Abstract

The utility model discloses a quick lifting frame which is composed of a U-shaped spider (1), a base (9), an upright post (8), etc. The quick lifting frame is characterized in that the lower end of the upright post (8) is sheathed on the jacket tube (10) of the base (9), and the upper end inserts into a draw rod (4) and is sheathed with a control ring (5). The upper hole of the quick lifting frame is matched with the draw rod, and the lower hole is matched with the upright post. The interior of the quick lifting frame is provided with a couple of locating blocks (6) that is tightly locked by springs (7). The top opening of the draw rod (4) is inserted with an adjusting bolt (2) and a screw nut (3). The utility model has convenient installation and operation, suitable for the ceiling construction of the cement concrete placed in the site of building construction, and for the support of the upper layer part of a scaffold as well as the working facet top and the roofing in a coal mine.

Description

Quick lifting frame

The utility model belongs to building supporting hack lever, but particularly template supports, the stand of the fast lifting of the stand of scaffold with doing.

The support of the scaffold of prior art or cast-in-place system ceiling is generally colligation, and it is slow to add mode construction speeds such as underbed under the column.And the fluid pressure type support that heavy construction is adopted is because complex structure, and involving great expense is difficult for being extensive use of in building.

This practical task provides a kind of fast lifting stand that is used to support construction formwork.The purpose of this utility model reaches like this.With a whole stand of base support, the lower end of column is enclosed within on the sleeve pipe of base, pull bar is inserted in its upper end, and at gate ring of upper port suit, the hole cooperates with the pull bar external diameter on this gate ring, and following hole cooperates with the column external diameter, the a pair of semilune locating piece of assembling in the groove wherein by spring locking, with the suitable for reading middle adjustment screw bolt and nut that cooperates that inserts of pull bar, the upper surface of adjusting bolt is with bolt U type fork again, and gate ring is with screw.Above-mentioned device has promptly been realized the purpose that the utility model proposes.

Description of drawings: Fig. 1 is structure rigging position figure of the present utility model, and Fig. 2 is the component diagram of pull bar, and Fig. 3 is a semilune locating piece component diagram.In the accompanying drawings, 1U type fork, 2 adjust bolt, and 3 adjust nut, 4 pull bars, 5 gate rings, 6 locating pieces, 7 springs, 8 columns, 9 bases, 10 sleeve pipes, 11 gussets, 12 screws, 13 screws, 14 inclined-plane chamfered edges.

Below in conjunction with the embodiment accompanying drawing stand of the present utility model is elaborated.The weight of whole stand is all with base (11) supporting, the weight of bearing when comprising work.Symmetric arrangement gusset (9) is to increase the intensity of base on base.The lower end sleeve of pipe support (8) is contained on the sleeve pipe (10) of base (9), and the upper port of column (8) is inserted pull bar (4), and pull bar also is a hollow section, and its length is not run into sleeve pipe (10) behind the column and is advisable to insert.A gate ring of the upper port suit of column (8) (5), the last oral pore of this ring is outer through cooperating with pull bar, following hole cooperates with the external diameter of column, bosom at gate ring has a groove, symmetry is joined a pair of semilune locating piece (6) by spring (7) locking in groove, with restriction pull bar (4) to bottom offset.The inserting suitable for reading of pull bar (4) is closed and is adjusted bolt (2), and the adjustment nut (3) that cooperates with bolt (2) has a step to cooperate with the external diameter suitable for reading of pull bar.U type fork (1) is fixed on the center, top of adjusting bolt (2) with screw (12).The rotational that U type fork can be determined around screw is to adapt to the needs of different azimuth.Gate ring (5) is fixed on the upper end of column (8) with screw (13).

Some equidirectional inclined-plane chamfered edges (14) to symmetry are arranged on the tube wall of pull bar (4).The right-angle side step of cutting out is in the direction that makes progress of pull bar, notices during installation that right-angle side behind the chamfered edge is last.The position of cutting symmetry 180 degree on the diameter of pipe outer wall are equidirectional.At least a pair of chamfered edge should be arranged in general, but consider the needs of convenience and each lifting altitude of lifting, preferably open a pair of chamfered edge (14) every the 100-150 millimeter.

The garden arc groove that a suitable spring (7) is arranged on the arc limit, garden of semilune locating piece (6) also has an inclined-plane on its straight flange upper edge thickness direction, and the direction of its gradient and size are identical with the gradient of chamfered edge on the pull bar (4).Locating piece (6) is that two relative straight flanges are installed, and locks with spring.The checkpost, right angle of the chamfered edge during work on upper surface and the pull bar (4) is equipped with moving down of restriction pull bar.

During work, fix by shown position, gate ring is good with screw, then pull bar (4) is pulled upwardly to suitable height, put Form beam and can construct.If improper can the rotation of the height that rises adjusted nut (3) fine motion adjusting height to correct position.U type fork can rotate the needs with the Form beam that is fit to different directions.Stand of the present utility model is when needs reduce when highly promptly removing, and turn 90 degrees as long as pull bar (4) revolved, at this moment, semilune locating piece (6) has broken away from the right-angle side of chamfered edge, it is unrestricted that pull bar (4) is gone up, and descends under the effect of deadweight, can reduce to least significant end always.If need to rise once more.Turn 90 degrees as long as pull bar (4) any direction revolved, the process when repeating to begin gets final product.

Stand of the present utility model is suitable for the construction of the cast-in-place cement concrete of ceiling in the building operations most or is used as the last layer of scaffold and fixing stand.Can also be applied to the support on the top, tunnel and the work plane top in colliery.It is simple in structure, and up-down mode is quick, easy, easy operating.Improve the operating efficiency that the cast-in-place concrete mold is made.
