Description

Technical Field

[0001] The invention belongs to the technical field of industrial building engineering, and in particular relates to a tool for quickly installing a steel column with a cup-shaped foundation and a construction method thereof. Background Art

[0002] During the installation of the steel column of the cup-mouth type foundation, the cup-mouth size is generally set to a square, and the upper mouth size is large and the lower mouth size is small, mainly for the convenience of demoulding during civil construction. During the steel column installation process, due to the large distance between the column wall and the cup-mouth size, the steel column inserted into the cup-mouth part is in an active state when installing the steel column, and is positioned on all sides with steel wedges, and fixed on the top with a hand winch and a wire rope. During the alignment process, it is necessary to repeatedly adjust the position of the four steel wedges, which is very cumbersome, and any change in the steel wedges on any of the four sides may cause the entire steel column to shift and tilt. Due to the cumbersome positioning of the steel columns, the installation speed of the steel columns is slow, with an average of 4 steel columns installed per working day. At the same time, when the cup-mouth concrete is poured after the steel column is installed, if the steel wedge is displaced or falls off due to the vibration of the vibrating rod, the overall displacement of the steel column will be caused, which will bring inconvenience to the subsequent structural construction or require reinstallation, and even cause quality accidents such as steel column dumping.

[0003] Disadvantages of existing technology

[0004] 1. Since the steel column has no anchor bolts, it cannot be effectively fixed when inserted into the cup mouth, which has a high risk factor;

[0005] 2. Each steel column is fixed by four positioning steel wedges, and the alignment process is very difficult;

[0006] 3. During the concrete grouting process, the steel column is prone to displacement or even tilt;

[0007] 4. After grouting, the steel wedges are poured into the concrete, making them difficult to remove. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a tooling for quickly installing a steel column with a cup-shaped foundation and a construction method thereof, so as to solve the problems in the prior art that the steel column cannot be fixed and is prone to displacement or even tilting, has a high risk factor, and components cannot be recycled and have a high consumption.

An auxiliary tool 5 is installed at the entrance of the cup-mouth 2, and the auxiliary tool 5 comprises a first positioning member and two second positioning members, the first positioning member and the second positioning member are perpendicular to each other and are welded and fixed together, the first positioning member is made of 16 channel steel, the length of which exceeds the maximum size of the two cup-mouths, and a bolt hole is respectively arranged at both ends, each second positioning member is made of 16 channel steel, the length of each second positioning member exceeds the edge of the cup-mouth in another direction, and a bolt hole is arranged, that is, each second positioning member extends away from one end of the first positioning member and is supported on the side wall at the entrance of the cup-mouth, and the end is provided with a bolt hole for fixing the second positioning member. The distance between the two second positioning members is determined according to the center size of the two steel columns. The spacing between the two second positioning members is equal to the distance between the center lines of two adjacent cup mouths. The distances from the first positioning member and the second positioning member to the center line of the cup mouth are equal and equal to the radius of the steel column. The first positioning member and the second positioning member cooperate to locate the installation position of the steel column. A first wedge block and a second wedge block are also inserted at the entrance of the cup mouth. The first wedge block is inserted between the steel column and a side surface of the cup mouth parallel to the first positioning member. The first degree of freedom of horizontal movement of the steel column is limited by the cooperation of the first wedge block and the first positioning member. The second wedge block is inserted between the steel column and a side surface of the cup mouth parallel to the second positioning member. The second wedge block and the second positioning member cooperate to limit the second degree of freedom of horizontal movement of the steel column.

[0031] The cross-sections of the first wedge block and the second wedge block are both right-angled trapezoids, and the right-angle waists of the first wedge block and the second wedge block fit with the steel column. The first wedge block and the second wedge block have the same specifications and are both made of steel wedges 3 by cutting scrap steel plates on site. The steel wedge 3 is characterized by being wide at the top and narrow at the bottom.

[0032] The construction method of the tooling for quickly installing a steel column with a cup-shaped foundation comprises the following steps:

[0033] Step 1: According to the intersection of the cup mouth 2, use the total station to accurately locate and measure each cup mouth foundation 1, and draw the center line of the cup mouth 2 on each cup mouth foundation 1;

[0034] Step 2: According to the outer dimensions of the steel column 4 to be installed, that is, the radius of the steel column 4, draw the edge lines of the steel column 4 in two directions perpendicular to each other, that is, draw the horizontal and vertical edge lines of the steel column respectively, and draw the horizontal and vertical edge lines A of the steel column in two directions of the center line according to the drawn center line and the outer dimensions of the steel column 4;

[0035] Step 3, take a welded auxiliary tool 5, and make several sets of quick installation auxiliary tools offline (according to the actual installation situation, generally install about 10 per day, make 20 and reuse them, which is more suitable for projects with more steel frame columns). The distance B between the two transverse channel steels is determined according to the center distance between the two column steel pipes of each group of steel frame columns. Make the two edges of the right angle inside of the first positioning workpiece and the second positioning workpiece of the auxiliary tool 5 coincide with the edge lines of the steel column drawn in step 2, and then pass the expansion bolts through the bolt holes on the auxiliary tool and fix the auxiliary tool 5 on the cup mouth foundation;

[0036] Step 4: adjust and install the shim 7 at the bottom of the cup mouth 2, then hoist the steel column by a crane and slowly place it on the shim 7, and the steel column 4 is tangent to the first positioning workpiece and the second positioning workpiece at the same time;

[0037] Step 5, take the first wedge and the second wedge, insert the first wedge between the steel column 4 and the side of the cup 2 parallel to the first positioning piece, insert the second wedge between the steel column 4 and the side of the cup 2 parallel to the second positioning piece, align the center line of the steel column 4, and then wed the first wedge and the second wedge to fix the steel column;

[0038] Step six, after the center line of steel column 4 is aligned and the technical requirements such as verticality and elevation meet the specifications, secondary grouting can be carried out. Start grouting. When the grouting strength reaches 50%, remove the auxiliary tools, the first wedge and the second wedge, and continue grouting until the steel column 4 is installed. After all steel columns 4 are installed, the auxiliary tools 5 can be reused to make pipe supports, etc. to ensure that materials are not wasted.
