Description

Technical Field

[0001] The utility model relates to the technical field of flue installation, in particular to a leakage-proof flue installation structure. Background Art

[0002] The flue is a tubular device for exhaust gas and smoke discharge. During the power generation process, coal-fired, gas-fired or oil-fired generator sets in thermal power plants will produce a large amount of flue gas due to the combustion of fuel, which is discharged from the flue. It can also be used to remove kitchen smoke or bathroom exhaust gas.

[0003] With the development of society, people generally choose prefabricated flues for the construction of flues. This type of flue is easy to install and has a short construction period. During the flue construction process, the builder often prefabricates the flue according to the floor height of the building design. After the floor construction is completed, the prefabricated flue is pulled to the construction site and installed from the bottom to the upper floor according to the holes reserved in the floor.

[0004] However, after the installation of the pipe, concrete will be poured in the reserved hole to connect and fix the flue to the floor. Since the lower pipe is fixed and the upper pipe has not yet been fixed, the upper pipe will be offset by the impact of the concrete during the pouring of concrete, causing the upper and lower pipes to be misaligned. Later, during the normal use of the flue, there is a risk of water vapor in the flue overflowing from the joint of the upper and lower pipes, affecting the appearance of the wall and causing a bad living experience for the owner. Summary of the invention

[0012] A further technical solution of the utility model is that a sealing layer is circumferentially arranged on one end of the bottom plate facing the second pipeline.

[0013] The beneficial effect is that the sealing performance between the bottom plate and the second pipeline is improved by setting the sealing layer.

[0015] The beneficial effect is that the arrangement of the connecting block and the mounting groove facilitates the splicing alignment between the first pipe and the second pipe, and facilitates construction personnel to determine whether the centers of the first pipe and the second pipe are aligned, thereby reducing subsequent adjustments and improving construction efficiency.

[0016] A further technical solution of the utility model is that a plurality of plug-in rods are circumferentially arranged on one side of the vertical plate away from the elastic member.

[0017] The beneficial effect is that the connection between the vertical plate and the floor plate is increased by setting the plug-in rod, thereby improving the connection strength between the connecting piece and the floor plate.

DETAILED DESCRIPTION

[0030] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0031] like Figure 1-5 As shown, a leakage-proof flue installation structure includes a floor 1, a mounting hole 2 is opened in the floor 1, and a connecting piece 3 is pre-buried at the mounting hole 2 of the floor 1. When the floor 1 is poured, the mounting hole 2 is reserved according to the size of the connecting piece 3, and the connecting piece 3 is installed at the mounting hole 2 for pouring. As the floor 1 is poured, the connecting piece 3 is fixed; the connecting piece 3 includes a vertical plate 31 and a bottom plate 32, the vertical plate 31 is fitted with the inner wall of the mounting hole 2, and the bottom plate 32 is fixedly connected to the vertical plate 31 at one end facing the ground in the height direction, a connecting hole 5 is opened on the bottom plate 32, and a plurality of elastic members 6 are circumferentially installed on the side of the vertical plate 31 away from the floor 1; a pipe 4 is inserted in the connecting hole 5, and the pipe 4 includes a first pipe 41 and a second pipe 42. In order to improve the construction efficiency, the pipe 4 is usually prefabricated in the factory according to the floor height. In this embodiment, in order to facilitate the description of the installation of the pipe 4, the pipe 4 is divided into a first pipe 41 and a second pipe 42. The first pipe 41 is installed in the second pipe 42. 2, the outer wall of the second pipe 42 abuts against the inner wall of the connecting hole 5 as the installation reference of the first pipe 41. In this embodiment, the elastic member 6 is a spring, one end of the spring in the length direction is fixedly connected to the vertical plate 31, and the end of the spring in the length direction away from the vertical plate 31 extends into the connecting hole 5, and the end of the spring in the length direction away from the vertical plate 31 abuts against the outer wall of the first pipe 41 to fix the first pipe 41. When the first pipe 41 is installed, the first pipe 41 squeezes the spring, and the spring applies elastic force to the first pipe 41 under the squeezing action of the first pipe 41, and the first pipe 41 is fixed by the elastic force of the spring, thereby reducing the probability of shaking of the first pipe 41 in the subsequent installation process, reducing the deviation of the alignment of the first pipe 41 and the second pipe 42 due to the shaking of the first pipe 41 in the subsequent construction process, and then causing leakage at the joint between the first pipe 41 and the second pipe 42, thereby reducing the impact of the leakage on the appearance of the wall and the impact on the owner.

[0032] Reference Figure 2 A plurality of plug-in rods 12 are fixedly installed on one side of the vertical plate 31 facing the mounting hole 2. The plug-in rods 12 are fixed in the floor slab 1 during the pouring process of the floor slab 1 to strengthen the connection between the connecting piece 3 and the floor slab 1. Since the pipe 4 itself has a certain weight, when installing the flue in a multi-story building, the bottom pipe 4 needs to bear a large load. In order to disperse the load on the bottom flue, a diagonal brace 13 is installed between the bottom plate 32 and the second pipe 42. Figure 1 The two ends of the diagonal brace 13 in the length direction are fixedly connected to the bottom plate 32 and the second pipe 42 respectively. The existence of the diagonal brace 13 disperses the weight of the pipe 4 to each layer, which is convenient for the subsequent maintenance and replacement of the pipe 4 on a certain layer, and reduces the impact of replacing the pipe 4 on a certain layer on the overall flue.

[0033] Reference Figure 2 , Figure 3 and Figure 4 The end of the elastic member 6 facing away from the vertical plate 31 is fixedly connected with an abutment block 7, and the end of the abutment block 7 facing away from the elastic member 6 is provided with a wedge-shaped surface 8, and the wedge-shaped surface 8 is arranged toward the vertical plate 31. The wedge-shaped block changes the direct contact between the elastic member 6 and the first pipe 41 into indirect contact, while increasing the contact area between the elastic member 6 and the first pipe 41. At the same time, the damage to the surface of the first pipe 41 caused by the direct abutment between the elastic member 6 and the first pipe 41 is reduced. The setting of the wedge-shaped surface 8 facilitates the installation of the first pipe 41; when the first pipe 41 is installed toward the second pipe 42, the outer wall of the first pipe 41 squeezes the wedge-shaped surface 8, and the wedge-shaped surface 8 drives the elastic member 6 to be compressed toward the vertical plate 31 under the squeezing action of the first pipe 41, and the wedge-shaped surface 8 transfers the squeezing of the first pipe 41 to the elastic member 6, and the elastic member 6 compresses and fixes the first pipe 41.

[0034] Reference Figure 2 and Figure 5 A sealing layer 9 is fixedly installed circumferentially on the side of the bottom plate 32 facing the second pipe 42. The sealing layer 9 is made of rubber material. The rubber material is resistant to aging, acid and alkali, cold and heat, so the rubber pad can be used in a variety of environments and provide a reliable sealing effect. When the second pipe 42 is installed, the second pipe 42 squeezes the sealing layer 9, and the sealing layer 9 is squeezed and deformed to seal the gap between the second pipe 42 and the bottom plate 32, thereby improving the sealing between the second pipe 42 and the connecting hole 5.

[0035] Reference Figure 1 and Figure 2 A connecting block 10 and a mounting groove 11 are respectively fixedly installed at both ends of the length direction of the first pipe 41 and the second pipe 42. The size of the connecting block 10 matches that of the mounting groove 11. At the joint between the first flue and the second pipe 42, the connecting block 10 is inserted in the mounting groove 11 to provide a limit for the splicing between the first pipe 41 and the second pipe 42 to reduce the alignment error of the first pipe 41 and the second pipe 42; the mounting block and the mounting groove 11 are respectively installed on the inner walls at both ends of the length direction of the first pipe 41 and the second pipe 42, so that during the installation process, the mounting groove 11 and the connecting block 10 do not contact the wedge block and the sealing layer 9, thereby improving the convenience of the installation process.

[0036] Reference Figure 1 and Figure 2Due to the arrangement of the bottom plate 32, after the first pipe 41 and the second pipe 42 are installed, the vertical plate 31, the bottom plate 32, the first pipe 41 and the second pipe 42 form a gap with a certain shape, and the gap is filled with a connecting layer 14, and the connecting layer 14 fills the gap between the vertical plate 31, the bottom plate 32, the first pipe 41 and the second pipe 42. The connecting layer 14 is made of gypsum, which has the characteristics of good water absorption, high temperature resistance, and flame retardancy. At the same time, gypsum has a certain bonding effect, and then the first pipe 41, the second pipe 42, the vertical plate 31 and the bottom plate 32 are connected, so that there is a strong connection relationship between the vertical plate 31, the bottom plate 32, the first pipe 41 and the second pipe 42; a protective layer 15 is laid on the end of the connecting layer 14 away from the bottom plate 32, and the protective layer 15 is laid on the floor 1 to cover the connecting hole 5. The protective layer 15 uses a foaming material to form a boss with a certain height, which reduces the probability of external substances entering the installation hole 2 and reduces the influence of external substances on the installation of the pipe 4. A waterproof layer is disposed on the surface of the connection layer 14 , and the waterproof layer covers the connection layer 14 .

[0037] In the present invention, the connecting piece 3 is cast together with the floor 1 when the floor 1 is cast. When the flue is constructed, check whether the connection between the connecting piece 3 and the floor 1 is tight, check whether the sealing layer 9 completely covers the inner wall of the connecting hole 5 and whether the connection between the sealing layer 9 and the inner wall of the connecting hole 5 is tight, check whether the mounting groove 11 and the connecting block 10 on the flue are damaged, and whether the elastic member 6 is normally expanded and contracted. After confirming that there are no problems above, the flue is laid. Since the flue is laid layer by layer from bottom to top, it is not necessary to consider the installation of the second pipe 42 when it is located at the bottom layer. Under the action of the external installation equipment, the first pipe 41 is moved toward the mounting hole 2, and the outer wall of the first pipe 41 abuts the wedge surface 8 and squeezes the abutting block 7 so that the abutting block 7 slides toward the vertical plate 31. As a certain connection block 10 of the first pipe 41 is inserted into the mounting groove 11, when the connecting block 10 is inserted into place in the installation groove 11, that is, the first pipe 41 cannot continue to move toward the installation hole 2, the connecting layer 14 is laid to seal the installation hole 2, and then the protective layer 15 is laid on the surface of the floor 1 to complete the installation of the first pipe 41; when installing the middle floor, the diagonal brace 13 is welded between the bottom plate 32 and the second pipe 42 so that the second pipe 42 has strong stability to provide support for the installation of the first pipe 41 and reduce the shaking of the second pipe 42, and the connecting block 10 of the first pipe 41 is inserted into the installation groove 11 by using an external tool, and the first pipe 41 and the second pipe 42 are spliced. The position of the first pipe 41 is fixed under the action of the elastic member 6, and then the connecting layer 14 and the protective layer 15 are laid to complete the sealing of the installation hole 2; repeat the above actions until the installation of the flue is completed.
