Description

Technical Field

[0001] The utility model relates to the technical field of construction tools, in particular to a water stop belt pressing device. Background Art

[0002] In construction projects, especially underground structures, hydraulic structures and tunnel projects, waterstop is one of the key materials to prevent water penetration. Its function is to seal the joints of the structure and ensure the waterproof performance of the structure. Back-stick waterstop is widely used because of its easy construction and high bonding strength. It is usually directly attached to the concrete surface through the self-adhesive layer on the back to form a continuous waterproof barrier.

[0003] However, in the actual construction process, back-sticked waterstops often face two major technical challenges: one is the debonding problem caused by the poor adhesion between the waterstop and the waterproof board during or after construction, which may be caused by factors such as insufficient cleanliness of the concrete surface, excessive humidity, or uneven pressure during pasting; the other is the tearing or peeling of the waterstop due to structural deformation, changes in groundwater pressure, etc. during use, which in turn affects the waterproof effect of the entire project.

[0022] Combine the following Figure 1 The specific implementation of the water stop belt pressing device of the utility model is described.

[0023] The utility model provides a waterstop pressing device, comprising: a first rod body 10, one end of which is provided with a pressure plate assembly for pressing on the surface of the waterstop; a second rod body 20, which is arranged parallel to the first rod body 10, and an adjustment assembly is arranged between the first rod body 10 and the second rod body 20, so as to adjust the relative positions of the first rod body 10 and the second rod body 20 on the axial defense line; a limiting assembly is arranged on the second rod body 20, and the limiting assembly has a notch 21 in the radial direction toward the second rod body 20. The limiting assembly notch 21 on the second rod body 20 is tightly clamped on a stable structure such as a steel bar or a column adjacent to the waterstop, so as to achieve accurate positioning of itself. At the same time, the pressure plate assembly equipped on the first rod body 10 of the device directly acts on the waterstop, exerts necessary pressure, and ensures a high degree of close fit between the waterstop and the waterproof board. The device allows the user to flexibly adjust the axial relative position of the first rod body 10 and the second rod body 20 through the adjustment component to meet the needs of different working conditions, ensuring that the back waterstop can be tightly combined with the initial support surface under various conditions, avoiding the problem of waterstop falling off, and significantly improving the waterproof reliability and construction quality of construction projects and similar fields.

[0024] Specifically, one end of the first rod body 10 is equipped with a pressure plate assembly, so that the device can directly act on the surface of the water stop, apply uniform and sufficient pressure, and ensure that the water stop and the concrete surface or waterproof board form a tight fit without gaps, thereby greatly reducing the risk of debonding caused by loose adhesion. The second rod body 20 is arranged in parallel with the first rod body 10, and the adjustment assembly between the two allows the distance between the two rod bodies to be adjusted according to actual needs. Regardless of how the specific conditions of the construction site change (such as water stops of different widths or uneven construction surfaces), the device can flexibly adapt to ensure the accurate application of top pressure force, thereby improving the flexibility and efficiency of construction. The limit assembly is located on the second rod body 20, and has a notch 21 with a specific orientation, so that the existing fixed structures on site (such as steel bars or columns) can be used. By clamping the notch 21 on these structures, the position of the entire top pressure device can be stabilized, the positioning and support of the water stop can be enhanced, and displacement during operation can be prevented, ensuring the accuracy and safety of construction.

[0025] Through the above-mentioned structural design, the waterstop pressing device realizes efficient and stable pressing and fixing of the back-sticking waterstop, significantly improving the bonding quality and waterproofing effect, thereby ensuring the long-term waterproofing performance and structural safety of construction projects, especially underground, hydraulic and tunnel projects.

[0026] According to a water stop belt pressing device provided by the utility model, the first rod body 10 is a threaded rod; the adjustment assembly includes a first nut 11 matched with the first rod body 10, and a connecting piece 12 connected between the first nut 11 and the second rod body 20. Through the threaded cooperation between the first nut 11 and the first rod body 10, the position of the adjustment assembly on the first rod body 10 can be moved, thereby changing the axial relative position of the second rod body 20 and the first rod body 10, and realizing fine adjustment of the pressing force and position of the pressure plate assembly.

[0027] According to a water stop pressing device provided by the utility model, the connecting member 12 is fixed to the end of the second rod body 20 shown; or, the end of the connecting member 12 away from the first nut 11 is movably installed on the second rod body 20 along the axial direction of the second rod body 20. Among them, in the embodiment in which the connecting member 12 is fixed to the end of the second rod body 20 shown, by fixing (such as welding) the connecting member 12 to one end of the second rod body 20, it can ensure that the overall structure of the device is more stable, and avoid affecting the accuracy of the pressing due to accidental movement during use, which is suitable for a construction environment with a high degree of standardization. In another embodiment, the end of the connecting member 12 away from the first nut 11 is movably installed on the second rod body 20 along the axial direction of the second rod body 20. While adjusting the first nut 11 to change the axial relative position between the two rod bodies, the connecting member 12 itself can also slide on the second rod body 20, thereby achieving more free positioning, further improving the flexibility and scope of application of the device.

[0028] According to a water stop pressing device provided by the utility model, the connecting member 12 is preferably a connecting rod perpendicular to the axial direction of the second rod body 20. When the first nut 11 rotates relative to the first rod body 10, the connecting member 12 also rotates accordingly, so that the second rod body 20 can rotate around the axis of the first rod body 10 to adjust its orientation.

[0029] According to a waterstop pressing device provided by the utility model, the pressure plate assembly includes a plate body 13 and a second nut 14 fixed to the plate body 13; the second nut 14 is detachably matched with the end of the first rod body 10. The plate body 13 directly acts on the waterstop, and applies pressure through physical contact to ensure that the waterstop fits tightly with the waterproof board or other structural surfaces. The second nut 14 realizes the detachable installation mode of the pressure plate assembly on the first rod body 10, allowing workers to disassemble and replace the pressure plate assembly of suitable size and shape at any time according to needs.

[0030] According to a waterstop pressing device provided by the utility model, an elastic cushion layer is provided on the side of the plate body 13 facing away from the first rod body 10. As a buffer layer, the elastic cushion layer can reduce the direct impact and wear on the waterstop while applying pressure, protect the waterstop material from damage, and extend its service life. In the waterstop pressing device, the selection of the elastic cushion layer needs to meet the requirements of having good elasticity to absorb pressure, providing stable sealing, being friendly and harmless to the waterstop and the contact surface, and having certain weather resistance and durability. Preferably, the elastic cushion layer can be selected from a rubber cushion layer, a thermoplastic elastomer cushion layer, a composite material cushion layer, and the like.

[0031] According to a water stop pressing device provided by the utility model, the above-mentioned limiting assembly preferably includes a first limiting member 22 and a second limiting member 23 which are spaced apart and arranged on the second rod body 20; the first limiting member 22, the second limiting member 23 and the second rod body 20 therebetween jointly form a notch 21. When the device is installed, the notch 21 can be inserted into or sleeved on a steel bar, a column edge or other supporting member, thereby ensuring the stability and positioning accuracy of the pressing device during the entire construction period.

[0032] In one embodiment, the second rod body 20, the first stopper 22, and the second stopper 23 are all steel bars; the first stopper 22 and the second stopper 23 are welded to the second rod body 20. The second rod body 20, the first stopper 22, and the second stopper 23 are formed by welding steel bars, thereby ensuring the reliability and strength of the structure.

[0033] In another embodiment, at least one of the first stopper 22 and the second stopper 23 is movably mounted on the second rod body 20 along the axial direction of the second rod body 20, so that the position of the stopper can be adjusted to adapt to different fixing points or optimize the pressure position according to actual construction requirements, thereby improving the versatility and scope of application of the device. The movable stopper can be adjusted axially by bolts, slide rails or other mechanical connection methods, which is convenient for rapid on-site adjustment, ensuring that the top pressure device can be accurately connected to each specific construction detail, improving construction efficiency and waterproofing effect.

[0034] Preferably, according to a waterstop pressing device provided by the utility model, the second rod body 20 is a threaded rod; the first limiter 22 includes a third nut 24 matched with the second rod body 20 and a first limiter rod 25 fixed to the third nut 24; the second limiter 23 includes a fourth nut 26 matched with the second rod body 20 and a second limiter rod 27 fixed to the fourth nut 26; the first limiter rod 25 and the second limiter rod 27 are respectively perpendicular to the second rod body 20. The threaded fit facilitates the axial position adjustment of the first limiter 22 and the second limiter 23. By rotating the corresponding nut, the position of the limiter rod in the axial direction of the second rod body 20 is adjusted, so as to accurately match the specific needs of the construction site and improve the adaptability and accuracy of the limit.
