Abstract
The present invention provides after a kind of tool-type plus structural slab fast joint structure and method, including precast light floor, the both ends of precast light floor are reserved with reinforcing bar, afterwards plus the old structure plate at structural slab position both ends to be installed and the reserved steel bar at precast light floor both ends are welded and fixed, the junction of old structure plate and precast light floor has poured cast-in-place concrete, and the place of pouring is die-filling by tool-type aluminum alloy pattern plate.By solve tradition after plus structural slab in a manner of long construction period, difficulty of construction is big, can not have enough to meet the need the problems such as.Belong to structural engineering technical field.
Description
Technical field
The present invention relates to structural slab fast joint structure and method is added after a kind of tool-type, belong to structural engineering technology
Field.
Background technique
In fast development process, increase back strengthening plate in some improvement projects can be found everywhere China's building.After tradition plus tie
Structure plate mode long construction period, difficulty of construction is big, can not have enough to meet the need, and needs very big construction site and many manpowers, and aggravate
The weight bearing of old plate has certain influence to old structure plate, beam stress.
Summary of the invention
It is an object of the invention to: it provides after a kind of tool-type plus structural slab fast joint structure and method, to solve to pass
After system plus structural slab mode long construction period, difficulty of construction is big, the problems such as can not having enough to meet the need.
To solve the above problems, adding structural slab fast joint structure after such a tool-type of proposed adoption, including prefabricated light
The both ends of matter floor, precast light floor are reserved with reinforcing bar, rear plus structural slab position both ends to be installed old structure plates with it is prefabricated
The reserved steel bar at light floor both ends is welded and fixed, and the junction of old structure plate and precast light floor has poured cast-in-place coagulation
Soil, and the place of pouring is die-filling by tool-type aluminum alloy pattern plate.
In aforementioned quick-connect machanism, exposing is chiselled at rear plus structural slab position both ends to be installed old structure plates and is had been friends in the past knot
Structure slab muscle, the old structure plate carry out single welding by the reinforcing bar that old structure slab muscle and precast light floor both ends are reserved
It connects.
The specific method is as follows for it:
First in processing factory's precast light floor, the reinforcing bar for meeting welding requirements length is reserved on precast light floor both sides,
Precast light floor is hung to designated position using lifting mode, this crosses Cheng Qian and needs to wait pacifying to rear plus structural slab using impact drill
The old structure plate at holding position both ends is chiselled, and the reinforcing bar length of exposing meets welding requirements；Then by precast light floor with
Reinforcing bar at old structure plate docking carries out single-sided welding, and subsequently use can have enough to meet the need Quick Release tool-type aluminum alloy pattern plate and carry out to docking area
It is die-filling, die-filling high 8% slightly expanded concrete of a grade of completion after-pouring.
Compared with prior art, the present invention can in the construction process prefabricated light floor lift etc. modes with
Old structure plate carries out rapid abutting joint, and the tool-type aluminum alloy pattern plate added can effectively improve the flatness requirement of floor, reduces faulting of slab ends,
Construction quality is improved, and is constructed quickly, the period is short, and difficulty of construction is small, and tool-type aluminum alloy pattern plate quick release is used in turn, can
It admirably solves the problems, such as described of the existing technology.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention will be made below further detailed
Explanation.
Embodiment:
Referring to attached drawing 1, the present embodiment provides add structural slab fast joint structure, including precast light building after a kind of tool-type
The both ends of plate 2, precast light floor 2 are reserved with reinforcing bar, rear plus structural slab position both ends to be installed old structure plates 3 and prefabricated light
The reserved steel bar at 2 both ends of matter floor is welded and fixed, and the junction of old structure plate 3 and precast light floor 2 has poured cast-in-place coagulation
Soil 4, and the place of pouring is die-filling by tool-type aluminum alloy pattern plate 1.
The specific method is as follows for it:
First in processing factory's precast light floor 2, the reserved steel for meeting welding requirements length in 2 both sides of precast light floor
Muscle is hung precast light floor 2 to designated position using lifting mode, this crosses Cheng Qian and needs using impact drill to rear plus structural slab
The old structure plate 3 at position both ends to be installed is chiselled, and the reinforcing bar length of exposing meets welding requirements；Then by precast light building
Plate 2 carries out 8d (d is bar diameter) single-sided welding with the reinforcing bar at 3 place of docking of old structure plate, and subsequently use can have enough to meet the need Quick Release work
Tool formula aluminum alloy pattern plate 1 carries out die-filling, die-filling high 8% slightly expanded concrete of a grade of completion after-pouring to docking area.
The above embodiments are only used to illustrate and not limit the technical solutions of the present invention, although referring to above-described embodiment to this hair
It is bright to be described in detail, it will be apparent to an ordinarily skilled person in the art that: still the present invention can be modified or be waited
With replacement, without departing from the spirit or scope of the invention, or any substitutions, should all cover in power of the invention
In sharp claimed range.
