Description
Technical field
The invention belongs to technical field of buildings, are related to assembled composite wall structure wall connecting, in particular to one kind is based on
The assembled composite wall structure of mild steel plate welded connecting key.
Background technique
Currently, the building industry in China still uses traditional handicraft in large quantities, traditional handicraft exists: the waste of raw material scene
Greatly, long construction period, building energy consumption are big, build the garbage environment pollution generated, influence of noise resident living, dust pollution air
The disadvantages of.In view of the above problems, development is applicable in, economy, green building, horizontal Building technology, safety standard and engineering matter are improved
Amount, wideling popularize assembled architecture is a trend.Assembled architecture has design standard, component production industrialization, construction
The features such as mechanization, can greatly reduce situ wet operation and the use of labour by prefabricated construction, be that China will be built in future
The main direction of development built.
The key of prefabricated concrete structure success or failure be between prefabricated components and prefabricated components with it is cast-in-place and after pour it is mixed
Contour connection technology between solidifying soil, the tectonic sieving of selection and connecting node including jointing.Prefabricated panel
Interconnection technique can be divided into wet type connection by construction method and connect with dry type.Wet type connection is passed through between two prefabricated components
Grouting material is perfused to be attached in casting concrete；Wet type connection is commonly used and is easily connected in prefabricated components connection type
Mode, has that construction is more convenient, quality of connection is good, integrality performance of the structure is closer to cast-in-place concrete structure.Dry type connection
It is then to be attached by being implanted into reinforced bar sleeve or built-in fitting in prefabricated components by sleeve grouting, bolt or welding etc.
Mode；Dry type connection is higher with precision, shorten construction period, easily reparation is damaged after node shake, convenient for remote districts installation etc.
Advantage is the development trend of the following assembled interconnection technique.Dry type is connected and is mutually tied with energy-dissipating and shock-absorbing principle by seminar's novelty
Conjunction forms novel energy-consumption connection, and applies it in assembled composite wall structure, and structure is not only enable to have good carrying
Power also makes it show preferable energy dissipation capacity, it is proposed that for the interconnection technique that assembled combined wall vertically stitches, the technology
It is lower to design reasonable, easy for construction and input cost, and switching performance is also relatively good, realizes industrialized production, mechanization
Construction, economizes on resources, is environmentally protective, meeting current housing industrialization developing direction.

The present invention also provides the construction method of the assembled composite wall structure that key is welded to connect based on mild steel plate, steps
It is rapid as follows:
Step 1: the production of prefabricated combined wall board 3
Dedicated steel form is assembled first, is well placed pre-embedded steel slab 2, and bottom casting concrete puts ecological bulk immediately, will
Cross rib, the reinforcing bar with longitudinal ribs processed is put into template, it is to be confirmed it is errorless after, then casting concrete then catches up with flat, plastering, prefabricated
Standard curing is carried out after the completion, and when intensity reaches requirement, form removal forms prefabricated combined wall board 3；
Step 2: the vertical seam connection of wall
It is connected up to requirement to two pieces of prefabricated 3 horizontal joints of combined wall board, energy consumption junction steel plate 5 and two Pin of level is prefabricated multiple
The pre-embedded steel slab 2 for closing wallboard 3 is welded, and is had the prefabricated combined wall board 3 of two Pin and is reliably connected；
Step 3: vertical piece processing
HDPE plate is filled in prefabricated combined wall board 3 vertically seam, then fine gap is sealed using sealant and is filled out
Plug, it is finally levelling to vertically stitching using mortar.
Compared with prior art, the beneficial effects of the present invention are:
1. the connection type is dry type connection, there is higher precision, shortening construction period, node shake compared with traditional wet connection
It is damaged afterwards and easily repairs, is convenient for the advantages that remote districts installation.
2. dry type connection uses low yield point steel plate, plastic deformation ability is preferable, and ribs is arranged in surrounding, can both increase
Strong Wasted-energy steel plate stress-bearing capability, and active force can be made to be evenly distributed in Wasted-energy steel plate, and built-in fitting washability is good, is easy to make.
3. the geological process that can preferably dissipate inputs to the energy of structure using the structure of Wasted-energy steel plate connection, connection is same
When have both energy dissipation capacity.
4. piece processing mode is easy to operate, density is good.
