Description

Utility tunnel unilateral formwork reinforcement

Technical Field

The utility model relates to a building technical field specifically relates to a utility tunnel unilateral formwork reinforcement.

Background

Traditional city utility tunnel unilateral formwork construction mainly uses the lateral pressure that the concrete was resisted to the wall stagnant water screw rod that passes through of syllogic in template inside, and the concrete lateral pressure is resisted to outside mainly using steel pipe bent frame support back of the body stupefied, fossil fragments. When the three-section type wall-through water-stopping screw rod used in the construction method is installed, one end of the water-stopping screw rod is cut off, the other end without the rubber sleeve of the rest part is welded on the main rib to enable the main rib to bear force, and a large amount of transverse supports resisting the lateral pressure of concrete are additionally arranged when a steel pipe bent frame formwork support system is erected; when the construction method is adopted for construction, a large number of through-wall water stop screws can be intercepted, so that material waste is caused; and unnecessary construction cost can be increased and the construction period can be prolonged when the steel pipe bent frame is erected.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings.

As shown in fig. 1-2, the utility model discloses utility tunnel unilateral formwork reinforcement of embodiment, including screw rod 4, locator card 1, water stop 2, cone nut 3, butterfly card 5, lock nut 6, locator card 1 includes straight-bar 11 and two jack catchs 12 connected with straight-bar 11, straight-bar 11 is connected with screw rod 4; the water stop sheet 2 is fixed on the straight rod 11 and positioned between the two clamping jaws 12; the cone nut 3 and the locking nut 6 are both connected with the screw rod 4 in a screwing mode, and the butterfly card 5 is sleeved on the screw rod 4 and located between the cone nut 3 and the locking nut 6.

The butterfly card 5 comprises a base 51 with a hole and two clamping groups which are symmetrically arranged, each clamping group comprises a sliding rod 52, a sliding sleeve 53, a spring 54, a clamping hook 55 and a baffle 56, one end of each sliding rod 52 is fixedly connected with the base 51, the other end of each sliding rod is fixedly connected with the baffle 56, the sliding sleeve 53 is fixedly connected with the clamping hook 55, the sliding sleeve 53 is slidably connected with the sliding rod 52, and the spring 54 is sleeved on the sliding rod 52 and extruded between the sliding sleeve 53 and the baffle 56; the base 51 is sleeved on the straight rod 11.
