The specific embodiment
With reference to shown in Figure 4, the invention discloses a kind of large-scale hollow out embossment hollow stone column construction method as Fig. 1, it may further comprise the steps:
(1) thick embryo segmentation: because large-scale stone column 1 has length, self-characteristic that volume and weight is big, its preparation method is different from the global formation preparation method that middle-size and small-size stone column uses, need to adopt computer composition, large-scale stone column 1 is divided into plurality of sections, with stone column 1 each section is the unit, carries out processing and fabricating respectively.But the definite main operational degree of considering large-scale stone column 1 in transportation and lifting link of section length, especially the influence of factors such as load is laid, lifted by crane to suspension centre, general useful size with section length (being the section length of stone column after the machine-shaping) is controlled between 1.0m～2.0m, section length reduces with the increase of the external diameter of large-scale hollow stone column 1, increase with internal diameter increases, and the useful size of the thick embryo section length of the normal large-scale hollow stone column 1 that adopts is 1.0m, 1.5m, 2.0m.
(2) loose core piecemeal: the thick embryo of the stone column after the segmentation is kept flat, according to the pre-designed diameter dimension of loosing core, building stones in the thick embryo are dug out, and then use small instruments and tools manual amendment stone column 1 internal diameter to designing requirement, shown in Fig. 2 A is to loose core to stay stone column 1 segmenting unit of tenon after 10.The size of 10 diameters of loosing core is determined by the internal diameter of hollow stone column finished product, about the general little 5cm of internal diameter than stone column 1 finished product.And factors such as the tenon size of definite needs consideration hollow stone column-core concrete combining structure stressing conditions of stone column 1 finished product internal diameter, stone column 1 external diameter size, each section of stone column termination, concrete casting fluence generally are not less than 15cm.
(3) tenon is stayed in the termination: for guaranteeing that stone column 1 each section combination is tight, being connected firmly, each section termination is all stayed and is established tenon.Installation in position order according to stone column 1, the lower end of each section stone column 1 is stayed and is established annular groove 11 (shown in Fig. 2 B), the upper end is stayed and is established annular tenon 12 (shown in Fig. 2 A), with groove 11 and the tenon 12 of adjacent hypomere stone column upper end, the tenon 12 of stone column 1 upper end and groove 11 concavo-convex the interlocking of adjacent epimere stone column 1 lower end that guarantee each section stone column 1 lower end.The width of tenon 12 and the concavo-convex degree of depth generally are no more than 5cm, and the width of groove 11 and the degree of depth are often than tenon 12 width and the big 0.5cm～1cm of the degree of depth, and the tenon outward flange is not less than 5cm apart from the stone column outside, and the tenon inward flange is not less than 5cm apart from stone column 1 inner edge.
(4) suspension centre is determined (shown in Fig. 3 A, Fig. 3 B): during 1 lifting of each section stone column, the hitcher that must avoid lifting contacts with the hollow out embossment of stone column outer surface with hoist cable, in order to avoid damaged hollow out embossment, therefore, suspension centre 13 is arranged on the inwall of each section stone column 1.For guaranteeing the steady of each section stone column 1 lifting, to set up and put four suspension centres 13, suspension centre 13 all is positioned on the same horizontal plane of each section stone column 1 inwall, apart from 1/3 position, stone column 1 upper end, shown in Fig. 5 .2-3.In addition, for guaranteeing stone column 1 in hoisting process, suspension centre 13 positions can not concentrated because of stress, cliff is crossed thin and caused stone column 1 breakage at suspension centre place, require suspension centre 13 pitch-rows from about 1/2 wall thickness of stone column inner wall edge, for conveniently punching and laying hitcher, suspension centre 13 holes all connect to tenon 12 places.
(5) through-carved work: because large-scale hollow stone column 1 adopts sectional making, its through-carved work can not one-shot forming as traditional middle-size and small-size stone carving method, also needs segmentation to carve.For the hollow out embossment that guarantees each section stone column 1 behind installation forming, the assembly unit of last hypomere depiction is intact, in conjunction with closely, adopts computer composition sectional making technology in advance.Hollow out anaglyph figure according to the 1:1 ratio depicts construction drawing as earlier, and construction drawing is attached to stone column 1 surface, again to the figure engraving.After finishing, the engraving first draft, by the construction drawing original copy engraving first draft is mended China ink then, effect audit once more after finishing impression is finished with construction drawing contrast, finishing.
(6) each section is pre-pieces together: after each section engraving of large-scale hollow out embossment hollow stone column 1 is finished, need be combined into type in advance in factory, whether have problems such as dislocation after the 1 assembly unit moulding of inspection stone column between each section.During pre-the assembly, stone column 1 each section be lifting successively from bottom to up.Need before the lifting to check whether hook, hoist cable connect firm, the normal autocrane that adopts of lifting.
(7) check finishing: after the 1 pre-assembly unit of each section stone column was finished, the main contents of inspection comprised the embossing pattern between each section stone column 1, the size of each section stone column 1 and overall dimensions three aspects after stone column 1 assembly unit.Problems such as suitable, no hollow out dislocation should be smoothly justified in the connection of hollow out embossing pattern between each section stone column 1, the concavo-convex unanimity of answering; The governing factor of each section stone column 1 size mainly comprises aspects such as length, width, thickness, corner and warpage, and the permissible variation that requires every index is all in control range; Overall dimensions after stone column 1 assembly unit should satisfy the size Control requirement of large-scale hollow out embossment hollow stone column after in place at the scene, mainly comprises factors such as position skew, straight, piece width suitable for reading, piece difference of height.
(8) protection transportation: large-scale hollow out embossment hollow stone column has the artistry of stone carving; the stone carving feature that before dispatching from the factory, just possesses; for avoid each section stone column carrying, in the transportation because of collision damages the hollow out embossment, must take rational safeguard measure, satisfy the protection high request between its delivery period.The surfaces externally and internally of each section stone column 1 all adopts flexible material to carry out totally-enclosed parcel protection.In addition, also guarantee stone column 1 each section in whole transportation, each section all placed separately, do not contact mutually, the bracing frame of every section stone column 1 all supports stone column from stone column 1 internal diameter, makes stone column 1 be in vacant state, avoids the hollow out embossment of stone column 1 outer surface to contact with surrounding environment.Even because support rocks, make stone column and near object produce collision, also can or not cause stone column 1 breakage because of the safeguard measure that has adopted interior outer wrapping.
(9) foundation construction: large-scale hollow out embossment hollow stone column belongs to towering structure, the requirement height Anti-Typhoon to antidetonation, and its resistance to overturning requires tight, and the basis pile foundations that adopt are provided with cushion cap again on it.Should hang when steel reinforcement cage is transferred straight, aim at, slowly descend, avoid come-up, also should avoid cutting pile lining to cause landslide; When building the pile foundation concrete, accelerate poring rate; Guarantee pile foundation and the concrete casting quality of cushion cap.
(10) set up scaffold (as shown in Figure 4): on adjacent hypomere stone column 1 in place before, need play glue at the stone column that finishes in place 1 tenon place, whether the hollow out embossment that also needs manually closely to check the hypomere stone column is aimed at.Therefore, must around stone column 1, set up one and enclose independently support 5.Since stone column 1 support 5 have projected area little, highly big, with the characteristics of stone column 1 separate (as if be connected fragile hollow out embossment with stone column), its less stable, but its security requirement height.The support of setting up 5 requires the steel pipe level, between the upper and lower apart from all being not more than 0.6m, often considers with the common divisor of stone column section length, promptly often adopts the spacing of 0.5m.The support of setting up, the tubular of circle foreign side in being, facade is all established bearing diagonal.
(11) set up shaft steel reinforcement cage (as shown in Figure 4): the purpose of setting up shaft steel reinforcement cage 3 is for casting reinforced concrete in hollow stone column 1, form on " hollow stone column-core concrete combined structure system ", thereby strengthen the resistance to overturning of large-scale hollow stone column 1, strengthen the Anti-Typhoon performance of antidetonation of structures.Shaft steel reinforcement cage 3 is positioned at hollow stone column 1, and steel reinforcement cage 3 should reduce the piece-ups of same reinforcing bar apart from the about 10cm of stone column 1 inward flange as far as possible, and the number of steel bars of same joint location can reach 100%.
(12) modulation rubber cement: the tenon between stone column 1 each section need connect with rubber cement, guarantee that not only hypomere can not produce dislocation in time on the stone column, the concrete grout that can also prevent cast in the stone column 1 can seepage flow to the hollow out embossment on stone column 1 surface, and pollute stone carving.The bonding agent (as CT83) that adopts should be strict with packing instruction control water distribution ratio, guarantees the clean level of water and agitator, and carrying out discharges water earlier afterwards puts dry powder, and the principle that whole bag stirs stirs into the moderate rubber cement of denseness with low-speed agitator.The rubber cement that mixes up should use up in 2 hours.
(13) lifting piecemeal: the lifting appliance of lifting use mostly is autocrane piecemeal.Elder generation according to the installation in position serial number, is carried to each section stone column 1 near the installation site successively, and is in the radius of clean-up scope of crane.The flat mode that keeps flat of hanging is adopted in lifting, must fixed hook before the lifting, adjust sling length, also should add cable rope sometimes, so that control the adjustment of stone column 1 on-station position.During lifting, when earlier each section stone column 1 being winched on the shaft steel reinforcement cage top 0.5m left and right sides, begin to adjust stone column 1 and transfer the position; After adjusting, the position again stone column 1 is slowly hung 0.1m place to the on-station position, whether hypomere stone column embossing pattern is aimed at substantially in the inspection, just slowly fall stone column behind the aligning, last hypomere stone column 1 tenon 12 and groove 11 (shown in Fig. 2 A, Fig. 2 B) want correspondence to interlock, and are in place; Whether the hollow out embossment of hypomere stone column is aimed at fully on the last scrutiny, if necessary, also can manually rotate the epimere stone column a little.
