The foundation shock insulation method is economic and reasonable and safe and reliable, and has broad application prospects.
Description
Technical field
The present invention relates to a kind of shock isolating pedestal brick and mix fixing structure and support and change method is installed, mainly utilize the cylindrical prefabricated pin key beam of concrete filled steel tube that shock insulation is carried out on the basis and process, belong to the seismic hardening field.
Background technology
The pin key beam is equivalent to be inserted in the pin key in the load bearing wall, and the vertical load of structure is passed to the shoulder beam by it.Pin key beam section in the conventional method is shaped as rectangle, adopts cast-in-place concrete construction technique.For guaranteeing that the pin key beam is connected with the shoulder beam, stay bar splice outward; For guaranteeing construction, template installation, it is larger that pin key beam dimension of opening should be opened.There is following shortcoming in it:
1, the masonry structure before the eighties is set up defences without antidetonation, do not establish constructional column and collar tie beam, generally there is not the ground collar tie beam yet, and the intensity of brick and mortar is usually lower, for guaranteeing to transmit reliably the superstructure load, can not cause again because of brick wall pressure-bearing deficiency, cause structural deterioration, so the common spacing of pin key beam is less, generally establish a pin key beam every 500～700mm, and pin key deck-siding 250mm, the common wide 300mm that is not less than in hole, the hole is intensive or the method that punches is improper, can cause wall body slit to be communicated with, and causes structural deterioration.
2, the pin key beam is Cast-in-place concrete, sometimes adopts the interval to punch for guaranteeing construction safety, in batches the method for pouring construction.Long because of the concrete cure cycle, this has just affected construction speed greatly, causes engineering not construct continuously.
3, consider in the design that the pin key beam is connected with steel concrete shoulder the reliable of beam, generally will get rid of in advance anchor bar, the more formwork supporting plate difficulty that causes of these dowel quantity.
4, because pin key beam hole is offered and can't be accomplished very standard, but pin key beam concrete must be full of the hole, can not stay the space, also causes difficulty to concrete construction.
5, because the quantity of pin key beam is a lot, and problem is also a lot of in the construction, has had a strong impact on the quality control difficulty of base isolation reinforcement and prolonged construction period.This is key and Key technique problem that Seismic Isolation of Isolation Layer arranges.
Summary of the invention
The present invention is in order to overcome the deficiency of conventional method, having proposed a kind of shock isolating pedestal brick mixes fixing structure and support and change method is installed, its installation that can solve better shock isolating pedestal in the base isolation with insert a difficult problem, a kind of simple in structure, economical rationality, actual effectively Shockproof reinforcing method are provided.
To achieve these goals, the present invention has taked following technical scheme:
A kind of shock isolating pedestal brick is mixed fixing structure, comprise ground collar tie beam, prefabricated pin key beam, upper shoulder beam, lower shoulder beam, upper sealing plate, lower shrouding, shock isolating pedestal, wherein, prefabricated pin key beam is divided into prefabricated pin key beam and lower prefabricated pin key beam, the load bearing wall of collar tie beam below, described ground is divided into upper and lower two parts, is provided with shock isolating pedestal between upper and lower two parts load bearing wall; Be arranged at intervals with prefabricated pin key beam hole on the load bearing wall of top, be inserted with prefabricated pin key beam in the hole; Be arranged at intervals with prefabricated pin key beam hole on the load bearing wall of bottom, be inserted with lower prefabricated pin key beam in the hole; Upper and lower prefabricated pin key beam all stretches out the load bearing wall both sides; Many upper prefabricated pin key beams that stretch out connect as one by upper shoulder beam, and many lower prefabricated pin key beams that stretch out connect as one by lower shoulder beam; Be respectively arranged with upper sealing plate and lower shrouding between shock isolating pedestal and the upper and lower shoulder beam.
Further, described prefabricated pin key beam is the cylindrical prefabricated pin key beam of concrete filled steel tube.
