Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology and engineering equipment technology, and in particular to a screwless triangular support device for concrete beams. Background Technology

[0002] In traditional building construction, concrete beam formwork systems, which mainly use square steel pipes and tie bolts, are widely used because of their intuitive structure and readily available materials.

[0003] However, as building structures become increasingly larger, higher, and more complex, this type of traditional support system has some shortcomings:

[0004] 1. The formwork has numerous connecting components, such as dense tie rods, requiring extensive manual installation and adjustment, which severely restricts the construction period. Secondly, traditional solutions often use hollow square steel as the main keel, which lacks rigidity and is prone to deflection and displacement, affecting the quality of concrete molding.

[0005] 2. Traditional support systems lack a systematic and stable structure, resulting in low overall lateral stiffness and a risk of support collapse. Furthermore, the materials used in these systems are difficult to recycle and have low reuse rates, leading to increased overall material costs for the project. In summary, concrete beam formwork systems are not only inefficient and lack structural stiffness, but also pose significant safety hazards and have low material reuse rates.

[0006] Based on this, a screwless triangular support device for concrete beams is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a screwless triangular support device for concrete beams to solve the problems mentioned in the background art.

[0008] The technical solution of this utility model is: a screwless triangular support device for concrete beams, comprising:

[0009] Templates are used to shape concrete beams;

[0010] Secondary keels are installed below the template to support it.

[0011] The main keel is located below the secondary keel and is used to support the secondary keel and transfer the load to the lower support structure.

[0012] A fixed square tube assembly includes at least one set of longitudinal fixed square tubes and at least one set of vertical fixed square tubes. The longitudinal fixed square tubes are arranged along the length of the concrete beam on the side of the formwork, and the vertical fixed square tubes are arranged perpendicular to the longitudinal fixed square tubes.

[0013] The bracket has an L-shaped structure, with its horizontal side supported on the main keel or lower support structure, and its vertical side abutting against and fixedly connected to the outer side of the vertical fixed square tube.

[0014] In some embodiments, the template, the fixed square tube assembly, and the bracket together form a stable triangular support structure. The main keel is made of channel steel, the secondary keel and the fixed square tube assembly are made of hollow square steel tubes, and the template is made of plywood.

[0015] In some embodiments, the bracket is a customized L-shaped component that is detachably connected to the vertical fixed square tube by fasteners, and the bracket is arranged at intervals along the length of the concrete beam.

[0016] In some embodiments, the lower support structure includes a disc-lock scaffold, which includes a base, disc-lock uprights, disc-lock horizontal bars, horizontal supports, and diagonal supports; the main keel is fixed to the top of the disc-lock scaffold by U-shaped brackets.

[0017] In some embodiments, the main keel, secondary keel, fixed square tube assembly, and bracket are all detachable modular components that can be disassembled in whole or in part and reused repeatedly.

[0018] Compared with existing technologies, the significant advantages of this invention are:

[0019] Firstly, all components in this utility model are standardized parts, requiring no welding or cutting, resulting in a high assembly rate, rapid assembly and disassembly, and a rational arrangement of primary and secondary keels and formwork to form a unified force-bearing system. This eliminates the need for repeated positioning and adjustments using tie bolts, improving work continuity and formwork forming quality. The component design emphasizes lightweight and portability, facilitating hoisting, handling, and reuse, significantly reducing construction time and improving construction efficiency.

[0020] Secondly, this utility model uses channel steel as the main keel, replacing the traditional square steel pipe, which significantly improves the overall bending stiffness and load-bearing capacity, preventing deflection and deformation during the pouring process. At the same time, the modular customized bracket and fixed square tube form a stable spatial structure, effectively improving stability, strengthening the overall structural stiffness and anti-lateral displacement ability, and enhancing the structural performance of the device.

[0021] Thirdly, in this utility model, the main components are assembled on the ground, reducing on-site high-altitude operations and improving operational safety. Simultaneously, the standardized assembly process reduces human error, ensuring that the dimensions, flatness, and verticality of the concrete beams meet specifications. The modular structure facilitates adjustment and combination, adapting to various structural dimensions and formwork requirements for complex components such as curved beams and variable cross-section beams. The modular design also allows for multiple reuses on-site, reducing material waste and on-site storage pressure, significantly lowering costs. Efficient installation and dismantling also save considerable labor and time, resulting in high economic efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0028] This utility model provides an improved, screwless triangular support device for concrete beams. The technical solution of this utility model is as follows:

[0029] like Figures 1-2 As shown, a screwless triangular support device for concrete beams includes:

[0030] Template 1, used for molding concrete beams;

[0031] Secondary keel 2 is installed below template 1 to support template 1;

[0032] The main keel 3, located below the secondary keel 2, supports the secondary keel 2 and transfers the load to the lower supporting structure. The main keel 3, as the primary load-bearing component, uses U-shaped channel steel and is arranged parallel to the bottom of the beam. The secondary keel 2, as a distribution component, uses rectangular hollow square steel tubes and is arranged vertically above the main keel 3.

[0033] The fixed square tube assembly includes at least one set of longitudinal fixed square tubes 4 and at least one set of vertical fixed square tubes 5. The longitudinal fixed square tubes 4 are arranged along the length of the concrete beam on the side of the formwork 1, and the vertical fixed square tubes 5 are arranged perpendicular to the longitudinal fixed square tubes 4.

[0034] The bracket 6 is an L-shaped structure. Its horizontal side is supported on the main keel 3 or the lower support structure, and its vertical side abuts against and is fixedly connected to the outside of the vertical fixed square tube 5.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the template 1, the fixed square tube assembly, and the bracket 6 together form a stable triangular support structure. The main keel 3 is made of channel steel, and the secondary keel 2 and the fixed square tube assembly are made of hollow square steel tubes. The fixed square tubes are divided into longitudinal fixed square tubes 4 and vertical fixed square tubes 5, which are made of hollow square steel tubes to strengthen the edges and structural connections of the template 1 and improve the overall rigidity. The template 1 is made of plywood.

[0036] The bracket 6 is a customized L-shaped component that is detachably connected to the vertical fixed square tube 5 through fasteners. The bracket 6 is arranged at intervals along the length of the concrete beam.

[0037] like Figure 1 As shown, in one embodiment, the lower support structure includes a disc-lock scaffold, which includes a base support 8, disc-lock uprights 10, disc-lock horizontal bars 9, horizontal supports 12, and diagonal supports 11; the main keel 3 is fixed to the top of the disc-lock scaffold by U-shaped brackets 7.

[0038] The main keel 3, secondary keel 2, fixed square tube assembly and bracket 6 are all detachable modular components that can be disassembled in whole or in part and reused repeatedly.

[0039] The specific working method is as follows: First, on the completed lower floor slab or foundation, the construction site is cleaned and precise measurements and lines are drawn.

[0040] Next, according to the construction plan and the layout position, the base support 8 is laid and initially leveled, the disc buckle uprights 10 are erected, and the uprights are connected into a stable overall frame through the disc buckle crossbars 9. Horizontal supports 12 and diagonal supports 11 are installed inside the support system to enhance the overall stability of the support frame. Finally, the elevation of the top of the support frame is finely adjusted to ensure that it meets the design elevation of the bottom of the concrete beam.

[0041] Two channel steels are arranged parallel to each other as main keels 3 on the top of the leveled disc-lock support frame. The main keels 3 are reliably fixed to the disc-lock uprights 10 with standard fasteners such as U-shaped brackets 7 to ensure accurate positioning and firm installation. On the main keels 3, multiple hollow square steel pipes are arranged at equal intervals perpendicular to the main keels 3 as secondary keels 2. The secondary keels 2 are fixed to the main keels 3 with fasteners or positioning clamps to form a stable load-bearing platform. Plywood is used as the bottom formwork 1 of the beam and laid on the secondary keels 2 to complete the support of the bottom forming surface of the concrete beam.

[0042] The pre-cut beam side formwork 1 is erected on both sides of the beam bottom formwork 1. Longitudinal fixing square tubes 4 are installed along the upper and lower edges of the outer side of the beam side formwork 1. Between the longitudinal fixing square tubes 4 on both sides, several vertical fixing square tubes 5 are installed vertically to form a reinforcing grid for the beam side formwork 1. The formwork 1 is fixed to the fixing square tubes using wood screws or special connectors.

[0043] Place the horizontal edge of the L-shaped custom bracket 6 tightly against the main keel 3 or related lower support structure. Align the vertical edge of the bracket 6 with the outer side of the already installed vertical fixed square tube 5. Use bolts or other fasteners to securely connect the vertical edge of the bracket 6 to the vertical fixed square tube 5. At this point, the beam side formwork 1, the vertical fixed square tube 5, and the L-shaped bracket 6 together form a stable triangular support structure, effectively resisting the lateral pressure generated during concrete pouring and completely replacing the function of traditional tie rods. Repeat the installation of the bracket 6 at intervals along the length of the concrete beam until the entire beam side formwork is reinforced.

[0044] Once the concrete strength reaches the demolding strength specified in the standard, dismantle the formwork in the reverse order of installation. First, loosen and remove the connecting parts between the L-shaped bracket 6 and the vertical fixed square tube 5, remove all brackets 6, then remove the longitudinal fixed square tube 4 and the vertical fixed square tube 5, then remove the beam side formwork 1 and the beam bottom formwork 1, and finally, remove the secondary keel 2, the main keel 3 and the lower disc buckle support system in sequence.

Matters not covered in this utility model are common knowledge to those skilled in the art.
