Problems solved by technology

[0003] Aiming at the phenomenon that there is no special mold removal tool in the large formwork demoulding construction, there is a phenomenon of violent form removal, which causes damage to the formwork or the climbing frame and affects the molding quality of the concrete parts. The large formwork demoulding system and construction method of the present invention solve the problem of Solved the above problems and improved the efficiency of formwork construction

Embodiment 1

[0035] Such as figure 1 with figure 2 As shown, the large formwork 200 includes a formwork panel 210 and a formwork purlin 220 located on the back of the formwork panel 210 (the side facing the concrete to be poured is the front side, and vice versa). The ejection system 100 is used for the demolding construction of the large formwork 200.

[0036] Such as image 3 As shown, the ejection system 100 includes a support assembly 110 and an ejection assembly 120, wherein the support assembly 110 includes a support foot 111 and a support foot cover 112. Combine Figure 3 to Figure 5 As shown, the supporting foot 111 includes a supporting foot panel 111a and a supporting foot sleeve 111b arranged on the back of the supporting foot panel 111a. The large template 200 is provided with a reserved hole, and the supporting foot panel 111a is located in the reserved hole and its size is as predetermined Leave the holes to match. Combine image 3 , Image 6 , Figure 7 As shown, the supporti...

Embodiment 2

[0044] This embodiment provides a method of using the large template ejection system in the first embodiment. The following is combined Figure 1 to Figure 8 The method of use is further explained. The usage method specifically includes:

[0045] Install the large formwork ejection system 100, the supporting foot panel 111a is located in the reserved hole on the formwork panel 210 and the inner surface of the supporting foot panel 111a is flush with the inner surface of the formwork panel 210, between the supporting sleeve 111b and the connecting sleeve 112a Fixed by bolt 113;

[0046] Carry out concrete pouring construction;

[0047] After the concrete strength reaches the specified strength, carry out the withdrawal operation.

[0048] Further, carry out the withdrawal operation, including:

[0049] Release the bolt 113 between the supporting foot sleeve 111b and the connecting sleeve 112a, so that the supporting foot 111 is separated from the large template 210;

[0050] Clip the pa...

Abstract

The invention discloses a large formwork withdrawing system and a using method thereof, and belongs to the technical field of building construction. The formwork withdrawing system comprises a supporting assembly and a formwork withdrawing assembly. The supporting assembly comprises a supporting foot and a supporting foot cover. The supporting foot comprises a supporting foot face plate and a supporting foot sleeve arranged on the back portion of the supporting foot face plate. The supporting foot cover comprises a connecting sleeve and an expanded outer edge arranged at one end of the connecting sleeve. The supporting foot sleeve extends into the connecting sleeve, and the supporting foot sleeve and the connecting sleeve are fixed through a bolt. The formwork withdrawing assembly comprises clamping jaws, a formwork withdrawing sleeve, a shaft rod and a shaft handle. When the shaft handle is rotated, a pair of horizontal counter face is formed and transmitted to a formwork face plate and the supporting foot face plate, thus the formwork face plate and the supporting foot face plate are separated, namely the formwork face plate is separated from a concrete wall, formwork withdrawingoperation is achieved, and the violent formwork withdrawing problem can be avoided; and good probability and operability are achieved, and the large formwork construction efficiency is effectively improved.

Description

Technical field [0001] The invention relates to a large template ejection system and a use method thereof, and belongs to the technical field of building construction. Background technique [0002] Integral large formwork is a common formwork technology for the construction of concrete cast-in-place structures. Generally, there are structural types such as aluminum alloy formwork, steel formwork, and steel frame wooden formwork. In the construction of the concrete core tube of high-rise and super high-rise buildings, large formwork is generally used for vertical wall structure construction, and is often used in conjunction with hydraulic climbing formwork, integral steel platform, and integral lifting scaffolding. The construction of large formwork includes two main processes: mold closing and mold removal. When disassembling the mold, workers rarely dismantle the mold in pieces, that is, do not remove the connecting bolts between the template and the template, but often remove ...
