Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a steel reinforcement fixing device for building structures. Background Technology
[0002] In the construction process, the accurate fixing of steel bars is a key step in ensuring the stability and safety of the building structure.
[0003] Currently, existing methods of fixing reinforcing bars have many problems. For example, some existing reinforcing bar fixing devices require construction workers to perform cumbersome steps to fix and loosen the reinforcing bars, which not only increases construction time costs but also requires a high level of skill from the workers, resulting in low construction efficiency. Some traditional fixing devices are difficult to accurately position the reinforcing bars, and in subsequent construction processes such as concrete pouring, the reinforcing bars are prone to displacement, which can seriously affect the quality and stability of the building structure and increase structural safety hazards. Different specifications and shapes of reinforcing bars are widely used in building construction, but most existing fixing devices cannot flexibly adapt to multiple types of reinforcing bars. Construction units may need to prepare multiple fixing devices, which undoubtedly increases construction costs and management difficulty. Some reinforcing bar fixing devices are heavy and lack a structural design that facilitates transportation, making them difficult to move on the construction site. At the same time, their connection methods with the construction surface or other fixing structures are complex, and the installation process is time-consuming and labor-intensive, which is not conducive to the rapid progress of construction. The friction between traditional fixing devices and reinforcing bars is insufficient, making it difficult to effectively prevent the reinforcing bars from shifting during the fixing process, thereby affecting the quality of the entire building structure. Furthermore, some devices lack damping structures at rotating parts, resulting in uneven rotation and making it difficult to precisely control the clamping force, thus affecting the fixing effect.
[0004] Therefore, it is necessary to design a steel reinforcement fixing device for building structures to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to provide a steel reinforcement fixing device for building structures to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A steel reinforcement fixing device for building structures includes an upper clamping ring, a lower fixing ring, and a steel reinforcement limiting structure located on the upper clamping ring and the lower fixing ring. The upper clamping ring and the lower fixing ring are rotatably connected by a connecting shaft. The connecting shaft is arranged laterally and passes through the corresponding ears of the upper clamping ring and the lower fixing ring, so that the upper clamping ring can open and close relative to the lower fixing ring with the connecting shaft as the axis. Multiple sleeves are arranged around the outer side of the upper clamping ring and the lower fixing ring. A lever is connected to the side of the upper clamping ring away from the sleeves by a fixing pin. The lever is rotatably connected to the fixing ring with the connecting shaft as the axis. The other end of the upper clamping ring and the lower fixing ring is fixedly connected by a locking pin. When the upper clamping ring and the lower fixing ring clamp the steel reinforcement, the locking pin can be inserted into the corresponding pin hole of the upper clamping ring and the lower fixing ring to prevent the upper clamping ring from rotating accidentally. A pull ring is also fixedly connected to the bottom of the lower fixing ring. The pull ring has a notch inside.
[0008] As a preferred embodiment of this utility model, the rebar limiting structure includes a first connecting sleeve and a second connecting sleeve that are slidably connected inside multiple sleeves. The first connecting sleeve and the second connecting sleeve are coaxially arranged. A limiting post is fixedly fixed inside the first connecting sleeve and the second connecting sleeve. An adjusting handle is also fixedly connected to one side of the limiting post. The first connecting sleeve and the second connecting sleeve are locked and fixed to the sleeves by limiting screws and locking screws, respectively.
[0009] As a preferred embodiment of this utility model, the gripping part of the toggle handle is provided with a pin hole, and the fixing pin can be inserted into the pin hole. When the toggle handle is adjusted to a suitable position, the toggle handle and the upper clamping ring can be fixed by inserting the fixing pin.
[0010] In a preferred embodiment of this utility model, the upper clamping ring and the lower fixing ring are symmetrical semi-circular ring structures, and an annular cavity is provided between the upper clamping ring and the lower fixing ring. The width of the annular cavity is greater than the diameter of the reinforcing bar, which facilitates the placement of the reinforcing bar inside the annular cavity.
[0011] As a preferred embodiment of this utility model, the end surface of the limiting post is provided with anti-slip texture. The anti-slip texture is distributed in an irregular shape such as a grid or wave, which increases the friction with the surface of the reinforcing bar and prevents the reinforcing bar from shifting during the fixing process.
[0012] As a preferred embodiment of this utility model, a damping structure is provided at the connecting shaft. The damping structure includes a damping sleeve and a damping pad. The damping sleeve is sleeved on the connecting shaft and located between the ears of the upper clamping ring and the lower fixing ring. The damping pad is disposed on the contact surface of the ears of the upper clamping ring and the lower fixing ring. The damping structure increases the resistance when the upper clamping ring rotates, making the rotation of the upper clamping ring more stable and facilitating precise adjustment of the clamping force.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This utility model, through the provision of a rebar fixing device for building structures, achieves the following effects: 1. By rotating the handle, the upper clamping ring can be easily opened and closed relative to the lower fixing ring, quickly completing the fixing and loosening of the rebar, greatly improving construction efficiency and reducing construction time and labor costs. Furthermore, the handle is fixed in a suitable position by a fixing pin to adjust the angle of the handle; 2. The limiting posts in the rebar limiting structure can accurately limit the rebar, ensuring that the rebar will not shift during construction, effectively guaranteeing the quality and stability of the building structure; 3. The first and second connecting sleeves in the rebar limiting structure can be adjusted via limiting screws, locking screws, and adjusting handles, flexibly changing the position and spacing of the limiting posts to adapt to rebars of different specifications and shapes, expanding the applicability of the device, and reducing construction costs and management difficulty; 4. The pull ring at the bottom of the lower fixing ring facilitates gripping by construction personnel, improving the device's mobility on the construction site; 5. The anti-slip texture on the end surface of the limiting post increases the friction with the rebar surface, effectively preventing rebar displacement during fixing. The damping structure at the connecting shaft increases the resistance when the upper clamping ring rotates, making the rotation smoother and allowing construction personnel to accurately adjust the clamping force, further improving the effect of steel bar fixing and the stability of the device.

[0025] For examples, please refer to Figure 1-5 This utility model provides a technical solution:
[0026] A steel reinforcement fixing device for building structures includes an upper clamping ring 1, a lower fixing ring 2, and a steel reinforcement limiting structure 3 located on the upper clamping ring 1 and the lower fixing ring 2. The upper clamping ring 1 and the lower fixing ring 2 are rotatably connected by a connecting shaft 4. The connecting shaft 4 is arranged laterally and passes through the corresponding ears of the upper clamping ring 1 and the lower fixing ring 2, so that the upper clamping ring 1 can open and close relative to the lower fixing ring 2 with the connecting shaft 4 as the axis. Multiple sleeves 5 are arranged around the outer sides of the upper clamping ring 1 and the lower fixing ring 2. A lever handle 7 is connected to the side of the upper clamping ring 1 away from the sleeves 5 through a fixing pin 6. The lever handle 7 is rotatably connected to the lower fixing ring 2 with the connecting shaft 4 as the axis. The other end is fixedly connected by a locking pin 8. When the upper clamping ring 1 and the lower fixing ring 2 clamp the steel bar, the locking pin 8 can be inserted into the corresponding pin holes of the upper clamping ring 1 and the lower fixing ring 2 to prevent the upper clamping ring 1 from rotating accidentally. The bottom of the lower fixing ring 2 is also fixedly connected to a pull ring 9, and the pull ring 9 has a notch 10 inside. The construction worker holds the lever 7 and rotates the upper clamping ring 1 with the connecting shaft 4 as the axis, so that it opens relative to the lower fixing ring 2. The steel bar is placed in the annular cavity between the upper clamping ring 1 and the lower fixing ring 2. Then, the lever 7 is rotated in the opposite direction to drive the upper clamping ring 1 to close. When it is clamped in place, the locking pin 8 is inserted into the corresponding pin holes of the upper clamping ring 1 and the lower fixing ring 2 to prevent the upper clamping ring 1 from rotating accidentally.
[0027] Specifically, the rebar limiting structure 3 includes a first connecting sleeve 31 and a second connecting sleeve 32 slidably connected inside multiple sleeves 5. The first and second connecting sleeves are coaxially arranged, and a limiting post 33 is fixedly fixed through the inside of the first connecting sleeve 31 and the second connecting sleeve 32. An adjusting handle 34 is also fixedly connected to one side of the limiting post 33. The first connecting sleeve 31 and the second connecting sleeve 32 are locked to the sleeves 5 by limiting screws 35 and locking screws 36, respectively. According to the specifications of the rebar, the position of the first connecting sleeve 31 and the second connecting sleeve 32 within the sleeves 5 is adjusted by adjusting the handle 34. During adjustment, first loosen the limiting screws 35 and the locking screws 36, move the first connecting sleeve 31 and the second connecting sleeve 32 to place the limiting post 33 in a suitable position, and then tighten the limiting screws 35 and the locking screws 36 to fix it. The rebar is placed between the limiting posts 33, and the limiting posts 33 limit the rebar. The rebar limiting structure 3 is flexibly adjustable and can adapt to rebars of different specifications, improving the versatility of the device. The limiting column 33 plays a precise limiting role for the reinforcing bars, preventing them from shifting during the fixing process and ensuring the quality of the building structure.
[0028] Specifically, the gripping part of the lever handle 7 is provided with a pin hole, into which the fixing pin 6 can be inserted. After the lever handle 7 is adjusted to a suitable position, the lever handle 7 and the upper clamping ring 1 can be fixed by inserting the fixing pin 6. After adjusting the position of the upper clamping ring 1 with the lever handle 7, the fixing pin 6 is inserted into the pin hole of the gripping part of the lever handle 7 to fix the lever handle 7 and the upper clamping ring 1. This prevents the lever handle 7 from rotating accidentally and ensures that the upper clamping ring 1 always maintains a compressed state on the reinforcing steel during construction, thus improving the safety and stability of the device.
[0029] Specifically, the upper clamping ring 1 and the lower fixing ring 2 are symmetrical semi-circular ring structures, and a circular cavity is provided between the upper clamping ring 1 and the lower fixing ring 2. The width of the circular cavity is greater than the diameter of the reinforcing bar, so that the reinforcing bar can be placed inside the circular cavity.
[0030] Specifically, the end surface of the limiting post 33 is provided with anti-slip texture. The anti-slip texture is distributed in an irregular shape such as a grid or wave, which increases the friction with the surface of the reinforcing bar and prevents the reinforcing bar from shifting during the fixing process.
[0031] Specifically, a damping structure is provided at the connecting shaft 4. The damping structure includes a damping sleeve and a damping pad. The damping sleeve is fitted onto the connecting shaft 4 and is located between the ears of the upper clamping ring 1 and the lower fixing ring 2. The damping pad is set on the contact surface of the ears of the upper clamping ring 1 and the lower fixing ring 2. The damping structure increases the resistance when the upper clamping ring 1 rotates, making the rotation of the upper clamping ring 1 more stable and facilitating precise adjustment of the clamping force.
[0032] The working process of this utility model is as follows: When using the steel bar fixing device for building structure, first hold the lever 7 and rotate the upper clamping ring 1 around the connecting shaft 4 to open it relative to the lower fixing ring 2. Insert the steel bar into the annular cavity, and then rotate the lever 7 in the opposite direction to close the upper clamping ring 1 and initially fix the steel bar. After it is clamped in place, insert the locking pin 8 into the corresponding pin hole of the upper clamping ring 1 and the lower fixing ring 2 to prevent the upper clamping ring 1 from rotating accidentally. Then, adjust the steel bar limiting structure 3 according to the steel bar specifications. By adjusting the lever 34, loosen the limiting screw 35 and the locking screw 36, slide the first connecting sleeve 31 and the second connecting sleeve 32 in the sleeve 5, adjust the spacing and angle of the limiting post 33 to fit the steel bar, and then tighten the limiting screw 35 and the locking screw 36 to fix it.
[0033] Although embodiments of the present invention have been shown and described, 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.
