Description

Technical Field

[0001] The utility model belongs to the technical field of anchor rods, and specifically relates to an anti-floating anchor rod fixing device. Background Technique

[0002] Anti-floating anchor rod fixing devices are mostly applied in the field of construction engineering and are key components of underground structure anti-floating measures. By anchoring in stable rock and soil layers, they provide sufficient downward pulling force to resist the buoyancy of groundwater, firmly fixing the building to the ground and ensuring its stability.

[0003] In the use of existing anti-floating anchor rods, usually a drilling machine first drills a deeper hole at the position where the anchor is to be inserted, then the metal anchor rod is inserted along the hole to the bottom of the hole, and a part of the anchor rod is exposed above the ground. Finally, it is formed by pouring concrete. Since the part of the anchor rod exposed above the ground is in a vertical state, loosening may occur, and then the loosening problem is transmitted to the bottom, affecting the overall anti-floating ability of the anchor rod.

[0004] Therefore, the utility model provides an anti-floating anchor rod fixing device. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: An anti-floating anchor rod fixing device described in the utility model includes a frustum-shaped fixing cover; three through holes are evenly distributed on the frustum-shaped fixing cover from top to bottom; a metal anchor rod is inserted and fixedly connected in the through holes; a grouting hole is opened at the center position of the frustum-shaped fixing cover from top to bottom. Through the cooperation of the metal anchor rod and the frustum-shaped fixing cover, the fixation of the metal anchor rod and the frustum-shaped fixing cover on the ground is realized. At the same time, due to the fit of the frustum-shaped fixing cover with the ground, the contact area between the metal anchor rod and the frustum-shaped fixing cover relative to the ground can be increased, making the anchor rod more stable. At the same time, due to the large-area protection at the bottom of the frustum-shaped fixing cover, the soil and water loss around the metal anchor rod can be effectively reduced, thereby improving the stability of the metal anchor rod and the frustum-shaped fixing cover on the ground.

[0007] Preferably, drain grooves are evenly distributed and opened on the surface of the frustum-shaped fixing cover; insertion cone holes are opened in the middle and lower parts of the drain grooves; the liquid flows directly to the ground after passing through the insertion cone holes and will not penetrate into the insertion cone holes, effectively preventing the liquid from corroding or affecting the metal insertion cone. At the same time, through the drain grooves, after the frustum-shaped fixing cover is in contact with the ground for a long time, the penetration of the liquid to the bottom of the frustum-shaped fixing cover is prevented, thereby strengthening the overall stability of the anchor rod.

[0008] Preferably, a metal plug is inserted and fixed in the plug hole; the metal plug and the drainage groove are on the same straight line and are evenly distributed on the upper surface of the frustum-shaped fixing cover together. Through the design of the metal plug, the stable fixation of the frustum-shaped fixing cover to the ground can be achieved. Since the frustum-shaped fixing cover is fixedly connected to the metal anchor rod, the fixation of the metal anchor rod is further realized, enabling the anchor rod to firmly grip the ground as a whole, reducing the risk of loosening when the buoyancy is too large, and increasing the anti-floating capacity of the building.

[0009] Preferably, the metal anchor rods are evenly distributed in a triangular shape, and triangular support rings are evenly fixed inside the metal anchor rods from top to bottom; at the same time, the central positions of all the triangular support rings correspond to the central position of the grouting hole up and down. After the triangular support rings enter the ground holes, since the metal anchor rods are in a relatively deep position in the ground, they will be deformed by the extrusion of the surrounding sidewall soil. Due to the triangular structure design of the triangular support rings, they will give a certain supporting force to the three metal anchor rods to resist the sidewall soil pressure, preventing the metal anchor rods from being deformed, and thus firmly gripping the ground, improving the rehabilitation effect and the stability of the building; at the same time, since the middle of the triangular support rings is designed with a hollow structure, it is more convenient for the insertion of the grouting pipe for grouting.

[0010] Preferably, rod body metal spines are fixedly connected to the metal anchor rods from top to bottom; and the three metal anchor rods are all evenly fixed with rod body metal spines. If only relying on the threads of the metal anchor rods and the frictional force of the sidewall soil to enhance the anti-floating capacity, the anti-floating effect is not obvious. Through the design of the rod body metal spines, after the concrete around the rod body metal spines solidifies, in the case of underground water buoyancy, the rod body metal spines will generate a downward pulling force with the surrounding cement and soil, thereby enhancing the anti-floating effect.

[0011] Preferably, metal barbs are fixedly connected to the bottoms of the metal anchor rods; and the bottoms of the three metal anchor rods are all evenly fixed with metal barbs. Through the barb design of the metal barbs, after the concrete around the metal barbs solidifies, in the case of underground water buoyancy, the metal barbs will hook the surrounding cement and soil and become an integral part with them. Through the combined cooperation of the rod body metal spines and the metal barbs, the anti-floating effect is further enhanced twice, making the entire anti-floating anchor rod in a stable state in all directions, and enhancing the stability of the building.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. For the anti-floating anchor rod fixing device described in the present utility model, through the cooperation of the metal anchor rod and the frustum-shaped fixing cover, the fixation of the metal anchor rod and the frustum-shaped fixing cover on the ground is realized. At the same time, due to the fitting of the frustum-shaped fixing cover to the ground, the contact area between the metal anchor rod and the frustum-shaped fixing cover relative to the ground can be increased, making the anchor rod more stable. At the same time, due to the large-area protection at the bottom of the frustum-shaped fixing cover, the soil and water loss around the metal anchor rod can be effectively reduced, thereby enhancing the stability of the metal anchor rod and the frustum-shaped fixing cover on the ground.

[0014] 2. For the anti - floating anchor rod fixing device of the present utility model, after the triangular support ring enters the ground hole, since the metal anchor rod is at a relatively deep position in the ground, it will be deformed by the extrusion of the surrounding side - wall soil. Due to the triangular structure design of the triangular support ring, it will give a certain supporting force to the three metal anchor rods to resist the side - wall soil pressure, preventing the metal anchor rods from being deformed, and thus stably grasping the ground, improving the rehabilitation effect and the stability of the building. At the same time, because the middle of the triangular support ring is a hollow design, it is more convenient for the grouting pipe to be inserted for grouting. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Such as Figures 1 to 2As shown in the figure, a floating resistance anchor rod fixing device according to an embodiment of the present utility model includes a frustum fixing cover 1; three rotating holes 11 are evenly distributed on the frustum fixing cover 1 from top to bottom; a metal anchor rod 12 is inserted and fixed in the rotating holes 11; a grouting hole 13 is formed in the center position of the frustum fixing cover 1 from top to bottom. During operation, first use a hole drilling machine to open a hole in the ground, and then insert the metal anchor rod 12 into the hole opened on the ground. At this time, the frustum fixing cover 1 is synchronously fixed on the ground. At the same time, the larger opening of the frustum fixing cover 1 needs to be fitted with the ground. Then, grout the anchor rod hole through the grouting hole 13. At this time, the slurry will enter the hole opened on the ground and submerge the middle part of the metal anchor rod 12. After the slurry solidifies, the fixation of the metal anchor rod 12 to the building can be realized; through the cooperation of the metal anchor rod 12 and the frustum fixing cover 1, the fixation of the metal anchor rod 12 and the frustum fixing cover 1 on the ground is realized. At the same time, due to the fit of the frustum fixing cover 1 with the ground, the contact area between the metal anchor rod 12 and the frustum fixing cover 1 relative to the ground can be increased, making the anchor rod more stable. At the same time, due to the large-area protection at the bottom of the frustum fixing cover 1, the soil and water loss around the metal anchor rod 12 can be effectively reduced, thereby improving the stability of the metal anchor rod 12 and the frustum fixing cover 1 on the ground.

[0024] As Figure 2 shown, drainage grooves 2 are evenly distributed and formed on the surface of the frustum fixing cover 1; an inserting cone hole position 21 is formed in the middle and lower part of the drainage grooves 2; by providing the drainage grooves 2, when the frustum fixing cover 1 covers the ground, the liquid diversion at the top of the frustum fixing cover 1 can be realized, and the liquid can be transported to a position far from the metal anchor rod 12, reducing the penetration of the liquid to the contact position between the metal anchor rod 12 and the ground. At the same time, the liquid will not be blocked when flowing down through the inserting cone hole position 21 in the drainage grooves 2; after the liquid flows through the inserting cone hole position 21, it directly reaches the ground and will not penetrate into the inserting cone hole position 21, effectively preventing the liquid from corroding or affecting the metal inserting cone 3. At the same time, through the drainage grooves 2, after the frustum fixing cover 1 is in long-term contact with the ground, the penetration of the liquid to the bottom of the frustum fixing cover 1 is avoided, thereby strengthening the overall stability of the anchor rod.

[0025] As Figures 2 to 3As shown, a metal plug 3 is inserted and fixed in the plug hole 21; the metal plug 3 and the drainage groove 2 are on the same straight line and are evenly distributed on the upper surface of the frustum-shaped fixed cover 1 together. By providing the metal plug 3, when the frustum-shaped fixed cover 1 is placed on the ground, the metal plug 3 can be aligned with the plug hole 21 and inserted into the ground, and is fixed to the frustum-shaped fixed cover 1, and each plug hole 21 corresponds to a metal plug 3, which is evenly distributed on the surface of the frustum-shaped fixed cover 1; through the design of the metal plug 3, the stable fixation of the frustum-shaped fixed cover 1 to the ground can be realized. Since the frustum-shaped fixed cover 1 is fixed to the metal anchor rod 12, the fixation of the metal anchor rod 12 is further realized, so that the whole anchor rod firmly grasps the ground, reducing the risk of loosening when the buoyancy is too large and increasing the anti-floating ability of the building.

[0026] As Figure 4 shown, the metal anchor rods 12 are evenly distributed in a triangle, and triangular support rings 4 are evenly fixed inside the metal anchor rods 12 from top to bottom; at the same time, the central positions of all the triangular support rings 4 correspond to the central position of the grouting hole 13 up and down. During operation, when the metal anchor rods 12 are inserted into the ground, since the triangular support rings 4 and the metal anchor rods 12 are fixed, the triangular support rings 4 enter the hole together with the metal anchor rods 12. Subsequently, the grouting pipe is inserted into the grouting hole 13 for grouting, and the grout will wrap the triangular support rings 4 and solidify; after the triangular support rings 4 enter the ground hole, since the metal anchor rods 12 are at a relatively deep position in the ground, they will be deformed by the extrusion of the surrounding sidewall soil. Since the triangular support rings 4 are designed in a triangular structure, they will give a certain supporting force to the three metal anchor rods 12 to resist the sidewall soil pressure, so that the metal anchor rods 12 are not deformed, and thus firmly grasp the ground, improving the rehabilitation effect and the stability of the building; at the same time, since the middle of the triangular support rings 4 is designed with a hollow structure, it is more convenient for the grouting pipe to be inserted for grouting.

[0027] As Figure 4 shown, rod-shaped metal spines 5 are fixed to the metal anchor rods 12 from top to bottom; and the three metal anchor rods 12 are all evenly fixed with rod-shaped metal spines 5. When the metal anchor rods 12 enter the ground hole, since the rod-shaped metal spines 5 and the metal anchor rods 12 are fixed, the rod-shaped metal spines 5 also enter the hole together with the metal anchor rods 12 and are evenly distributed inside the hole. Subsequently, the grouting pipe is inserted into the grouting hole 13 for grouting, and the grout will wrap the rod-shaped metal spines 5 and solidify; if only relying on the thread of the metal anchor rod 12 and the frictional force of the sidewall soil to enhance the anti-floating ability, the anti-floating effect is not obvious. Through the design of the rod-shaped metal spines 5, after the concrete around the rod-shaped metal spines 5 solidifies, in the case of underground water buoyancy, the rod-shaped metal spines 5 will generate a downward pulling force with the surrounding cement and soil, thereby enhancing the anti-floating effect.

[0028] As Figures 4 to 5As shown, a metal barbed hook 6 is fixedly connected to the bottom of the metal anchor rod 12; and the metal barbed hooks 6 are evenly fixed to the bottoms of the three metal anchor rods 12. When the metal anchor rod 12 enters the ground hole, since the metal barbed hook 6 is fixedly connected to the metal anchor rod 12, the metal barbed hook 6 also enters the hole together with the metal anchor rod 12 and is at the bottom of the metal anchor rod 12. Subsequently, the grouting pipe is inserted into the grouting hole 13 for grouting, and the grout will wrap the metal barbed hook 6 and solidify; through the barbed design of the metal barbed hook 6, after the concrete around the metal barbed hook 6 solidifies, in the case of buoyancy force of underground water, the metal barbed hook 6 will hook the surrounding cement and soil and become an integral body with them. Through the combined action of the rod body metal thorns 5 and the metal barbed hook 6, the anti-floating effect is enhanced secondly, so that the whole anti-floating anchor rod is in a stable state in all directions, and the stability of the building is enhanced.

[0029] During operation, first use a hole drilling machine to open a hole in the ground, and then insert the metal anchor rod 12 into the opened hole on the ground. At this time, the frustum fixed cover 1 is fixed to the ground synchronously, and at the same time, the larger opening of the frustum fixed cover 1 needs to be fitted to the ground. Subsequently, grouting is carried out in the anchor rod hole through the grouting hole 13. At this time, the slurry will enter the opened hole on the ground and submerge the middle part of the metal anchor rod 12. After the slurry solidifies, the fixation of the metal anchor rod 12 to the building can be realized.

[0030] By providing the drainage groove 2, when the frustum fixed cover 1 covers the ground, the liquid diversion of the top of the frustum fixed cover 1 can be realized, and the liquid is transported to a position far from the metal anchor rod 12, reducing the penetration of the liquid at the contact position between the metal anchor rod 12 and the ground. At the same time, the liquid will not be blocked when flowing through the plug cone hole position 21 in the drainage groove 2.

[0031] By providing the metal plug cone 3, when the frustum fixed cover 1 is placed on the ground, the metal plug cone 3 can be aligned with the plug cone hole position 21 and inserted into the ground and fixedly connected to the frustum fixed cover 1, and each plug cone hole position 21 corresponds to a metal plug cone 3, which are evenly distributed on the surface of the frustum fixed cover 1.

[0032] During operation, when the metal anchor rod 12 is inserted into the ground, since the triangular support ring 4 is fixedly connected to the metal anchor rod 12, the triangular support ring 4 enters the hole together with the metal anchor rod 12. Subsequently, the grouting pipe is inserted into the grouting hole 13 for grouting, and the grout will wrap the triangular support ring 4 and solidify.

[0033] When the metal anchor rod 12 enters the ground hole, since the rod body metal thorns 5 are fixedly connected to the metal anchor rod 12, the rod body metal thorns 5 also enter the hole together with the metal anchor rod 12 and are evenly distributed in the hole. Subsequently, the grouting pipe is inserted into the grouting hole 13 for grouting, and the grout will wrap the rod body metal thorns 5 and solidify.

[0034] While the metal anchor rod 12 enters the ground hole, since the metal barbs 6 are fixedly connected to the metal anchor rod 12, the metal barbs 6 also enter the hole together with the metal anchor rod 12 and are at the bottom of the metal anchor rod 12. Subsequently, the grouting pipe is inserted into the grouting hole 13 for grouting, and the grout will wrap the metal barbs 6 and solidify.
