Problems solved by technology

[0003] At present, in the prefabricated structure, the connection of the longitudinal reinforcement of the prefabricated column is usually connected by a grouting sleeve. This connection method has problems such as difficult positioning of the reinforcement and insufficient grouting, which makes the actual operation very difficult.
[0004] Although the existing dry connection using mechanical sleeves to connect longitudinal reinforcements solves the problem of grouting sleeves, the use of mechanical sleeves to connect longitudinal reinforcements requires filling concrete at the joints. Limited area, easy to damage when removing the mold
When using steel formwork, due to the different cross-sectional sizes of the columns on site, steel forms with different cross-sectional sizes are required, and the cost of manufacturing steel molds with different cross-sectional sizes is relatively high

Embodiment 1

[0043] The embodiment of the present application discloses a formwork for connecting nodes of prefabricated columns. Refer again figure 1 , 2 , the top of the formwork is sleeved and surrounded by the bottom side wall of the prefabricated column 1, the bottom end of the formwork is sleeved and surrounded by the top side wall of the existing column 2, and the formwork includes a first baffle member 3 and a second baffle member 4 , the first baffle piece 3 and the second baffle piece 4 are rectangular plates parallel to the sides of the prefabricated column 1a, the first baffle piece 3 and the second baffle piece 4 are all vertically arranged, the first baffle piece 3 and The opposite sides of the second baffle piece 4 are against the side where side a of the prefabricated column 1 is located, and the bottom ends of the first baffle piece 3 and the second baffle piece 4 are against the top side wall of the existing column 2 . An intermediate plate group 5 is connected between...

Embodiment 2

[0060] The difference between implementation 2 and implementation 1 is that, referring to Figure 5 The two ends of the second baffle member 4 along the length direction of side a are also fixedly connected with end plates 6, and the length direction of the end plate 6 of the second baffle member 4 is also parallel to the b side of the prefabricated column 1, and the second connecting plate 13 The end plate 6 fixedly connected to the second baffle 4 is away from the end of the second baffle 4, the second connecting plate 13 is perpendicular to the end plate 6, and one end of the second connecting plate 13 is on the side of the end plate 6 close to the pouring space flush with the opposite end facing away from the pouring space.

Embodiment 3

[0062] The difference between embodiment three and embodiment one is that, referring to Figure 6 , 7 , the first baffle member 3 and the second baffle member 4 both include an inner baffle 19 and an outer baffle 20 that are attached to each other. The inner baffle 19 is located on the side of the outer baffle 20 close to the pouring space, and the inner baffle 19 and the outer baffle 20 are relatively slidably connected in the length direction parallel to side a. At this time, the grouting bucket 8 is fixedly connected to the end plate 6 .

[0063] The end of the inner baffle 19 away from the outer baffle 20 is connected with guide rails 21 , and there are several guide rails 21 distributed along the height direction of the inner baffle 19 at intervals, and there are two guide rails 21 at intervals in the implementation of this application. The guide rail 21 is arranged parallel to the length direction of side a, and a vertical fixed plate is fixedly connected between one e...

Abstract

The invention relates to a formwork of a prefabricated column connecting joint and a joint construction method using the formwork. The formwork of the prefabricated column connecting joint comprises a first baffle piece and a second baffle piece which are attached to the outer side wall of the end of a prefabricated column, and a middle plate set is connected between the end of the first baffle piece and the end of the second baffle piece. The middle plate set comprises two end plates fixedly connected to the end of the first baffle piece and two inserting plates detachably connected between an end plate and the end of the second baffle piece. The first baffle piece, the second baffle piece, the two end plates and the two inserting plates surround the end of the prefabricated column, a pouring space is formed among the first baffle piece, the second baffle piece, the two end plates, the inserting plates, the prefabricated column and the end face of an existing column, and the first baffle piece is further connected with a grouting hopper used for guiding concrete pouring. The formwork of the prefabricated column connecting joint and the joint construction method using the formwork has the effect of improving the adaptability of the formwork to the sectional dimensions of different prefabricated columns.

Description

technical field [0001] The present application relates to the technical field of prefabricated column construction, in particular to a formwork for connecting nodes of prefabricated columns and a node construction method using the formwork. Background technique [0002] With the development of society, prefabricated buildings are being used more and more widely based on their factory prefabrication and environmental protection characteristics. [0003] At present, in the prefabricated structure, the connection of the longitudinal reinforcement of the prefabricated column is usually connected by a grouting sleeve. This connection method has problems such as difficult positioning of the reinforcement and insufficient grouting, which makes the actual operation very difficult. [0004] Although the existing dry connection using mechanical sleeves to connect longitudinal reinforcements solves the problem of grouting sleeves, the use of mechanical sleeves to connect longitudinal r...
