Description

Technical Field

[0001] This utility model relates to the field of modular building technology, and in particular to an installation and positioning device for a modular building box. Background Technology

[0002] Modular building is an emerging building structure system where each room is a prefabricated module manufactured in a factory, transported to the site, and assembled into a complete building using reliable connection methods. It involves the factory fabrication and installation of the main structure, enclosure structure, equipment pipelines, and interior decoration, forming standardized prefabricated modular spaces that are then assembled on-site. With its high efficiency and environmental friendliness, modular building has become an important development direction for modern building industrialization.

[0003] Currently, when modular integrated building units are lowered into place, on-site operators need to use tools such as hands, ropes, or pry bars to assist in positioning. However, due to the large size of the units (a single unit's volume is typically ≥30m³), this process becomes more complex. 3 For heavy loads (single container weight ≥ 15 tons), this type of manual assistance method has significant drawbacks. Manual operation makes it difficult to control the horizontal displacement of the container during descent, especially when wind force ≥ level 4 or the lifting equipment's micro-motion precision is insufficient. The container is prone to shifting or rotating, causing misalignment of the connection holes between the upper and lower containers, requiring repeated lifting and adjustment, severely impacting installation efficiency. Furthermore, once the container is in place, due to its large weight, if the positioning deviation exceeds the allowable range, it is difficult to move and adjust.

[0004] Therefore, there is an urgent need for an installation and positioning device for modular building boxes with high installation efficiency and high installation accuracy. Utility Model Content

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an installation and positioning device for modular building boxes, which solves the technical problems of low installation efficiency and low installation accuracy of the prior art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the main technical solution adopted by this utility model includes: This utility model provides an installation and positioning device for a modular building box, including an upper bowl and a lower cone; in the upper and lower modular building boxes arranged from top to bottom, the upper bowl is installed at the bottom of the upper modular building box, and the lower cone is installed at the top of the lower modular building box, with the installation positions of the upper bowl and the lower cone corresponding vertically; the upper modular building box is installed and positioned by the upper bowl located at its bottom connecting with the lower cone at the top of the lower modular building box.

[0009] Optionally, the upper bowl body includes a positioning groove seat and a plurality of first anchor tail irons; the positioning groove seat is fixed to the bottom of the upper modular building box body by the plurality of first anchor tail irons, and the opening of the positioning groove seat faces downward.

[0010] Optionally, the lower cone includes a positioning cone platform and multiple second anchor tail irons; the positioning cone platform is fixed to the top of the lower modular building box by multiple second anchor tail irons, and the positioning cone platform faces upward to achieve positioning insertion with the positioning slot seat.

[0011] Optionally, the shape of the positioning slot matches the positioning cone; the volume of the positioning slot is greater than the volume of the positioning cone.

[0012] Optionally, the first anchor tail iron is straight in shape; the second anchor tail iron is J-shaped or L-shaped.

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides an installation and positioning device for modular building boxes. Through the structural design of an upper bowl and a lower cone, when the upper integrated box module falls into place and approaches the lower cone, a rough adjustment is made manually to ensure the cone apex is within the bowl's opening range. This operation requires no professional skills or complex tools and can be completed by a single person, completely changing the traditional positioning method's heavy reliance on manpower and tools, significantly reducing the installation threshold and labor costs. As the upper integrated box module continues to fall, once the lower cone enters the bowl's opening, the limiting structure of both will automatically activate. Based on the geometric fit between the upper bowl and the lower cone, and utilizing the horizontal component force generated by the box's own weight, autonomous centering and precise positioning of the box can be achieved without secondary human intervention, completely eliminating the tedious operation of repeatedly raising and lowering the box's position. Compared to existing technologies, this not only reduces the time spent on manual positioning but also avoids rework and repairs caused by inaccurate positioning, significantly improving overall construction efficiency and quality, and providing strong technical support for the large-scale application of modular buildings.

[0028] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0029] Example 1:

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides an installation and positioning device for a modular building box, including an upper bowl 1 and a lower cone 2. In the upper and lower modular building boxes arranged from top to bottom, the upper bowl 1 is installed at the bottom of the upper modular building box, and the lower cone 2 is installed at the top of the lower modular building box. The installation positions of the upper bowl 1 and the lower cone 2 are corresponding vertically. The upper modular building box is installed and positioned by the upper bowl 1 located at its bottom connecting with the lower cone 2 at the top of the lower modular building box.

[0031] Specifically, through the structural design of the upper bowl 1 and the lower cone 2, when the upper integrated box module falls into place and approaches the lower cone 2, a rough adjustment is made manually to ensure that the cone apex is within the bowl opening range. This operation requires no professional skills or complex tools and can be completed by a single person, completely changing the traditional positioning's high dependence on manpower and tools, and significantly reducing the installation threshold and labor costs. As the upper integrated box module continues to fall, once the lower cone 2 enters the bowl opening of the upper bowl 1, the limiting structure of both will automatically function. Based on the geometric fit between the upper bowl 1 and the lower cone 2, and utilizing the horizontal component force generated by the box's own weight, the box can achieve autonomous centering and precise positioning without secondary human intervention, completely eliminating the tedious operation of repeatedly raising and lowering the box position. Compared with existing technologies, this not only reduces the time for manual positioning but also avoids subsequent processes such as rework and repair due to inaccurate positioning, significantly improving overall construction efficiency and quality, and providing strong technical support for the large-scale application of modular buildings.

[0032] Furthermore, such as Figure 1 and Figure 2As shown, the upper basin 1 includes a positioning slot 11 and multiple first anchoring tail irons 12. The positioning slot 11 is fixed to the bottom of the upper modular building box by the multiple first anchoring tail irons 12, and the opening of the positioning slot 11 faces downward. Specifically, the upper basin 1 is engaged with the bottom concrete structure of the upper box by multiple straight first anchoring tail irons 12, with an anchoring length ≥200mm, so that the positioning slot 11 and the box form an integral whole, ensuring uniform load transfer. During prefabrication, the first anchoring tail irons 12 are welded to the bottom of the positioning slot 11 and directly embedded into the box when pouring concrete, avoiding the later drilling and rebar installation process and shortening the factory prefabrication cycle.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, the lower cone 2 includes a positioning cone 21 and multiple second anchoring tail irons 22. The positioning cone 21 is fixed to the top of the lower modular building box by the multiple second anchoring tail irons 22, and the positioning cone 21 is positioned and inserted into the positioning slot seat 11 with its upward facing direction. Specifically, the lower cone 2 is engaged with the concrete structure at the top of the lower box by J-shaped or L-shaped second anchoring tail irons 22. The bent section of the tail iron can expand the stress diffusion area, reduce the local concrete bearing pressure, and avoid stress concentration cracks at the root of the lower cone 2.

[0034] Furthermore, in this embodiment, the ratio of the top diameter to the bottom diameter of the positioning cone 21 is 0.4 to 0.7, and the taper of the positioning cone is 1:1.4 to 2.5. This allows the horizontal component of the force and the weight of the box to reach the optimal balance when it falls. The reasonable taper disperses the impact force at the moment of contact, thus protecting the structure.

[0035] Example 2:

[0036] This embodiment provides an installation and positioning device for a modular building box, including all the structures in Embodiment 1.

[0037] In this embodiment, a composite coating is provided on the inner wall of the positioning slot 11 and the outer surface of the positioning cone 21; the composite coating includes a self-lubricating layer and a buffer layer coated from the outside to the inside. The lubricating layer is a polytetrafluoroethylene (PTFE) or graphene-based coating, which can significantly reduce friction when the box falls, shortening the positioning time. The self-lubricating layer is designed to be 10-30 μm thick to ensure both lubrication effect (friction coefficient remains stable at 0.08-0.12 over a long period) and good adhesion. Furthermore, the buffer layer is a nitrile rubber buffer layer; a 100-200 μm thick nitrile rubber buffer layer can absorb most of the impact energy, preventing concrete cracking caused by rigid collisions.

[0038] Example 3:

[0039] This embodiment provides an installation method for the modular building box installation and positioning device described in Embodiment 1 or 2, including the following steps:

[0040] S1, such as Figure 3 and Figure 4 As shown, a point limiting protrusion 31 (corresponding to the initial single lower cone 2) and a line limiting protrusion 32 (which can represent multiple lower cones 2) are set at the pre-embedded lower cone 2 at the top of each lower modular building box, and their position parameters are determined according to preset standard data: d1 / d2 represents the absolute coordinate position of the point limiting protrusion 31, D / L: represents the relative position between the point limiting protrusion 31 and the line limiting protrusion 32, where D is the horizontal distance between the two and L is the straight distance between the two.

[0041] S2. Using a total station, mark the absolute coordinates (d1, d2) of all lower cones 2 and the relative positions (D, L) of the line limiters on the horizontal steel plate to form a planar positioning network; weld the initial lower cones 2 at the marked absolute coordinate points (d1, d2), and weld multiple lower cones 2 corresponding to the line limit protrusions 32 along the layout straight line according to the spacing parameters D and L.

[0042] S3. Measure the actual coordinates (dx, dy) of the current modular building box limit protrusion 31, and calculate the deviation from the design value (d1, d2): If |dx-d1| ≤ 3mm or |dy-d2| ≤ 3mm, place directly; if the deviation exceeds the tolerance, the box will be checked according to dx ± 3mm or dy ± 3mm, that is, the cumulative deviation of the box on each floor shall not exceed 3mm.
