Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a construction method for simply removing a foundation coupling beam bottom formwork. Background Art

[0002] In the current construction industry, especially in the field of industrial construction, many buildings are concrete frame structures, and the foundations are mostly designed with independent caps and connecting beams. The upper elevation of the foundation connecting beam is consistent with the upper elevation of the foundation, but the height of the connecting beam is less than the height of the foundation cap, resulting in a difference between the bottom elevation of the connecting beam and the bottom elevation of the foundation. Therefore, the connecting beam cannot be constructed at the same bottom elevation as the foundation. Therefore, a template must be installed under the connecting beam for the construction of the bottom reinforcement of the foundation connecting beam. Therefore, it is very difficult to remove the template at the bottom of the foundation connecting beam after the concrete pouring is completed, and the process of removing the template is likely to cause damage to the template, resulting in increased construction costs. For this purpose, a construction method for simply removing the bottom of a foundation connecting beam is provided. Summary of the invention

[0003] The present invention aims to solve the above-mentioned problem, thereby providing a construction method for easily removing the bottom formwork of a foundation coupling beam.

[0004] The present invention solves the above-mentioned problem by adopting the following technical solution:

[0005] A construction method for simply removing the bottom formwork of a foundation connecting beam is carried out in the following steps:

[0006] Step 1: Build a scaffolding, set up a foundation connecting beam bottom formwork positioning support frame below the foundation connecting beam to be poured and between the two foundations;

[0007] Step 2: Lay the foundation connecting beam bottom template above the positioning support frame. The foundation connecting beam bottom template adopts a two-section template with a gap between the two sections of the template. The top surface of the template is at the same height as the bottom elevation of the foundation connecting beam, and the opposite surfaces of the two sections of the template are both inclined surfaces;

[0008] Step 3: Install the bottom formwork of the independent foundation connecting beam at the interval between the two sections of the formwork. An independent support frame is used to support and fix the bottom formwork of the independent foundation connecting beam. The cross-section of the bottom formwork of the independent foundation connecting beam is an isosceles trapezoid. The inclined surfaces where the two isosceles sides are located are used in conjunction with the inclined surfaces of the bottom formwork of the two sections of the foundation connecting beam on both sides;

[0009] Step 4: Pour the concrete foundation connecting beam, and after solidification, remove the independent support frame and positioning support frame;

[0010] Step 5: Because the contact surface between the independent foundation connecting beam bottom formwork and the two sections of the foundation connecting beam bottom formwork on both sides is an inclined surface, and there is no support at the bottom of the foundation connecting beam bottom formwork and the independent foundation connecting beam bottom formwork, the independent foundation connecting beam bottom formwork can be easily removed, and then it is easier to remove the foundation connecting beam bottom formwork on both sides to complete the removal of the foundation connecting beam bottom formwork.

[0011] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0012] When the method described in the present invention is adopted for construction, when the formwork is removed, since the contact surfaces between the bottom formwork of the independent foundation connecting beam and the bottom formwork of the two sections of foundation connecting beams on both sides are inclined surfaces, it is more convenient to remove the formwork, and the time for removing the formwork can be effectively reduced. At the same time, the removal process is more labor-saving, and damage to the formwork due to violent removal is avoided, the repeated service life of the formwork is increased, and it is beneficial to save costs.

[0013] Preferably, a further technical solution of the present invention is:

[0014] The length of the bottom formwork of the independent foundation coupling beam is greater than the width of the foundation coupling beam to be cast, and both ends extend out of the two sides of the foundation coupling beam to be cast. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0021] See also Figure 1-Figure 4 A construction method for simply removing the bottom formwork of a foundation connecting beam is carried out in the following steps:

[0022] Step 1: See Figure 1, build a scaffolding, set up the foundation connecting beam bottom formwork 3 positioning support frame 2 below the foundation connecting beam 6 to be poured and between the two foundations 1;

[0023] Step 2: See Figure 2 , a foundation connecting beam bottom template 3 is laid above the positioning support frame 2. The foundation connecting beam bottom template 3 is a two-section template, with a gap between the two sections of the template. The top surface of the template is at the same height as the bottom elevation of the foundation connecting beam 6, and the opposite surfaces of the two sections of the template are both inclined surfaces;

[0024] Step 3: See Figure 3 , an independent foundation connecting beam bottom template 4 is installed at the interval between the two sections of the template, and an independent support frame 5 is used to support and fix the bottom of the independent foundation connecting beam template 4. The cross-section of the independent foundation connecting beam bottom template 4 is an isosceles trapezoid, and the inclined surfaces where the two isosceles sides are located are respectively used in conjunction with the inclined surfaces of the two sections of the foundation connecting beam bottom template 3 on both sides;

[0025] Step 4: pour the concrete foundation connecting beam 6, and after solidification, remove the independent support frame 5 and the positioning support frame 2;

[0026] Step 5: Since the contact surface between the independent foundation connecting beam bottom formwork 4 and the two sections of the foundation connecting beam bottom formwork 3 on both sides is an inclined surface, and there is no support at the bottom of the foundation connecting beam bottom formwork 3 and the independent foundation connecting beam bottom formwork 4, the independent foundation connecting beam bottom formwork 4 can be easily disassembled, and then the foundation connecting beam bottom formwork 3 on both sides can be disassembled more easily to complete the removal of the foundation connecting beam bottom formwork.

[0027] See also Figure 4 The length of the bottom template 4 of the independent foundation connecting beam is greater than the width of the foundation connecting beam 6 to be cast, and the two ends extend out of the two sides of the foundation connecting beam 6 to be cast, so that the bottom template 4 of the independent foundation connecting beam can be removed after the independent support frame 5 and the positioning support frame 2 are removed.

[0028] When the method described in the present invention is adopted for construction, when the formwork is removed, since the contact surfaces between the bottom formwork of the independent foundation connecting beam and the bottom formwork of the two sections of foundation connecting beams on both sides are inclined surfaces, it is more convenient to remove the formwork, and the time for removing the formwork can be effectively reduced. At the same time, the removal process is more labor-saving, and damage to the formwork due to violent removal is avoided, the repeated service life of the formwork is increased, and it is beneficial to save costs.

All equivalent changes made using the contents of the present specification and its drawings are included in the scope of rights of the present invention.
