Description

TECHNICAL FIELD

[0001] The utility model belongs to bridge construction technical field relates to a kind of assembled wall rod connecting device, for the support of bridge high pier cast-in-place construction erection, tower crane, the wall connection of pedestrian tower ladder. BACKGROUND

[0002] When bridge high pier cast-in-place construction, temporary structure such as support, tower crane, pedestrian tower ladder needs to be set in the column, with the increase of column construction height, the height of temporary structure also increases accordingly, to ensure the stability of temporary structure, it is necessary to set wall rod between temporary structure and column every certain height.

[0003] The conventional wall rod installation mode is to set embedded steel plate on the column according to the design installation position of each wall rod, and to weld wall rod between support and embedded steel plate of column during the subsequent erection of temporary structure such as support. This method requires high-altitude welding operation, and the embedded steel plate cannot be disassembled and can only be permanently retained on the column, which will form a corrosion channel after rusting in the later period and adversely affect the column structure. SUMMARY

[0004] The utility model aims at the above problems, and provides an assembled wall rod connecting device, which is convenient for wall rod installation and avoids affecting the quality of column.

[0005] The technical scheme of the utility model is as follows:

[0006] An assembled wall rod connecting device is arranged on the column, characterized by comprising four anchor bars, an anchor steel plate and four connecting screws. The four anchor bars are embedded in the concrete of the column as the four vertices of a rectangle, and the front end of each anchor bar is directed to the outside of the column and is screwed with an internal thread sleeve. The anchor steel plate is provided with four through holes corresponding to the four anchor bars, and the front end of each connecting screw passes through the four through holes of the anchor steel plate and is screwed with the internal thread sleeve at the front end of the four anchor bars. The rear end of each anchor screw is screwed with an external thread sleeve, and the anchor steel plate is pressed against the side wall of the column through the external thread sleeve. A connecting rod is welded to the outside of the anchor steel plate, the connecting rod is provided with at least two screw holes, and the wall rod is connected to the connecting rod through high-strength bolts.

[0007] The utility model adopts an assembled installation structure, which is convenient to install and can avoid high-altitude welding operation. The wall rod connecting structure is firm and reliable. The anchor steel plate on the column can be disassembled, which can avoid the formation of a corrosion channel on the column in the later period, is beneficial to the protection of the quality of the column, and the anchor steel plate can be reused, saving cost.

[0008] Figure 1 is the elevation structure schematic view of the utility model;

[0009] Figure 2 is a plane structure schematic view of the utility model;

[0010] Figure 3 is a front view structure schematic view of the utility model. DETAILED DESCRIPTION

[0011] As Figure 1 , Figure 2 , Figure 3 The utility model is set up on the pier body 10, including 4 anchor bars 1, an anchor steel sheet 2 and 4 connecting screw rods 3, 4 anchor bars 1 are embedded in the pier body concrete according to the 4 vertexes of rectangle, and each anchor bar 1 front end is towards the pier body outside and is screwed with an internal thread sleeve 4, the anchor steel sheet is set with 4 through holes corresponding 4 anchor bars, and the 4 connecting screw rods 3 front end respectively passes through the 4 through holes on the anchor steel sheet 2 and is screwed with the internal thread sleeve 4 of 4 anchor bars front end, and each anchor screw rod 3 rear end is screwed with an external thread sleeve 5, and the anchor steel sheet 2 is pressed on the pier body 10 lateral wall through the external thread sleeve 5;The anchor steel sheet 2 outside is welded with a connecting rod 6, the connecting rod is set with at least two screw holes, and is connected with the wall attaching rod 8 through high-strength bolt 7.

[0012] The utility model is used for the bridge pier pouring construction, according to the design installation position of each wall attaching rod, embeds anchor bar in the pier body concrete, and pre-screws the internal thread sleeve in the anchor bar front end;When the wall attaching rod is installed, the anchor steel sheet is fixed on the pier body through the connecting screw rod and the external thread sleeve, and the wall attaching rod and the connecting rod on the anchor steel sheet are connected through high-strength bolt, so high-altitude welding operation can be avoided. After the pier column construction is completed, the anchor steel sheet is unloaded from the pier body, and the same reference numeral concrete is used to repair the anchor bar front end through hole on the pier body, so that the rust channel formed on the pier body in the later period can be avoided;The anchor steel sheet that is dismantled can be repeatedly used.
