Description

Crimper for fixing aluminum formwork and method for fixing aluminum formwork {CRIMPER FOR FIXATION OF ALUMINUM FORMWORKS AND METHOD FOR FIXATION OF THE SAME}

The present invention relates to a crimper and a method for using the same, and more particularly, to a crimper for fixing an aluminum formwork and a method for fixing an aluminum formwork using the crimper.

When performing reinforced concrete (RC) building construction work, the formwork must first be assembled and fixed for subsequent concrete pouring work. When assembling formworks, formworks adjacent to each other must be firmly fixed, thereby avoiding accidents in which formworks collapse during concrete pouring. Therefore, the quality and speed of formwork fixing work affects the quality and construction safety of the entire building structure.

Aluminum (manufacturing) formwork is increasingly used in industry because of its light weight, flat surface, and overlapping use. In the conventional method of fixing aluminum formwork adjacent to each other, a worker strikes a pressing member using a percussion hand tool such as a metal hammer, a wooden hammer, or a dead blow hammer, and fixes it to the fixing member of the adjacent formwork. , secure the two adjacent formwork. However, this method has a disadvantage in that relatively large noise is generated in the process of hitting with a hand tool. Metallic noise from contact with the aluminum formwork can occur, for example when striking with hand tools. Not only does this noise affect workers, but formwork construction may disturb neighbors or violate process noise regulations.

In addition, the hammer face of a conventional hammer (particularly a wooden hammer or a dead blow hammer) is easily damaged due to repeated blows, and the striking tool needs to be replaced. Therefore, workers cannot consistently maintain the quality of formwork fixing work, and even have to temporarily stop construction. In addition, aluminum formwork structures usually use ribs as reinforcing materials, which interfere with the striking operation when fixing adjacent formworks, making it impossible for workers to accurately and effectively strike the pressing member, which affects the work speed.

Considering the disadvantages of the technology of fixing the assembled formwork with the hammer tool strike method, the industry provides a fixing tool for adjacent formworks that is easy for workers to use and has a relatively long service life, so that the formwork fixing work can be done quickly. We need a way to proceed.

Through this, the arm portion including the free end 51' of the press clamping member 50' is moved in the direction of the abutting portion 22' of the support member 20' (ie, moves downward). After the free end 51' of the press clamping member hits the top surface of the pressure pin 9, the pressure pin 9 is sufficiently filled and pressed into the gap 83 of the clamping rod 8, and substantially continuously. Start pushing the pressure pin 9 downward into the gap 83 of the clamping rod 8 until it cannot be inserted downward. The operator completes the work here and removes the crimper 1'. Here, one side edge 91 of the pressing pin 9 is pressed and abuts against the side surface 74 of the side plate portion 72 of the aluminum formwork 7 to fix the adjacent aluminum formworks 7 to each other ( shown in Figure 10).

Similarly, to complete the concrete pouring work and remove all the assembled and fixed aluminum formworks (7), the clamping rods (8) and the pressure pins (9) must first be removed. 17 and 18 show the removal of clamping rods 8 and pressure pins 9 with a crimper 1' from two adjacent formworks 7 in order to subsequently easily remove the aluminum formwork 7. process was shown. Since the pressing pins 9 are all located on one side of one of the two adjacent aluminum formworks 7, the operator can install the assembly structure 60' of the crimper 1' (support member ( 20'), bracket member 30', connecting rod assembly 40' and press clamping member 50') are dismantled from the crimper 1' and replaced with another assembly structure 60'' can do. The structure of each element of the assembly structure 60'' and the structure of each element of the assembly structure 60' (support member 20', bracket member 30', connecting rod assembly 40' and press clamping member) 50') is basically the same, but the axis extending the handle portion 13' shows a left-right mirror image or a symmetrical relationship (as shown in FIG. 17, the support member 20 ", the bracket member 30 The assembly structure 60'' of the crimper 1' including "), the connecting rod assembly 40" and the press clamping member 50" is the assembly structure 60' shown in FIG. 14 and the handle portion (13'), it is easier to perform the operation of removing all the clamping rods 8 and the pressure pins 9.

Based on this, the operator replaces the assembly structure 60' of the crimper 1' with the assembly structure 60" shown in FIG. 17, and then the operator switches the hydraulic switch 111' of the hydraulic mechanism 10'. to position the hydraulic ejector pin 12' at the extended position, and furthermore, the first connecting rod 41 "and the second connecting rod (41") pivotally connected between the two bracket plates (31") of the bracket member (30") 42") to move the free end 51" of the press clamping member 50" connected to the first connecting rod 41' and the second connecting rod 42" away from the abutting portion 22". This maximizes the opening between the free end 51" and the abutment 22".

The operator then uses the crimper 1' rotated 180 degrees and assembles the front surfaces B of the main support platform 21" of the support member 20" of the crimper 1' directly adjacent to each other. abutted on the two front surfaces 75 of the aluminum formwork 7. Here, the upper surface of the abutting portion 22" of the support member 20" abuts on the upper surface of the clamping rod 8, and the side plate portion 72 and the pressing pin 9 of the aluminum formwork 7 adjacent to each other. ) are all located in the receiving notch 23 "of the crimper 1'. Here, as shown in FIG. 17, the free end ( 51'') is located below the lower surface of the pressure pin 9 in the form of an L-shaped structure.

After that, as shown in FIG. 18, the operator operates the hydraulic switch 111' of the crimper 1' to move the hydraulic ejector pin 12' from the extended position toward the retracted position. Through this, the arm portion including the free end 51" of the press clamping member 50" moves toward the abutting portion 22'' of the support member 20''. At this time, the free end 51'' of the press clamping member 50'' hits the lower surface of the pressure pin 9, and pushes the pressure pin 9 upward from the gap 83 of the clamping rod 8. . Through this, the pressure pin 9 moves up and discharges from the clamping state in which the gap 83 of the clamping rod 8 is sufficiently filled, and shows a loose state. Here, the crimper 1' can be removed, and the pressure pin 9 can be removed from the hole 83 of the clamping rod 8 by hand or by other means (as shown in Fig. 19). . After that, the operator extracts the clamping rods 8 from the corresponding through holes 73 of the two adjacent aluminum formworks 7, and removes the adjacent aluminum formworks 7 assembled adjacent to each other, respectively.

Summarizing the above, using the crimper (1) or crimper (1') provided by the present invention, the aluminum formwork 7 is assembled or assembled formwork in a building development or precast factory. When performing the dismantling operation of (7), replace the conventional method of hitting with a metal hammer, wooden hammer, dead blow hammer, etc., and fix the clamping rod or pressure pin for aluminum formwork adjacent to each other used for assembly. It can be used as a blow hand tool to break or loosen. Therefore, since the striking method is no longer used, the noise caused by fixing or disassembling the clamping rod and pressure pin can be effectively reduced. In addition, when fixing the clamping rod and the pressure pin with the crimper 1 or the crimper 1' provided in the present invention, the operator can achieve a relatively uniform fixing force of the pressure pin to the clamping rod compared to the hammer striking method. Therefore, it can reduce the situation of excessive pressure. Accordingly, the work of disassembling the clamping rod and the pressure pin can be performed quickly with less effort. In addition, in the case of ease of construction, using the crimper 1 or crimper 1' provided in the present invention can easily and quickly fix or dismantle the clamping rod and the pressure pin one-time, compared to the conventional striking method. work efficiency can be improved. In addition, the conventional striking method has a defect in that the hammer surface of a metal hammer, a wooden hammer, or a dead blow hammer is worn out and the useful life of the hammer is shortened. However, this phenomenon no longer exists when using the crimper 1 or the crimper 1' provided by the present invention.
