Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of basement exterior wall post-casting strip construction, in particular to a ribbed folding line plate and a basement exterior wall post-casting strip closed structure. Background Art
[0002] In the process of high-rise building construction, the retention of post-cast joints is to prevent harmful cracks caused by uneven shrinkage or settlement of cast-in-place reinforced concrete structures during construction. Temporary construction joints are left in corresponding positions according to design or construction specifications. The settlement post-cast joints set at the connection between the basement and the main building according to the design requirements can only be poured more than 60 days after the main building structure is capped or longer according to the design requirements. In this case, the backfill work of the waterproof layer and outdoor earthwork at the location of the post-cast joint of the basement exterior wall cannot be carried out smoothly. In case of rain and snow, and rainwater enters the basement, it is necessary to spend manpower and material resources for drainage, and protective measures must be taken. For construction sites with narrow sites or projects that require precipitation, if the subsequent waterproof layer, backfill soil, hardened site and other construction cannot be carried out in time, it will also affect the on-site construction plane layout, which will affect the subsequent construction, resulting in difficulties in the layout of the construction site, increased on-site costs and delays in the construction period. Therefore, it is necessary to improve and perfect it. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a ribbed folding plate and a basement outer wall post-cast strip closed structure to solve the problems of complex masonry construction procedures at the basement outer wall post-cast strip in the prior art, easy cracking and leakage, long construction period and high cost.
[0004] The utility model solves the above-mentioned technical problems with a technical solution as follows: a ribbed fold line plate, comprising: a reinforced concrete body and a plurality of waterstop screws, one end of each waterstop screw being fixed in the reinforced concrete body, the other end of each waterstop screw being outside the reinforced concrete body and fixing the waterstop steel plate, the upper and lower ends of the reinforced concrete body respectively having a tenon and a mortise.
[0005] The beneficial effects of the utility model are as follows: the ribbed broken line plate components are easy to manufacture on site, are relatively light, and have simple construction operations. They can solve the interference caused by the unsealed parts of the post-cast strips on the basement exterior walls to the construction. They have a firm structure, are easy to install, have strong durability, and are easy to replace. They can reduce construction costs, greatly shorten the construction period, and create conditions for cross-operation and flow construction, thereby speeding up the construction progress.
[0006] On the basis of the above technical solution, the present invention can also be improved as follows.
[0007] Furthermore, a single-layer bidirectional steel mesh is cast inside the reinforced concrete body.
[0008] Furthermore, the single-layer bidirectional steel mesh is made of HRB400Ф12mm threaded steel bars welded at a spacing of 150mm.
[0009] Furthermore, the reinforced concrete body has a plurality of cavities with dimensions of 100 cm×50 cm×10 cm, a middle rib height of 10 cm, and a side rib height of 5 cm.
[0010] Furthermore, the number of the water-stopping screws is at least two, and the water-stopping screws are located at the middle rib of the reinforced concrete body.
[0011] Furthermore, the diameter of the water-stop screw is 12 mm.
[0012] Based on the above technical scheme, the utility model also provides a closed structure for the post-cast strip of the basement exterior wall, including: a plurality of ribbed folded line plates 1 are arranged along the height direction on the outside of the post-cast strip of the basement exterior wall, two adjacent ribbed folded line plates are connected by mortise and tenon joints, a formwork is arranged on the inside of the post-cast strip of the basement exterior wall, and the water-stop screws on the ribbed folded line plates are fixed to the formwork.
[0013] The above further beneficial effects are: using the ribbed folded plate as the outer fetal membrane of the post-cast strip of the basement outer wall, after the ribbed folded plate is fixed, the insulation layer, waterproof layer and protective layer can be constructed directly along the outer wall, that is, the waterproof construction can be carried out simultaneously with the other positions, eliminating the joints of the waterproof layer in this position, and not being disturbed by the current state of the post-cast strip. Compared with the traditional construction method, the basement outer wall waterproofing construction and earth backfilling work can be carried out in advance, which greatly improves the waterproof quality of the post-cast strip. After the post-cast strip is poured, the ribbed folded plate becomes a part of the outer wall. The ribbed folded plate not only serves as a protective wall at the post-cast strip position, but also will not be disturbed by the settlement of the post-cast strip, which greatly reduces the total construction period, saves the total construction period, saves construction costs, significantly improves the economic benefits of the project, and improves energy conservation and environmental protection. Through the mortise and tenon connection between the ribbed folded plates and the buried water-stop screws fixed to the reinforced concrete body, the protective wall assembled by the ribbed folded plates is effectively firmly connected to the shear wall, avoiding quality problems such as cracking of the protective wall and waterproof cracking.
[0014] Furthermore, the transverse length of the ribbed fold line plate is 50 cm greater than the transverse width of the post-cast strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The number of the waterstop screws 120 is at least two, and the waterstop screws 120 are located at the middle rib of the reinforced concrete body 110. The given drawings only show that there are two waterstop screws 120 on the middle rib of the reinforced concrete body 110. The diameter of the waterstop screws 120 used is preferably 12 mm. Of course, in actual application, the use of waterstop screws 120 of other sizes is not excluded.
[0031] Example 4
