Embodiment 1

[0023] A kind of grid prefabricated composite board reference of this embodiment figure 1 , 2, including core board 1, core board 1 adopts EPS board with good heat insulation effect, and the bottom surface of core board 1 is connected with crisscross The steel wire is welded to form the steel wire mesh 2, and the steel wire mesh 2 and the core plate 1 are provided The oblique inserting ribs 3 are connected. The oblique inserting ribs 3 are evenly spaced and in different directions. One end is inserted into the core plate 1 obliquely and the end is 3-4cm, and the other end is welded with criss-crossed steel wires on the steel mesh 2; In between, the steel mesh 2 is covered by pouring to form a reinforced cement layer 4. The steel mesh 2 is longer than the core board 1, and the excess part extends out of the core board 1 to connect with other parts;

[0024] The sandwich floor slab adopting the above-mentioned grid prefabricated composite panel includes mutually spaced grid prefabr...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is:

[0033] The grid prefabricated composite panel sandwich floor slab is also laid between the grid prefabricated composite panel and the steel wire mesh 9 for fixing The steel mesh 6, the steel mesh 6 and the core plate 1 are provided with oblique inserts for connection, so that the core plate 1 and the upper steel mesh 6 are connected and fixed together, and then the upper part of the core plate 1 is poured to form a network frame Prefabricated composite panel sandwich composite floor.

[0034] The grid prefabricated composite board sandwich floor slab and its connection construction method of the above embodiments of the present invention adopts the grid prefabricated composite board composite with reinforced cement layer 4, which is cast-in-place at one time, has large bearing capacity, small dead weight, earthquake and fire resistance Good performance, reduce the amount of concrete and ceiling construction, simp...

Abstract

The invention relates to a net rack precast composite board sandwiched floor, which belongs to the novel building material structure technical field. The net rack precast composite board comprises a core plate 1 and is characterized in that: the bottom of the core plate 1 is connected with a steel wire gauze 2; an inclined dowel bar 3 is arranged between the steel wire gauze 2 and the core plate 1 for connection; and a reinforced cement layer 4 in which the steel wire gauze is coated through placement is formed between the steel wire gauze 2 and the core plate 1. The connecting construction method comprises the following steps: (1), precast slabs are mutually and alternately arranged; (2), connecting ribs 8 are connected between the precast slabs and fixed reinforcing steel bars are inserted into the connecting ribs 8; (3), steel wire gauzes 9 are laid on the precast slabs; (4), redundant parts of the steel wire gauzes 2 are connected with fixed reinforcing steel bars 5 and the steel wire gauzes 9 are connected with fixed reinforcing steel bars 7; and (5), a concrete cladding 10 is formed after placement of concrete. The invention adopts composition of the net rack precast composite board which is cast on site and formed at a time, thereby the amount of concrete and the construction amount of suspended ceilings are reduced; a moulding board is simplified; the overall rigidity and the sound insulation and heat preservation performances of the floor are improved; underfloor composite polyphenyl is favorable for laying pipelines. Moreover, the processing belongs to semi-precast, thereby the progress is quick; the cost is low; and the average amount of concrete is mostly saved.

Description

1. Technical Field [0001] The invention relates to a sandwich floor slab of a grid prefabricated composite board and a connection construction method thereof, and belongs to the technical field of new building materials structures. 2. Background technology [0002] The structure of the steel wire mesh polystyrene sandwich panel is scientific and reasonable, with good mechanical properties, and it is popular in many countries in Europe and the United States. Grid sandwich panel production equipment and technology were introduced to my country in the early 1980s, and it was a sensation in China. The country has compiled product standards for this, and application atlases have also been published in various regions, which have been widely used in construction projects. Good luck is not long. A large number of hand-made wire inserts flood the market, disrupting the normal order, lowering prices, barbarous construction, and general cracking of the surface plaster, which seriously aff...
