Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for building pouring, and in particular to a device and method for reinforcing the horizontal section of an ultra-high pressure pump pipe. Background Technology

[0002] For super high-rise buildings exceeding 200 meters in height, ultra-high-pressure concrete pump trucks are required during concrete pouring. The standard pump pipes used in conjunction with these trucks must be replaced with ultra-high-pressure pipes to withstand the increased conveying pressure. A horizontal pipeline of a certain length exists between the concrete pump truck and the vertical pump pipe to provide sufficient resistance to prevent concrete backflow. The layout of the horizontal pipeline should minimize its adverse impact on the construction site, and its length should be kept as short as possible. However, to reduce the pressure generated by the weight of the concrete, the total length of the horizontal pipeline should not be less than 1 / 5 of the height of the vertical pipeline. Furthermore, according to technical requirements for ultra-high-pressure pumping, the most important point is that the horizontal pump pipes must not shift during the pumping process (i.e., they must remain in a fixed position).

[0003] Traditional methods use cast-in-place reinforced concrete piers to fix horizontal pump pipes, with the concrete pier height not exceeding 50 cm. Figure 1 and Figure 2 As shown, concrete piers have significant limitations in vertical height. If the vertical distance between the horizontal pump pipe and the floor slab is greater than 50 cm, the concrete pier will be larger than 50 cm. This results in a larger pier volume and self-weight, which not only wastes a lot of steel bars and concrete, but also takes too long to process. Furthermore, there are safety hazards such as insufficient floor slab bearing capacity due to the increased self-weight of the pier. Summary of the Invention

[0004] To address the various problems caused by existing horizontal pump pipes being more than 50 cm above the floor slab, this invention provides a device and method for reinforcing the horizontal section of an ultra-high pressure pump pipe.

[0005] The technical solution of the present invention is achieved through the following scheme: a horizontal section reinforcement device for ultra-high pressure pump pipes, comprising a plurality of high pressure pump pipes, a bearing platform for supporting the high pressure pump pipes, and a limiting member for applying a locking force to the high pressure pump pipes. The bearing platform is overlapped at the intersection of two horizontal sections of the high pressure pump pipes. The limiting members are installed on both sides of the intersection of the horizontal sections of the high pressure pump pipes. The intersection of the horizontal sections of the high pressure pump pipes is connected to the bearing platform through the limiting members. The limiting members are adjustablely connected to the bearing platform through locking nuts.

[0006] The limiting member is provided with a limiting arc surface that is adapted to the outer surface of the pump pipe, and the bearing platform includes a supporting steel plate, which is used to directly or indirectly abut against the horizontal section of the high-pressure pump pipe.

[0007] Preferably, the bearing platform further includes a straight section of round steel and a fixed bracket. The straight section of round steel is obliquely inserted into the support steel plate, and the straight section of round steel is fixedly connected to the fixed bracket. The intersection of the horizontal sections of the high-pressure pump pipe is abutted against the support steel plate by a limiting member.

[0008] Preferably, the fixing bracket is fixedly connected to the floor slab base by chemical anchors, the fixing bracket is inverted "T" shape, and the limiting member is "U" shaped round steel.

[0009] Preferably, the support platform also includes scaffolding, and the supporting steel plate is connected to the intersection of the horizontal sections of the high-pressure pump pipe via the scaffolding.

[0010] The specific steps of the method for reinforcing the horizontal section of the ultra-high pressure pump pipe are as follows:

[0011] Step A: Erect scaffolding according to the actual height and relevant specifications to pre-support the high-pressure pump pipe;

[0012] Step B: Select an appropriate reinforcement method based on the location between the horizontal section of the high-pressure pump pipe and the scaffolding.

[0013] Preferably, in step B, when the intersection of the horizontal sections of the high-pressure pump pipe is located at the scaffolding, the specific reinforcement steps include:

[0014] b1. Drill straight holes in the support steel plate according to the diameter of the straight part of the limiting component;

[0015] b2, further overlap the outer surfaces on both sides of the intersection of the arc-shaped parts of the two limiting parts and the horizontal section of the high-pressure pump pipe;

[0016] b3, the supporting steel plate passes through the straight part of the limiting member. At this time, the scaffolding part is in the limiting space, and the supporting steel plate completes the support for the high pressure pump pipe.

[0017] b4. Further adjust the support steel plate to the appropriate position and reinforce it by tightening the lock nut.

[0018] Preferably, in step B, when the intersection of the horizontal sections of the high-pressure pump pipe is far from the scaffolding, the specific reinforcement steps include:

[0019] b1, according to the diameter of the straight part of the limiting component, open a straight hole in the supporting steel plate, and according to the diameter of the round steel in the straight section, open 45° oblique holes at the four corners of the supporting steel plate;

[0020] b2, further overlap the outer surfaces on both sides of the intersection of the arc part of the two limiting parts and the horizontal section of the high-pressure pump pipe, and the supporting steel plate passes through the straight part of the limiting part and is tightened by the lock nut;

[0021] b3. Thread one end of the straight section of round steel and insert the threaded end into the 45° inclined hole of the support steel plate at an angle. Pre-fix it with the lock nut and do not tighten it for the time being.

[0022] b4, The non-threaded end of the straight section of round steel is welded to the fixed bracket, and the excess straight section of round steel is cut off;

[0023] b5, holes are drilled at the four corners of the fixed bracket, and it is fixed to the floor base with chemical anchors;

[0024] b6, at this point, tighten the lock nut on the threaded end of the straight section of the round steel to make it taut, thus completing the corner reinforcement;

[0025] b7, the four straight sections of round steel are all welded and fixed to the four fixed brackets in this manner.

[0026] Preferably, in step b4, the fixing bracket is made of two steel plates welded vertically, and the straight section of round steel is welded to the vertical steel plate in the fixing bracket.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. This invention uses recyclable components such as round steel, nuts, and steel plates, which can save resources to the greatest extent, reduce the overall cost, effectively improve the fixing efficiency of horizontal pump pipes, save concrete strength curing time, and save a lot of steel bars and concrete. It is also better recyclable than concrete steel reinforcement piers.

[0029] 2. By using different types of connection methods and optimized support structures, the system is ensured to remain stable during operation and to provide good support for the foundation and overall structure.

[0030] 3. By making full use of the structure and components of the scaffolding, effective support for the horizontal section of the high-pressure pump pipe was achieved, while reducing resource waste and improving reinforcement efficiency and safety.

[0031] 4. By adopting this lightweight design, the load on the surrounding environment or supporting structure of the device is effectively reduced, and potential safety hazards are reduced. The use of different reinforcement devices with different structures according to the distance from the scaffolding effectively increases applicability. Attached Figure Description

Detailed Implementation

[0040] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein. Therefore, the invention is not limited to the specific embodiments disclosed in the following specification. The invention will be further described in detail below with reference to the accompanying drawings.

[0042] Example 1: A reinforcement device for the horizontal section of an ultra-high pressure pump pipe, such as Figure 3-7As shown, the system includes several high-pressure pump pipes 1, a support platform 2 for supporting the high-pressure pump pipes 1, and limiting members 3 for applying locking force to the high-pressure pump pipes 1. The support platform 2 overlaps at the intersection of horizontal sections of two high-pressure pump pipes 1. Limiting members 3 are installed on both sides of the intersection of horizontal sections of the high-pressure pump pipes 1. The intersection of horizontal sections of the high-pressure pump pipes 1 is connected to the support platform 2 via the limiting members 3. The limiting members 3 are adjustable to the support platform 2 via locking nuts 6. The limiting members 3 have limiting arc surfaces adapted to the outer surface of the pump pipes. The support platform 2 includes a supporting steel plate 21, which is used to directly or indirectly abut against the intersection of horizontal sections of the high-pressure pump pipes 1. The casting pump pipe is composed of several high-pressure pump pipes 1. The high-pressure pump pipe 1 is reinforced at the intersection of horizontal sections. Compared with traditional concrete piers, it can effectively improve the fixing efficiency of horizontal pump pipes, save concrete strength curing time, and save a lot of steel bars and concrete. Since components such as round steel, nuts, and custom steel plates can be recycled, resources can be saved to the greatest extent and the overall cost can be reduced. The reinforcement devices with different structures are used according to the distance from the scaffold 24 to effectively increase applicability. The limiting part 3 is a "U" shaped round steel and is set on both sides of the intersection. The straight section round steel 22 and the limiting part 3 are fixed with double locking nuts 6 to effectively increase the locking force and the stability of the bearing platform 2. All workpieces are made of 22-type round steel.

[0043] When away from the scaffolding 24, the supporting platform 2 also includes straight sections of round steel 22 and fixed supports 23. Straight sections of round steel 22 are obliquely inserted into the supporting steel plate 21, and are fixedly connected to the fixed supports 23. At the intersection of the horizontal sections of the high-pressure pump pipe 1, a limiting element 3 abuts against the supporting steel plate 21. The fixed supports 23 are fixedly connected to the floor slab base 4 via chemical anchors 5. The fixed supports 23 are inverted "T" shaped. The structure's stability is increased through multiple connections using the limiting element 3 and the 45° obliquely inserted straight sections of round steel 22. And to ensure that the support system remains stable when facing pressure or load when away from the scaffolding 24, the support steel plate 21 adopts a specification of 400x200x16. The inverted "T" design of the fixed bracket 23 is easy to install and provides sufficient support area, disperses the load and provides uniform support, increases the system's adaptability to different stresses and the stability of the overall structure. At this time, the support steel plate 21 not only has straight holes that cooperate with the limiting parts 3, but also has 45° oblique holes at the four corners to facilitate the insertion of straight section round steel 22.

[0044] When located on scaffold 24, the bearing platform 2 also includes scaffold 24. The supporting steel plate 21 abuts against the intersection of the horizontal section of the high-pressure pump pipe 1 through the scaffold 24. While providing pre-support, the scaffold 24 uses some of its horizontal bars to lock with the supporting steel plate 21 and the limiting member 3 to provide strong support for the intersection of the horizontal section of the high-pressure pump pipe 1. This effectively utilizes environmental resources while simplifying the entire structure, reducing the number of required components, and lowering costs. At this time, the supporting steel plate 21 adopts a specification of 200x200x12.

[0045] The other locations of the horizontal pump pipe are fixed in this way, avoiding safety hazards such as insufficient bearing capacity of the floor slab base 4 due to the increased self-weight of the pier column, thereby improving the safety of the horizontal section reinforcement of the ultra-high pressure pump pipe 1, effectively controlling the project cost, and achieving efficient, fast and safe construction.

[0046] Example 2: A method for reinforcing the horizontal section of an ultra-high pressure pump pipe, such as... Figure 3-7 As shown, the reinforcement steps include the following:

[0047] Step A: Erect scaffolding 24 according to the actual height and relevant specifications to pre-support the high-pressure pump pipe 1;

[0048] The high-pressure pump pipe 1 may impact the ground or other equipment. The pre-supported scaffolding 24 can mitigate or disperse these impact forces to a certain extent, helping to protect the integrity of the high-pressure pump pipe 1 and surrounding equipment and extend the equipment life.

[0049] Step B: Select a suitable reinforcement method based on the location between the intersection of the horizontal section of the high-pressure pump pipe 1 and the scaffold 24.

[0050] In step B, when the intersection of the horizontal sections of the high-pressure pump pipe 1 is located at scaffold 24, the specific reinforcement steps include:

[0051] b1. Drill a straight hole in the support steel plate 21 according to the diameter of the straight part of the limiting member 3;

[0052] b2, further overlap the outer surfaces on both sides of the intersection of the arc-shaped parts of the two limiting parts 3 and the horizontal section of the high-pressure pump pipe 1;

[0053] b3, the supporting steel plate 21 passes through the straight part of the limiting member 3, at this time the scaffold 24 part is in the limiting space, and the supporting steel plate 21 completes the support for the high pressure pump pipe 1;

[0054] b4. Further adjust the support steel plate 21 to a suitable position and reinforce it by tightening the locking nut 6.

[0055] By cleverly utilizing the 24 components of the scaffolding, support can be provided at intersections, reducing material waste.

[0056] In step B, when the intersection of the horizontal sections of the high-pressure pump pipe 1 is far from the scaffold 24, the specific reinforcement steps include:

[0057] b1, according to the diameter of the straight part of the limiting member 3, a straight hole is opened in the supporting steel plate 21, and according to the diameter of the round steel 22 of the straight section, 45° oblique holes are opened at the four corners of the supporting steel plate 21.

[0058] b2, further overlap the outer surfaces on both sides of the intersection of the arc part of the two limiting parts 3 and the horizontal section of the high-pressure pump pipe 1, and the supporting steel plate 21 passes through the straight part of the limiting part 3 and is tightened by the locking nut 6;

[0059] b3, thread one end of the straight section round steel 22, and insert the threaded end obliquely into the 45° oblique hole of the support steel plate 21, and pre-fix it with the lock nut 6, without tightening it for the time being;

[0060] b4, the non-threaded end of the straight section of round steel 22 is welded to the fixed bracket 23, and the excess straight section of round steel 22 is cut off;

[0061] b5, holes are made at the four corners of the fixed bracket 23, and it is fixed to the floor base 4 by chemical anchor bolts 5;

[0062] b6, at this time, tighten the locking nut 6 on the threaded end of the straight section of round steel 22 to make it taut, thus completing the corner reinforcement;

[0063] b7, the four straight sections of round steel 22 are all welded and fixed to the four fixed brackets 23 in this manner.

[0064] In step b4, the fixed bracket 23 is made of two steel plates welded vertically. The unthreaded end of the straight section round steel 22 is welded to the vertical steel plate in the fixed bracket 23. The horizontal steel plate and the floor base 4 are fixedly connected by chemical anchors 5. The weld is ≥240mm. It can be disassembled simply by cutting it off. It is easier to recycle than concrete piers.

[0065] Compared to traditional methods such as pouring concrete, the reinforcement process of this device is relatively simple, including steps such as opening holes in the straight section of round steel 22, overlapping the limiting piece 3, passing through the straight section of the limiting piece 3, threading, and welding, which effectively increases work efficiency.
