Description
Technical field
The utility model relates to the foundation pit construction technology in field of civil engineering, be specifically a kind of when pushing up road steel pipe support and needing to be embedded in concrete of basement top board for connecting the muscle formula bracket of top road steel pipe support and foundation pit bracing piling wall.
Background technology
Along with the extensive rise of subway engineering and underground space engineering construction, the construction technology also development of foundation ditch and basement structure.Traditional foundation ditch and the construction method of basement structure are, piling wall is gone along with sb. to guard him in first construction, then capping beam is built going along with sb. to guard him on piling wall, again at capping beam with road, fixing top, absolute altitude place steel pipe support, dig foundation ditch under then starting, excavate lower one deck and enclose purlin height this layer of then constructing and enclose purlin and the inner support with absolute altitude, then dig under continuing, until under dig the end, hole, build the base plate of basement structure, then up to construct outer wall of basement from base plate.When outer wall of basement constructs capping beam absolute altitude, in two kinds of situation, first is also in most cases, pre-sets support replacement beam in the below of capping beam height, and Ze Jiangding road steel pipe support is dismantled, then at capping beam absolute altitude place construction basement roof.But, at some in particular cases, support replacement beam cannot be set, such as this basement side is the soil body and opposite side is the Metro Space having hollowed out and built up, cannot stress balance be reached due to both sides therefore support replacement beam cannot be set, now, just can not only remove top road steel pipe support but imbed permanent for road, top steel pipe support in basement roof.But this generates following technical barrier.
First the connected mode between top road steel pipe support and two capping beams at its two ends is analyzed, first capping beam is fixed with steel corbel, and the two ends of Mei Gending road steel pipe support are first shelved on two steel corbels, again be positioned at that two capping beams that support two ends are welded and fixed, the volume of steel corbel is large, if do not remove steel corbel and basement roof of directly constructing, so basement roof reinforcing bar can be stopped and and cannot go along with sb. to guard him piling wall and be connected and fixed with capping beam by steel corbel; And installation and removal steel corbel all can cause, and efficiency of construction reduces, expense increases.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of and is connected when needing can not to stop when top road steel pipe support is imbedded basement roof the reinforcing bar of basement roof and capping beam and going along with sb. to guard him piling wall, can meets again the muscle formula bracket pushing up the needs shelved safely when road steel pipe support is installed.
Technical solution of the present utility model is, one effective reinforcement formula bracket is provided, it comprises two anchor bars, a U-shaped holder muscle and one piece of pre-embedded steel slab, every root anchor bar erects muscle, anchoring diagonal bar by anchoring, exposes horizontal bar and exposes perpendicular muscle and is connected in sequence, and muscle is erected in anchoring and anchoring diagonal bar is positioned at capping beam concrete; U-shaped holder muscle comprises two perpendicular sections and a crosspiece, and crosspiece two ends are erected a section lower end with two respectively and fixed; Two perpendicular section upper ends of U-shaped holder muscle are fixed with the lower end of exposing perpendicular muscle of two anchor bars respectively; Pre-embedded steel slab is fixed on capping beam medial surface, and pre-embedded steel slab is welded and fixed with one end of road, top steel pipe support; One end of road, top steel pipe support is shelved on the crosspiece of U-shaped holder muscle.
Utilize this muscle formula bracket to construct and push up the method for road steel pipe support and top board, its step comprises:
Piling wall is gone along with sb. to guard him in a, construction;
B, colligation capping beam reinforcing bar set up each side template, and the anchoring of two anchor bars is erected in muscle and anchoring diagonal bar insertion template, and exposing horizontal bar and exposing perpendicular muscle of anchor bar is all positioned at outside template, and inner side template pre-embedded steel slab being touched capping beam is placed;
C, build capping beam concrete, make the anchoring of anchor bar erect muscle and anchoring diagonal bar is anchored in capping beam concrete, and at capping beam end face and the gap of exposing between horizontal bar and capping beam medial surface and the gap place mat asphaltic felt that exposes between perpendicular muscle;
Each side template of d, capping beam of dismantling, makes pre-embedded steel slab be exposed to the inner surface of capping beam;
E, the upper end of U-shaped holder muscle two section of erecting and two of two anchor bars are exposed perpendicular muscle lower end be spirally connected or weld;
F, the two ends of top road steel pipe support are shelved on the crosspiece of U-shaped holder muscle of two muscle formula brackets respectively, insert wedge shape band iron in gap between the pre-embedded steel slab of the muscle formula bracket that every one end of steel pipe support, Bing Ding road and this end are shelved, Bing Jiangding road steel pipe support, pre-embedded steel slab and wedge shape band iron are between the two welded and fixed;
G, under dig foundation ditch, construction basement bottom board;
H, set up roof plate template, colligation roof steel bar, and the steel reinforcement abutting joints of roof steel bar and capping beam is fixed; Build concrete roof.
The utility model muscle formula bracket compared with prior art, has the following advantages and effect:
First, this muscle formula bracket is installed more obvious than steel corbel simpler, only needs when building capping beam, the anchoring of anchor bar to be erected muscle and imbed capping beam concrete together with anchoring diagonal bar and pre-embedded steel slab, then be connected with anchor bar by U-shaped holder muscle, save man-hour, raise the efficiency; And the more important thing is, muscle formula bracket is meeting under the prerequisite of shelving intensity required by the road steel pipe support of top and bearing capacity, and volume ratio steel corbel is much little, can not stop the reinforcing bar of basement roof, facilitates the main muscle of basement roof and the steel reinforcement abutting joints of capping beam; And muscle formula bracket is permanent imbeds basement roof for this, without the need to removing, raises the efficiency further, shortening man-hour; Moreover cost and the consumable quantity of this muscle formula bracket are starkly lower than steel corbel, save construction costs, economical rationality.
