Description

Technical Field

[0001] This patent relates to the field of support technology, specifically a positionable concrete steel bar support. Background Art

[0002] Four tunnels need to be set up at the four corners of the wall in the building for placing steel bars and pouring concrete inside. Brackets need to be set up in the tunnels to support the steel bars. In order to increase the positioning effect of the steel bars, the diameter of the positioning holes on the bracket plate matches the diameter of the steel bars. However, when the steel bars are inserted, there will be greater friction between the side walls of the steel bars and the inner walls of the positioning holes, which makes it inconvenient to insert the steel bars and reduces the installation efficiency. For this reason, we propose a positionable concrete steel bar bracket. Utility Model Content

[0025] The pouring holes 8 are used for pouring concrete into the construction tunnel.

[0026] A connecting square tube 10 is provided between the upper bracket plate 2, the middle bracket plate 3 and the lower bracket plate 4. The upper and lower ends of the upper connecting square tube 10 are respectively fixedly installed on the upper bracket plate 2 and the middle bracket plate 3, and the upper and lower ends of the lower connecting square tube 10 are respectively fixedly installed on the middle bracket plate 3 and the lower bracket plate 4.

[0027] The connecting square tube 10 is used to increase the connection effect between the upper support plate 2, the middle support plate 3 and the lower support plate 4.

[0028] Specifically, through holes 11 are provided on four sides of the side wall connecting the square tube 10 .

[0029] Specifically, the size of the connecting square tube 10 is smaller than the sizes of the upper support plate 2 , the middle support plate 3 and the lower support plate 4 .

[0030] The concrete entering the tunnel will enter between the outer wall of the connecting square tube 10 and the inner wall of the tunnel through the through hole 11, thereby increasing the connectivity between the connecting square tube 10 and the tunnel.

[0031] Specifically, the upper support plate 2, the middle support plate 3 and the lower support plate 4 all include an upper plate body 12 and a lower plate body 13, and the bottom of the upper plate body 12 and the top of the lower plate body 13 are relatively fixedly installed.

[0032] By dividing the bracket plate into an upper plate body 12 and a lower plate body 13 , the mounting groove 6 can be divided into two parts, which is convenient for opening the mounting groove 6 in the early stage and for installing the limiting wheel 7 in the mounting groove 6 .

[0033] Specifically, the upper plate body 12 and the lower plate body 13 are both provided with mounting holes 14, and the number of the mounting holes 14 is four. The mounting holes 14 on the upper plate body 12 and the lower plate body 13 are connected to each other. Mounting bolts 15 are provided in the mounting holes 14, and the bottom ends of the mounting bolts 15 pass through the mounting holes 14 and are screwed with nuts 16.

[0034] Specifically, a circular groove 17 is provided on the top of the upper plate body 12 and the bottom of the lower plate body 13 . The circular groove 17 is communicated with the mounting hole 14 . The top end of the mounting bolt 15 and the nut 16 are located in the circular groove 17 .

[0035] The circular groove 17 is provided to accommodate the top end of the mounting bolt 15 and the nut 16, thereby increasing the flatness of the top of the upper plate 12 and the bottom of the lower plate 13, and facilitating stacking of multiple bracket plates during early bracket plate transportation.

[0036] Specifically, the top end of the mounting bolt 15 and the side wall of the nut 16 do not contact the inner side wall of the circular groove 17 .

[0037] Concrete can enter the circular groove 17 to increase the fixity of the mounting bolts 15 and nuts 16.

[0038] Working principle: install two connecting square tubes 10 between the upper bracket plate 2, the middle bracket plate 3 and the lower bracket plate 4, and then place the whole structure in the construction tunnel (they can also be placed separately when the construction range is large), insert the steel bar 9 into the square hole 5, and during the downward movement of the steel bar 9, the side wall of the steel bar 9 rolls in contact with the wheel body of the limiting wheel 7, which facilitates the downward movement and insertion of the steel bar 9. After the steel bar 9 is fully inserted, pour concrete into the tunnel through the pouring hole 8.
