Description

Technical Field

[0001] The present invention relates to the technical field of floor casting molds, and particularly to a modular composite floor mold and its usage method. Background Art

[0002] At present, the prefabricated buildings advocated in the construction industry are to cast components such as columns, walls, beams, floors, and stairs in the factory after assembling steel formworks and tying steel bars. After reaching the demolding strength, they are demolded and placed until they reach a certain strength and then transported to the site, where the components are assembled together by means of reserved embedded parts or cast-in-place joints on the site. This process can not only reduce on-site operations, but also reduce noise, environmental pollution, waste discharge, etc., and is also known as green building.

[0003] A composite floor is a form of construction of prefabricated buildings, which is an assembled monolithic floor composed of a precast slab and a cast-in-place reinforced concrete layer. Among them, the precast slab is the lower slab containing bidirectional steel bars produced in the factory, and the cast-in-place reinforced concrete layer is the upper slab formed by on-site casting on the basis of the precast slab as the lower slab. The upper slab and the lower slab are combined into a whole slab, which is the composite floor.

[0004] In the prior art, the molds used in the precast slab projects of composite floors mainly have the following defects:

[0005] 1) There are many types of molds, and it is necessary to understand the type of the whole slab before and after assembly; it is necessary to customize steel molds in advance. Since the sizes of each slab are different and the contents of each project are also different, various side molds need to be customized during the production process of one project, and it is impossible to achieve random assembly to meet the design requirements of any slab.

[0006] 2) Usually, after the end of one project, the molds can basically not be reused and are sold as scrap iron. Especially when used as composite floors in public construction projects, the amortization ratio of the molds for the whole project is very large.

[0007] In view of the above-mentioned existing technical situation, the applicant of the present invention has made a large number of repeated and beneficial explorations, and finally the product has achieved effective results and formed the technical solution to be introduced below. Summary of the Invention

[0008] Therefore, the present invention provides a modular composite floor mold to solve the problems that the molds used in the precast slab projects of composite floors in the prior art cannot be randomly assembled to meet the design of any slab, and at the same time cannot be reused in different projects, resulting in a large consumption of construction costs.

Detailed implementation manners

[0063] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0064] Such as Figures 1 - 12As shown in the figure, the embodiment of the present invention provides a modular laminated floor slab mold, which can be placed on a supporting surface, including a first mold main board 1, a second mold main board 2, a mold end board 3, a fixed angle board 4 and a mold adjusting board 5. It can, according to the design parameters of the laminated floor slab, achieve the design requirements of different laminated floor slabs by arbitrarily assembling the modular molds, and can form a mold system that can be reused repeatedly in different projects, thus greatly saving the construction cost. The specific settings are as follows:

[0065] As Figures 1 - 2 shown, the first mold main board 1 has an extending direction, and the first mold main board 1 includes a first placing board 11 and a first shaping board 12 arranged along its extending direction; the first placing board 11 and the first shaping board 12 are integrally formed and perpendicular to each other; the first shaping board 12 is perpendicular to the supporting surface; a plurality of first rib plates 13 are uniformly fixed between the first placing board 11 and the first shaping board 12 to effectively ensure the structural stability of the first mold main board 1 when the board is formed.

[0066] The first shaping board 12 is uniformly provided with a plurality of first steel bar grooves 121 for burying steel bars in the board according to standards and enabling the steel bars to extend out of the mold, which is convenient for the installation between each board member.

[0067] On both sides of the first placing board 11 and the first shaping board 12 along the extending direction of the first mold main board 1, a first connecting end board 14 is respectively fixedly connected, so as to be fixedly connected with the mold end board 3 or the fixed angle board 4 or the mold adjusting board 5 through the first connecting end board 14 respectively.

[0068] Specifically, the first steel bar groove 121 adopts a V-shaped groove or a U-shaped groove. Refer to Figures 9 - 10 , it is set that the distance between the geometric midlines of two adjacent first steel bar grooves 121 is a (mm); the distances between the geometric midlines of the two side ends of the first shaping board 12 in its extending direction and its outermost first steel bar groove 121 are b (mm).

[0069] Among them, the value of a can be, but not limited to, 100, 110, 120,... 200; b + 15 ≤ a.

[0070] As Figure 1 , 3As shown, the second mold main board 2 has an extending direction, and the extending direction of the second mold main board 2 is perpendicular to that of the first mold main board 1; the second mold main board 2 includes a second placement board 21 and a second shaping board 22 arranged along its extending direction; the second placement board 21 and the second shaping board 22 are integrally formed and perpendicular to each other; the second shaping board 22 is perpendicular to the support surface; a number of second rib plates 23 are uniformly fixedly connected between the second placement board 21 and the second shaping board 22 to effectively ensure the structural stability of the second mold main board 2 during plate forming.

[0071] The second shaping board 22 is uniformly provided with a number of second steel bar grooves 221 for embedding steel bars in the plate according to standards and enabling the steel bars to extend out of the mold, facilitating the installation between individual plate components.

[0072] At both ends of the second placement board 21 and the second shaping board 22 along the extending direction of the second mold main board 2, a second connection end plate 24 is fixedly connected respectively for fixedly connecting with the mold end plate 3 or the fixed angle plate 4 or the mold adjustment plate 5 through the second connection end plate 24 respectively.

[0073] Specifically, the second steel bar groove 221 adopts a V-shaped groove or a U-shaped groove. Refer to Figures 9 - 10 , the distance between the geometric midlines of two adjacent second steel bar grooves 221 is set as a (mm); the distance between the geometric midlines of the second shaping board 22 and its outermost second steel bar groove 221 at both side ends in its extending direction is b (mm).

[0074] Among them, the value of a can be but is not limited to 100, 110, 120,... 200; b + 15 ≤ a.

[0075] As Figure 4 shown, the mold end plate 3 includes two end plate shaping boards 31, a predetermined distance is left between the two end plate shaping boards 31, and third connection end plates 34 are fixedly connected respectively between the side ends of the two end plate shaping boards 31 in a one-to-one correspondence. The third connection end plate 34 is perpendicular to the end plate shaping board 31 for fixedly connecting with the fixed angle plate 4 through one side of the third connection end plate 34 and fixedly connecting with the first connection end plate 14 or the second connection end plate 24 or the mold adjustment plate 5 through the other side of the third connection end plate 34.

[0076] The end plate shaping board 31 is provided with a third steel bar groove 32 and a fourth steel bar groove 33.

[0077] Specifically, both the third steel bar groove 32 and the fourth steel bar groove 33 adopt a V-shaped groove or a U-shaped groove. Among them, refer to Figures 9 - 10The distance between the geometric center line of the third steel bar groove 32 and the edge of the adjacent end plate shaping plate 31 is m (mm), and the value of m can be preferably 25.

[0078] The distance between the geometric center line of the third steel bar groove 32 and the geometric center line of the fourth steel bar groove 33 is n (mm). When the two mold end plates 3 are respectively located on both sides of the first mold main board 1 or the second mold main board 2, the corresponding n values of the two mold end plates 3 are n1 and n2 values respectively.

[0079] The distance between the geometric center line of the fourth steel bar groove 33 and the edge of the adjacent end plate shaping plate 31 is c (mm). The sum of the c value and the b value is equal to the a value, and c≥15.

[0080] Set the plate length of a plate body as L; the distances between adjacent two steel bars embedded in the plate body are equal (i.e., the distance is a value). And, since the steel bars on both side edges respectively need to leave a predetermined distance from the side ends of the plate body (i.e., m value, m adopts 25 mm), therefore, when the L value is a design floating value and the a value is a selected standard value, L - 25*2 - n*a is calculated, and the remaining distance obtained is basically not exactly an integer multiple of a. Therefore, the remaining distance is set as A.

[0081] According to the design requirements, the reinforcement intervals should be as symmetrical as possible. So the steel bars on both sides of the plate body should be arranged as symmetrically as possible. Therefore, the remaining distance A value is divided into two parts, that is, two values A1 and A2 are formed respectively located on both sides of the plate body (i.e., corresponding to n1 and n2 values in the mold end plate 3 respectively).

[0082] During the production process of the plate body, the production conditions and transportation conditions of the plate body will be considered to determine whether to produce a whole plate or split it into several plates (seamed plates), and the split seamed plates will be transported to the site for pouring.

[0083] Therefore, for a whole plate, it is possible that A1 = A2, that is, when using the mold end plate 3 in the mold for pouring, two mold end plates 3 with n1 = n2 can be selected.

[0084] For seamed plates, the steel bars extending out of the plate between the two plates need to be staggered to ensure the stability of the plate body after pouring. Therefore, as a preferred scheme of this embodiment, there is a difference between A1 and A2. At this time, for two plate bodies with the same plate length L and aligned, one of the plate bodies can coincide with the other plate body after rotating 180°, so that the same set of molds can be directly used for pouring.

[0085] Specifically, the difference range between A1 and A2 is between 20 mm and 30 mm, that is, A1 - A2 = ±20 - 30 mm, n1 - n2 = ±20 - 30 mm.

[0086] Both of the two end plate shaping plates 31 are provided with a third steel bar groove 32 and a fourth steel bar groove 33, so that the mold end plate 3 can be directly used in a mirror image or rotated by 180°.

[0087] More specifically, A1 + A2 also remains within a < A1 + A2 < 2a, that is, a < n1 + n2 < 2a.

[0088] According to the design requirements, when the designed interval of the steel bars in the plate body is a, the interval between two adjacent steel bars should be not less than 1 / 2*a. Therefore, if the part where n1 + n2 is greater than a is subtracted, then there must be a value in n1 and n2 that is less than 1 / 2*a, and one more steel bar will be used, wasting steel bars during mass production; when n1 + n2 > 2a, then there must be a value in n1 and n2 that is greater than a, which does not meet the design requirements.

[0089] In summary, in the splicing plate, n1 + n2 should meet a < n1 + n2 < 2a; n1 - n2 = ±20 - 30 mm.

[0090] When the common range of the a value is 100, 110,..., 200, the corresponding n1 and n2 values can be obtained, that is, the common ranges of n1 and n2 are both 40 - 200. Therefore, the mold end plate 3 with corresponding numerical values can be designed.

[0091] At the same time, since the mold end plate 3 is provided with two steel bar grooves, namely the third steel bar groove 32 and the fourth steel bar groove 33, this setting has higher structural adaptability compared to using one steel bar groove. For example, when the value of n1 or n2 is 40, the value of n1 or n2 includes the distance from the steel bar groove of the first mold main board 1 or the second mold main board 2 to the side end. Therefore, the distance from the steel bar groove of the mold end plate 3 to the side end of the mold end plate 3 is too small, making it unable to meet the minimum distance for effective fixation using bolts.

[0092] As Figure 5 shown, the fixing angle plate 4 includes an angle plate connecting end plate 41 and a support plate 42; the angle plate connecting end plate 41 is a right-angled bending plate, which is used to be fixedly connected to the first connecting end plate 14 and the second connecting end plate 24 or to two third connecting end plates 34 respectively through the two side ends of the right-angled bending plate in a one-to-one correspondence; the support plate 42 is fixedly arranged between the two side ends of the right-angled bending plate to form a triangular stable structure, greatly improving the connection stability of the fixing angle plate 4 between the connection structures.

[0093] As Figure 6 shown, mold adjusting plates 5 are respectively arranged between the first mold main board 1 and the second mold main board 2 and the mold end plate 3; specifically, referring to Figures 7 - 8, the mold adjusting plate 5 includes two adjusting plate shaping plates 51, a predetermined spacing is provided between the two adjusting plate shaping plates 51, and fourth connecting end plates 53 are fixedly connected between the side ends of the two adjusting plate shaping plates 51 in a one-to-one correspondence. The fourth connecting end plate 53 is perpendicular to the adjusting plate shaping plate 51, and is used to fixedly connect with the third connecting end plate 34 through the fourth connecting end plate 53 on one side, and fixedly connect with the first connecting end plate 14 or the second connecting end plate 24 or the fourth connecting end plate 53 through the fourth connecting end plate 53 on the other side.

[0094] The adjusting plate shaping plate 51 is provided with a fifth steel bar groove 52, and the fifth steel bar groove 52 is a V-shaped groove or a U-shaped groove. As Figure 10 shown, the geometric center lines of the fifth steel bar groove 52 and the distances between the two ends of the adjusting plate shaping plate 51 are b and c (mm) respectively, and b + c = a and c ≥ 15 are satisfied.

[0095] That is, the length of the adjusting plate shaping plate 51 is the length a between two adjacent first steel bar grooves 121 or two adjacent second steel bar grooves 221. The distance between the geometric center line of the fifth steel bar groove 52 and the geometric center line of the outermost first steel bar groove 121 of the first mold main board 1 is a. The distance between the geometric center line of the fifth steel bar groove 52 and the geometric center line of the outermost second steel bar groove 221 of the second mold main board 2 is a. The distance between the geometric center line of the fifth steel bar groove 52 and the geometric center line of the fourth steel bar groove 33 is a. In this way, when one or more a values are reduced on the basis of the preset length of the first mold main board 1 or the second mold main board 2, at least one mold adjusting plate 5 can be added to reach the designed board length.

[0096] Both of the two adjusting plate shaping plates 51 are provided with fifth steel bar grooves 52, so that the mold adjusting plate 5 can be directly used in a mirror image or rotated 180°.

[0097] It should be noted that the fixing methods between the first connecting end plate 14, the second connecting end plate 24, the third connecting end plate 34 and the fourth connecting end plate 53 include but are not limited to bolt fixing.

[0098] The using method of the modular laminated floor slab mold includes the following steps:

[0099] S1: According to the design requirements of the designed board length L, board width S and steel bar spacing a, select the first mold main board 1 with the interval between two adjacent first steel bar grooves 121 being a, and the second mold main board 2 with the interval between two adjacent second steel bar grooves 221 being a (the value of a is 100 - 200).

[0100] S2: Determine whether it is necessary to add a die adjustment plate 5 based on the plate length L and the plate width S on the basis of the first die main board 1 or the second die main board 2;

[0101] For example, if the length of the first die main board 1 or the second die main board 2 is 5a + 2b or 3a + 2b, and the designed plate length requirement reaches 6a + 2b or 4a + 2b, then add a die adjustment plate 5; Fix the fourth connection end plate 53 on one side of the die adjustment plate 5 to the first connection end plate 14 of the first die main board 1 or the second connection end plate 24 of the second die main board 2 by bolts.

[0102] When adding the die adjustment plate 5, make the distance c between the geometric center line of the fifth steel bar groove 52 and one end of the adjustment plate shaping plate 51, plus the distance b between the selected first die main board 1 or the second die main board 2 between its outermost steel bar groove and its corresponding side edge, equal to the selected steel bar spacing value a in S1.

[0103] S3: According to the design requirements of the designed plate length L, plate width S and steel bar spacing a, when m is selected as 25, determine L - 2*25 - n*a or S - 2*25 - n*a to obtain the corresponding A1 and A2 values, and respectively select die end plates 3 with n1 = A1 and n2 = A2, and fix the die end plates 3 corresponding to n1 and n2 to the two side ends of the first die main board 1 or the two side ends of the second die main board 2 respectively.

[0104] If a die adjustment plate 5 is added, then fix the die end plate 3 to the side end of the die adjustment plate 5 away from the first die main board 1 or the second die main board 2.

[0105] S4: Use the fixed angle plate 4 to fix the adjacent two die end plates 3 corresponding to the first die main board 1 and the second die main board 2 respectively by bolts.

[0106] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
