Abstract
The utility model provides an add structural slab quick connect structure behind instrument formula, including prefabricated light floor, prefabricated light floor's both ends are reserved there is the reinforcing bar, and the back adds the structural slab and treats the old structural slab at mounted position both ends and the reservation reinforcing bar welded fastening at prefabricated light floor both ends, and cast in situ concrete has been pour with the junction of prefabricated light floor to old structural slab, and pours the department and pass through instrument formula aluminium template die sinking. The problems that the construction period is long, the construction difficulty is high, the turnover cannot be achieved and the like in the traditional mode of adding the structural slab afterwards are solved. Belongs to the technical field of building structure engineering.
Description
Technical Field
The utility model relates to an add structural slab quick connect structure behind instrument formula belongs to building structure engineering technical field.
Background
In the rapid development process of buildings in China, a rear plate adding ratio is added in some transformation projects. The traditional mode of adding the structural slab after construction has long construction period, great construction difficulty and no turnover, needs a large construction site and a lot of manpower, and adds the load of the old slab, thereby having certain influence on the stress of the old structural slab and the beam.
Disclosure of Invention
The utility model aims to provide a: the utility model provides a add structural slab quick connect structure behind instrument formula to add structural slab mode construction cycle length, the construction degree of difficulty is big, can not have enough to meet the need the scheduling problem after solving the tradition.
In order to solve the problems, the tool type rear-added structural slab quick connection structure is proposed to be adopted and comprises a prefabricated light floor slab, reinforcing steel bars are reserved at two ends of the prefabricated light floor slab, old structural slabs at two ends of a position, where the rear-added structural slab is to be installed, are welded and fixed with the reserved reinforcing steel bars at two ends of the prefabricated light floor slab, cast-in-place concrete is poured at the joint of the old structural slabs and the prefabricated light floor slab, and the pouring position is subjected to mold assembly through a tool type aluminum template.
Among the aforementioned quick coupling mechanism, the old structural slab department that adds the structural slab after and treat the mounted position both ends is dug and is exposed old structural slab reinforcing bar, old structural slab carries out the single face welding through the reinforcing bar that old structural slab reinforcing bar and prefabricated light floor both ends were reserved.
The specific method comprises the following steps:
firstly, prefabricating a light floor slab in a processing plant, reserving reinforcing steel bars meeting the welding requirement on length at two sides of the prefabricated light floor slab, hoisting the prefabricated light floor slab to a specified position by using a hoisting mode, chiseling old structural slabs at two ends of a position where a post-added structural slab is to be installed by using a percussion drill before the process, wherein the length of the exposed reinforcing steel bars meets the welding requirement; and then, performing single-side welding on the steel bars at the joint of the prefabricated light floor slab and the old structural slab, then using a turnover quick-release tool type aluminum template to mold the joint area, and pouring high-grade 8% micro-expansion concrete after the mold is molded.
Compared with the prior art, the utility model discloses can carry out quick butt joint with old structural slab to modes such as prefabricated light floor with hoist and mount in the work progress, the instrument formula aluminium template that adds can effectively improve the roughness requirement of floor, reduces wrong platform, improves construction quality, and the construction is quick, and the cycle is short, and the construction degree of difficulty is little, and instrument formula aluminium template can be dismantled the turnover fast and use, can solve fabulous the problem that prior art exists.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below.
Example (b):
referring to the attached drawing 1, this embodiment provides a tool type rear-mounted structural slab quick connection structure, including prefabricated light floor 2, the reinforcing bar is reserved at the both ends of prefabricated light floor 2, and the rear-mounted structural slab waits that old structural slab 3 at mounted position both ends and the reserved reinforcing bar welded fastening at prefabricated light floor 2 both ends, and cast-in-place concrete 4 has been pour with the junction of prefabricated light floor 2 to old structural slab 3, and the department of pouring is through 1 dress moulds of tool type aluminum mould board.
The specific method comprises the following steps:
firstly, prefabricating a light floor slab 2 in a processing plant, reserving reinforcing steel bars meeting the welding requirement on length at two sides of the prefabricated light floor slab 2, hoisting the prefabricated light floor slab 2 to a specified position by using a hoisting mode, chiseling old structural slabs 3 at two ends of a position where a post-added structural slab is to be installed by using a percussion drill before the process, wherein the length of the exposed reinforcing steel bars meets the welding requirement; and then, carrying out 8d (d is the diameter of the steel bar) single-side welding on the steel bar at the joint of the prefabricated light floor slab 2 and the old structural slab 3, then using the turnover quick-release tool type aluminum template 1 to mould the joint area, and pouring high-grade 8% micro-expansion concrete after the mould filling is finished.
The above embodiments are only used for illustrating but not limiting the technical solutions of the present invention, and although the present invention is described in detail with reference to the above embodiments, those skilled in the art should understand that: the present invention may be modified or substituted with equivalents without departing from the spirit and scope of the invention, which should be construed as being limited only by the claims.
