Abstract

The invention belongs to the technical field of building construction, and relates to a molding method of a window opening. A beam bottom molding plate is braced on the bottom of a structural beam firstly, a first batten is additionally arranged on the inner side of the beam bottom molding plate corresponding to a window, beam side molding plates are symmetrically braced on the two sides of the structural beam, sill lintel side molding plates are symmetrically braced on the two sides of a sill lintel, a second batten is fixedly braced at a window bottom outer port, the window opening is pouring-molded along with a concrete structure, after the concrete structure is poured, a braced window top opening molding plate and a window bottom opening molding plate are disassembled, an opening which is increased in height from outside to inside and comprises an eagle beak is formed in the upper port of a window cavity, and the opening which is increased in height from outside to inside and comprises a water slope is formed in a lower port of the window cavity, so that the once molding of the window opening is achieved. The molding method is simple in method, convenient to operate, high in production efficiency, low in cost, and capable of effectively solving the window leakage problem and can be widely applied to the molding processes of the window openings during building construction.

Description

The forming method that a kind of window is begun to speak

Technical field:

The invention belongs to technical field of building construction, relate to a kind of window and begin to speak and build one-time formed construction technology with the concrete structure, particularly a kind of window forming method of beginning to speak.

Background technology:

Along with improving constantly with various advanced persons' construction technology of building operations level constantly emerged in large numbers, the building operations quality has had qualitative leap, but the window seepage situation in the present building after its design and the construction is more, and has become one of each department qualitative factor.Existing technology is generally all continued to use by interior plastering and is formed the mode of beginning to speak in the window in window each construction enterprises that begin to speak aspect the way of node, administer this common quality defect of window seepage, in this method depth of plastering thicker (at present thin plaster popular, this technology is not suitable for the window place and plasters), layering float work inefficiency, the easy crack of interior window, in begin to speak and plaster and begin to speak insulation joint part leakiness outward, thereby cause the window seepage, especially high residential building engineering also exists maintenance difficult, operating expenses height when this defective occurring, so the demand of the window place of beginning to speak in the existing building construction being improved job practices is very urgent.

Summary of the invention:

The objective of the invention is to overcome the shortcoming that prior art exists, seek to design the job practices that provides a kind of window to begin to speak disposal molding, adopt one-time formed construction technology to solve the window leakage problems, the secondary frame of cancellation window, accelerate speed of application, enhance productivity, reduce cost, constructing operation is convenient.

To achieve these goals, the present invention realizes that the begin to speak concrete processing step of moulding of window is:

(1), the window top formwork erection of beginning to speak: install the beam bottom board plate in the bottom of structural beams earlier, the inboard corresponding window of beam bottom board plate place sets up first flitch, and the size of first flitch is definite according to the thickness of outer window; Bilateral symmetry in structural beams installs side template again, and the height of side template is higher than the structure depth of beam, exceeds the width that is of a size of first flitch;

(2), the window bottom formwork erection of beginning to speak: window is built outside the windowsill lintel, install windowsill in the bilateral symmetry of windowsill lintel and cross side template, the collar extension place fixedly installs second flitch at the bottom of window, and second flitch is fixed on the inboard of crossing side template with the windowsill of collar extension homonymy at the bottom of the window;

(3), the window moulding of beginning to speak: window is begun to speak and is built moulding with concrete structure, after the concrete structure casting, remove window top that step (1) and (2) installs the respectively template of beginning to speak bottom template and the window of beginning to speak, the outer low and inner high band olecranon of interruption-forming begins to speak on window opening, the outer low and inner high band flowing water of the interruption-forming gradient begins to speak the one-shot forming that the realization window is begun to speak under the window opening.

The present invention compared with prior art, its method is simple, and is easy to operate, the production efficiency height, cost is low, effectively solves the window leakage problems, can be widely used in the forming process that window is begun to speak in the building operations.

Description of drawings:

Fig. 1 is the window top that the present invention relates to formwork erection structural principle schematic diagram of beginning to speak, and comprises structural beams 1, side template 2, first flitch 3 and beam bottom board plate 4.

Fig. 2 is the window bottom that the present invention relates to formwork erection structural principle schematic diagram of beginning to speak, and comprises that windowsill lintel 5, windowsill cross side template 6 and second flitch 7.

Fig. 3 is the exterior window that the present invention relates to molding structure principle schematic of beginning to speak, and comprises that plastering on inner walls 8, external wall insulation 9, exterior wall bonding powder granule finish coat 10, exterior window play glue 11 and exterior window foaming 12.

The specific embodiment:

Also the invention will be further described by reference to the accompanying drawings below by embodiment.

Embodiment:

Present embodiment realizes that the begin to speak concrete technology of disposal molding of window comprises window top formwork erection, window bottom formwork erection and window three steps of moulding of beginning to speak of beginning to speak of beginning to speak:

(1), the window top formwork erection of beginning to speak: install beam bottom board plate 4 in the bottom of structural beams 1 earlier, it is definite according to the thickness of outer window that beam bottom board plate 4 inboard corresponding window places set up the size of first flitch, 3, the first flitches 3; Bilateral symmetry in structural beams 1 installs side template 2 again, and the height of side template 2 is higher than the height of structural beams 1, exceeds the width that is of a size of first flitch 3;

(2), the window bottom formwork erection of beginning to speak: window is built outside windowsill lintel 5, install windowsill in the bilateral symmetry of windowsill lintel 5 and cross side template 6, the collar extension place fixedly installs second flitch, 7, the second flitches 7 and is fixed on the inboard of crossing side template 6 with the windowsill of collar extension homonymy at the bottom of the window at the bottom of window;

(3), the window moulding of beginning to speak: window is begun to speak and is built moulding with concrete structure, after the concrete structure casting, remove window top that step (1) and (2) installs the respectively template of beginning to speak bottom template and the window of beginning to speak, the outer low and inner high band olecranon of interruption-forming begins to speak on window opening, the outer low and inner high band flowing water of the interruption-forming gradient begins to speak the one-shot forming that the realization window is begun to speak under the window opening.

Claims (1)

1. forming method that window is begun to speak is characterized in that realizing that the begin to speak concrete processing step of moulding of window is:

(1), the window top formwork erection of beginning to speak: install the beam bottom board plate in the bottom of structural beams earlier, the inboard corresponding window of beam bottom board plate place sets up first flitch, and the size of first flitch is definite according to the thickness of outer window; Bilateral symmetry in structural beams installs side template again, and the height of side template is higher than the structure depth of beam, exceeds the width that is of a size of first flitch;
