Description

Technical Field

[0001] This invention belongs to the field of pipeline installation technology, and specifically relates to a prefabricated pipeline support and pipeline installation method. Background Technology

[0002] Traditional methods for fixing large-diameter air conditioning water, steam, and heat transfer oil pipes in large steel-structured portal frame roof buildings often involve welding to the steel building beams (e.g., Figure 11 (As shown) or by drilling holes to install pipe clamps, although this method can satisfy the need for fixing and reinforcing pipes, drilling and welding will affect the strength of steel building beams, affect the service life of steel structure buildings, and welding pipe clamps on site will result in long construction time, high cost, and significant pollution at the construction site. Summary of the Invention

[0003] The purpose of this invention is to provide a prefabricated pipe support and a pipe installation method to solve the problems mentioned in the background art.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A prefabricated pipe support and pipe installation method includes: an upper channel steel, a lower channel steel, and a covering steel; the upper and lower channel steels are cut from channel steel, and the two sides of the upper and lower channel steels are connected by connecting bolts. When connected, the openings of the upper and lower channel steels are set in opposite directions. The lower channel steel is covered by a U-shaped covering steel, which covers the opening of the lower channel steel and is fixedly connected to the lower channel steel on both sides by bolts or rivets; the upper and lower channel steels, the connecting bolts, and the covering steel constitute a suspension unit. The bottom of the covering steel of each suspension unit is hinged with a main tie rod or a secondary tie rod. A crossbeam of metal beam structure is vertically connected below all the main tie rods or secondary tie rods, and several pipe clamps are installed on the crossbeam through pipe clamp seats.

[0006] Furthermore, the suspension unit is hinged to the main tie rod via a central leveling seat, and the main tie rod is an I-shaped steel structure. The central leveling seat includes: a first seat plate, a deflection plate, a first rotating column, a first rotating groove, a first locking bolt, and a clamping plate. The first seat plate is a plate-shaped structure vertically connected to the bottom of the cladding steel. There are two sets of first seat plates arranged in parallel. Each set of first seat plates has a plate-shaped deflection plate that is rotatably fitted by the first rotating column. There are two sets of deflection plates in total. The bottom of the two sets of deflection plates is connected by a connecting plate. The deflection plate has an arc-shaped groove concentric with the first rotating column to form a first rotating groove. The first seat plate has at least one set of first locking bolts that penetrate the first rotating groove. The position between the first seat plate and the deflection plate can be locked by locking the first locking bolts. Below the connecting plate at the bottom of the two sets of deflection plates, there are two sets of clamping plates perpendicular to the deflection plates. The clamping plates hold and fix the main tie rod.

[0007] Furthermore, the suspension unit is hinged to the auxiliary tie rod via a side-adjusting leveling seat; the auxiliary tie rod is an angle steel structure, and the side-adjusting leveling seat includes: a second seat plate, a second rotating column, a second rotating groove, and a second locking bolt. The second seat plate is a plate-shaped structure vertically connected to the bottom of the cladding steel. There is a set of second seat plates. The auxiliary tie rod of the angle steel structure is rotated and engaged on the second seat plate via the second rotating column. The second seat plate is provided with an arc-shaped groove concentric with the first rotating column to form a second rotating groove. The auxiliary tie rod is provided with at least one set of second locking bolts that penetrate the second rotating groove. The position between the second seat plate and the auxiliary tie rod can be locked by tightening the second locking bolts.

[0008] Furthermore, the pipe clamp is composed of two sets of semi-circular clamps, which are divided into a lower clamp and an upper clamp according to their vertical position. Straight plate structures extend from both sides of the lower clamp and the upper clamp. The lower clamp and the upper clamp are locked and fixed by bolts passing through the straight plate structures on the same side. The lower clamp is fixed to the crossbeam rod by the pipe clamp seat.

[0009] Furthermore, to facilitate the insertion of pipes into the pipe clamp, the line connecting the two straight segments of the lower clamp ring is defined as the ring opening, which is inclined, with the lower side of the ring opening close to the same side of the pipe clamp seat.

[0010] Furthermore, to ensure that the connecting bolt can properly connect the upper and lower channel steels when the steel building beams are not parallel, a pad is provided inside the opening of the upper channel steel, the connecting bolt passes through the pad, and the nut of the connecting bolt is located on the upper surface of the pad. In the same group of suspension units: the lower surface of the pad is in contact with the inner wall of the upper channel steel, and the upper surface of the pad is parallel to the upper surface of the lower channel steel.

[0011] Furthermore, a pipe installation method includes the following steps:

[0012] Step S1, Install the upper and lower channel steel: First, determine whether shims are needed based on the shape of the steel beam. If the upper and lower surfaces of the steel beam are parallel, shims are not needed. If the upper and lower surfaces of the steel beam are not parallel, shims are needed. When installing shims, place them inside the opening of the upper channel steel, ensuring that the upper surface of the shims is parallel to the upper surface of the lower channel steel in the same suspension unit. The width of the upper and lower channel steels is greater than the width of the steel beam. Then, place the upper channel steel above the steel beam and the lower channel steel below the steel beam. The non-opening surfaces of the upper and lower channel steels should be tightly attached to the upper and lower surfaces of the steel beam, respectively. Then, use connecting bolts to lock the upper and lower channel steels in the same suspension unit. Finally, clamp and fix the upper and lower channel steels to the steel beam. If there are shims inside the upper channel steel, drill holes in the shims and lock them in place. Then, cover the lower channel steel with a covering steel.

[0013] Step S2, determine the number of suspension units to be installed: then select whether to install main tie rods based on the number and weight of the pipes to be hung. If the number of pipes is greater than two sets or the weight of the pipes exceeds 40 kg, then install three sets of suspension units; otherwise, only two sets of suspension units need to be installed. The suspension unit consists of upper channel steel, lower channel steel, connecting bolts, and covering steel.

[0014] Step S3: Install the main tie rod or auxiliary tie rod under the suspension unit: When installing three sets of suspension units, the auxiliary tie rod is connected to the underside of the steel covering of the suspension units on both sides through a side leveling seat, and the main tie rod is connected to the underside of the steel covering of the suspension unit in the middle through a middle leveling seat; when installing two sets of suspension units, the auxiliary tie rod is connected to the underside of the steel covering of the two sets of suspension units through a side leveling seat.

[0015] Step S4: Adjust the angles of the tie rod and auxiliary tie rod. Since the crossbeam will be installed horizontally later, and since it needs to be vertically connected to the main tie rod and auxiliary tie rod, adjusting the main tie rod and auxiliary tie rod to a vertical position will allow the crossbeam to be horizontal. During adjustment, use a magnetic level attached to the side wall of the main tie rod and auxiliary tie rod. When adjusting the main tie rod, loosen all the first locking bolts, then rotate the main tie rod, deflection plate, and clamping plate around the first rotating column. At this point, the first locking bolts... The main pull rod slides circumferentially in the rotating groove. After adjusting the main pull rod to vertical according to the level, lock all the first locking bolts to secure the position between the first seat plate and the deflection plate. Then, fix the position of the main pull rod. When adjusting the state of the auxiliary pull rod, loosen the second locking bolt and deflect the auxiliary pull rod around the second rotating column. The second locking bolt slides circumferentially in the second rotating groove. After adjusting the main pull rod to vertical according to the level, lock the second locking bolt to secure the position between the second seat plate and the auxiliary pull rod. Then, adjust the auxiliary pull rod to a vertical state.

[0016] Step S5, Install the crossbeam: Then, use connectors to vertically install the crossbeam onto the auxiliary tie rod and main tie rod that have been adjusted to a vertical position. Use a square for support during installation. When there are three sets of suspension units, the crossbeam is vertically connected below the main tie rod and the two sets of auxiliary tie rods. When there are two sets of suspension units, the crossbeam is vertically connected below the two sets of auxiliary tie rods.

[0017] Step S6, assemble the pipe clamp seat and lower clamp ring: During assembly, the opening of the lower clamp ring is set at an angle, with one side of the opening close to the same side of the pipe clamp seat. The lower clamp ring and clamp seat are installed on the crossbeam using the pipe clamp seat. The number of lower clamp rings and clamp seats is consistent with the number of pipes to be installed.

[0018] Step S7, Install the lower clamp ring and embed it into the pipe: Then install the assembled pipe clamp seat and lower clamp ring on the crossbeam at intervals. Then cover the clamped part of the pipe with rubber and embed it into the lower clamp ring. Because the ring opening of the lower clamp ring is set at an angle, the pipe does not need to be lifted too much to be snapped into the lower clamp ring.

[0019] Step S8, Fix the pipe: Take the upper hoop and wrap it around the pipe, and fix it to both sides of the lower hoop to secure the pipe.

[0020] In summary, the present invention has the following beneficial effects:

[0021] ① Ensuring the stress and stability of steel structures: This prefabricated pipe support is fixed to the lower flange of the steel beam by upper and lower channel steel clamps, eliminating the need for welding and drilling steel beams, thus ensuring the stress and stability of the roof truss steel structure.

[0022] ② High installation efficiency and low cost: This prefabricated pipe support is manufactured entirely in the factory, requiring only splicing and installation on site, effectively reducing time and cost.

[0023] ③ Low pollution: This prefabricated pipe support does not require welding and can be connected and fixed by bolts and anchors. It is simple and easy to operate and causes less pollution on site.

[0024] ④ It can keep the horizontal installation of the crossbeam: Through the establishment of the central leveling seat and the side leveling seat, this prefabricated pipe support is connected to the suspension unit through the central leveling seat and the side leveling seat. Different angles can be adjusted so that the crossbeam under the steel building beam with different inclinations can always keep the pipe horizontal. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Example:

[0039] Please see Figures 1-11 The present invention provides the following technical solution:

[0040] A prefabricated pipe support and pipe installation method includes: an upper channel steel 1, a lower channel steel 2, and a covering steel 3; the upper channel steel 1 and the lower channel steel 2 are cut from channel steel, and the two sides of the upper channel steel 1 and the lower channel steel 2 are connected by connecting bolts 4. When connected, the openings of the upper channel steel 1 and the lower channel steel 2 are set in opposite directions. The lower channel steel 2 is covered by a U-shaped covering steel 3, which covers the opening of the lower channel steel 2 and is fixedly connected to the lower channel steel 2 by bolts or rivets on both sides; the upper channel steel 1, the lower channel steel 2, and the connecting bolts 4 and the covering steel 3 together constitute a suspension unit. The bottom of the covering steel 3 of each suspension unit is hinged with a main tie rod 6 or a secondary tie rod 5. A metal beam structure crossbeam 10 is vertically connected below all the main tie rods 6 or secondary tie rods 5. Several pipe clamps 9 are installed on the crossbeam 10 through pipe clamp seats 12.

[0041] The suspension unit is hinged to the main tie rod 6 via a central leveling seat 7. The main tie rod 6 is an I-shaped steel structure. The central leveling seat 7 includes: a first seat plate 71, a deflection plate 72, a first rotating column 73, a first rotating groove 74, a first locking bolt 75, and a clamping plate 76. The first seat plate 71 is a plate-shaped structure vertically connected to the bottom of the cladding steel 3. There are two sets of first seat plates 71 arranged in parallel. Each set of first seat plates 71 has a plate-shaped deflection plate 72 that is rotatably engaged with the first rotating column 73. There are two sets of deflection plates in total. The bottom of the two sets of deflection plates 72 are connected by a connecting plate. The deflection plates 72 are provided with an arc-shaped groove concentric with the first rotating column 73 to form a first rotating groove 74. The first base plate 71 is provided with at least one set of first locking bolts 75 that pass through the first rotating groove 74. The position between the first base plate 71 and the deflection plates 72 can be locked by locking the first locking bolts 75. Below the connecting plate at the bottom of the two sets of deflection plates 72, there are two sets of clamping plates 76 perpendicular to the deflection plates 72. The clamping plates 76 clamp and fix the main tie rod 6.

[0042] The suspension unit is hinged to the auxiliary tie rod 5 via the side leveling seat 8. The auxiliary tie rod 5 is an angle steel structure. The side leveling seat 8 includes: a second seat plate 81, a second rotating column 82, a second rotating groove 83, and a second locking bolt 84. The second seat plate 81 is a plate-shaped structure vertically connected to the bottom of the covering steel 3. There is a set of second seat plates 81. The auxiliary tie rod 5 of the angle steel structure is rotatably engaged on the second seat plate 81 via the second rotating column 82. The second seat plate 81 is provided with an arc-shaped groove concentric with the first rotating column 73 to form a second rotating groove 83. The auxiliary tie rod 5 is provided with at least one set of second locking bolts 84 that penetrate the second rotating groove 83. The position between the second seat plate 81 and the auxiliary tie rod 5 can be locked by locking the second locking bolts 84.

[0043] The pipe clamp 9 consists of two sets of semi-circular clamps, which are divided into a lower clamp 91 and an upper clamp 92 according to their vertical position. Straight plate structures extend from both sides of the lower clamp 91 and the upper clamp 92. The lower clamp 91 and the upper clamp 92 are locked and fixed by bolts passing through the straight plate structures on the same side. The lower clamp 91 is fixed to the crossbeam 10 by the pipe clamp seat 12.

[0044] The line connecting the two straight segments of the lower hoop 91 is defined as the ring opening 93. The ring opening 93 is inclined, and the lower side of the ring opening 93 is close to the same side of the hoop seat 12.

[0045] A pad 11 is provided inside the opening of the upper channel steel 1. The connecting screw 4 passes through the pad 11. The nut of the connecting screw 4 is located on the upper surface of the pad 11. In the same group of suspension units: the lower surface of the pad 11 is in contact with the inner wall of the upper channel steel 1, and the upper surface of the pad 11 is parallel to the upper surface of the lower channel steel 2.

[0046] Step S1, Install the upper channel steel 1 and the lower channel steel 2: First, determine whether the pads 11 need to be installed based on the shape of the steel building beam 13. If the upper and lower surfaces of the steel building beam 13 are as follows... Figure 1 If the parallel state is shown, then the shim 11 does not need to be installed. If the upper and lower surfaces of the steel building beam 13 are as shown... Figure 5 If the parallel state is shown, a shim 11 needs to be installed. When installing the shim 11, the shim 11 is placed inside the opening of the upper channel steel 1, ensuring that the upper surface of the shim 11 is parallel to the upper surface of the lower channel steel 2 in the same suspension unit. The width of the upper channel steel 1 and the lower channel steel 2 is greater than the width of the steel building beam 13. Then, the upper channel steel 1 is placed above the steel building beam 13 and the lower channel steel 2 is placed below the steel building beam 13. The non-opening surfaces of the upper channel steel 1 and the lower channel steel 2 are respectively pressed against the upper and lower surfaces of the steel building beam 13. Then, the upper channel steel 1 and the lower channel steel 2 in the same suspension unit are locked with connecting screws 4. Then, the upper channel steel 1 and the lower channel steel 2 are clamped and fixed on the steel building beam 13. When there is a shim 11 inside the upper channel steel 1, the shim 11 is drilled and locked. Then, the covering steel 3 is installed on the lower channel steel 2.

[0047] Step S2, determine the number of suspension units to be installed: then select whether to install the main tie rod 6 according to the number and weight of the pipes 14 to be hung. If the number of pipes 14 is greater than two sets or the weight of the pipes 14 exceeds 40 kg, then install three sets of suspension units. Otherwise, only two sets of suspension units need to be installed. The suspension unit is composed of upper channel steel 1, lower channel steel 2 and connecting bolts 4 and covering steel 3.

[0048] Step S3, install the main tie rod 6 or the auxiliary tie rod 5 under the suspension unit: when installing three sets of suspension units (e.g.) Figure 1 As shown), the lower part of the steel covering 3 of the suspension unit on both sides is connected to the auxiliary tie rod 5 via the side leveling seat 8, and the lower part of the steel covering 3 of the suspension unit in the middle is connected to the main tie rod 6 via the middle leveling seat 7; when installing two sets of suspension units (such as... Figure 7 As shown), the two sets of suspension units are connected to the auxiliary tie rod 5 by a side leveling seat 8 below the steel 3 covering the steel.

[0049] Step S4: Adjust the angles of tie rod 6 and auxiliary tie rod 5. Since the crossbeam 10 will be installed horizontally later, and since it needs to be perpendicularly connected to the main tie rod 6 and auxiliary tie rod 5, adjusting the main tie rod 6 and auxiliary tie rod 5 to a vertical position will allow the crossbeam 10 to be horizontal. During adjustment, use a magnetic level (with two vertical axes for observing verticality) attached to the side walls of the main tie rod 6 and auxiliary tie rod 5. When adjusting the main tie rod 6, loosen all the first locking bolts 75, and then rotate the main tie rod 6, deflection plate 72, and clamping plate 76 around the first rotating post 73. At this time, the first locking bolt 75 slides circumferentially in the first rotating groove 74. After adjusting the main pull rod 6 to vertical according to the level, all the first locking bolts 75 are locked, and the position between the first seat plate 71 and the deflection plate 72 is locked. Then the position of the main pull rod 6 is fixed. When adjusting the state of the auxiliary pull rod 5, the second locking bolt 84 is loosened, and the auxiliary pull rod 5 is deflected around the second rotating column 82. The second locking bolt 84 slides circumferentially in the second rotating groove 83. After adjusting the main pull rod 6 to vertical according to the level, the second locking bolt 84 is locked, and the position between the second seat plate 81 and the auxiliary pull rod 5 is locked. Then the auxiliary pull rod 5 is adjusted to a vertical state.

[0050] Step S5, Install the crossbeam 10: Then, use connectors to vertically install the crossbeam 10 onto the auxiliary tie rod 5 and the main tie rod 6, which are adjusted to a vertical state. Use a square for support during installation. When there are three sets of suspension units, the crossbeam 10 is vertically connected below the main tie rod 6 and the two sets of auxiliary tie rods 5. When there are two sets of suspension units, the crossbeam 10 is vertically connected below the two sets of auxiliary tie rods 5.

[0051] Step S6, assemble the pipe clamp seat 12 and the lower clamp ring 91: During assembly, the ring opening 93 of the lower clamp ring 91 is set at an angle, and one side of the ring opening 93 is close to the same side of the pipe clamp seat 12. The lower clamp ring 91 and the clamp seat 12 are installed on the crossbeam 10 using the pipe clamp seat 12. The number of the lower clamp ring 91 and the clamp seat 12 is the same as the number of pipes 14 that need to be installed.

[0052] Step S7, install the lower clamping ring 91 and embed it into the pipe.

[0053] Next, the assembled pipe clamp seat 12 and lower clamp ring 91 are installed on the crossbeam 10 at intervals. Then, the clamped part of the pipe 14 is covered with rubber and embedded in the lower clamp ring 91. Because the ring opening 93 of the lower clamp ring 91 is inclined, the pipe 14 does not need to be lifted too much to be snapped into the lower clamp ring 91.

[0054] Step S8, fix the pipe 14: Take the upper hoop 92 and wrap it around the pipe 14, and fix it to both sides of the lower hoop 91 to secure the pipe 14.

The suspension unit is composed of upper channel steel (1), lower channel steel (2) and connecting screws (4) and covering steel (3) connecting them. Step S3, install the main tie rod (6) or auxiliary tie rod (5) under the suspension unit: When installing three sets of suspension units, the auxiliary tie rod (5) is connected to the underside of the steel covering (3) of the suspension units on both sides through the side leveling seat (8), and the main tie rod (6) is connected to the underside of the steel covering (3) of the suspension unit in the middle through the middle leveling seat (7); When installing two sets of suspension units, the auxiliary tie rod (5) is connected to the underside of the steel covering (3) of the two sets of suspension units through the side leveling seat (8). Step S4, adjust the angles of the tie rod (6) and the auxiliary tie rod (5): Since the crossbeam rod (10) will be installed horizontally later, and since the crossbeam rod (10) will be vertically connected to the main tie rod (6) and the auxiliary tie rod (5), it is only necessary to adjust the main tie rod (6) and the auxiliary tie rod (5) to a vertical state to adjust the crossbeam rod (10) to a horizontal state. When adjusting, use a level with magnetic attraction function to attach it to the side wall of the main tie rod (6) and the auxiliary tie rod (5). When adjusting the state of the main tie rod (6), loosen all the first locking bolts (75), and then deflect the main tie rod (6), the deflection plate (72), and the clamping plate (76) around the first rotating column (73). At this time, the first locking bolts (75) are in Slide the main pull rod (6) in the first rotating groove (74) in a circular motion. After adjusting the main pull rod (6) to vertical according to the display of the level ruler, lock all the first locking bolts (75) to lock the position between the first seat plate (71) and the deflection plate (72). Then fix the position of the main pull rod (6). When adjusting the state of the auxiliary pull rod (5), loosen the second locking bolt (84) and deflect the auxiliary pull rod (5) around the second rotating column (82). The second locking bolt (84) slides in the second rotating groove (83) in a circular motion. After adjusting the main pull rod (6) to vertical according to the display of the level ruler, lock the second locking bolt (84) to lock the position between the second seat plate (81) and the auxiliary pull rod (5). Then adjust the auxiliary pull rod (5) to a vertical state. Step S5, Install the crossbeam (10): Then install the crossbeam (10) vertically on the auxiliary tie rod (5) and the main tie rod (6) that have been adjusted to a vertical state using connectors. Use a square for support during installation. When there are three sets of suspension units, the crossbeam (10) is vertically connected below the main tie rod (6) and the two sets of auxiliary tie rods (5). When there are two sets of suspension units, the crossbeam (10) is vertically connected below the two sets of auxiliary tie rods (5). Step S6, assemble the pipe clamp seat (12) and the lower clamp ring (91): During assembly, the ring opening (93) of the lower clamp ring (91) is set at an angle, and one side of the ring opening (93) is close to the same side of the pipe clamp seat (12). The lower clamp ring (91) and the clamp seat (12) are installed on the crossbeam rod (10) using the pipe clamp seat (12). The number of the lower clamp ring (91) and the clamp seat (12) is consistent with the number of pipes (14) to be installed. Step S7, install the lower clamping ring (91) and embed it into the pipe. Then, install the assembled pipe clamp seat (12) and lower clamp ring (91) on the crossbeam rod (10) at intervals. Then, cover the clamped part of the pipe (14) with rubber skin and embed it in the lower clamp ring (91). Because the ring opening (93) of the lower clamp ring (91) is inclined, the pipe (14) does not need to be lifted too much to be snapped into the lower clamp ring (91). Step S8, fix the pipe (14): Take the upper hoop (92) and wrap the upper hoop (92) around the pipe (14), and fix it on both sides with the lower hoop (91) to clamp and fix the pipe (14).
