Detailed Description

The invention will be further elucidated and described with reference to the drawings and embodiments. The utility model discloses in the technical characteristics of each embodiment under the prerequisite that does not conflict each other, all can carry out corresponding combination.

In a preferred embodiment of the present invention, there is provided an external scaffolding wall connecting member for forming a rigid connection structure between a main structure and an external scaffolding, which ensures the safety of erection and construction of the external scaffolding. The main structure used for embedding the fixing piece can be a wall, a column, a beam or other main structures, and is determined according to actual needs.

As shown in fig. 1, the main structure of the external scaffolding wall connecting piece comprises four parts, namely a fixing rod 1, a connecting piece 2, an internal thread piece 3 and a steel pipe 4. The specific structure and connection form of each component will be described in detail below.

The function of dead lever 1 is pre-buried in the major structure thing, provides the drawknot position of outer scaffold frame outward. The fixed rod 1 is formed by connecting a vertical straight rod section and a bending section, and an external thread section is arranged on the straight rod section. It should be noted that, the straight rod section and the bent section may be either integrated or welded in sections, which is not limited in this respect. The effect of steel-pipe fitting 4 is used for carrying out the lock joint with the main node of outer scaffold frame fixedly, and the effect of connecting piece 2 is detachable connection steel-pipe fitting 4 and dead lever 1, wherein can realize fixing and dismantling in order to guarantee steel-pipe fitting 4, still need introduce interior screw thread spare 3 and carry on spacingly.

As shown in fig. 2, the connector 2 is provided with a through hole and a blank region as a welding region for welding the end of the steel pipe 4. The connecting piece 2 is sleeved on the external thread section of the straight rod section through a through hole arranged at the upper part. The internal thread piece 3 can be screwed into the external thread section and is closely attached to the connecting piece 2 sleeved on the same external thread section to form unilateral limit to the connecting piece 2. In order to ensure the limiting effect, the size of the internal thread member 3 should be larger than the size of the through hole formed on the connecting member 2. In addition, the other surface of the connector 2 needs to be supported to form another limit position on the main structure, except for the surface welded to the steel pipe 4. Since one end of the steel pipe 4 is welded and fixed to the welding region of the connector 2, the steel pipe 4 can be rigidly fixed to the main structure under the double-side restriction of the female screw 3 and the main structure to the connector 2. The other end of the steel pipe fitting 4 extends and overhangs in the direction far away from the fixing rod 1 and is used for connecting and fixing a main node of an external scaffold. When in actual use, can be in advance steel pipe fitting 4 and connecting piece 2 through welding be even as an organic whole, directly overlap connecting piece 2 on pre-buried dead lever 1 during the installation, rethread internal thread spare 3 with connecting piece 2 compress tightly on dead lever 1 can.

The concrete size parameters and the materials of the fixing rod 1, the connecting piece 2, the internal thread piece 3 and the steel pipe piece 4 in each outer scaffold wall connecting piece can be selected according to actual needs. In this embodiment, the fixing rod 1 is an L-shaped screw, the connecting member 2 is a steel plate with an opening, and the internal thread member 3 is a nut with an internal thread. The L-shaped screw, the steel plate and the nut all belong to common standard parts in construction, and special processing is not needed, so that the acquisition and processing cost of raw materials can be reduced. In addition, the thread parameters of the external thread section on the straight rod section of the L-shaped screw need to be matched with the nut so that the two can form thread matching. The width of the steel plate should be larger than the diameter of the welded steel pipe 4, and the length should be enough to allow a space for opening a through hole. The nut is screwed on the external thread section of the L-shaped screw and tightly presses the back of the steel plate, and the size of the nut is larger than the through hole formed in the waist of the steel plate. Through the rotation of the nut on the external thread section, the distance between the bending sections of the steel plate and the L-shaped screw rod can be adjusted, and then the steel pipe fitting 4 is fixed on the connecting piece 3. However, the L-shaped screw, the steel plate and the nut are only one implementation form of the middle fixing rod 1, the connecting member 2 and the internal thread member 3, and other alternatives can be adopted in other embodiments instead of the middle fixing rod, as long as similar functions can be realized.

In addition, in the connecting element 2, the aperture of the through hole should preferably be slightly larger than the diameter of the straight rod section of the fixing rod 1, that is, the connecting element 2 and the fixing rod 1 form a clearance fit, so that the connecting element 2 can only slide along the axial direction of the straight rod section and can not move along the radial direction, thereby improving the stability of connection and fixation between the two.

The length of the steel pipe 4 is determined according to the actual distance between the scaffold and the main structure, and since the steel pipe 4 is generally horizontally erected, the length of the steel pipe 4 should be longer than the span between the external scaffold wall coupling and the external scaffold main node. Of course, in practical applications, the steel pipe 4 may not be horizontal, and may also have a certain inclination angle, which is not limited.

This outer scaffold wall connecting piece is in the assembly use, and specific use method is as follows:

one end of the steel pipe 4 is placed at the lower part of the steel plate of the connecting piece 2 and is welded firmly by adopting a welding mode. Then embedding the bent section of the L-shaped screw into the main structure and connecting and fixing the bent section with the built-in steel bar, wherein the straight rod section is positioned outside the pouring area of the main structure, and the external thread section on the straight rod section needs to be ensured to protrude out of a side vertical face of the main structure, on which an external scaffold needs to be erected; and then after the concrete is cured, starting to set up an external scaffold, for each position of the external scaffold needing to be tied, penetrating the through hole of the connecting piece 2 into the external thread section of the fixing piece 1 and attaching the external thread section to the side surface of the main structure, and then screwing the nut so that pressing force is applied between the connecting piece 2 and the main structure, and the connecting piece and the main structure are matched with each other to be clamped and fixed on the fixing piece 1 under the limit of the steel plate. The other end of the steel pipe fitting 4 extends to the main node of the outer scaffold and is connected with the main node of the outer scaffold through a fastener.

As shown in fig. 3, in an actual construction organization, material is first purchased and entered; then, draw the node position to the first even wall, get a set of even wall spare device and install, draw the node position to every other even wall in proper order and get a set of even wall spare device and install, wait at last when the construction finishes dismantling the outer scaffolding, unscrew the nut on each L type screw rod, and then lift off steel pipe fitting 4 and connecting piece 2 and be used for the used repeatedly when the construction next time. After the construction is completed and the connector 2, the nut, and the steel pipe 4 are removed, the portion of the L-shaped screw, from which the main structure is exposed, is cut off, and then other necessary constructions can be continued on the main structure.

The above-mentioned embodiments are merely a preferred embodiment of the present invention, but it is not intended to limit the present invention. Various changes and modifications can be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present invention. Therefore, all the technical schemes obtained by adopting the mode of equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
