Detailed Description
The present application is described in further detail below with reference to figures 1-3.
Example 1
The embodiment 1 of the application discloses section steel upper portion post reinforcing bar reserves sleeve and mounting structure thereof.
Referring to fig. 1, a telescopic mounting structure is reserved to shaped steel upper portion post reinforcing bar, including punch holder 1 and two lower plate 2, punch holder 1 is used for fixed sleeve 10, and punch holder 1 sets up with two lower plate 2 relatively. Leave the space that the reason pterygoid lamina that is used for shaped steel was worn to establish between punch holder 1 and the lower plate 2, leave the space that the web that supplies shaped steel was worn to establish between two lower plates 2, the both sides of punch holder 1 are connected through first bolt 3 respectively with between one lower plate 2.
The implementation principle of the installation structure of the section steel upper column steel bar reserved sleeve in the embodiment 1 of the application is as follows: according to the position of the sleeve 10 required to be installed, the upper clamping plate 1 and the lower clamping plate 2 are placed on two surfaces of the flange plate of the section steel and then fixed by the first bolts 3. The upper clamping plate 1 is then used for welding the sleeve 10, so that the sleeve 10 does not need to be welded on the flange plate of the section steel, and the condition that the sleeve 10 is welded on the section steel to influence the quality and the supporting force of the section steel is avoided. Meanwhile, after the sleeve 10 welded on the upper clamping plate 1 is inserted with the steel bar, the steel bar pushes the sleeve 10 to drive the upper clamping plate 1 to cling to the flange plate of the section steel.
Referring to fig. 1, a sleeve is reserved to shaped steel upper portion post reinforcing bar, including the sleeve 10 that has shaped steel upper portion post reinforcing bar to reserve telescopic mounting structure, sleeve 10 fixed mounting is in punch holder 1, and sleeve 10 has a plurality ofly.
The implementation principle of the section steel upper portion post reinforcing bar reservation sleeve of this application embodiment 1 does: and welding a corresponding number of sleeves 10 on the upper clamping plate 1 according to the number of the steel bars to be inserted, and then inserting the steel bars into the sleeves 10.
Example 2
The embodiment 2 of the application discloses section steel upper portion post reinforcing bar reserves sleeve and mounting structure thereof.
Referring to fig. 2 and 3, a structural steel upper column steel bar reserved sleeve mounting structure is different from embodiment 1 in that at least two first bolts 3 are arranged between a single lower clamp plate 2 and an upper clamp plate 1, and at least one first bolt 3 is arranged between the two lower clamp plates 2 and the upper clamp plate 1. This is advantageous in increasing the stability of the upper and lower clamping plates 1 and 2 in clamping the flange plate of the steel section.
Two lower plate 2 are close to the equal fixed mounting in one side of punch holder 1 and have first limiting plate 5, and one side fixed mounting that punch holder 1 is close to lower plate 2 has two second limiting plates 6. When the centre gripping was followed the pterygoid lamina at shaped steel at punch holder 1 and two 2 lower plate's of lower plate, first limiting plate 5 supported and pasted in the lateral wall and the punch holder 1 of the reason pterygoid lamina of shaped steel, and second limiting plate 6 supported and pasted in first limiting plate 5 and lower plate 2. Through first limiting plate 5 and the mutual joint of second limiting plate 6, the convenience is using fixed punch holder 1 of first bolt 3 and lower plate 2 like this, prevents that lower plate 2 from inclining when fixed.
Referring to fig. 2 and 3, the first limiting plate 5 is provided with a first screw hole 7, the first screw hole 7 is penetrated by the second bolt 4, and the second limiting plate 6 is provided with a second screw hole 8 for the second bolt 4 to penetrate. The second bolt 4 passes through the first screw hole 7 and the second screw hole 8 and abuts against the side wall of the flange plate, which is beneficial to keeping the upper clamping plate 1 and the lower clamping plate 2 fixed on the flange plate of the section steel.
The implementation principle of the installation structure of the section steel upper column steel bar reserved sleeve in the embodiment 2 of the application is as follows: the upper and lower clamping plates 1 and 2 are placed on both sides of the flange plate of the section steel according to the position where the sleeve 10 is to be installed. At the moment, the two first limiting plates 5 abut against the two sides of the flange plate, and one side of each first limiting plate 5, which is far away from the lower clamping plate 2, abuts against the upper clamping plate 1; the second limiting plate 6 abuts against the first limiting plate 5, and one side, far away from the upper clamping plate 1, of the second limiting plate 6 abuts against the lower clamping plate 2. Then, a second bolt 4 passes through the first screw hole 7 and the second screw hole 8 simultaneously and abuts against the side wall of the flange plate. The upper and lower clamping plates 1 and 2 are then fixed by the first bolts 3.
Through above-mentioned scheme, this is favorable to fixed upper plate 1 and lower plate 2 to install in the position of shaped steel to when making things convenient for follow-up grafting reinforcing bar, the reinforcing bar aligns with sleeve 10.
Referring to fig. 2 and 3, a section steel upper column steel bar reserved sleeve is different from that of embodiment 1 in that a sleeve 10 includes an inner cylinder 101 and an outer cylinder 102, the outer cylinder 102 is fixedly mounted on an upper clamp plate 1, an inner wall of the outer cylinder 102 is in threaded connection with an inner wall of the inner cylinder 101, a knob 11 is fixedly sleeved at one end of the inner cylinder 101, which is far away from the upper clamp plate 1, and a filling opening 9 is formed in a cylinder wall of the outer cylinder 102.
The implementation principle of the section steel upper portion post reinforcing bar reservation sleeve of embodiment 2 of this application is: when the positions of the section steel and the reinforcing steel bar are fixed and the length of the reinforcing steel bar is too long to be inserted into the sleeve 10, the knob 11 is rotated to drive the inner cylinder 101 to retract into the outer cylinder 102, so that the reinforcing steel bar is aligned with the sleeve 10, then the inner cylinder 101 is rotated to increase the length of the inner cylinder 101 penetrating out of the outer cylinder 102, and the reinforcing steel bar is inserted into the sleeve 10. Afterwards, non-shrinkage grouting material is poured into the sleeve 10 through the pouring opening 9, and the gap inside the sleeve 10 is filled with the non-shrinkage grouting material, so that the stability of the steel bar inserted into the sleeve 10 is improved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
