[0003] Existing scaffolding for construction projects cannot be adjusted in size, which limits its use. Existing scaffolding for construction projects can only be used on a single surface, resulting in poor effectiveness. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing construction scaffolding cannot be adjusted in size, has significant limitations in use, and can only be used on a single surface, resulting in poor effectiveness.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a scaffold for construction engineering, comprising two positioning frames and four stepped positioning holes. The four stepped positioning holes are respectively opened on the upper wall of the two positioning frames. The upper wall of the two positioning frames is provided with four sets of limiting holes. Limiting nails are connected to the four sets of limiting holes. Positioning structures are connected to the four stepped positioning holes. Supporting structures are fitted on the outer wall of the positioning structures. Locking structures are connected to the outer wall of the positioning structures.

The positioning structure includes: four threaded positioning rods, four support rods, and eight limiting sleeves. The four threaded positioning rods are respectively connected to the four stepped positioning holes. The four support rods are respectively installed on the upper wall of the four threaded positioning rods. The eight limiting sleeves are respectively fitted on the outer wall of the four support rods.

[0006] As a further embodiment of this utility model: the support structure includes: eight limiting grooves, eight supporting threaded sleeves, and four bidirectional threaded rods; the eight limiting grooves are respectively opened in the eight limiting sleeves, the eight supporting threaded sleeves are respectively connected in the eight limiting grooves, and the two ends of the four bidirectional threaded rods are respectively connected in the eight supporting threaded sleeves.

[0007] As a further embodiment of this utility model: the locking structure includes: four locking nuts, eight supporting threaded holes and eight locking screws; the four locking nuts are respectively fitted onto the outer wall of the four threaded positioning rods, the eight supporting threaded holes are respectively opened on the two end faces of the eight supporting threaded sleeves, and the eight locking screws respectively pass through the eight limiting sleeves and are connected to the eight supporting threaded holes.

[0008] As a further embodiment of this utility model: the auxiliary structure includes: four limiting blocks, four telescopic sleeves and two guide rods; the four limiting blocks are respectively connected to the outer wall surface of the four support rods, the four telescopic sleeves are respectively installed on the inner wall surface of the four limiting blocks, and the two ends of the two guide rods are respectively connected to the inner wall surface of the four telescopic sleeves.

[0009] As a further embodiment of this utility model: the fixing structure includes: four steering support frames, four ground-breaking cones, and four support platforms; the four steering support frames are respectively fitted onto the outer wall surfaces of the two positioning frames, the four ground-breaking cones are respectively fitted onto the outer wall surfaces of the four steering support frames, and the four support platforms are respectively fitted onto the outer wall surfaces of the four steering support frames.

[0012] The present invention adopts the above technical solution and has the following advantages compared with the prior art:

[0013] The eight support threaded sleeves are rotated around the four bidirectional threaded rods to adjust to the appropriate length. Then, the eight support threaded sleeves are inserted into the eight limiting slots. Finally, eight locking screws are passed through the eight limiting sleeves and screwed into the eight support threaded holes. This solves the problem that existing scaffolding used in construction projects cannot be adjusted in size and has great limitations in use.

[0014] If the ground is relatively soft, rotate the four soil-breaking cones around the four steering support frames. The four soil-breaking cones move downward along the four steering support frames and drive into the ground to complete the positioning. If the ground hardness is moderate, rotate the four steering support frames so that the four support platforms face downward. Finally, use limit nails to pass through the corresponding support platforms and drive into the ground to complete the fixation. This solves the problem that existing scaffolding used in construction projects can only be used on a single road surface and has poor effect. Attached Figure Description

[0024] The auxiliary structure includes: four limiting blocks 14, four telescopic sleeves 15, and two guide rods 16; the four limiting blocks 14 are respectively connected to the outer wall surface of the four support rods 6, the four telescopic sleeves 15 are respectively installed on the inner wall surface of the four limiting blocks 14, and the two ends of the two guide rods 16 are respectively connected to the inner wall surface of the four telescopic sleeves 15.

[0025] The fixed structure includes: four steering support frames 17, four ground-breaking cones 18, and four support platforms 19; the four steering support frames 17 are respectively fitted onto the outer wall of the two positioning frames 1, the four ground-breaking cones 18 are respectively fitted onto the outer wall of the four steering support frames 17, and the four support platforms 19 are respectively fitted onto the outer wall of the four steering support frames 17.

[0026] Two guide rods 16 are fitted with return springs 20 on their outer walls. When in use, the operator holds the corresponding two telescopic sleeves 15 and moves them inward along the guide rods 16. The return springs 20 retract. When the other 14 is aligned with the corresponding support rod 6, the operator gradually releases the force, and the return springs 20 reset. The two telescopic sleeves 15 then press the two limit blocks 14 against the two support rods 6.

[0027] The four ground-breaking cones 18 and the four support platforms 19 are respectively connected to the four steering support frames 17 by threads. When in use, the four ground-breaking cones 18 are rotated around the four steering support frames 17, and the four ground-breaking cones 18 move downward along the four steering support frames 17 and are driven into the ground to complete the positioning.

[0028] In Example 1, eight support threaded sleeves 9 are rotated around four bidirectional threaded rods 10 to adjust to a suitable length.

[0029] Specifically, during installation, the operator inserts the four threaded positioning rods 5 into the four stepped positioning holes 2, respectively, and locks them with four locking nuts 11.

The eight support threaded sleeves 9 are then inserted into the eight limiting grooves 8. Next, eight locking screws 13 are passed through the eight limiting sleeves 7 and screwed into the eight support threaded holes 12. Then, one limiting block 14 is clamped onto one side of the support rod 6. The operator holds the corresponding two telescopic sleeves 15 and moves them inward along the guide rod 16.

Finally, the other two limiting blocks 14 are fixed to the corresponding support rods 6 in the same manner to increase the stability of the four support rods 6 and complete the fixing.

The four soil-breaking cones 18 move downward along the four steering support frames 17 and are driven into the ground to complete the positioning. If the ground hardness is moderate, the four steering support frames 17 are rotated so that the four support platforms 19 face downward. Finally, the limiting nails 4 are driven into the ground through the corresponding support platforms 19 to complete the fixation.

[0031] Specifically, during positioning, if the ground is relatively soft, the operator rotates the four steering support frames 17 around the two positioning frames 1 respectively, so that the four soil-breaking cones 18 face downwards.

After that, the four soil-breaking cones 18 are rotated around the four steering support frames 17 respectively, and the four soil-breaking cones 18 move downwards along the four steering support frames 17 and are driven into the ground to complete the positioning. If the ground hardness is moderate, the operator rotates the four steering support frames 17 so that the four support platforms 19 face downwards. Finally, the limiting nails 4 are driven into the ground through the corresponding support platforms 19 to complete the fixing.
