Description

Technical Field

[0001] This utility model relates to the field of precast component technology, specifically to steel cages and precast shear walls. Background Technology

[0002] Precast shear walls are concrete shear wall components that are prefabricated in a factory and then transported to the construction site for hoisting and connection. They are an important part of prefabricated concrete structure technology and are widely used in various high-rise buildings.

[0003] Currently, existing precast shear walls typically consist of two precast wall panels and a conventional steel cage. The two precast wall panels are connected by the steel cage to form an integrated precast component. During assembly, the precast shear wall needs to be placed in a preset position and concrete is poured between the two precast wall panels. In this type of precast shear wall, the lower part of the precast wall panels is prone to deformation during pouring, resulting in poor pouring reliability. Utility Model Content

[0004] In view of this, the present invention provides a steel cage and a precast shear wall to solve the problem of poor reliability in the casting of existing precast shear walls.

[0005] In a first aspect, this utility model provides a reinforcing cage for connecting adjacent leaf plates. The reinforcing cage has a first direction, a second direction, and a third direction that are perpendicular to each other. It includes: two main components spaced apart along the first direction, each main component including a first main body and a second main body connected sequentially along the second direction; a plurality of first connecting components spaced apart along the second direction at a first interval distance, the two first main bodies being connected by the plurality of first connecting components; and a plurality of second connecting components spaced apart along the second direction at a second interval distance, the two second main bodies being connected by the plurality of second connecting components; wherein the first interval distance is greater than the second interval distance.

[0006] Beneficial effects: By setting the spacing of the first connecting component to be greater than that of the second connecting component, when the two leaf plates are connected by the steel cage, the lower part of the leaf plate can be more effectively tied and fixed due to the higher density of the second connecting component. During the pouring process, even if the lower part of the leaf plate bears greater pressure, the steel cage and leaf plate can stably maintain their original state, which can effectively prevent the wall from deforming or failing after pouring, and effectively solve the problem of poor reliability of existing precast shear wall pouring.

[0007] In one alternative implementation, the main component is a steel mesh. The first connecting component and / or the second connecting component are multiple tie rods spaced apart along a third direction.

[0008] Beneficial effects: This type of steel cage structure is simple, reliable, and easy to process and manufacture.

[0009] In one alternative embodiment, the main body component includes a plurality of first reinforcing bars spaced apart along a third direction, the first reinforcing bars extending along a second direction; The first connecting component and / or the second connecting component includes a plurality of tie bars and two second reinforcing bars, the second reinforcing bars extending along a third direction and the two second reinforcing bars being spaced apart along a first direction, the plurality of tie bars being spaced apart along a third direction, and the two second reinforcing bars being connected by the plurality of tie bars.

[0010] Beneficial effects: This type of steel cage structure is simple, reliable, and easy to process and manufacture.

[0011] In one alternative embodiment, along the second direction, the first main body portion has a height dimension H1, and the second main body portion has a height dimension H2, wherein the ratio of H1 to H2 ranges from 1 to 3. And / or, along the second direction, the numerical range of the first interval distance is 300mm to 400mm, and the numerical range of the second interval distance is 150mm to 200mm.

[0012] Beneficial effects: The use of this height-to-dimensional ratio in the main body of the main component can ensure the structural tie strength of the local parts of the steel cage, while also avoiding the waste of materials caused by setting the area of ​​the second connecting component being too large.

[0013] Secondly, this utility model also provides a precast shear wall, which includes: the above-mentioned steel cage; two leaf plates, which are spaced apart along a first direction, the two leaf plates are connected by the steel cage, and at least a portion of the steel cage is located in the leaf plates.

[0014] Beneficial effects: The steel cage provides a more stable and reliable connection and fixation for the leaf plates, which can effectively reduce the amount of formwork required on the construction site and improve construction efficiency.

[0015] In one alternative embodiment, the opposing surfaces of the two blades form a casting surface, and the casting surface is provided with a plurality of first grooves and a plurality of second grooves, the first grooves extending along a second direction and the second grooves extending along a third direction.

[0016] Beneficial effects: When adjacent precast shear walls are spliced, connecting bars need to be arranged between the cast surfaces at the splicing position along the splicing direction of the precast shear walls. Due to the grooves of this type, after the connecting bars and the cast concrete have solidified, the grooves extend perpendicularly to the extension direction of the connecting bars. When the concrete and connecting bars move along the splicing direction, the grooves can resist the tendency of movement, thereby greatly increasing the stability and reliability of the precast shear walls after splicing.

[0017] In one optional embodiment, along a third direction, the portions of the casting surface near the two edges of the blade are respectively formed into first connection areas, and each of the two first connection areas is provided with a plurality of first grooves at intervals. Along the second direction, the portions of the casting surface near the edges of both sides of the blade form second connection zones, and each of the two second connection zones is provided with multiple second grooves at intervals.

[0018] Beneficial effect: By setting grooves only on the part of the casting surface near the edge of the blade, the splicing strength of the precast shear wall is improved, while avoiding the slowdown of manufacturing the precast shear wall due to setting too many grooves.

[0019] In one optional embodiment, both the first groove and the second groove are V-shaped grooves, and the depth of the first groove and the second groove ranges from 4 mm to 6 mm; and / or, along the first direction, the thickness of the blade is greater than or equal to 45 mm, and the distance between the two blades is greater than or equal to 80 mm.

[0020] Beneficial effects: This type of groove provides stronger resistance to the movement of concrete and connecting bars inside the wall. In addition, this size of groove improves the reliability of the connection and is also easier to process and manufacture.

[0021] In one alternative embodiment, the precast shear wall further includes a hoisting connector, which is disposed near the end of the reinforcing cage along the second direction. The hoisting connector is fixedly connected to the reinforcing cage and is used to connect with hoisting equipment. And / or, the precast shear wall further includes a support connector, wherein the opposing surfaces of two blades form a support surface, the support connector is disposed on the support surface and fixedly connected to the blades, and the support connector is adapted to connect with the wall support structure.

[0022] Beneficial effects: By setting up hoisting connectors, precast shear walls can be directly connected to hoisting equipment, which can greatly improve the convenience of transporting and installing precast shear walls. In addition, when installing precast shear walls, wall support structures are required to support them to prevent them from tilting during the pouring process. Setting support connectors on the leaf plates allows precast shear walls to be directly connected to the wall support structures without the need for additional connection points, which can effectively improve the assembly cycle of precast shear walls.

[0023] In one alternative embodiment, the precast shear wall further includes a plurality of positioning elements, which are spaced apart between two leaf plates. One end of the positioning element is fixedly connected to one leaf plate, and the other end of the positioning element is fixedly connected to the other leaf plate.

[0024] Beneficial effect: By setting positioning components, the distance between the two blades can be positioned, ensuring that the distance between the two blades is consistent with the design value. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The following is combined with Figures 1 to 13 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, in one aspect, a steel cage is provided for connecting adjacent leaf plates 4. The steel cage has a first direction X, a second direction Y and a third direction Z that are perpendicular to each other. The steel cage includes: two main components 1, a plurality of first connecting components 2 and a plurality of second connecting components 3. Two main body components 1 are spaced apart along a first direction X, and each main body component 1 includes a first main body portion 101 and a second main body portion 102 connected sequentially along a second direction Y. Multiple first connecting components 2 are arranged at first intervals along the second direction Y, and two first main body parts 101 are connected by multiple first connecting components 2; Multiple second connecting components 3 are arranged at second intervals along the second direction Y, and two second main body parts 102 are connected by multiple second connecting components 3; The first interval distance is greater than the second interval distance.

[0031] In this embodiment, the spacing of the first connecting component 2 is set to be greater than the spacing of the second connecting component 3. When the two leaf plates 4 are connected by the steel cage, the lower part of the leaf plate 4 can be more effectively tied and fixed due to the higher density of the second connecting component 3. During the pouring process, even if the lower part of the leaf plate 4 is subjected to greater pressure, the steel cage and leaf plate 4 can stably maintain their original state, which can effectively prevent the wall from deforming or failing after pouring. This effectively solves the problem of poor reliability in the pouring of existing precast shear walls.

[0032] The first direction refers to Figure 1 The direction of the "X" pointed to by the middle arrow, the second direction refers to Figure 1 The direction of the "Y" indicated by the middle arrow, the third direction refers to... Figure 1 The direction of "Z" indicated by the middle arrow is perpendicular to each other in the first direction X, the second direction Y, and the third direction Z. It should be understood that the introduction of the concepts of the first direction X, the second direction Y, and the third direction Z, as well as symmetrical axes, is merely for the convenience of describing spatial relationships and should not be construed as limiting the scope of the embodiments of this application. Therefore, the perpendicular relationship between the first direction X, the second direction Y, and the third direction Z can be interpreted, depending on the actual technical scenario, as the first direction X, the second direction Y, and the third direction Z representing three mutually perpendicular directions in three-dimensional space, or reasonably interpreted as a nearly perpendicular relationship between the first direction X, the second direction Y, and the third direction Z, for example, the included angles between the first direction X, the second direction Y, and the third direction Z are all within the range of 85°-95°… Any technical solution that conforms to the spirit of this utility model or achieves the technical effects described in this utility model can be considered to fall within the scope defined by the appended claims.

[0033] Specifically, there is no limitation on the specific types of the first connecting component 2 and the second connecting component 3. They can be the same components or components with different structures, as long as they can form a steel cage together with the main component 1.

[0034] In one possible implementation, such as Figure 1 and Figure 2 As shown, the main component 1 is a steel mesh 103; The first connecting component 2 and / or the second connecting component 3 are multiple tie bars 201 spaced along the third direction Z. This type of steel cage structure is simple, reliable, and easy to process and manufacture.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, the steel mesh is made up of multiple perpendicular steel bars connected together, and the tie bars are used to fix the intersection of the steel bars to form a steel cage.

[0036] Furthermore, such as Figure 2 As shown, in the same connecting assembly, the spacing between multiple tie rods 201 along the third direction Z is less than or equal to 400mm.

[0037] In one possible implementation, such as Figure 3 and Figure 4 As shown, the main component 1 includes a plurality of first steel bars 104 spaced along the third direction Z, and the first steel bars 104 extend along the second direction Y; The first connecting component 2 and / or the second connecting component 3 include a plurality of tie bars 201 and two second reinforcing bars 202. The second reinforcing bars 202 extend along the third direction Z, and the two second reinforcing bars 202 are spaced apart along the first direction X. The plurality of tie bars 201 are spaced apart along the third direction Z, and the two second reinforcing bars 202 are connected by the plurality of tie bars 201. This type of reinforcing cage structure is simple and reliable and easy to process and manufacture.

[0038] Specifically, such as Figure 3 and Figure 4 As shown, the connecting component in this embodiment is a mesh formed by connecting multiple tie bars 201 and two second reinforcing bars 202. In order to avoid a large spacing between the mesh formed by multiple tie bars 201 and two second reinforcing bars 202 in the first connecting component 2, the first connecting component 2 also includes a structural mesh 203. The structural mesh 203 is a mesh formed by connecting the ends of two reinforcing bars through tie bars. By setting the structural mesh 203 between the mesh formed by multiple tie bars 201 and two second reinforcing bars 202, the structural strength of the formed reinforcing cage is guaranteed.

[0039] Furthermore, such as Figure 4 As shown, in the same connection assembly, the spacing between multiple tie bars 201 on the second reinforcing bar 202 along the third direction Z is less than or equal to 400 mm.

[0040] In one possible implementation, such as Figure 5 As shown, along the second direction Y, the first main body 101 has a height dimension H1, and the second main body 102 has a height dimension H2. The ratio of H1 to H2 ranges from 1 to 3. The main body of the main body component 1 adopts this height dimension ratio, which can ensure the structural tie strength of the local position of the steel cage, and at the same time avoid the area where the second connecting component 3 is set being too large, thus avoiding material waste.

[0041] It should be noted that, Figure 5In the first main body 101, the distance between the two first connecting components 2 located away from the second main body 102 is small. This is the result of the arrangement to accommodate the size of the first main body 101. Since the first connecting components 2 must be provided at the edge of the first main body 101, the first connecting components 2 still need to be provided at this position when the distance between the edge of the first main body 101 and the adjacent first connecting components 2 is narrow. This does not conflict with the distance between the first connecting components 2 as defined in this application.

[0042] Preferably, such as Figure 2 As shown, the ratio of H1 to H2 is 2, meaning that the second main body 102 occupies one-third of the area of ​​the main body component 1.

[0043] In one possible implementation, along the second direction Y, the first interval distance ranges from 300mm to 400mm, and the second interval distance ranges from 150mm to 200mm.

[0044] Specifically, the first interval distance can be any value among 300mm, 330mm, 350mm, 370mm, and 400mm, or a value between any two values; the second interval distance can be any value among 150mm, 160mm, 170mm, 180mm, 190mm, and 200mm, or a value between any two values.

[0045] According to an embodiment of the present invention, on the other hand, as... Figure 6 As shown, a precast shear wall is provided, which includes: the above-mentioned steel cage and two leaf plates 4; the two leaf plates 4 are arranged at intervals along a first direction X, the two leaf plates 4 are connected by the steel cage, and at least a portion of the steel cage is located in the leaf plates 4.

[0046] The precast shear wall of this embodiment provides a more stable and reliable connection between the steel cage and the leaf plate 4, which can effectively reduce the amount of formwork required on the construction site and improve construction efficiency.

[0047] In one possible implementation, such as Figure 7As shown, the opposing surfaces of the two blades 4 form a casting surface 401. The casting surface 401 is provided with a plurality of first grooves 402 and a plurality of second grooves 403. The first grooves 402 extend along the second direction Y, and the second grooves 403 extend along the third direction Z. When adjacent precast shear walls are spliced, connecting bars need to be arranged between the casting surfaces 401 at the splicing position along the splicing direction of the precast shear walls. Due to the grooves of this type, after the connecting bars and the cast concrete have solidified, since the extension direction of the grooves is perpendicular to the extension direction of the connecting bars, when the concrete and the connecting bars move along the splicing direction, the grooves can resist the movement tendency, thereby greatly increasing the stability and reliability of the precast shear walls after splicing.

[0048] Specifically, the area where the first groove 402 and the second groove 403 are provided on the casting surface 401 is not limited. The first groove 402 and the second groove 403 can be provided in the entire area of ​​the casting surface 401, or the first groove 402 and the second groove 403 can be provided only in the area near the splicing position.

[0049] In one possible implementation, such as Figure 7 As shown, along the third direction Z, the portions of the casting surface 401 near the two sides of the blade 4 respectively form first connection areas 4011, and each of the two first connection areas 4011 is provided with a plurality of first grooves 402 at intervals. Along the second direction Y, the portions of the casting surface 401 near the edges of the blade 4 on both sides form second connection areas 4012. Each of the two second connection areas 4012 is provided with a plurality of second grooves 403 at intervals. Grooves are only provided on the portions of the casting surface 401 near the edges of the blade 4. This improves the splicing strength of the precast shear wall while avoiding the slowdown in the manufacturing speed of the precast shear wall due to the excessive number of grooves.

[0050] It should be noted that when the second connecting area 4012 overlaps with the first connecting area 4011, only the second connecting area 4012 can be provided to avoid the situation where the second groove 403 and the first groove 402 are provided in the same area at the same time, which would reduce the obstructive effect of the groove.

[0051] In addition, along the third direction Z, the ratio of the width of the first connecting area 4011 to the width of the blade 4 is not limited, and can be any value among 1, 0.8, 0.5, or any value between any two values; along the second direction Y, the ratio of the width of the second connecting area 4012 to the width of the blade 4 is not limited, and can be any value among 1, 0.8, 0.5, or any value between any two values.

[0052] In one possible implementation, such as Figure 8As shown, both the first groove 402 and the second groove 403 are V-shaped grooves. The depth of the first groove 402 and the second groove 403 ranges from 4mm to 6mm. This type of groove provides stronger resistance to the movement of concrete and connecting bars inside the wall. In addition, this type of groove improves the reliability of the connection and is also easy to process and manufacture.

[0053] It is understood that, as an alternative implementation, the first groove 402 and the second groove 403 can also be U-shaped grooves, rectangular grooves, etc., as long as they can serve as obstructions.

[0054] Specifically, such as Figure 8 As shown, in the plurality of first grooves 402 or the plurality of second grooves 403, the interval between adjacent grooves in the same connection area is 3cm to 8cm, preferably 5cm. The grooves are formed by using a metal rake to roughen the surface of the component parallel to the concrete forming the blade 4 before the concrete has completely set. The roughening time should be controlled between 25min and 35min after the concrete is laid, preferably 30min.

[0055] In one possible implementation, along the first direction X, the thickness of the blade 4 is greater than or equal to 45 mm, and the distance between the two blades 4 is greater than or equal to 80 mm.

[0056] In one possible implementation, such as Figure 9 As shown, along the second direction Y and along the third direction Z, the end face of the blade 4 is set as a rough surface. The roughness of the rough surface is not less than 4mm. The rough surface is in the form of exposed aggregate or pitted surface. The pitted surface area accounts for more than 50% of the end face area.

[0057] In one possible implementation, the precast shear wall also includes a hoisting connector. Along the second direction Y, the hoisting connector is located near the end of the reinforcing cage. The hoisting connector is fixedly connected to the reinforcing cage and is used to connect with hoisting equipment. By providing the hoisting connector, the precast shear wall can be directly connected to the hoisting equipment, which can greatly improve the convenience of transporting and installing the precast shear wall.

[0058] Specifically, the lifting connector is a lifting ring formed by bending steel bars, and the lifting connector is fixedly connected to the main component 1 of the steel cage by welding.

[0059] In one possible implementation, such as Figure 10 and Figure 11As shown, the precast shear wall also includes a support connector 5. The opposing surfaces of the two blades 4 form a support surface 404. The support connector 5 is disposed on the support surface 404 and fixedly connected to the blades 4. The support connector 5 is suitable for connection with the wall support structure. When the precast shear wall is installed, it needs to be supported by the wall support structure to prevent the precast shear wall from tilting during the pouring process. The support connector 5 on the blades 4 allows the precast shear wall to be directly connected to the wall support structure without the need for additional connection points, which can effectively improve the assembly cycle of the precast shear wall.

[0060] Specifically, such as Figure 10 and Figure 11 As shown, the support connector 5 is a flat bolt, and the plate at the root of the flat bolt is embedded in the blade plate 4. In addition, in order to improve the embedding stability of the flat bolt, a support steel bar 501 needs to be set inside the blade plate 4. The support steel bar 501 is fixedly connected to the flat bolt, thereby improving the connection strength between the flat bolt and the blade plate 4.

[0061] Furthermore, there are no restrictions on the specifications and dimensions of the flat bolts and the supporting steel bars 501; they can be selected according to the dimensions of the precast shear wall.

[0062] Preferably, such as Figure 10 As shown, the height of the flat bolt is less than or equal to 35mm, the width of the plate at the root of the flat bolt is in the range of 45mm to 55mm, preferably 50mm, and the diameter of the stud is in the range of 15mm to 25mm, preferably 20mm. In addition, such as Figure 11 As shown, the flat bolt is simultaneously connected to two spaced-apart supporting steel bars 501. The length of the supporting steel bars 501 ranges from 300mm to 400mm, preferably 350mm.

[0063] In one possible implementation, such as Figure 6 As shown, along the first direction X, the distance from the casting surface 401 of the blade 4 to the main component 1 is H3, and the value of H3 is greater than or equal to 15mm; along the first direction X, the distance from the supporting surface 404 of the blade 4 to the first connecting component 2 or the second connecting component 3 is H4, and the value of H4 is greater than or equal to 12mm.

[0064] In one possible implementation, such as Figure 12 As shown, the precast shear wall also includes multiple positioning elements 6, which are spaced apart between two leaf plates 4. One end of the positioning element 6 is fixedly connected to one leaf plate 4, and the other end of the positioning element 6 is fixedly connected to another leaf plate 4. By setting the positioning elements 6, the distance between the two leaf plates 4 can be positioned, so that the distance between the two leaf plates 4 can be kept consistent with the design value.

[0065] Specifically, there is no limitation on the specific type of positioning component 6; it can be a steel bar or a limiting rod.

[0066] Furthermore, in use, one end of the positioning member 6 is inserted into and fixed in one of the blades 4 at a preset depth. When the positioning member 6 is connected to the other blade 4, before the other blade 4 is completely solidified, the other end of the positioning member 6 is inserted into the blade 4, and the end of the positioning member 6 is flush with the support surface 404 of the blade 4. At this time, the distance between the two blades 4 can be effectively controlled.

[0067] In addition, such as Figure 12 As shown, a support leg is provided at one end of the positioning component 6. When the positioning component 6 is connected to the first blade 4, the support leg can effectively prevent the positioning component 6 from tipping over.

[0068] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
