Description

Technical Field

[0001] The utility model relates to the technical field of building civil engineering structure quality and construction, in particular to an auxiliary tool for concrete plane film covering. Background Art

[0002] When civil engineering projects utilize cast-in-place concrete structures, the concrete interface often requires a film covering. Covering with a film after pouring is a common method of concrete curing. This method requires immediate and complete coverage of the concrete. Frequent watering is unnecessary. The film preserves the initial volatile moisture of the concrete and provides a certain degree of insulation, creating a self-curing environment. Film covering effectively isolates moisture from the concrete surface from the atmosphere, reducing evaporation. It also allows the moisture to fully react with the cement in the concrete, reducing the internal stress generated by insufficient moisture during the hydration process, which can lead to early cracks in the concrete.

[0003] After the concrete is poured, it must be covered with film immediately. However, at this time, the concrete still has strong plasticity, which makes it extremely inconvenient for construction workers covered with film to walk, and there are also major safety hazards. Summary of the Invention

[0004] The utility model aims to solve the deficiencies of the prior art and provides an auxiliary tool for concrete flat surface covering.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] An auxiliary tool for concrete flat surface covering, comprising a plastic trough, a central shaft and a telescopic handle section. The plastic trough is door frame-shaped, the central shaft is detachably connected to the plastic trough by fixing bolts at both ends, the top of the plastic trough is connected to a fixing plate, two ear plates are fixed in parallel on the fixing plate, a rotating shaft is connected between the two ear plates by a rotating shaft fixing bolt, one end of the telescopic handle section is connected to the rotating shaft by the rotating shaft fixing bolt, and the other end of the telescopic handle section is sleeved with a rubber handle.

[0007] The plastic trough is composed of three stainless steel square tubes, and both ends of the main beam stainless steel square tube are welded to the side stainless steel square tubes by argon arc welding.

[0008] The telescopic handle section comprises a main telescopic handle and a secondary telescopic handle. The secondary telescopic handle is inserted into the main telescopic handle and is locked by a telescopic handle positioner.

[0009] The rotating shaft is a semi-cylinder that can rotate 180 degrees. A plug-in slot is provided on the plane of the semi-cylinder. The auxiliary telescopic handle is inserted into the plug-in slot and is fastened by the rotating shaft fixing bolts provided on both sides of the plug-in slot.

[0010] The telescopic handle locator is a locating pin, and corresponding pin holes are provided on the main telescopic handle and the auxiliary telescopic handle.

[0011] The telescopic handle positioner is a "Y"-shaped threaded bayonet. A nut is connected to the main telescopic handle. A thread is provided on the rod of the threaded bayonet and is connected to the nut.

[0012] The beneficial effects of the utility model are as follows: the utility model has a simple structure, is easy to assemble, and the device materials are easy to obtain. The relevant materials can be quickly found for assembly and put into use. Compared with the traditional artificial overall covering, the time for construction preparation and construction work is greatly reduced. The various parts of the structure in the device are all detachable bolts and telescopic rods, which are convenient for placement and turnover. The setting of the rotating axis can act on construction surfaces at different angles. It has a wide range of applications. The concrete covering film is closely contacted with the concrete surface through the weight of the device itself, reducing the contact between air and the concrete surface, so as to achieve a smooth and flat effect on the concrete surface.
