Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, and in particular to a structure and a construction method for protecting corners of traditional wooden molds. Background Art

[0002] In the construction process of the construction industry, traditional wooden formwork is often used for pouring and reinforcement. In the use of traditional wooden formwork, due to the violent demolding of the workers and the relatively weak corners of the wooden formwork, the wooden formwork is severely damaged due to the process of falling, dropping and colliding during demolding. In addition, during the transportation and handling of the wooden formwork, due to the lack of effective protection and protection of the wooden formwork, the corners of the wooden formwork are easily bumped and hit, resulting in a significant reduction in the service life of the wooden formwork and the number of turnover uses; the cost of tools and materials in the construction process is increased, and the frequent replacement of wooden formwork also increases the workload and working time of workers, which is not conducive to the rapid and efficient construction process.

[0003] Chinese patent application "CN201420071602.1 A wooden mold with protective corner sleeves" discloses a protective structure that protects the four corners of the wooden mold body by protective corner sleeves made of iron plates. Although it provides certain protection for the corners of the wooden mold, considering that the wooden mold needs to be spliced ​​or stacked during use, the thickness of the protective corner sleeves will not be too thick, so the protection of the corners of the wooden mold is also relatively limited. Long-term high impact force will cause the protective corner sleeves to deform and damage the wood of the wooden mold. Summary of the invention

[0004] In order to solve the problem that the traditional wooden mold corners lack protection measures in the prior art, which easily causes the corners to be damaged too quickly and the wooden mold turnover service life is not long, the present invention proposes a structure and construction method for protecting the traditional wooden mold corners.

[0005] A structure for protecting the edges and corners of a traditional wooden mold, comprising a wooden mold and a protective device covering the four right angles of the wooden mold, wherein the protective device comprises an "L"-shaped reinforcement frame arranged on the right-angled side of the wooden mold, an elastic buffer layer attached to the outside of the reinforcement frame, and an iron sheet protective layer at the right angle of the wooden mold and covering the reinforcement frame and the elastic buffer layer; the reinforcement frame and the elastic buffer layer are fixed at the right angle of the wooden mold, and the outer side of the elastic buffer layer is flush with the right angle side of the wooden mold; the iron sheet protective layer forms a triangular shell-like covering at the right angle of the wooden mold and is fixed to the wooden mold by rivets.

[0006] Furthermore, through holes are provided at corresponding positions on the reinforcing frame and the elastic buffer layer, and screws for fixing the wooden formwork, the reinforcing frame and the elastic buffer layer are provided in the through holes.

[0007] Furthermore, a sink is provided at the end of the through hole outside the elastic buffer layer, the head of the screw is located in the sink and a metal gasket is provided between the head of the screw and the bottom of the sink.

[0008] Furthermore, the reinforcing frame is a hard metal part and its cross section is "concave" shaped, and the part where the wooden mold and the reinforcing frame are in contact with each other is "convex" shaped to match the reinforcing frame.

[0009] Furthermore, the lengths of the two right-angled sides of the reinforcing frame are the same and are 15 to 20 cm.

[0010] Furthermore, the iron sheet protective layer includes an upper skin segment and a lower skin segment in the shape of a triangle, a side covering segment connecting the two right-angled sides of the upper skin segment and the lower skin segment, and a folded edge covering segment connected to the other right-angled side of the upper skin segment. The upper skin segment and the lower skin segment are respectively adhered to the upper and lower surfaces of the wooden mold, the side covering segment is adhered to the side between the upper and lower surfaces of the wooden mold, and the folded edge covering segment is bent 90° from the middle and respectively adhered to the side between the upper and lower surfaces and the lower surface of the wooden mold.

[0011] Furthermore, the thickness of the iron sheet protective layer is 0.05-0.1 mm.

[0012] A construction method for a structure for protecting corners of a traditional wooden formwork comprises the following steps:

[0013] Step 1: Make preliminary cuts at the four right angles of the wooden mold. The thickness of the cut is the sum of the thickness of the reinforcement frame and the elastic buffer layer. The length of the cut is greater than or equal to the length of the right angle side of the reinforcement frame.

[0014] Step 2, cutting or grinding the right angles of the cut wooden mold to form a shape that fits the inner side of the reinforcement frame;

[0015] Step 3, fixing and connecting the elastic buffer layer, the reinforcement frame and the wooden formwork by screws;

[0016] Step 4, cutting the iron sheet raw material into the shape of the iron sheet protective layer;

[0017] Step 5, bend the iron sheet protective layer and cover it on the four right angles of the wooden mold, and fix the iron sheet protective layer on the wooden mold by rivets on the upper and lower surfaces near the sides of the right angles of the wooden mold.

[0018] Furthermore, the step 4 specifically includes the following steps:

[0019] Step 4.1, cutting the whole sheet of iron sheet raw material into two rectangular blanks of the same size when the iron sheet protective layers are unfolded and placed diagonally;

[0020] Step 4.2, cut off two opposite corners of the rectangular blank isosceles, the length of the cut hypotenuse is the same as the width of the side covering section, and cut off the other two opposite corners of the rectangular blank isosceles, the length of the cut hypotenuse is the same as the width of the folding covering section;

[0021] Step 4.3, cutting the rectangular blank diagonally at the same cutting angle as the width of the folded edge covering section, and cutting off a rectangle in the middle to form the shape of the iron sheet protective layer;

[0022] Step 4.4, deburring the edge of the iron sheet protective layer.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention provides a structure and construction method for protecting the corners of traditional wooden molds. By setting a protective device wrapped at four right angles of the wooden mold in the structure of the traditional wooden mold corner protection, the corners of the wooden mold are effectively protected by three layers, wherein the reinforcing frame increases the structural strength of the corners of the wooden mold, and a high-strength hard metal part is added on the basis of the original wood that directly bears wear, so that the corners of the wooden mold have stronger wear and impact resistance.

[0025] The elastic buffer layer is provided to make the corners of the wooden mold have a certain toughness and elasticity, so as to buffer and weaken the impact force on the corners of the wooden mold to a certain extent, and further enhance the anti-damage ability of the corners of the wooden mold;

[0026] The iron sheet protective layer covers the reinforcing frame and the elastic buffer layer, which not only ensures the flatness of the wooden mold corners, but also increases the integrity of the wooden mold corners, making it less likely to fall off or wear out due to external forces.

[0027] The triple protection of the comprehensive protection device strengthens the edge and corner strength of the wooden formwork on the basis of its original structure, and the damage caused by the collision of the wooden formwork during transportation can be effectively avoided. When dismantling the formwork, the damage to the edges and corners caused by the workers' violent dismantling of the formwork and the falling to the ground will also be greatly reduced, thereby increasing the overall service life of the wooden formwork.

DETAILED DESCRIPTION

[0040] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments:

[0041] Embodiment 1

[0042] As shown in FIGS. 1 to 8 , a structure for protecting the edges and corners of a traditional wooden mold comprises a wooden mold 1 and a protective device covering the four right angles of the wooden mold 1, wherein the protective device comprises an “L”-shaped reinforcing frame 2 arranged on the right-angled side of the wooden mold 1, an elastic buffer layer 3 attached to the outside of the reinforcing frame 2, and an iron sheet protective layer 4 at the right angle of the wooden mold 1 and covering the reinforcing frame 2 and the elastic buffer layer 3, wherein the reinforcing frame 2 and the elastic buffer layer 3 are fixed at the right angle of the wooden mold 1 and the outer side of the elastic buffer layer 3 is flush with the right angle side of the wooden mold 1, and the iron sheet protective layer 4 forms a triangular shell-like covering at the right angle of the wooden mold 1 and is fixed to the wooden mold 1 by rivets 5.

[0043] By setting the protection device wrapped at the four right angles of the wooden mold 1 in the structure of the traditional wooden mold corner protection, the corners of the wooden mold 1 are effectively protected by three layers, wherein the reinforcing frame 2 increases the structural strength of the corners of the wooden mold 1, and adds high-strength hard metal parts on the basis of the original wood that directly bears the wear, so that the corners of the wooden mold 1 have stronger wear and impact resistance; by setting the elastic buffer layer 3, the corners of the wooden mold 1 have a certain toughness and elasticity, wherein the elastic buffer layer 3 can be made of rubber, plastic, other materials with buffering properties or synthetic materials, and the elastic buffer layer 3 buffers and weakens the impact force borne by the corners of the wooden mold 1 to a certain extent, further strengthening the damage resistance of the corners of the wooden mold 1; by setting the iron sheet protective layer 4, the reinforcing frame 2 and the elastic buffer layer 3 are both wrapped inside, which not only ensures the flatness of the corners of the wooden mold 1, but also increases the integrity of the corners of the wooden mold 1, making it less susceptible to external forces and causing the wood to fall off or wear;

[0044] As an implementation method, Figures 3 to 6 As shown, through holes 6 are provided at corresponding positions on the reinforcing frame 2 and the elastic buffer layer 3 , and screws 7 for fixing the wooden formwork 1 , the reinforcing frame 2 and the elastic buffer layer 3 are provided in the through holes 6 .

[0045] Specifically, a sink 8 is provided at the end of the through hole 6 outside the elastic buffer layer 3 , the head of the screw 7 is located in the sink 8 , and a metal gasket 9 is provided between the head of the screw 7 and the bottom of the sink 8 .

[0046] The reinforcing frame 2 and the elastic buffer layer 3 are reliably fixed at the corners of the wooden mold 1 by means of screws 7. The head of the screw 7 does not protrude from the side of the corner of the wooden mold 1 by the setting of the sinker 8, thereby ensuring that the installed protective device does not affect the flatness of the corner of the wooden mold 1. Since the elastic buffer layer 3 has certain toughness and elasticity and is soft in texture, in order to prevent the head of the screw 7 from sinking into the elastic buffer layer 3 and causing an unreliable connection when fixing with the screw 7, a metal gasket 9 is set between the bottom of the sinker 8 and the head of the screw 7.

[0047] As an implementation method, Figure 3 As shown, the reinforcing frame 2 is a hard metal part and its cross section is "concave" shaped, and the part where the wooden mold 1 fits with the reinforcing frame 2 is "convex" shaped to match the reinforcing frame 2.

[0048] Specifically, the lengths of the two right-angled sides of the reinforcing frame 2 are the same and are 15 to 20 cm.

[0049] It can be understood that by matching the “concave” shape of the reinforcing frame 2 with the “convex” shape of the wooden form 1 , the stability and connection strength of the reinforcing frame 2 and the wooden form 1 when they are fitted together are ensured.

[0050] As an implementation method, Figure 7 and Figure 8 As shown, the iron sheet protective layer 4 includes an upper skin segment 401 and a lower skin segment 402 in the shape of a triangle, a side covering segment 403 connecting the two right-angled sides of the upper skin segment 401 and the lower skin segment 402, and a folded edge covering segment 404 connected to the other right-angled side of the upper skin segment 401, the upper skin segment 401 and the lower skin segment 402 are respectively attached to the upper and lower surfaces of the wooden mold 1, the side covering segment 403 is attached to the side between the upper and lower surfaces of the wooden mold 1, and the folded edge covering segment 404 is bent 90° from the middle and respectively attached to the side between the upper and lower surfaces and the lower surface of the wooden mold 1.

[0051] Specifically, the thickness of the iron sheet protective layer 4 is 0.05-0.1 mm.

[0052] It can be understood that, by setting the iron sheet protective layer 4 of this shape, the corners of the wooden mold 1 are completely covered, and the shape of the iron sheet protective layer 4 is convenient for the covering operation and the manufacture and forming of the iron sheet protective layer 4 .

[0053] The triple protection of the comprehensive protection device strengthens the edge and corner strength of the wooden mold 1 on the basis of its original structure, and the damage caused by the collision of the wooden mold 1 during transportation can be effectively avoided; when removing the mold, the damage to the edges and corners caused by the workers' violent demolding of the wooden mold 1 falling to the ground will also be greatly reduced, thereby increasing the overall service life of the wooden mold 1.

[0057] Step 2, cutting or grinding the right angles of the cut wooden mold 1 to form a shape that fits the inner side of the reinforcing frame 2;

[0058] Step 3, the elastic buffer layer 3, the reinforcing frame 2 and the wooden form 1 are fixedly connected by screws 7;

[0059] Step 4, dividing and cutting the iron sheet raw material into the shape of the iron sheet protective layer 4;

[0060] Step 5, bend the iron sheet protective layer 4 and cover it on the four right angles of the wooden mold 1, and fix the iron sheet protective layer 4 on the wooden mold 1 through rivets 5 on the upper and lower surfaces near the sides of the right angles of the wooden mold 1.

[0064] Step 4.3, cutting the rectangular blank diagonally at the same cutting angle as the width of the folded edge covering section 404, and cutting off a rectangle in the middle to form the shape of the iron sheet protective layer 4;

[0065] Step 4.4, deburring the edge of the iron sheet protective layer 4.

[0066] Through the operation of step 4, the iron sheet material is conveniently cut into the shape of the iron sheet protective layer 4, such as Fig. 9 As shown, step 4.1 is to cut the iron sheet raw material into rectangular blanks with two iron sheet protective layers 4 placed diagonally;

[0067] like Fig.10 As shown, the pre-processed rectangular blank is further processed through step 4.2 to form the edge profiles of the side covering section 403 and the folding covering section 404;

[0068] like Fig.11 As shown, finally, the contour of the folded edge covering section 404 is cut and formed through step 4.3, and at the same time, the two iron sheet protective layers 4 are formed by separating the contour of the folded edge covering section 404;

[0069] Step 4.4 removes burrs on the edges after cutting and segmenting to prevent the remaining burrs from causing harm to workers.

[0070] In summary, by using the construction method of steps 1 to 4 above, the edges and corners of the wooden mold 1 are protected by the reinforcing frame 2, the elastic buffer layer 3 and the iron sheet protective layer 4 respectively, thereby strengthening the edge and corner strength and increasing the overall service life of the wooden mold 1. The structure formed for protecting the edges and corners of a traditional wooden mold is as described in Example 1, so the structure for protecting the edges and corners of a traditional wooden mold will not be repeated here.
