Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a positioning clamp for steel edge waterstops used in pipe corridors. Background Technology

[0002] In cast-in-place reinforced concrete structures such as integrated utility tunnels and underground tunnels, expansion joints are crucial for ensuring the structure can adapt to temperature changes and uneven settlement, but they are also weak points in waterproofing. Embedded steel-edged rubber waterstops are the most critical waterproofing component for expansion joints.

[0003] A search revealed Chinese patent CN221001150U, which discloses a steel-edged waterstop clamp, comprising a support member supporting the lower part of the steel-edged waterstop and a limiting mechanism clamping the upper part of the steel-edged waterstop. The support member includes a V-shaped portion for supporting the steel-edged waterstop and two horizontal portions respectively disposed at both ends of the upper part of the V-shaped portion, with one end of the horizontal portion connected to the lower main reinforcement. The limiting mechanism includes a limiting plate that fits against one side of the steel-edged waterstop and an adjusting bolt that abuts against the other side of the steel-edged waterstop. The upper part of the limiting plate is provided with a frame rod connected to the upper main reinforcement, and the frame rod is provided with a support rod, with a nut for the adjusting bolt to pass through. This patent, by setting up the support member and the limiting mechanism, facilitates the separate restriction of the upper and lower parts of the steel-edged waterstop. By setting up the adjusting bolt, it is easy to accommodate steel-edged waterstops of different thicknesses, resulting in good performance and strong practicality.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] Existing patents can only passively support the waterstop and cannot actively apply force to bend it, which can easily lead to air bubbles being trapped and affect the waterproofing effect. In addition, they rely on the position of the steel bars, making it difficult to adjust the height and angle. Furthermore, they are inconvenient to disassemble and assemble and can easily damage the surface of the waterstop, thus having certain limitations. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a positioning clamp for steel-edged waterstops used in pipe racks, which enables precise control of the installation shape of the steel-edged rubber waterstop, ensuring that it can stably form and maintain the "basin shape" required by the design.

[0007] The technical solution to achieve the purpose of this utility model is: a positioning clamp for steel-edged waterstops used in pipe racks, comprising a U-shaped clamping module and a main support rod, wherein the inner side of the U-shaped clamping module is provided with a slot, and a fixing component is also included.

[0008] The fixing component includes a U-shaped clamp that is fixedly installed on one side of the bottom of the U-shaped clamping module.

[0009] Preferably, clamps are fixedly installed on the upper and lower sides of the U-shaped clamping module, each clamp is sleeved on the outside of the main support rod, and the U-shaped clamp is sleeved on the outside of the main support rod by connecting bolts.

[0010] Preferably, the U-shaped clamping module has an adjusting bolt installed on its internal thread, and a removable rubber gasket is inserted into the inner side of the U-shaped clamping module through a slot.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] Firstly, this utility model is a combination structure of upper and lower U-shaped clamps and adjusting bolts, which can actively and forcibly bend and clamp the waterstop strip; and the combination of the main support rod, height adjustment mechanism and arc-shaped clamping module realizes flexible adjustment of the clamp height to adapt to different engineering needs.

[0013] Secondly, this utility model precisely controls the shape and position of the waterstop through mechanical devices, fundamentally avoiding quality problems such as non-standard "basin shape" and positional deviation, and greatly improving the waterproof reliability of the expansion joint; mechanical clamping and rigid support can effectively resist the impact and buoyancy during concrete pouring, eliminating the phenomenon of waterstop displacement; the installation process is quick and easy to operate, which greatly improves construction efficiency and reduces labor costs and labor intensity.

[0014] This invention solves the problems of existing patents, which can only passively support the waterstop and cannot actively apply force to bend it, which easily leads to air bubbles being trapped and affects the waterproofing effect. In addition, it is difficult to adjust the height and angle due to the dependence on the position of the steel bars, and the inconvenience of disassembly and assembly can easily damage the surface of the waterstop.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved positioning clamp for steel-edged waterstops used in pipe racks. The technical solution of this utility model is as follows:

[0024] Example 1

[0025] like Figure 1 As shown, a positioning clamp for steel-edged waterstops used in pipe racks includes a U-shaped clamping module 1 and a main support rod 2. The main support rod 2 is made of rigid metal material and hot-dip galvanized to enhance its corrosion resistance. The U-shaped clamping module 1 has a slot on its inner side and also includes a fixing component.

[0026] The fixing components include a U-shaped clamp 6 fixedly installed on one side of the bottom of the U-shaped clamping module 1, which facilitates the secure fixing of the entire clamping template to the construction site.

[0027] Example 2:

[0028] Based on the positioning clamp for steel-edged waterstops used in pipe racks provided in the first embodiment of this application, the second embodiment of this application proposes another positioning clamp for steel-edged waterstops used in pipe racks. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0029] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figures 2-4 As shown, clamps 5 are fixedly installed on the upper and lower sides of the U-shaped clamping module 1. Each clamp 5 is sleeved on the outside of the main support rod 2. The U-shaped clamp 6 is sleeved on the outside of the main support rod 2 by connecting bolts. Anti-slip teeth are added to the inside of the U-shaped clamp 6 to enhance the biting force between the clamp and the main support rod 2.

[0031] Furthermore, the U-shaped clamping module 1 has an internal threaded adjustment bolt 3, and the inner side of the U-shaped clamping module 1 is connected to a removable rubber pad 4 through a slot. The removable rubber pad 4 is added to the clamping surface to avoid damaging the steel edge of the waterstop. The waterstop can be formed into a basin shape and firmly fixed by adjusting the bolt 3.

[0032] The specific working method is as follows: First, according to the design drawings, after completing the rebar binding, accurately lay out the lines on both sides of the expansion joint, and clamp the bottom fixing device of the U-shaped clamping module 1, i.e., the U-shaped clamp 6, onto the main support rod 2 at the predetermined position; second, fix the two U-shaped clamping modules 1 at the design elevation position, fit the clamp 5 onto the main support rod 2, and place the steel-edged rubber waterstop at the center of the expansion joint, with the steel edges on both sides placed between the upper and lower arc-shaped clamps of the clamps on both sides. The removable rubber pads 4 on the clamping surface can effectively prevent damage to the steel edges of the waterstop; finally, tighten the adjusting bolts 3 between the clamps. During this process, the middle part of the waterstop will be forcibly bent by the bolts, thus forming a standard "basin shape" and being firmly clamped; after checking and confirming that all clamps are tight and the position and shape of the waterstop are correct, concrete can be poured; in addition, if you want to reuse the clamps or remove the clamps, if the site conditions permit, the waterstop can be tied to the rebar after it is fixed, and then the clamps can be removed. The clamps play a role in facilitating positioning and shaping.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
