Description

Technical Field

[0001] The utility model relates to the technical field of column formwork fastening, in particular to a column formwork fastening auxiliary mechanism for civil building construction. Background Art

[0002] Column formwork fasteners are special fixings for column formworks, generally consisting of four pallets connected in the first position, and one end of each pallet is a bent structure. Each pallet is provided with a number of equally spaced long holes along the length direction, and wedge-shaped fixing pins pass through the long holes to fix the pallets, forming a main formwork fastener that is easy to install and disassemble. The column formwork fastener is installed on the column formwork, and the wedge-shaped fixing pin is pushed unidirectionally on the pallet for a certain distance, thereby forming four pallets on the auxiliary bracket to form circumferentially equal fastening forces.

[0003] Currently, when the pallets are connected to each other and pushed in a single direction, it is achieved by pushing the wedge-shaped fixing pin on the one hand and by pushing the bent section of the pallet on the other hand. Both of these pushing methods are single-point pushing and can easily cause the pallet to deflect, causing the fastening force applied to the column form to tilt, resulting in a subsequent adjustment process for the level of the pallet, resulting in reduced installation efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a civil construction column formwork fastening auxiliary mechanism, which solves the problem that a single-point push on a clamping plate easily causes deflection and unbalanced strength of the column formwork.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a civil construction column formwork fastening auxiliary mechanism, comprising a cardboard, the cardboard comprising a strip plate body and a bending plate installed at one end of the strip plate body, a plurality of limit grooves for limiting the distance between the cardboard and the column formwork are opened on the plate body, a plurality of the cardboards overlap to form a frame shape, the plate body with the limit grooves extends outside the frame structure, and a propulsion auxiliary block for propulsing the cardboard to move unidirectionally on the plurality of limit grooves is installed on the cardboard;

[0006] The propulsion auxiliary block includes an end block sliding on the plate body, an insert block for extending and matching with the limit groove is installed at the lower end of the end block, a fitting plate for connecting with the top plate of the bending plate is installed at the upper end of the end block, and a slot matching with the insert block is opened at the upper end of the fitting plate.

[0007] In one embodiment, the end block includes a mounting plate and a push-up assembly plate connected to the mounting plate, the push-up assembly plate, the mounting plate and the rear end surface of the plug block are located on the same vertical plane, the width of the push-up assembly plate is smaller than the width of the mounting plate, and a pushing force area is formed on the top of the mounting plate at the front end of the push-up assembly plate for pushing the end block to move as a whole.

[0008] In one embodiment, the front end surface of the bonding plate and the front end surface of the push-up assembly plate are located on the same vertical plane, and the bonding plate extends backward and the extension length is greater than the structural width of the push-up assembly plate;

[0009] In one embodiment, the opening area of ​​the notch is smaller than the structural area of ​​the plug-in block, and the opening position of the notch is adapted to the installation position of the plug-in block on the installation plate.

[0010] In one embodiment, an arc-shaped groove is provided on the pushing force application area, and a plurality of rubber strips are provided on the arc-shaped groove for increasing the friction with the hand.

[0011] In one embodiment, the longitudinal extension length of the insert block is greater than the opening depth of the limiting groove but not less than the sum of the depths of the limiting groove and the notch.

[0012] Compared with the prior art, the utility model provides a civil construction column formwork fastening auxiliary mechanism, which has the following beneficial effects:

[0013] In the technical solution disclosed by the utility model, by using the setting of the plug block and the slot, combined with the setting of the length of the plug block itself, after penetrating the limit slot, a part of the structure will extend outside the limit slot, and the opening position of the slot is adapted to the position of the plug block, that is, the plug block at the upper end can be positioned through the slot, and the depth of the four plug blocks extending in the slot is used to determine whether the four cardboards are on the same horizontal plane, as long as the four cardboards at the bottom are adjusted and determined to be in a horizontal state. On this basis, even if the stacking does not use external tools, it can also be determined as a horizontal stacking to generate a horizontal tightening force to the column mold to maintain the force balance of the column mold.

[0014] The utility model sets the backward extension length of the bonding plate to be greater than the structural width of the push-up assembly plate, thereby facilitating the connection of the own structure body with the bending section structure, and limiting the horizontal movement of the bending section when subjected to the push-up force by the structural strength of the bonding plate itself and the set shape, and by using the degree of adhesion between the bonding plate and the side wall of the bonding plate, it is possible to directly observe whether the bending section is horizontal after being subjected to the force, which is convenient for correction in the later stage and during operation.

DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] When tightening the column form, the clamping plates 1 are usually pushed in a single direction while being connected to each other. This is achieved by pushing the wedge-shaped fixing pin on the one hand and by pushing the bent section of the clamping plate 1 on the other hand. Both of these pushing methods are single-point pushing and can easily cause the clamping plate 1 to deflect, causing the tightening force of the column form to tilt, resulting in a subsequent adjustment process for the level of the clamping plate 1, resulting in reduced installation efficiency.

[0025] Based on the above existing problems, this solution provides a civil construction column formwork fastening auxiliary mechanism, such as Figure 1-Figure 5 As shown, a card board 1 is provided, and the card board 1 includes a strip plate body 11 and a bending plate 12 installed at one end of the strip plate body 11. When in use, four card boards 1 are provided at a fastening position on a column mold, and the four card boards 1 are connected to each other, such as Figure 1As shown, the plate body 11 is provided with a plurality of limit slots 13 for limiting the distance between the clamping plate 1 and the column mold plate, and a plurality of clamping plates 1 overlap to form a frame to limit the outward expansion of the column mold plate, and the plate body 11 at the position where the limit slots 13 are provided extends outside the frame structure, and the clamping plate 1 is provided with a propulsion auxiliary block 2 for propulsing the clamping plate 1 to move unidirectionally on the plurality of limit slots 13. The length of the plate body 11 extending outward in the bending plate 12 is limited by the combination of the limit slots 13 and the propulsion auxiliary block 2, so that the width of the rectangle surrounded by the four plate bodies 11 is limited by adjusting the extension length of the four plate bodies 11.

[0026] The propulsion auxiliary block 2 includes an end block 21 that slides on the plate body 11, and an insert block 22 for extending and matching with the limit groove 13 is installed at the lower end of the end block 21. A fitting plate 23 for connecting with the top plate of the bending plate 12 is installed at the upper end of the end block 21. A notch 24 matching with the insert block 22 is opened at the upper end of the fitting plate 23. The opening position of the notch 24 is adapted to the installation position of the insert block 22 on the mounting plate 211. The longitudinal extension length of the insert block 22 is greater than the opening depth of the limit groove 13 but not less than the combination of the depth of the limit groove 13 and the notch 24. Therefore, when the end block 21 moves to a suitable position, the insert block 22 extends downward through the limit groove 13. At this time, the insert block 22 The structure extends and passes through the groove, and based on the setting of its own length, part of the structure will be exposed after passing through the limit groove 13. Based on the opening of the groove 24, the plug block 22 located at the upper end can be positioned through the groove 24, and the depth of the four plug blocks 22 extending in the groove 24 is used to judge whether the four card boards 1 are on the same horizontal plane. That is, as long as the four card boards 1 at the bottom are adjusted and determined to be in a horizontal state, the subsequent card boards 1 can be leveled by connecting the plug blocks 22 to the grooves 24. The opening area of ​​the groove 24 is smaller than the structural area of ​​the plug block 22, that is, the groove 24 does not have a limiting function on the plug block 22, and only plays a role in positioning and auxiliary judgment.

[0027] The end block 21 includes a mounting plate 211 and a push-up assembly plate 212 connected to the mounting plate 211. The push-up assembly plate 212, the mounting plate 211 and the rear end surface of the insert block 22 are located on the same vertical plane, so that when the end block 21 is used to push the card board 1, the structure located on the same vertical plane pushes the card board 1, thereby enhancing the force application area of ​​the card board 1. The width of the push-up assembly plate 212 is smaller than the width of the mounting plate 211. The top of the mounting plate 211 at the front end of the push-up assembly plate 212 is formed with a push-up force application area 213 for pushing the end block 21 to move as a whole. An arc groove is provided on the push-up force application area 213, and a plurality of arc grooves are provided on the arc groove for increasing the force application area with the hand. The rubber strip 214 with friction force, the front end surface of the bonding plate 23 and the front end surface of the ejection assembly plate 212 are located on the same vertical plane, thereby reserving more space for the pushing force application area 213, making it convenient to intervene in or withdraw the force in the vertical direction, and the setting of the bonding plate 23 with a rear length greater than the structural width of the ejection assembly plate 212 is convenient to connect the self-structure body with the bending section structure, and the horizontal movement of the bending section when subjected to the ejection force is limited by the structural strength of the bonding plate 23 and the shape of the setting, and the degree of adhesion between the bonding plate 23 and the side wall of the bonding plate 23 can be used to directly observe whether the bending section is horizontal after being subjected to force, which is convenient for correction in the later stage and during operation.
