Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a concrete formwork support device. Background Technology

[0002] Concrete formwork support devices are auxiliary equipment specifically designed to support the formwork and reinforcing steel bars during concrete pouring. Their main function is to ensure the stability of the formwork system, preventing deformation or collapse during pouring, and also ensuring the reinforcing steel bars remain in the correct position, preventing displacement or deformation during pouring. This, in turn, guarantees the strength, stability, and construction quality of the concrete structure.

[0003] Current concrete formwork support systems primarily rely on wrapping the outside of the formwork to achieve stability. However, in practical applications, especially when vertically installing square steel bars onto concrete formwork, traditional support devices prove inadequate. They often fail to establish effective support contact directly with the formwork surface, instead applying almost all the tightening force to the square steel bars. This results in large open areas between the formwork and the support device, where insufficient support can lead to significantly inadequate tightening force. This insufficient support not only affects the quality of concrete forming but also poses potential safety hazards. Furthermore, traditional support devices face significant challenges with irregularly shaped formwork. Due to the diverse surface features of irregularly shaped formwork, standardized support methods are difficult to apply, easily leading to unstable support and insufficient tightening force. Summary of the Invention

[0004] The purpose of this utility model is to provide a concrete formwork support device to solve the problem mentioned in the background art of insufficient support capacity of existing support devices for concrete formwork with square steel installed on the surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete formwork support device, comprising two symmetrically arranged limiting plates, each with a strip groove in its center; two symmetrically arranged limiting studs, which movably penetrate the strip groove in the center of the limiting plate. During construction, the concrete formwork is supported by the "U"-shaped structure formed by the limiting plates and the limiting studs. Multiple sets of clamping components are provided within each limiting plate. Each set of clamping components includes: a fitting member disposed within the internal area formed by the limiting plates and the limiting studs; and a clamping member movably penetrating the strip groove in the center of the limiting plate, with one end located within the internal area of ​​the limiting plates and the limiting studs, and the other end located outside the limiting plates. The fitting member is installed at the end of the clamping member, and the clamping member drives the fitting member to move towards the internal area of ​​the limiting plates and the limiting studs, thereby clamping the concrete formwork inside the limiting plates and the limiting studs and improving the support capacity.

[0006] Preferably, the clamping component includes a screw rod that movably passes through the central slot of the limiting plate. An end plate is fitted at one end of the screw rod, which is in contact with the outer surface of the limiting plate. A locking nut is also screwed into one end of the screw rod, which abuts against the end plate. A spring is fitted in the middle of the screw rod. The other end of the screw rod is connected to the fitting component. One end of the spring abuts against the inner wall of the limiting plate, and the other end abuts against the fitting component. Through the clamping of the spring, the screw rod can be driven to move inward toward the limiting plate and the limiting stud, thereby driving the fitting component to abut against the concrete formwork, thus achieving clamping. At the same time, since the screw rod can move within the slot, it can adjust its position according to the position of the square steel on the concrete formwork. When the screw rod moves, the locking nut will move synchronously and press the end plate against the limiting plate, thereby achieving a limiting connection between the screw rod and the limiting plate and preventing separation between the two.

[0007] Preferably, the bonding component includes a clamping plate fixed to the other end of the screw, and an arc-shaped block bonded to the end face of the clamping plate. The arc-shaped block is positioned towards the inner area of ​​the limiting plate and the limiting stud, and the middle of the arc-shaped block is raised. During the clamping of the concrete formwork, the arc-shaped block can better clamp onto the concrete formwork through deformation. This structure is also applicable to irregularly shaped concrete formwork and has a better clamping effect than that of a flat surface.

[0008] Preferably, a placement groove is provided in the middle of the inner side of the limiting plate. The depth of the placement groove is equal to the total thickness of the arc-shaped block, the abutment plate, and the spring compressed to its minimum length. When the surface of the concrete template is a flat plane, the arc-shaped block and the abutment plate are moved into the placement groove for placement to avoid protrusion and affecting normal support.

[0009] Preferably, both ends of the limiting stud are fitted with abutment plates, and nuts are screwed into both ends of the limiting stud. The nuts fit against the abutment plates, and the limiting plates are supported by the threads of the nuts and the limiting stud.

[0010] Preferably, the surface of the abutment is provided with an oil groove, the horizontal projection of which passes through the area where the limiting stud and nut are connected. In actual use, lubricating oil is poured into the oil groove to lubricate the connection between the limiting stud and nut, making it easy to open.

[0011] Preferably, the arc-shaped block and the abutment plate have equal longitudinal sections, and their widths are equal to the thickness of the limiting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By adding a clamping component to the middle of the limiting plate through the design of this utility model, the supporting device can be flexibly adjusted according to the specific position of the square steel installed on the surface of the concrete module during actual construction, thereby ensuring that the clamping component can fit tightly with the concrete template. This design not only effectively solves the problem of large gaps that may exist between the concrete template and the limiting plate, but also significantly improves the clamping force of the supporting device on the template. This not only improves the stability and safety during construction, but also ensures the quality of concrete molding. In addition, this design is also applicable to the support of irregular templates, further expanding its application range and bringing greater convenience to construction work.

[0021] 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.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a concrete formwork support device, including...

[0023] Two symmetrically arranged limiting plates 100, each with a strip groove formed in the middle;

[0024] Two symmetrically arranged limiting studs 200 are provided, and the limiting studs 200 move through the strip groove in the middle of the limiting plate 100. During construction, the concrete formwork is supported by the "U"-shaped structure formed by the limiting plate 100 and the limiting studs 200.

[0025] Multiple sets of clamping components are provided within each limiting plate 100, and each set of clamping components includes:

[0026] The fitting component is located within the internal area formed by the limiting plate 100 and the limiting stud 200;

[0027] The clamping member is movable through the strip groove in the middle of the limiting plate 100, with one end located inside the limiting plate 100 and the limiting stud 200, and the other end located outside the limiting plate 100. The fitting member is installed at the end of the clamping member. The clamping member drives the fitting member to move towards the inner area of ​​the limiting plate 100 and the limiting stud 200, thereby clamping the concrete formwork inside the limiting plate 100 and the limiting stud 200 and improving the support capacity.

[0028] In this embodiment, preferably, the clamping member includes a screw 300 that movably passes through the central slot of the limiting plate 100. An end plate 301 is fitted onto one end of the screw 300, and this end plate 301 is in contact with the outer surface of the limiting plate 100. A locking nut 302 is also screwed into one end of the screw 300, and this locking nut 302 abuts against the end plate 301. A spring 304 is fitted onto the middle of the screw 300. The other end of the screw 300 is connected to the fitting member. One end of the spring 304 abuts against the inner wall of the limiting plate 100, and the other end abuts against the fitting member. The spring 304... The tightening of the screw 300 causes it to move inward toward the limiting plate 100 and the limiting stud 200, thereby causing the fitting part to press against the concrete formwork. At the same time, since the screw 300 can move within the slot, it can adjust its position according to the position of the square steel on the concrete formwork. When the screw 300 moves, the locking nut 302 moves synchronously and presses the end plate 301 against the limiting plate 100, thereby limiting the connection between the screw 300 and the limiting plate 100 and preventing them from separating.

[0029] In this embodiment, preferably, the fitting component includes a clamping plate 305 fixed to the other end of the screw 300, and an arc-shaped block 303 bonded to the end face of the clamping plate 305. The arc-shaped block 303 is disposed facing the inner area of ​​the limiting plate 100 and the limiting stud 200, and the middle part of the arc-shaped block 303 is raised. In clamping the concrete template, the arc-shaped block 303 can better clamp onto the concrete template through deformation. This structure is also applicable to irregularly shaped concrete templates and has a better clamping effect than flat clamping.

[0030] In this embodiment, preferably, a placement groove 100a is also provided in the middle of the inner side of the limiting plate 100. The depth of the placement groove 100a is equal to the total thickness of the arc block 303, the abutment plate 305, and the spring 304 compressed to its minimum length. When the surface of the concrete template is a flat plane, the arc block 303 and the abutment plate 305 move into the placement groove 100a for placement to avoid protrusion affecting normal support.

[0031] In this embodiment, preferably, both ends of the limiting stud 200 are fitted with abutment plates 201, and nuts are screwed into both ends of the limiting stud 200. The nuts fit against the abutment plates 201, and the limiting plate 100 and the concrete formwork are supported by tightening the nuts with the threads of the limiting stud 200.

[0032] In this embodiment, preferably, an oil groove 201a is provided on the surface of the abutment plate 201. The horizontal projection of the oil groove 201a passes through the area where the limiting stud 200 and the nut are connected. In actual use, lubricating oil is poured into the oil groove 201a to lubricate the connection between the limiting stud 200 and the nut, making it easy to open.

[0033] In this embodiment, preferably, the longitudinal sections of the arc-shaped block 303 and the abutment plate 305 are equal, and the width of both is equal to the thickness of the limiting plate 100.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
