Description

Technical Field

[0001] The utility model relates to the technical field of wall decoration, in particular to a wall concrete finishing formwork. Background Technique

[0002] With the increasing demand for lightweight decoration of concrete structure walls in the construction industry, the method of synchronously fixing the wall finishing shape during concrete pouring not only significantly shortens the construction period and reduces costs, but also is favored because of its strong adaptability and ability to meet diverse engineering requirements. This construction method realizes the one-time forming of the finishing shape, but to ensure the integrity and aesthetics of the concrete finished product, it also puts forward higher requirements for the formwork removal process. Therefore, in-depth research on the finishing formwork, including the development of innovative formwork that is easy to install and remove, is of great significance for promoting the development of building construction towards a more efficient and environmentally friendly direction.

[0003] CN211923512U discloses a cast-in-place decorative concrete structure based on a WISA formwork system, including an inner formwork structure and an outer formwork structure that are abutted against both sides of the concrete and tied with tie rods. The inner formwork structure / outer formwork structure includes a curved section and a straight section. The formwork located in the curved section is cut with grooves on the side facing away from the concrete. The bent small cross ribs and the fixing strips are fixed to the grooved formwork with nails and are integrally in a curved body. The secondary vertical ribs are vertically arranged at intervals on the side of the formwork away from the concrete, and the large cross ribs are horizontally arranged at intervals outside the secondary vertical ribs. The formwork located in the straight section is vertically provided with a plurality of secondary vertical ribs at intervals on the side facing away from the concrete, and the horizontal back ribs are horizontally arranged at intervals outside the secondary vertical ribs.

[0004] This patent provides a formwork system with a smooth surface and good hydrophobicity, ensuring that the surface of the concrete after pouring is smooth without a rough surface. At the same time, the formwork joint treatment is tight, avoiding misalignment, and the arc chamfer transitions smoothly and evenly. The curved formwork of its formwork system is processed by on-site machine tool grooving, with a short processing cycle, low cost, and high stiffness and reuse rate. However, this technical solution does not clarify the connection method of the detailed structure of the formwork, which is not conducive to the feasibility and safety of construction. In addition, this technical solution does not involve a formwork removal device corresponding to the installation of the formwork, which will affect the construction efficiency and the protection of the concrete finished product.

[0005] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, although the applicant studied a large number of documents and patents when making this utility model, due to space limitations, not all details and contents are listed in detail. However, this does not mean that this utility model does not possess the features of these prior arts. On the contrary, this utility model already possesses all the features of the prior arts, and the applicant reserves the right to add relevant prior arts in the background technique. Content of the Utility Model

[0006] In view of the deficiencies of the prior art, the present application proposes a wall concrete finishing formwork, especially a concrete finishing formwork that is easy to install and disassemble, aiming to solve one or more technical problems in the prior art.

[0007] In the prior art, although the installation of the finishing formwork has achieved an efficient construction method that is synchronized with concrete pouring and allows for the one-time forming of the wall finishing shape, the existing defects mainly include: the lack of devices for precise positioning and adjustment of the formwork during installation, resulting in difficulties in ensuring the stability of the formwork and the accuracy after concrete pouring; the connection between the formwork and the concrete is not firm enough, affecting the stability of the overall structure; in addition, the installation of the formwork does not fully consider the special requirements of different finishing shapes for the formwork structure, restricting the diversity and complexity of the finishing design.

[0008] Therefore, the present utility model proposes a wall concrete finishing formwork for the above technical problems. It includes a formwork frame panel and a finishing shape panel. When combining the finishing shape panel and the formwork frame panel, the formwork frame panel is detachably connected to the finishing shape panel by means of screws passing through a number of bolt connection holes arranged at intervals on the finishing shape panel. When removing the formwork frame panel and the finishing shape panel from the wall surface, a number of jack assemblies are detachably installed on the formwork frame panel. Among them, on the removed side of the formwork frame panel, the jack assembly contacts the concrete wall surface; on the non-removed side of the formwork frame panel, the jack assembly contacts the adjacent formwork frame panel.

[0009] By adopting a detachably connected formwork frame panel and a finishing shape panel, the present utility model greatly reduces the time and cost required for traditional decoration finishes and speeds up the construction progress. The precise fit between the finishing shape panel and the formwork frame panel ensures the smoothness and flatness of the wall surface after concrete pouring, avoiding defects such as surface inequality commonly found in traditional construction methods. In addition, the formwork frame panel is fixed to the finishing shape panel by bolts, providing sufficient stiffness to resist the pressure generated during concrete pouring and effectively controlling the deformation of the formwork. The setting of the jack assembly allows the formwork frame panel to be pushed out parallelly, avoiding damage to the concrete wall surface and ensuring the smoothness and safety of the removal process.

[0010] According to a preferred embodiment, the template frame panel is configured with a panel surface that abuts against the decorative molding panel, and a composite structure including a plurality of vertical channel steels and a plurality of transverse channel steels is configured on a side of the panel surface away from the decorative molding panel, wherein the vertical channel steels are arranged along the height direction of the panel surface, and the transverse channel steels are arranged along the width direction of the panel surface, so as to form a cross-grid frame structure in space. By configuring the composite structure composed of vertical channel steels and transverse channel steels on the template frame panel, a cross-grid frame can be formed in space, which significantly improves the overall stability and rigidity of the template system. The grid-like frame structure effectively disperses the lateral pressure generated during the pouring and curing of concrete, reduces the local pressure concentration on the template, and thus protects the integrity of the concrete wall surface. In addition, the arrangement of the vertical and transverse channel steels increases the bearing area of ​​the template frame panel, so that the template can withstand a larger load, the supporting effect is more uniform, the flatness of the concrete wall surface during the pouring process is ensured, and the unevenness of the wall surface caused by the deformation of the template is avoided, which is suitable for a wider range of construction conditions.

[0011] According to a preferred embodiment, a plurality of transverse channel steels are arranged in pairs at different heights of the template frame panel, and the webs of the two transverse channel steels in the same group are arranged opposite to each other, and the flanges are separated from each other. The layout of the webs of the transverse channel steels being arranged opposite to each other and the flanges being separated from each other increases the local rigidity of the template frame panel, more evenly distributes the lateral pressure generated during concrete pouring, reduces the local stress concentration on the template, and provides a more solid working platform for concrete pouring.

[0012] According to a preferred embodiment, the edge of the formwork frame panel is pre-configured with a plurality of assembly holes, so that when a concrete wall needs to be configured with multiple formwork frame panels, different formwork frame panels can be detachably connected through assembly bolts arranged on the assembly holes. The pre-set assembly holes and assembly bolts make the installation and removal process of the formwork frame panel faster, reduce the need for on-site drilling and temporary fixation, and thus speed up the construction progress. In addition, by connecting multiple formwork frame panels into a whole through assembly bolts, the overall rigidity and bearing capacity of the formwork structure are enhanced, and the lateral pressure generated during concrete pouring is effectively resisted.

[0013] According to a preferred embodiment, the jack assembly balances the jacking force by arranging a set of jack assemblies at the top and bottom of the formwork frame panel to be demolished respectively, and multiple jack assemblies in the same set are kept at the same horizontal height. Arranging a set of jack assemblies at the top and bottom respectively ensures that the jacking force is balanced in the vertical direction during the demolition of the formwork frame panel, reduces the local pressure on the newly poured concrete wall surface, effectively prevents wall surface cracks or damages, and protects the integrity and durability of the concrete wall surface. In addition, different jack assemblies in the same set being at the same horizontal height helps to ensure the synchronous operation of the jack assemblies during the entire demolition process, reduces the safety risks caused by improper operation, and also improves the efficiency of the demolition operation.

[0014] According to a preferred embodiment, the jack assembly includes a jack barrel and an insert piece that are connected to each other. Among them, the insert piece of the jack assembly located on the demolished side of the formwork frame panel is directly connected to the jack barrel, and the insert piece of the jack assembly located on the non-demolished side of the formwork frame panel is indirectly connected to the jack barrel through a steel plate. The design of the jack assembly allows corresponding installation strategies to be adopted according to the different structural characteristics on both sides. This differential configuration method ensures the uniformity and stability of the jacking force during the demolition process, thereby improving the construction safety and efficiency.

[0015] According to a preferred embodiment, the insert piece is inserted into the gap formed between the webs of two transverse channel steels in the same set to achieve a detachable connection between the jack assembly and the formwork frame panel. The design of the insert piece allows for quick disassembly and assembly between the jack assembly and the formwork frame panel, simplifies the demolition process, and improves the construction efficiency. The inserted connection of the insert piece provides a stable fixing point for the jack assembly, ensuring that the jack assembly will not displace relative to the formwork frame panel during the jacking process. In addition, the gap between the webs of the transverse channel steels provides enough space for the insert piece, enabling the jack assembly to be flexibly adjusted between transverse channel steels at different positions as needed.

[0016] According to a preferred embodiment, the jack assembly includes a hydraulic cylinder and hydraulic pipelines. Multiple jack barrels in the same set are respectively connected to the same hydraulic cylinder through the hydraulic pipelines. Connecting different jack barrels in the same set to the same hydraulic cylinder through the hydraulic pipelines ensures that each jack barrel can be jacked synchronously, providing a uniform and balanced jacking force.

[0017] According to a preferred embodiment, a countersunk portion of the screw is provided with a first gasket, and the first gasket prevents concrete leakage by filling the gap between the screw and the decorative molding panel. By tightly filling the gap between the screw and the decorative molding panel, the first gasket effectively prevents concrete leakage during the concrete pouring process, ensuring the integrity and aesthetics of the concrete wall surface. It also helps to maintain the uniformity and smoothness of the concrete wall surface, avoiding wall surface defects caused by leakage and improving the overall quality of the construction.

[0018] According to a preferred embodiment, the portion of the screw passing through the formwork frame panel is threadedly connected to a nut, and a second gasket for enhancing the fixing effect is provided between the nut and the panel surface. As a buffer between the nut and the panel surface, the second gasket effectively disperses the fastening force, reduces the direct pressure of the nut on the panel surface, and prevents deformation or damage of the panel surface.

DETAILED DESCRIPTION

[0028] The utility model is described in detail below in conjunction with the accompanying drawings.

[0029] The utility model relates to a wall concrete facing template, such as Figure 1 As shown, it comprises: a facing molding panel 200 for contacting with the poured concrete to determine the shape of the concrete after hardening, and a template frame panel 100 for resisting the concrete pressure to reduce the deformation of the facing molding template. The template frame panel 100 and the facing molding panel 200 can be detachably combined with the help of a connection assembly before pouring concrete, and after the concrete is hardened, the two can be removed from the concrete wall as a whole with the help of a jack assembly 300.

[0030] Preferably, if Figure 1 , Figure 4 As shown, the template frame panel 100 includes a plate surface 110, a vertical channel steel 120 and a transverse channel steel 130. The plate surface 110 can be against the decorative molding panel 200. The material thereof can be selected from high-strength steel materials with high corrosion resistance and durability such as Q325. The thickness thereof can be set to 6mm, 8mm, 10mm, etc. The specific value can be calculated and determined according to factors such as casting pressure and template size. The side of the plate surface 110 away from the decorative molding panel 200 is configured as a composite structure, which includes a plurality of vertical channel steels 120 and a plurality of transverse channel steels 130. The vertical channel steels 120 (commonly referred to as vertical ribs) are arranged equidistantly along the height direction of the plate surface 110 to provide vertical support; and the transverse channel steels 130 (commonly referred to as horizontal ribs) are arranged equidistantly along the width direction of the plate surface 110 to provide horizontal tension. Through this arrangement, the vertical channel steels 120 and the transverse channel steels 130 form a cross-grid structure in space, thereby enhancing the stability and bending resistance of the entire template frame panel 100. Figure 1 As shown, a plurality of transverse channel steels 130 are arranged in pairs at different heights of the template frame panel 100, and each group includes two transverse channel steels 130 with webs arranged opposite to each other and flanges facing away from each other. The spacing between adjacent vertical channel steels 120 is preferably set to 250-300 mm, and the spacing between two adjacent groups of transverse channel steels 130 is preferably set to 600-800 mm.

[0031] Preferably, the material of the decorative styling panel 200 is selected according to design requirements and engineering environment. Commonly used materials include but are not limited to wood, MDF board, GRC (glass fiber reinforced cement), FRP (glass fiber reinforced plastic), etc., to meet different strength, weight, and durability requirements. To ensure the lightness and ease of installation of the decorative styling panel 200, its maximum thickness is controlled within 2 cm, which helps to reduce the weight of the entire formwork while not affecting its structural stability and load-bearing capacity. The decorative styling panel 200 is manufactured using advanced mechanical manufacturing techniques, such as CNC (computer numerical control) machine tool processing, to ensure accuracy and production efficiency. In addition, laser electronic printing technology is also used to achieve complex textures and patterns, providing higher design flexibility.

[0032] Preferably, as Figure 5 shown, the connection components for connecting the decorative styling panel 200 and the formwork frame panel 100 include a screw 140 and a nut 150. As Figure 1 , Figure 2 shown, bolt connection holes 210 are accurately configured and aligned on the panel surface 110 of the formwork frame panel 100 and the decorative styling panel 200. The screw 140 can pass through the bolt connection holes 210 of the decorative styling panel 200, then penetrate the corresponding holes on the formwork frame panel 100, and finally be threadedly fastened to the nut 150 on the side away from the panel surface 110 of the decorative styling panel 200, thus achieving a firm connection between the decorative styling panel 200 and the formwork frame panel 100. To ensure the uniform stress and structural stability of the entire formwork, the spacing between adjacent bolt connection holes 210 is preferably 600 mm × 600 mm. The spacing of the connection holes 600 mm × 600 mm is determined based on a certain modulus and construction convenience. If the formwork size is large or more dense connection points are required to improve stability, the spacing can be considered to be reduced, such as 500 mm × 500 mm or 450 mm × 450 mm. For smaller or lighter formworks, the spacing can be appropriately increased to reduce material usage, for example, 650 mm × 650 mm or 700 mm × 700 mm. In particular, when the wall decoration requirement is limited to a simple stripe effect, the decorative styling panel 200 can be simplified into several strip modules, which can be easily detachably connected to the formwork frame panel 100. This design reduces the setting of the back panel compared to the original decorative styling panel 200, not only reducing material usage but also simplifying the installation and disassembly processes and reducing the complexity of operations.

[0033] Preferably, the matching dimensions of the formwork frame panel 100 need to meet the design modulus. The width of each formwork frame panel 100 is preferably not more than 3m, and the height is preferably not more than 6m. When super-wide and super-high formwork is required for the concrete wall surface, it can be achieved by splicing and combining multiple formwork frame panels 100. Preferably, a number of assembly holes are pre-configured on the four edges of each formwork frame panel 100, so that when multiple formwork frame panels 100 need to be configured on the concrete wall surface, detachable connections can be realized between different formwork frame panels 100 through the assembly bolts arranged on the assembly holes. The assembly bolts between the formwork frame panels 100 are preferably not lower than M16 grade.

[0034] Preferably, as Figure 7 shown, the jacking component 300 balances the jacking force by arranging a set at the top and bottom of the formwork frame panel 100 to be demolished, and different jacking components 300 in the same group are kept at the same horizontal height. As a preferred implementation manner, two groups of jacking components 300 are provided in total, and two jacking components 300 are provided in each group. A total of four jacking components 300 are preferably symmetrically distributed at the four corners of the plate surface 110, so as to ensure the uniform distribution of the jacking force. In particular, when multiple formwork frame panels 100 are configured on the concrete wall surface, the jacking components 300 can be demolished one by one in sequence. Taking a formwork frame panel 100 to be demolished currently as an example, the formwork frame panel 100 on its adjacent side has been demolished, and this side is called the demolished side; the formwork frame panel 100 on its adjacent other side has not been demolished, and this side is called the non-demolished side.

[0035] Preferably, as Figure 6 shown, the jacking component groups in the same group have different installation methods on the demolished side and the non-demolished side of the formwork frame panel 100 to be demolished. Specifically, on the demolished side of the formwork frame panel 100, the jacking barrel 310 in the jacking component 300 contacts the concrete wall; on the non-demolished side of the formwork frame panel 100, the jacking barrel 310 in the jacking component 300 contacts the adjacent formwork frame panel 100. The jacking barrel 310 is a key part of the jacking component 300, which directly contacts the concrete wall or the adjacent formwork frame panel 100, and provides the jacking force through hydraulic or mechanical means to separate the formwork frame panel 100 from the concrete wall surface.

[0036] Preferably, as Figure 6As shown, the jack assembly 300 includes a insert piece 320 connected to the jack barrel 310. Among them, on the removed side of the formwork frame panel 100, the insert piece 320 of the jack assembly 300 is directly connected to the jack barrel 310; on the non-removed side of the formwork frame panel 100, the insert piece 320 of the jack assembly 300 is indirectly connected to the jack barrel 310 through a steel plate. The role of the steel plate is to connect the jack barrel 310 and the insert piece 320 that are not directly related in position, thereby ensuring the structural strength of their connection. The thickness of the steel plate is preferably the same as that of the insert piece 320, so that the steel plate and the insert piece 320 can be coplanar, ensuring structural stability. The thickness of the steel plate and the insert piece 320 can be selected as 40mm, for example.

[0037] Preferably, as Figure 6 shown, the insert piece 320 in the jack assembly 300 can be inserted into the gap formed between the webs of two transverse channel steels 130 in the same group, which enables a detachable connection between the jack assembly 300 and the formwork frame panel 100. The clearance fit between the insert piece 320 and the web of the transverse channel steel 130 has a high precision, ensuring a firm and easy-to-detach connection between the jack assembly 300 and the formwork frame panel 100. The insert piece 320 is provided with a plurality of through holes, and the transverse channel steel 130 is also equipped with hole positions matching these through holes. Simply align the through holes of the two and insert bolts to achieve a firm connection between the insert piece 320 and the transverse channel steel 130. In addition, the design of the insert piece 320 allows for quick insertion and extraction, greatly accelerating the installation and disassembly speed of the jack assembly 300 and improving construction efficiency.

[0038] Preferably, as Figure 7 shown, the jack assembly 300 can provide a jacking force hydraulically, and it includes a hydraulic cylinder 330 and a hydraulic pipeline 340 connecting each jack barrel 310. Two jack barrels 310 in the same group are connected to the same hydraulic cylinder 330 through the hydraulic pipeline 340, which realizes the synchronous output and precise control of the jacking force. The thrust of the hydraulic cylinder 330 is evenly distributed to each jack barrel 310 through the pipeline, ensuring that during the formwork removal process, the lifting speed and force of each barrel are consistent, avoiding damage to the concrete wall surface or formwork deformation caused by uneven jacking. In addition, a control valve for adjusting the jacking speed can be set on the hydraulic cylinder 330 to adapt to different construction conditions and requirements.

[0039] Preferably, as Figure 5As shown, the screw 140 can be an M8 cross countersunk screw 140, and a first gasket 160 is designed at the countersunk part. The function of the gasket is to form a sealing layer between the screw 140 and the decorative molding panel 200, thereby effectively filling the gap between the two. This design prevents the problem of slurry leakage during concrete pouring and ensures the integrity and uniformity of the concrete wall. The first gasket 160 is usually made of wear-resistant and corrosion-resistant materials such as rubber to adapt to the harsh environment during concrete pouring, while ensuring the durability and reusability of the gasket. The compressibility and elasticity of the first gasket 160 also help to absorb the slight displacement between the screw 140 and the panel, further improving the sealing performance of the connection.

[0040] Preferably, if Figure 5 As shown, the screw 140 passes through the portion of the template frame panel 100 and is threadedly connected to the nut 150, and a second gasket 220 is provided between the nut 150 and the plate surface 110 to enhance the fixing effect. The design of the second gasket 220 helps to disperse the local pressure generated when the nut 150 is tightened, avoids damage to the template frame panel 100, and also improves the stability and reliability of the connection. The material selection and thickness design of the second gasket 220 take into account the compatibility and long-term stability with the template frame panel 100, ensuring the durability and durability of the entire connection assembly during the construction process.

[0041] It should be noted that the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model.
