Autoclaved aerated block lintel and construction method thereof

Abstract

The invention discloses an autoclaved aerated block lintel and a construction method thereof. The construction method comprises the steps that first pre-buried components are arranged on vertical main structures on the two sides of a lintel; second pre-buried components are arranged at the bottom of a horizontal main structure on the top of the lintel; a lintel bottom bracing is fixedly mounted between the first pre-buried components arranged on the vertical main structures on the two sides of the lintel; lintel vertical bracings are fixedly mounted between the second pre-buried components and the lintel bottom bracing; the outer side of the lintel bottom bracing and the outer sides of the lintel vertical bracings are cladded by an autoclaved aerated masonry shell to form lintel bottom bracing casting space and lintel vertical bracing casting space which internally communicate with each other; concrete casting is conducted in the lintel bottom bracing casting space and the lintel vertical bracing casting space to form a lintel combination bracing; and autoclaved aerated blocks are constructed on the lintel combination bracing, and lintel construction is completed. The autoclaved aerated block lintel and the construction method thereof are applied to the construction method of an autoclaved aerated block large-span hole lintel, and have the characteristics of convenient construction and little size deviation compared with a traditional cast-in-place concrete lintel, formwork erection is omitted, and the appearance quality is improved.

Description

technical field [0001] The invention relates to the technical field of energy-saving buildings, in particular to an autoclaved aerated block lintel and a construction method thereof. Background technique [0002] In the field of energy-saving building technology, lightweight cement-based blocks, such as autoclaved aerated concrete blocks and foam concrete blocks, are widely used for walls of enclosure structures. The top of the opening in the wall is the door and window lintel. The use of the door and window lintel is in two basic states. One is that both ends are symmetrically lapped on the vertical wall of the hole, and the other is that only one end is lapped on the vertical wall of the hole. , and the other end is butted on the construction column. The prefabricated cement lintel or steel structure lintel welded with the embedded iron parts on the side of the structural column has high cost and forms a large thermal bridge; In addition to the high cost and the existenc...

Problems solved by technology

However, because the autoclaved aerated concrete block is a porous autoclaved product, it has defects such as low strength and elastic modulus, and large size deviation.

The current autoclaved aerated concrete block masonry filling wall is generally built on a pre-cast concrete square frame (concrete square frame composed of vertically arranged left and right columns, horizontally arranged top beams and bottom beams) In the interior, the autoclaved aerated concrete blocks are stacked horizontally and the vertical joints are staggered to build them in the concrete square frame with mortar. When painting, add anti-crack agent or anti-crack to the inner and outer walls. Fiber anti-cracking mortar, autoclaved aerated concrete block masonry filling wall using the above technology can solve the problems of weak strength and large size deviation to a certain extent, but it is troublesome to operate, low in efficiency and high in cost
