Technical Field
The invention relates to the field of concrete construction, in particular to a method for erecting an arc formwork of an exposed concrete diaphragm wall.
Background
In the construction process of the irregular curved-surface fair-faced concrete diaphragm wall, the size of the fair-faced diaphragm wall is large, general reinforcement measures cannot meet support and calculation of a frame body of a large-size member, and enough strength needs to be provided to ensure that joints of the circular clear water surface are smooth.
Disclosure of Invention
The invention aims to overcome the defects and provides a method for erecting an arc formwork of an exposed concrete diaphragm wall.
In order to achieve the above object, the present invention is realized by:
a method for erecting an arc formwork of an exposed concrete wall comprises
step 2, processing and manufacturing the back edges of the special-shaped templates by a full-automatic engraving machine, wherein 3 back edges with the thickness of 18mm are spliced into a back edge with the thickness of 54mm to serve as a reinforcing secondary keel at the bottom of a sheet wall beam, and the outer arc curved surface of the arc-shaped wooden shaping back edge starts to cancel arc line modeling at the position with the larger arc shape and is changed into a flat trapezoidal opening perpendicular to the inner arc surface of the back edge and the ground, so that the transverse main keel double-C-shaped steel section bar is ensured to have enough contact surface for reinforcing stress;
step 3, after the arc-shaped back edges are assembled, checking whether the elevation of the structural surface and the elevation of the top of the back edges are consistent with the elevation in the drawing, finding out the elevation of the top of an upward protruding point of the arc-shaped beam bottom by using a total station after the assembling is completed on site, rechecking the elevation, rechecking the measurement once every 1 m to meet the requirement of subsequent construction, then closing the side die, reinforcing the template after the assembling is completed, and finally rechecking the template according to the same method before the reinforcing;
step 4, paving the bottom template along the back edge by adopting a nail gun for the beam bottom circular arc section template, fixing the external joint by using a steel connecting sheet, and using a sponge adhesive tape for the splicing position of the template to prevent slurry leakage;
step 5, adopting the 14# channel steel as the main keel to place in the dish and detaining a tray and supporting, the channel steel top contacts with the protruding position of arc back of the body stupefied, will carry on the stupefied upper portion power of the body and transmit to the support frame on, adopt 16mm diameter high-strength national standard bolt to lock in the both sides of post simultaneously, increase the diagonal bracing member of dish knot frame left and right sides.
The method can conveniently carry out construction of the arc-shaped bottom of the fair-faced concrete partition wall, is simple, convenient and economical compared with other measures, can better find the elevation of the arc-shaped ground beam if the full-automatic template engraving machine can find the elevation of the arc-shaped ground beam, and is more accurate than general measurement positioning.
Drawings
Fig. 1 and 2 are schematic diagrams of the back edge of the special-shaped curved surface template disclosed by the invention.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in figures 1 and 2, the method for building the arc formwork of the bare concrete diaphragm wall comprises the following steps
step 2, processing and manufacturing the back edges of the special-shaped templates by a full-automatic engraving machine, wherein 3 back edges with the thickness of 18mm are spliced into a back edge with the thickness of 54mm to serve as a reinforcing secondary keel at the bottom of a sheet wall beam, and the outer arc curved surface of the arc-shaped wooden shaping back edge starts to cancel arc line modeling at the position with the larger arc shape and is changed into a flat trapezoidal opening perpendicular to the inner arc surface of the back edge and the ground, so that the transverse main keel double-C-shaped steel section bar is ensured to have enough contact surface for reinforcing stress;
step 3, after the arc-shaped back edges are assembled, checking whether the elevation of the structural surface and the elevation of the top of the back edges are consistent with the elevation in the drawing, finding out the elevation of the top of an upward protruding point of the arc-shaped beam bottom by using a total station after the assembling is completed on site, rechecking the elevation, rechecking the measurement once every 1 m to meet the requirement of subsequent construction, then closing the side die, reinforcing the template after the assembling is completed, and finally rechecking the template according to the same method before the reinforcing;
step 4, paving the bottom template along the back edge by adopting a nail gun for the beam bottom circular arc section template, fixing the external joint by using a steel connecting sheet, and using a sponge adhesive tape for the splicing position of the template to prevent slurry leakage;
step 5, adopting the 14# channel steel as the main keel to place in the dish and detaining a tray and supporting, the channel steel top contacts with the protruding position of arc back of the body stupefied, will carry on the stupefied upper portion power of the body and transmit to the support frame on, adopt 16mm diameter high-strength national standard bolt to lock in the both sides of post simultaneously, increase the diagonal bracing member of dish knot frame left and right sides.
