Embodiment 1

[0042] The scheme of the present invention will be further described below in conjunction with specific examples, as figure 1 As shown, the bottom plate of the two-way laminated board is formed by the close-fitting connection of the first veneer 1 and the second veneer 1'. There is a post-casting groove 2 at every interval between the joints 5 of the two veneers. In the pouring groove 2, the connecting steel bar 3 is pre-embedded. Among the two connected veneers, the connecting steel bar 3 in the post-casting groove 2 of one of them is one (such as figure 2 As shown, a connecting steel bar 3 is pre-embedded in the back groove of the first veneer 1, and there are two connecting steel bars 3 in the corresponding rear pouring groove 2 of the other piece (such as image 3As shown, two connecting steel bars 3) are pre-embedded in the rear groove of the second veneer 1'. All connecting bar ends shall be pre-threaded. The connecting steel bars are connected by steel bar connectors...

Embodiment 2

[0054] Such as Figure 7 As shown, the bottom plate of the two-way laminated board in this embodiment is formed by three single boards closely connected by seams, and the rest of the technical parameters are the same as in Embodiment 1.

Abstract

The invention discloses a two-way composite slab bottom plate in dense seam splicing connection and a construction method thereof. The two-way composite slab bottom plate comprises two to three singleplates requiring dense seam splicing connection; a section of after pouring groove is formed in the splicing seam position of the single plate every a distance; connection steel bars are exposed fromthe after pouring grooves; screw thread processing is performed on the end parts of the connection steel bars; and the connection steel bars between the two connected single plates are connected through steel bars. The two-way composite slab bottom plate is made in a factory; after the two-way composite slab bottom plate is conveyed to the field and is hoisted, a steel bar connector is sleeved onto the steel bar positioned at one side of the seam; another bottom plate to be connected is hoisted, so that the grooves of the two bottom plates are aligned; the steel bar connector is sleeved ontothe connection steel bar at the other side; and the steel bar connection can be completed after the three connection steel bars are fastened by screw caps. After the steel bar connection, tension force can be exerted onto the steel bars through the screw caps; and the tension force can generate precompression force in concrete in the splicing seam positions, so that the use performance of a composite slab is improved.

Description

technical field [0001] The invention belongs to the technical field of design and construction of building industrialization, and in particular relates to a two-way laminated slab bottom plate connected by close-fitting joints and a construction method. Background technique [0002] The industrialization of construction is the current development trend of my country's construction industry, and it is an important step to realize the "four festivals and one environmental protection" green building. An important feature of building industrialization is that building components are prefabricated in factories as much as possible, making full use of the factory's industrial machinery and complete information management. The quality of components prefabricated in factories can often be guaranteed due to the standardization of construction and systematization of management. , can realize the error level of the construction industry from "centimeter level" to "millimeter level". ...
