Sloping wedge clamp of building moulding board and mounting, unloading tool thereof

Abstract

The inclined wedged fixture and assembling and disassembling tool for building formwork includes polished rod, inclined wedge and characterized inclined sleeve being one long flat steel pipe with hole in the same axial inclination as that of the inclined wedge. The polished rod is penetrated into the hole of the inclined sleeve, and the inclined wedge is wedged into the interval between the polished rod and the inclined sleeve hole. The present invention has separated fixture and assembling and disassembling tool, the formwork position may be regulated with installing pliers with crank link mechanism, and the fixture may be detached with the inclined wedge. The technology of the present invention is simple and reliable, and has easy assembling and disassembling and low cost.

Description

technical field [0001] The utility model relates to a fixture and a loading and unloading tool for fast loading and unloading of building templates. Background technique [0002] Nowadays, powerful vibrators are used to tamp the concrete on the construction site. Due to the large vibration force, the requirements for the firmness and stability of the formwork are also high. The easiest and most effective method is of course to clamp with a screw rod, as shown in the attached picture Like the left picture of Figure 1, it is a typical example of a rammed concrete wall. The screw rod passes through the two formworks, and the two formworks are kept to the thickness of the concrete wall to be rammed and pressed tightly. When the concrete is rammed, the screw maintains the thickness of the formwork position and withstand the expansion force of the concrete and the vibration force of the vibrator. The screw also has a function to generate a P-direction force by twisting the nut whe...

Problems solved by technology

In addition, the conditions of each construction site are different, and the screws require different lengths, so there are few chances of repeated use.

[0003] The patent closest to the present invention is the patent No. 94213579.2 "Formwork Tie Rod Clamp". In this patent technology, the tie rod and wedge are assembled and disassembled and can be reused. The performance is undoubtedly a big step forward compared with the screw rod, but the biggest disadvantage It does not produce the P-direction adjustment force shown in the left picture of Figure 1. In addition, the structure is also complicated and the cost is high, because each construction site does not use a thousand or several hundred sets, but a few thousand sets at a minimum, and more than ten sets Ten thousand sets is a large equipment investment. In fact, the important disadvantage of this patented technology is that the equipment cost is increased by connecting the loading and unloading tools to the fixture, so it is difficult for users to accept.
