Abstract
The utility model discloses a waterproof expansion seam structure for new and old concrete building joints, which comprises a water stop tie, expansion strips, seam inlay materials and seam filling materials, wherein one end of the water stop tie is pasted on an old concrete structure, the other end of the water stop tie extends into a new building structure, the seam filling materials on which the expansion strips are laid on the top and the bottom of the water stop tie, and the seam inlay materials are laid on the expansion strips. The utility model overcomes the disadvantages of inaccurate embedded positions, hard fixation and water stop function affection of the former intermediate embedded water stop tie, has the advantages of favorable waterproof effect, can enhance the quality of building engineering, and enables the building engineering to be safe and beautiful. The utility model not only can be applied to underground building engineering but also can be applied to ground building engineering under the waterproof requirement.
Description
Technical field:
The utility model relates to the waterproof expanded joint structure at a kind of new-old concrete building joints place.
Background technology:
In the transformation and enlarging of concrete construction engineering, often run into and building the new concrete construction of concrete work next door construction, comprise the situations such as prolongation of buildings such as hole wall, vestibule and terrace.Be used for the waterproof expanded joint structure of new and old building junction, requirement should be satisfied flexible needs, satisfies the needs of waterproof again.Because the shrinkage joint of adopting when new construction is the pre-buried structure of middle buried water stop in the past, can't stretch in the structure of old building, can not form effective water proof structure node, its result often influences the quality of building, and stay unsafe hidden danger, even cause unnecessary loss.
Summary of the invention:
The purpose of this utility model is: provide that a kind of stagnant water effect is good, the waterproof expanded joint structure at the new-old concrete building joints place of the quality that can improve construction work, to overcome the problems referred to above.
The utility model is to constitute like this: it comprises waterstop (1), expansion bar (2), caulking material (3) and pointing (4), one end of waterstop (1) is secured on the old concrete structure, the other end stretches in the new building structure, lay pointing (4) thereon, down, go up at pointing (4) and lay expansion bar (2), go up at expansion bar (2) and lay caulking material (3).
One end of waterstop (1) is made straight flange, and the other end is made 135 ° flanging, and the centre connects with circular arc.
Common inaccurate, the difficult disadvantage of fixing, influencing the sealing effect of burial place of buried water stop during the utility model has overcome in the past, good water-proof effect can improve the quality of construction work, makes construction work safety and attractive in appearance more.The utility model both can be used for underground structrue engineering, also can be used for having the surface structures engineering of waterproof requirement.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model, and the left side is a new construction, and the right is an old structure;
Accompanying drawing 2 is a waterstop full-page proof schematic diagram of the present utility model.
The specific embodiment:
Embodiment of the present utility model: the old concrete structural plane is cleaned up, and cutter hair a little, with the water proof type structure glue one end of steel plate water-stopping band (1) is pasted firmly, upper and lower laying pointing (4) at waterstop (1), use formwork to put positive ， Jiao Pound new construction with the other end of waterstop (1) is in place.After treating the shrinkage joint form removal, put into expansion bar (2), insert caulking material (3) at last, form complete flexible water proof structure at upstream face.Waterstop (1) is made of the 3mm corrosion resistant plate, and expansion bar (2) is made of rubber, and this rubber has the performance of water-swellable.
As special case of the present utility model, when the waterproof construction calling hierarchy is not high, can only use waterstop, need not expand bar and caulking material only get final product at the upper and lower pointing of filling in of waterstop.
Claims (2)
1. new-old concrete building joints waterproof expanded joint structure, it comprises waterstop (1), expansion bar (2), caulking material (3) and pointing (4), it is characterized in that: an end of waterstop (1) is secured on the old concrete structure, and the other end stretches in the new building structure, lays pointing (4) thereon, down, go up laying expansion bar (2) at pointing (4), go up at expansion bar (2) and lay caulking material (3).
2. new-old concrete building joints waterproof expanded joint structure as claimed in claim 1, it is characterized in that: an end of waterstop (1) is made straight flange, and the other end is made 135 ° flanging, and the centre connects with circular arc.
