specific Embodiment
[0023] The specific embodiment is illustrated in conjunction with the accompanying drawings: a door and window lintel, the walls 1 on both sides of the door and window are built with reinforced wall panels 2, the thickness of the reinforced wall panels 2 is 15 cm, and the appearance of the reinforced wall panels It is in the shape of a long strip, with a cross-section approximately rectangular, with mortise and tenon structures on both sides, reinforcing ribs inside, and a plurality of through holes 3 along the length direction of the board body. The reinforced wall panel 2 on both sides of the door and window is a whole piece from the ground to the upper end of the wall, and the wall 1 is cut above the door and window into a rectangle with a width of 30 cm and a height up to the top, forming a supportable lintel The supporting platform 5 of 6, its longitudinal cutting position is to cut along the middle of a through hole 4 or blind hole 4; The lintel 6 is also formed by cuttin...

The invention provides a door window lintel. Wall bodies on two sides of a door window are built from reinforced wall boards, a supporting platform capable of supporting a lintel is cut on the wall bodies above the door window, and a through hole cut along the middle is arranged at each end of the supporting platform; the lintel is formed of reinforced wall boards by cutting, and after the lintel is placed on the supporting platform, the through holes of the lintel are in horizontal direction; a gap is formed between the end of the lintel and each through hole cut along the middle; the horizontal through holes of the lintel are plugged off to form horizontal cylindrical holes; each through hole cut from the middle is plugged off below the supporting platform to form a vertical cylindrical hole; and when the lintel 6 is mounted, concrete is densely poured into all the spaces among the above horizontal cylindrical holes, the vertical cylindrical holes and the gaps in one time. The door window lintel provided by the invention can achieve the following technical effects: large span, short construction period, simple maintenance, low technical difficulties, saved material and good overall performance. The door window lintel is suitable for generalization and use.
Description
technical field [0001] The invention relates to a lintel for door and window openings. Background technique [0002] Traditional lintels include brick arch lintels, ribbed brick lintels, and reinforced concrete lintels. [0003] The disadvantages of brick arch lintels are that the construction speed is slow, the span is small, and it is not suitable for use with concentrated loads or half-brick walls. The construction of the reinforced brick lintel is troublesome, the span should not be too large, and the amount of steel and cement is large, and the wall needs to be continued on the lintel. Reinforced concrete lintels use more steel bars and cement. Among them, the cast-in-place reinforced concrete lintel has a long construction period, masonry maintenance is troublesome, and it is easy to crack, which creates psychological fear for users and poses a potential threat to future safety. Using prefabricated reinforced concrete lintels can increase the construction speed and ...
