Detailed Description

The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.

As shown in fig. 1 to 3, a novel form support for road and bridge construction comprises a connecting seat 1 and a top brace 2, wherein the connecting seat 1 comprises an upper connecting cylinder 11 and a lower connecting cylinder 12, the bottom end of the upper connecting cylinder 11 is connected with the top end of the lower connecting cylinder 12, one end of the top brace 2 is movably arranged in the upper connecting cylinder 11, a through hole for the filler in the upper connecting cylinder 11 to pass through is formed in the lower part of the outer wall of the upper connecting cylinder 11, a baffle 13 matched with the through hole is arranged at the through hole, and the baffle 13 is rotatably connected with the side wall of the upper connecting cylinder 11; one end of the lower connecting cylinder 12 far away from the upper connecting cylinder 11 is movably connected with a movable shaft 3 for connecting a support steel pipe. This support is used for when the cast-in-place box girder construction of bridge, and is used to the support of case roof beam bottom surface template, and this support lies in than ordinary support, can directly separate support and template through highly adjusting self, has avoided the damage to cast-in-place box girder concrete when dismantling: when needs form removal, only need open baffle 13, put out through the opening filler in with the hollow cavity of last connecting cylinder 11, then shore 2 moves down in last connecting cylinder 11's hollow cavity, and then shore 2 is separated with the template, take off the template can.

Further, in the concrete implementation process of the support in construction, when a bottom formwork of a cast-in-place box girder needs to be supported, firstly, a certain amount of filler which can be compacted and compacted, such as sand, is filled in the cavity of the upper connecting cylinder 11 of the connecting base 1 of the support, the filler is compacted and compacted, in order to ensure that the filler filled in the cavity of the upper connecting cylinder 11 can be discharged, a through hole for the filler in the upper connecting cylinder 11 to pass through is formed in the lower part of the outer wall of the upper connecting cylinder 11 of the support, in the implementation process, a through hole for the filler in the upper connecting cylinder 11 to pass through is formed in the lower part of the outer wall of the upper connecting cylinder 11, the through hole is not limited to the lower part of the outer wall of the upper connecting cylinder 11, and the through hole can be formed in a position where the filler can be discharged to enable the top brace 2 to leave the formwork; and this through hole department be equipped with the baffle 13 of through hole adaptation, baffle 13 pivoted and the lateral wall of last connecting cylinder 11 are connected, specific connected mode can be: one side end of the baffle 13 is connected with the side wall of the upper connecting cylinder 11 through a rotating shaft in a rotating manner, one end, far away from the rotating shaft, of the baffle 13 is connected with a limiting plate 131, the limiting plate 131 is provided with a channel, and the side wall of the upper connecting cylinder 11 is provided with a limiting groove 14 which is matched with the limiting plate 131 and used for limiting the limiting plate 131; the designed limiting plate 131 can be movably arranged in the limiting groove 14, the limiting groove 14 is provided with a limiting hole in a penetrating way, the limiting hole is provided with a pin shaft 141 in a penetrating way, one end of the pin shaft 141 can movably penetrate through a channel formed in the limiting plate 131, and iron nails 142 used for limiting are movably arranged at two ends of the pin shaft in a penetrating way. When up connecting cylinder 11 inside packing filler, need block up the opening with baffle 13, avoid the filler to spill, so in the operation, rotate baffle 13, let baffle 13 keep away from the limiting plate 131 card that rotates the end in spacing groove 14, then pass spacing groove 14 and the limiting plate 131 of card in spacing groove 14 with round pin axle 141, spacing about reuse iron nail 142 carries out limiting plate 131, avoids limiting plate 131 not hard up. In order to support template and template seam crossing that can be better, the one end of keeping away from connecting seat 1 at shore 2 is connected with a fagging 21, and fagging 21 can increase the area of contact, supports the seam of two templates, and the quality of pouring is influenced in the dislocation of template.

Further, a support steel pipe is arranged on the movable shaft 3 in a penetrating mode and used for supporting the template. This 3 hollow settings of loose axle, the one end that connecting cylinder 12 was used for wearing to establish the support steel pipe under the loose axle 3 kept away from, and the outer wall of loose axle 3 rotates through the screw thread to be connected with fine setting swivel cap 31, after having supported the bottom surface template through the step above, carries out the elevation confirmation to the template of support before pouring, if there is the discrepancy in elevation, finely tunes the swivel cap 31 through the rotating and finely tunes the template of support, and then reachs the elevation requirement of design. Because the concrete that pours is more, this support need bear great upper portion load, and the influence of the power that considers bearing to this support is whole, is connected with support disc 121 in the bottom outer wall of lower connecting cylinder 12, and support disc 121 is used for contacting with fine setting swivel cap 31, increases with fine setting swivel cap 31 support area.

Further, when needs form removal, only need take off the iron nail 142 at round pin axle 141 both ends, take off round pin axle 141, rotating baffle 13, spill the opening, then with the filler in connecting cylinder 11 on the disturbance of current device, let the filler flow from opening department, flow to certain volume time, shore 2 this moment will be along the inner wall downstream of last connecting cylinder 11, and then realize shore 21 and the template separation of 2 top settings of shore, after the support that supports this piece template all left, it can to take off the template, just so avoided because the mould removal of forcing, to the damage of cast-in-place case roof beam bottom surface, influence the quality of engineering. When this support can conveniently dismantle, from the top down goes on, reduces the damage to bridge box girder concrete to this support simple structure, the material is easy, and the cost is cheap, can reuse many times, practices thrift the cost.
