Abstract
The utility model relates to an elevator beam plate type base structure for building, in particular to an overhead deep foundation pit crossing construction elevator beam plate type base structure. The base structure comprises an elevator base beam plate and is characterized in that the elevator base beam plate is horizontally located between a deep foundation pit slope protection side and a shear wall of a building, one end of the elevator base beam plate is fixed with the shear wall, and the other end of the elevator base beam plate is fixed with independent bases arranged on the deep foundation pit slope protection side. The base structure has the advantage that too large sedimentation and uneven sedimentation of a construction elevator base are effectively prevented, deformation, overturning and collapse accidents are avoided, safety use of a construction elevator is ensured, and economical benefit is created indirectly; the problem that the elevator base cannot be constructed due to the fact that outdoor backfill soil compaction time is not enough is solved, elevator installation is not affected, the main building project can be constructed on schedule, the previous preparation working time of the building project is greatly reduced, and the project construction progress is improved.
Description
Technical field
The utility model relates to a kind of construction elevator beam and slab type foundation structure for building, is specifically related to a kind of construction elevator beam and slab type foundation structure of overhead crossing deep foundation ditch.
Background technology
Highrise building is designed with basement mostly, so foundation depth generally exceedes 6m, some even reaches 15-20m.Construction elevator is arranged on outdoor deep foundation ditch position mostly, if be arranged in deep foundation ditch backfill, can because banket that the degree of depth is excessive, the backfill time is short, compaction quality causes the excessive or differential settlement of depression not, particularly backfill sedimentation in rainy season maximum can reach 10-15cm, cause excessive can not the use of construction elevator distortion, when serious, there is the security incidents such as construction elevator topples, collapses, serious threat construction safety.If start to do elevator basis from foundation ditch bottom hard soil layer, the first long construction period, too high very uneconomical of the second cost.
Utility model content
According to above the deficiencies in the prior art, the utility model proposes a kind of construction elevator beam and slab type foundation structure of overhead crossing deep foundation ditch, by the built on stilts construction elevator beam and slab type foundation structure of building between the shear wall at building and foundation pit slope protection limit, in case non-return bankets, the excessive or differential settlement of sedimentation causes the security incidents such as construction elevator is out of shape, topples, collapses, and can reduce construction costs, reduction of erection time.
The construction elevator beam and slab type foundation structure of a kind of overhead crossing deep foundation ditch described in the utility model, comprise elevator basis beam slab, elevator grade beam plate level is between deep foundation ditch bank protection limit and the shear wall of building, elevator beam slab one end, basis and shear wall fix, and on the other end and deep foundation ditch bank protection limit, symmetrically arranged single footing fixes.
Wherein, single footing is preferably greater than 50cm apart from the distance of outer, deep foundation ditch bank protection limit.
The both sides girder of elevator basis beam slab, near one end, single footing, preferably arranges linking beam perpendicular to girder, thereby ensures beam-ends lateral stability, links back high consistent with girder top mark, and linking beam arrangement of reinforcement meets structure and requires.
Beam slab one end, elevator basis preferably fixes by adopting bracket, built-in connection or bar planting to be connected with shear wall.Before basic engineering, first will be according to the position incorporation engineering entity of construction elevator yet to be built, determine the connected mode of elevator basis beam slab and exterior wall.If this exterior wall top, place is hole (building a wall afterwards or door opening), directly beam is shelved on to exterior wall top, and stretching into certain length inside body of wall, length is not less than design code value (be about the half of thickness of wall body, cut and be not less than the width that designs beam section).If this place is shear wall entity, need rear bar planting, first according to the high bottom elevation of determining beam and slab structure of former earth foundation top mark, then by the setting-out one by one of bar planting position, after bar planting, carry out reinforcing bar binding.Also can in the time of shear wall construction, stay and establish bracket or built-in connection.
When construction, carry out according to following steps: design elevator basis beam slab arrangement of reinforcement and sectional dimension, and carry out stressed checking computations-construction basis on deep foundation pit slope original soil-install support frame of beam and board formwork-according to examination before beam slab design reinforcement and sectional dimension assembling reinforcement reinforcing template-set aside pre-embedded anchoring piece the operation of examinations-concreting-maintenance-installation elevator-construction elevator.
The beneficial effect that the utility model has is: (1) can prevent the generation of the construction elevator excessive sedimentation in basis and differential settlement effectively, avoided distortion, toppled, collapse accident, ensure the safe handling of construction elevator, indirectly created economic benefit; (2) no longer inadequate because of the outdoor backfill compacting time, cannot construction elevator basis, affect elevator and install, cause main body masonry project to construct as scheduled, greatly reduce the preliminary preparation time of masonry project, improved engineering construction progress.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram of elevator beam slab one end, basis and shear wall;
In figure, 1, elevator basis beam slab 2, shear wall 3, deep foundation ditch bank protection limit 4, single footing 5, girder 6, linking beam 7, bracket.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described further.
Embodiment 1:
As depicted in figs. 1 and 2, a kind of construction elevator beam and slab type foundation structure of overhead crossing deep foundation ditch, comprise elevator basis beam slab 1, elevator basis beam slab 1 level is between deep foundation ditch bank protection limit 3 and the shear wall 2 of building, elevator beam slab 1 one end, basis and shear wall 2 fix, and on the other end and deep foundation ditch bank protection limit 3, symmetrically arranged single footing 4 fixes.
Wherein, single footing 4 is greater than 50cm apart from the distance of 3 outers, deep foundation ditch bank protection limit.
The both sides girder 5 of elevator basis beam slab 1, near 4 one end, single footing, arranges linking beam 6 perpendicular to girder 5, thereby ensures beam-ends lateral stability, and linking beam 6 tops are high consistent with girder 5 top marks, and linking beam 6 arrangements of reinforcement meet structure and require.
Beam slab 1 one end, elevator basis fixes by adopting bracket 7 to be connected with shear wall 2.In the time that shear wall 2 is constructed, will stay and establish bracket 7.
