It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0026] Embodiment of the fixing device:

[0027] SeeFigure 1 , which is a schematic structural diagram of the anchor bolt fixing device provided by an embodiment of the present invention. As shown in the figure, the fixing device includes: a wire rack 1, a bolt fixing rack 2, and a positioning disk 3; wherein,

[0028] A first positioning structure 4 is arranged on the wire rack 1 for positioning the positioning disk 3. Specifically, the wire rack 1 is a frame structure for fixing the first positioning structure 4, so as to perform positioning through the positioning disk 3, and the coordinate position of the anchor bolt 5 in the horizontal direction is confirmed through the positioning of the positioning disk 3. The positions of the first positioning structure 4 and the wire rack 1 can be determined according to the actual situation, such as the axis of the foundation stub. The first positioning structure 4 can be a positioning rope or a steel wire, which is placed above the wire rack 1. Weights (not shown in the figure) can be respectively arranged at both ends of the positioning rope or the steel wire to avoid the displacement of the positioning rope, thereby ensuring the accuracy of its position, and further ensuring the accuracy of the positions of the positioning disk 3 and the anchor bolt 5. That is to say, the first positioning structure 4 is equivalent to the reference of the foundation pile, that is, the reference of the pre-positioning position of the anchor bolt 5. Among them, the weights can be heavy hammers or plumb bobs. The wire rack 1 can be located on the top of the foundation or the top of the cushion layer, and the wire rack 1 is installed 50 mm higher than the top of the anchor bolt 5 after installation.

[0029] The bolt fixing rack 2 is arranged below the first positioning structure 4 (relative to Figure 1 the position shown), for supporting the positioning disk 3 and fixing the anchor bolt 5. Specifically, the bolt fixing rack 2 can be a frame structure welded by steel bars for supporting the positioning disk 3. Of course, it can also be other structures, as long as it is determined that its top wall is hollowed out so that the anchor bolt 5 fixed on the positioning disk 3 can extend downward from the top wall of the bolt fixing rack 2. At the same time, after the anchor bolt 5 is positioned through the positioning disk 3, it can be fixed on the bolt fixing rack 2 to avoid the movement of the anchor bolt 5 during pouring, thereby ensuring the accuracy of the position of the anchor bolt 5. After the anchor bolt 5 is positioned, it can be fixed on the bolt fixing rack 2 by welding, such as spot welding, or by setting a fixture (not shown in the figure) on the bolt fixing rack 2 to realize the fixing of the anchor bolt 5.

[0030] A number of bolt holes 31 corresponding to the anchor bolts 5 one by one are arranged on the positioning disk 3 for fixing the anchor bolts 5. Specifically, as Figure 5As shown, to achieve the positioning of the anchor bolts 5, the anchor bolts 5 are inserted through their corresponding bolt holes 31 and fixed to the positioning plate 3 to achieve the relative positioning between multiple anchor bolts 5, so as to meet the accuracy requirements after being embedded and installed on the flange. Among them, the positioning plate 3 can be adapted to the cross-section of the foundation stub pile, so that the bolt holes 31 are adapted to the pre-positioning positions of the anchor bolts 5. The positioning plate 3 can be a plywood formwork for easy hole opening. Of course, it can also be made of other materials, and no limitations are made in this embodiment; the positions of the bolt holes 31 are set in one-to-one correspondence with the anchor bolts 5. After the positioning plate 3 is positioned, the bolt holes 31 are located at the embedded positions of their corresponding anchor bolts 5.

[0031] The positioning plate 3 is arranged on the bolt fixing frame 2 and is located below the first positioning structure 4. A second positioning structure 32 that cooperates with the first positioning structure 4 is arranged on the top wall of the positioning plate 3 to position the positioning plate 3, so as to achieve the positioning of the bolt holes 31 and the anchor bolts 5 in the horizontal plane direction. Specifically, through the cooperation between the first positioning structure 4 and the second positioning structure 32, the positioning plate 3 is positioned, so that the bolt holes 31 are correspondingly arranged at the positions of the anchor bolts 5 embedded in the foundation stub pile, and thus the anchor bolts 5 are positioned to the embedded positions through the bolt holes 31. The second positioning structure 32 can be to draw relevant structures, such as cross lines, on the plywood formwork with tools, etc. See Figure 6 , in this embodiment, the cross-section of the foundation stub pile is square, and four anchor bolts 5 that are arranged symmetrically along the diagonal need to be embedded on it. At this time, to facilitate the positioning of the bolt holes 31, both the first positioning structure 4 and the second positioning structure 32 are cross structures, and the intersection positions thereof correspond to the axis positions of the foundation stub pile, so that it is only necessary to ensure that the cross of the first positioning structure 4 is located within the foundation stub pile to form a "field" structure, and when the second positioning structure 32 cooperates with the first positioning structure 4, they are aligned with each other to ensure the positioning of the bolt holes 31. Of course, for other structures of the foundation stub pile and other positions of its anchor bolts, the first positioning structure 4 and the second positioning structure 32 can be correspondingly set as other structures.

[0032] An adjusting positioning member 6 is arranged on the positioning plate 3 to adjust the position of the anchor bolt 5 in the thickness direction of the positioning plate 3 (such as Figure 1 the height direction shown) and fasten the anchor bolt 5, so as to achieve the positioning and fixing of the anchor bolt 5 in the height direction. Specifically, through the cooperation of the first positioning structure 4 and the second positioning structure 32, the positioning of the horizontal coordinate position of the positioning plate 3 is realized, that is, the positioning of the horizontal coordinates of the bolt holes 31 and the anchor bolts 5 is realized; to facilitate the adjustment of the height position of the anchor bolt 5, the anchor bolt 5 is inserted through the bolt hole 31 that is a connecting through hole, and the height of the anchor bolt 5 is adjusted through the adjusting positioning member 6 to be positioned to the design elevation and the anchor bolt 5 is fastened to the positioning plate 3 through the adjusting positioning member 6.

Among them, the lower fixing cross beam 13 is located at the lower part of the support column 11 to avoid making way for the first positioning structure 4. In this embodiment, two lower fixing cross beams 13 are taken as an example for illustration. The two lower fixing cross beams 13 are arranged in parallel and are respectively connected to two support columns 11 on one side to improve the connection stability between the support columns 11. Of course, the lower fixing cross beam 13 can also be four, so as to form a quadrilateral connected to the support columns 11 around the outer periphery of the four support columns 11. The lower fixing cross beam 13 can also not be provided, that is, the support columns 11 are connected by the upper fixing cross beam 12 to form a whole.

[0035] The four upper fixing cross beams 12 are all arranged at the upper part of the support columns 11, and moreover, the four upper fixing cross beams 12 are respectively and adjustably connected to the positions between two of the support columns 11 to enclose a quadrilateral structure for supporting the first positioning structure 4. Specifically, the four upper fixing cross beams 12 can be arranged in a quadrilateral shape above the lower fixing cross beam 13 and around the outer periphery of the four support columns 11 and are connected to the support columns 11. Preferably, this quadrilateral is arranged at the upper end of the support columns 11 to ensure the stability of the support columns 11. Among them, the upper fixing cross beam 12 is adjustably connected to the support column 11 to facilitate the adjustment of length and height, so that the wire rack 1 can be adjusted according to the foundation short pile and be erected above the bolt fixing rack 2 and the positioning disc 3, and then the first positioning structure 4 can position the positioning disc 3.

[0036] In this embodiment, a vertical support groove is provided on the support column 11 along its length direction, and two horizontal support grooves are provided on the upper fixed cross beam 12 along its length direction. A locking member is provided on each horizontal support groove, and it penetrates through the horizontal support groove and the vertical support groove; the locking member is adjustably connected to the horizontal support groove for adjusting the distance between the two support columns 11 connected by the upper fixed cross beam 12, that is, adjusting the width and length of the wire rack 1; the locking member is adjustably connected to the vertical support groove for adjusting the height position of the connection of the upper fixed cross beam 12, and further adjusting the height of the first positioning structure 4 placed on the upper fixed cross beam 12 so that it is located above the positioning disk 3. Preferably, after the anchor bolt 5 is positioned to the design elevation, the upper fixed cross beam 12 and the first positioning structure 4 are higher than the top of the anchor bolt 5 by a preset distance. In this embodiment, the preset distance can be 50 mm, and of course, it can also be other values.

[0037] In this embodiment, two lower flat support grooves can also be provided on the lower fixed cross beam 13 along its length direction. A locking member is provided on each horizontal support groove, and it penetrates through the lower flat support groove and the vertical support groove; the locking member is adjustably connected to the lower flat support groove for adjusting the distance between the two support columns 11 connected by the lower fixed cross beam 13, that is, adjusting the width and / or length of the wire rack 1; the locking member is adjustably connected to the vertical support groove for adjusting the height position of the connection of the lower fixed cross beam 13. Among them, the locking member is a screw to realize the assembly and fixation of the wire rack 1.

[0038] See Figure 4 , which is a schematic structural diagram of the angle steel used in the wire rack provided by the embodiment of the present invention. As shown in the figure, the support column 11, the lower fixed cross beam 13, and the upper fixed cross beam 12 can all be angle steel structures 15 with a side width of 50 mm and a side thickness of 5 mm. An adjustment groove 151 is opened on one side, and the groove is opened according to the size of the selected fastening screw. The length of the adjustment groove 151 is determined by itself. Fixing the angle steel with screws can facilitate the random adjustment of the length and height.

[0039] See Figure 2 , which is a schematic structural diagram of the bolt fixing frame of the anchor bolt fixing device provided by the embodiment of the present invention. As shown in the figure, the bolt fixing frame 2 includes: at least three fixed columns 21; among them,

[0040] At least three fixed columns 21 are arranged in a polygon, and the tops of any two adjacent fixed columns 21 are connected by a cross beam 22, so that a polygon is formed by enclosing the cross beams 22 to support the positioning plate 3. Specifically, there can be four fixed columns 21 to enclose a rectangle or a square, and there can be six cross beams 22. Four of them are connected into a rectangle or a square at the top of the rectangle or square enclosed by the fixed columns 21 to support the positioning plate 3, so that the positioning plate 3 is placed on the cross beam 22. The other two are inside the rectangle or square for support. Of course, the cross beam 22 can also be other numbers to form a grid structure or other structures, as long as it is ensured that the anchor bolts 5 can pass through the gaps between the cross beams 22. In this embodiment, no limitation is made on it. Among them, the fixed columns 21 and the cross beams 22 can be steel bars and are fixed by welding.

Specifically, the bottom end of the fixed column 21 can be inserted into the soil layer to ensure the stability of the bolt fixing bracket 2. The height of the cross beam 22 and the positioning plate 3 can also be adjusted by adjusting the depth of the fixed column 21 buried in the soil layer. Of course, the fixed column 21 can also be a telescopic rod to facilitate the adjustment of the height.

[0042] See Figure 6 , which is a schematic structural diagram of the fastening between the positioning plate and the anchor bolt of the anchor bolt fixing device provided by the embodiment of the present invention. As shown in the figure, the adjusting positioning member 6 provided on the positioning plate 3 includes two adjusting nuts 61 respectively provided on both sides of the positioning plate 3 (such as Figure 5 the upper and lower sides shown in the figure) for screwing with the anchor bolt 5 to adjust the height position of the anchor bolt 5 and fasten the anchor bolt 5 to the positioning plate 3.

[0043] In summary, for the anchor bolt fixing device provided in this embodiment, through the cooperation between the first positioning structure 4 provided on the wire rack 1 and the second positioning structure 32 on the positioning plate 3, the positioning of the horizontal coordinate position of the positioning plate 3 is realized, that is, the positioning of the coordinates of the bolt hole 31 and the anchor bolt 5 in the horizontal direction is realized.

[0044] Embodiment of construction method:

[0045] Refer to Figure 7 , which is a flow chart of the construction method for fixing anchor bolts provided by the embodiment of the present invention. As shown in the figure, this construction method can be fixed by using the above fixing device. The relevant structures of each component can refer to the embodiment of the fixing device, which will not be elaborated in this embodiment. This construction method includes the following steps:

[0046] Step S1 of making the positioning plate: Make a positioning plate according to the cross-section of the foundation short column, draw a second positioning structure in a cross shape on the positioning plate, and drill holes on the positioning plate to form a number of bolt holes.

[0047] Specifically, first, the positioning plate 3 can be made according to the cross-section of the foundation short column, and its cross-section is the same as and has the same size as that of the foundation short column, so as to be adapted to accurately position the anchor bolt 5; then, according to the position of the embedded anchor bolt 5 on the foundation short column, make a second positioning structure 32 on the positioning plate 3 to be used as a reference line for positioning the positioning plate 3; finally, drill holes on the positioning plate 3 to make a number of bolt holes 31 adapted to the anchor bolt 5 on the bolt positioning drawing, so as to complete the production of the positioning plate 3.

[0048] Step S2 of making the wire frame: Make a wire frame and place the wire frame above the foundation short column, lead the axis of the foundation short column to the top of the wire frame, and set a first positioning structure at the top of the wire frame based on this.

[0049] Specifically, first, make the wire frame 1 through the angle steel structure 15 with a side width of 50 mm and a side thickness of 5 mm. An adjustment groove 151 is opened on one side, and the groove is opened according to the size of the selected fastening screw. The length of the adjustment groove 151 is determined by itself. The angle steel can be fixed with screws to facilitate random adjustment of the length and height, so as to form a frame-shaped wire frame 1 through the assembly of multiple angle steel structures 15; then, install the wire frame 1. The wire frame 1 is located on the top of the foundation or the top of the cushion, and the wire frame 1 is installed 50 mm higher than the top of the anchor bolt 5; finally, after the wire frame 1 is fixed, use an instrument to lead the axis of the foundation short pile to the top of the wire frame 1, and set a first positioning structure 4 at the corresponding position at the top of the wire frame 1 for positioning the anchor bolt 5 and the positioning plate 3. The wire frame 1 can be removed in time after use and can be reused.

[0050] Step S3 of making the bolt fixing frame: Make a bolt fixing frame and fix it below the first positioning structure.

[0051] Specifically, after the wire frame 1 is installed, steel bars can be welded into a bolt fixing frame 2 with a frame structure, and the frame can be fixed below the first positioning structure 4, and can be erected or inserted on the soil layer or the working surface. The fixing columns 21 and the crossbeams 22 of the bolt fixing frame 2 are both steel bars, and are welded together to form the bolt fixing frame 2. The diameter of the steel bars can be 12 mm to 16 mm.

[0052] Positioning plate positioning step S4, placing the positioning plate on the bolt fixing frame, and matching the second positioning structure with the first positioning structure to position the positioning plate, so as to achieve positioning of the bolt holes and the anchor bolts along the horizontal plane direction.

[0053] Specifically, the positioning plate 3 is stably placed on the upper part of the bolt fixing frame 2, and the second positioning structure 32 is matched with the first positioning structure 4 to accurately position the positioning plate 3, so that the position of the bolt hole 31 is then positioned to the corresponding position of the pre-buried anchor bolt 5 on the foundation. Among them, the first positioning structure 4 can be a cross line formed by two steel wire ropes, and the second positioning structure 32 is a cross line drawn on the positioning plate 3; by aligning the cross line on the positioning plate 3 with the cross line of the steel wire combination on the wire frame 1, the positioning plate 3 is positioned and stably placed on the upper part of the bolt fixing frame 2.

[0054] Bolt tightening step S5, insert each anchor bolt into the corresponding bolt hole from the bottom of the positioned positioning plate, adjust the position of the anchor bolt along the thickness direction of the positioning plate until the preset elevation by adjusting the positioning piece, and tighten the anchor bolt by adjusting the positioning piece to fix the anchor bolt to the positioning plate.

[0055] Specifically, first, insert the pre-buried anchor bolt 5 from the bottom into the corresponding bolt hole 31 on the positioning plate 3; then, adjust the anchor bolt 5 along the thickness direction of the positioning plate 3 (such as Figure 1 The anchor bolt 5 is adjusted to the position in the height direction shown in the figure until the preset elevation is reached, and the anchor bolt 5 is tightened by adjusting the positioning member 6 to fix the anchor bolt 5 to the positioning plate 3; the adjusting nut 61 arranged on the lower side of the positioning plate 3 can be installed on the anchor bolt 5 first, and then the bottom of the positioning plate 3 is leveled with the adjusting nut 61 so that the anchor bolt 5 is adjusted to the designed elevation, and the top of the positioning plate 3 is fixed with the adjusting nut 61 to fix the anchor bolt 5 firmly. Among them, the preset elevation is the same as the designed elevation, which can be determined according to actual conditions.

[0056] Bolt fixing step S6, after the anchor bolts are fixed to the positioning plate, the anchor bolts are fixed to the bolt fixing frame to avoid misalignment of the anchor bolts during pouring.

[0057] Specifically, first, after the anchor bolts 5 are fixed on the positioning plate 3, the anchor bolts 5 can be spot-welded to the bolt fixing bracket 2 with steel bars having a diameter of 12 mm to 16 mm.

[0058] Pouring step S7: After the bolts are fixed to the bolt fixing bracket, pour concrete. After the concrete is formed, remove the adjusting positioning member and the positioning plate for reuse.

[0059] Specifically, first, pour concrete; then, after the concrete pouring is completed, remove the adjusting nut 61 and the positioning plate 3 for reuse. Pay attention to the protection of the finished products of the adjusting nut 61 and the positioning plate 3 to avoid damage and affect the next use.

[0060] Among them, there is no sequence requirement among the positioning plate manufacturing step S1, the wire rack manufacturing step S2, and the bolt fixing bracket manufacturing step S3.

[0061] See Figure 8 , which is the flow chart of the positioning plate manufacturing step provided by the embodiment of the present invention. As shown in the figure, the positioning plate manufacturing step S1 includes the following sub-steps:

[0062] Sub-step S11 of plate manufacturing: Use a wood-bonded template to make a positioning plate with the template made to fit the cross-sectional size of the foundation short column.

[0063] Specifically, the positioning plate 3 is made of a 15-mm-thick wood-bonded template, and the template is made into a positioning plate that fits the cross-sectional size of the foundation short column.

[0064] Sub-step S12 of the second positioning structure: Use a blade to draw a cross line on the made template as the second positioning structure.

[0065] Specifically, use a blade or other tool to draw a cross line on the made template as the second positioning structure 32.

[0066] Sub-step S13 of hole opening: According to the bolt positioning drawing, draw a bolt positioning cross line on the positioning plate, draw a circle at the drawn positioning center according to the bolt diameter required by the drawing design, and then drill holes on the drawn circle to form bolt holes.

[0067] Specifically, first, draw a bolt positioning cross line, i.e., the bolt positioning center, on the positioning plate 3 according to the bolt positioning drawing; then, draw a circle at the drawn positioning center according to the bolt diameter required by the drawing design; finally, drill holes on the drawn circle to form bolt holes 31, and the bolt positioning plate manufacturing is completed.

[0068] See Figure 9 , which is the flow chart of the wire rack manufacturing step provided by the embodiment of the present invention. As shown in the figure, the wire rack manufacturing step S2 includes the following sub-steps:

[0069] Wire rack manufacturing sub-step S21: Groove one side of the angle steel to manufacture a wire rack using the grooved angle steel and fastening screws.

[0070] Specifically, first, determine the height, length, and width of the wire rack 1 based on the pre-positioned height of the top of the anchor bolt 5 and the cross-section of the foundation short column, that is, determine the lengths of the support columns 11, the upper fixed cross beam 12, and the lower fixed cross beam 13, and cut accordingly to obtain four support columns 11, four upper fixed cross beams 12, and two lower fixed cross beams 13. Then, groove one side or both sides of each cut angle steel as an adjustment groove 151 according to the diameter of the selected fastening screw. For example, the support columns 11 and the upper fixed cross beam 12 need to be grooved on both sides, while the lower fixed cross beam 13 only needs to be grooved on one side. Finally, manufacture the wire rack 1 using the grooved angle steel and fastening screws, that is, assemble the four support columns 11, four upper fixed cross beams 12, and two lower fixed cross beams 13 according to the structure in the fixed device embodiment and fix them with fastening screws.

[0071] Wire rack positioning sub-step S22: Place the manufactured wire rack on the top of the foundation or the top of the cushion layer, with the wire rack being 50 mm higher than the top of the anchor bolt.

[0072] Specifically, first, place the manufactured wire rack 1 on the top of the foundation or the top of the cushion layer, with the wire rack 1 being 50 mm higher than the pre-positioned top of the anchor bolt 5 to avoid interference between the wire rack 1 and the fixing of the anchor bolt 5.

[0073] First positioning structure sub-step S23: After the wire rack is fixed, use an instrument to lead the axis of the foundation onto the top of the wire rack, and then fix a steel wire at the top of the wire rack as the first positioning structure, and hang plumb bobs or plumb lines at both ends of the steel wire.

[0074] Specifically, after the wire rack 1 is fixed, use an instrument to lead the axis of the foundation onto the top of the wire rack 1, and then fix a steel wire at the top of the wire rack 1 as the first positioning structure 4, and plumb bobs or plumb lines can be hung at both ends of the steel wire as counterweights.

[0075] In summary, for the construction method of fixing anchor bolts provided in this embodiment, through the cooperation between the first positioning structure 4 provided on the wire rack 1 and the second positioning structure 32 on the positioning disk 3, the positioning of the coordinate position of the positioning disk 3 in the horizontal direction is realized, that is, the positioning of the coordinate of the bolt hole 31 and the anchor bolt 5 in the horizontal direction is realized. Furthermore, according to the positioned position, it is placed on the bolt fixing rack 2 to realize the positioning and fixing of the coordinate of the positioning disk 3 in the horizontal direction, thereby realizing the positioning of the coordinate of the anchor bolt 5 in the horizontal direction; through the adjustment positioning member 6 on the positioning disk 3, the position of the anchor bolt 5 in the thickness direction of the positioning disk 3 is adjusted, that is, the height of the anchor bolt 5 is adjusted to the design elevation by adjusting the positioning member 6, and the anchor bolt 5 is fastened to the positioning disk 3 by adjusting the positioning member 6, thereby realizing the positioning and fixing of the anchor bolt 5. This construction method facilitates the positioning of the anchor bolt 5, and moreover, the construction is simple, easy to adjust and position, ensuring the accuracy of the position of the anchor bolt 5.
