Description

Technical Field

[0001] The utility model relates to the technical field of pipe gallery installation frames, in particular to an assembled integral concrete pipe gallery installation frame. Background Art

[0002] In the prior art, a pipeline system needs to be built in a chemical plant for conveying gas materials (or liquid materials). Generally, it can be installed by pre-embedding or installed on the ground through a pipe gallery installation frame. Installing it on the ground can facilitate subsequent inspection and maintenance. The pipe gallery installation frame can generally adopt a steel structure, which can shorten the construction period and has good structural strength. However, in some factories that convey corrosive materials, it is inevitable that corrosive materials will leak accidentally, which will cause the pipe gallery installation frame to be corroded. Therefore, maintenance is required, which is time-consuming and has high maintenance costs. In the prior art, a reinforced concrete structure can also be used to construct a pipe gallery installation frame, which can have better corrosion resistance and only requires light maintenance, reducing the cost of maintenance. However, the reinforced concrete structure cannot be built high and there is a risk of collapse. Therefore, there will be fewer pipes installed on the pipe gallery installation frame, so it is necessary to build multiple parallel pipe gallery installation frames, which will occupy a large amount of factory space. At the same time, the construction period is also longer, which will lead to an increase in the overall construction cost. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an assembled integral concrete pipe gallery installation frame, which solves the problems of high construction cost and large floor space of the reinforced concrete pipe gallery installation frame in the prior art.

[0005] In the above embodiment, the prefabricated concrete parts used in the main structure can be installed during construction, which can shorten the construction period. At the same time, in terms of height, the overall structure is made higher by setting connecting columns and top columns. The first upper crossbeam, the first lower crossbeam and the second lower crossbeam can be used for the installation of pipelines, which increases the amount of pipeline installation. Therefore, the number of pipeline gallery installation frames can be reduced, thereby reducing the floor space occupied, and finally solving the problem of high construction cost and large floor space occupied by reinforced concrete pipeline gallery installation frames in the prior art.

[0006] Furthermore, a plurality of first steel bars are respectively reserved at the top of the base column and the top of the connecting column, and a plurality of second steel bars corresponding to the first steel bars are respectively embedded in the bottom ends of the connecting column and the top column. A sleeve is also respectively provided outside each second steel bar, and a corresponding first steel bar can be inserted into the sleeve from bottom to top.

[0007] Furthermore, the two connecting columns, the first upper crossbeam and the first lower crossbeam are integrated prefabricated parts.

[0008] Furthermore, the two top columns, the second upper cross beam and the second lower cross beam are integrated prefabricated parts.

[0009] Furthermore, the upper end of the sleeve is conical and surrounds the second steel bar, and the lower end is straight and surrounds the first steel bar, and the upper and lower ends of the sleeve are respectively provided with a grouting port and a grouting port.

The mounting groove passes through the second base and extends downward into the first base.

[0013] Furthermore, the upper opening of the installation groove is larger than the bottom thereof.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] By setting the main structure as prefabricated concrete parts and installing them on site, the construction period can be shortened. At the same time, the overall structure has a higher height while ensuring strength, and more pipes can be installed, thereby increasing the amount of pipe installation, which can reduce the number of pipe gallery installation frames to be built, thereby reducing the floor space occupied, and ultimately solving the problems of high construction cost and large floor space occupied by reinforced concrete pipe gallery installation frames in the prior art.

DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] In an exemplary embodiment, Figure 1-3 As shown, this embodiment provides an assembled integral concrete pipe gallery installation frame, which includes a pair of vertically opposed base columns 1, and two connecting columns 2 respectively connected to the top ends of the two base columns 1, and top columns 3 respectively connected to the top ends of the two connecting columns 2, the upper and lower ends of the two connecting columns 2 are respectively fixedly connected with a first upper cross beam 4 and a first lower cross beam 5, the upper and lower ends of the two top columns 3 are respectively fixedly connected with a second upper cross beam 6 and a second lower cross beam 7, the base column 1, the connecting column 2, the top column 3, the first upper cross beam 4, the second upper cross beam 6, the first lower cross beam 5 and the second lower cross beam 7 are all prefabricated concrete parts; it also includes a pair of bases 16 for installing the two base columns 1 respectively.

[0024] In the above embodiment, the main structure adopts concrete prefabricated parts, wherein the two connecting columns 2 and the first upper crossbeam 4, the first lower crossbeam 5, and the two connecting top columns 3 and the second upper crossbeam 6, the second lower crossbeam 7 are respectively integrated prefabricated parts. During construction, the prefabricated parts can be installed, which can shorten the construction period. At the same time, in terms of height, the setting of the connecting columns 2 and the top columns 3 makes the height of the overall structure higher. The set first upper crossbeam 4, the first lower crossbeam 5 and the second lower crossbeam 7 can be used for pipeline installation, which increases the amount of pipeline installation. Therefore, the number of pipe gallery installation frames to be built can be reduced, thereby reducing the occupied area, and finally solving the problem of high construction cost and large occupied area of ​​reinforced concrete pipe gallery installation frames in the prior art; more specifically, in this solution, the first upper crossbeam 4, the second upper crossbeam 6, the first lower crossbeam 5 and the second lower crossbeam 7 can strengthen the connection strength between the connecting columns 2 on both sides and between the top columns 3, thereby making the overall structure stronger.

[0025] like Figure 1-3As shown, in a further exemplary scheme, the top of the base column 1 and the top of the connecting column 2 are respectively reserved with a plurality of first steel bars 9, and the bottom ends of the connecting column 2 and the top column 3 are respectively pre-embedded with a plurality of second steel bars 10 corresponding to the first steel bars 9, and each second steel bar 10 is also respectively sleeved with a sleeve 11, and a corresponding first steel bar 9 can be inserted into the sleeve 11 from bottom to top, that is, the second steel bar 10 and the sleeve 11 are preset in the lower ends of the top column 3 and the connecting column 2. During on-site installation, the corresponding connecting column 2 is lifted by a lifting machine, and the sleeve 11 on the connecting column 2 is aligned with the first steel bar 9 so that the first steel bar 9 enters the corresponding sleeve 11, and then the slurry discharge port 18 set at the upper and lower ends of the sleeve 11 is passed. The grouting operation is performed through the grouting port 19, so that high-strength concrete (such as C85 high-strength concrete) is filled in the sleeve 11. With the assistance of the sleeve 11, a high-strength connection structure is formed outside the first steel bar 9 and the second steel bar 10, so that the first steel bar 9 and the second steel bar 10 are connected, so that stable installation is achieved between the connecting column 2 and the base column 1, and between the connecting column 2 and the top column 3; in a more specific scheme, a sealing mortar layer 17 is further provided between the connecting column 2 and the base column 1, and between the connecting column 2 and the top column 3. The setting of the sealing mortar layer 17 can be after the first steel bar 9 and the second steel bar 10 are butt-jointed (that is, before the sleeve 11 is grouted), specifically, at the connection (between the connecting column 2 and the base column 1, or between the connecting column 2 and the top column 3). A reinforcing strip is added to improve the strength of the reinforced connection before the construction is completed (after the construction is completed, the reinforcing strip can be removed). At this time, a gap is left between the upper and lower structures of the connection, so that concrete (it can also be C85 high-strength concrete) can be poured into the gap to form a sealing layer 17 after solidification, and then the sleeve 11 is grouted. Specifically, the grouting port 19 is located at the lower end of the sleeve 11, and the slurry discharge port 18 is set at the upper end, and the sealing layer 17 closes the lower end of the sleeve 11. During grouting, after the concrete enters, it first flows downward and connects with the sealing layer 17, and then gradually flows upward, and finally is discharged from the slurry discharge port 18, thereby filling the entire sleeve 11 structure; further, reinforcing strips are also arranged between multiple sleeves 11. The fixed steel bar 12 can strengthen the sleeve 11. More specifically, the first steel bar 9 is formed by extending the steel bars in the base column 1 and the connecting column 2 outward, and is integrated with the internal structure of the prefabricated part. Similarly, the second steel bar 10 is also integrated with the internal structure of the prefabricated part. The second steel bar 10 and the sleeve 11 can be welded or threaded. More specifically, the upper end of the sleeve 11 is tapered and the lower end is a larger straight cylinder. The upper end of the sleeve 11 is tapered and surrounds the lower end of the second steel bar 10 and is fixed by welding (or threaded), so that part of the second steel bar 10 is located therein, and the lower end of the sleeve 11 is larger to allow the first steel bar 9 below to enter smoothly, thereby facilitating the docking of the upper and lower structures.

[0026] like Figure 1-3 As shown, in a further exemplary scheme, mounting grooves 14 are respectively recessed on the two bases 16, and the bottom ends of the two columns 1 are respectively inserted into the two mounting grooves 14, and the bottom ends of the columns 1 are fixed in the mounting grooves 14 by concrete, thereby achieving fixed installation of the columns 1. In a more detailed implementation scheme, similarly, the base 16 is also a prefabricated part that is pre-set, and the corresponding column 1 is inserted during installation and then concrete is poured. In a further implementation scheme, a support member 13, such as a pair of square steel bars, is also provided between the inner bottom surface of the mounting groove 14 and the column 1. During construction, the support member 13 raises the bottom end of the column 1 in the mounting groove 14, so that there is a gap between the column 1 and the inner bottom surface, so that the lower end of the column 1 can be wrapped to a greater extent during concrete pouring, thereby achieving a more stable connection with the base 16.

[0027] like Figure 1 As shown, further, in the components of the present scheme, each pipe gallery installation frame includes two bases 16, two base columns 1, and an integrated connecting column 2, a first upper cross beam 4, a first lower cross beam 5, and a top column 3, a second upper cross beam 6, and a second lower cross beam 7. The number of components is small, and the size of the two integrated components is just right to be transported by existing transport vehicles, without the need for extra-wide vehicles, so the transportation cost will not be increased; in the two integrated components, the connection column 2 and the first upper cross beam 4, the first lower cross beam 5, and the top column 3 and the second upper cross beam 6, the second upper cross beam 7 are At the connection nodes between them, the interior is connected by structural steel bars, and then cast in one piece through a mold, finally forming an integrated component, which can better bear the installation load; during the specific construction: first connect the base column 1 and the corresponding base 16 (the connection is completed after grouting with C85 high-strength concrete), then hoist the two connecting columns 2 and the first upper beam 4 and the first lower beam 5, and then grout the sleeve 11, and then hoist the two top columns 3 and the second upper beam 6 and the second lower beam 7, and then grout the sleeve 11 to complete the construction, and the construction period can be greatly shortened.

[0028] like Figure 3As shown in more detail, the base 16 includes a first base 15, and a second base 8 integrally cast on the first base 15, the first base 15 and the second base 8 are coaxially arranged and the orthographic projection of the second base 8 is located at the center of the top surface of the first base 15, the mounting groove 14 passes through the second base 8 and extends downward into the first base 15, and the base 16 is arranged as a structure that is small at the top and large at the bottom as a whole, so that the center of gravity of the entire base 16 can be moved downward, and at the same time, the bottom area is larger, and the overall stability of the base 16 after installation is better, and the mounting groove 14 extends to the first base 15, so that after the base column 1 is installed, the bottom of the base column 1 also extends into the first base 15, and at the same time, the entire periphery of the bottom of the base column 1 The high-strength concrete is wrapped so that the column 1 can be stably installed in the base 16; in more detail, the upper end opening of the installation groove 14 is larger than its bottom, the base 16 is cast in one piece, and the internal installation groove 14 is also formed at the same time. The installation groove 14 is arranged in this way, which is larger at the top and smaller at the bottom. The corresponding mold can be smoothly lifted up and demoulded, which is convenient for the prefabrication of the base 16. At the same time, after such arrangement, the high-strength concrete wrapped outside the column 1 is also correspondingly thicker at the top, forming an inclusion body that is larger at the top and smaller at the bottom. The inclusion body can exert a force downward on the inner wall of the installation groove 14, thereby making the inclusion body and the base 16 more tightly combined, and the overall structure is further strengthened.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
