Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to an early-removal column head structure. Background Art

[0002] The "early dismantling system" is a novel construction solution. After the concrete pouring is completed, when the concrete reaches the required strength, the beam and slab keels and formwork are removed in advance, and the materials are transferred from the material transfer port to the upper layer. At this time, only the vertical poles are retained and the support heads are removed early, and the span of the beam and slab is divided into several small spans to reduce the stress of the beam and slab.

[0003] Specifically, the main features of the early dismantling system include: Fast material turnover: By dismantling the formwork and other materials in advance, the material turnover rate is accelerated, the overall investment in the formwork support system is reduced, and thus the construction requirements are met. Simple construction: The key node of the early dismantling system is the early dismantling head. By replacing some U-supports with early dismantling heads according to the in-depth design of the formwork, the conditions for early dismantling can be met. Low capital investment and high benefits: Only by replacing some early dismantling heads, the configuration of formwork and keels can be reduced by 1 / 3, reducing construction costs.

[0004] However, the early disassembly system also has some defects and shortcomings. For example, in the prior art, the early disassembly head is a key component for achieving quick disassembly, and its structure is complex and the cost is high. At the same time, due to the diversity of current buildings, the traditional early disassembly system mainly uses standardized parts, and its variability is small. Utility Model Content

[0026] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0027] like Figure 1-Figure 2As shown, an early-removal column capital structure includes an upper column capital mechanism, a lower column capital mechanism 2, and a beam support 6 arranged between the upper column capital mechanism and the lower column capital mechanism 2; the lower column capital mechanism 2 includes a connecting head 1 connected to the lower supporting column, and a reinforcing support rib 3 arranged between the connecting head 1 and the beam support 6; the beam support 6 includes a plurality of support plates connected in sequence, and a plurality of connecting seats 4 are arranged at the bottom of the support plates, and one end of the reinforcing support rib 3 extends into the connecting seat 4; the upper column capital mechanism includes an upper supporting plate 9, and a second connecting rod 7 connected between the upper supporting plate 9 and the innermost support plate.

[0028] Compared with the prior art, in the prior art, the early dismantling system is generally suitable for cast-in-place structures with simple structures and small loads. It is named because of its simple and quick support and dismantling, so it is also called the early dismantling support system. It generally includes cast-in-place formwork, standard formwork, customized wooden squares, early dismantling column heads, main beams, etc., among which the early dismantling column heads are the main parts used to install and receive these parts, and are used to dock support poles or support columns. However, in the prior art, the adjustable improvements to the column heads are mainly focused on the height adjustment direction of the early dismantling column heads, while there is a lack of improvements in the load-bearing capacity of the column heads and the placement of the main beams. Basically, only standard part formworks can be used, which is difficult to apply to the increasingly complex existing building facilities. In the present invention, the adjustability of the beam support 6 is improved, and the beam support 6 is configured to be assembled from a plurality of support plates. The number of support plates can be assembled as needed, and an adjustable reinforcing support rib 3 is provided between the beam support 6 and the connecting head 1. After the number of support plates is adjusted, the position of the reinforcing support rib 3 is changed to change the support point. The support point can be changed according to the adjustment of the support plate, thereby improving flexibility and stability.

[0029] The reinforcing support rib 3 includes an upper rod body 10 and a lower rod body 11, and one end of the upper rod body 10 is inserted into the connecting seat 4 and locked by bolts, and the other end of the upper rod body 10 is provided with a hollow connecting internal thread. One end of the lower rod body 11 is fixed on the connecting head 1, and the other end of the lower rod body 11 is provided with an external threaded connecting head 1 adapted to the upper rod body 10. The support point position is adapted to the adjustment of the number of pallets through the adjustable upper and lower rod body 11 structure. Specifically, the overall length of the reinforcing support rib 3 is adjusted by the thread engagement length between the upper and lower rod bodies 11, and the specific connecting seat 4 position where the upper rod body 10 is inserted is adjusted according to the number and design of the pallets, so as to effectively ensure the support capacity provided by the reinforcing support rib 3 and avoid the problem of insufficient support force after the number of pallets is increased.

[0030] The second connecting rod 7 is provided with a joint at both ends. Ear plates 8 are provided on the upper part of the innermost pallet and at the bottom of the upper support plate. The support capacity of the pallet after expansion is improved by pulling the second connecting rod 7. Specifically, when in use, the second connecting rod 7 can also be designed in the form of an upper and lower threaded rod, and the stretching position of the second connecting rod 7 can be adjusted according to the increase or decrease in the number of pallets.

[0031] A main beam placement plate is arranged in each of the pallets, and a splicing plate is arranged on the side of the placement plate. The splicing plate is provided with a plurality of docking holes. The splicing plates are arranged to connect adjacent pallets, simply by overlapping the splicing plates of two adjacent pallets and fastening them with bolts, and connecting a limit plate 5 or a limit nail or a similar limit structure at the position of the edge splicing plate.

[0032] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
