Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction, and specifically relates to a special-shaped column formwork supplementing and reinforcing device. BACKGROUND

[0002] In the field of building engineering, special-shaped columns are widely used as a special structural component. Compared with traditional rectangular columns, special-shaped columns have unique spatial adaptability and can meet the design requirements of building diversification. For example, in residential buildings, commercial complexes and other buildings, special-shaped columns can be ingeniously arranged in irregular building corners, effectively utilizing space and avoiding the appearance of protruding column bodies in the room, which affects the aesthetics and use function.

[0003] However, the construction of special-shaped columns faces many difficulties, among which the formwork supplementing and reinforcing link is particularly critical. Due to the complex shape of special-shaped columns, common L-shaped, cross-shaped and other shapes cannot use standardized fixing modes for formwork installation like rectangular columns. Traditional reinforcing methods usually customize special formworks and reinforcing devices for specific special-shaped column shapes, which not only consumes a lot of time and labor costs for design and production, but also has extremely poor versatility. Once different sizes or slightly changed shapes of special-shaped columns are encountered, the existing reinforcing devices are often difficult to apply, and have to be re-produced, which seriously affects the construction progress.

[0004] In addition, during the concrete pouring process, the irregular shape of the special-shaped column causes uneven lateral pressure on the formwork, which easily leads to formwork deformation, grout leakage and other difficult conditions. If the reinforcing device cannot effectively adapt to such pressure changes, it is easy to cause formwork deformation, grout leakage and other problems, thereby affecting the forming quality of the special-shaped column, and causing defects such as honeycomb pitting on the concrete surface and size deviation, with high repair costs in the later period.

[0026] As Figure 1 And Figure 2 As shown in the drawings, the end top position of two swing arm parts 12 is symmetrically hinged with first reinforcing square tube 3, and the same side two first reinforcing square tubes 3 are connected through being inserted in first positioning square tube 4, the end bottom position of two swing arm parts 12 is symmetrically hinged with second reinforcing square tube 5, and the same side two second reinforcing square tubes 5 are positioned through being inserted in second positioning square tube 6, the cross section and external shape of first reinforcing square tube 3 and second reinforcing square tube 5 are all same, and a plurality of first reinforcing square tubes 3, first positioning square tubes 4, second reinforcing square tubes 5 and second positioning square tubes 6 are combined into square make-up reinforcing module;

[0027] Specifically, when the adjusting screw rod 7 is rotated, the two inner beam rods 11 will drive the four swing arm parts 12 to move together, the angle between the two ends of the four swing arm parts 12 relative to the two inner beam rods 11 changes, and the four swing arm parts 12 drive the first reinforcing square tube 3 and the second reinforcing square tube 5 to move, the outer leakage of the first reinforcing square tube 3 relative to the first positioning square tube 4 (i.e. the length between the two first reinforcing square tubes 3 and a single first positioning square tube 4) and the outer leakage of the second reinforcing square tube 5 relative to the second positioning square tube 6 change, the size of the square supplement and reinforcement module in the above changes, so that Figure 2 For example, the cross-shaped special-shaped column in the above, the required supplement and reinforcement area is four, after adjusting the square supplement and reinforcement module to the required supplement size of the cross-shaped special-shaped column, placing several utility models in the corresponding area, then overall external support is carried out on the cross-shaped special-shaped column, so that the outer formwork support of the special-shaped column is in a square state, and the square structure has better symmetry and stability.

[0030] Referring to Figures 1-4 The inner beam rod 11 is provided with a through hole 112, and the two through holes 112 on the same inner beam rod 11 are symmetrically distributed around the insertion hole axis. The two through holes 112 on the two inner beam rods 11 are inserted with a limiting rod 113, and the two limiting rods 113 can position the inner beam rod 11 relative to the adjusting screw rod 7 in the circumferential direction. When the adjusting screw rod 7 is rotated, it is not necessary to manually press and position the auxiliary inner support 2, but only to directly rotate the adjusting screw rod 7. The end of the adjusting screw rod 7 is generally hexagonal in cross section, which is convenient for rotating the adjusting screw rod 7 by a wrench.

[0031] The two end faces of the limiting rod 113 are provided with limiting bolts 114, and the limiting bolts 114 are detachable relative to the limiting rod 113.

The end of the outer connecting arm 124 is hinged with the first reinforcing square tube 3 and the second reinforcing square tube 5 respectively at the upper and lower ends. Before the size of the square missing reinforcing module is adjusted by the rotating adjusting threaded rod 7, the inner threaded branch pipe 123 can be rotated first to adjust the elongation relative to the outer threaded rod 122, so that the overall length of the swing arm part 12 can be changed, thereby further improving the adjustment range of the size of the square missing reinforcing module.

[0033] It should be noted that when the overall length of the swing arm part 12 is adjusted, the overall length of the swing arm part 12 at each position needs to be kept consistent.

[0034] Referring to Figures 1-4 The inner middle position of the adjusting threaded rod 7 is provided with an inner threaded through hole 72. Threaded jacks 73 are installed at the two ends of the inner threaded through hole 72. A round rod 74 is connected to the end of the threaded jack 73 through a rotary joint. A C-shaped plate 75 is welded to the end of the round rod 74. After the size positioning of the square missing reinforcing module is completed, the construction personnel can rotate the threaded jack 73 to make it protrude out of the inner threaded through hole 72 until the outer wall of the C-shaped plate 75 abuts against the inner wall of the second positioning square tube 6 to internally support the inner wall of the second positioning square tube 6 and increase the overall strength of the second positioning square tube 6, so that the second positioning square tube 6 is not easy to deform during use.

[0035] Further, the outer side of the limiting rod 113 is provided with a hanging plate 81. The end of the hanging plate 81 in contact with the limiting rod 113 is a circular arc surface. The other end of the hanging plate 81 is installed with a reinforcing threaded rod 82 through thread cooperation. The end of the reinforcing threaded rod 82 is connected with an abutting buckle 83 through a rotary joint. The inner side cross section of the abutting buckle 83 is the same as the cross section shape of the first positioning square tube 4. Similarly, after the size positioning of the square missing reinforcing module is completed, the construction personnel can place one end of the hanging plate 81 on the outer wall of the limiting rod 113 and then rotate the reinforcing threaded rod 82 to make the other end of the hanging plate 81 protrude out until the inner wall of the abutting buckle 83 abuts against the inner wall of the first positioning square tube 4 to internally support the inner wall of the first positioning square tube 4 and increase the overall strength of the first positioning square tube 4, so that the second positioning square tube 6 is not easy to deform during use.
