Description

Aluminum alloy template pull rod fixing device

Technical Field

The utility model belongs to the technical field of the building engineering construction, a aluminum alloy template pull rod fixing device is related to.

Background

With the development of aluminum alloy templates and the large application of the aluminum alloy templates in construction projects. The aluminum alloy template has the advantages of light weight, convenient disassembly and smooth and flat surface of the poured concrete. The aluminum alloy template is used, the disassembly is convenient, the transportation cost can be effectively reduced, and the construction period is saved. In the concrete formwork pouring construction. When concrete is poured into the formwork, the concrete is diffused outwards due to gravity, the formwork is easily pushed outwards, and meanwhile, when the concrete is condensed, a certain amount of expansion of the concrete can be generated, so that the formwork expansion phenomenon can be caused. When the concrete formwork is poured, a threaded pull rod device is mostly adopted for fixing the aluminum alloy formwork. The threaded connecting rod is convenient to connect and can tightly fix the aluminum alloy template.

But threaded connecting rods are costly. The connecting rod is required to traverse the whole aluminum alloy formwork pouring area. The amount of fixing screws used is large. After pouring is finished, the screw rod is greatly injected into concrete, and protruding parts at two ends of the screw rod need to be cut off. Two ends of the threaded connecting rod are fixed in a nut screwing mode. When concrete pouring construction is carried out, a large number of aluminum alloy templates are often needed to be used as supports, and threaded connecting rods are used for connection, so that the construction workload is greatly increased.

In view of the defects of the threaded connecting rod in the pouring construction of the aluminum alloy formwork, the threaded connecting rod comprises the following components: 1. when the aluminum alloy templates are spliced, a connection and fixation mode of the threaded pull rod is adopted, a large amount of labor is consumed, the construction operation difficulty is increased, and the engineering period is easily influenced; 2. the threaded pull rod is high in manufacturing cost, the threaded pull rod is disposable, and a large number of threaded pull rods are used to increase the construction cost. The search of relevant documents shows that at present there is no good solution to the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that prior art exists, provide an aluminum alloy template pull rod fixing device that simple structure, the construction degree of difficulty are little, with low costs, the loss is little.

The purpose of the utility model can be realized by the following technical proposal: an aluminum alloy template pull rod fixing device comprises
