Description

Technical Field

[0001] This invention relates to the field of modular box-type pipe connection technology, and in particular to a quick connection structure for upper and lower pipes of a modular box. Background Technology

[0002] In modular construction, the connection of vertically running pipes is a critical process when prefabricated electromechanical enclosures (such as equipment rooms and pipe shafts) are stacked and installed on-site. The closest existing technology typically uses the traditional "pre-drilled holes + on-site welding / flange connection" method. Specifically, holes are pre-drilled at corresponding positions on the top plate of the lower enclosure and the floor slab of the upper enclosure. After hoisting into place, the upper and lower pipe sections are aligned at the holes and fastened together on-site by welding or using flanges and bolts. Finally, sealant or water-stop rings are filled into the gaps between the pipes and the floor slab holes.

[0003] Existing modular box-type pipe connections have the following drawbacks: First, they require multiple processes on-site, including cutting, welding, and bolt tightening, relying on professional welders and pipe fitters. Connecting a single pipe is time-consuming, completely failing to leverage the core advantage of "rapid assembly" in modular construction and becoming a bottleneck restricting construction speed. Second, they lack deformation adaptability, employing rigid connections that cannot accommodate micro-deformations caused by building settlement, temperature variations, or seismic forces. After long-term use, stress cracks can easily occur at the joints, leading to sewage leaks and contaminating the building's interior environment. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings mentioned above by providing a quick connection structure for the upper and lower pipes of a modular box, which achieves the advantages of rapid connection and deformation adaptability.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a quick connection structure for upper and lower pipes of a modular box, comprising: Drainage pipes, there are two drainage pipes, which are respectively installed on the bottom plate of the upper box and the top plate of the current box; A corrugated hose, the bottom end of which is sealed to the top end of the drain pipe of this layer; A quick-connect structure is provided at the joint between the upper and lower housings to achieve a sealed connection between the bottom of the upper drain pipe and the top of the corrugated hose. A sleeve is disposed on the shelf and fitted onto the surface of the drain pipe.

[0006] Furthermore, the quick-connect structure is a socket-type quick-connect structure, comprising: A socket joint, wherein the socket joint is disposed at the top end of the corrugated hose; A pre-embedded waterstop joint is embedded in the upper layer plate, and the bottom end of the pre-embedded waterstop joint is inserted into the socket joint. The annular gap between the socket joint and the pre-embedded waterstop is filled with quick-drying adhesive.

[0007] Furthermore, the inner wall of the socket joint is provided with an annular groove, and an annular sealing ring is embedded in the annular groove.

[0008] Furthermore, the quick-connect structure is a flange-clamping connection structure, comprising: A circular ring, wherein the circular ring is disposed at the bottom end of the upper drainage pipe; Flange rings are disposed at both ends of the corrugated hose; Guide plates, wherein there are multiple guide plates, and all multiple guide plates are disposed on the surface of the ring, for guiding the flange ring to be coaxially aligned with the ring; The column is a plurality of columns, and all columns are set on a circular ring and correspond to the flange holes on the flange ring surface; An adjusting screw, wherein there are a number of adjusting screws, which are symmetrically rotatably mounted on a ring; Mounting frame, which is screwed onto the surfaces of two adjusting screws; Two pressure plates are symmetrically and rotatably mounted on the mounting frame.

[0009] Furthermore, the guide plate is an arc-shaped plate, and multiple guide plates are arranged in a ring, with the spacing between two relative guide plates being the same as the outer diameter of the flange ring.

[0010] Furthermore, the number and position of the columns correspond one-to-one with the number and position of the flange holes on the flange ring.

[0011] Furthermore, the surface of the mounting frame has two mounting grooves, and the pressure plate is rotatably disposed within the mounting grooves.

[0012] Furthermore, the pressure plate includes a frame and a pressure plate body disposed on the frame. The pressure plate body is a fan-shaped plate, and the surface of the pressure plate body is provided with through holes corresponding to the columns.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please see Figure 1-2 This invention discloses a quick-connect structure for upper and lower pipes of a modular housing, comprising: Drainage pipe 1, there are two drainage pipes 1. The upper drainage pipe 1 is embedded in the reinforced concrete bottom slab of the upper modular box, and its lower end is a narrow plug end. The lower drainage pipe 1 is embedded in the reinforced concrete top slab of the modular box. The corrugated hose 2 has its bottom end sealed to the top of the drain pipe 1 on this floor via a stainless steel clamp. The corrugated hose 2 adopts a forward and reverse design, that is, one end is the forward interface for connecting to the drain pipe 1, which can be an external thread or a socket, and the other end is designed as a reverse interface, which is an internal thread or a plug corresponding to the forward interface. This design allows it to adapt to the connection requirements of different directions in narrow spaces, while maintaining the characteristics of narrow axial width and radial flexibility. Quick connection structure 3 is set at the splicing point of the upper and lower boxes to achieve a sealed connection between the bottom end of the upper drain pipe 1 and the top end of the corrugated hose 2. Quick-connect structure 3 is a socket-type quick-connect structure, including: Socket joint 31 is disposed at the top end of the corrugated hose 2; Pre-embedded waterstop section 32 is pre-embedded in the upper layer plate. The pre-embedded waterstop section 32 is pre-embedded in the reserved hole in the top plate of the lower box body, with waterstop wing ring, and is integrally formed with concrete to provide fixed positioning and basic waterproofing. The bottom end of the upper drainage pipe 1 is inserted into the top end of the pre-embedded water-stop joint 32 and sealed by adhesive. The bottom end of the pre-embedded water-stop joint 32 is inserted into the socket joint 31. The annular gap between the socket joint 31 and the pre-embedded water-stop joint 32 is filled with quick-drying adhesive, and the permanent seal is completed after curing. Furthermore, the bottom surface of the pre-embedded waterstop joint 32 is provided with external threads, and the top inner surface of the socket joint 31 is provided with internal threads that match the external threads. During connection, Teflon tape or thread sealant is wrapped around the threaded part, and mechanical connection and initial sealing can be achieved by rotating and tightening. The inner wall of the socket joint 31 is provided with an annular groove, and an annular sealing ring is embedded in the annular groove to improve the sealing performance of the connection. Sleeve 4 is installed on the top plate of this floor and is fitted onto the surface of drain pipe 1.

[0019] The installation method in this embodiment is as follows: 1. Factory prefabrication: When prefabricating the upper modular box, the pre-embedded water-stop joint 32 is bonded to the upper drainage pipe 1 and then pre-embedded in the corresponding design position of the bottom plate; when prefabricating the current modular box, the current drainage pipe 1 and the protective sleeve 4 are pre-embedded together in the design position of the top plate, and the bottom end of the corrugated hose 2 is sealed to the top end of the current drainage pipe 1 with stainless steel clamps, and the socket joint 31 is fixed to the top end of the corrugated hose 2.

[0020] 2. On-site hoisting: After the modular box is hoisted into place, move the position of the socket joint 31 so that the embedded water stop 32 is aligned with the center of the socket joint 31, and insert the bottom end of the embedded water stop 32 into the inner cavity of the socket joint 31. During the insertion process, the sealing ring is interference-fitted with the outer wall of the embedded water stop 32 to form the first seal.

[0021] 3. Adhesive sealing: Quick-drying adhesive is injected into the annular gap between the socket joint 31 and the pre-embedded waterstop joint 32. After the adhesive cures, a second seal is formed, completing the pipe connection.

[0022] Example 2: Please see Figure 3-5 This invention discloses a quick-connect structure for upper and lower pipes of a modular housing, comprising: Drainage pipe 1, there are two drainage pipes 1. The upper drainage pipe 1 is embedded in the reinforced concrete bottom slab of the upper modular box, and the lower drainage pipe 1 is embedded in the reinforced concrete top slab of the lower modular box.

[0023] The corrugated hose 2 has flange rings 34 at both ends. The bottom end of the corrugated hose 2 is sealed to the top end of the drain pipe 1 of this floor through the flange rings 34, and a sealing ring is provided at the connection.

[0024] Quick-connect structure 3 is a flange-clamping connection structure, including: A circular ring 33 is located at the bottom end of the upper drainage pipe 1, and the surface of the circular ring 33 is provided with multiple guide plates 35 and columns 36. The guide plate 35 is an arc-shaped plate, and multiple guide plates 35 are arranged in a ring. The distance between two relative guide plates 35 is the same as the outer diameter of the flange ring 34, which is used to guide the flange ring 34 to be coaxially aligned with the ring 33. There are multiple columns 36, and all of them are set on the ring 33 and correspond to the flange holes on the surface of the flange ring 34. The number and position of the columns 36 correspond one-to-one with the number and position of the flange holes on the flange ring 34, so as to ensure that when the flange ring 34 is close to the ring 33, the multiple columns 36 pass through the corresponding flange holes on the flange ring 34. It should be noted that the length of the column 36 is greater than the depth of the flange hole on the flange ring 34; There are a number of adjusting screws 37, which are symmetrically rotated on the ring 33. The other end of the adjusting screw 37 is provided with a rotating handle, which is provided with an internal hexagonal operating part, so that the adjusting screw 37 can be rotated manually or with the help of a tool. Mounting frame 38 has two threaded holes and is screwed to the surface of two adjusting screws 37. The rotation of the two adjusting screws 37 drives the mounting frame 38 to move along the setting direction of the adjusting screws 37. At the same time, the surface of the mounting frame 38 also has two mounting grooves. Two pressure plates 39 are symmetrically mounted in the mounting slots of the mounting frame 38 via pins. The mounting slots limit the rotation range of the pressure plates 39. The pressure plate 39 includes a frame and a pressure plate body set on the frame. The pressure plate body is a fan-shaped plate, and the surface of the pressure plate body has through holes corresponding to the column 36. When two pressure plate bodies are fitted together, they can form a circular structure, which fits perfectly onto the surface of the end of the corrugated hose 2. At the same time, the through holes allow the pressure plate body to fit onto the surface of the column 36. At this time, the pressure plate body and the ring 33 clamp the flange ring 34, and the column 36 achieves axial positioning of the flange ring 34.

[0025] There are two sleeves 4, which are respectively installed on the upper layer and the current layer, and are respectively sleeved on the surface of the drain pipe 1 and the corrugated hose 2.

[0026] The installation method in this embodiment is as follows: 1. Factory prefabrication: When prefabricating the upper modular box, weld a ring 33 onto the upper drainage pipe 1, and then embed it together with the sleeve 4 in the designed position of the bottom plate. Weld the guide plate 35 and the positioning column 36 onto the ring 33, and rotate and install two adjusting screws 37. When prefabricating the modular box of this layer, embed the drainage pipe 1 of this layer together with the sleeve 4 in the designed position of the top plate, and seal the bottom end of the corrugated hose 2 to the drainage pipe 1 of this layer.

[0027] 2. On-site hoisting: After the modular box is hoisted into place, rotate the adjusting screw 37 to move the mounting frame 38, so that the pressure plate 39 is away from the column 36, allowing it to rotate and rotate to be perpendicular to the mounting frame 38. At this time, under the guidance of the guide plate 35, the flange ring 34 automatically aligns with the ring 33 on the same axis, and the flange ring 34 is inserted into the surface of the column 36 until it contacts the annular sealing ring.

[0028] 3. Pressing and sealing: Then, rotate the pressure plate 39 to make it flush with the mounting frame 38, and then rotate the adjusting screw 37 to move the mounting frame 38 closer to the ring 33. At this time, the through hole on the surface of the pressure plate 39 fits into the surface of the column 36. Continue to move the mounting frame 38 until the pressure plate 39 presses the flange ring 34 and causes the annular sealing gasket to be compressed and deformed, thus achieving a seal. When the adjusting screw 37 is rotated to a certain torque, stop rotating to complete the pipeline connection.
