Embodiment 1

[0029] Such as Figure 1 to Figure 3 As shown, a combined pre-embedded hook includes an embedded steel plate 1 pre-embedded in the interior of the concrete through an anchor. The lower surface of the embedded steel plate 1 is fixedly connected with a groove box 2, and the bottom of the groove box 2 is open Setting, the slot box 2 is provided with a positioning unit, the inside of the slot box 2 is provided with a hanging plate 3, the hanging plate 3 is integrally connected with a web 4, and the bottom of the web 4 is provided with a hanging hole, and the slot box 2 is connected with the hanging plate through the positioning unit. Plate 3 realizes the fixed connection.

[0030] In a further preferred solution in this embodiment, the positioning unit includes a positioning plate 5 and a fixing seat 6, and multiple sets of the positioning plate 5 (inverted L-shaped structure) and the fixing seat 6 are arranged, and the positioning plate 5 and the fixing seat 6 are arranged crossw...

Embodiment 2

[0031] Embodiment 2: A construction method of a combined pre-embedded hook, comprising the following steps:

[0032] S1. First, weld the pre-embedded steel plate 1 and the tank box 2 as a whole, and the pre-embedded steel plate 1 is reserved in the concrete;

[0033] S2. After the concrete reaches a certain strength, after removing the formwork, adjust any fixed rod 7 to pull outward, the positioning plate 5 moves outward with the fixed rod 7 to drive the rotating rod to rotate, and a rotating rod located on the same fixed seat 6 passes through The gear 10 meshes to drive another rotating rod to rotate, and at the same time drives the adjacent positioning plates 5 to move outward, so that all the positioning plates 5 move to the side close to the inner wall of the tank box 2;

[0034] S3, the hanging board 3 is inserted into the tank box 2 from the side of the opening of the tank box 2, and then all the positioning claws of its fixing rod 7 are released to move to the hanging ...

Embodiment 3

[0036] Such as figure 1 , Figure 4 to Figure 6 As shown, the difference from Embodiment 1 is that the positioning unit includes a limit frame 11, a locking member 12 and a connecting hole 13, the limit frame 11 is integrally connected to the inner bottom end of the tank box 2, and the inner opening of the limit frame 11 The size is compatible with the hanging plate 3. The locking member 12 is connected to the limit frame 11 by threads. The locking member 12 can be adjusted vertically. The connecting holes 13 are provided at the four corners of the hanging plate 3. After the plate 3 is rotated by 45°, the locking member 12 matches the connecting hole 13 to fix the hanging plate 3 .

[0037] In a further preferred solution in this embodiment, an arc-shaped track 14 is provided on the inner top surface of the tank box 2, and two symmetrical positioning pins 16 are slidably connected in the arc-shaped track 14, and a positioning pin 16 is provided on the hanging plate 3. Holes ...

Abstract

The invention discloses a combined pre-buried hook and a construction method, belonging to the technical field of building construction. The invention comprises a pre-embedded steel plate (1) pre-embedded inside the concrete through an anchor, the lower surface of the pre-embedded steel plate (1) is fixedly connected with a tank box (2), and the bottom of the tank box (2) For open setting, a positioning unit is provided on the tank box (2), and a hanging plate (3) is provided inside the tank box (2), and the hanging plate (3) is integrally connected with a web (4), The bottom of the web (4) is provided with a hanging hole, and the tank box (2) is fixedly connected to the hanging plate (3) through a positioning unit. It helps to improve the accuracy of the embedding position of the pre-embedded hook in the concrete structure, avoids quality problems such as the hook hanging down, can effectively guarantee the use function of the hook and the safety of the hoisting force, and the formed pre-embedded hook is beautifully made.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a combined pre-embedded hook and a construction method. Background technique [0002] In housing construction and municipal infrastructure projects, round steel is generally used to pre-embed in concrete components to make hooks, which are used as hoisting attachment points. It is difficult to accurately control the position and exposed length of the traditional hook made of round steel when it is pre-embedded in the concrete structure. During the construction process, there are often quality problems such as inaccurate embedding position and hanging of the hook, which seriously affect the use function and hoisting. In order to ensure safety, the formwork needs to be destroyed to complete its overall pre-embedded work, and the phenomenon of grout leakage or pitting often occurs at the damaged place, which affects its pre-embedded quality. At the same ti...
