Problems solved by technology

Since some columns here need to be constructed step by step, the positions and dimensions of the steel columns, the outer steel bars of the steel columns, and the anchor bolts of the columns are closely related, and it is easy to cause deviations during the civil construction process
[0003] Therefore, in view of the above-mentioned problem that the positions of the steel column, steel column outer steel bar, and column anchor bolts are easy to cause deviations, a method that not only ensures the installation dimensional accuracy of the column anchor bolts and steel column outer steel bars, but also saves working hours and manpower It is very necessary to use the bracket for the simultaneous positioning of the steel column anchor bolts and the steel column outer steel bars

Embodiment 1

[0025] image 3 It is a schematic diagram of the layout of the anchor bolts of the steel column and the outer steel bars of the steel column in the embodiment of the present invention. In the bracket used for the simultaneous positioning of steel column anchor bolts and steel column outer steel bars of the present invention, the elevation of the frame column steel column anchor bolts is -6m underground. Set the steel column bottom plate on the outside of the square steel column 8, the steel column bottom plate is 30mm thick, 680mm*680mm square steel plate 4, the steel column bottom plate is welded with four anchor bolts 7 and the gland steel plate, and the anchor bolts are arranged on the square steel plate. Between the column bottom plate and the steel column, 4 anchor bolts are arranged in a square shape, the steel column bottom plate is provided with anchor bolt installation holes 6, the diameter of which is 30mm, and 24 column-wrapped steel bars 5 are regularly arranged ar...

Embodiment 2

[0028] Figure 4 It is a schematic diagram of the use state of the support for the simultaneous positioning of the anchor bolts of the steel column and the outer steel bars of the steel column according to the embodiment of the present invention. The method of using the bracket for the simultaneous positioning of the anchor bolts of the steel column and the outer steel bars of the steel column of the present invention:

[0029] 1. Make the positioning bracket as in Example 1: According to the requirements of the construction drawings, and use the materials on the construction site to make the bracket.

[0030] 2. Install the anchor bolt 7, including the following steps:

[0031] 1) Insert the anchor bolt 7 into the steel pipe 2 of the positioning bracket (the outer diameter of the anchor bolt is 24mm, and the inner diameter of the steel pipe is 27mm), and use the upper and lower nuts 9 to tighten the anchor bolt and fix it on the positioning bracket. The upper nut is fastene...

Abstract

The invention provides a bracket for simultaneous positioning of anchor bolts of a steel column and wrapping reinforcements of the steel column. The bracket comprises an angle steel frame, a steel pipe and a steel plate block, and is characterized in that the angle steel frame is a square frame with the side length being larger than or equal to 730 mm; the steel plate block is a square steel platewith the side length being 100 mm, welded and fixed between the surface of the angle steel frame and the steel pipe and used for enhancing connection between the angle steel frame and the steel pipe.The bracket for simultaneous positioning of the anchor bolts of the steel column and the wrapping reinforcements of the steel column has the advantages of being simple and stable in structure, convenient to manufacture, good in stress, high in strength, high in adaptability when used on a field processing site, field-fabricated, rapid to mount, simple to operate, safe and reliable to use and lowin bracket manufacture cost and reducing engineering cost.

Description

technical field [0001] The invention relates to a bracket, in particular to a bracket used for simultaneous positioning of steel column anchor bolts and steel column outer-wrapped steel bars. Background technique [0002] In the innovation and entrepreneurship project of Caofeidian Comprehensive Free Trade Zone, 1#, 2#, 3#, and 4# office buildings are steel frame structures, and some columns in the basement are in the form of steel columns wrapped with reinforced concrete. Since some columns here need to be constructed step by step, the positions and dimensions of the steel columns, the outer steel bars of the steel columns, and the anchor bolts of the columns are closely related, and deviations are likely to be caused during the civil construction process. [0003] Therefore, in view of the above-mentioned problem that the positions of the steel column, steel column outer steel bar, and column anchor bolts are easy to cause deviations, a method of ensuring the installation ...
