Description
Technical field
The present invention relates to building construction technology.
Background technology
In building structure construction, underground garage ramp is ramp, and basement roof is the situation of inclined member, generally will
Directly branch is located at the load that transmission support top superstructure beam slab is transmitted on swash plate to support system.Support system on common swash plate
The construction way for installing is simple, or just without way, direct vertical rod branch is located on top board.Problem well imagines mainly have：
First, directly branch is located at the vertical rod on swash plate, and producing concentrated force to swash plate, and backing plate cannot be simply provided carries out accepting diffusion, right
Not up to the concrete of design strength produces flush shear force, causes swash plate surface layer to destroy；2nd, vertical rod eccentric force, frangibility and change
Shape, local stability is not enough, can sink after the formwork system stress of part, and floor flatness is uneven；3rd, vertical rod and swash plate contact surface
Stiction with vertical rod stress increase and increase, when stiction increases to maximum static friction force, formwork system produce cunning
Move, and then will overall collapse, cause security incident.
In view of the Construction quality and safety problem that causes of three class Mechanics Causes for existing, design more than one kind can solve
Setting up for support system constructs and its construction method on three kinds of concrete inclined members of the quality security problem of generally existing, just
Problem as professional's urgent need to resolve.
The content of the invention
The technical problems to be solved by the invention are just to provide support system on a kind of concrete inclined member, solve swash plate
The problem of swash plate punching failure, vertical rod local buckling and mould bases overall collapse during formwork.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：Supporter on a kind of concrete inclined member
System, rides upon on completed armored concrete inclined member, including along some of the domatic setting of armored concrete inclined member
Level concrete step, the armored concrete inclined member is domatic to be provided with the shearing resistance indent for being poured with concrete step and being integrated
With vertical joint bar, elongated I-steel is laid on the concrete step, support frame, the support of support frame are set up above I-steel
Vertical rod is supported on I-steel.
Preferably, the armored concrete inclined member is domatic to be provided with the dabbing being combined together with concrete step
Face.
Entirety is formed preferably, being used with the I-steel on one-level concrete step and linking bar connecting.
Preferably, the I-steel edge of a wing center weldment bar dowel, supported rod erecting is inserted on bar dowel.
Preferably, the concrete step correspondence I-steel position is embedded with supporting steel plate, set on the supporting steel plate
There is spacer bar, the I-steel is provided with the location hole plugged together with spacer bar.
Present invention also offers a kind of construction method of support system on concrete inclined member, comprise the following steps：Step
Rapid one：Concrete step is designed on armored concrete inclined member section, and determines every grade of concrete step highly, walkthrough branch
Support, it is determined that often arranging support frame vertical rod vertically and horizontally spacing；
Step 2：The swash plate reinforcing bar of assembling reinforcement concrete inclined member, and pre-buried vertical joint bar, vertical joint bar use with
The mode of the face reinforcement welding of armored concrete inclined member；
Step 3：Colligation section is the template of 80mm × 15mm as template at shearing resistance indent on the reinforcing bar of face；
Step 4：Pouring reinforcement concrete inclined member, after reaching people's intensity, digs out template at shearing resistance indent, opposite
Layer carries out the work of dabbing and cleaning, it is ensured that has at contact surface and is engaged enough；
Step 5：Formwork and casting concrete step；
Step 6：The line of I-steel is ejected on concrete step, while I-steel edge of a wing center weldment bar dowel；
Step 7：I-steel to correct position is put, along elongated I-steel length direction, is spaced a distance with linking steel
Muscle couples together I-steel；
Step 7：Foundation《Construction fastener type steel pipe scaffold technical specification of security》With《Building construction formwork safety
Technical specification》Support frame is set up, the supported rod erecting of support frame is supported on I-steel；
Step 8：After the completion of Superstructure Construction, support frame is removed, cut concrete step.
The technical solution adopted by the present invention, by setting concrete step and increasing I-steel, by the concentrated force of support frame
Even distributed force is converted into, the destruction to top board surface layer, and vertical rod section uniform force is eliminated, perpendicularity can guarantee that, enhance bar
The local stability of part；Simultaneously step and inclined member junction be provided with shearing resistance indent, contact surface dabbing treatment, bar dowel and
The ways such as reinforcing bar are linked, the bonding strength of contact surface is improve, the monolithic stability of support frame is improve.It is substituted for for steel pipe perpendicular
To heavy steel member support system, it may have larger bearing capacity, therefore on concrete inclined member, support system is set up
Construction and its construction method, with universal applicability, all have to improving floor slab construction quality and reducing construction safety hidden danger
Very real reference significance.
