Description

Technical Field

[0001] The present invention belongs to the technical field of formwork, and particularly relates to a high-strength alloy formwork assembly and a construction method thereof. Background Art

[0002] During the pouring process of a building, it is usually necessary to use formwork to make a mold cavity before pouring concrete. There are also many technical documents about formwork in the prior art, mainly including angle-fixed formwork and angle-adjustable formwork. Since the angle of the angle-adjustable formwork can be adjusted, it has stronger adaptability.

[0003] For example, the patent with the application number 201010244348 discloses an angle-adjustable corner formwork, which includes two connecting arms. Each of the two connecting arms includes a connecting arm body, a hinge assembly formed at one end of the connecting arm body, and a splicing joint formed at the other end. Each of the two connecting arms has a working panel that participates in forming a mold cavity; when viewed from the cross-section, the first hinge assembly is a circular arc tongue formed at the hinge end of the first connecting arm body. The outer diameter side of one end of the circular arc tongue is adjacent to the part of the hinge end of the first connecting arm body close to the working panel, and the outer circumference of the circular arc tongue faces the working panel direction. The other end of the circular arc tongue is a free end; the second hinge assembly is a circular arc groove formed on the second connecting arm body for the free end of the circular arc tongue to insert and slide. This invention provides a corner formwork with a hinge structure that will not be washed open during the pouring process and is not easily disengaged during rotation. However, this structure can only be used as an external corner, and when the external corner angle is greater than 90°, due to the structural design of the circular arc tongue, an arc surface will be formed at the external corner instead of a sharp corner.

[0004] The patent with the application number 2018209375711 discloses an internal and external corner dual-purpose connecting formwork with adjustable angles, which includes flat formwork A, flat formwork B, adjustable connecting pieces and a shaped corner guard; both flat formwork A and flat formwork B are composed of a plate surface, perforated horizontal ribs and perforated vertical ribs. One side edge of flat formwork A and one side edge of flat formwork B are hinged together through a connecting shaft to form a symmetrical structure centered on the connecting shaft, and the working surfaces are located on the same side; on the non-working surface sides of flat formwork A and flat formwork B, there are multiple adjustable connecting pieces, and both ends of the adjustable connecting pieces are detachably and fixedly connected to flat formwork A and flat formwork B respectively; by rotating flat formwork A and flat formwork B around the connecting shaft, the included angle between the two can be adjusted between 5° and 355°, and after the angle adjustment is in place, it is locked and fixed through the adjustable connecting pieces; the smooth transition at the joint part of the workpiece surfaces is realized through the shaped corner guard. The structure is simple, flexible and convenient to use, has a high turnover rate, is beneficial to improving construction efficiency and reducing construction costs. Although this structure can be applied to external corners and internal corners, using the structural form of the connecting shaft, an arc surface is also formed at the external corners and internal corners instead of a sharp corner.

[0005] As in the prior art exemplified above, due to the structural characteristics of the rotating structure (whether it is rotation realized by a rotating shaft or the cooperation of an arc-shaped tongue and an arc-shaped groove), an arc-shaped surface will inevitably be formed at the corner, rather than a sharp angle.

[0006] Meanwhile, when pouring building components, the slurry and fine particles will more or less enter the rotating structure. During subsequent use, the rotating structure has to be cleaned. In severe cases, the rotating structure gets stuck and cannot be used continuously, resulting in a significant reduction in the service life of the angle-adjustable formwork. Summary of the Invention

[0007] In order to solve the problems that the existing angle-adjustable formwork will form an arc-shaped surface at the external and internal corners, and the slurry and fine particles during pouring will enter the rotating structure, resulting in a significant reduction in the service life, a high-strength alloy formwork assembly and its construction method are provided. On the premise that it can be used for pouring at the external and internal corners, a flat surface can be formed at both the external and internal corners, so as to form a flat external and internal corner. Moreover, during the use of the formwork assembly, the slurry or concrete during pouring will not enter the rotating structure, avoiding the problems of damage and jamming of the rotating structure due to foreign objects, and greatly improving the convenience and service life of use.

[0008] The above object is achieved by the following technical solutions:

[0009] A high-strength alloy formwork assembly includes two corner formworks and a rotating structure for driving the two corner formworks to rotate. An installation groove is provided on one side of the corner formwork, and a laying formwork is connected or used to be connected on the other side of the corner formwork.

[0012] In some embodiments, a first limiting groove is provided on the side of the first arc-shaped plate facing the second arc-shaped plate, a second limiting groove is provided on the side of the second arc-shaped plate facing the first arc-shaped plate, a limiting pin capable of sliding in the second limiting groove is provided at the end of the first arc-shaped plate far from the first arc-shaped arm, and a limiting pin capable of sliding in the first limiting groove is provided at the end of the second arc-shaped plate far from the second arc-shaped arm.

[0013] In some embodiments, a first retaining platform and a second retaining platform are respectively provided at both ends of the side of the first arc-shaped plate facing the second arc-shaped plate, a third retaining platform and a fourth retaining platform are respectively provided at both ends of the side of the second arc-shaped plate facing the first arc-shaped plate, and the first retaining platform, the second retaining platform, the third retaining platform and the fourth retaining platform interact with each other to jointly define the initial position and the sliding distance between the first arc-shaped plate and the second arc-shaped plate.

[0014] In some embodiments, the fourth retaining platform is located outside the first retaining platform, the second retaining platform is located outside the third retaining platform, and a third elastic member is provided between the first retaining platform and the third retaining platform.

[0015] In some embodiments, the elastic coefficient of the third elastic member is greater than the elastic coefficient of the first elastic member, and the elastic coefficient of the third elastic member is greater than the elastic coefficient of the second elastic member.

[0016] In some embodiments, gaskets are provided between the first arc arm, the second arc arm and the corner template, and the distance between the first arc arm and the second arc arm and the corner template is adjusted by setting the number of gaskets, and then the angle at which the corner template can rotate is adjusted by utilizing the rotating structure at different distances from the corner template.

[0017] In some embodiments, the end surfaces of the first curved plate and the second curved plate are provided with sealing covers for sealing the sliding groove.

[0018] In some embodiments, the tiling template includes a tiling board surface, one surface of the tiling board surface serves as the working surface of the template, a plurality of staggered horizontal beams and longitudinal beams are provided on the side of the tiling board surface away from the working surface, and the side of the tiling board surface away from the working surface is also covered with side edges, and a plurality of through holes are opened on the side edges.

[0019] In some embodiments, the side of the tiling plate facing away from the work surface is further separated by a number of reinforcing plates.

[0020] Based on the above high-strength alloy formwork assembly, the present invention also provides a high-strength alloy formwork assembly construction method, comprising:

[0021] (1) Select a tiling template of appropriate width according to the design requirements, and connect a tiling template to a corner template, so that the working surface of the tiling plate of the tiling template and the working surface of the corner template are on the same plane;

[0022] (2) Rotate the corner templates so that the angle between the two corner templates meets the design requirements;

[0023] (3) Connect another flat template to another corner template, and make the working surface of the flat plate of the flat template and the working surface of the corner template be on the same plane;

[0024] (4) Cut a sealing strip of appropriate size and stick it on the top of the third elastic member to cover the third elastic member to prevent dust and the like from entering the third elastic member;

[0025] (5) Check the sealing condition of the sealing strips on the two corner templates and adjust them accordingly to ensure that the two sealing strips are in a sealed contact state.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] During the use of the high-strength alloy formwork assembly of the present invention, since the sealing strips provided on the two corner formworks are always in a contact-sealed state, the side of the sealing strip extending out of the installation groove facing the working surface of the corner formwork is a plane and is on the same plane as the working surface of the corner formwork. Therefore, a flat and regular sharp corner can be formed at the external and internal corners of the structure. In the prior art, an arc surface is formed, and a flat and regular sharp corner cannot be formed.

[0028] Meanwhile, since the two corner formworks are always in a sealed contact state through the sealing strip, and the rotating structure is arranged on the side facing away from the working surface of the corner formwork, that is to say, when pouring, the sealed contact of the sealing strip enables the poured slurry and fine particles not to contact the rotating structure, thereby avoiding the problem that the slurry and fine particles enter the inside of the rotating structure and damage the rotating structure, and achieving the purpose of improving the service life of the rotating structure. Moreover, when the high-strength alloy formwork assembly is reused subsequently, there is no need to specifically clean the rotating structure. On the one hand, it reduces the workload of the staff and improves work efficiency; on the other hand, it saves resources (such as water resources and power resources consumed when cleaning the rotating structure).

[0029] Since the rotating structure of the present invention will never contact the concrete, slurry and other pouring materials during pouring, while avoiding the entry of slurry and particles into the inside of the rotating structure, it also does not have the problem of difficult demoulding caused by the immersion of slurry into the inside of the rotating structure, thereby preventing the external and internal corners from being damaged during the demoulding process and improving the forming quality of the external and internal corners.

[0030] During the use of the rotating structure of the high-strength alloy formwork assembly of the present invention, the rotation of one corner formwork is realized by the cooperation of the first arc-shaped arm and the sliding groove of the first arc-shaped plate, and the rotation of the other corner formwork is realized by the cooperation of the second arc-shaped arm and the sliding groove of the second arc-shaped plate, so as to realize the angle adjustment between the two corner formworks. Since one end of the first arc-shaped arm and the second arc-shaped arm are both inserted into the sliding groove, the first arc-shaped arm and the second arc-shaped arm are completely limited by the sliding groove and can only slide along the sliding groove. Compared with the prior art method of using a rotating shaft and a pin shaft to achieve rotational connection, on the premise of being able to realize the external and internal corners, the first elastic member and the second elastic member can provide good damping, making it easier to adjust the angle between the two corner formworks.

[0031] In the prior art, rotating connections are achieved through rotating shafts or pins. However, during pouring, the cast material (concrete, cement slurry, etc.) can enter the torsion springs or springs surrounding the rotating shaft. Once the cast material solidifies, it becomes bonded to the torsion springs or springs. Installing torsion springs or springs at both ends of the rotating shaft or pin inevitably increases the size of the ends, resulting in recessed areas at the external and internal corners, which in turn leads to poor molding quality at these corners. Therefore, the prior art cannot utilize springs or torsion springs to increase damping during rotation. In the prior art, rotating connections are achieved through the interaction of curved tongues and curved grooves (as exemplified in the background of this invention). Even if damping is increased by installing torsion springs or springs, the cast material can enter the rotating structure, preventing subsequent normal operation. Furthermore, even if structural improvements are implemented to prevent the cast material from contacting the torsion springs or springs, the complex structural design leads to high manufacturing costs. In summary, the arrangement and structural design of the rotating structure of the present invention improves the damping during rotation of the two corner formworks while offering the advantages of ingenious design and simple structure.

[0032] During use, the rotating structure of the high-strength alloy template assembly of the present invention can utilize the sliding between the first arc arm and the first arc plate, the sliding between the second arc arm and the second arc plate, and the sliding between the first arc plate and the second arc plate to jointly adjust the angle between the two corner templates. Therefore, under the premise of reducing the length of the first arc plate and the second arc plate, the length of the first arc arm and the second arc arm during movement can be increased as much as possible, thereby making the rotation angle range between the two corner templates wider, so as to meet the use of more angles of positive and negative angles.

Detailed implementation manners

[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] The serial numbers assigned to the components in this text itself, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0051] In the present invention, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0052] Combined with the attached Figure 1 To the attached Figure 12, the high-strength alloy formwork assembly of the present invention includes two corner formworks 200 and a rotating structure 300 for driving the two corner formworks 200 to rotate. An installation groove is provided on one side of the corner formwork 200, and the other side of the corner formwork 200 is connected to or for connecting to the flat formwork 100. That is to say, in some embodiments, the flat formwork 100 is not provided on the side of the corner formwork 200 facing away from the installation groove, and in some embodiments, the flat formwork 100 is provided on the side of the corner formwork 200 facing away from the installation groove. One side surface of the corner formwork 200 serves as the working surface of the formwork together with the side surface of the flat formwork 100; a sealing strip 220 is installed in the installation groove, and the sealing strips 220 on the two corner formworks 200 extend out of the installation groove and contact and seal each other, and the side surface of the sealing strip 200 extending out of the installation groove is on the same plane as the working surface of the corner formwork 200; the rotating structure 300 is arranged on the side surface opposite to the working surface of the corner formwork 200. That is to say, the rotating structure 300 is installed on one side surface of the corner formwork 200, and the other side surface of the corner formwork 200 facing away from the rotating structure 300 is the working surface.

[0053] In the specific implementation process, the corner formwork 200 is a flat plate, that is, one plane of the flat plate (i.e., the working surface) is used as a part of the formwork when pouring internal corners and external corners. In order to improve the strength of the flat plate, a plurality of corner reinforcing ribs 210 are arranged at intervals on the flat plate, and the overall strength of the corner formwork is improved by using the plurality of corner reinforcing ribs 210.

[0054] Among them, the working surface of the corner formwork 200 is used as a part of the formwork, the flat formwork 100 configured on the corner formwork 200 is also used as a part of the formwork, and the side surface of the sealing strip 220 extending out of the installation groove is also used as a part of the formwork. The working surface of the corner formwork 200, the working surface of the flat formwork 100, and the side surface of the sealing strip 220 extending out of the installation groove are on the same plane.

[0055] Combined with the attached Figure 4 and the attached Figure 5 , in some embodiments, one side in the left-right direction of the sealing strip 220 is inserted into the installation groove of the corner formwork 200, the other side in the left-right direction of the sealing strip 220 contacts and seals with another sealing strip 220, and the front side surface of the sealing strip 200 in the front-rear direction is on the same plane as the working surface of the corner formwork 200; and the rotating structure 300 is arranged on the corner formwork 200 at the rear side in the front-rear direction of the sealing strip 220.

[0056] Similarly, combined with the attached Figure 4 and the attached Figure 5, in the present invention, one side of the corner template 200 and the side of the flat template 100 together serve as the working surface of the template. That is to say, the working surface of the corner template 200 refers to the front side along the front and rear direction of the corner template 200, and the rotating structure 300 is arranged on the rear side in the front and rear direction of the corner template 200.

[0057] Combined with the attached Figure 4 and the attached Figure 5 , in the specific implementation process, the transverse cross-section of the installation groove is in the shape of a T, a trapezoid, a triangle, etc., so as to directly use the installation groove to position and install the sealing strip 220. Correspondingly, the sealing strip 220 has a plug that matches the installation groove, so as to directly use the mutual cooperation between the plug and the installation groove to realize the installation of the sealing strip 220.

[0058] Among them, in order to ensure that the sealing strip extending out of the installation groove has a flat surface, a part of the transverse cross-section of the sealing strip extending out of the installation groove is rectangular, so that the sealing strip extending out of the installation groove has a side surface in the same plane as the working surface of the corner template 200.

[0059] In the specific implementation process, in order to ensure that the installation groove of the corner template 200 does not affect the flatness of the working surface of the corner template, the installation groove extends in the direction towards the rotating structure, so as to use the space between the rotating structure 30 and the corner template 200 to accommodate the installation groove.

[0060] During the use of the high-strength alloy template assembly of the present invention, since the sealing strips provided on the two corner templates are always in a state of contact sealing, the side surface of the sealing strip extending out of the installation groove facing the working surface of the corner template is flat and in the same plane as the working surface of the corner template. Therefore, a flat and regular sharp corner can be formed at the external and internal corners of the building structure. In the prior art, an arc surface is formed, and a flat and regular sharp corner cannot be formed.

[0061] At the same time, since the two corner templates are always in a state of sealed contact through the sealing strip, and the rotating structure is arranged on the side surface facing away from the working surface of the corner template, that is to say, when pouring, the sealed contact of the sealing strip is used to prevent the poured slurry and fine particles from contacting the rotating structure, thereby avoiding the problem that the slurry and fine particles enter the inside of the rotating structure and damage the rotating structure, achieving the purpose of improving the service life of the rotating structure. And when the high-strength alloy template assembly is reused later, there is no need to specifically clean the rotating structure. On the one hand, it reduces the workload of the staff and improves work efficiency; on the other hand, it saves resources (such as water resources and power resources consumed when cleaning the rotating structure).

[0062] Since the rotating structure of the present invention will never come into contact with the casting materials such as concrete and cement slurry during casting, it can avoid the entry of slurry and particles into the rotating structure, and at the same time, it will not cause the problem of difficult demolding due to the immersion of slurry into the rotating structure. As described in the background art of the present invention, in the prior art, since the rotating structure (the cooperation of the rotating shaft, the arc-shaped convex tongue and the arc-shaped groove realizes rotation) will come into contact with the casting materials (such as concrete and cement slurry) during casting, after the casting materials penetrate into the rotating structure and solidify, the casting materials and the rotating structure will be fused together due to mutual embedding, which not only makes demolding difficult, but also easily damages the external corners and internal corners, further resulting in poor forming quality at the external corners and internal corners. Therefore, compared with the prior art, the present invention can also improve the forming quality of the external corners and internal corners and facilitate demolding.

[0063] Combined with the attached Figure 4 to the attached Figure 12 In some embodiments, as shown in the accompanying drawings, the rotating structure 300 includes a first arc-shaped arm 310 and a second arc-shaped arm 320. The first arc-shaped arm 310 and the second arc-shaped arm 320 are respectively arranged on two corner templates 200. The first arc-shaped arm 310 is provided with a first arc-shaped plate 380. One end of the first arc-shaped arm 310 is connected to one corner template 200, and the other end of the first arc-shaped arm 310 is inserted into the sliding groove 3100 of the first arc-shaped plate 380 and can slide in the sliding groove 3100. A first elastic member 350 is arranged in the sliding groove 3100 of the first arc-shaped plate 380. When the first arc-shaped arm 310 slides in the sliding groove 3100 of the first arc-shaped plate 380, it can squeeze the first elastic member 350 or the first elastic member 350 can squeeze the first arc-shaped arm 310. The second arc-shaped arm 320 is provided with a second arc-shaped plate 390. One end of the second arc-shaped arm 320 is connected to the other corner template 200, and the other end of the second arc-shaped arm 320 is inserted into the sliding groove 3100 of the second arc-shaped plate 390 and can slide in the sliding groove 3100. A second elastic member 360 is arranged in the sliding groove 3100 of the second arc-shaped plate 390. When the second arc-shaped arm 320 slides in the sliding groove 3100 of the second arc-shaped plate 390, it can squeeze the second elastic member 360 or the second elastic member 360 can squeeze the second arc-shaped arm 320. The first arc-shaped plate 380 and the second arc-shaped plate 390 are fixedly connected or slidably connected to each other. That is to say, in some embodiments, the first arc-shaped plate and the second arc-shaped plate are fixedly connected. In some embodiments, the first arc-shaped plate and the second arc-shaped plate can slide relative to each other.

[0064] Among them, when the first arc-shaped plate 380 and the second arc-shaped plate 390 are fixedly connected to each other, the sliding distance of the first arc-shaped arm within the first arc-shaped plate determines the rotation angle of this corner template, while the sliding distance of the second arc-shaped arm within the second arc-shaped plate determines the rotation angle of another corner template. Thus, the rotation angles of the two corner templates 200 are determined by the sliding distances of the first arc-shaped arm and the second arc-shaped arm.

[0065] In the specific implementation process, when the first arc-shaped plate 380 and the second arc-shaped plate 390 are fixedly connected, the first arc-shaped plate 380 and the second arc-shaped plate 390 are an integral structure, or form a whole after being connected to each other.

[0066] When the first arc-shaped plate 380 and the second arc-shaped plate 390 are slidably connected, the rotation angle between the two corner templates 200 is jointly controlled by the sliding of the first arc-shaped arm 310 along the sliding groove 3100 of the first arc-shaped plate 380, the sliding of the second arc-shaped arm 320 along the sliding groove 3100 of the second arc-shaped plate 390, and the sliding between the first arc-shaped plate 380 and the second arc-shaped plate 390.

[0067] During the use of the rotation structure of the high-strength alloy template assembly of the present invention, the rotation of one corner template is achieved by the cooperation between the first arc-shaped arm and the sliding groove of the first arc-shaped plate, while the rotation of the other corner template is achieved by the cooperation between the second arc-shaped arm and the sliding groove of the second arc-shaped plate, so as to realize the angle adjustment between the two corner templates. Since one end of each of the first arc-shaped arm and the second arc-shaped arm is inserted into the sliding groove, the first arc-shaped arm and the second arc-shaped arm are completely limited by the sliding groove and can only slide along the sliding groove. Compared with the prior art method of using a rotating shaft and a pin shaft to achieve rotational connection, on the premise of being able to achieve external corners and internal corners, the first elastic member and the second elastic member can provide good damping, making it easier to adjust the angle between the two corner templates.

[0068] In the prior art, rotating connections are achieved through rotating shafts or pins. However, during pouring, the cast material (concrete, cement slurry, etc.) can enter the torsion springs or springs surrounding the rotating shaft. Once the cast material solidifies, it becomes bonded to the torsion springs or springs. Installing torsion springs or springs at both ends of the rotating shaft or pin inevitably increases the size of the ends, resulting in recessed areas at the external and internal corners, which in turn leads to poor molding quality at these corners. Therefore, the prior art cannot utilize springs or torsion springs to increase damping during rotation. In the prior art, rotating connections are achieved through the interaction of curved tongues and curved grooves (as exemplified in the background of this invention). Even if damping is increased by installing torsion springs or springs, the cast material can enter the rotating structure, preventing subsequent normal operation. Furthermore, even if structural improvements are implemented to prevent the cast material from contacting the torsion springs or springs, the complex structural design leads to high manufacturing costs. In summary, the arrangement and structural design of the rotating structure of the present invention improves the damping during rotation of the two corner formworks while offering the advantages of ingenious design and simple structure.

[0069] As a preferred embodiment of the present invention, in some embodiments, the first curved plate 380 and the second curved plate 390 are slidably connected. Thus, the sliding between the first curved arm and the first curved plate, the sliding between the second curved arm and the second curved plate, and the sliding between the first curved plate and the second curved plate are used to jointly control the rotation angle between the two corner templates. In this case, the arc lengths of the first and second curved plates can be designed to be relatively shorter, thereby increasing the adjustment range of the rotation angle between the two corner templates and reducing the material and processing costs of the first and second curved plates.

[0070] Combined with attachment Figure 9 and attached Figure 10, in some embodiments, a first limiting groove 381 is provided on the side of the first arc-shaped plate 380 facing the second arc-shaped plate 390, and a second limiting groove 391 is provided on the side of the second arc-shaped plate 390 facing the first arc-shaped plate 380. A limiting pin 340 capable of sliding in the second limiting groove 391 is disposed at one end of the first arc-shaped plate 380 away from the first arc-shaped arm 310, and a limiting pin 340 capable of sliding in the first limiting groove 381 is disposed at one end of the second arc-shaped plate 390 away from the second arc-shaped arm 320. That is to say, the limiting pin 340 on the first arc-shaped plate 380 is arranged at one end of the first arc-shaped plate 380 away from the first arc-shaped arm 310, and the limiting pin 340 on the second arc-shaped plate 390 is arranged at one end of the second arc-shaped plate 390 away from the second arc-shaped arm 320, so that the two limiting pins 340 are symmetrically arranged. When the limiting pin 340 on the first arc-shaped plate 380 slides in the second limiting groove 391 on the second arc-shaped plate 390, the limiting pin 340 on the second arc-shaped plate 390 can slide in the first limiting groove 381 on the first arc-shaped plate 380, thereby making the sliding between the first arc-shaped plate 380 and the second arc-shaped plate 390 smoother.

[0071] Combined with the attached Figure 7 , in the specific implementation process, the limiting pin 340 on the first arc-shaped plate 380 is adapted to the second limiting groove 391 on the second arc-shaped plate 390, and the limiting pin 340 on the second arc-shaped plate 390 is adapted to the first limiting groove 381 on the first arc-shaped plate 380. Among them, since both the first arc-shaped plate 380 and the second arc-shaped plate 390 are arc-shaped, the first limiting groove 381 and the second limiting groove 391 are both arc-shaped. Therefore, when designing the shape of the limiting pin 340, it should be ensured that the limiting pin 340 on the first arc-shaped plate 380 can be adapted to the second limiting groove on the second arc-shaped plate, and the limiting pin on the second arc-shaped plate can be adapted to the first limiting groove on the first arc-shaped plate, so as to ensure the smooth sliding of the limiting pin in the first limiting groove and the second limiting groove.

[0072] Combined with the attached Figure 5 、Attached Figure 10 to attached Figure 12 , in some embodiments, a first retaining platform 382 and a second retaining platform 383 are respectively provided at both ends of the side of the first arc-shaped plate 380 facing the second arc-shaped plate 390, and a third retaining platform 392 and a fourth retaining platform 393 are respectively provided at both ends of the side of the second arc-shaped plate 390 facing the first arc-shaped plate 380. The first retaining platform 382, the second retaining platform 383, the third retaining platform 392 and the fourth retaining platform 393 interact with each other to jointly define the initial position and the sliding distance between the first arc-shaped plate 380 and the second arc-shaped plate 390.

[0073] Among them, as a preferred embodiment of the present invention, when the first stop 382 and the fourth stop 393 are in contact with each other for limiting, and the second stop 383 and the third stop 392 are in contact with each other for limiting, the angle between the two corner templates 200 is exactly 180°. In this state, it is the initial position of the first arc plate and the second arc plate. In this case, the extrusion effect between the sealing strips 200 of the two corner templates 200 is the smallest, the deformation of the sealing strip 220 is also the smallest, and the two corner templates 200 are in a flat state, which is also convenient for transportation and handling.

[0074] Combined with the attached Figure 5 , attached Figure 10 to attached Figure 12 , in some embodiments, the fourth stop 393 is located outside the first stop 382, and the second stop 383 is located outside the third stop 392, so that when the fourth stop 393 is in contact with the first stop 382 for limiting, the second stop 383 and the third stop 392 are just in contact with each other for limiting (that is, when the first stop and the fourth stop are in contact and at the same time the second stop and the third stop are in contact, there is no relative sliding between the first arc plate 380 and the second arc plate 390); thereby limiting the position of the first arc plate 380 and the second arc plate 390 when retracting. When the first arc plate 380 and the second arc plate 390 slide relative to each other, the first stop 382 on the first arc plate 380 moves towards the third stop 392 of the second arc plate 390, so as to use the first stop 382 and the third stop 392 to control the position of the first arc plate 380 and the second arc plate 390 when extending (that is, there is relative sliding between the first arc plate and the second arc plate).

[0075] In the specific implementation process, the positions between the first stop and the fourth stop, and the positions between the second stop and the third stop can be swapped. For example, the first stop is located outside the fourth stop, and the third stop is located outside the second stop, and it is still possible to achieve the contact and limiting between the first stop and the fourth stop, and the contact and limiting between the second stop and the third stop. When the first stop and the fourth stop are in contact and limited, the second stop and the third stop are just in contact with each other for limiting, thereby limiting the position of the first arc plate and the second arc plate when retracting. When the first arc plate and the second arc plate slide relative to the chute, the fourth stop on the second arc plate moves towards the second stop on the first arc plate, so as to use the second stop and the fourth stop to control the position of the first arc plate and the second arc plate when extending.

[0076] In the specific implementation process, the limit pins 340 on the first arc plate 380 are arranged above the first stop 382, and the limit pins 340 on the second arc plate 390 are arranged above the third stop 392.

[0077] In some other embodiments, the limiting pin 340 on the first arc-shaped plate 380 is arranged above the first retaining platform 382 and is an integral structure with the first retaining platform 382, while the limiting pin 340 on the second arc-shaped plate 390 is arranged above the third retaining platform 392 and is an integral structure with the third retaining platform 392.

[0078] Combined with the attached Figure 5 , attached Figure 10 to attached Figure 12 , a third elastic member 370 is provided between the first retaining platform 382 and the third retaining platform 392. Thus, when the first arc-shaped plate 380 and the second arc-shaped plate 390 slide relative to each other (whether retracting inward or extending outward), the third elastic member 370 can respectively apply the same magnitude of force to the first arc-shaped plate 380 and the second arc-shaped plate 390, so that the first arc-shaped plate 380 and the second arc-shaped plate 390 can move synchronously when sliding relative to each other.

[0079] Similarly, if the first retaining platform 382 is located outside the fourth retaining platform 393 and the third retaining platform 392 is located outside the second retaining platform 383, then the third elastic member 370 is arranged between the fourth retaining platform 393 and the second retaining platform 383.

[0080] That is to say, the third elastic member 370 is arranged between the two innermost retaining platforms on the first arc-shaped plate 380 and the second arc-shaped plate 390, and an installation space for installing the third elastic member 370 is formed between the two innermost retaining platforms on the first arc-shaped plate and the second arc-shaped plate. When the fourth retaining platform is located outside the first retaining platform and the second retaining platform is located outside the third retaining platform, the third elastic member is arranged between the first retaining platform and the third retaining platform. When the first retaining platform is located outside the fourth retaining platform and the third retaining platform is located outside the second retaining platform, the third elastic member is arranged between the fourth retaining platform and the second retaining platform.

[0081] As a preferred embodiment of the present invention, in some embodiments, the elastic coefficient of the third elastic member 370 is greater than the elastic coefficient of the first elastic member 350, and the elastic coefficient of the third elastic member 370 is greater than the elastic coefficient of the second elastic member 360. Thus, when adjusting the angle between the corner templates 200, first, the movement of the first arc-shaped arm 310 in the sliding groove 3100 on the first arc-shaped plate 380 and the movement of the second arc-shaped arm 320 in the sliding groove 3100 on the second arc-shaped plate 390 are used to adjust the angle between the two corner templates 200, and finally, the relative sliding between the first arc-shaped plate 380 and the second arc-shaped plate 390 is used to adjust the angle.

[0082] Preferably, the first elastic member 350 and the second elastic member 360 have the same elastic coefficient, so that when the two corner templates 200 are rotated, the acting forces applied to the two corner templates are equivalent, and thus it is more convenient for the operator to perform the operation.

[0083] Combined with the attached Figure 9 , in some embodiments, gaskets are provided between the first arc-shaped arm 310 and the second arc-shaped arm 320 and the corner template 200. The distance between the first arc-shaped arm 310 and the second arc-shaped arm 320 and the corner template 200 is adjusted by setting the number of gaskets, and then the rotation structure 300 at different distances from the corner template 200 is used to adjust the angle by which the corner template 200 can rotate. In the specific implementation process, the gasket used to connect the first arc-shaped arm 310 and the corner template 200 is called the first gasket 311, and the gasket used to connect the second arc-shaped arm 320 and the corner template 200 is called the second gasket 321.

[0084] Combined with the attached Figure 4 and the attached Figure 6 , in some embodiments, a sealing cover 330 for sealing the sliding groove 3100 is provided on the end faces of the first arc-shaped plate 380 and the second arc-shaped plate 390.

[0085] Combined with the attached Figure 1 and the attached Figure 2 , in some embodiments, the paving template 100 includes a paving plate surface 110. One surface of the paving plate surface 110 serves as the working surface of the template. A plurality of cross beams 130 and longitudinal beams 140 arranged in a staggered manner are provided on the side of the paving plate surface 110 facing away from the working surface. The periphery of the side of the paving plate surface facing away from the working surface is further covered with a side edge 120. A plurality of through holes are provided in the side edge 120 to facilitate reducing the overall weight by using the through holes and also to facilitate hoisting by using the through holes.

[0086] In some embodiments, a plurality of reinforcing plates 150 are also spaced on the side of the paving plate surface 110 facing away from the working surface to further improve the strength of the paving template 100.

[0087] In the specific implementation process, in order to improve the strength of the side 120, reinforcing ribs 160 are arranged at intervals or continuously on the side 120. Among them, the strength or the arrangement density of the cross beam 130 can be selected according to the height of the flat laying board surface 100. For example, the strength or density of the cross beam 130 arranged below the flat laying board surface 100 is higher, while the strength or sealing of the cross beam 130 arranged above the flat laying board surface 100 is relatively lower. Therefore, during the actual use of the formwork, the pressure borne by the lower end of the formwork is greater than that borne by the upper end of the formwork. Therefore, those skilled in the art can arrange the strength or density of the cross beam 130, as well as the quantity and length of the reinforcing ribs 160 according to the actual situation to ensure that the structural strength of the entire flat laying formwork 100 meets the use requirements, which will not be elaborated here.

[0088] In the specific implementation process, the corner formwork 200 and the flat laying formwork 100 are detachably connected, so as to install flat laying formworks 100 with different widths on the two corner formworks 200 according to different construction sites.

[0089] Based on the above high-strength alloy formwork assembly, the present invention also provides a construction method for a high-strength alloy formwork assembly, including:

[0090] (1) Select a flat laying formwork with a suitable width according to the design requirements, connect a flat laying formwork to one corner formwork, and make the working surface of the flat laying board surface of the flat laying formwork and the working surface of the corner formwork be on the same plane;

[0091] (2) Rotate the corner formwork so that the angle between the two corner formworks meets the design requirements;

[0092] (3) Then connect another flat laying formwork to another corner formwork, and make the working surface of the flat laying board surface of the flat laying formwork and the working surface of the corner formwork be on the same plane;

[0093] (4) Cut a sealing strip with a suitable size and paste it above the third elastic member to block the third elastic member to prevent dust and the like from entering the third elastic member;

[0094] (5) Check the sealing condition of the sealing strips on the two corner formworks and adjust according to the situation to ensure that the two sealing strips are in a sealed contact state.

[0095] Finally, fix the positions of the corner formwork and the flat laying formwork to prevent the angle between the two corner formworks from changing relatively during the process of pouring the external corner and the internal corner. Among them, the locking of the positions of the corner formwork and the flat laying formwork belongs to the prior art, and those skilled in the art can all understand and comprehend, which will not be elaborated here.

[0096] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0097] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of this application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of this application shall be subject to the appended claims.
