Description

Stride and stride super large saddle shell plate of adding cross slab in

Technical Field

The utility model relates to a saddle shell plate, concretely relates to stride super large that adds cross slab and stride saddle shell plate in.

Background

When the span of the traditional saddle-shaped shell plate (hereinafter referred to as the shell plate) is larger than 27m and the load on the plate is larger, and the quality defect of the concrete member in the manufacturing process is added, the instability of the upper edge of the shell plate often occurs in the transportation, hoisting and using processes, the shell plate is cracked if the instability is small, and the potential safety hazard of the member is caused if the instability is large. In order to improve the situation, finite element analysis is carried out on the shell plates, and the analysis result shows that the main reason of the instability cracking of the upper edge of the shell plate is also due to the thin wall thickness of the shell plate and the large span of the shell plate without support by considering the initial defect of the first-order mode of the component and the nonlinearity of the material. If the shell plate is simply thickened, the self weight of the component is inevitably increased, and the material consumption is increased, so that the method is uneconomical.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a stride interior extra large saddle shell plate of striding that adds transverse baffle, stride the extra large saddle shell plate of striding of interior adding transverse baffle includes shell plate body and strides well transverse baffle, and the span of shell plate body is greater than 27m and the onboard load is big, strides well transverse baffle and is located the concave surface department that strides well position and be located the shell plate body of shell plate body, strides the length direction setting of well transverse baffle perpendicular to shell plate body.

Further, when the span of the shell plate body is larger than 33m, a supplementary transverse partition plate is additionally arranged at 1/4 of the span of the shell plate body, the supplementary transverse partition plate is positioned at the concave surface of the shell plate body and is arranged in the length direction perpendicular to the shell plate body, and a water passing hole is additionally arranged at the bottom of the supplementary transverse partition plate and in contact with the shell plate body.

Furthermore, bidirectional single-layer reinforcing bars are arranged in the midspan diaphragm plate and the supplement diaphragm plate, the reinforcing bars are perpendicular to each other, and the crossing positions of the reinforcing bars are fixed by binding wires.

Furthermore, the midspan diaphragm plate and the supplementary diaphragm plate are both arranged in a fan shape, and a plurality of additional steel bars are arranged in the fan-shaped linear direction.

Compared with the prior art, the utility model has the advantages as follows:

the utility model discloses increase the cross slab in the shell plate is striden, and the cross slab does not influence two-way along with slope drainage, is applicable to the span and is greater than 27m and the roof component of the load great, the great bearing capacity of needs on the board.

The utility model discloses simple structure, simple manufacture is convenient, and need not to increase the shell plate wall thickness, and economic nature is good, has certain market using value.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

The super large saddle shell plate spanning the inner transverse clapboard is suitable for roof members with span larger than 27m, large load on the plate and large bearing capacity. In addition, the wall thickness of the shell plate does not need to be increased, and the economy is good.

Referring to fig. 1 and 3, the oversized saddle-shaped shell plate spanning the inner transverse partition plate comprises a shell plate body and a middle transverse partition plate 1, wherein the span of the shell plate body is larger than 27m, the load on the plate is larger, the middle transverse partition plate 1 is positioned at the concave surface of the shell plate body and positioned at the middle position of the shell plate body, the middle transverse partition plate 1 is arranged in the length direction perpendicular to the shell plate body, and the middle transverse partition plate 1 does not affect bidirectional slope-following drainage.

As shown in fig. 2 and 4, when the span of the extra large span saddle-shaped shell plate spanning the internal addition diaphragm plate of the present embodiment is greater than 33m, a supplementary diaphragm plate 2 needs to be added at 1/4 of the span, and the supplementary diaphragm plate 2 is located at the concave surface of the shell plate body and is arranged perpendicular to the length direction of the shell plate body. The water through holes 5 are additionally arranged at the bottom of the supplementary diaphragm plate 2 (namely, at the contact part with the shell plate body), so that the supplementary diaphragm plate 2 can not influence the bidirectional slope-following drainage.

Midspan diaphragm 1 and supplementary diaphragm 2 all set up to fan-shaped, all are equipped with two-way individual layer arrangement of reinforcement 3 in the two, all are equipped with 2 additional reinforcing bars in fan-shaped straight line department.

The preparation method of the oversized saddle-shaped cross-over shell plate spanning the inner transverse clapboard comprises the following steps:

1. as in the conventional shell plate pouring, the shell plate body concrete of the saddle-shaped shell plate is poured firstly;

2. manufacturing a steel template for pouring the diaphragm plate, wherein a curved line at the lower end of the steel template is the same as the transverse curve of the bottom of the shell plate;

3. blanking reinforcing steel bars in the diaphragm plate;

4. before the initial setting of the shell plate concrete, scraping or chiseling the concrete at the transverse partition plate, inserting the steel bars for a certain depth, and firmly binding the crossed parts of the two-way steel bars by using binding wires;

5. placing the templates on the two sides of the diaphragm plate, pouring concrete of the diaphragm plate, vibrating tightly, and removing the templates after the strength is reached.

The above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
