Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated building, in particular to a prefabricated wall connecting system with error compensation function and a construction method thereof. BACKGROUND

[0002] With the continuous development of prefabricated building technology, prefabricated walls, as an important part of modern buildings, have become a mainstream construction method through factory production and on-site assembly. However, the existing prefabricated wall connecting methods are often affected by construction errors, hoisting precision and other factors, resulting in angle deviation and position error during wall splicing. If these errors cannot be effectively compensated, it will directly affect the safety and stability of the building structure.

[0003] Traditional prefabricated wall connecting methods, such as steel sleeve grouting, bolt connection and socket sleeve, can ensure the strength of wall connection to a certain extent, but most methods require high positioning accuracy and installation operation process. Once installation errors occur, it is easy to cause wall installation difficulties, even damage, and need to be reworked. The current technology mostly uses single-direction flexible gaskets or elastic adjustment, which cannot effectively compensate for errors in three-dimensional space, and the existing locking devices are often fixed only once, lacking adjustability, making it impossible to adjust after installation.

[0004] Therefore, there is an urgent need for a prefabricated wall connecting system that can realize multi-dimensional error compensation, quick docking, adjustment and repeated adjustment to meet the high requirements of prefabricated buildings in terms of precision, reliability and construction efficiency.

[0016] In summary, the application has the following at least one beneficial technical effect: 1.

The construction method of setting a pressure gauge at the grouting outlet for detection is proposed.

DETAILED DESCRIPTION

[0027] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] The embodiments of the present application disclose a prefabricated wall connecting system with error compensation function.

[0029] Reference Figure 1 The prefabricated wall connecting system with error compensation function mainly comprises a first prefabricated wall 1, a second prefabricated wall 2, a connecting mechanism 44 arranged between the two walls, and a pouring formwork 6 (not shown in the figure) arranged between the two walls.

[0030] The first prefabricated wall body 11 is provided with a plurality of prefabricated steel bars 11 embedded along the length direction at intervals, the diameter of the steel bar is preferably 12-20 mm, the grade of the steel bar is HRB400, and the interval is 200-400 mm to ensure the structural bearing capacity. The front surface of the first prefabricated wall body 1 is provided with a pouring port, including a pouring inlet 21 arranged at the lower part and a pouring outlet 22 arranged at the upper part, and the two are diagonally arranged.

[0031] The second prefabricated wall body 2 is provided with a plurality of prefabricated grooves arranged at intervals along the length direction, and each prefabricated groove corresponds to a prefabricated steel bar 11. The diameter of the prefabricated groove is 10-20 mm larger than the diameter of the steel bar, for example, when the diameter of the steel bar is 20 mm, the diameter of the prefabricated groove can be 30-40 mm. The gap ensures that the steel bar can be smoothly inserted even if there is an installation error of ±20 mm horizontally and ±10 mm vertically during the insertion process, and the gap is eliminated and consolidated after subsequent concrete pouring.

[0032] Therefore, the connecting mechanism 4 is arranged between the first prefabricated wall body 1 and the second prefabricated wall body 2, and the connecting mechanism 4 includes a floating connection unit and a locking structure 43. Before pouring, the floating connection unit provides flexible connection between the first prefabricated wall body 1 and the second prefabricated wall body 2, and the locking structure 43 locks the floating connection unit to realize overall consolidation.

[0033] Referring to Figure 2 , a pressure monitoring device 23 is arranged at the pouring outlet 22, which can be a mechanical pressure gauge with a range of 0-1.0 MPa for directly displaying the concrete pressure in the pipeline, or an electronic pressure sensor with a range of 0-1.0 MPa, which outputs an electrical signal and connects a display terminal for real-time monitoring by construction personnel. During pouring, when the detected value reaches 0.3-0.5 MPa, it is confirmed that the concrete has been filled, and pouring is stopped.

[0034] By arranging the pressure monitoring device 23, not only can material waste caused by over-pouring be avoided, but also node hollowing caused by insufficient pouring can be prevented, thereby ensuring the structural quality and construction reliability.

[0035] The floating connection unit includes a first floating connection assembly 41 and a second floating connection assembly 42, which realize multi-dimensional adjustment through ball hinge connection. Specifically, referring to Figure 5 and Figure 6, the first floating connection assembly 41 comprises a first mounting seat 412, a first articulated ball seat 413, a first articulated ball 414 and a first connecting rod 415, wherein the first mounting seat 412 is cylindrical, the first mounting seat 412 is embedded in the first prefabricated wall body 1, and a boss with a diameter larger than that of the first mounting seat 412 is arranged on one side of the first mounting seat 412 in the first prefabricated wall body 1, which plays a role of preventing the first mounting seat 412 from being separated from the first prefabricated wall body 1 and enhances the stability of the connection between the first mounting seat 412 and the first prefabricated wall body 1. The first articulated ball seat 413 is a hollow spherical body coaxially embedded in the first mounting seat 412, the first articulated ball 414 is connected with the first articulated ball seat 413 by a spherical hinge, and one end of the first connecting rod 415 is coaxially welded and fixed with the first articulated ball 414. The second floating connection assembly 42 comprises a second mounting seat 422, a second articulated ball seat 423, a second articulated ball 424 and a second connecting rod 425, and the structure connection can be referred to the first floating connection assembly 41, and the connection principle is the same, which is connected by a spherical hinge, so that the first connecting rod 415 or the second connecting rod 425 can rotate freely within a range of activity.

[0036] As shown in Figure 4 , in order to improve the stability of the connection between the first mounting seat 412 and the second mounting seat 422 and the wall body, two first connecting rods 411 are welded and fixed on the side of the first mounting seat 412 away from the first articulated ball seat 413, and two second connecting rods 421 are welded and fixed on the side of the second mounting seat 422 away from the second articulated ball seat 423. The first mounting seat 412 and the first connecting rod 411 are integrally embedded in the first prefabricated wall body 1, and the second mounting seat 422 and the second connecting rod 421 are integrally embedded in the second prefabricated wall body 2, which greatly increases the contact area with the concrete during pouring of the wall body, and further improves the stability of the installation of the first mounting seat 412 and the second mounting seat 422.

[0037] As shown in Figure 6 , the locking device comprises a locking male head 431 and a locking female head 432 in threaded cooperation. The locking female head 432 is a cylindrical body with an open end, and the end of the locking female head 432 away from the open end is coaxially and slidingly sleeved on the first connecting rod 415. The end of the first connecting rod 415 away from the first articulated ball 414 is provided with a boss, which can limit the locking female head 432 from being separated from the first connecting rod 415. The outer peripheral wall of the locking female head 432 is a regular hexagon, which facilitates screwing and force application. The inner wall is provided with internal threads. The locking male head 431 is cylindrical and coaxially fixedly connected with the second rod body, and the outer peripheral wall is provided with external threads.

[0038] By the threaded cooperation of the two groups of spherical hinges and the locking male head 431 and the locking female head 432, when the first prefabricated wall body 1 and the second prefabricated wall body 2 are misaligned due to production errors or site environmental factors, the angle of the first rod body and the second rod body is adjusted to make the first rod body and the second rod body collinear, as shown in Figure 7As shown, the locking male head 431 and locking female head 432 are then threaded together to achieve multi-dimensional error compensation. After adjustment and locking are completed, concrete is poured to achieve a stable connection between the first precast wall 1 and the second precast wall 2.

[0039] For ease of pouring, refer to Figure 3 and Figure 4 The second precast wall 2 is pre-embedded with a casting pipe 3. The casting pipe 3 includes a casting main pipe 31 arranged horizontally and multiple casting branch pipes 32 arranged vertically. The diameter of the casting main pipe 31 is 50mm and the diameter of the casting branch pipes 32 is 40mm. The multiple casting branch pipes 32 are all connected to the casting main pipe 31 and are spaced apart along the length of the casting main pipe 31. Each casting branch pipe 32 is attached to the corresponding precast groove.

[0040] To further improve the stability of the connection between the walls, in this embodiment, a pouring channel 5 is provided inside the connection mechanism 4 so that concrete flows into the pouring channel 5. After it solidifies, the various components of the connection mechanism 4 are further reinforced.

[0041] Specifically, such as Figure 3 , Figure 4 and Figure 6 As shown, the pouring pipe 3 also includes a locking pouring pipe 33 with a diameter of 25mm. Multiple sets of connecting mechanisms 4 are spaced apart along the length of the first wall. The number of locking pouring pipes 33 is the same as the number of connecting mechanisms 4. In this embodiment, two sets of connecting mechanisms 4 are provided. A pouring channel 5 with a diameter of 8mm is provided in the middle of the connecting mechanism 4 (e.g.,...). Figure 6 As shown), the pouring channel 5 connects the first hinge ball seat 413, the first hinge ball 414, the first connecting rod 415, the locking male head, the second connecting rod 425, the second hinge ball 424, the second hinge ball seat 423, and the second mounting seat 422. Concrete enters the pouring channel 5 through the locking pouring pipe 33 and fills every gap. After the concrete solidifies, the entire connecting mechanism 4 can be fixed.

[0042] Furthermore, both the first hinge ball seat 413 and the second hinge ball seat 423 have locking casting grooves 44 at their ends away from the locking device. The diameter of the locking casting grooves 44 is larger than the diameter of the casting channel 5. In this embodiment, the diameter of the locking casting grooves 44 is three times the diameter of the casting channel 5. Thus, the two locking casting grooves 44 and the casting channel 5 together form an "I"-shaped cavity. After the cavity is filled with concrete, the floating connection unit is further locked, so that the floating connection unit and the cast concrete are integrated and solidified. This strengthening process is an additional tightening effect produced during the casting process between the first precast wall 1 and the second precast wall 2, which solves the problem of loose connection between the connecting parts and the wall and easy loosening later.

[0043] It should be noted that the concrete used in the embodiment is high-flowability and low-viscosity concrete, which is fine aggregate concrete mainly composed of sand, cement, water and additives (such as water reducing agent), and the aggregate particle size is controlled below 5 mm to ensure that it can smoothly pass through the preset pouring pipeline 3 and pouring channel 5.

[0044] The application also discloses a construction method of the prefabricated wall connecting system with error compensation function, which comprises the following steps: S1, installation preparation: hoist the first prefabricated wall 1 comprising a plurality of prefabricated steels 11 arranged at intervals along the length direction and provided with a pouring port on the front surface, and the second prefabricated wall 2 provided with a plurality of prefabricated slots at intervals along the length direction to the predetermined position, so that the plurality of prefabricated steels 11 are roughly aligned with the plurality of prefabricated slots; S2, pre-connection: adjust the floating connecting unit arranged between the first prefabricated wall 1 and the second prefabricated wall 2, so that the first connecting rod 415 and the second connecting rod 425 realize angle compensation under the action of the spherical hinge, and the first connecting rod 415 and the second connecting rod 425 are locked by the locking device to realize the temporary pre-connection of the two prefabricated walls; S3, erecting a template: erect a pouring template between the two prefabricated walls to form a closed pouring cavity; S4, pouring operation: pour concrete into the pouring pipeline 3 and the pouring channel 5 through the pouring inlet 21 of the first prefabricated wall 1 until the concrete seeps out of the pouring outlet 22 and the pressure monitor detects that the predetermined threshold value is reached, and the pouring is terminated; S5, removing the template: after the strength of the poured concrete reaches the design requirement, remove the pouring template to form a pouring layer 6 between the first prefabricated wall 1 and the second prefabricated wall 2, as shown in Figure 8 .

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
