Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a single-sided concrete formwork reinforcement device. Background Technology

[0002] In the construction of exterior walls and edge beams in building engineering, single-sided formwork is a common construction scenario. However, single-sided formwork faces many challenging problems in practice, the most prominent being the difficulty of reinforcement. Because single-sided formwork lacks effective support and constraint on the opposite side, the formwork system is highly susceptible to displacement or deformation under lateral pressure during concrete pouring. This unstable formwork condition often leads to vertical deviations in the concrete structure exceeding the allowable range specified in the standards, resulting in a series of common quality problems such as uneven structural stress and appearance defects, seriously affecting the overall quality and durability of the building project. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a concrete single-sided formwork reinforcement device to solve the problem of concrete single-sided formwork reinforcement.

[0004] To solve the above-mentioned technical problems, this utility model provides a single-sided concrete formwork reinforcement device, including a pressure head set inside the formwork and a square timber set outside the formwork, a steel pipe set on one side of the square timber, a screw rod that movably connects the pressure head and passes through the formwork and the square timber, a U-shaped clip set on the screw rod on one side of the square timber, and a nut set outside the U-shaped clip, wherein the steel pipe is clamped between the U-shaped clip and the square timber.

[0005] In a preferred embodiment, an extension rod is provided on the side where the pressure head is connected to the screw. A first boss is provided on the outer circle of the end of the extension rod. A blind hole matching the diameter of the extension rod is provided at the corresponding position of the screw. A through groove matching the first boss is provided in the blind hole along the diameter of the screw. A communicating groove is provided at the bottom of the through groove.

[0006] In the preferred embodiment, the distance from the highest point of the first boss to the axis of the extension rod is less than the radius of the screw.

[0007] In a preferred embodiment, the length of the through groove is less than the depth of the blind hole, and a spring is provided between the extension rod and the bottom of the blind hole.

[0008] In the preferred embodiment, the groove is L-shaped.

[0009] In a preferred embodiment, a second boss is provided between the extension rod and the pressure head, and the diameter of the second boss is equal to that of the screw.

[0010] The beneficial effects of this utility model are: by tightening the nut, the nut generates pressure perpendicular to the screw, which in turn drives the mountain-shaped clamp, steel pipe, square timber and pressure head to clamp and fix the position of the template, making it convenient to pour concrete in the space enclosed by the template later. Furthermore, the screw can be recycled later through the detachable connection between the screw and the pressure head, achieving the purpose of reusing the screw. Attached Figure Description

[0016] Please see Figure 1-3 As shown, the present application provides a technical solution: a single-sided concrete formwork reinforcement device. To solve the above-mentioned technical problems, the present invention provides a single-sided concrete formwork reinforcement device, including a pressure head 11 disposed inside the formwork 101 and a square timber 12 disposed outside the formwork 101, a steel pipe 13 disposed on one side of the square timber 12, a screw 14 movably connecting the pressure head 11 and passing through the formwork 101 and the square timber 12, a U-shaped clip 15 disposed on the screw 14 on one side of the square timber 12, and a nut 19 disposed outside the U-shaped clip 15, wherein the steel pipe 13 is sandwiched between the U-shaped clip 15 and the square timber 12.

[0017] By tightening the nut 19, the nut 19 generates pressure in the direction perpendicular to the screw 14, which in turn drives the mountain-shaped clamp 15, steel pipe 13, square timber 12 and pressure head 11 to clamp and fix the position of the template 101, making it convenient to pour concrete into the space enclosed by the template 101 later.

[0018] In a preferred embodiment, an extension rod 16 is connected to the screw 14 on one side. A first boss 17 is provided on the outer circle of the end of the extension rod 16. A blind hole 141 matching the diameter of the extension rod 16 is provided at the corresponding position of the screw 14. A through groove 142 matching the first boss 17 is provided in the blind hole 141 along the diameter of the screw 14. A communicating groove 143 is provided at the bottom of the through groove 142.

[0019] Thus, the connection between the pressure head 11 and the screw 14 is as follows: align the first boss 17 with the through groove 142, align the extension rod 16 with the blind hole 141 on the screw 14, align the first boss 17 on the extension rod 16 with the through groove 142 on the screw 14, and then insert the extension rod 16 into the blind hole 141. When the first boss 17 contacts the bottom of the through groove 142, rotate it a certain angle to engage the first boss 17 into the groove 143. Because tightening the nut 19 generates an outward pulling force on the screw 14, the connection between the pressure head 11 and the screw 14 will not disengage, thus serving a connecting function. After the concrete pouring is completed, the operation can be reversed to remove the screw 14, allowing for its reuse.

[0020] In a preferred embodiment, the distance from the highest point of the first boss 17 to the axis of the extension rod 16 is less than the radius of the screw 14.

[0021] In this way, the first boss 17 does not protrude to the upper surface of the screw 14 in the diameter direction, so that opening a hole in the template 101 can satisfy the insertion and exit of the screw 14 and the extension rod 16.

[0022] In a preferred embodiment, the length of the through groove 142 is less than the depth of the blind hole 141, and a spring 18 is provided between the extension rod 16 and the bottom of the blind hole 141.

[0023] The purpose of setting the spring 18 is that when the first boss 17 is engaged in the groove 143, the spring 18 can provide a spreading force to the extension rod 16 and the screw 14, so that the extension rod 16 and the screw 14 can be connected together.

[0024] In the preferred embodiment, the groove 143 is L-shaped.

[0025] After the first boss 17 rotates into the groove 143, it can still be locked inside the groove 143. After the first boss 17 is installed in place, it needs to move in two directions to move into the through groove 142, so it is not easy to detach.

[0026] In a preferred embodiment, a second boss 21 is provided between the extension rod 16 and the pressure head 11, and the diameter of the second boss 21 is equal to that of the screw 14.

[0027] In this way, the second protrusion 21 can be inserted into the template 101, which can reduce the gap between the template 101 and the second protrusion 21. Firstly, it can improve the strength of the template 101, and the poured concrete is less likely to enter this gap.

[0028] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
