Description

Technical Field

[0001] This utility model relates to the field of building embedded parts technology, specifically to a segmented embedded device and prefabricated building. Background Technology

[0002] With the development of the construction industry, prefabricated buildings are increasingly becoming a part of people's lives. Composite floor slabs, with their advantages of good integrity, flat upper and lower surfaces, and ease of finishing, are widely used in prefabricated buildings. However, in buildings using composite floor slabs, the problem of anchoring the embedded bolts of the I-beams of cantilevered external scaffolding has yet to be adequately solved.

[0003] Currently, there are two main construction methods. One method is to directly embed U-bolts into the upper cast-in-place reinforced concrete layer. This method does not meet the requirement in the "Safety Technical Specification for Steel Pipe Scaffolding with Couplers in Building Construction" that the embedding depth of U-bolts should not be less than 12cm, which poses a quality and safety hazard. The other method is to drill holes in the composite floor slab and then insert embedded bolts into the holes for anchoring. This method requires damaging the structural slab, which creates a risk of leakage. At the same time, the labor cost of drilling and plugging the holes is also greatly increased.

[0004] Therefore, there is an urgent need for an anchoring method that can meet the requirements of the specifications, ensure quality and safety, and is simple, quick, and cost-effective, so as to ensure the normal use of cantilevered frames in composite floor slab buildings. Utility Model Content

[0005] The purpose of this utility model is to provide a segmented pre-embedded device and prefabricated building to meet the requirements of the specifications and achieve anchoring that is safe, simple, quick and cost-effective, thereby solving the above-mentioned problems.

[0006] This utility model is achieved through the following technical solution:

[0007] In the first aspect, this utility model provides a segmented pre-embedded device, including a lower embedded part and an upper component;

[0008] The lower embedded part has an embedded section embedded in the substrate and an extended section extending out of the substrate. Correspondingly, the extended section of the lower embedded part is detachably connected to the upper component.

[0009] The connection between the upper component and the lower embedded part forms the first construction zone, which extends upward from the extended section of the lower embedded part to the connection between the upper component and the lower embedded part, and the second construction zone, which is located above the connection between the upper component and the lower embedded part.

[0010] In one possible design, the depth of the embedded part below the first construction zone is not less than 12 centimeters.

[0011] In one possible design, the embedded part includes a connecting rod and an extension rod. The connecting rod is embedded in the substrate, the lower end of the extension rod is connected to the connecting rod, the upper end of the extension rod extends out of the substrate, and at least two extension rods are provided and spaced apart from the connecting rod.

[0012] In one possible design, there are two outriggers, each connected to both ends of the connecting rod. Correspondingly, the embedded part is constructed as an upward-opening U-shaped screw.

[0013] In one possible design, the upper component is provided with at least two cantilever rods that are respectively connected to the lower embedded parts. Accordingly, the upper component and the cantilever rods are set in a one-to-one correspondence. The second construction area located between two adjacent upper components is a cantilever beam installation area.

[0014] In one possible design, the upper component includes a connecting screw and an adjusting nut;

[0015] The connecting screw is set vertically, and the lower end of the connecting screw is connected to the embedded part through the connecting sleeve. The upper end of the connecting screw is connected to the upper limit plate. The adjusting nut is detachably connected to the connecting screw and is located above the upper limit plate. The adjusting nut is used to limit and fix the connecting screw.

[0016] Accordingly, the upper surface of the first construction zone is not higher than the upper end of the connecting sleeve, and the upper surface of the second construction zone is not higher than the bottom surface of the upper limit plate.

[0017] In one possible design, the upper limit plate is made of angle steel and is used to block the upper end of the cantilever beam installation area.

[0018] In one possible design, the first construction zone is constructed as a reinforced concrete layer, and the cantilever beams are installed in the cantilever beam installation area of ​​the second construction zone, with the cantilever beams fixed to the reinforced concrete layer.

[0019] In one possible design, the embedded section of the lower part is connected to a base plate, the base plate being provided with at least one of the segmented pre-embedded devices, and the base plate being a prefabricated plate.

[0020] Secondly, this utility model provides a prefabricated building, including the aforementioned segmented pre-embedded device.

[0021] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0022] When the embedded part is pre-embedded on the base plate, a reinforced concrete layer is formed on the base plate through the first construction zone, so that the pre-embedding depth of the embedded part meets the technical requirements of the safety specifications, avoids quality and safety risks, and improves construction quality.

[0023] Embedded parts can be prefabricated, and mechanical connections are used to connect them to upper components during on-site construction, simplifying the operation for construction workers and making construction more efficient. This avoids the need to drill holes on-site to insert pre-embedded bolts, which reduces on-site construction, not only reducing the workload of construction workers but also helping to improve construction efficiency. Furthermore, it avoids damaging the floor slab by drilling, thus reducing the risk of leakage. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0033] Example:

[0034] like Figures 1-5 As shown, a segmented pre-embedded device includes a lower embedded part 100 and an upper component 200;

[0035] The lower embedded member 100 has an embedded section embedded in the substrate 300 and an extended section extending out of the substrate 300. Correspondingly, the extended section of the lower embedded member 100 is detachably connected to the upper member 200.

[0036] The connection between the upper component 200 and the lower embedded part 100 forms the boundary, forming a first construction area 400 extending upward from the extended section of the lower embedded part 100 to the connection between the upper component 200 and the lower embedded part 100, and a second construction area 500 located above the connection between the upper component 200 and the lower embedded part 100.

[0037] In the segmented pre-embedded device, the lower embedded part 100 is pre-embedded into the base plate 300, so that the lower embedded part 100 can be manufactured in advance. During on-site construction, the lower embedded part 100 is connected to the upper component 200 through mechanical connection, which simplifies the operation of construction personnel and makes the construction more efficient. After the upper component 200 is connected to the lower embedded part 100, the first construction area 400 and the second construction area 500 are formed, so that the corresponding construction can be completed in the corresponding area.

[0038] It is worth noting that when the embedded part 100 is pre-embedded on the base plate 300, a reinforced concrete layer is formed on the base plate 300 through the first construction zone 400, so that the pre-embedding depth of the embedded part 100 meets the technical requirements of the safety specifications, avoiding quality and safety risks and improving construction quality. Based on this, the problem of the pre-embedding depth of U-shaped embedded bolts being less than 12 cm in the prior art is also solved.

[0039] Furthermore, this avoids the need for on-site drilling to insert pre-embedded bolts, which reduces on-site construction, not only reducing the workload of construction workers but also helping to improve construction efficiency. On the other hand, it avoids damaging the floor slab by drilling, thus reducing the risk of leakage.

[0040] It is easy to understand that, according to actual construction needs, at least one segmented pre-embedded device is provided on the same base plate 300. Through the cooperation of multiple segmented pre-embedded devices, the specific shape of the first construction area 400 and the second construction area 500 is defined to meet the installation of components such as cantilever beams.

[0041] During the work, the pre-embedded positions of the lower embedded parts 100 are selected according to the construction requirements, and then the lower embedded parts 100 are pre-embedded one by one onto the base plate 300. The base plate 300 and the upper component 200 are transported to the construction site. The construction personnel first lay the base plate 300, then connect the lower embedded parts 100 and the upper component 200, and finally carry out the corresponding construction operations in the first construction area 400 and the second construction area 500 respectively.

[0042] Preferably, after construction is completed, the upper component 200 is removed from the lower embedded part 100 to realize the special use and reuse of the upper component 200, and to achieve secondary recycling, which meets the requirements of "saving four things and protecting the environment".

[0043] In one possible implementation, the depth of the embedded part 100 below the first construction zone 400 is not less than 12 cm. Based on the above design scheme, the first construction zone 400 is generally constructed as a reinforced concrete layer. The thickness of the base plate 300 and the thickness of the reinforced concrete layer can ensure that the embedding depth of the embedded part 100 is not less than 12 cm, so that the pre-embedding depth of the embedded part 100 meets the technical requirements of safety specifications and avoids quality and safety risks.

[0044] In one possible implementation, the embedded part 100 includes a connecting rod 101 and an extension rod 102. The connecting rod 101 is embedded in the substrate 300. The lower end of the extension rod 102 is connected to the connecting rod 101. The upper end of the extension rod 102 extends out of the substrate 300. At least two extension rods 102 are provided and spaced apart from the connecting rod 101.

[0045] Based on the above design scheme, the lower parts of the connecting rod 101 and the extension rod 102 are embedded in the substrate 300, and the remaining part of the extension rod 102 extends to the outside of the substrate 300. According to the actual construction requirements, the size of the connecting rod 101 and the extension rod 102, as well as the number of extension rods 102, are selected so that the embedded part 100 can be adapted to different construction requirements, and the applicability and practicality are better.

[0046] Preferably, such as Figure 5 As shown, there are two outriggers 102, each connected to both ends of the connecting rod 101. Correspondingly, the lower embedded part 100 is constructed as an upward-opening U-shaped screw. Based on this, any suitable existing U-shaped screw can be selected for the lower embedded part 100 to reduce economic costs.

[0047] In one possible implementation, the upper component 200 is provided with at least two outriggers 102 that are respectively connected to the lower embedded part 100. Accordingly, the upper component 200 and the outriggers 102 are arranged in a one-to-one correspondence. The second construction area 500 located between two adjacent upper components 200 is a cantilever beam installation area.

[0048] Based on the above design, the lower embedded part 100 is connected to the upper component 200 via the outrigger 102. Correspondingly, the upper component 200 and the outrigger 102 are arranged in a one-to-one correspondence, thereby increasing the height of the segmented pre-embedded device to meet construction requirements. Simultaneously, for upper components 200 connected to the same embedded part, two adjacent upper components 200 can be used to divide a second construction zone 500 to form a cantilever beam installation area. Thus, by using the segmented pre-embedded device in conjunction with the cantilever beam installation, the position of the cantilever beam is defined.

[0049] Optionally, such as Figure 5 As shown, the upper component 200 includes a connecting screw 201 and an adjusting nut 202;

[0050] The connecting screw 201 is vertically arranged. The lower end of the connecting screw 201 is connected to the lower embedded part 100 through the connecting sleeve 600, and the upper end of the connecting screw 201 is connected to the upper limit plate 700. The adjusting nut 202 is detachably connected to the connecting screw 201 and is located above the upper limit plate 700. The adjusting nut 202 is used to limit and fix the connecting screw 201.

[0051] Accordingly, the upper surface of the first construction zone 400 is not higher than the upper end of the connecting sleeve 600, and the upper surface of the second construction zone 500 is not higher than the bottom surface of the upper limit plate 700.

[0052] Based on the above design, the connecting screw 201 is used to connect the lower embedded part 100 and the upper limit plate 700. The base plate 300 and the upper limit plate 700 cooperate with each other to limit the total height of the two construction areas. At the same time, the adjusting nut 202 cooperates with the upper limit plate 700 to limit and fix the connecting rod 101.

[0053] During construction, the first construction zone 400 is generally constructed as a reinforced concrete layer. Considering that the upper component 200 can be reused, the upper surface of the first construction zone 400 is limited to not exceeding the upper end of the connecting sleeve 600 to prevent the reinforced concrete from connecting with the connecting bolt 201. Correspondingly, the area above the first construction zone 400 up to the bottom surface of the upper limit plate 700 is the second construction zone 500. The second construction zone 500 is generally used for installing cantilever beams, ensuring that the height of the second construction zone 500 is adapted to the cantilever beams.

[0054] In one possible implementation, the upper limit plate 700 is made of angle steel and is used to seal the upper end of the cantilever beam installation area. Based on the above design, angle steel has advantages such as high strength, corrosion resistance, multifunctionality, easy processing, and low maintenance costs, making it suitable for different construction environments.

[0055] In one possible implementation, the first construction zone 400 is constructed as a reinforced concrete layer, and cantilever beams are installed in the cantilever beam installation area of ​​the second construction zone 500, with the cantilever beams fixed to the reinforced concrete layer. Based on the above design scheme, the parameters of the reinforced concrete layer are adjusted according to the actual construction, which will not be elaborated here. I-beams are preferred for the cantilever beams, as they have advantages such as structural stability, good load-bearing capacity, convenient processing, easy transportation and construction, and durability, making them suitable for different construction environments.

[0056] In one possible implementation, the embedded section of the lower embedded part 100 is connected to a base plate 300, and the base plate 300 is provided with at least one of the segmented pre-embedded devices, and the base plate 300 is selected as a precast slab. Based on the above design scheme, the number of lower embedded parts 100 can be determined according to actual construction needs, and correspondingly, the number of upper components 200 is also determined, making the use more flexible and convenient. Precast slabs have advantages such as low cost, convenient installation, and material saving. It is easy to understand that the base plate 300 can also be selected from any other suitable material.

[0057] This embodiment introduces a prefabricated building based on the segmented pre-embedded device. The prefabricated building includes the segmented pre-embedded device. Based on the above design, the prefabricated building can also include other suitable functional modules, resulting in richer functionality to meet different work requirements and improved practicality. Furthermore, it is easily understood that these functional modules can be any suitable existing equipment, offering a wide range of choices.

[0058] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
