Description
The utility model relates to a kind of open web type hollow square that is used for port and pier.
In port works dock wall structure types, the hollow square harbour is one of the most frequently used structural shape.Empty van formula hollow square generally is made up of base plate, antetheca, rear wall, sidewall and several parts of central longitudinal cross wall, generally by crane ship lifting and installation, shows as Fig. 1.The hollow square dock structure is fast because of speed of application, structural integrity good, good endurance, the compliance of harbour load is widely adopted by force.The use history of hollow square dock structure has half a century approximately.Because former water transportation boats and ships are little, the height of dock wall is little, add the restriction of the lifting erection equipment ability that is subjected at that time, thereby hollow square dock wall generic hierarchical is built into, even not stratified hollow square is arranged, this hollow square also is the dwarf-type structure.Since nearly 10 years, along with the increase of world's transport by sea car loading, ships that transport also progressively maximizes, the also more and more large-scale change of dock structure, and the maximum bulkhead wall height of hollow square harbour has surpassed 25m.So tall and big bulkhead wall requires big hollow square certainly, and be the supporting use of hollow square and relieving slab (being used for reducing the soil pressure that the soil body produces behind the wall) basically, the dock structure of the supporting relieving slab of this large hollow square has become a kind of maturation pattern of effectively arranging in pairs or groups in the large pier engineering.Just because of the large hollow square is by small-sized development, thereby some usual practices of small-sized hollow square structure also continue into the present basically.By analysis, the main effect of hollow square is to keep off soil and the formation bulkhead wall, the large hollow square also need support the relieving slab on its top, thereby requisite part is an antetheca in the hollow square structure, base plate is used for adjusting bedding stress and guarantees that the anti-work of inclining of filler full entry also should keep in the square, also need there be relieving slab " support " large hollow square upper end, other members such as rear wall, sidewall and in length and breadth partition wall do not belong to indispensable part, thereby can simplify even cancel.Traditional hollow square also has square partition wall part " on an empty stomach ", but on an empty stomach rate is little, and never occurs with sidewall and wall on an empty stomach even the hollow square of cancellation (be that entity is real abdomen on plate or the wall plane, have on the plane to be emptied than large tracts of land to be called on an empty stomach).Real abdomen formula hollow square is compared with the open web type hollow square, and its tangible weak point is arranged:
1, real abdomen formula hollow square Reinforced Concrete Materials consumption is big;
2, because real fu jie structure weight is big, so under the certain situation of appearance and size, lifting, transportation and installation are established
The requirement height that is equipped with is particularly to the requirement height of the crane capacity of lifting appliance; Or it is certain at crane capacity
Situation under, real fu jie structure appearance and size is unfit to do greatly, cause prefabricated in the harbour engineering construction, the transportation and
The hollow square number of packages of installing increases;
3, above 2 all can cause the investment of harbour engineering to increase and the construction period prolongation.
The purpose of this utility model is to provide a kind of material saving, saving working hour and the open web type hollow square that is used for port and pier easy for installation.
In order to achieve the above object, a kind of open web type hollow square that is used for port and pier of the present utility model, form by base plate and the antetheca on base plate, rear wall, sidewall, cross wall, mediastinum wall, connect two sidewalls and the cross wall between two sidewalls between antetheca and the rear wall, mediastinum wall between antetheca and rear wall is connected with cross wall with two sidewalls, it is characterized in that: the centre position of two side and cross wall is provided with opening, and this aperture area accounts for the 15-40% of whole wall wall; The mediastinum wall is no less than 2 meters from the height of base plate; Rear wall is divided into rear wall and inferoposterior wall, and the height of last rear wall and inferoposterior wall is no less than 3 meters and 2 meters respectively.
The utility model has following advantage than prior art:
1, saves steel concrete: 15-25%
Reduce hollow square number of components: 15-25%
The square individual works duration shortens: 15-25%
Save square individual works investment: 15-25%
2, transportation and easy for installation.
The structural representation of Fig. 1, real abdomen formula hollow square,
Fig. 2, be the structural representation of the concrete a kind of embodiment of the utility model,
Fig. 3, be the application schematic diagram of the concrete a kind of embodiment of the utility model.
Of the present utility model a kind of open web type hollow square that is used for port and pier as shown in Figure 2, form by base plate 1 and the antetheca on base plate 12, rear wall 3, sidewall 4, cross wall 5, mediastinum wall 6, connect two sidewalls 4 and the cross wall between two sidewalls 45 between antetheca 2 and the rear wall 3, mediastinum wall 6 between antetheca 2 and rear wall 3 is connected with cross wall 5 with two sidewalls 4, the centre position of two side 4 and cross wall 5 is provided with opening, and this aperture area accounts for 35% of whole wall wall; Mediastinum wall 6 is 3 meters from the height of base plate; Rear wall 3 is divided into rear wall 31 and inferoposterior wall 32, and the height of last rear wall 31 and inferoposterior wall 32 is respectively 3 meters and 2 meters.
Why can real abdomen formula hollow square be improved to open web type? cardinal principle is to require relevant with the inner forces calculation pattern and the structure of each ingredient of hollow square.Inner forces calculation and the structure of analyzing each member below in conjunction with Fig. 1 require to illustrate principle on an empty stomach.
Antetheca (2): antetheca (2) is to be used for keeping off the necessary member that soil forms bulkhead wall, therefore can not be on an empty stomach.The inner forces calculation pattern of antetheca (2) and base plate (1) and cross wall (5) and sidewall (4) are directly related.The antetheca of the above 1.5L of base plate (L is a sidewall tabula spacing) is fixed by three limits, the single orifice plate of freely-supported calculates on one side, 1.5L above antetheca inner forces calculation is calculated by two ends fixing continuous slab or single span plate, therefore, for antetheca (2), sidewall (4) and cross wall (5) play supporting and consolidation, and be therefore essential.But essential being not equal to can not be empty, and keeping suitable coupling part does not influence its fixed or supporting role to antetheca (2), does not change the pattern and the span of antetheca inner forces calculation, so sidewall (4) and cross wall (5) can empty stomaches.
Sidewall (4): sidewall (4) is not subjected to the effect of horizontal force, it act as fixed front wall and base plate and bear the lifting hole(eyelet) vertical, therefore, except that be used for fixing antetheca, base plate and bear the peripheral part of lifting hole(eyelet) active force essential, mid portion can be on an empty stomach from structure and force request.
Base plate (1): the cell of base plate should calculate by the fixing single orifice plate in four limits, the suspending wall part of base plate is pressed cantilever and is calculated, therefore, for base plate, antetheca, rear wall, partition wall, sidewall are all essential in length and breadth, otherwise can influence the inner forces calculation pattern or the internal force value of base plate, but base plate required only for playing the 2-3m of coupling part of fixation, remainder can be excavated.
Rear wall (3): rear wall is not subjected to horizontal force action equally, and the 2-3m of a need lower end is used for fixing base plate and upper end 2-3m is used for supporting relieving slab, so the rear wall midfield can cancel all.
Cross wall (5): cross wall is not subjected to horizontal force action not to be subjected to vertical force yet, only because need be used for fixing antetheca, base plate and supporting rear wall upper part, from textural essential.As a same reason, the 2-3m wall of a need coupling part fixes antetheca, base plate and supporting rear wall upper end and gets final product, and all the other can be excavated.
Mediastinum wall (6): the mediastinum wall is not subjected to horizontal force and vertical force, is because it is a bearing that is used for fixing base plate yet, thereby essential, but the 2-3m height that also only need link to each other with base plate, remainder can be excavated.
From top analysis as can be seen, the Force Calculation pattern of each member of open web type hollow square does not change because of the empty stomach of some member, the globality of square is not affected, and satisfies constructional requirement simultaneously yet, and what " on an empty stomach " sky fell is unnecessary part.
The example that Fig. 3 lifted is the open web type hollow square harbour profile of a band relieving slab.As can be seen from the figure, the hollow square dock structure is made up of riprap foundation (10), hollow square, relieving slab (8), cast-in-place breastwork four parts such as (9).Hollow square wherein is the core in the dock structure, also is the member that accounts for investment and duration share maximum, because the employing of technology on an empty stomach will obviously reduce the investment and the duration of harbour engineering.In general, (it was not necessarily economical to use the empty stomach hollow square in the middle-size and small-size harbour among hollow square was suitable for being applied to the large pier structure on an empty stomach, because the counterfort structure applications can more be saved in middle-size and small-size harbour), and should possess the lifting appliance that big crane capacity (being generally 500t) is arranged.In addition, on an empty stomach the well way of filtering of hollow square harbour is similar to the buttressed quay wall way, and a hollow square of the termination of the seal head section of harbour should be made outside sidewall real abdomen type to satisfy the requirement of sealing filler.
As can be seen, open web type hollow square harbour can reach and the same result of use of real abdomen formula hollow square from profile, but can save material significantly and save the duration.
