Abstract
The utility model discloses a plugging structure for a post-cast strip of an underground building and aims to provide the plugging structure which is simple in structure, wide in range of application, convenient to construct, less in potential safety hazard and less in later period cost for the post-cast strip of the underground building. The plugging structure comprises a concrete external wall (1), the post-cast strip (2), a precast slab (3), connecting members (5), post-cast strip reserved steel bars (6) and a leveling layer (7). The precast slab (3) is arranged on the outside of the post-case strip (2); the connecting members (5) are connected with the precast slab (3) and the post-cast strip reserved steel bars (6); after the precast slab (3) is mounted, the leveling layer (7) is plastered on the outside of the precast slab (3). The plugging structure which is simple in structure is mainly composed of the external wall, the post-cast strip, the precast slab and the leveling layer. The precast slab is connected with the post-cast strip reserved steel bars through the connecting members, so that construction is facilitated; the precast slab and the leveling layer are arranged on the outside of the plugging structure, so that cost on border protection can be reduced after backfill of foundation pits.
Description
Technical field
The utility model relates to a kind of plugging structure of post-cast strip for underground building, belongs to building ater-casting manufacture technology field.
Background technology
In highrise building, due to the needs of function and moulding, often high-rise main building and garage are connected together, garage has surrounded the major part of main building.From traditional structure viewpoint, to wish high level and garage to throw off, this just need to establish deformation joint; But see and do not wish to establish seam from building requirements.Because establish seam, there will be twin beams, twin columns, Shuan Qiang, make plane figure restricted, so just arise at the historic moment in ater-casting.If but according to conventional method construction, after agent structure Equalsettlement, carry out again ater-casting construction, can have a strong impact on integral construction progress.So, after Underground Construction, in order to ensure carrying out smoothly of underground outdoor water-proof and backfill engineering, must to the post-pouring belt of outer wall of basement, carry out block in advance, form a whole late poured band structure.
Application number is the structure that 201020583478.9 utility model patent file discloses a kind of post-cast strip for underground building, comprises melt pit bottom cushion, agent structure and ater-casting, also has waterproof roll and external labeling type waterstop.Use due to waterproofing materials, make this utility model there is good waterproof, seepage control effect, and the feature due to this structure, make this kind of structure mainly be applicable to ground geological conditions better, on semi-underground power transformation rectification chamber base plate in cell room when groundwater table is higher and sidewall, use, so this structure is used does not have generality, limitation is larger.
Utility model content
In order to overcome above-mentioned defect, the technical problems to be solved in the utility model is: provide a kind of simple in structure, scope of application extensively, easy construction, minimizing potential safety hazard, reduce the plugging structure of the post-cast strip for underground building of later stage expense.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of plugging structure of post-cast strip for underground building, comprise concrete exterior wall and ater-casting, and also comprise precast plate, connector, ater-casting reserved steel bar and leveling layer.Described precast plate is thrown into the outside of ater-casting, and connector connects precast plate and ater-casting reserved steel bar.After precast plate is installed, leveling layer is put on precast plate outside.
Described precast plate is provided with precast plate groove, and connector passes thus.
Described connector is T-shaped.
When described ater-casting reserved steel bar is positioned at the position that can not be connected with connector, in concrete exterior wall inner side, be welded with reinforcing bar, be connected with connector.
Described leveling layer is cement mortar screeding layer.
The beneficial effects of the utility model are: 1, primary structure of the present utility model is exactly exterior wall, ater-casting, precast plate and leveling layer, so simple in structure.2, precast plate is connected with ater-casting reserved steel bar by connector, easy construction.3, there are precast plate and leveling layer in the outside of this structure, can reduce and face the expense that frontier defense is protected after pit backfill.4, avoid foundation ditch long term exposure, reduce the potential safety hazard in engineering.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, illustrate the plugging structure of post-cast strip for underground building described in the utility model.
Fig. 1 is precast plate plan view;
Fig. 2 is precast plate lateral view;
Fig. 3 is connecting-piece structure schematic diagram;
Fig. 4 is the plugging structure schematic diagram of post-cast strip for underground building.
In figure: 1, concrete exterior wall, 2, ater-casting, 3, precast plate, 4, precast plate groove, 5, connector, 6, ater-casting reserved steel bar, 7, leveling layer.
The specific embodiment
As Figure 1-4, a kind of plugging structure of post-cast strip for underground building, comprises concrete exterior wall 1 and ater-casting 2, also comprises precast plate 3, connector 5, ater-casting reserved steel bar 6 and leveling layer 7.Described precast plate 3 is thrown into the outside of ater-casting 2, and connector 5 connects precast plate 3 and ater-casting reserved steel bar 6.After precast plate 3 is installed, leveling layer 7 is put on precast plate 3 outsides.
Described precast plate 1 is provided with precast plate groove 4, and connector 5 passes thus.
Described connector 5 is T-shaped, is welded, and does antirust processing with reinforcing bar, and length must not surpass concrete exterior wall 1.
When described ater-casting reserved steel bar 6 is positioned at the position that can not be connected with connector 5, in concrete exterior wall inner side, be welded with reinforcing bar, be connected with connector 5.
Described leveling layer 7 is cement mortar screeding layer.
The precast plate 3 that reaches intensity is transported to behind scene, installs.Install after a precast plate, installation connecting element 5 immediately, and connector 5 two ends are stuck in precast plate groove 4 both sides, and go deep into ater-casting 2 by precast plate groove 4, with ater-casting reserved steel bar 6 firm welding.When reserved steel bar 6 positions in ater-casting can not be connected with connector 5, in body of wall inner side, be welded with reinforcing bar.Precast plate side weld must limit during installation be installed and connects, and reinforce firmly, welding together after several precast plates must not be installed, prevent the landing of precast plate unstability.
After precast plate 3 is installed, leveling layer 7 is smeared in outside, and makes 45 degree oblique angles at precast plate and concrete exterior wall seam crossing, for waterproof construction is prepared.
