A connection piece between a prefabricated column and a prefabricated foundation

Abstract

The utility model relates to the technical field of building construction, and discloses a connecting piece between a prefabricated column and a prefabricated foundation, comprising a connecting base plate, a through hole formed on the connecting base plate, four first mounting holes formed on the connecting base plate, and anchor rods are arranged on the inner sides of the four first mounting holes. The utility model relatively fixes the prefabricated column and the hollow seat by arranging a second mounting hole, a slide rail, a protective cover plate, a first air vent, a placement shell, an insertion hole and a second air vent, and uses bolts to pass through the second mounting hole. After the fixing is completed, the protective cover plate is put back along the two slide rails, and the protective cover plate can block all the bolts to prevent the bolts from being corroded by rainwater when it rains. Since the second air vent is connected with the first air vent and the internal cavity of the placement shell, water-absorbing material is put into the insertion hole to prevent the protective cover plate from being damp and causing the bolts to rust. Compared with the prior art, the bolts can be prevented from being easily rusted after raining, causing the connection position to loosen and causing safety hazards.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the embodiment, Figure 1-4 Provided is a connector between a prefabricated column and a prefabricated foundation, comprising a connecting base plate 1, a through hole 2 being opened on the connecting base plate 1, four first mounting holes 3 being opened on the connecting base plate 1, anchor rods 4 being arranged on the inner sides of the four first mounting holes 3, a hollow seat 5 being fixedly connected to the top end of the connecting base plate 1, the inner cavity of the hollow seat 5 being communicated with the through hole 2, four reinforcing plates 6 being fixedly connected to the outer side of the hollow seat 5, the four reinforcing plates 6 being fixedly connected to the top end of the connecting base plate 1, four second mounting holes 7 being opened on the front and rear ends of the hollow seat 5, and protective components 8 for preventing raindrops from falling into the second mounting holes 7 being arranged on the front and rear ends of the hollow seat 5;

[0022] The protection assembly 8 includes a slide rail 81, a protection cover plate 82, a first vent hole 83, a placement shell 84, a placement hole 85, and a second vent hole 86. Four slide rails 81 are fixedly connected to the hollow seat 5. The outer sides of the two adjacent slide rails 81 on the left and right are slidably connected to the protection cover plate 82. The protection cover plate 82 is in close contact with the hollow seat 5. The first vent hole 83 is opened on the protection cover plate 82. The protection cover plate 82 is fixedly connected to the placement shell 84. The bottom end of the placement shell 84 is opened with a placement hole 85 connected to the internal cavity of the placement shell 84. A second air hole 86 connected to the first air hole 83 is provided on the placement shell 84, and the second air hole 86 is connected to the internal cavity of the placement shell 84. It should be noted that the top end of the protective cover 82 is sealed, while the bottom end is not sealed and connected to the cavity of the protective cover 82. Therefore, the protective cover 82 can be lifted up and taken out normally, and after being replaced on the two slide rails 81, the protective cover 82 can slide downward along the two slide rails 81 under the action of gravity until the top ends of the two slide rails 81 contact the top end of the inner cavity of the protective cover 82 and then stop moving.

[0023] Through the above settings, first place this connecting part on the top of the prefabricated foundation, and use four anchor rods 4 to pass through the four first mounting holes 3 to relatively fix the prefabricated foundation and the connecting base plate 1, then put the prefabricated column along the cavity of the hollow seat 5 until the prefabricated column is inserted into the interior of the prefabricated foundation, support the protective cover plate 82, and slide the protective cover plate 82 upward along the two slide rails 81 to be taken out, use bolts to pass through the second mounting hole 7, so that the prefabricated column and the hollow seat 5 are relatively fixed. After the fixation is completed, put the protective cover plate 82 back along the two slide rails 81. The protective cover plate 82 can block all the bolts to prevent rainwater from rusting the bolts when it rains. Since the second air vent 86 is connected to the first air vent 83 and the internal cavity of the placement shell 84, the water-absorbing material is placed from the placement hole 85 to prevent the protective cover plate 82 from getting damp and causing the bolts to rust.

[0024] Reference Figure 1-4 , wherein a calcium chloride granule bag is placed inside the placement shell 84;

[0025] Through the above-mentioned structural setting, the calcium chloride particle bag can effectively absorb water to prevent the bolts in the second mounting hole 7 from rusting.
