Description

Technical Field

[0001] This utility model relates to the field of cooling water pipe fixing technology, specifically a large-volume concrete cooling water pipe fixing device. Background Technology

[0002] Large-volume concrete generates a lot of heat during the hardening process. If the temperature is not well controlled, cracks are likely to occur, affecting structural safety. In the construction of large-volume concrete bridges, the cooling water pipe system is the core technology for controlling the heat of hydration and preventing temperature cracks.

[0003] Traditional methods for fixing cooling water pipes mainly include: wire binding (fixing the cooling water pipe to the reinforcing steel frame by wrapping it with wire, relying on manual binding and adjustment of position), simple welded support frames (welding short steel bars to the reinforcing steel as temporary support points, with the pipe directly resting on the support frame), and plastic cable ties (using nylon cable ties to bind the pipe to the surface of the reinforcing steel, relying on the tensile strength of the cable ties to maintain position). While these methods can achieve basic fixation, they still have significant technical drawbacks in practical engineering:

[0004] 1. Insufficient friction between the wire binding or nylon cable tie and the contact surface of the reinforcing bar makes the pipes prone to displacement due to impact during concrete pouring and vibration (which can easily cause uncontrolled pipe spacing, resulting in localized cooling blind zones, and internal concrete temperature differences exceeding 25°C, leading to through-cracks).

[0005] 2. The wire binding points are prone to rust and breakage (rust rate ≥ 0.1 mm / year). The welded support frame is prone to deformation and failure under long-term load due to the decrease in strength of the heat-affected zone (which can easily cause the pipe to sink or shift, shorten the service life of the cooling system, and increase the risk of temperature control failure in large-volume concrete). Therefore, it is necessary to improve the fixing device for large-volume concrete cooling water pipes to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a fixing device for large-volume concrete cooling water pipes to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a large-volume concrete cooling water pipe fixing device, comprising an L-shaped fixing block, a rectangular block provided on the inner side of the L-shaped fixing block, two bolts installed on the internal thread of the rectangular block, a rotating shaft rotatably mounted inside the L-shaped fixing block and the rectangular block, a clamping block one fixedly mounted on the right end of the rotating shaft, the number of clamping blocks one being two, and another clamping block one being fixedly mounted on the left side of the L-shaped fixing block.

[0008] Preferably, both bolts are threaded inside the L-shaped fixing block, and the two clamping blocks are distributed on the left and right sides of the L-shaped fixing block.

[0009] Preferably, a second clamping block is provided on the outer side of each of the two clamping blocks one, a friction pad one is fixedly installed inside each of the two clamping blocks one, and two L-shaped inserts are fixedly installed on the side of each of the two clamping blocks two near the clamping block one.

[0010] Preferably, the clamping block one has a slot at the corresponding position of the L-shaped plug, and the L-shaped plug is inserted into the slot and abuts against the outside of the friction pad one.

[0011] Preferably, the clamping block one and the clamping block two are fitted together, and friction pads two are fixedly installed on the inner sides of both the clamping block one and the clamping block two.

[0012] Preferably, a protruding ridge is fixedly installed on the inner side of the second friction pad.

[0013] Compared with the prior art, this utility model provides a fixing device for large-volume concrete cooling water pipes, which has the following beneficial effects:

[0014] 1. This large-volume concrete cooling water pipe fixing device uses an L-shaped insert rod to engage with the internal slot of clamping block one, enabling clamping block one and clamping block two to quickly clamp the reinforcing steel (or cooling pipe), making the installation of the cooling pipe faster.

[0015] 2. Based on this, in this utility model, the rotating shaft rotates inside the L-shaped fixing block and the rectangular block, so that the right clamping block and its connected parts can be installed on the outside of the vertical or diagonal steel bars, making installation and adjustment more convenient and use more flexible.

[0016] 3. Based on this, the present invention uses bolts to install the L-shaped fixing block and the rectangular block to limit the installation of the rotating shaft, so that the left clamping block and its connected parts and the right clamping block and its connected parts can be arbitrarily combined according to the specific diameter of the steel bar and the cooling pipe, making the device more flexible in use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1:

[0026] Please see Figure 1-4 This utility model provides a technical solution: a large-volume concrete cooling water pipe fixing device, including an L-shaped fixing block 1, a rectangular block 2 is provided on the inner side of the L-shaped fixing block 1, two bolts 3 are installed in the internal thread of the rectangular block 2, a rotating shaft 4 is rotatably installed inside the L-shaped fixing block 1 and the rectangular block 2, a clamping block 5 is fixedly installed on the right end of the rotating shaft 4, there are two clamping blocks 5, and another clamping block 5 is fixedly installed on the left side of the L-shaped fixing block 1.

[0027] Furthermore, both bolts 3 are threaded inside the L-shaped fixing block 1, and two clamping blocks 5 are distributed on the left and right sides of the L-shaped fixing block 1, which facilitates the installation of the cooling pipe and the reinforcing bar.

[0028] Furthermore, clamping blocks 6 are provided on the outer sides of both clamping blocks 1 5, friction pads 7 are fixedly installed inside both clamping blocks 1 5, and two L-shaped inserts 8 are fixedly installed on the side of both clamping blocks 2 6 near clamping blocks 1 5, so that clamping blocks 1 5 and clamping blocks 2 6 can be quickly installed and fixed.

[0029] Example 2:

[0030] Please see Figure 3-4 Furthermore, in conjunction with Embodiment 1, it is further found that the clamping block 5 and the L-shaped plug 8 are provided with slots at their corresponding positions, and the L-shaped plug 8 is inserted into the slot. The L-shaped plug 8 abuts against the outside of the friction pad 7. The friction pad 7 has a certain fixed damping, but it will not be too forceful for an adult. The portability it brings is far greater than the inconvenience of pushing and plugging it in for installation.

[0031] Furthermore, clamping block 5 and clamping block 6 are fitted together, and friction pads 9 are fixedly installed on the inner sides of both clamping block 5 and clamping block 6, so that the clamping is tighter while protecting the cooling pipe.

[0032] Furthermore, the inner side of the friction pad 2 9 is fixedly installed with a protruding ridge, so that the clamping block 1 5 and the clamping block 2 6 are fixed in position after being installed on the outside of the cooling pipe or the reinforcing bar, and will not easily shift.

[0033] In actual operation, when this device is used, the right clamping block 5 is attached to the outside of the rebar. The clamping block 6 is moved to offset the clamping block 5, so that the L-shaped insert 8 corresponds to the opening of the slot inside the clamping block 5. Then, the clamping block 6 is pushed backward, so that the L-shaped insert 8 is inserted into the slot until the bottom of the L-shaped insert 8 abuts against the bottom of the slot. At this time, the clamping block 5 and the clamping block 6 are attached, so that the clamping block 5 and the clamping block 26 are locked to the outside of the rebar, thus completing the installation of the device with the rebar. Then, the cooling pipe is attached to the inside of the left clamping block 5. Then, the left clamping block 26 is installed by cooperating with the slot through the L-shaped insert 8 to clamp the cooling pipe, thus completing the fixed-point fixation of the cooling pipe and the rebar. The device is installed at intervals according to the specific situation, thus completing the installation of the cooling pipe and the rebar.

[0034] Furthermore, friction pads 9 are fixed to the inner sides of both clamping block 5 and clamping block 6, and the inner side of friction pads 9 is provided with protruding ridges. This ensures that clamping block 5 and clamping block 6 are fixed in position after being installed on the outside of the cooling pipe (or reinforcing bar), and will not shift during subsequent pouring. The fixed spacing between the two devices ensures that the cooling pipe is installed stably. This avoids the problem of insufficient friction between the conventional wire binding or nylon cable ties and the reinforcing bar, which can cause the pipe to be easily impacted and displaced during concrete pouring and vibration. It also avoids the problem of the cooling pipe falling off and failing to cool due to the easy corrosion and breakage of the wire.

[0035] Furthermore, the rotating shaft 4 rotates inside the L-shaped fixing block 1 and the rectangular block 2, allowing the right clamping block 5 and its connected components to be installed on the outside of the vertical or diagonal steel bars, making installation and adjustment more convenient and use more flexible.

[0036] Furthermore, the L-shaped fixing block 1 and the rectangular block 2 are closed by bolts 3 to limit the installation of the rotating shaft 4, so that the left clamping block 5 and its connected parts and the right clamping block 5 and its connected parts can be freely combined according to the specific diameter of the steel bar and the cooling pipe, making the device more flexible in use.

[0037] Furthermore, a friction pad 7 is fixed inside the slot of the clamping block 5, so that the friction pad 7 will have a certain fixed damping during the compression process of the L-shaped plug 8 being inserted into the slot, but it will not be too forceful for an adult. The portability it brings far outweighs the inconvenience of pushing and plugging in the installation.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
