Method for connecting prefabricated floor and prefabricated vertical component

A technology of vertical components and connection methods, which is applied to floors, building components, building structures, etc., can solve the problems of inability to achieve integral prefabrication of walls and floors, low prefabrication assembly rate, and multiple on-site wet operations, so as to improve prefabrication The assembly rate, the mechanical performance of the floor are excellent, and the effect of reducing the length of the shelving

Problems solved by technology

Although this method reduces the floor formwork, there are still more on-site wet operations, and the prefabrication rate is still low
The second form is: the prefabricated slab is placed on the wall, and the steel bars at the joints of the post-cast concrete are reliably connected. This method has more connections and cannot realize the overall prefabrication of the wall and the floor.

Embodiment Construction

[0015] See figure 1 , a method for connecting a prefabricated floor slab and a prefabricated vertical member, the feature of the present invention is that the steps are:

[0016] 1) The connection between the prefabricated floor slab and the prefabricated vertical member of the concrete cast-in-place slab; wherein, the concrete cast-in-place slab is set at the junction of the prefabricated floor slab and the prefabricated vertical member, and the connecting end surface of the prefabricated floor slab is provided with a rough surface or a toothed surface; The upper and lower steel bars on the prefabricated floor form a closed loop and extend into the post-casting belt, and the prefabricated vertical member protrudes from a corner of the circular steel bar. The two kinds of steel bars form a new closed loop (the position of the closed loop is on the prefabricated vertical component), and the closed loop is inserted longitudinal reinforcement;

[0017] 2) The concrete cast-in-pl...

Abstract

A method for connecting a prefabricated floor and a prefabricated vertical component is characterized in the steps that (1) the prefabricated floor of a concrete cast-in-place plate strip is connected with the prefabricated vertical component, wherein the concrete cast-in-place plate strip is disposed at the joint between the prefabricated floor and the prefabricated vertical component, and a rough face or a teeth-shaped face is disposed on a connecting end face of the prefabricated floor, and upper and lower reinforcing steel bars of the prefabricated floor form a closed circle and are stretched into a rear casting strip, the prefabricated vertical component is stretched from one corner of an annular reinforcing steel bar, the two kinds of reinforcing steel bars form a new closed circle, and longitudinal reinforcing steel bars are inserted into the closed circle; and (2) the concrete cast-in-place plate strip is poured by fine aggregate concrete. The method for connecting the prefabricated floor and the prefabricated vertical component provided by the invention is beneficial in that the method can reduce a lot of floor wet construction and can realize overall prefabrication of a wall body and the floor. The method for connecting the prefabricated floor and the prefabricated vertical component provided by the invention increases an assembly rate of a building, reduces a floor thickness, avoids cracks at a floor support and can also satisfy overall performance of the floor.

Description

Background technique [0001] At present, the way of building houses in my country is mainly based on wet work, which has waste of materials, difficulties in winter construction, a lot of ground ash and other construction waste, dust on construction sites affects urban air quality, and it is difficult to effectively guarantee building quality. Decoration may damage the original There are structural and other issues, so the form of prefabricated concrete structures is gradually advancing. [0002] At present, there are basically two types of connection forms between prefabricated concrete structure floors and vertical members in China. The first form is: use prefabricated laminated slabs, and then pour a layer of concrete after the entire layer. Although this method reduces the floor formwork, there are still more on-site wet operations, and the prefabrication rate is still low. The second form is: the prefabricated slab is placed on the wall, and the steel bars at the joints of...
