Abstract
The invention provides an accurate positioning and pouring method for fully distributing seat vent holes under an inclined plate structure. The technical problems that the existing hollow inclined plate with arc-shaped arranged seat vent holes is difficult to position the vent holes and is difficult to accurately reserve holes on the filling blocks are solved; and the technical problems that the vent hole sleeve is easy to shift when concrete is poured, the hollow slab is difficult to fix and float upwards and the slab ribs of the hollow slab are difficult to arrange are solved. Belongs to the technical field of building structure engineering.
Description
Technical Field
The invention relates to an accurate positioning and pouring method for fully distributing seat vent holes under an inclined plate structure, and belongs to the technical field of building structure engineering.
Background
The exchange development of art culture has higher and higher requirements on modern large-scale movie theater buildings, and the space of the movie theater buildings is various, so that the problem of structural complication and the control problem of quality in the construction process are caused. Such as conference halls, television relay audience halls, cinemas and the like, the indoor spaces of the buildings generally have the following functions that the steps of the seats are arranged in an arc shape, the step-by-step rising floor slabs are inclined plates, the large-span spaces are provided, positive pressure air supply holes are reserved on the ground below the seats, and the functional halls are generally realized by adopting cast-in-place solid plates or steel structures. The present theater building, the volleyball room of spectator's room and spectator's room below all need great space, and structural frame post can not extend spectator's room ground floor, therefore spectator's room ground need design for striding the hollow swash plate of prestressing force greatly, need reserve a large amount of seat ventilation holes under the seat on the floor, need insert the choke in the ventilation hole, the choke stretches into the seat leg, supplies air through the seat leg to it becomes vertical state and location accuracy to require the ventilation hole.
The ventilation holes reserved in the seats of the auditorium are large in number and arranged in an arc shape, so that the difficulty in accurately positioning the ventilation holes on the template is high; because the seat vent hole is in a vertical state, the filling block is parallel to the inclined plate, the vent hole is not vertical to the filling block, the filling block is made of light polyphenyl materials and is inflammable, large-scale opening on site is not suitable, and in addition, the vent holes are arranged in an arc shape, the positions of the vent holes on the filling block are different, so that the problem of how to accurately keep the holes on the filling block is solved; the ventilation hole template is fixed and how to ensure that the concrete can not run out when pouring is difficult.
Disclosure of Invention
The invention provides an accurate positioning and pouring method for fully distributing seat vent holes under an inclined plate structure, which aims to solve the technical problems that the existing seat vent holes are distributed in an arc shape, the positioning of the vent holes is difficult in the construction of a hollow inclined plate, and accurate hole reservation is difficult to perform on a filling block; and the technical problems that the vent hole sleeve is easy to shift when concrete is poured, the hollow slab is difficult to fix and float upwards and the slab ribs of the hollow slab are difficult to arrange are solved.
In order to achieve the purpose, the method for accurately positioning and pouring the seat ventilation holes fully distributed under the inclined plate structure is adopted, and the method is characterized in that L-shaped angle iron is distributed and fixed at the lower part of the peripheral outer wall of a rigid sleeve before use, and when the method is used, the rigid sleeve with the angle iron fixed is arranged at a set position and then connected with a template into a whole through a steel nail, namely the rigid sleeve is connected with the template into a whole, so that the rigid sleeve is prevented from deviating during concrete pouring.
Compared with the prior art, the method effectively solves the problem of deviation of the embedded rigid sleeve, does not increase any cost, avoids welding operation and reduces potential safety hazards. The method has the advantages that the method can be used once and for all, the pre-buried rigid sleeve is not required to deviate, the cost for opening the holes after the later structure is reduced, the engineering quality and the structure safety are ensured, and the method is suitable for popularization and application.

FIG. 1 is a cross-sectional view of the present invention;
fig. 2 is a plan view of the present invention.
Detailed Description
To make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, and it should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.
Examples
Referring to fig. 1 and 2, the embodiment provides an accurate positioning and pouring method for seat ventilation holes fully distributed under a sloping plate structure, before the method is used, the lower parts of the peripheral outer walls of a rigid sleeve 2 are distributed and fixed with L-shaped angle iron 3, when the method is used, the rigid sleeve 2 fixed with the angle iron is placed at a set position 5, the L-shaped angle iron 3 is connected with a template 1 into a whole through a steel nail 4, namely, the rigid sleeve 2 is connected with the template 1 into a whole, so that the rigid sleeve 2 is prevented from deviating during concrete pouring, the rigid sleeve 2 is pre-embedded and fixed, and the angle iron and the steel nail are used for fixing, so that the safety in the construction process is greatly improved, and the deviation is prevented due to transverse extrusion in the steel bar moving and concrete pouring processes.
The seat ventilation opening pre-embedding construction process specifically comprises the following steps:
1) placing a positioning wire: drawing the central point position of the opening on the template surface;
2) embedding a rigid sleeve 2: the rigid sleeve 2 with the L-shaped angle iron 3 fixed in advance is accurately placed on a set position 5 and fixed on the template 1 by a steel nail 4.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
Claims (1)
1. The utility model provides a full cloth seat ventilation hole accurate positioning pouring method under swash plate structure which characterized in that: before the method is used, L-shaped angle irons (3) are distributed and fixed at the lower parts of the peripheral outer walls of the rigid sleeves (2), when the method is used, the rigid sleeves (2) with the angle irons fixed are placed at set positions (5), the L-shaped angle irons (3) are connected with the templates (1) into a whole through steel nails (4), namely the rigid sleeves (2) are connected with the templates (1) into a whole, and therefore the rigid sleeves (2) are prevented from deviating during concrete pouring.
