The detailed introduction of embodiment
The present invention has utilized the prefabricated unit that forms on ground line to build the high-rise building with many floors.For this process clearly is described, introduce the step that is used to build representational 40 one storey buildings of system according to the invention below with reference to the accompanying drawings.
In Fig. 1, this representational 40 one storey buildings have been shown with complete form, it comprises general bottom 2,39 layers of live layer or floor building on bottom, and the half storey 4 that is used for the 41st floor, it is by occupied with several large-scale fire prevention reservoirs and piping facility between lift facility.Each floor has core 6 and four inhabitation side buildings 8, and core 6 has six elevator ﹠ stairs and multiple facility.Each side building is occupied by the quadruplet apartment that has one to three bedroom.The building of this example has 624 cover unit, apartment altogether.
Though this representational building has four side buildings and a core, yet system according to the present invention can be used for building the building that has more or less side building.Core also can not be a necessary part of design.The major requirement of using this system is that each floor can form by the substantially the same unit composition that will form on ground line together.Therefore, can change the apartment tricks, apartment layout, elevator quantity and other building detail and still belong in the scope of the present invention.To introduce this system by its continuous step below.
Step 1, the on-the-spot preparation
The construction of building starts from on-the-spot the preparation.Can prepare the place by utility company and ground subcontractor, comprise for example ground of construction of buildings.Ground is made of thick mat foundation usually, and it need be supported by stake in the mellow soil or boring vertical shaft.In this step, also need usually underground installation connector installation in position.If have side building 8 and core 6, in this stage, should form their ground so.
Step 2 is installed essence and is examined template
Next step according to this representative embodiment of the present invention is that the accurate template that is used to make Prefabricated block is installed.Between the side building of building, build and four the large-sized concrete work plates 10 that are shaped, as shown in Figure 2.When working plate 10 solidifies, the accurate template of eight precast concretes is installed on these large-sized concrete plates 10, for example quantity is respectively two accurate template A, B, C and D.With the module of four maximums (the heaviest), promptly two A and two B are placed on the nearest position of decentre part 6, so that reduce the required hoisting power of the self-raising tower gantry crane that is arranged on the center.The size of accurate template and quantity depend on the size that the required Prefabricated block of each flooring of building is installed.In a preferred embodiment, accurate template has can remain on concrete the fastening position of required form till it solidifies, and is convenient to take out the Prefabricated block that is shaped and module is placed on open position in the fabric structure by stages or directly from accurate template.
Step 3 is built the core that is used for first and second floor and the concrete in side building
To be used for the concreting in core 6 and four side buildings 8 of first and second floor below.The work in this stage from one 104 tons self-raising tower gantry crane 20 is installed, bolt is tight and be supported on first floor the central area plate the center and.The self-raising tower gantry crane for example can rise to the weight up to 52 tons 27.4 meters.
The structure that forms first floor (ground floor) and extend vertically up to second floor adopts conventional method to build, and this is because this floor is higher and different with the layout of 39 layers of layer of living of top.Ground floor generally includes bigger rest room and entrance hall, bigger canyon and other structure that is not provided with in other layer.In this step, adopt concreting to set up and support the vertical shear wall 22 that is used for side building 8 and core 6, as shown in Figure 3.
When the vertical shear wall 22 of center part and support column 24 solidify, unsettled mould of requisite number purpose (flying-form table) 26 is installed, between these structural element so that be used for the building of second floor 27 of core 6, as shown in Figure 4.Also should pour into a mould the floor 30 of the remainder in second layer side building 8, so that provide support for subsequently floor.
Follow hard on building of second floor 27 and should prepare second to the 3rd layer center shear wall 28 afterwards, and build as soon as possible.Reserve elevator hall's plate of placing tower gantry crane in current cast, it will seal by second pouring in the future.According to a preferred embodiment of the present invention, if be provided with core, can adopt various conventional arts or method and build whole core 6 in a conventional manner.Because core comprises the vertical openings that is used for stair and elevator shaft, so it can not ideally adopt modularization Prefabricated block of the present invention to build.Yet core 6 also can adopt Prefabricated block to build.
As a rule, the construction of core 6 can be carried out before about two or three layers of the floor that Prefabricated block is set.Can adopt any suitable construction method to build core 6.For example, if adopted unsettled mould 26, flooring that so can estimated center part 6 is built needs three days cycle.The cycle of this core becomes the limiting factor how soon the decision building can build up.
In case second layer central plate 27 is poured into a mould, just unsettled mould 26 moved to the top of second layer central plate 27, so that prepare to carry out the 3rd layer cast.The concrete of the 3rd layer of not shown central plate is to adopt unsettled mould 26 to build with second layer central plate 27 similar methods.Because unsettled mould 26 is with vertical support column 24 and/or shear wall links to each other rather than link to each other with the flooring of front, therefore needn't wait for floor curing before pouring into a mould follow-up flooring.In a preferred embodiment, on the extensile jack that unsettled mould 26 can be installed in support column 24 and/or shear wall link to each other, so that when having poured into a mould floor, pull down unsettled mould.
When forming floors with unsettled mould 26, can on ground line, prepare the accurate template that is used to build Prefabricated block 31, in case accurate template A, B, C and D are ready, just can begin to carry out the first eight individual prefabricated precision form module preparation and build.In different embodiment according to the subject invention, can form number according to architectural design is to be different from eight Prefabricated block.
Step 4, the preparation of the module of first group of prefabricated precision form and build circulation
All can produce a module 31 each every day in eight accurate templates.Each module 31 can be different type (for example per two by accurate template A, B, C and D make), and has the full-time staff to carry out following work, preferably carries out to the middle period in afternoon in the morning.These work are designed to can be formation Prefabricated block 31 and prepare accurate template, in case the ready Prefabricated block 31 of just building of template.These work comprise:
A) surface and the parts to accurate template clean, lubricate and coating mold oil, and accurate template is maintained;
B) the fixedly pre-buried wooden unit of shipboard, check panelling and/or wall bone bar (studstrip) on template, so that concrete flowing, it is described to see below;
C) fixed gate window frame on the exterior wall of template center is provided with the closed post of mild steel or the junction plate 51 of cast on doorframe, thereby for module provides torsional rigidity, as shown in Figure 6;
D) gauze wire cloth and reinforcing bar are placed and be fixed in the inside center and the opening between the outside rollback template cover on the template;
E) securing electric lines, block terminal and other inclusion;
F) before closed, check and the parts checking and approving or proofread and correct in the accurate template assemble;
G) for example with intensity at about f c'=4000 pound/square inch and f cConcrete between '=6000 pound/square inch comes closed and formwork for placing;
H) apply vibration and repair and help concrete flow;
I) make concrete curing, in that day subsequently, obtain for example about f cThe demoulding strength of '=2800 pound/square inch;
J) open template, template is cleaned, embrocates and sprays with curing agent;
K) finish, seal and test window;
L) just check and take out each Prefabricated block 31 if check and approve;
M) with pillar crane 20 Prefabricated block 31 is risen to effective floor.
The above-mentioned work of carrying out is representational.The particular order and the necessity of each work can change according to the particular requirement of construction structure.Prefabricated block can have five surfaces shown in the example of Fig. 4, for example four sides 33 and an end face 64.
Because preparation of the major part of Prefabricated block 31 and work for inspection are finished on ground line, so the workman can operate under safer environment, and the while of more effectively working can obtain the final finished of high-quality.Work for inspection is also easier and can more fully carry out, and this just makes the quality of building increase.It is also important that, compare with other possible mode, build carry out sooner and cost lower.
Step 5 is placed on module C and D on the second layer floor.
Being promoted first module that puts in place by gantry crane 20 is two C modules and two D modules, and they are placed on as shown in Figure 5 the position.These modules have occupied the end in side building.Adopt construction laser measurement point 35 to control the accurate placement of the accurate module 31 that tower gantry crane 20 carried out.Accurately the number of location and survey mark 35 can change according to the particular design of building.In addition, main construction control points 36 can be set, as shown in Figure 5 at each external angle with building.
Each Prefabricated block can be provided with special reinforcement pillar 38 at main construction control points 36 places.The purpose of these pillars 38 is to prevent to form tension force in these outermost points of limit wind action lower edge structure.Each pillar 38 can have Embedded hollow tube 40, is provided with the dowel 42 of high strength steel in pipe.For example, dowel 42 can be that screwed diameter is 1.25 inches the rod iron that hardens.When each Prefabricated block 31 descends when in place lentamente, dowel 42 for example links to each other by the dowel of mechanical type screw shell with the corresponding align of exposing from the floor of the below floor that forms in front.
Available post-tensioned tendon obtains other form or extra tension.In the situation of building the second layer, the post-tensioning anchorage that the fixed end anchoring piece is fixed in first floor is put 44 places, it is similar to as shown in Figure 6.Tendon provides can be with the flooring tension vertical tension together at external angle place.Carrying out along with building carries out stretch-draw at each new flooring place.
For building acts and natural conditions is not too harsh application scenario, can save pillar 38 and tendon.Pillar and tendon can be together or individually for the completion building provides added strength, the side loading that is brought by earthquake, hurricane and other phenomenon with opposing.
Each module C and D are designed to be formed with opening 50 along their shear wall 33, as shown in Figure 6.These openings 50 are also referred to as " gunnel ", and this is because they are similar to being used for of using in ship water to be discharged structure outside the deck.The purpose of these gunnels 50 is that concrete is flowed freely by shear wall 33 between all modules of each flooring.For example, in case can form the equal placed in position of all Prefabricated blocks of a flooring in side building 8, so just on this flooring, pour into a mould the surface concrete membrane cross wall, Prefabricated block is bonded on the public flooring.Gunnel 50 allows concrete to flow freely between all modules in side building 8.In most of the cases this is an once-cast, and it is designed to and all side buildings and core can be linked together, rather than once-cast only covers a side building.In addition, gunnel size and position are decided by specific building design.
Another feature of in each module C and D, using be to use as shown in Figure 8 wall and the check structure 53 of flooring.These hackly surfaces or check structure 53 are arranged to and the shear wall 33 of all modules of each flooring can be locked together with floor cover 30.Can be by come on shear wall 33, to realize the effect of check at the grid that forms vertical rib or vertical and level on the shell of accurate template.The pressure that can strengthen between these different components by these mechanical interlocking structures flows.
In Fig. 6, shown another kind of mutual interlocking gear.Interior wall 33 and top board in each module 31 upper edge module are provided with wall bone bar 52.These wall bone bars 52 be used for the module that each is continuous and placed in position all the other construction machines fasten.Therefore wall bone bar 52 for example can be fixed on the floor 30 that forms with the lower floor in front, can form firmer being connected of Prefabricated block and floor 30 after the surface concrete membrane cast.The function of wall bone bar 52 is identical with the function on above-mentioned check surface.
Except that the check structure 53 and wall bone bar 52 of wall and flooring, can also adopt the interlock fit part of other known type to strengthen connection between shear wall 33 and the floor 30.
Step 6, on second layer floor with modules A and B placed in position
In case Prefabricated block C and D are in place, just by promoting Prefabricated block A and B and make it in place to above-mentioned similar process.The same with module C and D, Prefabricated block A and B can prepare when producing accurate template continuously.Modules A and B are placed on the inboard of module C and D, shown in Fig. 5 and 7.Prefabricated block A and B by public shear wall 60 with central area 6 adjacency.Only after from second layer floor, having taken out unsettled the mould 26 that is used to build core 6, just can form the modules A and the B placed in position of the second layer, and the floor above in the cast preparation of the 3rd floor plate, moving to them more.
Step 7 is with second group of eight module placed in position
All side buildings 8 to building carry out identical process.Form Prefabricated block A as required, B, C and D, and prepare when ready the appropriate position that it is moved on the second layer floor 30 at them.For each side building 8, first placement module C and D, placement module A and B then.
When on second layer floor 30 with Prefabricated block A, B when C and D placed in position, has reserved the space of opening wide 62, as shown in Figure 7 between the prefabricated vertical shear wall 33 of module.To in subsequent step as described below, fill these spaces 62, so that strengthen the intensity of structure.
Step 8 is built the surface concrete membrane cross wall that is used for second layer floor
In case with all Prefabricated block A, B, C and D placed in position, so whole assembly just can bear building of cover or cross wall.Whole second layer floor 30 can bear concrete one-time-concreting, and it can surround core 6 and four side buildings 8.Gunnel 50 along string setting in the bottom of all module walls allows concrete freely to flow in the process of building, as mentioned above.Like this, concrete just can form the Prefabricated block in all side buildings 8 of whole flooring and strain together, and also link together with core 6.According to suitable building acts, can add reinforced concrete by structural iron reinforcing bar or gauze wire cloth and/or steel wire fence.For example, can realize the accurate lining of fluid concrete by adopting common laser light reference beam as survey tool.
In a preferred embodiment, being used to of using at the door opening place increases the height of junction plate 51 of torsional rigidity of Prefabricated block 31 and the deep equality of fluid concrete cross wall.This has just guaranteed that the completion unit has smooth flooring, and has guaranteed to form the firm anchoring of all Prefabricated blocks 31 of a floor.
For all Prefabricated blocks tension in core 6 and side building 8 is in the same place, the post-tensioned tendon that embeds of the posttension fixed point 44 places anchoring of module C and D externally, its beginning passes the below of modules A and B and enters into center shear wall 60.The position of typical posttension pillar for example can be positioned at the inside of elevator shaft wall (its for example be 10 inches thick).Tendon provides Horizontal Tension between core 6 and side building 8.
When the surface concrete membrane cross wall hardens to f c' 70% o'clock, post-tensioned tendon is compacted usually.Tendon for example can be loaded in the flexible metallic hose, and described pipe is filled to protect tendon can not corrode by grout after stretching.Because pressure is relevant with the time, so reinforcing bar and surface concrete membrane meeting generation plastic strain under the pressure that continues.Can be by using high-intensity concrete and using water reducing admixture (superplasticizer) and slag to compensate the concrete shrinkage that causes because of moisture loss.Steel is to have stable high-intensity type, can reduce stress relaxation significantly.
The posttension step is a selectable step.Therefore, when building need have extra intensity, can adopt this step when for example being in the active area of earthquake, and in using, other can omit this step.
Step 9 is used for the variation of the outer cover process of the second layer other layer in addition
All modules 31 that form in accurate template have the top board 64 of an integral body.This top board 64 has the thickness between about 4 inches to 5 inches usually, and it is as watering " template " that outpours as the described cover of step 8 thereon.Therefore in order to reduce required intensity and to alleviate the weight of Prefabricated block, and eliminate the top board deflection that in the outer cover process, produces, can before building the cover concrete, provisional pillar be set at the key position place.
In a preferred embodiment, can carry out the finite element analysis of structure to module, thus the expection deflection of all parts in the predict.Can place provisional pillar exactly about the understanding of deflection is feasible.
Step 10 promotes tower gantry crane
According to a preferred embodiment of the present invention, when building second layer floor in above-mentioned steps 8 and 9, the full-time staff can rise to the 4th floor with center shear wall 28, and the 3rd layer of similar center floor of formation and second layer center floor 27.Then tower gantry crane 20 upwards is repositioned onto a top floor, and bolt is tightly on the elevator shear wall between second and the 3rd layer of center floor.
In another embodiment, if adopted sufficiently high tower sliding metal pipeline, so only need tower gantry crane 20 is risen on the tenth flooring from per the 6th flooring, thereby saved artificial and time.
Step 11, the circulation that replicated blocks are placed, the construction of building cover and core pushes away Advance
The circulation of repetition aforesaid operations, number of repetition and floor yet to be built are as many.In the representative embodiment of above-mentioned building, this process lasts till the 40th layer.If the 41st layer different with the layer of living, build the 41st layer so in a conventional manner.
As mentioned above, with modules A, B, C and D are placed on the floor of current flooring, make to reserve unlimited space 62 between vertical dry wall 33, as described in Figure 7.When building the surface concrete membrane of the flooring that is used for each continuous floor, flow in these spaces 62 of the lower floor that concrete is also formerly finished.Therefore just filled space 62 with concrete, with Prefabricated block A, B, C and D are bonded together, and have improved the intensity of structure significantly.
In a preferred embodiment, the step in the space 62 between the vertical wall 33 of filling Prefabricated block 31 can be the independent step of independently carrying out with the cross wall cover of pouring into a mould continuous flooring.This step forms the interior shear wall in structural crucial side building 8, and helps to improve the maximum intensity of the structure of finishing.This step can typically be carried out before the concrete cross wall of flooring above the cast.
The method that is used to build high-rise building according to the present invention is that structure has been brought many great improvement.For example, the method can be built firmer building, can resist the side load that brings because of strong wind and seismic activity, and have less laterally offset under wind load.Building has the vibration natural frequency of reduction and helps the higher critical damping of antidetonation.
Other advantage of the method according to this invention is to shorten time of completion and condition of work is safer, can finish first floor in for example per three days, and conventional method needs five to ten days.For example, this method has been eliminated the demand to outside scaffolding, and this is because exterior wall, window seals, prime, japanning and most of other construction and work for inspection can be carried out on ground line.
From material still less expend, lower rate of premium, safer condition of work, lower accident rate and can realize significant cost savings the time of completion faster.Compare with conventional method, can realize higher-quality construction, this is because the workman finishes all basically work on ground line, and checks on the quality and the management personnel that directly proofread and correct also carry out work on ground line.The precision of carrying out on ground line is built can be for each model forms very accurate dimensions and surface, and this is because each model is the mechanical reproduction part of other model.Only need adjustment seldom or do not need just to adjust to realize suitable fine finishining.
For a person skilled in the art clearly, under the prerequisite that does not break away from the spirit or scope of the present invention, can carry out various modifications and variations to structure of the present invention or method.Therefore, the present invention is intended to cover the modifications and variations of the present invention in the scope that belongs to claims and equivalent thereof.
