Description

Technical Field

[0001] The invention relates to the field of auxiliary supporting structures, in particular to an auxiliary supporting structure for construction engineering. Background Art

[0002] Construction engineering refers to the planning, investigation, design, construction, completion and other technical work and completed engineering entities for the construction, reconstruction or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines and equipment. It also refers to the construction of various houses and buildings, also known as construction workload.

[0003] In the prior art, during the construction of foundation pits for building projects, in order to prevent collapse and the like on both sides of the foundation pit and to ensure the safety of the foundation pit construction work, an auxiliary support structure is usually used, through which the soil walls on both sides of the foundation pit are supported inside the foundation pit. However, the auxiliary support structure used for the existing construction project foundation pit construction can generally only support the side walls of the foundation pit of the same width during actual use, and cannot effectively support the side walls of the foundation pit of different widths. At the same time, according to different needs of the foundation pit construction, the side walls of some foundation pits will be inclined. Since the existing auxiliary support structure does not have the function of adjustment, when supporting the foundation pit with an inclined side wall, a gap is easily generated between the support structure and the side wall, which not only reduces the support effect of the foundation pit, but also reduces the applicability of the auxiliary support structure.

The outer side wall of the telescopic plate 18 is also fixedly connected with a symmetrical side plate 21. The spacing between the auxiliary support plates 5 is adjusted by the first adjusting mechanism 3 so that the auxiliary support plates 5 can be tightly attached to the inner side wall of the foundation pit 1 according to the width of the foundation pit 1.

[0033] The auxiliary support plate 5 is movably connected to the side plate 21 through the third rotating rods 24 on both sides of the bottom connecting seat 23;

[0036] like Figure 4 and Figure 5 As shown, a group of left-right symmetrical first fixing plates 8 are fixedly installed on the top surface of the telescopic cylinder 6, and a first rotating hole 9 is opened on the side wall of the first fixing plate 8, and the left and right ends of the bidirectional screw 12 are respectively fixedly installed with first rotating rods 13, and the first rotating rod 13 is movably installed in the first rotating hole 9, and a worm wheel 14 is fixedly installed in the outer center of the bidirectional screw 12 in a set manner, and the worm wheel 14 and the worm 15 are meshed with each other. The worm wheel 14 is driven to rotate by the rotation of the worm 15 and under the meshing action, and the worm wheel 14 will drive the bidirectional screw 12 to rotate, and the first rotating rods 13 at both ends of the bidirectional screw 12 will rotate in the first rotating holes 9 opened on the side wall of the first fixing plate 8;

[0037] like Figure 4 and Figure 5As shown, a group of left-right symmetrical sliding openings 7 are provided on the top surface of the telescopic cylinder 6, and a group of left-right symmetrical telescopic plates 18 are movably installed inside the telescopic cylinder 6, and a sliding block 19 passing through the sliding opening 7 is fixedly installed on the inner side of the top surface of the telescopic plate 18, and a first screw hole 20 is provided on the side wall of the sliding block 19 and is threadedly connected with the bidirectional screw 12 through the first screw hole 20. The sliding block 19 slides in the sliding opening 7 along the bidirectional screw 12 through the sliding block 19 on the side wall through the rotation of the bidirectional screw 12, and thereby drives the symmetrical telescopic plates 18 in the telescopic cylinder 6 to move in opposite directions until the auxiliary support plate 5 is tightly attached to both sides of the inner wall of the foundation pit 1, and plays an auxiliary supporting role for the side wall of the foundation pit 1, which is suitable for effectively supporting the foundation pit 1 when the side wall of the foundation pit 1 is in a vertical state, and can meet the support of the side walls of the foundation pit 1 of different widths;

[0038] like Figure 5 As shown, a side plate 21 is fixedly mounted on the outer side wall of the telescopic plate 18, and a third rotation hole 22 is opened on the front end wall of the side plate 21, and the third rotation hole 22 opened on the side plate 21 of the telescopic plate 18 is used to cooperate with the rotation of the connecting seat 23;

[0039] like Figure 8 As shown, a connecting seat 23 is fixedly installed on the bottom surface of the auxiliary support plate 5, and third rotating rods 24 are fixedly installed on the front and rear ends of the connecting seat 23, respectively. The third rotating rods 24 are movably installed in the third rotating holes 22, wherein the third rotating rods 24 on both sides of the connecting seat 23 on the bottom surface of the auxiliary support plate 5 rotate in the third rotating holes 22 to drive the auxiliary support plate 5 to rotate;

[0040] like Figure 6 As shown, the vertical plate 25 is fixedly mounted on the outer portion of the top surface of the telescopic plate 18, and a vertical opening 26 is provided on the side wall of the vertical plate 25, and fourth rotation holes 27 are provided on the top and bottom surfaces of the vertical plate 25, respectively. The fourth rotation rod 29 rotates in the fourth rotation hole 27 through the vertical opening 26 and the fourth rotation hole 27 provided on the vertical plate 25, and then drives the one-way screw 28 to rotate in the vertical opening 26;

[0041] like Figure 7 and Figure 8 As shown, the upper and lower ends of the one-way screw 28 are respectively fixedly mounted with fourth rotating rods 29, and the fourth rotating rod 29 is movably mounted in the fourth rotating hole 27. A knob 30 is also fixedly mounted on the top of the upper fourth rotating rod 29. After the fourth rotating rod 29 is driven to rotate in the fourth rotating hole 27 by manually rotating the knob 30, the fourth rotating rod 29 will drive the one-way screw 28 to rotate in the vertical opening 26.

[0042] like Figure 7 and Figure 8As shown, the connecting plate 31 is movably installed in the vertical opening 26, and a second screw hole 32 is opened on the top surface of the connecting plate 31 and is threadedly connected with the one-way screw 28 through the second screw hole 32. Concave plates 33 are fixedly installed on the outer wall of the connecting plate 31 and the inner wall of the auxiliary support plate 5, and fifth rotation holes 34 are opened on both sides of the inner wall of the concave plate 33. When the one-way screw 28 rotates, the connecting plate 31 moves upward along the one-way screw 28 through the second screw hole 32, and drives the outer concave plate 33 to move, and cooperates with the fifth rotation hole 34 opened on the concave plate 33 to enable the connecting rod 35 to be tilted;

[0043] like Figure 7 and Figure 8 As shown, fifth rotating rods 36 are fixedly installed on the front and rear sides of the upper and lower ends of the connecting rod 35, and the fifth rotating rod 36 is movably installed in the fifth rotating hole 34. After the concave plate 33 is driven to move by the connecting plate 31, the fifth rotating rods 36 on both sides of the upper and lower ends of the connecting rod 35 will rotate in the fifth rotating hole 34, and the connecting rod 35 will be tilted and the angle formed between the one-way screw 28 will increase, thereby pushing the auxiliary support plate 5 outward, and the auxiliary support plate 5 will be flipped through the third rotating rods 24 on both sides of the bottom end connecting seat 23 until the auxiliary support plate 5 is tightly attached to the inclined side wall in the foundation pit 1, so that the side wall of the foundation pit 1 with different inclinations can be fully supported, avoiding the formation of a gap between the auxiliary support plate 5 and the side wall of the foundation pit 1 to affect the support effect.

[0044] It should be noted that the present invention is an auxiliary support structure for construction engineering. When supporting the side wall of the foundation pit 1 in a vertical state, after the telescopic cylinder 6 is placed on the central part between the side walls on both sides of the foundation pit 1, the hand wheel 17 is rotated to drive the second rotating rod 16 to rotate in the second rotating hole 11 opened on the second fixed plate 10, and the second rotating rod 16 drives the worm 15 to rotate between the second fixed plates 10, and drives the worm wheel 14 to rotate under the meshing action, and the worm wheel 14 will drive the bidirectional screw 12 to rotate, and the first rotating rods 13 at both ends of the bidirectional screw 12 will rotate in the first rotating holes opened on the side walls of the first fixed plate 8. 9, at this time, the sliding block 19 installed on the inner side of the top surface of the telescopic cylinder 6 symmetrically will slide along the bidirectional screw 12 in the sliding opening 7 opened on the top surface of the telescopic cylinder 6 through the first screw hole 20 opened on the side wall, and drive the telescopic plate 18 in the telescopic cylinder 6 to move outward, and the telescopic plates 18 symmetrically will make opposite movement operations until the auxiliary support plates 5 on the outer ends of the telescopic plates 18 are tightly attached to the side walls of the foundation pit 1 on both sides, and the hand wheel 17 can no longer rotate, so that by adjusting the distance between the auxiliary support plates 5, the vertical side walls of the foundation pit 1 of different widths can be effectively supported;

[0045] When supporting the side wall of the foundation pit 1 which is in an inclined state, after adjusting the first adjusting mechanism 3 to make the auxiliary support plate 5 contact with the side wall of the foundation pit 1, since the side wall of the foundation pit 1 is inclined, there will be a gap between the auxiliary support plate 5 and the side wall of the foundation pit 1. At this time, the knob 30 installed on the top surface of the vertical plate 25 at the outer part of the top surface of the telescopic plate 18 is rotated, and the knob 30 will drive the fourth rotating rod 29 at the upper and lower ends of the one-way screw 28 to rotate in the fourth rotating hole 27 opened on the top and bottom surfaces of the vertical plate 25, and the fourth rotating rod 29 will drive the fourth rotating rod 29 to rotate. A fixing plate 8 rotates in the vertical opening 26 opened on the side wall of the vertical plate 25, and makes the connecting plate 31 move upward in the vertical opening 26 along the one-way screw 28 through the second screw hole 32 opened on the top surface, and drives the concave plate 33 installed on the outer wall to move synchronously during the movement. In addition, because the fifth rotating rod 36 installed on both sides of the upper and lower ends of the connecting rod 35 are movably installed in the fifth rotating holes 34 opened on both sides of the inner wall of the concave plate 33 installed on the auxiliary support plate 5 and the connecting plate 31, the fifth rotating rod 36 is When the third rotating rod 24 is rotated in the fifth rotating hole 34, the connecting rod 35 will be tilted between the concave plates 33, and the angle formed by the connecting rod 35 and the one-way screw 28 will gradually increase, and in the process of this change, the auxiliary support plate 5 is pushed outward, and the third rotating rod 24 installed on both sides of the connecting seat 23 on the bottom surface of the auxiliary support plate 5 will rotate in the third rotating hole 22 opened on the side wall of the symmetrical side plate 21 installed on the outer side wall of the telescopic plate 18, and the auxiliary support plate 5 will be tilted. The knob 30 is continuously rotated until the auxiliary support plate 5 is tilted. The auxiliary support plate 5 is tightly attached to the inclined side wall of the foundation pit 1, and after the knob 30 can no longer be rotated, it can fully support the inclined side wall of the foundation pit 1, avoiding the collapse of the side wall of the foundation pit 1 caused by the appearance of a gap between the auxiliary support plate 5 and the foundation pit 1. Therefore, by adjusting the inclination of the auxiliary support plate 5, it is possible to effectively support the side wall of the foundation pit 1 that does not present different inclinations, thereby not only improving the supporting effect of the auxiliary support mechanism 2 on the foundation pit 1, but also improving the applicability of the auxiliary support mechanism 2.
