This basement post-cast strip can avoid the problem of unstable post-cast strip construction and installation, and effectively improves the waterproofing effect.

[0004] Before pouring, the post-cast concrete strip needs to be connected with the steel bars of the first-cast concrete, and then the pouring operation of the post-cast concrete strip can be carried out. On the one hand, there is a problem of long construction time. On the other hand, the steel bars of the first-cast concrete need to be exposed to the outside for a long time and are prone to rust. In order to solve the above problems, a construction structure of the post-cast concrete strip of the basement concrete component is proposed. Utility Model Content

At this time, one end of the threaded steel bar is connected to the first concrete, and the other end is located inside the second concrete, thereby connecting the first concrete and the second concrete, improving the strength between the two. On the other hand, there is no need to carry out tedious steel bar connection procedures, which greatly improves the pouring efficiency of the second concrete strip.

[0008] In a preferred embodiment, a waterproof layer and a reinforced waterproof layer are laid in sequence from bottom to top inside the concrete cushion layer.

[0009] Through the above technical solution, the waterproof effect of the concrete cushion layer is improved by setting up a waterproof layer and strengthening the waterproof layer, thereby preventing groundwater from overflowing.

[0010] In a preferred embodiment, a steel mesh partition is provided at the connection between the first-cast concrete and the second-cast concrete.

[0011] Through the above technical solution, by setting up steel mesh partitions, it not only helps to improve the overall stability and durability of the structure, but also effectively controls the formation of cracks.

[0012] In a preferred embodiment, a water retaining steel plate is fixedly installed between the first poured concrete and the second poured concrete.

[0013] Through the above technical solution, the installation of water-retaining steel plates can effectively prevent ground water from penetrating, thereby ensuring the waterproof performance of the building structure.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] The following will be combined Figure 1-3 A construction structure of a post-cast strip of a basement concrete component in an embodiment of the utility model is described in detail.

[0024] Example:

[0025] A basement concrete component post-cast strip construction structure, comprising:

[0026] Concrete cushion layer 1, on the upper surface of which is poured pre-cast concrete 2, and inside the concrete cushion layer 1 are laid out a waterproof layer 8 and a reinforced waterproof layer 9 from bottom to top. The provision of the waterproof layer 8 and the reinforced waterproof layer 9 improves the waterproof effect of the concrete cushion layer 1 and prevents groundwater from overflowing;

[0027] A plurality of connection seats 4 are pre-buried on both sides of the middle of the first poured concrete 2, and a threaded steel bar 5 is threadedly connected to one side of the connection seat 4. The middle of the first poured concrete 2 is poured with post-poured concrete 3, and the post-poured concrete 3 is a micro-expansion concrete with an expansion rate of 0.04%. A steel plate mesh partition 6 is provided at the connection between the first poured concrete 2 and the post-poured concrete 3. The provision of the steel plate mesh partition 6 not only helps to improve the overall stability and durability of the structure, but also effectively controls the formation of cracks. A water retaining steel plate 7 is fixedly installed between the first poured concrete 2 and the post-poured concrete 3. The provision of the water retaining steel plate 7 can effectively prevent ground water from penetrating. To ensure the waterproof performance of the building structure, the threaded steel bar 5 is located inside the post-cast concrete 3. When pouring the first-cast concrete 2, the connecting seat 4 is first embedded in the first-cast concrete 2. When pouring the post-cast concrete 3, it is only necessary to thread the threaded steel bar 5 to one side of the connecting seat 4, and then pour the post-cast concrete 3. At this time, one end of the threaded steel bar 5 is connected to the first-cast concrete 2, and the other end is located inside the post-cast concrete 3, thereby connecting the first-cast concrete 2 and the post-cast concrete 3, thereby improving the strength between the two. On the other hand, there is no need to carry out cumbersome steel bar connection procedures, which greatly improves the pouring efficiency of the post-cast strip.

[0028] An external waterstop 10 is fixedly installed at the center of the upper surface of the reinforced waterproof layer 9, and a waterproof embedding material 11 is fixedly installed at the center of the upper surface of the external waterstop 10. At the junction of the upper surface of the waterproof embedding material 11 and the lower surface of the post-cast concrete 3, the external waterstop 10 can effectively prevent moisture from penetrating into the interior of the building through joints or cracks. This waterstop is usually installed on the outside of the concrete structure, and through its good elasticity and sealing properties, it forms a solid line of defense to block the intrusion of moisture. Secondly, the external waterstop 10 also has the ability to adapt to structural deformation. When a building is affected by factors such as temperature changes or foundation settlement, the structure will deform to a certain extent. The external waterstop can expand and contract as the structure deforms, maintaining its sealing effect, thereby avoiding water leakage problems caused by structural deformation.

[0029] Working principle:

[0030] When pouring the first concrete 2, the connecting seat 4 is first embedded in the first concrete 2. When pouring the second concrete 3, it is only necessary to thread the threaded steel bar 5 to one side of the connecting seat 4, and then pour the second concrete 3. At this time, one end of the threaded steel bar 5 is connected to the first concrete 2, and the other end is located inside the second concrete 3, thereby connecting the first concrete 2 and the second concrete 3, improving the strength between the two. On the other hand, there is no need to carry out cumbersome steel bar connection procedures, which greatly improves the pouring efficiency of the second concrete strip.
