Description
Technical field
The invention belongs to technical field of building construction, and in particular to a kind of lintel prefabricated using U-shaped building block and its
Construction method.
Background technique
When opening up door-window opening on wall, and wall hole be greater than 300mm when, in order to support hole top masonry to be passed
The various loads come, and these loads are transmitted to the wall on the holes such as door and window both sides, crossbeam is often set on door-window opening, the cross
Beam is lintel.The construction method for making lintel, generally use be mounted on after concentration pre-casting lintel door-window opening it
On, or the secondary casting concrete after lintel corresponding position formwork and setting reinforcing bar.The former installs after generally requiring demoulding, after
Person is easy to influence masonry construction, and then influences construction speed and construction quality.
Summary of the invention
The object of the present invention is to provide a kind of lintel and its construction method prefabricated using U-shaped building block, the door and window mistakes
Beam is easy to make, and simple installation, building process does not need demoulding, does not interfere with masonry construction progress, conducive to shortening the construction period and mentioning
High construction quality.
To achieve the above object, the invention adopts the following technical scheme:
On the one hand, the present invention provides a kind of lintel prefabricated using U-shaped building block, which includes:
The opening up same column of muti-piece builds the U-shaped building block at groove body；
It is set up in the intracorporal at least one of slot and crosses beam steel；
And it is filled in the intracorporal concrete for wrapping beam steel of slot.
Wherein:
The groove body should have the length enough as lintel, and length will be adapted to the width in door and window hole.That is, the slot
The length of body should be greater than the door and window hole width of installation place, which is suitable for the case where door and window hole width is less than 1600mm.
The U-shaped building block is preferably dimensioned to be 190mm × 190mm × 190mm.
The gray seam thickness built between the U-shaped building block is 10 ± 2mm.
Quantity, specification and the layout for crossing beam steel, be according to the load of lintel, in conjunction with various countries, industry standard
It is calculated and is selected, this is ordinary skill in the art means, and detailed description is not added herein.
The concrete preferably uses C15 concrete, i.e. the strength grade concrete that is C15.
On the other hand, present invention offer also provides the construction method of the above-mentioned lintel prefabricated using U-shaped building block, this is applied
Work method the following steps are included:
1) before masonry is built, U-shaped building block is opening up, the groove body at lintel size is built, was installed in slot
Beam steel, there are cover to reinforcement, casting concrete, maintenance molding obtains prefabricated doors and windows lintel；
2) before masonry is built, floor structure face is levelling by absolute altitude, control line is released in wall, for controlling lintel
Absolute altitude；
3) when building wall to lintel absolute altitude, door and window hole both sides remains for overlapping in advance the position of U-shaped building block；
4) mortar is coated in above-mentioned reserved location, prefabricated doors and windows lintel is not necessarily to demoulding, is directly mounted to reserved location, hereafter
Continue to build using conventional method.
Wherein:
The concrete preferably uses C15 concrete, pours thickness no more than 40mm for every layer in concreting process.It smashes
The real duration is until making concrete surface laitance, bubble-free, not sinking.Casting process avoids collision reinforcing bar, U-shaped building block,
It was found that having deformation, displacement, should handle in time.Mode of the cast-in-place concrete in the U-shaped building block for having bound reinforcing bar can be used.
The U-shaped building block is completely grouted for side and is built, and must not have vertical straight joint, gray seam thickness 10 with delivery position by hole
±2mm。
The highly preferred of the control line is 1m.The width in the door and window hole should be less than 1600mm.The reserved location
Depth is not less than 240mm, is one of preferred with 240mm.
The beneficial effects of the present invention are:
Lintel of the invention is simple and reasonable, can be prefabricated by using U-shaped building block in a pre-installation, is building when prefabricated
What setting met design leader in block crosses beam steel after-pouring concrete, and lintel is mounted directly to door after prefabricated
At window opening, preparation is simple, and building block can directly be built on upper layer after completing by pouring, and next procedure is completed, without waiting for demoulding.
Compared with prior art, the invention has the following advantages that 1) casting concrete can directly start next procedure after completing, it is not necessarily to
Demoulding；2) secondary structure lintel can be served as in tall and big masonry, can continue next procedure without demoulding.
