Description

Energy-dissipating and shock-absorbing dense rib composite wallboard and its manufacturing method

technical field

The invention is applicable to the dense rib structure system, and is a new type of energy-dissipating wall. It is suitable for seismic fortification areas or building structures with high requirements for earthquake fortification.

Background technique

In recent years, earthquakes have occurred frequently all over the world, which has brought huge disasters to human production and life. Seriously restricted the progress of human civilization. In particular, China is a country with a high incidence of earthquakes, coupled with its large population, densely populated houses, and low levels of earthquake resistance of houses, resulting in huge casualties and economic losses every time an earthquake strikes. In addition, with the development of new rural construction, an economical, earthquake-resistant, and fast-construction structural system is required to be suitable for the current large-scale urban and rural construction.

Therefore, the proposal of the structure system of the densely ribbed composite wall has successfully solved such problems. The patent of CN200610001006.6 discloses a new type of structure named "Micro-ribbed structure system and its connection construction method". The ribbed structural system of the invention includes a ribbed composite wall panel, an invisible frame and a floor slab. The dense rib composite wall panel is a grid-shaped building component composed of rib beams, rib columns and lightweight filled blocks made of reinforced concrete. Divided and formed by embedding lightweight material filling blocks in the grid; the densely ribbed composite wall panel also includes beard tendons protruding from the rib beam columns, and the beard tendons are four straight ribs extending from each rib beam column. When connecting, make a hook at the end to hook the longitudinal rib of the connecting column; or the beard tendon is two U-shaped closed rings protruding from each rib beam column, and the longitudinal rib is inserted into it when connecting. The invisible frame is composed of outer frame columns, connecting columns and concealed beams nested on the periphery of densely ribbed composite wall panels. Ordinary reinforced concrete beams and columns, shaped steel reinforced concrete beams and columns or steel structure beams and columns can be used. Filling blocks are processed from lightweight materials with a certain strength and small bulk density and elastic modulus. The floor is in the form of cast-in-place concrete, cast-in-place or prefabricated densely ribbed composite floor, prestressed laminated floor or special-shaped prestressed hollow floor. The structural system has the characteristics of local materials, good seismic performance, short construction period, good energy-saving effect, low engineering cost, and is suitable for multi-storey and middle-rise residential buildings.

But still there is the defective of following several aspects in this kind wallboard:

(1) In the traditional densely ribbed composite wall structure system, the lightweight materials used for the filling blocks of the wall include plant fiber concrete, EPS concrete, foamed concrete, etc. Filling blocks and rib beams and rib columns are integrally poured and formed. Under the action of earthquake, the filled block produces plastic deformation, which causes hysteretic energy consumption to consume seismic energy. However, because the filling blocks are made of brittle materials and have low strength, their energy dissipation capacity is limited.

(2) In the conceptual design of the traditional densely ribbed composite wall structure system, there are three lines of defense. The plastic energy consumption of the deformation and cracking of filling blocks is the first line of defense of this structural system. Due to the insufficient damping of the filled blocks, under frequent earthquakes, the filled blocks first undergo irreversible plastic failure, and the ability to consume earthquake energy is very limited. It cannot meet the seismic fortification requirements that small earthquakes are not damaged.

(3) Due to the design characteristics of the densely ribbed composite wall, the filling blocks will be damaged under frequent earthquakes, and new blocks need to be replaced. As a result, in earthquake-prone areas, the replacement and maintenance of filling blocks is very troublesome.

Contents of the invention

The technical problem to be solved by the present invention is to solve the problems of cracking of densely ribbed filling blocks under small earthquakes and frequent replacement and maintenance of filling blocks, so that the seismic performance of densely ribbed walls is enhanced.

In the process of studying the seismic performance of the densely ribbed composite wall system. The applicant found that the main factors affecting the response of the building structure under earthquake action are the mass, stiffness, damping, etc. of the structure, among which the damping is the most influential factor. Aiming at the deficiencies of the existing technology, starting from improving the damping of the structural system, by changing the connection mode between the filling blocks and rib beams and rib columns, the energy dissipation capacity of the dense rib structure is enhanced and the seismic response of the structural system is weakened.

The technical scheme that the present invention solves its technical problem is:

Energy-dissipating and shock-absorbing dense rib composite wall panels, the composite wall panels include: filling blocks, reinforced concrete rib beams and reinforced concrete rib columns; filling blocks are located in the reinforced concrete grid formed by reinforced concrete rib beams and reinforced concrete rib columns middle.

The top and bottom surfaces of the filling block and the reinforced concrete rib beams in the reinforced concrete grid are connected by concave-convex grooves and grooves, with a layer of glue-mixed graphite in between.

Viscoelastic materials are placed between the two sides of the filled blocks and the reinforced concrete rib columns.

Protrusions are provided on the top and bottom surfaces of the filling blocks, and grooves are provided on the reinforced concrete rib beams in the reinforced concrete grid. The cross-sections of the protrusions and grooves are dovetail or rectangular.

When the sections of the protrusions on the top and bottom surfaces of the filled blocks and the grooves on the reinforced concrete rib beams in the reinforced concrete grid are dovetail-shaped, the dovetail angle is 40-50 degrees.

The top and bottom surfaces of the first reinforced concrete middle rib beam and the second reinforced concrete middle rib beam are grooved on both sides, and the bottom surface of the reinforced concrete top rib beam and the top surface of the reinforced concrete bottom rib beam are grooved on one side. The slot size and form are the same.

When slotting on both sides, the ratio of the cross-sectional area of the slotted part to the cross-sectional area of the rib beam in reinforced concrete is 0.117 to 0.200.

When grooved on one side, the ratio of the cross-sectional area of the grooved part to the cross-sectional area of the reinforced concrete top rib beam or reinforced concrete bottom rib beam is 0.067 to 0.125.

The thickness of the viscoelastic material placed between the filling block and the reinforced concrete rib column is 2-6 cm.

The coating thickness of a layer of glue mixed with graphite is 1-4mm.

The materials used in the filling block are lightweight concrete including: foamed concrete, plant fiber concrete, ceramsite concrete or ecological EPS concrete; the materials used in the viscoelastic material include: isoprene rubber or butadiene rubber .

A method for manufacturing an energy-dissipating and shock-absorbing densely ribbed composite wallboard, the manufacturing method comprising the following steps:

Step 1, making the reinforced concrete grid described in claim 1, the form of the reinforced concrete grid is 3×3, 3×4, 3×6.

Bind the longitudinal bars and stirrups of the reinforced concrete rib beams and reinforced concrete rib columns, and then make the reinforced concrete grid formwork of the reinforced concrete fine-rib composite wall panel according to the form of the reinforced concrete grid and groove; after the formwork is completed, pour the concrete Conservation molding.

Step 2, place the poured reinforced concrete grid in a standard environment for curing, remove the formwork at the groove after the initial setting of the concrete, mix the graphite powder with glue and evenly spread it on the lower surface of the reinforced concrete rib beam , The upper and lower surfaces of the first and second reinforced concrete rib beams, and the upper surface of the reinforced concrete bottom rib beam, form a graphite lubricating layer, place it until the glue is dry, and then apply it evenly again. The thickness of the graphite mixed with glue is 1~ 4mm.

Step 3, on the inner surface of the first and fourth reinforced concrete rib columns and the two side surfaces of the second and third reinforced concrete rib columns in the reinforced concrete grid, arrange a viscoelastic material cushion with a thickness of 2-6cm .

Step 4: Brush engine oil around the inner side of the reinforced concrete grid formed above, arrange formwork, pour filling blocks, and maintain the shape.

The invention changes the connection mode between the filling block and the reinforced concrete rib beam, and changes the traditional direct pouring fixed connection into a dovetail groove connection. And apply graphite powder mixed with ordinary glue on the connection seam to reduce the friction coefficient. In order to facilitate construction and installation and avoid stress concentration, the concave-convex groove connecting the rib beam and the filling block can be changed into a right-angle form. The specific slot size range is the same as the dovetail slot connection method, and ordinary glue is mixed with graphite powder at the connection joint. This kind of connection is similar to the directional support in structural form, which can bear vertical load and bending moment, but there is no horizontal constraint. Due to the anti-friction effect of graphite powder, the filling block can slide left and right along the groove of the reinforced concrete rib beam under earthquake action, without affecting the vertical bearing capacity of the structural system. 2. Change the connection method between the filling block and the rib column. Cast-in-place fixed connection is adopted in the traditional dense rib structure, but in the present invention, a certain gap is left between the filling block and the rib column. The gap width is 2cm-6cm. In order to consume the kinetic energy generated by the movement of the filling blocks, a viscoelastic material cushion (such as butadiene rubber or isoprene rubber, etc.) is arranged between the filling blocks and the reinforced concrete rib column, and the seismic energy is consumed through the deformation of the cushion. The entire structure converts the seismic energy into the kinetic energy of the filled blocks, and then converts the kinetic energy into the deformation energy of the cushion rubber, and finally dissipates the deformation energy through the viscoelastic material cushion, and at the same time, frictional energy is also dissipated between the blocks and the reinforced concrete rib beams. .

The beneficial effect of the present invention compared with the existing densely ribbed composite wall:

(1) Due to the adoption of this connection method, under the horizontal dynamic load imposed on the structure by the earthquake, the filling blocks can move horizontally in the middle of the grid. Part of the energy transmitted by the earthquake to the structure is consumed by the horizontal movement of the filling blocks and the friction between the filling blocks and the rib beams.

(2) Since the filling blocks are not directly connected to the reinforced concrete rib columns, viscoelastic materials are placed in the gaps. As the filling block moves horizontally, the viscoelastic material on one side will be squeezed, causing it to deform. After reaching a certain level, the deformation will recover and react on the filling block. Make it move in the opposite direction and squeeze the viscoelastic material on the other side. Such a reciprocating cycle gradually consumes seismic energy.

(3) This repeated cycle will be broken only when the seismic action is relatively large or lasts for a relatively long time. The infill blocks begin to crack, fail plastically, and continue to absorb excess seismic energy. The structural system began to enter the originally expected three-stage destruction energy consumption. The invention is equivalent to adding the zero-stage energy consumption process to the ribbed composite wall system, that is, the filling blocks move and the viscoelastic materials on both sides are squeezed until the filling blocks begin to crack.

(4) The densely ribbed system under the present invention simultaneously consumes energy through sliding friction, viscoelastic material deformation and filling block plastic deformation under large earthquakes, while the existing densely ribbed walls can only consume energy through plastic deformation.

In a word, the present invention can continuously convert and dissipate the energy sent by the earthquake in the dense rib structure between the kinetic energy of the filling block, the heat energy generated by the friction when the filling block slides, and the deformation energy of the viscoelastic material, and finally achieve the goal of filling the block No damage occurs under small or even moderate earthquakes. It plays the role of delaying the failure process of the entire structural system and making the ribbed composite wall system withstand the test of greater earthquake action.
