Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated building construction, in particular to a prefabricated building wall construction structure and a construction method. BACKGROUND

[0002] Prefabricated building is a new type of building method that has emerged in recent years, which has attracted attention due to its green, efficient and economical characteristics. As an important innovation in the field of modern architecture, it not only improves the construction efficiency, but also promotes the sustainable development of the construction industry. In view of the problem of penetrating facilities such as air conditioning pipes and range hood pipes in the wall, prefabricated wall designs with reserved holes and grooves have gradually appeared on the market, that is, according to the requirements of building design, the positions of holes and grooves required by air conditioning, range hood pipes and other facilities are accurately reserved during the prefabrication stage of prefabricated building walls, and then the pipes are installed based on the reserved holes and grooves after the completion of building construction.

[0003] Patent "CN 117947889 B" discloses a prefabricated building wall, which has a hole and groove matched with the penetration of the pipe on the assembled wall. By controlling the rotation of the driven ring, the flexible rubber sleeve is in a crimped state to wrap the outer wall of the internal pipe, thereby avoiding the entry of external foreign matter into the room through the gap between the pipe and the hole. However, this scheme still has the following problems: the flexible rubber sleeve is wrapped outside the installed pipe, so when the flexible rubber sleeve is crimped, it has a structure similar to a twisted rope. Although the flexible rubber sleeve can tightly wrap the installed pipe, the gap between the outer side of the flexible rubber sleeve and the inner wall of the reserved hole will be separated from the tight contact state, so that as the degree of crimping of the flexible rubber sleeve increases, the gap between the flexible rubber sleeve and the inner wall of the reserved hole will also increase. In addition, this scheme only seals the hole on the inside of the wall, i.e. the indoor part, and does not seal the hole on the outside, so that over a long period of use, external foreign matter will inevitably enter the gap, erode the rubber sleeve and enter the room, affecting the comfort and hygiene of the living environment.

DETAILED DESCRIPTION

[0034] The application will be further described in detail below in combination with the drawings and specific embodiments:

[0035] The embodiment 1 aims to provide a prefabricated building wall construction structure, which is mainly used for plugging the two sides of the reserved hole of the prefabricated wall. According to the building design requirements, the required hole and groove positions of air conditioners, exhaust hood pipes and the like are reserved on the prefabricated wall in advance, which not only simplifies the construction process, improves the construction efficiency, but also reduces the risk of falling objects from high altitude, ensures the overall strength of the wall, and solves the problems of the prior art, such as the sealing is not strict, the sealing isolation of the two sides of the inner and outer walls cannot be guaranteed, and the living environment is affected. The embodiment provides a prefabricated building wall construction structure, which can ensure that the reserved hole of the wall can form an effective double sealing barrier after the pipe is installed, prevent external foreign matters from entering the room through the gap between the pipe and the hole, and enhance the overall heat insulation performance of the wall, while considering the convenience of construction and the simplicity of later maintenance.

[0036] As shown in Figures 1-3 , a prefabricated building wall construction structure includes a tightening assembly and a driving assembly, wherein the tightening assembly includes a connecting pipe 1, an inner conical body 3, a fixed shaft seat 4, an outer sliding sleeve 5, an outer conical body 6, an inner sliding sleeve 7 and a central shaft 9. The connecting pipe is a connecting pipe body of an air conditioner, an exhaust hood or the like, both ends of the pipe body can be used for line assembly connection, and the diameter of the connecting pipe is measured and recorded in advance. Referring to Figure 3 , the fixed shaft seat 4 is fixedly sleeved on the outer periphery of the connecting pipe, and the central shaft 9 is rotatably sleeved in the fixed shaft seat. In the embodiment, three central shafts are matched and sleeved on the fixed shaft seat, and the number of central shafts can be adaptively adjusted according to the site condition in actual application.

[0037] The inner and outer ends of the central shaft are respectively provided with an inner threaded section 16 and an outer threaded section 17. The inner conical body and the outer conical body are respectively arranged at the inner and outer ends of the central shaft, and are matched and sleeved on the connecting pipe on the inner and outer sides of the fixed shaft seat. The inner conical body extends outward along the horizontal direction to form the inner sliding sleeve 7, and the outer conical body extends inward along the horizontal direction to form the outer sliding sleeve 5. The inner sliding sleeve 7 and the outer sliding sleeve 5 are matched and threadedly connected on the inner threaded section 16 and the outer threaded section 17.

[0038] As shown in Figure 4 and Figure 5 , the inner end of the central shaft penetrates through the inner sliding sleeve and is in transmission connection with the driving assembly inside the inner conical body. The outer end of the central shaft is sleeved in the outer sliding sleeve, and a space allowance is left between the outer threaded section end of the central shaft and the bottom of the inner cavity of the outer sliding sleeve. When the central shaft rotates, the outer sliding sleeve can slide a certain distance along the axial extension direction of the central shaft through the thread cooperation between the outer sliding sleeve and the outer threaded section.

[0039] Further, as shown in Figure 5As shown, the opening of the outer sliding sleeve 5 faces the inner side, and the outer bottom is provided with a connecting shaft 10 in the horizontal direction, and the outer conical body is provided with a mounting hole matched with the connecting shaft, so that the outer conical body is matched and sleeved on the connecting shaft, and the outer end surface of the connecting shaft is threaded, and when the outer conical body is matched and sleeved on the connecting shaft, the position of the outer conical body can be locked by screwing the nut 11. Figure 5 As shown, the opening of the inner sliding sleeve 7 faces the outer side, and the center shaft penetrates the inner conical body in the horizontal direction and is sleeved and fixed with the coupling 15 on the inner side of the inner conical body.

[0040] In this embodiment, when the center shaft is driven to rotate, the inner and outer sliding sleeves move axially along the center shaft through the cooperation of the inner and outer sliding sleeves with the threaded segments on both sides of the center shaft, thereby driving the inner and outer conical bodies to move towards or away from each other, so that the inner and outer sides of the inner and outer conical bodies are in close contact with the inner and outer openings of the wall body reserved hole slot, and the clamping force and plugging degree of the assembled wall reserved hole can be gradually tightened or loosened during the movement of the two, thereby realizing the sealing and plugging adjustment of the assembled wall reserved hole.

[0041] As shown in Figure 3 and Figure 6 As shown, the driving assembly includes a fixed plate 2, a gear ring 12 and a gear 13, wherein the center hole of the fixed plate is provided with a center hole, the inner diameter of the center hole is matched with the outer diameter of the connecting pipe 1 of the external device to be installed, and the connecting pipe is matched and penetrated, the outer periphery of the center hole of the fixed plate is provided with a support frame 18, the support frame is triangular in structure and is rotatably sleeved with a plurality of rotating shafts 14 in the circumferential direction, the gear 13 is correspondingly fixedly sleeved on the inner side of the rotating shaft, and the outer side of each gear is matched and engaged with the gear ring for transmission, and the connecting pipe is sleeved on the middle part of the gear. Figure 3 As shown, a lever 20 is further provided on the front side wall of the gear ring, and the rotation of the gear ring can be driven by pulling the lever.

[0042] When the gear ring is driven to rotate, the rotation of each gear can be driven, thereby driving the corresponding rotating shaft in the gear to rotate. The outer side of the rotating shaft extends out of the support frame and is sleeved and fixed with the coupling on the fixed plate, that is, the inner side of the coupling 15 is sleeved and fixed with the rotating shaft, and the outer side of the coupling is sleeved and fixed with the center shaft 9, so that when the rotating shaft rotates, the center shaft can be simultaneously driven to rotate, thereby driving the inner and outer conical bodies to move towards or away from each other.

[0043] Working principle explanation; the assembled building wall construction structure provided in this embodiment is actually constructed, as shown in Figure 8As shown, according to design requirements, holes and grooves required for air conditioners, exhaust fans and the like are reserved on the wall. In the initial state, the inner and outer conical bodies are located on the inner and outer sides of the hole and groove (i.e. indoor and outdoor), that is, the outer side of the inner conical body is in contact with the inner side of the reserved hole and groove, and the inner side of the outer conical body is in contact with the outer side of the reserved hole and groove. The inner and outer sleeves are connected to the inner and outer threaded segments of the central shaft by threads, but are not completely tightened. When the wiring is completed and the external equipment is installed, the reserved hole and groove are sealed, thereby manually rotating the gear ring. The gear ring 12 is in meshing transmission with the plurality of gears 13, driving the gears to rotate synchronously, and the gears drive the central shaft to rotate synchronously through the shaft coupling. When the central shaft rotates, the inner and outer threaded segments are in threaded cooperation with the inner and outer sleeves 7 and 5, respectively, to produce axial movement. That is, according to the size of the hole, the conical inclined surfaces on the inner and outer conical bodies will slide along the hole opening respectively as they move axially. Their opposite movement will gradually tighten the clamping force on the hole and groove. With the increase of the clamping force, the inner and outer conical bodies are tightly fitted with the inner and outer openings of the wall reserved hole and groove, achieving adaptation to the hole and forming an effective sealing barrier. When the desired sealing effect is achieved, the position of the outer conical body can be locked by rotating the nut 11 to prevent it from loosening during use.

[0044] The construction structure provided by the embodiment not only achieves direct sealing of the hole and groove through the clamping force of the inner and outer conical bodies, but also forms a double sealing barrier through their tight fitting with the wall reserved hole and groove. By adjusting the rotation direction and amount of the gear ring, the movement distance and clamping force of the inner and outer conical bodies can be accurately controlled, thereby adjusting the sealing degree and adaptation degree of the hole and groove. This not only prevents external foreign matter from entering the room through the gap between the pipe and the hole and groove, but also enhances the overall thermal insulation performance of the wall. The connection between the components is tight and easy to disassemble and replace, greatly improving the convenience of construction and the simplicity of later maintenance.

[0045] In Embodiment 2, on the basis of Embodiment 1, a limiting assembly is provided for limiting the position of the gear ring.

[0046] As shown in Figure 9 The limiting assembly includes a protective sleeve 8, a top spring 22 and a top head 23, etc. The protective sleeve is fixedly connected to the fixed plate by a through bolt and is hollow inside, sleeving the outside of the gear ring and having an opening on the inside for the connecting pipe to pass through. The protective sleeve can coat the gear ring. There is also an annular groove 21 on the side wall adjacent to the circumferential side of the gear ring inside the protective sleeve, and the top spring 22 is uniformly fixed in the annular groove. The free end of the top spring is fixedly connected to the top head 23, the outer end of which is an arc-shaped end 24, and the arc-shaped ends all face the direction of the outer side wall of the gear ring. As shown in Figure 9As shown, the gear ring is also provided with an arc-shaped limiting ring groove 25 on the circumference, which matches the arc-shaped end of the top head.

[0047] The left side of the protective sleeve is provided with an arc-shaped groove matching the outer diameter of the push rod, and the push rod can move along the circumference in the arc-shaped groove, so that the gear ring can be pushed to move axially relative to the internal gear by pushing the push rod on the gear ring. When it is necessary to rotate the gear ring to drive the central shaft to rotate, the movement of the gear ring by the push rod, the top head extends to the gear ring direction under the natural state of the top spring, so that when the top head is located in the arc-shaped ring groove on the gear ring, the top head and the gear ring are in a separated state, and the arc-shaped end of the top head does not contact the gear ring, so that when the gear ring is driven to rotate, the top head always remains in the extended state and will not be affected by the rotation of the gear ring.

[0048] When the inner and outer conical bodies block the reserved hole slot opening on the assembled wall, the gear ring is moved away from the fixed plate by the push rod, so that the top head moves out of the limiting ring groove on the gear ring, and the compression spring is compressed. Under the action of the circumferentially distributed compression spring, each top head presses the gear ring inward, so that the key position of the gear ring is fixed, thereby avoiding the rotation of the gear and the position of the inner and outer conical bodies is locked. In addition, it should be noted that the compression spring used in this embodiment has a sufficient spring constant to lock the position of the gear ring to prevent unnecessary rotation, and the gear ring is always located inside the protective sleeve during the forward and backward sliding process.

[0049] When the inner and outer conical bodies block the reserved hole slot opening on the assembled wall, the gear ring is moved away from the fixed plate by the push rod, so that the top head moves out of the limiting ring groove on the gear ring, and the compression spring is compressed. Under the action of the circumferentially distributed compression spring, each top head presses the gear ring inward, so that the key position of the gear ring is fixed, thereby avoiding the rotation of the gear and the position of the inner and outer conical bodies is locked. In addition, it should be noted that the compression spring used in this embodiment has a sufficient spring constant to lock the position of the gear ring to prevent unnecessary rotation, and the gear ring is always located inside the protective sleeve during the forward and backward sliding process.

[0050] In Embodiment 3, on the basis of Embodiments 1 and 2, a construction method of the assembled building wall construction structure is provided, comprising the following steps:

[0051] Step 1: According to the building design requirements, the hole slot positions required for air conditioners, range hood pipes and the like are pre-prepared on the assembled wall; the construction structure is passed through the hole slots pre-prepared on the wall, and it is ensured that both ends thereof can be used for line assembly connection;

[0052] Step 2: The outer cone is sleeved on the connecting shaft of the outer sliding sleeve, and the inner side of the outer cone is in contact with the outer side of the outer sliding sleeve, and the nut is locked;

[0053] Step 3: Manually rotate the gear ring, drive each gear and the rotating shaft to rotate synchronously through the meshing transmission of the gear ring and the gear, and then make the inner sliding sleeve and the outer sliding sleeve move axially along the central shaft, and drive the inner cone and the outer cone to move towards each other, gradually tighten the clamping force on the hole groove, and as the clamping force increases, the inner cone and the outer cone are tightly fitted with the inner and outer openings of the wall reserved hole groove, effectively sealed;

[0054] Step 4: After the inner and outer openings of the reserved hole groove are sealed, the gear ring is moved forward by the push rod, and the end position of the gear ring is firmly locked by the inward pressure of each top head, ensuring the stability of the sealing effect;

[0055] Step 5: After the above construction structure is installed, the line connection work inside and outside the wall is completed, the external equipment such as air conditioner and exhaust hood is installed, and it is ensured that they are correctly connected with the line of the connecting pipe.

[0056] The above-mentioned embodiments of the present application do not constitute a limitation on the scope of protection of the present application, and the basic concept of the present application is to provide an efficient and self-adaptive fabricated building wall construction structure to simplify the plugging process of the wall reserved hole groove and ensure the sealing effect. The structure realizes double sealing through the movement of the inner and outer cones, uses the gear transmission system driven by the gear ring to control the axial movement of the central shaft and the cone, automatically adapts to different hole groove sizes, realizes tight fitting and effective sealing, and sets a locking mechanism to ensure the stable position of the cone and the durability of the sealing. Any modification, equivalent replacement and improvement within the spirit and principles of the present application should be included in the protection scope of the claims of the present application.
