Description

Wooden frame template

Technical Field

The invention relates to the technical field of concrete pouring formworks in constructional engineering, in particular to a wood frame formwork.

Background

The common templates in the cast-in-place concrete structure in the prior building field comprise a steel aluminum template and a traditional wood template, and the two templates respectively have advantages and disadvantages.

The steel-aluminum template has the advantages that: 1. high strength, tight assembly, difficult deformation and rigid and straight external corner. 2. Because can make in advance at the template factory according to the drawing and accomplish, then transport to the scene and directly assemble, for traditional plank sheathing, to same building, its template dismouting construction efficiency height under the same condition of floor structure is high.

However, steel aluminum forms also have the following disadvantages, including: 1. due to the fact that the self weight is large, hoisting equipment is needed to hoist on a construction site, and the hoisting equipment is occupied for a long time. 2. The material cost of the steel-aluminum alloy is originally high, the steel-aluminum alloy is only suitable for buildings with the same design, the steel-aluminum alloy is customized, and if the steel-aluminum alloy is used for buildings with different designs, the waste rate exceeds 30%, so the cost is further increased. 3. Because the degree of difficulty of the cutting change of metal is great, therefore steel aluminium template in case the design, its leeway of revising is very little, and the flexibility is relatively poor to improper dismouting or fall the collision damage and lead to the unable use of monoblock template.

Traditional plank sheathing is at on-the-spot processing and build and assemble, its advantage: 1. the system can be corrected conveniently according to the field condition, and has strong flexibility and wide adaptability. 2. The cost of the material itself is low.

But the wooden form has the following obvious disadvantages: 1. the template has low strength, more supporting structures needing to be prevented from deforming, complex formwork supporting operation and low construction efficiency, and is difficult to meet the requirement of continuously shortening the construction period. 2. The manufacturing and building work of the on-site wood pattern is time-consuming and labor-consuming, and is continuously improved along with the increase of the construction labor cost.

The wedge 650 is a right angle wedge structure, and includes two right angle sides and a bevel side. The right-angled edge at the upper end of the wedge 650 is the hammering end. When the clamp 600 is used for clamping two bars 200, the groove 201 can be arranged on the bar 200 at the position where the first clamping surface 622 and the second clamping surface 642 contact the bar 200, and the groove 201 enables the clamping table 621 and the clamping head 641 to be partially trapped in the groove, so that the sliding of the clamp 600 is reduced, the accurate positioning is ensured, and the clamping is firm.

As shown in fig. 22 to 25, the wood frame formwork 1 is applied to a beam formwork including a beam bottom formwork 14 and a beam side formwork 15 of a beam bottom. The side of the bars 200 at the periphery of the beam bottom formwork 14 is provided with a joint part 230, and the bottom bars 202 at the bottom of the beam side formwork 15, which are matched with the bars 200 of the beam bottom formwork 14, protrude out of the plate part 100 of the beam side formwork 15. The bottom bar 202 is provided with a mating portion 240 on the front side facing the plate member 100. The beam bottom template 14 and the beam side template 15 are spliced in a matched mode, and the split joint is quick and small. Further, the lower ends of the bottom bars 202 are located at the same level as the lower ends of the beam bottom forms 14, so that the beam bottom forms 14 and the bottom bars 202 can be supported at the same time in the support structure of the beam bottom forms, and the support structure can be simplified.

The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the invention, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the invention.
