Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a wooden formwork quick-disassembly support frame. Background Art

[0002] Conventional high-rise buildings often use more than three sets of formwork bottom formworks per standard floor, which not only fails to achieve the effect of cost saving, but also does not meet the requirements of green construction. In order to solve such problems, some projects use aluminum alloy formworks instead of wooden formworks. Although this improves efficiency and project quality, the cost of aluminum formworks is much higher than that of wooden formworks. The higher the floor, the lower the flat cost. Therefore, if conventional high-rise buildings want to save costs and improve material utilization, they need to make adjustments and innovations to technical solutions based on actual conditions. There are several problems in the existing technology:

[0003] ① The horizontal support formwork used in traditional wooden formwork construction is relatively large, generally three or four sets. The formwork and demoulding process is more complicated than that of the quick-release support system, and the material loss rate is higher;

[0004] ② The cost of aluminum formwork is high, especially for low- and medium-rise buildings, and secondly, the technical requirements for workers are also relatively strict;

[0005] ③Since the aluminum mold is a customized product, fewer design changes are required on site after customization, and the template cannot be greatly changed, especially in shape and size. Summary of the invention

[0006] In order to solve the above-mentioned problems, the utility model provides a wooden formwork quick-release support frame, which is composed of a quick-release support head, an adjustable screw support and a supporting upright pole to form a support system, wherein the adjustable screw is used to adjust the distance between the upright pole and the quick-release head to facilitate complete fitting to the bottom surface of the structure. The use of a quick-release wooden formwork combination reduces the loss of the formwork and improves the turnover rate of the formwork.

[0007] In order to achieve the above purpose, the specific technical solution of this application is as follows:

[0008] A wooden formwork quick-release support frame comprises a plurality of support uprights and disc-type steel pipe uprights, wherein the support uprights and the disc-type steel pipe uprights are arranged alternately, bottom supports are provided at the bottom of the support uprights and the disc-type steel pipe uprights, and top supports are provided above the support uprights; a quick-release support head is provided above the top support; a U-shaped top support is plugged into the top of the disc-type steel pipe upright, and the top support and the U-shaped top support are in the same horizontal plane, a main keel steel pipe is provided above the top support and the U-shaped top support, a longitudinal secondary keel wooden square is provided above the main keel steel pipe, and the secondary keel wooden square is provided with a wooden square template.

[0009] Based on the above technical features, further, a cross bar and a diagonal brace are connected between the support uprights and the disc-type steel pipe uprights.

[0010] Based on the above technical features, further, the top support is an adjustable screw support for adjusting the distance between the support pole and the quick-release support head to facilitate complete fit to the bottom surface of the wooden square template.

[0011] Based on the above technical features, preferably, the spacing between the support uprights is not greater than 1800 mm, and the spacing between the support uprights and the disc-type steel pipe uprights is not greater than 900 mm.

[0012] Based on the above technical features, preferably, the wooden square formwork is 15 mm thick and the outer surface is coated with a non-oily release agent.

[0013] Based on the above technical features, preferably, the size of the secondary keel wood is 40mm×90mm×400mm.

[0014] Based on the above technical features, preferably, the main keel steel pipe is φ48.6mm×3.0mm.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] The support system is composed of a quick-release support head, an adjustable screw support and a support pole. The adjustable screw is used to adjust the distance between the pole and the quick-release head to facilitate full fit to the bottom surface of the structure. The quick-release wooden formwork combination reduces the loss of the formwork and improves the turnover rate of the formwork.

[0017] Compared with aluminum molds, the cost is lower and the material processing time is shorter. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] like Figure 1 and Figure 2 As shown, a wooden formwork quick-release support frame comprises a plurality of support uprights 1 and disc-type steel pipe uprights 2, wherein the support uprights 1 and the disc-type steel pipe uprights 2 are arranged alternately. Preferably, the spacing between the support uprights is not greater than 1800 mm, and the spacing between the support uprights and the disc-type steel pipe uprights is not greater than 900 mm.

[0025] A bottom support 3 is provided at the bottom of the support upright 1 and the disc-type steel pipe upright 2, and a top support 4 is provided above the support upright; a quick-release support head 5 is provided above the top support 4, and the quick-release support head 5 is customized by welding a load-bearing block made of aluminum alloy with a screw, and its size is processed according to design requirements.

[0026] A U-shaped top support 6 is inserted into the top of the disc-shaped steel pipe upright 2, and the top support 4 and the U-shaped top support 6 are in the same horizontal plane. A main keel steel pipe 7 is arranged above the top support and the U-shaped top support, and a longitudinal secondary keel wood 8 is arranged above the main keel steel pipe 7, and the secondary keel wood is provided with a wood template 9.

[0027] Preferably, the top support 4 is an adjustable screw support, which is used to adjust the distance between the support upright and the quick-release support head, so as to completely fit the bottom surface of the wooden square template 9.

[0028] Furthermore, a cross bar 10 and a diagonal tie rod 11 are connected between the support uprights 1 and the disc-shaped steel pipe uprights 2 to further reinforce the support frame.

[0029] Preferably, the wooden square formwork 9 is 15 mm thick, and the outer surface is coated with a non-oily release agent, which can effectively protect the formwork and improve the turnover rate of the formwork.

[0032] Working principle:

[0033] According to the requirements of the specification, after the concrete strength reaches the design formwork removal conditions (when the span of the beam component is ≤8m, the concrete strength must reach at least 75%, and when the span of the plate component is ≤2m, the concrete strength must reach at least 50%), the support frame uprights are retained, and other support rods and the bottom plate formwork are removed. The removal order is: diagonal rod → horizontal rod → support uprights → main keel steel pipe → secondary keel wood → wood formwork. The remaining supports can be completely removed until the strength reaches the requirements for removing all supports. During this period, the removable parts are transported to the construction layer for turnover erection.
