Description
Technical field
The utility model relates to a kind of formwork aid, cheats internal mold specialty setting tool specifically, belong to building operations equipment technology field in a kind of hole.
Background technology
In building operations, in several monomer B1 base plates, be provided with collecting well and elevator shaft etc., namely produce the working procedure such as reinforcing bar binding, formwork erection in hole in hole.Because hole is (as elevator shaft in general hole, collecting well) size all larger, darker, cheat after internal mold installs in so large hole, in concreting process, the buoyancy produced is quite large, long × wide × high with 2000 × 2000 × 2000() collecting well checking computations, buoyancy can reach 80KN, and the reinforcing bar binding in hole is not difficult point in hole, difficult point is the fixing of the internal mold in hole in hole, cheat in hole in the construction of internal mold concrete placings and easily occur " covering mould ", not only quality problems are produced after internal mold topples, difficulty of construction of doing over again again is also larger, General Requirements is stopped internal mold and to be toppled the generation of event.
At present, cheat in the engineering of construction in this type of hole, the way that each building site routine adopts has: 1, on internal mold, pile pressuring template or steel plate, the method is very unreliable, and due to internal mold buoyancy large, at internal mold top die plate, template piling height is higher, in casting process, buoyancy adds that concreting process is vibrated, and the template very easily producing accumulation is toppled together along with internal mold, easily security incident and quality accident occurs; Adopt steel plate to push down internal mold, steel plate area is large, and weight is large, topples also can produce security incident and quality accident with internal mold.2, pass internal mold upper surface with reinforcing bar, just connect with surface layer and welded, pushed down internal mold; The method construct, surfacing steel bar can along with toppling of internal mold on pull out, produce float distortion, and in the method actual mechanical process, the vertical direction of internal mold regulates cannot be implemented, and difficulty of construction is large, size Control difficulty is large, and needs reinforcement welding, cutting, wasting manpower and material resources.
Utility model content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, propose to cheat internal mold specialty setting tool in a kind of hole, making to cheat in hole concreting can one-shot forming, and repeatedly can have enough to meet the need use, ensure that in hole that cheat construction quality ensure that safety simultaneously.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in the following ways: provide in a kind of hole and cheat internal mold specialty setting tool, comprise square steel, round steel fixed bar, clamp nut and latch, the often end of described square steel is provided with at least two circular holes, the top of cheating internal mold in hole arranges the closure frame at least surrounded by four described square steel, and adjacent two described square steel junctions are inserted described circular hole by latch and are connected and fixed; One end of described round steel fixed bar is provided with screw thread, the other end is provided with 180 ° of crotches, and the crotch end of described round steel fixed bar is placed in bottom, hole, described hole, and crotch end hook is lived bottom reinforcement bars, the screw thread end of described round steel fixed bar passes the circular hole of square steel end, and uses clamp nut fixing and locking.
Further restriction technical scheme of the present utility model, cheats internal mold in aforesaid hole and fixes special tool, and the often end of described square steel is provided with the circular hole of four Φ 20mm, and distance 160-170mm place, square steel top is arranged, and pitch of holes is 180-200mm.
Cheat internal mold in aforesaid hole and fix special tool, described clamp nut is double nut structure.
Further, cheat internal mold and fix special tool in aforesaid hole, described round steel fixed bar is provided with eight altogether, is respectively provided with a round steel fixed bar at each square steel two ends.
The beneficial effects of the utility model are: tool making of the present utility model is simple, and easy and simple to handle, be convenient to site operation, efficiency is high, effective, and repeatedly can have enough to meet the need use; Abandon traditional laminating by template or the way of reinforcement welding compacting, traditional method is lack of standardization, and quality not easily ensures, easily security incident occurs; Use new tool, guaranteeing that internal mold construction is one-time formed while, ensure that safety, and effectively cost-saving, and setting tool can Reusability, economizes on resources, environmental protection; This tool belt bolt drag hook; together with bottom is hooked in bottom layer of the reinforcing steel; top is fastened by bolts, can the vertical direction size of vertical adjustment internal mold, guarantees that square steel compresses internal mold; internal mold fixation is reliable; when building, buoyancy is also unlikely to topple internal mold, and this instrument improves efficiency of construction greatly; and ensure that internal mold concreting one-shot forming, avoid doing over again.

Detailed description of the invention
Below the utility model is described in further detail:
embodiment 1
Cheat internal mold in the one hole that the present embodiment provides and fix special tool, structure as depicted in figs. 1 and 2, comprise square steel 1, round steel fixed bar 2, clamp nut 3 and latch 4, the often end of square steel is provided with the circular hole of four Φ 20mm, distance 165mm place, square steel top is arranged, pitch of holes is 200mm, and the top of cheating internal mold in hole arranges the closure frame surrounded by four square steel, and adjacent two square steel junctions are inserted circular hole by latch and are connected and fixed; One end of round steel fixed bar is provided with screw thread, the other end is provided with 180 ° of crotches, the crotch end of round steel fixed bar is placed in bottom, hole, hole, and crotch end hook is lived bottom reinforcement bars 5, the screw thread end of round steel fixed bar passes the circular hole of square steel end, round steel fixed bar is provided with eight altogether, is respectively provided with a round steel fixed bar at each square steel two ends, and with clamp nut 3 fixing and locking of double nut structure.
The present embodiment in use, after putting into internal mold in hole in hole, the first step, first gets 50 × 50 square steel two, laterally push down internal mold 7 top, other two 50 × 50 square steel, are longitudinally pressed on horizontal square steel, in length and breadth to square steel junction, for the circular hole of Φ 20mm, penetrate the long 100mm latch of Φ 20 and fix square steel position, four square steel are connected into closure frame, prevents square steel from indulging transverse shifting.Second step, pierce into Φ 20 round steel fixed bar at every root square steel apart from the Φ 20mm circular hole at 165mm place, end, 180 °, fixed bar bottom crotch hooks bottom reinforcement bars, and round steel fixed bar top is stubborn M20 double nut just.3rd step, internal mold adjustment, leveling, after adjustment, start symmetrical fastening M20 nut, until the requirement of internal mold size conforms formwork.
Above embodiment is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection domain.
