Description
Technical field
The present invention relates to the supporting and protection structure part of building underground construction deep foundation ditch.
Background technology
Need set up support member in the underground construction deep foundation pit construction process between deep foundation pit fender post, common this support member adopts cast-in-situ steel reinforced concrete and callable steel pipe or two kinds of forms of shaped steel.Though the cast-in-situ steel reinforced concrete support member has applying flexible, safe and reliable advantage, its operation is many, speed of application is slow, as provisional member its consume that material is many, cost is high, from great, utilization rate is low, demolition blasting influences surrounding enviroment again; Though steel pipe or shaped steel support member can reuse, it installs little, the difficulty of cutting the earth of spacing between complicated, the support member, in addition, because of disposable have high input and turnover rate with turn of the market, its actual amortization cost is also higher.
The reinforced concrete pipe pile that adopts batch production production is as the pressurized support bar, the supporting way that props up piece in conjunction with power transmission conversion connector, prestressing force drag-line and cast-in-situ steel reinforced concrete node has absorbed the advantage of above-mentioned two kinds of supporting forms, overcome the shortcoming of traditional support member, and this kind supporting way is not seen application and report.
Summary of the invention
The present invention is for solution deep foundation pit fender post support member cost height at present commonly used and cast-in-situ steel reinforced concrete support member consumption material is big and explosion influences problem of environment, the support member of a kind of deep foundation pit fender post of this novel practical is provided for this reason, this support member can reuse, it supports to compare with the conventional steel reinforced concrete and can reduce cost more than 50%, and the shoveling space is big, speed of application is fast, system easy to control the quality.
For addressing the above problem, the technical solution used in the present invention is to be provided with alternate in length and breadth node to prop up part, described node props up and is connected with pole between part, its special character is that described pole is the reinforced concrete hollow pipe, and described node props up part and is made of with the connector combination that can be connected with described reinforced concrete hollow pipe reinforced concrete block; Described connector is by constituting with connect block plate, the adapter steel plate that can be connected with described reinforced concrete hollow pipe and the described lengths of steel pipes welding that connects block plate and take between the steel plate of described reinforced concrete block connection; Described adapter steel plate periphery offers bolt hole; Described reinforced concrete hollow pipe and the end face that described connector connects are associated with this steel plate periphery of steel plate and offer hole with the corresponding band silk mouth of the bolt hole of described adapter steel plate periphery, and the steel plate of described adapter steel plate and described concrete hollow pipe end face mutually combines through the hole that bolt penetrates described bolt hole and band silk mouth described reinforced concrete hollow pipe is connected with described connector; Be associated with vertical pillar below the described reinforced concrete block;
Described node prop up part vertically alternate have two at least, laterally alternate has two, longitudinal and transverse four adjacent described nodes prop up part and are in quadrangle drift angle place, described node prop up in the described reinforced concrete block of part by described quadrangle to the angular direction wear and be embedded with the pipe of reeving, described quadrangle props up the steel concrete interblock Zhang Lianyou drag-line of part to the node of angular direction, and this stay cable end passes the described pipe tensioning of reeving and is fixed in the described pipe outer end of reeving.
Described drag-line is preferably steel strand.
Prop up the off-centre that connects the support of reinforced concrete hollow pipe between part in order to reduce described node, weldering has the triangle stiffener on the steel plate that should be connected at lengths of steel pipes and this lengths of steel pipes two ends of described connector.
The present invention should offer bolt hole described the connecing of the vertical both sides of described reinforced concrete block connection on the block plate, the vertical both sides of described reinforced concrete block are joined described connect to stride between the block plate to wear be fixed with the break-through bolt, described break-through bolt passes described bolt hole and described reinforced concrete block, break-through bolt two ends are through fixed by nut, and node props up the issuable pulling force in part place when preventing to support whole unstability.
Under the excessive relatively situation of abutment pressure, the reinforced concrete hollow pipe that described node can be propped up between the part makes to be many binding combination into by single, to meet the compressive strength requirement.
The block plate that connects of described connector is preferably rectangular steel plates, is preferably circular steel plate by the pipe steel plate, and the steel plate of reinforced concrete hollow pipe end face is the ring-type steel plate.Weldering connects described lengths of steel pipes between the adapter steel plate that connects the block plate and the other end of described connector one end, have enough distances and space thus, be convenient to the installation and removal of bolt, nut, make being connected and convenient disassembly of described reinforced concrete hollow pipe and described connector.
Reinforced concrete hollow pipe of the present invention is the reinforced concrete pipe pile that existing batch production is produced, i.e. " pretensioning prestressed reinforced concrete pile tube ".
The present invention adopts the prestress thin wall pile tube of widely applying in construction work as support bar, and this tubular pile concrete intensity reaches C80, and compressive strength is very high, and good rigidly, and weight is lighter relatively, and is easy for installation.Pile tube is made in batches in factory, and quality is good, and price is low, and therefore the recycling highly versatile is compared cost with the support of conventional steel reinforced concrete and reduced greatly.Its effect of steel structure connecting member is that the reinforced concrete block that props up part with node that makes that the reinforced concrete hollow pipe can be convenient and reliable connects, the off-centre that simultaneously can regulate reinforced concrete hollow pipe depression bar, make actual loading meet calculation assumption, the block plate that connects of connector can also be as the template of cast-in-situ steel reinforced concrete piece.And the cast-in-situ steel reinforced concrete piece not only power transmission is reliable, and compliance is strong, adopts fast hardening concrete accelerating construction progress and provide condition for the stretch-draw of prestressing force steel hinge line greatly.The prestressing force steel hinge line can bonding to the monolithic stability that supports, and can reuse the work efficiency height.
