Description

Technical Field

[0001] This utility model belongs to the technical field of segmented cement poles, specifically relating to a galvanized connection structure for segmented cement poles. Background Technology

[0002] A segmented concrete pole is a tower structure composed of multiple concrete pole segments. Each segment is typically cylindrical and ranges in length from several meters to over ten meters. These segments can be assembled together using various connection methods to form a complete concrete pole. Flange connection is a common method for segmented concrete poles. Flanges are installed at the ends of the concrete pole segments, and these flanges have evenly distributed bolt holes. When two segments are connected, the flanges are fastened together with bolts to form a single unit.

[0003] When producing segmented cement poles, the connecting mechanism used to connect the two segments of the cement pole is first connected to the end of the pre-tied steel cage. Then, the steel cage and the connecting structure are placed in a customized mold, and cement mortar is poured into it. After the cement mortar solidifies, the connecting mechanism and the steel cage are firmly formed into a whole cement pole, which makes it easy to splice and assemble to meet different height requirements.

[0004] The connection between the reinforcing cage and the connecting mechanism in the mold and the inner wall of the mold usually has gaps for easy placement. When cement mortar is poured, the mortar liquid can easily flow out, resulting in air holes and uneven mortar filling at the connection point of the reinforcing cage and the connecting mechanism after the cement mortar has solidified. This not only affects the strength of the connecting mechanism of the segmented cement pole after casting, but also affects the appearance of the connecting mechanism due to the mortar liquid flowing out. At the same time, after the mortar solidifies on the connecting structure, the chloride ions in the mortar will damage the passivation film on the metal surface of the connecting structure, causing pitting corrosion and accelerating oxidation, which will affect the segmented cement pole. Utility Model Content

[0005] The purpose of this invention is to provide a galvanized connection structure for segmented cement poles, which can solve the above-mentioned technical problems.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] This utility model provides a galvanized connection structure for segmented cement poles, including connectors and an outer casing disposed on the connectors, wherein the outer casing is used to enclose two symmetrically connected connectors;

[0008] The connector is coated with a galvanized layer. The connector includes a connecting flange and an inner flange. A reinforcing ring is welded between the connecting flange and the inner flange. Multiple reinforcing side plates are welded to the outer circumference of the reinforcing ring at 60° intervals. The connecting flange has multiple bolt holes located between two adjacent reinforcing side plates. A steel ring cylinder is butt-welded to the inner flange. Four reinforcing angle irons are provided on the outer circumference of the steel ring cylinder at 90° intervals. All four reinforcing angle irons are welded to the upper surface of the inner flange.

[0009] A groove is formed on the outer circumferential surface of the inner flange. The width of the groove is set to one-third of the thickness of the inner flange. The width of the groove is set between 4-6 mm, and the depth of the groove is set between 1-3 mm. A cotton rope with a radius in the range of 2-4 mm is matched and placed in the groove.

[0010] Using the aforementioned galvanized connection structure for segmented cement poles, the cotton rope is looped and tightened in the groove. Then, the steel ring cylinder on the connector is sleeved with the end of the reinforcing cage and welded to fix it. The reinforcing cage and connector are then placed in the mold for forming the cement pole, so that the cotton rope is in full contact with the inner wall of the mold to form a seal. Cement mortar is then poured into the mold, so that the cotton rope and the outer periphery of the inner flange form a seal with the cement mortar, preventing liquid from flowing out.

[0011] Preferably, the outer casing includes a first cover plate and a second cover plate, the first cover plate and the second cover plate are configured as symmetrical semicircles, the radius of the semicircle is set to be larger than the radius of the connecting flange and the inner flange, the outer edges of the opposite sides of the first cover plate and the second cover plate are provided with rubber frames, and the opposite sides of the first cover plate and the second cover plate are provided with two sets of inner sleeve plates, each set of inner sleeve plates includes two pieces and corresponds to the two adjacent reinforcing side plates.

[0012] Preferably, the first cover plate and the second cover plate are provided with a movable connection mechanism and a fastening mechanism. The movable connection includes a snap-fit ​​plate provided on one side of the outer peripheral surface of the first cover plate, and a tensioning shaft matching the snap-fit ​​plate provided on one side of the outer peripheral surface of the second cover plate. The two ends of the tensioning shaft are respectively fixed with fixing blocks, and the fixing blocks are fixed on one side of the outer peripheral surface of the second cover plate.

[0013] Preferably, the fastening mechanism includes a rotary push plate disposed on the other side of the outer peripheral surface of the first cover plate, the upper side of the rotary push plate being movably connected to a fixed shaft, two reinforcing plates being fixedly disposed on the other side of the outer peripheral surface of the first cover plate, and a fixed shaft being disposed on the side of the upper reinforcing plate, and a buckle plate matching the rotary push plate being disposed on the other side of the outer peripheral surface of the second cover plate, and a rubber block being adhesively disposed on the inner side of the buckle plate.

[0014] Preferably, a fixing plate is provided on the lower side of the rotary push plate, and a slide rail shaft is provided on the opposite side of the fixing plate and the rotary push plate. A sliding sleeve is slidably provided on the slide rail shaft, and a hand grip shaft is provided on the sliding sleeve. The hand grip shaft matches the slot on the rubber concave plate. The concave plate is provided on the lower reinforcing plate, and a baffle matching the hand grip shaft is provided on the lower reinforcing plate.

[0015] After the two connectors are mated and fixed with bolts, the first and second covers on the outer casing can be snapped into place by the tensioning shaft and the snap-locking plate on the movable connecting mechanism to form a movable connection. Then, the first and second covers are wrapped around the two mating connectors, while the inner sleeve is snapped between the two adjacent reinforcing side plates. Then, the rotating push plate on the fastening mechanism is rotated and pressed against the rubber block on the snap-locking plate, thereby causing the first and second covers to retract together. At the same time, the rotating push plate moves the hand grip shaft to the position corresponding to the baffle and the concave snap-locking plate as it rotates. Then, the hand grip shaft is rotated to form a snap-locking state with the side of the baffle, and the hand grip shaft is also snapped into the slot on the concave snap-locking plate, thereby restricting the hand grip shaft.

[0016] The beneficial effects are:

[0017] 1. This utility model, through the inner flange and groove on the connector, allows a cotton rope to be fitted inside the groove, forming an outer convex ring on the outer circumference of the inner flange. When placed in the mold, the cotton rope on the outer circumference of the inner flange fully contacts the inner wall of the mold. After cement mortar is poured in, the cotton rope seals the gap between the inner flange and the inner wall of the mold, preventing the cement mortar from flowing out. This improves the cement mortar filling effect at the connection between the connecting mechanism and the reinforcing cage, while also keeping the connecting mechanism clean, extending its oxidation resistance time, and improving its rust prevention effect.

[0018] 2. This utility model uses an outer casing to connect the first and second cover plates together via a movable connecting mechanism, sealing the two symmetrically connected connectors. Then, a fastening mechanism merges and fastens the first and second cover plates, thereby fixing the outer casing to the two symmetrically connected connectors. This seals and protects the bolts connecting the two connectors, preventing moisture, acids, and alkalis in the air from oxidizing and corroding the bolts, thus improving the service life of the two connectors after they are connected and fixed.

Detailed Implementation

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figure 1-6 As shown, a galvanized connection structure for segmented cement poles includes a connector 1 and an outer casing 2 disposed on the connector 1. The outer casing 2 is used to enclose two symmetrically connected connectors 1.

[0029] The connector 1 is coated with a galvanized layer. The connector 1 includes a connecting flange 101 and an inner flange 104. A reinforcing ring column 102 is welded between the connecting flange 101 and the inner flange 104. Multiple reinforcing side plates 103 are welded to the outer circumferential surface of the reinforcing ring column 102 at 60° intervals. Multiple bolt holes are formed on the connecting flange 101 between two adjacent reinforcing side plates 103. A steel ring cylinder 105 is butt-welded to the inner flange 104. Four reinforcing angle irons 106 at 90° intervals are provided on the outer circumferential surface of the steel ring cylinder 105. All four reinforcing angle irons 106 are welded to the upper surface of the inner flange 104.

[0030] A groove 107 is formed on the outer circumferential surface of the inner flange 104. The width of the groove 107 is set to one-third of the thickness of the inner flange 104. The width of the groove 107 is set between 4-6mm, and the depth of the groove 107 is set between 1-3mm. A cotton rope with a radius in the range of 2-4mm is matched and installed in the groove 107.

[0031] As an optional implementation, the outer casing 2 includes a first cover plate 201 and a second cover plate 202. The first cover plate 201 and the second cover plate 202 are symmetrical semicircular shapes, and the radius of the semicircle is set to be larger than the radius of the connecting flange 101 and the inner flange 104. Rubber frames 203 are provided on the outer edges of the opposite sides of the first cover plate 201 and the second cover plate 202. Two sets of inner sleeve plates 204 are provided on the opposite sides of the first cover plate 201 and the second cover plate 202. Each set of inner sleeve plates 204 includes two pieces and corresponds to the two adjacent reinforcing side plates 103. With this arrangement, the rubber frames 203 can form a squeezing contact with the outer surfaces of the two connected and formed cement rods, thereby improving the sealing effect of the cavity enclosed by the first cover plate 201 and the second cover plate 202.

[0032] See attached document Figure 3 The first cover plate 201 and the second cover plate 202 are provided with a movable connection mechanism and a fastening mechanism. The movable connection includes a snap-fit ​​plate 208 provided on one side of the outer peripheral surface of the first cover plate 201, and a tensioning shaft 205 provided on one side of the outer peripheral surface of the second cover plate 202 that matches the snap-fit ​​plate 208. The two ends of the tensioning shaft 205 are respectively fixed with fixing blocks, and the fixing blocks are fixed on one side of the outer peripheral surface of the second cover plate 202. A U-shaped plate that fits and matches the tensioning shaft 205 is provided on the side of the snap-fit ​​plate 208 away from the first cover plate 201. In this way, the U-shaped plate and the tensioning shaft 205 can be fitted into each other to form a movable connection, thereby facilitating the movable connection of the first cover plate 201 and the second cover plate 202 together.

[0033] See attached document Figure 4 and attached Figure 5 The fastening mechanism includes a rotary push plate 210 disposed on the other side of the outer peripheral surface of the first cover plate 201. The rotary push plate 210 is configured as an elongated n-shaped shape. The upper side of the rotary push plate 210 is movably connected to the fixed shaft 209. Two reinforcing plates are fixedly disposed on the other side of the outer peripheral surface of the first cover plate 201, and the fixed shaft 209 is disposed on the side of the upper reinforcing plate. A buckle plate 206 matching the rotary push plate 210 is disposed on the other side of the outer peripheral surface of the second cover plate 202. A rubber block 207 is adhered to the inner side of the buckle plate 206. In this way, the rubber block 207 can be used to form a compression buffer on the rotary push plate 210, so that after the first cover plate 201 and the second cover plate 202 are combined, the position of the hand grip shaft 214 does not correspond to the position of the baffle 215, and the rubber block 207 is squeezed to move the hand grip shaft 214 into place.

[0034] See attached document Figure 6 A fixing plate 211 is provided on the lower side of the rotary push plate 210. The fixing plate 211 is L-shaped. A slide rail shaft 212 is provided on the opposite side of the fixing plate 211 and the rotary push plate 210. A sliding sleeve 213 is slidably provided on the slide rail shaft 212. A hand grip shaft 214 is provided on the sliding sleeve 213. The hand grip shaft 214 is matched with the slot on the rubber concave plate 216. The concave plate 216 is provided on the lower reinforcing plate, and a baffle 215 matching the hand grip shaft 214 is provided on the lower reinforcing plate. In this way, the baffle 215 can be used to block and restrict the hand grip shaft 214, and the slot on the concave plate 216 can be used to internally restrict the hand grip shaft 214, so that the hand grip shaft 214 is fixed while being locked, thereby improving the fixing effect of the fastening mechanism after fastening.

[0035] Using the above structure, the cotton rope is looped and tightened in the groove 107. Then, the steel ring cylinder 105 on the connector 1 is connected to the end of the reinforcing cage and welded to fix it. Then, the reinforcing cage and the connector 1 are placed in the mold for forming cement rods, so that the cotton rope is in full contact with the inner wall of the mold to form a seal. Then, cement mortar is poured into it, so that the cotton rope and the outer periphery of the inner flange 104 form a seal with the cement mortar to prevent liquid from flowing out.

[0036] After the two connectors 1 are joined together and fixed with bolts, the first cover plate 201 and the second cover plate 202 on the outer cover 2 can be inserted into the movable connection through the tensioning shaft 205 and the snap-fit ​​plate 208 on the movable connection mechanism. Then, the first cover plate 201 and the second cover plate 202 are wrapped around the two joined connectors 1. At the same time, the inner sleeve plate 204 is snapped between the two adjacent reinforcing side plates 103. Then, the rotating push plate 210 on the fastening mechanism is rotated to abut against the rubber block 207 on the snap-fit ​​plate 206, thereby causing the first cover plate 201 and the second cover plate 202 to merge and retract together. At the same time, the rotating push plate 210 moves the hand grip shaft 214 to the position corresponding to the baffle 215 and the concave snap-fit ​​plate 216 as it rotates. Then, the hand grip shaft 214 is rotated to form a snap-fit ​​state with the side of the baffle 215. At the same time, the hand grip shaft 214 is also snapped into the slot on the concave snap-fit ​​plate 216, thereby restricting the hand grip shaft 214.
