Description

Technical Field

[0001] This application relates to the field of precast shear wall production molding technology, specifically to a modular assembly precast shear wall molding mold and its molding method. Background Technology

[0002] Precast shear walls are reinforced concrete shear wall components manufactured in a factory and assembled on-site, widely used in prefabricated buildings. Precast shear walls typically feature double-sided reinforcement to meet requirements for seismic ductility, bending resistance, and shear strength. During factory production, after casting, the precast shear wall has exposed reinforcing bars on all four sides. These exposed bars are connected to the reinforcing bars of floor slabs, beams, or other walls through welding or lap splicing, forming rigid nodes to ensure structural integrity. Chinese patent CN108360712A, published on August 3, 2018, discloses a prefabricated reinforced concrete shear wall. This precast shear wall not only has reinforcing bars exposed on all four sides of the concrete surface, but also has a concrete support leg on one side, with reinforcing bars also exposed on the two sides of the support leg. Such components require very high-quality molding molds during factory production, especially where the reinforcing bars protrude from the concrete surface. Improper handling can easily lead to grout leakage, resulting in an uneven concrete surface, affecting product quality, and also causing the molding mold to become contaminated and difficult to clean. If the support legs are not handled properly, it can easily cause difficulties in demolding, leading to damage to the molding die.

[0003] The existing production method mainly uses perforated steel plates to create the integral forming molds for the aforementioned precast shear walls. The perforations serve as channels for the reinforcing bars to extend. The perforated steel plate forming molds are typically single or rigid structures composed of a few parts. This leads to several problems: 1. Rigid constraints are formed on at least some of the holes or corners of the forming mold. When the steel plate or reinforcing bar gets stuck in a hole, the demolding force cannot be released through local deformation, resulting in demolding difficulties and potentially causing mold deformation or damage to the precast component. 2. Perforated steel plates have poor adaptability. If the dimensions of the precast shear wall change, the mold needs to be remade, resulting in a low turnover rate for each set of forming molds and increased production costs for precast components. 3. Perforated steel plates require customization, leading to high mold manufacturing costs and long production cycles, which affects the production efficiency of precast components. Furthermore, when using perforated steel plates as forming molds, the reinforcing bars need to be inserted through the perforations during production, resulting in low production efficiency and slow construction speed.

[0004] In some designs, the shear wall formwork is equipped with reinforcement gaps or vertical grooves on the side formwork. To facilitate the binding of the reinforcement bars inside the formwork, the double-sided reinforcement bars of the shear wall body are usually allowed to pass through a reinforcement gap or vertical groove. The space reserved in the reinforcement gap or vertical groove is relatively large. Before pouring, the reinforcement gap or vertical groove needs to be sealed with a sealing device to prevent grout leakage. However, the use of a large number of sealing devices increases the production cost of precast components. Utility Model Content

[0005] In view of this, the embodiments of this specification provide a modular assembly prefabricated shear wall forming mold and its forming method. The forming mold adopts an assembly-based design concept, which can effectively improve production efficiency, reduce costs, and has stronger adaptability and more turnover times.

[0006] Specifically, the embodiments in this specification provide the following technical solutions:

[0007] This specification first provides a modularly assembled precast shear wall forming mold, including a bottom mold platform and a lower long strip module, a side assembly module, and an upper long strip module that are supported on the bottom mold platform and assembled sequentially from bottom to top. The side assembly module includes multiple single-sided side molds and corner side molds that are connected sequentially by bolts along the circumference of the shear wall. The single-sided side mold includes a rectangular inner template and an upper wall panel, a lower wall panel, and two side wall panels arranged around the inner template. The inner template is arranged to fit the shear wall. The side wall panels are provided with first connecting holes for bolt connection. The upper wall panel has an upper through-rib notch extending downward to the side template, and the lower wall panel has a lower through-rib notch extending upward to the side template. The upper through-rib notch and the lower through-rib notch are arranged opposite each other in the longitudinal direction.

[0008] To optimize the above solution, the following technical measures were also adopted:

[0009] In one embodiment, the side assembly module further includes several adjusting clips, which are placed between the side walls of two adjacent side molds in the plurality of single-sided side molds and corner side molds. The adjusting clips are provided with second connecting holes for bolt connection.

[0010] In one embodiment, the adjusting clip includes single-plate clips and / or combined clips. The single-plate clips are adapted to rest against adjacent single-sided molds or between single-sided molds and corner molds, either individually or in groups. The combined clips have the same structure as the single-sided molds and are adapted to rest against adjacent single-sided molds or between single-sided molds and corner molds, individually.

[0011] In one embodiment, the upper opening of the upper through-rib notch penetrates the upper wall panel both inside and out, and the lower opening of the lower through-rib notch penetrates the lower wall panel both inside and out.

[0012] In one embodiment, both the upper and lower through-rib openings are U-shaped openings, and the upper and lower through-rib openings are located in the center of the single-sided mold in the lateral direction.

[0013] In one embodiment, both the upper and lower elongated modules include several elongated steel plates and right-angled steel plates distributed along the outer perimeter of the shear wall, wherein the elongated steel plates correspond to the single-sided side molds and the right-angled steel plates correspond to the corner side molds.

[0014] In one embodiment, the side assembly module is connected to both the lower and upper long strip modules by bolts.

[0015] In one embodiment, one end of the shear wall is equipped with a support leg, and the corner side mold includes an outward convex corner side mold and an inward concave corner side mold. The multiple single-sided side molds, the outward convex corner side molds and the inward concave corner side molds together enclose the shape of the shear wall with the support leg.

[0016] In addition, this specification also provides a molding method for a prefabricated shear wall molding die based on the above-mentioned modular assembly, including the following steps:

[0017] S1. Arrange the long strip modules on the bottom formwork platform according to the shape of the shear wall;

[0018] S2. Tie the lower layer of steel reinforcement mesh of the shear wall onto the lower long strip module;

[0019] S3. Assemble the side assembly module on the lower long strip module, so that the lower layer of steel bars of the wall can pass through the bottom through bar notch of the single side module. At the same time, connect the single side module and the corner side module in sequence with bolts along the circumference of the shear wall.

[0020] S4. Tie the upper layer of steel mesh of the shear wall, so that the upper layer of steel bars of the wall can pass through the upper through bar notch of the single side formwork;

[0021] S5. Assemble the long strip module on top of the side assembly module;

[0022] S6. Concrete for pouring shear walls;

[0023] S7. Remove the formwork when the concrete strength meets the requirements for demolding.

[0024] Preferably, in S3, a side assembly module is formed by combining single-sided molds of various standard sizes and corresponding corner side molds, so that the size of the side assembly module is aligned with the lower strip module.

[0025] Compared with the prior art, the beneficial effects that at least one technical solution adopted in the embodiments of this specification can achieve include at least:

[0026] 1. This application adopts a modular approach, designing the side mold of the shear wall mold as a combination of multiple single-sided side molds and corner side molds. Each single-sided side mold is independently provided with a through-beam notch for shear wall reinforcement to pass through, preventing local reinforcement from getting stuck and affecting the overall demolding of the precast component. Furthermore, the reinforcement is passed through the through-beam notch, which is simpler to operate and more efficient in arranging shear wall reinforcement than the through-beam hole method of plugging.

[0027] 2. Single-sided side molds can be made according to standardized dimensions. Their length can be selected according to the spacing requirements of the wall reinforcement, thereby increasing the applicability of the mold. At the same time, the standardization of single-sided side mold dimensions can also increase the turnover rate of the side mold and reduce the cost of the side mold.

[0028] 3. This application uses the upper and lower through-bar notches formed on the side formwork as the bar protrusion points, instead of using the reserved gaps formed between adjacent single-sided side formwork as the bar protrusion points. The gap between the exposed steel bars and the through-bar notches is very small, and there is no need to use sealing parts to seal the gaps, thus reducing the production cost of shear walls.

[0046] This specification presents a modular assembly precast shear wall forming mold and its forming method, aiming to solve the problems of easy jamming during demolding and low mold turnover caused by the rigid constraint relationship between the reinforcing bars in existing integral or partially split shear wall molds, as well as the problems of large gaps at the reinforcing bar parts, requiring a large number of sealing parts and resulting in high production costs of precast components. It can not only effectively prevent the phenomenon of local reinforcing bar jamming, but also facilitate demolding, increase the mold turnover rate, and reduce the use of a large number of sealing parts such as foam plugs, thereby reducing the production cost of precast components.

[0047] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings. Example

[0048] like Figures 1 to 3 As shown, this embodiment first provides a modular assembly prefabricated shear wall forming mold. Here, a shear wall mold with legs is used as an example for the scheme description. In fact, the mold can be adapted to the shape of the shear wall. The shear wall can also be a rectangular shear wall or a shear wall of other shapes, which is not limited here.

[0049] The shear wall forming mold includes a bottom mold platform 1 and a lower elongated module 2, a side assembly module 3, and an upper elongated module 5, which are supported on the bottom mold platform 1 and assembled sequentially from bottom to top. These three parts constitute the main body of the mold. The main function of the lower elongated module 2 is to position the bottom of the side assembly module 3, and the main function of the upper elongated module 5 is to position the top of the side assembly module 3. These three modules can be assembled into one unit by bolt connection or by other detachable methods. The side assembly module 3 includes multiple single-sided side molds 31 and corner side molds 32 connected sequentially by bolts along the circumference of the shear wall. The single-sided side molds 31 are manufactured to standardized dimensions, with their lateral lengths typically using standard sizes such as 200mm, 180mm, 150mm, 120mm, or 100mm, depending on the spacing requirements of the wall reinforcement. Standardization of the single-sided side mold 31 dimensions increases the turnover rate of the side molds and reduces their cost. The single-sided side mold 31 is generally box-shaped with one side opening, specifically including a rectangular inner template 314 and upper wall panels 311, lower wall panels 312, and two side wall panels 313 arranged around the inner template 314, as shown in the figure. Regarding mold 31, the side closer to the mold cavity, i.e., the shear wall component, is the inner side, and the side farther from the mold cavity is the outer side. The inner template 314 mentioned here is located at the innermost side of the single-sided mold 31. In other words, the inner template 314 is arranged to fit the shear wall. The side wall plate 313 is provided with a first connecting hole 319 for bolt connection. Here, the first connecting hole 319 is an elongated hole extending in the longitudinal direction. The upper wall plate 311 is provided with an upper through-rib notch 317 extending downward to the side template, and the lower wall plate 312 is provided with a lower through-rib notch 318 extending upward to the side template. The upper through-rib notch 317 and the lower through-rib notch 318 are arranged opposite each other in the longitudinal direction.

[0050] In this embodiment, the side mold of the shear wall is designed to be assembled by bolting together multiple modular single-sided side molds 31 and corner side molds 32. Each single-sided side mold 31 has an independent notch for the shear wall reinforcement to pass through. During mold installation and component demolding, the single-sided side mold 31 can be disassembled individually without affecting the other single-sided side molds 31 in the side assembly module 3. This avoids rigid constraints between the various reinforcement passing parts, holes, or corners on the side mold, preventing local reinforcement jamming and causing difficulties in demolding the precast component. Furthermore, passing reinforcement through the notch is simpler to operate and more efficient in arranging the shear wall reinforcement than passing reinforcement through holes using an insertion method. Furthermore, this embodiment uses upper and lower through-bar notches formed on the inner formwork 314 as the rebar protrusion points, instead of using reserved gaps formed between adjacent single-sided formworks. This results in very small gaps between the exposed rebars and the through-bar notches, eliminating the need for sealing components and thus reducing the production cost of the shear wall. Additionally, the single-sided formwork 31 is manufactured to standardized dimensions, and its lateral length can be selected according to the spacing requirements of the wall rebars, thereby increasing the applicability of the formwork, improving the turnover rate of the side formwork, and reducing the cost of the side formwork, as disclosed above.

[0051] like Figure 3 As shown, in this embodiment, the upper opening of the upper through-bar notch 317 penetrates the upper wall panel 311 both inside and out, and the lower opening of the lower through-bar notch 318 penetrates the lower wall panel 312 both inside and out. During component construction, by aligning the component's reinforcing bars with the openings and placing them into the notches, the reinforcing bars can be passed out from the corresponding through-bar notches. Compared to inserting reinforcing bars into through-bar holes, this method is simpler and more efficient in shear wall reinforcement arrangement.

[0052] Preferably, both the upper through-rib notch 317 and the lower through-rib notch 318 are U-shaped notches, and the upper through-rib notch 317 and the lower through-rib notch 318 are arranged in the center of the single-sided side mold 31 in the lateral direction.

[0053] In this embodiment, the corner side mold 32 includes an outwardly convex corner side mold 321 and an inwardly concave corner side mold 322. The plurality of single-sided side molds 31, the outwardly convex corner side mold 321 and the inwardly concave corner side mold 322 together enclose the shape of the shear wall with legs. The outwardly convex corner side mold 321 is located at the four corners of the shear wall and / or the top corner of the legs, while the inwardly concave corner side mold 322 is located at the bottom corner of the legs, that is, at the connection angle between the legs and the shear wall.

[0054] Although the length of the single-sided formwork 31 is available in various dimensions, which can accommodate adjustments to the wall size on a large scale, it cannot solve the problem of fine adjustments. For example, in some areas, the ends of the shear wall or the edges of openings require reinforcement densification. In this case, the dimensions of the side assembly module 3 need to be finely adjusted to accommodate changes in the spacing of the wall reinforcement and / or changes in the wall size.

[0055] Therefore, such as Figures 3 to 5 , Figure 8 As shown, in this embodiment, the side assembly module 3 further includes several adjusting clips 4. The several adjusting clips 4 are placed between the side wall plates of multiple single-sided side molds 31 and corner side molds 32. Each adjusting clip 4 is placed between the side walls of two adjacent side molds in the multiple single-sided side molds and corner side molds. The adjusting clip 4 is provided with a second connecting hole for bolt connection. Preferably, the second connecting hole is an elongated hole extending in the longitudinal direction. After the side assembly module 3 is installed in place, the second connecting hole on the adjusting clip 4 and the first connecting hole 319 on the side wall plate 313 of the single-sided side mold 31 are aligned and fastened together by bolts passing through them. Preferably, the adjusting clip 4 is aligned with the side wall plate 313 of the single-sided mold 31 and / or the corner mold 32. The inner side wall of the adjusting clip 4 is aligned with the inner template 314 of the single-sided mold 31. The upper end of the adjusting clip 4 is aligned with the top surface of the upper wall plate 311 of the single-sided mold 31, and the lower end is aligned with the bottom surface of the lower wall plate 312 of the single-sided mold 31. The side wall plates 313 of adjacent single-sided molds abut against each other and are fastened together with bolts.

[0056] Specifically, such as Figure 4 and Figure 5 As shown, the adjusting clip 4 here includes single-plate clips 41 and / or combined clips 42. The single-plate clips 41 are suitable for individually or in groups to rest against adjacent single-sided molds 31 or between a single-sided mold 31 and a corner mold 32. The thickness of the single-plate clips 41 varies, such as 8mm, 10mm, and 12mm. A single-plate clip 41 used alone can achieve millimeter-level size adjustment. Multiple single-plate clips 41 used in combination can solve size adjustments within, for example, 50mm. For example, two 10mm clips combined together are equivalent to a 20mm thick clip. The combined use of clips improves their versatility. Size adjustments between 50mm and 100mm require the use of combined clips 42. The combined clips 42 have the same structure as the single-sided molds 31. The combined clips 42 are suitable for individually resting against adjacent single-sided molds 31 or between a single-sided mold 31 and a corner mold 32. Specifically, as... Figure 5As shown, the combined clamping piece 42 is box-shaped and is also composed of side templates, upper wall panels, lower wall panels and two side wall panels. Since no steel bars pass through the side templates in the clamping piece, the side templates do not need to be opened or have notched structures. The clamping piece does not need to be connected to the upper long strip module 5 and the lower long strip module 2. Therefore, the upper wall panels and lower wall panels of the combined clamping piece do not need to be opened. However, a second connecting hole needs to be opened on the side wall panels for fastening connection with the adjacent single-sided side template 31.

[0057] In this embodiment, both the upper elongated module 5 and the lower elongated module 2 include several elongated steel plates and right-angled steel plates distributed along the outer perimeter of the shear wall. The elongated steel plates correspond to the single-sided side mold 31, and the right-angled steel plates correspond to the corner side mold 32. Specifically, the lower wall plate 312 of the single-sided side mold 31 presses against the corresponding elongated steel plate in the lower elongated module 2. Similarly, the upper wall plate 311 of the single-sided side mold 31 presses against the corresponding elongated steel plate in the upper elongated module 5.

[0058] More specifically, taking the following long strip module 2 as an example, such as Figure 6 As shown, the lower elongated module 2 includes four sets of lower elongated steel plates 21, four sets of lower right-angled steel plates 22, and two sets of lower support leg steel plates 23. The lower elongated steel plates 21 include two sets of opposing longitudinal steel plates and two sets of opposing transverse steel plates. One set of transverse steel plates defines two opposing support leg mounting slots. The two sets of lower support leg steel plates 23 are respectively placed within the two support leg mounting slots. The four sets of lower right-angled steel plates 22 are located at the four corners of the shear wall. In some embodiments, the upper elongated module 5 and the lower elongated module 2 have the same structure, which will not be described in detail here.

[0059] More specifically, such as Figure 6 As shown, in the single-sided mold 31, the lower wall plate 312 is also provided with a lower connecting hole 316, and the lower elongated module 2 is provided with a lower positioning hole 24 that mates with the lower connecting hole 316. The lower positioning hole 24 is a threaded hole. The single-sided mold 31 is positioned on the lower elongated module 2 by bolts passing through the lower connecting hole 316 and the lower positioning hole 24. Similarly, in the single-sided mold 31, the upper wall plate 311 is provided with an upper connecting hole 315, and the upper elongated module 5 is provided with an upper positioning hole that mates with the upper connecting hole 315. The upper positioning hole can be configured to have a smooth inner wall. The upper elongated module 5 is locked on the single-sided mold 31 by bolts and nuts passing through the upper positioning hole and the upper connecting hole 316.

[0060] More specifically, the convex angle side mold 321 includes two side wall plates arranged at right angles in a vertical plane. The two side wall plates have an upper wall plate at the top and a lower wall plate at the bottom. The side wall plates are provided with a third connecting hole for connecting with the adjacent single-sided side mold and / or adjusting clamp, for example, by bolt connection. The concave angle side mold 322 includes an inner template arranged at right angles in a vertical plane and upper wall plates, lower wall plates, and side wall plates located around the inner template. It does not have through-rib notches on the upper and lower wall plates. Except for the setting position, its function and connection method with the surrounding side molds and / or adjusting clamps are similar to those of the single-sided side mold 31, and will not be described in detail here. Example

[0061] Based on Embodiment 1, this embodiment further proposes a molding method for a prefabricated shear wall molding die based on the above-mentioned modular assembly, which specifically includes the following steps:

[0062] S1, such as Figure 6 As shown, long strip modules 2 are arranged on the bottom formwork platform 1 according to the shape of the shear wall. One end of the shear wall is equipped with a support leg. The specific structure is as described in the prior patent text provided in the background art, and will not be repeated here.

[0063] Specifically, the lower elongated steel plate 21, the lower right-angled steel plate 22, and the lower support leg steel plate 23, which are manufactured in sections, are combined to form the lower elongated module 2. The lower positioning hole 24 on the lower elongated module 2 has special requirements for its position, and it must at least avoid the position where the shear wall reinforcement passes through, as shown in the figure.

[0064] S2, such as Figure 7 As shown, a steel mesh for binding the lower layer of steel bars 61 of the shear wall is tied to the lower long strip module 2;

[0065] S3, such as Figure 9 As shown, the side assembly module 3 is assembled on the lower long strip module 2, so that the lower layer steel bar 61 of the wall passes through the lower through bar notch 318 of the single side module 31. At the same time, the single side module 31 and the corner side module 32 are connected in sequence with bolts along the circumference of the shear wall.

[0066] Since the upper and lower reinforcing bar openings are arranged opposite each other on the inner formwork, the precise positioning of the wall reinforcement is achieved after the position of the lower reinforcing bar 61 in each lower reinforcing bar opening 318 is determined. This precise positioning includes not only the horizontal positioning of the lower reinforcing bar mesh, but also the determination of the positional relationship between the upper reinforcing bar 62 and the lower reinforcing bar 61 in the vertical and horizontal directions.

[0067] S4, such as Figure 8 and Figure 10 As shown, the upper layer of steel mesh of the shear wall is tied so that the upper layer of steel bars 62 of the wall passes through the upper through bar notch 317 of the single side formwork 31.

[0068] S5. Assemble the long strip module 5 on top of the side assembly module 3 to complete the assembly of the main body of the mold;

[0069] S6. Concrete for pouring shear walls;

[0070] S7. Remove the formwork when the concrete strength meets the requirements for demolding. The demolding sequence is from top to bottom: first remove the upper long strip formwork 5, then remove the side assembly formwork 3, and finally remove the lower long strip formwork 2. Clean the formwork for future reuse.

[0071] In this embodiment, the molding die can be made of steel, aluminum, or plastic.

[0072] In this embodiment, various standard-sized single-sided side molds 31 and corresponding corner side molds 32 can be combined to form a side assembly module 3, aligning the dimensions of the side assembly module 3 with the lower elongated module 2 to accommodate the current shear wall reinforcement spacing requirements and / or shear wall size requirements. Furthermore, adjusting clips can be added between the sidewalls of adjacent single-sided side molds 31 and / or between adjacent single-sided side molds 31 and corner side molds 32 as needed to further accommodate changes in component dimensions.

[0073] In summary, in the above embodiments, the side molds of the shear wall mold are designed as modular, unitized, and splicable structures. Each single-sided side mold, as an independent unit, is provided with a through-beam notch for the shear wall reinforcement to pass through. Since each single-sided side mold can be individually disassembled from the side assembly module 3, it can prevent local reinforcement jamming and make the overall demolding of the precast components easier. Furthermore, through-beaming via the through-beam notch is simpler to operate and more efficient in shear wall reinforcement arrangement than through-beaming via holes, and it can reduce the use of sealing components. In addition, the single-sided side molds, as independent units, can be manufactured according to standardized dimensions, which can expand the applicability of the mold and increase the turnover rate of the mold.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
