Description
Technical field
The utility model relates to a kind of steel work, especially a kind of steel support structure that is used for supporting foundation ditch.
Background technology
Foundation ditch is the provisional mine pit of building foundation excavation, and foundation ditch belongs to temporary work, and its effect provides a space, makes the operation of building by laying bricks or stones on basis be able to carry out according to the designing institute appointed positions.General foundation ditch all is to excavate to form in existing ground, such as under road, building the subway passage, perhaps on the road face, excavate a subway access, the foundation ditch of Xing Chenging generally all needs steel work and supports when building like this, particularly the foundation ditch two sides are supported, prevent that avalanche from appearring in the foundation ditch side, and support and to carry out support fixation to the concrete casting of foundation ditch metope, so steel support structure uses more and more wider by steel work.
When building viaduct, the construction of bridge floor also needs steel work and supports.
Patent Office of the People's Republic of China has announced a CN2793162Y patent on July 5th, 2006, name is called many diagonal braces, large space opposite supporting type steel support structure.Adopt the tower structure of angle steel formation and weld the bob plate as brace summer around framework, be welded with adpting flange in the end of brace summer, this adpting flange installs mutually by bolt and is formed by connecting.The supporting surface that this steel work supports has only the adpting flange of end, it is exactly much that the face of adpting flange connects much, the diameter of general brace summer is not very big, so the area of supporting surface can be very not big yet, and lifting surface area is little during whole two sides that connect foundation ditch, the whole burden of steel work is heavy, and the length of brace summer also fixes, and can not change, and runs into the width of different foundation ditches, need to change and use different steel work, versatility is poor.
Summary of the invention
It is little that the utility model has solved in the prior art steel work lifting surface area, and whole stressed irrational shortcoming provides a kind of steel support structure that lifting surface area improves force-bearing situation that enlarged.
The utility model has also solved in the prior art need change specification if regulate the length of steel work, and the shortcoming that can not directly regulate provides a kind of steel support structure that can regulate the length of steel work according to the real size needs.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of steel support structure, comprise brace summer and the movable end that is connected with brace summer, the end face of movable end is the massive plate of size greater than brace summer, the plane of massive plate is provided with at least two feets, described feet is according to brace summer center symmetric arrangement, and the end of feet is fixed with gripper shoe.The size of the massive plate of movable end is greater than the size of brace summer, make the connection area of massive plate greater than the connection area of traditional brace summer, thereby optimization force structure, the end of steel support structure adopts feet to support, when being connected on the massive plate, feet can regulate the length of stretching out, thereby adjust the length of brace summer integral body, when the connecting portion in steel support structure and foundation ditch side is on-plane surface, particularly on the cascaded surface, thus by change different feets extension elongation adjust the position of the relative foundation ditch of different feets side.
As preferably, be symmetrically fixed with hollow pin frame on the plane of massive plate, the size of pin frame inside and the size of feet match, and feet extend in the pin frame and fixes.The extension elongation adjustment of feet extend into pin frame inside dimension by adjustment and realizes.
As preferably, feet and pin frame are that square steel is made, upper plate that fixedly is parallel to each other on the plane of massive plate and lower plate, and the pin frame is fixed between upper plate and the lower plate and with upper plate and lower plate and fits.Square steel is directly made feet and pin frame, draws materials conveniently, make simple, the pin frame be fixed on the massive plate and be clipped in upper plate and lower plate between, upper plate and lower plate play booster action to the pin frame, can also the position of pin frame be limited simultaneously.
As preferably, the quantity of the pin frame of feet is two, and the pin frame is fixed on the two ends of the longest distance of massive plate, and the bottom of lower plate is fixed with channel-section steel, and the direction of channel-section steel and feet is perpendicular.The quantity of feet can determine that the centre of massive plate is circular, is extended with fixed part on the axis direction according to the stressing conditions of reality, and massive plate is an overall structure, and longest distance is the length of fixed part place axis direction; Feet is two, increases the span that connects, if the distance between two feets expands the diameter of brace summer to, then feet can be pitched outside the brace summer, forms chi structure; The channel-section steel of lower plate bottom improves the intensity of lower plate, can improve whole holding capacity simultaneously.
As preferably, the feet internal fixation has web, and the webs in two feets are parallel to each other, and the length of web is greater than the degree of depth of feet inside, and an end of web is fixed on the inside of pin frame.Web can be strengthened the bonding strength between feet and the pin frame.
As preferably, the side of web is a step edge, and the size at the two ends of web matches with the size of feet inside and the size of pin frame inside respectively, and the thickness of ladder equals the thickness of feet square steel.Between the size of the size of feet inside and pin frame inside difference in size is arranged, therefore web is made step edge, can be so that web can contact with the pin frame fully with feet.
As preferably, the size of gripper shoe is greater than the size of feet, and the side of gripper shoe two opposite edges edge and feet is fixed with reinforcing rib, and two other side of feet is fixed with thickening plate.The size of gripper shoe is greater than the size of feet, the periphery of reserving gripper shoe can be used for connecting, the gripper shoe of Kuo Daing can be strengthened fixing with reinforcing rib and feet side simultaneously, as preferably, be connected with connecting cylinder between movable end and the brace summer, be fixed with middle plateform between connecting cylinder and the brace summer, the position that connecting cylinder is corresponding with feet in appearance is fixed with some interlaced stringer boards and transverse slat.Massive plate is fixed on the end of brace summer, depends merely on massive plate and connects and may cause strength deficiency, at the appearance of connecting cylinder fixing staggered stringer board and transverse slat massive plate is strengthened, and prevents the massive plate distortion or cracks.
As preferably, transverse slat is trapezoidal totally three, and the centre is a slab, and both sides are thin plate up and down, and the thickness of slab is greater than gauge of sheet, the stringer board and the thin plate vertical fixing of both sides up and down, and slab is vertically fixed on the middle part of stringer board.Stringer board and transverse slat form a shaped as frame structure, and thin plate and back plate form stiffener, improve the intensity that massive plate connects.
Second kind of scheme: also be provided with some reinforcing posts parallel on the plane of massive plate, between the feet with feet.Be fixed with reinforcing post between two feets, preventing that the intensity in the middle of much the causing of span between the feet from reducing, strengthening fixing by reinforcing post.
The beneficial effects of the utility model are: the end of steel support structure is fixedly connected with feet, feet is adjusted length when connecting, can adapt to the support of complicated supporting surface, support distances between the feet is greater than the support distances of traditional brace summer, thus the force-bearing situation of change steel support structure integral body.
