Abstract

The utility model discloses a prefabricated four terrace with edge hollow component of pin -connected panel belong to harbour and waterway engineering technical field, and it includes mesa, lower mesa, prism, pre -buried screw rod, gasket and nut, and upper and lower mesa is trapezoid table or square, and trapezoidal post hole or square hole are left to the centre, upper and lower mesa thickness is the same, and the lower mesa length of side is greater than the mesa length of side, prismatic both ends are equipped with pre -buried screw rod, and splice through four prisms in upper and lower mesa four corners, prismatic specification homogeneous phase is same, for the quadrangular. Assemble wholly after the prefabrication. The utility model discloses can throw to fill out and form the dam body structure, replace conventional jackstone and sand material in bags. Have the great empty rate of passing through, the unit concrete has great surface area, can provide the good environment for water biological growth breeds. Have that the preparation is convenient, the construction is simple, cost low grade characteristics, and single component weight is adjustable, stability is high, the needs of building a dam under the adaptable different rivers conditions.

Description

A kind of novel precast splice type truncated rectangular pyramids hollow unit

Technical field

The utility model is applied to harbour and waterway engineering field, is specifically related to a kind of novel precast splice type truncated rectangular pyramids skyHeart member.

Background technology

In waterway regulation works, often adopt the management measure such as groynes, longitudinal dike, the multiplex jackstone of dam body and packed sand knotStructure, it is larger that engineering price is subject to material market to affect fluctuation. In performance renovating effect, because dam body air permeability rate is little, to partThe change of flow field and erosion and deposition condition is larger, is unfavorable for that aquatic organism perches and breeds, and is unfavorable for ecological protection and reparation.

Summary of the invention

In order to solve the deficiency in prior art or product, alleviate the strong disturbance of dam body near water body, build aquaticThe good environment that thing is perched, strengthens the ecological protection of engineering waters, and the utility model provides a kind of novel precast splice type four ribsPlatform hollow unit, can form dam body structure after loose throwing, replaces conventional jackstone and packed sand material. Profile is positive truncated rectangular pyramids, insideHollow, there is larger air permeability rate, unit concrete has larger surface area, can be aquatic organism growth and breeding good environment is provided.Member is plain concrete precast assembly structure, has the features such as easy to make, construction is simple, cost is low, and single construction weightCapable of regulating, stability is high, can adapt to the needs of building a dam under different flow conditions.

The utility model is to realize by following technical scheme:

A kind of novel precast splice type truncated rectangular pyramids hollow unit, it comprises upper table surface, following table and four prisms, its featureBe: upper and lower table top is bucking ladder or square, trapezoidal column hole or square hole are left in centre; Upper and lower mesa thickness phaseWith, following table is greater than upper table surface, and four jiaos of upper and lower table tops are by four prisms splicings, and described prism specification is all identical, is four ribsPost.

Described upper and lower table top and prism adopt prefabricated plain concrete structure, and four jiaos of upper and lower table top are reserved with respectively splicingHole, four prisms are fixed on the installing hole of upper and lower table top by pre embedded bolt, are spliced into a truncated rectangular pyramids member, truncated rectangular pyramidsComponent inside is hollow.

Described truncated rectangular pyramids structure body is six engraved structures.

The two ends of four described prisms are equipped with pre embedded bolt, and pre embedded bolt is through four jiaos of reserved peaces of upper and lower table topDress hole, more fixing upper and lower table top after being connected with pre embedded bolt with pad by nut.

Owing to having adopted above technical scheme, the utility model and existing product have following beneficial effect:

(1) throwing forms after dam body, and plain concrete structure durability is good, and near dam body, water disturbance is little, and renovating effect is good;

(2) truncated rectangular pyramids hollow unit has larger air permeability rate, and unit concrete has larger surface area, can be aquatic organism rawLong breeding provides good environment.

(3) single construction weight capable of regulating, stability is high, can adapt to the needs of building a dam under different flow conditions.

(4) member is plain concrete precast assembly structure, easy to make, and construction is simple, and the duration is very fast.

(5) the good material usage such as balance weight stone and sand, is subject to the market price to affect fluctuation little;

(6) construction costs is lower, and operating period maintenance workload is little.

Detailed description of the invention

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, underFace, in conjunction with concrete diagram, is further set forth the utility model.

Referring to Fig. 1, the utility model comprises upper table surface (1), following table (2), prism (3), splicing hole (4), pre embedded bolt(5), pad (6), nut (7).

Processing pre embedded bolt (5), pad (6) and nut (7). Prefabricated upper table surface (1), following table (2) and prism respectively(3), when prism (3) is prefabricated, imbed pre embedded bolt (5), four jiaos of reserved splicing holes (4) when upper table surface (1) and following table (2) are prefabricated.Concrete reaches after design strength, carries out integral assembling, and the member after assembled forms dam body through throwing.

For product is attractive in appearance, the inclination that has certain angle of prism (3), in the time that upper and lower table top (1), (2) are bucking ladder,Between upper and lower table top (1), (2), be similar, upper table surface (1) is less than following table (2), the angle of inclination of prism (3) equals,The angle at the trapezoidal base angle of following table (1), (2). When upper and lower table top is that (1), (2) are while being square, under upper table surface (1) is less thanTable top (2), the angle of inclination of prism (3) equals the angle of the angle of upper and lower table top (1), (2) line and horizontal plane formation.

More than show and described general principle of the present utility model, principal character and advantage of the present utility model.
