Description

Technical Field

[0001] This application relates to the field of construction tool technology, specifically to a mold for assembling pre-embedded bolts in steel structure engineering. Background Technology

[0002] Embedded bolts play a crucial role in building construction and industrial facilities. They need to be accurately pre-installed before the structural concrete is poured to ensure reliable connections for subsequent components. Because the positioning accuracy of embedded bolts directly affects the structural stability and overall project quality, their assembly requirements are extremely stringent.

[0003] Traditional methods of assembling embedded bolts often rely on manual operation, including manual splicing and welding. This 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 during welding can also cause misalignment of the embedded bolt position, further increasing errors.

[0004] Wooden formwork, a commonly used tool, is used for the planar positioning of embedded bolts, greatly facilitating their assembly. However, the physical properties of wooden formwork result in insufficient rigidity and stability, making it susceptible to deformation due to environmental humidity and mechanical stress during use. This deformation can lead to misalignment of the embedded bolts, severely impacting project quality. Utility Model Content

[0005] Therefore, this application provides a pre-embedded bolt assembly mold for steel structure engineering to solve the problem that wooden templates are prone to deformation, resulting in low assembly accuracy and low efficiency of pre-embedded bolts in the existing technology.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A steel structure engineering pre-embedded bolt assembly mold includes 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 multiple connecting columns;

[0008] The middle plate and the bottom plate are provided with multiple bolt holes for pre-embedded bolts to be inserted. The bolt holes on the middle plate and the bolt holes on the bottom plate are coaxially corresponding 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 structure. Multiple half holes are opened on the inner side of the upper plate. The half holes are adapted to the pre-embedded bolts and are coaxially arranged with the bolt holes.

[0010] A distance is provided between the upper plate and the middle plate for the assembly and fixing of the pre-embedded bolt assembly.

[0011] Optionally, it also includes a base, which is located below the bottom plate and connected to a rotating disk so that the bottom plate can rotate relative to the base.

[0012] Optionally, the connecting post is a threaded rod, and the bottom plate, middle plate and top plate are all provided with round holes, through which the connecting post can pass. The connecting post is threaded with multiple locking nuts for mounting the bottom plate, middle plate and top plate on the connecting post.

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

[0014] Optionally, the upper plate is provided with multiple magnets, which are positioned corresponding to the half-holes to attract and position the pre-embedded bolts.

[0015] Optionally, the upper 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 post on one side of the opening. The rotating part rotates to open and close the opening.

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

[0017] Optionally, a clamping plate is hinged to the inner side of the upper plate, and two clamping plates are provided, which are respectively set 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, a reinforcing rib connects the middle plate and the upper 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 easily deformed, has a long service life, and can ensure the accuracy of the assembly of the pre-embedded bolt components. Moreover, the steel material is conductive, and the ground wire can be directly connected to the bottom of the mold. When welding the pre-embedded bolt components, there is no need to move the ground wire back and forth, which greatly improves the assembly efficiency.

[0021] 2. The rotating plate and base allow the entire mold to rotate freely, so workers do not have to walk around the mold when welding the pre-embedded bolt components, making assembly more convenient and labor-saving.

[0022] 3. The magnet design allows the pre-embedded bolt to automatically enter the correct position after it is inserted into the mold. Furthermore, the magnetic attraction enhances the stability and reliability of the pre-embedded bolt within the semi-hole, preventing it from shaking during welding. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0032] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0033] Example 1

[0034] A steel structure engineering pre-embedded bolt assembly mold, referring to Figures 1-4 It includes a bottom plate 1, a middle plate 2 and an upper plate 3 made of steel templates, which are fixedly connected by multiple connecting columns 4.

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

[0036] In the upper main structure, both the middle plate 2 and the bottom plate 1 have multiple bolt holes 7 for inserting pre-embedded bolts. The bolt holes 7 on the middle plate 2 and the bolt holes 7 on the bottom plate 1 are coaxially aligned. The bolt holes 7 on the middle plate 2 are through holes, while the bolt holes 7 on the bottom plate 1 are blind holes, ensuring that the bottom of the pre-embedded bolt does not directly contact the ground after insertion, but rather rests on the bottom plate 1. The blind holes and through holes together define the position of the pre-embedded bolts, ensuring their stability.

[0037] To improve the stability of the embedded bolts, the upper plate 3 is also equipped with holes that match the embedded bolts. Specifically, the upper plate 3 has a frame structure, and the holes are half-holes 8, located on 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 located within the two bolt holes 7, and the upper half mates with the half-holes 8, maintaining overall stability.

[0038] During welding, the middle plate 2 and the bottom plate 1 are primarily responsible for fixing the embedded bolts, and the distance between them is consistent with the length of the threaded portion of the lower half of the embedded bolt. The area between the upper plate 3 and the middle plate 2 is where the embedded bolt assembly is located; the distance between them is slightly shorter than the length of the bolt without threads in the embedded bolt design drawings. This avoids misprocessing the threaded portion of the embedded bolt. Simply insert the embedded bolts into place, and then connect and fix them between the middle plate 2 and the upper plate 3 using connecting steel bars to complete the assembly and fixing 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. The rotating part 32 is rotatably connected to the opening and used to open and close the opening. Specifically, the connecting posts 4 are inserted through the fixed parts 31, with two connecting posts 4 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 posts 4 and can rotate freely, while the other end has a positioning hole 33 for the other connecting post 4 to pass through.

[0040] Before welding, pull the free end of the rotating part 32 upward to disengage 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 pre-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 is higher than the connecting column 4. After alignment, lower it so that the positioning hole 33 fits with the connecting column 4.

[0041] When there are a large number of pre-embedded bolts (more than 6), in addition to opening the corresponding number of bolt holes on the bottom plate 1, the middle plate 2 and the top plate 3, the removal of the pre-embedded bolt assembly after welding is also taken into consideration.

[0042] Therefore, to prevent obstruction of the pre-embedded bolt assembly, a retaining plate 9 is hinged to the upper plate 3. Two retaining plates 9 are provided, respectively installed on the inner sides of two opposite fixing parts 31. Half holes 8 are formed on the inner side of the retaining plate 9 at the corresponding positions of the bolt holes 7, ensuring that the half holes 8 and bolt holes 7 are coaxial. By flipping the retaining plate 7 upwards to be perpendicular to the surface of the upper plate 3, the pre-embedded bolt can pass through smoothly; by flipping the retaining plate 7 downwards to be flush with the surface of the upper plate 3, the pre-embedded bolt can be limited and fixed.

[0043] Furthermore, in order to improve the stability of the embedded bolts, multiple magnets 10 are provided on the upper surfaces of both the fixing part 31 and the rotating part 32. These magnets 10 are respectively positioned corresponding to the half-hole 8 and are used to attract and position the embedded bolts, thereby improving the stability of the embedded bolts through magnetic attraction.

[0044] In this embodiment, the connecting post 4 is a threaded rod. Correspondingly, the bottom plate 1, the middle plate 2, and the top plate 3 are all provided with round holes. The diameter of the round holes is slightly larger than the diameter of the connecting post 4, so that the connecting post 4 can pass through the round holes. Multiple locking nuts are threaded onto the connecting post 4 for mounting the bottom plate 1, the middle plate 2, and the top plate 3 onto the connecting post 4.

[0045] To improve the strength of the bottom plate 1, the middle plate 2, and the top plate 3, the edges of the bottom plate 1, the middle plate 2, and the top plate 3 are all bent downwards at 90 degrees to form a box-shaped structure with the opening facing downwards. Compared with a planar structure, it has higher strength and resistance to deformation.

[0046] Furthermore, 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 uses a threaded rod with a nut fitted on it to connect and fix the reinforcing rib 11 to the middle plate 2 and the upper plate 3.

[0047] This application is not a general-purpose mold. It needs to be assembled specifically according to the model of the pre-embedded bolts in the design drawings. Therefore, the processing accuracy is very high, and the processing efficiency can be improved to the maximum extent.

[0048] Example 2

[0049] A pre-embedded bolt assembly mold for steel structure engineering differs from Embodiment 1 in that it is suitable for situations where the number of pre-embedded bolts is less than 6. When the number of pre-embedded bolts is small, the assembled pre-embedded bolt assembly is easier to remove. Therefore, a retaining plate 9 is not provided on the upper plate 3; only corresponding half-holes 8 are opened on the inner sides of the rotating part 32 and the fixing part 31.

[0050] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
