Description

Method for layer-adding reconstruction of wall house of Zangqiang building brickwork blockhouse by adopting wood structure

Technical Field

The invention relates to the technical field of house construction, in particular to a method for building a wooden structure story-adding transformation of a blockhouse with a Tibetan building brickwork, which is particularly suitable for adding stories made on the top of the blockhouse into a wooden frame structure form.

Background

For a long time, due to environmental changes, weather erosion, various social factor interferences and other reasons, masonry in most ancient buildings in China has diseases such as inclination, cracks, shortenings, hollows and the like in different degrees, and the long-term safety of the ancient buildings is seriously threatened. However, for a long time, as the environment changes, the wind and rain erodes and even some artificial damages, the masonry walls in many ancient buildings are accompanied by damages, damages and even collapse in different degrees. The pillbox house group of the Zangqiang building is different from the general building, and the history and significance borne by the back of the pillbox house group are great. In order to completely inherit and express the history and the humanistic connotation contained in the blockhouse of the Zangqiang building, the ancient building is repaired and reinforced through a correct mode method, and necessary reconstruction is performed for improving the use function.

The layer-adding transformation is a common function improvement mode, when the layer-adding transformation is transformed, necessary local reinforcement needs to be performed in advance, and necessary reinforcement needs to be performed on the stress application of the layer-adding transformation. When the requirement of structure reinforcement is met, the basic principle of 'old as old' ancient architecture renovation is combined, the style of the outer facade is kept consistent, and the cultural relic value of the member can not be damaged.

Through to the present impaired pillbox room immature soil stone masonry wall body failure mode analysis discovery of consolidating, the stress condition is more complicated during the brickwork atress, and causes the building block to destroy the leading cause and mainly be, under the pressurized state, because brickwork surface unevenness and mortar joint thickness and closely knit degree are inhomogeneous, and is inhomogeneous to single building block atress, two face bearing capacity can not correspond each other about making the building block, and the building block is inside to produce bending stress and shear stress. Blockhouse is through century, and brickwork intensity is not high when owing to build, and frequently receives stormy weather to attack and the change of humiture, basis subside etc. all can cause the stone wall body damaged, and these losses all can reduce the whole bearing capacity of structure, lead to the structure to take place local destruction under the earthquake action, and the continuity collapses even, so high-efficient practical local reinforcement method is the important problem of solving first in the time of increasing the layer transformation.

With the rapid development of the storey-adding reconstruction technology of buildings in recent years, the following are more common: the method comprises a direct storey adding scheme of a brick-concrete house, a direct storey adding scheme of a multi-storey internal frame structure house, a direct storey adding scheme of a multi-storey full frame structure house, a direct storey adding scheme of a bottom layer full frame structure house, an outer sleeve structure storey adding scheme, an outer expansion connection type or inner shear wall arrangement scheme, an inner column type outer sleeve frame storey adding scheme and the like. However, the methods are difficult to be directly used for storey-adding reconstruction of the ancient building stone-built structure of the Tibetan Qiang, and suitability technology change is needed to ensure the safety of the storey-adding reconstruction of the ancient building stone-built structure.

The utility model with the application number of CN201320407690.3 discloses a direct storey-adding foundation structure of an existing building, wherein a wall-lifting beam passes through the lower part of an original ring beam of the existing building, is supported on newly-added foundation continuous beams at two sides of an original strip foundation and then is transferred to an artificial hole-digging cast-in-place pile; the depth of the artificial hole digging bored concrete pile is determined according to the upper increasing load and the foundation soil layer condition through calculation, the plane position of the artificial hole digging bored concrete pile is close to the original foundation as much as possible, the pile and the original foundation can share the upper load, and meanwhile, the inner-side artificial hole digging pile can be used as a column to increase the underground layer. The storey-adding foundation structure greatly improves the strength, rigidity and stability of the foundation, can meet the storey-adding requirement of the existing building, but is only suitable for the condition that the original building is provided with the ring beam, and a plurality of historic buildings and historical buildings do not have the ring beam to improve the overall working performance of the structure.

The utility model with the application number of CN201820416873.4 discloses a reinforcing and storey-adding reconstruction structure for an old building, which has the technical key points that the outer wall, the inner wall and the floor slab of the first floor of the old building are reinforced by spraying concrete, anchor bars are arranged in a reinforcing layer, and one ends of the anchor bars, which are far away from the wall body, are fixed on a steel plate which is vertical to the axis of the anchor bars; a connecting rod is arranged between the steel plates, and the end part of the connecting rod is provided with a connecting groove matched with the thickness of the steel plates; a one-floor placing room is additionally built on the top floor of the old building, but the old building is convenient for people to place after being reinforced, floor-added and modified. However, the technology does not describe the specific construction measures for building a house and a bottom bearing wall on the top layer of the building, and the specific construction measures are the technical key of storey-adding transformation.

The utility model with the application number of CN201921785150.2 discloses a detachable and reinforced storey-adding reconstruction structure of a special-shaped roof of an old building, which comprises vertical beams, ring beams and a newly-added roof, wherein the vertical beams are vertically distributed around the old building, the bottoms of the vertical beams are buried in an independent foundation, and the ring beams are fixedly connected with the vertical beams through bolts; newly-increased roof is fixed in the top of old building, and reinforced (rfd) layer-adding transformation structure can be dismantled to old building dysmorphism roof, according to the special-shaped roof of difference, the local spatial structure that increases has kept former building landscape, and construction simple to operate does not influence the use and the structure of old building, and the daylighting of former adjacent building can not be destroyed to the unique design in independent space, has enlarged the usage space of original building simultaneously. However, the ring beam and the vertical beam are connected only through the bolts in the technology, and the structural stability of the newly added floor arranged in the connection and reinforcement mode is to be examined.

From last, when current storey-adding method is applied to the irregular wall stone masonry building of raw soil seam, have certain not enough or the technique and lack the pertinence, and vertical biography power component can't effectively be connected with original structure, hardly makes storey-adding part and substructure combine into whole organically, if need combine pillbox room characteristics, then need carry out the suitability technical change.
