Reserve in square hole 3 and hole is all arranges pre-buried steel sleeve pipe 5 at cylinder, steel sleeve one end is connected with embedded bar 6, one end perforate, and aperture is 1.5 times of the straight muscle of reinforcing bar, and it is identical that the degree of depth and bracket stretch out reinforcing bar length.In reserved square hole, pre-buried steel sleeve pipe 5 perforate end is concordant with hole inwall, and hole week pre-buried steel sleeve pipe 5 perforate end is concordant with the external wall of prefabricated post.
On prefabricated cylinder 1 and prefabricated bracket 2 interface, the steel plate perforate of respective pre-buried square opening steel plate 7,8, two is identical with corresponding reserved square hole size, i.e. the little 20mm of cylinder pre-embedded steel slab 7 perforate side ratio bracket pre-embedded steel slab 8 length of side; Bracket pre-embedded steel slab 8 is identical with bracket cross section, butt end size, and cylinder pre-embedded steel slab 7 to be grown up 20mm than bracket pre-embedded steel slab 7 neighboring.When bracket is installed, the setting that this two steel plates vary in size, can quickly and easily along the surrounding of bracket pre-embedded steel slab 8 and hole week by two Plate Weldings, play carrying effect.Two steel plates all arrange in steel sleeve position and punch, and cylinder pre-embedded steel slab punches and supplies cylinder pre-buried steel sleeve pipe 5 to pass, and bracket pre-embedded steel slab punches and supplies bracket reinforcing bar to pass.
At bracket pre-embedded steel slab 8 bottom uniform welding three pieces of steel floors 9, be embedded in bracket together with pre-embedded steel slab, effectively can improve the anti-pressure ability of bracket bottom, thus improve bracket bearing capacity.
The reinforcing bar that bracket reserves square hole 4 periphery bracket reinforcing cage 10 punches through pre-embedded steel slab and stretches out, when prefabricated bracket 2 is installed, Chemical Felter is injected in all pre-buried steel sleeve pipes in cylinder hole, then the reinforcing bar of bracket reinforcing cage 10 is inserted respective steel sleeve pipe, to be bonded dose solidify after, in the reinforcing bar of bracket reinforcing cage 10 and prefabricated cylinder, embedded bar 6 is together with bearing load.
Bracket is reserved square hole reinforcing cage 11 and is completed colligation in advance, when prefabricated bracket 2 is installed, Chemical Felter is injected in preformed hole pre-buried steel sleeve pipe 5, then reinforcing cage reinforcing bar is inserted respective steel sleeve pipe, to be bonded dose solidify after, build cylinder and bracket reserves square hole 3,4, the core concrete of formation can improve bracket shear resistance effectively.
The construction method of separate type prefabricated reinforced concrete bracket column, step is as follows:
Step 1: colligation cylinder reinforcing cage 12, bracket reinforcing cage 10 and bracket reserve square hole reinforcing cage 11 respectively, is connected pre-buried steel sleeve pipe 5 one end with cylinder embedded bar 6, and is fixed on cylinder reinforcing cage relevant position; Pre-embedded steel slab is fixed respectively at cylinder and bracket reinforcing cage relevant position.
Step 2: carry out the installation of cylinder template and bracket template, fixing, adjustment.
Step 3: respectively cylinder reinforcing cage 12 and bracket reinforcing cage 10 handling are entered mould, enter the reinforcing cage after mould in place by designing requirement, levelling.
Step 4: concreting, carries out maintenance.Form removal after reaching form removal condition also continues maintenance.
Step 5: during construction, first by prefabricated cylinder press-in relevant position, underground.
Step 6: after soil layer excavation to be done, cylinder is reserved square hole and pre-embedded steel slab is cleaned out, Chemical Felter is injected in cylinder service sleeve, the reinforcing bar of bracket reinforcing cage 10 is inserted the pre-buried steel sleeve pipe 5 in corresponding cylinder preformed hole week, reinforcing bar bracket being reserved square hole reinforcing cage 11 inserts cylinder and reserves pre-buried steel sleeve pipe 5 in square hole.
Step 7: to be bonded dose solidify after, build cylinder and bracket reserves square hole and maintenance, complete the construction of whole bracket column.
