is not less than two-thirds of the width of the tension conversion table 3, for example, the width of the tension conversion table 3 is 50 cm, and the width of the extension part one 401 and the extension part two 402 is 35 cm.

[0035] Support beam 2 (including tension conversion platform 3) can adopt reinforced concrete prefabrication, and stress reinforcement 4 is arranged in the inside of support beam 2 (tension conversion platform 3), so that the overall strength of the door and window lintel of the building is increased. When installation, workers only need to install support beam 2 and tension conversion platform 3 to the top of door hole wall body 1 first, and then install block 5 on support beam 2. The weight of support beam 2 and tension conversion platform 3 is far lower than that of the traditional concrete prefabricated beam, and the weight of block 5 is also low, so it is easier for workers to lift and install, and it is also easier to install. It is not easy to fall accidentally, and the safety of workers is better.
[0036] Suppose the size of the lintel is: 200mm high * 200mm wide * (900mm door hole width + 300mm * 2)
[0037] The weight of the conventional lintel is: 0.2m * 0.2m * 1.5m * ρ density (2.5 * 10 3 kg / m 3 ) ≈ 150kg
[0038] The weight of the door and window lintel of the building of the utility model: 0.2m * 0.04m * 1.5m * ρ density (2.5 * 10 3 kg / m 3 ) ≈ 30kg
[0039] The height of the door hole is generally 2.1m, and at least 3 people are needed to place the conventional lintel to the specified position. The weight of the door and window lintel of the building of the utility model is smaller, and only one person is needed to place it to the specified position. The door and window lintel of the building of the utility model has positive significance for improving the efficiency and progress of the construction site.
[0040] Combining Figure 1 The stress analysis shows that support beam 2 is a tensile region, block 5 is a compression region, and tension conversion platform 3 is a tensile and compressive stress conversion region, that is, the forces borne by the tensile region and the compression region are equal in size and opposite in direction.
