Description
Technical field
The utility model relates to a kind of prefabricated assembling reinforced concrete shear wall plate.
Background technology
In the construction of current prefabrication and assembly construction Shear Wall Residential system, precast and assembled reinforced concrete shear wall slab when mounted, the control of absolute altitude is generally adopt between precast and assembled reinforced concrete shear wall slab and substrate, add steel plate washer or pre-set grey muscle, and these two kinds of methods exist following problem:
1, adopt the height regulation method adding steel plate washer between precast and assembled reinforced concrete shear wall slab and substrate, absolute altitude cannot accurately control, and pad is easily shifted in the installation process of prefabricated panel, so error can be caused to increase.
2, adopt the method pre-setting grey muscle between prefabricated panel and substrate, need solidify until grey muscle and just can carry out the installation of prefabricated panel after reaching some strength, so delayed construction speed.
Utility model content
The utility model is for the purpose of the installation accuracy improving precast and assembled reinforced concrete shear wall slab and speed, a kind of height-adjustable precast and assembled reinforced concrete shear wall slab is provided, solve in the construction of prefabrication and assembly construction Shear Wall Residential system, the technical problem that the bad control of accuracy of absolute altitude when mounted of precast and assembled reinforced concrete shear wall slab, construction speed are slow.
For achieving the above object, the utility model adopts following technical scheme: a kind of height-adjustable precast and assembled reinforced concrete shear wall slab, comprise precast and assembled reinforced concrete shear wall slab, it is characterized in that: on the bottom surface of precast and assembled reinforced concrete shear wall slab, be embedded with at least two built-in fittings, described built-in fitting is made up of anchor plate and tapped sleeve pipe, wherein the soffit of anchor plate and the upper end of tapped sleeve pipe are welded to connect, have an adjusting bolt to be upwards inserted in tapped sleeve pipe by the lower end of tapped sleeve pipe and with tapped sleeve pipe screwed connection.
Preferably, the plane at the place, lower surface of described tapped sleeve pipe can higher than the plane at the place, bottom surface of precast and assembled reinforced concrete shear wall slab, the bottom surface of precast and assembled reinforced concrete shear wall slab has the hole communicated with tapped sleeve pipe, described adjusting bolt from the bottom to top through behind hole, be inserted in tapped sleeve pipe and with tapped sleeve pipe screwed connection.
Preferably, described hole can become large by diameter from top to bottom gradually.
Preferably, the bottom surface of described precast and assembled reinforced concrete shear wall slab is embedded with two built-in fittings.
Compared with prior art the utility model has following characteristics and beneficial effect:
1, the installation accuracy of height-adjustable precast and assembled reinforced concrete shear wall slab is high, can ensure that absolute altitude when prefabrication and assembly construction shear wall slab is installed accurately controls, namely by screw-in and the back-out adjusting elevation of adjusting bolt, make the adjustment of the absolute altitude of precast and assembled reinforced concrete shear wall slab have continuity, accurately can control the installed height mark of precast and assembled reinforced concrete shear wall slab.
2, height-adjustable precast and assembled reinforced concrete shear wall slab can Fast Installation, easy construction, efficient, is particularly suitable for the construction of prefabrication and assembly construction Shear Wall Residential.Compared with traditional technique, one is that the mounting method of height-adjustable precast and assembled reinforced concrete shear wall slab optimizes construction technology, decrease working procedure, make construction more convenient and quick, improve efficiency of construction, two is in the mounting method of height-adjustable precast and assembled reinforced concrete shear wall slab, elevation adjusting device is integrated in precast and assembled reinforced concrete intralamellar part, eliminate and make the intermediate step such as pad and grey muscle, shorten the construction period that prefabricated panel is installed.
3, height-adjustable precast and assembled reinforced concrete shear wall slab to be mounted to power high, and after height-adjustable precast and assembled reinforced concrete shear wall slab installation in position, spanner can be used to finely tune absolute altitude, the construction delay that avoiding does over again causes.
4, height-adjustable precast and assembled reinforced concrete shear wall slab reasonable in design, manufacture craft is simple, and cost is lower.By the mode of embedded iron parts in common precast and assembled reinforced concrete shear wall slab, can reach the adjustable for height object of precast and assembled reinforced concrete shear wall slab, in addition, steel plate and sleeve are as the material preparing built-in fitting, the cost of material is low, and manufacture craft is simple.

Detailed description of the invention
Embodiment is see shown in Fig. 1-5, this height-adjustable precast and assembled reinforced concrete shear wall slab, comprise precast and assembled reinforced concrete shear wall slab 1, it is characterized in that: on the bottom surface of precast and assembled reinforced concrete shear wall slab 1, be embedded with at least two built-in fittings 2, described built-in fitting is made up of anchor plate 2.1 and tapped sleeve pipe 2.2, wherein the soffit of anchor plate 2.1 and the upper end of tapped sleeve pipe 2.2 are welded to connect, have an adjusting bolt 3 to be upwards inserted in tapped sleeve pipe 2.2 by the lower end of tapped sleeve pipe 2.2 and with the screwed connection of tapped sleeve pipe 2.2.Adjusting bolt 3 is screwed in the tapped sleeve pipe 2.2 of described built-in fitting 2, by change adjusting bolt 3 be screwed into the setting height(from bottom) that the degree of depth just can finely tune precast and assembled reinforced concrete shear wall slab 1.
The plane at the place, lower surface of described tapped sleeve pipe 2.2 is higher than the plane at the place, bottom surface of precast and assembled reinforced concrete shear wall slab 1; the bottom surface of precast and assembled reinforced concrete shear wall slab 1 has the hole 4 communicated with tapped sleeve pipe 2.2; effect is protection built-in fitting; hole 4 from top to bottom diameter becomes large gradually, described adjusting bolt 3 from the bottom to top through behind hole 4, to be again inserted in tapped sleeve pipe 2.2 and with the screwed connection of tapped sleeve pipe 2.2.
