Abstract
The invention discloses a foundation pit enclosure supporting plate structure, which comprises a concrete slab body (300) and two groups of horizontal steel bars (310 and 320) which are embedded on the upper part and the lower part of the concrete slab body (300) and are parallel, wherein one ends of the two groups of horizontal steel bars are directly anchored into a cellar structure (200); and the two groups of horizontal steel bars (310 and 320) which are embedded on the upper part and the lower part of the concrete slab body (300) are crossed before anchoring into the cellar structure (200) and are directly anchored into the cellar structure (200). The foundation pit enclosure supporting plate structure has the advantages that the connecting rigidity of a support replacement plate and the cellar structure is weakened and the stress state of the support replacement plate is improved.
Description
Technical field
The present invention relates to technical field of buildings, be specifically related to a kind of bracing of foundation pit fagging structure.
Background technology
In the support replacement plate method, the method that support replacement slab muscle is connected with fender post (wall) is used always to adopting the chemically-planted steel bar method to anchor into 15d in fender post or the enclosure wall, namely 15 of bar diameter length times in the bracing of foundation pit; 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; The support replacement plate has effect of contraction to underground cell structure simultaneously, has changed support replacement plate stress, also causes the support replacement plank split easily.
Summary of the invention
Technical problem to be solved by this invention is to overcome the problem of fagging cost height, technical sophistication in the bracing of foundation pit of prior art, a kind of support replacement plate construction that makes things convenient for is provided, it is stressed to simplify the support replacement plate, guarantees the bracing of foundation pit fagging structure that its actual loading conforms to design.
In order to solve these problems of the prior art, technical scheme provided by the invention 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 described horizontal two groups of reinforcing bars that are embedded in concrete slab upper part of body and bottom intersected, and then directly anchored into basement structure before anchoring into basement structure.
Preferably, the angle that horizontal two groups of reinforcing bars of described 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, described oblique lacing wire and described concrete slab body angle are preferably 45 degree.
Preferably, described 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 described upper and lower do not anchor in fender post or the enclosure wall.
The advantage of foundation pit enclosure structure of the present invention is:
1. bracing of foundation pit fagging structure of the present invention, its fagging reinforcing bar and fender post (wall) ways of connecting are: by the interior chemically-planted steel bar of stake (wall), change into the oblique lacing wire of welding with interior the reinforcing bar of stake (wall) is set, carry out support replacement plate 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 reduction support replacement plate and basement structure has improved support replacement plate stress.
2. adopt bracing of foundation pit fagging structure of the present invention, can save the support replacement duration of a project at least 20%, save support replacement construction costs at least 15%.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is the bracing of foundation pit fagging structural representation of prior art;
Fig. 2 is the schematic diagram of bracing of foundation pit fagging structure of the present invention.
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
Below in conjunction with specific embodiment such scheme is described further.Should be understood that these embodiment are not limited to limit the scope of the invention for explanation the present invention.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, the described 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 300; 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 horizontal two groups of reinforcing bars 310 of described upper and lower, 320 the other end do not anchor in fender post or the enclosure wall, have saved support replacement engineering time and cost like this.
In one embodiment of the invention, horizontal two groups of reinforcing bars 310 of upper and lower, 320 angles of intersecting are preferably 45 degree, and directly anchor into the preferred 15cm ~ 25cm of basement structure length.Oblique lacing wire 330 and described concrete slab body 300 angles are preferably 45 degree.
In the preferred embodiment of the present invention, described 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.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.
