Description

Connection structure and construction method of the prefabricated superimposed sheet of assembling type steel structure with girder steel
Technical field
The invention belongs to construction engineering technical field, the same steel of prefabricated superimposed sheet of specifically a kind of steel construction assembled-type house The connection method of beam.
Background technique
Assembling type steel structure building meets industry development, as national industry structural adjustment and building trade are to green energy conservation Facade lighting is advocated, and assembled architecture receives more and more attention, and the development of assembling type steel structure building being capable of power-assisted Steel goes production capacity, meets the policy goals of government.Typical Representative of the steel construction as green building, greatly reduces sand, stone, ash Dosage, in demolishing buildings, most of material can effectively reduce building waste with regeneration or degradation.
In assembled-type house, together by different combinations of materials, traditional method is to be laid with building in girder steel upper surface Board (profiled sheet) is linked together floor support plate with girder steel with penetrability peg in erecting bed, above floor support plate into Row concrete pours.Such method has also needed special messenger after being laid with floor support plate, makes peg above, virtually increases people Power, the investment of material resources, increase construction cost.
Summary of the invention
The present invention combines the existing structure of existing superimposed sheet and girder steel, to solve existing superimposed sheet with the connection construction of girder steel The disadvantages of steel doses is big, and investment manpower and material resources are larger is consumed, provides a kind of easy to operate, the girder steel that can reduce construction cost is same The connection structure and connection construction method of superimposed sheet.
Specifically, the scheme that the present invention uses is as follows:
With the connection structure of girder steel, it includes taking on girder steel girder steel top flange plate for a kind of prefabricated superimposed sheet of assembling type steel structure Superimposed sheet is connect, the superimposed sheet four corners are equipped with built-in fitting, which is made of two dowels and a plain plate, dowel It is poured when superimposed sheet is prefabricated in plate, plain plate is on superimposed sheet and girder steel overlap joint side end face;Girder steel top flange plate both ends Top is equipped with angle steel corresponding with built-in fitting position, and angle steel plane is bonded and welded with plain plate;It is set between the superimposed sheet of two sides There is reinforcing bar and has poured concrete.
A kind of prefabricated superimposed sheet of assembling type steel structure follows these steps to carry out with the connection construction method of girder steel:
(1) built-in fitting is added in superimposed sheet production process in advance at four angles, built-in fitting includes two dowels and one A plain plate, plain plate are embedded on the end face of superimposed sheet and girder steel connecting side;
(2) a pair of of angle steel is respectively welded on the both ends of girder steel top flange, angle steel is corresponding with the built-in fitting position of superimposed sheet;
(3) in the evenly spaced weld stud in girder steel top flange;
(4) superimposed sheet is ridden upon on girder steel, adjustment finishes angle steel is welded with built-in fitting;
(5) superimposed sheet installation is completed in Civil Specialities assembling reinforcement, casting concrete.
The angle steel specification is L100*63*8.
Built-in fitting is located at four diagonally opposing corners of superimposed sheet.
Connection method provided by the invention compared with prior art, eliminates the use of floor support plate (profiled sheet), can save About a large amount of steel avoid the work of erecting bed welding penetrability peg, and work is shifted to an earlier date factory and is completed, that is, accelerates work Phase also complies with national requirements for environmental protection.

Specific embodiment
Technical solution of the present invention is described in detail in 1-6 with reference to the accompanying drawing:
The present invention is superimposed sheet and the girder steel overlap joint work simplified in existing construction, proposes new connection structure and its applies Work method is not related to floor support plate application in new departure, and the work for penetrating peg does not carry out at the construction field (site), i.e. saving material, again Can obviously it accelerate the duration.
The prefabricated superimposed sheet of steel construction assembled-type house that the present invention designs is with the connection structure of girder steel: 4 four jiaos of superimposed sheet Place is equipped with built-in fitting 5, which is made of two dowels and a plain plate, dowel poured when superimposed sheet 4 is prefabricated in In plate, plain plate is on superimposed sheet and girder steel overlap joint side end face;It is equipped with and built-in fitting position at the top of 1 top flange plate both ends of girder steel Corresponding angle steel 3,3 plane of angle steel are bonded and welded with plain plate;It is equipped with reinforcing bar 6 between the superimposed sheet of girder steel two sides and pours There is concrete.
The present invention also provides the prefabricated superimposed sheets of assembling type steel structure with the connection construction method of girder steel:
(1) add built-in fitting 5 in 4 production process of superimposed sheet in advance at four angles, built-in fitting 5 include two dowels and One plain plate, plain plate are embedded on the end face of superimposed sheet and girder steel connecting side;
(2) a pair of of angle steel 3 is respectively welded on 1 top flange both ends of girder steel, angle steel 3 is opposite with 5 position of built-in fitting of superimposed sheet It answers;
(3) in the evenly spaced weld stud 2 in 1 top flange of girder steel;
(4) superimposed sheet 4 is ridden upon on girder steel 1, adjustment finishes angle steel 3 and built-in fitting 5 is welded;
(5) superimposed sheet installation is completed in Civil Specialities assembling reinforcement 6, casting concrete.
This programme is illustrated below by a construction embodiment:
(1) M16 peg 2 is welded in 1 top flange interval 200mm of girder steel.Peg 2 used herein can be with overlapping plate thickness not Peg that is same and selecting different size.When scene overlaps plate thickness 120mm, using M16*100;And when overlapping plate thickness 140mm, it fits With using M16*120.
(2) be prepared in advance built-in fitting, and built-in fitting is by two reinforcing bars and one block of plain plate is affixed forms.
(3) when factory makes superimposed sheet 4, four built-in fittings 5 is separately positioned on four diagonal angles of superimposed sheet, allow flat steel Plate after installing in next step in place, is welded and fixed in overlapping plate end face with girder steel 1.The position of built-in fitting is equipped with overlapping At the diagonally opposing corner of plate.
(4) angle steel 3 is welded on 1 top flange of girder steel, angle iron position is corresponding with built-in fitting, and each position of angle steel 3 is a pair, Angle steel plane is outside, welded with the built-in fitting on the superimposed sheet of two sides respectively, and the size of angle steel is L100*63*8.
(5) superimposed sheet 4 is installed in place, if any inclination, is adjusted with crowbar, after adjustment, welds angle steel 3 and built-in fitting 5, Superimposed sheet 4 is connected and fixed with girder steel 1.
(6) conventional method assembling reinforcement 6, casting concrete are used, superimposed sheet is connected as one with girder steel.
The above is only preferred embodiments of the present invention, not does any restrictions in structure to the present invention, it is all according to According to the simple modification that essence of the invention makes above example, within the scope of category technical solution of the present invention.
