Abstract
The utility model discloses a processing structure for a gap between concrete prefabricated beams. The processing structure comprises the gap between the concrete prefabricated beams, a reverse hoisting formwork and a micro-expansive cement mortar backfill body, wherein the reverse hoisting formwork is detachably installed at the bottom of the gap, and the micro-expansive cement mortar backfill body is located in the gap. The processing structure for the gap between the concrete prefabricated beams has the advantages that due to the fact that the reverse hoisting formwork which is detachably installed serves as a construction formwork for concrete prefabricated beam gap backfill, installation is convenient, fast and reliable; due to the fact that backfill construction is carried out in the gap between the concrete prefabricated beams through the micro-expansive cement mortar backfill body, the working procedure is simplified, the backfill construction quality of the micro-expansive mortar is ensured, the phenomenon that because water flow scours the gap, cavitation happens is avoided, it is ensured that the surface of the gap between the concrete prefabricated beams is flat, flow passage is smooth, and safe operation of a project is ensured.
Description
Technical field
The utility model relates to a kind of processing structure for concrete prefabricated beam gap, belongs to technical field of building construction.
Background technology
In current hydroelectric project, for accelerating across the interim hole construction speed of dam body, generally concrete prefabricated beam is erected on to interim hole top as concrete construction formwork.But owing to being subject to the impact of precast beam construction technology and prefab form error, the larger gap of general existence between concrete prefabricated beam, in hydroelectric project practice of construction process, as bridge in husky a small bay in a river, lattice etc. has all been ignored the backfill processing to gap.For the interim hole that had water requirement, in the time that flow rate of water flow is larger, the concrete prefabricated girder construction at position, gap is formed and washes away and produce cavitation erosion, bring great potential safety hazard to interim hole operation.Facts have proved, between concrete prefabricated beam, gap processing is an extremely important easy unheeded technical problem again, once process in gap between concrete prefabricated beam, will bring hidden danger to engineering safety operation.
Summary of the invention
The purpose of this utility model is to provide a kind of processing structure for concrete prefabricated beam gap, overcomes the deficiencies in the prior art, can avoid current scour gap to cause the generation of cavitation erosion, guarantees engineering safety operation.
The purpose of this utility model is achieved through the following technical solutions: a kind of processing structure for concrete prefabricated beam gap, it comprises and is arranged in the gap of concrete prefabricated beam, is detachably arranged on the counter of gap bottom and hangs template and be arranged in the micro-expansion cement mortar backfill body in gap.
The described anti-template of hanging is fixed on lock(ing) bolt, and lock(ing) bolt is arranged in gap.
The bottom of described concrete prefabricated beam is provided with water resistant stream erosional layer.
The beneficial effects of the utility model are: use the detachable anti-construction formwork of template as the gap backfill of concrete prefabricated beam that hang of installing, install convenient reliable, secondly, between concrete prefabricated beam, gap adopts micro-expansion cement mortar backfill body to carry out backfill construction, simplify operation, ensure the backfill construction quality of microdilatancy mortar, avoid current scour gap to cause the generation of cavitation erosion, also guaranteed that between concrete prefabricated beam, gap face is smooth, overcurrent is smooth-going, has ensured engineering safety operation
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, the anti-template of hanging of 1-, 2-lock(ing) bolt, the concrete prefabricated beam of 3-, 4-micro-expansion cement mortar backfill body, 5-gap, 6-water resistant stream erosional layer.
Detailed description of the invention
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As Fig. 1, a kind of processing structure for concrete prefabricated beam gap, it comprises the gap 5 that is arranged in concrete prefabricated beam 3, detachably being arranged on the counter of 5 bottoms, gap hangs template 1 and is arranged in the micro-expansion cement mortar backfill body 4 in gap 5, guarantee that 4 expansions of microdilatancy mortar fit tightly afterwards and between concrete prefabricated beam 3, micro-expansion cement mortar backfill body 4 not only possesses microdilatancy performance, gap between can intact fill concrete precast beam, and mortar possesses higher-strength, can resist high flow rate current scour, under the washing away of high-velocity flow, can not destroyed by rush of water or be produced and be come off, make the gap face in concrete prefabricated beam 3 smooth, overcurrent is smooth-going, the operation of guarantee engineering safety.
The described anti-template 1 of hanging is fixed on lock(ing) bolt 2, and lock(ing) bolt 2 is arranged in gap 5, spillage not when guaranteeing the gap 5 of concrete prefabricated beam 3 to carry out backfill.
The bottom of described concrete prefabricated beam 3 is provided with water resistant stream erosional layer 6, has met so the anti-current scour requirement of solidifying native precast beam 3.
Adopt micro-expansion cement mortar backfill body 4 to carry out backfill processing to the gap 5 of concrete prefabricated beam 3.When micro-expansion cement mortar backfill body 4 backfill constructions complete and reach after certain age strength, remove the anti-template 2 of hanging, install convenient, reliable.
Claims (3)
1. for the processing structure in concrete prefabricated beam gap, it is characterized in that: it comprises and is arranged in the gap (5) of concrete prefabricated beam (3), is detachably arranged on the counter of gap (5) bottom and hangs template (1) and be arranged in the micro-expansion cement mortar backfill body (4) in gap (5).
2. the processing structure for concrete prefabricated beam gap according to claim 1, is characterized in that: the described anti-template (1) of hanging is fixed on lock(ing) bolt (2) above, and lock(ing) bolt (2) is arranged in gap (5).
