Abstract
The invention discloses an opening reinforcing method implemented after punching a hole on a cast-in-place concrete plate. The method comprises the following steps of: punching the hole (2) on the cast-in-place concrete plate (1) by using a traditional method; keeping a steel reinforcing bar (3) within partial original cast-in-place concrete plate (1) at a section of the hole (2) after the hole (2) is punched; bending the steel reinforcing bar (3) into an L shape; and then respectively fixing steel plates (6) on concrete beams of the cast-in-place concrete plate (1) at the two ends of the hole (2) by using chemical anchor bolts (5); welding channel steel (7) on the steel reinforcing bar (3) bent into the L shape; respectively welding the two ends of the channel steel (7) on the steel plates (6); and then filling a gap between the channel steel (7) and the cast-in-place concrete plate (1) by using fine stone concrete with a higher cement grade than the cast-in-place concrete plate (1). According to the opening reinforcing method implemented after punching the hole on the cast-in-place concrete plate, disclosed by the invention, the advantages of simple structure, convenience in construction, higher structural strength, lower manufacturing cost and shorter construction period are achieved.
Description
Technical field
The present invention relates to a kind of reinforcing method after In-situ cast concrete board punches, belong to building In-situ cast concrete board and to punch a mouthful reinforcing technique field.
Background technology
In the design of industrial premises, often due to the needs of technique or Specialty Design, larger hole must be newly outputed on the In-situ cast concrete board of the building of having constructed, for the reinforcing at the hole that these newly output on In-situ cast concrete board, method the most frequently used be at present on limit, hole more again pouring reinforcement concrete side bar reinforce, the problem that the method that this pouring reinforcement concrete side bar carries out reinforcing not only also exists long in time limit, constructional difficulties, wastes time and energy, but also also exist that cost of manufacture is high, the less-than-ideal problem of consolidation effect.Therefore, existing punch on In-situ cast concrete board after reinforcing method or not ideal enough.
Summary of the invention
The object of the invention is: provide that a kind of structure is simple, easy construction, structural strength is higher, cost of manufacture is lower, the duration is shorter In-situ cast concrete board punches after reinforcing method, to overcome the deficiencies in the prior art.
The present invention is achieved in that the reinforcing method after a kind of In-situ cast concrete board of the present invention punches, comprise and adopt conventional method to output hole on In-situ cast concrete board, after outputing hole, retain the reinforcing bar in one section of former In-situ cast concrete board of hole part, and by this section of reinforcing bar bending l-shaped, the concrete beam of the In-situ cast concrete board then at two ends, hole adopt chemical anchor bolts to fix a block plate respectively, channel-section steel is welded on the reinforcing bar of bending l-shaped, and the two ends of channel-section steel are welded on steel plate respectively, then adopt and than the cement grade of In-situ cast concrete board higher leveled fine-stone concrete, the gap between channel-section steel and In-situ cast concrete board to be tamped.
Above-mentioned chemical anchor bolts are the chemical anchor bolts of M16, and are no less than 180 millimeters in concrete beam chemical anchor bolts being implanted In-situ cast concrete board.
The thickness of above-mentioned steel plate is not less than 8 millimeters.
Owing to have employed technique scheme, the present invention does not need to carry out pouring reinforcement concrete side bar at outputed hole, and directly utilize original reinforcing bar and concrete beam, add and channel-section steel is connected as one as the side bar at hole and original reinforcing bar and concrete beam, not only enormously simplify construction technology and construction cost, but also substantially increase the structural strength at former hole, and the present invention is once after construction, can come into operation in its hole, substantially reduce the duration.Therefore, compared with prior art, the present invention not only has that structure is simple, the advantage of easy construction, but also has the advantage that structural strength is higher, cost of manufacture is lower, the duration is shorter in the present invention.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiments of the invention: the structure at the hole 2 after adopting the reinforcing method after a kind of In-situ cast concrete board of the present invention punches to reinforce as shown in FIG. 1 to 3, during construction, after outputing hole 2 by existing conventional method on In-situ cast concrete board 1, retain the reinforcing bar 3 in one section of former In-situ cast concrete board 1 of hole 2 part, and this section of reinforcing bar 3 is bent l-shaped, then on the concrete beam 4 of the In-situ cast concrete board 1 at two ends, hole 2, adopt chemical anchor bolts 5 to fix a block plate 6 respectively, chemical anchor bolts 5 can adopt the model that market is sold to be the chemical anchor bolts of M16, concrete beam 4 planted agent chemical anchor bolts 5 being implanted In-situ cast concrete board 1 is no less than 180 millimeters, the thickness of its steel plate 6 should be not less than 8 millimeters, then channel-section steel 7 is welded on the reinforcing bar 3 of bending l-shaped, and the two ends of channel-section steel 7 are also welded on steel plate 6 respectively, then adopt and than the cement grade of In-situ cast concrete board 1 higher leveled fine-stone concrete the gap between channel-section steel 7 and In-situ cast concrete board 1 to be tamped and all reinforcing bars 3 are all wrapped.
Claims (3)
1. the reinforcing method after an In-situ cast concrete board punching, comprise and adopt conventional method to output hole (2) on In-situ cast concrete board (1), it is characterized in that: after outputing hole (2), retain the reinforcing bar (3) in one section of hole (2) part In-situ cast concrete board (1), and by this section of reinforcing bar (3) bending l-shaped, then on the concrete beam (4) of the In-situ cast concrete board (1) at hole (2) two ends, chemical anchor bolts (5) are adopted to fix a block plate (6) respectively, channel-section steel (7) is welded on the reinforcing bar (3) of bending l-shaped, and the two ends of channel-section steel (7) are welded on steel plate (6) respectively, then adopt and than the cement grade of In-situ cast concrete board (1) higher leveled fine-stone concrete, the gap between channel-section steel (7) and In-situ cast concrete board (1) to be tamped.
