Abstract
The utility model discloses a square steel tube concrete waist rail, by square steel tube, inside concrete, bolthole and steel casing pipe constitute jointly, wherein, square steel tube reserves last side has the injected hole, inside concrete is poured into into by the injected hole, fill in square steel tube's cavity, four sides at two square steel tube connection positions all are equipped with the bolt hole, the outside parcel of connecting the position has the steel casing pipe, processing has the bolt hole on four sides of steel casing pipe, so that be connected with square steel tube, square steel tube's inside and outside both sides processing has penetrating bolthole, so that skyhook. The utility model discloses compare with traditional waist rail, it is not enough to improve current waist rail bearing capacity, construction procedure shortcoming such as loaded down with trivial details, and have material saving, economic benefits advantage such as obvious.
Description
Technical field
The utility model relates to pattern foundation pit supporting structure field, particularly relates to the waist rail used in foundation pit supporting construction.
Background technology
At present, the waist rail used in pattern foundation pit supporting structure, mainly contains girder steel and reinforced concrete beam.Reinforced concrete beam is because rigidity is large, good integrity, and the advantages such as the shape and size in cross section are flexible are widely used, but have from great, the shortcomings such as construction sequence is complicated, and easily occur crack, and the impact of outdoor construction climate is large; The advantages such as girder steel is little owing to conducting oneself with dignity, easy for installation in recent years gradually development and application get up, but the shortcoming such as girder steel is high to connection required precision, and has easy buckle in compression, fire resistance difference.
Summary of the invention
The purpose of this utility model is the problem and the deficiency that overcome existing waist rail, provides a kind of square steel-pipe concrete waist rail, can improve existing waist rail Lack of support, the shortcomings such as construction sequence is loaded down with trivial details, and have saving material, the advantages such as economic benefit is obvious.
The utility model is achieved through the following technical solutions:
A kind of square steel-pipe concrete waist rail, comprise rectangular steel tube, inner concrete, bolthole and steel sleeve, wherein, rectangular steel tube upper side is reserved with injected hole, inner concrete is injected by injected hole, be filled in the cavity of rectangular steel tube, four sides of two rectangular steel tube connecting portions are equipped with bolt hole, the outside of connecting portion is enclosed with steel sleeve, four sides are processed with bolt hole with steel sleeve, to be connected with rectangular steel tube, the inside and outside both sides of rectangular steel tube are processed with penetrating bolthole, so that skyhook.
The advantage of a kind of square steel-pipe concrete waist rail of the utility model:
(1) steel pipe and concrete acting in conjunction, the rigidity of structure increases, and anti-surrender ability strengthens, and bearing capacity is improved;
(2) part of concrete filled steel tube waist rail is less, simple structure, saving material, remarkable in economical benefits;
(3) steel pipe can bear load and the construction weight of construction stage, and work progress is less by concrete curing time effects.
The implementation method of a kind of square steel-pipe concrete waist rail of the utility model is: first, offer the reserving holes such as injected hole, bolt hole and bolthole at rectangular steel tube upper side; Then, by lifting steel pipes to waist rail installation site, adopt A-frame to carry out temporary support in advance, adopt steel sleeve to connect between multistage rectangular steel tube, connected mode is that bolt connects; Finally, carried out the operation of skyhook by bolthole, after tightening anchor head, fixing rectangular steel tube, inject concrete and tamping by injected hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of square steel-pipe concrete waist rail of the utility model.
Fig. 2 is scheme of installation of the present utility model.
Marginal data: 1-rectangular steel tube; 2-inner concrete; 3-bolthole; 4-steel sleeve; 5-bolt hole; 6-injected hole; 7-A-frame; 8-backing plate; 9-anchor head; 10-anchor pole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated:
A kind of square steel-pipe concrete waist rail is as shown in Figure 1 made up of rectangular steel tube 1, inner concrete 2, bolthole 3 and steel sleeve 4.Described rectangular steel tube 1 upper side is reserved with injected hole 6, is the entrance of inner concrete 2, and four sides of two rectangular steel tube 1 connecting portions are equipped with bolt hole 5; Described inner concrete 2 is injected by injected hole 6, is filled in rectangular steel tube 1 cavity; Described bolthole 3 symmetrical machining two sides inside and outside rectangular steel tube 1, so that skyhook 10; 4 four sides are processed with bolt hole 5 with described steel sleeve, and be wrapped in the connecting portion of two rectangular steel tubes 1, connected mode can be with bolts.
As shown in Figure 2, during installation, first on rectangular steel tube 1, offer the reserving holes such as injected hole 6, bolt hole 5 and bolthole 3; Then, lifted by steel pipe 1 to waist rail installation site, adopt A-frame 7 to carry out temporary support in advance, adopt steel sleeve 4 to connect between multistage rectangular steel tube 1, connected mode is that bolt connects; Finally, carried out the operation of skyhook 10 by bolthole 3, after tightening anchor head 9, fixing rectangular steel tube 1, inject concrete and tamping by injected hole 6.
Claims (1)
