Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a template component with foldable exterior wall support. Background Technology

[0002] In recent years, the construction industry has continued to develop, and high-rise buildings have become increasingly common. This has placed higher demands on the formwork construction of components such as exterior wall structural columns and construction openings. In the construction of high-rise buildings, the formwork construction of exterior wall components is a crucial task, and its quality and efficiency directly affect the project's progress and overall quality.

[0003] During the building decoration phase, if the building is tall and the external scaffolding has been removed, the formwork construction of components such as external wall structural columns and construction openings will be difficult to carry out due to the lack of working platforms. Workers can usually only work on the inside of the external wall. For the problem of external wall formwork without scaffolding, there are currently two main solutions: one is a cantilevered formwork frame, which supports the outer formwork through cantilever beams, requiring additional support structures and is complex to install; the other is to use an integral lightweight aluminum alloy formwork, which is lighter in weight, but it is difficult to pass through the gaps between dense steel bars. Usually, it is necessary to transport the lightweight aluminum alloy formwork to the corresponding external formwork area through other windows.

[0004] In view of the above-mentioned related technologies, the inventors believe that there is a need to provide another formwork component for solving the problem of external wall formwork without scaffolding. Utility Model Content

[0005] In order to provide another technical solution for solving the problem of external wall formwork without scaffolding, this application provides a template component with foldable external wall formwork.

[0006] A template assembly with foldable exterior wall formwork includes an exterior wall formwork, an interior wall formwork, and a locking assembly for locking the exterior wall formwork and the interior wall formwork. The exterior wall formwork includes formwork units that are hinged sequentially along the height direction, and a hinge structure is provided between adjacent formwork units.

[0007] By adopting the above technical solution, the formwork units along the height direction are sequentially hinged to form the external wall formwork through the hinge structure, and the external wall formwork and the internal wall formwork are locked by the locking component, providing another technical solution for solving the problem of external wall formwork without scaffolding.

[0008] Optionally, the locking assembly includes a locking rod with one end detachably mounted to the external wall formwork and the other end penetrating the internal wall formwork, a mounting pad that fits against the outer side wall of the internal wall formwork and through which the locking rod passes, and a locking nut that is threaded onto the locking rod and used to press the mounting pad against the internal wall formwork.

[0009] By adopting the above technical solution, the basic structure of the locking assembly is disclosed. This structure, through the cooperation of the locking rod, the mounting plate, and the locking nut, allows the external wall formwork and the internal wall formwork to be locked together. One end of the locking rod can be detachably installed on the external wall formwork, facilitating the disassembly and installation of the formwork assembly. The mounting plate, when attached to the outer wall of the internal wall formwork, increases the stress-bearing area, preventing excessive local pressure from damaging the internal wall formwork. The locking nut presses the mounting plate tightly against the internal wall formwork, achieving stable locking of the internal and external wall formwork.

[0010] Optionally, one end of the locking rod near the external wall formwork is threaded onto the external wall formwork, and the external wall formwork has a first threaded hole for engaging with the locking rod.

[0011] By adopting the above technical solution, the locking rod is threaded into the first threaded hole of the external wall formwork, which makes the connection between the locking rod and the external wall formwork stable, convenient for disassembly and installation, and also facilitates the assembly and disassembly of the formwork assembly.

[0012] Optionally, each of the formwork units is provided with the first threaded hole, and the external wall formwork is also provided with a sealing end cap for sealing and covering the first threaded hole, the sealing end cap having a first threaded portion that mates with the first threaded hole.

[0013] By adopting the above technical solution, each formwork unit is provided with a first threaded hole, ensuring that the locking rod can be installed at any position of the formwork unit. The sealing end cap uses the first threaded part to cooperate with the first threaded hole to seal and cover the first threaded hole, which can prevent foreign objects from entering the first threaded hole and affecting the subsequent installation and use of the locking rod.

[0014] Optionally, the locking rod has a locking protrusion symmetrically arranged on the outer wall of one end near the external wall formwork. The external wall formwork has a locking through hole for inserting the locking rod. The inner wall of the locking through hole has a locking groove for engaging with the locking protrusion. The locking groove includes a first groove arranged circumferentially and a second groove connected to the first groove and arranged axially along the locking through hole. The second groove forms a locking socket on the inner wall of the external wall formwork.

[0015] By adopting the above technical solution, the locking rod can be stably installed by engaging the locking protrusion with the locking groove. The first groove arranged circumferentially and the second groove arranged axially along the locking through hole and connected to the first groove allow the locking rod to be smoothly inserted and tightly locked in a specific manner. The locking socket facilitates the quick insertion of the locking rod from the inner wall of the outer wall formwork.

[0016] Optionally, the outer side of the locking through hole has a second threaded section, and the external wall formwork is also provided with a sealing end cap for sealing and covering the locking through hole, the sealing end cap having a second threaded portion that mates with the second threaded section.

[0017] By adopting the above technical solution, the sealing end cap uses the second threaded part to cooperate with the second threaded section of the locking through hole to seal and cover the locking through hole, which can prevent foreign objects from entering the locking through hole and ensure the smooth installation and use of the locking rod.

[0018] Optionally, the hinge assembly includes a first hinge seat mounted on one of the formwork units, a first hinge shaft mounted on the first hinge seat, a second hinge seat mounted on another of the formwork units, a second hinge shaft mounted on the second hinge seat, and a hinge arm connecting the first hinge shaft and the second hinge shaft; the hinge arm has a first hinge sleeve rotatably mounted on the first hinge shaft and a second hinge sleeve connected to the first hinge sleeve and rotatably mounted on the second hinge shaft; the first hinge seat has a first arrangement groove for arranging the first hinge sleeve; the second hinge seat has a second arrangement groove for arranging the second hinge sleeve.

[0019] By adopting the above technical solution, the first hinge seat is used to install the first hinge shaft, and the second hinge seat is used to install the second hinge shaft. The first and second hinge shafts provide support points for the rotation of the hinge arm. The hinge arm is rotatably mounted on the first hinge shaft via a first hinge sleeve and on the second hinge shaft via a second hinge sleeve, enabling adjacent formwork units to rotate flexibly around the hinge arm to achieve a folding function. The first and second arrangement slots are used to arrange the first and second hinge sleeves, respectively, ensuring the stable installation of the hinge assembly.

[0020] Optionally, an elastic square sealing ring is fixed to the inner side of the external wall formwork, the square sealing ring having a sealing arrangement groove for arranging the hinge assembly.

[0021] By adopting the above technical solution, an elastic square sealing ring is fixed on the inner side of the external wall formwork. The sealing arrangement groove can accommodate the hinged components, play a sealing role, and prevent leakage during concrete pouring.

[0022] Optionally, the square sealing ring has a folded break at the sealing arrangement groove.

[0023] By adopting the above technical solution, the square sealing ring is provided with a folded break at the sealing arrangement groove, so that the square sealing ring can avoid the obstruction caused by the sealing arrangement groove when folding, ensuring smooth folding, while still achieving the sealing function, which is convenient for the folding and storage of the external wall formwork.

[0024] Optionally, the external wall support mold has an installation groove for arranging the square sealing ring.

[0025] By adopting the above technical solution, the square sealing ring is placed in the installation groove, which can play a sealing role and prevent grout leakage during the use of the external wall formwork.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A template assembly with foldable exterior wall formwork includes an exterior wall formwork, an interior wall formwork, and a locking assembly for locking the exterior wall formwork and the interior wall formwork; by sequentially hinged the formwork units of the exterior wall formwork along the height direction through a hinge structure to form the exterior wall formwork, and the exterior wall formwork and the interior wall formwork are locked by the locking assembly, providing another technical solution for solving the problem of exterior wall formwork without scaffolding; 2. By providing a first threaded hole in each formwork unit, the locking rod can be installed at any position in the formwork unit; 3. By fixing an elastic square sealing ring on the inside of the external wall formwork, the hinged components can be accommodated by the sealing arrangement groove, which can play a sealing role and prevent leakage during concrete pouring.

[0037] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0038] Example 1 This application discloses a template assembly with a foldable exterior wall formwork 1. (Refer to...) Figure 1 The formwork assembly with foldable exterior wall formwork includes an exterior wall formwork 1, an interior wall formwork 2, and a locking assembly 3 for locking the exterior wall formwork 1 and the interior wall formwork 2 together. The locking assembly 3 locks the exterior wall formwork 1 and the interior wall formwork 2 together, which not only ensures the stability of the formwork assembly during construction, but also provides another technical solution for solving the problem of exterior wall formwork 1 without scaffolding.

[0039] Reference Figure 2 The external wall formwork 1 consists of multiple formwork units 11 that are hinged sequentially along the height direction, and adjacent formwork units 11 are connected by a hinge structure 12. The formwork unit 11 adopts a flat plate structure, is made of steel, and its number can be determined according to the actual size of the formwork components in the construction.

[0040] Reference Figure 3 and Figure 4The hinge structure 12 includes a first hinge seat 121 mounted on a formwork unit 11, a first hinge shaft 1211 mounted on the first hinge seat 121, a second hinge seat 122 mounted on another formwork unit 11, a second hinge shaft 1221 mounted on the second hinge seat 122, and a hinge arm 123 connecting the first hinge shaft 1211 and the second hinge shaft 1221. The first hinge seat 121 and the second hinge seat 122 are typically cylindrical structures, and they are fixed to adjacent formwork units 11 respectively. The first hinge seat 121 and the second hinge seat 122 are fixed to each formwork unit 11 by welding. The first hinge shaft 1211 and the second hinge shaft 1221 are cylindrical rods that cooperate with the cylindrical structures, and are respectively mounted on the first hinge seat 121 and the second hinge seat 122.

[0041] Reference Figure 3 and Figure 4 The articulated arm 123 has a first articulated sleeve 1231 rotatably mounted on a first articulated shaft 1211 and a second articulated sleeve 1232 connected to the first articulated sleeve 1231 and rotatably mounted on a second articulated shaft 1221. The first articulated sleeve 1231 and the second articulated sleeve 1232 have cylindrical structures and are respectively fitted onto the first articulated shaft 1211 and the second articulated shaft 1221, enabling relative rotation. The first articulated seat 121 has a first arrangement groove 1212 for accommodating the first articulated sleeve 1231, and the second articulated seat has a second arrangement groove 1222 for accommodating the second articulated sleeve 1232. The arrangement grooves provide installation space for the articulated sleeves, making the rotation of the articulated arm 123 smoother.

[0042] Reference Figure 1 and Figure 5 In addition, an elastic square sealing ring 13 is fixed to the inner side of the external wall formwork 1. The square sealing ring 13 has a sealing arrangement groove 131 for arranging the hinge structure 12. The square sealing ring 13 is made of rubber and is fixed to the inner side of the external wall formwork 1.

[0043] Reference Figure 5 The square sealing ring 13 is provided with a folded break 132 at the sealing arrangement groove 131. When the external wall formwork 1 is folded, the folded break 132 can deform the square sealing ring 13 with the rotation of the formwork unit 11, and will not be damaged due to excessive stretching or compression.

[0044] Reference Figure 1 and Figure 5 The external wall formwork 1 also has an installation groove 14 for arranging the square sealing ring 13. The installation groove 14 can ensure that the square sealing ring 13 is accurately installed on the external wall formwork 1, so that its position is fixed and it can play a better sealing role.

[0045] Reference Figure 1The inner wall formwork 2 uses the same steel material as the outer wall formwork 1, and its overall dimensions are consistent with those of the outer wall formwork 1. In actual construction, the inner wall formwork 2 is arranged opposite to the outer wall formwork 1.

[0046] Reference Figure 6 and Figure 7 The locking assembly 3 includes a locking rod 31 with one end detachably mounted to the outer wall formwork 1 and the other end penetrating through the inner wall formwork 2; a mounting pad 32 fitted to the outer wall of the inner wall formwork 2 and through which the locking rod 31 passes; and a locking nut 33 threadedly mounted to the locking rod 31 and used to press the mounting pad 32 against the inner wall formwork 2. The end of the locking rod 31 closest to the outer wall formwork 1 is threadedly mounted to the outer wall formwork 1, and the outer wall formwork 1 has a first threaded hole 16 for engaging with the locking rod 31. In this embodiment, the inner wall formwork 2 is provided with a second threaded hole 21 corresponding to the first threaded hole 16 of the outer wall formwork 1. During installation, first, thread the locking rod 31 into the first threaded hole 16 of the outer wall formwork 1 for initial fixation; then, insert the locking rod 31 into the second threaded hole 21 of the inner wall formwork 2 to accurately position the inner and outer wall formwork 1; then, fit the mounting plate 32 onto the locking rod 31 and press it tightly against the outer side wall of the inner wall formwork 2; finally, tighten the locking nut 33 to press the mounting plate 32, thus completing the fixation of the entire formwork assembly.

[0047] Reference Figure 2 In addition, each formwork unit 11 is provided with a first threaded hole 16 to ensure that the locking rod 31 can be installed at any position of the formwork unit 11.

[0048] Reference Figure 7 The external wall formwork 1 is also provided with a sealing end cap 15 for sealing and covering the first threaded hole 16. The sealing end cap 15 has a first threaded portion 151 that mates with the first threaded hole 16. The sealing end cap 15 is made of the same steel material as the formwork unit 11. When a certain first threaded hole 16 is not needed, it can be sealed with the sealing end cap 15 to prevent debris from entering the threaded hole and affecting the subsequent installation of the locking rod 31.

[0049] The implementation principle of a template with foldable external wall formwork in this application embodiment is as follows: A template assembly with foldable external wall formwork includes an external wall formwork 1, an internal wall formwork 2, and a locking assembly 3 for locking the external wall formwork 1 and the internal wall formwork 2; by sequentially hinged the formwork units 11 of the external wall formwork 1 along the height direction through the hinge structure 12 to form the external wall formwork 1, and the external wall formwork 1 and the internal wall formwork 2 are locked by the locking assembly 3, another technical solution is provided for solving the problem of external wall formwork 1 without scaffolding.

[0050] Example 2 Compared with Embodiment 1, this embodiment is identical to the external wall formwork 1 structure of Embodiment 1 except for the different cooperation relationship between the locking rod 31 and each formwork unit 11.

[0051] Reference Figure 8 and Figure 9 The locking rod 31 has symmetrically arranged locking protrusions 311 on the outer wall near the outer wall formwork 1. The outer wall formwork 1 has a locking through hole 17 for inserting the locking rod 31. The inner wall of the locking through hole 17 has a locking groove for engaging with the locking protrusions 311. The locking groove includes a first groove 171 arranged circumferentially and a second groove 172 connected to the first groove 171 and arranged axially along the locking through hole 17. The second groove 172 forms a locking socket 18 on the inner wall of the outer wall formwork 1. When installing the locking rod 31, first align the locking protrusions 311 of the locking rod 31 with the locking socket 18 and insert it into the locking through hole 17. Then, push the locking rod 31 axially along the locking groove of the locking through hole 17 so that the locking protrusions 311 enter the second groove 172. Finally, rotate the locking rod 31 so that the locking protrusions 311 rotate into the first groove 171 to complete the engagement and fixation. This connection method is not only easy and quick to install and disassemble, but also ensures a stable and reliable connection.

[0052] Reference Figure 8 The locking through hole 17 has a second threaded section 173 on its outer side. The external wall formwork 1 is also provided with a sealing end cap 15 for sealing and covering the locking through hole 17. The sealing end cap 15 has a second threaded portion 19 that mates with the second threaded section 173. The sealing end cap 15 is made of the same steel material as the formwork unit 11. When a certain locking through hole 17 is not needed, it can be sealed with the sealing end cap 15 to prevent debris from entering the threaded hole and affecting the subsequent installation of the locking rod 31.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
