Description

Technical Field

[0001] The utility model belongs to the technical field of post-cast strips, and in particular relates to an advanced closed structure of a vertical post-cast strip of a basement. Background Art

[0002] In the field of building construction, the sealing process of the vertical post-cast strips in the basement has always been a critical and complex link. The traditional post-cast strip sealing process usually requires waiting for the structures on both sides of the post-cast strip to settle evenly before sealing, which not only leads to a significant extension of the construction period, but also because the basement retaining wall cannot be closed for a long time, the subsequent processes are forced to lag behind, which in turn causes a series of problems.

[0003] First, the long wait not only increases the time cost of the project, but may also have a serious impact on the overall progress of the project. Secondly, due to the long closure time of the post-casting strip, the subsequent construction was not carried out in time, and the foundation pit around the basement also faced safety risks, such as soil erosion, groundwater infiltration and other problems. Finally, from a cost-effectiveness perspective, the long suspension of work and delayed construction undoubtedly increased the overall cost of the project, which is not conducive to cost control and savings.

[0004] Therefore, it is very necessary to invent a kind of advanced closed structure of the vertical post-casting belt of the basement. Utility Model Content

[0008] Preferably, the precast concrete panel is in the form of a male and female tenon made of concrete, and the transverse steel bars and the longitudinal steel bars arranged inside the precast concrete panel together construct a single-layer bidirectional steel bar structure.

[0009] Preferably, the steel bar anchor ring is composed of two parts, an outer protrusion and an edge roll, both of which are "U"-shaped structures. The outer protrusion of the steel bar anchor ring is located on the outside of the concrete precast slab, while the edge roll is arranged inside the concrete precast slab, wherein the edge roll is wrapped around the outside of the longitudinal steel bars and is wrapped around at least two of the longitudinal steel bars.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The key to the structure of this utility model is that it can close the post-casting strip in advance, saving construction time and ensuring the safety of the foundation pit edge at the construction site. The raw materials of the precast concrete panels come from the residual materials of the structural concrete, eliminating the waste of materials; the precast concrete panels are made into male and female tenons for easy installation by workers and leakage prevention of the post-casting strip. This design has significantly improved the project quality and construction efficiency with its excellent construction convenience, structural stability, versatility of the anchor ring design, enhanced protection of the anchor ring from pulling out, excellent performance in waterproofing and connectivity, and wide applicability.

[0012] First, the single-layer bidirectional steel bar design inside the precast panel effectively enhances its ability to resist the external soil pressure and ensures the stability of the structure. In addition, the embedded anchor ring is not only used for fixing during installation and transportation, but also serves as a fixing connector for the inner formwork screw when pouring the post-casting zone concrete, realizing the multifunctional application of the anchor ring. To ensure that the anchor ring will not be pulled out when subjected to force, two additional anchor steel bars are added to each anchor ring, which significantly enhances the overall safety of the structure.

[0019] As attached Figure 1 To Attachment Figure 2 As shown:

[0020] The utility model provides a pre-closed structure of a vertical post-cast strip in a basement, comprising a basement waterproof layer 1, pre-cast concrete 2, concrete steel bars 3, a steel plate waterstop 4, a post-cast strip area 5, a concrete precast slab 6, transverse steel bars 7, longitudinal steel bars 8 and a steel bar anchor ring 9, wherein the pre-cast concrete 2 is arranged on the basement waterproof layer 1, the pre-cast concrete 2 is provided with concrete steel bars 3 and a steel plate waterstop 4, and the steel plate waterstop 4 is located in the post-cast strip area 5 formed by the pre-cast concrete 2; the concrete precast slab 6 is arranged below the post-cast strip area 5, and the transverse steel bars 7, longitudinal steel bars 8 and a steel bar anchor ring 9 are arranged inside the concrete precast slab 6.

[0021] Embodiment 1:

[0022] Specifically, the basement waterproof layer 1 is composed of a base layer, an additional waterproof layer, a waterproof protective layer and a water pressure resistant cushion layer from bottom to top, wherein the water pressure resistant cushion layer is provided with a steel bar layer. It not only has excellent waterproof performance, but also has a stable structure, can effectively resist groundwater pressure, and protect the dryness and safety of the basement interior.

[0023] Specifically, the edge of the first poured concrete 2 is roughened mechanically or manually to form an irregular concave-convex surface, thereby increasing the bonding force between the post-poured concrete and the first poured concrete, so that the two can be more closely combined to avoid cracks or leakage. The two ends of the steel plate waterstop 4 are bent, and during construction, a part of the steel plate waterstop 4 is embedded in the interior of the first poured concrete 2. In this way, when the post-poured concrete is poured, the steel plate waterstop can be in close contact with the concrete on both sides to form a complete waterproof barrier. At the same time, the other part of the steel plate waterstop 4 is located on both sides of the middle area of ​​the post-poured belt area 5. Such a layout ensures that the steel plate waterstop can effectively cover the entire post-poured belt area to prevent groundwater from penetrating into the interior of the building from any direction.

[0024] Specifically, the concrete prefabricated panel 6 is made of concrete and is specially designed in the form of male and female tenons. This design makes the installation process between the prefabricated panels simpler and faster, greatly improving the construction efficiency. The transverse steel bars 7 and the longitudinal steel bars 8 arranged inside the concrete prefabricated panel 6 are two sets of steel bars that cross each other and jointly construct a single-layer bidirectional steel bar structure. This steel bar structure design not only enhances the overall strength of the prefabricated panel, but also improves its ability to resist external pressure and deformation.

[0025] Specifically, the steel bar anchor ring 9 is composed of two parts, an outer protrusion and an edge roll, both of which are "U"-shaped structures, ensuring its strength and stability. The outer protrusion is located on the outside of the concrete precast panel 6, which plays a role in enhancing the overall strength of the anchor ring, and is also conducive to connection with external structures or equipment, while the edge roll is arranged inside the concrete precast panel 6, wherein the edge roll is wound around the outside of the longitudinal steel bar 8, and at least two of the longitudinal steel bars 8 are wound around, which not only enhances the connection strength between the anchor ring and the steel bar, but also effectively prevents the anchor ring from sliding or shifting when subjected to force. Usually, the edge roll is wound around at least two longitudinal steel bars 8 to ensure a firm connection with multiple steel bars, thereby improving the stability and safety of the entire structure.

[0026] Embodiment 2:

[0027] The pre-enclosed structure of the vertical post-casting strip in the basement adopts a specially designed concrete precast slab 6, whose dimensions are: length = post-casting strip width + 200mm, width 600mm, thickness 100mm, and the concrete strength reaches C30 or above to ensure the stability of the structure. The precast slab is carefully arranged with a single layer of bidirectional steel bars, of which the inner steel bars are φ12@200 and the retaining side is φ10@300, to strengthen the structure and enhance the ability to resist the outer soil pressure.

[0028] In order to facilitate installation and improve construction efficiency, the concrete precast panel 6 is made into a male and female tenon form. 2φ10 and 4φ12 anchor rings with a length of 300mm and single-layer bidirectional steel bars are also embedded in the panel. These anchor rings are not only used for fixing during installation and transportation, but also serve as fixed connectors for the inner formwork screws when pouring concrete in the post-casting zone, realizing multifunctional applications.

[0029] In order to further enhance the stability of the structure, each pre-buried steel bar anchor ring 9 is wrapped around two φ12 300mm long additional anchoring steel bars of the single-layer bidirectional steel bars, which effectively prevents the anchor ring from being pulled out when subjected to force. At the same time, the wall body tongue and groove are reserved for the structure on both sides of the post-cast strip during construction, which not only facilitates the installation and fixation of the prefabricated panels, but also ensures the integrity of the structure.

[0030] Cement mortar R feet are specially designed at the junction of the concrete precast slab 6 and the walls on both sides of the post-cast strip. This design is not only conducive to ensuring the quality of subsequent waterproofing construction, but also ensures a tight connection between the precast slab and the post-cast strip wall, thereby effectively preventing problems such as water seepage. Through this comprehensive design and meticulous construction, the advanced closed structure of the vertical post-cast strip in the basement has achieved a comprehensive improvement in structural stability, construction convenience and waterproof performance.

[0031] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
