As the embodiment bis-of the utility model cement induration, as shown in Figures 4 to 6, be to be equipped with loaded plate 15 on described left half cylindrical shell 11 and right half cylindrical shell 12 with embodiment mono-difference, the plane at described loaded plate 15 places and the axis of cylindrical shell 1 are perpendicular, and described loaded plate 15 is the anchored force with cement induration for increasing build-in member 10.The cross sectional area of described loaded plate 15 is greater than the cross sectional area of reinforcing bar 20, is less than the cross sectional area of anchor hole 30, and size can be selected arbitrarily according to actual needs, the shape of loaded plate 15 can be square, circular etc. various shapes.Top, middle part or the bottom that loaded plate 15 is located at left half cylindrical shell 11 and right half cylindrical shell 12 all can, be in general preferably located on the equal height position of left and right half cylindrical shell, so that form a plane after amalgamation.
In the present embodiment, between described cylindrical shell 1 and loaded plate 15, be provided with diagonal rib 16, described diagonal rib 16 can improve the intensity of loaded plate 15, prevents that loaded plate 15 and cylindrical shell 1 from rupturing; In addition, described left half cylindrical shell 11 and right half cylindrical shell 12 are equipped with the diagonal rib 16 cooperatively interacting in mosaic, and described diagonal rib 16 is provided with the first through hole 161, utilize bolt 2 through described the first through hole 161, left half cylindrical shell 11 to be connected with right half cylindrical shell 12.Certainly it is also feasible utilizing pin or rope through described the first through hole, left half cylindrical shell to be connected with right half cylindrical shell.
In the present embodiment, on described loaded plate 15, be also provided with the breach 151 passing for Grouting Pipe, Grouting Pipe, anchor rod body (reinforcing bar 20) are relative with build-in member 10 is sent to 30 li of anchor holes after fixing together, then by Grouting Pipe to the interior cement injection of anchor hole 30, described breach 151 also can replace with third through-hole, can make equally Grouting Pipe pass, can obtain essentially identical beneficial effect.
As the embodiment tri-of the utility model cement induration; as shown in Figure 7 to 9; be to be equipped with centring ring 14 on described left half cylindrical shell 11 and right half cylindrical shell 12 with embodiment mono-difference; the diameter of described centring ring 14 is slightly less than anchor hole 30 diameters; can be to the comprehensive 360 degree positioning supports of reinforcing bar 20; reinforcing bar 20 is centered in anchor hole 30, and all directions can reach the requirement of the minimum cement paste protective layer thickness of designing requirement.
In the present embodiment, described left half cylindrical shell 11 and right half cylindrical shell 12 are equipped with lug 17 in mosaic, described lug 17 is provided with the second through hole 171, utilize bolt 2 through described the second through hole 171, left half cylindrical shell 11 to be connected with right half cylindrical shell 12, it is also feasible certainly utilizing pin or rope through described the second through hole, left half cylindrical shell to be connected with right half cylindrical shell.
In the utility model, described left half cylindrical shell and right half cylindrical shell are can also a side hinged, and opposite side is spirally connected by bolt or by being fixed; Or described left half cylindrical shell and right half cylindrical shell both sides are all spirally connected by bolt, or all by being fixed.As long as left half cylindrical shell is no longer separated with after right half cylindrical shell amalgamation.
As cement induration embodiment tetra-described in the utility model, as shown in figure 10, be that with embodiment bis-differences described cement induration 40 is reinforced concrete structural element, many reinforcing bars 20 are arranged in parallel, each reinforcing bar 20 is provided with build-in member 10, build-in member 10 can be any one of described build-in member above, and the intensity of described reinforced concrete structural element is higher, especially the intensity of reinforcing bar 20 length directions.In the present embodiment, multiple build-in members can also be integrally connected, and form a common stressed tabular component.
As cement induration embodiment five described in the utility model, as shown in figure 11, be that with embodiment tetra-differences described cement induration is reinforced concrete beam 40, reinforcing bar 20 two ends in reinforced concrete beam 40 are provided with build-in member 10, and build-in member 10 can be any one in described build-in member above.
The two ends of the reinforcing bar in prior art in reinforced concrete beam are anchoring section, for increasing anchored force, standard practice is to form crotch reinforcing bar bending two ends, this can cause the effective length of reinforcing bar to diminish, and causes waste, in the present embodiment, build-in member 10 is located at the termination of reinforcing bar 20, for replacing anchoring section and the crotch at prior art reinforcing bar two ends, thereby save amount of reinforcement, and improve the stress of steel concrete.
As cement induration embodiment six described in the utility model, as shown in Figures 12 and 13, be that with embodiment mono-difference described arc unit 18 quantity are three, described arc unit 18 is arranged with urceolus 4, described urceolus 4 is waled described arc unit 18, making 18 amalgamations of arc unit is cylindrical shell 1, between the each arc of the present embodiment unit 18, leaves space D.Generally, the inner surface of the external surface of arc unit 18 and urceolus 4 can be inclined-plane (5～10 ° of guide angles), like this urceolus 4 banding arc unit 18 better.Concrete assembly method is: first urceolus 4 covers are set on reinforcing bar 20, because the internal diameter of urceolus 4 is greater than the external diameter of reinforcing bar 20, so can freely slide on reinforcing bar 20, then 18 installation site, the three arc unit reinforcing bar 20 of filling the span of a man's arms, form cylindrical shell, again, urceolus 4 is set in to the outside compression of arc unit 18, thereby urceolus 4 and arc unit 18 are all fixed, assembly method is simply efficient.When amalgamation, three arc unit 18 can be close to a complete cylindrical shell of formation between two, between three arc unit 18, also can leave spacing and amalgamation is an incomplete cylindrical shell, as long as the rib line of arc unit 18 inner surfaces and the rib line interlock of reinforcing bar 20 just can fixations and born weight.On urceolus 4, be also provided with loaded plate 15 in addition, the plane at described loaded plate 15 places and the axis of cylindrical shell 1 are perpendicular, between urceolus 4 and loaded plate 15, are provided with diagonal rib 16.
Certainly, centring ring also can be set, to form locator on described urceolus.In the present embodiment, arc element number can be also two or four, can reach essentially identical effect, repeats no more herein.
As cement induration embodiment seven described in the utility model, as shown in FIG. 14 and 15, be that with embodiment six differences described loaded plate 15 is arranged on arc unit 18, between arc unit 18 and loaded plate 15, be provided with diagonal rib 16, other structure is all consistent with embodiment six with beneficial effect.In the present embodiment, can on each arc unit 18, loaded plate 15 be all set, also can only on one or two arc unit 18, loaded plate 15 be set.
In the present embodiment, centring ring also can be set, to form locator on described arc unit.
In above embodiment, can same direction setting between build-in member, also can arrange in opposite directions, specifically determine in the stress at each position according to reinforcing bar.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
