Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of pre-embedded anchor bolts for rubber dams, specifically a welding mold for pre-embedded bolts for rubber dams. Background Technology

[0002] During the installation of pre-embedded anchor bolts for rubber dams, the earliest installation method involved first installing the pre-embedded plate, and then installing the pre-embedded bolts one by one onto the plate. This method had the lowest precision and efficiency, and the distance between each pre-embedded bolt and the rubber dam baseline was prone to cumulative errors. Since a significant portion of the pre-embedded plates were cast, the position and diameter errors of the holes on the plates were substantial. Furthermore, due to limitations in the manufacturing process, the lower part of the pre-embedded bolts was prone to bending, causing significant deviations in the position of the bolt tops. Also, some holes on the pre-embedded plates were oversized. These two factors frequently resulted in significant errors in the planar position of the pre-embedded bolts when installing the pressure plate, leading to misalignment with the holes on the pressure plate. This reduced efficiency and quality during manufacturing and installation, sometimes even necessitating the enlargement of the pressure plate holes during installation. The perpendicularity error between the bottom surface of the clamping nut on the pre-embedded bolt and the thread axis also caused the pre-embedded bolt to be non-perpendicular to the pre-embedded plate, amplifying into a deviation in the position of the bolt top. Rubber dam embedded plates are generally not thick. Slight warping of the embedded plate's flatness, including deformation caused by spot welding on the back of the embedded plate, can be amplified into a shift in the position of the top of the embedded bolt. Utility Model Content

[0003] The purpose of this utility model is to provide a welding mold for pre-embedded bolts in rubber dams.

[0004] A welding mold for pre-embedded bolts in a rubber dam includes a triangular prism mounting base. A base plate is fixedly installed on the lower part of one side of the triangular prism mounting base. A lower limiting plate is fixedly installed on the upper part of the base plate. A plurality of lower limiting holes are evenly opened on the lower limiting plate. Fixing blocks are fixedly installed on both sides of the top surface of the lower limiting plate. A middle limiting plate is fixedly installed on the top of the two fixing blocks. A plurality of middle limiting holes that mate with the lower limiting holes are evenly opened on the middle limiting plate. An upper limiting plate is installed above the middle limiting plate. The upper limiting plate is fixedly connected to the side of the triangular prism mounting base. A plurality of semi-circular limiting grooves that mate with the middle limiting holes are opened on the side of the upper limiting plate away from the triangular prism mounting base.

[0005] Furthermore, the cross-section of the triangular prism mounting base is an acute-angled triangle.

[0006] In summary, this utility model has the following beneficial effects:

[0007] This invention ensures that the bolt portions of the embedded bolts below the embedded plate are of uniform length. The lower limiting hole, middle limiting hole, and semi-circular limiting groove respectively mate with the corresponding positions of the embedded bolts, ensuring the perpendicularity of the embedded bolts to the embedded plate. The embedded plate, which contacts and mates with the middle limiting plate, effectively prevents deformation of the embedded plate. The triangular prism mounting base has an acute-angled triangular cross-section, which ensures that the bending directions of the upper ends of multiple embedded bolts are consistent, facilitating the welding and installation of the rubber dam embedded bolts.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described as follows:

[0015] A welding mold for pre-embedded bolts of a rubber dam includes a triangular prism mounting base 1. A base plate 2 is fixedly installed on the lower part of one side of the triangular prism mounting base 1. A lower limiting plate 3 is fixedly installed on the upper part of the base plate 2. A plurality of lower limiting holes 4 are evenly opened on the lower limiting plate 3. Fixing blocks 5 are fixedly installed on both sides of the top surface of the lower limiting plate 3. The top of the two fixing blocks 5 is fixedly installed with the same middle limiting plate 6. A plurality of middle limiting holes 7 that cooperate with the lower limiting holes 4 are evenly opened on the middle limiting plate 6. An upper limiting plate 8 is installed above the middle limiting plate 6. The upper limiting plate 8 is fixedly connected to the side of the triangular prism mounting base 1. A plurality of semi-circular limiting grooves 9 that cooperate with the middle limiting holes 7 are opened on the side of the upper limiting plate 8 away from the triangular prism mounting base 1.

[0016] In this embodiment, there are no through holes on the base plate 2. The number and center distance of the multiple lower limit holes 4 on the lower limit plate 3, the multiple middle limit holes 7 on the middle limit plate 6, the multiple semi-circular limit grooves 9 on the upper limit plate 8, and the multiple embedded bolt holes 11 on the embedded plate 10 are the same. The base plate 2 is in contact with the lower end face of the embedded bolt 12. The lower end of the embedded bolt 12 is movably disposed in the lower limit hole 4, the middle part of the embedded bolt 12 is movably disposed in the middle limit hole 7, and the upper part of the embedded bolt 12 is movably disposed in the semi-circular limit groove 9. Preferably, the diameter of the corresponding position of the embedded bolt 12 is slightly smaller than that of the lower limit hole 4, the middle limit hole 7, and the semi-circular limit groove 9.

[0017] like Figure 3 As shown, when using this utility model, the embedded plate 10 is first placed on top of the middle limiting plate 6. The embedded plate 10 is then moved so that the multiple embedded plate bolt holes 11 on the embedded plate 10 are aligned with the corresponding middle limiting holes 7. The lower ends of the embedded bolts 12 are then inserted sequentially into the embedded plate bolt holes 11, the middle limiting holes 7, and the lower limiting holes 4, so that the lower end face of the embedded bolts 12 contacts the base plate 2, and the upper part of the embedded bolts 12 is located in the semi-circular limiting groove 9. At this time, the bolt portions of the embedded bolts 12 below the embedded plate 10 are of the same length, and the lower limiting holes 4, the middle limiting holes 7, and the semi-circular limiting grooves 9 respectively cooperate with the corresponding positions of the embedded bolts 12 to ensure the perpendicularity of the embedded bolts 12 to the embedded plate 10.

[0018] When the operator uses electric welding to spot weld the embedded plate 10 and the embedded bolt 12 together, the embedded plate 10, which is in contact with the middle limit plate 6, can effectively prevent the embedded plate 10 from deforming.

[0019] In this embodiment, preferably, the cross-section of the triangular prism mounting base 1 is an acute-angled triangle. For example... Figure 3As shown, when the pre-embedded bolt 12 is installed in the welding mold of the rubber dam pre-embedded bolt of this utility model, the pre-embedded bolt 12 is inclined to the ground, and the bent part at the upper end of the pre-embedded bolt 12 is inclined to the left. Under the action of gravity, the bent part at the upper end of the pre-embedded bolt 12 drives the entire pre-embedded bolt 12 to rotate, and the bent part at the upper end of the pre-embedded bolt 12 is oriented to the left. The bent parts at the upper ends of multiple pre-embedded bolts 12 are in the same direction, which facilitates the welding and installation of the rubber dam pre-embedded bolts.

[0020] In summary, this utility model is not limited to the specific embodiments described above. Those skilled in the art can make various modifications and alterations without departing from the spirit and scope of this utility model. The scope of protection of this utility model should be determined by the claims of this utility model.
