Description

Technical Field

[0001] The invention relates to the technical field of cable supports, and in particular to a cable pre-buried casing support and a construction method. Background Art

[0002] At present, when burying cables, it is necessary to dig a cable trench in advance, and then install support frames on both sides of the cable trench to support the cables; the existing support frame includes a mounting plate bolted to the side wall of the cable trench, and a plurality of support rods arranged transversely and fixedly connected to the mounting plate, and the cables are laid on the support rods; when construction workers lay cables on this support frame, since the cables need to be first transported to both sides of the cable trench, and then the cables are lowered onto the support rods by the construction workers, but the support rods cannot be moved, resulting in the construction workers needing to first lower the cables to the bottom of the cable trench, and then lift the cables onto the support rods, thereby increasing the labor intensity of the construction workers and making it inconvenient for the construction workers to install the cables; In order to facilitate construction workers to lay cables on support poles, the existing support frame also includes support poles hinged to the mounting plate, and the support poles can rotate along the depth direction of the cable trench. When the construction workers lower the cables, a construction worker in the cable trench is required to push up all the support poles, and then the remaining construction workers lower the cables to the lowest support pole, and then repeat the above operations to lower the cables to the support poles in turn. Although this support frame can facilitate construction workers to install cables, it requires more construction workers to participate in the installation, thereby increasing the construction cost. Summary of the invention

[0003] The invention provides a cable pre-buried casing bracket and a construction method, which can overcome certain defects of the prior art.

[0004] According to the present invention, a cable pre-buried sleeve bracket includes: a bracket body, the bracket body includes a vertically arranged mounting plate, and a horizontally arranged support plate; a plurality of mounting blocks arranged at intervals along the length direction of the mounting plate are arranged on the mounting plate; adjacent mounting blocks and the mounting plate together constitute a mounting interval for one end of the support plate to extend into; circular rotating grooves are provided at both upper and lower ends of the mounting blocks; a rotating block extending into the rotating groove is provided at one end of the support plate extending into the mounting interval.

[0005] According to the present invention, when installing the bracket body, the construction personnel first fix the mounting plate on the side wall of the cable trench by passing the bolts through the bolt holes on the mounting plate, and then the construction personnel insert the mounting blocks on the connecting plate from bottom to top in sequence. Each time the construction personnel installs a mounting block, they need to insert the fixing plate into the third card slot, and then insert the rotating block at the lower end of the support plate into the rotating slot at the upper end of the mounting block. Then repeat the above operations in sequence to assemble the mounting blocks, fixing plates and support plates; after all the mounting blocks, fixing plates and support plates are installed, pass the threaded steel bars through the third through holes on all the mounting blocks; finally, install the connecting piece at the mounting block at the bottom of the mounting plate by bolts to block the rotation groove at the bottom of the mounting block; after the installation is completed, the construction personnel enter the cable trench, push the support plate, and rotate the support plate along the rotation groove, thereby separating the support plate to both sides, thereby expanding the space in the cable trench and facilitating the construction of the construction personnel; compared with the prior art, the support plate separated to both sides does not need to be supported by the construction personnel, thereby reducing the number of construction personnel and facilitating the construction personnel to lay cables; Preferably, the mounting plate is provided with a plurality of connecting plates spaced apart along the length direction of the mounting plate, and the cross-section of the connecting plates is T-shaped; a stopper is provided at the lower end of the connecting plate; a T-slot is provided at the mounting block for the connecting plate to be inserted, and a first slot is provided at the lower end of the T-slot for the stopper to extend into.

[0006] With the present invention, when construction workers assemble the installation block, they only need to align the T-slot on the installation block with the connecting plate on the installation plate, and then insert the connecting plate into the T-slot. When the cable is placed on the support plate, the gravity of the cable presses down the support plate, and the support plate will pull the installation block to tilt toward the support plate due to gravity. At this time, the installation block will be blocked by the connecting plate, thereby preventing the installation block from detaching from the installation plate.

[0007] The stopper blocks the installation block from sliding on the connecting plate due to its own gravity, thereby preventing the installation block from being separated from the connecting plate, making it convenient for construction workers to assemble the installation block.

[0008] Preferably, a plurality of wedge blocks are provided at one end surface of the connecting plate and are spaced apart along the length direction of the connecting plate; and a second slot for the wedge blocks to extend into is provided at the side wall of the T-shaped slot.

[0009] Through the present invention, after the connecting plate is inserted into the T-slot, the wedge block on the connecting plate will extend into the second slot, so that when the support plate pulls the mounting block to tilt toward the support plate due to gravity, the second slot will be blocked by the wedge block to prevent the mounting block from tilting, thereby better improving the structural strength between the mounting block and the connecting plate.

[0010] The end surface of the wedge away from the connecting plate is an inclined surface, so that it is convenient for construction workers to insert the connecting plate into the T-shaped groove.

[0011] Preferably, a first through hole connecting the two rotating grooves is provided at the mounting block, and the first through hole is hexagonal in shape; a second through hole corresponding to the first through hole is provided at the support plate, and the second through hole is hexagonal in shape; a reinforcing rod is provided on one side of the mounting plate, which is arranged along the length direction of the mounting plate and passes through the first through hole and the second through hole, and the cross-section of the reinforcing rod is hexagonal.

[0012] According to the present invention, the reinforcing rod passes through the mounting block and the support plate, and the structural strength of the entire bracket body is enhanced by the reinforcing rod; at the same time, since the reinforcing rod is hexagonal in shape, when the reinforcing rod passes through the support plate, the support plate is prevented from rotating when the cable presses down the support plate.

[0013] Preferably, a third through hole is provided on both sides of the first through hole along the length direction of the mounting block; a connecting rod assembly is provided on one side of the mounting plate, the connecting rod assembly includes two threaded steel bars arranged along the length direction of the mounting plate and passing through the third through hole; connecting plates for connecting the two threaded steel bars are provided at the upper and lower ends of the threaded steel bars, and a fourth through hole for the threaded steel bars to pass through is provided at the connecting plates; the connecting plates are used to block the rotating groove; nuts are provided at the upper and lower ends of the threaded steel bars to cooperate with the threaded steel bars to press the connecting plates against the mounting block.

[0014] Through the present invention, after the connecting rod assembly is installed, the connecting piece limits the reinforcing rod within the first through hole and the second through hole, thereby preventing the reinforcing rod from being separated from the first through hole and the second through hole; at the same time, the reinforcing rod passes through the used mounting blocks, so that all the mounting blocks form a whole, thereby further strengthening the overall structural strength of the bracket body, and preventing the connection between the support plate and the mounting block from breaking due to the gravity of the cable when the support plate supports the cable.

[0015] Preferably, a pressure dividing assembly is provided in the installation interval, and the pressure dividing assembly includes a fixing plate fixedly connected to the installation plate, and a mounting groove is provided at the fixing plate along the length direction of the fixing plate, and the mounting groove is T-shaped; a baffle for blocking the mounting groove is provided at the bottom of the mounting groove; an arched extrusion plate is provided in the installation groove; the extrusion plate includes a limiting portion extending into the installation groove, and a deformation portion cooperating with the support plate; an extrusion portion with a conical cross-section is provided at one end of the support plate extending into the installation interval.

[0016] With the present invention, after the construction workers place the cable on the support plate, the cable presses down the support plate, causing one end of the support plate to squeeze the deformed portion, and the deformed portion is deformed so that the pressure on the deformed portion is dispersed to both sides, thereby preventing the connection between the support plate and the mounting block from being broken due to excessive pressure when the support plate is pressed down due to the excessive weight of the cable; Since the cross section of the extrusion portion is tapered, when the construction workers rotate the support plate, the contact area between the extrusion portion and the deformation portion is small and will not be blocked by the deformation portion, making it difficult for the construction workers to rotate the support plate.

[0017] Preferably, a limiting groove is provided at the deformation portion along the length direction of the extrusion plate, and the extrusion portion extends into the limiting groove.

[0018] With the present invention, when construction workers rotate the support plate to be perpendicular to the mounting plate, the extrusion portion on the support plate will extend into the limiting groove, thereby preventing the support plate from shaking when construction workers place cables, causing difficulty in placing cables.

[0019] Preferably, the support plate is provided with a support groove arranged along the length direction of the support plate.

[0020] With the present invention, construction workers put the cable into the support groove on the support plate, thereby preventing the cable from being separated from the support plate.

[0021] Preferably, a third slot is provided at the mounting plate for the fixing plate to extend into.

[0022] Through the present invention, the third clamping groove and the mounting plate are interference-fitted, thereby preventing the fixing plate from being separated from the mounting plate.

[0023] The present invention provides a cable pre-buried casing construction method, the steps are as follows: S1: Construction workers first transport the cables to both sides of the cable trench; S2: Install the bracket body at the side walls on both sides of the cable trench in a staggered manner. First, connect the mounting plate to the side walls on both sides of the cable trench by bolts. Then, the construction personnel insert the mounting blocks into the connecting plate from bottom to top. Each time the construction personnel install a mounting block, they need to insert the fixing plate into the third slot. Then, insert the rotating block at the lower end of the support plate into the rotating slot at the upper end of the mounting block. Then repeat the above operations in sequence to assemble the mounting blocks, the fixing plates and the supporting plates; after all the mounting blocks, the fixing plates and the supporting plates are installed, the threaded steel bars are passed through the third through holes on all the mounting blocks; finally, the connecting pieces are installed at the mounting blocks at the bottom of the mounting plates by bolts to block the rotation grooves at the bottom of the mounting blocks; S3: After the main body of the bracket is installed, the construction personnel enter the cable trench and cooperate with the lifting machine outside the cable trench to place the cables on the support plate in sequence; S4: After the cable is placed, the construction personnel insert the reinforcing rod into the first through hole and the second through hole, and finally assemble the connecting piece at the mounting block at the uppermost end of the mounting plate to block the rotating groove.

[0024] Through the present invention, bracket bodies of different heights can be set up according to different cable trench depths, thereby adapting to different construction needs; and it is also convenient for construction workers to set up cables. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0038] Example 1 like Figure 1-12 As shown, in this embodiment, a cable pre-buried sleeve bracket is provided, including a bracket body 100, the bracket body 100 includes a vertically arranged mounting plate 110, and a horizontally arranged support plate 130; a plurality of mounting blocks 120 are arranged at intervals along the length direction of the mounting plate 110; adjacent mounting blocks 120 and the mounting plate 110 together constitute a mounting interval 150 for one end of the support plate 130 to extend into; circular rotating grooves 450 are provided at both upper and lower ends of the mounting block 120; a rotating block 520 extending into the rotating groove 450 is provided at one end of the support plate 130 extending into the mounting interval 150.

[0039] According to this embodiment, when installing the bracket body 100, the construction personnel first fix the mounting plate 110 on the side wall of the cable trench by passing the bolts through the bolt holes 210 on the mounting plate 110, and then the construction personnel insert the mounting blocks 120 into the connecting plate 220 from bottom to top. Each time the construction personnel install a mounting block 120, they need to insert the fixing plate 620 into the third slot 230, and then insert the rotating block 520 at the lower end of the support plate 130 into the rotating slot 450 at the upper end of the mounting block 120; Then repeat the above operations in sequence to assemble the mounting block 120, the fixing plate 620 and the support plate 130; after all the mounting blocks 120, the fixing plate 620 and the support plate 130 are installed, the threaded steel bar 930 is passed through the third through hole 410 on all the mounting blocks 120; finally, the connecting piece 920 is installed at the mounting block 120 at the lower end of the mounting plate 110 by bolts to block the rotating groove 450 at the lower end of the mounting block 120; after the installation is completed, the construction personnel enter the cable trench and push the support plate 130 to rotate the support plate 130 along the rotating groove 450, thereby separating the support plate 130 to both sides, thereby expanding the space in the cable trench and facilitating the construction of the construction personnel; compared with the prior art, the support plate 130 separated to both sides does not need to be supported by the construction personnel, thereby reducing the number of construction personnel and facilitating the construction personnel to set up cables; After the construction personnel insert the fixing plate 620 into the third slot 230, the two limiting parts 720 of the extrusion plate 630 are inserted into the installation slot 810, and then the rotating block 520 at one end of the support plate 130 is inserted into the rotating slot 450 at the upper end of the installation block 120. After the construction personnel enter the cable trench and push the support plate 130 perpendicular to the installation plate 110, one end of the support plate 130 will press down the extrusion plate 630, and the deformation part 710 of the extrusion plate 630 will be deformed, and the support plate 130 will be deformed. 0 applies a reaction force, thereby fixing the support plate 130, to prevent the support plate 130 from shaking when the construction workers place the cable, which causes inconvenience to the construction workers; at the same time, after the cable is installed, the cable presses down the support plate 130, causing one end of the support plate 130 to squeeze the deformation part 710, and the deformation part 710 is deformed so that the pressure on the deformation part 710 is dispersed to both sides, thereby preventing the connection between the support plate 130 and the installation block 120 from breaking when the support plate 130 is pressed down due to the excessive weight of the cable; After the installation of the bracket body 100 is completed, the construction personnel enter the cable trench, and then push the support plate 130 in turn to make the support plate 130 perpendicular to the mounting plate 110. Then the construction personnel in the cable trench cooperate with the lifting machine outside the cable trench to place the cables on the support plate 130 in turn; after the cables are placed, the construction personnel insert the reinforcing rod 1101 from the mounting block 120 at the top of the mounting plate 110, through all the first through holes 440 and the second through holes 510 on the mounting blocks 120 and the support plate 130, until the first through hole 510 of the mounting block 120 at the bottom of the mounting plate 110 is inserted into the reinforcing rod 1101. The second through hole 510 is blocked by the connecting piece 920. After the reinforcing rod 1101 is installed, the construction personnel assemble the connecting piece 920 at the mounting block 120 at the uppermost end of the mounting plate 110 to block the rotating groove 450 and limit the reinforcing rod 1101 in the first through hole 440 and the second through hole 510. The reinforcing rod 1101 enhances the overall structural strength of the bracket body 100. At the same time, since the reinforcing rod 1101 is hexagonal in shape, when the reinforcing rod 1101 passes through the support plate 130, the support plate 130 is prevented from rotating when the cable presses down the support plate 130.

[0040] In this embodiment, a plurality of connecting plates 220 are provided at the mounting plate 110 and are arranged at intervals along the length direction of the mounting plate 110, and the cross-section of the connecting plate 220 is T-shaped; a stopper 320 is provided at the lower end of the connecting plate 220; a T-slot 430 for inserting the connecting plate 220 is provided at the mounting block 120, and a first card slot 460 for the stopper 320 to extend into is provided at the lower end of the T-slot 430.

[0041] Through this embodiment, when the construction workers assemble the mounting block 120, the construction workers only need to align the T-slot 430 on the mounting block 120 with the connecting plate 220 on the mounting plate 110, and then insert the connecting plate 220 into the T-slot 430. When the cable is placed on the support plate 130, the gravity of the cable presses down the support plate 130, and the support plate 130 will pull the mounting block 120 due to gravity and have a tendency to tilt toward the support plate 130. At this time, the mounting block 120 will be blocked by the connecting plate 220, thereby preventing the mounting block 120 from being separated from the mounting plate 110.

[0042] The stopper 320 blocks the installation block 120 from sliding on the connecting plate 220 due to its own gravity, thereby preventing the installation block 120 from being separated from the connecting plate 220, making it convenient for construction workers to assemble the installation block 120.

[0043] In this embodiment, a plurality of wedge blocks 310 are disposed at intervals along the length direction of the connecting plate 220 at one end surface of the connecting plate 220 ; a second slot 420 for the wedge blocks 310 to extend into is disposed at the side wall of the T-shaped slot 430 .

[0044] Through this embodiment, after the connecting plate 220 is inserted into the T-slot 430, the wedge block 310 on the connecting plate 220 will extend into the second slot 420, so that when the support plate 130 pulls the mounting block 120 to tilt toward the support plate 130 due to gravity, the second slot 420 will be blocked by the wedge block 310 to prevent the mounting block 120 from tilting, thereby better improving the structural strength between the mounting block 120 and the connecting plate 220.

[0045] One end surface of the wedge block 310 away from the connecting plate 220 is an inclined surface, so that it is convenient for construction workers to insert the connecting plate 220 into the T-shaped groove 430.

[0046] In this embodiment, a first through hole 440 connecting the two rotating grooves 450 is provided at the mounting block 120, and the first through hole 440 is hexagonal in shape; a second through hole 510 corresponding to the first through hole 440 is provided at the support plate 130, and the second through hole 510 is hexagonal in shape; a reinforcing rod 1101 is provided on one side of the mounting plate 110, which is arranged along the length direction of the mounting plate 110 and passes through the first through hole 440 and the second through hole 510, and the cross-section of the reinforcing rod 1101 is hexagonal in shape.

[0047] Through this embodiment, the reinforcing rod 1101 passes through the mounting block 120 and the support plate 130, and the overall structural strength of the bracket body 100 is enhanced by the reinforcing rod 1101; at the same time, since the reinforcing rod 1101 is hexagonal in shape, when the reinforcing rod 1101 passes through the support plate 130, it prevents the support plate 130 from rotating when the cable presses down the support plate 130.

[0048] In this embodiment, third through holes 410 are provided on both sides of the first through hole 440 and are arranged along the length direction of the mounting block 120; a connecting rod assembly 140 is provided on one side of the mounting plate 110, and the connecting rod assembly 140 includes two threaded steel bars 930 that are arranged along the length direction of the mounting plate 110 and pass through the third through hole 410; connecting pieces 920 for connecting the two threaded steel bars 930 are provided at the upper and lower ends of the threaded steel bars 930, and a fourth through hole 1001 for the threaded steel bars 930 to pass through is provided at the connecting piece 920; the connecting piece 920 is used to block the rotating groove 450; nuts 910 that cooperate with the threaded steel bars 930 and press the connecting piece 920 against the mounting block 120 are provided at the upper and lower ends of the threaded steel bars 930.

[0049] Through this embodiment, after the connecting rod assembly 140 is installed, the connecting piece 920 limits the reinforcing rod 1101 in the first through hole 440 and the second through hole 510, thereby preventing the reinforcing rod 1101 from being separated from the first through hole 440 and the second through hole 510; at the same time, the reinforcing rod 1101 passes through the used mounting block 120, so that all the mounting blocks 120 form a whole, thereby further strengthening the overall structural strength of the bracket body 100, and preventing the support plate 130 and the mounting block 120 from breaking due to the gravity of the cable when the support plate 130 supports the cable.

[0050] In this embodiment, a pressure dividing assembly 610 is provided in the installation interval 150, and the pressure dividing assembly 610 includes a fixing plate 620 fixedly connected to the installation plate 110, and a mounting groove 810 is provided at the fixing plate 620 along the length direction of the fixing plate 620, and the mounting groove 810 is T-shaped; a baffle 640 for blocking the mounting groove 810 is provided at the bottom of the mounting groove 810; an arched extrusion plate 630 is provided in the mounting groove 810; the extrusion plate 630 includes a limiting portion 720 extending into the mounting groove 810, and a deformation portion 710 cooperating with the support plate 130; an extrusion portion 530 with a conical cross section is provided at one end of the support plate 130 extending into the installation interval 150.

[0051] Through this embodiment, after the construction personnel place the cable on the support plate 130, the cable presses down the support plate 130, causing one end of the support plate 130 to squeeze the deformation part 710, and the deformation part 710 is deformed so that the pressure on the deformation part 710 is dispersed to both sides, thereby preventing the connection between the support plate 130 and the mounting block 120 from being broken due to excessive pressure when the support plate 130 is pressed down due to excessive weight of the cable; Since the cross section of the extrusion portion 530 is tapered, when the construction personnel rotate the support plate 130 , the contact area between the extrusion portion 530 and the deformation portion 710 is small and will not be blocked by the deformation portion 710 , making it difficult for the construction personnel to rotate the support plate 130 .

[0052] In this embodiment, a limiting groove 730 is provided at the deformation portion 710 and is arranged along the length direction of the extrusion plate 630 , and the extrusion portion 530 is extended into the limiting groove 730 .

[0053] Through this embodiment, when the construction personnel rotate the support plate 130 to be perpendicular to the mounting plate 110, the extrusion portion 530 on the support plate 130 will extend into the limiting groove 730, thereby preventing the support plate 130 from shaking when the construction personnel place the cable, causing difficulty in placing the cable.
