The present invention lacks the convenient pre-applied opening devices of installation and removal to solve the prior art, can not balancing run convenience Contradiction between shearing strength, grouting process provides a kind of device for being used to form expanding pre-manufactured hole, as shown in Figure 1 and Figure 2, Including device for spreading, resilient sleeve 40, drive rod, drive rod is connect with device for spreading, and resilient sleeve 40 is set in outside device for spreading;Pressure Enter drive rod, device for spreading is strutted with drive rod linkage, strutted outward from middle position by resilient sleeve 40;Extract drive rod, support out Opening apparatus and drive rod linkage are shunk, and resilient sleeve 40 resets.To the prefabricated hole site before prefabricated components casting concrete in component Installation device of the present invention is set, after hardening, device for spreading shrinks demoulding, can be easily from the prefabricated components conserved It takes out, produces expanding pre-manufactured hole, the switching performance between later period grouting material and hole wall can be reinforced, increase grouting material and pre-manufactured hole Between mechanical snap power and pre- slurrying anchor component connection after shear behavior and anchoring property.
In the present invention, device for spreading includes several spreading mechanisms 10 around drive rod, can preset to obtain section to be diamond shape Pre-manufactured hole.As shown in Figure 1, spreading mechanism 10 includes fixed arm 11, travelling arm 13, transmission arm 14, actuating arm 15, fixed arm 11 Upper end rotational positioning, upper end and the fixed arm 11 of travelling arm 13 be slidably connected, and the lower end of travelling arm 13 is upper with transmission arm 14 End rotation connection, the lower end rotational positioning of transmission arm 14;The inner end of actuating arm 15 and drive rod are rotatablely connected, outside actuating arm 15 End is rotatablely connected with transmission arm 14.Sliding slot 12 is offered on fixed arm 11, the upper end of travelling arm 13 is symmetrical double grip-pieces, double fastener Piece is installed in the two sides of sliding slot 12, and pivot pin is connected between double grip-pieces, and pivot pin is threaded through in sliding slot 12.
The present invention is provided with bottom plate 30, as shown in figure 3, for spreading mechanism 10, resilient sleeve 40 to be arranged at bottom plate 30 On, rotational positioning is carried out to transmission arm 14 by bottom plate 30, positioning when drive rod is oriented to and is pressed into.
Spreading mechanism 10 is evenly arranged on the upper surface of bottom plate 30, so that the diamond shape pre-manufactured hole of regular shape is made.Transmission arm 14 Lower end and bottom plate 30 connecting plate 34 be rotatablely connected, to entire spreading mechanism 10 provide support force.In the present embodiment, machine is strutted Structure 10 is arranged in pairs, then multipair spreading mechanism 10 can be arranged according to actual needs, is commonly used for 2,3,4 pairs of setting.
Drive rod is arranged in the through-hole 35 of bottom plate 30, specifically, drive rod includes guide rod 21, handle 22, guide rod 21 is cut Face can be round or rectangular or other regular shapes.Guide rod 21 is threaded through on bottom plate 30, the top of guide rod 21 and struts machine The upper end of the fixed arm 11 of structure 10 is rotatablely connected, and the bottom end of guide rod 21 is arranged in handle 22, positioned at the lower surface side of bottom plate 30. Drive rod further includes top plate 23, as shown in figure 4, the top of guide rod 21 is fixed on top plate 23.Guide rod 21 is provided with to be prolonged around The driving plate 25 stretched, the inner end of the actuating arm 15 of spreading mechanism 10 and driving plate 25 are rotatablely connected.
Top plate 23 extends the fixed plate 24 of the fixed link of corresponding spreading mechanism 10 around, the upper end of fixed arm 11 and solid Fixed board 24 is rotatablely connected, and provides resistance for entire spreading mechanism 10, then entire spreading mechanism 10 top plate 23 and bottom plate 30 it Between strutted and shunk.
In order to make the present invention that can stably keep indentation state after the indentation of guide rod 21, guide rod 21 is in 30 lower surface one of bottom plate Side is provided with rotation snap-gauge 26, and snap-gauge 26 can make 360 ° of rotations around guide rod 21, and the upper and lower sides of rotation snap-gauge 26 are provided with card mat 27, rotation snap-gauge 26 is positioned;The lower surface of bottom plate 30 is provided with card slot 31.When operation, it is pressed into guide rod 21, rotates snap-gauge 26 enter in card slot 31 from the opening of card slot 31, rotary motion snap-gauge 26, and are installed in card slot 31.In the present embodiment, card slot 31 include " L " the type fixture block 32 being symmetrically oppositely arranged, and the interval between " L " type fixture block 32 is wider than the width of rotation snap-gauge 26, small In the length of rotation snap-gauge 26.And then rotating snap-gauge 26 has enough spaces to enter inside card slot 31, when needing to extract out guide rod 21 When, it is only necessary to rotation snap-gauge 26 is rotated 90 ° from detent position, rotation snap-gauge 26 can be deviate from from the opening of card slot 31, keep away Exempt from guide rod 21 to need to rotate multi-angle and cause excessively to pull the actuating arm 15 of device for spreading and damage.
The upper surface of bottom plate 30 is additionally provided with connection ring 33, and the opening of resilient sleeve 40 is connect with connection ring 33.
The present invention is being installed in the pre-manufactured hole position of component to before prefabricated components casting concrete, and is being contacted with concrete Interface be brushed on release agent, facilitate the dismounting that concrete hardening is later.The casting concrete into prefabricated components, and conserve at After type, the rotary motion snap-gauge 26 from card slot 31 catches handle 22 to extract guide rod 21 outward out, device for spreading natural shrinking, i.e., The present invention can be extracted.
When needing to change the shape or slope of preset hole, the length of fixed arm 11 and sliding slot 12 is determined using graphing method Degree, with the efficiency needed.As shown in figure 5, using the rotating fulcrum of driving plate 25 as initial point A, with the length of the indentation of guide rod 21 Degree S can determine A1 point, F1 point.Using A1 point as the center of circle, the length r1 (centre distance of both ends rotating fulcrum) of actuating arm 15 is Radius draws circle C1.Using the rotating fulcrum center of the connecting plate 34 on bottom plate 30 as center of circle B point, half length of transmission arm 14 R2 (centre distance of central rotational fulcrum and the rotating fulcrum of lower end) is radius, draws circle C2.Using B point as the center of circle, transmission The total length r3 (centre distance of the rotating fulcrum of the rotating fulcrum and lower end of upper end) of arm 14 is radius, draws circle C3.Then Round C1 and C2 intersects at D point, connects BD two o'clock, and extended line and circle C3 intersect at E point.E point and F1 point are connected, it is acquired The difference of the length L2 and initial length L1 of EF1 are the shortest length that sliding slot 12 needs to slide.
Above-described embodiment is intended merely to illustrate the present invention, and is not used as limitation of the invention.As long as according to this hair Bright technical spirit is changed above-described embodiment, modification etc. will all be fallen in the scope of the claims of the invention.
