Technical field

This composite set relates to building field, the template in high-rise building construction reinforced bar cement pouring technique and supporting way and handling building materials and the required box of decoration of exterior wall of mould bases.

Background technology

The building high-rise building is when reinforced concrete waters at present, the framework and the supporting way that adopt, to adopt a large amount of iron pipes to become support body with iron stand, template is layered on support body, support body is stressed on the floor of lower one deck, the structure support body needs a large amount of manpower and time, and pouring one deck building will go to disassemble and support structure support body tens times with same loaded down with trivial details method, so duration speed is slow.The handling apparatus of high-rise building use at present is tower crane type, the weak point of tower crane be exactly its pedestal be all to be inserted into desired height from ground always, the steel of the higher use of pedestal are just more, and difficulty is larger, so stability just needs heavy bracing frame and balance back up weight should have an easy handling apparatus to replace it during poorer handling material.Box adopts at present be cucurbit draw high this device of formula draw high very loaded down with trivial details, science not, box is in the support of vertical exterior wall and to hang difficulty large, poor stability, the comprehensive above not enough more scientific easier composite set of seeking thus.

Summary of the invention

Set up the method for reinforced concrete mould bases and support and the box of handling apparatus and exterior wall in building operations for high-rise building, now release a kind of novel constructional device of three projects combos on a pedestal, this device construction safety in utilization is strong, duration that builds a house can shorten, purpose of design is for the build a building bracing frame of handling building materials of improvement sets up the conventional mounting mode that up is increased to desired height from ground always.during for improvement building pouring reinforced concrete framework, the frame structure of template and the stressed basic point of support, its main purpose is with the weight of pouring reinforced concrete framework and the weight of template support body, reach frame with a lot of pipe fittings and support stressed method below original traditional support body, be improved to stressed on the groined type support body take these foundations as supporting base point, the method has been improved when pouring reinforced concrete framework, for stablizing template and supporting the weight of watering the reinforced concrete framework, the group structure of the fastening and supporting frame of loaded down with trivial details ironware in construction, a large amount of manpower and time had both been needed, need again a lot of pipe fittings to support and reach frame, the appearance of this scheme is for the pouring technique of building high-rise building, it is once great improvement, it can make the manpower that is used for framework support shuttering support body in pouring reinforced concrete frame construction, material resources reduce 2/3, framework time decreased 2/3, design principle, the reinforced concrete pouring one deck in house, pedestal exchanges jacking one deck under stressed effect at hydraulic means and support iron prop, this composite set is applicable to carry out respectively simultaneously the ornamental work of room body reinforced concrete framework pouring and exterior wall in the high-rise building construction, following content divides three parts to describe 1, the composite set 2 of handling apparatus and box and well cabinet frame and load-bearing reinforced concrete framework pouring layer, the stressed method 3 of the exchange of the body jacking of well cabinet frame and support, the disassembling method of composite set.

1, the composite set of handling apparatus and box and well cabinet frame and load-bearing reinforced concrete framework pouring layer.

This device adopts large-scale i iron to consist of a groined type support body with the ironware knot.according to the flat shape of this construction building and the locations of structures of size and every one deck pouring reinforced concrete crossbeam, the position of beam structure is different, the locations of structures of support body difference just, support body can be adjusted to the size shape of rectangle and plurality of specifications, support body is respectively by twice structure, for the first time i-beam structure is become large shape groined type body frame, fix with ironware, augment the channel-section steel support body according to the crossbeam position of these construction foundations for the second time, be fixed on large-scale body frame, the support of support body divides two kinds, a kind of is two functions of jacking and support, another kind is simple support, only has the function of support, the structure of jacking and the strong point, support brandreth by one (2.5 meters * 1.2 meters * 0.24 meter), a hydraulic jacking device, 2 are supported the iron prop establishment and form, 2 are supported iron prop and hydraulic top lifting shaft triangularity, 2 are supported iron prop at a distance of 0.9 meter, the hydraulic top lifting shaft is over against the other crossbeam of column, 0.15 meter of iron prop diameter, for thickening hollow section, (horizontal plane calculates below the well cabinet frame) is long as 3.35 meters, support the nut that termination, iron prop lower end is provided with 0.06 rice diameter, welding forms by car system, require good concentricity, strong point support body is done with the I-shaped steel, simple strong point structure is the same with the strong point with jacking does not just have the jacking hydraulic means, can directly be fixed on large-scale support body supporting iron prop, raise with the jacking of well cabinet frame, so be fixed on because supporting iron prop that height position on the groined type support body is different all will be as the criterion with well cabinet frame horizontal plane when the support iron column length is set, determine to support the length of 3.35 meters of iron props, but 3.5 meters height of the disposable synchronization of jacking up of jacking hydraulic means, support body and parts are disassembled.

the first step is according to the beam structure position of these construction foundations, be arranged on the frame structure shape on foundations, lay the method for 2 channel-section steels by each root crossbeam of foundations and carry out the structure support body, 2 channel-section steels pendulum is in the left and right of crossbeam, one on one side, position at a distance of 1 meter left and right, 2 channel-section steels are fixed on large-scale well cabinet frame lower end, the effect of 2 channel-section steels is mainly used in holding in the palm template and mould bases and the weight of hanging reinforced concrete pouring layer, method is hung in holder, the termination, upper end of holder suspension rod is locked on channel-section steel with ironware by the position that mould bases needs, the symmetrical locking of crossbeam place's holder suspension rod, then will hold in the palm the suspension rod lower end head rest mould bases of slinging, mould bases adopts channel-section steel, template is layered on the mould bases channel-section steel again, reach the purpose that holder is hung, unclamp the iron fastener during decentering, mould bases is both dismountable.The holder suspension rod with the Combined shelf body jacking improve a lot of holder suspension rods can appear on floor this moment and support iron prop when the pouring because of erect-position, make this floor fail casting cement and circular hole occurs.Collar tie beam for four limit outmost turns of this construction building, reinforced concrete waters the method to set up that is filled in template in construction process and mould bases and casting cement frame beam body weight, because there is no the vertical support basic point at outermost ring box Liang Waiqiangchu, so the method that adopts holder to hang and support matches, thus template and mould bases holder are hung on well cabinet frame body, hang mould bases body lower end vertical support but should adopt iron prop to support with holder in the weight of pouring reinforced concrete crossbeam process central sill body.according to said method, about every crossbeam of these foundations, each 1 channel-section steel is set all, as shown in figure " 6 ", the channel-section steel that will be arranged on thus about crossbeam becomes a whole support body with large shape groined type main frame structure, when large shape groined type body frame is set, just the girder steel of main frame body should be arranged on the crossbeam left and right of foundations, each i iron, the arrangement method of large shape well cabinet frame, for convenience of description, we are called for short at will construct four limits of foundations, east, south, the west, it is on foundations that north is wanted to describe clear thus, as: these foundations need the large shape groined type support body of (30 meters * 30 meters).we are at first with 4 12 meters long i iron in the east so, be divided into 2 groups, 2 one group, the parallel of 2 i iron of a group is 1.2 meters apart, be 10 meters apart between 2 groups, 2 groups of i iron in east are apart 10 meters thus, so the equilibrium phase of 2 groups of i iron in west distance should be also 10 meters, eastern thus, the i iron on both sides, west forms symmetrical form, because of the specification of large shape well cabinet frame be (30 meters * 30 meters) so 30 meters deduct east, the length that the symmetrical i iron in both sides, west is 12 meters, eastern thus, span between the i iron of both sides, west symmetry is exactly 6 meters wide, now overlap east with 10 meters long i iron, on 6 meters wide spans of i iron of west two symmetries, fix with ironware.adopt same specification and same method, with south, after the i-beam structure on both sides, north is good, it is overlapped east, on the i iron of west symmetry, form a large shape groined type body frame, as: the groined type body frame need to dwindle, so with east, south, the west, 12 meters long i iron on four limits, north shrink to the centre, but be reduced at most east, south, the west, the termination of 12 meters long i iron on four limits, north contacts, that is to say that the groined type body frame is not less than (24 meters * 24 meters), when the groined type body frame is set, should decide according to the structural factor of the vertical exterior wall of this building of constructing, because groined type body frame support body need to be paid 1.5 meters to 3.5 meters of vertical exterior walls, expenditure support body length partly is used for hook box and handling constructional materials, vertical wall face place, some places are solar panel and the vertical exterior wall of balcony expenditure, when so the groined type body frame is installed, the length of the vertical exterior wall of support body expenditure, should be with box when the vertical lifting, the balcony and the solar panel that do not contact exterior wall are as the criterion, but the support body length of paying vertical exterior wall can not be greater than 3.5 meters, the setting of box is a limit, formed by 2 main boxes and 6 minutes boxes, main box is (12 meters * 1.8 meters * 1 meter), main box is welded and fixed, dividing box is that (6 meters * 3.5 meters * 1 meter) build with ironware is fixing at the construction field (site) with iron pipe, two main boxes are hooked on respectively on the i iron of the vertical exterior wall of well cabinet frame expenditure, fix with ironware, after two main box hooks hang up properly, span position between two main boxes is connected and fixed with ironware, then on average be hooked on 6 minutes boxes respectively on the iron pipe of main box fixing again with its integral reinforcing.

the handling constructional materials, adopt hoist engine, hoist engine is the crane capacity of 1 ton, hoist engine is arranged on by the strong point on the groined type support body, the supporting wire rope of hoist engine is under the stressed cooperation of each position movable pulley of groined type support body, can adopt the i iron of the vertical exterior wall hook box of groined type support body expenditure to make bracing frame, object from the ground handling on box, for constructional materials being phoresied at the foundations center, 12 meters long i iron can be set specially to be fixed on large-scale support body with ironware, 3.5 meters pedestals of doing handling of the steel body vertical exterior wall of expenditure with i iron, the steel tank of i iron is the rolling roadbed of pulley brandreth car, the stroke of pulley brandreth car on steel tank is 11.5 meters, the stroke of pulley brandreth car can vertically hang on building materials from ground box, then utilize steel tank to phoresy again at the foundations center, as: when object need to phoresy at the housing base center, at first pulley brandreth lock is fixed on the termination at 3.5 meters of i iron expenditure exterior wall, the supporting wire rope of hoist engine is stressed in the movable pulley at each position afterwards, object is winched to 0.6 meter, pulley brandreth car from ground, hoist engine stops, by the office that is arranged on pulley brandreth car, the weight of whole object is hooked in office, stressed on pulley brandreth car, the office that will lock the pulley brandreth this moment opens, hoist engine starts pulley brandreth car is rolled with steel tank object is phoresied the destination, this moment, hoist engine stopped, locking pulley brandreth car, hoist engine is sling object on a small quantity, the office of hook object can be opened, then the object of handling falls after rise, complete thus the whole process of phoresying.

2, composite set exchanges stressed jacking and method for supporting

The strong point is the stressed basic point of bearing whole composite set support body weight and this reinforced concrete pouring layer weight, it should be according to the weight of bearing and every material that supports iron prop, the ability of energy load-bearing decides the position of the strong point and the number of the strong point, the weight that the whole strong point be should bear is, the total weight of the weight on whole composite set and this reinforced concrete ccf layer.And the jacking weight that hydraulic lifting be should bear is the total weight on whole composite set, so some positions only need to arrange the strong point, the support iron prop that arranges promotes with jacking, because the weight of the weight that should support and jacking is uncertain factor, the position of the strong point and the number that the strong point needs therefore now can't have been determined.so the measure of stressed method and stable support composite set of jacking can only being exchanged now is described, the support body of composite set is by the hydraulic means of jacking and the strong point and supports iron prop and exchange stressed jacking and support, the jacking basic point of hydraulic means is on the other crossbeam of reinforced concrete upright of frame, when hydraulic means during whole well cabinet frame synchronism stability jacking to 3.5 meter height, the support iron prop of all strong points is fixed on the position of well cabinet frame locking, after the support iron prop fixes, hydraulic means relief well cabinet frame simultaneously synchronously falls after rise, support iron prop stressed in carrying on a shoulder pole on the irony backing plate on crossbeam, the irony backing plate is transmitted to pressure on the crossbeam of reinforced concrete framework, the irony backing plate is (1.2 meters * 0.2 meter * 0.08 meter), middle at a distance of 0.9 meter in irony backing plate entire length, make the diameter den identical with supporting iron prop and the through hole of 0.065 meter left and right, the den of irony backing plate is used for the lock support iron prop when supporting stressed position, the through hole of irony backing plate, be used for when supporting iron prop stressed in the irony backing plate, support the nut that termination, iron prop lower end is set, through hole over against the irony backing plate, adopting thus diameter is the lead screw of 0.06 meter, pass floor and irony backing plate, this lead screw is fastening with the nut of support iron prop lower end, the support iron prop of all strong points is fixed on crossbeam and floor, as shown in figure " 3 ", make its whole well cabinet frame good stability, when supporting that iron prop is stressed supports the well cabinet frame at 3.5 meters high, this foundations horizontal plane, in pouring second layer reinforced concrete frame construction, because the support iron prop of well cabinet frame is to be supported on the first floor foundations, and the whole horizontal plane of the reinforced concrete framework of second layer pouring is in the lower end of well cabinet frame horizontal plane, so when pouring second layer reinforced concrete framework and floor, the support iron prop place of all strong points, just fail pouring because supporting iron prop institute station location, as shown in figure " 3 ", therefore when hydraulic means raises the well cabinet frame again, supporting iron prop rises with the well cabinet frame, so fail casting cement in the former support iron prop of second layer floor position with regard to the same circular hole of support iron column diameter having occurred, this moment with irony backing plate cross-arm on the crossbeam of second layer reinforced concrete framework, auxiliary pad is in second layer floor level, two through holes of irony backing plate are over against the nut that supports the iron prop lower end, due to the diameter that supports iron prop be 0.15 meter greater than 0.065 meter of the through hole of irony backing plate, so support when the well cabinet frame falls after rise iron prop with regard to stressed on the irony backing plate, adopt the method, well cabinet frame jacking one deck, support iron prop and be fixed on crossbeam and floor once, pouring one deck reinforced concrete framework.

In well cabinet frame jacking process, for security consideration, prevent well cabinet frame centre-of gravity shift, now make 2 suggestions, 1, the area of the jacking axle of all hydraulic device and foundations contacts site is increased, the meaning is exactly as the people when standing form, and sole area and area of base are increased, and is stable just better.2, such as: when lift-up device during well cabinet frame jacking to 3 meter, the support iron prop of well cabinet frame has promoted 3 meters with the well cabinet frame, this moment the well cabinet frame strong point the support iron prop, just also has the cylinder of 0.4 meter left and right also in watering the floor through hole that solidifies, also the cylinder in the floor through hole also plays the stabilization of well cabinet frame vertical lifting, but played the side effect of cylinder and floor opening wall friction, such as: lift-up device is directly well cabinet frame jacking to 3.5 meter height, the all support iron props of the strong point are just thrown off with reinforced concrete framework and floor fully so, the center of gravity that this moment, whole well cabinet frame just leaned on the sole of whole hydraulic means jacking axle to stablize the well cabinet frame entirely is not offset, in order to make the stable better of well cabinet frame, 1 imagination is now proposed, when hydraulic means during synchronously well cabinet frame jacking to 1 meter left and right, suspending jacking adopts diameter to increase with the thickening hollow bushing that the support iron prop equates the length that supports iron prop, lead screw with 0.06 meter of diameter is fixed on the termination of supporting iron prop to sleeve pipe and irony backing plate, as shown in figure " 4 ", the method purpose has 2 points, 1, make it support iron prop and increase length, be promoted in 3.5 meters height processes when supporting iron prop, the growth columnar part that supports iron prop still is enclosed within the through hole of floor, play the stabilization of the vertical jacking of well cabinet frame.2, the irony backing plate is fixed on 2 supports termination, iron prop lower end, purpose is to strengthen the intensity that supports iron prop, make other produce less deformation, the length of sleeve pipe, should decide according to the thickness that strong point reinforced concrete crossbeam adds floor, such as: crossbeam and slab thickness are 0.6 meter, 0.6 meter adds that the height that supports the iron prop lifting is 3.5 meters so, both additions should be just 4.1 meters, it is 3.35 meters because the length that supports iron prop is as the criterion with well cabinet frame lower end horizontal plane, so should being just 4.1 meters, the length of sleeve pipe deducts 3.35 meters, therefore the length of sleeve pipe should be 0.75 meter, this ejection device is mainly the stable and vertical jacking Adopts measure for the well cabinet frame, such as: when well cabinet frame jacking to the 3.5 meter height, the support iron prop of well cabinet frame still is enclosed within on floor and crossbeam, two fixing irony backing plates in iron prop termination of each strong point, jacking with the well cabinet frame rises to the distance a small amount of with the crossbeam lower end maintenance of this jacking basic point, that is to say, when producing skew as the well cabinet frame, this arranges and can play good stabilization, as: the length of sleeve design is inadequate, should increase packing ring, purpose is exactly when well cabinet frame jacking to 3.5 meter height, the irony backing plate that is fixed on support iron styletable head will keep with the crossbeam lower end horizontal plane of this jacking basic point the distance of 10 millimeter, as shown in figure " 4 ".

to exchange stressed process be that support iron capital liter is supported termination, iron prop lower end and is as the criterion can be encased inside with the irony backing plate to hydraulic means with supporting iron prop, except the casing length of connecting portion, be exactly higher than within 10 millimeters, irony backing plate, this moment, all supported the growth cylinder of iron prop still in the through hole of floor, work the stabilization of making the well cabinet frame, when the stable state of well cabinet frame, progressively stressed to each strong point exchanging one by one again, order is that incremental portion and the irony backing plate that first will support iron prop takes down, the position that irony backing plate pad is locked on crossbeam, as shown in figure " 3 ", then hydraulic means decompression, supporting iron prop falls after rise on the irony backing plate, be fixed on crossbeam and floor supporting iron prop with lead screw and stressed packing ring again, a strong point of a strong point of order is fixing according to this, hydraulic means is with regard to the decompression of a strong point of a strong point, the main purpose of the method is, support iron props all in the whole strong point are when playing stabilization, 1 fulcrum wherein exchanges stressed, not impact of stability on the well cabinet frame.

3, the disassembling method of composite set

when this building does not need this device, when removing, the first step is removed the ironware of fixing minute box, because of east, south, the west, the box on four limits, north is combined by two main boxes and 6 minutes boxes respectively, utilize thus the hoist engine on the well cabinet frame to coordinate with the movable pulley at each position, the supporting wire rope of hoist engine is stressed will divide box vertically to hang respectively toward ground in pulley brandreth car, because main box is to be locked on the i iron of well cabinet frame expenditure with the ironware hook, only need unclamp the ironware of locking during dismounting, main box just can vertically descend and hang toward ground, second step, adopt the support iron prop to coordinate with another ironware, this ironware is fixed on the crossbeam place of roof floor, the nut of the lead screw of ironware and support iron styletable head is fastening, make and support iron prop under the cooperation that flies to restrict, can become with ground line 45 degree, use thus this support iron prop to coordinate with hoist engine each parts of well cabinet frame are disassembled also handling entirely on ground, only remaining hoist engine and this support iron prop can enter and transport ground in elevator at last, annotating (connecting and composing because being specially provided with middle lead screw two joints that adopt of mast that support iron prop) so mast length disassembled is 1.8 meters, be convenient to carrying, tearing the instrument of hanging open can arrange specially, the sling little shape pedestal of substance rotating 360 degrees of employing, pedestal is fixed on roof floor and crossbeam place, position from 1 meter of exterior wall, adopt the support iron prop to coordinate with the pedestal of energy rotating 360 degrees, hoist engine is placed on the back up support body, increase again a small amount of weight and keep the support body balance, the support body back up should be in 1.8 meters to annotate (pedestal should be able to enter in elevator).
