Description

Technical Field

[0001] This invention relates to the field of cast-in-place lintel construction technology, specifically to a suspended formwork structure for lintels based on pre-embedded sleeves. Background Technology

[0002] In construction projects, after the initial structural construction of passageways, doorways, and other locations is completed, some projects require the installation of cast-in-place lintels at the reserved openings, and the construction of walls on the lintels to reduce the size of the reserved openings.

[0003] Currently, the common practice on construction sites is to use a support frame in conjunction with formwork for the secondary structure construction of cast-in-place lintels. After installing the support frame at doorways and passageways, the ground-level bracing and uprights occupy these spaces, severely impacting material transport and personnel access, hindering construction organization, and affecting the construction schedule. Furthermore, the erection and dismantling of the support frame accounts for 45% of the total construction time for the lintel, and there is a risk of falls from height when using the support frame. The top of the reserved opening lacks a load-bearing support point, making it impossible to directly hang the formwork; if existing tie rod holes are used, positional deviations can cause the formwork to tilt.

[0004] It is evident that the current cast-in-place construction method for lintels still has room for improvement and should be optimized to enhance the stability of the formwork during lintel casting, ensuring the safety, reliability, and accuracy of the casting process. Therefore, a more reasonable technical solution is needed to address the existing technical problems. Summary of the Invention

[0005] In response to some of the problems existing in the prior art, this invention discloses a suspended formwork structure for lintels based on pre-embedded sleeves. The formwork components of the lintel are connected and set up through the suspension structure, so as to achieve stability and reliability in the lintel pouring process.

[0006] To achieve the above objectives, the suspended formwork system disclosed in this invention can adopt the following solution: A suspended formwork structure for lintels based on pre-embedded sleeves includes a pre-embedded structure set within a primary structure, on which several horizontal connecting channels are formed; several hangers, which correspond one-to-one with the connecting channels to form hangers, and the lintel casting formwork is connected and fixed through the hangers, forming a casting space for casting secondary structures between the lintel casting formwork and the primary structure.

[0007] The aforementioned suspended formwork structure provides a stress point above the cast-in-place lintel through a pre-embedded structure, and connects the formwork used for casting the lintel through a connector. In this way, when the lintel is being cast, the formwork is kept stable by the connector, eliminating the need to set up special support structures in passageways, doorways, and other locations, reducing the space occupied in passageways, doorways, and other locations, thereby simplifying the complex construction structure, which is conducive to simplifying the construction process and improving the convenience of operation.

[0008] Furthermore, the pre-embedded structure provides stress points for connecting and fixing the lower hangers. Its structure is not uniquely limited; optimization is proposed here, and one feasible option is suggested: the pre-embedded structure includes several pre-embedded pipes arranged horizontally within the primary structure. The pre-embedded height of the pipes is on the same plane and parallel to the outline of the primary structure. When using the above scheme, the pre-embedded pipes can be PVC pipes, pre-embedded during the primary structure pouring process.

[0009] Furthermore, the connector and the embedded pipe can be configured in various forms, and their structure is not limited to a single one. Here, we optimize and propose one feasible option: the connector includes a connecting rod that corresponds to the connecting channel, the connecting rod passing through the connecting channel and extending from both ends of the connecting channel; the connector also includes a hanger rod that connects to both ends of the connecting rod, and the connector includes a hanging structure bent at the lower end of the hanger rod, the hanging structure being used to hang the lintel casting formwork. When adopting the above scheme, the connecting rod is made of metal, the diameter of the connecting rod is slightly smaller than the diameter of the embedded pipe, and the surface is provided with an anti-slip and wear-resistant layer, such as a rubber layer.

[0010] Furthermore, the mating structure of the boom and connecting rod can adopt various methods. While achieving a stable and reliable connection, the structure is not limited to a single one. Here, we optimize and propose one feasible option: the upper end of the boom forms a hanging hole, and both ends of the connecting rod pass through the corresponding hanging hole. Clamping components are also provided at both ends of the connecting rod to clamp the upper end of the boom. When adopting the above scheme, the boom is made of metal, and the hanging hole is a circular hole corresponding to the connecting rod.

[0011] Furthermore, after installing a hanger rod on the connecting rod, a clamping assembly is used to adjust and clamp the hanger rod, preventing it from swaying and affecting the stability of the formwork, thus ensuring the structural reliability of the lintel casting. The clamping assembly can be constructed in various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the clamping assembly includes an inner nut and an outer nut set on the connecting rod. Both the inner nut and the outer nut are threaded into the connecting rod, and the hanger rod is clamped by adjusting the threads. When adopting the above scheme, the number of inner nuts and outer nuts is not limited to one; multiple nuts can be set and used to achieve anti-reverse.

[0012] Furthermore, the hanger can be constructed in various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the hanger includes L-shaped rods arranged opposite each other, with the horizontal sections of the L-shaped rods interlocking and extending / retracting in the horizontal direction. Using this scheme, the horizontal sections can be adjusted to meet the casting requirements of lintels of different widths.

[0013] Furthermore, when the L-shaped rods are mated, it is necessary to enhance the stability of the fit to ensure reliability under stress. The structure is not limited to a single type; here, an optimization is proposed, and one feasible option is suggested: a hanger consists of two mating L-shaped rods. The horizontal sections of the two L-shaped rods form a mating hole and a mating shaft. Reinforcing ribs are formed on the mating shaft, and corresponding grooves are provided within the mating hole. In this scheme, the reinforcing ribs are evenly spaced along the surface of the mating shaft, the mating hole can penetrate the horizontal section of the L-shaped rod, and the length of the groove is equal to the length of the mating hole.

[0014] Furthermore, the structure of the L-shaped rod can be optimized to achieve a suitable fitting height during longitudinal alignment, thereby maintaining height consistency when hoisting the lintel pouring formwork. One feasible optimization option is proposed here: the vertical section of the L-shaped rod includes an upper section and a lower section arranged coaxially. The upper and lower sections are connected and fitted by a threaded sleeve to adjust the length of the vertical section. In this scheme, the lower end of the upper section and the upper end of the lower section are both threaded, allowing them to move closer or further apart via the threaded sleeve, thus achieving height adjustment within a certain range.

[0015] Furthermore, the lintel casting template is used to define the forming structure of the lintel, and it can be constructed in various ways. Here, we optimize and propose one feasible option: the lintel casting template includes a bottom mold and side molds. The bottom mold is attached to the horizontal section of the L-shaped rod, and the side molds are attached to the vertical section of the L-shaped rod. When adopting the above scheme, the bottom mold and side molds can be integrally formed and directly laid on the hanger for fixing, or they can be adopted as separate structures, which are formed separately by binding.

[0016] Furthermore, since the L-shaped tube is used to bear weight, while meeting its strength requirements, its weight needs to be appropriately reduced. Its structure can be constructed in various forms; here, we optimize and propose one feasible option: the horizontal section of the L-shaped tube has a rectangular cross-section. When adopting the above solution, the connection between the horizontal and vertical sections of the L-shaped tube is integrally formed.

[0017] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this invention include: By setting up pre-embedded structures and providing stress points through primary structures, the lintel pouring formwork is fixed by suspension, enabling the lintel to be cast in place. This avoids the need to erect a large number of support structures at passageways, doorways, and other locations, which not only simplifies construction operations but also reduces the overall operation time during construction, improves construction efficiency, and eliminates safety hazards during construction.

[0024] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this embodiment.

[0025] In view of the fact that the existing technology requires the erection of supporting components for the pouring of lintels, and the supporting structure is complex, which is not conducive to improving construction efficiency, the following embodiments are optimized and overcome the defects of the existing technology.

[0026] Example like Figures 1-4 As shown, this embodiment provides a suspended formwork structure for lintels based on pre-embedded sleeves, including a pre-embedded structure 2 set in the primary structure 1, with several horizontal connecting channels formed on the pre-embedded structure 2; several hangers 4, which correspond one-to-one with the connecting channels to form hangers, and the lintel casting formwork 5 is connected and fixed through the hangers, forming a casting space for casting the secondary structure between the lintel casting formwork 5 and the primary structure 1.

[0027] The suspended formwork structure disclosed in this embodiment provides a stress point above the cast-in-place lintel through the pre-embedded structure 2, and connects the formwork used for casting the lintel through the hanger 4. In this way, when the lintel is cast, the formwork is kept stable by the hanger 4, eliminating the need to set up special support structures in passages, doorways, etc., reducing the space occupied in passages, doorways, etc., thereby simplifying the complex construction structure, which is conducive to simplifying the construction process and improving the convenience of operation.

[0028] The pre-embedded structure 2 is pre-installed to provide a stress point and connect and fix the lower hanging component 4. Its structure is not uniquely limited; this embodiment optimizes and adopts one feasible option: the pre-embedded structure 2 includes pre-embedded pipes, a number of which are arranged horizontally within the primary structure 1. The pre-embedded height of the pipes is on the same plane and parallel to the outline of the primary structure 1. When using the above scheme, the pre-embedded pipes can be PVC pipes, pre-embedded during the pouring process of the primary structure 1.

[0029] The hanger 4, in conjunction with the embedded pipe, can be constructed in various forms, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the hanger 4 includes a connecting rod 3 corresponding to the connecting channel, the connecting rod 3 passing through the connecting channel and extending from both ends of the connecting channel; the hanger 4 also includes a hanger rod connected to both ends of the connecting rod 3, and the hanger part includes a hanging structure bent at the lower end of the hanger rod, the hanging structure being used to hang the lintel casting formwork 5. When adopting the above scheme, the connecting rod 3 is a metal rod, the diameter of the connecting rod 3 is slightly smaller than the diameter of the embedded pipe, and the surface is provided with an anti-slip and wear-resistant layer, for example, a rubber layer.

[0030] Preferably, the connecting rod 3 in this embodiment can adopt a tie bolt structure.

[0031] The connection structure between the boom and the connecting rod 3 can be implemented in various ways. While achieving a stable and reliable connection, the structure is not limited to a single method. This embodiment optimizes the connection and adopts one feasible option: the upper end of the boom forms a hanging hole, and both ends of the connecting rod 3 are inserted into the hanging hole. Clamping components are also provided at both ends of the connecting rod 3 to clamp the upper end of the boom. When using the above solution, the boom is made of metal, and the hanging hole is a circular hole corresponding to the connecting rod 3.

[0032] After the hanger is installed on the connecting rod 3, the clamping assembly is used to adjust and clamp the hanger to prevent it from swaying and affecting the stability of the formwork, thus ensuring the structural reliability of the lintel casting. The clamping assembly can be constructed in various forms, and its structure is not limited to one. This embodiment optimizes and adopts one feasible option: the clamping assembly includes an inner nut and an outer nut set on the connecting rod 3. Both the inner nut and the outer nut are threaded into the connecting rod 3, and the hanger is clamped by adjusting the threads. When adopting the above scheme, the number of inner nuts and outer nuts is not limited to one; multiple nuts can be set and used to achieve anti-reverse.

[0033] The hanger can be constructed in various forms, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the hanger includes L-shaped rods arranged opposite each other, with the horizontal sections 402 of the L-shaped rods sleeved together and extending and retracting in the horizontal direction. When the above scheme is adopted, the horizontal sections 402 can be adjusted to meet the casting requirements of lintels of different widths.

[0034] Preferably, the two L-shaped rods are aligned and fitted together to form a U-shaped structure.

[0035] When L-shaped rods are mated, it is necessary to enhance the stability of the fit to ensure reliability under stress. The structure is not uniquely limited; this embodiment optimizes the fit and adopts one feasible option: a single rod comprises two mating L-shaped rods. The horizontal sections 402 of the two L-shaped rods form mating holes 403 and mating shafts 404. Reinforcing ribs 406 are formed on the mating shafts 404, and corresponding grooves 405 are provided within the mating holes 403. In this configuration, the reinforcing ribs 406 are evenly spaced along the surface of the mating shafts 404, the mating holes 403 can penetrate the horizontal sections 402 of the L-shaped rods, and the length of the grooves 405 is equal to the length of the mating holes 403.

[0036] The structure of the L-shaped rod can be further optimized to achieve a suitable fitting height during longitudinal alignment, thereby maintaining height consistency when hoisting the formwork 5 for the lintel. This embodiment optimizes the design and adopts one feasible option: the vertical section 401 of the L-shaped rod includes an upper section 401a and a lower section 401b coaxially arranged. The upper section 401a and the lower section 401b are connected and fitted by a threaded sleeve 6 to adjust the length of the vertical section 401. With this design, the lower end of the upper section 401a and the upper end of the lower section 401b are both threaded, allowing them to move closer or further apart via the threaded sleeve 6, thus achieving height adjustment within a certain range.

[0037] In some other solutions, the upper section 401a and the lower end can adopt a sleeve mating structure. After the upper section 401a and the lower section 401b are mated and connected, they are fixed by positioning holes and positioning pins 7.

[0038] The lintel casting template 5 is used to define the forming structure of the lintel. It can be constructed in various ways. This embodiment optimizes and adopts one feasible option: the lintel casting template 5 includes a bottom mold and side molds. The bottom mold is attached to the horizontal section 402 of the L-shaped rod, and the side molds are attached to the vertical section 401 of the L-shaped rod. When adopting the above scheme, the bottom mold and side molds can be integrally formed and directly laid on the hanger 4 for fixing, or they can be adopted as separate structures and formed by binding.

[0039] The L-shaped tube is used to bear weight. While meeting its strength requirements, it is necessary to appropriately reduce its weight. Its structure can be constructed in various forms. This embodiment optimizes and adopts one feasible option: the horizontal section 402 of the L-shaped tube has a rectangular cross-section. When adopting the above solution, the connection between the horizontal section 402 and the vertical section 401 of the L-shaped tube is integrally formed.

[0040] The above are the embodiments listed in this example; however, this example is not limited to the optional embodiments described above; those skilled in the art can arbitrarily combine the above methods to obtain other various embodiments; anyone can derive other various forms of embodiments under the guidance of this example.
