Description

Technical Field

[0001] The invention relates to the technical field of building auxiliary components, and in particular to a reinforced concrete shear wall with built-in positioning prefabricated parts. Background Art

[0002] The use of prefabricated parts reduces dangerous operations such as welding and cutting at the construction site, reducing safety risks during the construction process. At the same time, the quality of prefabricated parts can be better controlled and inspected in the factory to ensure that they meet relevant safety standards and requirements, thereby improving the safety and reliability of the shear wall structure.

[0003] The size and specifications of prefabricated shear walls vary according to the requirements of the building design. Some may be several meters long and several meters high. The corresponding hoisting structure usually uses wire ropes, hooks and other connection methods. During the hoisting process, these connection parts are connected to the hooks embedded in them, and the hooks are connected to a single steel bar. During the hoisting process, the corresponding steel bars have to withstand huge tensile forces. The connection between the hoisting parts and the single steel bar embedded parts is prone to damage to the connection parts during the hoisting process, such as deformation of the steel bar embedded parts, cracking of the connection welds, damage to the concrete around the steel bar embedded parts, such as cracking and peeling, and damage to the hoisting parts themselves, such as deformation and fracture. On the one hand, it may affect the connection effect with the subsequent structure, resulting in a loose connection and affecting the stability of the overall structure; on the other hand, it may cause the concrete around the embedded parts to be squeezed or cracked, destroying the integrity of the concrete.

[0009] A shear wall body, wherein the shear wall body comprises an outer facing surface located at the outermost side, an insulation layer is arranged on the inner side of the outer facing surface, and a load-bearing layer is arranged on the inner side of the insulation layer;

[0010] A steel mesh is arranged on the inner side of the load-bearing layer, and the steel mesh is connected to the load-bearing layer, the thermal insulation layer and the outer finishing surface through an externally arranged positioning part. The positioning part includes a positioning seat connected to the load-bearing layer and the thermal insulation layer, a positioning piece is fixedly connected to the bottom end of the positioning seat, and a fixing piece and a connecting piece are respectively arranged on the outer side of the positioning piece. The fixing piece, the connecting piece and the positioning piece together constitute a whole.

[0011] Wherein, the side of the connecting piece is provided with a side plate which is convenient for lifting.

[0012] Furthermore, the steel mesh includes longitudinal steel bars that transversely penetrate the load-bearing layer, and transverse steel bars are arranged at the upper and lower ends of the outer sides of the longitudinal steel bars. The connection between the transverse steel bars and the longitudinal steel bars is connected to the inner wall of the positioning member.

[0013] Furthermore, the inner wall of the insulation layer is evenly provided with slot one, the inner wall of the exterior surface is evenly provided with slot two, the positions of slot one and slot two overlap, and the positioning seat can pass through slot one and slot two, so as to facilitate the installation of the inclined support structure.

[0014] Furthermore, the inner wall of the insulation layer is evenly provided with slot one, the inner wall of the exterior surface is evenly provided with slot two, the positions of slot one and slot two overlap, and the positioning seat can pass through slot one and slot two, so as to facilitate the installation of the inclined support structure.

[0018] Beneficial Effects

[0019] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] The present invention is provided with a positioning part, which not only realizes the positioning and fixation of the steel mesh, but also forms the steel mesh and the positioning part into an integral structure, thereby avoiding damage to the shear wall body caused by the concentration of hoisting stress, and also limits the side support of the shear wall body after hoisting, thereby ensuring the uniform solidification of concrete during the pouring process before hoisting, the uniform force of the device during the hoisting process, and the stable support of the device after hoisting.

After the concrete is poured and solidified, the overall structure formed by the side panel and the positioning piece and the fixing piece, when hoisting, the pulling force of the traction rope on the hoisting port of the hoisting will be evenly dispersed in the overall structure composed of the connecting piece, the positioning piece and the fixing piece, thereby avoiding the problem in the prior art that the hoisting piece is only fixed to a single steel bar, and the shear wall body is easily damaged due to stress concentration during the hoisting process.

[0022] The present invention is provided with a positioning piece, and a positioning groove 2 is opened at a horizontal position in the middle of the positioning block, and a horizontal steel bar is penetrated inside the positioning groove 2.

The horizontal steel bar and the longitudinal steel bar can be accurately inserted therein, and positioned under the restriction of the middle part of the positioning groove 2 and the positioning groove 1. At the same time, due to the large size of the side opening, concrete can be poured into the positioning groove 1 and the positioning groove 2 during the subsequent concrete pouring process, so as to fix the horizontal steel bar of the positioning groove 2 and the longitudinal steel bar of the positioning groove 1, so that the positioning block and the horizontal steel bar and the longitudinal steel bar form a fixed integral structure.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0032] Example:

[0033] See also Figure 1-Figure 5 The present invention provides a technical solution for reinforced concrete shear wall with built-in positioning prefabricated parts: Figure 1 The shear wall body 1 includes a load-bearing layer 11, an insulation layer 12 and an exterior finish 13. The load-bearing layer 11, the insulation layer 12 and the exterior finish 13 are arranged in sequence from the inside to the outside. Similar to the prior art, the steel mesh 2 is installed and fixed in the mold and then poured. After the pouring is successful, the bottom surface is the load-bearing layer 11, the middle structure is the insulation layer 12, and the top structure is the exterior finish 13.

[0034] refer to Figure 2 and Figure 3 The steel mesh 2 includes transversely placed longitudinal steel bars 22 and transverse steel bars 21 placed perpendicular thereto. A plurality of longitudinal steel bars 22 and transverse steel bars 21 together constitute the steel mesh 2. Due to the characteristics of the steel bars themselves, the staff is required to install a positioning structure to fix the steel mesh 2. The present invention has embedded a positioning part 3, which can position the steel mesh 2 while improving the lifting effect.

[0035] like Figure 3 and Figure 4 As shown, the positioning part 3 includes a horizontal steel bar 21 for positioning the horizontal steel bar 21 and the longitudinal steel bar 22 of the steel mesh 2, and a positioning seat 32 is fixedly connected to the top of the horizontal steel bar 21. The positioning seat 32 can penetrate the thermal insulation layer 12 and the outer facing 13. One end of the positioning seat 32 passes through the notch 121 of the thermal insulation layer 12 and the notch 2 131 of the outer facing 13, and is flush with the surface of the outer facing 13. After the pouring is completed, the positioning seat 32 flush with the surface of the outer facing 13 will not be affected by the pouring of concrete. After the hoisting is completed, a diagonal brace can be installed inside it to support its side and avoid the later opening of the hole to the main shear wall The damage caused by the overall structure of the body 1 is prevented. At the same time, a slot is provided on the inner side of the positioning seat 32. The slot limits the diagonal rod fixer to avoid the deviation of the diagonal rod's own structure during installation, resulting in unstable supporting effect. The bottom end of the positioning piece 31 is also provided with a slot identical to the positioning seat 32. The bottom end of the positioning piece 31 is flush with the mold surface, and the positioning piece 31 will not deviate under the gravity of the steel mesh 2. Therefore, during the concrete pouring process, the slot at the bottom end of the positioning piece 31 will not be affected by the pouring concrete. When the diagonal rod is installed later, it corresponds to the slot of the positioning seat 32 to achieve uniform supporting force.

[0036] refer to Figure 2 , Figure 3 and Figure 4The side of the positioning member 31 is fixedly connected with a fixing member 33, and the other end of the fixing member 33 is fixedly connected with the side of another positioning member 31. The positioning member 31 includes a positioning block 311, and a second positioning groove 315 is provided at a horizontal position in the middle of the positioning block 311. A horizontal steel bar 21 is provided inside the second positioning groove 315. Two positioning grooves 312 are symmetrically provided inside the positioning block 311 with the second positioning groove 315 as the center. The opening sizes of both ends of the second positioning groove 315 and the first positioning groove 312 are larger than the size of the middle part. The second positioning groove 315 and the first positioning groove 312 are both set to be two funnel-shaped grooves symmetrically connected. The open groove is outward and its size is larger than that of the transverse reinforcement 21 and the longitudinal reinforcement 22. The transverse reinforcement 21 and the longitudinal reinforcement 22 can be accurately inserted therein and positioned under the restriction of the middle of the positioning groove 2 315 and the positioning groove 1 312. At the same time, due to the larger size of the side opening, concrete can be poured into the positioning groove 1 312 and the positioning groove 2 315 during the subsequent concrete pouring process, so as to fix the transverse reinforcement 21 by the positioning groove 2 315 and the longitudinal reinforcement 22 by the positioning groove 1 312, so that the positioning block 311 and the transverse reinforcement 21 and the longitudinal reinforcement 22 form a fixed integral structure.

[0037] refer to Figure 3 , Figure 4 and Figure 5 A fixing piece 33 is symmetrically fixed on one side of the opening of the positioning groove 312 on the side of the positioning block 311. The fixing piece 33 includes a fixing plate 331 fixedly connected to the side of the positioning block 311, and a limiting groove 332 is fixedly connected to the middle of the fixing plate 331. The two limiting grooves 332 are fixedly connected to the opposite sides of the limiting rings 333. The limiting rings 333 are set to be semicircular, which can provide certain support for the horizontal steel bar 21 inserted therein, and the two limiting rings 333 do not fit together, and there is a gap between them to facilitate the entry of concrete, so as to ensure that the fixing piece 33 fixes the positioning piece 31 while realizing multiple positioning of the horizontal steel bar 21.

[0038] The height dimension of the fixing plate 331 is smaller than the height dimension of the positioning block 311. During the concrete pouring process, there is no need to adjust the different directions and heights in the cavity surrounded by the fixing plate 331. The concrete can also be evenly distributed during the vibration process, so that the concrete can wrap the fixing member 33 in all directions. The concrete can enter the positioning groove 1 312 from the cavity surrounded by the fixing plate 331. After the concrete solidifies, the positioning member 31 and the fixing member 33 also become an integral structure. When the concrete solidifies in the positioning groove 1 312, the positioning groove 2 315, and the limiting groove 1 332, it will be in close contact with and bonded to the hole wall. Due to the relatively closed environment in the positioning groove 1 312, the positioning groove 2 315, and the limiting groove 1 332, the concrete is constrained by the hole wall during the solidification process, and its own shrinkage is subject to certain restrictions, which makes the pressure distribution between the concrete and the hole wall more uniform, which is conducive to forming a better bonding effect. In addition, the concrete will fill the irregular shaped space in the hole to form a mechanical bite-like effect. At the same time, the solidification of the concrete and the side of the fixing plate 331 can better connect the plate and adjacent structural members into a whole, thereby improving the spatial stability and collaborative working performance of maintaining the entire structure.

[0039] like Figure 5 The limiting groove 1 332 and the positioning groove 2 315 shown are used to position the transverse steel bar 21. A longitudinal steel bar 22 is arranged in the cavity surrounded by the two fixing plates 331. Both ends of the longitudinal steel bar 22 pass through the positioning groove 1 312 and then pass through the limiting groove 343 of the connecting member 34. The connecting member 34 is located on the side of the opening of the positioning groove 2 315 on the side of the positioning block 311, and the positioning block 311 is symmetrically provided with side grooves 313 with the positioning groove 2 315 as the center. The size of the side of the side groove 313 close to the center of the connecting plate 341 is larger than the size of the side of the side groove 313 away from the center of the connecting plate 341. The connecting member 34 can Directly inserted into it, the inner side of the side groove 313 is set to a right-angled trapezoid shape, one side of the connecting plate 341 of the connecting piece 34 is fitted with one side of the side groove 313, and the side plate 344 fixed on the side of the rear connecting plate 341 is successfully completed. At this time, it is completely located outside the side groove 313, and the longitudinal steel bars 22 located in the cavity surrounded by the fixing plate 331 can limit the connecting piece 34 and the positioning piece 31 inserted therein, so that the transverse steel bars 21 and the fixing piece 33 fixed by the concrete can fix the connecting piece 34 and the positioning piece 31, thereby connecting the positioning piece 31, the fixing piece 33 and the connecting piece 34 into a whole.

[0040] like Figure 3 and Figure 5As shown, the connecting member 34 also includes a second limiting groove 342 opened in the middle of the connecting plate 341, and the second limiting groove 342 is used to position the longitudinal steel bar 22 not placed in the cavity of the fixing member 33, and the third limiting groove 343 is symmetrically distributed with the second limiting groove 342 as the center, and the longitudinal steel bar 22 placed in the cavity of the fixing member 33 is positioned by the third limiting groove 343, and the position of the limiting groove 343 and the second limiting groove 342 near the center of the steel mesh 2 are both opened as funnel-shaped grooves, so as to fix multiple longitudinal steel bars 22 and the connecting member 34. Therefore, while the positioning member 31 positions the connection between the transverse steel bar 21 and the longitudinal steel bar 22, it also connects multiple positioning members 31 through the set fixing member 33 and the connecting member 34, so that the steel mesh 2 and the positioning part 3 constitute a complete main structure.

[0041] refer to Figure 2 , Figure 3 and Figure 5 The side panels 344 fixedly connected on both sides of the connecting plate 341 are arranged on the outside of the positioning block 311, and the side panels 344 are symmetrically provided with lifting openings 345. The spacing between the lifting openings 345 is equal to the diameter of the horizontal reinforcement 21. The horizontal reinforcement 21 will not interfere with it when the traction rope passes through it, and the length of the side panels 344 is less than the exposed length of the horizontal reinforcement 21. It will not interfere with the welded horizontal reinforcement 21 during the subsequent structural superposition process. After the concrete is poured and solidified, the integral structure formed by the side panels 344, the positioning members 31 and the fixing members 33, when hoisting, the pulling force of the traction rope on the lifting openings 345 of the hoisting will be evenly dispersed in the integral structure formed by the connecting members 34, the positioning members 31 and the fixing members 33, avoiding the problem in the prior art that the lifting members are only fixed to a single reinforcement member, and the shear wall body 1 is easily damaged due to stress concentration during the hoisting process.

[0042] By providing the positioning portion 3, not only the positioning and fixation of the steel mesh 2 is achieved, but the steel mesh 2 and the positioning portion 3 are also formed into an integral structure, thereby avoiding damage to the shear wall body 1 caused by stress concentration during lifting, and limiting the side supports of the shear wall body 1 after lifting, thereby ensuring the uniformity of concrete solidification during the pouring process before lifting, uniform force on the device during lifting, and stable support of the device after lifting.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
