[0025] As Figures 1 - 4 shown:
[0026] A length-adjustable connecting piece for formwork engineering construction, made of metal material; used for connecting two adjacent and parallel support back braces 10 under the formwork, slidably installed on the two support back braces 10 and fixedly connected after sliding to a specified position along the length direction of the support back braces 10; the length-adjustable connecting piece includes a telescopic section 1 connected to one of the support back braces 10 at one end, a fixed section 2 connected to and slidably matched with the telescopic section 1, and a locking assembly 3 for locking the telescopic section 1 and the fixed section 2; the top surfaces of the telescopic section 1 and the fixed section 2 are in the same plane, and the other end of the fixed section 2 is connected to the other support back brace 10; the support back brace 10 is a rectangular pipe or a steel pipe.
[0027] During use, install the support back brace 10 on the top bracket above the vertical pole. After all the support back braces 10 are installed, install the length-adjustable connecting piece on two adjacent support back braces 10, and adjust the positions of the adjacent length-adjustable connecting pieces according to the position and size of the formwork; so that it can effectively support and fix the formwork and bear the force evenly.
[0028] Since it is made of metal materials, it has higher strength than wooden beams and is not easily damaged; thus, it can effectively achieve multiple turnovers, reducing construction costs; its high strength enables less usage, thereby accelerating the construction progress and improving construction efficiency.
[0029] Since the utility model is installed on the support back rib 10, during the installation process of the formwork, the length adjustment connecting piece will not move under the external force of construction equipment and construction personnel, causing uneven support for the formwork.
[0030] When in use, first adjust the positional relationship between the telescopic section 1 and the fixed section 2 according to the distance between the two groups of support back ribs 10, then fix the fixed section 2 on one group of support back ribs 10, then axially move the telescopic section 1 to finely adjust their positions, and then use the locking assembly 3 to lock and fix the two;
[0031] When installing the length adjustment connecting piece, it can be moved along the length direction of the support back rib 10 as needed, and after it moves to the designated position, it is fixed to the support back rib 10.
[0032] In some possible implementation manners, the telescopic section 1 includes a first connecting piece 12 connected to the support back rib 10 and an outer sleeve 11 connected to the side of the first connecting piece 12 away from the support back rib 10.
[0033] In some possible implementation manners, the fixed section 2 includes a second connecting piece 22 connected to the other group of support back ribs 10 and an inner sleeve 21 connected to the side of the second connecting piece 22 close to the first connecting piece 12; the inner sleeve 21 is coaxially sleeved inside the outer sleeve 11 and is in telescopic sliding fit with the outer sleeve 11.
[0034] In some possible implementation manners, the first connecting piece 12 and the second connecting piece 22 have the same structure, presenting a U-shaped structure with the opening facing downwards; the top surfaces of the first connecting piece 12, the outer sleeve 11, and the second connecting piece 22 are on the same plane.
[0035] The outer sleeve 11 and the inner sleeve 21 are coaxially arranged, and the outer sleeve 11 is sleeved outside the inner sleeve 21; telescoping is achieved through their sliding, thereby realizing the connection of two adjacent groups of support back ribs 10 at different distances;
[0036] After the length adjustment of the telescopic section 1 and the fixed section 2 is in place, first insert the first connecting piece 12 and the second connecting piece 22 respectively onto the corresponding support back ribs 10 through the U-shaped structure with the opening facing downwards;
[0037] Subsequently, the locking assembly 3 is used to fix the two; after the two form a stable overall structure, the overall structure can be moved along the length direction of the supporting back rib 10 to move it to the specified position, and then the first connecting member 12 and the second connecting member 22 are fixedly connected to the supporting back rib 10;
[0038] In some possible embodiments, the locking assembly 3 includes a long slot 31 provided on the outer sleeve 11 and arranged along the axis of the outer sleeve 11, a through hole provided on the inner sleeve 21 and corresponding to the long slot 31, and a locking bolt 32 used in cooperation with the long slot 31 and the through hole; the long slots 31 are in two groups and are symmetrically arranged along the axis of the outer sleeve 11; the two groups of long slots 31 are respectively arranged on two side surfaces of the outer sleeve 11 along its axis; the through holes are in two groups and are symmetrically arranged along the axis of the inner sleeve 21, and the two groups of long slots 31 are respectively arranged on two side surfaces of the inner sleeve 21 along its axis and correspond to the long slots 31.
[0039] The long slots 31 and the through holes are arranged in two groups along the axis direction of the outer sleeve 11. The through holes and the long slots 31 will communicate, and their axes will be on a horizontal plane; when telescoping, the telescopic section 1 moves, driving the through hole to move. When the telescopic section 1 moves to the specified position, one end of the locking bolt 32 will sequentially pass through the long slot 31, the through hole, the through hole, and the long bar, and cooperate with the nut to realize the locking of the telescopic section 1 and the fixed section 2;
[0040] In some possible embodiments, the locking assembly 3 further includes a tooth groove 33 provided on the outer sleeve 11 and arranged on the same side as the long slot 31, and a tooth plate 34 sleeved outside the locking bolt 32 and used in cooperation with the tooth groove 33; the tooth grooves 33 are in multiple groups and are arranged along the length direction of the outer sleeve 11.
[0041] The arrangement of the tooth groove 33 and the tooth plate 34 will further strengthen the connection between the telescopic section 1 and the fixed section 2, and prevent the telescopic section 1 and the fixed section 2 from shifting under the action of external force; the tooth plate 34 is sleeved outside the locking bolt 32 and meshes with the tooth groove 33, and the cooperation between the tooth plate 34 and the tooth groove 33 will further limit the movement of the telescopic section 1 and the fixed section 2 after locking.
