Detailed Description
The invention is further illustrated by the following specific examples.
A method for pre-assembling and erecting a high and large coil buckle type scaffold comprises coil buckle scaffold upright rods, cross rods, diagonal draw bars and pins; the setting-up method comprises
Step 1, judging a pre-assembly scheme specifically adopted according to the height of a support, preferably selecting a mixed pre-assembly method when the height of the support is more than 10 meters or the working condition is complex, preferably selecting a horizontal assembly method when the height of the support is 6-10 meters, and preferably selecting a vertical pre-assembly method when the height of the support is not more than 6 meters;
step 2, dividing the whole support into unit modules according to the support scheme, wherein the unit modules are preferably rectangular and symmetrically designed, and the number of vertical cross bars and the number of rods on two sides of the central axis are kept consistent; the specific principle is related to which pre-assembly method is selected; when a vertical pre-assembly method is adopted, the length and the width of the vertical pre-assembly method are not more than 6m, and the pre-assembly height is not more than 6m; when a horizontal pre-assembly method is adopted, the width is not more than 6m, the height is not more than 5m, and the length in the vertical rod direction is not more than 10m; the diagonal draw bar arrangement of each unit module at least meets the interval one-span arrangement;
step 3, according to the design of the unit modules, pre-assembling the unit modules outside the construction site, numbering the unit modules in sequence according to the assembling sequence, and marking the orientation of the upright stanchion, the module number and the module number connected with the upright stanchion on four sides of the unit modules by arrows and letters;
step 4, measuring and setting out on a construction site, and positioning the position of each upright rod of each unit module;
step 5, utilizing hoisting equipment to assemble the unit modules into a whole one by one, hoisting the 1 st module to a specified position during assembly, ensuring the position of each upright of the 1 st module to be accurate, determining that the orientation of the upright sleeve is consistent with the scheme, and sequentially installing other modules after the 1 st module is installed; when the assembly is carried out horizontally, the distance between the 1 st module and the adjacent module is strictly controlled to be the distance between the coiling buckle cross rods, and after the position of the vertical rod is confirmed to be error-free, all the modules are connected into a whole by the cross rods.
In the construction method, the unit module design of the vertical pre-assembly method is as follows:
the unit module consists of a plurality of vertical rods (11), a cross rod (12), an inclined pull rod (13) and a pin (14), as shown in figures 1a and 1 b. The size of the module is not too large or too small during module design. Should detain the pole setting by 4 dishes at least and 4 dishes detain the horizontal pole and constitute, its length, width, height all use to be no more than 6m as the fit, too big can increase the hoist and mount degree of difficulty and at hoist and mount in-process volatile steady, too high can reduce pre-assembly efficiency and increase the high altitude construction safety risk.
The coil buckle upright rod (11) used by the unit module is vertically arranged when being erected, and the arrangement of the inclined pull rod (13) at least meets the requirement of interval one-span arrangement for increasing the overall stability. The extension of the single module uprights must be done using a pin connection (14) to avoid the uprights falling off during the module transport. After the unit modules are assembled, the numbers Mn, the directions (marked by arrows) and the numbers Mk of adjacent modules are marked at the top and bottom ends of the four Zhou Li rods, and the numbers Mn, the directions (marked by the arrow and the direction by the letter S, N, E, W) and the numbers Mx of adjacent modules are marked on the cross rods on the periphery, so that the subsequent integral installation is facilitated, as shown in FIG. 1 c.
In the construction method, the horizontal pre-assembly method unit module is designed as follows:
the module is also composed of a plurality of vertical rods (21), a cross rod (22), a diagonal draw bar (23) and a pin (24), as shown in fig. 2a and 2 b. The design size of the module is different from that of a vertical pre-assembly method, the length of the module is not larger than 10m, the width of the module is not larger than 6m, and the height of the module is not larger than 5m. Too big length and width are unfavorable for whole assembly and the easy unstability of hoist and mount in-process, and high height can reduce pre-assembly efficiency and increase aerial work safety risk. The module should have 4 dish to detain the pole setting, 4 dish to detain the horizontal pole group at least.
The design of the unit module is a pre-assembly method for transversely arranging the disc buckle vertical rods, the arrangement of the diagonal draw bars for increasing the stability of the unit module at least meets the arrangement of 1 span at intervals, and the extension of the vertical rods must be connected by using pins so as to prevent the vertical rods from falling off in the module transportation process. After the unit modules are assembled, marks are made at corresponding positions of the vertical rods and the cross rods on the periphery, and the marking rules are consistent with those of the unit modules of the vertical pre-assembly method, as shown in fig. 2 c.
In the construction method, the vertical pre-assembly method is used for integral assembly:
the integral assembly is to assemble all the modules into a whole by utilizing machines such as a tower crane, a crane and the like on a construction site. The whole assembly of the method comprises horizontal assembly and vertical assembly, wherein the assembly is carried out according to the principle of firstly carrying out horizontal and then carrying out vertical, the assembly is carried out by firstly positioning the M1 module (the 1 st module), and the installation of other modules is carried out in sequence according to the logic numbers among the modules after repeatedly confirming the positions and elevations of the vertical rods on the periphery of the module. When other modules are horizontally installed, the distance between the four Zhou Ligan and the upright rods of the adjacent modules in place is determined to be the distance of a cross rod; when assembling in the vertical direction, the upper ends of the vertical rods around the lower unit module are provided with a guiding device so that the upper module can be positioned conveniently. As shown in fig. 3a and 3b, the modules are finally assembled into 1 unit.
In the construction method, the horizontal pre-assembly method is used for integral assembly:
because the vertical rod of the plate buckle under the horizontal pre-assembly method is placed horizontally, before the whole assembly, the required modules are firstly hoisted and vertically placed by using machines such as a tower crane, a truck crane and the like, and then the whole assembly can be completely referred to the vertical pre-assembly method in the installation sequence, as shown in fig. 4.
