Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an installation structure for the pre-embedded construction of large pipe sections. Background Technology

[0002] In underground construction, due to the complexity and diversity of pipeline systems, pipe sections are usually pre-embedded in concrete walls to facilitate easy connection of adjacent pipes located on the inside and outside of the walls during subsequent construction, ensuring the smooth operation of the pipeline system.

[0003] In the existing technology, the pre-installation of pipe sections in underground buildings is generally carried out by using lifting equipment to hoist them to the steel reinforcement skeleton in the concrete shear wall, and then connecting them to the steel reinforcement skeleton in the wall in a suspended state to form support for the pipe section; or the pipe section is hoisted to the wall formwork support by using lifting equipment during the wall formwork erection, and the wall formwork support is used to support the pipe section. However, the above construction methods have the following defects: (1) When the concrete of the wall is poured, the steel reinforcement skeleton or the wall formwork support will be deformed by the load disturbance, which will cause the pipe section to shift, resulting in hidden dangers in the installation quality; (2) When encountering the pre-installation of large pipe sections, the steel reinforcement skeleton or the wall formwork support in the wall cannot bear the weight load of the pipe section itself. Forcibly fixing it will not only cause hidden dangers in quality, but also cause greater safety hazards.

[0004] Therefore, it is necessary to improve the existing construction methods for pre-embedded large pipe sections so that they can effectively solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an installation structure for the pre-embedded construction of large pipe sections. Based on the structural characteristics of the pre-embedded flange of the pipe section, the pre-embedded fixing is carried out by means of an external installation frame, which can effectively ensure the accuracy of the pre-embedded flange and greatly reduce the safety hazards in the construction process.

[0006] This utility model provides an installation structure for the pre-embedded construction of large pipe sections, including an inner mounting frame disposed inside the shear wall and an outer mounting frame disposed outside the shear wall. A support assembly for supporting the installation of the large pipe section is disposed between the inner mounting frame and the outer mounting frame. The support assembly includes a support rod erected between the inner mounting frame and the outer mounting frame. The support rod has mounting parts for installing the large pipe section disposed at flange faces on both sides of the axial direction of the large pipe section.

[0007] Furthermore, the support rod is installed perpendicular to the shear wall surface, and the central axis of the support rod along its own length direction coincides with the central axis of the large pipe section.

[0008] Furthermore, the mounting component includes at least two connecting rods extending radially toward the flange face from the center of the flange face. One end of the connecting rod is fixedly connected to the support rod, and the other end of the connecting rod is fixedly connected to the flange face.

[0009] Furthermore, the connecting rod has a mounting hole at its end located on the flange face for connecting and fixing to the flange face, and the mounting hole corresponds one-to-one with the connecting hole on the flange face.

[0010] Furthermore, the two connecting rods located on the flange faces on both sides of the large pipe section are fixedly connected to the large pipe section by the same bolt assembly passing through the mounting holes of both.

[0011] Furthermore, inclined support frames are provided between the top of the inner mounting frame and the ground, and between the top of the outer mounting frame and the ground.

[0012] Furthermore, frame embedded parts are provided between the bottom of the inner mounting frame and the ground, between the bottom of the outer mounting frame and the ground, and between the bottom of the inclined support frame and the ground.

[0013] The beneficial effects of this utility model are as follows: The installation structure of this utility model for the pre-embedded construction of large pipe sections, based on the structural characteristics of the flanges on the large pipe sections, sets support frames on both axial sides of the large pipe section and uses the bolt connection holes on the flange surfaces on both sides of the large pipe section to independently and reliably fix the large pipe section, effectively ensuring the accuracy of the pre-embedded flanges in the concrete shear wall and greatly reducing safety hazards during construction; at the same time, after the construction is completed, the support frames can be recycled and reused, reducing material waste.

Detailed Implementation

[0019] As shown in the figure, this utility model provides an installation structure for the pre-embedded construction of large pipe sections, including an inner mounting frame 2 located inside the shear wall and an outer mounting frame 3 located outside the shear wall. A support assembly for supporting the installation of the large pipe section 1 is provided between the inner mounting frame 2 and the outer mounting frame 3. The support assembly includes a support rod 4 erected between the inner mounting frame 2 and the outer mounting frame 3. The support rod 4 has mounting parts for installing the large pipe section 1 at flange positions on both sides of the axial direction of the large pipe section 1. The inner side of the shear wall refers to the interior of a room, and the outer side of the shear wall refers to the exterior of a room. Therefore, the inner mounting frame 2 is correspondingly located inside the room, and the outer mounting frame 3 is correspondingly located outside the room. However, since the large pipe section 1 is located in an underground structure, the definitions of "inside" and "outside" are selected according to the actual design. In this solution, according to... Figure 2 As shown, the inner installation frame 2 is located on the left side of the large pipe section 1, and the outer installation frame 3 is located on the right side of the large pipe section 1. Further details are omitted here. Both the inner installation frame 2 and the outer installation frame 3 are constructed by splicing square steel tubes to form a frame structure, respectively positioned on both axial sides of the large pipe section 1 to ensure balanced installation force and high load-bearing capacity. Frames are installed on both axial sides of the large pipe section 1, with support rods 4 between them. Mounting components are installed on the support rods 4 near the flange face of the large pipe section 1. Through the cooperation of the mounting components, support rods 4, and installation frames, the large pipe section 1 is independently and reliably fixed, avoiding damage to the reinforcing steel frame or wall formwork support. Simultaneously, it effectively prevents the concrete pouring of the wall from disturbing or shifting the position of the large pipe section 1, effectively ensuring the accuracy of the embedded flange of the pipe section within the concrete shear wall.

[0020] In this embodiment, the support rod 4 is installed perpendicular to the shear wall surface, and the central axis of the support rod 4 along its length direction coincides with the central axis of the large pipe section 1; combined with Figure 1 and Figure 2 As shown, the support rod 4 is made of square steel tubing. The support rod 4 is a single rod with both ends mounted on the top surfaces of the inner mounting frame 2 and the outer mounting frame 3, respectively. The central axis of the support rod 4 along its length is aligned with the central axis of the large pipe section 1 to ensure that the distance from the mounting parts on the support rod 4 to the flange surface of the large pipe section 1 is consistent, thereby ensuring the stress balance of the large pipe section 1.

[0021] In this embodiment, the mounting component includes at least two connecting rods 5 extending radially toward the flange surface from the center of the flange surface. One end of each connecting rod 5 is fixedly connected to the support rod 4, and the other end of each connecting rod 5 is fixedly connected to the flange surface. Figure 1As shown, the mounting component is made of C-shaped steel and includes at least two connecting rods 5. Although one connecting rod 5 can support the installation of the large pipe section 1, the number of connecting rods 5 cannot be less than two due to considerations of load-bearing safety and force balance. The arrangement of the connecting rods 5 can be designed according to the actual situation, such as a "V" shaped structure or an "X" shaped structure, which will not be elaborated here. In this scheme, the connecting rods 5 are arranged in a "+" shaped structure mainly because the support rod 4 is made of square tube steel, and the four sides of the square tube steel are more conducive to the welding and fixing between the connecting rod 5 and the support rod 4. Therefore, the "+" shaped structure of the mounting component in this scheme is formed.

[0022] In this embodiment, the connecting rod 5 has a mounting hole 6 at its end located on the flange face for connecting and fixing to the flange face, and the mounting hole 6 corresponds one-to-one with the connecting hole 7 on the flange face; combined with Figure 1 As shown, the connecting rod 5 has mounting holes 6 at its end located on the flange face that correspond one-to-one with the connecting holes 7 on the flange face. Thus, the connecting rod 5 can be directly connected and fixed to the connecting rod 5 using the connecting holes 7 on the structure of the large pipe section 1 itself. This can effectively ensure the accuracy of the flange pre-embedding and greatly reduce safety hazards during construction.

[0023] In this embodiment, two connecting rods 5 located on the flange faces on both sides of the axial direction of the large pipe section 1 are fixedly connected to the large pipe section 1 by the same bolt assembly 8 passing through the mounting holes 6 of both; combined with Figure 1 and Figure 2 As shown, since the connecting holes 7 on the flanges on both sides of the large pipe section 1 are one-to-one in the axial direction, the positions of the connecting rods 5 on both sides of the axial direction of the large pipe section 1 and the positions of the mounting holes 6 on the connecting rods 5 are also one-to-one. In this solution, the same bolt assembly 8 passes through the mounting holes 6 on the connecting rods 5 on both sides of the axial direction of the large pipe section 1 and the connecting holes 7 on the flanges in sequence, which can realize the fixed connection of the large pipe section 1 and also achieve the effect of installation, clamping and positioning of the large pipe section 1 on both sides of the axial direction.

[0024] In this embodiment, inclined support frames 9 are provided between the top of the inner mounting frame 2 and the ground 11, and between the top of the outer mounting frame 3 and the ground 11; combined with Figure 1 and Figure 2 As shown, since the inner mounting frame 2 and the outer mounting frame 3 are only connected by support rods 4, inclined support frames 9 are respectively provided between the top of the inner mounting frame 2 and the ground 11 and between the top of the outer mounting frame 3 and the ground 11 to strengthen the support of the inner mounting frame 2 and the outer mounting frame 3, thereby improving the support strength of the large pipe section 1 and avoiding safety hazards.

[0025] In this embodiment, frame embedded parts 10 are provided between the bottom of the inner mounting frame 2 and the ground 11, between the bottom of the outer mounting frame 3 and the ground 11, and between the bottom of the inclined support frame 9 and the ground 11; combined with Figure 3 As shown, the bottom of the inner mounting frame 2 is fixed to the ground 11 through the frame embedded part 10, the bottom of the outer mounting frame 3 is fixed to the ground 11 through the frame embedded part 10, and the bottom of the inclined support frame 9 is fixed to the ground 11 through the frame embedded part 10. The frame embedded part 10 is a support plate, and the support plate is fixed to the ground 11 through the anchor bar.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
