Technical Field

[0001] This invention relates to the field of road and bridge construction technology, specifically to a temporary support for municipal road and bridge construction. Background Technology

[0002] In road and bridge construction, formwork is typically assembled into a fixed shape, and then concrete is poured into it to form that shape. Traditional support systems are complex in structure and cumbersome to use when only temporary support is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a temporary support for the construction of municipal roads and bridges, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a temporary support for municipal road and bridge construction, comprising a plurality of support components and connecting ropes for connecting the support components; the support components include: The outer shell has a rectangular hollow structure, and embedment grooves are provided on both sides of the outer shell; The bottom support rod has an I-shaped structure and can slide inside the outer shell; The upper support mechanism is a telescopic structure, and the upper support mechanism is movably installed in the burial trench; A hinge mechanism is installed in the burial trench, and the bottom support rod is connected to the upper support mechanism through the hinge mechanism; A locking mechanism is provided on both sides of the outer housing, and the locking mechanism is used to lock the bottom support rod; The connecting block has a rectangular structure and is rotatably mounted at one end of the outer shell. A through hole for cooperating with the connecting rope is opened in the middle of the connecting block.

[0005] Preferably, a groove that mates with the upper support mechanism is provided in the embedding groove on one side of the outer shell.

[0006] Preferably, the upper support mechanism includes a support cylinder, a support screw, a rotating block, and a connecting pressure plate. The support cylinder is a hollow structure. The support screw is disposed inside the support cylinder and threadedly connected to the inner wall of the support cylinder. The rotating block is rotatably disposed at one end of the support screw. The connecting pressure plate is hinged to the rotating block.

[0007] Preferably, the hinge mechanism includes a hinge block, a fixed block, two rotating columns, two clamping and limiting components, and a T-shaped connecting block. The hinge block has wedge-shaped protrusions on both sides that cooperate with the clamping and limiting components. The T-shaped connecting block is slidably disposed in a slide groove. The bottom end of the T-shaped connecting block passes through the slide groove and is connected to a bottom support rod located inside the outer housing. The fixed block is connected to the upper surface of the T-shaped connecting block. The two rotating columns are respectively disposed on both sides of the fixed block. The hinge block is rotatably connected to the rotating columns. The rotating columns pass through the hinge block and are connected to the corresponding clamping and limiting components.

[0008] Preferably, the clamping and limiting assembly includes a clamping block, a cavity formed in the clamping groove, a connecting piece, and several springs. The connecting piece is slidably disposed in the cavity. The rotating column passes through the cavity and is connected to the connecting piece. The springs are disposed on both sides of the rotating column, and their two ends are respectively connected to the connecting piece and the inner wall of the cavity.

[0009] Preferably, the locking mechanism includes a pressure plate, a rotating disk, and two rotating shafts. The pressure plate is disposed on the upper side of the rotating disk, and the two rotating shafts are disposed at eccentric positions on both sides of the rotating disk. The rotating disk penetrates the outer housing, and the rotating disk is connected to the outer housing through the rotating shafts.

[0010] Preferably, the support assembly further includes a template, which is connected to the connecting pressure plate by bolts.

[0011] Preferably, the specific usage steps are as follows: 1. Arrange the support components around the template, thread the connecting ropes through the corresponding through holes in sequence, and connect the ends together. At this time, the support components are connected into one unit by the connecting ropes. 2. Pull the support cylinder to one side, and the support cylinder will drive the internal bottom support rod to extend out from the outer shell through the hinge mechanism; 3. Abut the bottom support rod against the corresponding template, then rotate the pressure plate to press and lock the two sides of the bottom support rod by rotating the disc, then lift one end of the support cylinder and rotate the support screw to make it extend out of the support cylinder; 4. Fit the connecting plate with the template. Adjust the extension length of the rotating screw according to the height of the template, thereby adjusting the position of the connecting plate pressing on the template. 5. Repeat steps 2 to 4 to adjust the remaining support components. After all support components have been adjusted, tighten both ends of the connecting rope using a wire rope tensioner to ensure that the connecting rope is taut.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention is provided with connecting ropes. The support components are arranged around the outside of the template that has been formed into a fixed shape. The connecting ropes are used to connect the support components. The connecting ropes are in a taut state, and each support component restricts the other, so that each support component is tightly pressed against the template. 2. The support assembly of the present invention consists of a bottom support rod and an upper support mechanism. The bottom support rod and the upper support mechanism are connected by a hinge mechanism. The bottom support rod and the upper support mechanism support the upper and lower positions of the template, thereby improving the support effect. 3. The present invention also includes a clamping and limiting component. After the support cylinder rotates, it drives the hinge block connected to one end of it to rotate. When the hinge block rotates, it drives the wedge-shaped protrusion to rotate, causing the wedge-shaped protrusion to rotate from one side into the bottom of the clamping block, squeezing the clamping block to move to both sides. The clamping block is gradually pressed against the surface of the groove. Under the obstruction of the clamping block, the hinge block cannot continue to rotate, and the support cylinder cannot continue to rotate, thereby limiting the rotation angle of the support cylinder. In addition, since the clamping block is in close contact with the surface of the groove, the friction between the clamping block and the surface of the groove is used to fix the T-shaped connecting block and prevent it from sliding. Since the T-shaped connecting block is connected to the bottom support rod, it plays an auxiliary role in fixing the bottom support rod. Attached Figure Description

[0021] The hinge mechanism 104 includes a hinge block 1041, a fixed block 1042, two rotating columns 1043, two clamping and limiting components 1044, and a T-shaped connecting block 1045. The hinge block 1041 has wedge-shaped protrusions on both sides that cooperate with the clamping and limiting components 1044. The T-shaped connecting block 1045 is slidably installed in the slide groove 14. The bottom end of the T-shaped connecting block 1045 passes through the slide groove 14 and is connected to the bottom support rod 102 located inside the outer housing 101. The fixed block 1042 is connected to the upper surface of the T-shaped connecting block 1045. The two rotating columns 1043 are respectively installed on both sides of the fixed block 1042. The hinge block 1041 is rotatably connected to the rotating columns 1043. The rotating columns 1043 pass through the hinge block 1041 and are connected to the corresponding clamping and limiting components 1044.

[0022] The clamping and limiting assembly 1044 includes a clamping block 10441, a cavity 10442 formed in a clamping groove, a connecting piece 10443, and several springs 10444. The connecting piece 10443 is slidably installed in the cavity 10442. The rotating column 1043 passes through the cavity 10442 and is connected to the connecting piece 10443. The springs 10444 are installed on both sides of the rotating column 1043, and their two ends are respectively connected to the connecting piece 10443 and the inner wall of the cavity 10442.

[0023] The locking mechanism 105 includes a pressure plate 1051, a rotating disk 1052, and two rotating shafts 1053. The pressure plate 1051 is mounted on the upper side of the rotating disk 1052, and the two rotating shafts 1053 are mounted at eccentric positions on both sides of the rotating disk 1052. The rotating disk 1052 passes through the outer housing 101 and is connected to the outer housing 101 via the rotating shafts 1053. The support assembly 10 also includes a template 15, which is connected to the connecting pressure plate 1034 by bolts.

[0024] The specific usage steps are as follows: 1. Place the support components 10 around the template 15, and thread the connecting ropes 11 through the corresponding through holes 13 in sequence, then connect them end to end. At this time, the support components 10 are connected into one unit by the connecting ropes 11. 2. Pull the support cylinder 1031 to one side, and the support cylinder 1031 drives the internal bottom support rod 102 to extend out from the outer shell 101 through the hinge mechanism 104; 3. Abut the bottom support rod 102 against the corresponding template 15, then rotate the pressure plate 1051, and use the rotating disk 1052 to press and lock the two sides of the bottom support rod 102. Then lift one end of the support cylinder 1031 and rotate the support screw 1032 to make it extend out of the support cylinder 1031. 4. Fit the connecting pressure plate 1034 with the template 15. Adjust the extension length of the rotating screw according to the height of the template 15, and then adjust the position of the connecting pressure plate 1034 pressing on the template 15. 5. Repeat steps 2 to 4 to adjust the remaining support components. After all the support components have been adjusted, tighten both ends of the connecting rope 11 using the wire rope tensioner to ensure that the connecting rope 11 is taut.

[0025] Working principle: In use, such as Figure 4 As shown, at this time, the support components 10 surround the outside of the template 15 that has been formed into a fixed shape, and the support components 10 are connected by the connecting rope 11. The connecting rope 11 is in a taut state, so that each support component 10 is tightly pressed against the template 15. like Figure 5 As shown, at this time, the bottom support rod 102 abuts against the bottom of the template 15, and the upper support mechanism 103 forms an angle with the bottom support rod 102, so that the connecting pressure plate 1034 is located above the bottom support rod 102, thereby achieving two-point support for the template 15. After the support cylinder 1031 rotates, it drives the hinge block 1041 connected to one end to rotate. When the hinge block 1041 rotates, it drives the wedge-shaped protrusion to rotate, so that the wedge-shaped protrusion rotates from one side into the bottom of the pressing block 10441, squeezing the pressing block 10441 to move to both sides. As the rotation angle of the support cylinder 1031 increases, the pressing block 10441 is gradually pressed against the surface of the groove. At this time, the hinge block 1041 cannot continue to rotate under the obstruction of the pressing block 10441, thus playing the role of limiting the rotation angle of the support cylinder 1031. In addition, since the pressing block 10441 is in close contact with the surface of the groove, the friction between the pressing block 10441 and the surface of the groove is used to fix the T-shaped connecting block 1045 and prevent it from sliding. Since the T-shaped connecting block 1045 is connected to the bottom support rod 102, it plays the role of assisting in fixing the bottom support rod 102.
