1 Scope
The process standards applicable to general construction and high-level construction projects, windowsill, heating cover the installation works.
2 construction preparation
2.1 Materials and construction parts:
2.1.1 different materials produced by the windowsill generally have the following: wooden windowsill board, cement sill plate, terrazzo sill plate, natural stone window sills and metal windowsill board.
2.1.2 windowsill plate, heating hood production of materials, materials, colors should be selected according to the design, wood products should be drying, control moisture content of less than 12%, and do a good job preservative treatment, does not allow distortion.
2.1.3 installation fixed general use angle or flat steel bracket or rack; window plate structure generally installed directly under the window wall to be mortar or fine stone concrete solid.
2.2 The main equipment:
2.2.1 electric equipment: electric welding machine, electric saw stone machine, hand drill.
2.2.2 hand tools: large plane, small plane, small saw, hammer, cut corner, rubber hammer, by foot board, 20 wire and small wire, iron level foot, box foot, screwdriver.
2.3 Operating conditions:
2.3.1 installation of the sill under the window of the window, in the construction of the structure should be based on the choice of sill plate varieties, embedded wood bricks or iron pieces.
2.3.2 When the length of window sill is more than 1500mm, in addition to wooden bricks or iron pieces at both ends of the window, the middle should be made of water brick or iron piece every 500mm. The bracket should be fixed according to the design requirements.
2.3.3 install the sill board, heating hood should be installed after the window frame. Windows and heating panels cover piece, should be in the wall, after the completion of the ground decoration layer.
3 operating process
3.1 Process flow:
Positioning and crossed → Check the embedded parts → bracket installation → installation of the heating plate → window heating
3.2 positioning and marking: According to the design requirements of the window frame under the frame elevation, position, draw the sill plate elevation, position line, while checking the heating hood height, and play the location of the heating hood, in order to make the same room or connected to the sill plate Elevation and vertical and horizontal position, installation should be a unified copy level, so that the elevation is uniform.
3.3 Check the embedded parts: Check and scribe, check the sill board, heating cover installation location of the embedded parts, whether the design and installation of the connection to meet the structural requirements, if errors should be amended.
3.4 Bracket installation: the need to set up the structure of the sill bracket, the installation should be checked before the fixed bracket embedded parts to confirm the elevation, location correct, according to the design structure of the bracket installation.
3.5 Window plate installation:
3.5.1 wooden windowsill board installation: wood brick in the top wall of the window wall, horizontal nail trapezoidal cross-section of wood (window width greater than 1m, the middle should be about 500mm pitch plus nail horizontal trapezoidal wood), in order to level the sill The bottom line. If the width of the sill is greater than 150mm, the bottom of the panel shall be worn darkly. The installation should be inserted into the sash under the hat head of the mouth, both ends into the window wall size should be consistent, to maintain the level, after correction with a flat nail crimping nails nail, nail cap into the wooden sill board 2mm.
3.5.2 prefabricated cement sill plate, prefabricated terrazzo sill plate, stone sill plate installation: according to design requirements to find a good location, pre-installed, elevation, location, wall size to meet the requirements, seam smooth, fixed parts Its structure of the fixed fixed formal installation.
3.5.3 installation of metal sill: According to the design and construction requirements, check the elevation, location, fixed parts, the first pre-installed, the inspection is correct, and then formally installed fixed.
3.6 heating hood installation: in the bottom of the window sill or on the ground to draw a position line, for positioning installation. Split plate heating cover joints should be flat, smooth, straight, Qi, upper and lower edge height, flatness should be consistent, the upper edge of the edge should be located in the outer edge of the sill plate.
4 quality standards
4.1 Warranty items:
4.1.1 The material, variety, size, shape and moisture content of the windowsill and radiator cover must meet the design requirements.
4.1.2 prefabricated processing of various types of window sills of the strength and stiffness should be consistent with the relevant standards and design requirements.
4.1.3 windowsill, heating hood must be designed according to the structure of a solid set, no loosening and other defects.
4.2 Basic Items:
4.2.1 processing the right size, smooth surface smooth, corner Founder no defects; consistent color design requirements; wooden windowsill panels and heating surface surface shall not exposed nail cap, should be no closure Cha, planing marks, burr, hammer India, etc. defect.
4.2.2 window plate, heating cover the correct installation position, cutting angle and tidy, seams tight, smooth straight. The sill board out of the wall size; heating cover concave window board size.
4.3 Permissible deviation items, see Table 9-52.
Table 9-52. Installation tolerances of window sills and radiators
Line item Allowable deviation (mm) Inspection method
1 level difference between the two levels check
2 both ends of the distance from the window hole 3 to check with the foot
3 Heating cover lateral position 3 Check with the ruler
5 protection of finished products
5.1 When installing sill board and heating mantle, the completed project shall be protected, and no finished product such as floor, window hole or corner may be damaged by operation.
5.2 window plate, heating cover approach should be properly kept, so that wood products are not damp, metal products do not rust, stone, the village does not damage the edges and corners, from pollution.
5.3 installed finished products should be protective measures, so that does not damage, no pollution.
6 should pay attention to quality problems
6.1 sill plate plug not into the window down the cap cap tank: construction should check the sill board installation conditions, the construction should adhere to pre-installed to meet the requirements after the fixed.
6.2 windowsill board at the end of pad is not real: twist gray lax; wooden, metal sill plate leveling level elevation inconsistent, uneven; construction to do each process seriously, leveling. Pad real, twist strict, fixed and reliable. Across the window frame bracket should be installed flat, so that the force even support.
6.3 splicing sill board more than uneven, not straight: processing window sill length, width deviation, thickness inconsistency. Construction should pay attention to the same specifications in the same position.
6.4 Heating hood installation uneven, not correct: due to pendant location are not allowed; construction should be fixed after the installation of heating cover fixed to ensure that the pressure into the same size.
7 Quality records
This process standard shall have the following quality records:
7.1 windowsill board, heating hood products should be factory certification, according to products, there should be strength, moisture test data.
7.2 installation of quality inspection and evaluation information.
