Description

Technical Field

[0001] The utility model belongs to the technical field of formwork support construction, in particular to a combination device for single-side formwork support and a construction method. Background Art

[0002] With the development of social economy and the advancement of construction technology, today's construction field is no longer limited to the wooden formwork construction system. New formworks and supports such as aluminum formworks, large steel formworks, and plastic-coated formworks have gradually emerged, which have the advantages of simple structure, easy assembly and disassembly, and a wide range of applications.

[0003] However, the vertical structural formwork in all types of formwork is a tension-bearing system of formwork, tension bolts, and keels. That is, holes are opened on the formwork at certain intervals, and tension bolts are set through the structural entity through pre-buried sleeves to transfer the lateral pressure of the concrete on the formwork symmetrically and equally to the keels, and then evenly distribute it on the formwork surface. Its advantage is that there is no need to add side supports. Only the primary and secondary keels that transmit force continuously and uninterruptedly and the tension bolts with reasonable distribution can achieve the opposite offset of the side load. This method is only applicable to systems that can support the formwork on both sides of the structural entity. It has certain limitations when the horizontal dimension of the structure is too large or there is no space for formwork operation on one side of the structure. There are the following problems:

[0004] First, a large number of spare parts such as tension bolts are invested, and the construction process is complicated, which increases labor costs and also weakens the overall strength of the vertical structural entity to a certain extent.

[0005] 2. When the formwork support height is too high, the steel pipe support is prone to insufficient support strength, which leads to deformation of the formwork and cannot guarantee the quality of concrete construction. The concrete with quality problems needs to be polished twice in the later stage, which wastes manpower and material resources and increases the cost of construction measures.

[0006] 3. During the concrete pouring process, a separate scaffolding needs to be set up on the outside. There is no connection between the scaffolding and the formwork, which increases the risk during the concrete pouring process.

[0007] Fourth, it cannot be used multiple times, and the workload of assembly and disassembly is large. Utility Model Content

[0073] The construction method of this single-side formwork support combined device has the following construction steps:

[0074] Step 1. Install the embedded parts system: Install the ground embedded rods 21 before installing the structural formwork. An embedded part should be arranged at the starting point and the end point of the supporting object. The other spacings are determined according to the calculation of the concrete pouring load. When pre-buried, it is required to draw a line to ensure that the ground embedded rods 21 are on the same straight line.

[0075] Step 2: Install the single-sided panel: Lay out the edge of the support object in advance. When installing the single-sided panel 11, the lower end must be aligned with the edge of the support object, and use temporary steel pipe back ribs to support the single-sided panel 11.

[0076] Step 3. Install the single-sided support system: Assemble the right-angled triangle frame in the yard in advance, hoist it to the installation site, fix the right-angled triangle frame to the support system 3 at the rear, and then install the secondary keel 12 and main keel 13 on the outside of the formwork in sequence. At the same time, fasten the right-angled triangle frame to the single-sided formwork system 1. It is advisable to arrange a single-sided support at the starting point and the end point of the supported object. The remaining horizontal spacing is determined according to the calculation of the concrete pouring load.

[0077] Step 4: Fasten the embedded parts system: After installing the single-sided support system, install the connecting nut 22 and the external limit rod 23 of the embedded parts system. After installing five to six right-angled triangle frames, install the pressure beam steel 24 and the fixing parts 25 of the embedded parts system and fasten them.

[0078] Step 5. Adjust, tighten and check: Adjust the adjustment seat 6 of the right-angled triangle frame, and adjust the adjustment screw 62 until the upper end of the single-sided panel 11 is tilted about 5 mm inward toward the supporting object. Because the upper end of the single-sided support system will be slightly offset outward after the force is applied to the single-sided support system, tighten and check the embedded system again to ensure that there will be no leakage from the lower end of the template when pouring concrete.

[0079] Step 6: Installing the operating platform for people to walk on and pour concrete: Use steel pipes to build the operating platform 14 for people to stand, walk and operate when pouring concrete, and pour concrete inside the support object.

[0080] Step 7: Formwork and Support Removal: After concrete pouring is complete and strength meets regulatory requirements, the supports and formwork are removed. First, loosen support system 3, then loosen embedded component system 2.
