The tank tower of segmented assembly unit
Technical field
The utility model relates to tank tower, a kind of tank tower that is particularly suited for being applied in the job site, to guarantee that construction water is pressed of more specifically saying so.
Background technology
Overwhelming majority engineering construction is to construct in the open air; One big difference of field construction and municipal construction is to adopt city tap-water to supply water when being municipal construction; And field construction need be dug place's well at the scene; From well, draw water to the water supply water tower, need keep the certain hydraulic pressure of water in the water tower simultaneously.
In the prior art, be applied in the water tower in the engineering construction, its tank tower normally adopts concrete foundation and full masonry walls body, and there is following problem in this form of structure in practice of construction:
1, the work progress of full masonry walls body comprises: basic formwork erection, base concrete construction and pre-buried wall body connecting reinforcement, concrete curing, form removal, segmentation masonry wall body, water tank base are set up etc.; Manufacturing process takes a lot of work, time-consuming; Cycle is long, and masonry walls body verticality is difficult to control;
2, full masonry walls dismantle big, cost of dismantling and freight height in man-hour when the later stage reclaims in the place;
3, masonry walls body construction quality is difficult to control, and wall body building construction causes structural stability poor after too high, has great potential safety hazard.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of tank tower of segmented assembly unit being provided, to simplify work progress, useless, the increase structural stability of the raw-material consumption of minimizing.
The utility model technical solution problem adopts following technical scheme:
The design feature of the tank tower of the segmented assembly unit of the utility model is: the pre-embedded steel slab composite member constitutes tower foundation in the concrete foundation of bottom; Be arranged on pylon body on the tower foundation and be by each pylon standard knot of Steel Space Truss structure along assembled on the height of pylon; Tower top is provided with a water tank base, and water tank is placed on the said water tank base.
The design feature of the tank tower of the segmented assembly unit of the utility model also is:
Said pylon standard knot comprises bottom standard knot, intermediate layer standard knot and top layer standard knot, said bottom standard knot) be to be connected with pre-embedded steel slab composite member flange in its Steel Space Truss central post and the bottom concrete foundation; Be to adopt flange to connect between the column in the Steel Space Truss on relative position between the pylon standard knot of adjacent one deck; Said top layer standard knot is to be connected with flange between its space truss central post and the water tank base.
The pylon standard knot of said Steel Space Truss structure is the integral solder structure.
Said water tank base is a truss structural.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model adopts the steel truss splicing structure, has simplified production process greatly, and quick construction is convenient, effectively the reduction of erection time; Its tank tower, each standard knot and water tank base can be reused, and have avoided waste.
2, the utility model adopts flange to connect sound construction, easy accessibility.
3, the utility model through adjustment tank tower assembly unit quantity reach adjustment water tower height purpose, simple and convenient, Practical Performance is high.
4, the whole steel truss structure of the utility model has good rigidity and stability
5, the utility model can adopt batch production processing, and single member maximum length is no more than 6m, convenient transportation basically.
Description of drawings
Fig. 1 is the utility model structural representation;
Label among the figure: 1 concrete foundation; 2 pre-embedded steel slab composite membeies; 3 pylon standard knots; 31 bottom standard knots; 32 intermediate layer standard knots; 33 top layer standard knots; 4 water tank bases; 5 water tanks.
The specific embodiment
Referring to Fig. 1; Tank tower is that pre-embedded steel slab composite member 2 constitutes tower foundation in bottom concrete foundation 1 in the present embodiment; Be arranged on pylon body on the tower foundation and be by each pylon standard knot 3 of Steel Space Truss structure along assembled on the height of pylon; Tower top is provided with a water tank base 4, and water tank 5 is placed on the water tank base 4.
In the practical implementation, as shown in Figure 1, each pylon standard knot 3 comprises bottom standard knot 31, intermediate layer standard knot 32 and top layer standard knot 33, and bottom standard knot 31 is to be connected with pre-embedded steel slab composite member 2 flanges in its Steel Space Truss central post and the bottom concrete foundation 1; Be to adopt flange to connect between the column in the Steel Space Truss on relative position between the pylon standard knot of adjacent one deck; Top layer standard knot 33 is to be connected with flange between its space truss central post and the water tank base 4, and the form that flange connects makes disassembly process more convenient.
Be the firm degree of an assurance total, the pylon standard knot 3 of Steel Space Truss structure adopts the integral solder structures, and the height of each pylon standard knot is set to 3.5m, and water tank base 4 is a truss structural.
Work progress:
1, at first presses the construction that usual manner is accomplished water tower concrete foundation 1; And in water tower basis 1, pre-embedded steel slab composite member 2 is set; When construction, wrapped up the bolt silk mouth of pre-embedded steel slab composite member 2; And the planeness of the steel plate on the requirement assurance pre-embedded steel slab composite member 2, four jiaos of discrepancy in elevation must not be greater than 2mm;
2, adopt the bolt double nut of M20 to fix between pre-embedded steel slab composite member 2 and the bottom standard knot 31, and by joint intermediate layer standard knot 32 and top layer standard knot 33 are installed from lower to upper, water tank base 4 is installed at top layer standard knot 33;
3, on lifting water tank 5 to the water tank base 4, water tank is installed firmly and is promptly accomplished.
