Abstract
The utility model discloses a foundation pit support bracing plate structure comprising a concrete board main body and two groups of parallel transverse steel bars (310 and 320) which are respectively embedded at the upper part and the lower part of the concrete board main body (300); one ends of the two groups of the transverse steel bars are directly anchored into a basement structure (200); and the two groups of transverse steel bars (310 and 320) which are respectively embedded at the upper part and the lower part of the concrete board main body (300) are crossed before being anchored into the basement structure (200) and then are directly anchored into the basement structure (200). The foundation pit support bracing plate structure has the advantages that the connection rigidity of the bracing board and the basement structure is weakened and the stressing state of the bracing board is improved.
Description
Technical field
the utility model relates to technical field of buildings, is specifically related to a kind of bracing of foundation pit fagging structure.
Background technology
Change in the fagging method in
bracing of foundation pit, change the method that the fagging reinforcing bar is connected with fender post (wall), commonly used for adopting the chemically-planted steel bar method to anchor into 15d in fender post or the enclosure wall, promptly 15 of bar diameter length times; The method that is connected with agent structure, commonly used for adopting the embedded bar method directly to anchor into La certain-length in the basement structure.This fagging structure causes fender post or enclosure wall reinforcement planting quantity a lot, and cost is higher; Changing fagging simultaneously has effect of contraction to underground cell structure, has changed to change the fagging stress, also causes easily and changes the fagging crack.
Summary of the invention
the utility model technical problem to be solved is to overcome that fagging cost in the bracing of foundation pit of prior art is high, the problem of technical sophistication; A kind of fagging construction of conveniently changing is provided; It is stressed that fagging is changed in simplification, guarantees the bracing of foundation pit fagging structure that its actual loading and design conform to.
are in order to solve these problems of the prior art; The technical scheme that the utility model provides is: bracing of foundation pit fagging structure; Comprise the concrete slab body; Be embedded in horizontal two groups of reinforcing bars of concrete slab upper part of body and bottom respectively, and described horizontal two groups of reinforcing bar one ends directly anchor into basement structure, it is characterized in that; The said horizontal two groups of reinforcing bars that are embedded in concrete slab upper part of body and bottom intersected before anchoring into basement structure, and then directly anchored into basement structure.
preferably, the angle that horizontal two groups of reinforcing bars of said upper and lower intersect is preferably 45 degree, and directly anchors into the preferred 15cm ~ 25cm of basement structure length.
preferably, establish at concrete slab body middle part one with the oblique lacing wire of the interior reinforcing bar welding of fender post or enclosure wall.
preferably, said oblique lacing wire and said concrete slab body angle be preferably 45 the degree.
preferably, said oblique lacing wire in the concrete slab body, extend to straight down nearly bottom again horizontal direction towards the bending of fender post or enclosure wall.
preferably, and the other end of horizontal two groups of reinforcing bars of said upper and lower does not anchor in fender post or the enclosure wall.
The advantage of the foundation pit enclosure structure of the utility model is:
are the bracing of foundation pit fagging structure of the utility model 1.; Its fagging reinforcing bar and fender post (wall) ways of connecting are: by the interior chemically-planted steel bar of stake (wall); Change the oblique lacing wire that is provided with the interior reinforcing bar welding of stake (wall) into, change fagging and fender post (wall); Its fagging reinforcing bar and basement structure ways of connecting are: by the reinforcing bar of pre-buried level, change the reinforcing bar of pre-buried diagonal cross into, the coupling stiffness of fagging and basement structure is changed in reduction, has improved and has changed the fagging stress.
The bracing of foundation pit fagging structure of the utility model is 2. adopted in
, can practice thrift and change the support duration of a project at least 20%, practices thrift and changes support construction costs at least 15%.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the bracing of foundation pit fagging structural representation of prior art;
Fig. 2 is the sketch map of the bracing of foundation pit fagging structure of the utility model.
wherein, 100 is fender post or enclosure wall, 200 is basement structure; 300 is the concrete slab body; 310 be (in the concrete slab body) upper lateral reinforcing bar, 320 be (in the concrete slab body) the lower, transverse reinforcing bar, 303 are and two groups of above-mentioned longitudinal reinforcements that transverse reinforcement is vertical; 330 is oblique lacing wire, and 331 is the bending part of oblique lacing wire in concrete slab.
The specific embodiment
further specify such scheme below in conjunction with specific embodiment.Should be understood that these embodiment are used to the utility model is described and the scope that is not limited to limit the utility model.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
bracing of foundation pit fagging structure; Comprise the concrete slab body; Be embedded in horizontal two groups of reinforcing bars 310,320 of the upper and lower of concrete slab body 300 respectively; Also comprise the vertical two group reinforcing bars 303 vertical with two groups of above-mentioned transverse reinforcements; And described horizontal two groups of reinforcing bar one ends directly anchor into basement structure 200, and the said horizontal two groups of reinforcing bars 310,320 that are embedded in the upper and lower of concrete slab body 300 intersected before anchoring into basement structure 200, and then directly anchored into basement structure 200; Concrete slab body 300 middle parts establish one with fender post or enclosure wall 100 in the reinforcing bar 110 oblique lacing wire 330 of welding; And the other end of horizontal two groups of reinforcing bars 310,320 of said upper and lower does not anchor in fender post or the enclosure wall, has practiced thrift like this and has changed support engineering time and cost.
Among one embodiment of
the utility model, the angle that horizontal two groups of reinforcing bars 310,320 of upper and lower intersect is preferably 45 degree, and directly anchors into the preferred 15cm ~ 25cm of basement structure length.Oblique lacing wire 330 is preferably 45 degree with said concrete slab body 300 angles.
In one preferred embodiment of
the utility model, said oblique lacing wire 330 in concrete slab body 300, extend to straight down nearly bottom again horizontal direction towards 100 bendings of fender post or enclosure wall.
above advantage that shows and described basic principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.
