Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and in particular to a correction device for solving the problem of dimensional deviations in anchor bolts. Background Technology

[0002] Passive protection systems are a lightweight protection method commonly used to address landslides and rockfalls in engineering projects. They offer advantages such as high protection levels, good protection effects, quick installation, and low engineering costs, and have been widely promoted and applied in numerous mountain-side roads, including highways, railways, and scenic tourist routes.

[0003] In passive protection systems, the protective netting is installed on uprights, which are then fixed to anchor bolts pre-embedded in the mountainside via bases. During base installation, issues often arise due to insufficient anchor bolt embedding precision, hindering successful installation. Specifically, when anchor bolt anchoring deteriorates (e.g., distance errors, lack of verticality), the holes in the base may not align with the anchor bolts, preventing proper installation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a correction device for solving the problem of dimensional deviation of anchor rods, so as to ensure that the base can be installed smoothly when there is dimensional deviation of anchor rods.

[0006] The first connecting structure is provided with two first anchor holes, which are respectively used to cooperate with two of the pre-embedded anchor bolts;

[0007] The second connecting structure is provided with two second anchor holes, which are respectively used to cooperate with two other pre-embedded anchor bolts;

[0008] The base plate has mounting bolts on its upper surface for mounting a base connected to it; and the base plate can be fixedly connected to both the first connecting structure and the second connecting structure at the same time.

[0009] Furthermore, both the first anchor bolt hole and the second anchor bolt hole are straight slot holes that are adapted to the outer diameter of the anchor bolt and can provide adjustment margin.

[0010] Furthermore, after the two first anchor bolt holes are respectively engaged with two of the pre-embedded anchor bolts, the first connecting structure is locked and fixed to the anchor bolts by nuts;

[0011] After the two second anchor bolt holes are respectively matched with the other two pre-embedded anchor bolts, the second connecting structure is also locked and fixed to the anchor bolts by nuts.

[0012] Furthermore, the base plate is fixedly connected to the first connecting structure by a first fixing bolt, and fixedly connected to the second connecting structure by a second fixing bolt.

[0013] Furthermore, the first connecting structure is provided with a first adjustment hole;

[0014] The second connecting structure is provided with a second adjustment hole;

[0015] The base plate is provided with a third adjustment hole corresponding to the first adjustment hole and a fourth adjustment hole corresponding to the second adjustment hole;

[0016] After the first fixing bolt passes through both the first adjusting hole and the third adjusting hole, the base plate is fixedly connected to the first connecting structure by means of the connection between the nut and the first fixing bolt.

[0017] After the second fixing bolt passes through both the second adjusting hole and the fourth adjusting hole, the base plate is fixedly connected to the second connecting structure by means of the connection between the nut and the second fixing bolt.

[0018] Furthermore, the number of the first adjustment holes is two, and they are set at a predetermined distance apart;

[0019] The second adjustment hole is also two in number and is set at a predetermined distance apart;

[0020] The base plate is provided with two third adjustment holes corresponding to the two first adjustment holes, and two fourth adjustment holes corresponding to the two second adjustment holes.

[0021] There are two of each of the first fixing bolts and the second fixing bolts.

[0022] Furthermore, the first adjusting hole is a straight slot hole that matches the outer diameter of the first fixing bolt and provides an adjustment margin, and the second adjusting hole is a straight slot hole that matches the outer diameter of the second fixing bolt and provides an adjustment margin.

[0023] Furthermore, the adjustment margin provided by the first adjustment hole for the first fixing bolt and the adjustment margin provided by the second adjustment hole for the second fixing bolt are parallel or approximately parallel to each other in the adjustment direction.

[0024] Furthermore, the third adjusting hole is a straight slot hole that matches the outer diameter of the first fixing bolt and provides an adjustment margin, and the fourth adjusting hole is a straight slot hole that matches the outer diameter of the second fixing bolt and provides an adjustment margin.

[0025] Furthermore, the adjustment margin provided by the first adjustment hole for the first fixing bolt and the adjustment margin provided by the third adjustment hole for the first fixing bolt are perpendicular or approximately perpendicular to each other in the adjustment direction; the adjustment margin provided by the second adjustment hole for the second fixing bolt and the adjustment margin provided by the fourth adjustment hole for the second fixing bolt are also perpendicular or approximately perpendicular to each other in the adjustment direction.

[0026] Furthermore, the first connecting structure has a first notch at the bottom of the first adjusting hole to provide space for the cap of the first fixing bolt to be hidden there;

[0027] The second connecting structure has a second notch at the bottom of the second adjusting hole to provide space for the cap of the second fixing bolt to be concealed there.

[0028] Furthermore, the number of mounting bolts is four, and they are vertically fixed near the four corners of the upper surface of the base plate.

[0029] In existing technologies, during the construction of a passive protection system, anchor bolts are pre-embedded at the locations where columns will be installed. When installing the columns, a base is first installed at the anchor bolt location, and then the column is installed on the base. However, due to potential distance errors or non-perpendicularity issues during the pre-embedding of the anchor bolts, the holes on the base may not align perfectly with the anchor bolts, making it difficult to install the base smoothly. To address this, the correction device of this invention can be used to ensure the smooth installation of the base.

[0030] Specifically, in using this invention, firstly, the first connecting structure is fixed to two of the anchor rods, and simultaneously, the second connecting structure is fixed to the other two anchor rods. Then, the base plate is simultaneously fixed to both the first and second connecting structures. After the base plate is fixed, since mounting bolts are provided at its top, and the positions of these bolts are fixed and match the holes on the base, the base can be directly installed onto the mounting bolts on the base plate. Subsequently, the columns can be installed on the base.

[0031] In the above process, the first and second connecting structures are directly connected to the anchor rods. Each connecting structure can only connect to two anchor rods simultaneously, and the connecting holes are straight slots. Therefore, if the anchor rods have a certain distance error or are not perpendicular, adjustments can be made through the first anchor hole of the first connecting structure or the second anchor hole of the second connecting structure to ensure a smooth connection. After the first and second connecting structures are matched and connected to the anchor rods, non-parallelism may occur. Therefore, a base plate is added, allowing the base to be installed on it. When the base plate is connected to the first or second connecting structure, the connecting holes are all straight slots, and the adjustment allowances are perpendicular to each other. Therefore, during base plate installation, adjustments can be made through the first, second, third, and fourth adjustment holes to ensure smooth installation.

[0032] Therefore, this invention can correct the anchor rods when there are dimensional deviations in the pre-embedded anchor rods. The corrected position corresponds to the position of the four mounting bolts on the upper surface of the base plate, thus ensuring the smooth installation of the base and consequently the installation of the column. This solves the problem of difficulty in installing the base due to low pre-embedding accuracy of the anchor rods. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0038] See Figures 1 to 4 This utility model provides a correction device for solving the dimensional deviation of the anchor rod, which includes: a first connecting structure 100, a second connecting structure 200 and a base plate 300.

[0039] The first connecting structure 100 is provided with two first anchor bolt holes 110, which are respectively used to cooperate with two of the pre-embedded anchor bolts.

[0040] The second connecting structure 200 is provided with two second anchor bolt holes 210, which are respectively used to cooperate with two other pre-embedded anchor bolts.

[0041] The upper surface of the base plate 300 is provided with mounting bolts 310 for mounting a base connected to the base plate 300. The base plate 300 can be simultaneously fixedly connected to both the first connecting structure 100 and the second connecting structure 200.

[0042] Typically, there are four mounting bolts 310, which are vertically fixed near the four corners of the upper surface of the base plate 300.

[0043] Preferably, both the first anchor bolt hole 110 and the second anchor bolt hole 210 are straight slot holes that are adapted to the outer diameter of the anchor bolt and can provide adjustment margin.

[0044] The aforementioned straight slotted hole refers to a hole with a certain length and arc-shaped end faces on both sides. When used with bolts, the straight slotted hole, compared to a circular hole, has a certain adjustment margin in the length direction, thus allowing for a certain range of dimensional errors.

[0045] The two first anchor bolt holes 110 are respectively engaged with two of the pre-embedded anchor bolts, and the first connecting structure 100 is locked and fixed to the anchor bolts by nuts. The two second anchor bolt holes 210 are respectively engaged with the other two pre-embedded anchor bolts, and the second connecting structure 200 is also locked and fixed to the anchor bolts by nuts.

[0046] Specifically, when the first connecting structure 100 is connected to the anchor rod, the two anchor rods pass through the two first anchor rod holes 110 of the first connecting structure 100, and then nuts are screwed into the top of the anchor rods to lock and fix the first connecting structure 100 to the anchor rods. Similarly, when the second connecting structure 200 is connected to the anchor rod, the two anchor rods pass through the two second anchor rod holes 210 of the second connecting structure 200, and then nuts are screwed into the top of the anchor rods to lock and fix the second connecting structure 200 to the anchor rods. The first anchor rod holes 110 and the second anchor rod holes 210 are designed as straight slots to provide adjustment margin, ensuring that even if the pre-embedded anchor rod has a certain precision error, the first connecting structure 100 or the second connecting structure 200 can be smoothly connected to it.

[0047] Preferably, the base plate 300 is fixedly connected to the first connecting structure 100 by a first fixing bolt 400, and fixedly connected to the second connecting structure 200 by a second fixing bolt 500.

[0048] Specifically, the first connecting structure 100 is provided with a first adjusting hole 120; the second connecting structure 200 is provided with a second adjusting hole 220; the base plate 300 is provided with a third adjusting hole 320 corresponding to the first adjusting hole 120 and a fourth adjusting hole 330 corresponding to the second adjusting hole 220; the first fixing bolt 400 passes through both the first adjusting hole 120 and the third adjusting hole 320, and is then fixedly connected to the base plate 300 and the first connecting structure 100 by means of a nut connecting to the first fixing bolt 400; the second fixing bolt 500 passes through both the second adjusting hole 220 and the fourth adjusting hole 330, and is then fixedly connected to the base plate 300 and the second connecting structure 200 by means of a nut connecting to the second fixing bolt 500.

[0049] Furthermore, the number of the first adjustment holes 120 is two and they are set at a predetermined distance apart; the number of the second adjustment holes 220 is also two and they are set at a predetermined distance apart; the base plate 300 is provided with two third adjustment holes 320 corresponding to the two first adjustment holes 120, and two fourth adjustment holes 330 corresponding to the two second adjustment holes 220; the number of the first fixing bolt 400 and the second fixing bolt 500 is two each.

[0050] The first adjusting hole 120 is a straight slot that matches the outer diameter of the first fixing bolt 400 and provides adjustment margin, and the second adjusting hole 220 is a straight slot that matches the outer diameter of the second fixing bolt 500 and provides adjustment margin. Furthermore, the adjustment margin provided by the first adjusting hole 120 for the first fixing bolt 400 and the adjustment margin provided by the second adjusting hole 220 for the second fixing bolt 500 are parallel or approximately parallel to each other in the adjustment direction.

[0051] For example, see Figure 2 The first adjusting hole 120 provides adjustment allowance to the first fixing bolt 400 in the x direction, and the second adjusting hole 220 provides adjustment allowance to the second fixing bolt 500 in the x direction as well. The two are parallel or approximately parallel to each other.

[0052] Furthermore, the third adjusting hole 320 is a straight slot hole that matches the outer diameter of the first fixing bolt 400 and provides adjustment margin, and the fourth adjusting hole 330 is a straight slot hole that matches the outer diameter of the second fixing bolt 500 and provides adjustment margin. The adjustment margin provided by the first adjusting hole 120 for the first fixing bolt 400 and the adjustment margin provided by the third adjusting hole 320 for the first fixing bolt 400 are perpendicular or substantially perpendicular to each other in the adjustment direction; similarly, the adjustment margin provided by the second adjusting hole 220 for the second fixing bolt 500 and the adjustment margin provided by the fourth adjusting hole 330 for the second fixing bolt 500 are also perpendicular or substantially perpendicular to each other in the adjustment direction.

[0053] For example, see Figure 2 The first adjusting hole 120 provides adjustment allowance to the first fixing bolt 400 in the x-direction, and the third adjusting hole 320 provides adjustment allowance to the first fixing bolt 400 in the y-direction. The two are perpendicular or approximately perpendicular to each other. The second adjusting hole 220 provides adjustment allowance to the second fixing bolt 500 in the x-direction, and the fourth adjusting hole 330 provides adjustment allowance to the second fixing bolt 500 in the y-direction. The two are perpendicular or approximately perpendicular to each other.

[0054] In a preferred embodiment of this utility model, the first connecting structure 100 has a first notch 130 at the bottom of the first adjusting hole 120 to provide space for the cap of the first fixing bolt 400 to be concealed therein. The second connecting structure 200 has a second notch 230 at the bottom of the second adjusting hole 220 to provide space for the cap of the second fixing bolt 500 to be concealed therein.

[0055] In use, the first connecting structure 100 is first fixed to two anchor rods (not shown in the figure), and the second connecting structure 200 is simultaneously fixed to the other two anchor rods (not shown in the figure). Then, the base plate 300 is fixedly connected to both the first connecting structure 100 and the second connecting structure 200. After the base plate 300 is fixed, since its top is equipped with mounting bolts 310, and the positions of the mounting bolts 310 are fixed and match the holes on the base (not shown in the figure), the base can be directly installed onto the mounting bolts 310 of the base plate 300. Subsequently, columns (not shown in the figure) can be installed on the base.

[0056] In the above process, the first connecting structure 100 and the second connecting structure 200 are directly connected to the anchor rods. The first connecting structure 100 or the second connecting structure 200 can only be connected to two anchor rods simultaneously, and the connecting holes are straight slot holes. Therefore, if there is a certain distance error or non-perpendicularity of the anchor rods, it can be adjusted and corrected through the first anchor rod hole 110 of the first connecting structure 100 or the second anchor rod hole 210 of the second connecting structure 200 to ensure that the first connecting structure 100 or the second connecting structure 200 can be smoothly connected to the anchor rods. After the first connecting structure 100 and the second connecting structure 200 are matched and connected to the anchor rods, non-parallelism may inevitably occur. Therefore, the aforementioned base plate 300 is added, allowing the base to be installed on the base plate 300. When the base plate 300 is connected to the first connecting structure 100 or the second connecting structure 200, the holes connecting the two are straight slot holes and the direction of the adjustment allowance is perpendicular to each other. Therefore, when installing the base plate 300, the base plate 300 can be adjusted and corrected through the first adjustment hole 120, the second adjustment hole 220, the third adjustment hole 320 and the fourth adjustment hole 330 to ensure that the base plate 300 can be installed smoothly.

[0057] Therefore, this invention can correct the anchor rods when there are dimensional deviations in the pre-embedded anchor rods. The corrected position corresponds to the position of the four mounting bolts 310 on the upper surface of the base plate, thus ensuring the smooth installation of the base and consequently the installation of the column. This solves the problem of difficulty in installing the base due to low pre-embedding accuracy of the anchor rods.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
