Description
Technical Field
[0001] The utility model relates to the technical field of same-floor drainage of toilets, in particular to a prefabricated external wall node structure at the same-floor drainage of toilets. Background Art
[0002] Considering the usage requirements of residents, existing residential buildings have the same-floor drainage drop requirements for bathrooms. The conventional caisson drop size is 300-350mm high, plus the bathroom slab thickness of 120mm. Considering lighting, conventional buildings generally control the window top size to about 500mm. Due to the same-floor drainage bathroom floor drop, there is less than 100mm left at the bathroom window top, resulting in the size from the window top to the slab bottom cannot meet the requirements of prefabricated reserved window frames. The commonly used solution is to reduce the bathroom window height, increase the window top size, meet the prefabricated size from the window top to the caisson slab bottom, and prefabricate the exterior wall to the same-floor drainage slab bottom, but this solution has the following problems:
[0003] (1) This method is suitable for the situation where the toilet is relatively independent or hidden. If it is located on the main facade of the building, there will be inconsistency between the top of the window of the building facade, which will affect the effect of the building facade.
[0004] (2) When the bathroom on the north side has a smaller span and is adjacent to a kitchen with the same smaller span, the structural layout often needs to combine the two functional areas into a beam component. For the prefabricated exterior walls of prefabricated houses, the two functional walls are usually prefabricated as a whole. Using the above method, there will be problems such as the height of the kitchen window and the height of the bathroom window being inconsistent, and the steel bars at the bottom of the structural beam cannot be pulled through and need to be interrupted.
[0005] In view of this, there is an urgent need to develop a prefabricated exterior wall structure for the same-floor drainage bathroom to solve the problems in the prior art such as inconsistent bathroom window heights and the inability to pull through the steel bars at the bottom of the structural beam and the need to break them.

[0027] according to Figure 1 and Figure 2 The utility model shows a prefabricated exterior wall node structure at the same-floor drainage of a bathroom, including a prefabricated exterior wall 10 for a window sill, a bathroom floor 20, a prefabricated composite beam 30 at the window top, and a vertical folded plate 21 in the bathroom floor 20. Compared with the prior art, the present application can achieve the same prefabricated exterior wall at the same-floor drainage bathroom as the conventional exterior wall, with a uniform window top height, a pull-through setting of the beam bottom reinforcement, and only a simple folded plate node of the same-floor drainage bathroom caisson structural plate is added to the inner side of the prefabricated exterior wall. The above effect can be achieved by combining the composite layer reinforcement setting of the prefabricated wall top beam. The method is simple and effective. At the same time, the surrounding structural beams of the bathroom do not need to be changed, and the load-bearing bottom reinforcement does not need to be interrupted, thereby ensuring the load-bearing performance of the structure.
[0028] In this embodiment, the end of the window sill prefabricated exterior wall 10 is connected to the reserved hole of the exterior wall of the main structure by vertical positioning grouting through the reserved steel bars. The prefabricated window sill exterior wall 10 only needs to be prefabricated according to conventional exterior walls during prefabrication, without considering the disconnection of the beam force steel bars and the treatment of steel bar joints.
[0029] Specifically, a lower window sill plate is cast on the outer side of the prefabricated window sill exterior wall 10 .
[0030] In this embodiment, the window top prefabricated composite beam 30 is cast as a whole with the window sill prefabricated outer wall 10 through the cast-in-place composite layer 40 on the top, and composite beam reinforcement is provided inside the window top prefabricated composite beam 30 .
[0031] In this embodiment, the bathroom floor 20 is a caisson structure, and a vertical folded plate 21 intersecting vertically and horizontally is provided on the inner side of the caisson structure. A double-layer bidirectionally arranged floor steel bar is provided on the vertical folded plate 21, and the reinforcing steel bar is hooked with the composite beam steel bar; wherein the vertical folded plate 21 and the prefabricated composite beam 30 at the top of the window are cast as a whole.
[0032] Specifically, the reinforcing steel bars include a first floor slab steel bar 22 and a second floor slab steel bar 23. The first floor slab steel bar 22 includes two steel bars arranged in parallel along the transverse plate 211 of the vertical folded plate 21. The two steel bars are bent at right angles and anchored into the longitudinal plate 212 of the vertical folded plate 21 and overlapped. The second floor slab steel bar 23 includes a steel bar arranged along the longitudinal plate 212 of the vertical folded plate 21. One end of the steel bar is bent toward the upper side of the prefabricated composite beam 30 at the top of the window to form an annular hoop reinforcement, and the other end is anchored in the transverse plate 211 of the vertical folded plate 21.
[0033] Specifically, Figure 1 , Figure 2 As shown, the first floor steel bar 22 and the second floor steel bar 23 are independent single-layer steel bars, forming a double-layer bidirectionally arranged floor steel bar. The annular hoop of the second floor steel bar 23 hooks the upper steel bar 31 of the composite beam on the upper side of the prefabricated composite beam 30 at the top of the window and the additional steel bar 32 on the lower side, so as to realize the connection between the cast-in-place composite layer 40 of the window and the vertical folded plate 21 of the bathroom, and solve the problem of insufficient size of the prefabricated wall window top at the same-level drainage bathroom when the prefabricated exterior wall encounters. At the same time, the first floor steel bar and the second floor steel bar 23 are both provided with reinforcing ribs, which are perpendicular to the plane where the first floor steel bar 22 and the second floor steel bar 23 are located, so as to improve the integrity and force-bearing performance of the vertical folded plate 21 and the post-cast cast-in-place composite layer 40.
[0034] Specifically, the composite beam reinforcement includes composite beam upper reinforcement 31 on the upper side of the window top prefabricated composite beam 30 and additional reinforcement 32 on the lower side. The composite beam upper reinforcement 31 on the upper side of the window top prefabricated composite beam 30 and the additional reinforcement 32 on the lower side are connected end to end to form a rectangular stirrup, the upper side of the rectangular stirrup is anchored in the cast-in-place composite layer 40, and the lower side of the rectangular stirrup is anchored in the window top prefabricated composite beam 30.
[0035] Specifically, the width of the vertical folded plate 21 is consistent with the thickness of the bathroom floor 20 .
[0036] Specifically, a waterproof sealing layer is provided on the connection surface between the window sill prefabricated exterior wall 10 and the cast-in-place superimposed layer 40, and the connection surface is set to a rough surface. The connection surface of the window sill prefabricated exterior wall 10 is set to a rough surface, which can enhance the connection with the post-cast concrete, and the waterproof sealing layer can ensure the waterproof effect of the joint between the window sill prefabricated exterior wall 10 and the building body.

One layer of floor slab reinforcement is bent outwards into a hoop and anchored into the prefabricated composite beam 30 on the window top. The bent hoop hooks the reinforcement 31 on the composite beam and the additional reinforcement 32 on the lower side of the composite beam, and then anchored inwards into the vertical folded plate 21. At the same time, two reinforcing steel bars are added to the bottom and top of the vertical folded plate 21 respectively. Finally, the cast-in-place part of the composite beam and the bathroom folded plate form a cast-in-place composite layer 40, which is then cast in-situ as a whole to form the prefabricated exterior wall node structure of the same-floor drainage of the bathroom.
[0038] In summary, the technical solution of this application has the following beneficial effects:
