Detailed description of the invention
We do with the combination constructing method thereof of specific embodiment to modular communications column foot of the present invention by reference to the accompanying drawings and further elaborate below; understand working method and equipment composition in the hope of more cheer and bright, but the protection domain of patent of the present invention can not be limited with this.
The present invention proposed the thought of combined type communication tower base before this, column foot body is provided with in this combined type communication tower base, described column foot body comprises several base unit blocks mutually spliced, relative side, described base unit block position is parallel to each other, have in the side of described base unit block on a side or two adjacent sides and be provided with spacing block set, the stopper slot that the spacing block set that three sides in addition or two adjacent sides are provided with base unit block mutually isostructural with another matches, described column foot body horizontal and vertical is provided with several for what run through base unit block and is connected and fixed bar (prestressed reinforcement).Combined tower base has and can carry out dismantling, is convenient to change column foot position, effectively improves column foot utilization rate, effectively the beneficial effect such as can positions to column foot.
The present invention is a kind of combination constructing method thereof of modular communications column foot, and each described modular communications column foot includes nine pieces of prefabricated basic blocks, and these nine pieces prefabricated basic blocks are spliced into as integral type square block is as communication column foot.The present invention combines column foot basic blocks combination center cross integrated positioning, and combination foundation twice prestressed stretch-draw adjusts moulding process in place, and combination foundation has used prestressed stretch-draw dolly and tensioning equipment.The thinking of the method is by the prefabricated section (similar coordinate) in first built-up foundation central cross, and use prestressed reinforcement stretch-draw integral, just there has been a benchmark installed on whole basis, then from cross both sides all the other basic blocks of once mounting.
Based on above-mentioned thinking, combination constructing method thereof of the present invention includes following detailed step:
The first step, utilizes nine pieces of basic blocks of concrete prefabricated communication column foot, and prepare the prestressed reinforcement of stretch-draw, prestressed reinforcement here can be fining twisted steel.
Second step, is first spliced into cross as coordinate using piece basic blocks of five wherein, forms a central cross shape combination, uses prestressed reinforcement stretch-draw integral; The combination of central cross shape combination is: one piece of prefabricated foundation block is placed in centre position, and four limits that all the other four pieces of prefabricated foundation blocks are close to centre position prefabricated foundation block are respectively placed, as shown in Figure 1.The effect of prestressed reinforcement is herein for connecting prefabricated foundation block, and connects at the two ends of prestressed reinforcement configuration nut pad.
3rd step, again remaining four pieces of basic blocks are snapped onto respectively the corresponding site at four angles of central cross shape combination, as shown in Figure 2, and then prestressed reinforcing bar, tensioning equipment is used to carry out initial tensioning to all directions prestressed reinforcement, the pulling force of initial tensioning is 10% of design pulling force, to adjust the fissure of displacement and mutual alignment between combination prefabricated foundation block.Initial tensioning is the object reaching pretension is whether the prefabricated section got togather in order to check groups has dislocation, and can adjust in good time, and twice split is the technique in order to how once check rectification, reduce single tension split shaping after cause due to the reason of the fissure of displacement do over again.
4th step, carries out whole stretch-draw after adjusting each combination prefabricated foundation block, and the pulling force of whole stretch-draw is 100% of design pulling force, makes nine pieces of prefabricated foundation blocks be combined into a base integral, as shown in Figure 3.
The combination constructing method thereof combined type basis of modular communications column foot of the present invention is assembled can be the combination even combination of 36 basic blocks of the combination of 9 basic blocks, the combination of 16 basic blocks, 25 basic blocks.As long as based on structure design and the combination operation that utilizes construction method of the present invention to carry out of modular communications column foot; owing to being the operation of globality; also be all to take such combination four and combination construction process, these contents should be all the protection domains belonging to patent of the present invention.
In the combination constructing method thereof of modular communications column foot of the present invention, producing stretch-draw prestressing force is stretch-draw dolly and tensioning equipment, as shown in Figure 4, described stretch-draw dolly 3 rear portion is provided with storage position, anterior carries stretch-draw counter-force jack 4 by cantilever, is placed with the ballast 5 heavy with described tensioning equipment etc. in described storage position.Tensioning equipment includes stretching oil pump and stretch-draw counter-force jack 4, and stretch-draw counter-force jack 4 belongs to a tensioning equipment part.Stretch-draw dolly 3 is placed on above basic blocks 1, can promote arbitrarily, and because stretch-draw counter-force jack 4 is tensioning equipment parts, stretch-draw counter-force jack 4 is enclosed within prestressed reinforcement 2 and is fixed with cap colalr gasket.Make stretch-draw counter-force jack 4 style of work to play the effect of prestressed reinforcement of tensioning 2 in basic blocks 1 by controlling stretching oil pump during stretch-draw, stretch-draw locks prestressed reinforcement 2 to when designing stretching force with nut.
The bottom of above-mentioned stretch-draw dolly 3 is configured with multiple universal wheel 6 that freely can promote to turn in construction.The combination foundation of communication column foot is with prestressed stretch-draw dolly and stretch-draw a complete set of equipment, according to the ballast formula stretch-draw dolly of construction characteristic configuration, the bottom of stretch-draw dolly 3 is equipped with universal wheel 6 and freely can promotes to turn in construction, farthest meet the construction requirement of modular communications column foot combination stretch-draw under all kinds of operating mode, stretch-draw dolly can at ballasts such as rear portion storage position place tool and tensioning equipments in the process of carrying out stretch-draw, ensure that uniform force after stretch-draw Plantago minuta, there will not be because stressed excessive the making it in front portion exists the danger of toppling, substantially increase the safety in work progress, meet construction requirement, convenient and practical, eliminate the use of the crane gears such as crane, the stretch-draw time is greatly reduced.
Combined communication column foot construction technology of the present invention is by orderly adjustment combination foundation block built-up sequence, stretch-draw adjustment piece has misplaced prestressed stretch-draw at twice, the stretch-draw dolly made according to this combination construction feature and tensioning equipment, under the prerequisite meeting combination construction requirement, farthest have compressed the combination construction time, fully demonstrate the highly effective of modular communications column foot construction.
