Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, in particular to a concrete support corner formwork reinforcement device. Background Art
[0002] Deep foundation pit engineering includes foundation pit support construction and earth excavation. The foundation pit support system is a temporary structure. In the construction of large multi-story basements or foundation pits with large excavation depths, there are often multiple horizontal reinforced concrete supports. Due to the irregular shape of the foundation pit, the horizontal supports are arranged in a non-linear and right-angled form at the intersection of the horizontal supports, the edges of the foundation pit, and the corners of the foundation pit. During construction, the support mold expansion and cracking are often caused by unreasonable template settings at the corners and inadequate reinforcement, which seriously affects the safety of the structure. Summary of the invention
[0003] The purpose of the utility model is to overcome the above defects and provide a concrete support corner formwork reinforcement device.
[0004] The technical solution adopted by the utility model is as follows: a concrete support corner formwork reinforcement device comprises a pair of fixing bars, which are respectively fixedly connected to the back ribs of the formwork, the ends of the fixing bars are provided with a plurality of pin holes, and the pin shafts pass through the overlapping pin holes to connect the pair of fixing bars in an X shape; and also comprises a reinforcement bar, the two ends of the reinforcement bar are provided with pins, which are inserted into the pin holes of the fixing bar, so as to connect the parts of the two fixing bars away from the back ribs.
[0005] The fixing strip is a channel steel, the bottom surface of which is U-shaped and fits the template, and has pin holes on both sides. The bottom surface of at least one fixing strip is provided with a through hole for another fixing strip to pass through.
[0006] The pair of fixing bars of the utility model can adjust the angle to adapt to different concrete support corners; the reinforcement bar pulls the pair of fixing bars to form a stable triangular structure, which can complete the reinforcement of the template at the corner, thereby avoiding the above-mentioned horizontal support construction quality problems caused by inadequate template construction.

[0009] Figure 5 It is a reference diagram of the usage status of another embodiment. DETAILED DESCRIPTION
[0010] See attached Figure 1 , 2. This embodiment includes fixing bars 1 and 2, both of which are channel steels with U-shaped cross-sections, with a cross-section height of 40 mm, a leg width of 40 mm, and a thickness of 5 mm. A through hole 21 is provided on the bottom surface of the fixing bar 2, which is 60 mm long and 40 mm wide, so that the fixing bar 1 can pass through the through hole, and the two fixing bars intersect. The U-shaped legs of the two fixing bars are provided with pin holes 3 with a diameter of 20 mm every 100 mm along the length direction. At the intersection of the two fixing bars, the pin shaft 4 passes through the overlapping pin holes of the two fixing bars to connect the two fixing bars into an X shape. There are pins 51 at each end of the reinforcement bar 5, which are inserted into the pin holes at the ends of the two fixing bars, so as to fix the angle between the two fixing bars 1 and 2.
[0011] See attached Figure 3 , 4 Two templates 00 form a corner. When the present embodiment is used for reinforcement, the angle of the X-shape formed by the two fixing strips is adjusted, and the two fixing strips are inserted into the back ribs 10 on the back of the two templates. After they are fitted in place, the reinforcing strips 5 are inserted. The above operation is then repeated in multiple back ribs of different heights, so that multiple reinforcement devices can reinforce the template forming the corner.
[0012] See attached Figure 5 . With attached Figure 4 In comparison, the others are the same, the difference is that an obtuse angle is formed between the two templates here, and this embodiment can still be used in the same way to reinforce the template.
