Description
Technical field
When the utility model belongs to concrete pavement construction, longitudinal joint arranges pull bar field, particularly relates to a kind of pull bar locating support.
Background technology
At present, national highway Engineering Cement Concrete Pavement construction technique normalizing specifies, the pull bar fixing means in the longitudinal joint of rigid pavement has three kinds: 1, apertured in template, penetrated in hole by pull bar after formwork erection before concreting; 2, pull bar is bent to right angle, after formwork erection, the half of pull bar is tied up in template, second half is cast in concrete, by directly curved for side reinforcing bar after form removal; 3, adopt the pull bar of strap bolt, the pull bar support of a half band screw is fixed in basic unit, and after form removal, the pull bar of second half strap bolt joint is connected with the half root pull bar be embedded in concreting;
Found by a large amount of practices, there is corresponding problem respectively in these three kinds of methods: one, in the 1st kind of method, pull bar is penetrated after in hole, 1), first concreting the position of pull bar is bad fixing, needs to send 1 to 2 professional to place and steady brace in practice of construction, and the placement of pull bar and fixing means have following several:, with hammer, pull bar is squeezed into afterwards, during vibrated concrete, pull bar can be dilapidated, and position changes; 2), in the process of vibrating pull bar is squeezed into, and can not loose one's grip in the process of vibrating, can ensure that the position of pull bar is accurate, but very disabled person's work; 3), vibrate after squeeze into pull bar again, this method, pull bar and concrete are in conjunction with insecure, and form removal back stay is easily extracted loss by people, do not lose because also not having the due effect of pull bar in conjunction with insecure; Two, in the 2nd kind of method, practical operation is very difficult, if use this method, needs first in template, to determine spacing, center, and, with once, measure once, pretty troublesome; Three, in the 3rd kind of method, to the processed complex of reinforcing bar own, cost is high, and need again the cost of materials, moulding expense, the fixed charge that increase support, a lot of unit in charge of construction can not accept; Even if adopt reluctantly, by the impact of ground height change, the height of fixed mount cannot frequent variations, and the pull bar after fixing is difficult to keep balance.
In a word, existing pull bar fixing means, no matter be the method that national regulation specifies or other method adopted in constructing, all exist and fix loosely, center controls inaccurate, and equilbrium position controls inaccurate, and reinforcing bar is combined loosely with concrete, waste is a large amount of artificial, really cannot realize original intention and the object of pull bar design.
Summary of the invention

Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As Figure 1-4, a kind of pull bar locating support, its slide block device 2, scale fixed mount 3, integrated support frame 4 of mainly comprising angle bar 1 and being arranged on angle bar 1, the vertical sidewall of angle bar 1 is provided with some slide block devices 2 along its length, two ends, angle bar left and right are respectively arranged with a scale fixed mount 3, the angle bar between two scale fixed mounts 3 are also provided with two integrated support framves; Described slide block device 2 is made up of top board 6, L shape side plate 5 and pipe 7, top board 6 is connected on the upper side edge of side plate 5, the soffit of top board 6 is connected on the upper side edge of the vertical sidewall of angle bar 1, and angle bar is positioned at the notch surrounded by top board and side plate, described pipe 7 is welded on the soffit of top board, and the mouth of pipe of pipe 7 one end is just to the vertical sidewall of angle bar 1, the vertical sidewall of described side plate 5 is connected with a bolt 8, the end of bolt 8 withstands on the vertical sidewall of angle bar 1; Described scale fixed mount 3 comprises L shape fixed head 9 and eye bolt 10, the head of eye bolt 10 radially offers through hole, the dual-side rear formation of corresponding welding one section of box section A respectively of fixed head 9 and angle bar 1, eye bolt 10 is from top to bottom through this box section A, and the screw rod of eye bolt is fitted with butterfly nut 11, in the through hole of eye bolt head, be provided with scale bar 12; Described integrated support frame 4 device comprises L shape gripper shoe 13, the dual-side rear formation of corresponding welding one section of box section B respectively of gripper shoe 13 and angle bar 1, the upper surface of this box section B offers the square through hole running through its upper and lower end face, a square tube 14 is equipped with in square through hole, the bottom of square tube is provided with U-shaped supporting leg 15, a sidewall of described box section B is equipped with manual jackscrew 16, and the end of manual jackscrew withstands on the sidewall of square tube.
Concrete using method of the present utility model is: when rigid pavement engineering construction, after vertical good template, needing the side of installing pull bar, laying described pull bar locating rack, fixing vertical with angle bar 1 for scale bar 90-degree rotation.First in the pipe of pull bar locating rack two ends He in corresponding templates hole, respectively put a pull bar, pull bar outer end to penetrate in pipe on slide block device 27 and holds out against angle bar 1, two scale bar 12 is held out against template, after meeting the protruded length of pull bar needs according to the length of designing requirement adjustment scale bar 12, tighten butterfly nut 11; According to clearance between tiebars design data, adjustment slide block device 2 position, the corresponding pattern hole of each slide block device 2, tights a bolt after aligning and fixes slide block device 2, penetrates a pull bar in the pipe 7 on the slide block device 2 of each pattern hole and correspondence, pull rod pressing angle bar 1, check the horizontal plane situation of pull bar, as undesirable, the position that the manual jackscrew 16 of adjustable withstands in square tube 14 adjusts, until meet the level requirement of pull bar, then tighten manual jackscrew 16.This way is that pull bar is first located after-pouring concrete, and building and vibrating in process, pull bar all can not conjugate, once end of vibrating, just can remove pull bar locating support, moves forward and carries out the fixing of lower a set of pull bar.As programming is very fast, when a set of pull bar locating support is not enough, a few cover can be prepared more, hocket.So both can ensure programming, can ensure that again draw rod positions is fixing accurately, combine firmly, after concrete setting, anyone can not free-handly extract, and the phenomenon effectively prevented loss occurs.This method uses simple, and convenient, efficiency is high, reliable in quality.
