Description

Technical Field

[0001] This utility model relates to the field of construction technology of cast-in-place doorway lintels, and in particular to a support structure for cast-in-place doorway lintels that can adapt to multiple sizes. Background Technology

[0002] In the construction of cast-in-place lintels in buildings, the design of the support structure in the doorway area directly affects construction efficiency, forming quality, and traffic safety. Traditional support systems mostly rely on bottom-mounted steel pipe columns with top support structures or fixed-size frames. Although they can provide basic support, fixed-size prefabricated support frames are difficult to adapt to non-standard doorways (such as curved or irregular structures), often requiring customization or on-site modification. This wastes materials, weakens structural strength, and makes it difficult to reuse due to size differences, thus increasing construction costs.

[0003] In addition, the fixed ground support requires a dense cluster of columns to be erected on the ground of the doorway, forming a "forest of columns," which significantly reduces the space of the doorway, causing obstruction of material transportation and difficulty for workers to pass through. Secondly, the column structure is directly exposed to the construction flow line and is easily affected by external interference such as forklift scraping, vibration transmission or human collisions, which can cause the support frame to shift or tilt, resulting in horizontal displacement of the lintel formwork and inaccurate elevation, causing quality defects such as skewed openings and dimensional deviations after the concrete is formed. Utility Model Content

[0004] The purpose of this utility model is to provide a support structure for cast-in-place door openings that can adapt to multiple sizes, so as to solve the problem that the passage space of the door opening is reduced due to the support structure being placed on the ground, which leads to the obstruction of material transportation and thus causes the template to shift or become unstable.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lintel support structure for cast-in-place door openings adaptable to multiple sizes includes: a precast template and a bracket, wherein the precast template is erected on the top of the door opening; the precast template is mounted on the bracket, and the bracket supports the precast template; an adjustable support assembly, the adjustable support assembly having an overall triangular support structure, the top of the adjustable support assembly being rotatably connected to the bottom of the bracket; the adjustable support assembly being configured to adjust its width along the width direction of the door opening; the adjustable support assembly being installed inside the door opening, and the bottom of the adjustable support assembly being used to support the inner walls on both sides of the door opening.

[0007] Based on the above technical means, the adjustable support components are arranged close to the inner wall of the doorway, reducing the lateral space occupied and avoiding the construction passage blockage caused by traditional multi-member supports. This facilitates material transportation and personnel passage, and avoids the precast formwork shifting or becoming unstable due to impacts with the ground poles during transportation, thus ensuring the quality of the lintel after casting. Furthermore, the adjustable support components adopt a triangular support structure design, combined with the rotational connection between the top and the bracket, forming a stable support system with superior mechanical properties. This effectively disperses the load of the cast-in-place concrete, reduces the risk of formwork deformation, and ensures the quality of the pouring.

[0008] Secondly, by adjusting the telescopic extension of the support assembly along the width of the doorway, it can quickly adapt to doorways of different sizes without the need to replace or customize support components, significantly improving construction efficiency and reducing the cost of repeated equipment purchases. The rotatable connection between the top of the adjustment support assembly and the bottom of the bracket allows for fine-tuning of the angle during adjustment, avoiding stress concentration caused by forced installation.

[0009] Furthermore, the adjustable support assembly includes a first diagonal brace and a second diagonal brace. The tops of the first diagonal brace and the second diagonal brace are rotatably connected to the bracket, and the bottoms of the first diagonal brace and the second diagonal brace are respectively used to support the inner walls on both sides of the doorway to form a triangular support structure.

[0010] Based on the aforementioned technical means, a triangular support structure is formed by the first and second diagonal braces. Utilizing the principle of triangular geometric stability, the vertical load of the cast-in-place concrete is effectively decomposed into diagonal components, which are then transferred to the inner walls on both sides of the doorway. This significantly reduces the risk of deformation of the support structure and ensures the stability of the formwork during pouring. Secondly, the tops of both the first and second diagonal braces are rotatably connected to the bracket, allowing independent adjustment of the angle and unfolding width of the two braces. This adapts to both symmetrical doorways and asymmetrical doorways caused by construction errors or structural specialties, improving construction compatibility. Furthermore, the rotatable connection design of the first and second diagonal braces simplifies the adjustment process. Construction workers can quickly match the doorway width by rotating or unfolding the first and second diagonal braces without complex tools, significantly shortening installation time and improving construction efficiency.

[0011] Furthermore, the bracket includes a support base and a sleeve, the sleeve is fixed to the top of the support base, and an insertion post is formed below the precast template, the insertion post being inserted into the sleeve.

[0012] Based on the above technical means, the tight fit between the plug-in column and the sleeve forms a rigid connection, which effectively restricts the lateral displacement of the template. Combined with the supporting role of the bracket support, it ensures that the precast template remains horizontal and stable during the pouring process, avoiding tilting caused by vibration or load. Moreover, the plug-in fit between the plug-in column and the sleeve of the precast template eliminates the need for bolt fixing or welding during installation, greatly simplifying the operation process, shortening the construction time, and reducing the dependence on the technical skills of workers.

[0013] Furthermore, a first connecting lug is formed at the bottom of the support base, and the top ends of the first diagonal brace and the second diagonal brace are respectively rotatably connected to the first connecting lug.

[0014] According to the above-mentioned technical means, the top ends of the first and second diagonal braces are respectively rotatably connected to the first connecting lug, allowing for fine-tuning of the angle during adjustment and avoiding stress concentration caused by forced installation.

[0015] Furthermore, the adjusting support assembly also includes a first diagonal brace base and a second diagonal brace base, which are respectively used to be installed on the inner walls of both sides of the doorway. The bottom of the first diagonal brace is rotatably connected to the first diagonal brace base, and the bottom of the second diagonal brace is rotatably connected to the second diagonal brace base, so that the bottom of the first diagonal brace and the bottom of the second diagonal brace are respectively supported on the inner walls of both sides of the doorway through the first diagonal brace base and the second diagonal brace base.

[0016] According to the above-mentioned technical means, the first and second diagonal brace bases are fixed to the inner walls on both sides of the doorway, directly transferring the supporting force of the first and second diagonal braces to the load-bearing structure of the wall, avoiding local stress concentration that could lead to wall damage, and dispersing the load of the cast-in-place concrete to improve overall stability. The rotatable connection between the first and second diagonal braces and the first and second diagonal braces and the second diagonal brace base allows for flexible adjustment of the angles of the first and second diagonal braces in the vertical and horizontal directions, which can adapt to changes in the width of the doorway and compensate for construction errors or inclination of the inner wall, significantly enhancing construction compatibility.

[0017] Furthermore, it also includes fixing pins, which are used to fix the first diagonal brace base and the second diagonal brace base on the inner walls of both sides of the doorway.

[0018] Based on the aforementioned technical methods, the fixing nails firmly anchor the first and second diagonal brace bases to the inner wall of the doorway, preventing displacement of the first and second diagonal brace bases due to concrete pouring vibration or lateral loads, ensuring the overall stability of the triangular support structure, and preventing the risk of support failure during construction. Secondly, the fixing nails are easy to operate by pre-drilling holes or directly driving them into the wall, allowing for quick base fixing and reducing manual adjustment time; simultaneously, the rigid connection of the nails ensures a tight fit between the base and the wall, avoiding support angle deviations caused by installation errors.

[0019] Furthermore, a second connecting ear and a third connecting ear are respectively formed on the first inclined support base and the second inclined support base. The bottom end of the first inclined support rod is rotatably connected to the second connecting ear, and the bottom end of the second inclined support rod is rotatably connected to the third connecting ear.

[0020] Based on the above technical means, the rotational connection between the first diagonal brace and the second connecting ear, and the rotational connection between the second diagonal brace and the third connecting ear, allows the bottom ends of the first and second diagonal braces to be freely adjusted relative to the base, adapting to the tilt or unevenness of the inner walls on both sides of the doorway, ensuring that the adjustment support component fits tightly with the wall, and improving compatibility with different construction scenarios.

[0021] Furthermore, the adjusting support assembly also includes a first anti-slip component and a second anti-slip component. The first anti-slip component is located on the side of the first inclined support base near the inner wall of the doorway, and the second anti-slip component is located on the side of the second inclined support base near the inner wall of the doorway.

[0022] Based on the above technical means, the first and second anti-slip components directly contact the inner wall of the doorway. Through high-friction materials (such as rubber and polyurethane) or surface texture design, the friction between the first and second diagonal brace bases and the wall is greatly increased, preventing the support structure from slipping under concrete pouring vibration or lateral load, thus ensuring construction safety. In addition, the anti-slip components can compensate for unevenness or slight tilt of the wall surface. Through elastic deformation or soft material adhering to the inner wall, the uniformity of the contact surface is enhanced, avoiding instability of the support due to local gaps, and is compatible with various wall materials.

[0023] Furthermore, a first slot is formed on the first inclined support base, and the first anti-slip component is disposed in the first slot.

[0024] According to the above technical means, the first slot formed on the first inclined base provides a standardized installation space for the first anti-slip component. Through physical limiting, it ensures that the first anti-slip component is always in the preset position, avoiding displacement or detachment caused by construction vibration or lateral load, and enhancing the reliability of the anti-slip effect.

[0025] Furthermore, a second groove is formed on the second inclined support base, and the second anti-slip component is disposed in the second groove.

[0026] According to the above technical means, the second slot formed on the second inclined support base provides a standardized installation space for the second anti-slip component. Through physical limiting, it ensures that the second anti-slip component is always in the preset position, avoiding displacement or detachment caused by construction vibration or lateral load, and enhancing the reliability of the anti-slip effect.

[0027] The beneficial effects achieved by this utility model are:

[0028] This invention reduces lateral space occupation by adjusting the support components to fit closely against the inner wall of the doorway, avoiding the construction passage blockage caused by traditional multi-member supports, facilitating material transportation and personnel passage, and preventing the precast formwork from shifting or becoming unstable due to impacts with the ground poles during transportation, thus ensuring the quality of the lintel after casting. Furthermore, the adjustable support components adopt a triangular support structure design, combined with the rotational connection between the top and the bracket, forming a stable support system with superior mechanical properties, effectively distributing the load of the cast-in-place concrete, reducing the risk of formwork deformation, and ensuring the quality of the casting.

[0029] Secondly, by adjusting the telescopic extension of the support assembly along the width of the doorway, it can quickly adapt to doorways of different sizes without the need to replace or customize support components, significantly improving construction efficiency and reducing the cost of repeated equipment purchases. The rotatable connection between the top of the adjustment support assembly and the bottom of the bracket allows for fine-tuning of the angle during adjustment, avoiding stress concentration caused by forced installation.

[0045] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0046] like Figure 1 and Figure 2 As shown, this embodiment proposes a cast-in-place doorway lintel support structure adaptable to multiple sizes, including: a precast template 2 and a bracket 3. The precast template 2 is used to be erected on the top of the doorway 1; the precast template 2 is installed on the bracket 3, and the bracket 3 is used to support the precast template 2; an adjustable support assembly 4, which is a triangular support structure, with the top of the adjustable support assembly 4 rotatably connected to the bottom of the bracket 3; the adjustable support assembly 4 is configured to adjust its width along the width direction of the doorway 1; the adjustable support assembly 4 is used to be installed inside the doorway 1, and the bottom of the adjustable support assembly 4 is used to support the inner walls on both sides of the doorway 1.

[0047] The specific steps for using the support structure designed above are as follows:

[0048] 1. Construction preparation: Measure the width and height of the lintel of doorway 1, determine the size of precast formwork 2, and prepare the supporting structural components (precast formwork 2, bracket 3, and adjustable support assembly 4).

[0049] 2. Assemble the support structure: Assemble the bracket 3 with the adjustable support component 4 so that the adjustable support component can adjust its width to match the width of the doorway 1.

[0050] 3. Install the support structure: First, place the precast template 2 on top of the doorway 1. Then, install the assembled bracket 3 and the adjusting support assembly 4 onto the precast template 2. Rotate the adjusting support assembly 4 along the width direction of the doorway 1 to match the width of the doorway 1. Finally, fix the bottom of the adjusting support assembly 4 to the inner walls on both sides of the doorway 1 using fasteners.

[0051] 4. Reinforcement and safety check: Confirm that all rotating connections are secure (e.g., using pins or fastening nuts).

[0052] 5. Concrete pouring and curing: Pour concrete on precast formwork 2, avoiding impact on the supporting structure during the process.

[0053] After the concrete has hardened, the adjustment support assembly 4, bracket 3 and template are disassembled in sequence, and the components are recycled for reuse.

[0054] The adjusting support component 4 is arranged close to the inner wall of the doorway 1, reducing the lateral space occupied and avoiding the construction passage blockage caused by traditional multi-member support. This facilitates material transportation and personnel passage, and prevents the precast formwork 2 from shifting or becoming unstable due to impact with the ground pole during transportation, thus ensuring the quality of the lintel after casting. Furthermore, the adjusting support component 4 adopts a triangular support structure design, combined with the rotational connection between the top and the bracket 3, forming a stable support system with superior mechanical properties. This effectively disperses the load of the cast-in-place concrete, reduces the risk of formwork deformation, and ensures the quality of the casting.

[0055] Secondly, by adjusting the telescopic extension of the support component 4 along the width of the doorway 1, it can quickly adapt to doorways 1 of different sizes without the need to replace or customize support parts, significantly improving construction efficiency and reducing the cost of repeated equipment purchases. The rotatable connection between the top of the adjustment support component 4 and the bottom of the bracket 3 allows for fine-tuning of the angle during adjustment, avoiding stress concentration caused by forced installation.

[0056] like Figure 1 As shown, in this embodiment, the adjustable support assembly 4 includes a first diagonal brace 41 and a second diagonal brace 42. The tops of the first diagonal brace 41 and the second diagonal brace 42 are rotatably connected to the bracket 3, and the bottoms of the first diagonal brace 41 and the second diagonal brace 42 are respectively used to support the inner walls on both sides of the doorway 1 to form a triangular support structure.

[0057] The first diagonal brace 41 and the second diagonal brace 42 form a triangular support structure. Utilizing the principle of triangular geometric stability, the vertical load of the cast-in-place concrete is effectively decomposed into diagonal components, which are then transferred to the inner walls on both sides of the doorway 1. This significantly reduces the risk of deformation of the support structure and ensures the stability of the formwork during pouring. Secondly, the tops of both the first diagonal brace 41 and the second diagonal brace 42 are rotatably connected to the bracket 3, allowing independent adjustment of the angle and unfolding width of the two braces. This adapts to both symmetrical doorways 1 and asymmetrical doorways 1 caused by construction errors or structural specialties, improving construction compatibility. Furthermore, the rotatable connection design of the first diagonal brace 41 and the second diagonal brace 42 simplifies the adjustment process. Construction workers can quickly match the width of the doorway 1 by rotating or unfolding the first diagonal brace 41 and the second diagonal brace 42 without complex tools, significantly shortening installation time and improving construction efficiency.

[0058] like Figure 1 As shown, in this embodiment, the bracket 3 includes a support base 31 and a sleeve 32. The sleeve 32 is fixed on the top of the support base 31, and an insertion post 21 is formed below the prefabricated template 2. The insertion post 21 is inserted into the sleeve 32.

[0059] To prevent the formwork from rotating or coming off due to the lateral pressure of the concrete during the pouring process, in this embodiment, the contact surface between the inner wall of the sleeve 32 and the plug-in column 21 can be designed with anti-slip texture or a limit pin can be added to ensure construction safety.

[0060] The tight fit between the plug-in column 21 and the sleeve 32 forms a rigid connection, effectively limiting the lateral displacement of the template. Combined with the supporting role of the bracket 3 support seat 31, it ensures that the precast template 2 remains horizontal and stable during the pouring process, avoiding tilting caused by vibration or load. Furthermore, the plug-in fit between the plug-in column 21 and the sleeve 32 of the precast template 2 eliminates the need for bolt fixing or welding during installation, greatly simplifying the operation process, shortening the construction time, and reducing the dependence on the skill level of workers.

[0061] like Figure 1 As shown, in this embodiment, a first connecting ear 311 is formed at the bottom of the support base 31, and the top ends of the first diagonal brace 41 and the second diagonal brace 42 are respectively rotatably connected to the first connecting ear 311.

[0062] The top ends of the first diagonal brace 41 and the second diagonal brace 42 are rotatably connected to the first connecting lug 311, allowing for fine-tuning of the angle during adjustment and avoiding stress concentration caused by forced installation.

[0063] like Figure 1 and Figure 2 As shown, in this embodiment, the adjusting support assembly 4 further includes a first inclined support base 43 and a second inclined support base 44. The first inclined support base 43 and the second inclined support base 44 are respectively used to be installed on the inner walls on both sides of the door opening 1. The bottom of the first inclined support rod 41 is rotatably connected to the first inclined support base 43, and the bottom of the second inclined support rod 42 is rotatably connected to the second inclined support base 44, so that the bottom of the first inclined support rod 41 and the bottom of the second inclined support rod 42 are respectively supported on the inner walls on both sides of the door opening 1 by the first inclined support base 43 and the second inclined support base 44.

[0064] The first diagonal brace base 43 and the second diagonal brace base 44 are fixed to the inner walls on both sides of the doorway 1, directly transferring the supporting force of the first diagonal brace 41 and the second diagonal brace 42 to the load-bearing structure of the wall, avoiding local stress concentration that could lead to wall damage, and dispersing the load of the cast-in-place concrete to improve overall stability. The rotatable connection between the first diagonal brace 41 and the first diagonal brace base 43 and the second diagonal brace 42 and the second diagonal brace base 44 allows the first diagonal brace 41 and the second diagonal brace 42 to flexibly adjust their angles in the vertical and horizontal directions, which can adapt to changes in the width of the doorway 1 and compensate for construction errors or inclination of the inner wall, significantly enhancing construction compatibility.

[0065] like Figure 1 As shown, in this embodiment, a fixing nail 5 is also included, which is used to fix the first inclined support base 43 and the second inclined support base 44 on the inner walls on both sides of the door opening 1.

[0066] To expand the applicability of the structure, in this embodiment, the fixing nail 5 can be selected according to the wall type (such as concrete, brick masonry or lightweight partition wall) to select the appropriate specification (such as expansion bolt, self-tapping screw or chemical anchor).

[0067] To minimize permanent damage to the wall, in this embodiment, the fixing nail 5 can be designed as a detachable nail, such as a bolt connection.

[0068] The fixing nails 5 firmly anchor the first diagonal brace base 43 and the second diagonal brace base 44 to the inner wall of the doorway 1, preventing displacement of the first diagonal brace base 43 and the second diagonal brace base 44 due to concrete pouring vibration or lateral loads, ensuring the overall stability of the triangular support structure and preventing the risk of support failure during construction. Secondly, the fixing nails 5 are easy to operate by pre-drilling holes or directly driving them into the wall, allowing for quick base fixing and reducing manual adjustment time; at the same time, the rigid connection of the nails ensures a tight fit between the base and the wall, avoiding support angle deviation caused by installation errors.

[0069] like Figure 3 and Figure 4 As shown, in this embodiment, a second connecting ear 431 and a third connecting ear 441 are respectively formed on the first inclined support base 43 and the second inclined support base 44. The bottom end of the first inclined support rod 41 is rotatably connected to the second connecting ear 431, and the bottom end of the second inclined support rod 42 is rotatably connected to the third connecting ear 441.

[0070] By rotating the first diagonal brace 41 to the second connecting ear 431 and the second diagonal brace 42 to the third connecting ear 441, the bottom ends of the first diagonal brace 41 and the second diagonal brace 42 can be freely adjusted to adjust their relative angles with the base, adapting to the tilt or unevenness of the inner walls on both sides of the doorway 1, ensuring that the adjustment support assembly 4 fits tightly with the wall, and improving compatibility with different construction scenarios.

[0071] like Figures 1-4 As shown, in this embodiment, the adjusting support assembly 4 further includes a first anti-slip component 45 and a second anti-slip component 46. The first anti-slip component 45 is located on the side of the first inclined support base 43 near the inner wall of the doorway 1, and the second anti-slip component 46 is located on the side of the second inclined support base 44 near the inner wall of the doorway 1.

[0072] Preferably, both the first anti-slip component 45 and the second anti-slip component 46 are made of rubber.

[0073] The first anti-slip component 45 and the second anti-slip component 46 directly contact the inner wall of the doorway 1. Through high-friction materials (such as rubber and polyurethane) or surface texture design, they significantly increase the friction between the first diagonal brace base 43 and the second diagonal brace base 44 and the wall, preventing the support structure from slipping under concrete pouring vibration or lateral load, and ensuring construction safety. In addition, the anti-slip components can compensate for unevenness or slight tilt of the wall surface. Through elastic deformation or soft material to adhere to the inner wall, they enhance the uniformity of the contact surface, avoid instability of the support due to local gaps, and are compatible with various wall materials.

[0074] like Figure 3 and Figure 4 As shown, in this embodiment, a first slot 432 is formed on the first inclined support base 43, and a first anti-slip member 45 is disposed in the first slot.

[0075] The first slot 432 formed on the first inclined base 43 provides a standardized installation space for the first anti-slip component 45. Through physical limiting, it ensures that the first anti-slip component 45 is always in the preset position, avoiding displacement or detachment caused by construction vibration or lateral load, and enhancing the reliability of the anti-slip effect.

[0076] like Figure 3 and Figure 4 As shown, in this embodiment, a second slot 442 is formed on the second inclined base 44, and a second anti-slip member 46 is disposed in the second slot.

[0077] The second slot 442 formed on the second inclined base 44 provides a standardized installation space for the second anti-slip component 46. Through physical limiting, it ensures that the second anti-slip component 46 is always in the preset position, avoiding displacement or detachment caused by construction vibration or lateral load, and enhancing the reliability of the anti-slip effect.

[0078] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
