The utility model discloses a quick closing means of basement post-cast strip adopts prefabricated modular standard board, easy operation, construction convenience, and the operation space demand is little, and construction speed is fast, can seal immediately after the outer wall form removal, and reducible post-cast strip pollutes, effectively promotes post-cast strip quality promotion, promotes the fertile groove of foundation ditch and backfills fast.
Description
Technical Field
The utility model belongs to the technical field of the construction, in particular to quick closing means of basement post-cast strip.
Background
The pollution, the cleaning and the construction quality of the post-cast strip are always the main points of construction quality control of building engineering, the backfilling of the fertilizer groove of the foundation pit is used as a key point and an important assessment index of progress control, the quick backfilling of the fertilizer groove is beneficial to field-level conversion and field safety civilized construction management, the space requirement of a construction working surface of a traditional post-cast strip masonry rotating tire membrane protection method is large, the construction speed is low, the efficiency is low, the backfilling of the fertilizer groove of the foundation pit can be carried out only after cement mortar reaches certain strength by a brick tire membrane protection method, the process pause time is long, the backfilling is influenced by a basement floor frame, the working space is narrow, and the operation of workers is difficult.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems in the prior art and provide a rapid sealing device for a basement post-cast strip,
the technical scheme of the utility model as follows:
the utility model provides a quick closing means of basement post-cast strip, comprises a plurality of prefabricated modularization standard slabs, and this prefabricated modularization standard slab sets up the pre-buried pendant of being connected with the post-cast strip reinforcing bar, and pre-buried pendant and the longitudinal reinforcement welding of post-cast strip.
The prefabricated modular standard plate is a reinforced concrete plate, the standard size is 800 multiplied by 1600mm, the thickness of the prefabricated modular standard plate is not less than 60mm, and the edge of the post-cast strip extending out of each edge of the prefabricated modular standard plate is not less than 250 mm.
Furthermore, the pre-buried pendant adopts 8mm diameter round steel preparation.
Furthermore, a lining structure adopting 1:2 waterproof mortar is arranged between the prefabricated modular standard plates, and a plastering mortar layer is formed on the outer side by adopting 1:2 cement mortar for plastering and calendaring.
Compared with the prior art, the utility model discloses a quick closing means of basement post-cast strip adopts prefabricated modular standard board, easy operation, and construction convenience, operation space demand is little, and construction speed is fast, can seal immediately after the outer wall form removal, and reducible post-cast strip pollutes, effectively promotes post-cast strip quality and promotes, promotes the fertile groove of foundation ditch and backfills fast.

Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1-3: it includes prefabricated modularization standard plate 1, with the pre-buried pendant 2 of the bar connection of post-cast strip 7. Wherein, the prefabricated modular standard plate 1 has strong concreteDegree class C30, internal configuration
The setting time of the bidirectional steel bar is not less than 28 days, and 4 prefabricated modular standard plates 1 are arranged
The end parts of the embedded hanging pieces 2 are provided with 90-degree hooks, and the fine adjustment and the post-cast strip longitudinal steel bars 3 are hung and connected and fixed in a spot welding mode during use.
The prefabricated modular standard plate 1 extends towards the two sides of the post-cast strip by not less than 250mm, waterproof coiled materials on the two outer sides of the post-cast strip 7 are pressed, four embedded hanging pieces 2 are respectively arranged on each prefabricated modular standard plate 1 in the longitudinal direction and the transverse direction, and the prefabricated modular standard plate is fixed by spot welding from the inner side of the post-cast strip 7.
The prefabricated modular standard plates 1 are lined with 1:2 waterproof mortar, and post-cast pre-buried water stops 6 are arranged; the prefabricated modular standard board 1 and the shear wall 5 of the basement are staggered to form obtuse angles by adopting 1:2 waterproof mortar, and the plastering mortar layer 4 on the outer side of the prefabricated modular standard board 1 is 15mm thick by adopting a 1:2 waterproof mortar plastering cover surface, so that the construction of waterproof coiled materials is facilitated.
The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
