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
Hole reinforcement means after the present invention relates to punch on a kind of In-situ cast concrete board belongs to the building In-situ cast concrete board mouthful reinforcing technique field that punches.
Background technology
In the design of industrial premises; Often because the needs of technology or Specialty Design; Must on the In-situ cast concrete board of the building of having constructed, newly leave bigger hole; Reinforcing for these holes of on In-situ cast concrete board, newly leaving; At present the most frequently used method is to build reinforced concrete boundary beams more again to reinforce on the limit, hole, thisly builds the problem that method that reinforced concrete boundary beams reinforces not only exists long in time limit, constructional difficulties, wastes time and energy, but also exists cost of manufacture height, the less-than-ideal problem of consolidation effect.Therefore, existing hole reinforcement means after punching on the In-situ cast concrete board still is not ideal enough.
Summary of the invention
The objective of the invention is: the hole reinforcement means after punching on the In-situ cast concrete board of a kind of simple in structure, easy construction is provided, structural strength is higher, cost of manufacture is lower, the duration is short, to overcome the deficiency of prior art.
The present invention is achieved in that the hole reinforcement means after punching on a kind of In-situ cast concrete board of the present invention; Comprise and adopt conventional method on In-situ cast concrete board, to leave the hole; After leaving the hole, keep the reinforcing bar in one section former In-situ cast concrete board of hole part, and this section reinforcing bar is bent into the L type; On the concrete beam of the In-situ cast concrete board at two ends, hole, adopt chemical anchor bolts to fix a block plate respectively then; Channel-section steel is welded on the reinforcing bar that is bent into the L type, and the two ends of channel-section steel are welded on respectively on the steel plate, adopt then and the slit between channel-section steel and the In-situ cast concrete board is tamped than the higher leveled fine-stone concrete of the cement grade of In-situ cast concrete board.
Above-mentioned chemical anchor bolts are the chemical anchor bolts of M16, and chemical anchor bolts are implanted in the concrete beam of In-situ cast concrete board and be no less than 180 millimeters.
The thickness of above-mentioned steel plate is not less than 8 millimeters.
Owing to adopted technique scheme, the present invention need not build reinforced concrete boundary beams at the hole of being left, and directly utilizes original reinforcing bar and concrete beam; Add channel-section steel is connected as one as the side bar at hole and original reinforcing bar and concrete beam; Not only simplified construction technology and construction cost greatly, but also improved the structural strength at former hole greatly, and the present invention in case the construction finish after; Can come into operation in its hole, shortened the duration greatly.Therefore, the present invention compared with prior art, advantage simple in structure, easy construction that the present invention not only has, but also have that structural strength is higher, cost of manufacture is lower, advantage that the duration is short.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description.
Embodiments of the invention: the structure at the hole 2 after adopting hole reinforcement means after punching on a kind of In-situ cast concrete board of the present invention to reinforce such as Fig. 1～shown in Figure 3; During construction; By the existing conventional method after leaving hole 2 on the In-situ cast concrete board 1, keep the reinforcing bar 3 in the former In-situ cast concrete board 1 of one section hole 2 part, and this section reinforcing bar 3 be bent into the L type; On the concrete beam 4 of the In-situ cast concrete board 1 at 2 two ends, hole, adopt chemical anchor bolts 5 fixing block plates 6 then respectively; It is the chemical anchor bolts of M16 that chemical anchor bolts 5 can adopt the model of selling on the market, and concrete beam 4 planted agents that chemical anchor bolts 5 are implanted In-situ cast concrete board 1 are no less than 180 millimeters, and 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 that is bent into the L type; And the two ends of channel-section steel 7 also are welded on respectively on the steel plate 6, adopt then than the higher leveled fine-stone concrete of the cement grade of In-situ cast concrete board 1 slit between channel-section steel 7 and the In-situ cast concrete board 1 is tamped, and all reinforcing bars 3 all wrapped.
Claims (3)
1. the hole reinforcement means after punching on the In-situ cast concrete board; Comprise and adopt conventional method on In-situ cast concrete board (1), to leave hole (2); It is characterized in that: after leaving hole (2); Keep the reinforcing bar (3) in the former In-situ cast concrete board of one section hole (2) part (1); And this section reinforcing bar (3) is bent into the L type, and 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 then, channel-section steel (7) is welded on the reinforcing bar (3) that is bent into the L type; And the two ends of channel-section steel (7) are welded on respectively on the steel plate (6), adopt the higher leveled fine-stone concrete of cement grade than In-situ cast concrete board (1) that the slit between channel-section steel (7) and the In-situ cast concrete board (1) is tamped then.
