Description
Technical field
The utility model belongs to construction engineering technical field, and in particular to a kind of filling pile head steel reinforcement protective sleeve.
Background technique
Bored concrete pile has many advantages, such as that bearing capacity is high, construction technology is mature, low cost, is therefore widely used in industry and the people
With building, bridge basis in.During filling pile construction, since a part of concrete strength of topmost is poor, in order to
Guarantee monolithic concrete intensity, and avoid stake top absolute altitude not in place, often selection perfusion absolute altitude is more than stake top absolute altitude, then
Abolish extra part.
The common method of broken pile head is manually to be aided with small machine to cut or cut in the above position of designed elevation mixed at present
Solidifying protective soil layer, keep reinforcing bar exposed and remove concrete, be primarily present following shortcoming: 1) pile crown is abolished time-consuming and laborious, and
Manually, machinery expenses are high.
2) it when pile crown is abolished, will certainly affect to main reinforcement, construction quality is difficult to ensure.
Even if abolishing pile crown at existing patent of invention " bored concrete pile abolishes pile crown construction technology " (CN105735317A)
When, it is still necessary in the symmetrical perforating of position impact gun for abolishing pile crown.
Summary of the invention
The utility model aiming at the above problem, provide it is a kind of can protect pile crown reinforcing bar, and be easy to abolish pile crown
Filling pile head steel reinforcement protective sleeve.
In order to realize the above-mentioned purpose of the utility model, the utility model adopts the following technical solution, the utility model packet
Include protection sleeve pipe and split tube, it is characterised in that: protection sleeve pipe one end is opening, and split tube both ends are closing, protection sleeve pipe
It is connected by connector with split tube；Be provided with two orthogonal through-holes on the connector, the through-hole and split tube and
Protection sleeve pipe matches.
As a kind of preferred embodiment of the utility model, the connector surface is provided with two locking screws corresponding to two through hole
Hole.
As another preferred embodiment of the utility model, positioning plasma resistance sleeve is provided in the protection sleeve pipe.
As the third preferred embodiment of the utility model, positioning plasma resistance piece group is provided in the protection sleeve pipe.
The utility model has the beneficial effects that the utility model assembling is easy, is easy to use, solve concrete and pile crown steel
The problem of muscle bonds is avoided using level splitting hole pipe in the work for abolishing the horizontal perforating in pile crown position, to improve brokenly
Except the working efficiency of pile crown.
The utility model is easy to operate, easy to use, does not have to Special Training；Use scope is wide, and demand is larger, before market
Jing Hao.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model connector.
Fig. 3 is a kind of structural schematic diagram of embodiment of protective case.
Fig. 4 is the structural schematic diagram of protective case another kind embodiment.
Fig. 5 is the usage state diagram of the utility model.
In attached drawing 1 be split tube, 2 be connector, 3 be protection sleeve pipe, 4 be locking screw holes, 5 be through-hole, 6 be positioning plasma resistance
Sleeve, 7 are positioning plasma resistance piece group.
Specific embodiment
The utility model includes protection sleeve pipe 3 and split tube 1, it is characterised in that: 3 one end of protection sleeve pipe is opening, splitting
1 both ends of pipe are closing, and protection sleeve pipe 3 is connected by connector 2 with split tube 1；Two are provided on the connector 2 mutually to hang down
Straight through-hole 5, the through-hole 5 are matched with split tube 1 and protection sleeve pipe 3.
As a kind of preferred embodiment of the utility model, 2 surface of connector is provided with two lockings corresponding to two through hole 5
Screw hole 4.
As another preferred embodiment of the utility model, positioning plasma resistance sleeve 6 is provided in the protection sleeve pipe 3.It is fixed
Steric hindrance slurry sleeve 6 can be made of sponge or polyurethane foam, and outer diameter is identical as the internal diameter of protection sleeve pipe 3, and internal diameter compares pile crown
Small 3~the 5mm of bar diameter, protection sleeve pipe 3 and positioning plasma resistance sleeve 6 can be fixed by seccotine.To save material, plasma resistance is positioned
The ratio of the length of the length and protection sleeve pipe 3 of sleeve 6 can use 1:3 or 1:2.In use, protection sleeve pipe 3 is directly sleeved on stake
On head reinforcing bar, since positioning plasma resistance sleeve 6 is made of sponge or polyester form, elasticity can stablize protection sleeve pipe 3
Ground is fixed on pile crown reinforcing bar, while preventing it from shaking floating, cement slurry can be organized to enter in sleeve.
As the third preferred embodiment of the utility model, positioning plasma resistance piece group 7 is provided in the protection sleeve pipe 3.It is fixed
Steric hindrance lodicule group 7 is made of multiple positioning plasma resistance pieces, and the center bore for positioning plasma resistance piece is 2~3mm smaller than pile crown bar diameter,
It positions on the centre bore of plasma resistance piece in the cross notch for symmetrically cutting with 2~3mm length, pile crown steel reinforcement protective sleeve pipe 3 can be made
Smoothly cover on pile crown reinforcing bar.Protection sleeve pipe 3 can be firmly secured on pile crown reinforcing bar by its elasticity, prevent it from shaking
While floating, cement slurry can be organized to enter in sleeve.
The implementation process of the utility model: protection sleeve pipe 3, split tube 1, connector 2 are pressed the form group of Fig. 1 by step 1
Dress up one, quantity is at least 4 or more even numbers, and in cross or rice font or star-like symmetrically covers on pile crown reinforcing bar
(as shown in Figure 5), and carry out in stake week the telltale mark of 1 position of split tube.Note: exposing under connector 23 lower end of protection sleeve pipe
End length must not exceed 50mm, and it is identical as pile body protective layer thickness that 2 outboard end length of connector is exposed in 1 outer end of split tube.
Step 2, by 3 sets of protection sleeve pipe on remaining pile crown reinforcing bar.
Step 3 is completed pile concrete and is poured.
Step 4 slightly clears up concrete according to telltale mark, finds split tube 1, opens closed end, uses splitting
Tool cleaves pile crown concrete, then removes pile crown with hanging device.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality
Within novel protection scope.
