Abstract
An aloft work anti-dropping wall clamping device belongs to the technical field of building construction auxiliary facilities. The aloft work anti-dropping wall clamping device is provided with an F-shaped clamp which is composed of an L-shaped arm and an inner clamping arm, the L-shaped arm is provided with a longitudinal rod and a transverse rod, the inner clamping arm is attached on the longitudinal rod, the transverse rod and the inner clamping arm are paralleled, an inner splint and an outer splint are respectively connected on the inner clamping arm and the transverse rod, a load applying experimental screw rod and a regulating nut to limit the position of the inner clamping arm are arranged on the longitudinal rod, and the experimental screw rod is arranged on the longitudinal rod which is arranged between the transverse rod and the inner clamping arm. The device has reasonable, scientific and simple structure, easy production and manufacture, thereby providing a reliable suspension point of a safety belt for an aloft work limb operator without the reliable safe protection, and the safety of the usage is ensured by the experiment of the experimental screw rod on the applying force of the wall clamping device.
Description
Technical field
Safety device, the especially windows etc. that the present invention relates to a kind of the realm of building construction work high above the ground personnel face the safety devices of limit operation when not having reliable protection.
Background technology
Construction site is in later stage during decoration stage, often cause the door and window at positions such as window/balcony to be installed owing to numerous reasons such as technology or duration and when winding up operation protective equipment such as scaffold removed, the operating personnel need prevent the high-altitude by means of safety belt and fall, but this type of place does not have reliable safety belt hitch point to cause this position operating personnel's safety belt not play a role mostly for a long time, and there is great hidden danger in operating personnel's personal safety.
Summary of the invention
In order to solve the anti-high-altitude of construction site later stage decoration stage operating personnel when window etc. faces the place, limit and the do not have reliable protection problem of falling, the invention provides a kind of high-lift operation drop prevention wall clamping device, this sandwich wall device can provide operating personnel's safety belt hitch point to ensure operating personnel's personal safety.
The technical solution adopted for the present invention to solve the technical problems is: high-lift operation drop prevention wall clamping device, be provided with a F clamp that constitutes by L shaped arm and interior jig arm, L shaped arm is provided with longitudinal rod and transverse bar, interior jig arm is attached on the longitudinal rod, transverse bar is parallel with interior jig arm, be connected with inner splint and external splint on interior jig arm and the transverse bar respectively, longitudinal rod be provided with the test screw rod of load application and limit in the adjusting nut of jig arm position, the test screw rod is arranged on the longitudinal rod between transverse bar and the interior jig arm.
Described inside and outside clamping plate are for bearing the circular metal plate of a constant load, metal sheet surface is provided with high abrasion resisting material coatings such as modified polyurethane elastomer, the surface layer of coating is provided with the fishnet shape groove that increases coefficient of friction, external splint is connected with the screw of transverse bar end by the small screw that its end carries, and inner splint is connected with the retaining nut on the interior jig arm by fastening bolt.The longitudinal rod of L shaped arm is provided with screwed hole, and the test screw rod is screwed in the screwed hole of longitudinal rod.
The present invention is rational in infrastructure, science, simple, manufactures easily, and facing the limit operating personnel for the high-altitude of not having reliable and secure protection provides reliable safety belt hitch point.This sandwich wall device is a F type clamp shape device, interior jig arm is a swing arm, regulate its relative position and location on the longitudinal rod of L shaped arm by a nut, inside and outside clamping plate are garden shape metallic plate, metal sheet surface (metallic plate metope side) is high abrasion resisting materials such as modified polyurethane elastomer, external splint is connected in aggregates with the L shaped arm bolt of clamp, stressed mutually to guarantee that inner splint near metope, establishes the test screw rod is set in bolt hole, the hole on L shaped arm by bolt between the jig arm in inner splint and the clamp.When the fastening bolt on the interior jig arm is subjected to a certain degree external force and screws in, between inner splint and the inner wall of building face, the corresponding generation active force of external splint with wall face, can guarantee relative fixed between sandwich wall device and the body of wall in the frictional force that produces under this active force, by the test screw rod apply parallel to the sandwich wall device with wall face and be not less than the power of a certain safety value, when sandwich wall device and skin do not have obviously as seen displacement, unclamp this sandwich wall device of test screw rod and promptly can be used as the reliable safety belt hitch point of operating personnel, the test screw rod can also double as safety belt link.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1.L shape arm, 2. interior jig arm, 3. external splint, 4. inner splint, 5. fastening bolt, 6. retaining nut, 7. adjusting nut, 8. test screw rod, 9. transverse bar, 10. longitudinal rod.
The specific embodiment
Further narrate embodiments of the invention below in conjunction with accompanying drawing.
L shaped arm 1 and the interior jig arm 2 be made up of longitudinal rod 10 and transverse bar 9 constitute the F clamp, interior jig arm 2 is connected on the longitudinal rod 10, transverse bar 9 is parallel with interior jig arm 2, be connected with inner splint 4 and external splint 3 on interior jig arm 2 and the transverse bar 9 respectively, inner splint 4 and external splint 3 all are the circular metal plates that can bear a constant load, metal sheet surface is high abrasion resisting material coatings such as modified polyurethane elastomer, the surface layer of coating is provided with the fishnet shape groove that increases coefficient of friction, external splint 3 is connected with the screw of transverse bar 9 ends by the small screw that its end carries, jig arm 2 in inner splint is connected with retaining nut 6 by fastening bolt 5.Adjusting is set on the longitudinal rod, limit, tighten up in the adjusting nut 7 of jig arm 2, between transverse bar on the longitudinal rod and interior jig arm, screwed hole is set, connect test screw rod 8 at the screwed hole inside spin.
Use when of the present invention, interior jig arm 2 in the adjusting of adjusting nut 7 down to apart from the suitable distance of interior metope, screwing in fastening bolt 5 withstands on inner splint 2 on the interior metope, fastening retaining nut 6 when strengthening fastening force gradually to suitable degree, screw in test screw rod 8 to inner face near the exterior wall concrete wall surface, strengthen Tightening moment gradually to preset value (power that this setting moment produces metope is not less than and sets safety value) on test screw rod 8, when inner splint 4, external splint 3 unclamps test screw rod 8 when not having obviously as seen displacement with metope, this moment, this sandwich wall device can be used as the anti-fall safety belt hitch point of operating personnel, and the test screw rod can also double as safety belt link.
