Description

Technical Field

[0001] The present application relates to the field of fastening tools, and in particular to a T-head bolt sleeve anchor box. Background Art

[0002] Many types of bolts are commonly used to secure industrial equipment foundations. T-head bolt sleeve anchor boxes are widely used due to their high load-bearing capacity, tensile strength, and good seismic performance. The widely used T-head bolt sleeve anchor box consists of a T-head bolt and a sleeve anchor box. The sleeve anchor box includes an anchor box box, an anchor plate, and a sleeve. The anchor plate is provided with a through slot corresponding to the T-head of the T-head bolt, and a torsion block is welded around the through slot. The T-head bolt consists of a T-head and a screw rod, with the T-head being in a straight line shape. When using the T-head bolt to secure ground equipment, the T-head of the T-head bolt penetrates the anchor plate and penetrates into the anchor box box. The T-head then rotates until it is perpendicular to the through slot to hook onto the anchor plate. The torsion block then engages the T-head of the T-head bolt, preventing it from rotating. A portion of the screw rod of the T-head bolt is exposed above the ground. A nut and a washer are used to connect the ground equipment to the screw rod, thereby securing the ground equipment to the ground.

[0003] During the construction of industrial equipment foundations, sleeve anchor boxes for T-head bolts must be installed in designated locations before concrete is poured to secure them. However, during fabrication, the torsion blocks on the anchor plates can easily be welded incorrectly. This prevents the blocks from restricting the rotation of the T-head bolts, preventing them from hooking onto the anchor plates and, consequently, preventing the equipment from being secured to the ground. This error is typically only discovered during foundation inspection after concrete pouring. Resolving this issue is time-consuming and costly, delaying the entire project schedule and compromising the effectiveness of the T-head bolts. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a T-head bolt sleeve anchor box, comprising a T-head bolt, a sleeve anchor box and two limit blocks. The T-head bolt comprises a T-head and a screw, and the T-head is in a straight line shape. The limit block is wedge-shaped, comprising a narrow end and a wide end. The sleeve anchor box comprises an anchor box box, an anchor plate and a sleeve, the anchor plate is fixed to the upper part of the anchor box box, and forms a cavity with the anchor box box, the sleeve is fixed to the upper part of the anchor plate, and a through groove corresponding to the T-head is provided on the anchor plate, and the through groove is connected to the cavity. The T-head is placed in the cavity, and the screw passes through the through groove. When the T-head is perpendicular to the through groove, the two limit blocks are placed in the through groove, with their narrow ends facing downward, respectively located on both sides of the T-head, so that the T-head cannot rotate, and the ground equipment can be connected to the T-head bolt to fix the ground equipment on the ground.

[0005] In some embodiments of the present application, the T-head bolt sleeve anchor box also includes an installation tool for installing the limit block. The wide end of the limit block is provided with a connecting structure corresponding to the installation tool. Using this installation tool for installation can conveniently install the limit block into a sleeve anchor box with a narrow space.

[0006] In some embodiments of the present application, the T-head bolt sleeve anchor box also includes a pad, which is arranged on the top of the sleeve, and the upper surface of the pad is flush with the ground. Adding this pad can improve the bearing capacity of the T-head bolt sleeve anchor box and make the connection between the equipment and the ground more stable.

[0007] In some embodiments of the present application, the limit block has a slope and a plane. In order to adapt to the installation needs of T-head bolts with specifications of M16~M64, the length of the plane is preferably 80~200mm, the slope of the slope is preferably 1:10~1:20, and the surface roughness is below 12.5. At this time, the smooth installation of the limit block can be guaranteed, and the free rotation angle of the T-head bolt will not be too large due to excessive gap, affecting its use.

[0008] The beneficial effects of this application: Compared with the prior art, the utility model adopts a separately installed limit block to limit the rotation of the T-head bolt, which has low production cost, convenient installation, and is not prone to errors during production and installation, which can greatly reduce construction costs and improve construction efficiency.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other alternative implementations obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] Depend on Figure 1 The cross-sectional view shown and Figure 2 As shown in the three-dimensional view of Figure 3, this T-head bolt sleeve anchor box includes a T-head bolt 3, a sleeve anchor box 2, and two stoppers 5. The sleeve anchor box 2 includes a sleeve 21, an anchor plate 22, and an anchor box 23. The anchor plate 22 is fixed to the upper portion of the anchor box 23, forming a cavity 24 with the anchor box. The sleeve 21 is fixed to the upper portion of the anchor plate 22. The anchor plate 22 has a through slot 221 corresponding to the T-head 32 of the T-head bolt 3 and communicating with the cavity 24. The T-head bolt 3 includes a T-head 32 and a screw 31. The T-head 32 is in a straight line shape. The stoppers 5 include a wide end 51 and a narrow end 52. When securing the ground device 6 with the T-head bolt 3, the T-head 32 passes through the through slot 221 on the anchor plate 22 and penetrates into the cavity 24 of the anchor box 23. The screw rod 31 extends upward from the ground. The T-head 32 is then rotated until it is perpendicular to the through slot 221. The stopper 5 is inserted into the through slot 221, locking the T-head 32 and preventing it from rotating. The ground device 6 is now secured to the ground with the T-head bolt 3.

[0021] Figure 4AThe present invention shows an installation tool 7 for installing a limit block 8. The installation tool 7 comprises a handle 71 and an installation rod 72. The installation rod 72 is in the shape of an elongated rod, one end of which is connected to the handle 71, and the other end is cylindrical. A mounting thread 721 is provided on the outer cylindrical surface of the installation tool 72, and the connection structure is a threaded hole 811 corresponding to the mounting thread 721. When installing the limit block 8 into the sleeve anchor box 2, the mounting thread 721 of the installation tool 7 is first screwed into the threaded hole 811 of the limit block 8. Then, the installation tool 7 is held and the limit block 8 is inserted into the through slot 221. The installation tool 7 is rotated in the opposite direction to release the connection between the installation tool 7 and the limit block 8, thereby completing the installation of the limit block 8.

[0022] Figure 4B Another installation tool 9 for installing the limit block 10 is shown. The installation tool 9 includes a handle 91 and a mounting rod 92. The mounting rod 92 is a long rod with one end connected to the handle 91 and the other end provided with a threaded hole 921 along the axial direction. The connection structure provided on the end surface of the wide end 101 of the limit block 10 is a protruding stud 102, which matches the threaded hole 921. The process of installing the limit block 10 to the sleeve anchor box 2 is the same as Figure 4A The installation shown is similar.

[0023] Figure 5A A third installation tool 11 for installing a stop block 12 is shown. The installation tool 11 includes a handle 111, a long rod 112, and a short rod 113. One end of the long rod 112 is connected to the handle 111, and the other end is connected to the short rod 113. A through hole 1221 corresponding to the short rod 113 is provided on the side surface 122 of the stop block 12 near the wide end 121. The short rod 113 can be inserted into the through hole 1221. When installing the stop block 12, the short rod 113 is inserted into the through hole 1221. The installation tool 11 is held and the stop block 12 is installed in the through slot 221 of the anchor plate 2. The short rod 113 is then withdrawn from the side to complete the installation of the stop block 12.

[0024] Figure 5B A fourth type of installation tool 13 for installing a limit block 14 is shown. The installation tool 13 includes a handle 131 and an installation rod 132. The installation rod 132 is in the shape of a long rod, one end of which is connected to the handle 131, and the other end is provided with a magnet 1321. The limit block 14 is made of a magnetic material such as iron or steel, and the end face 1411 of the wide end 141 is flat and can be attracted by the magnet 1321. When installing the limit block 14, the end face 1411 of the wide end 141 of the limit block 14 is attracted to the magnet 1321. The handle 131 is held to insert the limit block 14 into the through slot 221 of the anchor plate 22. The installation tool 13 is then moved to disengage the magnet 1321 from the limit block 14, and the installation of the limit block 14 is completed.

[0025] While all four embodiments of the aforementioned installation tools include handles for easier gripping, the installation tool can also complete the installation of the stopper without a handle. Therefore, the use of the tool may be determined based on actual circumstances. The installation tool may also have other forms, as long as it can complete the installation of the stopper.

[0026] In order to meet the installation requirements of T-head bolts with specifications of M16 to M64, the length of the limit block 5 is usually set to 80 to 200 mm. Figure 6 The stopper 5 is used for an M16 T-head bolt 3. Its flat surface 54 is 80 mm long, its inclined surface 53 has a slope of 1:10, and its surface roughness is 12.5. When the stopper 5 is inserted into the through-slot 221 of the anchor plate 22, a certain gap remains between the stopper 5 and the T-head 32. This ensures smooth installation of the stopper, while preventing the T-head bolt 3 from rotating excessively due to an excessive gap and affecting its usability.

[0027] Considering only the problem to be solved by this application, there is no specific requirement for the size of the limit block 5, and it only needs to be adjusted according to the specifications of the T-shaped head bolt 3. However, considering the actual use effect, for T-shaped head bolts 3 of different specifications, the size of the limit block 5 is best used within a certain range of values, such as Figure 6 As shown, when the specification of the T-head bolt 3 is M16, the length of the flat surface 54 of the stopper 5 is preferably L = 80 mm. When the specification of the T-head bolt 3 is M64, the length of the flat surface 54 of the stopper 5 is preferably L = 200 mm. At the same time, the surface roughness of the stopper 5 is preferably below 12.5, and the slope a of the inclined surface 53 is preferably between 1:10 and 1:20. At this time, after the stopper 5 is inserted into the through slot 221 of the anchor plate 22, a certain gap 15 can be formed between the stopper 5 and the T-head 32 of the T-head bolt 3. This ensures smooth installation of the stopper 5, while preventing the T-head bolt 3 from having an excessively large free rotation angle due to an excessive gap 15, which affects the performance.

[0028] In particular, the T-head bolt sleeve anchor box can also be provided with a pad 1 on the upper part of the sleeve, and the upper surface of the pad 1 is flush with the ground, which can improve the bearing capacity of the ground and make the installation of the ground equipment 6 more stable.

[0029] Finally, it should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back...), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.
