Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the present invention are further illustrated:
As shown in Figure 1, Figure 3, a kind of pillar anti-faulting of slab ends construction method, the method is to water index bed side column and corner post about whole Shuttering supporting reinforce construction method, for side column use U-bend reinforcing bar 2 reinforce, for corner post use U-shaped angle Moment reinforcement 7 is reinforced, and concrete grammar is as follows:
1) at the pillar line of ink marker of acceptance(check), reserve the thickness of template 1, batten 3 is fixed on flooring formation One trogue, at the internal shuttering 1 of trogue, closes and reinforcing template 1;
Batten 3 nail is followed closely on flooring, and during construction side column, trogue has an open side, outside opening side blow, for side column Unsettled side;During construction corner post, trogue has two open side (adjacent), outside the two open side is rushed the most respectively, for two of corner post Unsettled side.
After pillar reinforcing bar binding acceptance(check), in the internal shuttering 1 of trogue, template 1 edge joint position is it is noted that align and connect Connect firmly.After post template 1 is normally closed and reinforced, the U-bend reinforcing bar 2 after bending machining or U-shaped angle are bent Reinforcing bar 7 is enclosed within bottom pillar outside template 1.
2) use U-bend reinforcing bar 2 when reinforcing side column, U-bend reinforcing bar 2 is inserted in from the unsettled side of side column, is enclosed within mould The bottom of plate 1, and pad and be placed on batten 3, then firmly stretching U-bend reinforcing bar 2, by the template 1 of unsettled for side column side tightly Fix, by the mode of ground joint bar 4, the positioning section 2-1 of U-bend reinforcing bar 2 opening both sides is fixed on flooring subsequently;
3) U-shaped angle moment reinforcement 7 is used, by two U-shaped angle moment reinforcements 7 respectively from the two of corner post when reinforcing corner post Individual unsettled side is inserted in, and is enclosed within the bottom of template 1, and pad is placed on batten 3, two U-shaped angle moment reinforcement 7 mounted on top, so Rear two U-shaped angle moment reinforcements 7 of stretching of exerting oneself respectively, tightly fix the template 1 of two unsettled sides of corner post, land used subsequently The positioning section 7-1 of two U-shaped angle moment reinforcement 7 opening both sides is fixed on flooring by the mode of face joint bar 4;
Owing to corner post has two side templates to be in unsettled side (outside punching), therefore employing 2 U-shaped angle moment reinforcement 7 is to corner post The template 1 of two the unsettled sides (outside punching) in bottom is reinforced.
4) link normally reinforce post template 1 according to arrangement and method for construction subsequently, checked and accepted, treats that this layer concrete pours Complete and when allowing to tear open post template 1, U-bend reinforcing bar 2 or U-shaped angle moment reinforcement 7 are disassembled standby.
Seeing Fig. 2, the reinforcing moment reinforcement that a kind of pillar anti-faulting of slab ends construction method is used, including U-bend reinforcing bar 2, U The interlude of type moment reinforcement 2 becomes U-shaped, is provided with the positioning section 2-1 bent at an angle of 90 in the both sides of U-shaped opening;U-type groove end The a length of b+2t of flat segments, wherein b is template width, and t is template thickness.
Owing to can produce bending radius during bar bending, therefore the bent angle of both sides, U-type groove end is radius is that (d is reinforcing bar to 2d Diameter) 90 ° of circular arcs, it is therefore desirable to the flat segments length of U-type groove end is set as b+2t, just can make U-bend reinforcing bar 2 U-type groove end side template unsettled with side column fit tightly so that it is fixing is the most firm.
Seeing Fig. 4, the reinforcing moment reinforcement that a kind of pillar anti-faulting of slab ends construction method is used, including U-shaped angle bent steel Muscle 7, the interlude of U-shaped angle moment reinforcement 7 becomes U-shaped, and a side of U-shaped opening is provided with the positioning section 7-1, U bent at an angle of 90 Another side angle at 45 ° bending of type opening, its end bends out positioning section 7-1 again, and the positioning section 7-1 on two limits is the most flat OK;The a length of b+2t of flat segments of U-type groove end, the width of U-type groove opening part is b+2t, and wherein b is template width, and t is mould Plate thickness;It is welded with steel bar end 6 in the corner of U-type groove end edge Yu right-angle side, is used for reinforcing and shaping.
In order to ensure that the U-type groove end of U-shaped angle moment reinforcement 7 can the template of side unsettled with corner post fit tightly, make Its fixation, therefore the flat segments length of U-type groove end is set as b+2t, it is b+2t by the width setup of U-type groove opening part.
Owing to corner post has two side templates to be in unsettled side, so using 2 U-shaped angle moment reinforcements 7, utilize its U-type groove The flat segments of end fixes the template of two unsettled sides, corner post bottom respectively.
U-bend reinforcing bar 2 and U-shaped angle moment reinforcement 7 use the reinforcing bar of φ 14, and steel bar end 6 uses the reinforcing bar of φ 28.
A kind of pillar anti-faulting of slab ends construction method that the present invention proposes, the U-bend reinforcing bar 2 of employing and U-shaped angle bent steel Muscle 7 can be used for multiple times, simple to operate, and Financial cost is low, when concrete is constructed, it is possible to effectively prevent construct concreting with And the unfavorable factor brought during vibrations, it is ensured that the position of pillar is accurate, significantly more efficient prevents, and bottom spillage is wrong The generation of platform problem, and make the durability of structure and overall appearance more attractive in appearance.
