Abstract
Description
Technical Field
[0001] The utility model belongs to the field of building structures, and in particular relates to a loss-reducing self-fine-tuning hanging column structure under a beam. Background Art
[0002] Reinforced concrete beams are beams made of reinforced concrete. Reinforced concrete beams can be made into independent beams, or they can be made into beam-slab floor with reinforced concrete slabs, or they can be made into single-layer or multi-layer frames with reinforced concrete columns. When installing the lower hanging column on the concrete beam, the existing concrete beam lower hanging column has the following disadvantages:
[0003] When installing the hanging column under the concrete beam, it is necessary to drill holes at the bottom of the concrete beam. The problems with this operation method are mainly concentrated in three points:
[0004] First point: Drilling holes at the bottom can easily damage the steel bars at the bottom of the concrete beam;
[0005] Second point: When fixing, because the hole is vertically downward, the chemical agent cannot reach the upper part of the hole, resulting in an unreliable fixing method;
[0006] The third point: The connection between the U-shaped bracket and the lower hanger is connected by welding. When subjected to force or vibration, the lower hanger will pull the concrete beam downward, causing the concrete beam to crack.
[0007] Second, a semi-wrapped U-shaped bracket is used for fixing, which can avoid damage to the steel bars inside the concrete beam when drilling. However, when subjected to force or vibration, the force cannot be buffered, resulting in easy breakage at the connection between the lower suspension rod and the U-shaped bracket.
[0008] 3. The lower hanging rod and the U-shaped bracket cannot be adjusted during installation, and the length of the lower hanging rod cannot be controlled, resulting in the need to customize the lower hanging rod, or requiring secondary operations such as on-site cutting. The requirements for on-site temporary cutting and other related operations are high, and improper operation will result in waste. Summary of the invention

[0048] As Figure 1 shown, in this specific embodiment, a wrapping method is adopted for installation with the concrete beam 8.

The fixing member 7 is connected by penetrating the upper part of the concrete beam 8, and it is not easy to cause damage to the concrete beam 8 during drilling; as Figure 8As shown, a through hole 6-1 penetrating left and right is formed in the side wall of the U-shaped bracket 6 along its thickness direction. The through hole 6-1 enables the fixing member 7 to penetrate. The longitudinal cross-sectional shape of the U-shaped bracket 6 along its width direction is U-shaped, with its opening facing upward, for fitting the concrete beam 8 to achieve a multi-sided wrapping effect.
[0049] Furthermore, the fixing member 7 is an existing fixing bolt body.
[0050] The working principle of this specific embodiment is as follows:
[0051] First, install the U-shaped bracket 6 at the designated fixing position of the concrete beam 8. Draw lines and drill holes according to the position of the through hole, and then install the U-shaped bracket 6 on the concrete beam 8 through the fixing member 7.
[0052] Second, install the upper fixing plate 5 at the bottom of the U-shaped bracket 6. Then install the buffer member 4 at the bottom of the upper fixing plate 5 through bolts. Then install the buffer member 4 at the bottom of the upper fixing plate 5, and at the same time connect the buffer member 4 with the sliding member 3.
[0053] Third, adjust the installation position of the lower suspension rod body 1. During installation, loosen the lower nut 2-2 of the adjusting member 2, and the small suspension rod body 1 moves downward under the action of gravity. When it reaches the fixed position, fix the lower suspension rod body 1. After fixing, tighten the lower nut 2-2, and its torque is 20-40 NM. Then tighten the upper nut 2-3, and its torque is 50-90 NM. At this time, the buffer member can buffer both tensile force and impact force. Finally, lock the locking bolt 3-4 on the sliding member 3 so that the sliding sleeve 3-1 is secondarily reinforced and connected to the lower suspension rod body 1.
[0054] In this specific embodiment, the U-shaped bracket 6 and the lower suspension rod body 1 can also be fixed at the designated position first, and finally the height of the sliding member 3 is adjusted through the adjusting member 2, and the buffer member 4 is fixed to the upper fixing plate 5.
