Description

Technical Field

[0001] This utility model relates to the field of modular integrated building technology, and in particular to a suspension point device for modular integrated buildings and a modular integrated building. Background Technology

[0002] Chinese patent document CN221837753U discloses a pre-embedded herringbone tail plate lifting point for concrete components. This device enhances the friction with the concrete through the herringbone tail plate and U-shaped anchor bars, preventing it from being pulled out alone or damaging the surrounding concrete during hoisting. The pull-out resistance of the herringbone tail plate lifting point is enhanced by the notch set on the side in conjunction with the zigzag anti-pull-out bars, which can effectively resist uneven tension during lateral hoisting. It is simple to embed and does not require welding.

[0003] However, the pre-embedded herringbone tail plate lifting point in this concrete component has the following shortcomings: First, its function is singular, serving only as a lifting hook, which cannot meet the multi-functional requirements of modular integrated buildings for embedded parts; second, when applied to modular integrated building boxes, due to the limited reserved space at the top of the box, it is easy to conflict with the positions of other embedded parts such as positioning cones, thus limiting its scope of use; finally, this device will hinder the installation of upper modules, requiring on-site cutting, increasing the hot work process, and increasing the risk of exposed hook corrosion. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a new type of lifting point device for modular integrated buildings and a modular integrated building, aiming to solve the technical problem that the existing concrete components with pre-embedded herringbone tail plate lifting points have a single function and can only be used as lifting hooks.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] In a first aspect, this utility model provides a lifting point device for modular integrated buildings, the modular integrated buildings including multiple box modules, characterized in that: the lifting point device includes a positioning cone and a pre-embedded anchor;

[0009] The top of the box module of the modular integrated building is embedded with pre-embedded anchors. The upper end of the pre-embedded anchors is fixedly connected to the bottom of the positioning cone. The positioning cone is used to position two adjacent box modules. The positioning cone is provided with lifting holes, which are used as lifting points for the box modules.

[0010] Optionally, the positioning cone includes a cone body and a base plate;

[0011] The lower surface of the base plate is connected to the upper end of the pre-embedded anchor, and a cone is fixedly installed on the upper surface of the base plate, with lifting holes opened on the cone.

[0012] Alternatively, the cone and base plate are integrally cast galvanized iron parts.

[0013] Optionally, the sides of the cone are smooth and inclined in the lower left and lower right directions, respectively.

[0014] Optionally, the pre-embedded anchor is an anchor tail iron, which is U-shaped and connected to the lower surface of the base plate at both ends.

[0019] (III) Beneficial Effects

[0020] The beneficial effects of this utility model are as follows: The lifting point device for modular integrated buildings includes a positioning cone and pre-embedded anchors. Pre-embedded anchors are embedded in the top of the box modules of the modular integrated building. The upper end of the pre-embedded anchors is fixedly connected to the bottom of the positioning cone. The positioning cone is used to position two adjacent box modules, and a lifting hole is provided on the positioning cone, which serves as the lifting point for the box module. Compared to existing pre-embedded herringbone tail plate lifting points in concrete components, the lifting point device of this utility model combines the functions of the positioning cone and the lifting point, pre-embedded inside the integrated building box.

[0026] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are used interchangeably with other directional terms. Figure 2 The orientation is used as a reference.

[0027] Example 1:

[0028] like Figure 1 As shown, this embodiment provides a lifting point device for modular integrated buildings. The modular integrated building includes multiple box modules, and the lifting point device includes a positioning cone and pre-embedded anchors.

[0029] The top of the box module of the modular integrated building is embedded with pre-embedded anchors. The upper end of the pre-embedded anchors is fixedly connected to the bottom of the positioning cone. The positioning cone is used to position two adjacent box modules. The positioning cone is provided with lifting holes 3, which are used as lifting points for the box modules. This makes the lifting and positioning of the box modules more convenient and stable.

[0030] Preferably, the positioning cone includes a cone 2 and a base plate 4. The base plate 4 is embedded in the upper surface of the housing module, and the lower surface of the base plate 4 is fixedly connected to the upper end of the pre-embedded anchor. The cone 2 is fixedly mounted on the upper surface of the base plate 4, and the lifting hole 3 is opened on the cone 2. It should be noted that the base plate 4 is embedded in the upper surface of the housing module so that the upper surface of the base plate 4 is flush with the upper surface of the housing module.

[0031] The cone 2 and the base plate 4 are preferably integrally cast galvanized iron parts. It should be noted that galvanizing the outer surface of the iron parts can prevent the cone 2 and the base plate 4 from rusting.

[0032] In addition, the cone 2 is divided into two parts, the lower part being a cuboid with arc-shaped protrusions on both sides, the outer surface of which is a smooth arc surface; the upper part is a frustum, with smooth arc surfaces on both sides as well.

[0033] Preferably, the base plate 4 has a length of 140-160mm and a width of 90-110mm. The cone 2 has an overall length of 80mm, a width of 55mm, and a height of 75mm. The lifting hole 3 has a diameter of 40-45mm.

[0034] Furthermore, the cone 2 is cone-shaped, narrower at the top and wider at the bottom. The left and right sides of the cone 2 are smooth and inclined in the lower left and lower right directions, respectively, so as to facilitate the insertion of the cone 2 into the reserved groove of the upper box module.

[0035] Preferably, the pre-embedded anchor is an anchor tail iron 5, which is U-shaped and has both ends connected to the lower surface of the base plate 4.

[0036] Preferably, the number of anchor tail irons 5 is at least two to ensure the stability of the connection between the lifting point device and the box module.

[0037] The anchor tailings 5 ​​are preferably threaded steel bars to provide sufficient strength and durability. The diameter of the threaded steel bars is 16-20mm, and the projected length of the threaded steel bars in the vertical plane after being bent into a U-shape is 1100-1400mm.

[0038] The lifting point device in this embodiment combines the functions of a positioning cone and a lifting point, and is pre-embedded inside the box module of the integrated building. By opening a lifting hole 3 on the cone 2 reserved at the top of the lower box module, the positioning cone can also serve as a lifting point, meeting the multifunctional requirements of modular integrated buildings for embedded parts. In addition, the modular integrated building in this embodiment solves the conflicts and installation problems existing in the prior art by optimizing the design of the lifting point device, and has significant technical advantages and practical application value.

[0039] Example 2:

[0040] Reference Figure 2 This embodiment provides a modular integrated building, including a lower box module 1, an upper box module 6, and the lifting point device of embodiment 1;

[0041] The lower housing module 1 is equipped with a lifting point device on its top, and the upper housing module 6 has a groove 7 at its bottom corresponding to the installation area of ​​the lifting point device, so that the positioning cone of the lifting point device can be inserted.

[0042] The modular integrated building in this embodiment allows the positioning cone, which also serves as a lifting point, to be hidden in the reserved groove of the upper box module 6, thereby avoiding on-site cutting of the lifting point device and additional anti-rust operations on the lifting point device, which improves construction efficiency and safety.

[0043] In this embodiment, the groove 7 at the bottom of the upper box module 6 is a rectangular groove. The length, width and height of the rectangular groove are slightly larger than the size of the cone 2 of the positioning cone, so as to facilitate the insertion of the cone 2.

[0044] Preferably, the number of lifting points on the top of the lower housing module 1 is the same as the number of grooves 7 on the bottom of the upper housing module 6, and is at least three.

[0045] It should be noted that the lower box module 1 and the upper box module 6 are two adjacent box modules. In fact, both the lower box module 1 and the upper box module 6 are equipped with lifting points at their tops and recesses 7 at their bottoms. During the assembly of the modular integrated building, the lower box module 1 is first hoisted to a preset position using the lifting points at its top. Then, the upper box module 6 is hoisted to directly above the lower box module 1 using the lifting points at its top, ensuring that the recesses 7 at the bottom of the upper box module 6 correspond one-to-one with the cones 2 at the top of the lower box module 1. Finally, the upper box module 6 is lowered, ensuring that the cones 2 are inserted into the corresponding recesses 7, achieving precise positioning between the upper box module 6 and the lower box module 1. After completing other connections between these two box modules, the assembly of the next box module can proceed.

[0046] The remaining parts that are the same as in Example 1 will not be repeated here.

[0047] Example 3:

[0048] This embodiment provides another modular integrated building. Unlike embodiment 2, the groove walls on both sides of the groove 7 at the bottom of the upper box module 6 in this embodiment are smooth and inclined to facilitate the entry of the cone 2 into the groove 7.
