Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
A kind of box-like basis of beam-board group suitable for work transmission line of the invention, as depicted in figs. 1 and 2, including bottom
Portion's supporting layer, crossbeam frame and column 1, the bottom support layer include the more laths being parallel to each other 2, and lath 2 is strip
The rectangular slab of shape, cross section are also in rectangle, using precast slab, play the effect on the entire basis of support, the quantity of lath 2
It can be 5,6 and 7 etc., determined according to calculating, the present invention does not limit the quantity of lath 2.Adjacent two lath 2
The distance between according to calculate and detailing requiments determine, the distance between adjacent two lath 2 can be equal, i.e., lath 2 is uniformly set
It sets, so that every lath 2 is more uniformly stressed, the stability and load-bearing capacity on basis can be improved.Beam-board group of same model
In box-like basis, the size of lath 2 is consistent, and interchangeability is good, and versatility is stronger.
The crossbeam frame includes multiple tiers of beams, and each tiers of beams includes the more crossbeams being parallel to each other 3, and crossbeam 3 is
Reinforced beam, cross section are in rectangle, and whole is in cuboid.The quantity of the crossbeam 3 of each tiers of beams can be 2,3
Or more, it is preferred that each tiers of beams includes 2 crossbeams 3.3 length of crossbeam of each tiers of beams can be consistent, but in order to improve
The stability on the box-like basis of beam-board group of the present invention, 3 length of crossbeam of tiers of beams is sequentially reduced from bottom to up, so that entire crossbeam
Frame is that upper end is small, and the big pyramid in lower end, after being embedded to underground, stability is stronger, is able to bear bigger uplift load,
And since 3 length of the crossbeam on upper layer is shorter, is conducive to save material, be readily transported.The box-like basis of beam-board group of same model
In, the size positioned at the crossbeam 3 of the identical number of plies is consistent, and 3 size of crossbeam of such as tiers of beams of multiple concrete foundation top layers is complete
Portion is consistent, in this way, the crossbeam on the basis of different beam-board groups is box-like can be interchanged, component versatility is stronger, is conducive to quick group
Dress, is easy to implement mass production.The number of plies of tiers of beams can be according to requiring to be configured, such as 5 layers, 6 layers, 7 layers, the present invention
With no restriction.
The crossbeam 3 of adjacent two tiers of beams is mutually perpendicular to and is detachably connected, and the crossbeam 3 of bottom tiers of beams is perpendicular to lath
It 2 and is detachably connected with lath 2, column 1 is connect with the tiers of beams of the top.It specifically, can be in the upper of lath 2 and crossbeam 3
Cylindrical or cuboid positioning is arranged in the lower surface of crossbeam 3 and column 1 in the jack of the round perhaps rectangle of surface setting
Column, using positioning column with jack grafting, it can be achieved that crossbeam 3 and lath 2, crossbeam 3 and crossbeam 3 and column 1 and crossbeam 3 it is quick
Assembling enhances the stability that basis is set in entire assembly to improve bonding strength, and the crossbeam 3 of bottom tiers of beams passes through bolt
It is connected with lath 2, the crossbeam 3 of adjacent two tiers of beams is connected by bolt；The column 1 includes vertical section and horizontal segment, vertically
Section and the molding of horizontal segment formed by integrally casting, the vertical section and horizontal segment are in inverted T-shaped, and vertical section passes through pre-embedded bolt and top iron
Tower tower leg is connected, and horizontal segment is connected by bolt with lower beam.It is bolted securely, and operates more convenient.
Bottom support layer is set as multiple laths 2, and the volume and weight of lath 2 is small, is readily transported and constructs.The present invention is whole
Body is in stepped frame structure, and overall weight is smaller, each component detachable transportation, very convenient, and when construction also can be quick
Assembling guarantees construction efficiency.In addition, the box-like basis of beam-board group of the invention is that Path of Force Transfer is clear, each member stress is reasonable.
Each component is the solid of rule, production easy to process, while being easy to in-site installation, and each structural elements versatility is high.It can root
According to the different buried depth for the number of plies optimized integration for adjusting tiers of beams, to meet the requirement for bearing capacity of different basic uplift loads.
The construction method on the box-like basis of above-mentioned beam-board group suitable for work transmission line, comprising the following steps:
A, excavation of foundation pit.Before foundation excavation, drainage measure around building site flood control and foundation pit should be first carried out；When excavation of foundation pit,
Should be preferably continuous to excavate by construction drawing requirement slope, basic assembling should be carried out after the completion of excavation as early as possible, when reducing process interval
Between, shorten foundation pit exposure duration；It should be noted that excavation slope is stablized when excavation, can suitably slow down grade of side slope or setting branch when necessary
Support.
B, Foundation Pit bottom is grasped and is put down, foundation pit bottom answers multiple spot behaviour flat, keeps hole bottom substantially smooth, then spreads coarse sand or fine crushing
Masonry is bed course 4, then multiple spot behaviour puts down, and keeps full hole hole bottom smooth, basis is smoothly placed in foundation pit when being conducive to assembly, to guarantor
The box-like basic installation quality of card beam-board group plays an important role.The hardness of coarse sand or fine stone is much larger than soil, basic after compression
It will not deform, can steadily support concrete foundation, can prevent concrete foundation from tilting.
C, each lath 2 of bottom support layer is hung to Foundation Pit bottom using lifting appliance and put in place, recycled
Equipment is hung the crossbeam 3 of each layer tiers of beams is successively hung to foundation pit and is assembled in place.After lath 2 is hung in foundation pit, set lath 2
Enter in bed course 4, the upper surface of bed course 4 is flushed with the upper surface of lath 2.Connection through-hole has been preset on lath 2 and crossbeam 3, has been
Convenient for assembling, when to lath 2 and the lifting of crossbeam 3, bolt can be put into lath 2 and the preset connection of lower layer's crossbeam 3 is logical
Kong Zhong, it is subsequent lifting upper layer crossbeam 3 when, will be transferred after the connection through-hole alignment bolt on upper layer crossbeam 3, then again by nut
It is installed on bolt, lath 2 and crossbeam 3 is tensed.In this process, it is carried out after every assembling for completing one layer of tiers of beams primary
The gap of foundation pit is filled up in foundation pit backfill, guarantee, and compacting is primary when the every backfill 250mm of backfill is to 300mm thickness, guarantee concrete
The inbuilt stabilization in basis.
D, column 1 is lifted to the top of crossbeam frame and is assembled in place, foundation pit is filled and led up and tamped, as shown in Figure 3.
