Abstract
The utility model relates to a kind of height-adjustable external prestressing steering block, belongs to Structural Engineering field.The utility model symmetry on the biside plate of U-board has at least one group of bolt mounting holes, and described U-board outer wall is provided with inverted U-channel, and the side plate of inverted U-channel and U-board is bolted fixing.The utility model symmetry on the biside plate of U-board has at least one group of bolt mounting holes, and outside the side plate by bolt inverted U-channel being fixed on U-board, realize the height adjustable of inverted U-channel in U-board, complete the external power muscle supporting of differing heights, inverted U-channel support bar effectively prevents the local fatigue in the structure of external power muscle, can reduce loss of prestress simultaneously, adequately achieve the advantage of steel plate materials, and construction is simple, feasibility is high.
Description
technical field:
The utility model relates to a kind of height-adjustable external prestressing steering block, belongs to Structural Engineering field.
background technology:
At present, the application of external prestressing in stabilization works is more and more extensive, wherein steering block occupies very important status in prestressed structure in vitro, and it not only plays fixing line style, and span centre prestressing effect is delivered on concrete component by steering block just.At present, the prestressing force steering block that external prestressing strengthening adopts realizes mainly through steady job intermediate plate, cannot realize secondary and utilize, can not realize the adjustment of different degree of prestressing lower body external force muscle support height after having reinforced to experimental facilities.
utility model content:
The purpose of this utility model is to provide a kind of height-adjustable external prestressing steering block, and this steering block solves adjustable for height problem, and harmless to beam, and simple structure, easy construction, easily dismantles.
technical solution:
The utility model comprises U-board, and on the biside plate of U-board, symmetry has at least one group of bolt mounting holes, and described U-board outer wall is provided with inverted U-channel, and the side plate of inverted U-channel and U-board is bolted fixing.
Support bar is provided with in described inverted U-channel.
Described U shape plate is formed or integral casting forming by two blocks of vertical steel plates and one piece of bottom panel weld.
The side plate of described inverted U-channel and U-board is connected and fixed by double bolt.
The utility model symmetry on the biside plate of U-board has at least one group of bolt mounting holes, and outside the side plate by bolt inverted U-channel being fixed on U-board, realize the height adjustable of inverted U-channel in U-board, complete the external power muscle supporting of differing heights, inverted U-channel support bar is welded by two semicircles, and support bar effectively can prevent the local fatigue in the structure of external power muscle, loss of prestress can be reduced simultaneously, adequately achieve the advantage of steel plate materials, and construction is simple, feasibility is high.
The hole of the vertical steel plate of the utility model U-board avoids support bar, and support bar is semicircle steel pipe, and preventing when mounted cannot erection bolt; The shape of falling U groove structure, the vertical steel plate in outside plays limiting plate, and medial shaft squeezes into four bolts hole to steel plate middle body, and pore size is identical with aperture, U-board vertical steel plate hole.
accompanying drawing illustrates:
Fig. 1 is the utility model front view;
Fig. 2 is the utility model lateral view.
detailed description of the invention:
Embodiment 1
The utility model U-board is by bottom panel 1 and two pieces of riser 2 vertical weldings, be sheathed on beam section, uniform five row's two routine bolt mounting holes on vertical steel plate 2, inverted U-channel is by two blocks of vertical steel plates 4 and one piece of end face steel plate 3 vertical welding, vertical steel plate 4 middle body has the bolt hole of four distributed rectangular, aperture is identical with the pore size that vertical steel plate 2 is opened, support bar in inverted U-channel is by top panel 3 and two semicircle steel pipe 6 vertical weldings, semicircle steel pipe 6 realizes radial transmission vertical load, vertical steel plate 2 is fixed with steel plate 4 bolt, realize the synergy of clamped beam and the external power muscle of supporting constraint.This utility model have effectively achieved supporting and the restriction of the external power muscle of differing heights.
Use procedure
Steering block has the linear function of fixed body external force muscle, according to the external power muscle height assembling steering block that the degree of prestressing calculated is corresponding, the bolt hole of two pieces of risers 2 of U-board aligns with the bolt hole of the vertical steel plate 4 of both sides inverted U-channel, be bolted fixing, can realize the assembling of steering block, pulling test is carried out in the position of fixed body external force muscle.Different degree of prestressing correspond to the height of different external power muscle, are removed by bolt 5, two inverted U-channel height up and down, and connect with bolt, can realize the adjustment that external power muscle corresponding to different degree of prestressing is linear.
For increasing intensity of the present utility model, U-board adopts monoblock cast to form.
Claims (4)
1. a height-adjustable external prestressing steering block, comprise U-board, it is characterized in that, on the biside plate of U-board, symmetry has at least one group of bolt mounting holes, described U-board outer wall is provided with inverted U-channel, and the side plate of inverted U-channel and U-board is bolted fixing.
