Embodiment 1
[0049] see Figure 1-Figure 6 , a UHPC temporary prefabricated house in an earthquake area provided by this embodiment includes a base plate, a UHPC prestressed wall 1 , a UHPC ribbed floor 2 and ancillary facilities 3 . The auxiliary facilities 3 include doors and windows, and the doors and windows are all set on the UHPC prestressed wall 1 .
[0050] In this embodiment, the bottom plate is made of concrete.
[0051] The UHPC prestressed wall 1 is fixed on the side of the bottom plate, and the UHPC prestressed wall 1 is provided with ordinary steel bars and prestressed steel bars in the wall, and the prestressed steel bars are fixed in the wall by pretensioning. Using UHPC prestressed wall 1 can effectively improve the overall stability of the wall. The UHPC prestressed wall 1 includes a plurality of UHPC wall panels, and the thickness of the UHPC wall panels is between 100mm and 200mm. The UHPC prestressed wall 1 is formed by splicing a plurality of UHPC wall panels in seq...
Embodiment 2
[0057] It is basically the same as Embodiment 1, except that this embodiment also provides a method for erecting a UHPC temporary prefabricated house in an earthquake area provided by Embodiment 1.
[0058] A method for erecting a UHPC temporary prefabricated house in an earthquake area, comprising the following steps:
[0059] 1. Foundation excavation, foundation treatment, laying out the outline of the prefabricated house, for the temporary construction of the prefabricated house, just ram and compact it directly, or directly choose hard soil as the foundation.
[0060] 2. For foundation construction, pour a layer of 150mm thick C20 concrete.
[0061] 3. Put the installation line, make sure the required size is accurate.
[0062] 4. Lift the UHPC prestressed wall through the lifting device.
[0063] 5. Install the UHPC ribbed slab on the top of the UHPC prestressed wall through the lifting device. If a prefabricated house with upper and lower floors or more than two floor...

Abstract
The invention provides an earthquake area UHPC temporary board room which comprises a UHPC prestressed wall, a UHPC ribbed floor and ancillary facilities, and prestressed reinforcements are arranged in a wall body of the UHPC prestressed wall. The UHPC ribbed floor slab is fixedly positioned at the top of the UHPC prestressed wall. The ancillary facilities comprise a door and a window, and the door and the window are both arranged on the UHPC prestressed wall. The invention further provides an erecting method of the temporary board room. The erecting method comprises the steps that grooving isconducted, and foundation construction is conducted; assembling the prefabricated UHPC prestressed wallboards into a UHPC prestressed wall; covering the top of the UHPC prestressed wall with a fixedUHPC ribbed floor slab; and mounting the door and the window on the UHPC prestressed wallboard. The temporary board room provided by the invention has the advantages of good heat insulation, sound insulation and fire resistance, good wear resistance, recyclability and high economic benefit, and the prestressed wall is adopted, so that the board room is high in overall stability and strong in impact resistance, and is not easy to damage in severe environments such as strong wind, heavy rainfall and earthquakes.
Description
technical field [0001] The invention belongs to the technical field of concrete slab houses for temporary buildings, and relates to a UHPC temporary slab house in an earthquake area and an erection method. Background technique [0002] The traditional prefabricated house is an economical prefabricated house with color steel plate as the skeleton, sandwich panel as the enclosure material, standard modulus series for space combination, and components connected by bolts. It realizes the universal standardization of temporary buildings—it can be assembled and disassembled conveniently and quickly. At the same time, the prefabricated houses are suitable for a wide range of terrain and can be located on hillsides, hills and grasslands. [0003] At present, the mainstream prefabricated houses use color steel plates as the skeleton and sandwich panels as the enclosure materials. Ordinary board houses are light in weight, easy to transport, assemble and disassemble, and are widely u...
