Abstract
The invention relates to a reinforcing method of a plate type overhanging component. The reinforcing and reforming technology is applied to a plate type overhanging part of constructional engineering. A device for the method mainly consists of a main reinforcement implanted in a ring beam and a pi-shaped shearing resistant reinforcement. The reinforcing method is characterized in that the main reinforcement implanted in the ring beam can effectively resist a bending moment generated at the root part of the overhanging component; and the pi-shaped shearing resistant reinforcement can effectively bond new and old concrete layers. Therefore, by using the technology, the bending moment generated at the root part of the overhanging component can be effectively resisted, and the new and old concrete layers can also be effectively bonded so as to have good reinforcing effect.
Description
Technical field
The present invention relates to the technical matters technical field that a kind of plate type overhanging component is reinforced, especially relate to a kind of reinforcement means of plate type overhanging component.
Background technology
At present, the reinforcing technique of plate type overhanging component mainly contains: method, cutter layer reinforcement method etc. at the bottom of superimposed plates method, freely-supported method, shortening jib-length method, the thickening plate.Though these methods have been brought into play positive effect to the strengthening reconstruction of plate type overhanging component, also exist following deficiency:
1, the good looking appearance degree is poor, and it is not too convenient to use.
2, the bonding reliability of levels new-old concrete be difficult to guarantee or the section area reinforced excessive, consolidation effect is undesirable.
Summary of the invention
The reinforcement means that the objective of the invention is to avoid the weak point of prior art and a kind of plate type overhanging component is provided, thus the problems of the prior art effectively solved.
The object of the invention is realized through adopting following technical scheme: the reinforcement means of described plate type overhanging component is characterized in including following steps:
(1) overhanging component upper surface 1 cutter is removed the masonry 2 of 30mm～40mm, remove the sandstone that floats, and pour water and make it smooth towards Xian;
(2) the main muscle 3 one ends degree of depth of implanting former collar tie beam 5 is not less than 150mm, crooked 90 ° of main muscle 3 other ends, and height 30mm, the end of vertically implanting overhanging component, and guarantee that the tensile strength standard value is not less than 335N/mm
2
(3) main muscle 3 in place after, the distribution bar of colligation Φ 6 spacing 200mm in the above;
(4)
shape shear reinforcement 4 diameter of phi 6 are set; Crooked 90 ° of both sides; Height 30mm; The boring of use electric drill; Pass overhanging component deck upper surface and pierce overhanging component deck 30mm; Put into
shape shear reinforcement 4 of Φ 6 spacings 300 behind the clean-out opening intraclast, reinforcing bar is staggeredly placed;
(5) erase and swim, overhanging component deck upper surface is smeared the neat slurry that has identical water/binder ratio with as placed concrete;
(6) treat neat slurry sclerosis after, build the thick C30 pea gravel concreten of 30mm, jolt ramming, press polish to original building absolute altitude, the roll extrusion pulp, once floating, cover no longer, and guarantee that the overhanging component protective layer thickness is not less than 10mm, and be not more than 15mm;
Segmentation is built when (7) constructing, and reserves constuction joint.The main muscle 3 and the distribution bar on it of described implantation interconnect with
shape shear reinforcement 4; Make after the reinforcing member stress more evenly, rationally, use more durable.
The invention has the beneficial effects as follows: the reinforcement means of described plate type overhanging component; It removes facing concrete and the buttress portion body of wall of about 30mm through cutter; Implant main muscle and
shape shear reinforcement; Overcome the deficiency of reinforcement means in the past; Can effectively resist the moment of flexure that the overhanging component root is produced, build the thick C30 pea gravel concreten of 30mm, jolt ramming, press polish to original building absolute altitude; The roll extrusion pulp; Once floating, utilize
shape shear reinforcement effectively to connect new-old concrete, consolidation effect is good.
Description of drawings
Fig. 1 is a principle schematic of the present invention.
Concrete implementation
As shown in Figure 1, the reinforcement means of described plate type overhanging component, it includes following steps:
(1) overhanging component upper surface 1 cutter is removed the masonry 2 of 30mm～40mm, remove the sandstone that floats, and pour water and make it smooth towards Xian;
(2) the main muscle 3 one ends degree of depth of implanting former collar tie beam 5 is not less than 150mm, crooked 90 ° of main muscle 3 other ends, and height 30mm, the end of vertically implanting overhanging component, and guarantee that the tensile strength standard value is not less than 335N/mm
2
(3) main muscle 3 in place after, the distribution bar of colligation Φ 6 spacing 200mm in the above;
(4)
shape shear reinforcement 4 diameter of phi 6 are set; Crooked 90 ° of both sides; Height 30mm; The boring of use electric drill; Pass overhanging component deck upper surface and pierce overhanging component deck 30mm; Put into
shape shear reinforcement 4 of Φ 6 spacings 300 behind the clean-out opening intraclast, reinforcing bar is staggeredly placed;
(5) erase and swim, overhanging component deck upper surface is smeared the neat slurry that has identical water/binder ratio with as placed concrete;
(6) treat neat slurry sclerosis after, build the thick C30 pea gravel concreten of 30mm, jolt ramming, press polish to original building absolute altitude, the roll extrusion pulp, once floating, cover no longer, and guarantee that the overhanging component protective layer thickness is not less than 10mm, and be not more than 15mm;
(7) because of construction area is bigger, segmentation is built during construction, reserves constuction joint.
The main muscle 3 and the distribution bar on it of described implantation interconnect with
shape shear reinforcement 4; Make after the reinforcing member stress more evenly, rationally, use more durable.
