Description

Composite mortar steel wire mesh prefabricated part

Technical Field

The utility model belongs to the technical field of the construction, concretely relates to compound mortar wire net prefab.

Background

With the development of the construction industry, the specific gravity of the precast concrete structure is increased day by day, and the specific gravity of the mold in the fabricated engineering is increased more and more. The wood template, the steel template and the aluminum alloy template are the most commonly used templates at present, and no matter how the functions of the templates are improved, one of the templates cannot be considered in quality, economy and progress.

The biggest problem for the form is the recycling of materials and the convenience of form removal, and under the current popularization of green building concept, the word of 'environmental protection' is already the mainstream of the building industry, for example, the wood form can be gradually deformed with the increase of the use times so as to be unusable, the processes of form removal and form assembly are relatively complicated, so the elimination of the wood form in the form market becomes a necessary trend in the future. For example, the use of steel moulds and aluminum alloy templates has great limitation, the templates cannot be greatly changed after being formed, if the templates need to be changed, the templates need to be communicated with a manufacturer in advance, and the templates are returned to the manufacturer for modification and then transported to a construction site, so that the progress of a construction period can be influenced to a great extent.

In actual engineering, the usage amount of traditional templates such as wood templates, steel templates and aluminum alloy templates is large in the early stage, the cost investment is high, the templates are relatively complex to disassemble and assemble, the consumed manpower and mechanical labor are large, the operation requirement on the same template worker is high, the used construction period is long, the requirement on industrial development is not met, and therefore an improvement mode is needed to achieve the purpose of saving the usage amount of the templates and meeting the building requirement on environmental protection.

SUMMERY OF THE UTILITY MODEL

The method aims to solve the problems that the prefabricated part saves the template in the production process, reduces the production cost, does not need to be disassembled, optimizes the working procedures and the like.

The utility model provides a compound mortar wire net prefab, this prefab are prefabricated post or precast beam, including the steel reinforcement cage, the outer cladding of steel reinforcement cage has the wire net, and the spraying sets up the whitewashing layer as the prefab side form on the wire net.

Furthermore, the steel wire mesh and the steel reinforcement cage are bound and fixed through binding wires.

Furthermore, the outer side of the steel wire mesh is reinforced by steel bars.

Furthermore, a bonding layer is arranged between the steel wire mesh and the guniting layer in a spraying mode.

Further, the guniting layer is composite mortar.

Preferably, the guniting layer of the prefabricated column is 25mm in thickness.

Compared with the prior art, the utility model discloses there is following advantage:

(1) The method adopts a composite mortar steel wire mesh technology, and flexibly molds the steel wire mesh according to the required size of a component by virtue of the characteristic that the steel wire mesh is easy to mold;

(2) The prefabricated part can directly spray composite mortar to the steel wire mesh by a mortar spraying technology, and a mortar spraying layer formed after the composite mortar is hardened is used as a side mold of the prefabricated column, so that the effect of pouring the prefabricated column without a template is achieved;

(3) The pouring process can be clearly observed through the steel wire mesh holes, so that the risk of the pores and the honeycomb is reduced, and meanwhile, the steel wire mesh mold forms a natural rough surface to provide an effective joint surface;

(4) The steel wire mesh can be directly poured in concrete, form removal is not needed, construction is convenient, production cost is reduced, working procedures are optimized, construction speed is accelerated, and construction period is shortened.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The composite mortar steel wire mesh prefabricated part shown in the figures 1-4 comprises a steel reinforcement cage 1, a steel wire mesh 2 is wrapped outside the steel reinforcement cage 1, and the steel wire mesh 2 is bound and fixed on the steel reinforcement cage 1 through binding wires. The reinforcement cage 1 mainly plays a role in tensile strength, the compressive strength of concrete is high, but the tensile strength is very low, and the reinforcement cage 1 plays a role in restraining the concrete in the prefabricated member, so that the reinforcement cage can bear certain axial tension.

Strengthen the deformation of preapring for an unfavorable turn of events with reinforcing bar 3 in the 2 outside of wire net, vertically place the prefab that reinforcing bar 3 was fixed, set up shotcrete layer 4 at the surface of prefab, the thickness setting of prefab type structure regulation is pressed to specific 4 thicknesses on shotcrete layer. The guniting layer 4 is composite mortar. It should be noted that the steel wire mesh 2 is coated with a binder before the gunite layer 4 is provided to improve the adhesion of the gunite layer to the steel wire mesh 2, and the binder is well known and will not be described in detail herein. The prefabricated members may be prefabricated columns, prefabricated beams or other structures as desired.

In the embodiment shown in fig. 1-4, the prefabricated member is a prefabricated column, and the specific steps of manufacturing the prefabricated column are as follows:
