[0002] The post-cast joint of the basement is a common construction technical measure in construction projects, mainly used in cast-in-place integral reinforced concrete structures. Due to the settlement of the basement outer wall, the post-cast joint cannot be closed for a long time, resulting in the inability to seal the basement outer wall waterproofing, affecting the subsequent backfilling of earth, so prefabricated walls are needed to seal the post-cast joint.

[0003] When using prefabricated walls to seal the post-cast strips, it is necessary to pour concrete between the prefabricated walls and the post-cast strips to connect the walls and the post-cast strips. During pouring, the cement on the post-cast strips and the prefabricated walls has dried and the surface is too flat, so the adhesion between them and the poured concrete is poor, and there is often a risk of falling off with long-term use. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a basement post-cast strip wall structure, aiming to improve the problem in the prior art that the prefabricated cement wall and the post-cast strip are already dry and have a relatively flat surface, and the adhesion between them and the poured concrete is poor, which often leads to the risk of falling off.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-4 The utility model provides an embodiment of a basement post-cast strip wall structure, comprising a wall 1, a mounting groove 3 is provided at the front end of the wall 1, a concrete precast panel 5 is placed inside the mounting groove 3, the concrete precast panel 5 is directly placed inside the mounting groove 3 of the wall 1, and there is no connection relationship between the concrete precast panel 5 and the mounting groove 3 at the front end of the wall 1. The concrete precast panel 5 and the wall 1 are usually connected and fixed by cement mortar sealing wall 11, so as to seal the post-cast strip. At the same time, a plurality of evenly distributed concave grooves 2 are provided on both sides of the concrete precast panel 5, and the concave grooves 2 can be used to increase the concave and convex degree of the side edge of the concrete precast panel 5, so as to enhance the bonding force between the cement mortar sealing wall 11 and the concrete precast panel 5, and a plurality of evenly distributed convex grooves 4 are fixedly connected on both sides of the inner side wall of the mounting groove 3, so as to increase the convexity of the side wall of the mounting groove 3, so as to enhance the bonding force between the cement mortar sealing wall 11 and the concrete precast panel 5, and the cement mortar sealing wall 11 is a mixture of cement mortar with a ratio of 1:25.

[0028] The convex blocks 9 are fixedly connected between the multiple grooves 2 on the concrete precast side edge, and the convex blocks 9 can be used to further increase the roughness of the side wall of the concrete precast panel 5.

[0029] A plurality of evenly distributed steel bars 10 are fixedly connected inside the precast concrete panel 5. Both ends of the plurality of steel bars 10 penetrate the side wall of the precast concrete panel 5 and are fixedly connected with auxiliary plates 8. The tops of the plurality of auxiliary plates 8 are provided with mounting grooves 3. The steel bars 10 can increase the load-bearing capacity of the precast concrete panel 5.

[0030] Both ends of the wall 1 are fixedly connected with steel bars 7, and the other ends of the multiple steel bars 7 pass through the inner wall of the installation groove 3 and are fixedly connected with auxiliary plates 6. The bottom end of the auxiliary plate 6 is provided with a groove similar to the auxiliary plate 8. When using steel wire to fix the steel bars 7 and the steel bars 10, the steel wire can be placed in the grooves on the auxiliary plates 6 and the auxiliary plates 8 to prevent the steel wire from shaking after tightening.

[0031] Auxiliary piece 1 6 and auxiliary piece 2 8 are both configured as an arc structure. When installing the precast concrete panel 5, steel bar 1 7 and steel bar 2 10 can be inserted into the slots inside the auxiliary piece 1 6 and the auxiliary piece 2 8. The auxiliary piece 1 6 and the auxiliary piece 2 8 are combined into a complete cylindrical structure, so that the water between the steel bar 1 7 and the steel bar 2 10 is limited in the horizontal direction, that is, the horizontal limitation of the precast concrete panel 5 is realized, that is, the limitation of the precast concrete panel 5 is realized in the direction away from one side of the installation groove 3, thereby improving the limiting effect of the precast concrete panel 5. When using a lifting machine to lift the precast concrete panel 5, first move the precast concrete panel 5 to the top of the installation groove 3, and slowly lower the precast concrete panel 5. When the steel bar 2 10 on the precast concrete panel 5 is misaligned with the steel bar 1 7 inside the groove, the staff can push the precast concrete panel 5 in the direction of the installation groove 3 to allow the precast concrete panel 5 to enter the groove, and then continue to lower the precast concrete panel 5 so that the auxiliary piece 1 6 contacts the bottom end of the steel bar 2 10, and the bottom end of the auxiliary piece 2 8 contacts the steel bar 1 7. At this time, the auxiliary piece 1 6 and the auxiliary piece 2 8 can respectively limit and fix the steel bar 2 10 and the steel bar 1 7, thereby performing preliminary limiting on the precast concrete panel 5 that has been lifted and installed, to prevent the precast concrete panel 5 from being horizontally displaced due to vibration.

[0032] Auxiliary piece 1 6 and auxiliary piece 2 8 are bound with steel wire. Compared with the existing method of directly using steel wire to connect steel bar 1 7 and steel bar 2 10, the steel wire can be wrapped around the groove on the outside of auxiliary piece 1 6 and auxiliary piece 2 8 and tightened during bundling, so as to limit the steel wire when the poured cement mortar sealing wall 11 is not completely dry, preventing the steel wire from shaking due to slight vibration, thereby affecting the binding effect between steel bar 1 7 and steel bar 2 10.

[0033] A waterproof membrane 12 is fixed on the outside of the wall 1, and the waterproof membrane 12 covers the precast concrete slab 5. The waterproof membrane 12 can increase the waterproof ability of the wall 1 and the precast concrete slab 5. After the waterproof membrane 12 is laid, the outside of the wall 1 and the precast concrete slab 5 can be backfilled with plain soil 13.

[0034] Working principle: When it is necessary to backfill the soil on the outer wall of the basement, the precast concrete panel 5 can be placed inside the installation groove 3 in front of the wall 1, and the steel bar 1 7 and the steel bar 2 10 can be connected, and the auxiliary piece can be overlapped to the bottom of the steel bar 2 10, and the auxiliary piece 2 8 can be overlapped to the top of the steel bar 1 7. At the same time, the iron wire used to fix the steel bar 1 7 and the steel bar 2 10 is placed inside the slot outside the auxiliary piece and the auxiliary piece 2 8, and the steel wire is tightened to connect the steel bar 1 7 and the steel bar 2 10. After that, cement mortar can be poured between the precast concrete panel 5 and the installation groove 3 to seal the wall 11 to fix the precast concrete panel 5. The precast plate 5 is connected and fixed to the installation groove 3. After the cement mortar sealing wall 11 is poured, the cement mortar sealing wall 11 will contact the inner wall of the installation groove 3 and the convex pattern 4 fixed on the inner wall of the installation groove 3, and at the same time, the other side will contact the concave pattern 2 on the side of the precast concrete plate 5, thereby increasing the adhesion between the cement mortar and the installation groove 3 and the precast concrete plate 5. Then, a waterproof membrane 12 can be laid on the outer side of the precast concrete plate 5 and the wall 1, thereby increasing the waterproof effect of the precast concrete plate 5 and the wall 1. After the waterproof membrane 12 is laid, the plain soil 13 can be backfilled on the outer side of the wall 1.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
