Abstract
The utility model relates to the field of construction of a vertical water stop of a tunnel inverted arch, and particularly relates to a vertical buried type water stop clamp of an inverted arch, solving the problems that the existing vertical type water stop of the inverted arch mostly adopts a steel bar clip to fix, the construction cost is high, the appearance quality of the water stop is poor and the like. The vertical buried type water stop clamp comprises two long-strip-shaped positioning clamping plates which are movably spliced together; one ends of the long-strip-shaped positioning clamping plates are placed on an inverted arch surface and the other ends of the long-strip-shaped positioning clamping plates are fixed with a mould clamping groove of the inverted arch end; reversed type U-shaped clips are arranged above the two long-strip-shaped positioning clamping plates at intervals; the outer sides of the two long-strip-shaped positioning clamping plates are provided with positioning nuts with inner screw threads; and positioning bolts for ejecting the long-strip-shaped positioning clamping plates are arranged in the positioning nuts in a penetrating manner. According to the vertical buried type water stop clamp, the structure is simple, the design is reasonable, the construction is simple and convenient, the displacement in the construction process of the water stop due to the insufficient rigidity of steel bars can be avoided effectively, the installation quality of the vertical buried type water stop of the inverted arch is improved, and meanwhile, the investment of a large quantity of the steel bars is saved, the engineering cost is reduced and the popularization value is high.
Description
Technical field
The utility model relates to the vertical waterstop construction field of tunnel invert, is specially the vertically middle buried water stop anchor clamps of a kind of inverted arch.
Background technology
At present, the vertical waterstop of tunnel invert adopts reinforcing bar to stick into row mostly and fixes, and the reinforcing bar card adopts Φ 22 longitudinal reinforcements that waterstop is clamped and positions; Φ 8 vertical reinforcements or iron wire are assisted reinforcing, and spacing 40cm helps waterstop upright; Because the waterstop absolute altitude also has 30cm apart from the inverted arch bottom; So handling reinforcement must be set reinforcing bar is carried out bracing reinforcement, handling reinforcement adopts Φ 22 reinforcing bars, spacing 100cm.Owing to the reinforcing bar insufficient rigidity, waterstop causes the waterstop off normal often by concrete crimp, positioning in the fluid concrete process in the practice of construction, and straight inadequately, stagnant water effect is poor.Carry out Prevention Processing though in subsequent operation, this phenomenon is encrypted support, effect is not too obvious.Also just therefore having caused the inverted arch construction to go up construction costs increases, and vertically the waterstop presentation quality is poor, crooked, not straight phenomenon is serious.
Summary of the invention
To adopt reinforcing bar to stick into row mostly fixing in order to solve the existing vertical waterstop of inverted arch for the utility model, has problems such as construction costs height, waterstop presentation quality difference, provides a kind of inverted arch vertically middle buried water stop anchor clamps
The utility model is to adopt following technical scheme to realize: the vertically middle buried water stop anchor clamps of inverted arch; The vertically middle buried water stop anchor clamps of inverted arch; The strip positioning splint that it is characterized in that comprising that an end is placed on the inverted arch face, the other end and two fixing activities of inverted arch end mould draw-in groove is bolted together; Two strip positioning splint laying inversion type spaced above U type cards; The positioning bolt that is provided for holding out against the strip positioning splint is run through in U type card both sides and be positioned at the positioning screw cap that two strip positioning splint arranged outside have screw thread in the positioning screw cap.The quantity of said inversion type U type card is confirmed according to the length of strip positioning splint.Adopt the structure design of the utility model, can waterstop tightly be clamped between two strip positioning splints, play positioning action, guarantee that waterstop is straight, and off normal can not take place through inversion type U type card and bolt, positioning screw cap.
Because concrete flowability in the process of building is bigger, for fear of positioning splint and waterstop generation off normal, the described strip positioning splint of the utility model cross section is the L type, can increase its intensity, in practice of construction, can adopt the angle steel of job site.
The internal vertex of said inversion type U type card is the half the of waterstop height to the distance of its bottom end points; Usually in construction, the waterstop absolute altitude also has a segment distance apart from the inverted arch bottom, like this; The workman when mounted; As long as the internal vertex of inversion type U type card is withstood at the waterstop top, can guarantee that the waterstop bottom just in time contacts after waterstop and anchor clamps thereof place bottom inverted arch.
Compared with prior art; The utility model is simple in structure, reasonable in design, easy construction; Effectively avoided because the reinforcing bar insufficient rigidity causes the displacement in the waterstop work progress, improved the installation quality of the vertically middle buried water stop of inverted arch, saved a large amount of reinforcing bar inputs simultaneously; Reduced engineering cost, higher promotional value has been arranged.
Description of drawings
Fig. 1 is the vertical structure sketch map of the utility model;
Fig. 2 is the cross-sectional configuration sketch map of the utility model;
Among the figure: 1,2-strip positioning splint; 3-U type card; The 4-bolt; The 5-waterstop; The 6-positioning screw cap.
The specific embodiment
The vertically middle buried water stop anchor clamps of inverted arch; As shown in Figure 1; The strip positioning splint 1,2 that comprise that an end is placed on the inverted arch face, the other end and two fixing activities of inverted arch end mould draw-in groove is bolted together; Strip positioning splint cross section is the L type, can adopt the angle steel of job site, two strip positioning splint laying inversion type spaced above U type cards 3; The positioning bolt 4 that is provided for holding out against the strip positioning splint is run through in U type card both sides and be positioned at the positioning screw cap 6 that two strip positioning splint arranged outside have screw thread in the positioning screw cap.
During construction, adopt two angle steel that waterstop is clamped, waterstop 15cm is reserved in the angle steel below; Then inversion type U type is buckled on two angle steel, and makes the waterstop top just in time withstand the internal vertex of inversion type U type card, the height that this moment, waterstop was positioned at U type card is 15cm; Tighten the positioning bolt of U type card both sides then, make its front end tightly withstand corresponding strip positioning splint, being fixedly clamped at the waterstop between two strip positioning splints; Carrying out anchor clamps by design elevation then lays; Anchor clamps one end is placed on the inverted arch face of having constructed, and the other end utilizes inverted arch end mould draw-in groove to fix, and so just vertical waterstop is fixedly positioning; As long as note a little vibrating, the waterstop positioning fixture just can not displacement during fluid concrete.
