[0039] The outer formwork is made in blocks and installed to the top at one time; first, the outer scaffolding is used as support, and crossbars with a spacing of 1.2m are installed to control the position of the lining mold at different elevations; the keel is made of high-quality white pine wood square of 50mm×100mm×4000mm. Temporarily fix it with iron wire and steel pipe for slope control, and then install the wooden mold lining mold in blocks. The rear lining mirror panel 1 is 1220mm×2440mm×18mm thick. The rear lining mirror panel 1 is installed with the template and template Double-sided tape is used for sealing to ensure that the joints of the formwork do not leak; the rear lining mirror panel 1 is supported to the top at a time according to the top elevation of the building during construction, and the slope of the wall can be well guaranteed by the above methods; The convex wooden strip 2 will not deform under the pressure of the concrete side. Therefore, the trapezoidal convex wooden strip 2 that is easy to demold is selected, and the diameter of the convex wooden strip 2 is selected as the raw material. The length of the convex wooden strip 2 in this interval should not be greater than 2.5m ; The cross-section specifications of the specific convex wooden strip 2 and the size of the head can be selected according to the decoration requirements;

[0040] ③Wooden model typesetting;

[0041] In order to ensure that the slope of the wooden mold is parallel to the cornice, the outer template must be set up to the design elevation at a time, and then the convex wooden strip 2 is typeset and stretched from top to bottom; to ensure that the convex wooden strip 2 is equally spaced, the convex wooden When the strip 2 is assembled, the big end should be connected to the big end, and the small end should be connected to the small end. At the same time, the joint positions should be staggered to make the distance between the bamboo molds change slowly, so as to ensure the look and feel of the convex wooden strip 2 concrete after molding;

[0042] ④ Wooden mold installation;

[0043] After the typesetting of the convex wooden strip 2 is completed, the convex wooden strip 2 can be nailed from the bottom up. The convex wooden strip 2 is nailed by 30mm air nails 3 at the upper and lower edges of the convex wooden strip 2 at a distance of 30mm. 2 The ends of both sides should be appropriately densely spaced; because the convex wooden strip 2 is made manually, there are more or less gaps between the convex wooden strip 2 and the backing mirror panel 1 template to ensure concrete Do not enter between the convex wood strip 2 and the back mirror panel 1. The convex wood strip 2 and the back mirror panel 1 are sealed with transparent glass glue; at the same time, the joint of the convex wood strip 2 should be properly corrected with a planer. So as to ensure the smoothness and straightness of the joints; when the wall concrete is poured in stages, the height of the convex wooden strip 2 pattern template should be controlled at 80-100cm above the concrete graded height, as the upper convex wooden strip 2 typesetting and nailing Basis.

[0044] In the foregoing, as attached figure 2 As shown, the rear lining mirror panel 1 is uniformly spaced and fixed convex wooden strips 2 in the same direction. The cross-section of the convex wooden strips 2 is trapezoidal; the top surface of the convex wooden strips 2 is 80-100mm wide, and the distance between the bottom edges of two adjacent convex wooden strips 2 is 15- 30mm.

[0045] In the embodiment of the present invention, the method of the detailed node of the wooden formwork;

[0046] (1) The method of the external angle: the external angle adopts the internal concave method, and the outside of the external angle adopts a 50mm×50mm wooden square seal, and each side is recessed into the minimum section of the wall by 5cm after the mold is removed;

[0047] (2) Door and window opening method: Because the cornice on the outer wall of the building has a certain slope, the outer eave of the window hole is parallel to the building cornice, and the inner eave of the window hole is kept level with the horizontal plane. At the same time, a 10mm×20mm stainless steel drip is set on the outer cornice of the window hole. The lines are dripping.

[0048] In the embodiment of the present invention, the pull bolts are installed;

[0049] The outer wall of the project is a fair-faced concrete wall. In order to ensure that the surface of the template and the arrangement of the screw holes are beautiful and orderly when the rear mirror panel 1 is removed, the high-quality PPR water supply pipe is selected on site, and the inner sleeve is used to pull the screw. Reinforce the template.

[0050] According to the height of the exterior wall of the building, the embodiment of the present invention adopts a 1220mm×2440mm×18mm rear lining mirror panel 1 to prepare a lining mold, and then composes elastic lines on the rear lining mirror panel 1 from top to bottom, and then from bottom to bottom A trapezoidal cross-section convex wooden strip 2 with a length of about 3m is nailed, and the lining mold is tied to the inner side formwork of the outer wall by Ф12mm paired bolts. The entire formwork system is formed by the inner and outer steel pipe scaffolding to form a stable and reliable support system, and the concrete pouring is completed. After molding, the decorative effect of the wooden striped clear water concrete wall is formed.

[0051] The principle of the embodiment of the present invention is that the exterior wall of the building is finished with wood grain clear water concrete, and the trapezoidal cross-section convex wood strips 2 are selected and fixed on the back mirror panel 1 template to make a wood grain template, and 1.5 are left between the convex wood strips 2 With a gap of ~3cm, after the concrete is poured, the surface of the wall will form a concave-convex orderly decorative effect, creating a precedent for decorative concrete and saving a lot of decoration time, manpower and materials.

Example Embodiment
