Description
Technical field
The invention belongs to technical field of bridge construction, it is related to a kind of cast-in-place bracket of assembly concrete to connect wall node.
Background technology
Building higher high up in the air, because separation is higher from the ground, sets side using molded armored concrete facade more
Bracket forms construction operation platform, part building of encorbelmenting of being constructed on this platform bracket.
Because bracket bearing capacity is big, economical rationality, the large structure such as current Bridge High-pier top surface continuous beam 0# blocks is encorbelmented portion
Divide and constructed using the method.
Because of bracket, stress clearly, is at present difficult have optimization space again in itself, only the connecting node of bracket and wall, because receiving
Power is complicated, and current common practice is difficult to accomplish that optimization is processed, and there is the excessive waste of materials of safety stock more, or because of construction technology
It is larger Deng limitation potential safety hazard.
Now widely used node mode has two kinds：One kind is that one kind is to utilize shaped steel using crab-bolt class power transmission node
Weld or be hinged with support Deng built-in fitting in component.Above two technical scheme is only merely using pre-buried steel construction structure in concrete
Part node, is allowed to bear shearing, pressure or pulling force that bracket is transmitted etc., it is impossible to give full play to various material stress advantages, component
Stress is complicated, so that the complicated heaviness of structure, and live labor content is big, and precision and quality are difficult to ensure that.
The content of the invention
Connect wall node it is an object of the invention to provide a kind of cast-in-place bracket of assembly concrete, it is existing using assembling type node
Field is connected by the way of welding is exempted from embedded structure thing wall, makes full use of compressive property, the steel-concrete combined structure of concrete
Shear behavior, reinforcing pull rod（Screw rod, bolt etc.）Tensile property, need not be cut off during node installation wall or bridge pier reinforcing bar and
Cut its formwork for placing, have the advantages that stress clearly, materials province, steady quality, security reliability be strong, constructing operation is convenient.
The purpose of the present invention is achieved through the following technical solutions：
A kind of cast-in-place bracket of assembly concrete connects wall node, including shelf bracket, upper even wall node, lower even wall node, reinforcing bar
Concrete wall, wherein：
The upper even mast node is used to bear horizontal pull and vertical shear, is made up of pull bar and upper shear connector, pull bar it is pre-buried or
Reinforced concrete wall is communicated through, the upper force-transmitting seat of shelf bracket draws by the way that pull bar and reinforced concrete wall are closely connected for bearing level
Power, upper shear connector is embedded in reinforced concrete wall body and is used to undertake vertically cut at node with the bottom closing contact of upper force-transmitting seat
Power；
The lower even wall node is used to bear horizontal pressure force and vertical shear, is made up of anchoring piece and lower shear connector, anchoring piece anchor
Gu in reinforced concrete wall body, the lower force-transmitting seat of shelf bracket is connected to bear horizontal thrust by anchoring piece and concrete wall, under
Shear connector is embedded in reinforced concrete wall body and is used to undertake vertical shear at node with the bottom closing contact of lower force-transmitting seat.
The invention has the advantages that：
1st, in addition to cast-in-place concrete, all components are factory process, and element structure is simple, and low cost, high precision, quality have guarantor
Card；
2nd, various primary structure member distincts, stress clearly, is convenient for force analysis optimization design；
3rd, live people's power cooperation crane, it is only necessary to which the small instruments and tools such as hand hammer, spanner can complete prefabricated member in-site installation, without
Site Welding, quick and easy for installation, node installation of embedded parts need not cut off existing bridge pier（Wall）Deng works stress cage bar and
Template；
4th, construction finishes component and removes simple, and wall is without exposed metal accessory, and concrete structure outward appearance is clean and tidy；
When load-bearing support body the 5th, being set suitable for reinforced concrete structure side, used as even wall stress node.
6th, upper node and lower node two types node use assembled, and after each joints are decomposed, each part holds
Load different loads, mechanical model is clear, is easy to be checked and optimization design by calculating and experiment.
7th, the present invention uses assembling type node, upper lower node to undertake vertical shear using shearing resistance built-in fitting, and upper node is adopted
Horizontal pull is born with pull bar, lower node bears horizontal pressure force using Pressure Block by wall, take full advantage of various material stress
Can advantage：Concrete structure resistance to compression, high-strength steel bar tension, steel-concrete combined structure shearing resistance, at utmost save material usage.
8th, the present invention, using assembling type node, makes at node several component respectively by assembled according to joints condition
Each part of node undertakes respectively, and part stress clearly, easily establishes mathematical analysis model and accurate to its by load test
Analysis and checking, ensure that quality avoids live manufacturing deficiency using batch production processing.
9th, the assembling type node has universal promotional value in terms of economy, security, operability etc..
