Abstract

The utility model provides a mutual fastening fastener of concrete post laying wood mould for construction, comprising four fasteners capable of fastening with each other and self fastening. The fastener comprises inner lining pieces with inclined planes outside, and fastening elements with inclined planes corresponding to the incline planes of the inner lining pieces inside. The fastening element is fixed at the two ends of the inner lining pieces, the transverse and longitudinal inner lining pieces can be fastened with each other in opposite direction. The fasteners can fasten with each other. During a concrete post laying wood mould, the wood mould is not susceptible to deformation, the pouring is convenient and the concrete post is high in quality.

Description

Building concrete post is built the wooden model formula securing member that links closely mutually

Technical field

The utility model relates to a kind of building field instrument, specifically a kind of wooden model securing member that uses when building square concrete post and building.

Background technology

Wooden form was used very extensively during the square concrete post of current building was built, and the fastening means of wooden model is in practice of construction, though method is more, technology is all more original and fall behind.Existing fastening means is stressed undesirable, and the concrete post of building often quality is also bad.Existing several embodiment is:

One, the internal mold of concrete post is prefabricated with pine and veneer, and during installation, internal mold adopts scaffolding steel pipe and steel fastener to fix, because the elastic deformation amount of steel pipe is bigger, pull bar must be established in general middle part.The shortcoming of this method is: 1, template is yielding when construction, and particularly when the concrete column dimension of building was big, during as default deficiency of pull bar or pull bar insufficient strength, the concrete post of building often was out of shape bigger, influences construction quality.2, one group of securing member generally can only be fixed the direction directions X or the Y direction of fixed level direction (promptly can only).3, template is preset, is installed and consume man-hour very much, and material consumption is bigger, and construction is made troubles, and therefore construction cost also increases simultaneously.

Two, the internal mold of concrete post is prefabricated with pine and veneer, and securing member adopts wooden square stock, mostly is pine.Securing member adopts the common mode nail joint to fix, the middle simultaneously pull bar (being generally iron wire or reinforcing bar) of also need establishing.The shortcoming of this method is: template is yielding when 1, constructing.Use when 2, this scheme is not suitable for bigger concrete post and builds.3, one group of securing member generally can only be fixed the direction directions X or the Y direction of fixed level direction (promptly can only).4, default, the installation of template consume man-hour very much, and material consumption is bigger, and particularly the waste of timber is very big.

Summary of the invention

The utility model provides a kind of building concrete post to build the wooden model formula securing member that links closely mutually, and the fastening mutually of this securing member makes concrete post wooden model in the process of building not yielding, and cast is convenient, the concrete post quality height of building.

Building concrete post is built the wooden model formula securing member that links closely mutually; form by four fasteners that can fasten the back self-tightening mutually; described fastener is made up of inner piece and the inboard Fastener that has the inclined-plane that matches with the inner piece inclined-plane that the outside has the inclined-plane; Fastener is fixed in the inner piece two ends, and horizontal inner piece can link closely mutually with vertical inner piece rightabout.

Stiffener can be set up in the outside of described inner piece and Fastener.

The utlity model has following advantage:

1. installation is convenient, fast, saves man-hour more than 50% than original method.

2. need not to establish intermediate draw bar, one group of securing member can be simultaneously fixing both direction, the i.e. directions X and the Y direction of fixed level direction simultaneously.

3. securing member is reusable, and material consumption is very little, saves construction cost.

4. the securing member science is stressed, and self-clinching is tight mutually, and the concrete post that adopts this stay in place formwork to build is had edges and corners, and is out of shape minimumly, and because of establishing pull bar, the surfacing of concrete post is bright and clean, and its quality obviously is better than the concrete post of building with the template of other fastening structures.

5. stiffener is set up in the outside of inner piece and Fastener, and is stressed with stiffener, is used for bigger concrete post and builds.

The specific embodiment

As Fig. 1,2,3,4; building concrete post is built the wooden model formula securing member that links closely mutually; form by four fasteners that can fasten the back self-tightening mutually; fastener is made up of inner piece 1 and the inboard Fastener 2 that has the inclined-plane 4 that matches with inner piece inclined-plane 3 that the outside has inclined-plane 3; Fastener 2 usefulness iron nails 5 are fixed in the two ends of inner piece 1; it is engaged that laterally the Fastener 2 of (directions X) relies on the inboard inclined-plane 4 ' of the Fastener 2 ' of the inclined-plane 3 of its inner piece sides and vertically (Y direction), during installation through knocking mutual fastening.

The utility model generally relatively is fit to the following concrete post of 300 * 300mm builds, and fastener adopts pine square stock and iron nail nail joint prefabricated, prefabricatedly carries out according to Fig. 2, Fig. 3, and iron nail 5 can increase in case of necessity in right amount.

When the concrete column dimension of building not simultaneously, the distance that can change Fastener 2 between fastener two is carried out prefabricated, to satisfy different construction needs.The size relative fixed of general concrete post, securing member that therefore can prefabricated various sizes is to adapt to the usefulness of different engineering constructions; And the utility model is reusable, will bring great convenience to construction.

During installation,, on the pad shelves square stock 6 of concrete post 7, nail on location crosspiece 8,, allow the mutual interlock in each inclined-plane of fastener, strike then tightly and get final product then by putting one group of fastener of the present utility model by the vertical distribute spacing requirement of concrete post.Need not to take again other measures.

With interior concrete post, the bottom is fastening with two groups of securing members at 4000mm for the primary concreting height, more than every rising 400mm with one group of fastening getting final product of securing member.

Other aspects of concrete post formwork for placing, as: verticality, planeness, allowable variation etc., should carry out according to relevant building standard when making template.

When the concrete post of being built is big, can be provided with stiffener 9 at the

inner piece

1 and 2 of the Fasteners of fastener, stiffener 9 is fixed in the inboard of inner piece 1 and Fastener 2, and increases the size of each member as required, and the prefabricated installation of fastener is undertaken by Fig. 7, Fig. 8, Fig. 9.It stressedly more is better than first kind of embodiment through strengthening the back, can bear 2000kg pressure through the side direction of test inner piece 1, and therefore strengthened securing member can adapt to 1000 * 1000mm (comprising) fully and builds with interior concrete post.
