Abstract
Description
Technical Field
[0001] This utility model patent relates to the technical field of rubber waterstops, and more specifically, to a fixing structure for rubber waterstops in expansion joints. Background Technology
[0002] Rubber waterstops are commonly used waterproofing materials in construction engineering. They are widely used in expansion joints, construction joints, settlement joints, and other areas. Their waterproofing performance mainly depends on the elasticity and deformation capacity of rubber, which enables them to maintain a seal when the concrete structure deforms.
[0003] In the traditional method of fixing rubber waterstops in expansion joints, the main methods are to rely on steel bars for fixing or to use special clamps for fixing, including using lead wire and templates to strengthen the fixing. Although these methods can fix the waterstops, there are still problems with unreliable fixing in actual applications.
[0004] In existing technologies, such as structures that use wire or formwork for fixing, the waterstop is easily affected by external forces during concrete pouring, which can cause it to shift or deform. For example, the waterstop may be displaced by the buoyancy of the concrete during pouring, or it may be damaged by the wire tying to the reinforcing steel.
[0005] In addition, in traditional fixed structures, the formwork between expansion joints may not be properly sealed, which can lead to problems such as grout leakage and seepage during concrete pouring, thus affecting the installation effect and waterproof performance of the waterstop. Utility Model Content

[0007] This utility model is implemented as follows: a rubber waterstop fixing structure for expansion joints includes an expansion joint formed between casting spaces, with a rubber waterstop provided in the middle of the expansion joint; the rubber waterstop includes an elastic ring, with winged bands extending from both sides of the elastic ring, the elastic ring sealing the middle of the expansion joint, and the winged bands extending into the casting space;
[0008] The casting space is equipped with a steel reinforcement frame, which clamps the wing strip into a sheet-like fixed arrangement; the casting space has a joint end facing the expansion joint, and the joint end is covered by two spaced-apart end templates, with a template gap between the two end templates, and the elastic ring is embedded in the template gap;
[0009] A tongue-and-groove square timber is provided between the two end templates. The two ends of the tongue-and-groove square timber are respectively fixedly connected to the two end templates. The tongue-and-groove square timber abuts against the elastic ring to close the templates at intervals.
[0010] Furthermore, the steel reinforcement frame has strip-shaped clamping grooves, and the wing strips are embedded in the clamping grooves in a sheet-like shape and are clamped and fixed by the steel reinforcement frame.
[0011] Furthermore, the pouring space is provided with multiple longitudinally arranged main reinforcing bars, which are fixedly connected to the reinforcing bar frame at multiple positions to fix the reinforcing bar frame in the pouring space.
[0012] Furthermore, the steel reinforcement frame is arranged in a bent shape, forming multiple bends, and the main steel reinforcement passes longitudinally through the bends and is fixedly connected to the steel reinforcement frame.
[0013] Furthermore, the two end templates abut against the elastic ring, fixing the elastic ring in the template interval.
[0014] Furthermore, the tongue and groove timber has an inner sidewall facing the template spacing, the inner sidewall being arc-shaped, and the inner sidewall abutting against the outer periphery of the elastic ring.
[0015] Furthermore, both ends of the tongue-and-groove square timber extend along the end template to form an extension that abuts against the end template, and the extension is fixedly connected to the end template.
[0016] Furthermore, a fixing nail is inserted through the outer extension, and the fixing nail is inserted into the end template to fix the end template to the tongue and groove square timber.
[0017] Furthermore, the outer sides of the two end templates are provided with fixedly arranged main square timbers, and there is a reinforcing interval between the main square timbers and the end templates. The reinforcing interval is provided with multiple side square timbers and two central square timbers.
[0018] The side square timber is supported between the end template and the main square timber, thereby fixing the end template and the main square timber relatively together; the middle square timber is supported between the tongue and groove square timber and the main square timber, thereby fixing the tongue and groove square timber and the main square timber relatively together.
[0019] Furthermore, a reinforcing steel pipe is provided on the outside of the main square timber, and the reinforcing steel pipe presses against the main square timber to fix the main square timber in place.
[0020] Compared with existing technologies ， The expansion joint rubber waterstop fixing structure provided by this utility model uses a steel frame to clamp the winged strip and embeds the elastic ring into the template interval of the end template, which can effectively prevent the waterstop from shifting during the pouring process and ensure its accurate and stable position in the expansion joint, thereby achieving a reliable fixation of the expansion joint rubber waterstop.
[0021] Next, the tongue-and-groove timber is used to abut the elastic ring and seal the template interval, enhancing the sealing performance of the waterstop. Combined with the synergistic effect of the reinforcing steel frame, end templates, and tongue-and-groove timber, a stable support structure is provided for the rubber waterstop in the expansion joint.

[0029] Reference Figure 1-2 The image shown is a preferred embodiment of the present invention.
[0030] The expansion joint rubber waterstop fixing structure includes an expansion joint formed in the casting space 102, and a rubber waterstop is provided in the middle of the expansion joint; the rubber waterstop includes an elastic ring 100, and winged bands 101 extend from both sides of the elastic ring 100 respectively. The elastic ring 100 is sealed in the middle of the expansion joint, and the winged bands 101 extend into the casting space 102.
[0031] The casting space 102 is provided with a steel reinforcement frame 103, which clamps the wing strip 101 and fixes it in a sheet-like arrangement; the casting space 102 has a joint end facing the expansion joint, and the joint end is covered by two spaced-apart end templates 200, with a template gap 201 between the two end templates 200, and an elastic ring 100 is embedded in the template gap 201.
[0032] A tongue-and-groove square timber 202 is provided between the two end templates 200. The two ends of the tongue-and-groove square timber 202 are respectively fixedly connected to the two end templates 200. The tongue-and-groove square timber 202 abuts against the elastic ring 100 and closes the template interval 201.
[0033] The above-mentioned deformation joint rubber waterstop fixing structure, by clamping the wing belt 101 with the steel frame 103 and embedding the elastic ring 100 into the template interval 201 of the end template 200, can effectively prevent the waterstop from shifting during the pouring process, and ensure its accurate and stable position in the deformation joint, thereby achieving a reliable fixation of the deformation joint rubber waterstop.
[0034] Next, the tongue-and-groove timber 202 abuts against the elastic ring 100 and seals the template interval 201, enhancing the sealing performance of the waterstop. Combined with the synergistic effect of the steel reinforcement frame 103, the end template 200, and the tongue-and-groove timber 202, a stable support structure is provided for the rubber waterstop of the expansion joint. This allows it to better adapt to the deformation requirements of the expansion joint while avoiding the risk of leakage due to tearing or damage to the waterstop.
[0035] In this embodiment, the steel reinforcement frame 103 has strip-shaped clamping grooves 106, and the wing strips 101 are embedded in the clamping grooves 106 in a sheet shape and are clamped and fixed by the steel reinforcement frame 103.
[0036] In this way, the wing strip 101 can be firmly embedded in the clamping groove 106 and fixed by the clamping force of the steel frame 103, effectively preventing the wing strip 101 from shifting or deforming due to external forces during the pouring process, thereby significantly improving the fixing effect of the waterstop.
[0037] In this embodiment, the pouring space 102 is provided with a plurality of longitudinally arranged main steel bars 105, and the plurality of main steel bars 105 are fixedly connected to the steel bar frame 103 at multiple positions, thereby fixing the steel bar frame 103 in the pouring space 102.
[0038] Through the multi-position fixed connection between the main steel bar 105 and the steel bar frame 103, the steel bar frame 103 can obtain stable support in the pouring space 102, ensuring that it will not be displaced or deformed by external forces during the concrete pouring process, thus providing a reliable structural foundation for the fixation of the wing belt 101.
[0039] In this embodiment, the steel reinforcement frame 103 is arranged in a bent shape, forming multiple bending positions 104. The main steel reinforcement 105 passes through the bending positions 104 longitudinally and is fixedly connected to the steel reinforcement frame 103.
[0040] The bent arrangement increases the contact area and connection points between the steel reinforcement frame 103 and the main steel reinforcement 105, enhances the stability of the steel reinforcement frame 103, and enables it to better withstand various external forces during the concrete pouring process, providing a more stable support for the fixation of the wing belt 101.
[0041] In this embodiment, the two end templates 200 abut against the elastic ring 100, fixing the elastic ring 100 in the template interval 201.
[0042] With the end templates 200 abutting against each other, the elastic ring 100 is firmly fixed within the template interval 201. This effectively prevents the elastic ring 100 from shifting during the pouring process, ensuring its precise sealing in the middle of the expansion joint, thereby improving the sealing performance of the waterstop.
[0043] In this embodiment, the tongue and groove square timber 202 has an inner sidewall 203 facing the template interval 201. The inner sidewall 203 is arc-shaped and abuts against the outer periphery of the elastic ring 100.
[0044] By matching the arc-shaped inner sidewall 203 with the outer circumference of the elastic ring 100, the elastic ring 100 can be better fitted, providing uniform abutment force and further enhancing the fixing effect of the elastic ring 100, while avoiding damage to the elastic ring 100 caused by local stress concentration.
[0045] In this embodiment, the two ends of the tongue and groove square timber 202 are respectively extended to the end template 200 to form an extension 204 that abuts against the end template 200, and the extension 204 is fixedly connected to the end template 200.
[0046] This allows the tongue and groove timber 202 to form a stable connection with the end template 200 through the extension 204, enhancing the fixing effect of the tongue and groove timber 202. At the same time, it provides more reliable support for the elastic ring 100, ensuring its stability during the pouring process.
[0047] In this embodiment, the extension portion 204 is provided with a fixing nail 205, which is inserted into the end template 200 to fix the end template 200 to the tongue and groove square timber 202.
[0048] The connection between the end template 200 and the tongue and groove square timber 202 is made more secure by the fixing nails 205, which further enhances the stability of the entire fixed structure and ensures that no relative displacement occurs between the components during the pouring process.
[0049] In this embodiment, main square timber 206 is fixedly arranged on the outer side of the two end templates 200. There is a reinforcement interval 207 between the main square timber 206 and the end templates 200. Multiple side square timbers 208 and two middle square timbers 209 are provided in the reinforcement interval 207.
[0050] The side timber 208 is supported between the end template 200 and the main timber 206, thus fixing the end template 200 and the main timber 206 relatively. The middle timber 209 is supported between the tongue and groove timber 202 and the main timber 206, thus fixing the tongue and groove timber 202 and the main timber 206 relatively.
[0051] Since the central square timber 209 is supported between the tongue and groove square timber 202 and the main square timber 206, it relatively fixes the tongue and groove square timber 202 and the main square timber 206, thus enhancing the stability of the end template 200 and the tongue and groove square timber 202. Through the supporting effect of the side square timber 208 and the central square timber 209, it ensures that each component remains stable during the pouring process, thereby improving the reliability of the entire fixed structure.
[0052] In this embodiment, a reinforcing steel pipe 210 is provided on the outside of the main square timber 206. The reinforcing steel pipe 210 presses against the main square timber 206 to fix the main square timber 206 in place.
[0053] The pressure action ensures that the main timber 206 will not shift or deform during the pouring process, thus providing more reliable support for the entire waterstop structure and further improving the stability and reliability of the waterstop structure.
[0054] In this embodiment, two central square timbers 209 are arranged at intervals, and there is a clamping gap between the two central square timbers 209. The wing band 101 is clamped in the clamping gap, and the central square timbers 209 press against the tongue and groove square timbers 202 towards the elastic ring 100.
[0055] This enhances the fixing effect of the wing strap 101 and improves the overall fixing effect of the waterstop. Furthermore, the pressure of the central square timber 209 against the tongue and groove square timber 202 improves the stability of the overall structure.
[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
