Description

A kind of arrangement of reinforcement formula buckle connection permanent beam template, concrete structure member and manufacture Method

Technical field

Patent of the present invention belongs to building template and concrete structure member and their manufacturing technology field, can be applied to The occasion such as industry and Civil structure, hydro-structure, port sea structure, bridges and culverts tunnel.

Background technology

In domestic construction field, industry generally makes with Civil structure, hydro-structure, port sea structure, bridges and culverts tunnel etc. With templates such as plank sheathing, steel forms, the unfavorable factors such as consumption is big, dismounting is inconvenient, turnover is costly, utilization rate is low be present.Pass Normal concrete surface is naturally exposed in structure in the case of system, and durability is relatively low.To solve the above problems, use high-durability Material makes permanent formwork and replaces conventional template to carry out the construction of building structure, is paid close attention to extensively by engineering circles.So And during permanent formwork is applied, the unsolved new problem of prior art is still present.For permanent beam template For, mainly include:1) shearing strength of panel and connecting portion how is ensured;2) how to solve the stirrup of permanent beam template Difficult arrangement and the problem of how to arrange stirrup;3) how quantification manufactures permanent formwork and its forms component, is allowed to meet The requirement of shearing strength.

The content of the invention

First purpose of the invention is to provide a kind of arrangement of reinforcement formula buckle connection permanent beam template, solves above-mentioned permanent beam The problem that during template use.Therefore, the present invention uses following technical scheme:

A kind of arrangement of reinforcement formula buckle connects permanent beam template, it is characterized in that, the arrangement of reinforcement formula permanent beam template is by panel (1) formed with connector (2);The panel has a first connecting portion position, and the connector has a second connecting portion position, and described Two connecting portions can fasten with the first connecting portion position of two pieces of panels after split, and the connector is in after split two pieces Panel pours this side of interface and is stacked with the first split position of two pieces of panels;The panel pours interface provided with first Projection, the connector pour interface provided with the 3rd projection;Connector and the panel cross section is in concave character type.The connection There is enhancing muscle part and panel itself and outside, and the enhancing muscle includes reinforcing bar.The enhancing muscle is used to match somebody with somebody instead of using described The enhancing muscle of muscle and stirrup is indulged in the concrete component that muscle formula permanent beam template pours.In the prior art, casting concrete structure Part needs to be poured after placing the enhancing muscle such as vertical muscle and stirrup in a template, is stripped after molding component;Using of the present invention Arrangement of reinforcement formula permanent formwork, can direct casting concrete in a template, without placing the additionally vertical enhancing such as muscle and stirrup muscle, and Without form removal after moulding by casting.There is one or more the first connecting portion position of the panel;The panel and connector are directly buckled Close or again by adhesive bond form needed for size and dimension template.

Further, the panel and connector are made from fiber reinforced cement-based material, the fibre reinforced cement Sill includes superhigh tenacity cement-base composite material.

Further, the both ends of the enhancing muscle for indulging muscle instead of the component of the connector are exposed, not by cement matrix Material is wrapped up.

Further, the second connecting portion position of connector sets the groove of fastening, and the first connecting portion position of panel is set The second of fastening is raised.

Another object of the present invention is to provide a kind of manufacture method of above-mentioned arrangement of reinforcement formula permanent beam template, therefore, this hair It is bright to use following technical scheme:

It need to meet that following shear-carrying capacity calculates in the component to require:

In above formula, V is the target shear-carrying capacity of the concrete structure member, and b is that the permanent formwork is recessed The distance between inwall of font cross section two side, h are the height of the permanent formwork, fcIt is the cylinder of casting concrete Body compression strength, As1It is the total face in section for the enhancing muscle for replacing the component stirrup in same section outside permanent formwork panel Product, fy1It is the shear strength for the enhancing muscle for replacing the component stirrup in same section outside permanent formwork panel, s1It is edge The spacing of the enhancing muscle of the component stirrup is replaced outside the permanent formwork panel of component length direction, t is that permanent formwork is recessed The thickness of the side wall of font cross section, As2It is the replacement structure of the single interior of permanent formwork panel in same section The section gross area of the enhancing muscle of part stirrup, fy2It is that permanent formwork panel itself replaces the component stirrup in same section Strengthen the shear strength of muscle, s2It is the enhancing muscle that the component stirrup is replaced along component length direction permanent formwork panel itself Spacing, fspIt is the split tensile strength of the fiber reinforced cement-based material.

A kind of arrangement of reinforcement formula buckle connection permanent beam template of the present invention, which can adopt, to be manufactured by the following method, according to above-mentioned Manufacture method determine parameters, manufactured by the way of pouring the parameters for meeting above-mentioned manufacture method connector and Panel.

Another object of the present invention is to provide a kind of concrete structure member with above-mentioned permanent formwork.Therefore, this Invention uses following technical scheme:

The shaped main body that it is formed including the use of above-mentioned permanent beam template casting concrete, permanent beam template is in shape The concreting of main body is connected as a single entity after condensing with shaped main body;Further, the parameters in template press above-mentioned system Make method determination.

Due to using technical solution of the present invention, can obtain it is a kind of it is with good strength and switching performance, pouring knot The permanent beam template of muscle and stirrup is indulged during structure component without additionally configuring.It ensure that the shearing strength of panel and connecting portion; Solves the stirrup Layout Problem of permanent beam template;Quantification manufactures permanent formwork and its forms component, is allowed to meet to resist Cut the requirement of intensity.At the same time, the enhancing muscle of the component stirrup is replaced outside panel, and the structure is replaced on connector Part indulges the enhancing muscle of muscle, combination of the two, instead of the overlap joint muscle between connector and panel, and further ensure connection The intensity at place.On this basis, technical scheme of the present invention greatly simplify the pouring construction (nothing using permanent beam template Vertical muscle and stirrup need to be arranged) so that not only fabrication schedule is more simple, quality is higher for concrete structure member, cost is lower.This The described permanent formwork of invention can carry out industrialized production, and its manufacture method is also the scale application of permanent formwork Technical support is provided, is had broad application prospects.
