Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering expansion joints, in particular to a waterproof device for civil engineering expansion joints. Background Art

[0002] Concrete structures with larger planes will develop cracks due to thermal expansion and contraction. Therefore, in order to adapt to the expansion and contraction of the structure under temperature changes, an expansion joint device will be installed. Bridge expansion joint devices are usually of the butt-jointed type, steel plate type, combined shear type, modular support type, and seamless type. Among them, the butt-jointed expansion joint device has a simple structure and a wide variety. The butt-jointed expansion joint device generally includes two steel components and a rubber belt connected between the steel components on both sides. The rubber belt can adapt to tensile and compressive deformation and play a waterproof role.

[0003] At present, rubber belts are generally arranged in a "V" shape, in which water and debris are easily accumulated. The presence of water for a long time may affect the service life of the rubber belt. In addition, if debris such as stones fall onto the rubber belt, when the rubber belt is squeezed again, the stones will be squeezed between the rubber belt and may also cause damage to the rubber belt, thereby affecting the waterproof effect of the rubber belt. Summary of the invention

[0004] The utility model provides a waterproof device for civil engineering expansion joints with improved waterproof effect, and aims to solve the problem of protecting a rubber belt and prolonging the service life of the rubber belt.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a waterproof device for expansion joints in civil engineering, comprising steel components on both sides and a rubber belt connected between the steel components on both sides, a cavity is provided inside the steel component, a cover plate connected to the cavity is provided on the top, and a through groove connected to the cavity is provided on one side close to the rubber belt, and the rubber belt is arranged in an inverted "V" shape, with the end corresponding to the through groove.

[0006] Preferably, the through groove is arranged obliquely from the rubber belt toward the cavity.

[0007] Preferably, a plurality of through slots are provided, and plates are provided on opposite sides of the steel members at both sides, and a plurality of rods are slidably connected between the plates at both sides, and the distance between adjacent rods is smaller than the through slot.

[0008] Preferably, a limit baffle is provided at the end of the rod body.

[0009] Preferably, the plate body and the steel member are detachably connected by bolts.

[0010] Preferably, the cover plate and the steel member are detachably connected by bolts.

[0011] Preferably, a plurality of ventilation holes are provided on the cover plate.

[0012] Preferably, a clamping piece for sealing and clamping with the rubber belt is provided on the steel component.

[0013] Preferably, the clamping member is integrally formed with the steel member.

[0014] Compared with the prior art, the rubber belt in the utility model is arranged in an inverted "V" shape, which can transfer water and debris on its surface to the cavity through the through groove. It is not easy for water and debris to accumulate on its surface, which can reduce the blistering time of the rubber belt. When the rubber belt is squeezed, it will not be affected by the debris, which can protect the rubber belt, extend the service life of the rubber belt, and improve the waterproof effect of the rubber belt.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] like Figures 1 to 3 As shown, a waterproof device for expansion joints in civil engineering includes steel components 3 on both sides and a rubber belt 9 connected between the steel components 3 on both sides. A cavity 4 is provided inside the steel component 3, which may be in a "mouth" shaped structure. A cover plate 6 connected to the cavity 4 is provided on the top. A through groove 5 connected to the cavity 4 is provided on one side close to the rubber belt 9. The rubber belt 9 is arranged in an inverted "V" shape, and the end portion corresponds to the through groove 5.

[0024] Working principle: When rainwater, stones, etc. fall on the rubber belt 9, due to the downward inclination of both sides of the rubber belt 9, they will slide along the rubber belt 9 to the through groove 5 and fall into the cavity 4. No debris will accumulate on the rubber belt 9. When the rubber belt 9 is squeezed, it will not be blocked by debris and cause damage. It can greatly protect the rubber belt 9 and improve the waterproof effect. When in use, you only need to check and clean the cavity 4 regularly, which is convenient to use.

[0025] The installation of the device is roughly the same as that of a conventional expansion joint device, and the device can be connected to reinforced concrete through the fixing plate 2 and the fixing ribs 1.

[0026] Preferably, the through groove 5 is inclined from the rubber belt 9 toward the cavity 4 , which is conducive to the debris sliding down the through groove 5 .

[0027] Preferably, there are multiple through grooves 5, that is, the parts between adjacent through grooves 5 can support the upper part of the steel member 3 to ensure the stability of the steel member 3. The steel members 3 on both sides are provided with plates 7 on the opposite sides, and a plurality of rods 8 are slidably connected between the plates 7 on both sides. The distance between adjacent rods 8 is smaller than the through grooves 5. Debris can be filtered through the rods 8, so that the fallen debris can pass through the through grooves smoothly.

[0028] Preferably, a limit baffle 12 is provided at the end of the rod body 8 to limit the distance between the two steel components 3 and prevent excessive stretching and damage to the rubber belt 9.

[0029] Preferably, the plate body 7 is detachably connected to the steel member by bolts, and the plate body 7 can be removed to inspect or replace the rubber belt 9.

[0030] Preferably, the cover plate 6 is detachably connected to the steel member 3 by bolts, so that the cover plate 6 can be opened at regular intervals to clean the interior of the cavity 4 .

[0031] Preferably, a plurality of ventilation holes 10 are provided on the cover plate 6. When water accumulates in the cavity 4, the evaporation of the water can be accelerated by wind flow, and the internal situation of the cavity 4 can be observed through the ventilation holes 10 to determine whether to clean it, which is more convenient to use.

[0032] Preferably, a fastening piece 11 for sealing and fastening with the rubber belt 9 is provided on the steel component 3. Specifically, the fastening piece 11 and the steel component 3 are integrally formed, and have good sealing performance.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
