Description

Reinforced truss concrete superimposed sheet

Technical Field

The utility model relates to the technical field of concrete superimposed sheets, in particular to a reinforced truss concrete superimposed sheet.

Background

The laminated slab is used as an important construction of an assembled building, has been developed in stages, is an assembled integral floor slab formed by laminating precast slabs and cast-in-situ reinforced concrete layers, has good integrity, and is suitable for high-rise buildings and large-bay buildings with high overall rigidity requirements; the existing steel bar truss plates and the side connection with the cast-in-situ beam are required to be pre-buried with the anchor bars in advance at the earlier stage of manufacturing the steel bar truss plates, commonly called as 'Huzi ribs', but in the transportation and construction processes, the 'Huzi ribs' are easy to deform and bend downwards to be damaged due to the lack of support and protection, so that trouble is brought to site construction, and the construction difficulty is improved to a certain extent.

Further, the connecting piece is in T-shaped arrangement.

Further, a limit groove is formed in the lower portion of one end, far away from the laminated plate main body, of the connecting piece, and the cross section of the limit groove is semicircular.

Further, a pouring groove is formed in the top of the connecting piece, which is close to one end of the laminated plate main body.

Further, the height of the connecting piece is greater than one half of the height of the laminated plate body, and the height of the connecting piece is less than two thirds of the height of the laminated plate body.

Compared with the prior art, the utility model has the following beneficial effects:

this kind of steel bar truss concrete superimposed sheet, when prefabricated superimposed sheet main part, just place the connecting piece in the both sides of superimposed sheet main part, accomplish when the superimposed sheet main part is prefabricated, the connecting piece can inlay inside the superimposed sheet main part, when needs are in the same place two superimposed sheet main parts, only need insert respectively in the corresponding connecting piece of two superimposed sheet main parts with the both ends of connecting the reinforcing bar, then pour can, the concrete can directly flow into the spread groove, thereby link together two superimposed sheet main parts, above-mentioned structure makes the week side of superimposed sheet main part not reserve "huzi muscle" at needs, reduce the degree of difficulty of transportation and construction, reduce the construction degree of difficulty to a certain extent.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, a reinforced truss concrete laminated slab comprises a laminated slab main body 1, connecting steel bars 2 are connected between adjacent laminated slab main bodies 1, connecting pieces 3 are connected to two sides of the laminated slab main body 1, a connecting groove 4 is formed in one end, away from the laminated slab main body 1, of each connecting piece 3, and the connecting groove 4 is matched with the connecting steel bars 2.

According to the reinforced truss concrete laminated slab, the structure of the laminated slab main body 1 is similar to that of the reinforced concrete laminated slab disclosed in the patent with the application number of CN202221398595.7, so that the structure is not described in detail herein, when the laminated slab main body 1 is prefabricated, connecting pieces 3 are placed on two sides of the laminated slab main body 1, when the laminated slab main body 1 is prefabricated, the connecting pieces 3 are embedded in the laminated slab main body 1, when two laminated slab main bodies 1 are required to be connected together, only two ends of connecting reinforcements 2 are required to be respectively inserted into the connecting pieces 3 corresponding to the two laminated slab main bodies 1, and then pouring is carried out, concrete directly flows into the connecting grooves 4, so that the two laminated slab main bodies 1 are connected together, and the structure ensures that the periphery of the laminated slab main body 1 is not required to be reserved with 'hui tendons', so that the difficulty of transportation and construction is reduced to a certain extent.

As shown in fig. 4 and 5, the connector 3 is provided in a T-shape. The contact area of the connecting piece 3 arranged in the T shape and the laminated plate main body 1 is larger, and the connection is more stable.

As shown in fig. 1, 2, 4 and 5, a limiting groove 5 is formed in the lower portion of one end, far away from the laminated plate main body 1, of the connecting piece 3, and the cross section of the limiting groove 5 is semicircular. After the connecting steel bars 2 are placed in the connecting grooves 4 of the connecting pieces 3, the connecting steel bars 2 can directly sink into the limiting grooves 5, and then the connecting steel bars 2 are limited, so that the pre-fixing effect is achieved, the connecting steel bars 2 are prevented from moving, and the strength after pouring is influenced.

As shown in fig. 1 to 5, a pouring groove 6 is formed in the top of the connecting piece 3, which is close to one end of the laminated plate main body 1. Because connecting piece 3 is T type setting, so connecting bar 2 also can be U type setting for connecting bar 2 agrees with connecting piece 3 more, and when connecting piece 3 is T type setting, because connecting bar 2 is located the position of spread groove 4, therefore the concrete of pouring is likely blocked by connecting bar 2, leads to the unable inside entering connecting piece 3 of concrete, leads to the connection effect between two adjacent superimposed sheet main parts 1 to worsen.

As shown in fig. 1, 2 and 3, the height of the connector 3 is greater than one-half of the height of the laminated plate main body 1, and the height of the connector 3 is less than two-thirds of the height of the laminated plate main body 1. If the height of the connecting piece 3 is less than one half of the height of the laminated plate main body 1, the connecting effect is poor, and if the height of the connecting piece 3 is more than two thirds of the height of the laminated plate main body 1, the side edge of the laminated plate main body 1 is easily broken.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
