Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel component embedded base, specifically a steel component embedded base. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. During the construction of steel structure buildings, to make the installation structure of steel components more stable, embedded bases are made for the steel components in the building project. By embedding the steel component bases underground, the stability of the steel structure is increased.
[0003] Existing steel component embedded bases involve first digging an embedded pit at a designated location, then laying reinforcing bars and embedded parts, and pouring formwork. During this process, measuring equipment (e.g., a total station) is used to ensure the accurate position of the embedded parts. Finally, concrete is poured to form the main body of the base. The overall construction cycle is long, and the concrete is easily affected by external factors during the curing process, which can cause the position of the embedded parts to shift, making it difficult to control the construction quality. Therefore, this paper proposes a steel component embedded base. Utility Model Content
[0004] The purpose of this utility model is to provide a pre-embedded base for steel components in order to solve the problems mentioned above.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel component pre-embedded base, including a pre-embedded bolt, a precast base integrally formed on the outer side of the pre-embedded bolt, a groove integrally formed on the outer wall side of the precast base, and the pre-embedded bolt passing through the upper and lower ends of the groove; the position of the pre-embedded bolt is fixed by the precast base, and the weight increase of the precast base makes it easy to place the whole in the pre-embedded pit without shifting, and the groove is used to allow the poured concrete to contact the pre-embedded bolt and increase the connection force between the concrete and the precast base.
[0006] As a further improvement of this utility model, the interior of the precast base is also provided with reinforcing steel bars, and the two ends of some of the reinforcing steel bars extend to the two outer ends of the precast base.
[0007] As a further embodiment of this utility model: a base plate is welded and fixed to the bottom of the plurality of pre-embedded bolts, a top plate is sleeved on the top of the outer side of the pre-embedded bolts, and two sets of nuts are symmetrically threaded on the outer side of the pre-embedded bolts with the top plate as the center. The base plate and the top plate are located at the upper and lower ends of the precast base, respectively, to realize the height limitation when the precast base is formed.
[0008] As a further embodiment of this utility model: the outer wall dimensions of the bottom plate and the top plate are larger than the outer wall dimensions of the prefabricated base, and the bottom plate and the top plate are provided with multiple perforations arranged in a matrix.
[0009] As a further improvement of this utility model: the number and distribution of the pre-embedded bolts correspond one-to-one with the number and position of the mounting holes on the bottom of the steel structure; both sides of the precast base are formed with grooves and multiple grooves are formed in the vertical direction of the precast base.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] By prefabricating a heavy precast base in the factory, it can be placed in the pre-embedded pit without shifting, thus ensuring the accurate positioning of the pre-embedded bolts. Compared with the traditional method of laying pre-embedded bolts on site, this method is not only faster and more controllable in terms of construction quality, but also more precise.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-3 In this embodiment of the utility model, a steel component pre-embedded base includes pre-embedded bolts 1. The number and distribution of the pre-embedded bolts 1 correspond one-to-one with the number and position of the mounting holes on the bottom of the steel structure. A prefabricated base 2 is integrally formed on the outer side of the pre-embedded bolts 1. A groove 3 is integrally formed on the outer side of the prefabricated base 2. Grooves 3 are formed on both sides of the prefabricated base 2, and multiple grooves 3 are formed in the vertical direction of the prefabricated base 2. Multiple pre-embedded bolts 1 pass through the upper and lower ends of the grooves 3.
[0018] The position of the pre-embedded bolt 1 is fixed by the pre-formed base 2. The weight of the pre-formed base 2 makes it easy to place the whole in the pre-embedded pit and prevent it from shifting. The groove 3 is used to allow the poured concrete to contact the pre-embedded bolt 1 and increase the connection force between the concrete and the pre-formed base 2.
[0019] A base plate 5 is welded and fixed to the bottom of multiple pre-embedded bolts 1. A top plate 6 is sleeved on the top of the outer side of the pre-embedded bolts 1. Two sets of nuts 8 are symmetrically threaded on the outer side of the pre-embedded bolts 1 with the top plate 6 as the center. The base plate 5 and the top plate 6 are located at the upper and lower ends of the precast base 2, respectively, to achieve the height limitation when the precast base 2 is formed.
[0020] In this embodiment, it should be noted that the prefabricated base 2 is manufactured in the factory and then transported to the construction site. During factory production, the pre-embedded bolts 1 are welded and fixed to the base plate 5 according to the number of mounting holes and the material arrangement on the steel structure base plate. Then, a set of nuts 8 are threaded to the pre-embedded bolts 1, and the top plate 6 is sleeved with multiple pre-embedded bolts 1 (it should be noted that the top plate 6 has through holes for the pre-embedded bolts 1 to pass through). Then, another set of nuts 8 are threaded to the pre-embedded bolts 1. The height of the top plate 6 can be adjusted and fixed by adjusting the height of the two sets of nuts 8.
[0021] Then, the corresponding casting template is laid between the bottom plate 5 and the top plate 6. Finally, concrete can be poured into the casting template to form the precast base 2 and the groove 3 in one piece.
[0022] During construction, the precast base 2 is placed in the pre-embedded pit as a whole. After the position of the pre-embedded bolt 1 is adjusted and determined, concrete can be poured into the pre-embedded pit. At this time, the concrete will cover the bottom plate 5, the top plate 6, and the precast base 2 in all directions, and the concrete will fill the area of the groove 2, so as to achieve contact coverage of the pre-embedded bolt 1. After the concrete in the pre-embedded pit solidifies, the installation of the pre-embedded bolt 1 is completed.
[0023] By prefabricating a heavy precast base 2 in the factory, it can be placed in the pre-embedded pit without shifting, thus ensuring the accurate position of the pre-embedded bolt 1. Compared with the traditional method of laying the pre-embedded bolt 1 on site, the construction efficiency is faster, the construction quality is controllable, and the construction accuracy is higher.
[0024] Please refer to this carefully. Figures 1-3 The interior of the precast base 2 is also equipped with reinforcing steel bars 4, and the two ends of some of the reinforcing steel bars 4 extend to the two ends of the exterior of the precast base 2.
[0025] The outer wall dimensions of the base plate 5 and the top plate 6 are larger than the outer wall dimensions of the precast base 2, and multiple perforations 7 are provided on the base plate 5 and the top plate 6 in a matrix distribution.
[0026] In this embodiment: the reinforcing steel bars 4 laid inside the precast base 2 give the precast base 2 high strength, and when concrete is poured inside the pre-embedded pit, the concrete covers the reinforcing steel bars 4 protruding from the precast base 2, which further enhances the overall connection between the concrete and the precast base 2 after solidification, thus meeting the requirements for laying steel structures.
[0027] In addition, when pouring concrete inside the pre-embedded pit, the concrete can fill the holes 7 on the bottom plate 5 and top plate 6 on site, which further increases the contact area between the bottom plate 5, top plate 6 and the concrete, making the overall strength stronger after solidification (it should be noted that when the precast base 2 is formed, a bottom plate is also laid at the bottom of the bottom plate 5, that is, the bottom of the precast base 2 fills some of the holes 7 on the bottom plate 5).
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
