Description

Technical Field

[0001] The utility model relates to the technical field of template reinforcement, in particular to a concrete template construction reinforcement device. Background Art

[0002] During the pouring of concrete formwork, the fluidity and deadweight of concrete will generate a large lateral pressure on the formwork. If the formwork is not effectively reinforced, it will easily deform, resulting in dimensional deviation of the concrete structure. In the process of reinforcing the formwork, square column buckles are needed.

[0003] At present, the existing main square column buckles are formed by four sets of elbow clamps to form an embracing structure and fixed by four sets of fixing pins, so that the connecting frame can be installed on the side of the square column formwork. During the construction process, there may be various vibration sources, such as the vibration of the vibrating rod and the operation vibration of the construction equipment. These vibrations will be transmitted to the square column buckles, causing the fixing pins to be subjected to continuous vibration. Over time, the fixing pins may loosen and move, which will cause the concrete to deform during the pouring process. Therefore, we propose a concrete formwork construction reinforcement device to solve the above problem. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5 A concrete formwork construction reinforcement device includes an elbow clamp 1, which is provided with four groups of elbow clamps 1, and the ends of the four groups of elbow clamps 1 are respectively inserted with fixing pins 2. A cavity is provided inside the fixing pin 2, and the inner wall of the cavity is vertically connected with a threaded rod 3 through a bearing. The outer side of the threaded rod 3 is sleeved with a threaded sleeve 4, and the side of the threaded sleeve 4 is connected to the support block 5 through a connecting rod. A movable groove adapted to the connecting rod is provided inside the fixing pin 2. By opening the movable groove, the vertical movement requirements of the connecting rod and the support block 5 can be met. The inner wall of the support block 5 is connected with a rotating shaft 6 through a bearing, and the outer side of the rotating shaft 6 is sleeved with a limiting plate 7. The rotation requirements of the limiting plate 7 can be met by the mutual cooperation of the rotating shaft 6 and the support block 5.

[0024] Further, refer to Figure 1 and Figure 3 It can be seen that a protective pad 12 is connected to the outer side of the elbow clamp 1, and there are two groups of protective pads 12. When in use, the side wall of the elbow clamp 1 can be protected by the setting of two groups of protective pads 12, so as to effectively prevent the side wall of the elbow clamp 1 from being scratched during transfer, and at the same time effectively ensure the reliability of the elbow clamp 1 against the template.

[0025] Further, refer to Figure 3 It can be seen that a protective cover 13 is glued on the top of the fixing pin 2, and the protective cover 13 is set as a U-shaped structure. When in use, the protective cover 13 set with the U-shaped structure can achieve covering protection for the top of the fixing pin 2, so that the staff can use tools to hammer the fixing pin 2 into the reserved groove opened inside the elbow clamp 1.

[0026] Further, refer to Figure 4 and Figure 5 It can be seen that the side of the support block 5 is symmetrically connected with a slider 8, and the interior of the fixing pin 2 is provided with a sliding groove adapted to the slider 8. During use, the mutual cooperation between the slider 8 and the sliding groove can effectively ensure the stability of the support block 5 during vertical movement.

[0027] Further, refer to Figure 5 It can be seen that the inner wall of the support block 5 is symmetrically connected to the fixing ring 9, and the upper and lower ends of the fixing ring 9 are symmetrically provided with slots, the inner wall of the slot is vertically connected to the connecting spring 10, and the other end of the connecting spring 10 is connected to the arc rod 11, and the arc rod 11 passes through the fixing ring 9 and extends to the rotating shaft 6. The interior of the rotating shaft 6 is provided with a limiting groove adapted to the fixing ring 9. When in use, the arc rod 11 set by the arc structure and combined with the setting of the connecting spring 10 can achieve preliminary limiting of the limiting plate 7, thereby effectively preventing the limiting plate 7 from rotating easily during the rotation process.

[0028] Further, refer to Figure 3 It can be seen that the top of the threaded rod 3 is equidistantly connected to a rotating plate 14, and a rectangular groove is provided above the fixing pin 2. By opening the rectangular groove and setting the rotating plate 14, the staff can quickly rotate the threaded rod 3 without affecting the staff's hammering of the fixing pin 2.

[0029] Further, refer to Figure 2 It can be seen that there are two groups of limit plates 7, and grooves are opened inside the two groups of limit plates 7. There are also two groups of parts such as support blocks 5 and sliders 8. By setting up two groups of limit plates 7, the limiting effect of the fixing pin 2 can be improved. By opening the grooves, it is convenient for the staff to rotate the limit plates 7.

[0030] Working principle: When the utility model is in use, the staff can first surround the four groups of elbow clamps 1 around the outside of the column template, and then insert each group of fixing pins 2 into the reserved groove inside the elbow clamp 1 to fix the elbow clamp 1 to the outside of the column template. After the fixing pins 2 are inserted, the staff can rotate the rotating plate 14, thereby driving the threaded rod 3 to rotate at the same time, so that the threaded sleeve 4 is threadedly matched with it, thereby moving the two groups of support blocks 5 and the limit plate 7 to the bottom of the elbow clamp 1. After the movement is completed, the staff can detent the two groups of limit plates 7 to rotate under force. During the rotation of the limit plates 7, the arc rod 1 set in the arc structure 1 is able to be forced to squeeze the connecting spring 10 and deform. When the limit plate 7 is rotated ninety degrees, the support block 5 is able to limit the limit plate 7. Then the staff can rotate the rotating plate 14 in the opposite direction, so that the two groups of limit plates 7 are able to be forced to abut against the lower side of the elbow clamping plate 1, so as to limit the inserted fixing pin 2. When the staff needs to pull out the fixing pin 2, the staff can rotate the fixing pin 2 to make the two groups of limit plates 7 be forced to move away from the elbow clamping plate 1, and then the staff can push the two groups of limit plates 7 to be stored in the side wall of the fixing pin 2. At this time, the staff can pull out the fixing pin 2. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated on.
