Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a streamlined wall formwork system and its construction method. Background Technology

[0002] With social development and advancements in construction technology, buildings are increasingly emphasizing aesthetics, resulting in a growing number of buildings with diverse shapes. However, the construction of irregularly shaped concrete structures presents a significant challenge, particularly in formwork support. Traditional formwork systems operate on a level plane, allowing tie rods to be easily connected using a joist system. In contrast, irregularly shaped structures, especially streamlined designs with multiple curved connections, are prone to misalignment at formwork joints. Furthermore, the curved shape causes the tie rods to be off-plane, making it difficult to effectively secure the entire formwork system. This significantly increases the risk of formwork bursting during pouring.

[0003] To address the formwork support problem for irregularly shaped walls, some researchers have proposed formwork structures specifically for such walls. For example, utility model patent application number CN201820547882.7 discloses a formwork structure for an irregularly shaped concrete wall, comprising an inner formwork, vertical ribs, and horizontal ribs. The inner formwork is a wall-shaped template, and its internal cavity dimensions correspond to the outer dimensions of the irregularly shaped wall, including a cuboid portion and a cylindrical portion. The horizontal ribs include end face ribs and side face ribs. The inner wall of the end face ribs is curved, and the inner wall of the side face ribs has one curved end and the other horizontal end. The end face ribs and side face ribs are fixedly connected by bolts. The internal cavity dimensions formed by the end face ribs and the two side face ribs correspond to the dimensions of the inner formwork. Vertical ribs are evenly distributed between the inner formwork and the horizontal ribs. The formwork is fixedly connected by tie bolts. This technical solution can effectively fix the formwork and is suitable for use when casting irregularly shaped walls with added columns on shear walls.

[0004] However, the aforementioned patents rely on transverse ribs on the sides and ends to fix the entire formwork system, lacking lateral support, making it prone to bursting or collapse during concrete pouring. Furthermore, the formwork structure provided by the aforementioned patents is not suitable for streamlined walls. Therefore, the applicant proposes a streamlined wall formwork system and its construction method, suitable for the support and pouring of streamlined walls. This system boasts advantages such as structural stability and strong integrity, effectively resisting the outward tension generated during concrete pouring and minimizing the risk of bursting during pouring. Summary of the Invention

[0005] The purpose of this invention is to provide a streamlined wall formwork system and its construction method, which has the advantages of structural stability and strong integrity, and can effectively resist the outward tension generated during concrete pouring, making it less prone to the problem of formwork bursting during pouring.

[0006] To achieve the above objectives, according to one aspect of the present invention, a streamlined wall formwork system is provided, comprising a plurality of tie rods, and further comprising:

[0007] Multiple template components are connected sequentially to form a streamlined template, and the joints between adjacent template components are equipped with locking structures to secure the connection between the templates.

[0008] A support frame is provided, in which the streamlined template is located. The streamlined template is fixedly connected to the support frame by a plurality of tie rods and nuts. The tie rods pass through the streamlined template and the support frame and are firmly fixed to the support frame and the streamlined template by nuts.

[0009] A diagonal brace assembly is provided on the outer side of the support frame. The diagonal brace assembly includes a diagonal brace and a fixing member. The upper end of the diagonal brace is connected to the support frame, and the lower end is connected to the fixing member.

[0010] Furthermore, the template assembly includes a large template, a small template, and a sleeve through which the tie rod can pass. Both the large and small templates are semi-circular in shape, with the inner diameter of the large template being larger than the outer diameter of the small template. The large and small templates share a common central axis, have the same opening direction, and are aligned at both ends. The outer end of the middle of the large template is connected to and tangent to the support frame. The sleeve is supported between the large and small templates along the radial direction of the large and small templates. Tie holes for the tie rod to pass through are provided on the large and small templates at the positions where they connect with the sleeve.

[0011] Furthermore, the two ends of the sleeve are respectively provided with structures that fit the concave surface of the large template and the convex surface of the small template, so that the two ends of the sleeve are tightly fitted to the concave surface of the large template and the convex surface of the small template.

The locking structure includes a connector, a plug-in block, and a wedge. The connector is located at the end of the concave surface of the small template, and the plug-in block is located at the end of the convex surface of the large template. The connector has a plug rod portion with a wedge groove, and the plug-in block has a plug hole. When the ends of the large and small templates of two adjacent template components are aligned and connected, the plug rod portion of each connector is inserted into the plug hole of the corresponding end plug-in block, and the wedge groove passes through the plug-in block. The wedge is inserted into the wedge groove to lock the aligned and connected templates.

[0013] Furthermore, the tie rod, through a nut-fixed support frame and streamlined template fixing structure, includes a three-point fixing structure and a four-point fixing structure. In the three-point fixing structure, the tie rod is perpendicular to the support frame and passes through the middle of the large and small templates of the template assembly. The three-point fixing structure includes three nuts, three washers, and a screw platform. The screw platform is located on the concave surface in the middle of the small template. One side of the screw platform is an arc-shaped surface that matches the concave surface of the small template, and the other side is a flat surface. The three nuts and three washers are respectively installed at three points, the first point and the third... The four-point fixing structure has four tie rods, each located on the outer side of the support frame on both sides of the streamlined template's extension direction. The first point is the outer side of the support frame connected to the large template, and the second point is the plane of the screw platform. Compared to the tie rod of the three-point fixing structure, the tie rod of the four-point fixing structure is deflected by 40-50 degrees in the horizontal plane and penetrates the large and small templates in the radial direction. Four nuts and four washers are installed at the four points. The first and fourth points are located on the outer side of the support frame on both sides of the streamlined template's extension direction, and the second and third points are located on the outer convex surface of the large template and the inner concave surface of the small template, respectively.

[0014] Furthermore, the support frame includes a horizontally arranged transverse frame, a vertically arranged longitudinal frame, and a buckle plate. The transverse frame includes multiple transverse rods arranged sequentially along the vertical direction. The buckle plate is provided with a transverse groove through which the transverse rods pass and a through hole for the tie rods to pass through. The longitudinal frame is also provided with a transverse groove through which the transverse rods pass. The upper end of the diagonal brace is connected to the longitudinal frame.

[0015] Furthermore, the diagonal brace includes an upper screw, a lower screw, and a steel pipe located between the upper and lower screws. The threads of the lower and upper screws are opposite in direction. The upper inner wall of the steel pipe is provided with an internal thread structure adapted to the upper screw, and the lower inner wall of the steel pipe is provided with an internal thread structure adapted to the lower screw. The fixing component includes a grooved embedded part, a connecting block, and a rubber gasket. The upper end of the grooved embedded part is open, and the longitudinal cross-sectional shape of its inner groove is an inverted T-shape. The connecting block is disposed in the grooved embedded part, and the connecting block has a T-shaped part that matches the inner groove of the grooved embedded part. The rubber gasket is disposed between the lower end of the connecting block and the grooved embedded part. The upper end of the connecting block is provided with two connecting holes. Two diagonal braces are connected to each connecting block. The lower ends of the lower screws of the two diagonal braces are respectively hinged to the two connecting holes of the connecting block, and the upper ends of the upper screws of the two diagonal braces are respectively hinged to the support frame.

[0016] Furthermore, the streamlined template also includes a 270° annular template assembly. This assembly comprises two 270° annular templates, one large and one small, multiple sleeves positioned between the two templates, multiple tie rods passing through the sleeves and extending through the templates, and nuts and washers on the tie rods. The two 270° annular templates share a common central axis, have the same opening direction, and their ends are aligned. The 270° annular template assembly connects two streamlined templates with perpendicular extension directions. The end of the larger 270° annular template is connected to the end of the smaller template in the template assembly, and the end of the smaller 270° annular template is connected to the end of the larger template in the template assembly. A locking structure is provided at the joint between the 270° annular template assembly and adjacent template assemblies to secure the connection between the templates.

[0017] Furthermore, the support frame has an inside corner and an outside corner at the 270° annular template group. An inside corner buckle and an outside corner buckle are respectively provided at the inside corner and outside corner. The inside corner buckle is L-shaped, including a first plate portion and a second plate portion that are perpendicular to each other. Both the first plate portion and the second plate portion have insertion holes. The support frame has a connecting rod that can pass through the insertion holes in the first plate portion and the second plate portion. The connecting rod has a wedge groove, in which a wedge is installed to connect and fix the inside corner buckle and the support frame. The outside corner buckle includes a first half-outside corner buckle and a second half-outside corner buckle. The first half-outside corner buckle and the second half-outside corner buckle are obtained by vertically splitting the outside corner buckle in half at the corner. The inner walls of the first half-outside corner buckle and the second half-outside corner buckle have groove structures adapted to the support frame. Both the first half-outside corner buckle and the second half-outside corner buckle have through holes for the pull rod to pass through. The first half-outside corner buckle and the second half-outside corner buckle are fixed to the support frame by the pull rod and the nut.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0046] Example 1

[0047] This embodiment provides a streamlined wall formwork system, such as Figure 1 As shown, the system includes a support frame, multiple template components, a 270° annular template group, multiple diagonal brace components, and multiple tie rods 1. The template components are connected sequentially to form a streamlined template. Two streamlined template sections with perpendicular extension directions are connected by the 270° annular template group, forming an L-shaped streamlined template. Locking structures are provided at the joints of adjacent template components and at the joints between template components and the 270° annular template group to secure the connections between the templates. The L-shaped streamlined template is located within the support frame, which is also L-shaped overall.

[0048] Figure 1 , such as 2, Figure 3 and Figure 4 As shown, the support frame includes a horizontally arranged transverse frame 8, a vertically arranged longitudinal frame 9, and a buckle plate 10. The transverse frame 8 includes multiple transverse rods arranged sequentially along the vertical direction. The buckle plate 10 is provided with transverse grooves 11 for the transverse rods to pass through and through holes 12 for the tie rods 1 to pass through. Multiple buckle plates 10 are arranged along the length of the support frame. The longitudinal frame 9 is also provided with transverse grooves 11 for the transverse rods to pass through. The upper end of the diagonal brace 4 is connected to the longitudinal frame 9.

[0049] like Figure 1 , Figure 5 , Figure 6 and Figure 10 As shown, the support frame has an inside corner and an outside corner at the 270° annular template group, and an inside corner buckle 13 and an outside corner buckle 14 are respectively provided at the inside corner and the outside corner. The inside corner buckle 13 is L-shaped and includes a first plate part and a second plate part that are perpendicular to each other. The first plate part and the second plate part are integral. Both the first plate part and the second plate part are provided with a socket structure. The support frame is provided with a plug rod 17 that can pass through the socket structure of the first plate part and the second plate part. The plug rod 17 is provided with a wedge groove. A wedge 15 is installed in the wedge groove to connect and fix the inside corner buckle 13 and the support frame. The corner buckle 14 includes a first half corner buckle and a second half corner buckle. The first half corner buckle and the second half corner buckle are obtained by vertically splitting the corner buckle 14 at the corner. The first half corner buckle and the second half corner buckle are two independent parts. The inner walls of the first half corner buckle and the second half corner buckle are provided with groove structures 1401 that are adapted to the horizontal frame 8 and the vertical frame 9. Both the first half corner buckle and the second half corner buckle are provided with through holes 1402 for the pull screw 1 to pass through. The first half corner buckle and the second half corner buckle are fixed at the corner position of the support frame by the pull screw 1 and the nut.

[0050] like Figure 1and Figure 2 As shown, the template assembly includes a large template, a small template, and a sleeve 2 through which tie rods 1 can pass. Both the large and small templates are semi-circular in shape, with the inner diameter of the large template being larger than the outer diameter of the small template. The large and small templates share a central axis, have the same opening direction, and their ends are aligned. The outer end of the middle of the large template is connected and tangential to the buckle plate 10 fastened to the transverse frame 8. The sleeve 2 is supported between the large and small templates along the radial direction, and can be used to maintain the distance between the large and small templates, i.e., the thickness of the streamlined wall 16. Both ends of the sleeve 2 are respectively provided with structures that fit the concave surface of the large template and the convex surface of the small template, so that both ends of the sleeve 2 are tightly fitted to the concave surface of the large template and the convex surface of the small template, thus preventing concrete from entering the sleeve 2 during concrete pouring. The large and small templates are provided with tie holes at the positions where they connect with the sleeve 2, through which the tie rod 1 passes. The tie rod 1 passes through the tie holes on the large and small templates and the sleeve 2. After construction is completed, the tie rod 1 can be pulled out from the sleeve 2, so that the tie rod 1 can be reused multiple times, which can effectively save costs.

[0051] like Figure 1 As shown, the 270° annular template assembly includes two 270° annular templates, one large and one small, three sleeves 2 positioned between the two 270° annular templates, multiple tie rods 1 passing through the sleeves 2 and through the two 270° annular templates, and nuts and washers mounted on the tie rods 1. The two 270° annular templates share a common central axis, have the same opening direction, and their ends are aligned. The 270° annular template assembly is used to connect two streamlined templates with perpendicular extension directions. The end of the larger 270° annular template is connected to the end of the smaller template in the template assembly, and the end of the smaller 270° annular template is connected to the end of the larger template in the template assembly. A locking structure for securing the connection between the templates is also provided at the joint between the 270° annular template assembly and adjacent template assemblies.

[0052] like Figure 1 , Figure 7 and Figure 10As shown, when adjacent template components are connected, the ends of the large and small templates of one template component are sequentially connected to the ends of the small and large templates of another template component, respectively. When the 270° annular template group is connected to the template component, the end of the larger 270° annular template is connected to the end of the small template, and the end of the smaller 270° annular template is connected to the end of the large template. The locking structure includes a connector 6, a plug block 7, and a wedge 15. The connector 6 is located at the end of the concave surface of the small template and the smaller 270° annular template, and the plug block 7 is located at the end of the convex surface of the large template and the larger 270° annular template. The connector 6 has a insertion rod portion 601 with a wedge groove. The insertion block 7 has an insertion hole. When the ends of the large and small templates of two adjacent template assemblies are aligned and connected, or when the ends of the 270° annular templates of the 270° annular template group are aligned and connected with the ends of the large and small templates of the template assembly, the insertion rod portion 601 of each end connector 6 is inserted into the insertion hole of the corresponding end insertion block 7, and the wedge groove passes through the insertion block 7. Installing wedges 15 in each wedge groove locks the aligned templates together. The locking structure effectively ensures the alignment of the ends of each template, guarantees the stability of the streamlined template structure, and, together with the sleeve 2, maintains the distance between the large and small templates, resulting in a streamlined wall 16 with uniform thickness and an aesthetically pleasing shape.

[0053] like Figure 1 , Figure 2 and Figure 3As shown, the streamlined template is fixedly connected to the support frame via multiple tie rods 1 and nuts. The tie rods 1 pass through the streamlined template and the support frame, and are firmly fixed to the support frame and the streamlined template via nuts. The fixing structure of the tie rods 1 and the support frame and streamlined template via nuts includes a three-point fixing structure and a four-point fixing structure. In the three-point fixing structure, the tie rods 1 are perpendicular to the buckle plate 10 fastened on the transverse frame 8, and pass through the large template and small template along the middle position of the template assembly. The three-point fixing structure includes three nuts, three washers, and a screw platform 3. The screw platform 3 is located at the concave surface in the middle position of the small template. One side of the screw platform 3 is an arc-shaped surface that fits with the concave surface of the small template, and the other side is a flat surface, which facilitates installation and tightening of nuts. Three nuts and three washers are installed at three points. The first and third points are located on the outer surfaces of the support frames on both sides of the streamlined template's extension direction, specifically on the outer surfaces of the corresponding fasteners 10 fastened to the transverse frame 8. The first point is on the outer surface of the fastener 10 connected to the large template, and the second point is on the plane of the screw platform 3. Compared to the three-point fixed structure, the four-point fixed tie rod 1 is deflected 40-50 degrees, preferably 45 degrees, in the horizontal direction and penetrates the large and small templates radially. The tie rods 1 of each four-point fixed structure are at different heights to avoid mutual obstruction. Furthermore, the heights of the tie rods 1 that would cause mutual obstruction should all be different. Four nuts and four washers are installed at four points. The first and fourth points are located on the outer surfaces of the fasteners 10 fastened to the transverse frame 8 on both sides of the streamlined template's extension direction, and the second and third points are located on the outer convex surface of the large template and the inner concave surface of the small template, respectively. By using a three-point fixing structure and a four-point fixing structure, the structural stability of the streamlined template can be effectively guaranteed, and the connection between the streamlined template and the support frame can be stabilized, further reinforcing the structure of the streamlined template.

[0054] like Figure 1 , Figure 8 and Figure 9As shown, the diagonal brace assembly includes a diagonal brace 4 and a fixing component 5. The fixing component 5 includes a grooved embedded part 501, a connecting block 502, and a rubber gasket 503. The upper end of the grooved embedded part 501 is open, and the longitudinal cross-sectional shape of its inner groove is an inverted T-shape. The connecting block 502 is disposed in the grooved embedded part 501, and the connecting block 502 has a T-shaped part that matches the inner groove of the grooved embedded part 501. The rubber gasket 503 is disposed between the lower end of the connecting block 502 and the grooved embedded part 501. The upper end of the connecting block 502 is provided with two connecting holes. The diagonal brace 4 includes an upper screw, a lower screw, and a steel pipe located between the upper screw and the lower screw. The threads of the lower screw and the upper screw have opposite directions. The upper inner wall of the steel pipe is provided with an internal thread structure adapted to the upper screw, and the lower inner wall of the steel pipe is provided with an internal thread structure adapted to the lower screw. The length of the diagonal brace 4 can be adjusted by rotating the steel pipe. Each connecting block 502 is connected to two diagonal braces 4. The lower ends of the lower screws of the two diagonal braces 4 are respectively hinged to the two connecting holes of the connecting block 502, and the upper ends of the upper screws of the two diagonal braces 4 are respectively hinged to the longitudinal frame 9 of the support frame. The diagonal brace assembly is used to support and reinforce the support frame, and also to support the streamlined formwork. It can help the streamlined formwork resist the outward tension generated during concrete pouring, and is less likely to cause the problem of formwork bursting during pouring.

[0055] The working principle of this invention: This invention uses multiple template components connected sequentially to form a streamlined template for casting a streamlined wall 16. The interlocking structure and sleeve 2 improve the stability of the streamlined template structure, maintaining the distance between the templates and resulting in a streamlined wall 16 with uniform thickness and an aesthetically pleasing shape. By setting up a support frame and using tie rods 1 and nuts to connect and fix the streamlined template and the support frame, not only is the structural stability of the streamlined template further guaranteed, but the connection between the streamlined template and the support frame is also stabilized, further reinforcing the structure of the streamlined template. The diagonal brace components support and reinforce the support frame, which in turn supports the streamlined template, helping it resist the outward tension generated during concrete pouring and reducing the risk of formwork bursting during pouring.

[0056] In summary, the streamlined wall formwork system provided by this invention has the advantages of structural stability and strong integrity. It can effectively resist the outward tension generated during concrete pouring, and is less prone to the problem of pouring burst. Moreover, the poured streamlined wall 16 has uniform thickness and beautiful shape.
