SU1560691A1 - Large-panel building - Google Patents

Abstract

The invention relates to large-panel buildings. The purpose of the invention is to increase the effectiveness of building protection when erecting it on subsiding grounds. In a large-panel, rigid-zero building on the upper floor there is a spatial rigid system of vertical diaphragms, connected to the cover plates and panels of the upper floor by rigid and flexible connections. The latter are installed in the vertical joints of the wall panels and are anchored in the basement part or in the foundations and in the spatial rigid system of vertical diaphragms. 3 hp ff, 7 ill.

Description

The invention relates to housing and civil construction and can be used in the construction of low-rise large-panel buildings, such as kindergartens and schools, and multi-story large-panel public buildings of increased length in difficult ground conditions.

The purpose of the invention is to increase the efficiency of building protection when erecting it on a subsiding base.

Figure 1 shows a large-panel building; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1; figure 4 is a fragment of a system of vertical diaphragms of prefabricated elements; figure 5 is the same, of monolithic reinforced concrete; figure 6 and 7 - the same, the implementation of prefabricated monolithic version with monolithic v

reinforced concrete som respectively on top and bottom.

The large-panel building includes foundations 1 and panels 2 of the walls of the basement part 3, rigidly interconnected to form a hard zero, panels of 4 load-bearing walls with hidden reinforcement on themselves 5, rigidly connected with floor slabs 6 and coatings 7.

The building is equipped with a spatial rigid system of vertical diaphragms 8 located above the covering plates 7 along the axes of the supporting walls 4 and connected to the covering plates 7 and the wall panels 4 of the upper floor 9 by means of rigid connections 10, which perceive horizontal shear forces.

The panels 2 of the walls of the basement part 3 of the building can be connected to the overlapping plates of the bis panels of the walls of the lower floor by means of rigid connections 10, which perceive horizontal shear forces.

The building can also be equipped with flexible connections 11, located in the vertical joints 12 of the panels 4 of the supporting walls and anchored in the basement part 3 or in the foundations 1 and in the spatial rigid system of vertical diaphragms 8.

In addition, the building can also be equipped with an additional monolithic core 13, located above or below the spatial rigid system of vertical diaphragms 8.

The connection of the prefabricated elements of the system of cross diaphragms 8 among themselves and with the monolithic sections 13 is carried out by known methods, for example by welding the outlets of the working reinforcement with subsequent monolithing the joint or by connecting the fixings and the monolithic reinforced concrete spikes 13 between the floor slabs.

In case of uneven precipitation of bases, both hard zero and wall bearing structures are involved in the work, the spatial rigid system of intersection diaphragms 8 and the cover plate 7.

The spatial rigid cross-reinforced diaphragm system 8 has significant intrinsic stiffness and absorbs large tensile and compressive forces.

The location of the powerful load-bearing elements of the building (spatial rigid cross system of walls 2 of the base 3 and the base 1 part and the spatial rigid cross system of vertical diaphragms 8 of the crowning part) above and below the spatial box of the building increases its rigidity and its carrying capacity as a whole.

In some cases, the device of a spatial rigid system of diaphragms 8 makes it possible to refuse to reinforce the building with traditional floor systems by themselves 5 and, in addition,

It will remove a number of restrictions on architectural planning decisions. It becomes possible to carry out kinks of the plan (protrusions, zapastan, wall displacement) and change their size over a wide range from small (0.8 m) to large (more than 3 m), which contributes to the diversity of architectural and planning decisions and improvement of technical and economic indicators of large-panel buildings.
