Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a T-bolt anchor barrel fixing frame and an installation method of the T-bolt anchor barrel. Background Art

[0002] Large rolling mills, main motors and other equipment in metallurgical production lines generally use T-type anchor bolts. Common bolt types include single, double, triple, quadruple, etc. T-bolt anchor cylinders need to be embedded during foundation construction. T-bolts for large equipment are relatively large, with diameters ranging from M56-M140 and a maximum length of 5600mm. Large equipment has high requirements for the position of bolts. The embedded position, elevation, and verticality of the anchor cylinder are directly related to the installation of T-bolts. The embedded accuracy of the anchor cylinder is affected by many factors during the construction process. Movement during concrete construction or steel bar construction will affect the embedded accuracy of the anchor cylinder. Unreliable bolt fixing frames, measurement errors, movement during concrete construction or steel bar construction, etc.

[0003] T-bolt anchor barrels are currently cut and installed on site. The position, elevation, and verticality of the T-bolt anchor barrel are adjusted by moving the anchor barrel and adding or removing pads. After installation, the whole is cast. This method has low on-site production efficiency, and the overall support is poor. Each positioning adjustment requires measurement, and adjustments such as elevation and verticality require the preparation of multiple pads. Adjustments are labor-intensive and time-consuming. When fixing, it is also necessary to add oblique supports to ensure the stability of the anchor barrel and the bracket. In addition, it is impossible to form standardized operations for various forms of T-type anchor bolts, which are greatly affected by construction personnel factors, and the quality of on-site production welding positioning cannot be guaranteed.

[0046] Embodiment 2:

[0047] like Figures 3 to 6 As shown, the present invention also discloses a method for installing a T-bolt anchor cylinder. Based on the fixing frame 2 in the first embodiment, the T-bolt anchor cylinder 3 (quadruple-row T-bolt anchor cylinder) includes an anchor box 31, an anchor plate 32 and four sleeves 33. The anchor plate 32 is fixed on the anchor box 31. The four sleeves 33 are arranged on the anchor plate 32 and communicate with the anchor box 31. Specifically, the installation method includes the following steps:

[0048] Step S1, carrying out the construction process of the bottom steel bar 1 of the equipment foundation.

[0049] Before the construction process of the bottom steel bar 1 of the equipment foundation is carried out, the above installation method also includes the step of prefabricating the fixing frame 2 in the above embodiment 1, that is, according to the structural characteristics of the T-bolt anchor cylinder, a prefabricated and adjustable fixing frame is made using steel and bolts. The prefabrication method of the fixing frame 2 includes:

[0050] First, the vertical pole 21 is cut according to the installation elevation of the bottom of the T-bolt anchor cylinder 3 and the distance between the bottom steel bar 1 of the equipment foundation. The vertical pole 21 uses 25# channel steel. Specifically, the length of the vertical pole 21 is the distance A between the bottom steel bar 1 of the equipment foundation and the 1 / 4 length position of the sleeve 33.

[0051] Secondly, the transverse support rod 22 is made of angle steel, and a position adjustment hole 221 is opened at both ends of the transverse support rod 22. The length of the transverse support rod 22 is 180-220 mm longer than the width of the anchor box 31. Specifically, the transverse support rod 22 is made of angle steel with a size of 100*100*5, and the length is 200 mm longer than the width of the anchor box 31. A long hole is opened on the transverse support rod 22 as the position adjustment hole 221. The aperture of the position adjustment hole 221 is 32 mm and the length is 100 mm.

[0052] Again, the transverse support rod 22 is welded to the vertical pole 21 according to the installation elevation of the bottom surface of the anchor plate 32 of the anchor box 31 to the height of the bottom steel bar 1 of the equipment foundation; specifically, the surface of the transverse support rod 22 is flush with the surface of the vertical pole 21, and the height of the transverse support rod 22 from the bottom of the vertical pole 21 is less than the height of the installation elevation of the bottom surface of the anchor plate 32 to the height of the bottom steel bar 1 of the equipment foundation, and the difference between the two is about 100 mm.

[0053] Then, the transverse adjustment rod 23 is made of a square tube, and the length of the transverse adjustment rod 23 is 180 to 220 mm longer than the length of the anchor box 31 ; specifically, the transverse adjustment rod is made of a 80*80*4 square tube, and the length is 200 mm longer than the length of the anchor box 31 .

[0054] Afterwards, first nuts 25 are fixed to both ends of the bottom of the lateral adjustment rod 23 , and the first nuts 25 are welded to the bottom of the square tube at a position 50 mm away from the end.

[0055] Then, the transverse adjustment rod 23 is assembled with the transverse support rod 22 through the bolt 24, the first nut 25, the second nut 26, and the bolt 24 is tightened to form the fixing frame 2. This assembly step can also be performed on site in step S2.

[0056] Step S2, prefabricate the fixing frame 2 in the above-mentioned embodiment 1, and place the fixing frame 2 under the installation position of the T-bolt anchor tube 3, and after roughly aligning the center line of the fixing frame 2 with the installation center line of the T-bolt anchor tube 3 (preliminary alignment by naked eye observation), the vertical pole 21 of the fixing frame 2 is firmly welded to the bottom steel bar 1 of the equipment foundation.

[0057] Step S3, pouring concrete to the primary pouring surface to fix the fixing frame 2 again, and the distance between the primary pouring surface and the top surface of the lateral adjustment rod 23 is 180-220 mm (for example, 180 mm, 200 mm, 210 mm or 220 mm, etc.).

[0058] Step S4, measure the installation center line of the T-bolt anchor cylinder 3 and mark it on the fixing frame 2, loosen the bolt 24 of the fixing frame 2, and determine the installation position of one side of the anchor box 31 according to the installation center line, and adjust the position of the lateral adjustment rod 23 on one side of the fixing frame 2 according to the installation position of the side of the anchor box 31, that is, adjust the position of the lateral adjustment rod 23 to a position that subsequently contacts the side of the anchor box 31.

[0059] It should be noted that the T-bolt anchoring tube 3 can be assembled in advance, or can be assembled by welding on site according to the installation drawing.

[0060] Step S5, hoist the T-bolt anchor cylinder 3, and make the connection between one side of the anchor box 31 and the anchor plate 32 close to the adjusted one side lateral adjustment rod 23, and weld the second nut 26 to the lateral support rod 22 to form one side positioning.

[0061] Step S6, adjust the lateral adjustment rod 23 on the other side to the other side of the anchor box 31, and after the adjustment is completed, weld the second nut 26 on the other side to the lateral support rod 22, and the front, back, left and right positioning is completed; to support the entire anchor sleeve 33.

[0062] Step S7, placing a level meter on the anchor plate 32, and accurately adjusting the elevation and levelness of the T-bolt anchor cylinder 3 through the bolts 24 at the four corners;

[0063] Step S8, welding the anchor plate 32 and the fixing frame 2 together to form an integral structure.

[0064] Step S9, carrying out the construction process of the top layer of steel bars 4, and pouring concrete in layers to the finished surface of the foundation.

[0065] It should be noted that when carrying out the construction process of the top layer of steel bars 4, the upper part of the sleeve 33 needs to be firmly fixed to avoid position movement during the pouring process.

[0066] Specifically, a sealing plate 34 is provided at one end of the sleeve 33 away from the anchor plate 32; therefore, after pouring the concrete in layers to the finished surface of the foundation, the installation method also includes the step of removing the sealing plate 34, and then inserting the T-bolt into the sleeve 33 and rotating it 90° to complete the installation of the T-bolt.
