Abstract
The invention relates to a construction process for a building member, in particular to a construction process for a precast beam slab joint. The construction process comprises the following steps of: 1) arranging a groove-shaped precast beam shell at a planned position, mounting a precast floor slab bottom die on an outer notch supporting boss of the precast beam shell, and then supporting and fixing the precast beam shell and the precast floor slab bottom die respectively; 2) inserting a reserved reinforcing steel bar of the precast floor slab bottom die into a notch of the precast beam shell, and then arranging a main bar of a beam in the precast beam shell; 3) paving and fixing floor upper-layer supporting seat reinforcing steel bars above the precast floor slab bottom die; and 4) placing concrete on the precast beam shell and the precast floor bottom die. By adoption of the construction process for the precast beam slab joint of the technical scheme, the construction speed is high, the standardization level is high, and a template is not needed to be dismounted.
Description
Technical field
The present invention relates to a kind of construction technology of building member, be specifically related to a kind of construction technology of precast beam joint.
Background technology
Along with the development of urbanization process, the high buildings and large mansions construction is quick, and in order to satisfy the quake-resistant safety requirement, existing high-rise building adopts the integrated poured building frame of steel concrete more, and then on building frame, builds divider wall.The building frame structure generally comprises load bearing wall, post, beam and floor, and its central sill and floor adopt steel concrete to accomplish to the moulding of template one-time-concreting more.
The job practices of tradition cast-in-place beam and floor needs the scene to roll reinforcing bar, measurement and mounting template and fix, and this construction technology exists some following problems: 1, because the rolling at the construction field (site) reinforcing bar of workman's needs takies a large amount of engineering times; 2, because the workman measures installation and fixed form after need installing reinforcing bar more at the construction field (site), the installation accuracy of template varies with each individual, and standardization level is low; 3, behind the beam and sheet metal forming of cast-in-situ concrete, also need stripping, the speed of application that this not only causes a large amount of template wastes easily but also has a strong impact on beam slab.
Summary of the invention
It is fast that the technical problem that the present invention will solve provides a kind of speed of application, and standardization level is high and need not the construction technology of the precast beam joint of stripping.
In order to solve the problems of the technologies described above, the present invention provides a kind of construction technology of precast beam joint, includes following steps:
1) flute profile precast beam shell is arranged to planned position, the precast floor slab bed die is installed on the exterior notch support rim of precast beam shell, distinguish support fixation precast beam shell and precast floor slab bed die then;
2) reserved steel bar with the precast floor slab bed die is inserted in the notch of precast beam shell, in the precast beam shell, settles the main muscle of beam then;
3) above the precast floor slab bed die, lay and fixing floor upper strata bearing reinforcing bar;
4) fluid concrete on precast beam shell and precast floor slab bed die.
Wherein, flute profile precast beam shell is a mill work, and material can be concrete or other materials, and its inside is provided with stirrup, in order to substitute traditional beam forms; The precast floor slab bed die also is a mill work, is provided with gauze wire cloth in it, in order to substitute traditional floor support shuttering; Upper strata bearing reinforcing bar is a prefabrication, and cooperates with precast floor slab bed die size.
Precast beam shell after the cast and precast floor slab bed die do not need to remove as the part of beam slab joint.
As preferred version, in order to alleviate the weight of beam slab, the concrete described in the step 4) is a light weight aggregate concrete.
Adopt the construction technology of the precast beam joint of technical scheme of the present invention to have following advantage: 1; The stirrup of beam is to be arranged in the beam shell in advance; The main muscle of beam only need directly be placed in the bottom and the top of precast beam shell; The upper strata bearing reinforcing bar of precast floor slab bed die also is that factory is pre-processed, and therefore than traditional construction technology, it has practiced thrift the time of on-the-spot wiretie greatly; 2, because precast beam shell and precast floor slab bed die are prefabrication, its standardization level is high, and the ingredient as beam slab need not to remove after the cast, so speed of application is fast.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:
Fig. 1 is the precast beam joint design sketch map of the construction technology of precast beam joint of the present invention;
Fig. 2 is the enlarged diagram of I part among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of construction technology of precast beam joint includes following steps:
1) flute profile precast beam shell 1 is arranged to planning such as column cap position; Precast floor slab bed die 2 is installed on the exterior notch support rim 3 of precast beam shell 1, then through scaffolding steel pipe or other fastenings difference support fixation precast beam shell 1 and precast floor slab bed die 2;
2) reserved steel bar 4 with precast floor slab bed die 2 is inserted in the notch of precast beam shell 1, in precast beam shell 1, lays the also main muscle 5 of colligation clamped beam then;
3) above precast floor slab bed die 2, lay and fixing upper strata bearing reinforcing bar 6; And the upper strata bearing reinforcing bar 6 on the adjacent floor bottom mould 2 is connected into integral body through connecting reinforcement 7; Wherein, connecting reinforcement 7 is staggered into netted and through being welded to connect adjacent upper strata bearing reinforcing bar;
4) cast light weight aggregate concrete 8 on precast beam shell and precast floor slab bed die.
In the above-mentioned steps, flute profile precast beam shell 1 is a mill work, and material can be concrete; Its inside is provided with stirrup; In order to substitute traditional beam forms, the exterior notch of precast beam shell 1 is provided with support rim 3, and support rim 3 is for to be connected the dismountable angle steel on the precast beam shell 1 through bolt; Precast floor slab bed die 2 also is a mill work, is provided with gauze wire cloth in it, in order to substitute traditional floor support shuttering; Upper strata bearing reinforcing bar 6 is prefabricate, and cooperates with precast floor slab bed die 2 sizes.
According to demand, also can on precast beam shell and precast floor slab bed die, pour into a mould ordinary concrete or other materials in the step 4.
Above-described only is preferred implementation of the present invention; Should be understood that for a person skilled in the art; Under the prerequisite that does not break away from technology of the present invention, can also make some distortion and improvement, these can not influence effect and practical applicability that the present invention implements.
