Technical Field

The invention relates to the technical field of building construction tools, in particular to a stably-assembled door type scaffold.

Background

Gate-type scaffold is indispensable in the construction process of building installation, gate-type scaffold adopts assembled structure mostly, traditional gate-type scaffold all is the equipment that adopts the plug-in type generally, with the horizontal pole, the pole setting, assemble through the plug connector between the diagonal brace, this kind of assembled mode though the assembly is very fast nevertheless all lacks fastening positioner between general plug connector, only simple grafting is in the same place between the various poles, the user of service is in the climbing scaffold, because of pegging graft does not forbid very easily cause the pine of plug connector to take off between each pole, cause the scaffold to collapse, cause the incident.

Disclosure of Invention

In order to solve the problems in the prior art, the utility model discloses a stably-assembled door type scaffold, the scaffold comprises 4 support columns, 4 cross rods and a plurality of grid plates, the cross rods are horizontally placed and connected with the support columns, the grid plates are placed on the cross rods, 2 mutually-perpendicular fixed blocks are horizontally arranged on the support columns, square fixed holes are formed in the fixed blocks, and the lower half parts of the exposed parts outside the fixed holes are provided with blocking bodies to form small clamping holes; correspondingly T type connecting piece has been welded respectively at the both ends of horizontal pole, the preceding side of T type connecting piece is the same with the first half size that the fixed orifices outside exposed the part, and the back side is the same with the size in card hole, the horizontal pole passes through T type connecting piece block and is connected with the support column in the fixed orifices of fixed block, open at the both ends of grid board has the arc recess, the grid board passes through the arc recess block on the horizontal pole. T type connecting piece block is in the fixed orifices, blocks the connecting piece through the fender body in little calorie of hole, makes it be difficult for droing, and the grid board is further even as an organic whole with the horizontal pole, makes whole scaffold frame become a firm whole.

Furthermore, external thread sections are arranged at the two ends of the cross rod on the inner side of the T-shaped connecting piece, and fastening sleeves with corresponding internal threads are screwed on the external thread sections. The fastening sleeve is screwed down to tightly extrude the blocking body together with the T-shaped connecting piece, so that the T-shaped connecting piece cannot be easily separated from the fixing hole, and the stability of connection between the cross rod and the supporting column is further enhanced.

Further, the support column is two segmentation telescopic links, and the upside is interior pole, downside and is the outer pole, the fixed block sets up on interior pole, is equipped with positioning mechanism on interior pole and the outer pole. The height of the scaffold is adjusted through telescoping, so that the scaffold is more flexible to apply.

Furthermore, the diagonal of diagonal brace is connected on the support column, 2 diagonal braces are the X type. The function of the diagonal brace is to further enhance the stability between the 4 support columns of the scaffold.

Furthermore, two ends of the diagonal brace are respectively provided with a hook, the inner rod and the outer rod are correspondingly provided with positioning holes, and the hook of the diagonal brace is clamped in the positioning holes. Besides the function of the lapping inclined support rod and the support column, the lapping hook plays a role in positioning the telescopic state of the inner rod and the outer rod, and after the lapping hook is inserted into the positioning hole, the lapping hook is pressed by the inner rod under the action of gravity, so that the lapping hook cannot be easily separated from the positioning hole, and the connection stability is ensured.

Compared with the prior art, the door type scaffold has the advantages that firstly, the connection between the cross rod and the support rod adopts the design of the T-shaped connecting piece and the fastening sleeve, so that the T-shaped connecting piece can be firmly clamped in the fixing hole and cannot fall off, and the safety of operation of an operator on the T-shaped connecting piece is ensured; moreover, the supporting column adopts a telescopic column body, so that the height is adjustable, and the use is more flexible; in addition, the supporting column is further reinforced through the diagonal brace rod, the positioning holes in the inner and outer rods of the hook-engaging supporting column at the two ends of the diagonal brace rod play a role in positioning the telescopic state of the diagonal brace rod, two purposes are achieved at one stroke, the hook-engaging holes can be pressed through the gravity of the inner rod, and the stability of connection between the diagonal brace rod and the supporting column is guaranteed.
