Integral transfer straddle-type monorail PC track beam template

[0022] The present invention will be further described in detail below through specific embodiments in conjunction with the drawings.

[0023] Considering the single applicability of the existing formwork system, which is only suitable for PC beams of equal height, an integrally movable straddle monorail PC track beam formwork is proposed. The template system can be used to prefabricate large, medium and small-sized PC track beams of equal height and variable height within 30m. At the same time, when the control elevation of the top surface of the longitudinal centerline of the bottom of the beam is determined, the template can be rotated as a whole to form the required track line shape, which improves the operability and efficiency of beam manufacturing during beam manufacturing. If you keep the beam section unchanged (such as image 3 , Figure 5 (Shown) The line shape required by the curve is formed only by the way of integral rotation. At the same time, when the beam part changes in height along the bridge, the bottom mold of the formwork can be adjusted according to the curve needs, so that the beam body is simple and convenient to manufacture, and the line shape is beautiful. The design idea of ​​the new template.

[0024] An integral transfer type straddle type monorail PC track beam template, such as figure 1 , As shown in 2, it includes: bottom mold 1, side mold 3, positioning column 4, joist 7, horizontal sliding rod 9;

[0025] The bottom mold 1 is set on the height-adjustable bracket 2. The side molds 3 are set on both sides of the bottom mold 1. The two side molds 3 are parallel to each other and are in contact with the bottom mold 1; the two side molds 3 are respectively equipped with positioning Column, the outside of the side mold 3 is fixedly connected with the positioning column; the space enclosed by the bottom mold 1 and the two side molds 3 is the production area of ​​the straddle-type monorail PC track beam;

[0026] Height adjustable bracket 2, two positioning columns are both standing on the joist 7 and connected with the joist 7; the joist 7 is above the traverse slide bar 9, and the joist 7 and the traverse slide bar 9 are partially stacked up and down , The superimposed position is connected by a rotatable pin 8 and the non-superimposed end of the joist 7 and the non-superimposed end of the lateral sliding rod 9 are respectively connected to the adjacent positioning pillars 4 through a telescopic drive.

[0027] The bottom mold 1 is set on the height-adjustable bracket 2. In actual operation, it can be adjusted according to the height requirements of the PC beam; at the same time, the space enclosed by the side mold 3 and the bottom mold 1 is made of straddle-type monorail PC track beam Zone, during production, the plane of the PC beam can be determined through this zone; then the position of the joist 7 and the traverse slide bar 9 can be adjusted by the pivotable pin 8 to rotate the enclosed zone as a whole to form the required track Linear, ultra-high structure can also be produced. It facilitates the manufacture of PC beams and improves manufacturing efficiency.

[0028] Next, describe the template in detail:

[0029] The integrally movable straddle type monorail PC track beam formwork mainly realizes the controllable section and the overall movable. In order to achieve this purpose, it is mainly composed of bottom mold 1, side mold 3, positioning column 4, joist 7, and horizontal movement It consists of 9 slide bars. Wherein, the two ends of the bottom mold 1 are respectively provided with side molds 3, and the two side molds 3 are parallel to each other, and respectively contact with both ends of the bottom mold 1, so that the bottom mold 1 and the side mold 3 form a PC track beam to form a closed space. In order to make the section of the space controllable, the two side molds 3 are respectively fixed by positioning uprights, and the side molds 3 are fixedly connected to the corresponding positioning uprights; and the bottom mold 1 is set on a height-adjustable bracket 2. The height-adjustable bracket 2Similar to a bench shape, the height can be changed according to the design requirements of the beam body to form the required line shape. The height of the beam plane can be determined by adjusting the height adjustable bracket 2. Determine the shape of the bridge section to be consistent with the design section. The two positioning columns and the height-adjustable bracket 2 are both beneficial to the lower joist 7 and are connected with the joist 7 to increase stability. Below the joist 7 is set a transverse sliding rod 9, a joist 7 and a transverse sliding Part of the rod 9 is superimposed up and down, and the superimposed part is connected by a rotatable pin 8. The non-superimposed end of the joist 7 and the non-superimposed end of the horizontal sliding rod 9 are respectively connected to the respective adjacent positioning columns 4 by a telescopic drive. . Through the rotation of the retractable driving member and the rotatable pin 8, the bottom mold 1 and the side mold 3 can be driven to rotate as a whole to form a desired linear shape.

[0030] In order to wrap the PC beam more closely, the bottom of the side mold 3 is lower than the plane where the bottom mold 1 is located.

[0031] In order to increase the accuracy of production, it is necessary to use the longitudinal centerline 5 of the straddle monorail PC track beam as a reference. The positioning columns are parallel to each other when the beam body is manufactured. Make the top surface of the beam perpendicular to the longitudinal centerline 5.

[0032] When the pin shaft 8 is located on the longitudinal center line 5, it is more stable when the whole is transferred and the balance is stronger.

[0033] In some embodiments, the telescopic driving member can be a screw rod 6 or a driving cylinder. Both the screw rod 6 and the driving cylinder are used to provide a telescopic driving force to increase or shorten the distance between them.

[0034] In order to change the distance more stably, the screw rod 6 is connected with the middle part of the positioning column 4, and the middle part of the positioning column 4 is supported for stronger stability.

[0035] Theoretically speaking, only the positioning column 4 and the joist 7 are fixedly connected, in order to prevent accidental deflection of the upper part in the integral mobile type. Therefore, the bottom end of the positioning column 4 connected to the horizontal sliding rod 9 through the telescopic drive member is fixedly connected with the joist 7. At the same time, in order to facilitate demolding, the positioning column 4 connected with the joist 7 through a retractable driving member has its bottom end hinged with the joist 7. When demolding, the nut and the rod corresponding to the screw 6 of the positioning column 4 are separated, the positioning column 4 is rotated, and the PC beam is demolded.

[0036] At the same time, in order to facilitate the sliding of the transverse slide bar 9, it also includes: a transverse slide rail beam 10, a slide groove is provided on the transverse slide rail beam 10, and the transverse slide bar 9 slides in the slide groove to guide the transverse slide bar 9Slide on the established track. The transverse slide beam 10 is fixed on the ground and is the main support of the formwork system.

[0037] The advantages of this technology are:

[0038] 1. Adopting the formwork system of "adjustable bottom mold, side mold and bottom mold mode", suitable for large, medium and small straight curve PC track beams.

[0039] 2. The prefabrication of variable height PC track beam can be realized according to the different adjustable bottom molds, which improves the aesthetics of the beam body.

[0040] 3. The applicable span range of PC track beam is generally within 30m, and the minimum applicable curve radius is 40m.

[0041] 4. Adopting the side mold and the bottom mold method, the bottom mold and the side mold can be adjusted to cooperate with the production prefabrication of the PC track beam of various types of monorail vehicles.

[0042] 5. The beam is made by means of integral rotation of the template, which improves the operability of the template and improves the efficiency of beam making.

[0043] 6. Realize the design of the same cross-section straight and curved track beam template.

[0044] 7. The problem of the bottom surface of the beam is solved, and the landscape of the bridge in the city is improved.
