Description
Technical field
The utility model relates to steel pipe scaffold field, relates in particular to a kind of anti-horizontal movement scaffold hook.
Background technology
At present the steel pipe support kind on building site is a lot, and the trend of oriented tool, normalization development.Use steel pipe support inevitably to need connector, interconnecting of all vertical rods, cross bar, inclined support bar and scaffold floor is all to complete by connector.In prior art, comparatively effort of connector poor stability, installation and removal, the problem exposed day by day such as efficiency of construction is low is out.For example, Chinese patent ZL200820040965.3 provides a kind of " self-locking type scaffold hook ", and this hook is made up of " C " shape hanger bulk, snap close, back-moving spring and stop pin etc., is provided with arc elongated slot and lockpin hole in snap close.This hook is when in the service portion income holding tank of snap close swinging end, and in the time of released state, spring forces sticking department to enter the circular hole unit of one end of the service portion of close snap close swinging end in long arc-shaped holes, form the position and lock structure under released state with this, make to dismantle scaffold, link up with need to depart from rod member time, only use an external force by after snap close, can lock it in this position, be convenient to the dismounting of scaffold.The hook of this structure, links up with that cross bar is held tightly to dynamics is low when mounted, and anti-horizontal movement ability can unclamp hook by reverse compression spring in the time that snap close is subject in the other direction power, and cross bar is easily jumped out in hook, has major safety risks.Chinese patent ZL200910191647.6 provides " a kind of construction scaffold hook ".This hook, on the basis of aforementioned patent, is set up second locating hole in snap close position, the position of this second locating hole is at deep-slotted chip breaker follower head place.This patent is as the improvement on above-mentioned patent basis, by set up the design of a locating hole in deep-slotted chip breaker rear end, for snap close has increased a locked function, when latching under snap close action of reset spring, cross bar is locked in hook, on alignment pin, insert in the locating hole of newly establishing location division, thereby force snap close to remain on locking state and by locked.This structural reinforcing the steadiness connecting between steel pipe, but complicated structure, it is very inconvenient to load and unload, and while needing to take out hook, must apply certain power to hook, it is very inconvenient to operate.
Utility model content
For the defect of prior art, the utility model aims to provide a kind of anti-horizontal movement scaffold hook, can reduce and even eliminate hook displacement in the horizontal direction, reduces potential safety hazard, the utility model is simple in structure, easy making process, stable performance, safe and reliable.
In order to realize above-mentioned technical purpose, the utility model adopts following technological means: a kind of anti-horizontal movement scaffold hook, comprise hanger bulk, locking plate and alignment pin, described hanger bulk front end semicircular in shape, rear end is the connecting portion for joint steel pipe or scaffold floor, it is characterized in that: described locking plate one end is articulated in hanger bulk by alignment pin, the other end extends beyond the tie point between hanger bulk front-end and back-end; Described locking plate can rotate and form an arc inner chamber with hanger bulk in front and back.
Further, described locking plate is curved and be divided into large and small two ends, and the width of the large end of described locking plate is not more than the width of hanger bulk, and the width of described locking plate small end is less than the width of the large end of locking plate, and the large end of described locking plate is articulated in hanger bulk by alignment pin.
The beneficial effects of the utility model: the anti-horizontal movement scaffold hook of one that the utility model provides, can reduce and even eliminate hook displacement in the horizontal direction, improve stability and the bonding strength of hook, reduce potential safety hazard.When installation, directly hook button is hung on steel pipe, locking plate forces hook to remain on tightening state and can not be along horizontal motion; When dismounting, only need to apply a less power and upwards promote hook, while making the spacing of the clamping face of locking plate lower end and hanger bulk be greater than the diameter of steel pipe, can simply take out.The utility model has enough intensity, rigidity and stability, ensures construction smoothly and safety.The utility model is simple in structure, easy making process, stable performance, safe and reliable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in seeing figures.1.and.2, the anti-horizontal movement scaffold hook of one that the utility model provides, comprise hanger bulk 1, locking plate 2 and alignment pin 3, described hanger bulk 1 front end semicircular in shape, rear end is the connecting portion for joint steel pipe 6 or scaffold floor, described locking plate 2 one end are articulated in hanger bulk 1 by alignment pin 3, and the other end extends beyond the tie point between hanger bulk 1 front-end and back-end; Described locking plate 2 can rotate and form an arc inner chamber with hanger bulk 1 in front and back.When installation, directly hanger bulk 1 button is hung on steel pipe 6, locking plate 2 forces hook to remain on tightening state and can not be along horizontal motion; When dismounting, only need to apply a less power and upwards promote hook, while making the spacing of the clamping face of locking plate 2 lower ends and hanger bulk 1 be greater than the diameter of steel pipe 6, can simply take out.
Shown in Fig. 3, as preferred embodiment, described locking plate 2 is curved and be divided into large and small two ends, the width of described locking plate 2 large ends 4 is not more than the width of hanger bulk 1, the width of described locking plate 2 small ends 5 is less than the width of locking plate 2 large ends 4, and the large end 4 of described locking plate 2 is articulated in hanger bulk 1 by alignment pin 3.
Shown in Fig. 4, disassembly process of the present utility model is: when installation, described hanger bulk 1 correspondence is buckled and is being positioned on its steel pipe 6 below tiltedly, in installation process, locking plate 2 changes according to the diameter occurrence positions of steel pipe 6, locking plate 2 is along with steel pipe 6 front and back are rotated and form an arc inner chamber with hanger bulk 1, and steel pipe 6 is locked by locking plate 2 in this arc inner chamber.Due in the time that arc inner chamber pins steel pipe 6, the spacing of the clamping face of locking plate 2 lower ends and hanger bulk 1 is less than the diameter of steel pipe 6, thereby the utility model can be locked steel pipe 6, the relative motion up and down of hook and the movement of horizontal direction are limited, can reduce and even eliminate hook displacement in the horizontal direction, improve stability and the bonding strength of hook, reduce potential safety hazard.
Accordingly, when dismounting, apply a less power and upwards promote hook, while making the spacing of the clamping face of locking plate 2 lower ends and hanger bulk 1 be greater than the diameter of steel pipe 6, linking up with can be in the time of the horizontal direction activity of steel pipe 6, and scaffold folding stair can be disassembled.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
