Description

A multifunctional device for floor construction using steel decks

technical field

The utility model relates to a floor construction device, in particular to a multifunctional device for floor construction using a steel bearing plate.

Background technique

In existing buildings with hollow floors, solid spherical polyamides are embedded between the reinforcement layers to achieve floor weight reduction, heat insulation, and sound insulation, instead of traditional concrete floors. However, when the solid spherical polycarbonate is buried, since the polycarbonate is a light-weight material, the reinforcement layer carrying the polycarbonate is very easy to float from the lower formwork together with the polycarbonate due to the weight reduction during grouting. Like this, will seriously hinder the carrying out of whole construction process.

Therefore, in order to avoid the situation in the prior art that the overall reinforcement layer and the polyamide float together from the lower formwork due to overall weight reduction, anchor bolts are usually used to fix the overall reinforcement layer on the formwork layer. Structurally, the anchor bolt has a latch and a hook. In practice, the builder must first drill a hole in the formwork layer, then penetrate the anchor bolt part into the hole, and use the hook to hook the steel bar of the upper reinforcement layer, so as to secure the whole The reinforcement layer is fixed on the formwork layer.

In recent years, the use of steel bearing plates to replace the original formwork layer has been increasing year by year, and it is mainly used in buildings with steel frame structures. The steel deck can not only act as the reinforcement of the floor to increase the structural strength, but also does not need to use temporary support like the existing formwork layer. Generally speaking, steel bearing plates can be divided into three types: open type, necked type and closed type. When the steel deck is used to replace the formwork layer, the floating problem of the overall reinforcement layer still exists due to the weight reduction of the overall floor slab. However, if the existing anchor bolts are used to fix the reinforcement layer, holes must be drilled in the steel deck, which will destroy the structure of the steel deck.

In addition, when constructing general concrete slabs using steel decks, there will be the following problems:

First of all, in the prior art, in order to avoid direct pressing of the overall reinforcement layer (including the upper reinforcement layer and the lower reinforcement layer) on the formwork layer, pads such as stones or concrete blocks are often used to place them Between the lower reinforcement layer and the template layer to separate the reinforcement layer and the template layer. In floor construction where steel decks are used instead of formwork decks, the reinforcement deck must also be raised to isolate it from the deck. However, since the spacers used are usually difficult to manufacture according to fixed specifications, that is, the heights of the spacers may be different from each other, which will cause troubles in use. In addition, even if the pads used are all of the same specification, since the pads are not fixed under the lower reinforcement layer or on the steel bearing plate, they will easily slide away from their original placement, which may cause the entire reinforcement layer to tilt.

Secondly, in order to support the structure of the overall steel bar layer (including the upper steel bar layer and the lower steel bar layer), the prior art is to use a Z-shaped support frame or a support chair folded from steel bars as a support between the upper steel bar layer and the lower steel bar layer. . Taking the Z-shaped support frame as an example, it includes an upper horizontal part, a lower horizontal part and a nearly vertical support part, wherein the upper horizontal part and the lower horizontal part are bound to the upper reinforcement layer and the lower reinforcement layer respectively. Since the distance between the upper steel bar layer and the lower steel bar layer is about a fixed value, if the height of the support part of the Z-shaped support frame is close to the vertical when it is not uniformly specified during manufacture and there is an excessive gap, it will cause problems in use. difficulty. Moreover, no matter whether the Z-shaped support frame or the support chair is used, the overall construction cost will increase.

Its three, when grouting, because reinforcing bar layer and steel bearing plate are not necessarily horizontal, when only concrete is filled with reinforcing bar layer, its floor slab ground may not be level, but has an inclination angle. Therefore, in floor construction, in order to ensure the levelness of the floor, the level gauge is usually used as an indicator of the height that the concrete should be added. The existing level gauge includes a base, an adjustable part and an indicating part, wherein the base is fixed on the formwork layer with nails, the indicating part is connected with the spring provided in the adjustable part, and by adjusting the spring And the indicating part is moved up or down. However, in the case of using a steel deck to replace the formwork layer, if nails are used to fix the leveler to the steel deck, the structure of the steel deck will also be damaged. In addition, the adjustable height range of the altimeter is also limited, and because of its complex structure, more manpower and time must be spent on adjusting it, which leads to an increase in the overall construction cost.

In view of this, in order to improve the above shortcomings, there is a need for a device that can simultaneously fix and support the reinforcement layer, isolate the reinforcement layer and the steel reinforcement layer, and mark the pouring height of the concrete without destroying the steel deck structure. .
