Description

Technical Field

[0001] The invention belongs to the field of pipeline installation, and specifically relates to a grid conversion system and a pipeline arrangement method. Background Art

[0002] If mechanical and electrical pipeline points are not reserved in the terminal roof during the early construction period, it will be very difficult to add various pipelines according to usage needs during the operation stage (such as new fume exhaust pipes for catering needs), which is not conducive to improving the airport service quality and operating efficiency. Therefore, it is very necessary to reserve mechanical and electrical pipeline points in the terminal roof during the early construction period.

[0003] At present, the terminal building roof under construction often adopts steel grid structure. The integrity and integrity requirements of the grid structure are very strict. The only external force points in the grid are points such as steel structure ball nodes. The layout of electromechanical pipelines in the grid is particularly dense and complex. If the traditional method of directly welding the electromechanical pipeline bracket (such as U-shaped frame) to the steel structure rotating rod to fix the electromechanical pipeline is adopted, it has the following disadvantages:

[0004] First, the brackets are fixed on the steel structure rotating rod, which makes it difficult to determine the spacing between the brackets. There is a problem of too large spacing, which is not conducive to the installation and fixation of electromechanical pipelines. In addition, the installation of pipelines on the steel structure chord affects the stress of the grid, and the vibration of the pipelines during construction and operation also affects the user experience.

[0005] Second, the grid construction site is complex and changeable, and there are problems such as inconsistency in the size and shape of the various electromechanical pipeline brackets. The electromechanical pipeline brackets cannot be set in a standard and standardized manner, which brings inconvenience to processing and construction;

[0006] Third, electromechanical pipeline supports are usually used when electromechanical pipelines are installed, which makes it inconvenient to reserve points for later reconstruction and expansion.

[0007] In summary, for steel grid structures, the installation and fixation of electromechanical pipelines and the later reservation of electromechanical pipelines become construction problems. Summary of the invention

[0008] The purpose of the present invention is to provide a grid conversion system, which can not only ensure the integrity of the grid structure, but also meet the installation requirements of electromechanical pipelines, while taking into account the points reserved for later use.

[0010] Furthermore, the vertical bracket includes a vertical hanger and a connecting steel plate, the bottom end of the vertical hanger is connected to the center of the top surface of the connecting steel plate, and the top end is connected to the top spin ball; the end of the conversion beam is supported on the top surface of the connecting steel plate, and the end of the conversion beam is fixed to the connecting steel plate by connecting bolts.

[0011] Furthermore, an ear plate is fixedly connected to the bottom of the topspin ball, and the top end of the vertical suspension rod is hung on the ear plate.

[0012] Furthermore, a reinforcing plate is provided on the bottom surface of the connecting steel plate.

[0013] Furthermore, the transverse support includes a pull rod, a clamp 1 and a clamp 2, wherein the clamp 1 is fixed to one end of the pull rod, and the clamp 2 is fixed to the other end of the pull rod; the clamp 1 is embraced on the lower spin rod of the top spin ball, and the clamp 2 is embraced on the end of the conversion beam.

[0014] Furthermore, taking the plane where the conversion beam frame is located as the projection plane, the conversion beams constituting the two sides of each corner of the conversion beam frame are conversion beam one and conversion beam two respectively; the orthographic projection of the lower rotation rod two on the projection plane is located between conversion beam one and conversion beam two; the orthographic projection of the lower rotation rod one on the projection plane is located outside the conversion beam one, and the orthographic projection of the lower rotation rod three on the projection plane is located outside the conversion beam two; the transverse bracket includes four tie rods, three clamps one and two clamps two; the three clamps one are respectively surrounded by the lower rotation rod one, the lower rotation rod two and the lower rotation rod three; the two clamps two are respectively surrounded by the conversion beam one and the conversion beam two; the clamp one on the lower rotation rod one is connected to the clamp two on the conversion beam one through a tie rod; the clamp two on the conversion beam one is connected to the clamp one on the lower rotation rod two through a tie rod; the clamp one on the lower rotation rod two is connected to the clamp two on the conversion beam two through a tie rod; the clamp two on the conversion beam two is connected to the clamp one on the lower rotation rod three through a tie rod.

[0015] Furthermore, the conversion beam is a square steel pipe.

[0016] Furthermore, a U-shaped hanger is arranged at the bottom of the conversion beam arranged along the transverse direction on the conversion beam frame, and the U-shaped hanger on the conversion beam arranged along the transverse direction forms a transverse channel for accommodating the passage of the transverse pipeline; a U-shaped hanger is arranged at the bottom of the conversion beam arranged along the longitudinal direction on the conversion beam frame, and the U-shaped hanger on the conversion beam arranged along the longitudinal direction forms a longitudinal channel for accommodating the passage of the longitudinal pipeline.

The conversion beam frame is connected to the corresponding topspin ball through a vertical bracket, and the topspin ball bears the force, which has little effect on the force of the grid. In summary, the grid conversion system disclosed in the present invention can not only ensure the integrity of the grid structure, but also meet the installation requirements of electromechanical pipelines, while taking into account the reserved points for later periods.

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0030] The terms "top", "bottom", "outside", "longitudinal", "lateral", "vertical", "one end" and "the other end" used in the present invention to indicate directions are based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] Grid conversion system, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the grid 1 is a ball node grid, wherein four topspin balls 11 are distributed at the four corners of a square, and each topspin ball 11 is connected to a backspin rod 12, a backspin rod 2 13 and a backspin rod 3 14; a horizontally arranged conversion beam frame 2 is arranged below the four topspin balls 11, and the conversion beam frame 2 is a square frame surrounded by conversion beams 21; the four corners of the conversion beam frame 2 are respectively located below the corresponding topspin balls 11, and are connected to the corresponding topspin balls 11 via vertical brackets 3; transverse brackets 4 are respectively arranged at the four corners of the conversion beam frame 2, and the transverse brackets 4 are connected between the conversion beam 21 and the backspin rod on the corresponding topspin ball 11; a transverse channel for accommodating the passage of a transverse pipeline and a longitudinal channel for accommodating the passage of a longitudinal pipeline are arranged at the bottom of the conversion beam frame 2, and the transverse channel and the longitudinal channel are arranged in a vertical staggered manner.

[0032] In the present invention, the transfer beam frame 2 is used for the layout of electromechanical pipelines, which include air ducts, electromechanical pipelines, and cable trays. The electromechanical pipelines extending longitudinally pass through the longitudinal channel, and the electromechanical pipelines extending transversely pass through the transverse channel. The transverse channel and the longitudinal channel are arranged in a vertically staggered manner, which means that the transverse channel is located above the longitudinal channel, or the transverse channel is located below the longitudinal channel, and the two do not interfere with each other.

[0033] The conversion beam frame 2 is connected to the corresponding topspin ball 11 through the vertical bracket 3. The force of the conversion beam frame 2 is transmitted to the topspin ball 11 through the vertical bracket 3. The topspin ball 11 bears the force, which has little effect on the force of the grid 1. In addition, the vertical brackets 3 are only set at the four corners of the conversion beam frame 2, which has a simple structure and little impact on the space. The horizontal bracket 4 connects the conversion beam 21 of the conversion beam frame 2 with the downspin rod, which improves the stability and reliability of the installation of the conversion beam frame 2.

[0034] The transfer beam 21 constituting the transfer beam frame 2 can be made of a round steel pipe, an angle steel, an I-beam, etc. In this embodiment, the transfer beam 21 is made of a square steel pipe, which is light and easy to install. The transfer beam 21 can be made of a section of square steel pipe, or it can be made of multiple sections of square steel pipes. The transfer beam frame 2 can be a square-shaped outer frame surrounded by only four transfer beams 21. Of course, the internal transfer beams 21 can also be arranged in the outer frame to form a field-shaped frame, etc. The number of corresponding transfer beams 21 can be increased or decreased according to actual needs.

[0035] The vertical bracket 3 can be in various forms, for example, a suspension rod can be directly used as the vertical bracket, with the bottom end fixed to the conversion beam 21 and the top end fixed to the top spin ball 11. Figure 6 As shown, the vertical bracket 3 includes a vertical suspension rod 31 and a connecting steel plate 32. The bottom end of the vertical suspension rod 31 is connected to the center of the top surface of the connecting steel plate 32, and the top end is connected to the top spin ball 11; the end of the conversion beam 21 is supported on the top surface of the connecting steel plate 32, and the end of the conversion beam 21 and the connecting steel plate 32 are fixed by connecting bolts 5. The installation of the conversion beam 21 is achieved by connecting the steel plate 32, which is convenient for installing the conversion beam 21. During installation, the conversion beam 21 is first placed on the top surface of the connecting steel plate 32, and then the conversion beam 21 is fixed to the connecting steel plate 32 by connecting bolts 5 through corresponding bolt holes. One connecting steel plate 32 simultaneously supports the ends of two conversion beams 21, and the structure is simple.

[0036] An ear plate 11A is fixedly connected to the bottom of the top spin ball 11, and the top end of the vertical suspension rod 31 is hung on the ear plate 11A. This arrangement allows the vertical suspension rod 31 to be connected to the top spin ball 11 without welding.

[0037] In order to reinforce the connecting steel plate 32 , a reinforcing plate 33 is provided on the bottom surface of the connecting steel plate 32 .

[0038] In order to achieve a welding-free connection between the transverse support 4 and the grid 1, and between the transverse support 4 and the conversion beam frame 2, the transverse support 4 includes a pull rod 41, a clamp 1 42 and a clamp 2 43, wherein the clamp 1 42 is fixed to one end of the pull rod 41, and the clamp 2 43 is fixed to the other end of the pull rod 41; the clamp 1 42 is encircled on the lower spin rod of the top spin ball 11, and the clamp 2 43 is encircled on the end of the conversion beam 21.

[0039] like Figure 5 As shown, taking the plane where the conversion beam frame 2 is located as the projection plane, the conversion beams 21 constituting the two sides of each corner of the conversion beam frame 2 are conversion beam one 21A and conversion beam two 21B respectively; the orthographic projection of the lower rotary rod two 13 on the projection plane is located between the conversion beam one 21A and the conversion beam two 21B; the orthographic projection of the lower rotary rod one 12 on the projection plane is located outside the conversion beam one 21A, and the orthographic projection of the lower rotary rod three 14 on the projection plane is located outside the conversion beam two 21B. With such an arrangement, the conversion beam frame 2 makes full use of the space of the grid 1 itself, and at the same time greatly shortens the fixed distance between the grid 1 and the conversion beam frame 2, so that the support for the pipeline can be designed in a more standard and standardized manner.

[0040] A pull rod and two hoops can be provided between each conversion beam 21 and the corresponding lower rotating rod, so a total of 8 hoops are needed, and two hoops are provided at one end of each conversion beam 21. The more hoops there are, the more space the conversion beam 21 is occupied, which will affect the installation of the pipeline channel. In order to avoid the above problems, in this embodiment, the transverse bracket 4 includes four pull rods 41, three clamps 1 42 and two clamps 2 43; the three clamps 1 42 are respectively encircled by the lower rotation rod 1 12, the lower rotation rod 2 13 and the lower rotation rod 3 14; the two clamps 2 43 are respectively encircled by the conversion beam 1 21A and the conversion beam 2 21B; the clamp 1 42 on the lower rotation rod 12 is connected with the clamp 2 43 on the conversion beam 1 21A through one of the pull rods 41; the clamp 2 43 on the conversion beam 1 21A is connected with the clamp 1 42 on the lower rotation rod 2 13 through one of the pull rods 41; the clamp 1 42 on the lower rotation rod 2 13 is connected with the clamp 2 43 on the conversion beam 2 21B through one of the pull rods 41; the clamp 2 43 on the conversion beam 2 21B is connected with the clamp 1 42 on the lower rotation rod 3 14 through one of the pull rods 41. In this way, a pair of transverse brackets 4 is an integral whole, which consumes less materials, occupies less space, and has better integrity.

[0041] A U-shaped hanger 22 is provided at the bottom of the transversely arranged transfer beam 21 on the transfer beam frame 2, and the U-shaped hanger 22 on the transversely arranged transfer beam 21 forms the transverse channel for the transverse pipeline to pass through in the transverse direction;

[0042] A U-shaped hanger 22 is provided at the bottom of the transfer beam 21 arranged in the longitudinal direction on the transfer beam frame 2, and the U-shaped hanger 22 on the transfer beam 21 arranged in the longitudinal direction forms the longitudinal channel for accommodating the longitudinal pipeline to pass through in the longitudinal direction.

[0043] The pipeline layout method using the above-mentioned grid conversion system includes the following steps:

[0044] Step 1: Install the vertical bracket 3 and the horizontal bracket 4 on the grid 1;

[0045] Step 2: Place the two ends of the conversion beam 21 of the conversion beam frame 2 on the top surface of the connecting steel plate 32 of the corresponding vertical bracket 3, and fix the end of the conversion beam 21 and the connecting steel plate 32 by connecting bolts 5; and use the transverse bracket 4 to connect the conversion beam 21 of the conversion beam frame 2 with the lower rotating rod 1 12, the lower rotating rod 2 13 and the lower rotating rod 3 14; install the U-shaped hanger 22 at the bottom of the conversion beam 21 to form a transverse channel and a longitudinal channel;

[0046] Step 3: Pass the horizontal pipeline through the horizontal channel; pass the vertical pipeline through the vertical channel.

[0047] In the description of this specification, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
