Abstract
The utility model relates to a horizontal entrance to a cave safety device, its characterized in that: horizontal entrance to a cave safety device is aided with two -way reinforcing bar net at the horizontal entrance to a cave, in the exposed reinforcing bar end anchor income entrance to a cave boundary beam of two -way reinforcing bar net, and the cast in situ concrete face, then completely spread the template on the net at the reinforcing bar, form the horizontal entrance to a cave safety device of double -deck dual fail -safe. Adopt the two -way anchor of phi 6@100 -150 to go into the cast in situ concrete beam slab, be equipped with full shops template alright become safety protection method easy and simple to handle, quick effectual, this novel construction process ann, tear the convenience open, reduce artifical timely, the characteristics such as the security performance is good, resources are saved that drop into, protect.
Description
Technical field
The utility model belongs to construction engineering technical field, specifically a kind of horizontal hole safety device.
Background technology
Horizontal hole is the common form in building, such as: reserved opening, elevator shaft mouth, floss hole etc., belong to " four mouthfuls " in building construction, the security incident such as high falling, object strike often occurs, must carry out security protection during construction.
Safety management is the most important thing of engineering management, be related to all site operations, the life of administrative staff and the safety of property, hit main with falling from high altitude and object again in room is built, and horizontal hole is that one of maximum place of this type of accident occurs, main manifestations is that original protective equipment destroys by construction operation personnel, causes constructor to trample falling or object falls from hole and hits bottom personnel etc.In traditional housing construction, the protection for horizontal hole mainly adopts scaffold to be aided with safety net and foot rest carries out the facade protection of horizontal hole.The method is said from security standpoint and is met security protection requirement, but there is following drawback:
1, hole easily has after protection is removed and carries out the construction material transmission of levels by constructor, afterwards not Active recovery, thus it is not in place to form this hole provisional protection;
2, too loaded down with trivial details, operation is many, and material requested is wide in variety, and needs special scaffolder to set up;
3, due to present rapid construction, carry out the construction of a upper floor operation while the protection of horizontal hole is carried out in the existence of most building sites, form top-bottom cross operation, there is potential safety hazard;
4, most horizontal hole later stage all will carry out building wall, needs dismounting place where troops were originally stationed to protect and is then protecting from inside, add working procedure, cause and repeat construction, add cost of labor;
5, protection is generally soft protection, cannot inherently prevent artificial to parabolic in hole, or the dropping of the unexpected top construction material caused.
Summary of the invention
The purpose of this utility model is to provide a kind of horizontal hole safety device, and its construction is simple, convenient, fast, and security protection is timely, security performance good, decreases artificial input, reduces cost, increase work efficiency.
The technical solution of the utility model is: a kind of horizontal hole safety device, two-way concrete slab net is aided with at horizontal hole, the exposed reinforcement end of two-way concrete slab net anchors in the side bar of hole, cast in place concrete plate face, then on steel mesh reinforcement, completely spread template, form the horizontal hole safety device of double-layered, double-safety.
Described two-way concrete slab net adopts the two-way establishment of Φ 6100-150, and the exposed reinforcement end of two-way concrete slab net anchors into hole side bar and is greater than 50mm apart from edge, hole, and the exposed reinforcement end of two-way concrete slab net anchors into the degree of depth >=100mm of hole side bar.
Horizontal hole of the present utility model safety device, the security protection of bilayer, dual fail-safe, has the following advantages:
1, construct simple, convenient, fast, single steel bar is lightweight, and single workman gets final product independent operation, and pacify, tear open simple and convenient, speed of application is fast, compared with traditional pin hand cradle technique, can improve work efficiency 50%;
2, security protection is timely, security performance good, and reinforced mesh horizontal hole protection when structure reinforcing bars completes just completes, and for the construction of follow-up teams and groups provides safety guarantee, then is aided with template and completely spreads formation hard protection, effectively prevent object from falling, improve security performance;
3, protection effect is good, not easily by artificial destruction, adopts Double-protection, not easily goes to pot, even if constructor is by the form removable on upper strata, still have the reinforced mesh of lower floor to form available protecting to hole;
4, reduce operation, avoid repeating, during secondary structure construction, compared with traditional pin hand cradle technique, do not need dismounting place where troops were originally stationed to protect and carry out again repeating protection, until remove again during last procedure, decrease artificial input, reduce cost, also improve operating efficiency simultaneously;
5, material recycling, economize on resources, protection of the environment, the reinforcing bar after dismounting and template can re-use, such as: reinforcing bar can be used for being processed into stirrup etc., lay template can adopt waste material to process use.
6, in construction, protection effectively can stop the construction rubbish dropped on top, keeps the highly civilized health of next floor, and then keeps the civilized construction of whole working face, thus ensures on-the-spot good construction image.
Accompanying drawing explanation
Fig. 1 is horizontal hole of the present utility model safety device floor map.
Fig. 2 is the A-A sectional drawing in Fig. 1.
In figure: edge, 1-hole, 2-two-way concrete slab net, 3-embeds reinforcing bar, 4-cast in place concrete plate face, and 5-reinforcing bar inserts concrete length, 6-hole side bar.
Detailed description of the invention
As shown in the figure, horizontal hole of the present utility model safety device, two-way concrete slab net 2 is aided with at horizontal hole, the exposed reinforcement end of two-way concrete slab net anchors in hole side bar 6, cast in place concrete plate face 4, then on steel mesh reinforcement, completely spread template, form the horizontal hole safety device of double-layered, double-safety.
Described two-way concrete slab net adopts the two-way laying of Φ 6100-150 (carrying out reinforced mesh laying by spacing 100 ~ 150mm to reserved opening position), the exposed reinforcement end of two-way concrete slab net anchors into hole side bar and is greater than 50mm apart from edge, hole, and the exposed reinforcement end of two-way concrete slab net anchors into the degree of depth >=100mm of hole side bar.
Single workman gets final product independent operation, and pacify, tear open simple and convenient, speed of application is fast, compared with traditional pin hand cradle technique, can improve work efficiency 50%.
Technical maturation, construction speed are verified in project construction soon at home.Do not need the construction, the administrative staff that increase novel equipment and high professional qualification in implementation process, use on-the-spot personnel and equipment can to finish the work content, whole implementation is effective, can widely popularize in engineering construction.
