Description

A kind of linkage of falsework rod member

Technical field

The utility model relates to a kind of linkage, on especially a kind of column that is fixed on falseworks such as scaffold or frame and can connect the linkage of cross bar and brace.

Background technology

Often need to use falseworks such as scaffold or frame in the layout of building and decoration, stage lighting or exhibition and work high above the ground, being connected between its cross bar and brace and the column typically uses the chrysanthemum dish or old partition ring terminal pad connects.In use, find that these traditional terminal pads have the following disadvantages: (1) snapping bit quantity is few, and the snapping bit quantity of chrysanthemum dish mostly is 8 most, and the snapping bit quantity of old partition ring terminal pad has only 4; (2) the chrysanthemum dish can only be connected with horizontal direction with old partition ring terminal pad, as wants translation-angle then to need a conversion equipment to finish; (3) chrysanthemum dish and old partition ring terminal pad will with the hands be linked up with in operating process, during hook taking even need tool using just can finish; (4) because the complexity of operation causes operating efficiency on the low side.

The utility model content

The purpose of this utility model is to solve the problem of above-mentioned existence, and the linkage of the falsework rod member of the many and easy accessibility of a kind of simple in structure, snapping bit quantity is provided.

For achieving the above object, the technical solution of the utility model is achieved in that the linkage that a kind of falsework rod member is provided, and comprises the sleeve on the column that is placed on falsework; The snapping part that is used for snapping cross bar and brace is located on the excircle side of described sleeve; Wherein, described snapping partly comprises four snapping unit that are crossing distribution, and each snapping unit is made of end to end a brace lock joint rod, a cross bar lock joint rod and another root brace lock joint rod.

For strengthening the connection reliability of its structure, described column adopts pipe support, aluminum pipe for example, the inner circumferential side mask of described sleeve have with the tube wall that is formed on described pipe support on the mesh groove of flange engagement.Described mesh groove can be two or many cannelures.

For further strengthening its reliability of structure, described sleeve also is provided with the dowel hole that penetrates its sidewall.

Preferably, described snapping unit is " Qian " shape.

The cast steel member that described sleeve and snapping part can be formed in one.Certainly, sleeve and the also moulding separately of snapping part partly are welded on snapping on the excircle side of sleeve then.

For further strengthening its reliability of structure, the junction of described brace lock joint rod and described sleeve and described cross bar lock joint rod is respectively arranged with reinforcing rib.

Compared with prior art, linkage of the present utility model has following advantage:

(1) the snapping bit quantity is many: 12 snapping positions can be provided at most, increase 4-8 than chrysanthemum dish and old partition ring terminal pad.

(2) simple in structure: when the clasp of cross bar and brace was connected on the corresponding lock joint rod, angle can be carried out 180 degree and be need not to increase conversion equipment with interior freely the conversion.

(3) conveniently assemble and disassemble: can finish and not need with one hand during connection and dismantle with instrument.

(4) high efficiency: through initial estimate, this kind easy-to-install linkage can improve 20%-50% with respect to the operating efficiency of chrysanthemum dish and old partition ring terminal pad.

In sum, the utility model is simple in structure, the snapping bit quantity is many, easy accessibility, high efficiency, can be widely used in the falseworks such as various scaffolds or frame.

The utility model is described in further detail below in conjunction with drawings and Examples.

The specific embodiment

Referring to Fig. 1 to Fig. 3, the cylindrical sleeve 2 that is hollow in the linkage 1 of a kind of falsework rod member of the present utility model comprises, the excircle side of this sleeve 2 is provided with the snapping part 3 that is used for snapping cross bar shown in Figure 4 42 and brace 43, the integral cast steel member that described sleeve 2 and snapping part 3 are formed in one.Certainly, described snapping part 3 can also be fixedly connected on the excircle side of this sleeve 2 by modes such as welding.

Referring to Fig. 2, described snapping part 3 comprises four snapping unit 31 that are crossing distribution, each snapping unit 31 is made of end to end a brace lock joint rod 311, a cross bar lock joint rod 312 and another root brace lock joint rod 313, the brace lock joint rod 311 of cross bar lock joint rod 312 and a side and the brace lock joint rod of opposite side 313 are vertical respectively, thus each snapping unit 31 formation " Qian " shape.Certainly, can also form acute angle or obtuse angle between cross bar lock joint rod 312 and the brace lock joint rod 311,313, and not necessarily form the right angle.For further strengthening its reliability of structure, the junction of brace lock joint rod 311,313 and cross bar lock joint rod 312 is respectively arranged with reinforcing rib 314,315, and the junction of brace lock joint rod 311,313 and sleeve 2 is provided with reinforcing rib 316.Thus, each snapping unit 31 respectively forms three snapping positions, and the snapping part 3 of each linkage 1 has just formed 12 snapping positions altogether.

Referring to Fig. 3, the inner periphery side of this sleeve 2 is formed with two ringwise mesh grooves 21,22.Certainly, above-mentioned mesh groove also can only have one, also can be provided with many as required.This sleeve 2 also is provided with the dowel hole 23 that penetrates this sidewall on the sidewall between mesh groove 21 and the mesh groove 22, utilize unshowned alignment pin radially to pass sleeve 2 and column 41, can strengthen the connectivity robustness between this sleeve 2 and the column 41.Certainly, this dowel hole 23 is not essential.

Referring to Fig. 4 to Fig. 8, sleeve 2 is nested with and is fixed on the aluminum pipe support 41 of scaffold 4, be formed on the

mesh groove

21,22 on the inner periphery side of sleeve 2 and be formed on flange 411 engagements on the tube wall of column 41, it is fastening spacing that sleeve 2 is realized in the axial direction with respect to column 41.Cross bar 42 utilizes its clasp 421 to snap onto on the cross bar lock joint rod of snapping unit 31, brace 43 utilizes its clasp 431 to snap onto on the brace lock joint rod of snapping unit 31, can finish and not need with one hand during connection and dismantle, and angle can be carried out 180 degree and be need not to increase conversion equipment with interior freely the conversion with instrument.

Referring to Fig. 9 and Figure 10, below explanation is how with linkage 1 fastening being installed on the column 41: at first linkage 1 and column 41 are located, linkage 1 is supported on the supporting seat 53; Extruding rod 52 with hydraulic die 5 puts in column 41 inner chambers then; The hydraulic oil of then annotating in hydraulic jack 54 will push rod 52 pulling downwards; When extruding rod 52 moved downward, four ring sets 51 that its terminal wedge-shaped sleeve 55 will be arranged between this wedge-shaped sleeve 55 and the column 41 outwards strutted, and ring set 51 utilizes the projection 511 of its periphery that column 41 is extruded two flanges 411.Article two, flange 411 meshes with

mesh groove

21,22 respectively, makes linkage 1 and column 41 secure fit.Between mesh groove 21 and mesh groove 22, use pin to position reinforcing at last.This fastening means can effectively solve the adhesive failure problem that exists in the middle of traditional fastening means, and can reduce production costs effectively.
