Abstract
The utility model relates to a large-section pressure pipeline concrete construction deformed steel formwork which is constituted by assembling a plurality of deformed steel formworks, the deformed steel formworks are mounted on arch frames, the arch frames are connected through arch frame connecting rods, and lacing bars penetrate lacing bar holes on the deformed steel formworks and are connected with the section steel arch frames. The deformed steel formworks consist of panels and ribbed plates, and clamping holes are arranged on the ribbed plates. The vertical section of each deformed steel formwork is in the shape of a circular arc. The deformed steel formworks are designed according to the structural characteristics of an upper bend section and a lower bend section of a pressure pipeline, thereby having small overall dimension deviation with the structural design and being easy to ensure the concrete appearance pouring quality; the deformed steel formworks can be connected through U-shaped clamps, thereby having convenient assembly and high turnover rate, and saving the construction cost; and a formwork support system takes the section steel arch frames as a main means and takes the lacing bars as an auxiliary means, thereby avoiding the work of assembling and disassembling a complicated load-bearing scaffold, saving the space occupied by the scaffold, solving the problem that the construction is restricted due to narrow space and accelerating the job schedule.
Description
Technical field
The utility model relates to a kind of concrete construction template, is specifically related to a kind of Special-shaped Steel Formwork that is applicable to the upper and lower curved section concrete construction of big cross-section pressure pipeline.
Background technology
The employed template of the upper and lower curved section concrete lining cutting of domestic big cross-section pressure pipeline is punching block in bulk or wooden form at present, and template assembling engineering quantity is big, work efficiency is lower, and Forming Quality is relatively poor.Because pressure pipeline is a bend pipe structure for upper and lower curved section, and is bigger as the load-bearing scaffold building difficulty of form bracing system, the restriction construction speed.
Summary of the invention
For overcoming the deficiency in the present technology, the technical problems to be solved in the utility model provides a kind of upper and lower curved section template construction that waits bend pipe structure of big cross-section pressure pipeline that be used for, template simple and convenient assembly, concrete formation are effective, the big efficiently cross-section pressure pipeline coagulation soil of the support system assembling and disassembling of bow member formula construction Special-shaped Steel Formwork.
The purpose of this utility model is achieved in that a kind of big cross-section pressure pipeline coagulation soil construction Special-shaped Steel Formwork, assembled by the polylith Special-shaped Steel Formwork, Special-shaped Steel Formwork is installed on the bow member, connect by the bow member connecting rod between the bow member, lacing wire is passed the lacing hole that is arranged on the Special-shaped Steel Formwork and is connected with the shaped steel bow member.Special-shaped Steel Formwork panel and floor are formed, and have hole clipping on the floor.The vertical cross-section of Special-shaped Steel Formwork is a circular arc.The big cross-section pressure pipeline coagulation soil construction Special-shaped Steel Formwork that the utility model provides, the design feature design that special-shaped punching block is upper and lower curved section according to pressure pipeline, little with structure design overall size deviation, the concrete appearance pouring quality is guaranteed easily; Special-shaped punching block can pass through the U-shaped card connection, and is easy to assembly, and the turnover rate height is saved construction cost; Form bracing system is based on the shaped steel bow member, and lacing wire is auxilliary, has avoided setting up, removing the work of complicated load-bearing scaffold, has saved the scaffold occupation space, solves the problem because of the narrow restriction construction in place, speeds up the work.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples: Fig. 1 is a structural front view of the present utility model; Fig. 2 is the A-A sectional view of Fig. 1; Fig. 3 is the structural plan figure of the special-shaped template of the utility model; Fig. 4 is the B-B sectional view of Fig. 3; Fig. 5 is the C-C sectional view of Fig. 3.
The specific embodiment
[0006] structure of the present utility model is as follows: a kind of big cross-section pressure pipeline coagulation soil construction Special-shaped Steel Formwork, assembled by polylith Special-shaped Steel Formwork 1, Special-shaped Steel Formwork 1 is installed on the bow member 2, connect by bow member connecting rod 3 between the bow member 2, lacing wire 4 is passed the lacing hole 9 that is arranged on the Special-shaped Steel Formwork 1 and is connected with shaped steel bow member 2.Special-shaped Steel Formwork 1 panel 5 and floor 6 are formed, and have hole clipping 7 on the floor 6.The vertical cross-section of Special-shaped Steel Formwork 1 is a circular arc.
The utility model Special-shaped Steel Formwork 1 processing method and steel form processing method in bulk are similar, and panel 5 and floor 6 adopts special equipment cold-rolling and punching global formations, and carbon dioxide gas arc welding welding, all kinds of perforates adopt machineries once or the segmentation punching.Bow member 2 adopts shaped steel to process by the bending machine merogenesis, and the two ends of every joint bow member 2 have the connecting bolt hole, by junction plate 11 and connecting bolt some nodal pattern steel bow members are connected into airtight annular.Monolithic Special-shaped Steel Formwork area is controlled at 1m
2About, the about 40Kg of weight, single-unit shaped steel bow member Weight control is about 50Kg, so that on-the-spot the installation.
When the utility model uses, set up the operation platform of easy construction scaffolding as the template installation exercise, according to order assembling Special-shaped Steel Formwork 1 from low to high, and cross that hole clipping 7 connects and temporary fixed with the U-shaped cartoon, bow member 2 and lacing wire 4 are installed then, lacing wire 4 one ends and country rock anchoring are drawn, and the other end passes the lacing hole 9 that is arranged on the Special-shaped Steel Formwork 1 and is connected with shaped steel bow member 2.After adjacent a few Pin bow member 2 installations, in time increase bow member connecting rod 3 and bow member 2 spatially is connected to integral body and carry by metal-wares such as HOOK BOLTS 8, " 3 " shape fasteners.The effect of window 10 of vibrating is to be used to vibrate concrete in the template.
Because pressure pipeline is a bend pipe structure for upper and lower curved section, spatially has rotational invariance, and Special-shaped Steel Formwork 1 and bow member 2 are according to this design feature design, each group steel form and each Pin shaped steel bow member all can use at any one upper and lower curved section position, so select the shaped steel bow member of some groups of templates and respective numbers to carry out assembly unit according to the size of position in storehouse during site operation to get final product.Treat position in storehouse build finish and reach striking time after, template and bow member removed according to the backward of erection sequence be transported to the template operation that next position in storehouse can carry out next storehouse, realize that a cover template body ties up to whole upper and lower curved section turnover and uses.
