Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a prefabricated installation node structure and prefabricated module. Background Technology

[0002] In the process of assembling a prefabricated module, the traditional method for connecting two adjacent prefabricated shear walls involves using aluminum formwork combined with tie rods to connect the two prefabricated wall panels before pouring concrete. During construction, holes are first drilled in the prefabricated wall panels, then the aluminum formwork is placed at the connection point between the two prefabricated wall panels. Tie rods are then passed through the aluminum formwork and the holes to fix and support the aluminum formwork to the two prefabricated wall panels. Concrete is then poured into the space enclosed by the aluminum formwork and the two prefabricated wall panels to connect them. After the concrete has reached a certain strength, the aluminum formwork and tie rods are removed, and the holes are sealed. The problems with this method are: due to the influence of processing precision, the alignment accuracy between the holes in the prefabricated wall panels and the holes in the aluminum formwork is poor, increasing installation difficulty. Holes in the prefabricated shear walls also affect the structural integrity of the prefabricated shear walls, thus affecting the stability and durability of the structure. Furthermore, the loading and unloading process of the aluminum formwork and tie rods is cumbersome and complex, increasing construction procedures and operational difficulty, leading to decreased construction efficiency. Meanwhile, after the holes in the precast shear wall are sealed, there is a risk of water seepage due to poor sealing quality or long-term use, which affects the waterproofing effect and thus threatens the long-term structural durability.

[0007] In the first aspect, this utility model embodiment provides a prefabricated installation node structure, including a first embedded part and a second embedded part that can be pre-embedded into two prefabricated shear walls respectively, a clamping part fixed to the first embedded part, and a backstop part fixed to the second embedded part;

[0008] The clamping member includes a clamping body with an opening at the upper end and at one end away from the first embedded part, and at least two elastic locking tongues that are disposed opposite to each other inside the clamping body and can be bent outward.

[0009] The anti-reverse component is provided with a limiting surface facing the second embedded component;

[0010] When the anti-reverse member is inserted downward into the opening of the clamping body, at least a portion of the anti-reverse member can be inserted into the space enclosed by at least two elastic locking tongues, and the free end of the elastic locking tongue can press against the limiting surface.

[0011] According to this utility model, the clamping body is horizontally oriented, and a horizontally extending elongated hole is formed in the peripheral wall of the clamping body;

[0012] The connecting end of the elastic locking tongue is integrally connected to the end of the elongated hole away from the first embedded part, and extends inwardly towards the first embedded part.

[0013] The free end of the elastic locking tongue extends horizontally along the centerline of the clamping body.

[0014] According to this utility model, the vertical cross-section of the clamping body is U-shaped;

[0015] The elastic locking tongue is provided on both opposite sides of the clamping body; or,

[0016] The elastic locking tongue is provided on both sides and the bottom of the clamping body.

[0017] According to this utility model, the clamping body includes two plates arranged opposite to each other, and both plates are provided with the elastic locking tongue; or...

[0018] The clamping body includes two plates arranged opposite each other and a plate located below the two plates arranged opposite each other, and each plate is provided with the elastic locking tongue.

[0019] According to this utility model, the anti-reverse component includes a horizontally oriented base and an end head, with the second embedded component and the end head respectively fixedly connected to both ends of the base;

[0020] The end face that connects to and protrudes from the base is the limiting surface;

[0030] (III) Beneficial Effects

[0031] The beneficial effects of this utility model are as follows: The prefabricated installation node structure of this utility model, through the insertion method between the clamping member and the anti-reverse member, can achieve horizontal tension locking between the clamping member and the anti-reverse member, thereby achieving horizontal tension locking between the two precast shear walls. This counteracts the horizontal compressive force exerted on the two precast shear walls after the expansion of the concrete subsequently poured between them, preventing them from being pulled apart. Simultaneously, this downward insertion installation method reduces the difficulty of alignment and simplifies operation, thus improving work efficiency. Furthermore, the outward bending design of the elastic locking tongue allows the anti-reverse member to shift relative to the elastic locking tongue when horizontal displacement occurs during the downward insertion of the anti-reverse member into the clamping body. The elastic locking tongue can then bend back and press against the limiting surface of the adjusted anti-reverse member, reducing the precision requirements for insertion alignment and lowering the processing and installation difficulty. Moreover, this prefabricated installation node structure does not require drilling holes in the precast shear wall, thus avoiding the impact of holes on the integrity, stability, and durability of the precast shear wall.

[0042] 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" and "lower" are used interchangeably with... Figure 1 The orientation is used as a reference.

[0043] See Figure 1-5 The present invention proposes a prefabricated installation node structure, which includes a first embedded part 1 and a second embedded part 2 that can be pre-embedded in two prefabricated shear walls respectively, a clamping part 3 fixed to the first embedded part 1, and a backstop part 4 fixed to the second embedded part 2.

[0044] The clamping member 3 includes a clamping body 31 with an opening at the upper end and at the end furthest from the first embedded part 1, and at least two elastic locking tongues 32 that are disposed opposite to each other inside the clamping body 31 and are capable of bending outwards. The anti-reverse member 4 is provided with a limiting surface 421 facing the second embedded part 2. It should be noted that the outward bending of the elastic locking tongues 32 means that the elastic locking tongues 32 bend towards the outside of the clamping member 3.

[0045] When the anti-reverse member 4 is inserted into the clamping body 31 through the opening, at least part of the anti-reverse member 4 can be inserted into the space enclosed by at least two elastic locking tongues 32, and the free end of the elastic locking tongue 32 can press against the limiting surface 421.

[0046] It should be noted that when the anti-reverse member 4 is inserted downward into the opening of the clamping body 31 and a horizontal offset occurs, the anti-reverse member 4 is inserted entirely into the space enclosed by at least two elastic locking tongues 32. At this time, the anti-reverse member 4 can be pushed towards the clamping member 3, causing the anti-reverse member 4 to press against the elastic locking tongues 32, causing the elastic locking tongues 32 to bend outward and shift. When the anti-reverse member 4 moves to the limiting surface 421 and disengages from the elastic locking tongues 32, the elastic locking tongues 32 can bend inward and return to their original position, pressing against the limiting surface 421 from their free end.

[0047] When the anti-reverse member 4 is inserted downward into the opening of the clamping body 31 without horizontal displacement, part of the anti-reverse member 4 is inserted into the space enclosed by at least two elastic locking tongues 32. At this time, the limiting surface 421 of the anti-reverse member 4 corresponds to the elastic locking tongue 32, and the free end of the elastic locking tongue 32 can press against the limiting surface 421.

[0048] Therefore, by using the insertion method between clamping member 3 and anti-retraction member 4, horizontal tension locking between clamping member 3 and anti-retraction member 4 can be achieved, thereby achieving horizontal tension locking between the two precast shear walls. This counteracts the horizontal compressive force exerted on the two precast shear walls after the expansion of the concrete subsequently poured between them, preventing them from being pulled apart. Simultaneously, this downward insertion installation method reduces alignment difficulty and simplifies operation, improving work efficiency. Furthermore, the outward bending design of the elastic locking tongue 32 allows the anti-retraction member 4 to shift relative to the elastic locking tongue 32 when horizontal displacement occurs during the downward insertion of the anti-retraction member 4 into the clamping body 31. The elastic locking tongue 32 can then bend back and press against the limiting surface 421 of the adjusted anti-retraction member 4, reducing the precision requirements for insertion alignment and lowering processing and installation difficulty. Moreover, this prefabricated installation node structure does not require drilling holes in the precast shear walls, thus avoiding the impact of holes on the integrity, stability, and durability of the precast shear walls.

[0049] Specifically, the first embedded part 1 and the second embedded part 2 are both integral or welded rigid structural parts to ensure the strength of the clamping part 3 and the anti-reverse part 4 that they connect and support.

[0050] Preferably, both the first embedded part 1 and the second embedded part 2 are I-beams. Since I-beams have different thicknesses, they can be used to embed into precast shear walls of different thicknesses.

[0051] Furthermore, the clamping body 31 is horizontally oriented, and an elongated hole 311 is formed on the peripheral wall of the clamping body 31, extending horizontally in a direction perpendicular to the first embedded part 1.

[0052] The connecting end of the resilient latch 32 is integrally connected to the end of the elongated hole 311 away from the first embedded part 1, and extends inwardly towards the first embedded part 1. The elongated hole 311 and the resilient latch 32 are configured in the above-described shape so that the resilient latch 32 can bend outward.

[0053] The free end of the elastic locking tongue 32 extends horizontally along the center line of the clamping body 31 to better press against the limiting surface 421.

[0054] Furthermore, the structure of the clamping body 31 includes the following two configuration methods:

[0055] The first setting method is: the vertical cross section of the clamping body 31 is U-shaped.

[0056] Both sides of the clamping body 31 are provided with elastic locking tongues 32; or,

[0057] Elastic locking tongues 32 are provided on both sides and at the bottom of the clamping body 31.

[0058] The second configuration is as follows: the clamping body 31 includes two plates arranged opposite each other, and both plates are provided with elastic locking tongues 32; or...

[0059] The clamping body 31 includes two first plates arranged opposite each other and a second plate located below the two first plates arranged opposite each other. Both the first plate and the second plate are provided with elastic locking tongues 32.

[0060] Both of the above-described methods of clamping body 31 ensure that when the anti-retracting member 4 is inserted downward into the opening of clamping body 31, the space enclosed by multiple elastic locking tongues 32 accommodates the anti-retracting member 4 and presses against the limiting surface 421, thereby increasing the number of pressing points between the elastic locking tongues 32 and the limiting surface 421, and thus increasing the tensile locking force between them. Preferably, the clamping body 31 adopts the first configuration to reduce the number of structures and facilitate the fixed connection between the clamping body 31 and the first embedded member 1. More preferably, in the first configuration, elastic locking tongues 32 are provided on both sides and the bottom of the clamping body 31 to simultaneously press and lock against both sides and the bottom of the limiting surface 421, and the elastic locking tongue 32 at the bottom assists in supporting the anti-retracting member 4, further improving the tensile locking force between them.

[0061] Preferably, the clamping member 3 is made of iron, so as to form an elastic locking tongue 32 on the clamping body 31 and ensure the compressive strength and elasticity of the elastic locking tongue 32.

[0062] Furthermore, the anti-reverse component 4 includes a horizontally oriented base 41 and an end 42, with the two ends of the base 41 respectively fixedly connected to the second embedded component 2 and the end 42.

[0063] The end face of the end 42 that is connected to and protrudes from the base 41 is the limiting surface 421.

[0064] Preferably, when at least a portion of the anti-retractor 4 is inserted into the space enclosed by at least two elastic latches 32, there is a gap between the peripheral wall of the base 41 and each elastic latch 32 to reduce the difficulty of processing and insertion. More preferably, the gap is 4 mm.

[0065] Preferably, the limiting surface 421 of the end 42 is recessed inward so that when the elastic locking tongue 32 presses against the limiting surface 421, the elastic locking tongue 32 is locked in the limiting surface 421, thus preventing the elastic locking tongue 32 from disengaging from the limiting surface 421.

[0066] Preferably, the end 42 is hemispherical so that it is horizontally offset during the process of the anti-reverse member 4 being inserted downward into the clamping body 31, causing the elastic locking tongue 32 to not correspondingly press against the limiting surface 421. When the anti-reverse member 4 needs to be pushed horizontally towards the clamping member 3, the friction between the peripheral wall of the anti-reverse member 4 and the elastic locking tongue 32 is reduced, so that the smooth peripheral wall of the anti-reverse member 4 can move relative to the elastic locking tongue 32 and squeeze the elastic locking tongue 32.

[0067] Preferably, the anti-reverse component 4 is a casting to facilitate the forming of the base 41 and the end 42.

[0068] Preferably, the prefabricated installation node structure also includes an annular anti-collision pad.

[0069] The anti-collision pad is fitted onto the base 41 and housed within the limiting surface 421. The tail of the elastic locking tongue 32 presses against the anti-collision pad to prevent the elastic locking tongue 32 from directly rubbing against the limiting surface 421 and causing damage to both.

[0070] More preferably, the anti-collision pad is a plastic anti-collision pad.

[0071] Furthermore, one end of the clamping body 31 is vertically fixed to one end of the first embedded part 1, and the center of one end of the clamping body 31 corresponds to the center of one end of the first embedded part 1, thereby improving the alignment and installation accuracy of the clamping body 31 and the first embedded part 1. One end of the base 41 is vertically fixed to one end of the second embedded part 2, and the center of one end of the base 41 corresponds to the center of one end of the second embedded part 2, thereby improving the alignment and installation accuracy of the base 41 and the second embedded part 2. This ensures the insertion and alignment accuracy between the clamping part 3 and the anti-retraction part 4.

[0072] More specifically, the clamping body 31 is welded to the first embedded part 1, and the base 41 is welded to the second embedded part 2.

[0073] Example 2

[0074] Based on Embodiment 1, this embodiment also provides a prefabricated module, which includes the prefabricated installation node structure of Embodiment 1 and a prefabricated shear wall.

[0075] Two precast shear walls are arranged in parallel relative to each other. Clamping member 3 and anti-retraction member 4 extend from the opposite side of the corresponding precast shear walls so that the two precast shear walls can be connected to each other through clamping member 3 and anti-retraction member 4. Concrete can be poured between the two precast shear walls after connection to form a prefabricated module.

[0076] Specifically, the side of the first embedded part 1 connected to the clamping part 3 and the side of the second embedded part 2 connected to the anti-reverse part 4 are both flush with the surface of the corresponding precast shear wall, so that the clamping part 3 and the anti-reverse part 4 both extend out of the opposite side of the corresponding precast shear wall.

[0077] Furthermore, the first embedded part 1 and the second embedded part 2 are both fixed at the defined positions of the steel mesh in the corresponding precast shear wall to accurately position the first embedded part 1 and the second embedded part 2 relative to the corresponding precast shear wall, thereby improving the docking accuracy between the clamping part 3 on the first embedded part 1 and the anti-reverse part 4 on the second embedded part 2.

[0078] Furthermore, the construction steps for this prefabricated module are as follows:

[0079] S1. Fix the first embedded part 1 and the second embedded part 2 to the two steel meshes respectively, and pour concrete to form a precast shear wall, and ensure that the side of the first embedded part 1 with clamping part 3 and the side of the second embedded part 2 with anti-reverse part 4 are flush with the surface of the precast shear wall.

[0080] S2. The surfaces of the two precast shear walls are washed with water to expose the side of the first embedded part 1 where the clamping part 3 is installed and the side of the second embedded part 2 where the anti-reverse part 4 is installed.

[0081] S3. After aligning and fitting the center of one end of the clamping member 3 with the center of one side of the first embedded part 1, weld one end of the clamping member 3 to one side of the first embedded part 1.

[0082] S4. After aligning and fitting one end of the base 41 of the anti-reverse component 4 with the center of one side of the second embedded component 2, weld one end of the base 41 to one side of the second embedded component 2.

[0083] S5. During construction, first hoist one precast shear wall with the first embedded part 1, then hoist another precast shear wall with the second embedded part 2. When the height distance between the anti-reverse part 4 and the clamping part 3 on the first precast shear wall is approximately 200mm, align the anti-reverse part 4 with the upper opening of the clamping part 3, and continue to hoist the other precast shear wall downwards so that the anti-reverse part 4 is inserted into the opening of the clamping part 3. After the anti-reverse part 4 is embedded in the clamping part 3, pull the other precast shear wall away from the first precast shear wall to drive the limiting surface 421 of the anti-reverse part 4 to press against and lock the elastic locking tongue 32, so that the two precast shear walls are connected to each other through the clamping part 3 and the anti-reverse part 4.

[0084] S6. Concrete can be poured between the two precast shear walls after connection to form a prefabricated module.
