Abstract

The utility model discloses a connecting part of scaffold, in particular to a positioning rotary table of a direct plug type self-locked scaffold. The utility model comprises a table body whose center is provided with a round inner hole whose circumference is provided with a plurality of plug connector so as to connect with a plurality of plugs. The plug connectors are wedge shaped, one end of the plug connector is communicated with the inner hole. The utility model has the advantages of simple and effective structure, compact appearance, easy assembly and disassembly, distortion-proof, high degree of reliability and high safety factors. The utility model solves the problems of unscientific structure, large amount of needed components, complex assembly and disassembly, high manufacturing cost and low safety factors in prior positioning of scaffold.

Description

The location wheel disc of direct insertion self-locking scaffold

Technical field

The utility model relates to a kind of assembly for scaffold for building, particularly relates to a kind of structural improvement of positioner of scaffold upright rod.

Background technology

In the modern architecture industry, scaffold is a requisite temporory structure in the construction, mainly be to make the constructor can carry out operation aloft, therefore to fastness, security requirement is than higher, this just to building of scaffold higher requirement, scaffold generally includes cross bar, vertical rod, brace and linkage, linkage generally adopts steel pipe chuck or connection fastener, though two kinds of linkage safety factor waste time and energy when than higher, installing and dismantling, and have reduced speed of application, connection fastener is lost again easily, has brought inconvenience to construction.In order to solve these technical problems, Chinese patent (the patent No.: 94119500.7) disclose a kind of means for fastening scaffolding, by have in the vertical rod weldering card bowl thereon and can be thereon movable clip, two ends have the cross bar of buckle, and form with the alignment pin of vertical rod one, the contact surface of buckle and card bowl is the taper surface with angle, said angle can make and form the self-locking connection between vertical rod and the cross bar, the card bowl is a bowl structure, its inner surface is a conical surface, the outside of buckle is the face of cylinder, and inboard taper surface with the card bowl has same tapering.When using, connect vertical rod and cross bar, conical surface contact just formation self-locking, though this device has reduced assembly, reduce cost, improved the speed of building, but owing to be that the card bowl is bowl structure, final bowl wall can be concentrated and bear very big pressure, rigidity there is very high requirement,, in use also has certain risk so the time has been grown card bowl easy deformation, life-span is not long, and safety factor is not high.

Summary of the invention

The utility model is unreasonable for the structure that solves the existence of existing scaffold connection positioner, required part number is more, technical problems such as loading and unloading are complicated, and manufacturing cost is higher, and safety factor is low, provide a kind of simple in structure effective, profile is simple and direct, and is easy to loading and unloading, not yielding, the reliability height, the scaffold that safety factor is high connects positioner.

The technical solution of the utility model is achieved in that the location wheel disc of direct insertion self-locking scaffold, disk body, be provided with the endoporus of a circle in the disk body center, it is characterized in that being provided with some plug connectors at the endoporus peripheral region, described plug connector is the wedge shape socket, and an end of plug connector is communicated with endoporus.

As preferably, described plug connector number is 4, is the periphery that an angle of 90 degrees is evenly distributed on endoporus each other.

As preferably, on the card of the disk body between two adjacent plug connectors, be provided with the fan-shaped former of depression respectively.

Be to increase the bearing strength of plug connector, as preferably, be provided with reinforcing rib in the outer rim of plug connector.

Whole stressed even for guaranteeing wheel disc, the intensity at enhancing edge as preferably, also is provided with on the disk body periphery along the protuberance muscle of circumferential sealing.

Compare with existing scaffold upright rod positioner, the utlity model has following advantage: owing to adopted the structure of wheel disc, component have been reduced, reduce manufacturing cost, improved installation rate, and with respect to bowl structure, wheel disc vertically and radial force point is even distributes, can be stable bear bigger load, so both reduced the risk of device distortion, improved safety again greatly.

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is user mode figure of the present utility model.

The specific embodiment

The specific embodiment of the present utility model is as follows: as shown in Figure 1, according to scaffold of the present invention location wheel disc, has a roughly disk body 1 of quadrangle profile, the four edges frame 8 camber line indents of disk body 1 are also symmetrical in twos, symmetry is in twos all protruded also to bull nose in four corners 7 of disk body 1, be provided with endoporus 2 in disk body 1 centre, endoporus 2 be shaped as circle, be complementary with the outer contour shape of scaffold upright rod cross section, make the location wheel disc can be set on the scaffold upright rod just, peripheral region at endoporus 2 is provided with four plug connectors 3, be each other on the periphery that an angle of 90 degrees is evenly distributed on endoporus 2, the openend of described plug connector 3 is communicated with endoporus 2, as shown in Figure 2, the backward end of the openend of plug connector 3 is ramped shaped from bottom to top, and the slope is the contact surface of plug connector 3 and cross bar attachment plug, as shown in Figure 3, the angle on slope can make plug connector 3 and cross bar attachment plug formation self-locking be connected just.

In order to save materials, whole stressed even for guaranteeing wheel disc, strengthen the intensity at edge, between two adjacent plug connectors 3, be provided with the fan-shaped former 4 of depression, the outer camber line 9 of described fan-shaped former 4 and frame 8 are parallel and be complementary, the circular arc line of the endoporus 2 between the interior camber line 10 of fan-shaped former and the two adjacent plug connectors 3 is parallel and be complementary, two sidelines that connect the interior camber line 10 of fan-shaped former and outer camber line 9 respectively with parallel matching of edge of adjacent plug connector 3, as shown in Figure 2, for increasing the bearing strength of plug connector 3, outer rim at the plug connector is provided with reinforcing rib 5, and is whole stressed even for guaranteeing wheel disc, strengthens the intensity at edge, as preferably, on disk body 1 periphery, also be provided with the protuberance muscle 6 that seals along circumferentially.

Above-mentioned only is a specific embodiment of the present utility model, it and the cross bar attachment plug use that combines, and above-mentioned location wheel disc is a preferred forms, is welded as a whole with vertical rod after also can being enclosed within the vertical rod again.
