Description
Technical field
The utility model relates to Base hole supporting technology field, is specifically a kind of fish stomach shape steel truss and the fender post of foundation ditch and syndeton of capping beam while adopting fish stomach shape steel truss as foundation ditch support member.
Background technology
Foundation pit supporting system comprises the corral fender pile arranging along margin of foundation pit, is provided with capping beam, and between different capping beams, is provided with traditional multiple tracks concrete or the inner support of steel work on the stake top of each fender post.Traditional multiple tracks inner support can cover whole foundation ditch, blocks digging machine, causes cutting the earth inconvenient.Therefore someone proposes to adopt fish stomach shape steel truss to substitute traditional inner support.As shown in Figure 1, fish stomach shape steel truss forms by a steel main beam 102 parallel with capping beam 101, many shaped steel web members 103 vertical with steel main beam 102, steel strand 104 and for the ground tackle 105 of tensioning steel strand 104.The outer end of every shaped steel web member 103 and steel main beam 102 are fixing, and the inner of every shaped steel web member 103 is provided with steel strand bearing 106, and fish-bellied type steel strand 104 are arranged on steel strand bearing 106.The span of fish stomach shape steel truss is 12～45m, and fish stomach shape steel truss is fixed on to margin of foundation pit through syndeton, and like this, foundation ditch middle body is just completely blank unobstructed, is convenient to cut the earth.
The syndeton of the fish stomach shape steel truss of prior art and the fender post of foundation ditch and capping beam refers to, fish stomach shape steel truss along the length direction of steel main beam every certain span be just provided with one with fender post fixing for carrying the steel corbel of fish stomach shape steel truss.Specifically, bar planting on each fender post, on each fender post, weld again a steel corbel, be about to steel corbel and bar planting welding, then the steel main beam of fish stomach shape steel truss be shelved on each steel corbel and by steel main beam and steel corbel welding or be spirally connected fixing.
There is following defect in above-mentioned syndeton: the one, and the steel corbel of carrying steel main beam belongs to compressed member, and its stock utilization is relatively low, is guaranteed strength and bearing capacity, need to expend great deal of steel and make the large Large Steel bracket of the large quality of volume, and cost is higher; The 2nd, fix each large-scale bracket and need on fender post, at least plant eight and take root in muscle, then by its bracket and bar planting welding, and steel main beam also must be spirally connected one by one or weld with each bracket, installation process workload is huge loaded down with trivial details, wastes time and energy; The 3rd, unloading process need to cut away all bar plantings, and by steel main beam and the cutting of each steel corbel or dismounting, the same loaded down with trivial details effort of process, and, it is often easily to damage bracket and steel main beam, the difficulty that increase utilizes again that the welding position of steel corbel and steel main beam is cut open; The 4th, between steel corbel and steel main beam, belong to and be rigidly connected, its bearing capacity cannot regulate.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of and can save material, reduces costs, mounts and dismounts all syndetons of the fish stomach shape steel truss of time saving and energy saving, the foundation ditch that can not damage link, can again utilize.
Technical solution of the present utility model is, a kind of syndeton of fish stomach shape steel truss of foundation ditch is provided, it comprises many group coupling assemblings, every group of coupling assembling comprises a steel corbel on the fender post that is fixed on foundation ditch, every group of coupling assembling also comprises the montant on a reinforcing bar diagonal member and a removable capping beam that is connected to foundation ditch, the steel main beam of fish stomach shape steel truss is shelved on steel corbel, the upper end of reinforcing bar diagonal member is connected with montant is removable, removable a connection of shaped steel web member of the lower end of reinforcing bar diagonal member and fish stomach shape steel truss.
The syndeton of the fish stomach shape steel truss of the utility model foundation ditch compared with prior art, has the following advantages and effect:
Due to this syndeton is to adopt reinforcing bar diagonal member as main stressed member, and steel corbel has been the accessory of subordinate role, this syndeton is mainly the compressed member of tensional element rather than prior art, therefore stock utilization is higher, guaranteeing under the prerequisite of equality strength and bearing capacity, the weight and volume of reinforcing bar diagonal member and steel corbel will be much smaller than the weight and volume of prior art Large Steel bracket, significantly reduced the amount of expending just now, save cost, reduced cost; And, because steel corbel is accessory, volume mass is little, and during installation, each steel corbel only needs two to take root in muscle and can fix, rather than of the prior art eight take root in muscle, therefore easy to assembly, between each steel corbel and the steel main beam of fish stomach shape steel truss, only shelve still more, and without welding or being spirally connected, further simplified assembling process, compared to existing technology, obviously time saving and energy saving; Equally, unloading process is also without cutting or disassemble the welding between steel main beam and each steel corbel or be spirally connected, and also only needs to cut two when steel corbel is dismantled from fender post and take root in muscle, thus unloading process also facilitate, time saving and energy saving; Equally, dismounting montant and fish stomach shape steel truss, can not damage above-mentioned parts, is convenient to recycle.
As improvement, every group of connector also comprises two pre-embedded bolts and an embedded board, two pre-embedded bolts are through the through hole on embedded board, the lower end of pre-embedded bolt and embedded board are all anchored in capping beam, and the end face of capping beam is stretched out in pre-embedded bolt upper end, and the lower end of montant is welded with one with the end plate of two installing holes, two pre-embedded bolts pass the installing hole of end plate and screw through fastening nut, like this, the installation and removal process of montant only need to screw or unscrew fastening nut, convenient and strength-saving.
As improving again, on shaped steel web member, be welded with the node angle steel of screw rod via hole under a band, the lower end of reinforcing bar diagonal member is passed successively lower screw rod via hole and lower wedge shape parallels and fastening nut and is screwed; Montant is vertical channel-section steel, the web of angle steel is provided with screw rod via hole, and the upper end of reinforcing bar diagonal member is passed successively upper screw rod via hole and upper wedge shape parallels and fastening nut and screwed, like this, the installation and removal process of reinforcing bar diagonal member only need to screw or unscrew fastening nut, convenient and strength-saving; And, during installation, can regulate by the elasticity of adjusting reinforcing bar diagonal member two ends fastening nut the degree of tightness of reinforcing bar diagonal member, and then according to actual conditions, regulate pulling force, the better effects if that whole fish stomach shape steel truss is connected by each reinforcing bar diagonal member.
As also improving, on the web of montant, be welded with a reinforcement channel-section steel vertical with montant, on reinforcement channel-section steel, be also provided with the hole of passing for reinforcing bar diagonal member overlapping with upper screw rod via hole, specifically, strengthen two wing plates of channel-section steel and two wing plates of riser vertical, such design, utilizes two wing plates of strengthening level on channel-section steel, can effectively increase the bend resistance intensity of the web of riser.
