Description

Technical Field

[0001] This utility model relates to the field of cap beam construction technology, specifically to an automatic spray curing device for cap beams. Background Technology

[0002] Cap beams are common components of viaducts, typically constructed of reinforced concrete. During construction, the concrete requires water curing to prevent cracking.

[0003] In traditional technology, spraying technology for the top surface of the bridge cap is relatively mature and there is a considerable amount of equipment available. However, there is less equipment available for spraying the bottom surface of the bridge cap, and construction workers still mostly stand under the bridge and use high-pressure water guns to spray the water. In hot weather, the water evaporates quickly, and in extreme cases, spraying may be required every 30 minutes. Frequent spraying by construction workers consumes a lot of manpower, thus creating a demand for automated spraying technology. Summary of the Invention

[0048] Reference Figure 1 The cap beam 4 is fixedly installed on the top of the support column 5 by integral casting. The cap beam 4 is set horizontally and the support column 5 is set vertically. This is a conventional structure for viaducts, and the details will not be elaborated further.

The spraying module 3 is connected and communicates with an external automatic water supply module. The bottom support clamp 1 supports the support frame 2, the support frame 2 supports and installs the spraying module 3, and the spraying module 3 sprays water onto the bottom surface of the cap beam 4 to achieve spraying maintenance of the cap beam 4. The automatic water supply module controls the spraying cycle of the spraying module 3 to achieve automated spraying and avoid the cumbersome manual spraying.

[0050] Reference Figure 1 The bottom support clamp 1 is installed on the outer surface of the upright support column to prevent the support frame 2 and the spray module 3 from falling, thereby ensuring that the water column / mist sprayed by the spray module 3 can contact the bottom surface of the cap beam 4. The distance between the bottom support clamp 1 and the cap beam 4 should be less than the height of the water column / mist sprayed by the spray module 3.

[0051] Reference Figures 1-2 The support frame 2 has a flat frame structure, which facilitates its horizontal installation below the cap beam 4. The support frame 2 is M-shaped and has a first slot 201 and a second slot 202 for horizontally engaging the two vertical support columns, thereby allowing the support frame 2 and the support column 5 to make way for each other, so that the support frame 2 can be located directly below the cap beam 4.

The main rod 21, the central rod group 22, the first edge rod group 23, the second edge rod group 24, the first clamping rod 25, and the second clamping rod 26 are all arranged laterally, thus forming a flat support frame.

[0053] Reference Figure 2 and Figure 3 The central rod assembly 22 is T-shaped connected to the middle of the main rod body 21. One end of the main rod body 21 is L-shaped connected to the first edge rod assembly 23, and the other end is L-shaped connected to the second edge rod assembly 24.

Two first clamping rods 25 are provided and are respectively installed and fixed in the first slot 201 and the second slot 202. Two second clamping rods 26 are provided and are respectively detachably installed at the opening positions of the first slot 201 and the second slot 202. The second clamping rod 26 is inserted into the first slot 201 or the second slot 202 at its middle part.

The first clamping rod 25 and the second clamping rod 26 in the second slot 202 are used to clamp the support column 5 located in the second slot 202 from both sides, thereby achieving horizontal limiting of the present invention, preventing the present invention from moving during the spraying process, and improving the spraying stability.

[0056] Reference Figures 3-5 The first arc-shaped portion 251 and the second arc-shaped portion 261 in the first slot 201 are used to clamp the support column 5 located in the first slot 201 from both sides.

One end of the central horizontal rod 221 is vertically and fixedly connected to the main rod body 21 (e.g., by bolts or welding), and the other end is vertically and fixedly connected to the central vertical rod 222 (e.g., by bolts or welding). The central vertical rod 222 is arranged parallel to the main rod body 21. Several central horizontal rods 221 are arranged in a linear array along the length of the main rod body 21, allowing for the installation of a larger number of branch water pipes 32 and nozzles 321, achieving comprehensive spraying of the bottom surface of the cap beam 4, avoiding blind spots, and improving construction quality.

[0058] Reference Figure 4 and Figure 9 The first edge rod group 23 includes a first horizontal rod 231 and a first vertical rod 232. One end of the first horizontal rod 231 is vertically and fixedly connected to the main rod body 21 (e.g., by bolts or welding), and the other end is vertically and fixedly connected to the first vertical rod 232 (e.g., by bolts or welding). The first vertical rod 232 is arranged parallel to the main rod body 21. Several first horizontal rods 231 are arranged in a linear array along the length of the main rod body 21, allowing for the installation of a larger number of branch water pipes 32 and nozzles 321, achieving comprehensive spraying of the bottom surface of the cap beam 4, avoiding blind spots in the spraying, and improving construction quality.

[0059] Reference Figure 4 and Figure 9 The second edge rod group 24 includes a second horizontal rod 241 and a second vertical rod 242. One end of the second horizontal rod 241 is vertically and fixedly connected to the main rod body 21 (e.g., by bolts or welding), and the other end is vertically and fixedly connected to the second vertical rod 242 (e.g., by bolts or welding). The second vertical rod 242 is arranged parallel to the main rod body 21. Several second horizontal rods 241 are arranged in a linear array along the length of the main rod body 21, allowing for the installation of a larger number of branch water pipes 32 and nozzles 321, achieving comprehensive spraying of the bottom surface of the cap beam 4, avoiding blind spots in the spraying, and improving construction quality.

[0060] Reference Figure 4 The first clamping rod 25 is arranged parallel to the main rod body 21; one end of the first clamping rod 25 is fixedly connected to the central crossbar 221, and the other end is fixedly connected to the first crossbar 231 or the second crossbar 241. One end of the second clamping rod 26 is detachably connected to the central longitudinal rod 222, and the other end is detachably connected to the first longitudinal rod 232 or the second longitudinal rod 242.

[0061] Reference Figure 4For the first clamping rod 25 and the second clamping rod 26 installed in the first slot 201: one end of the first clamping rod 25 is vertically fixedly connected to the central crossbar 221 (e.g., by bolt or by welding), and the other end is vertically fixedly connected to the first crossbar 231 (e.g., by bolt or by welding); one end of the second clamping rod 26 is attached to and detachably connected to the outer wall of the central longitudinal bar 222 (e.g., by bolt), and the other end is attached to and detachably connected to the outer wall of the first longitudinal bar 232 (e.g., by bolt); then the user can easily insert the middle part of the second clamping rod 26 into the first slot 201 and abut against the support column 5, while realizing the temporary installation of its end, and has excellent detachability, thereby improving the efficiency of construction work.

[0062] Reference Figure 4 For the first clamping rod 25 and the second clamping rod 26 installed in the second slot 202: one end of the first clamping rod 25 is vertically fixedly connected to the central crossbar 221 (e.g., by bolt or by welding), and the other end is vertically fixedly connected to the second crossbar 241 (e.g., by bolt or by welding); one end of the second clamping rod 26 is attached to the outer wall of the central longitudinal bar 222 and detachably connected (e.g., by bolt), and the other end is attached to the outer wall of the second longitudinal bar 242 and detachably connected (e.g., by bolt); then the user can easily insert the middle part of the second clamping rod 26 into the second slot 202 and abut against the support column 5, while realizing the temporary installation of its end, and has excellent detachability, thereby improving the efficiency of construction work.

[0063] Reference Figure 6 The support frame 2 also includes reinforcing rods 27. There are two reinforcing rods 27, which are fixedly connected in an inverted V-shape (e.g., by bolts or by welding). The two ends of the main rod 21 are fixedly connected to the two reinforcing rods 27 respectively (e.g., by bolts or by welding) to form a triangular stable support structure. This prevents the main rod 21 from being overloaded and bent near the first slot 201 and the second slot 202, thereby improving the structural strength of the present invention. (If the present invention is inevitably subjected to accidental impact during transportation, storage, and construction, the reinforcing rods 27 can resist the accidental impact to improve the straightness of the main rod 21 and prevent the main rod 21 from being overloaded and bent near the first slot 201 and the second slot 202, which would cause the lateral openings of the first slot 201 and the second slot 202 to close. This ensures that the support column 5 can be smoothly inserted into the first slot 201 / second slot 202.)

[0064] Reference Figure 7The base support clamp 1 includes a first arc plate 11, a second arc plate 12, a first extended fin 13, a second extended fin 14, and a through bolt 15. The inner walls of the first arc plate 11 and the second arc plate 12 can respectively fit and press against the outer wall of the support column 5. One end of the first arc plate 11 and one end of the second arc plate 12 are rotatably connected via a pivot. The end of the first arc plate 11 away from the pivot is fixedly connected to the first extended fin 13 (e.g., through an integral fixed connection), and the end of the second arc plate 12 away from the pivot is fixedly connected to the second extended fin 14 (e.g., through an integral fixed connection). The first extended fin 13 and the second extended fin 14 are detachably connected via the through bolt 15.

[0065] Reference Figure 7 The user wraps the first arc plate 11 and the second arc plate 12 around both sides of the support column 5, and then uses the through bolts 15 to tighten the first extension fin 13 and the second extension fin 14, which can stably clamp the bottom support clamp 1 to the outer wall of the support column 5. The user can remove the through bolts 15 to open the bottom support clamp 1, thereby separating the bottom support clamp 1 from the support column 5, which has an efficient and convenient construction method.

[0066] Reference Figure 7 The inner wall of the first arc plate 11 is provided with a rubber anti-slip layer (e.g., by bonding or by bolting), and the inner wall of the second arc plate 12 is provided with a rubber anti-slip layer (e.g., by bonding or by bolting), thereby improving the friction and installation stability between the bottom support clamp 1 and the support column 5, and preventing the bottom support clamp 1 from sliding down along the support column 5.

[0067] Reference Figure 8 An embedded sleeve 51 is provided inside the support column 5 near its outer surface. The embedded sleeve 51 is cast and fixed inside the support column 5. The steel mesh inside the support column 5 is inserted into the insertion hole of the embedded sleeve 51 to achieve a connection, preventing the embedded sleeve 51 from falling off. The embedded sleeve 51 is arranged radially along the support column 5. The bottom support clamp 1 also includes a bottom support bolt 16. The inner cavity of the embedded sleeve 51 is provided with an internal thread adapted to the external thread of the bottom support bolt 16. The user screws the bottom support bolt 16 into the embedded sleeve 51, and then installs the first arc plate 11 and the second arc plate 12 above the bottom support bolt 16, pressing the first arc plate 11 and the second arc plate 12 against the column head of the bottom support bolt 16. This further prevents the first arc plate 11 and the second arc plate 12 from slipping down, improving the construction stability of this utility model.

[0068] Reference Figure 9For support columns 5 without pre-installed embedded sleeves 51, expansion bolts 17 are installed on their surface, with the expansion bolts 17 arranged radially along the support column 5; the head of the expansion bolt 17 is exposed. When the user installs the first arc plate 11 and the second arc plate 12 above the expansion bolt 17 and presses them against the head of the expansion bolt 17, the problem of the first arc plate 11 and the second arc plate 12 slipping down can be further avoided, improving the construction stability of this invention.

[0069] Reference Figure 10 The sprinkler module 3 includes a main water pipe 31 and a branch water pipe 32, which are connected and interconnected (e.g., through a tee fitting). The main water pipe 31 is installed above the main pole 21, and the branch water pipe 32 is installed above the central crossbar 221, the first crossbar 231, or the second crossbar 241.

[0070] Reference Figure 10 The automatic water supply module includes an external water tank 6, an external water pump 7, a water supply hose 8, and a time relay. The external water tank 6 is connected to the external water pump 7 (e.g., by bolt fixing or by a water pumping pipe). One end of the water supply hose 8 is connected to the external water pump 7 (e.g., by a water pipe fitting) and the other end is connected to the main water pipe 31 (e.g., by a water pipe fitting). The external water pump 7 is electrically connected to the time relay (e.g., by wires and signal lines). The time relay is electrically connected to the external power supply (e.g., by wires and signal lines). The time relay controls the external water pump 7 to start once every 30 minutes, with each start lasting 2-5 minutes. That is, this utility model sprays water onto the bottom surface of the cap beam 4 once every 30 minutes, with each spray lasting 2-5 minutes, thereby achieving spray maintenance on the bottom surface of the cap beam 4.

[0071] The external water tank 6 and external water pump 7 are both located on the ground near the construction node; the length of the water supply hose 8 is not less than the height of the support column 5, so as to match the height of the main water pipe 31; the water supply hose 8 is coiled into a roll when not in use for easy storage.

[0072] Reference Figures 10-12The main water pipe 31 is installed on the upper surface of the main pole 21, and the axis of the main water pipe 31 is set along the length of the main pole 21. The main water pipe 31 is installed by fastening with the first pipe clamp 33. The first pipe clamp 33 is U-shaped and fastens to the outer surface of the main water pipe 31. Both ends of the first pipe clamp 33 are detachably connected to the main pole 21 by bolts, thereby achieving a stable layout of the main water pipe 31. Branch pipe 32 is installed on the upper surface of the central crossbar 221, the first crossbar 231, and the second crossbar 241. The axis of branch pipe 32 is set along the length of the central crossbar 221, the first crossbar 231, and the second crossbar 241. Branch pipe 32 is installed by fastening with second pipe clamp 34. The second pipe clamp 34 is U-shaped and fastens to the outer surface of branch pipe 32. Both ends of the second pipe clamp 34 are detachably connected to the central crossbar 221, the first crossbar 231, and the second crossbar 241 by bolts, thereby achieving stable layout of branch pipe 32.

[0073] The outer wall of the main water pipe 31 is fixedly connected to the inner wall of the first pipe clamp 33 by adhesive (waterproof adhesive) to prevent the main water pipe 31 from rotating.

[0074] Reference Figure 10 One end of the main water pipe 31 is connected to the water supply hose 8, and the other end is sealed (e.g., through an end cap and a sealing ring) to prevent leakage. One end of the branch water pipe 32 is connected to the main water pipe 31, and the other end is sealed (e.g., through an end cap and a sealing ring).

[0075] Reference Figure 1 and Figure 10 A nozzle 321 is installed on the top surface of the branch pipe 32 (for example, through heat fusion for sealing and fixing, or through threads and sealing rings for sealing and fixing). The inner cavity of the nozzle 321 communicates with the inner cavity of the branch pipe 32 and is used to spray water jets / mist. The nozzle 321 points towards the bottom surface of the cover beam 4. The outer wall of the branch pipe 32 is fixedly connected to the inner wall of the second pipe clamp 34 with adhesive (waterproof adhesive), thereby preventing the main water pipe 31 from rotating, and thus keeping the nozzle 321 pointing towards the bottom surface of the cover beam 4 without deviation.

[0077] The main pole 21, the central longitudinal pole 222, the first longitudinal pole 232 and the second longitudinal pole 242 are all equipped with movable wheels on their lower surfaces, so that users can easily push or pull the utility model when it is placed on the ground, thereby improving the ease of construction.

[0079] Reference Figure 13 A first upper abutment rod 2011 is provided above the first slot 201. The first upper abutment rod 2011 is straight, and the first slot 201 and the first upper abutment rod 2011 are arranged in a cross shape. The two ends of the bottom surface of the first upper abutment rod 2011 are vertically and fixedly connected to the top surface of the first crossbar 231 and the top surface of the center crossbar 221, respectively (e.g., by bolts or by welding). When the middle part of the second clamping rod 26 is inserted into the first slot 201, it is located below the first upper abutment rod 2011, and the top surface of the second clamping rod 26 is in contact with the lower surface of the first upper abutment rod 2011. Then, the first upper abutment rod 2011 can apply a downward support force to the second clamping rod 26, avoiding the problem of bending of the waist of the second clamping rod 26 due to the movable setting of the middle part (this bending moment comes from the weight of the center crossbar 221, the first crossbar 231, and the second crossbar 241), thus improving the installation stability of the support frame 2.

[0080] Reference Figure 14 A second upper abutment rod 2021 is provided above the second slot 202. The second upper abutment rod 2021 is straight, and the second slot 202 and the second upper abutment rod 2021 are arranged in a cross shape. The two ends of the bottom surface of the second upper abutment rod 2021 are vertically and fixedly connected to the top surface of the second crossbar 241 and the top surface of the center crossbar 221, respectively (e.g., by bolts or by welding). When the middle part of the second clamping rod 26 is inserted into the second slot 202, it is located below the second upper abutment rod 2021, and the top surface of the second clamping rod 26 is in contact with the lower surface of the second upper abutment rod 2021. Then, the second upper abutment rod 2021 can apply a downward support force to the second clamping rod 26, avoiding the problem of bending of the waist of the second clamping rod 26 due to the movable setting of the middle part of the second clamping rod 26 (this bending moment comes from the weight of the center crossbar 221, the first crossbar 231, and the second crossbar 241), thus improving the installation stability of the support frame 2.

[0081] Since the distance between the bottom support clamp 1 and the cap beam 4 should be less than the height of the water column / mist sprayed by the spray module 3, the water column / mist can contact the bottom surface of the cap beam 4 to achieve spraying. The height of the water column / mist is related to the power of the external water pump 7, the number of nozzles 321, and the inner diameter of the nozzles 321. Therefore, after selecting an external water pump 7 with a fixed power, selecting nozzles 321 with a fixed inner diameter, and installing a fixed number of nozzles 321, a water spray test can be conducted to evaluate the water column spray height H. During construction, the distance between the bottom support clamp 1 and the cap beam 4 needs to be less than H to ensure that the water column can contact the bottom surface of the cap beam 4.

[0082] Usage steps: ① Fix the bottom support clamp 1 to the outer wall of the support column 5; ② Connect the main water pipe 31 to the water supply hose 8; ③ Move the support frame 2 laterally and fasten it to the outer circumference of the support column 5, so that the two support columns 5 are respectively inserted into the first slot 201 and the second slot 202; ④ Move the support frame 2 downward so that the support frame 2 is pressed against the bottom support clamp 1 (refer to...) Figure 4 (1) The first clamping rod 25, the second clamping rod 26, the central crossbar 221, the first crossbar 231, and the second crossbar 241 are pressed onto the top surface of the bottom support clamp 1. 2) The two second clamping rods 26 are respectively installed at the lateral opening positions of the first slot 201 and the second slot 202 and locked with bolts, so that the first clamping rod 25 and the second clamping rod 26 can clamp the limiting support column 5. 3) The time relay is activated, and the external water pump 7 supplies water to the spray module 3 once every 30 minutes, with each water supply lasting 2 to 5 minutes. That is, the spray module 3 sprays water once every 30 minutes, with each spray lasting 2 to 5 minutes.

[0083] This invention features a simple structure and reliable function. A base support clamp 1 is used to install the support frame 2 and the spray module 3 below the cap beam 4. The spray module 3 sprays water upwards to spray the bottom surface of the cap beam 4. An automatic water supply module intermittently supplies water to the spray module 3, achieving intermittent automatic spraying. This invention can adapt to the construction requirements of high-frequency upward spraying, reducing the need for manpower and improving the degree of automation.
