Abstract

The utility model relates to a cap type pressing rod for a safety supporting scaffold, which is characterized in that: square caps are arranged at two ends of a pressing rod with a certain length; the square caps are used for connecting adjacent pressing rods; the square caps are longitudinally symmetrical and are respectively fixed at two ends of the pressing rod; 2-3 bolt holes which are linked with a horizontal cross rod are distributed on the side walls of an upper cap and a lower cap; the pressing rods can be manufactured by using seamless hollow steel pipes, solid steel pipes, solid and hollow alternated steel pipes along length direction or other materials with required rigidity and strength according to a bearing requirement; and 4 or 8 bolt holes for linking the adjacent pressing rods are respectively distributed on the top walls of the upper cap and the lower cap. The cap type pressing rod provided by the utility model realizes standard construction of the scaffold. A safe, convenient, quick and reliable method is supplied to the specification for the construction design, modeling, calculation and manufacturing of the scaffold, the standard element erection and the specialized construction.

Description

The depression bar that hat type safety supports scaffold is used

Technical field

The utility model relates to a kind of member of support scaffolding, the depression bar that especially a kind of hat type safety supports scaffold is used.

Background technology

Scaffold is the temporory structure that construction work is usually used: as the operation platform that makes things convenient for the engineering construction operation to set up, or build the rack template project that provides process to support as permanent works.Because scaffold belongs to temporary works, can not get the due enough attention of people, make the scaffolding work development incompatible with current engineering construction demand, expose the distortion of scaffold construction potential safety hazard and scaffold and cause the template variation, even cave-in accident appears, jeopardizes construction engineering quality and uses function.

Depression bar is the main bearing carrier of support scaffolding, and it and other member must carry out reliable rigid connection.Before proposing, the application not yet sees identical depression bar member.

Summary of the invention

The depression bar that the utility model provides a kind of hat type safety supports scaffold to use, it is conducive to scaffold installs fast and firmly, has advantage simple in structure and easy to use.

The technical scheme that the utility model is taked is as follows:

The depression bar that a kind of hat type safety supports scaffold is used, the depression bar two ends that it is characterized in that certain-length respectively are provided with one for the square cap that is connected with adjacent press, the upper and lower symmetry of described square cap is separately fixed at the depression bar two ends, respectively distributes in upper cap and lower cap side 2-3 to be used for the bolt hole that connects with horizontal cross bar.

Described depression bar can be selected seamless hollow steel pipe or solid steel pipe according to the carrying needs, or solid and hollow steel pipe separately along its length, or other satisfies material making of required rigidity and intensity.

4 or 8 bolts hole that are used for connecting adjacent press respectively distribute on described upper cap and the lower crown face.

This hat type safety supports scaffold depression bar that the utility model proposes, solved the problem of scaffold standard construction, for working design, the type selecting of standard scaffold, calculate, be made as that standard component is set up and specialized construction provides safe, convenient, quick, reliable approach.

Description of drawings

Fig. 1 is the safety supports scaffold figure that hat type depression bar and neighbouring depression bar and horizontal cross bar connect assembling.

Fig. 2 is hat type pressure rod structure figure.

Fig. 3 is the I-I sectional drawing of Fig. 2.

Number in the figure: 1-hat type depression bar, 2-horizontal cross bar, the upper cap of 3-, cap under the 4-, 5-bolt hole.

The specific embodiment

Shown in Fig. 1～3, the depression bar length L that hat type safety supports scaffold is used is by 0.5m, 1.0m, 1.5m, 2.0m, 2.5m or the manufacturing of 3.0m equal modulus, and external diameter is Φ, can be fabricated to internal diameter according to the carrying needs Φ 1Seamless hollow steel pipe or solid steel pipe, or solid and hollow separately round steel pipe, or other material that satisfies required rigidity and intensity is made.

It is the board making of d that the laterally zygomorphic upper cap in depression bar two ends and lower cap all adopt thickness, and cap is square, and the length of side is b, highly is (b- Φ)/2.

In the end face b of upper cap and lower cap width range, apart from h place, depression bar center each evenly distribute four or around eight bolts hole that distribute, the aperture is Φ 2Be used for the connection of neighbouring depression bar.

Cap altitude range (b-at upper cap and lower cap ΦIn)/2, distribute apart from the position of end H 2 or 3 apertures of every side are Φ 2Bolt hole, be used for horizontal cross bar and connect.

Depression bar can mate combination according to size and the depression bar length modulus of support bearing load in two vertical planes, form the combination safety supports scaffold under the multiple depression bar length modulus.

The material that depression bar can adopt seamless steel pipe or other to satisfy mechanical performance index is made.

Claims
