Description
Technical field
The utility model relates to a kind of combination spike, belongs to building material field.
Background technology
Due to the using function variation of modern architecture, in cast-in-place structural plate, the use of double-layer double-direction steel mesh reinforcement is very extensive.Most often a few font steel bar horse-shaped benchs provided in " building operations handbook " are provided in current engineering.On a few font steel bar horse-shaped bench, horizontal reinforcement colligation is between lower row's muscle of top mat, the load of top mat reaches on the spacer bottom a few font steel bar horse-shaped bench by two sections of vertical lengths of rebar of a few font steel bar horse-shaped bench, spacer and a few font steel bar horse-shaped bench form support structure on underlay, to ensure that distance between upper and lower layer steel mesh reinforcement is in scope of design.But also there is following problem in a few font steel bar horse-shaped bench in implementation process: a few font steel bar horse-shaped bench stress point branch arranges on muscle under two of top mat, trampled rear because of two reinforcing steel bar bears uneven, easily cause a few font steel bar horse-shaped bench off normal to topple over; Mounted a few font steel bar horse-shaped bench, because of many with structural slab reinforcing bar binding tie point, easily loosen in work progress, is shifted, cause levels reinforcing bar apart from less than normal; Top reinforcement row's muscle off the net, the flexural deformation because of concentrated pressurized; A few font steel bar horse-shaped bench adopts bar bending to make, and bar material waste is larger; A few font steel bar horse-shaped bench need use thin wire and top mat colligation, and base plate need pad establishes two pieces of spacers, installs loaded down with trivial details; Spacer is easily shifted, and affects thickness of protection tier.
Utility model content
The purpose of this utility model is: provide a kind of combination spike, to solve existing a few font split heads because of poor stability, affect the problem of top mat topping; Easily be shifted to solve existing spacer, affect the problem of lower floor's steel mesh reinforcement topping; To solve the problem that prior art effectively cannot control Bars In Poured Concrete Slab thickness; The deficiencies in the prior art can be overcome.
The technical solution of the utility model
A kind of combination spike, comprise concrete knoll, be provided with cross groove one at concrete knoll top, be provided with cross groove two bottom concrete knoll, concrete protective cushion block is placed in cross groove two.
In aforesaid combination spike, column or the square structure of described concrete knoll to be vertical section be " convex " shape, in the middle part of concrete knoll, arrange waterstop, this structure makes concrete knoll can place stable and make to have water stopping function.
In aforesaid combination spike, the cross section of described cross groove one and cross groove two is inverted cone shape structure, and this structure makes the insertion of reinforcing bar and places can be more convenient.
In aforesaid combination spike, the actual Bars In Poured Concrete Slab consistency of thickness of the height of described concrete knoll and scene.
In aforesaid combination spike, the degree of depth=top mat thickness+top mat protection thickness of described cross groove one, the bottom width 2 ~ 10mm larger than the thickness of the lower placing of reinforcement of top mat of cross groove one.
In aforesaid combination spike; the degree of depth=lower floor's steel mesh reinforcement thickness+lower floor steel mesh reinforcement protection thickness+(5 ~ 10) mm of described cross groove two; bottom width 2 ~ the 10mm larger than the diameter of the upper placing of reinforcement of lower floor steel mesh reinforcement of cross groove two; by arranging surplus; can guarantee that cross recess two can be filled full by concrete; thus ensure that reinforcing steel bar bear is even.
In aforesaid combination spike, the thickness of concrete protective cushion block protects thickness consistent with lower floor steel mesh reinforcement.
Owing to have employed technique scheme, compared with prior art, support structure on the utility model adopt combination spike instead of underlay that existing spacer and a few font steel bar horse-shaped bench form, because combination spike is concrete element, save the reinforcing bar of the existing a few font steel bar horse-shaped bench of making, reduce the cost of manufacture of steel mesh reinforcement, fix without the need to colligation when concrete knoll is installed, install very convenient, because combination spike height equals thickness of slab, Bars In Poured Concrete Slab concrete is directly built to concrete knoll end face absolute altitude, compensate for the defect of the uncontrollable Bars In Poured Concrete Slab thickness of slab of existing a few font steel bar horse-shaped bench, concrete protective soil layer cushion block is positioned in concrete knoll cross groove two, concrete pier is directly placed in template, to solve on current concrete protective soil layer cushion block and a few font steel bar horse-shaped bench underlay in support structure, the problem of the easy displacement of concrete protective soil layer cushion block, because concrete knoll is up-small and down-big, can not topple over because of rocking of top mat, because concrete knoll is prefabrication, strictly can control its top cross groove degree of depth, solve in reinforcing bar rectification process because top mat disturbance causes a few font steel bar horse-shaped bench off normal, and affect the problem of top mat protective layer thickness, because combination spike can be prefabricated at factory's batch, greatly save the time of the existing a few font steel bar horse-shaped bench of field fabrication.
