Description

Technical Field

[0001] This application relates to the technical field of building construction pouring devices, and particularly to a guiding structure for concrete pump pipes. Background Art

[0002] Different from the traditional loading method and anchor pile method, the self-balancing method places a load box made according to the bearing capacity parameter requirements at the bottom of the steel reinforcement cage during construction, and sets the pressure oil pipe and displacement measuring device at the top of the steel reinforcement cage. The bottom load box is pressurized by a high-pressure oil pump at the top to obtain the bearing capacity and the total side skin friction. When pouring concrete subsequently, the concrete pump pipe is placed from the top of the steel reinforcement cage and passes through the holes reserved in the load box until the bottom of the steel reinforcement cage. However, since the steel reinforcement cage is buried deep underground, it is very difficult for the concrete pump pipe to accurately align with and pass through the holes, and it requires a crane to hang the pump pipe for multiple blind adjustments and repeated adjustments, resulting in low construction efficiency and inability to meet the on-site requirements. Content of the Utility Model

[0003] In order to improve the problem of low construction efficiency in hoisting the concrete pump pipe in the related art, the present utility model provides a guiding structure for concrete pump pipes.

[0004] A guiding structure for concrete pump pipes includes a main body of a steel reinforcement cage and a load box body arranged on the main body of the steel reinforcement cage. The load box body has a hole, and further includes a guiding assembly arranged on the main body of the steel reinforcement cage. The guiding assembly includes a guiding cylinder body. The guiding cylinder body has a guiding cavity for cooperating with the pump pipe, and the guiding cavity communicates with the hole. The guiding cylinder body includes a plurality of guiding steel bars arranged circumferentially. The plurality of guiding steel bars are inclined. One end in the length direction of the guiding steel bar is connected to the main body of the steel reinforcement cage, and the other end in the length direction of the guiding steel bar converges and is connected to the hole.

[0005] Further, the guiding assembly further includes a first connecting member and a second connecting member arranged on the guiding steel bar. The first connecting member is located at one end where the guiding steel bar cooperates with the main body of the steel reinforcement cage, and the second connecting member is located at one end where the guiding steel bar cooperates with the hole.

[0006] Further, the first connecting member includes a support seat arranged on the guiding steel bar. The support seat is rotatably connected with a rotating block. The rotating block is provided with a hinged block, and the hinged block is hinged with a hook block for cooperating with the guiding steel bar. The hook block hooks or disengages from the guiding steel bar.

[0007] Further, the second connecting member includes an adapted bending piece arranged on the guiding steel bar. The adapted bending piece has a vertical portion, and the vertical portion abuts against the inner wall of the hole.

[0008] Further, the guiding cylinder body includes a number of inner fixing steel bars and a number of outer fixing steel bars for fixing the guiding steel bars. The inner fixing steel bars are arranged on the inner circle of the number of guiding steel bars, and the outer fixing steel bars are arranged on the outer circle of the number of guiding steel bars.

[0009] Further, the reinforcement cage body includes a steel bar main body and support steel bars for supporting the steel bar main body. The support steel bars are fixedly connected to the steel bar main body and extend from one end in the length direction of the steel bar main body to the other end in the length direction of the steel bar main body. The support steel bars are arranged in a spiral shape.

[0010] The present utility model has the following advantages:

[0011] 1. In the concrete pump pipe guiding structure of the present utility model, by arranging a guiding component between the reinforcement cage body and the load box body, the guiding cylinder body is formed by enclosing a number of guiding steel bars to form a funnel-shaped guiding cavity for guiding the pump pipe. During use, the concrete pump pipe is lifted and loaded into the reinforcement cage body. Under the guiding action of the guiding steel bars, the concrete pump pipe can be naturally guided and slide into the hole, enabling the pump pipe to smoothly pass through the hole at one time. At the same time, the structure of the guiding component is compact and easy to use, effectively reducing the installation time, thereby improving the construction efficiency and reducing the construction cost.

[0012] 2. In the concrete pump pipe guiding structure of the present utility model, by arranging a first connecting piece and a second connecting piece, after loading the guiding cylinder body, the guiding steel bars and the steel bar main body are connected by the first connecting piece, and the guiding steel bars and the hole are connected by the second connecting piece.

[0020] In order to make the above objects, features and advantages of the present application more obvious and understandable, the following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0021] In the present application, unless otherwise clearly defined and limited, terms such as "installed", "connected", "connected to", "fixed" and the like shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0022] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0023] Refer to Figure 1, a guiding structure for a concrete pump pipe, comprising a main reinforcement cage body 1 and a load box body 2 arranged on the main reinforcement cage body 1. The main reinforcement cage body 1 has a certain length. The main reinforcement cage body 1 includes a main reinforcement body 11 and support reinforcement bars 12 for the main reinforcement body 11. The main reinforcement body 11 is formed by several reinforcement bars arranged circumferentially. The support reinforcement bars 12 are used to fix and support the several main reinforcement bodies 11. In this embodiment, the support reinforcement bars 12 are fixedly connected to the main reinforcement body 11 and extend from one end in the length direction of the main reinforcement body 11 to the other end in the length direction of the main reinforcement body 11, and the support reinforcement bars 12 are arranged in a spiral shape. It can be understood that the main reinforcement cage body 1 can specifically be an independent reinforcement cage component, and the main reinforcement cage body 1 can also specifically be a part or a component of a foundation pile. The load box body 2 is located at one end in the length direction of the main reinforcement cage body 1, and the load box body 2 has a hole.

[0024] Referring to Figure 1 and Figure 2 , for the convenience of loading the concrete pump pipe, the guiding structure for the concrete pump pipe further includes a guiding component 3 arranged on the main reinforcement cage body 1. The guiding component 3 is used to provide a guiding effect for the concrete pump pipe. When loading the concrete pump pipe, the concrete pump pipe can be quickly and accurately loaded through the guiding component 3. Specifically, the guiding component 3 includes a guiding cylinder body 31. The guiding cylinder body 31 has a guiding cavity for cooperating with the pump pipe, and the guiding cavity is communicated with the hole.

[0025] In this embodiment, the guiding cylinder body 31 includes several guiding reinforcement bars 311 arranged circumferentially. The several guiding reinforcement bars 311 are arranged circumferentially along the inner wall of the main reinforcement body 11, and the several guiding reinforcement bars 311 enclose to form a guiding cavity. The several guiding reinforcement bars 311 are inclined. One end in the length direction of the guiding reinforcement bar 311 is connected to the main reinforcement cage body 1, and the other end in the length direction of the guiding reinforcement bar 311 converges and is connected to the hole. That is, the diameter of the guiding cylinder body 31 gradually increases from the end connected to the load box body 2 to the end away from the load box body 2, which is beneficial to the loading of the concrete pump pipe.

[0026] At the same time, the guiding cylinder body 31 includes several inner fixing reinforcement bars 312 and several outer fixing reinforcement bars 313 for fixing the guiding reinforcement bars 311. The several inner fixing reinforcement bars 312 are arranged along the length direction of the guiding reinforcement bars 311. The inner fixing reinforcement bars 312 are arranged on the inner circle of the several guiding reinforcement bars 311. The inner fixing reinforcement bars 312 can specifically be fixed to the guiding reinforcement bars 311 in the form of welding or threaded connection; correspondingly, the several outer fixing reinforcement bars 313 are arranged along the length direction of the guiding reinforcement bars 311, and the outer fixing reinforcement bars 313 are arranged on the outer circle of the guiding cylinder body 31. Under the action of the inner fixing reinforcement bars 312 and the outer fixing reinforcement bars 313, the several guiding reinforcement bars 311 are fixed and thus have better structural strength, avoiding deformation under pressure when loading the pump pipe.

[0027] To fix the guiding cylinder body 31, the guiding assembly 3 further includes a first connecting member 32 and a second connecting member 33 disposed on the guiding steel bars 311; the first connecting member 32 is located at one end where the guiding steel bars 311 cooperate with the steel bar main body 11, and the second connecting member 33 is located at one end where the guiding steel bars 311 cooperate with the holes.

[0028] Referring to Figure 3 , the first connecting member 32 is used to connect the guiding steel bars 311 and the steel bar main body 11. Since most of the structures on the steel bar main body 11 are non-standard and irregular. To adapt to these structures on the steel bar main body 11, the first connecting member 32 includes a support seat 321 disposed at one end of the guiding steel bars 311. The position of the support seat 321 at one end of the guiding steel bars 311 is within a certain range along the length direction of the guiding steel bars 311, that is, the support seat 321 can be appropriately adjusted along the length direction of the guiding steel bars 311 according to actual needs. The support seat 321 can be specifically installed on the guiding steel bars 311 by means of welding, riveting or threaded connection.

[0029] The support seat 321 is rotatably connected with a rotating block 322. The rotating range of the rotating block 322 is 360 degrees. The rotating block 322 is provided with a hinge block 323, and the hinge block 323 is hinged with a hook block 324 for cooperating with the guiding steel bars 311. By setting the first connecting member 32 in this way, the hinge block 323 and the hook block 324 can be driven to rotate by rotating the rotating block 322, and the hook block 324 can be driven to swing within a certain range by swinging the hinge block 323, so that the hook block 324 can hook or disengage from the guiding steel bars 311. After the guiding cylinder body 31 is installed, by installing and connecting each guiding steel bar 311 through the first connecting member 32, the corresponding end of the guiding cylinder body 31 can be connected with the steel bar main body 11.

[0030] Referring to Figure 2 and Figure 4 , the second connecting member 33 is used to connect the guiding steel bars 311 and the load box body 2. The second connecting member 33 includes an adapted bending piece 331 disposed on the guiding steel bars 311. The adapted bending piece 331 is a spring piece with a bending angle. One end of the adapted bending piece 331 is fixedly connected with the guiding steel bars 311, and the other end of the adapted bending piece 331 has a vertical portion 3311 which penetrates into the hole and abuts against the inner wall of the hole. By setting the second connecting member 33, after the guiding cylinder body 31 is installed, one end of the guiding cylinder body 31 cooperating with the load box body 2 will extend into the hole through the vertical portion 3311 for cooperation, so as to facilitate positioning with the hole and provide a guiding function when the pump pipe is installed.

[0031] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0032] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
