Description
Technical field
The present invention relates to reinforced concrete protective layer positioner technical field.
Background technology
The concrete component generally used in building is mixed in a certain ratio by cement, sandstone material and water as having
Liquid-plastic state, and by template be fixed to need geometry size and after hydrated cementitious formed have people need intensity
Concrete material primary structure member.When the outer reinforcement in reinforced concrete skeleton is more closely from armored concrete edge
When thickness of concrete cover is inadequate, reinforced concrete member produces crackle of creeping, air under temperature change and stress effect
In oxygen will reduce the active strength of reinforced concrete structure by hair check oxidation corrosion reinforcing bar, make armored concrete knot
Structure bearing capacity, which reduces, to be caused the engineering lost of life or cannot normally play item-function before the deadline, serious also to collapse suddenly
Collapse the accidents such as destruction, jeopardize the safety of life and property of people；And when concrete cover is blocked up, reinforced concrete member ruler
It is very little to need increasing to meet force request, it is uneconomical.For this reason, in all kinds of design of reinforced concrete structure and construction inspection rules
The thickness of protection tier of reinforced concrete structure is specify that, to ensure the quality of reinforced concrete structure and quality life-span week
Phase.The mortar that is generally used in current construction industry, concrete, plastics, ironware, ironcasting cushion block all cannot effective spacer bar positions
Put, can not ensure the accurate of thickness of concrete cover.
The content of the invention
Present invention aim to address problem existing in the prior art and defect, there is provided one kind is easy to make, installation is simple,
Firmly, it can accurately control the thickness of concrete cover of reinforced concrete member, improve reinforced concrete structure total quality
With the reinforced concrete protective layer locator of function.
The purpose of the present invention is achieved through the following technical solutions：
Reinforced concrete protective layer locator, including the integral type structure being welded to form by concentric screw rod and special-shaped termination
Part, the cannulated sleeve being sleeved on screw rod, the location nut being arranged between cannulated sleeve inner face and special-shaped termination and cushion cover；
The abnormal shape termination and the medial segment of screw rod welding are solid cylinder of the diameter more than screw rod, and segmentum laterale is that hollow circular cylinder is cut
The section formed after flat upper and lower surface is hollow cydariform and the oblate cylinder of up/down perforation, between medial segment and segmentum laterale
Stage casing is necking down changeover portion, and the outer end of necking down changeover portion is with diameter and the wide half slot of oblate cylinder up/down perforation mouth；Institute
Cannulated sleeve is stated as outer end opening, the inner sleeve bottom of with, the Inner discs at sleeve bottom are assembled with screw rod by thread fitting, hollow
The endoporus aperture of sleeve is more than the outside diameter of screw rod；The block that section is cydariform is fitted with the segmentum laterale inner cavity of special-shaped termination to lead
Column, the inner face of block guide post carry the guide post half slot wide with oblate cylinder up/down perforation mouth.
The present invention is provided with from outer end sleeve between screw rod and cannulated sleeve and length is more than hole length in cannulated sleeve
Cylindricality cushion block, the center hub of cylindricality cushion block is more than the blind hole of outer screw diameter for diameter.The section foreign steamer of the cannulated sleeve
Profile surface is octagonal cylinder or hexagon cylinder or cylindrical surface.Being made above screw rod has recessed groove and is carved with recessed groove
Graduated scale.In cannulated sleeve nozzle and cylindricality cushion block periphery, mutually equipped card slot and convex block are set.
, will by the special-shaped termination sleeve of the present invention on reinforcing bar when the present invention is used for reinforced concrete protective layer positioning
Reinforcing bar is clamped between the half slot of special-shaped termination necking down changeover portion and the guide post half slot of block guide post, by cannulated sleeve position
Rear locking positioning nut is adjusted, the distance between the outer end face of sleeve and the outer end face of abnormal shape termination are reinforced concrete floor
Thickness, by reinforced concrete floor both sides template clamp the present invention two end faces, be clamped in special-shaped termination necking down transition
Reinforcement location between section and block guide post is fixed, and will not be moved.It can ensure that after casting concrete, the concrete of reinforcing bar
Protective layer thickness is consistent with design requirement, so as to ensure construction quality.
Stabilized structure of the present invention is reliable, easy to install, can accurately control the concrete of reinforced concrete member to protect
Covering thickness, improves reinforced concrete structure total quality and function.

Embodiment
As shown in Figure 1 to 4, reinforced concrete protective layer locator of the invention is included by concentric screw rod 1 and different
One-piece member that type termination is welded to form, the cannulated sleeve 3 being sleeved on screw rod, be arranged at cannulated sleeve inner face with it is special-shaped
Location nut 4 and cushion cover 7 between termination.As shown in Fig. 5 a, Fig. 5 b, Fig. 5 c, the abnormal shape termination and the inner side of screw rod welding
Section 2a is the solid cylinder that diameter is more than screw rod, and segmentum laterale 2c is that hollow circular cylinder scabbles the section formed after upper and lower surface and is
The oblate cylinder of hollow cydariform and up/down perforation, the stage casing 2b between medial segment and segmentum laterale are necking down changeover portion, necking down
The outer end of changeover portion is with diameter and half slot 2b-1 wide oblate cylinder up/down perforation mouth 2c-1.The cannulated sleeve 3 is
Outer end is open, sleeve of the inner bottom of with, and Inner discs and the screw rod 1 at sleeve bottom are assembled by thread fitting, the endoporus of cannulated sleeve
Aperture is more than the outside diameter of screw rod.It is equipped with the segmentum laterale inner cavity of special-shaped termination just like shown in Fig. 6 a, Fig. 6 b, Fig. 6 c, Fig. 6 d
