[0002] In recent years, the country has vigorously promoted prefabricated buildings and intelligent construction. The precast wall is a prefabricated structure, that is, the components are industrially produced in the factory and transported to the site for direct assembly, which is more convenient, faster than the traditional cast-in-place structure, and saves the total construction period.

[0003] In order to ensure the effective connection between the precast wall and the floor structure and achieve reliable waterproof performance, a cast-in-place layer with a certain height is left between the bottom of the precast wall and the floor structure.

Detailed implementation manners

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present utility model.

[0039] In the related art, the plugging mold 2 can be made of a metal material. The plugging mold 2 can be made of materials such as aluminum or aluminum alloy. The plugging mold 2 is first connected to the floor structure 4, and then the precast wall 3 is matched with the plugging mold 2 so that the bottom of the precast wall 3 and the plugging mold 2 enclose a pouring cavity.

[0040] In order to make the installation of the precast wall 3 more efficient and convenient and ensure that the precast wall 3 is accurately positioned and does not displace, angle steel needs to be used to fix and connect the bottom of the precast wall 3 to the floor slab, and lower inclined supports are configured at the same time.

[0041] However, in this way, the plugging mold 2 mainly functions as a formwork, and the connection strength between the plugging mold 2 and the floor structure 4 is relatively low. The plugging mold 2 does not effectively fix the precast wall 3. The precast wall 3 is fixed with angle steel. Since the angle steel is heavy and different specifications and models need to be customized, it is not conducive to the popularization of technology.

[0042] In addition, when the precast wall 3 is an exterior wall, the upper and lower precast walls 3 need to be kept flush, but the precast wall 3 cannot be accurately positioned during hoisting.

[0043] The following will be combined with Figures 1 to 9 , to describe the embodiments of the present utility model.

[0044] According to an embodiment of the present utility model, on the one hand, a connector 1 for a precast wall 3 is provided. The connector 1 includes a first connecting plate 100, a second connecting plate 200, and a first pressing plate 300.

[0045] The first connecting plate 100 is adapted to be connected to the plugging mold 2. Among them, the connection between the first connecting plate 100 and the plugging mold 2 can be a fixed connection, that is, the first connecting plate 100 can be integrally formed with the plugging mold 2, or the first connecting plate 100 and the plugging mold 2 are separately formed and then connected into one body. In this way, the connection strength between the first connecting plate 100 and the plugging mold 2 is high, and the relative displacement between the connector 1 and the plugging mold 2 is not likely to occur;

[0046] The first connecting plate 100 and the plugging mold 2 can also be detachably connected. The first connecting plate 100 is configured with a connecting hole 110, and the tension structure 700 passes through the connecting hole 110 to connect with the plugging mold 2. The tension structure 700 can be structures such as bolts, screws, rivets, etc., to fix the relative positions between the first connecting plate 100 and the plugging mold 2. In this way, the first connecting plate 100 can be connected to the plugging mold 2 during on-site construction, and the installation position of the first connecting plate 100 is more flexible and more in line with the on-site construction requirements.

[0047] The second connecting plate 200 is connected to the first connecting plate 100, and the first connecting plate 100 and the second connecting plate 200 have an included angle. Specifically, the first connecting plate 100 and the second connecting plate 200 can be perpendicularly arranged to each other. Among them, the first connecting plate 100 and the second connecting plate 200 can be an integral structure. For example, a metal plate (such as a steel plate) is bent to form the first connecting plate 100 and the second connecting plate 200. At this time, the connection between the first connecting plate 100 and the second connecting plate 200 can be an arc transition; the first connecting plate 100 and the second connecting plate 200 can also be a split structure and then connected into one body by welding or other means.

[0048] The second connecting plate 200 is adapted to be connected to the floor structure 4. Among them, the floor structure 4 can be a prefabricated structure such as a floor slab. The connection between the second connecting plate 200 and the floor structure 4 can be a fixed connection, that is, the second connecting plate 200 can be prefabricated in the floor structure 4, or the second connecting plate 200 and the floor structure 4 are formed separately and then poured into one body. In this way, the connection strength between the second connecting plate 200 and the floor structure 4 is high, and the relative displacement between the connecting member 1 and the floor structure 4 is not likely to occur;

[0049] The connection between the second connecting plate 200 and the floor structure 4 can also be a detachable connection. The second connecting plate 200 is configured with a strip hole 210, and a fixing member passes through the strip hole 210 to connect with the floor structure 4. The fixing member can be structures such as expansion bolts, screws, rivets, etc., to fix the relative positions between the second connecting plate 200 and the floor structure 4. In this way, the second connecting plate 200 can be connected to the floor structure 4 during on-site construction, and the installation position of the second connecting plate 200 is more flexible and more in line with the on-site construction requirements.

[0050] The first pressing plate 300 is connected to the first connecting plate 100, and the first pressing plate 300 and the first connecting plate 100 form an included angle. Specifically, the first pressing plate 300 and the first connecting plate 100 can be perpendicularly arranged to each other. Among them, the first pressing plate 300 and the first connecting plate 100 can be of an integral structure. For example, a metal plate (such as a steel plate) is bent to form the first pressing plate 300 and the first connecting plate 100. At this time, the connection between the first pressing plate 300 and the first connecting plate 100 can be a curved transition; the first pressing plate 300 and the first connecting plate 100 can also be of a split structure and then connected into one body by means such as welding.

[0051] The first pressing plate 300 is located above at least a part of the plugging mold 2 and is used to define the relative position of the plugging mold 2 and the floor structure 4 in the vertical direction. Among them, the first pressing plate 300 is adapted to press at least a part of the plugging mold 2 against the floor structure 4. That is to say, if at least a part of the plugging mold 2 is displaced relative to the floor structure 4 in the vertical direction, it will be restricted by the first pressing plate 300. Through the setting of the first pressing plate 300, the flipping and tilting between the plugging mold 2 and the floor structure 4 can be avoided, the relative position reliability between the plugging mold 2 and the floor structure 4 can be improved, and then the relative position reliability between the precast wall 3 and the floor structure 4 can be ensured, the installation stability of the precast wall 3 can be improved, the precast wall 3 can be provided without additional fixing structures such as angle steels, the number of parts can be reduced, the standardization level can be improved, the cost can be reduced, and the technology can be easily promoted.

[0052] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 shown, the second connecting plate 200 and the first pressing plate 300 are located on opposite sides of the first connecting plate 100. Among them, the second connecting plate 200 and the first pressing plate 300 can be located on opposite sides of the first connecting plate 100 in the thickness direction of the first connecting plate 100. That is to say, the side of the first connecting plate 100 facing away from the plugging mold 2 is connected to the second connecting plate 200, and the side of the first connecting plate 100 facing the plugging mold 2 is connected to the first pressing plate 300.

[0053] In this way, the second connecting plate 200 and the first pressing plate 300 are separated by the first connecting plate 100, and the second connecting plate 200 and the first pressing plate 300 will not interfere with each other. When the second connecting plate 200 needs to be disassembled and assembled with the floor structure 4, the position of the first pressing plate 300 does not need to be considered, and the disassembly and assembly of the second connecting plate 200 are more convenient; when the first pressing plate 300 and the plugging mold 2 need to cooperate, the position of the second connecting plate 200 does not need to be considered, and the cooperation and separation between the first pressing plate 300 and the plugging mold 2 are convenient.

[0054] In some embodiments, as Figure 1 、Figure 2 and Figure 4 As shown in Figure 4 , the lower surface of the first pressing plate 300 is higher than the lower surface of the second connecting plate 200. Since the second connecting plate 200 needs to be connected to the floor structure 4, the lower surface of the second connecting plate 200 usually needs to be in contact with the floor structure 4. By setting the lower surface of the first pressing plate 300 higher than the lower surface of the second connecting plate 200, there is a spaced space between the lower surface of the first pressing plate 300 and the floor structure 4, and this spaced space can be used to accommodate the part of the plugging mold 2 located below the first pressing plate 300 (i.e., the mounting foot 23 described below).

[0055] In this way, while ensuring that the mounting foot 23 is located below the first pressing plate 300, it does not need to be inserted into the floor structure 4, and the arrangement between the mounting foot 23 and the floor structure 4 can be more convenient.

[0056] In some embodiments, as Figures 1 - 4 shown, the connecting member 1 further includes a second pressing plate 400. The second pressing plate 400 is connected to the first connecting plate 100, and there is an included angle between the second pressing plate 400 and the first connecting plate 100. The second pressing plate 400 and the first connecting plate 100 can be arranged perpendicular to each other. The second pressing plate 400 is located above the first pressing plate 300, and the second pressing plate 400 is adapted to be connected to the plugging mold 2. For example, the second pressing plate 400 is connected to the upper surface of the plugging mold 2.

[0057] Wherein, the second pressing plate 400 and the first connecting plate 100 can be an integral structure. For example, a metal plate (such as a steel plate) is bent to form the second pressing plate 400 and the first connecting plate 100. At this time, the connection between the second pressing plate 400 and the first connecting plate 100 can be an arc transition; the second pressing plate 400 and the first connecting plate 100 can also be a split structure and then connected into one body by welding or other means.

[0058] By setting the second pressing plate 400, the second pressing plate 400 and the first pressing plate 300 together play a role in defining the position of the plugging mold 2 and the floor structure 4 in the vertical direction, and can more effectively avoid problems such as the plugging mold 2 tipping over and deflecting relative to the floor structure 4, and further improve the relative position stability between the plugging mold 2 and the floor structure 4.

[0059] For example, the first pressing plate 300 can be provided with a first fixing hole 310, and a threaded fastener passes through the first fixing hole 310 to be connected to the mounting foot 23 of the plugging mold 2; the second pressing plate 400 can be provided with a second fixing hole 410, and a threaded fastener passes through the second fixing hole 410 to be connected to the upper surface of the plugging mold 2.

[0060] Among them, the first fixing hole 310 and the second fixing hole 410 can be set simultaneously, or the first fixing hole 310 can be set alone without setting the second fixing hole 410, or the second fixing hole 410 can be set alone without setting the first fixing hole 310.

[0061] In some embodiments, as Figures 1 - 4 shown, the connecting member 1 further includes a vertical guiding plate 500. The vertical guiding plate 500 is connected to the side of the second pressing plate 400 away from the first connecting plate 100. The upper surface of the vertical guiding plate 500 extends beyond the upper surface of the second pressing plate 400. The vertical guiding plate 500 is used to guide the precast wall 3 to move in the vertical direction. For example, the lower end of the vertical guiding plate 500 is connected to the side of the second pressing plate 400 away from the first connecting plate 100, and the upper end of the vertical guiding plate 500 extends upward in the vertical direction beyond the second pressing plate 400.

[0062] Among them, the vertical guiding plate 500 and the second pressing plate 400 can be of an integral structure. For example, a metal plate (such as a steel plate) is bent to form the vertical guiding plate 500 and the second pressing plate 400. At this time, the connection between the vertical guiding plate 500 and the second pressing plate 400 can be an arc transition; the vertical guiding plate 500 and the second pressing plate 400 can also be of a split structure and then connected into one body by welding or other means.

[0063] That is to say, the height of the vertical guiding plate 500 is higher than that of the plugging mold 2, the first connecting plate 100, the second pressing plate 400, etc. The thickness direction of the vertical guiding plate 500 is the horizontal direction. When the precast wall 3 descends, the precast wall 3 can abut against the side of the vertical guiding plate 500 facing away from the first connecting plate 100, and then the precast wall 3 can continue to descend along the vertical guiding plate 500, so as to ensure that the precast wall 3 is installed at a predetermined position, improve the installation accuracy of the precast wall 3, save installation time, and improve installation efficiency.

[0064] In some embodiments, as Figures 1 - 4 shown, the connecting member 1 further includes a reinforcing plate 600. The reinforcing plate 600 is connected to the first connecting plate 100 and the second connecting plate 200. There is an included angle between the first connecting plate 100 and the second connecting plate 200. Among them, the first connecting plate 100 and the second connecting plate 200 can be perpendicularly arranged to each other, the first connecting plate 100 is perpendicular to the floor structure 4, and the second connecting plate 200 is parallel to the floor structure 4. And the cross-section of the reinforcing plate 600 can be constructed as a triangle.

[0065] By providing the reinforcing plate 600, there are more force transmission paths between the first connecting plate 100 and the second connecting plate 200, the connection strength between the first connecting plate 100 and the second connecting plate 200 is increased, the relative position is more stable, and the force-bearing performance and overall performance of the connecting member 1 are improved.

[0066] Furthermore, there can be two reinforcing plates 600. The opposite sides in the width direction of the first connecting plate 100 (the width direction, the thickness direction, and the vertical direction of the first connecting plate 100 are perpendicular to each other in pairs, and the width of the first connecting plate 100 is greater than the thickness of the first connecting plate 100) are correspondingly connected to the two reinforcing plates 600 one by one. The opposite sides in the width direction of the second connecting plate 200 (the width direction, the thickness direction, and the horizontal direction of the second connecting plate 200 are perpendicular to each other in pairs, and the width of the second connecting plate 200 is greater than the thickness of the second connecting plate 200) are correspondingly connected to the two reinforcing plates 600 one by one. The force on the connecting member 1 is evenly distributed, further increasing the connection strength between the first connecting plate 100 and the second connecting plate 200, and the force-bearing performance of the connecting plate is better.

[0067] As Figures 1 - 3 and Figure 5 shown, the second connecting plate 200 is provided with a strip-shaped hole 210. Among them, the length of the strip-shaped hole 210 is greater than the width of the strip-shaped hole 210. Among them, the strip-shaped hole 210 can be an oblong hole or a rectangular hole. The connecting member 1 includes a fixing member 800. The fixing member 800 passes through the strip-shaped hole 210 and is connected to the floor structure 4. The fixing member 800 and the second connecting plate 200 can move relative to each other along the length direction of the strip-shaped hole 210. The position of the fixing member 800 in the strip-shaped hole 210 is adjustable to adjust the connection position between the fixing member 800 and the floor structure 4, and the layout is more reasonable.

[0068] In this way, during the installation process of the second connecting plate 200, the optional range of the installation position of the fixing member 800 is large, and it can avoid interference between the fixing member 800 and the floor structure 4, such as avoiding interference between the fixing member 800 and the steel bars of the floor structure 4, and the installation is more convenient.

[0069] In some embodiments, the length direction of the strip-shaped hole 210 is perpendicular to the first connecting plate 100, and the width direction of the strip-shaped hole 210 is parallel to the first connecting plate 100. At this time, the fixing member 800 can move relative to the second connecting plate 200 in a direction perpendicular to the first connecting plate 100; in some other embodiments, the length direction of the strip-shaped hole 210 is parallel to the first connecting plate 100, and the width direction of the strip-shaped hole 210 is perpendicular to the first connecting plate 100. At this time, the fixing member 800 can move relative to the second connecting plate 200 in a direction parallel to the first connecting plate 100.

[0070] In this way, the way of setting the strip-shaped hole 210 on the second connecting plate 200 is more diverse, and then the structure of the connecting member 1 is more diverse, and the connecting member 1 can be applied to different usage scenarios to meet different installation requirements and usage requirements.

[0071] It should be noted that the connecting hole 110 is configured as a round hole to fix the relative position between the first connecting plate 100 and the plugging mold 2 and prevent relative displacement between the first connecting plate 100 and the plugging mold 2.

[0072] According to an embodiment of the present invention, on the other hand, a plugging assembly is also provided, as Figures 6 - 9 shown. The plugging assembly includes a plugging mold 2 and a connecting member 1 for a precast wall according to the embodiment of the first aspect. The plugging mold 2 is connected to the connecting member 1 and is adapted to be connected to the floor structure 4. The plugging mold 2 is formed with a pouring space. The precast wall 3 descends into the pouring space to achieve on-site pouring and plug the bottom of the precast wall 3, improving the waterproof effect.

[0073] In the plugging assembly of this embodiment, through the combination of the connecting member 1 and the plugging mold 2, the connecting member 1 can fix the relative position between the plugging mold 2 and the floor structure 4 stably, not only can the bottom of the precast wall 3 be plugged, but also the relative position reliability between the precast wall 3 and the floor structure 4 can be improved.

[0074] Specifically, there can be multiple connecting members 1, and the multiple connecting members 1 are arranged at intervals along the length direction of the plugging mold 2 to increase the connection strength between the plugging mold 2 and the floor structure 4.

[0075] In some embodiments, as Figure 6 and Figure 9 shown, the plugging assembly further includes a tension structure 700. The plugging mold 2 includes a first side mold 21 and a second side mold 22. The first side mold 21 and the second side mold 22 are located on opposite sides in the thickness direction of the precast wall 3, and the first side mold 21 and the second side mold 22 are spaced apart relatively to form a pouring space. The connecting member 1 is located on the side of the first side mold 21 facing away from the second side mold 22. The tension structure 700 passes through the first connecting plate 100, the first side mold 21 and the second side mold 22. The tension structure 700 simultaneously penetrates the first connecting plate 100, the first side mold 21 and the second side mold 22 and connects the first connecting plate 100, the first side mold 21 and the second side mold 22. The first side mold 21 and the second side mold 22 are adapted to clamp the precast wall 3, and the tension structure 700 can support the precast wall 3. Among them, the tension structure 700 can be a tension screw.

[0076] For example, when the precast wall 3 is an interior wall, the structures of the first side mold 21 and the second side mold 22 can be the same; when the precast wall 3 is an exterior wall, the first side mold 21 is located inside the precast wall 3 and is connected to the floor structure 4, and the second side mold 22 is located outside the precast wall 3 and is connected to the upper part of the lower precast wall 3 to ensure the alignment of the upper and lower precast walls 3.

[0077] In this way, the first-side mold 21 and the second-side mold 22 can guide the precast wall 3, ensuring that the precast wall 3 is installed in place and facilitating the sealing of the bottom of the precast wall 3. Additionally, the tension structure 700 passes through the first connecting plate 100, the first-side mold 21, and the second-side mold 22, which can fix the relative positions of the first connecting plate 100, the first-side mold 21, and the second-side mold 22. The installation accuracy of the sealing assembly is higher, and there is no need to install them separately in pairs, reducing the number of parts, lowering costs, and simplifying the installation steps.

[0078] In some embodiments, as Figure 7 and Figure 8 shown, the sealing mold 2 is configured with mounting feet 23 that extend towards the first connecting plate 100, and the mounting feet 23 are adapted to be connected to the floor structure 4. Among them, the mounting feet 23 are provided on the first-side mold 21.

[0079] By providing the mounting feet 23, the contact area between the sealing mold 2 and the floor structure 4 can be increased, and the mounting feet 23 and the precast wall 3 are located on opposite sides of the sealing mold 2, which can prevent the mounting feet 23 from interfering with the precast wall 3 and ensure the installation convenience.

[0080] Specifically, the first pressing plate 300 is located on the upper surface of the mounting feet 23 and is used to define the relative position of the mounting feet 23 and the floor structure 4 in the vertical direction. For example, the first pressing plate 300 presses on the upper surface of the mounting feet 23.

[0081] Among them, the thickness of the mounting feet 23 is small, so the first pressing plate 300 does not need to be set too high to be located on the upper surface of the mounting feet 23. In this way, there is sufficient space above the first pressing plate 300 for arranging the second pressing plate 400.

[0082] Among them, when the mounting feet 23 move away from the floor structure 4 in the vertical direction, the upper surface of the mounting feet 23 will abut against the lower surface of the first pressing plate 300, thereby defining the relative position between the sealing mold 2 and the floor structure 4 and preventing the sealing mold 2 from flipping relative to the floor structure 4.

[0083] For example, the first-side mold 21 includes a first sealing plate 21A, mounting feet 23, and an upward flange 21B, and the second-side mold 22 includes a second sealing plate 22A, a first flange 22B, and a second flange 22C. Among them, the first sealing plate 21A and the second sealing plate 22A are opposite and spaced apart, the first sealing plate 21A and the second sealing plate 22A clamp the opposite sides of the precast wall 3, and a pouring space is formed between the first sealing plate 21A and the second sealing plate 22A.

[0084] The mounting feet 23 and the upward flanges 21B are located on the side of the first sealing plate 21A facing away from the second side mold 22. The mounting feet 23 are connected to the lower side edge of the first sealing plate 21A and are adapted to be mounted to the floor structure 4. The upward flanges 21B are connected to the upper side edge of the first sealing plate 21A. The first pressing plate 300 presses on the mounting feet 23, and the second pressing plate 400 presses on the upward flanges 21B.

[0085] The first turned-up edge 22B and the second turned-up edge 22C are located on the side of the second sealing plate 22A facing away from the first side mold 21. Among them, when the precast wall 3 is an interior wall, the first turned-up edge 22B is connected to the lower side edge of the second sealing plate 22A and is adapted to be mounted to the floor structure 4, and the second turned-up edge 22C is connected to the upper side edge of the second sealing plate 22A; when the precast wall 3 is an exterior wall, as Figure 9 shown, the first turned-up edge 22B is connected to the lower side edge of the second sealing plate 22A, the second turned-up edge 22C is connected to the upper side edge of the second sealing plate 22A, the upper half of the second sealing plate 22A is connected to the precast wall 3, and the lower half of the second sealing plate 22A is connected to the precast wall 3 of the lower layer to ensure the alignment of the precast walls 3 of the upper and lower layers.

[0086] The following takes the precast wall 3 as an exterior wall as an example to describe the installation process of the sealing assembly and the precast wall 3:

[0087] First, connect the first side mold 21 to the floor structure 4, and connect the second side mold 22 to the outer side surface of the precast wall 3 of the lower layer;

[0088] Then, the first pressing plate 300 of the connecting member 1 presses on the mounting feet 23 of the first side mold 21, and the tensioning structure 700 passes through the first connecting plate 100 of the connecting member 1, the first side mold 21 and the second side mold 22 to fix the relative positions of the first connecting plate 100, the first side mold 21 and the second side mold 22. Among them, the first pressing plate 300 can be bolted to the mounting feet 23, and the second pressing plate 400 can be bolted to the upper surface of the first side mold 21;

[0089] Then, the fixing member 800 is installed on the floor structure 4 through the elongated holes 210 of the second connecting plate 200;

[0090] Finally, the precast wall 3 descends and contacts the vertical guiding plate 500 of the connecting member 1, and descends along the vertical guiding plate 500 to the position, realizing the bottom sealing of the precast wall 3.

[0091] The following takes the precast wall 3 as an interior wall as an example to describe the installation process of the sealing assembly and the precast wall 3:

[0092] First, connect the first side mold 21 to the floor structure 4, and connect the second side mold 22 to the floor structure 4;

[0093] Then, the first pressing plate 300 of the connecting member 1 presses on the mounting feet 23 of the first side mold 21, and the tension structure 700 passes through the first connecting plate 100 of the connecting member 1, the first side mold 21 and the second side mold 22 to fix the relative positions of the first connecting plate 100, the first side mold 21 and the second side mold 22;

[0094] Then, the fixing member 800 is installed on the floor structure 4 through the strip hole 210 of the second connecting plate 200;

[0095] Finally, the precast wall 3 descends and contacts the vertical guiding plate 500 of the connecting member 1, descends along the vertical guiding plate 500 to the place, and tightens the tension structure 700 so that the first side mold 21 and the second side mold 22 clamp the precast wall 3 (as Figure 9 shown, before the tension structure 700 is tightened, the gap between the first side mold 21 and the second side mold 22 can be greater than the thickness of the precast wall 3, reducing the frictional force received when the precast wall 3 descends and facilitating the descent of the precast wall 3 to the place), realizing the bottom sealing of the precast wall 3.
