Description

Technical Field

[0001] The utility model relates to the field of magnetic levitation tracks, in particular to a bottom template system for casting a magnetic levitation track beam. Background Art

[0002] The track beam is an important part of the maglev track. It has a track functional surface and a beam or plate structure that bears the train load and transfers it to the supporting structure. In other words, the maglev track beam has the functions of both the beam and the track of a traditional railway. Compared with the operation of traditional rail trains, maglev trains have extremely high requirements for the accuracy of the track beam.

[0003] In the field of high-speed maglev, the distance between the train magnets and the magnets on the track beam directly affects the change in magnetic buoyancy. In order to ensure the smooth development of lift and resistance when the vehicle takes off and lands, and at the same time ensure the riding comfort of the vehicle in the middle section of the line, very strict requirements are placed on the construction accuracy of traditional maglev track beams, which makes it difficult for traditional cast-in-place construction technology to meet this accuracy requirement.

[0004] Based on this, the applicant of this case developed a new type of maglev track beam structure and filed a patent application on the same day as this case; the maglev track beam structure has a propulsion slot in the middle and suspension slots on both sides. By installing a maglev module in the propulsion slot to provide forward power for the train and a maglev module in the suspension slot to provide suspension lift for the train, the stable operation of high-speed maglev vehicles can be met; at the same time, compared with traditional maglev track beams, the precision requirements for cast-in-place construction can be reduced. However, the new type of maglev track beam has an irregular structure and a total height of not less than 4m. The traditional casting process has the defects of severe template deformation and great difficulty in overall cast-in-place. Therefore, the applicant proposed a technical idea of ​​segmented cast-in-place; however, there is no matching mold suitable for the casting of the lower foundation of the segmented cast-in-place maglev track beam in the prior art. Utility Model Content

[0005] The utility model aims to provide a bottom formwork system for casting a maglev track beam in situ, so as to solve the problem in the prior art that there is no matching mold suitable for casting and forming the lower foundation when casting the maglev track beam in situ in sections.

[0006] The utility model is realized by the following technical solutions:

[0007] A bottom formwork system for casting a maglev track beam comprises two mutually parallel side forms, a lower end formwork detachably connected to the axial ends of the two side forms, two basic spacer forms located between the two side forms, and a first L-shaped formwork fixed to the top of the basic spacer forms, wherein a plurality of channels with open bottoms are provided on the basic spacer forms, and the basic spacer forms are parallel to the side forms, and the first L-shaped formwork extends in the lateral outer direction of the corresponding basic spacer forms.

[0008] Aiming at the problem that there is no matching mold suitable for casting and forming the lower foundation when the maglev track beam is cast in sections in the prior art, the utility model proposes a bottom template system for casting the maglev track beam in place, wherein the lower end mold is located at the axial ends of the maglev track beam, and the basic partition mold is used to distinguish the different areas corresponding to the push groove and the suspension groove of the maglev track beam; the bottom of the channel thereon is open, so as to ensure that when pouring concrete, the concrete can quickly and smoothly fill the internal space of the lower mold group; the first L-shaped mold includes two mutually perpendicular surfaces, wherein the one side surface directly connected to the basic partition mold is perpendicular to the basic partition mold and extends laterally outward, and the other side surface is parallel to the basic partition mold and extends upward, such an arrangement can make the two first L-shaped molds jointly form the bottom structure of the middle push groove of the special-shaped maglev track beam (because the push groove depth is greater than the suspension groove depth), and can provide a positioning basis for the installation of the push groove mold in the upper mold group, which is conducive to ensuring the continuity of the two casting operations. The lateral outer side of the basic spacer mold refers to a side of the basic spacer mold that is away from the direction where another basic spacer mold is located in a direction perpendicular to the axial direction.

[0009] The detachable connection in the present application can be realized by any detachable connection method in the prior art; in addition, the support, stabilization and other technologies of each template can be realized by the prior art.

[0010] Furthermore, it also includes a first place-occupying tube fixedly connected between the two basic spacer molds, and a plurality of first place-occupying tubes are evenly distributed along the axial direction between the two basic spacer molds.

[0011] In this scheme, a plurality of through holes facing the propulsion grooves can be formed on the bottom plate of the maglev track beam through the first placeholder tube. Such through holes can effectively reduce the stress concentration phenomenon below the propulsion groove of the maglev track beam; at the same time, it is beneficial to ensure the balance of temperature, humidity, pressure, etc. inside and outside the propulsion groove, which is more conducive to the maglev test section track simulating actual wilderness conditions.

[0012] Furthermore, the first placeholder tube is at the same height as the basic spacer mold, and the top height of the first placeholder tube is lower than the top height of the first L-shaped mold; this solution is used to ensure that after the track beam is formed, the through hole facing the propulsion groove is effectively connected with the propulsion groove, and to ensure that the propulsion groove has a flat bottom.

[0013] Furthermore, the first placeholder tube is square in shape, and the edges of the first placeholder tube are rounded, which further reduces the stress concentration phenomenon in the lower foundation after molding.

[0014] Furthermore, it also includes a second placeholder tube located between the basic partition mold and the side mold on the same side, and the second placeholder tube is at the same height as the first L-shaped mold.

[0015] This solution can form several through holes on the bottom plate of the maglev track beam facing the suspension groove through the second placeholder tube. Such through holes can effectively reduce the stress concentration phenomenon under the suspension groove of the maglev track beam; at the same time, it is conducive to ensuring the balance of temperature, humidity, pressure, etc. inside and outside the suspension groove, which is more conducive to the maglev test section track simulating actual wilderness conditions. The second placeholder tube is at the same height as the first L-shaped mold, which can ensure that after the track beam is formed, the through holes facing the suspension groove are effectively connected to the suspension groove.

[0016] Furthermore, a first positioning protrusion is arranged on the top of the second placeholder tube, and a second positioning protrusion corresponding to the first positioning protrusion is arranged on the top of the first L-shaped mold; first threaded through holes matching each other are opened on the first positioning protrusion and the second positioning protrusion, and the first positioning protrusion and the second positioning protrusion are connected by bolts.

[0017] Unlike the first placeholder tube that can be limited by the basic spacer molds on both sides, the second placeholder tube in the present application is located between the basic spacer mold and the side mold and is not in direct contact with the basic spacer mold and the side mold. Therefore, it is difficult to position and install the second placeholder tube, and it is difficult to ensure the stability of each second placeholder tube during the casting process. In order to overcome the above-mentioned defects, the present scheme provides a first positioning protrusion and a second positioning protrusion that are opposite to each other on the top of the second placeholder tube and the top of the first L-shaped mold, respectively, and provides a first threaded through hole on both positioning protrusions, and then screws matching bolts into the first threaded through holes on the first positioning protrusion and the second positioning protrusion and locks them. The second placeholder tube can be limited by the basic spacer mold and the first L-shaped mold, thereby ensuring the rapid positioning and installation of the second placeholder tube, while avoiding shaking or displacement of each second placeholder tube during the casting process. In addition, for maglev track beams of different models or sizes, the lateral position of the second placeholder tube may also be different. The present solution can flexibly adjust the lateral relative position of the second placeholder tube and the basic partition mold before pouring through the connection method of positioning protrusions and bolts, thereby further broadening the versatility of the present application.

[0018] Furthermore, it also includes an internal top mold for being placed on the top of the basic partition mold and between the two first L-shaped molds.

[0019] Since the pouring height of the outside of the foundation partition mold is higher than the pouring height of the inside of the foundation partition mold, an internal top mold is used to prevent the liquid level of concrete in the foundation partition mold from being too high; the two first L-shaped molds form two step surfaces, and the two sides of the internal top mold can be installed on the step surfaces on both sides, thereby limiting the concrete forming height inside the foundation partition mold and ensuring that the depth of the propulsion groove is greater than the depth of the suspension groove, which is convenient for the later installation of different magnetic levitation modules.

[0020] Furthermore, it also includes a lower top mold for being placed on the top of the first L-shaped mold and / or the second placeholder tube.

[0021] The present solution further provides a lower top mold placed on the top of the first L-shaped mold and / or the second placeholder tube, which is beneficial to improving the flatness of the molded concrete inside the lower mold group and is more conducive to the subsequent installation of the upper mold group.

[0022] Furthermore, the lower top mold is provided with a plurality of first through grooves for the first positioning protrusion to pass through and a plurality of second through grooves for the second positioning protrusion to pass through; the groove width of the first through groove is equal to the width of the first positioning protrusion, the groove width of the second through groove is equal to the width of the second positioning protrusion, and the long axes of the first through groove and the second through groove are both perpendicular to the axial direction of the side mold; and the lower top mold is also provided with a plurality of grouting holes.

[0023] Considering the existence of the first positioning protrusion, the second positioning protrusion and the matching bolts, if the positioning protrusion and the bolts are blocked by the lower top mold after the installation, the position of the second placeholder tube can no longer be adjusted and confirmed, which is not conducive to the final review of the position of each second placeholder tube before pouring. Therefore, this scheme also opens the first through groove and the second through groove on the lower top mold; before installing the bolts, the lower top mold is installed in place first, and the first positioning protrusion passes through the first through groove and the second positioning protrusion passes through the second through groove during the process. The staff can determine the relative position of the second placeholder tube below and the basic partition mold through the position of the first positioning protrusion and the second positioning protrusion, and then finally review the position of each second placeholder tube before pouring. In addition, the first threaded through holes are all located above the lower top mold, and the staff can install the corresponding bolts above the lower top mold, and the shape of the lower structure of the maglev track beam after the lower casting will not be affected by the existence of the bolts. In addition, the first positioning protrusion can move laterally in the first through groove, and the second positioning protrusion can move laterally in the second through groove, thereby ensuring effective adjustment of the relative position of the second place-occupying tube and the basic spacer mold; at the same time, it plays an axial limiting role for the second place-occupying tube and the basic spacer mold. In addition, the gravity of the lower top mold acts on the first L-shaped mold and / or the second place-occupying tube, which can also stabilize the first L-shaped mold and / or the second place-occupying tube, and further ensure the structural stability during the pouring and waiting process.

[0024] Furthermore, the lower top form and the side form are both steel formworks to improve the flatness of the foundation surface after forming, so as to facilitate the next stage of cast-in-place operation thereon.

[0025] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0026] 1. The utility model provides a bottom formwork system for casting a maglev track beam, which realizes the cast-in-place operation of the lower foundation when casting a large-height maglev track beam in stages, overcomes the defects of difficult cast-in-place operation and serious formwork deformation caused by the excessively large overall height of the maglev track beam, and fills the gap in the prior art.

[0027] 2. The utility model provides a bottom formwork system for cast-in-place maglev track beams, which can effectively reduce the stress concentration phenomenon in the lower part of the maglev track beams; at the same time, it is beneficial to ensure the balance of temperature, humidity, pressure, etc. inside and outside, and is more conducive to simulating actual wilderness conditions in the maglev test section track.

[0028] 3. The utility model provides a bottom formwork system for cast-in-place maglev track beams, which can limit the second placeholder tube by means of a base spacer mold and a first L-shaped mold, so as to ensure rapid positioning and installation of the second placeholder tube, while avoiding shaking or displacement of the second placeholder tubes during the pouring process; the lateral relative position of the second placeholder tube and the base spacer mold can also be flexibly adjusted before pouring, thereby further broadening the versatility of the present application.

[0029] 4. The utility model provides a bottom formwork system for cast-in-place of a maglev track beam, which can finally check the position of each second placeholder tube before pouring, and can effectively adjust the relative position of the second placeholder tube and the basic partition formwork.
