Description

Technical Field

[0001] The utility model relates to the technical field of thin-walled cavity plain concrete arch vibration, in particular to a thin-walled cavity multi-curved plain concrete arch vibration auxiliary device. Background Art

[0002] Thin-walled hollow multi-curved exposed concrete arches are generally designed in a ring shape and are set around the main body of the building, mainly for decoration. The circumference of this concrete structure is relatively long, and it is usually divided into several arc segments for segmented casting.

[0003] When pouring the arch of each segment, the concrete just poured into the arch formwork needs to be vibrated to remove bubbles in the concrete and improve the density of the concrete, so as to ensure the molding quality and effect of the exposed concrete arch. Due to its hollow thin-walled structure, at least two vibrating rods need to be inserted into the inner and outer thin walls of the arch for vibration. However, since the vibrating rods on both sides are difficult to turn and enter the bottom of the arch, the concrete at the bottom of the thin-walled hollow multi-curved exposed concrete arch is difficult to be effectively vibrated, and quality problems such as honeycomb surface and cracks are easily generated after demoulding, and the molding effect is not good.

[0004] To this end, the present application specifically proposes a thin-walled hollow multi-curved plain concrete arch vibration auxiliary device to solve the above technical problems. Utility Model Content

[0005] The main purpose of the utility model is to solve the above-mentioned shortcomings and provide a thin-walled hollow multi-curved plain concrete arch vibration auxiliary device, which can vibrate the concrete at the bottom of the arch during vibration to ensure the molding effect and quality of the arch.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A thin-walled hollow multi-curved plain concrete arch vibration auxiliary device is fixedly arranged on a steel mold at the bottom of the arch, comprising: a mounting plate for mounting a vibration generator; a positioning plate assembly, fixedly arranged on the steel mold at the bottom of the arch, for providing a positioning and mounting platform for the mounting plate; a limiting connection assembly, symmetrically arranged on both sides of the mounting plate, for performing a preliminary limiting connection between the mounting plate and the positioning plate assembly; a connecting locking piece, arranged on the positioning plate assembly, for fixedly connecting the mounting plate and the positioning plate assembly.

[0008] Furthermore, the positioning plate assembly includes a first positioning plate, a plurality of steel bars fixedly arranged on one side of the first positioning plate, a plurality of connecting plates fixedly arranged on the other side of the first positioning plate, and a second positioning plate fixedly arranged on the connecting plates and parallel to the first positioning plate.

[0009] Furthermore, the steel bar is installed between adjacent back ribs of the steel formwork and welded to the back ribs, the length of the steel bar is greater than the spacing between adjacent back ribs, and the width of the first positioning plate in the direction of the steel bar is less than the spacing between adjacent back ribs.

[0010] Furthermore, the connecting locking member includes bolts fixedly arranged at the four corners of the second positioning plate, and through holes opened at positions of the mounting plate corresponding to the bolts.

[0011] Furthermore, the limiting connection assembly includes elastic locking parts symmetrically arranged on both sides of the mounting plate for buckling the edge of the second positioning plate, limiting support plates symmetrically arranged at the upper and lower ends of the second positioning plate, and limiting grooves opened at the upper and lower ends of the mounting plate corresponding to the limiting support plates.

[0012] Furthermore, the elastic locking component includes guide support rods fixedly arranged on both sides of the mounting plate, lock buckles inserted on the guide support rods, fixed blocks fixedly arranged on the mounting plate, and a tension spring with one end fixedly connected to the fixed block and the other end fixedly connected to the lock buckle.

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figure 1-8 As shown, the utility model provides a vibration auxiliary device, which is applied to the vibration construction of thin-walled hollow multi-curved plain concrete arches, and is fixedly arranged on a steel mold at the bottom of the arch, and comprises:

[0028] A mounting plate 1, used for mounting a vibration generator 2;

[0029] The positioning plate assembly 3 is fixedly arranged on the steel mold at the bottom of the arch and is used to provide a positioning and installation platform for the installation plate 1;

[0030] The limiting connection components 4 are symmetrically arranged on both sides of the mounting plate 1 and are used to perform preliminary limiting connection between the mounting plate 1 and the positioning plate component 3;

[0031] The connecting locking member 5 is arranged on the positioning plate assembly 3 and is used for fixing and connecting the mounting plate 1 and the positioning plate assembly 3 .

[0032] When in use, first weld the positioning plate assembly 3 to the steel mold at the bottom of the arch as a mounting platform for the mounting plate 1 on the steel mold, and then fix the vibration generator 2 on the mounting plate 1. At this time, the vibration generator 2 and the mounting plate 1 are taken as a whole, and the initial connection with the positioning plate assembly 3 is achieved with the help of the limiting connection assembly 4. After the initial connection, the whole formed by the mounting plate 1 and the vibration generator 2 will not fall off the positioning plate assembly 3, but the connection between the two is not tight and firm. Its role is to free the operator's hands and facilitate the operator to use the connecting locking piece 5 to further lock the two. After locking the mounting plate 1 and the positioning plate assembly 3, turn on the vibration generator 2 to drive the mounting plate 1 and the positioning plate assembly 3 to vibrate. The positioning plate assembly 3 drives the bottom clear water concrete to vibrate through the steel mold at the bottom of the arch, thereby playing a vibrating role and ensuring the molding effect of the concrete at the bottom of the arch.

[0033] In one embodiment, the positioning plate assembly 3 includes a first positioning plate 31, a plurality of steel bars 32 fixedly arranged on one side of the first positioning plate 31, a plurality of connecting plates 33 fixedly arranged on the other side of the first positioning plate 31, and a second positioning plate 34 fixedly arranged on the connecting plate 33 and parallel to the first positioning plate 31. With this design, the first positioning plate 31 and the second positioning plate 34 are connected by the connecting plate 33 to form a stable whole, and the steel bars 32 serve as a connecting piece between the whole and the steel mold at the bottom of the arch.

[0034] In one embodiment, the steel bars 32 are arranged between adjacent back ribs 6 of the steel formwork and welded to the back ribs 6. The length of the steel bars 32 is greater than the spacing between adjacent back ribs 6. The width of the first positioning plate 31 in the direction of the steel bars 32 is less than the spacing between adjacent back ribs 6. The first positioning plate 31 is fixed to the arch steel formwork by arranging the steel bars 32 on the first positioning plate 31 and welding the steel bars 32 between adjacent back ribs 6. The width of the first positioning plate 31 in the direction of the steel bars 32 is set to be less than the spacing between adjacent back ribs 6 to ensure that the intersection of the steel bars 32 and the back ribs 6 will not be blocked by the first positioning plate 31, so as to facilitate welding of the steel bars 32 to the back ribs 6.

[0035] It is worth explaining that, in the present embodiment, steel bars 32 are used as the connecting piece between the first positioning plate 31 and the back rib 6 instead of directly welding the first positioning plate 31 to the back rib 6. This is because if the first positioning plate 31 is to be welded to the back rib 6, the width of the first positioning plate 31 must be greater than the spacing between adjacent back ribs 6. However, after the first positioning plate 31 is overlapped on the adjacent back rib 6, the intersection of the two is blocked by the first positioning plate 31, which makes welding inconvenient.

[0036] In one embodiment, the connection locking member 5 includes bolts 51 fixedly arranged at the four corners of the second positioning plate 34, and through holes 52 opened at the mounting plate 1 corresponding to the bolts 51. With this design, the through holes 52 on the mounting plate 1 are passed through the bolts 51 on the second positioning plate 34, and nuts are used to lock them, thus completing the fixed connection between the mounting plate 1 and the positioning plate assembly 3, and the connection is reliable and easy to disassemble and assemble.

[0037] In one embodiment, the position-limiting connection assembly 4 includes elastic locking members 41 symmetrically arranged on both sides of the mounting plate 1 for buckling the edge of the second positioning plate 34, position-limiting support plates 42 symmetrically arranged at the upper and lower ends of the second positioning plate 34, and position-limiting grooves 43 opened at the upper and lower ends of the mounting plate 1 corresponding to the position-limiting support plates 42. In the process of passing the through hole 52 on the mounting plate 1 through the bolt 51 on the second positioning plate 34, the elastic locking member 41 buckles the edge of the second positioning plate 34, and the position-limiting support plate 42 is inserted into the position-limiting groove 43. At this time, the mounting plate 1 is prevented from falling off the positioning plate assembly 3, and the operator can loosen both hands to perform the operation of locking the connection locking member 5, without holding the vibration generator 2 and the mounting plate 1 with one hand and installing the nut with the other hand. In addition, the cooperation between the position-limiting support plate 42 and the position-limiting groove 43 can provide certain support for the mounting plate 1, so as to prevent the bolt 51 from being damaged due to excessive shear force applied by the mounting plate 1 during vibration.

[0038] In one embodiment, the elastic locking member 41 includes a guide support rod 411 fixedly arranged on both sides of the mounting plate 1, a lock 412 inserted on the guide support rod 411, a fixing block 413 fixedly arranged on the mounting plate 1, and a tension spring 414 with one end fixedly connected to the fixing block 413 and the other end fixedly connected to the lock 412. With such a design, in the process of passing the through hole 52 on the mounting plate 1 through the bolt 51 on the second positioning plate 34, the hypotenuse of the lock 412 first abuts against the edge of the second positioning plate 34, and gradually moves outward along the direction of the guide support rod 411, at which time the tension spring 414 is stretched until the mounting plate 1 abuts against the second positioning plate 34, the mounting plate 1 and the second positioning plate 34 are both located in the groove of the lock 412, and the tension spring 414 pulls the lock 412 to reset, thereby realizing the buckle connection between the mounting plate 1 and the second positioning plate 34.

[0039] In one embodiment, a handle 7 is fixedly provided on one side of the lock catch 412. With this design, when releasing the elastic locking member 41, the lock catch 412 is pulled outward along the guide support rod 411 by the handle 7, and then the mounting plate 1 is pulled to complete the unlocking.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
