Steel bar preassembling is made independently individual reinforced mesh on ground, re-use tower crane reinforced mesh is risen winch to assigned address install, and the mesh sheet after installing effectively is reinforced, until all reinforced mesh form entirety, under the premise that security is guaranteed, financial cost can be reduced, promote workmanship, improve construction efficiency.
Accompanying drawing explanation
The above and other features of the present invention, character and advantage become more obvious by passing through below in conjunction with the description of drawings and Examples, wherein:
Fig. 1 is the prefabricated operation drawing of the reinforced mesh of one embodiment of the invention.
Fig. 2 is the hoisting steel mesh piece schematic diagram of one embodiment of the invention.
Fig. 3 is that the reinforced mesh of one embodiment of the invention installs reinforcing figure.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the invention will be further described; set forth more details in the following description so that fully understand the present invention; but the present invention obviously can implement with multiple this alternate manner described that is different from; those skilled in the art when doing similar popularization, deduction without prejudice to when intension of the present invention according to practical situations, therefore should can not limit the scope of the invention with the content of this specific embodiment.
Below for the construction of a storage tank concrete outer tank body of wall, its top mark height 40.085m, internal diameter R=41.000m, external diameter R=41.800m, thickness 0.800m.In body of wall, outside is φ 20 200 double layer bar about 1000t altogether, adopts construction in layer, amounts to 11 layers, builds highly about 3.7m for every layer.
In typical floor, outside reinforced mesh adopts 2 to build highly to add 1 bar splicing and highly carries out prefabricated, lifting and installation so that on-the-spot interior outside reinforced mesh hockets, interior outside mesh sheet differs 1 floor height, and medial and lateral mesh sheet fabricate block situation as shown in Table 1.
Table one: reinforced mesh fabricate block table (in table, CJ01-CJ11 is the construction number of plies that design drawing is determined)
The precast construction of reinforced mesh 100 as shown in Figure 1, process in preform region by reinforced mesh, and adopt tied silk 3 to carry out colligation, mesh sheet surrounding two placing of reinforcement mesh sheet and suspension centre two rows can adopt different tied silks to carry out colligation reinforcing.Suspension centre is generally located on layer 5 horizontal reinforcement, and mesh sheet is totally five suspension centres, and a middle suspension centre is arranged on the vertical center of gravity direction of mesh sheet, ensures the stability of mesh sheet in lifting process.
In hoisting steel mesh piece process, for preventing the distortion of suspension centre place reinforcing bar, can tie up pricking place increases U-shaped card 2 strengthen on suspension centre both sides, guarantees that suspension centre is firm, or adopts steel-bar arrangement bridging 4, ensure that reinforced mesh has enough rigidity in hoisting process.
Carry out examination when reinforced mesh first time lifting to hang, after mesh sheet slings liftoff about 1m height, keep mesh sheet static 3 minutes.If reinforced mesh is without distortion, reinforcing bar then can proceed lifting without obscission; If mesh sheet goes wrong when examination is hung, reinforced mesh should be reinforced again, and then examination is hung, until meet the requirements.
As depicted in figs. 1 and 2, adopt on-the-spot tower crane 5 to promote reinforced mesh at suspension centre place, along the slow handling of camber line to the front upper place of installation site, and then light and slow put into final riding position.The hook wire rope of on-the-spot tower crane 5, balance hanging beam 1 held again by wire rope, and balance hanging beam 1 is connected with the suspension centre of reinforced mesh 100 by multiple wire rope.
For preventing the shifted laterally of bar construction, the interlaced reinforcing bar of tank skin part will be placed on left side or the right side of below reserved joint bar according to the mode of regulation.
During installation, reinforced mesh winches to behind the top of holding position, slowly reduces the height of reinforced mesh, is down to after appointment lap position, carries out colligation connection until reinforced mesh.
Colligation lap joint staggers by design drawing requirement, colligation lap length must meet the overlap joint multiple of design drawing requirement, and lap position place tied silk is no less than five roads (together middle, each twice in both sides), all overlap joint colligations must be firm, to ensure verticality and the radius of mesh sheet.If conflict mutually with other built-in fitting and sleeve pipe in the position of reinforcing bar, then this reinforcing bar should do dislocation adjustment (bending or anchoring after disconnecting), pays the utmost attention to built-in fitting and prestressed casing position.
As shown in Figure 3, the upper end of reinforced mesh is connected with opposite side reinforced mesh with 101 tension ribs, to control the spacing of mouth inner and outer side reinforced mesh on concrete lift, along the circumferential direction arranges together every a segment distance.Interior outside reinforced mesh arranges tension rib 101 by drawing and is no less than 3 rows.Directly colligation is on vertical reinforcement for wall tie bar 101, and as collided with bellows, radial direction suitably adjusts.
Each uniform 4 road wind resistance drawstrings 102 on both sides, reinforced mesh height 1/3 place, wind resistance drawstring 102 is connected with template platform 103 root to be strained.
After the complete and wind resistance drawstring of the whole colligation of reinforced mesh lap position is reinforced, remove suspension hook.
By tied silk colligation concrete pad 105 outside reinforced mesh, concrete pad thickness equals tank wall thickness of concrete cover.
Previous embodiment tool has the following advantages:
Duration is short: carry out prefabricated in advance when carrying out template assembly and concreting, adopts reinforced mesh modular construction, improves operating efficiency, facilitate construction speed.
Quality advance: because reinforced mesh carries out prefabricated on precasting yard ground, colligation is convenient, improves the colligation quality of reinforced mesh.
Safety improves: decrease a large amount of work high above the ground work amounts, avoid bulk deposition reinforcing bar on job platform, further ensure that the security reliability of operation.
Construction costs is low: the reinforcing bar tower amount of connecing reduces, avoid scaffolding steel pipe to transport, take and tear open, and labour drops into minimizing, duration shortening, and construction costs is reduced.
Although the present invention with preferred embodiment openly as above, it is not that any those skilled in the art without departing from the spirit and scope of the present invention, can make possible variation and amendment for limiting the present invention.Therefore, every content not departing from technical solution of the present invention, any amendment done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all fall within protection domain that the claims in the present invention define.
