Description
Technical field
The utility model is related to a kind of prefabricated assembled arches, belong to the building structure field in civil engineering.
Background technology
Arch is a kind of important structure type, is widely used in the buildings such as bridge, roof system, tunnel.Come from amechanical angle
It sees, arch is the curved bar that horizontal thrust is generated under a kind of vertical uniform load q in own layer.With compared with the beam of span,
Since there are horizontal thrusts, encircle each section based on being pressurized, moment of flexure and shearing very little, therefore, compression strength height but tensile strength
Low fragile material is very suitable for building arch, such as stone material, building block, concrete.Have benefited from effective performance of material mechanical performance,
Arch structure saves material, and the rigidity of structure is larger, can effectively increase the span of structure.
Currently, for the larger arch of large span, from the point of view of form of construction work, masonry arch, cast-in-place arch and Prefabricated arch can be divided into
Three kinds.For masonry arch and cast-in-place arch, need to set up a large amount of holder and formwork, heavy workload, construction period at the construction field (site)
It is long, and influenced by field condition, it is also very big to surrounding environment influence.In contrast, Prefabricated arch need not be taken at the construction field (site)
If holder, there are the advantages such as construction efficiency height, wet-less operation, have a good application prospect.But according to the pre- of existing Prefabricated arch
System and form of construction work, first will be in factory by using mold, and the arch of prefabricated different curvature, there is still a need for set up holder to this process
And formwork, the size of required template is not also small, and installation requirement is high.It is prefabricated difficult when the span of arch is larger.In addition,
Transport in Prefabricated arch and hoisting process are the horizontal force at support pedestal, prevent from plowing and split, and need that interim branch is arranged in lower part
Support or pull rod, it is desirable that high, installation difficulty is big.Thus, in Practical Project, the span of Prefabricated arch is very limited.Therefore, exploitation is a kind of
Novel prefabricated assembled arch, becoming reduces the prefabricated difficulty of this structure, the key of installation difficulty and expenditure of construction.
Invention content
The purpose of this utility model is to provide a kind of prefabricated assembled arch, have from heavy and light, prefabricated simple, assembly is easy and
The features such as construction cost is low.
The technical solution of the utility model is：A kind of prefabricated assembled arch, it is characterised in that：The concrete of longitudinal arrangement
Native hollow block (1) is connected by the fabric reinforced cement based material layer (2) for pouring at an upper portion thereof；It is characterized in that：It is adjacent
The angle of angle (3) between two precast concrete hollow block (1) sides is come true according to the shape and curvature of design arch
It is fixed；The side setting groove (4) of precast concrete hollow block (1).It is characterized in that：When lifting, fabric reinforced cement sill
Layer (2) cracks in the seam crossing of precast concrete hollow block (1), and angle (3) is closed, forming curves arch, and in groove (4)
Pour into binding material (5).It is characterized in that：Precast concrete hollow block (1) includes：Plain concrete hollow block and armored concrete
Hollow block.It is characterized in that：Fabric reinforced cement based material layer (2) includes：Fabric enhances the cement matrix bed of material and steel wire
The net enhancing cement matrix bed of material.
Compared with existing prefabricated assembled arch, the utility model has the advantage of：
(1) from heavy and light.The agent structure of prefabricated assembled arch is made of precast concrete hollow block, and dead weight is small.In addition, even
Connect precast concrete hollow block is one layer thin of fabric reinforced cement based material layer, and material utilization amount is few.Therefore, it is of the invention from
Heavy and light.
(2) prefabricated simple.The structural unit of prefabricated assembled arch be precast concrete hollow block, size is smaller, shape compared with
To be regular, and by reasonably designing, a few class standard prefabricated sections can be become.Therefore, in prefabrication process, small ruler may be used
Very little gang form is individually prefabricated, then precast concrete hollow block is arranged along longitudinal direction, and one layer of fabric enhancing is poured on top
The cement matrix bed of material, you can complete prefabricated.In this prefabrication process, without large-scale template, without setting up holder, it is prefabricated very
Simply.
(3) assembly is easy.In transportational process, the precast concrete hollow block of longitudinal arrangement is in clinostatism state, will not
Horizontal thrust is generated, also just there is no thus caused cracking risks, because without temporary support is arranged.In hoisting process,
Under Gravitative Loads, the fabric reinforced cement based material layer between two neighboring precast concrete hollow block is by curved cracking, due to knitting
The presence of object enhancement layer will not scatter between prefabricated section, but produce relative rotation, and the angle between side is closed, then is indulged
Curve arch is gradually formed to the precast concrete hollow block of arrangement, improves construction efficiency.
(4) construction cost is low.The utility model proposes prefabricated assembled arch in prefabrication process, without large-scale template and
Holder is transporting and is being not necessarily to that temporary support is arranged in hoisting process.Therefore, construction efficiency is high, greatly reduces construction cost.
In general, the utility model proposes a kind of prefabricated assembled arch, overcome the deficiencies in the prior art, have it is good
Good application prospect.

Specific implementation mode
The utility model is as shown in the picture, a kind of prefabricated assembled arch, it is characterised in that：The precast concrete of longitudinal arrangement
Hollow block 1 is connected by the fabric reinforced cement based material layer 2 for pouring at an upper portion thereof；It is characterized in that：It is two neighboring pre-
The angle of angle 3 between 1 side of concrete hollow block processed is determined according to the shape of design arch and curvature；It is prefabricated mixed
Groove 4 is arranged in the side of solidifying soil hollow block 1.
When implementation, first, according to the shape and curvature of design arch, two neighboring precast concrete hollow block 1 is determined
The angle of angle 3 between side；Then the precast concrete hollow block 1 made arranges along longitudinal direction, and by an upper portion thereof
Fabric reinforced cement based material layer 2 is poured, the precast concrete hollow block 1 of longitudinal arrangement is connected, is completed prefabricated.Having
In the hoisting process of body, carry out according to the following steps：
The first step：In the side of precast concrete hollow block 1, according to the lifting position mounting suspension member 6 of design, pendant 6 with
Centered on the precast concrete hollow block in centre position, it is arranged symmetrically；
Second step：One end of steel wire rope is connected on pendant 6, the other end is connected on the suspension hook of crane, is hung first
Intermediate precast concrete hollow block is played, under Gravitative Loads, fabric reinforced cement based material layer 2 is empty in intermediate prefabricated concrete
The seam crossing of heart block both sides is by curved cracking；Then, it produces relative rotation between precast concrete hollow block, angle 3 is closed；
Third walks：It centered on intermediate pendant, from the near to the distant, lifts by crane successively, until all precast concrete hollow blocks
Vacantly, all angles 3 between the precast concrete hollow block 1 of longitudinal arrangement are all closed, and forming curves encircle under Gravitative Loads；
4th step：Arch is placed on bridge pier, finally, binding material 5 is poured into the groove 4 of side, completes applying for arch
Work.
