Embodiment 1

[0036] Such as Figure 1-Figure 7 Shown:

[0037] The invention provides a novel two-way stressed laminated slab and its construction method to achieve the purpose of improving shear resistance.

[0038] In order to solve the problem of poor shear resistance of existing laminated slabs, we invented and designed a laminated slab, including reinforced concrete poured laminated slabs, the front of the laminated slab is provided with a groove, and the groove is along the edge of the laminated slab Open to the interior of the laminated plate bottom plate. The present invention arranges grooves on the edge of the laminated slab bottom, so that the cast-in-place concrete can be directly grouted into the groove during later construction, so that the cast-in-place concrete and the laminated slab bottom are completely combined together, and the purpose of improving the shear resistance is achieved . Preferably, the bottom of the laminated slab is equipped with steel bars, the ends of...

Embodiment 2

[0050] Such as Figure 1-Figure 7 Shown:

[0051] Due to the thinner base plate of the laminated plate and the groove design around the base plate of the laminated plate, the surrounding structure of the base plate of the laminated plate and its own structure will be easily damaged during transportation. Therefore, we have designed a set of transshipment specially for the base plate of the laminated plate Structure, a kind of operation structure of the laminated plate bottom plate, including the laminated plate bottom plate 1 and the suspension ring 43 embedded from the front of the laminated plate bottom plate 1, and also includes the latch 42 penetrating through the inner ring area of ​​the suspension ring 43, and also includes two pins respectively located on the two sides of the suspension ring 43. The channel steel on the side and the bolt 42 are inserted into the groove bottoms of 2 channel steels, and the 2 channel steels and the bolt 42 constitute the spreader 4; Groo...

Embodiment 3

[0055] Such as Figure 1-Figure 7 Shown:

[0056] A construction method based on a novel two-way stressed laminated slab includes the following steps:

[0057] S1: hoist the laminated plate base 1 to a predetermined plane, so that two adjacent laminated plate bases 1 are arranged side by side,

[0058] S2: Set the annular steel bar 8 in the groove, so that the steel bar 2 is inserted into the inner ring area of ​​the annular steel bar 8, and use the bar binding technology to tie the annular steel bar 8 and the steel bar 2 together to form a reinforcement cage.

[0059] S3: Fill concrete in the groove and on the front of the laminated slab bottom plate 1, form a concrete pouring body 6 in the groove, and form a cast-in-place layer 7 on the front of the laminated slab bottom 1.

[0060] The specific steps of S1 are: pre-embed the lifting ring 43 from the front of the laminated slab bottom plate 1 inward, use 2 channel steels and bolts 42 to form the lifting device 4, the bolt ...

Abstract

The invention discloses a novel bidirectional bearing laminated slab comprising at least two adjacent laminated slab base plates (1) arranged in parallel; the laminated slab base plate (1) is formed by pouring reinforced concrete; the front side of each laminated slab base plate (1) is provided with grooves (3); the groove is arranged along the edge of the laminated slab base plate (1) and extends to the inner side of the laminated slab base plate (1); steel bars (2) are arranged in the laminated slab base plate (1); the end portion of the steel bar (2) bends and inserts the groove (3), and the position of the steel bar end portion in the vertical direction is lower than or equal to the front side of the laminated slab base plate (1); a ring bar (8) is arranged in the groove; the end portion of the steel bar (2) inserts the inner ring of the ring bar (8); the concrete can be poured into the grouting grooves so as to form the concrete pouring body (6).

Description

technical field [0001] The invention relates to the field of building technology, in particular to a novel two-way stressed laminated slab and a construction method thereof. Background technique [0002] In the existing construction technology, the laminated floor is a better structural form combining prefabricated and cast-in-place concrete. Combined with the upper cast-in-place concrete layer to become a whole, work together. The prestressed main reinforcement of the thin slab is the main reinforcement of the laminated floor, and the upper concrete cast-in-place layer is only equipped with negative moment reinforcement and structural reinforcement. That is to say, the bottom slab of the existing cast-in-place layer has a concrete slab with steel bars arranged inside. The laminated slab bottom slab of this structure has a simple structure and is easy to process and form, but its shear resistance is poor. Contents of the invention [0003] The invention provides a novel ...
