The single-wall steel hanging box cofferdam comprises a base board and a wall board, the wall board comprises a plurality of wall board units, edges which emboss outwards are arranged on the periphery of the wall board units, adjacent wall board units are fixedly connected and pieced into the wall board on the edges through bolts, a steel bar which longitudinally penetrates through the edges is arranged outside the wall board, the top end of the steel bar is fixed with the top end of the wall board, the bottom end of the steel bar is fixed with the base board, the steel bar is tightly pulled between the wall board and the base board, the steel bar can be assembled and disassembled when in use, and the steel bar is convenient to use. The wall board and the base board are connected and fixed by pulling of the steel bar which longitudinally penetrates through the edges, the cofferdam is of box structure, the structure is stable and firm, and capacity of compression resistance, pulling resistance and distortion resistance is strong. After the cofferdam is disassembled and discomposed, the cofferdam is convenient to transport. Size of raw materials is small, special sorting is not required to manufacture, and cost is saved. The cofferdam can be used repeatedly with assembly once again, manufacturing the cofferdam is not required again, and engineering cost is reduced.
Description
Technical field
The utility model relates to a kind of space enclosing structure of subaqueous construction, particularly a kind of single-wall steel suspended box cofferdam.
Background technology
The cofferdam is in the hydraulic engineering construction, for building permanent water conservancy projects, and the provisional space enclosing structure of building.Its effect is the position of building that anti-sealing and earth enter building, so that at the cofferdam internal drainage, excavation pit is built building, generally is mainly used in the submerged structure.As in bridge construction, when bridge pier, cushion cap are positioned at the earth's surface water level when following, the dark and larger river of flow velocity at water, can build plank or steel suspended box cofferdam, it both can waterproof, enclose water, can support again the hole wall of foundation ditch, except the part as formal building, generally remove after construction is finished in the cofferdam.
Normally used steel suspended box cofferdam can be divided into two kinds in single wall formula cofferdam and double-walled cofferdam by structure, and it is more shallow that single wall formula cofferdam mainly is used in water level, and current are releived, the construction location that hydraulic pressure is less; The single wall formula cofferdam of commonly using at present, environment by construction location is processed into specific structure and profile, base plate or wallboard are generally overall structure, after using dismounting, because of the difference of different job sites environment, the cofferdam can not reuse, can only waste treatment, for different job sites, need to again open material at every turn and make new cofferdam, cause material to waste in a large number.
The utility model content
The utility model aims to provide that a kind of anti-pressure ability is strong, and dismounting is simple, reusable single-wall steel suspended box cofferdam.
Single-wall steel suspended box cofferdam described in the utility model, comprise base plate and wallboard, wallboard comprises polylith wallboard unit, the edge of the peripheral oriented outer lug of each wallboard unit, adjacent wallboard unit connects firmly by bolt in edge and pieces together the cofferdam wallboard, and the wallboard outside also is provided with vertically passes marginate reinforcing bar, and the top of described reinforcing bar and wallboard top are fixed, bottom and base plate are fixed, and tension is between wallboard and base plate.
Single-wall steel suspended box cofferdam described in the utility model, wallboard has the wallboard unit of raised brim to be put together by the polylith periphery, and adjacent wallboard unit connects firmly by bolt in edge, but field stripping and installation during use is easy to use; Wallboard and base plate vertically pass the marginate reinforcing bar tension of institute by being arranged on the wallboard outside, and cofferdam integral body is body structure, and Stability Analysis of Structures is firm, and resistance to compression, tension, anti-twist ability are strong.Simultaneously, after the cofferdam dismounting was decomposed, convenient transportation need not just can easily transport by large-scale vehicle, cost is saved in the little making of need not selecting materials especially of raw material size, and it is rear when constructing next time that the cofferdam uses dismounting, assembly unit is reusable again, need not again make cofferdam, reduce project cost.
Description of drawings
Fig. 1 part-structure schematic diagram of the present utility model.
Fig. 2 is the partial enlarged drawing at Figure 1A place.
The specific embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
Such as Fig. 1, Fig. 2 has provided a kind of single-wall steel suspended box cofferdam, it comprises base plate 1 and wallboard 2, the steel plate bolt that the periphery that wallboard is processed by specific dimensions by polylith is provided with flange is put together, adjacent steel plate is fixedly connected with by the bolt 3 that passes flange, and the whole bolt of all steel plates is assembled into the cofferdam sidewall, and wallboard vertically passes the reinforcing bar 4 of all flanges and fixes with the base plate tractive by being arranged on the wallboard outside, reinforcing bar adopts fining twisted steel to make, and wallboard and base plate are strained and fixed is body structure.
Single-wall steel suspended box cofferdam described in the utility model when constructing next time, can repeat assembly unit and use after decomposing, for different job sites, but need to add or reduce steel plate goes out to be fit to construction requirement with regard to assembly unit cofferdam by construction, need not again make cofferdam, reduce project cost.Fix by the reinforcing bar tractive that runs through wallboard flange and base plate between cofferdam wallboard and the base plate, make cofferdam integral body be body structure, compact conformation, monolithic stability is firm, the resistance to compression resistance to tension is strong, after being bolted between the wallboard in cofferdam and the base plate, fixes with the reinforcing bar tractive again, further strengthen the tension in cofferdam, anti-twist ability.
The above single-wall steel suspended box cofferdam, the reinforcing bar two ends are provided with screw thread, the reinforcing bar upper end is passed wallboard top flange and is fixed with nut 5 and wallboard, reinforcing bar passes the flange of steel plate, its lower end is passed base plate and is tightened with nut 6, with wallboard and the whole tension of base plate, the reinforcing bar two ends arrange screw thread and fix with nut, and the cofferdam is installed and decomposed simple and convenient.
The general volume in cofferdam, weight are large, install and transport extremely inconvenient, consider the configuration of crane capacity and vehicle, upper and lower two joint designs can be divided in cofferdam described in the utility model, every joint cofferdam is linked to be an integral body, top layer wallboard and bottom wallboard are put together by plurality of steel plates, be fixedly connected with by the bolt that passes the adjacent steel plate flange between top layer wallboard and the bottom wallboard, top layer wallboard, bottom wallboard and base plate are fixed to the reinforcing bar tractive of base plate by running through from top layer wallboard top flange, make cofferdam integral body be body structure.
Above-described single-wall steel suspended box cofferdam, for reducing cost, simplified structure, make installation and removal more convenient, the one meter reinforcing bar that connection top layer wallboard, bottom wallboard and a base plate are set in every interval, the cofferdam wallboard is fixedly connected with base plate, and it can satisfy the requirement of strength in cofferdam, has also reduced simultaneously to be made into.
Above-described single-wall steel suspended box cofferdam, for making the cofferdam resistance to compression, resistance to tension is stronger, overall structure is firmer, all be welded with crisscross deep floor in the steel plate outside that forms wallboard and base plate, increase the rigidity of every block plate, so that the bulk strength in cofferdam further improves, strengthen anti-twist ability.
