Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a single-sided formwork structure for an elevated floor. Background Technology

[0002] Ground floor spaces play a vital role in modern architecture. Serving as a transitional area between the building and outdoor space, they typically provide moisture insulation, ventilation, and heat dissipation, while also offering residents diverse activity spaces. With accelerating urbanization and rising demands for living environments, ground floor spaces, due to their unique spatial characteristics, have gradually become a focus for architects and designers, appearing in high-rise residential buildings, community centers, and educational buildings. Ground floor spaces not only offer economic and social benefits but also reduce energy consumption, aligning with eco-friendly development principles.

[0003] With the rapid development of urban construction, the use of single-sided wall formwork construction has become increasingly common in urban buildings due to limitations in construction site area and high waterproofing requirements for walls. The creation of elevated floors is also very common in underground construction. Current basement construction typically employs extremely high single-sided formwork, which is not only heavy but also involves a complex and cumbersome installation process, with subsequent dismantling posing a significant challenge.

[0004] Therefore, we need to propose a single-sided formwork structure for the elevated floor. Utility Model Content

[0005] The purpose of this utility model is to provide a single-sided formwork support structure for an elevated floor, in which the single-sided support and the heightening structure form an integral structure to improve the load-bearing capacity, enhance the stability of the formwork support, and ensure construction safety and quality, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A single-sided formwork structure for an elevated floor includes:

[0008] A single-sided support is provided, which abuts against one side of the template and is fixed by anchor bolts.

[0009] A construction platform is set at the bottom of the single-sided support to support the single-sided support, and the construction platform is supported by a disc-lock frame.

[0010] A reinforcing diagonal brace is installed on one side of the single-sided support to enhance the load-bearing capacity of the single-sided frame.

[0011] Preferably, the single-sided support also includes a heightening structure disposed at the upper end of the single-sided support. The heightening structure includes several sets of standard sections and a set of heightening sections. The several sets of standard sections are installed on the top of the single-sided support and connected end to end. The heightening section is connected to the upper end of the uppermost standard section. The combination of standard sections and heightening sections is used to meet the single-sided reinforcement requirements of different floor heights.

[0012] Preferably, the single-sided support and the heightening structure both abut against one side of the template, and the standard section and heightening section of the single-sided support and the heightening structure are all fixed to the back rib of the template through the back rib connector to form an integral whole, thereby improving the load-bearing capacity.

[0013] Preferably, the upper end of the reinforcing diagonal brace is connected to one side of the single-sided support, the lower end of the reinforcing diagonal brace abuts against one side of the crossbeam of the elevated floor, and the reinforcing diagonal brace is fully supported between the single-sided support and the crossbeam.

[0014] Preferably, the contact points between the reinforcing diagonal brace and the crossbeam of the overhead layer are padded with wooden blocks to protect the main body of the crossbeam.

[0015] Preferably, the disc-lock frame includes several sets of vertical bars, several sets of horizontal bars, and several sets of diagonal bars. The vertical bars provide vertical support, the horizontal bars provide horizontal support, and the vertical and horizontal bars are interwoven to form the frame. The diagonal bars are set within the rectangular grid formed by the horizontal and vertical bars to improve the support capacity. The upper end of the vertical bar is connected to the bottom of the construction platform, so that the disc-lock frame provides parallel support for the construction.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This utility model provides a technical solution:

[0024] A single-sided formwork structure for an elevated floor includes:

[0025] A single-sided support 1 rests against one side of the formwork and is secured by anchor bolts 3. The single-sided support 1 also includes a heightening structure located at its upper end. This heightening structure comprises several sets of standard sections 4 and one set of extension sections 5. The standard sections 4 are installed on top of the single-sided support 1 and connected end-to-end. The extension section 5 is connected to the uppermost standard section 4. The combination of standard sections 4 and extension sections 5 meets the single-sided reinforcement requirements for different floor heights. Both the single-sided support 1 and the heightening structure rest against one side of the formwork, and the single-sided support 1, the standard sections 4, and the extension section 5 are all fixed to the back ribs of the formwork via back rib connectors 6 to form a unified structure, thereby improving load-bearing capacity.

[0026] The single-sided support 1 is fixed in a suitable position by anchor bolts 3, abutting against one side of the formwork to provide lateral support. The height-adjusting structure is installed at the top of the single-sided support 1. According to different floor height requirements, several sets of standard sections 4 are connected end-to-end and installed on the top of the single-sided support 1. Then, the height-adjusting section 5 is connected to the uppermost standard section 4, allowing for flexible adjustment of the height of the single-sided support 1. The single-sided support 1, the standard sections 4 and height-adjusting section 5 of the height-adjusting structure are all fixed to the back ribs of the formwork via back rib connectors 6, connecting all parts into a single unit.

[0027] The above technical solution can meet the unilateral reinforcement requirements of different floor heights and adapt to diverse construction scenarios. Furthermore, the unilateral support 1 and the heightening structure form a unified structure, improving load-bearing capacity, enhancing the stability of the formwork support, and ensuring construction safety and quality.

[0028] Among them, the back rib connector 6 is tightly fixed to the template back rib and the support pole by bolts, and the contact surface is set with anti-slip texture to prevent loosening caused by vibration; it ensures the rigid connection between the single-sided support 1, the heightening structure and the template, avoids the slippage problem of traditional binding and fixing, improves the stability of the overall structure during the pouring process, and provides a reliable connection guarantee for ultra-high formwork.

[0029] Please see Figure 1 :

[0030] Construction platform 7 is set at the bottom of single-sided support 1 to support single-sided support 1. Construction platform 7 is supported by a disc-lock frame. The disc-lock frame includes several sets of vertical bars 8, several sets of horizontal bars 9 and several sets of diagonal bars 10. The vertical bars 8 provide vertical support, the horizontal bars 9 provide horizontal support, and the vertical bars 8 and horizontal bars 9 are interwoven to form the frame. The diagonal bars 10 are set in the rectangular grid formed by the horizontal bars 9 and vertical bars 8 to improve the support capacity. The upper end of the vertical bars 8 is connected to the bottom of construction platform 7 so that the disc-lock frame provides parallel support for construction.

[0031] The construction platform 7 is located at the bottom of the single-sided support 1 and is supported by a modular frame. Within the modular frame, vertical members 8 provide vertical support, bearing the vertical force of the construction platform 7 and the load above; horizontal members 9 provide horizontal support, ensuring the horizontal stability of the support. The vertical members 8 and horizontal members 9 intersect to form the basic frame structure. Diagonal members 10 are placed within the rectangular grid formed by the horizontal members 9 and vertical members 8, further enhancing the support capacity and stability of the entire modular frame through their diagonal support. The upper end of the vertical member 8 connects to the bottom of the construction platform 7, transferring the supporting force of the modular frame to the construction platform 7.

[0032] The above technical solution provides stable bottom support for the single-sided support 1, ensuring that the single-sided support 1 will not tilt or shift due to uneven force or excessive load during construction, thus ensuring the stability and safety of the entire single-sided formwork system.

[0033] Please see Figure 1 :

[0034] A reinforcing diagonal brace 2 is installed on one side of the single-sided support 1 to enhance the load-bearing capacity of the single-sided frame. The upper end of the reinforcing diagonal brace 2 is connected to one side of the single-sided support 1, and the lower end of the reinforcing diagonal brace 2 abuts against one side of the crossbeam of the elevated floor. The reinforcing diagonal brace 2 is fully supported between the single-sided support 1 and the crossbeam. Wooden blocks are placed at the contact points between the reinforcing diagonal brace 2 and the crossbeam of the elevated floor to protect the main body of the crossbeam.

[0035] The reinforcing diagonal brace 2 is installed on one side of the single-sided support 1, with its upper end connected to one side of the single-sided support 1 and its lower end pressing against one side of the crossbeam of the elevated floor. It is fully supported between the single-sided support 1 and the crossbeam, forming a stable triangular support structure. Wooden blocks are placed at the contact points between the reinforcing diagonal brace 2 and the crossbeam of the elevated floor, and the wooden blocks play a role in buffering and dispersing pressure.

[0036] The above technical solutions enhance the load-bearing capacity of the single-sided frame, improve the stability of the single-sided formwork system under lateral forces, and prevent deformation or instability of the single-sided support 1 during construction. The use of wooden supports protects the main structure of the crossbeams, preventing the reinforcing diagonal braces 2 from directly contacting and damaging them.

[0037] During the pouring process, the concrete is poured in layers from bottom to top. As the construction height increases, the single-sided support 1 is raised using a heightening structure to reduce the construction difficulty. As the preferred construction method, the concrete pouring speed is less than 1m / h, and each layer is poured in four times with a 30min interval between each pour.

[0038] Concrete should be poured in layers from bottom to top, with the pouring speed controlled at <1m / h and each pouring interval at 30 minutes (utilizing the initial setting characteristics of concrete to form layered solidification); as the pouring height increases, height-increasing sections should be installed simultaneously to match the support height of the support frame with the concrete pouring height (height difference ≤50cm).

[0039] Layered pouring reduces the lateral impact force of a single pour, preventing the formwork from deforming due to excessive instantaneous stress; simultaneous heightening reduces the amount of work at height (operators do not need to climb to the top for installation), reducing construction difficulty and minimizing the time interval between pours to prevent concrete hydration heat cracks.

[0040] In general, this approach reduces construction difficulty and ensures the quality of concrete pouring. Layered pouring and timely raising of the single-sided support1 make the construction process more orderly and controllable, avoiding construction difficulties and quality problems caused by pouring too high at once or insufficient support height. Controlling the pouring speed and the number and intervals of layered pours helps improve the density and uniformity of the concrete, reduces internal defects in the concrete, and ensures the quality of structures such as walls.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
