Abstract
The invention discloses a side wall large-scale embedded part fixing and supporting method of a cast-in-place concrete wall, and the side wall large-scale embedded part fixing and supporting method comprises the following steps that: 1) when the foundation of the cast-in-place concrete wall is constructed, upright post mounting embedded parts of an embedded part fixing and supporting frame are reserved on the outer side of the foundation of the wall; 2) a plurality of steel upright posts are positioned and mounted on the upright post mounting embedded parts, and all the steel upright posts form a line parallel to the cast-in-place concrete wall; 3) tie bars are connected between adjacent steel upright posts, and the embedded part fixing and supporting frame is formed by all the steel upright posts and all the tie bars; 4) side wall large-scale embedded parts are fixed on the embedded part fixing and supporting frame; 5) the construction of the cast-in-place concrete wall is completed; 6) after the strength of the concrete meets the requirement, the embedded part fixing and supporting frame is removed. According to the side wall large-scale embedded part fixing and supporting method, the structure that the embedded part fixing and supporting frame is mounted at the outer part of the concrete is adopted and the embedded part fixing and supporting frame can be completely recovered after the concrete is poured and formworks are removed; and meanwhile, the phenomenon that the fixing and supporting frame collides with reinforcing steel bars of the wall is avoided, and the strength of the concrete wall cannot be influenced.
Description
Technical field
The present invention relates to a kind of large-scale embedded part fixed support method, particularly relate to the large-scale embedded part fixed support of a kind of cast-in-situ concrete wall sidewall method.
Background technology
Slab caster is installed on the cast-in-situ concrete wall at each section of fan-shaped section straightening machine slide rail in the smelting engineering at present, because this slide rail installation accuracy is high, the wall concrete strength is required high.And this wall thickness is less relatively, highly higher, and embedded part is large-scale built-in fitting, requires this embedded part installation accuracy higher on the technology.In the conventional slab caster concrete wall construction of adopting in the past, generally adopt embedded part steel fixed mount to be installed in inside concrete.Because of designing reinforcing bar by technological requirement in the concrete, concerning concrete wall requires, satisfied the technology instructions for use; So cause the steel waste of embedded part steel fixed mount; In addition, because that reinforcing bar is set is comparatively intensive in this concrete wall, reinforcing bar and the embedded part steel fixed mount phenomenon of colliding can appear unavoidably; To occur and the fixed mount bar cutting phenomenon of colliding, and cause the cast-in-situ concrete wall to receive influence to a certain degree.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of can the economical with materials cost and can avoid that the cast-in-situ concrete wall receives influence the large-scale embedded part fixed support of cast-in-situ concrete wall sidewall method.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: the large-scale embedded part fixed support of a kind of cast-in-situ concrete wall sidewall method; May further comprise the steps: 1) when the foundation construction of cast-in-situ concrete wall, on the basis, embedded part is installed at the column of the outside of wall reservation embedded part fixing support rack; 2) at column some steel posts of location and installation on the embedded part are installed, all steel posts form the delegation parallel with the cast-in-situ concrete wall; 3) between the adjacent steel column, connect lacing wire, all steel posts form the embedded part fixing support rack with all lacing wires; 4) the large-scale embedded part of fixed sidewall on the embedded part fixing support rack; 5) construction of completion cast-in-situ concrete wall; 6) treat to remove the embedded part fixing support rack after concrete strength reaches requirement.
Said steel post is processed by H shaped steel.
Said lacing wire is processed by channel-section steel.
The large-scale embedded part of said sidewall is connected with the spot welding of said embedded part fixing support rack.
Advantage and good effect that the present invention has are: 1) adopt the embedded part fixing support rack to be installed in the outside structure of concrete; Treat to reclaim fully after form removal is accomplished in concreting; And can use at other positions, saved steel greatly, reached the green energy conservation effect; 2) in the concrete wall outside embedded part fixing support rack is installed; Avoided fixing support rack and the wall reinforcing bar phenomenon of colliding; Can not influence concrete wall intensity, and can save the concrete wall reinforcing bar and run into the steel that the fixing support rack place cuts off back overlap joint, also can reach energy-saving effect.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, as can be seen from Figure 1, the specification of the large-scale embedded part 1 of sidewall is 20 * 6200 * 850; Be large-scale embedded part; Simultaneously since segments of slab section slide rail installation accuracy require high, also very high to the embedded part required precision on the technology, therefore; The present invention proposes the large-scale embedded part fixed support of following cast-in-situ concrete wall sidewall method; See also Fig. 1～Fig. 5, the concrete steps of this method are: 1) when wall 2 foundation constructions, on the basis, in the outside of wall 2, reserve the column of embedded part fixing support rack embedded part is installed; 2) according to constructure scheme, at column some H shaped steel of location and installation column 3 on the embedded part is installed, must check the verticality and the positioning accuracy of this column during installation; All columns form the delegation parallel with the cast-in-situ concrete wall; Channel-section steel lacing wire 4 is installed after H shaped steel column 3 installs, and channel-section steel lacing wire 4 is connected employing and is welded to connect with H shaped steel, and fusion length must not be less than 150mm; Weld bead height and width all must not be less than 8mm; After treating that H shaped steel and channel-section steel all install, all columns form the embedded part fixing support rack with all lacing wires, and the large-scale embedded part of sidewall is installed on the embedded part fixing support rack; The large-scale embedded part of sidewall is connected employing spot welding and connects with the embedded part fixing support rack, make things convenient for the dismounting after concreting is accomplished.Treat to remove all templates and embedded part fixing support rack after concreting completion and intensity reach requirement.
Although combine accompanying drawing that the preferred embodiments of the present invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
