The construction method has the advantages that the operation work is diversified, the construction process is complicated, the construction cost is continuously increased under the condition that the current construction workers are basically in the demander market, the site waste and the garbage are more, and the construction progress and the quality safety are directly influenced. Because of the objective existence of the construction process, a plurality of construction intermittences occur, normal running construction cannot be formed, various workers, particularly a steel bar worker, a template worker and a concrete worker cannot be intensively and compactly constructed, and even the wall body building construction is carried out before the initial setting of the concrete strength, so that the horizontal member of the secondary structure is seriously damaged. Even if a general assembly type wall body is adopted for construction, the edge reinforcing structure requirements of positions such as door and window openings and the like are difficult to meet (unless construction reinforcing measures are additionally designed), and the subsequent problems of wall body cracks, unreliable door and window fixing and the like can occur. How to find or invent a construction method which is convenient to operate, accelerates progress, reduces cost, ensures quality and safety, saves energy and protects environment is a goal pursued by all people in the field of buildings.

Detailed Description

As shown in fig. 1, 2, 3 and 4, the lintel cement formwork 1 is designed and factory-made, and should meet the following requirements: the wall thickness of the cement template is 15mm, the concrete strength grade is not lower than C25, and the size deviation of the template is +/-1 mm; the lintel cement formwork 1 should have cement dowels 3 (threaded steel bars). The lintel cement formwork 1 is of a strip-type groove structure, and one row or two rows of cement pins 3 are axially fixed in the groove of the lintel cement formwork 1.

The independent construction of the lintel is generally divided into three cases, one is that both ends of the lintel are placed on the masonry 9, the other is that one end is placed on the masonry 9 and the other end is placed on the vertical concrete member, and the other is that both ends are placed on the vertical concrete member. The second case with greater difficulty in operation will be described below.

When the filler wall is constructed to the elevation of a beam bottom (including the beam bottom), considering that the length of a placed wall body of a lintel is not less than 240mm, firstly, a bonded lintel cement template 1 is built on the upper surfaces of brickworks 9 on two sides of the edge of a door and window opening, and the length of the placed wall body is determined on site according to the design width of the door and window opening and the splicing modulus of the lintel cement template on the premise of meeting the requirement of not less than 240mm, wherein the placed length can be a little larger, and the cutting of the cement template is avoided as much as possible.

After two lintel cement formworks at the edge of the door and window opening are installed, a lintel reinforcement cage formed by combining a lintel stress steel hoop 5 and a lintel stirrup 4 is installed, one end of the lintel reinforcement cage is firmly connected with installation steel bars of vertical concrete members or post-planted anchoring steel bars, the other end of the lintel reinforcement cage is placed on the lintel cement formwork 1 at the edge of the door and window opening, and the lintel reinforcement cage is in a suspended state. Then, binding and connecting iron wires 6 on cement pins 3 (threaded steel bars) of the lintel cement template 1 which is installed subsequently in advance, hoisting the lintel cement template 1 to the suspended position of the lintel reinforcement cage, and firmly connecting the lintel cement template with the lintel reinforcement cage through the connecting iron wires 6.

Then arranging a temporary support 10 under the lintel, wherein the temporary support 10 adopts a steel top column with higher rigidity, the top of the temporary support is matched with an inserted adjustable steel top support, 50 x 70 support square timbers 7 are additionally arranged in a U-shaped groove at the top end of the steel top support, the bottom of the subsequently installed lintel cement template is flat by adjusting the height of the steel top support, and then polymer cement mortar or common cement mortar is adopted to bond and block template splicing gaps at the bottom and two side faces of the subsequently installed lintel cement template. After the lintel formwork and the steel bars are installed, concrete is poured in time, and the number of horizontal members of the secondary structure synchronously poured with the lintel concrete is planned on site.
