Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction protection device for anti-floating anchor rods. Background Technique

[0002] An anti-floating anchor rod refers to a structural member set to resist the upward displacement of the building thereon, which is related to the level and change of the groundwater level, and is opposite to the stress direction of the compression pile. After the anti-floating anchor rod is constructed, it needs to be maintained for a long period. During the maintenance period, it is strictly prohibited to touch the exposed anchor head steel bars by external force. Therefore, it needs to be protected. The existing protection devices have poor protection for the anchor head steel bars, and the orientations of the anchor head steel bars cannot be kept in the same position. The existing protection devices have poor flexibility and cannot be fully applicable.

[0003] According to a finished product protection device during the construction of an anti-floating anchor rod disclosed in the Chinese utility model publication specification CN216787238U, it includes a support plate. A support rod is provided at the bottom end of the support plate, and a buried pile head is provided at the bottom end of the support rod. A bracket is provided on the upper surface of the support plate. In the device provided by the utility model, the anchor rod steel bars and grouting pipes for grouting are limited by the support plate. The limiting holes on the support plate can limit the anchor rod steel bars, and the grouting pipe heads on the support plate are fixed, which is convenient for protecting the grouting pipes and anchor rods during the construction process and during the waiting period for secondary grouting when the work is not completed.

[0004] However, the protection device with such a setting has poor protection for the exposed anchor head steel bars, and can only protect the straight steel bars at the top end. When the bent anchor head steel bars face around, the upper ends of the anchor head steel bars cannot be kept in the same position, and the lower end of the steel bar is fixed in the anchor rod. Therefore, the orientation of the upper end of the steel bar is fixed and cannot be adjusted. The existing protection device has poor flexibility and cannot be fully applicable, resulting in some steel bar heads being protected and some protruding out of the protection sleeve.

[0005] Based on this, the utility model designs a construction protection device for anti-floating anchor rods to solve the above problems. Utility Model Content

A fixing screw 10 is threadedly connected inside the positioning slider 9, and an installation convex plate 11 is sleeved outside the fixing screw 10.

[0033] It should be noted that when protecting the anchor head steel bar 18, the first protective cylinder 3 and the second protective cylinder 4 are sleeved outside the anchor head steel bar 18, and the first protective cylinder 3 and the second protective cylinder 4 are combined. They are fixedly locked through the docking lock plate 5 and the locking bolt 6, so that the first protective cylinder 3 is attached to the surface of the foundation 1 and fixed by the installation screw 15. The limiting member 7 is inserted into the first protective cylinder 3, and the positioning slider 9 is slid to a suitable position, and then the positioning slider 9 is positioned and locked by the adjusting bolt 12. At this time, the fixing screw 10 is connected to the positioning slider 9 to fix the installation convex plate 11, completing the installation of the protective cover 14, thereby realizing the protection of the anchor head steel bar 18 and preventing the anchor head steel bar 18 from being impacted. When installing the protective cover 14, the number of the installation arc plates 8 is set to two, corresponding to the first protective cylinder 3 and the second protective cylinder 4, and a plurality of positioning sliders 9 are arranged inside the installation arc plate 8. The sliding range of the positioning slider 9 approaches a complete circle, so that the installation position of the protective cover 14 can be flexibly changed following the anchor head steel bar 18, thereby achieving the purpose of protecting the anchor head steel bar 18 at different installation positions. The anchor head steel bar 18 is stuck in the groove of the protective cover 14, thus protecting the anchor head steel bar 18.

[0034] As shown Figure 2 in the figure, an adjusting bolt 12 is slidably connected inside the mounting arc plate 8. The adjusting bolt 12 is inserted into the positioning slider 9. One side of the mounting convex plate 11 is fixedly equipped with a protective cover 14. The structure of the protective cover 14 is as shown Figure 4 in the figure. The protective cover 14 is a card slot with an open top and closed sides. The bottom of the protective cover 14 is also closed, and the bottom of the protective cover 14 is an inclined baffle. The inner side of the protective cover 14 is a stepped clamping platform. The protective cover 14 can be detachably clamped on the tops of the first protective cylinder 3 and the second protective cylinder 4. The inner opening of the protective cover 14 abuts against the outer side walls of the first protective cylinder 3 and the second protective cylinder 4;

[0035] An installation convex plate 11 is also provided at the inner bottom edge of the protective cover 14. A fixing screw 10 is provided on the outer side wall of the positioning slider 9. The installation convex plate 11 is locked on the positioning slider 9 through the fixing screw 10;

[0036] As shown Figure 1 in the figure, a mounting screw 15 is inserted into the base 2. The mounting screw 15 is threadedly connected to the foundation 1. A splicing baffle 16 is provided at the top of the protective cover 14. As shown Figure 3 in the figure, a splicing baffle 16 is provided at the top of the protective cover 14. A positioning pin 17 is inserted at the bottom of the splicing baffle 16. The splicing baffle 16 is inserted and connected to the top of the protective cover 14 through the positioning pin 17. As shown Figure 1 in the figure, anchor head steel bars 18 are provided inside the foundation 1.

[0037] It should be noted that when the exposed height of the anchor head steel bars 18 is relatively high, the overall height of the protective cover 14 can be increased by adding a splicing baffle 16 and connecting and fixing it through the positioning pin 17, so as to completely protect the anchor head steel bars 18 and avoid the phenomenon that the protective cover 14 is not tall enough to cause incomplete protection.

[0038] When the device is in use, the two bases 2 are tightened at the joint of the anti-floating anchor rod and the foundation 1 to form a hoop. The first protective cylinder 3 and the second protective cylinder 4 are also in the form of a hoop and are locked into an integral cylindrical structure through the locking bolt 6 and the docking lock plate 5 to ensure the stable hinge of the first protective cylinder 3 and the second protective cylinder 4. And the complete cylinder formed by the first protective cylinder 3 and the second protective cylinder 4 is sleeved and placed above the base 2. The base 2 and the protective cylinder structure can be an integral structure, two semi-circular pieces, assembled into a complete cylinder. The role of the base 2 is to form a more stable support with the foundation 1, and a complete cylinder is formed through the first protective cylinder 3 and the second protective cylinder 4 to protect the anchor head steel bars 18.

[0039] An arc plate 8 is sleeved and installed outside the cylinders of the first protective cylinder 3 and the second protective cylinder 4 to make the hoop more stable. A plurality of positioning sliders 9 are installed on the installation arc plate 8. The positioning sliders 9 are limited and slid on the installation arc plate 8 through adjusting bolts 12.

When locking is required, the adjusting bolt 12 is tightened, and the positioning slider 9 is locked on the installation arc plate 8.

[0040] A chute is horizontally opened on the outer wall of the installation arc plate 8. The chute on the outer wall of the installation arc plate 8 is a U-shaped groove opening outward. The top and bottom of the chute of the installation arc plate 8 both extend to form an arc-shaped horizontal chute, and the upper and lower sides are blocked, so that the positioning slider 9 slides in the chute on the outer wall of the installation arc plate 8, and the inner side of the positioning slider 9 has the same radian as the outer side wall of the installation arc plate 8.

[0041] A waist-shaped hole is also provided at the top of the installation arc plate 8. The waist-shaped hole penetrates through the upper and lower baffle plates of the outer chute of the installation arc plate 8, and the adjusting bolt 12 penetrates through the chute of the installation arc plate 8 from top to bottom and simultaneously penetrates through the positioning slider 9, so that the adjusting bolt 12 limits the positioning slider 9 and can carry it to slide synchronously.

[0042] The protective cover 14 is a double-plate groove-shaped structure, which is convenient for restricting and protecting the protruding anchor head steel bars 18. It not only avoids injuries to passing personnel outside, but also protects the anchor head steel bars 18 from being bent and damaged by other equipment.

[0043] The protective cover 14 is locked and installed on the positioning slider 9 through the fixing screw 10. When the positioning slider 9 slides, the protective cover 14 follows to slide, and when the positioning slider 9 is locked, the position of the protective cover 14 is fixed and locked. Such a structure can not only adjust the position of the protective cover 14, but also lock the protective cover 14, so as to protect the protruding anchor head steel bars 18. Moreover, the top of the protective cover 14 can continue to be stacked and extended, and the splicing baffle 16 is limited on the protective cover 14 through the positioning pin 17 to form two-sided protection, so as to effectively protect the anchor head steel bars 18 at different height positions.
