Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a rubber waterstop reinforcement system and a method for reinforcing construction joints. Background Technology

[0002] Rubber waterstop reinforcement technology is a specialized technique used in the construction of existing building structures (such as basements, tunnels, pools, bridges, and other concrete structures requiring waterproofing) to compensate for the installation defects of the original waterstop, enhance the reliability of joint waterproofing, or repair leakage problems. The core of this technology is to optimize the fixing method, strengthen the seal, and enhance the integration with the structure to ensure that the rubber waterstop plays the role of a "water-stopping barrier" and blocks the seepage path of water along structural joints (such as construction joints, expansion joints, settlement joints, etc.).

[0003] Traditional methods for installing and reinforcing rubber waterstops often rely on binding positioning steel bars on both sides of the joint and using specialized plastic or metal clips to hold the waterstop to the steel bars. However, this method has revealed several problems in practical applications: First, the clips are poorly compatible with waterstops of different specifications and complex steel reinforcement environments, making them prone to insecure installation; second, the entire reinforcement process is highly dependent on the experience and responsibility of the construction personnel, lacking standardized procedures, which can easily lead to problems such as inaccurate positioning of the waterstop and deviations in flatness and verticality; finally, during concrete pouring and vibration, the waterstop is easily impacted, causing it to float, shift, or twist, and the dense surrounding steel reinforcement makes it difficult to compact the concrete, creating a potential leakage hazard.

[0004] Therefore, there is an urgent need for a reinforcement system and standardized construction method that can accurately position and firmly clamp rubber waterstops, and is easy to construct and has controllable quality.

[0005] The statements herein provide only background information in relation to the present invention and do not necessarily constitute prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a rubber waterstop reinforcement system and a method for reinforcing construction joints, which can solve the problems of inaccurate positioning, easy displacement, and reliance on manual experience in construction of existing rubber waterstops.

[0007] To achieve the above objectives, the present invention provides a rubber waterstop reinforcement system for compensating for installation defects of rubber waterstops and reinforcing construction joints. The rubber waterstop includes an O-ring and a first side plate and a second side plate integrally formed on both sides of the O-ring. During installation, the reinforcement system integrates with pre-embedded limiting units in the original building structure. The rubber waterstop is perpendicular to the original construction joint, and the O-ring is positioned centrally within the construction joint. The reinforcement system includes: The waterstop clamping unit is located on one side of the pre-embedded limiting unit. The waterstop clamping unit includes a first protruding end waterstop locator and a second protruding end waterstop locator arranged vertically upwards and downwards. The first protruding end waterstop locator is located directly above the O-ring, and the second protruding end waterstop locator is located directly below the O-ring, so as to install, position, and clamp the rubber waterstop. The waterstop clamping unit is spaced apart from the pre-embedded limiting unit. The first protruding end waterstop locator has a first cut at its bottom, and both first cut surfaces of the first cut are tangent to the upper circular surface of the O-ring; the second protruding end waterstop locator has a second cut at its top, and both second cut surfaces of the second cut are tangent to the lower circular surface of the O-ring. The positioning frame unit is located on the side of the waterstop clamping unit away from the pre-embedded limiting unit, and includes: a U-shaped frame structure and a two-point support structure. The U-shaped frame structure is located on the side of the first extended end waterstop locator away from the pre-embedded limiting unit. The opening of the U-shaped frame structure is connected to the first extended end waterstop locator, which increases the self-weight of the first extended end waterstop locator, thereby pressing the O-ring and the second side plate in the vertical direction. The two-point support structure is located on the side of the second protruding end waterstop locator away from the pre-embedded limiting unit. The two-point support structure is symmetrically distributed with respect to the central axis of the second protruding end waterstop locator to provide a structure that can withstand oblique loads, thereby tightening the O-ring so that it does not shift. An external active reinforcement unit is disposed on the side of the positioning frame unit away from the waterstop clamping unit, so as to tighten the positioning frame unit from the outside.

[0008] Optionally, the external active reinforcement unit includes: anchoring steel bars and at least three diagonal braces; the anchoring steel bars are anchored on the side away from the positioning frame unit; the diagonal braces include a first diagonal brace, a second diagonal brace, and a third diagonal brace; One end of the first diagonal brace is pressed against the side opposite to the opening in the U-shaped frame structure, and the other end is fixedly connected to the anchoring steel bar; one end of the second diagonal brace and the third diagonal brace are respectively pressed against the two-point support structure, and the other end of the two diagonal braces is fixedly connected to the anchoring steel bar.

[0009] Optionally, the U-shaped frame structure includes: two first fixed square timbers and a third fixed square timber; the first fixed square timbers are horizontally arranged at the top and bottom of the side of the first extended end waterstop locator away from the pre-embedded limiting unit; the third fixed square timber is vertically arranged, and the bottom edge and top edge of the third fixed square timber are respectively connected to the bottom first fixed square timber and the top first fixed square timber. The two-point support structure includes: two L-shaped second fixed square timbers, symmetrically arranged around the central axis of the second protruding end waterstop locator, and located on the side away from the pre-embedded limiting unit; In this configuration, one end of the first diagonal brace is pressed against the midpoint of the third fixed square timber, and the other end is fixedly connected to the anchoring steel bar; one end of the second and third diagonal braces are respectively pressed against the L-shaped intersection of the two second fixed square timbers, and the other ends of the two diagonal braces are fixedly connected to the anchoring steel bar.

[0010] Optionally, the pre-embedded limiting unit includes: multiple upper reinforcing bars, multiple lower reinforcing bars, and multiple reinforcing bar clips; The upper reinforcing bars are located above the lower reinforcing bars; the reinforcing bar clips are used to tie multiple upper reinforcing bars and multiple lower reinforcing bars respectively, and after tying the upper and lower reinforcing bars, a limiting structure is formed between the two sets of reinforcing bars for inserting and clamping the first side plate of the rubber waterstop.

[0011] Optionally, the first side plate faces the pre-embedded limiting unit and is inserted into the limiting structure disposed between the upper and lower reinforcing bars; The second side plate is inserted between the U-shaped frame structure and the two-point support structure.

[0012] Optionally, the positioning frame unit also includes multiple auxiliary fixing timbers, which are equally spaced and parallel between two first fixing timbers and / or two second fixing timbers, providing a more stable support structure for the positioning frame unit. The auxiliary fixing timber set between the two first fixing timbers has one end connected to the first protruding end waterstop positioning device and the other end connected to the third fixing timber. The auxiliary fixing timber, which is set between the two second fixing timbers, has one end connected to the second protruding end waterstop positioner.

[0013] This invention also provides a method for reinforcing construction joints, comprising the following steps: S1. Reinforcing bar binding and pre-embedding: In the original main structure of the building, reinforcing bar clips are used to bind the lower and upper reinforcing bars separately to prevent the upper and lower reinforcing bars from shifting; S2. Determine the installation position of the waterstop clamping unit and install the rubber waterstop; S3. Install the positioning frame unit on the side of the waterstop clamping unit away from the pre-embedded limiting unit; S4. External reinforcement is applied to the positioning frame unit and the waterstop clamping unit using an external active reinforcement unit; S5, concrete is poured in the area containing the pre-embedded limiting unit and the first side plate of the rubber waterstop, and then the positioning frame unit, the waterstop clamping unit and the external active reinforcement unit are removed. Then, concrete is poured in the other side of the rubber waterstop, that is, the area containing the second side plate. After the first side plate and the second side plate of the rubber waterstop are both poured with concrete, a construction joint is formed at the original position of the first protruding end waterstop locator and the second protruding end waterstop locator, and waterproof and buffer materials are filled in the construction joint.

[0014] Optionally, step S2 includes the following steps: S2.1 Determine the installation height of the top of the second protruding end waterstop locator according to the design height, and determine the installation point at a distance of 2cm-3cm from the outside of the steel bar clip, and then install the second protruding end waterstop locator there; S2.2, Install the rubber waterstop, that is, align the O-ring in the center of the waterstop with the top of the second protruding end waterstop locator, and press the lower circular surface of the O-ring tangent to both second cut surfaces, and insert the first side plate between the upper and lower reinforcing bars. S2.3, the first protruding end waterstop locator is fixedly set directly above the O-ring, and the upper circular surface of the O-ring is pressed tightly against both first tangent surfaces, so that the first protruding end waterstop locator, the O-ring, and the second protruding end waterstop locator are on the same vertical line.

[0015] Optionally, step S3 includes the following steps: S3.1, a U-shaped frame structure is installed on the side of the first extended end waterstop locator away from the pre-embedded limiting unit, and the opening of the U-shaped frame structure faces the first extended end waterstop locator; a two-point support structure is installed on the side of the second extended end waterstop locator away from the pre-embedded limiting unit, and it is symmetrically distributed with respect to the central axis of the second extended end waterstop locator. S3.2, Perform verticality calibration, that is, after installing the U-shaped frame structure and the two-point support structure, readjust the installation positions of the second extended end waterstop locator, the O-ring of the rubber waterstop, and the first extended end waterstop locator to ensure that after the fixed positioning frame unit is installed, the three are pressed together and are still on the same vertical line. Verticality calibration is performed by suspending a plumb bob.

[0016] Optionally, step S4 includes: The anchoring steel bars are anchored to the foundation at a predetermined position on the side away from the positioning frame unit; Install diagonal braces so that one end of the first diagonal brace is pressed against the U-shaped frame structure, and the other end is fixedly connected to the anchoring steel bars; make one end of the second and third diagonal braces press against the two-point support structure respectively, and the other end of both diagonal braces is fixedly connected to the anchoring steel bars.

[0017] In summary, compared with the prior art, the present invention has the following beneficial effects: 1. Precise positioning and stable structure: The waterstop is positioned from the inside by pre-embedded limiting units, the positioning frame unit forms a rigid constraint, and the external active reinforcement unit supports from the outside, forming a stable system with internal and external clamping and three-dimensional constraint. It can effectively resist various disturbances during concrete pouring and ensure that the waterstop is accurately positioned, does not shift, and does not deform.

[0018] 2. Standardized construction and controllable quality: The complex reinforcement process is broken down into clear and quantifiable steps (such as measuring height, determining 2-3cm intervals, and using a plumb bob to calibrate verticality), significantly reducing reliance on the individual experience of construction workers. Each step has clear inspection standards, making construction quality easy to control and accept.

[0019] 3. Ensure the quality of concrete construction: The regular square timber frame provides good formwork space for concrete pouring, avoiding the problem of excessive local reinforcement caused by traditional steel bar clips. It is conducive to the filling and vibration of concrete, thereby ensuring the compactness of the concrete around the waterstop and fundamentally reducing leakage channels.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly illustrate the embodiments of the present invention. Please refer to the accompanying drawings to make the objectives, features, and advantages of the present invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of the present invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives achieved by the present invention, should still fall within the scope of the technical content disclosed in the present invention.

[0023] This invention provides a rubber waterstop reinforcement system to compensate for installation defects in the original waterstop and enhance the waterproofing reliability of construction joints or expansion joints. The rubber waterstop includes an O-ring 910 and a first side plate 920 and a second side plate 930 integrally formed on both sides of the O-ring. Figure 1 As shown, the system is an integrated construction tool, mainly composed of a waterstop clamping unit, a positioning frame unit, and an external active reinforcement unit. It is combined with the pre-embedded limiting unit in the original building structure to achieve precise positioning and multi-dimensional stabilization of the rubber waterstop.

[0024] The pre-embedded limiting unit exists within the original building structure and includes multiple upper reinforcing bars 7, multiple lower reinforcing bars 8, and multiple reinforcing bar clips 6. The upper reinforcing bars 7 are located above the lower reinforcing bars 8. The reinforcing bar clips 6 are used to bind the multiple upper reinforcing bars 7 and the multiple lower reinforcing bars 8, and after binding the upper reinforcing bars 7 and the lower reinforcing bars 8, a limiting structure for inserting and clamping the first side plate 920 of the rubber waterstop is formed between the two sets of reinforcing bars. After the reinforcing bar clips 6 are bound, multiple reinforcing bar hooks 610 extend from one side of them. Specifically, after the rebar binding is completed, the rebar hooks 610 of all the rebar clips 6 binding the upper rebar 7 are arranged in sequence to naturally form the first rebar hook group located at the top, and the rebar hooks 610 of all the rebar clips 6 binding the lower rebar 8 are arranged in sequence to naturally form the second rebar hook group located at the bottom. That is, the first rebar hook group is located above the second rebar hook group. The first rebar hook group and the second rebar hook group are conventional building reinforcement structures formed after the rebar clips 6 bind the upper rebar 7 and the lower rebar 8, which are used to form a strong reinforcement structure after the subsequent concrete pouring.

[0025] The waterstop clamping unit is closely related to the positioning frame unit.

[0026] The waterstop clamping unit is located on the side of the pre-embedded limiting unit where the reinforcing bar hook 610 does not extend. The waterstop clamping unit includes a first extended end waterstop locator 110 and a second extended end waterstop locator 120 arranged vertically upwards and downwards. Specifically, the first extended end waterstop locator 110 is positioned directly above the O-ring 910 of the rubber waterstop, and the second extended end waterstop locator 120 is positioned directly below the O-ring 910. Both are used to directly clamp the O-ring 910 of the rubber waterstop during installation. The rubber waterstop is perpendicular to the original construction joint, and the O-ring 910 is positioned in the center of the original construction joint. Furthermore, after the first extended end waterstop locator 110 and the second extended end waterstop locator 120 are installed, the installation positions of the first extended end waterstop locator 110, the O-ring 910, and the second extended end waterstop locator 120 can be considered to partially cover the original construction joint. In one specific embodiment, the width of the original construction joint is wider than the lateral width of the first extended end waterstop locator 110, the O-ring 910, and the second extended end waterstop locator 120.

[0027] Furthermore, such as Figure 2 As shown, the bottom of the first extended end waterstop locator 110 has a first slit, and both first cut surfaces 111 of the first slit are tangent to the upper circular surface of the O-ring 910; the top of the second extended end waterstop locator 120 has a second slit, and both second cut surfaces 121 of the second slit are tangent to the lower circular surface of the O-ring 910, so as to press and fix the O-ring 910 from each radial direction. In addition, an O-ring fixing block 130 is provided at the contact point where the first cut surface 111 is tangent to the upper circular surface of the O-ring 910 to prevent slippage. Similarly, an O-ring fixing block 130 is also provided at the contact point where the second cut surface 121 is tangent to the lower circular surface of the O-ring 910.

[0028] The positioning frame unit, as the rigid skeleton of the system, functions to compress and support the rubber waterstop, effectively preventing the O-ring 910 of the rubber waterstop from shifting. The positioning frame unit includes a U-shaped frame structure located on the side of the first extended end waterstop locator 110 away from the pre-embedded limiting unit. The opening of this U-shaped frame structure connects to the first extended end waterstop locator 110 to form a closed frame structure, thereby increasing the self-weight of the first extended end waterstop locator 110 to compress the O-ring 910 and the second side plate 930 in the vertical direction. The positioning frame unit also includes a two-point support structure located on the side of the second extended end waterstop locator 120 away from the pre-embedded limiting unit. This two-point support structure is symmetrically distributed around the central axis of the second extended end waterstop locator 120 to provide a structure that can withstand oblique loads, thereby pressing the O-ring 910 to prevent displacement. Furthermore, since the second extended end waterstop locator 120 needs to bear additional load-bearing function compared to the first extended end waterstop locator 110, a two-point support structure is set on the side of the second extended end waterstop locator 120 away from the pre-embedded limiting unit and symmetrical to the central axis of the second extended end waterstop locator 120 to provide evenly distributed force support points.

[0029] In a preferred embodiment of the present invention, the positioning frame unit includes two first fixed square timbers 210, two second fixed square timbers 220, both of which are L-shaped, and a third fixed square timber 310. The first fixed timber 210 is horizontally positioned at the top and bottom of the first extended end waterstop locator 110 on the side away from the pre-embedded limiting unit. The third fixed timber 310 is vertically positioned, and its bottom and top edges are respectively connected to the bottom and top of the first fixed timber 210. Through the connection of the first and third fixed timbers 210, a stable U-shaped frame structure is constructed, thereby increasing the self-weight of the first extended end waterstop locator 110 to press the O-ring 910 and the second side plate 930 in the vertical direction. The second fixed timber 220 is symmetrically positioned with respect to the central axis of the second extended end waterstop locator 120 and located on the side of the second extended end waterstop locator 120 away from the pre-embedded limiting unit to form the two-point support structure, providing force support points at both ends of the side of the second extended end waterstop locator 120.

[0030] Furthermore, to enhance the compression and support effects of the U-shaped frame structure and the two-point support structure, auxiliary fixing timbers can be equally spaced and parallelly arranged between the two first fixing timbers 210 and / or between the two second fixing timbers 220. Specifically, one end of the auxiliary fixing timber arranged between the two first fixing timbers 210 is connected to the first protruding end waterstop positioner 110, and the other end is connected to the third fixing timber 310; one end of the auxiliary fixing timber arranged between the two second fixing timbers 220 is connected to the second protruding end waterstop positioner 120.

[0031] During installation, the inner surfaces of the first protruding end waterstop locator 110 and the second protruding end waterstop locator 120 should maintain a certain distance from the outer surface of the reinforcing bar clip 6. The preferred distance is 2-3 cm.

[0032] The external active reinforcement unit is located on the outside of the positioning frame unit (i.e., on the side of the positioning frame unit away from the waterstop clamping unit). Its function is to actively tighten and lock the entire frame from the outside, preventing it from shifting during concrete pouring. This external active reinforcement unit includes one anchoring steel bar 5 and at least three diagonal braces (e.g., a first diagonal brace 410, a second diagonal brace 420, and a third diagonal brace 430). The anchoring steel bar 5 is anchored in the foundation on the side away from the positioning frame unit. One end of the first diagonal brace 410 is tightened against the side of the U-shaped frame structure opposite to the opening, and its other end is fixedly connected to the anchoring steel bar 5. One end of the second diagonal brace 420 and the third diagonal brace 430 are respectively tightened against a two-point support structure, and the other ends of both diagonal braces are fixedly connected to the anchoring steel bar 5. This diagonal brace layout forms a stable triangular support system on the outside of the frame.

[0033] In a preferred embodiment of the present invention, one end of the first diagonal brace 410 is pressed against the midpoint of the third fixed square timber 310, and the other end is fixedly connected to the anchoring steel bar 5; one end of the second diagonal brace 420 is pressed against the L-shaped intersection of the uppermost second fixed square timber 220, and the other end is fixedly connected to the anchoring steel bar 5; one end of the third diagonal brace 430 is pressed against the L-shaped intersection of the lowermost second fixed square timber 220, and the other end is fixedly connected to the anchoring steel bar 5.

[0034] In some embodiments, the diagonal brace further includes a fourth diagonal brace, one end of which abuts against the end of the auxiliary fixed square timber disposed between the two second fixed square timbers 220 that is not connected to the second protruding end waterstop locator 120, and the other end of which is fixedly connected to the anchoring steel bar 5.

[0035] This system is used to reinforce a rubber waterstop comprising an O-ring 910, a first side plate 920, and a second side plate 930. During construction, the first side plate 920 of the rubber waterstop faces the pre-embedded limiting unit and is inserted into the limiting structure located between the upper reinforcing bar 7 and the lower reinforcing bar 8. The left side region of the O-ring 910 (i.e., the first side plate 920 and the pre-embedded limiting unit) is permanently fixed by concrete pouring. The second side plate 930 of the rubber waterstop is inserted between the U-shaped frame structure and the two-point support structure, and the right side region of the O-ring 910 (i.e., the side opposite to the left side region) is also permanently fixed by concrete pouring.

[0036] It should be noted that before pouring the O-ring 910 on the right side, the waterstop clamping unit, the positioning frame unit, and the external active reinforcement unit need to be removed.

[0037] Furthermore, after the left and right sides of the O-ring 910 are poured, that is, after the first side plate 920 and the second side plate 930 of the rubber waterstop are poured with concrete, a construction gap will naturally form at the original positions of the first protruding end waterstop locator 110 and the second protruding end waterstop locator 120. In order to enhance the reliability of the construction gap, foam material will be filled in this area.

[0038] The present invention also provides a method for reinforcing construction joints using the above-mentioned rubber waterstop reinforcement system, the method comprising the following steps: Step S1: Bind and embed the reinforcing bars.

[0039] In the original main structure of the building, steel bar clips 6 are used to tie the lower steel bar 8 and the upper steel bar 7 respectively to prevent the upper steel bar 7 and the lower steel bar 8 from shifting.

[0040] Step S2: Position and install the waterstop clamping unit and the rubber waterstop.

[0041] Specifically, step S2 includes: S2.1 Determine the installation height of the top of the second protruding end waterstop locator 120 according to the design height, and determine the installation point 2-3 cm outside the steel bar clip 6, and then initially install the second protruding end waterstop locator 120 there.

[0042] S2.2, Install the rubber waterstop, that is, align the O-ring 910 in the center of the waterstop with the top of the second extended end waterstop locator 120, and press the lower circular surface of the O-ring 910 tangent to both second cut surfaces 121, and insert the first side plate 920 between the upper steel bar 7 and the lower steel bar 8. S2.3, the first protruding end waterstop positioner 110 is fixedly set directly above the O-ring 910, and the upper circular surface of the O-ring 910 is pressed tightly with both first cutting surfaces 111, and the first protruding end waterstop positioner 110, the O-ring 910 and the second protruding end waterstop positioner 120 are on the same vertical line.

[0043] Step S3: Install the positioning frame unit.

[0044] Specifically, step S3 includes: S3.1, a U-shaped frame structure is installed on the side of the first extended end waterstop locator 110 away from the pre-embedded limiting unit, and the opening of the U-shaped frame structure faces the first extended end waterstop locator 110; a two-point support structure is installed on the side of the second extended end waterstop locator 120 away from the pre-embedded limiting unit, and it is symmetrically distributed with respect to the central axis of the second extended end waterstop locator 120. S3.2, Perform verticality calibration. After installing the U-shaped frame structure and the two-point support structure, readjust the installation positions of the second extended end waterstop positioner 120, the O-ring 910 of the rubber waterstop, and the first extended end waterstop positioner 110 to ensure that after the fixed positioning frame unit is installed, the first extended end waterstop positioner 110, the O-ring 910, and the second extended end waterstop positioner 120 are pressed together and remain on the same vertical line. Verticality calibration is performed by suspending a plumb bob.

[0045] Step S4: External reinforcement is performed on the positioning frame unit and the waterstop clamping unit by the external active reinforcement unit.

[0046] This step aims to set up the external active reinforcement unit. First, anchor steel bars 5 are driven into the foundation at a predetermined position on the side away from the positioning frame unit. Next, diagonal braces are installed, specifically, one end of the first diagonal brace 410 is pressed against the U-shaped frame structure, and the other end is fixedly connected to the anchor steel bar 5; one end of the second diagonal brace 420 and the third diagonal brace 430 are respectively pressed against the two-point support structure, and the other ends of both diagonal braces are fixedly connected to the anchor steel bars 5. At this point, the reinforcement system is installed, forming a stable state of internal and external clamping.

[0047] After completing all the above steps, concrete is poured into the left side area (i.e., the area containing the pre-embedded limiting unit and the first side plate 920 of the rubber waterstop) of the first protruding end waterstop locator 110 and the second protruding end waterstop locator 120. After the concrete has initially set, the positioning frame unit, waterstop clamping unit, diagonal brace, and anchoring steel bar 5, and other reusable components are removed. Then, concrete is poured into the right side area (i.e., the area containing the second side plate 930) opposite to the left side area. After the concrete has been poured into both the left and right sides of the first protruding end waterstop locator 110 and the second protruding end waterstop locator 120, a construction joint will inevitably form in the middle of these two areas. This joint is filled with materials such as foam to provide structural buffering and improve reliability. At this point, the entire reinforcement and installation process of the rubber waterstop is considered complete.

[0048] In summary, the rubber waterstop reinforcement system and the method for reinforcing construction joints provided by this invention construct a rigid external positioning frame in which the rubber waterstop is "embedded," fundamentally solving the problems of low construction accuracy, easy displacement, and difficult quality control in traditional methods. This achieves high-precision, zero-displacement, and verifiable installation of the rubber waterstop, thereby significantly improving the final waterproofing quality of structural joints (including construction joints and expansion joints).
