Description

Technical Field

[0001] The present application relates to the technical field of construction tools, and in particular to an assembly mould for embedded bolts in steel structure engineering. Background Art

[0002] Embedded bolts play an important role in construction projects and industrial facilities. They need to be accurately pre-installed before pouring structural concrete to ensure reliable connection of subsequent components. Since the positioning accuracy of embedded bolts directly affects the stability of the structure and the overall quality of the project, their assembly requirements are extremely strict.

[0003] Traditional embedded bolt assembly methods often rely on manual operations, including manual splicing and welding. Such a process is not only labor-intensive, but also difficult to maintain consistency due to human factors, thus reducing installation accuracy. Thermal deformation and stress release generated during welding may also cause the embedded position to shift, further increasing the error.

[0004] As a commonly used tool, wooden formwork is used for plane positioning of embedded bolts, which provides great convenience for the assembly of embedded bolts. However, the physical characteristics of wooden formwork determine that its rigidity and stability are insufficient, and it is easily affected by environmental humidity and mechanical stress during use, which leads to deformation. This deformation may cause the position of embedded bolts to exceed the tolerance and cause dislocation, which seriously affects the quality of the project. Summary of the invention

[0005] To this end, the present application provides a pre-embedded bolt assembly mold for steel structure engineering to solve the problem in the prior art that wooden formwork is easy to deform, resulting in low precision and low efficiency in assembling pre-embedded bolts.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0007] A steel structure engineering embedded bolt assembly mold, comprising a bottom plate, a middle plate and an upper plate made of steel templates, wherein the bottom plate, the middle plate and the upper plate are fixedly connected by a plurality of connecting columns;

[0008] The middle plate and the bottom plate are provided with a plurality of bolt holes for inserting embedded bolts, and the bolt holes on the middle plate correspond coaxially to the bolt holes on the bottom plate one by one; the bolt holes on the middle plate are through holes, and the bolt holes on the bottom plate are blind holes;

[0009] The upper plate is a frame-type structure, and a plurality of half holes are provided on the inner side of the upper plate, the half holes are adapted to the embedded bolts and are coaxially arranged with the bolt holes;

[0010] A distance is reserved between the upper flat plate and the middle flat plate for the embedded bolt assembly to be assembled and fixed.

[0011] Optionally, a base is further included, and the base is located below the bottom plate, and a rotating disk is connected between the base and the bottom plate, so that the bottom plate can rotate relative to the base.

[0012] Optionally, the connecting column is a through-thread screw, and circular holes are provided on the bottom plate, the middle plate and the upper plate. The connecting column can pass through the circular holes, and the connecting column is threaded with multiple locking nuts for installing the bottom plate, the middle plate and the upper plate on the connecting column.

[0013] Optionally, the edges of the bottom plate, the middle plate and the upper plate are all bent downward to form a box-shaped structure with the opening facing downward.

[0014] Optionally, a plurality of magnets are provided on the upper flat plate, and the magnets are arranged at positions corresponding to the half holes, so as to adsorb and position the embedded bolts.

[0015] Optionally, the upper flat plate includes three fixed parts and one rotating part, the three fixed parts are connected to form a semi-enclosed structure with an opening on one side, one end of the rotating part is rotatably connected to a connecting column on one side of the opening, and the rotating part rotates to open and close the opening.

[0016] Optionally, a positioning hole for the connecting column to pass through is formed at one end of the rotating part away from the rotating shaft.

[0017] Optionally, a clamping plate is hinged on the inner side of the upper flat plate, and two clamping plates are provided and respectively arranged on two opposite fixing parts; a half hole is opened on the inner side of the clamping plate, and the half hole is coaxial with the bolt hole.

[0018] Optionally, reinforcing ribs are connected between the middle flat plate and the upper flat plate.

[0019] Compared with the prior art, this application has at least the following beneficial effects:

[0020] 1. The mold is made of steel template, which is not easy to deform and has a long service life, which can ensure the accuracy of the assembly of the embedded bolt assembly. In addition, steel materials are conductive, and the ground wire can be directly connected to the bottom of the mold. When welding the embedded bolt assembly, there is no need to move the ground wire back and forth, which greatly improves the assembly efficiency.

[0021] 2. The setting of the rotating disk and the base allows the entire mold to rotate freely, so that when welding the embedded bolt assembly, workers do not have to operate around the mold, making assembly more convenient and labor-saving.

[0022] 3. The setting of the magnet enables the embedded bolt to automatically enter the correct position under the attraction of the magnet after the embedded bolt is inserted into the mold. Under the action of the magnetic attraction, the embedded bolt has higher stability and reliability in the half hole, preventing the embedded bolt from shaking during welding.

[0033] Embodiment 1

[0034] A steel structure engineering embedded bolt assembly mold, reference Figure 1-Figure 4 , including a bottom plate 1, a middle plate 2 and an upper plate 3 made of steel formwork, and the bottom plate 1, the middle plate 2 and the upper plate 3 are fixedly connected by multiple connecting columns 4.

[0035] Furthermore, a base 5 is provided below the bottom plate 1, a bearing is welded on the base 5, a rotating disk 6 is connected to the outer side of the bearing, and the bottom plate 1 is mounted on the rotating disk 6 so that the main structure above can rotate freely relative to the base 5. In the embodiment of the present application, the base 5 is a triangular support made of steel material, and a welding ground wire is connected to the triangular support. During the welding process, the worker only needs to rotate the main structure above without moving the ground wire.

[0036] In the main structure above, multiple bolt holes 7 for inserting embedded bolts are provided on both the middle slab 2 and the bottom slab 1. The bolt holes 7 on the middle slab 2 correspond coaxially to the bolt holes 7 on the bottom slab 1. The bolt holes 7 on the middle slab 2 are through holes, and the bolt holes 7 on the bottom slab 1 are blind holes, so that after the embedded bolts are inserted, the bottom will not directly contact the ground, but will be inserted on the bottom slab 1. The position of the embedded bolts is limited by the blind holes and the through holes to ensure the stability of the embedded bolts.

[0037] In order to improve the stability of the embedded bolts, holes that match the embedded bolts are also provided on the upper plate 3. Specifically, the upper plate 3 is a frame-type structure, and the holes are half holes 8, which are opened at the inner side of the upper plate 3 and are coaxially arranged with the bolt holes 7. After the embedded bolts are inserted into place, the lower half is in the two bolt holes 7, and the upper half cooperates with the half holes 8 to maintain overall stability.

[0038] During welding, the middle plate 2 and the bottom plate 1 are mainly responsible for fixing the embedded bolts, and the distance between them is consistent with the length of the thread of the lower half of the embedded bolts. The upper plate 3 and the middle plate 2 are the locations for assembling the embedded bolt assembly, and the distance between them is slightly shorter than the length of the bolt without thread in the embedded bolt design drawing, so as to avoid misprocessing the thread of the embedded bolt. You only need to insert the embedded bolts into place, and then connect and fix the embedded bolts with connecting steel bars between the middle plate 2 and the upper plate 3 to complete the assembly and fixation of the embedded bolt assembly.

[0039] It should be noted that the upper plate 3 includes three fixed parts 31 and one rotating part 32. The three fixed parts 31 are connected to form a semi-enclosed structure with an opening on one side, and the rotating part 32 is rotatably connected to the opening for opening and closing the opening. Specifically, the connecting column 4 is provided on the fixed part 31, wherein two connecting columns 4 are respectively located on the two fixed parts 31 at the opening, one end of the rotating part 32 is sleeved on one of the connecting columns 4 and can rotate freely, and the other end is provided with a positioning hole 33 for the other connecting column 4 to pass through.

[0040] Before welding, pull out the free end of the rotating part 32 upward to separate the positioning hole 33 from the connecting column 4, and then rotate the rotating part 32 outward to open the opening, which makes it easier to insert the embedded bolts. After installation, rotate the rotating part 32 inward and slightly raise the free end of the rotating part 32 upward so that the positioning hole 33 can be higher than the connecting column 4. After alignment, lower it so that the positioning hole 33 matches the connecting column 4.

[0041] When the number of embedded bolts is large (greater than 6), in addition to opening a corresponding number of bolt holes on the bottom plate 1, the middle plate 2 and the upper plate 3, the removal of the embedded bolt assembly after welding is also considered.

[0042] Therefore, in order to prevent the embedded bolt assembly from being blocked, a clamping plate 9 is hinged on the upper flat plate 3. Two clamping plates 9 are provided, which are respectively installed on the inner sides of the two opposite fixing parts 31. A half hole 8 is opened on the inner side of the clamping plate 9 at the position corresponding to the bolt hole 7, and the half hole 8 is ensured to be coaxial with the bolt hole 7. By flipping the clamping plate 7 upward to be perpendicular to the surface of the upper flat plate 3, the embedded bolt can be smoothly passed through, and by flipping the clamping plate 7 downward to be flush with the surface of the upper flat plate 3, the embedded bolt can be limited and fixed.

[0043] Furthermore, in order to improve the stability of the embedded bolts, a plurality of magnets 10 are provided on the upper surfaces of the fixed portion 31 and the rotating portion 32. These magnets 10 are respectively arranged at positions corresponding to the half holes 8 for adsorbing and positioning the embedded bolts, thereby improving the stability of the embedded bolts through magnetic attraction.

[0044] In the embodiment of the present application, the connecting column 4 is a through-thread screw, and correspondingly, a circular hole is opened on the bottom plate 1, the middle plate 2 and the upper plate 3, and the diameter of the circular hole is slightly larger than the diameter of the connecting column 4, so that the connecting column 4 can pass through the circular hole. A plurality of locking nuts are threadedly matched on the connecting column 4, which are used to install the bottom plate 1, the middle plate 2 and the upper plate 3 on the connecting column 4.

[0045] In order to improve the strength of the bottom plate 1, the middle plate 2 and the upper plate 3, the edges of the bottom plate 1, the middle plate 2 and the upper plate 3 are bent downward by 90 degrees to form a box-like structure with an opening facing downward, which has higher strength and deformation resistance than a plane structure.

[0046] Furthermore, in order to improve the reliability of the mold, a reinforcing rib 11 is connected between the middle plate 2 and the upper plate 3. The reinforcing rib 11 also adopts a through-thread screw, which is matched with a nut to connect and fix the reinforcing rib 11 with the middle plate 2 and the upper plate 3.

[0047] This application is not a universal mold and needs to be assembled specifically according to the model of the embedded bolt design drawing to be processed. Therefore, the processing accuracy is very high and the processing efficiency can be greatly improved.

[0048] Embodiment 2

[0049] A steel structure engineering embedded bolt assembly mold, which is different from the first embodiment in that it is suitable for the case where the number of embedded bolts is less than 6. When the number of embedded bolts is small, the assembled embedded bolt assembly is also easier to remove, so no clamping plate 9 is provided on the upper flat plate 3, and only corresponding half holes 8 are provided on the inner sides of the rotating part 32 and the fixed part 31.

[0050] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
