Description

Technical Field

[0001] The utility model belongs to the technical field of building drainage, and in particular relates to a flexible connection structure of a drainage trough. Background Art

[0002] Siphon drainage troughs are already widely used in the field of construction. A Chinese patent (publication number CN215291028U) discloses a water seepage siphon drainage trough, which is assembled from multiple drainage trough monomers. The number of assembled drainage trough monomers can be selected according to the length requirements, which is convenient for controlling the length. Even if a certain part of the siphon drainage trough is damaged, only the drainage trough monomers at the corresponding part need to be replaced. However, the drainage trough is formed by plugging multiple drainage trough monomers together. Temperature changes cause gaps in the plug-in connection between the drainage trough monomers, which in turn causes air or water leakage, affecting drainage efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a flexible connection structure for a drainage trough in order to solve the above-mentioned technical problems, which can avoid, to a certain extent, the generation of gaps at the plug-in connections between drainage trough units caused by temperature changes, thereby causing air or water leakage and affecting drainage efficiency.

[0004] In view of this, the utility model provides a flexible connection structure of a drainage trough, comprising: a drainage trough monomer, the drainage trough monomer is fixed by a ring-connecting plate, a waterproof sealing ring is sandwiched between the ring-connecting plate and the drainage trough monomer at the connection, and a deformation groove is provided on the sealing ring and the drainage trough abutting side.

[0005] In the present technical solution, the drainage trough is composed of a plurality of drainage trough monomers, and the plurality of drainage trough monomers can be combined and connected according to actual needs and space conditions, providing greater flexibility. When a single drainage trough is damaged or needs to be replaced, the monomer can be handled separately without replacing the entire drainage trough system, which greatly reduces the maintenance cost and complexity. The drainage trough monomers are fixed to each other by a ring-joint plate. While fixing the drainage trough monomer, the ring-joint plate presses and fixes the sealing ring with the deformation groove between the ring-joint plate and the connected drainage trough monomer, and a gap is left between the two connected drainage trough monomers. The above arrangement can avoid excessive deformation and bursting when the drainage trough monomer is deformed due to temperature changes, and can also avoid gaps at the connection, which will lead to air leakage or water leakage, affecting the drainage efficiency.

[0006] In the above technical solution, further, the annular plate includes an arc-shaped main plate, and shoulder plates are provided at both ends of the main plate corresponding to the flanges of the drainage trough monomer, and the two sides of the shoulder plate extend to form a fixed plate, and the fixed plate and the drainage trough monomer are fixed by fasteners, and empty grooves are provided in the shoulder plate and the main plate, and the empty groove and the top surface of the end side of the drainage trough monomer constitute an installation groove for accommodating a waterproof sealing ring.

[0007] In the present technical solution, the fixed plate and the drainage trough monomer extended from both sides of the shoulder plate are threadedly connected by fasteners such as screws and bolts, the fixed plate and the drainage trough monomer are flanged and fitted, and the main plate of the ring plate and the shoulder plate fully press the waterproof sealing ring in the installation groove to ensure the sealing, avoid air leakage or water leakage, and affect the drainage efficiency.

[0008] In the above technical solution, further, the drainage trough unit is provided with ring-joining grooves at both ends corresponding to the ring-joining plates.

[0009] In the present technical solution, ring-joining grooves are symmetrically arranged on both sides of the head and tail of the drainage trough monomer. The arrangement of the ring-joining grooves can quickly help the ring-joining plate to be positioned, thereby facilitating the fixing of the ring-joining plate and improving assembly efficiency.

[0010] In the above technical solution, further, after the ring-joint plate is fixed, the supporting feet on both sides of the empty groove of the ring-joint plate are in the ring-joint groove, and a gap is left between the supporting feet and the inner wall of the ring-joint groove.

[0011] In this technical solution, after the ring-joint plate is fixed, a gap is left between the ring-joint plate supporting foot and the inner wall of the ring-joint groove, that is, the width and depth of the ring-joint groove are larger than the ring-joint plate supporting foot, reserving deformation space for the drainage trough unit. The function of the ring-joint groove is to assist positioning rather than limit fixation.

[0012] In the above technical solution, further, the waterproof sealing ring includes a ring portion and ends on both sides, the ring portion and the drainage board abutting side are provided with deformation grooves, and the ends are used to fill the gaps between adjacent flanges of two drainage trough monomers.

[0013] In this technical solution, the waterproof sealing ring seals the two connected drainage boards. The setting of the deformation groove can not only reduce the material while ensuring the sealing effect, but also reserve the deformation space. When the drainage trough monomer is deformed due to temperature change, the sealing effect can continue to be guaranteed to avoid affecting the drainage efficiency. The end is a "T"-shaped rubber block viewed from the side, which can achieve a good sealing effect between the shoulder plate and the adjacent flanges of the two connected drainage trough monomers.

[0014] In the above technical solution, further, the deformation groove in the waterproof sealing ring is dovetail-shaped.

[0015] In this technical solution, the deformation groove is dovetail-shaped and aligned with the gap between the two drainage groove units. The waterproof sealing ring can cooperate with the drainage groove unit to complete partial deformation, and at the same time can provide a larger contact area when subjected to force, thereby having better load-bearing capacity.

[0016] In the above technical solution, further, staggered reinforcing ribs are provided on the outer side surface of the drainage trough unit.

[0017] In this technical solution, the staggered reinforcement ribs can provide better support, prevent the gutter from deforming when subjected to heavy pressure or external force impact, ensure the stability of the drainage system, help reduce the impact of thermal expansion and contraction caused by temperature changes, avoid cracks or leaks, and extend the service life of the gutter.

[0018] In the above technical solution, further, the reinforcing rib includes a first reinforcing rib and a second reinforcing rib, the first reinforcing rib is fixedly connected to the outer wall of the drainage trough monomer along the circumferential direction of the drainage trough monomer, the second reinforcing rib is fixedly connected to the outer wall of the drainage trough monomer, and the second reinforcing rib and the first reinforcing rib are vertically staggered.

[0019] In the present technical solution, the first reinforcing rib is connected from one side of the flange, fixedly connected to the outer wall of the drainage trough monomer along the circumferential direction of the drainage trough monomer, and extends to the other side of the flange. There are several first reinforcing ribs and second reinforcing ribs, depending on the volume of the drainage trough. The above arrangement provides a more uniform supporting force to prevent the drainage trough from deforming when subjected to uneven pressure or impact, thereby improving the stability of the overall structure.

[0020] 1. The drainage trough monomer is fixed by a ring plate. A waterproof sealing ring is sandwiched between the ring plate and the drainage trough monomer at the connection. A deformation groove is set on the sealing ring and the drainage trough contact side. When the drainage trough monomer is deformed due to temperature changes, it can avoid excessive deformation and bursting, and also avoid gaps at the connection, which will lead to air leakage or water leakage and affect drainage efficiency.

[0021] 2. The staggered arrangement of the first reinforcement ribs and the second reinforcement ribs provides a more uniform support force, preventing the gutter from deforming when subjected to uneven pressure or impact, thereby improving the stability of the overall structure.
