Abstract

The utility model provides a multipoint multidirectional automatic locking direct insertion type scaffold, and relates to a novel scaffold technology for the field of building construction. The improvement of a scaffold connecting structure is implemented in the following way that the arrangement of connecting inserting plates of an upright rod and inserting holes of the inserting plates are improved, the radial diameter of connecting inserting pieces of cross rods is flush with the outer diameter of the cross rods, the connecting inserting pieces are of an n-shaped structure in the longitudinal direction, wedge-shaped connecting plugs are arranged at the front ends of the connecting inserting pieces, wherein the cross section of each wedge-shaped connecting plug is a combination of a trapezoid and a U shape, round connecting plates connected with the cross rods are arranged at the rear ends of the connecting inserting pieces, and the height of each plug of each inserting piece of each cross rod is equal to the sum of the radius of each cross rod and the half of the height of each inserting plate. By the adoption of the multipoint multidirectional automatic locking direct insertion type scaffold, the defect that an existing direct insertion type scaffold is eccentrically stressed in connecting nodes is overcome, multipoint multidirectional automatic locking of the connecting inserting pieces of the cross rods and the connecting inserting plates of the upright rod is achieved, operation programs in the using process of the scaffold are further simplified, and a user can mount and demount the scaffold only by slightly knocking the scaffold.

Description

The tight direct plugging type scaffold of multiple spot Multidirection automatic lock

One, affiliated technical field

The utility model belongs to a kind of new type scaffold technology of building field.The deficiency that exists for solving existing scaffold, a kind of Novel direct-insert scaffold of design.

Two, background technology

Building field also has " bowl fastening type scaffold ", " dish buckle type scaffold " and " direct plugging type scaffold " except " design of coupler scaffold " that generally use at present.Wherein design of coupler scaffold is the most traditional scaffold, because market volume has suitable flexibility greatly and in using, is widely used; But this scaffold exists complex operation and set up difficult quality guarantee, and fastener the shortcoming such as easily loses, among occupation rate is in and descends gradually.Though bowl fastening type scaffold and dish buckle type scaffold make great progress than fastener type, have preferably reliability and stability since cost higher, take that to unload operation still comparatively loaded down with trivial details, so the market applicable cases is general.Direct plugging type scaffold is because its convenience and ease for operation, favored by industry, but existing direct plugging type scaffold also exists more defective and deficiency at present, particularly insert the straight cutting scaffold of dish-type, the plug of cross bar all is male type, not only plug easily impaired, be not easy to piling and deposit and carry, and because plug and the axle center of inserting the dish point of contact and departing from cross bar, easily cause the junction nodes eccentric force, the stability of scaffold and safety are had a greatly reduced quality; Also have the reliable lock of cross bar plug and vertical rod socket relatively poor, in use easily loosening; So serious restriction development and the application of direct plugging type scaffold.

The utility model is defective and the deficiency that exists for solving existing scaffold, the tight direct insertion new type scaffold of a kind of multiple spot Multidirection automatic lock of design.

Three, summary of the invention

The problem that 1, will solve

The purpose of this utility model provides a kind of Novel direct-insert scaffold.By improvement and the optimization to scaffold connecting structure, overcome junction nodes eccentric force that existing direct plugging type scaffold exists, be difficult to defective and the deficiency such as locking, further improve stability, safety and the ease for operation of scaffold.

2, technical scheme

The utility model is for solving its problem, and the technical scheme that adopts is:

(1), novel binding plug-in unit is adopted at the two ends of cross bar.The radial dimension of this binding plug-in unit flushes with the cross bar external diameter, vertically is the N-shaped structure, and front end is provided with trapezoidal wedge shape with the U-shaped compound section and links plug, and the rear end connects dish for the circle that is connected with cross bar, and the height of its plug is that the radius of cross bar adds 1/2 slotting disc thickness.(such as Fig. 2)

(2), be spaced in intervals in the vertical rod to be welded with and link insert dish.This connects patch diskette is disc, the front, rear, left and right on its plane four direction and between the position of 45 ° of directions be respectively equipped with the jack similar with diagonal brace plug cross section to the cross bar plug, the planar dimension of its jack is with the root size of plug.(such as Fig. 1)

3, beneficial effect

The utlity model has following beneficial effect:

(1), the utility model is by to the optimization of scaffold connecting structure, fundamentally overcome the defective that there is eccentric force in existing direct plugging type scaffold junction nodes, realized that rod member passes through the axle center in the power transmission of node.Further improved the safety and stability of scaffold.

(2), the utility model has been realized cross bar plug-in unit and the multidirectional phase automatic locking of vertical rod slotting dish multiple spot by the wedge type binding plug that adopts special-shaped compound section.Reliability and the ease for operation of scaffold have further been improved.

(3), the utility model is simple and easy to usefulness, without any need for accessory and tool, only needs gently one to strike to finish and take dress or dismounting during use, really realized taking fast dress and quick-detachment.

(4), the plug-in unit size of the utility model cross bar in the scope of cross bar diameter, not only solved easily impaired problem of plug, and made things convenient for the piling of rod member to deposit and carry.

(5), simple structure, low, the easy enforcement of cost.

Five, the specific embodiment

With the diameter that generally uses at present as the 48mm steel pipe scaffold as example, implement the utility model technology, at first press Fig. 5, Fig. 6 and Fig. 7, Fig. 8, Fig. 9 and Figure 10, Figure 11, Figure 12 process that vertical rod is slottingly coiled, cross bar plug-in unit and diagonal brace plug-in unit.Adopt again satisfactory φ 48*3.5 steel pipe, (length should be established different lengths in order to satisfy the various requirements of setting up by certain modulus by the length that designs, general vertical rod length can be by 600,1200,1800,2400 and 3000mm, cross bar length can by 300,600,900,1200 and 1500mm) carry out the blanking of vertical rod, cross bar and diagonal brace, cross bar and diagonal brace length will deduct the length of two ends plug-in unit during blanking.And then it is brave in vertical rod (such as Fig. 1) by the spacing of designing requirement (general 600-1200) to insert dish, with cross bar plug-in unit and diagonal brace plug-in unit respectively brave two ends at every cross bar and diagonal brace (such as Fig. 2).Can drop into engineering after qualified by inspection uses.

The utility model not only can be used for the building scaffold of common engineering, and more is applicable to the bracing frame of construction formwork.Operation is very simple in the use, and setting up only needs when installing that the plug of cross bar or diagonal brace is aimed at vertical rod and insert jack on the dish, strikes to next gently and gets final product automatic locking (such as Fig. 3, Fig. 4, Figure 13, Figure 14, Figure 15).As long as cross bar upwards one is struck, can finish the dismounting of cross bar during dismounting.
