Description

Technical Field

[0001] The utility model relates to the technical field of bridge guardrails, in particular to a bridge guardrail column lock buckle. Background Art

[0002] Bridge guardrails refer to guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going over the bridge. They have the function of preventing vehicles from breaking through, passing under, or climbing over the bridge, as well as beautifying the bridge structure. The selection of the form of bridge guardrails should first be based on the highway grade, taking into account its safety, coordination, the characteristics of the objects to be protected, and the geometric conditions of the site to determine the anti-collision level, and then the structural form should be selected based on its own structure, economy, construction, maintenance and repair factors. There are three ways to embed it: direct embedding of columns, flange connection, and casting the bridge guardrail and bridge deck into one through force-transmitting steel bars. When conditions permit, a pull-out guardrail can be used.

[0003] According to a bridge guardrail column installation lock disclosed in Chinese patent publication number CN220685784U, it includes a lower lock structure that is movably sleeved on an I-beam, and the bridge guardrail column is fixed on the lower lock structure. The lower lock structure includes a connecting plate and vertical plates arranged on both sides of the bottom surface of the connecting plate. Two inclined blocks with opposite inclination directions are arranged side by side below the connecting plate and between the vertical plates on both sides. The inclined blocks include a first inclined block and a second inclined block. The top surfaces of the first inclined block and the second inclined block are both inclined surfaces, and the inclination directions are respectively inclined downward from left to right and inclined downward from right to left. Arc slide grooves are evenly arranged on the inclined surfaces; a fixing rod is arranged between the vertical plates on both sides, and the fixing rod is limited in the arc slide groove. The present application can enhance the stability of structural fixation by setting the opposite first and second inclined blocks, and it is not easy for the fixation to become loose after one side is continuously subjected to force.

[0004] According to the above patent, the first inclined block and the second inclined block are used to tighten the fixed rod to achieve a fixing effect. Since the inclined surfaces of the first inclined block and the second inclined block are provided with multiple arc grooves, and there is a peak point for preventing backoff between two adjacent arc grooves, the fixed rod needs to cross the peak point before entering the corresponding arc groove. Since the peak point is higher than the trough point of the arc groove at the corresponding position, in order to make the fixed rod stuck in the corresponding arc groove, it is necessary to reserve a gap for the fixed rod to cross the peak point. When enough gap is reserved, it will cause the fixed rod to have space to shake when entering the corresponding arc groove, which will seriously affect the installation stability of the bridge guardrail column. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a bridge guardrail column lock so as to solve the technical problems mentioned in the above background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A bridge guardrail column lock comprises a first oblique block, a second oblique block, a vertical plate and a connecting plate, wherein the vertical plates are fixedly connected to the two sides of the bottom of the connecting plate, and the first oblique block and the second oblique block are arranged between the two vertical plates. The first oblique block and the second oblique block are both provided with hook plates for hooking I-beams on both sides of the bottom, and the tops of the first oblique block and the second oblique block are both provided with inclined slopes, and the slopes of the first oblique block and the second oblique block are arranged in opposite directions. A fixing assembly is arranged at the top of the first oblique block and the second oblique block, and a tightening member for tightening the fixing assembly is arranged between the first oblique block and the second oblique block.

[0008] Furthermore, the fixing assembly includes a fixing rod and a rod sleeve, and the two vertical plates located above the first inclined block and the second inclined block are provided with through holes, and the two ends of the fixing rod are respectively inserted into the two through holes, and the outer wall of the fixing rod is provided with a rod sleeve that contacts the first inclined block and the second inclined block.

[0009] Furthermore, the through hole is arranged in a long strip shape along the vertical direction, and the inner side walls of the top and bottom of the through hole are processed with rounded corners.

[0010] Furthermore, the tightening member includes a tightening pin, and positioning slots are provided at the bottom edges of the first inclined block and the second inclined block, and a plurality of semicircular grooves are evenly distributed on the inner bottom wall of the positioning slot, wherein a tightening pin is inserted into a group of overlapping semicircular grooves, and an insertion hole with the same height as the positioning slot is provided on the outer side wall of the vertical plate, and an end of the tightening pin passes through the insertion hole and extends to the outside.

[0011] Furthermore, the positioning slot is kept parallel to the end face of the I-beam, and the bottom tangent lines of the plurality of semicircular grooves are arranged in a colinear manner.

[0012] Furthermore, both side openings of the semicircular groove are processed with bevels, and the diameter of the end of the tightening pin is gradually reduced to form a guiding surface in contact with the bevel.

[0013] In summary, the present invention includes at least one of the following beneficial technical effects:

[0014] 1. The bridge guardrail column lock buckle, by providing a relative inclined surface on the top of the first inclined block and the second inclined block, can use the smooth inclined surface to seamlessly tighten the fixing component, so that after the bridge guardrail column is fixed, no gap that can shake will be generated, thereby improving the fixing stability of the bridge guardrail column, and the arranged fastener can prevent the first inclined block and the second inclined block from loosening, so as to ensure the stability and durability of the bridge guardrail column after being fixed, and further improve the practicality of the bridge guardrail column lock buckle;

[0015] 2. A bridge guardrail column lock buckle, by means of the bevel angle set at the opening of the semicircular groove and the guiding surface of the end of the tightening pin, allows the end of the tightening pin with a smaller diameter to enter the semicircular groove first when the two semicircular grooves are close to overlapping. As the depth of the tightening pin hammered into the semicircular groove increases, the guiding surface of the end of the tightening pin will gradually contact the bevel angle and squeeze the bevel angle, so that the end of the tightening pin is completely drilled into the semicircular groove, thereby fixing the first bevel block and the second bevel block, and completing the final squeezing of the fixing assembly by the first bevel block and the second bevel block, which can reduce the installation difficulty of the bridge guardrail column lock buckle and improve the supporting strength after installation.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1- Figure 5 The utility model discloses a bridge guardrail column lock, comprising a first inclined block 1, a second inclined block 2, a vertical plate 3 and a connecting plate 4, the vertical plates 3 are fixedly connected to the bottom sides of the connecting plate 4, the first inclined block 1 and the second inclined block 2 are arranged between the two vertical plates 3, the bottom sides of the first inclined block 1 and the second inclined block 2 are both provided with hook plates 5 for hooking the I-beam, the tops of the first inclined block 1 and the second inclined block 2 are both provided with inclined slopes 6, the slopes 6 of the first inclined block 1 and the second inclined block 2 are arranged in opposite directions, a fixing component 7 is arranged at the tops of the first inclined block 1 and the second inclined block 2, and a tightening piece 8 for tightening the fixing component 7 is arranged between the first inclined block 1 and the second inclined block 2.

[0026] In this embodiment, by setting the inclined surfaces 6 of the first inclined block 1 and the second inclined block 2, and the inclined surfaces of the first inclined block 1 and the second inclined block 2 are set in opposite directions, when the first inclined block 1 and the second inclined block 2 are struck inward by a hammer, the intersection of the two inclined surfaces 6 will rise, thereby playing the role of squeezing the fixing component 7. The surface of the inclined surface 6 is flat, so that the fixing component 7 can be tightened seamlessly, and there will be no residual movable gap after the fixing component 7 is tightened, which can effectively improve the stability of the bridge guardrail column.

[0027] Due to the setting of the inclined surface 6, the first inclined block 1 and the second inclined block 2 will gradually loosen under pressure. Figure 1 It can be found that a tightening member 8 is provided between the first inclined block 1 and the second inclined block 2. The tightening member 8 is used to lock the positions of the first inclined block 1 and the second inclined block 2 to prevent the first inclined block 1 and the second inclined block 2 from loosening, which can effectively ensure the long-term stability of the bridge guardrail column after installation and effectively improve the practicability of the bridge guardrail column lock.

[0028] Among them, the hook plates 5 of the above-mentioned first oblique block 1 and the second oblique block 2 are the same as the hook plates in Chinese patent publication No. CN220685784U, so the installation method of the first oblique block 1 and the second oblique block 2 and the I-beam is also the same, so the installation method of the first oblique block 1 and the second oblique block 2 and the I-beam will not be elaborated.

[0029] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the fixing assembly 7 includes a fixing rod 71 and a rod sleeve 72, and the two vertical plates 3 located above the first inclined block 1 and the second inclined block 2 are provided with through holes 9, and the two ends of the fixing rod 71 are respectively inserted into the two through holes 9, and the outer wall of the fixing rod 71 is provided with a rod sleeve 72 that contacts the first inclined block 1 and the second inclined block 2.

[0030] In this embodiment, since the first bevel block 1 and the second bevel block 2 are pushed up when they are struck inward by a hammer and move, the fixing assembly 7 will be in contact with the first bevel block 1 and the second bevel block 2, which will cause the fixing rod 71 to rub against the inclined surface 6 and wear. Therefore, a rod sleeve 72 is sleeved on the outer wall of the fixing rod 71, and the rod sleeve 72 is in contact with the inclined surfaces 6 of the first bevel block 1 and the second bevel block 2, so as to prevent the fixing rod 71 from being pushed to rotate by the friction force of the inclined surface 6 and wear, thereby effectively improving the service life of the fixing assembly 7.

[0031] In a further preferred embodiment of the present invention, Figure 5 As shown, the through hole 9 is arranged in a long strip shape along the vertical direction, and the inner side walls of the top and bottom of the through hole 9 are processed with rounded corners 10.

[0032] In this embodiment, by providing the through hole 9 in an elongated strip shape, the fixing rod 71 can be better inserted into the through hole 9, making the installation of the bridge guardrail column more convenient.

[0033] By processing the top and bottom inner walls of the through hole 9 into rounded corners 10, the fixing rod 71 can come into contact with the rounded corners 10 when being squeezed upward by the first inclined block 1 and the second inclined block 2, so that the fixing rod 71 and the through hole 9 have a larger contact surface, thereby increasing the friction force after the fixing rod 71 is tightened, making the installation of the bridge guardrail column more stable.

[0034] In a further preferred embodiment of the present invention, Figure 2 - Figure 4 As shown, the tightening member 8 includes a tightening pin 81, and a positioning slot 82 is provided at the bottom edge of the first inclined block 1 and the second inclined block 2. The inner bottom wall of the positioning slot 82 is evenly distributed with a plurality of semicircular grooves 83, in which a group of overlapping semicircular grooves 83 are inserted with the tightening pin 81, and the outer side wall of the vertical plate 3 is provided with a socket 11 with the same height as the positioning slot 82, and the end of the tightening pin 81 passes through the socket 11 and extends to the outside.

[0035] In this embodiment, when the first inclined block 1 and the second inclined block 2 move upward with the support rod 71, the fixing rod 71 will push the vertical plate 3 and the connecting plate 4 upward, affecting the fixing of the bridge guardrail column. Figure 2 It can be found that positioning slots 82 are provided at the bottom edges of the first inclined block 1 and the second inclined block 2, and at the same time, a socket 11 with the same height as the positioning slot 82 is provided on the outer wall of the vertical plate 3. A tightening pin 81 is passed through the socket 11 and the positioning slot 82 to prevent the vertical plate 3 from moving upward relative to the first inclined block 1 and the second inclined block 2, thereby preventing the fixing rod 71 from pushing the vertical plate 3 upward and affecting the fixation of the bridge guardrail column.

[0036] Since the inclined surfaces 6 of the first inclined block 1 and the second inclined block 2 are smoothly arranged, the first inclined block 1 and the second inclined block 2 will be squeezed by the bridge guardrail column and move away from each other, so that the fixing of the bridge column guardrail is loosened. Figure 2 It can be found that a plurality of semicircular grooves 83 are provided in the positioning slot 82, so that when the tightening pin 81 is inserted into the positioning slot 82, one set of overlapping semicircular grooves 83 will be fixed. At this time, when the first inclined block 1 and the second inclined block 2 are pressed away, they will be restricted by the semicircular grooves 83 and the tightening pin 81 and cannot move, which can effectively ensure the fixing stability of the bridge guardrail column.

[0037] And observe Figure 3 and Figure 4 It can be found that when the first bevel block 1 and the second bevel block 2 are installed from the initial installation to the tightening and fixing component 7, the semicircular grooves 83 located in the positioning slot 82 will gradually approach and overlap, and then after the tightening and fixing component 7, the two adjacent semicircular grooves 83 will be infinitely close to the overlapping state, at this time, the tightening pin 81 is inserted to make the tightening pin 81 squeeze the two semicircular grooves 83, so that the two semicircular grooves 83 completely overlap, and when squeezing the semicircular grooves 83, the first bevel block 1 and the second bevel block 2 will be further relatively close, thereby further enhancing the squeezing of the fixing component 7, which can ensure the firmness of the bridge guardrail column.

[0038] In a further preferred embodiment of the present invention, Figure 2 As shown, the positioning slot 82 is kept parallel to the end surface of the I-beam, and the bottom tangent lines of the plurality of semicircular grooves 83 are arranged in a collinear manner.

[0039] In this embodiment, since the first inclined block 1 and the second inclined block 2 will be relatively close when hit by a hammer, the intersection of the inclined surface 6 will gradually lift and squeeze the fixing component 7 to fix the bridge guardrail column, and a positioning slot 82 is also provided between the first inclined block 1 and the second inclined block 2, into which the same tightening pin 81 needs to be inserted. Therefore, the positioning slot 82 is kept parallel to the end face of the I-beam, so that no matter how the first inclined block 1 and the second inclined block 2 move, the tightening pin 81 can be inserted into the positioning slot 82 of the first inclined block 1 and the second inclined block 2, thereby ensuring the practicability of the bridge guardrail column.

[0040] In a further preferred embodiment of the present invention, Figure 2 and Figure 5 As shown, both side openings of the semicircular groove 83 are processed with bevels 12 , and the diameter of the end of the tightening pin 81 gradually decreases to form a guide surface 13 in contact with the bevel 12 .

[0041] In this embodiment, observe Figure 5It can be found that when the first bevel block 1 and the second bevel block 2 are infinitely close to the tightening and fixing assembly 7, a set of adjacent semicircular grooves 83 will appear to be infinitely close to overlapping but not overlapping, resulting in the tightening pin 81 being unable to be inserted into the two semicircular grooves 83, affecting the fixation of the first bevel block 1 and the second bevel block 2.

[0042] So observe Figure 2 It can be found that a bevel 12 is provided at the opening of the semicircular groove 83, and a guide surface 13 is provided at the end of the tightening pin 81, so that when the two semicircular grooves 83 are close to overlapping, the end of the tightening pin 81 with a smaller diameter can enter the semicircular groove 83 first, and as the depth of the tightening pin 81 being hammered into the semicircular groove 83 increases, the guide surface 13 at the end of the tightening pin 81 will gradually contact the bevel 12 and squeeze the bevel 12, so that the end of the tightening pin 81 is completely drilled into the semicircular groove 83, thereby realizing the fixation of the first bevel block 1 and the second bevel block 2, and completing the final extrusion of the first bevel block 1 and the second bevel block 2 on the fixing component 7, which can reduce the installation difficulty of the bridge guardrail column lock and improve the supporting strength after installation.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
